    A crop gathering head 10 including crop gathering belt 11, 12 of reinforced elastomeric material and its associated driving sprocket 30 and idler sheave 50 is described. The belt 11 or 12, sprocket 30 and sheave 50 system may be used to convey crops into a combine. The belt 11 or 12 includes a plurality of cleats 20 of elastomeric material on its top surface 18 and a plurality of equally spaced driving lugs 24 of elastomeric material on its bottom surface 19. The sprocket 30 has first and second sides 31, 32 respectively and comprises a plurality of equally spaced apart radially projecting teeth 33 separated by first and second cavities 34, 34 min , respectively. The first cavities 34 are open only to the first side 31 of the sprocket 30. The second cavities 34 min are open only to the second side 32 of the sprocket 30. The depth D of each cavity exceeds the height H of each driving lug 24 of the belt 11 or 12 and the cavities 34, 34 min are shaped such that foreign material, for example, corn kernels, mud and ice do not clog the driving sprockets 30 and belts 11 or 12 and disable the system. Each belt 11 or 12 is also entrained about an idler sheave 50 that includes a cylindrical hub 51 having a pair of axially spaced radially projecting flanges 52, 53 respectively thereon. The inner side surfaces 54 of the flanges 52, 53 converge in a direction toward the axis of rotation 55 of the sheave 50. Each flange 52 or 53 is interruped in the circumferential direction of the sheave 50 to provide a self-cleaning effect upon engagement with its associated belt 11 or 12.

    FIELD OF THE INVENTION The invention relates to agricultural machinery industry and can be used in devices for moving agricultural crops, such as corn stalks.
    The purpose of the invention is to increase reliability in operation, as well as to reduce noise and vibration.
    Fig, 1 shows the feeder, top view; FIG. 2 shows a portion of an endless elastic band; Fig. 3 shows the mating of a tape with a leading sprocket; in Fig, 4 - leading sprocket; FIG. 5 is a sectional view of FIG. 4; Fig 6 - a pulley; Fig. 7 shows the mating of a belt with a pulley.
    The feeding device can be made with two adjacent conveyors 1, Each conveyor 1 contains an endless elastic belt 4 mounted on a driving sprocket 2 and a pulley 3, reinforced by longitudinal inelastic cords 5 (FIG. 3) arranged in the middle part of its section and evenly spaced along its length with highly elastic gripping fingers 6, the Belts 4 of both conveyors 1 are rotatably mounted in one plane, and their working branches are located above
    19 is not a multiple of the step of the protrusions 26; The longitudinal section of the ZP 6 has the shape of a trapezoid with a large base on the surface of the tape 4; The projections 26 have the shape of a truncated tetrahedral pyramid. In each of the ZP 6 there is a hole of a trapezoidal shape, the axis of which is parallel to the outer the surface of the tape 4 and perpendicular to its longitudinal axis; The height of the protrusions 26 is less than the height of the teeth 9. When the device is operated, the crop is removed and the RFP 6 is captured and moved by the movement of the tape 4 and the pulley 3. are from places with straight zheny etenty 4 OT 2 and the pulley 3, 1, s, n, p, ly, 7 yl.

    The asterisk 2 has the gripping elements placed uniformly around its circumference, each of which is made in the form of a radial tooth 9 connected to each of the adjacent teeth 9 by means of a jumper 10 positioned asterisks 2 along one of the end faces 11 and 12 jumpers 10 are arranged with alternating sides 11 and 12 of their placement,
    5 Thus, cavities are formed between the teeth 9, each of which is open from one of the end sides 11 and 12, and closed by a jumper 10 on the other, the surface of the base0 VIA 13 of each cavity is inclined to
    the axis 14 of rotation of the sprocket 2 in the direction from the jumper 10 corresponding to this cavity in order to facilitate the self-cleaning of the sprocket 2, Jumper
     10 is connected to the surface of the base 13 by a rounded surface 15 also to facilitate self-cleaning. The base 13 is matched with sides 1.6 and 17 of the corresponding teeth 9 along
    0
    the curved surfaces or the base itself 13 is filled with a curved surface (Fig 4),
    3
    The pulley 3 consists of a cylindrical sleeve 18 with radial slots 19, executed in two rows, placed at opposite end sides 20 and 21 of pulley 3, 11, faces 19 of one row and offset; in the circumferential direction relative to the slots 19 of the other row
    The surface 22 of the slot T9 of one row, facing the surface 23 of the slot 19 of the other row, is located at an acute angle cL to this surface (FIG. 7), whose apex is directed to the axis of rotation 24 of the pulley
    The longitudinal section of each gripping finger 6 of the tape 4 has the shape of a trapezoid conjugated with a large base with the outer surface 25 of the tape. The tape 4 is also made with uniformly placed along its length highly elastic elongated protrusions 26 for mating with the teeth 9 sprockets 2 and slots 19 of the pulley 3. Each protrusion 26 is made in the form of a tetrahedral pyramid, the larger base of which is associated with the inner surface 27 of the belt 6. In each finger 6 there is a trapezoidal opening 28, the axis 29 of which is parallel to the outer surface awn
    25 and perpendicular to the longitudinal axis 30 of the tape 4. The bases of the uprights 31 of the fingers 6, formed as a result of opening 28 in it, are located in months, and the bases of the bases of the projections 26 with the tape 4 are mated. The fingers 6 are located with a step Y, and the projections
    26 with step B. The fingers 6 must be of sufficient strength to ensure that they will force the harvest, for example, the corn cobs.
    The transverse rim T of the base of the leading protrusion 26 is smaller than the width S of the tape 4 (Fig. 3). Tape 4 is made of a highly elastic material, for example a mixture of natural rubber and synthetic isoprene. Chloroprene, polyurethane and other materials can also be used. Layers 32 of tape 4, made of lightweight or knitted material, are located at the outer 25 and inner
    27 surfaces to increase tape strength 4.
    The height D of the teeth 9 of the sprocket 2 is significantly greater than the height H of the leading protrusions 26 of the belt 4, which prevents the belt 4 from coming out of the engagement with

