Description

The invention relates to agricultural machinery, in particular to devices for separating impurities from root crops used in harvesting machines, for example, fodder and sugar beets.

The purpose of the invention is to increase work efficiency.

Figure 1 schematically shows a device for cleaning and transporting root crops, side view; figure 2 is the same, a top view.

The device for cleaning and transporting root crops contains a feed rod conveyor 1, on the side of which a discharge conveyor 2 with scrapers 3 is placed. Between the receiving part of the discharge conveyor 2 and the end of the side surface of the feed conveyor 1 there is a conveyor element with a drive made of at least three parts in series installed cylindrical rollers 4 and 5. Rollers 4 and 5 are installed on the side of the end part of the working branch of the feed conveyor 1 and against the receiving part of the discharge conveyor 2, p Therefore, the working surfaces of the rollers 4 and 5 and the working branch of the feed conveyor 1 are in the same horizontal plane. The last roller 5, in the process, has transverse grooves in which the scrapers 3 of the outlet conveyor 2 move. One of the rollers 4 and 5 is spring loaded with respect to the other (not shown in Fig.). A screw 6 carrying coils 7 is installed above the working branch of the conveyor 1 and the working surfaces of the rollers 4 and 5 of the conveying element. The screw 6 is installed simultaneously above the working branch of the feeding conveyor 1 and the rollers 4 and 5 perpendicular to them and is located above their working surfaces with the same clearance. Behind the screw 6, towards the similar end of the feed conveyor 1, there is a pair of cylindrical rollers 8 and 9. The lower roll 8 is mounted above the working branch of the feed conveyor 1 also with a gap. The upper roller 9 is located above the lower roller 8. One of the rollers 8 and 9 is spring-loaded with respect to the other (not shown in FIG.). Rollers 4 and rollers 8 and 9 have an opposite direction of rotation, the direction of rotation of the first roller 4 being one-way to the direction of the technological process, and the direction of rotation of the lower roller 8 is opposite to the direction of movement of the working branch of the feed conveyor 1. Identical direction of rotation with respect to the direction of rotation The first roller 4 also has a roller 5. The rotation of the screw 6 is opposite to the direction of movement of the working branch of the conveyor 1.

The operation of the device is as follows.

A heap consisting of root crops with and without associated tops, soil and plant impurities, enters the screw 6 through the working branch of the feeding rod conveyor 1. The turns 7 of the screw 6, interacting with the heap, move it to the side, in the direction of the similar part of the screw 6 and along its axis of rotation. When a heap passes through the gap between the drum of the screw 6 and the working branch of the conveyor 1, the root crops are intensively mixed by turns 7 of the screw 6, they are cleaned of soil and plant impurities adhering to them, and the soil lumps are destroyed, and all loose soil is sifted into the gap between the bars of the conveyor 1 or leaves it together with small plant impurities, passing through the gap between the lower roller 8 and the working branch of the conveyor 1. Root crops, weeds, and also free tops moving along the axis of rotation of the screw 6 which are located between the layers of root crops, also move simultaneously to rollers 8 and 9, undergoing constant pressure from the side of the newly incoming heap. A part of the vorbha, especially one that comes under a similar part of the screw b along the lateral surface of the working branch of the conveyor 1, does not reach the rollers 8 and 9 due to its small axial path. Moving along the screw 6 and turns 7 of the screw 6 moves to the rollers 4 of the conveying element. As the components of the heap move towards rollers 8 and 9 and rollers 4 and due to the fact that the rollers 8 and 9 and rollers 4 rotate counterclockwise, vegetable impurities and associated tops of root crops are drawn between the surfaces of rollers 8 and 9 and rollers 4. Passing between them, impurities are carried outside the sweeper; The associated root crops, under the double influence of the pulling forces from the side of the rollers 8 and 9 and the rollers 4, and the axial movement of the root crops from the side of the turns 7 of the screw 6, are removed from the heads of the root crops and, like other impurities, goes outside the machine. The cleaned root crops by turns 7 of the screw 6 are moved to the roller 9, where they are picked up by scrapers 3 of the outlet conveyor 2 and fed further.
