Description

The invention relates to agricultural machinery, in particular, devices for separating impurities from root crops used in harvesting machines, such as fodder and sugar beet,

The purpose of the invention is the reduction of vegetable impurities in the heap of root crops.

FIG. 1 shows schematically a device for cleaning and transporting root crops, side view; in fig. 2 - the same, top view; in fig. 3 - the same, front view; in fig. 4 - a method (its variant) of adjusting the angle of inclination and its fixation.

The device contains a feed bar conveyor 1, above the working branch of which a rod 2 is installed, carrying coils 3. Screw 2 is located above the working branch of the feeding conveyor 1 with a gap. Behind the screw 2, in the direction of the similar end of the feeding conveyor 1, a pair of cylindrical rollers 4 and 5 is opposed. The lower end 4 is installed above the working branch of the feeding conveyor 1 also with a gap. The upper drum 5 is located above the lower roller 4. One of the rollers 4 and 5 is spring-loaded with respect to the other. Rollers 4 and 5 have an opposite direction of rotation, and the rotation of the lower roller 4 is opposite to the direction of movement of the working branch of the feeding conveyor 1. The identical direction of rotation with respect to the direction of movement of the working branch of the feeding conveyor also has a screw 2. Against the discharge zone of the screw 2, on the side of the feeding conveyor 1 , a transporting elevator 6 is installed, carrying scrapers 7. Between the receiving part of the transporting elevator 6 and the end of the side surface of the feeding conveyor 1 there is a comb 8 having a pa The fingers 9. The fingers 9 are made flexible and attached to the base 10, which by means of a spline joint 11 is fixed to the brackets 12, which are fastened to the frame (not shown).

The method for making the rotator 8 can also be different, for example, by installing between the ends of the base 10 and the brackets 12 friction clutches or the like.

A device for cleaning and transporting the root crops is as follows.

Before starting, set the angle and the inclination of the fingers 9 of the comb 8 relative to the plane that passes through the working branch of the feeding conveyor 1. The angle “is set by turning the brackets 12 in the splined joint 11 and choose it according to the size of the root crops and the litter box. A pile of root vegetables

associated with and without the tops, soil and vegetable impurities, along the working branch of the feeding conveyor 1 goes to the screw 2. The turns 3 of the screw 2, interact with the fruit feeds. move them to the side, in the H direction of the axis of rotation of the screw 2. When they pass through the gap between the screw of the screw 2 and the working branch of the feeding conveyor 1, the roots are intensively mixed by turns 3 of the screw 2, clearing

soil and plant contaminants adhere to them, and soil lumps are destroyed and all loose soil is either sifted or comes off from transperstoro 1 together with small plant impurities, passing through the gap between the lower drum 4 and the working branch of the feeding conveyor 1. Root crops without stalks . The tops and associated tops on them, as well as weeds and free tops, which are located between the layers of the roots, move the coils 3 of the screw 2 along the axis of rotation of the screw 2 and to the rollers 4 and 5, experiencing constant backing from the side New incoming heap. As

advances of these components and due to the fact that rollers 4 and 5 rotate counter, the plant impurities between the surfaces of rollers 4 and 5 are sucked in. The passage between rollers 4 and 5, impurities enter the similar part of transferring portions 1 and is carried out by them beyond the limits of the harvesting machine. The root of the root crops topped by, having experienced the double effect of the retraction effort from the rollers 4 and 5

and the axial movement of the roots from the side of the turns 3 of the screw 2 is removed and, similarly to the rest of the impurities, is conveyed by the feeding conveyor 1.

Vegetable impurities coming

on the side surface of the working branch of the transporting conveyor 1 under a similar part of the screw 2, the comb 8 installed at an angle is held at the displacement of the root crops by the turns 3 of the screw 2 and is carried out

conveyor 1 outside the machine. The amount of impurities released from the pile is controlled by changing the angle o. by turning the comb 8 in the spline connection 11.

Purified root crops, having a constant backwater from the side of the incoming ones, bend the pzg 9 of the comb B and move to the transport elevator 6, the scrapers 7 of which are fed further.

Claims (1)

Claims 1. A device for cleaning and transporting root crops, comprising a feed conveyor, a scraper outlet transport means a rotary comb mounted between them on an axis, between the teeth of which are placed scrapers of a discharge tracer, characterized in that in order to reduce plant matter in the heap of root crops, the comb axis is parallel to the working branch of the feeding conveyor in the same plane with it, while the comb is mounted on an axis with the ability to adjust and fix the angle of inclination, and its fingers are elastic. 2, the apparatus according to claim 1, characterized in that the comb is connected to the shaft by means of a spline joint. 4 - t 1 d fig. 2 ; ShZH Yu eleven fig L
