(54) MECHANISM FOR TREATMENT MACHINE FOR REDUCING AND REMOVING

THEIR BATTLES

   ,one

The invention relates to agricultural machinery, in particular to machines for harvesting root crops.

A known mechanism for a machine for harvesting root crops, comprising a top-lifting section with a screw cutting apparatus, having a conical intake part and interacting with a resetter, a counter plate and a drive 1.

Odiako such a device has a high energy consumption and has low technical and economic indicators.

The closest in technical essence and the achieved result to the proposed mechanism is to a topping machine for leveling the root crops and removing their tops "containing two counter-rotating shneke, (each of which is set obliquely to the horizontal and to the direction of movement of the crank conveyors and has a portion of conical forms 2.

However, this device in the process of work greatly injures the roots.

The purpose of the invention is to reduce damage to root crops.,

The goal is achieved by the fact that in the mechanism to the topping machine for leveling the root crops and removing their tops, containing two counter-rotating augers, each of which is set obliquely to the horizontal and to the direction of movement of the towing conveyors and has a conical shaped intake part, the apex of the conical parts of the auger are placed directly behind the trailing traispor, ter, and the angle of inclination of the auger axis to the horizontal op | eaten from the ratio

li-arctg-j, where is the step of winding up the scroll;

r-radius of the intake part of the auger in the zone of contiguity of the augers.

In addition, the winding of the auger in its intake part is made pointed.

FIG. 1 shows the device, a general view; on fng. 2 - the same, top view; in fig. 3 - auger cutting apparatus, top view.

Claims (2)

The mechanism for the topping machine for leveling the root crops and removing their tops contains a rigidly attached to the frame 1 undermining paw 2, to the lifting of 3 topping section 4 with a screw-cutting device 5 having a conical intake part 6 and interacting with a drop blade 8 and a contouring insert 8 and 9. The conical intake part of the cutting unit is aligned with the topping section, i.e. it is located directly behind it, with the axis of the cutting unit being inclined at an angle to the horizontal, the value of which is determined by nnym sootnoscheniem, wherein the blade schneka a chamfer sections are tapered. This layout of nodes provides a reduction in energy consumption for the process and damage to harvested root crops. The device works as follows. When the mashine moves, the undermining paw 2 acts on the root-bearing layer of soil, the tops 3 raise the tops of the root crops up and form it into tight bunches to make it easier for them to pick up the belts of the lifting section 4 and then move the harvested crop to the area of the cutting apparatus 5. Botva The screw blades of the counter-rotating screws are drawn into the gaps between them, while the roots are pulled up to the tops of the tops, aligned and fed to trim the tops adjacent to the screws rotating plate8. The trimmed tops of root crops are thrown out by the belts of the topping section 4, by the blades of the paratroop shnekovyhs 5, by the dumpers 7, the mutual position and direction of rotation of which ensures a reliable ejection of the entire cut mass beyond the mashina. Next, the roots get into the vehicle .. The use of this device reduces the energy intensity of the process and improves its technical and economic indicators, while the productivity of labor increases by 19-21%. Claim 1. Mechanism for a topping-off machine for leveling root crops and removing their tops, containing two counter-rotating jaws, each of which is set obliquely to the horizontal and to the direction of movement of the towing conveyors and has an intake part of a conical shape, characterized in that In order to reduce damage to root crops, the apex of the conical part of the screw is placed directly behind the topping conveyor. Moreover, the angle of inclination of the auger axis to the horizontal is determined from the relation where t is the step of winding the screw and; g -7- radius of the intake part of the auger in the zone of contact of the augers. 2, the Mechanism according to claim 1, characterized in that the winding of the auger in its intake part is made pointed.
