    () TRACTOR
    one
    The invention relates to the tractor industry, in particular to the construction of the tractor safety frame.
    The closest to the invention according to the technical solution is a tractor, comprising a safety cage, mounted vertically and including a front frame in the shape of an arch, mounted across the tractor on its frame in front of the seat and made detachable from the upper and lower parts connected between a level higher than the upper part of the steering wheel, and an L-shaped rear part, the horizontal shelf of which is located above the seat, the vertical shelf behind the seat, and its lower end is detachably fixed to the center the rear part of the tractor by means of fasteners, and the top frame tOВ of the known tractor, the rear part of the frame is separated from the front frame and connected to the top frame, hinged and located between
    .. 2:.
    upper sections of the front frame and the back.
    A disadvantage of the known construction is the possibility of damage to parts of the safety cage when overturning the tractor, which can lead to injury to the driver.
    The purpose of the invention is to increase safety.
    10 This goal is achieved by the fact that the rear part of the tractor is made in the form of a rod and is located in the plane passing through the longitudinal symmetry of the tractor, and its end is fixed in the central upper part of the front frame, while the front frame and rear frame are provided with connecting elements for detachable connection with the floor 2 (the mountable upper frame.
    FIG. 1 shows the proposed tractor, a side view not of FIG. 2 anchorage of the front rollcage to the tractor chassis, axonometric projection; Fig. A knot of detachable fastening of parts of the front frame, vertical section; in fig. And .- section A-A in FIG. 3 in FIG. 5 — tractor (another embodiment of the safety cage); in fig. 6 - the same, with the attached rear tool and awning; in fig. 7 is the same, front view, in FIG. 8 - security frame with connecting parts and removable awning, axonometric projection ..
    The agricultural tractor 1 comprises a skeleton 2, an engine 3 mounted on it in front of it, front and rear wheels k, a driver's seat 5, additional equipment, in particular a clutch housing 6, a steering wheel 7 as well as a safety cage installed vertically front frame 8 and rear 9.
    The frame 8 of the frame is U-shaped and fixed across the tractor on its frame in front of the seat 5. The lower ends of the frame 8 are fixed on the outer ends of the cantilever elements 10 rigidly connected with the side brackets 11 fixed on the frame 2 and the transverse flange of the clutch housing 6 . The front frame 8 has a height that provides the location of the space B for placing the driver t, preferably below the plane c-in (FIG. 1) j passing through the upper edge of this frame 8 and the upper rear edge of the tractor housing. Space B has the form of a triangle formed by the frame 2 of the tractor, frame 8 and is indicated by the plane c. The elements 10 are of increased strength in order to be able to install working equipment on them, for example plows.
    The frame 8 of the frame is filled with a detachable of the upper 12 and lower 13 parts connected to each other at the same level as the upper steering wheel 7, for example, the horizontal cross member Ik, but lower than the damage of the driver's eye.
    The fastening of the lower ends of the frame 8 (Fig. 2) to the elements 10 is carried out through a 1-shaped | b plate 15 rigidly fixed on the outer end of the element 10, and an L-shaped plate 16 with an upper protrusion 17 having a central opening 18, for making weld that is rigidly fixed on each bottom
    the end of the lower part 13 of the front frame, while both plates are interconnected and rigidly connected with bolts 19.
     ensuring sufficient strength of the frame 8 in the longitudinal direction of the tractor on both its sides are installed, the struts 20, fixed with ends to the middle sections of the lower frame 13 and the engine subframe.
    To both ends of the cross-beam Il (Fig. 3i t) having a tubular cross-section, the end caps 21 are rigidly attached, facing with a convex side outward to mate with the outer surface of the tubular cantilever elements of the lower part 13 of the front frame.
    Before fixing the part 13 and each cover 21 on the convex side of the latter, the nut 22 is rigidly attached, the axis of symmetry of which must coincide with the longitudinal axis of the lower part 13 of the front frame after installation. The bolt 5 23 can be screwed into the nut 22 on the opposite side of the cantilever element of the lower part 13 of the frame 8 through the corresponding holes in it. When screwing in the crossmember I, the lateral surface of the end cover 21 can be easily welded to the cantilever element, i.e. Provides a reliable connection of parts by a combination of threaded connection and welding.
    The detachable connection of the upper 12 and lower 13 parts of the front frame 8 (Fig. 3) is carried out using a common for both parts of an insert made with holes 25. In one of which a bolt 26 with a nut 27 is installed, and in the other - a bolt 23.
    The described implementation of frame 8 of the frame ensures that the space B required for placing the driver is preserved, even when the tractor is tilted sideways or turned over, ensuring the safety of the driver who can get out of the tractor to avoid injury.

    The rear part 9 of the tractor safety cage (Figs. 5-8) prevents damage in the event of lateral tipping. The rear part 9 is L-shaped, its horizontal shelf is located above the driver's seat 5, and the vertical shelf is behind the seat. The front end of the rear part is rigidly fixed in the central upper part of the front part 12 of the frame 8, and its lower end is detachably fixed in the center of the rear part of the tractor on the frame 28, rigidly attached to the rear part of the frame 2 by means of fasteners. The rear part 9 can be made integral of the two parts connected by fasteners. The frame may be provided with an upper removable frame 23 for accommodating the awning 30, which may be pulled over with a fastening harness on the frame 29 for protection from sun and rain. On the upper frame there are crowns. 31 for detachable fastening them to counter-brackets 32 fixed on the front 8 and rear 9 frames of the safety cage. The tent 30 can be pre-assembled on the upper frame 29, its installation can be adjusted, and installation and disassembly are easy and quick compared to directly installing it on the frame 8 and the rear part 9 of the frame. In FIG. 6 and 7 depict the described tractor with mounted rotary tillage equipment 33 for tillage, containing a rotating shaft 3, mounted in housing 35 and provided with tillage teeth B 3 rigidly attached to it. The equipment 33 is attached to the tractor by means of a hinged mechanism with a hydraulic actuator for raising and lowering the levers 37, located on both sides with the possibility of locking them in intermediate positions of the working equipment. An upwardly extending hook 38 is fastened on the subframe 28, and for fastening the equipment 33, a chain 39 is passed between the upper part of the latter and the hook 37, which can be stretched when the tractor 1 moves forward on the road or back across the field, while the equipment 33 up into a non-working position. Thus, it is mechanically maintained, for example, in the event of an emergency damage to the hydraulic system and to prevent the working equipment from hitting the ground. The described tractor performance both makes the driver safe at 166 accidents, for example, when the tractor rolls over on a slope the driver and his safe release from under the tractor without receiving, in addition, the design of the safety cage increases the driver's comfort when using the rear mounted Claims of the invention A tractor comprising a safety cage mounted vertically and including a front frame in the shape of an arch fixed across the tractor on its frame in front of the seat and made detachable from the upper and lower parts interconnected at a level higher than the upper part the steering wheel and the L-shaped rear part, the horizontal shelf of which is located above the seat, the vertical shelf behind the seat, and its lower end is detachably fixed in the center of the rear part of the tractor The connecting parts and the upper frame, characterized in that, in order to increase safety, the rear part is designed as a rod and is located in a plane passing through the longitudinal axis of symmetry of the tractor, and its front end is fixed in the central upper part of the front frame, wherein the front frame and the rear part of the frame are provided with connecting elements for releasably connecting with said upper frame.
