    Harvested crop material is fed to the cylindrical cutter-head of a forage harvester by a feeding assembly consisting of opposed pairs of upper and lower feed rolls. The articulated upper roll assembly floats to accommodate variations in the flow of crop material. The downstream upper feed roll is carried on a pair of opposite radius arms which are rigidly coupled by a transverse leveler shaft, providing a stable frame and minimizing cocking or twisting of the roll. A second pair of feed roll arms is pivotally connected to the radius arms and extends forward to support the upstream feed roll which is journaled on a shaft rigidly connected between the feed roll arms. A stop and biasing arrangement provides that each upper roll may float independently, the articulation of the feed roll assembly being such that upward movement of either roll or the rolls together is subject to the restoring force of a tension spring. However, upward movement of the upstream roll in relation to the downstream roll is restricted by a stop which limits rotational movement between the feed roll arms and the radius arms supporting the rolls.

    The invention relates to agricultural machinery, primarily to forage harvesters and, in particular, to devices for supplying agricultural crops to a grinding apparatus. Forage harvesters are known for harvesting crops from the field, reducing its size or shredding and feeding it to a barn or other receiver. In conventional combines, the feeder directs the harvested crop from the harvesting unit to the drum grinding machine, with the axes of the feed drums or rotating conveyor elements parallel to the axis of the grinding machine, and the crop is fed into the machine mainly in the radial direction. The grinding apparatus and its feeding system are located mainly between parallel vertical side walls and usually the feeding system consists of two transporters located opposite each other, one of which (usually this is LOWER) is fixed to the grinding apparatus, while the other can float to increase the loading opening in order to adapt to changes in the crop flow, but at the same time it is kept by the elastic means 1. The disadvantage of this device A is its difficulty in moving in response to the transport of varying flow rates and mat thickness from the crop. A harvester is also known, which includes a header, a chopping drum with a shearing plate and a sealing device placed between the side walls of the chamber and consisting of front and rear upper and lower drums, of which the upper drums are mounted on spring-loaded arms and transverse shafts 2. A disadvantage of the known device is the complexity of its design. The purpose of the invention is to simplify the design. The goal is achieved by including a header, a chopping drum with a shearing plate and a sealing device located between the side walls of the chamber and alternating from the front and rear upper and lower drums, from which the upper drums are mounted on spring-loaded hilchagas and transverse shafts, a guide cover is installed above the rear upper drum, and the transverse shafts of the upper drums are rigidly connected with the levers to form two U-shaped frames, with the U-shaped levers the frames of the front upper drum are pivotally connected to the shaft of the rear upper drum, and the levers of the U-shaped frame of the latter are pivotally connected to the side walls of the chamber. 1 shows a forage harvester, side view; in Fig.2, the front parts of the feeding unit and the grinding apparatus of the combine, side view; in FIG. 3, section A-A in FIG. 2 (wherein the protective cover mounted on the transverse shaft of the crank is removed); figure 4 - section bb in figure 2 (hinged connection between the front and rear feed drums); figure 5 - section bb In fig.Z (protective cover mounted on the crank shaft). The harvester (FIG. 1) contains the main frame 1 mounted on two wheels 2. The front harvesting unit 3, such as a corn header, directs the harvested crop to the feeding and grinding unit 4, from which the culture is fed to the transverse auger conveyor 5 and from it under the action of the fan b is removed through the exhaust pipe 7. The crop to be unloaded can be collected in a trailer (not shown), which is attached to the hitch 8 on the combine. The combine is transported using an appropriate tractor, which is connected to the drawbar 9 and the drive shaft 10. Power is transferred from the drive shaft to the silo harvester units through an appropriate gear mechanism (not shown). Figure 2 shows in more detail the feeding and grinding unit 4, which contains two, e basically the same, left and right side walls 11, located opposite each other in a vertical position, between which the elements of the feeding and grinding unit are placed. The side walls 11 are suitably reinforced and placed on the frame 1 of the combine using subframes (not shown). In the side wall 11, there is a cylindrical mounting hole 12, a hinge device 13, an arcuate slot 14 centered on the hinge device 13, and a large irregular slot 15. The brackets 16 and 17 are mounted for limit stops and attached respectively to the outside of each side wall 11, each bracket 16 is located between the slots 14 and 15, and the bracket 17 neocodits approximately in the center under the slot 15. A cup 18 in which there is a pillow is rigidly attached to each bracket from above. 19 and made of a material with maloy.uprugostyu, for example, hard rubber, which extends over the edge of the cup 18. Adjacent the upper and lower front corners of the side walls 11 are fixed support arms 20 and 21 of the cleaning unit, respectively upper and lower. .
    Between the lower rear parts of the rock walls 11, a grinding device 22 of conventional type is installed with the possibility of agglomeration and contains a drum grinding device 23, on the periphery of which a large number of spiral knives are located and which works in a known manner in combination with a fixed counter plate 24. The grinding agretat 4 also has the casing 25, which covers the upper periphery of the chopping drum.
