(54) ROTARY CLEANER OF ROOTS FROM REMAINS OF THE BATTLE TO THE ROOT

X

(57) The invention relates to an agricultural technique, namely, aggregates for processing root crops. The aim of the invention is to improve the quality of cleaning tops, reducing the number of piled and damaged roots. The rotor cleaner of root crops from the remains of the foliage to the root consists of shafts 1, on which there are hubs 2 with beaters 4. Beat 4 consists of a leather strip and a spring embedded in it. During operation, the bilas rotate towards each other and apply gliding blows to the roots. Springs beat smother blows and contribute to the scraping of the residual tops. 3 hp f-ly, 4 ill.

The invention relates to the field of agricultural machinery and can be used in machines for cleaning the heads of root crops from tops. The known structure of the root-harvester cleaner from the residues of the tops on the vine, contains two parallel, counter-rotating shafts, carrying the driven and driving members, on which working elements are installed in series, made in the form of closed traction circuits with elastic strips attached to their outer surfaces. A branch of each traction contour has a straight line segment.

The disadvantages of this design are the low quality of the removal of tops, the filling up of root crops, varieties that are highly sown in the soil. The closest in technical essence to the proposed device is a rotary root crop cleaner selected from the tops of the haulm, containing paired, counter-rotating rollers parallel to each other from the drive mechanism, located along the machine's direction of movement and attached to the hubs with radially bilings.

The disadvantages of this design are the low quality of the removal of the tops, the high injury to, the collapse of root crops, high-grade beet varieties sitting high in the soil, for the reason that the billes, when the carrier shafts rotate, diverge along the radius to strike the cornelloid. Since the removal of residual tops from root crops occurs due to knocking down, it is necessary to set either a high frequency of rotation of the shafts or a large mass of beats, but this, in turn, will lead to the aforementioned disadvantages.

The aim of the invention is to improve the quality of cleaning tops, reducing the number of injured and piled root crops.

With the use of the proposed cleanser, the injury and knockout of root crops from the soil will decrease by 40%, and the quality of cleaning of root crops will improve by 30%.

This goal is achieved by the fact that in a rotary cleaner of root crops from tops containing paired, parallel to the drive mechanism, rollers parallel to each other, located along the direction of movement of the machine and mounted on them hubs with radially diverging rows of elastic blades, which are made in in the form of flexible strips with holes, made in chess

The order in which the springs of different elasticity are placed is more elastic at the beginning, less elastic at the end.

In addition, the goal is achieved by

The hubs are made in the form of rings, spring-loaded with respect to the roller, on which the beams are mounted, which are located in one plane of rotation. This is necessary to dampen the impact force at the beginning and in the process.

work.

The goal is also achieved by the fact that there are two or three beams on the hub.

FIG. Figure 1 shows the kinematic scheme of the rotor cleaner; in fig. 2 - the relative position of the rotors above the roots of the root; in fig. 3-4 hub with bilami, side view; in fig. 4 - beat.

The device, a rotary cleaner of root crops from residues of tops on the root, contains shafts 1 on which hubs 2 are located. The turning of hub 2 on shaft 1 is limited by a spring 3, which is fixed to shaft 1 at one end and fixed to hubs 2. Bils 4, which consist of flexible strips 5 and springs 6 mounted in them. At each hub 2, two or three billes 4 are evenly spaced. Carrying shafts 1 are rotated by a mechanism

drives 7,8 and 9.

The device works as follows.

When the unit is moving, the shafts 1 with hubs 2 located on them with beams 4

rotate towards each other due to the drive from the tractor's PTO. The blows 4 apply gliding blows to the root crops by applying a spring 3, which contributes to quenching the impact force to the original

moment and in the course of work, thereby reducing the number of piled root vegetables. The use of springs 6 of varying elasticity along the length of the shaft mounted in flexible strips 5 will allow to achieve high quality of cleaning and reduction in the number of piled root crops due to the fact that 6 haulm residues with minimum impact load will occur here. While rotating

shafts 1, carrying the hub 2 with bilami 4, bilah 4, located on the same shaft, due to the mechanism of drives 7.8 and 9, fall between bilami located on the adjacent shaft,
