Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to manure types for post-harvest processing of root and vegetable crops.

The purpose of the invention is to reduce the number of root crops at the time of increasing the productivity of the device.

FIG. I presents a diagram of the proposed device, side view; in fig. 2 - the same, end view; on phpg. 3 - node I on fpg. one; in fig. 4 — node II in FIG. one.

A device for dry cleaning of root and field crops contains a frame formed by struts 1, junction bars 2 and straps 3, drive 4, a drum made in the form of a cone, with its small base facing the loading tray 5. The conical drum of the device is movably mounted on support rollers 6 , each of which is mounted with the possibility of rotation around the transverse axis 7 of the levers 8.

Each of the two diametrically mounted support rollers 6 is installed against the corresponding annular section 9 of the conical drum of the device. The conical drum is made in the form of annular sections 9. Each of the annular sections 9 of the conical drum is provided with an individual drive that provides each of the annular sections 9 of the conical drum with oppositely directed movement. The ring sections 9 are aligned with respect to each other with a gap of 10 to 15 mm. The inner base of the rim of each of the annular sections 9 is provided with an elastic finger working surface (not shown), made, for example, of elastic rubber. In the opening between the vertical posts 1 is fixedly mounted on the bottom of the device, directly under the conical drum, the noddon 10.

A device for dry cleaning of tubers contains a discharge tray 11 mounted on the opposite side relative to the loading tray 5. The individual drive 4 for providing the annular sections 9 of opposite directional movement is made in the form of two rotating in opposite directions of the drive 12 and the driven 13 central shafts, which are parallel are located in relation to each other and are installed in the upper part immediately above the conical drum of the device. Drive 12 and drive 13 are the central shafts of the individual drive 4 kinematically connected by drive 14 and driven 15 P1-core.

The shafts 12 and 13 were spun with cylindrical rollers 16 with an annular groove 17 and an asterisk 18. The teeth of the sprocket 18 are in contact with the transverse rollers 19. The latter are fixed at 9 motionlessly rotatable around their longitudinal

axis. Each cylindrical roller 16 of an individual drive 4 with the help of edges 20 ensures that a corresponding annular section 9 of a tapered drum is held in a vertical plane. In order to carry out the process of constant cleaning of the internal elastic brush-finger coating of each ring section 9 during the rotation of the last from sticking soil particles in the gaps between each pair of ring sections 9, cleaning brushes 21 with a tongue m 22 are fixedly mounted, made of an elastically deformable elastic material.

A device for dry cleaning of the root-and-vegetable crops works as follows;

The actuator 4 by means of the shafts 12, 13 and the sprockets 18 rotates on the rollers 6 the adjacent conical sections 9 in opposite directions, and the frequency of rotation of the sections decreases from the first to the last. With the help of tray 5, a pile of root crops is fed into the inner conical surface formed by sections 9. When the roots and vegetables are interacting with the elastic surface of sections 9, they are cleaned of sticking soil. The soil is sifted between sections 9 and enters the pallet 10. The counter-directed movement of section 9 facilitates more intensive cleaning of the root and tuber crops. Reducing the frequency of rotation of sections 9 from the loading area to the unloading section allows for cleaning with minimal damage to root and tuber crops. Cleaning brushes 21 ridges 22 continuously clean the working surface of sections 9 and keep them in working condition. Unloading tray 11 displays the peeled roots from the device.
