Description

 The invention relates to an agricultural technique, in particular a technique for processing agricultural raw materials, and can be used for peeling and separating the outer skin from peanut seeds and other legumes.

The purpose of the invention is to reduce the fragmentation of seeds,

Installing the seed pre-calibration drum over the feeder, securing the longitudinal slats of variable width on it so that the gaps between the slats, as well as the gap between the shelling rollers, have the same value varying from one drum end to another and making the rollers elastic with a ribbed surface allows reduce crushing of seeds with different fractional characteristics in thickness and width.

Figure 1 shows the scavenger, in general view; figure 2 - drum pre-calibration and shelling rollers, top view.

Luster contains frame 1, hopper 2 mounted on it, preliminary calibration drum 3 with longitudinal bars 4 of variable width fixed on it and screw winding 5 on its inner surface. The damper also contains a feeder 6, shelling rollers 7 placed underneath it, a cleaning system 8 and a drive 9. Drum 3 is installed above the feeder 6. The gaps (a - c) between the drum bars, as well as the gap (ai - BI) between the shearing rollers have the same value changing from one end of the drum to another. Shelling rollers are made elastic with a ribbed surface and are located in two russes: in the upper rushe there are two rotating oppositely at different speeds, in the lower one - located between the two upper ones.

Luster works as follows.

The beans fed into the interior of the drum 3. the preliminary calibration, where they are moved along its inner surface with the aid of a screw winding 5, fail

in gaps of variable section, depending on the sizes,

The calibrated beans roll along the walls of the hopper 2, are picked up by the blades of the feeder 6 and fed into the gap between the rollers 7 of the upper tier without changing the position of the beans along the forming rollers after the passage of the drum 3.

Rotating at different speeds, the rollers 7 of the upper tier, due to their rough, ribbed elastic surface, remove the shells of the beans not only in the radial direction, but also in the tangential direction.

Due to the fact that the working gap between the shelling rollers 7 is set in the same way as the gap between the strips 4 of the pre-calibration drum 3, the beans fall and the shells in the areas between the rollers 7 corresponding to their sizes. As a result, crushing of husked seeds is reduced.

The final cleaning of the beans is provided by the third drum, located under the upper two.

Next, the husked beans are fed to the cleaning system 8, where separation is carried out in a known manner and device, for example a wind-time mill, into conditioned and substandard seeds.
