Abstract

FIELD OF THE INVENTION The invention relates to agricultural, mechanical engineering. The purpose of the invention is to increase the separation capacity of the device by increasing its technological reliability. The device contains a feeding conveyor, a drum 2 with impaling elements (NE) 3 arranged in rows along a generator, a pressure roller, a puller, a separator, conveyors for root crops and impurities, a tray. NEs 3 are made in the form of knives, the cutting part 1I is directed in the direction of rotation of the drum 2 and is located at an angle ei to the surface of the drum. The knives of the NE 3 have shoulders located behind the cutting part 11 along it, and the cutting part II is crescent-shaped in a wide range 13, each sting being located under the fragrance p to the radius of the drum. When a pile is fed to the drum 2 with NE 3, the root crops are punctured on the sting, loose clumps of soil are destroyed, other clumps of soil and stones are not prickled. Punched components are removed by a puller and fed to the conveyor. 2 hp ff, 3 ill. S (l

FIG. 2

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to working bodies for the separation of agricultural products from impurities.

The purpose of the invention is to increase the separation capacity of the device by increasing its technological reliability.

Figure 1 presents a diagram of the device, side view; figure 2 is a fragment of a drum with nakalshayuschimi elements; in fig. 3 is a section A-A in FIG.

The device for separating the roots of the tubers contains a feeding conveyor 1, a drum 2 with incandescent elements 3 arranged in rows along a generator, a pressure roller 4 and a puller 5, filled in the form of brushes, a screening separator 6, screen 7, conveyors 8 and 9, respectively, for root crops and impurities, tray 10. The puncturing elements 3 are made in the form of knives and the cutting part 11 is directed towards the rotation of the drum 2 and is located at an angle about 60-85 to the surface of the drum

The knives of the elements 3 are made with the shoulders 12 located behind the cutting part 11 along it, and the cutting part 1 is crescent-shaped in the form of a row 13, each sting being at an acute angle P 30-60 to the radius of the drum.

The device works as follows.

Conveyor 1 feeds pre-calibrated heap of root and tuber crops, soil lumps and stones onto drum 2 with filament elements 3 The components of the mixture are arranged along rows of elements 3 and are fed to the pressing roller 4, the pile of which presses them to the cutting part 1I. In this case, the root crops undermine the stings 13, loose soil lumps are destroyed, solid soil lumps and stones do not pile up, and moist clay lumps of the soil, if they are not destroyed under the action of the pressure roller 4, also, like the roots and tubers, prick the elements 3.

After the action of the roller 4, the drum 2 moves the mixture to its vertical section from which the stones.

solid and destroyed soil lumps with the help of a tray 10 are fed to the conveyor 9, and the punctured components are delivered to the puller 5, under the influence of the pile of which they are removed from the elements 3 and using the screen 7 are fed to the separator 6. In this case, under the influence of the pile and when interacting with the screen 7 lumps of soil are destroyed, become smaller in size than the root and tuber crops, and sifted on the separator 6, entering the conveyor 9, and the root crops are sent to the conveyor 8.

During the nakalgaani, the shoulders 12 prevent the full cutting of the root and tuber crops, and the sticks located at an angle of / 3 to the radius of the drum

on, contribute to a strong retention of impaled roots and tubers. The cutting part 11 arranged at an angle of 60-85 allows the mixture to be processed without jamming of strong impurities between the elements 3 and the drum 2. I

Claims (3)

Invention Formula one .
