    [0001] The present invention relates to a lawnmower provided with a support frame which is connected to a rear part of a vehicle body; and a grass catcher which is supported on the support frame so as to be able to pivot about a transverse shaft so as to switch between a grass collection position and a dump position. In a lawn mower of this type, the tilting between the dump position and the grass collection position of the lawn mower is achieved by using a dump jack. A conventional example is disclosed in Japanese Patent Application Laid-open 2001-95344.
    [0002] The lawn mower described in the above document is provided with a pair of left and right vertical support racks which are connected to a rear portion of a machine frame; a riser frame that is vertically movably connected to the left and right pair of vertical support frames using a vertical member; a grass catcher that is supported on the climbing / lowering frame; and an opening and closing cylinder provided on a left side of the grass catcher.
    [0003] The grass catcher is rotatably supported about a transverse support point on a rear end portion of a longitudinally oriented member of the up / down frame. The open / close cylinder is disposed between a grass catcher reinforcement member and the longitudinally oriented member of the up / down frame, and rotates the grass catcher upwardly about the support point to to a dump position, or pivot the grass catcher downwardly around the support point to a grass collection position. In the lawn mower described above, when the conventional technique described is used to allow a dump jack to tilt the grass catcher between the grass collection position and the dump position, problems tend to occur. to appear relative to the number of dump cylinders that are required and to the positions to which the grass catcher is tilted. More specifically, the use of the technique described above causes the emptying cylinder to be positioned on a lateral outer side of the grass catcher. In this case, when there are fewer emptying jacks provided, the pivoting of the grass catcher as realized above by the dump jack occurs on one side of the grass catcher, which stops rotating. in a regular way. In order to avoid this problem, dump cylinders must be provided on both sides of the grass catcher, and the number of dump cylinders required increases. It is an object of the present invention to provide a lawn mower in which cut grass can be emptied from a grass catcher using a small number of dump cylinders, and in which the grass catcher can be as low as possible. A lawn mower includes a vehicle body which is supported by a plurality of wheels; a support frame which is connected to a rear portion of the vehicle body; a grass catcher which is supported on the support frame so as to be pivoted between a grass collection position and a dump position about an axis oriented in the transverse direction of the vehicle body, the collector grass having a lower surface; a swivel body which is connected to a rotating shaft of the grass catcher to be rotated in unison so as to tilt the grass catcher between the grass collection position and the dump position; and a jack connected to the pivoting body and the support frame; the swivel body and the jack being disposed under the grass catcher in the grass collecting position, and the jack extending along the bottom surface of the grass catcher.
    [0004] The dump jack rotates the swivel body under the grass catcher, so that the swivel body causes the rotatable support shaft to rotate, and the grass catcher is tilted to the grass collection position or the grass catcher. dump position. As a result, the dump jack is disposed in or near a central portion of the grass catcher in the transverse direction, so that the grass catcher can be smoothly tilted to the position of the grass catcher. grass collection by the emptying cylinder, even when the number of emptying cylinders required is reduced. As a result, when the grass catcher collects grass, the dump jack is positioned along or near the bottom wall of the grass catcher, and the height at which the grass catcher is disposed is remarkably reduced. In this embodiment, the lower surface of the grass catcher is preferably formed in a concave portion which is formed in a bottom wall of the grass catcher, and is generally downwardly oriented when the grass catcher is in the grass collection position; and when the grass catcher is in the grass collecting position, the pivoting body and the jack are disposed within the concave portion.
    [0005] In this embodiment, the jack preferably has a longitudinal direction in which the jack extends; the pivoting body and the jack are connected by a pivot shaft; and, in a side view, an angle formed by a straight line connecting the rotation shaft and the pivot shaft and the longitudinal direction of the jack exceeds 90 ° in a process in which the grass catcher is moved from the grass collection position to the dump position.
    [0006] As a result, the actuating force applied by the jack on the pivoting body can be more effectively utilized to cause the pivot shaft to rotate. In this embodiment, the lawn mower preferably has an operator zone; a motor disposed in front of the operator zone in which the multiplicity of wheels has a pair of front wheels and a pair of rear wheels; a mower unit disposed between the pair of front wheels and the pair of rear wheels; and a pipe extending between the mower unit and the grass catcher such that the pipe extends along a longitudinal direction to a position between the pair of rear wheels. In this embodiment, the lawn mower preferably comprises the lower wall of the grass catcher which is generally inclined rearwardly and upwardly in a side view when the grass catcher is in the collecting position of the grass catcher. 'grass.
    [0007] In this embodiment, the bottom wall of the grass catcher is preferably generally inclined rearwardly and upwardly in a side view when the grass catcher is in the grass collection position.
