Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to working bodies for the separation of root and tuber crops from impurities. A device for separating the roots from the stones and soil lumps, containing a finger conveyor with receiving and distribution areas, and a puller 1 is known. The disadvantage of this device is that in the flat distribution area of the finger conveyor the components of the processed mixture are located at levels that are not significant, which does not allow for their effective separation. A device for separating root crops from stones and soil lumps, containing a finger conveyor with receiving and distributing areas, and bypass elements 2, is known. A disadvantage of the known device is also the low efficiency of separation of root and tuber crops and impurities. The purpose of the invention is to increase the separation efficiency of the mixture components. This goal is achieved by the fact that the device for separating the roots from the stones and soil lumps contains a finger conveyor with receiving and distributing sections, the distribution section of the conveyor being made curved but curved with alternating signs of curvature, and bypass elements equipped with a puller located after the latter the concave section of the conveyor, and the bypass elements of the concave sections are mounted on a separate common frame, equipped with a vibrator. Moreover, brush beaters are installed above the ascending branches of the valleys of the web to prevent the tubers from rolling. FIG. 1 shows a diagram of the device for. separating the roots from the soil and stones; in fig. 2 is a view A of FIG. one; in fig. 3 - diagram of the interaction of the roots with the finger surface; in fig. 4 is a diagram of the interaction of soil lumps and stones with a finger surface. The device comprises a conveyor 1 with a finger-like surface, the base 2 of which is made with curved elements 3 and 4 curved with a periodic change in the direction of curvature. In sections 5, the base is convex, and in areas 6 - concave (hollow). Behind the curvilinear sections 5 and 6, a puller 7 is installed above the finger surface, made in the form of a conveyor 8 with brush scrapers 9. The device is equipped with conveyors for root and 10 fruits and impurities 11. The bypass elements 4 are mounted on a common frame equipped with a vibrator 12. Above the ascending arms The 13 troughs are provided with brush beaters 14 made in the form of rotating brushes. The device works as follows. A heap of root crops, lumps of soil and stones is fed to the conveyor 1. Clumps of soil and stones are more dense than roots and tubers, so they tend to deform the fingers more strongly and to be located closer to the base of the 2 fingers. But this is prevented by the fact that they have a significantly greater coefficient of friction than the root and tuber crops. On the convex section 5, the frequency of the fingers is reduced, which allows the components to be located closer to the base 2. On the concave section 6, the frequency of the fingers increases, which contributes to the extrusion of the root crops on the tips of the fingers, and the lumps and stones, since they have a significant coefficient of friction, remain trapped between the fingers. The oscillatory movement of the bases of the troughs, carried out with the help of a vibrator 12, intensifies the extrusion of the root and tuber crops to the fingertips. By varying the modes of oscillation, it is possible to choose the optimal parameters for processing different mixtures of root and tuber crops. A multiple change in the direction of curvature allows a difference in the level levels of the dissimilar components to be sufficient for separation. Rotating brush beaters 14, mounted above the ascending arms 13, prevent the accumulation of the roots in the hollows. Next, the pile is fed to the puller 7, the brush scrapers 9 of which, more strongly affect the root crops, direct them to the conveyor 10, and soil lumps and stones, overcoming the impact of the brush scrapers 9, are fed to the conveyor 11. The degree of curvature adjustment allows the device to be adjusted for processing specific pile. The application of the invention will improve the separation capacity of the device.
