FIG. R

The invention relates to agricultural machinery and can be used in the construction of grain harvesting machines.

The purpose of the invention is to improve the quality of the cutting of the ground by the header and decrease the pressure on the Vedush bridge, their wheels in the working and transport positions of the combine.

FIG. 1 schematically depicts a supply distributor 17, separating the pipeline 18 with the hydraulic system of the combine. Thus, the internal cavities of the hydraulic cylinders 5 and 12 are communicated only between themselves and in them, under the action of the mass of the harvester and the accelerations it receives during the movement of the combine, approximately the same pressure of the working fluid is established.

When moving the combine on uneven

rotary in hinge 14 relative to cutter body 9 down, plungers

In this case, the plungers of the hydraulic cylinders 5 are driven under the pressure of the mass of the header, it generally

The wheels 10 on the projection or lifting of the soil. The movement of the plungers of the hydraulic cylinders 5 and 12 and other elements of the hitch mechanism and the header, as well as the working fluid, occurs in reverse order, and the header itself rises up. Thus, approximate copying by the header of the nature of the soil microrelief change is carried out directly during the movement of the komgaemy hinge mechanism in the working polo-10 surface of the field with the header in the working position, side view; in fig. 2 the same, in life when the wheels 10 are driven in the void or the transport position of the header; in fig. 3 - under the slope they, together with the lever 11, are the same when moving obstacles by the combine in the working position of the header; in fig. 4 - the same when moving obstacles combine in. hydraulic cylinders 5 are advanced, the working transport position of the header. The liquid from the internal cavities of the hydraulic mechanism of the header of the header consists of the cylinders 5 is displaced and flows through the clone chamber 1, the hinges 2 of which are the pipeline 19 to the hydraulic cylinder 12. When fastened with clamps 3 to the body 4 threshers , and plunger hydraulic cylinders 5. The latter, through hinges 6 and 7, connect 20 to be lowered, turning together with the brackets of the axle of the driving wheels 8 with the inclined chamber 1 in the hinge 2. With the inclined cam 1. Between the driving wheels 8 and Corps 9 Ms ki are additional wheel 10 with pivoting levers II. The latter have plunger hydraulic cylinders 12, which are connected through the hinges 13, 14, 15 and 16 to each other and to the body 9 of the header. The hydraulic cylinders 5 of the inclined chamber 1 are interconnected and the hydraulic distributor 17 of the combine pipe 18. The hydraulic cylinders 12 arms 11 of the link. interconnected and with the pipeline When the combine with uneven hearth 18 moves with the help of pipeline 19. Thus, the surfaces of the floor or the road with the header in the image, the internal cavities of the hydraulic cylinder-transport position when driving the wheels 10, 5 and 12 communicate through a pipe ledge or lifting the soil together with the water 18 and 19 between themselves and can with the coil lever 11 rotate in the hinge 14 through the hydraulic distributor 17 with the hydraulic or relative to the header 9 of the header upwards, the plunger system (not shown) of the combine. The hydraulic cylinders 12 are pushed in, the mechanism on weights harvester works as follows.

When transferring the header to the transport position, the combiner using the hydraulic distributor 17 directs the flow of the 40 burners of all hydraulic cylinders 5 and 12 of the hydraulic pump of the combine's hydraulic system, turning together with the inclined pipelines 18 and 19 into the internal chamber 1 around the hinge 2. When the bridges of the cylinders 5 and 12 run over. Under the pressure of the wheels 10 on the trough or under the slope of the working fluid road, the plungers of the hydraulic cylinder move the plungers of the hydraulic cylinders 5 and 12, the ditch 5 and 12 move forward and turn. and other elements of the hinge mechanism and the inclined chamber I in the hinge 2 up, and the header and the working fluid, the lever 11 with the wheel 10 in the hinge 14 down, raise the housing 9 of the header. To transfer the header to the working position, the combiner, using the hydraulic distributor 17, directs the flow of working fluid from the inside JQ to the relief directly during the moving cavities of the hydraulic cylinders 5 and 12 to the drain. combine harvester. Under pressure mass header on the plungers

of these hydraulic cylinders, the working fluid you-As in the working position, and at

tightly drained, the plungers are moved, the transport position of the header is additionally and the inclined chamber 1 is turned downwards into the body wheel support and its response R corresponding to the hinge 2, and the lever 11 with the wheel 10 in 55 decisively decreases the pressure Q at the front hinge 14 up, lowers the body 9 header. When reaching the working or transport position, as well as other positions of the header, close to them, the combiner includes