    an asterisk 2 as a result of the capture and retention of an agricultural crop and provides an exit for the mus- ipa, which can occur under certain conditions of harvesting, for example, during a laid harvest. The height H of the protrusions 26 is equal to the height of the splines 19 of the pulley 3. When the belt 4 is engaged with the pulley 3, the vertices 33 of the projections 26 mate with the outer cylindrical surface 34 of the pulley 3, and the inner surface 27 of the belt 4 intersects the vertices 35 of the splines 19. The offset of the splines 19 is one relative to the other in the circumferential direction prevents the protrusion of the protrusions 26 between the splines 19, which are not intended to transfer energy from the belt 4 to the pulley 3, but rather serve to guide the belt 4.
    The pitch between the splines 19 in each row of their location is not a multiple of the pitch B of the leading protrusions 26 in order to ensure the mandatory contact of the parts of the pulley 3 with the longitudinal sides of the protrusions 26 even when the belt 4 and the pulley 3 are worn. The splines 19 can be placed alternately m step.
    I The cords 5 of the tape 4 are made of high strength material, such as nylon, polyester, etc., predominantly of fiberglass or
    Iaramida

     Each finger 6 must be pointed (Fig. 1). The trapezoidal shape of the fingers 6 provides sharp edges 36. The asterisk 2 and the pulley 3 are made of high molecular weight polyethylene, which has sufficient strength and rigidity, does not corrode, its low coefficient of friction contributes to the self-cleaning process of the asterisk 2 and the pulley 3. When used This material has an asterisk 2 and a pulley.
    3 is carried out with metal inserts 37 and 38, respectively, arranged concentrically
    Fingers 6 on the working branch of the tape
    4 of one conveyor 1 can be located coaxially with the fingers 6 of the working branch of the belt 4 of another conveyor 1 (FIG. T) or shifted in the direction of movement of the working branches.
    The relative position of the star 2 and the pulley 3 may be different, it is shown in FIG. 1, i.e. Asterisk 2 can be installed on the front (input) end of the transporter 1.
    In the process of operating the feeding device, the belts 4 of both conveyors move at the same speed in the bottom plane. When the belts 4 are moving together, the corn cobs are grasped by the fingers 6 and transported by them over the slot 7 from the forward headers of the conveyors 1 to the rear ones. In the process of moving the cob are separated from the stems, which move down through the slot 7. Thanks; elasticity of the material, from to: expensively made fingers 6, the last from-. They remain free from damage when the device is wedged in and do not cause damage to its other elements. The pointed front edges 36 of the fingers 6 tend to direct the cob, separated from the stems, to the longitudinal axis of symmetry of the feeding device and facilitate the removal of each finger 6 from the cob when the finger begins to rotate around the sprocket 2 at the rear end of the device.
    The proposed implementation of the teeth 9 and jumpers 10 sprockets 2, as well as the fingers 6 of the tape 4 provides a reliable transfer of energy from the sprocket 2 to the tape 4, and also prevents the tape 4 from moving in the direction
    parallel to the axis of rotation 14 of the sprocket 2, and the output of the protrusions 26 from engagement with the teeth 9, since the cavities formed between the teeth 9 are open
    on the one hand, any material that could have accumulated at the base of the cavity 13 is freely removed to the side. The proposed construction of the surface of the base 13, as well as the presence of a rounded surface 15 when the fingers 6 are hooked into the teeth 9 provide for pushing down and out of any debris that can be captured with an asterisk 2.
    The arrangement of the splines 19 of one row and one distance from the other also contributes to the removal of foreign material that the knife is being grabbed by the pulley 3.