    A feed conveyor 26, located between the side walls 11 and immediately in front of the chopping device 22, consists of a floating spring-loaded upper conveyor 27 and a fixed lower conveyor 28 directly below it, including a front lower feed drum 29 and a smaller rear; The research institutes of the lower pitch drum 30 installed next to the shear plate 24. The surfaces of the feed drums are processed in the usual manner. The upper conveyor 27 is hinged and consists of a rear and front feed nodes. The U-shaped frame 31 consists of two radial levers 32 arranged opposite each other, located along the outer surfaces of the side walls 11, the transverse shaft 33 and the outer upper feed drum 34 fixed rigidly on it, which is located transversely between the side stents 11, -given frame rear upper feed barabaia. In addition, the U-shaped frame 31 has a transverse hexagonal shaft 35 and a guide casing 36. At the end of each radial lever 32 there is an opening 37 for the hinge device 13 and a larger opening 38 for accommodating the hinge bearing 39 () On the front side of each radial arm 32, there is a release clip 40 provided with a transverse bore 41 having a hexagonal shape in cross section that encloses two lugs 42 with a corresponding 5 lock 43 for tightening the clamp.
    The hex hole 41 is preferably drawn to fit the size, so that the hex shaft 35 is easily assembled, but is strong
    10 fixing occurs after tightening the clamp. Several ahead of the axis of the hole 38 of the radial lever 32 is located the locking boss 44 (Fig. 2), projecting from the outer
    5 of the radial arm 32 and the actually proceeding downward continuation of zgikim 40, which itself is directed transversely outward from the outer side of each radial lever 32. The lever 45 is adjusted by the front extension of the radial lever 32 and the adjustment screw located on it 46.
    The guide casing 36 contains a main rigid arcuate portion 47, partially covering the rear upper feed drum 34, which is located across between the side walls 11 circumferentially on the front side of the upper feeding drum 34 and lowers down approximately to the level of the drum axis. The portion 47 is attached to the hex shaft 35 with an appropriate zipper
    5 of the device 48. In addition, the direction of the cover 36 includes a flexible flap 49 attached to the hex shaft 35 by a clamping device 48 and a holder 50, which is laterally arranged so that, with its ends, sliding contact with the inside surfaces of the side walls 11, and also back closely with a case element. The bending of the valve 5 1 ka 49 is in contact with the casing 25. The U-shaped frame 51 comprises left and right 52 and 53 extending parallel to the outer side of the side walls 11, between which the front upper drum 54 is rotatably supported, and is a U-shaped frame of the front upper feed drum. As shown in figure 4, at the rear end of the right lever 63
    5 there is a part in the form of a hub 55, which comprises a protrusion 56 rotating in a hinge support 39 of the radial ixnara 32, and a concentric hole 57 located outwardly from
    0 of the protrusion 56, in which the anti-friction bearing 58 is placed, in which the shaft 33 of the rear upper feed drum 34 rotates. The front part of the lever 53 is also made in the form of a hub 59, which is drilled and bored to receive the shaft of the rear upper feed drum, which is firmly fixed in the right lever 53 by means of the pin 60. Sidewise and outward from the right lever 53, approximately in the middle between the rear and front hubs 55 and 59, the boss 61 protrudes under the tension spring. The tab 62 protrudes forward from the front hub 59. The front upper feed drum 54 has, between the lateral walls 1 11, sub-spindle sleeves 63 f rigidly attached at their ends with the side walls 11 and protruding through them to the outside. A bearing 64 is placed in {of each of the sleeves 63, with which the drum unit 53 rotates on a stationary shaft. At the outer end of the left sleeve 63, the driver H-pin 65 is rigidly fixed. The left lever 52 is basically the same as the right lever 53, including that it is rigidly connected to the end, but it has a bend 66 so as to provide a place for the chain pin; . water from the front feed drum 54, as well as to the reel 67 for mounting the tensioning element for the chain. Two tension springs 68, each of which with one end is attached to the bob 61 of the levers 52 and 53, respectively, and its other end is attached to the ram elements (not shown), displace the upper transport unit down to the lower lower conveyor 28. Inlet to feed bars The conventional way is carried out using a universal joint and a sprocket 69, rigidly fixed on the left end of the transverse shaft 33 and connected to the extender 70 of the gear mechanism of the combine. Thus, the rear feed drum 34 is driven directly, while the power to the front feed drums 54 is transmitted through sprockets 69 and 65 using a conventional chain transmission 71. In the usual silo harvesting, the rotation direction of the back drums 30,29,34 and 54 will be as shown in FIG. 2, but there are conventional means (not shown) connected with extension 70 for selectively reversing the direction of rotation of the drums. Silage harvester works as follows. When moving across the field with a spruce with a commercial crop, the harvesting unit 3 feeds the crop into the gap between the upper and lower front feed drums 54 and 29, from which the culture is directed down between the upper and lower conveyors 27 and 28, respectively. As shown in FIG. 2, the upper surfaces of the stationary lower drums 29 and 30 and the counter plate 24 are approximately in one line and form a conveying surface for feeding material almost radially into the drum grinding device 23. The upper conveyor 27 is shown in a closed stationary position, as if the