Description

The invention relates to agricultural machinery, in particular to machines for separating soil and plant impurities from root crops.

The purpose of the invention is the reduction of mechanical damage to root crops.

Haha. 1 shows a separator of impurities from root crops, top view; in FIG. 2 - section of spiral winding.

The separator is made of a drum 3 mounted above the conveyor 1 and rotating on the axis 2 with blades 4 forming a spiral winding, inside of which there are fingers 5 pivotally mounted on the axis 6 and rotating together with the drum 2. Axis 6 is installed inside the drum 3 and is offset relative to the axis 2 with the possibility of a constant exit of the fingers 5. A constant exit of the fingers 5 can be achieved by fixing at the ends of the axis 6 of the rollers that run along a special profile of the track fixed on the sidewalls. The minimum thickness of the blade 4 is greater than the diameter of the finger 5.

During the operation of the separator, the cleaned heap, which includes root tubers, plant debris in the form of tops, stolons and weeds, as well as lumps of soil, moves on the conveyor 1 to the drum 3 rotating on the axis 2 with the blades 4 forming spiral winding.

In the area of contact of the heap with spiral winding, root crops, being cleared of soil, are moved by spiral winding along the conveyor 1 to the side. Plant residues in the form of tops, stolons and weeds are captured by the protruding fingers 5, rise and spirals are thrown out. Fingers 5 are completely buried in the opposite zone with respect to the zone where root tubers and plant impurities are located in the blades 4, being cleared of adhering soil and plant impurities. Part of the surface of the fingers. 5 is protected by the cushioning surface of the blade 4 and the fingers 5 are placed in an area where root crops are much smaller.

In the absence of long vegetable impurities in the heap of root crops, the fingers 5 can be completely drowned by regulation so that they do not damage the root crops.

The reduction of mechanical damage to root crops is also achieved by making the fingers 5 from an elastic elastic material, but maintaining its rigidity due to the hard core so that the fingers 5 are not bent when capturing a large number of long plant impurities.

In this device, the collision of root crops with the surface of the blade 4, fingers 5 occurs through the cushioning layers, which reduce damage to the root crops.

Claims (2)

Claim 1. The separator of impurities from root crops, containing a separating conveyor for a pile of root crops, above the working branch of which there is a drum with spiral winding elements that rotate towards the movement of the working branch of the transport, and fingers that extend outside the outer diameter of the drum and are pivotally mounted on an axis, which that, in order to reduce mechanical damage to root crops, the fingers are placed inside the elastic elastic elements of the spiral winding, and the output of the fingers is adjustable. 2. The separator according to claim 1, in that the fingers are made of an elastic elastic material with a rigid core. Figure 2