    [0008] In this embodiment, the jack is preferably disposed at a position behind the lower surface of the grass catcher.

Embodiments of the present invention will be described below with reference to the drawings. Figure 1 is an overall side view of a lawn mower according to one embodiment of the present invention. As shown in FIG. 1, the lawnmower according to one embodiment of the present invention is provided with a self-propelled self-propelled vehicle which is propelled by a pair of steerable and drive front wheels 1, 1, and a pair of rear-wheel-drive wheels 2, 2; a mower unit 20 which is connected via a lift mechanism 4 to a vehicle body frame 3 of the self-propelled vehicle between the front wheels and the rear wheels; and a grass collection portion 30 which is equipped with a grass catcher 31 which is positioned behind the vehicle body of the self-propelled vehicle.
    [0010] The self-propelled vehicle is also provided not only with the pair of left and right front wheels 1, 1 and the pair of left and right rear wheels 2, 2, but also with a driving source, in which a motor 5 is mounted, and which is provided on a front part of the vehicle body so as to transmit a driving force to the front wheels 1 and the rear wheels 2; an actuating part which is equipped with an operator's seat 6 provided on a rear part of the vehicle body; a PTO shaft 8 which is supported by a driving front wheel casing 7 and is disposed in the longitudinal direction of the vehicle body; and a conveying line 9 which passes between the left and right rear wheels 2 in the longitudinal direction of the vehicle body. The PTO shaft 8 is driven by a driving force which is transmitted from an output shaft of the engine 5 via a transmission belt 10. The driving force is transmitted to a blade drive mechanism 21 of the mower unit 20 through a rotary shaft 11. The PTO shaft 8 is rotatably supported about an axis which is aligned with the axis of oscillation, which is oriented in the longitudinal direction of the vehicle, and wherein the driving front wheel housing 7 oscillates with respect to the vehicle body frame 3. The lifting mechanism 4 is provided with a pair of left and right front oscillating arms 4a 4a which connect the vehicle body frame 3 and a front portion of a cutting blade housing 22 of the mower unit 20; a pair of left and right rear swing arms 4b, 4b which connect the vehicle body frame 3 and a rear portion of the cutting blade housing 22 of the mower unit 20; a link 4c which connects the front swingarm 4a and the rear swingarm 4b on the left side; and a link 4c which. connects the front swingarm 4a and the rear swingarm 4b on the right side. The pair of left and right rear oscillating arms 4b, 4b moves in association with a hydraulic cylinder (not shown) via an associated displacement member 12. More specifically, the lifting mechanism 4 is caused to oscillate towards up and down with respect to the vehicle body frame 3 through the hydraulic cylinder. The mower unit 20 is thus lowered to a lowered operating state in which a gauge wheel 23 comes into contact with the ground surface, or raised to a raised idle state in which the gauge wheel is lifted out of the way. of the ground. When the mower unit 20 is placed in the lowered operating state and the self-propelled vehicle is operated, the mower unit 20 performs a cutting process as described below.
    [0011] More specifically, the mower unit 20 has a plurality of cutting blades 24 positioned within the cutting blade housing 22 along the transverse direction of the vehicle body. The blades 24 are driven by the blade drive mechanism 21 to rotate about axles oriented in the vertical direction of the vehicle body, and cut the grass. A flow of transport air generated by the rotation of the cutting blades 24 ejects the grass cut by the blades into the conveying line 9 through a cut grass outlet 25, which is positioned in a central portion of the blade housing cutting 22 in the transverse direction of the vehicle body. The conveying line 9 is made to communicate with the cut grass outlet 25 of the mower unit 20 and a cut grass entrance 32 of the grass catcher 31. The cut grass ejected by the grass outlet cut off (* 1) is sent to the grass catcher 31 by the transport air stream of the cutting blades 24.