material had not been transported, and the front sub-drum drum 54 is effectively blocked as a result of the interaction of the levers 52 and 53 with the front stop pads 19 on the brackets 17, the rear upper feed drum 34 is blocked as a result of the interaction of the adjusting screw 46 with the rear cushions 19 on the brackets 16. During the passage of the crop, both drums will float, lifting iodine from their stops by the action of the crop mat, while the upper conveyor 27 works as one unit, The U-frame 31 is rotated on the hinge device 13, while the articulation of the shaft of the rear upper drum with the levers of the U-shaped frame of the front upper drum located between the rear and front ne of the supply rolls 34 and 54, respectively, formed by anti-friction bearings, allows the front of the grinding unit 4 to find its own level. As shown in FIG. 2, the line of action of the spring 68 extends approximately perpendicularly and in the middle of the line connecting the centers of the rear and front upper feed drums 34 and 54, respectively, within the thickness range of the transported mat from the culture, with the result that each of the drums applies approximately the same pressure | and almost equally reacts (under the influence of the compression of spring 68) to the general longitudinal changes in the thickness of the mat from the crop. The adjusting screw 46 serves to set the minimum clearance between the rear feed drums 34 and 30 in accordance with the specific operating conditions. During this adjustment, the rear end of the levers 52 and 53 (rear hub) is raised or lowered; however, the front upper feed drum 54 immediately stops under its axis, with the result that the rear stop adjustment only causes the arms 52 and 53 to swing on their stoppers 19, therefore, the effect of the adjustment on the gap between the front feed drums is negligible. In any unusual situation, in an E-vernier turn: the feed drum 34 deviates too strongly upward relative to the front upper feed drum 54, effectively moving the levers 53 and 52 back, if required, the foot 62 of the levers maintains contact between the feed drum levers and the rear locking cushion.
    Although the top feed drums can move upward independently to adapt to uneven material flow, it is desirable that the back drums 30 and 34 be prepared to receive an unusually thick mat transported back by the front drums 29 and 54. This can happen, for example, when the drums are reversed to eliminate the blockage and the cut end of the mat enters between the feed drums and then the mat can present an end surface that is too far out to be taken back ie supply rolls. This problem has been eliminated due to the presence of a locking bolt 44, which guarantees that any increase in the loading opening between the front drums 54 and 29 above the set minimum value (for example, 19.05 mm is the most effective value) is immediately accompanied by a corresponding increase in opening between aspassed by the locking lug 44 with the upper surfaces of the levers 52 and 53. With this ae and the action, the further rotation of the levers 52 and 53 relates to ialnyh arm 32 is prevented and the upper conveyor 27 is rotated upwardly as one unit around the hinge 13, whereby the gap between the rear feed drums 34 and 30 is increased in order to ensure reception ,, the new thread material. Then the upper conveyor can be bent, the levers 52 and 53 swing as if adjusting to the longitudinal changes in the thickness of the mat, always limiting m / so that if the front feed roll becomes differentially much larger than pa: cKpijr the rear feed drum in this moment, This boss 44 is actuated to adjust the height of the rear feed drum.
    Consecutive connection of two U-shaped frames of the rear and front upper feed drums, respectively, allows to get the Hinged upper conveyor 27, which has greater resistance or resistance to the drum skew or transverse spacing due to the transverse unevenness of the thickness of the transported mat. In the front of the chopping unit 4, the connection between the levers 52 and 53 and the stationary shaft, resistant to torsion, stiffens it to withstand the action of the stitching force acting on the front drum 54 and transfers it through the hinge 55 to the U-shaped frame 31, represented by the rear feed drum assembly. In the latter, the rigidity of the crayfish is due to the strong connection, which is not round in cross-section, between the strong transverse scarlet 35 and the radial arms 32, which also resists to a hingeing force applied to the rear feed drum 34. Thus, in such a consistent (tandem ) Both subframe structures must be rigid to avoid skewing the front drum.
    It is inevitable that some of the material will not immediately fall into the screw conveyor 5, but will be carried away by the grinding device 23 inside the cylindrical body, including the housing 25. The latter must end at a considerable distance from the counter-plate 24 in order to leave space for movement upwards and rear feed drum 34 and feeding crop to chopping device 23. Consequently, part of the carried crop is fed to the rear podgyode drum 34, in this place retracts them up and forward. However, this material is in a protective casing 36, which moves with the drum 34 and guides the material back down to the mat between the upper drums. The elastic of the zasloika, its ends tightly pressed against the side walls 11, and its rear edge remains close to the outer surface of the casing 25 even when the upper conveyor is moving, serves as a seal to reduce material loss, especially when it is dry, when the valve The action of the drum can lead to a wide variation of the material through the gap above the rear feed drum 34.
    Thus, the invention will allow to simplify the design of the silage combine harvester. 11 5 36 yi ji g Z1 It, 1/3 57 7J
