SU1237112A1 - Rotary cleaner of root vegetables from plant top - Google Patents

Description

f

The invention relates to agricultural machinery engineering, in particular to devices for the treatment of residues of leafy tops on the heads of the roots of predominantly fodder and sugar beet.

The aim of the invention is to improve the quality of cleaning of root crops from tops.

FIG. 1 shows a single rotor device, rear view; Fig.2 is the same, side view; in fig. 3 shows the relative position of two adjacent rotors above the roots of a row; in fig. 4 - mutual arrangement and drive of two adjacent rotors in the plan; in fig. 5 is a flow chart of the joint operation of the harvesting machine and rotary cleaners.

The rotor cleaner (root crops from tops) consists of a hub 1, along the edges of which disks 2 are fixed with holes evenly spaced around the circumference. At the same time, the holes of one disk with respect to another are mixed, by half a step. On these holes, bolts 3 secured figured fingers or nozzles 4 with a hole 5, onto which beats 6, made of rubber-fabric tubes, are tightly mounted and fixed. The width of the fingers (nozzles) 4, with which they cover the disks 2, is greater than the thickness of the disks, and the diameter of the holes in the disks is larger than the diameter of the bolts that secure the fingers to the disks. Due to this, the bolts fixed on the fingers can freely deviate both in the plane of rotation and to the right or to the left of it when meeting with the root crop and apply soft gliding blows to it.

At the ends of the blades there are additional holes 7, thanks to which they can be fixed on the nipples 4 by either end or rotated around its axis. This extends the service life of the tubular beats. For the same purpose, the steps are made symmetrically and can be rotated 180 ° on the leading 1x rollers 8. The pair of rollers 8 are arranged in parallel along the direction of the movement} 1and the length and opposite to the rotation in 1 of the horizontal plane. On the drive rollers, the hubs are fixed using E1 key 9. The leading rollers of each adjacent pair of rotors are mounted in a horizontal plane along each side of the root

fruits. Each pair of rotors rotates counter from top to bottom, and is carried out from the drive mechanism on the frame through conical pairs 10.

The planes of rotation of the adjacent rotors alternate with each other. Half a step is shifted and the alignment beat on adjacent rotors. All this contributes to the application of uniform transverse strokes to the right and to the left from above on the heads of the root crops and ensures their stability against lateral blockages. Due to the fact that the beats can freely deviate to the sides from the plane of rotation, the blockage of the roots from their influence and in the direction of their movement does not occur.

The horizontal distance between the driving rollers of adjacent rotors and the height of their location above the surface. The soils are determined from the condition of the required overlap of the work of the beater, both when meeting a large and small root vegetable.

The number of discs on the hubs and the beats fixed on them is determined from the permissible rate of avoidance of the hits on the heads of the root crops (if they are not damaged) and from the required frequency of hits hit on the length of a row of root crops, depending on the speed of movement of the harrowing machine. . .

In general, the haulm includes a disk tool I1, an inclined conveyor 12, a side lock 13 and rotary cleaners 14.

The operation of a haulker equipped with rotary cleaners is as follows.

The plant, cut off by the disk working device 1I, is thrown onto the inclined conveyor 12 and then the side conveyor 13 is reloaded in a row by the traveling transport. The remains of the tops of the roots are covered (cleaned) with rotary cleaners 4,. mounted on the back of the haulter and driven in rotation from the tractor's power take-off shaft. The rotor cleaners 14, when moving over rows of root crops with bilami 6, strike the heads of the roots from top to bottom and upholster the remaining 55 to the soil. The cleaned roots are removed following the RKS-4 harvester, and the goods are also in a number of vehicles.
