FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to unloading devices used in root-harvesting machines.

The purpose of the invention is to reduce damage to root crops and improve the quality of the device.

FIG. 1 schematically shows a root-harvesting unloading device: the machine at the beginning of loading, side view; in fig. 2 - the same at the end of the download; in: FIG. 3 - the same, top view; in fig. 4 - corrugated wall of the extinguisher, front view; in fig. 5 - swivel on the wall of the quencher.

: The unloading device contains a frame 1, a conveyor 2, an elastic direction, and a casing 3 installed above the unloading iKOHUOM conveyor 2 and in front of it. A frame 4 is fastened to the frame 1, on which the guiding walls 5 of the extinguisher are attached, consisting of several parts 6, articulated: interconnected on the axis 7 and forming a corrugated surface. In the staggered order of the inner surface of the walls 5 and several Rus, gass sh are working consoled elastic elements 8. Each of the elements 8 is fixed pivotally on the axis 7 on the projections of two adjacent corrugations. A cable 9 is fastened to the lower part of the corrugated walls 5, the other end of which is fixed to the drum 10 mounted on the frame 4. Each of the depressions of the corrugated wall 5 is connected to the cable 9 by means of joints and the joints 11. The drive of the drums 10 is hinged kinematic links 12 from the motor 13 mounted on the frame 1 and connected to the hydraulic system of the harvesting machine.

The device works as follows.

At the beginning of the loading of the vehicle by the motor 13 and the kinematic links 12, the drums 10 are conducted in a false manner, the cable 9 is unwound and under the force of gravity the corrugated walls 5 of the damper are lowered to the bottom of the body. In the process of loading, the roots from the conveyor 2 with the cover 3 are directed into the extinguisher channel formed by the walls 5. Freely falling and in contact with their surface with elastic working elements 8 fixed in several layers and staggered, the roots slow down the speed of falling and enter the vehicles without damage. As the body is loaded using the hydraulic motor 13, the kinematic links 12, the drums 10 are driven into rotation by winding the cable 9, and the corrugated walls 5 of the damper rise upwards. The hinge walls of the extinguisher, which are articulated between themselves, form a corrugated surface, are compressed relative to each other, and the hinges 11,

As each wall 5 of the corrugated surface is connected to the wall 5 with the cable 9, the corrugations are compressed in a vertical plane. The reversal of the direction of the reels 10 is performed by changing the direction of the oil supply to the hydraulic motor 13.

Claims (2)

1. An unloading device of a root-harvesting machine, comprising a frame, a conveyor, above the discharge end of which a guide casing connected to the frame is placed, and a speed-reducing device for root crops mounted below the unloading end of the conveyor, carrying guide walls mounted on them several Rus and in a checkerboard order elastic working elements, characterized in that, in order to reduce damage to root crops and improve the quality of the device, each of the extinguisher walls are made of composite and several pieces pivotally connected together and forming a corrugated surface, and is provided with a compression mechanism and stretching this surface, wherein 5, each of the elastic working elements is hinged on two adjacent protrusions of the corrugated surface, which have their vertices turned into the internal zone of the extinguisher. 2. The device according to claim 1, characterized in that the compression and stretching mechanism the corrugated wall surface is made in the form of a flexible element connected at one end with the lower part of this wall and the other with a drum driven by a hydraulic motor; the flexible element is hinged to each of the ridges of the corrugated surface that is not connected with elastic work element. 12 FIG. g five 9 .ten n srig.z 12 C)