    [0012] As shown in Fig. 1, the grass collection portion 30 is not only provided with a grass catcher 31, but also with a support frame 50 which has a fixed frame 33 which is connected to a grass catcher 31. rear portion of the vehicle body frame 3; rise / fall cylinders 34 which are connected to a pair of left and right up / down arms 52 of the support frame; a dump jack 35 which is supported on a holding frame 53 of the support frame 50; and tank opening / closing bars 36 which are provided on both side sides of the grass catcher 31. As shown in Fig. 2, the grass catcher 31 is not only provided with the inlet of the grass catcher 31. cut grass 32, but also a discharge outlet 37 provided on the grass catcher 31 towards the rear of the vehicle body, and a cover body 38 which opens and closes the emptying outlet 37. As this is shown in Figures 2 and 3, the grass catcher 31 is provided with a concave portion 40, which is provided on a lower wall 39 of the grass catcher. The concave portion 40 is positioned in a central portion of the bottom wall 39 along the transverse direction, opens downwardly from the grass catcher, and is in the form of a groove along the longitudinal direction of the lower wall 39. The concave portion 40 is formed with a shallow depth that approaches the front of the bottom wall 39. The cover body 38 is supported on a frame body 42 of the grass catcher 31 by the intermediate lid support body 41 which are positioned on both sides of the grass catcher 31. The pair of lid support bodies. left and right 41, 41 is rotatably connected to the frame body 42 via connecting pins 43. The pair of left and right cover support bodies 41, 41 is pivotally actuated upwardly and downwardly relative to the grass catcher 31, about an axis of the connecting pins 43 which is oriented in the transverse direction relative to the vehicle body, and the lid body 38 thus opens and closes the emptying outlet 37. As shown in FIG. 2, the support frame 50 is not only provided with the fixed frame 33 and the support frame 53, but also with a pair of upper and lower up / down arms 51, 52, which extend rearward of the vehicle body from a pair of left and right main racks 33a, 33a of the fixed frame 33, which are oriented in the vertical direction of the vehicle body.
    [0013] As shown in FIGS. 2 and 3, the fixed frame 33 is provided not only with the pair of left and right main frames 33a, 33a, but also with a connecting frame 33b, which is oriented in the transverse direction of the vehicle body. The connecting frame 33b connects the pair of left and right main frames 33a, 33a at an upper end portion, a middle portion, and a lower end portion of the fixed frame 33. The pair of left and right main racks 33a, 33a is removably connected via a pair of upper and lower connecting members 44, 44 to a support portion 3a in the form of a plate member connected to the vehicle body frame 3. The fixed frame 33 is thus connected to the vehicle body frame 3.
    [0014] As shown in FIGS. 2 and 3, the pair of upper and lower up / down arms 51, 52 is supported via a connecting shaft 54 on support portions 33c so as to be raised and lowered pivotally. The support portions 33c are provided on upper ends of the main frames 33a. As shown in FIGS. 2, 3 and 4, the holding frame 53 comprises a connecting plate 57 which is connected to distal end portions of the upper and lower up / down pair of arms 51, 52 on each other. the left side ; a connecting plate 57 which is connected to distal end portions of the upper and lower up / down arms 51, 52 on the right side; and a single link 58 and two lower plates 59 which are connected transversely to the pair of left and right connecting plates 57, 57. The holding frame 53 also has cylinder support plates 60, 60, also serving as covers. of the jack, which are formed from a pair of left and right metal plates which are secured transversely to the link 58 to the lower plates 59. The pair of left and right jack support plates 60, 60 and the pair of plates left and right connection connectors 57, 57 rotatably support a rotatable support shaft 62 which is integrally and rotatably connected to the lower wall 39 of the grass catcher 31 via a pair of left connecting plates and right 61, 61. The support frame 50 thus supports the grass catcher 31 so as to be able to pivot upwards and downwards about an axis P of the rotary shaft 62 in the transverse direction of the vehicle body.
    [0015] The pair of left and right connection plates 61, 61 is removably connected to the lower wall 39 of the grass catcher 31 by a connecting bolt. The grass catcher 31 can be removed from and mounted on the support frame 50 between the connecting plates 61 and the bottom wall 39. The up / down cylinders 34 are connected to a support 55 provided on the climbing arm. downhill 52 from the pair of upper and lower up / down arms 51, 52; and a support 56 provided on the main frame 33a. The up / down arms 51, 52 pivot upwardly and downwardly relative to the fixed frame 33, and the grass catcher 31 is thus raised and lowered relative to the vehicle body.
