Description

(54) PNEUMATIC COLUMNER BALLON

one

The invention relates to agricultural machinery, in particular, to devices for the destruction of soil lumps.

Known cylinder-kombodavitel, containing, shaft with face discs and elastic tire 1.

A disadvantage of the known construction is the incomplete destruction of soil lumps.

The purpose of the invention is to increase the efficiency of destruction of soil lumps.

This goal is achieved by the fact that in the cylinder the cylinder the shaft is hollow and connected to a source of compressed air, the shaft and the tire having holes that are connected by hoses, and the cylinder cylinder is equipped with pressure-acting valves located in the holes of the tire.

In addition, the holes in the tire are located along a helix.

FIG. 1 shows a schematic diagram of a potato harvester, in the scheme of which the proposed pneumatic cylinder-composer is used, side view; in fig. 2-

Pneumatic cylinder-komkodavitel enters the scheme of the potato harvester

The machine includes successively mounted on the frame undermining share I with openings connected by nozzles 2 through receiver 3 to compressor 4, separating elevator 5 with overhead

10 by its surface using a pneumatic destructor 6, consisting of 5 lugs mounted on nozzles and installed with a certain pitch over the entire width of the elevator, a pneumatic cylinder-composer 7, working in combination with a vortex-rotating cylinder 8, a screen 9, a topper 10 in the form of two bands conveyors and cross conveyors 11 and 12 for removal of potatoes and impurities respectively. The cylinder 7 contains a shaft 13 with end discs and an elastic tire 14. The shaft 13 is hollow and is connected to a source of compressed air. Shaft 13 and tire 14 have holes 15 and 16 which are connected by hoses 17.

In the openings 16 of the tire 14, pressure-acting valves 18 are placed, which have axial 19 and radial 20 channels. The holes 16 are located on the surface of the tire 14 along a helical line.

The process carried out by the machine proceeds as follows.

The tuberiferous stratum, excavated by the ploughshare 1, is preliminarily destroyed by compressed air and enters elevator 5, where it is additionally processed by jets of compressed air coming from the tips of pneumatic destructor 6 and separated.

Undestructed soil clumps, plant mixture and tubers pass between the cylinders 7 and 8, while the components of the mixture, pressing on the valves 18, automatically supply compressed air to the processing zone of the mixture. The latter, simultaneously with the compressive force, is exposed to high-velocity jets of compressed air, which increase the effect of the destruction of soil lumps.

The mixture treated with cylinders 7 and 8 enters the surface of screen 9, which separates the soil and transports the remaining mass in the direction of the topper removal 10. The tubers then roll v

on the cross conveyor 11, and vegetable impurities are fed to the conveyor 12. Thus, the use of the proposed pneumatic cylinder in a potato harvesting machine makes it possible to increase the destruction efficiency of soil lumps.
