Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to devices for separating root crops from impurities. The purpose of the invention is to increase the degree of cleaning of the roots. A device for cleaning root crops contains devices for loading 1 and unloading 2, a cylindrical casing 3 with a grate 4 in the lower part, transverse finger drums 5,6 and longitudinal drums 9 rotating auger 10 driven 11. Roots getting through the device 1 into the casing 3 moved by screw 10 to the exit. In the process of moving, they are treated with cleaning elements-drums 5, 6, 9. In this case, the impurities are removed through lattice 4. 2 H. p. f-ly, 3 ill.

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to devices for separating root crops from impurities.

The purpose of the invention is to increase the degree of cleaning of the roots.

FIG. Figure 1 shows schematically a device for cleaning root crops; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one.

bans and move in waves, then pada, then lift up.

A part of the root-and-vegetable crops, falling on the side surface of the casing 3, is subjected to intensive influence from the side of the 9 longitudinal combing finger drums.

After intensive separation in the zone of cleaning elements, the soil remains through the lattice part 4 of the casing 3

A device for cleaning the root crop 10 and the output, the fruit contains a device 1 for the Intensification of technological loading and unloading of 2 cleaned root crops, a cylindrical casing 3 with

fixed to its lower lattice

The process of improving the quality of cleaning root crops from soil in the proposed device is achieved by completeness

4 parts transverse finger bar- 15 use transverse drums 5

bans of greater than 5 and smaller than 6 diameters, the height of the fingers of which alternates in pairs in length with an increase of 7 or with a decrease of 8 from the middle of the adjacent drums. On the surface of the casing 3 there are also fixed longitudinal 9 elastic combing-20 augers. Finger drums, and inside it there is a rotating screw 10, the rotational movement of which is carried out by the actuator 11, which also serves for smaller and smaller 6 diameters, which make it possible to cover the entire surface of the roots to be cleaned. In addition, the number of revolutions of the cleaning elements is twice the number of revolutions.

Claims (3)

1. A device for cleaning the root-and-water of longitudinal elastic combing fruits from impurities, containing sub-finger drums 9. Rotation of the transverse elastic finger drums is performed using another known drive (not shown). for loading and unloading, a cylindrical housing with cleaning elements fixed on its surface and a rotating auger placed inside it, characterized in that A device for cleaning root crops 30 in order to increase the degree of cleaning of root and tuber crops, it is provided with transverse installation screws at the bottom of the screw, all the cleaning elements being in the form of drive fruit from impurities works as follows. finger drums on their During operation of the screw 10 and the drums 5, 6 and 9, the roots and tubers to be cleaned are fed into the fixture 1. The root is 35 surfaces, and the height of the fingers of one tuber, falling into the spin rotation zone, is made from the transverse drums with a decrease of 10 in the casing 3. In the process of moving the root crops by the screw 10, the soil and impurities are preliminary separated from them. Further, 4Q in the zone of cleaning elements 5, 6, 9 root crops are subjected to intense mutual influence, due to the rotation of the transverse 5 and 6 finger drums, where the root crops move from the middle to the edge adjacent to this drum — with a decrease in the height of the fingers. 2. A device according to claim 1, characterized in that the transverse drums have different diameters. 3. The device according to claim 1, characterized in that the gear ratio between the drive rotation of drum drums and auger equal to each greater 5 for a smaller 6 bar- 45 but two. bans and move in waves, then pada, then lift up. A part of the root-and-vegetable crops, falling on the side surface of the casing 3, is subjected to intensive influence from the side of the 9 longitudinal combing finger drums. After intensive separation in the zone of cleaning elements, the soil remains through the lattice part 4 of the casing 3 and output, Intensification of the technological process and improvement of the quality of cleaning of the root crops from the soil in the proposed device is achieved by completeness use transverse drums 5 use transverse drums 5 auger. larger and smaller than 6 diameters, allowing to cover the entire surface of the root and tuber crops to be cleaned. In addition, the number of revolutions of the cleaning elements is twice the number of revolutions. Invention Formula finger drums on their surface, and the height of the fingers of one of the transverse drums is made with a decrease from the middle to the edge adjacent to this drum with a decrease in the height of the fingers. 2. A device according to claim 1, characterized in that the transverse drums have different diameters. 3. The device according to claim 1, characterized in that the gear ratio between the drive ten FIG. 2
