O5 05 Isobenethenia refers to agricultural estates; viaiuiii i CTpoennJO, in particular, to devices for separating stones from the soil and growing them:) What remains are used in stone harvesting equipment. A drum-screw separator is known, consisting of two sections made of steel bars and connected by longitudinal straps with a gap between the turns and rings equal to the minimum size of the stones to be harvested. The surface of the helical section of this separator is soda, which holds the transporting turns, and the exit part of the annular section is the discharge vanes. The disadvantage of this separator is that in the process of operation, plant residues on the longitudinal strands hang and the stones are jammed between the drum rods, which adversely affects the separation. In addition, the quality of the separator depends on the number of stones that fall into the drum. If there are not enough stones for intensive separation, the stones along with the soil and plant residues are discharged into the bunker and removed from the fields, which adversely affects the structure of the arable layer. Closest to the offer, a separating device for masonry masonry is available. containing parallel shafts with discs mounted on them in a shahmatnem order having a multi-faceted working edge 2. A disadvantage of the known device is that the separator should be pre-existing before the operation; 1 grinding of plant residues and soil with heavy disc harrows. Otherwise, the separation efficiency is reduced and the stones, along with plant debris and soil, are discharged into the bunker. As a result, a significant portion of the fertile land and plant debris is exported with stones from the fields, which adversely affects the cTpyKTvpe of the arable layer. The goal of the invention is to increase the efficiency of the separation of stones from plant residues and the earth. The goal is achieved by the fact that the disks provide 1 flexible working elements, each of which is fixed loosely with one end to the face of the disk. In addition, the work item is made in the form of a chain segment. FIG. 1 schematically shows the proposed separation device, side view; in fig. 2 - the same, top view. The separating device of the stone-cleaning maschine is made of frame 1, carrying shafts 2 with disks 3 mounted on them in a staggered order, with a multi-faceted working edge 4, at the edges of which flexible flexible working surfaces are attached. chains. The separating device stone harvesting machines works as follows. On the shaft rotating in one direction, a stone mass is fed. Many-sided working edges of 4 discs 3 crush the soil, which, together with small stones, spills onto the field between the discs 3. At the same time, discs 3 with working SvieMeHxaMH 5 break up lumps of soil and trap plant residues with earth, pulling them into the gaps between discs 3, after whereby the soil and plant residues are dropped by the working elements 5 to the surface of the floor. When meeting the working elements 5 with stones that do not pass between the disks 3, the working elements 5 deviate, bend and pass between the disks 3, and the stones under the influence of the disks 3 move in the direction of discharge. In addition, the work items 5 clean the shafts 2 from plant residues screwed on them. Stones, cleared of plant residues and earth, enter the bunker or the vehicle. The presence in the construction of a device of flexible electrons, freely mounted on the edges of the disks, made in the form of chain segments, allows an increase in the separation intensity, which, in turn, improves the quality of separation of stones from plant residues and earth. Moreover, the use of the proposed separator with flexible elements makes it possible to eliminate the preparatory work carried out before the start of separation, on the grinding of plant residues and soil by heavy disk harrows and, thus, to reduce the mechanical effect on the soil.
