The invention relates to an agricultural technique, in particular to the separating organs of stone harvesting machines, and can also be used in devices for harvesting tubers and in rowers with disc separators.

A stone harvesting machine separator is known, which includes successively arranged parallel shafts rotating 3 in one direction with disks 1 mounted on them in a checkerboard pattern.

However, the operation of the machine must be preceded by pre-crushing of plant residues and soil by heavy disc harrows, as plant residues are wound on the shafts, thereby reducing gaps between the discs. In addition, the operation of the separator is hampered on wet soils due to soil sticking to the lateral planes of the discs, as a result of which the quality of separation and the productivity of the machine are reduced.

A rotary separator, predominantly a stone harvesting machine, is also known, which contains disks mounted on a rotating shaft, between which cleaners are placed, made in the form of cleaning elements 2 that hang freely on the separator shaft.

The cleaning elements of this separator are made in the form of sterols equipped with brush elements.

A disadvantage of the known separator is that it does not provide cleaning of the shaft from the plant residues screwed on it. During the operation of the separator, a rod hanging free on the shaft swings in the center between the discs, as the brush elements mounted on it rest against the lateral surfaces of the discs, while the plant residues are wound on the shaft on both sides of the rod. As the plant residues grow on the shaft, the brush elements first press them against the shaft and, by the same token, provide a more dense vegetation on the shaft. Further winding vegetation on the shaft leads to the bending of the brush elements from the side surfaces of the disks and to a decrease in the working lumen of the separator. In addition, during operation, the brush elements become clogged with soil, which adversely affects the quality of separation.

The purpose of the invention is to increase the productivity and quality of separation.

The goal is achieved by the fact that in a rotary separator, mainly a stone harvesting machine, containing disks fixed on a rotating shaft, between which are cleaners, made in the form of cleaning elements that hang freely on the separator shaft, in the form of chain rings.

FIG. 1 shows a rotary separator, side view; in fig. 2 - the same view

A rotary separator, predominantly a stone harvesting machine, consists of a frame 1 on which a ploughshare 2 is successively mounted, parallel rotating shafts 3

5 with disks 4 rigidly attached to them in a chessboard pattern and with cleaning elements in the form of chain rings freely floating between the disks 4. At the end of the frame 1, a discharge conveyor 6 is mounted.

Rotational separator stone harvesting machine works as follows.

When the machine moves to the rotating in one direction, the separating shafts 3 from the plowshare 2 come in stony

5 weight.

Under the influence of rotating disks

4 kamenista mass intensively loosened and transported in the direction of rotation of the disks 4, while the soil is sifted through the gaps between the discs 4. Simultaneously free-hanging chain rings

5 rotate on the shafts 3 between the discs 4, maintaining a position close to the vertical, due to its weight, and cleans the side surfaces of the discs 4 from adhering soil, and also prevents the winding of vegetation on the shafts 3.

During operation, the chain rings 5, having made oscillatory movements, are constantly self-cleaning. From the shafts 3, the peeled stones arrive at the discharge conveyor 6, which unloads the stones in a number of vehicles.

The use of a separator in stone harvesting machines will improve the quality of soil separation, increase machine productivity and make it possible to use these machines on wet soils. In addition, the use of a separator will make it possible to exclude the preparatory work carried out before the start of cleaning the stones to grind the soil with heavy disk harrows.