    [0016] The dump jack 35 is connected to a front end portion of the pair of left and right jack support plates 60, 60, and a pair of left and right left and right arm pivoting bodies 63, 63, which are connected to each other. integrally and rotatably to the rotary support shaft 62 between the pair of left and right cylinder support plates 60, 60. The pair of left and right pivoting bodies 63, 63 pivots about an axis P of the rotary support shaft 62, the rotatable support shaft 62 is thus rotated, and the grass catcher 31 pivots up and down about the axis P oriented in the transverse direction of the vehicle body. The tank opening / closing bars 36 are connected to a connecting shaft 64 which connects the lower up / down arm 52 and the connecting plates 57; and an actuating arm 65 on which the cover supporting bodies 41 are integrally and rotatably provided. The grass catcher 31 is pivoted relative to the support frame 50, so that the pivoting force of the grass catcher 31 is used as an actuating force, so that the cover body 38 is open. and closed. More specifically, the grass catcher 31 is vertically movably supported by the support frame 50 about an axis P oriented in the transverse direction of the vehicle body, so as to be able to tilt towards a collecting position. grass or a dump position. The pair of left and right up / down cylinders 34, 34 and a single output cylinder 35 are used to tilt the grass catcher to a grass collection position, a low dump position, or a dump position. in height. More specifically, Fig. 2 is a side view of the grass catcher 31 tilted into the grass collection position. As shown in FIG. 2, the pair of left / right up / down cylinders 34, 34 are controlled to retract (toward the lowered side), and the dump jack 35 is controlled to retract (towards the grass collection side). As a result, the pair of left and right up / down cylinders 34, 34 lower the pair of upper and lower up / down arms 51, 52 relative to the fixed frame 33, and the grass catcher 31 is thus lowered. relative to the vehicle body. The emptying cylinder 35 causes the pivoting bodies 63 to pivot and the rotary shaft 62 to rotate, so that the grass catcher 31 is caused to pivot towards the front of the vehicle body, about the P axis. oriented in the transverse direction of the vehicle body. As a result, the cut grass inlet 32 of the grass catcher 31 is made to communicate with an outlet of the conveying pipe 9, the lower wall 39 of the grass catcher 31 extends transversely to the bottom plate 59 of the holding frame 53, and the grass catcher 31 is tilted to the grass collection position. At this stage, the cover body 38 of the grass catcher 31 is tilted to a closed state by the pivoting of the lid support bodies 41 made by the pair of left and right tank opening / closing bars 36. The grass catcher 31 retrieves and thus collects the cut grass delivered by the transport pipe 9. In the state in which the grass catcher 31 is tilted towards the grass collection position, the emptying cylinder 35 the pair of left and right swivel bodies 63, 63, and and the right manifold manifold the pair of left jack support plates 60, 60 enter the concave portion 40 of the grass 31, and are positioned under the grass 31 while the center of gravity of the grass is lowered. Figure 5 is a side view. a state in which the grass catcher 31 is tilted to the low dump position. As shown in FIG. 5, the pair of left and right up / down cylinders 34, 34 are stopped in a retracted state, and the dump jack 35 is driven out (toward the dump side). As a result, the emptying cylinder 35 causes the pivoting bodies 63 to pivot and causes the rotary shaft 62 to rotate. The grass catcher 31 thus pivots towards the rear of the vehicle body, around the axis P oriented in the transverse direction of the vehicle body. As a result, the cut grass inlet 32 of the grass catcher 31 is moved up and back away from the outlet of the conveying pipe 9, and facing upwardly relative to the vehicle body. The emptying outlet 37 of the grass catcher 31 is oriented downwards with respect to the vehicle body, and the grass catcher 31 is brought into the low dump position. The cover body 38 of the grass catcher 31 is then rotated to an open state by the pivoting of the lid support bodies 41 made by the pair of left and right tank opening / closing bars 36, 36. As a result, the grass that has accumulated in the grass catcher 31 falls unassisted through the dump outlet 37, and is thus emptied. Fig. 6 is a side view of a state in which the grass catcher 31 is tilted to the dump position. As shown in FIG. 6, the pair of left and right up / down cylinders 34, 34 are controlled to exit (toward the lift side), and the dump jack 35 is controlled to exit ( to the emptying side). As a result, the pair of left and right up / down cylinders 34, 34 raise the pair of upper and lower up / down arms 51, 52 relative to the fixed frame 33, and the grass catcher 31 is thus high relative to the vehicle body. The emptying cylinder 35 causes the pivoting bodies 63 to pivot and causes the rotary shaft 62 to rotate. The grass catcher 31 thus pivots towards the rear of the vehicle body, around the axis P oriented in the transverse direction of the vehicle body. As a result, the complete grass catcher 31 is separated rearward and upward above the outlet of the transport pipe 9, and the cut grass inlet 32 of the grass catcher 31 is oriented towards the top of the vehicle body. The dump outlet 37 of the grass catcher 31 is oriented downwardly relative to the vehicle body, and the grass catcher 31 is brought into the dump position. At this point, the cover body 38 of the grass catcher 31 is tilted to an open state by the pivoting of the lid support bodies 41, as achieved by the pair of left tank opening / closing bars. and straight 36, 36. As a result, the grass that has accumulated in the grass catcher 31 falls unassisted through the dump outlet 37, and is thus emptied.
    [0017] Other Embodiments According to another alternative embodiment of the present invention, instead of the support frame 50 described in the above embodiment, a structure is used in which the grass catcher 31 is supported so as to pivotably tilted between a grass collection position and a low dump position, without being vertically movable. The objects of the present invention can also be achieved in this case.