Close the working fluid through conduit 19 into the internal cavities of the hydraulic cylinders 5. The rams of the latter are advanced and the header under the action. The wheels 10 and the pressure plunger in the reverse order, and the header itself is lowered, following the microrelief of the soil or road. As in the working position, the wheel travel of the header is approximately the copying of the drive wheels 8 and loads the rear control wheels (not shown) of the combine, making it unnecessary to counterbalance the header on the threshing machine. The magnitude of the reaction K, as well as

hydraulic valve 17, separating the pipeline 18 with the hydraulic system of the combine. Thus, the internal cavities of the hydraulic cylinders 5 and 12 are communicated only between themselves and in them, under the action of the mass of the harvester and the accelerations it receives during the movement of the combine, approximately the same pressure of the working fluid is established.

When moving the combine on uneven

rotary in hinge 14 relative to cutter body 9 down, plungers

the surface of the floor with the header in the working position when driving the wheels 10 in the depression or downhill, they, together with the lever 11 of the hydraulic cylinders 5, extend, the working fluid from the internal cavities hydroelectric plungers of the hydraulic cylinders 5 are drawn in under the pressure of the mass of the header, it generally

cylinders 5 is pushed out and flows through conduit 19 into hydraulic cylinder 12. When it is lowered, it rotates together with inclined chamber 1 in hinge 2. When tightened. When the combine moves with uneven ground wheels 10 on the protrusion or soil lifting, the plungers of the hydraulic cylinders 5 and 12 and other elements of the attachment mechanism and the header, as well as the working fluid, move in the reverse order, and the header itself rises up. Thus, approximate copying by the header of the nature of the soil microrelief changes is made directly during the movement of the cylinders 5, it is forced out and flows through the pipeline 19 into the hydraulic cylinder 12. When it is lowered, it rotates together with the inclined chamber 1 in the hinge 2. When it is pulled. When the combine moves from the uneven surface of the floor or the road with the header in the transport position when the wheels 10 are driven to the ledge or the soil is raised, they, together with the lever 11, turn in the hinge 14 relative to the header body 9 upward, the plungers of the hydraulic cylinders 12 are pushed back 12 is raised, turning together with the inclined chamber 1 around the hinge 2. When the wheels 10 are driven over the trough or under the slope of the road, the plungers of the hydraulic cylinders 5 and 12 and other elements of the hitch mechanism and the working fluid Ruet relief directly during the movement of the combine.

Close the working fluid through conduit 19 into the inner cavities of the hydraulic cylinders 5. The rams of the latter are extended and the header under the action of the wheel 10 and the pressure of the plungers of all the hydraulic cylinders 5 and 12 is raised, turning with the inclined chamber 1 around the hinge 2. When the wheels 10 arrive On the trough or under the slope of the road, the movements of the plungers of the hydraulic cylinders 5 and 12 and other elements of the linkage and the header, as well as the working fluid, take place directly during the movement of the combine.

go in reverse order, and the header itself goes down, following the microrelief of the soil or road. As in the working position, the wheel travel of the header, approximately to the transport position of the header, is an additional wheel support and its response R accordingly decreases the pressure Q on the front

drive wheels 8 and reloads the rear control wheels (not shown) of the combine, making counterweights on the thresher unnecessary. The magnitude of the reaction K, as well as

Some kinematic parameters of copying the topography of the floor or the road by the linkage can be changed by selecting the kinematic parameters of both weights and the ratio of the total areas of the plungers of the hydraulic cylinders 5 and 12.

Since the supporting wheels of the harvester perceive only part of the mass of the harvester, this allows them to be made of relatively small diameter and be placed between the harvester body and the thresher body next to the main drive wheels.
