SU1736367A1 - Device for cleaning roots and tubers from impurities - Google Patents

Abstract

Usage: in cleaning devices, mainly in beet harvesting machines. SUMMARY OF THE INVENTION: The device comprises two inclined conveyors 1 and 2, forming with their canvases 3 and 4 a V-channel, drive mechanisms 8 and 9, which provide the webs 3 and 4 with a different speed of movement relative to each other, and an adjusting device 10 for changing the angle the inclination of conveyors 1 and 2. The latter is in the form of a screw rod with right- and left-handed threads, on which are mounted nuts with hinges 13 and 14 fastening conveyors 1 and 2. 1 Cp. f-ly, 2 ill.

ftsg.g

The invention relates to agricultural machinery, in particular to the separation of the working bodies of root harvesting machines.

The purpose of the invention is to improve the quality of work.

Fig, 1 shows a cleaner of root crops from impurities, a general side view; in fig. 2 is a view A of FIG. one "

Root crop cleaner contains two longitudinal conveyors 1 and 2 consisting of canvases 3 and 4, installed V-shaped at an angle of 10-18 ° to each other. Conveyors 1 and 2 are mounted on frame 5 by means of double hinges 6 and 7 located above the upper edges of conveyors 1 and 2. Conveyors 1 and 2 themselves are driven by cardan gears 8 and 9. The lower edges of conveyors 1 and 2 are connected to each other. friend with the help of a screw rod with a handle 10 with right and left threads and hinges 11-14. The cleaner also includes a feed conveyor 15 and a discharge conveyor 16. Cloths 3 and 4 are tapes with protruding cantilevered fingers. The drive of the conveyor 1 is provided with a device (not shown) for increasing the speed of movement of its web 3 in such a way that (s (ai.

During operation, the cleaner conveyor 15 feeds the beet roots to be cleaned into the gap between conveyors 1 and 2, as a result of which they fall between blades 3 and 4, and due to the fact that the angular speed w of the drive of the conveyor 1 is greater than the angular speed 0 of the conveyor drive 2 , the roots rotate around their own axes of rotation and take the position of the tail parts downwards. At the same time, since the installation angle of the webs 3 and 4 is on average equal to the angle of taper

beet roots, regardless of the size of the roots, they are located at different levels of height, but are completely in contact with blades 3 and 4. As a result of this contact and beet root turns, they are effectively cleaned of impurities, while the fingers of the canvases not only release the roots sticking soil, but also plant residues are captured and taken out of the limits of the purifier. As they advance in height of the webs 3 and 4, the roots are moving along the webs and, having cleared.

If the average sizes of the root crops are significant, then by means of the handle 10 the screw rod is rotated, resulting in the hinges 13 and 14 approaching each other and the collapse angle

The V-shaped cross section of the webs 3 and 4 is enlarged.

Claims (2)

Claims t. The cleaner of root crops from impurity, containing the drive, longitudinal conveyors installed V-shaped at an angle to each other, characterized in that, in order to improve the quality of work, the conveyors are installed at an angle of 10-18 ° to each other and equipped with an adjusting device to change the angle of inclination, while on the conveyor belts the fingers are mounted, and the drive of one of them is equipped with a device for increasing the speed of the conveyor belt. 2. The cleaner according to claim 1, in connection with the fact that the adjusting device is made in the form of a screw rod with a right- and left-handed thread on which nuts are mounted that are hinged to the lower parts conveyors. in iiiniii i i 11 11 i i 11  I I M 1 | II I I I I Illll III Mill I I G  i 111 i i 11ii i iO 70 Fiá.1 iiiinii I I I Illll III Mill I I G i i 11ii i 76 S
