(54) DEVICE FOR CLEANING OF SEEDS OF ANTILEY CROPS ON THE ROOT

one

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to machines for harvesting seed of tilled pancakes.

A device for harvesting broom crops at the root is known, which includes dividers made in the form of pallets, a stripping chamber and tines with toothed blades 1.

The disadvantage of this device is the dentate surface of the blades of the stripping beaters, injures the stems of plants and the harvested seeds, and also breaks off part of the panicles, leading to their loss.

The purpose of the invention is to reduce losses and reduce injuries of harvested seeds.

This goal is achieved by the fact that the nozzle chamber is equipped with curtains and a rotating stop, and the working edges of the beater blades are wavy, with the curtains mounted at the entrance of the nozzle chamber, and the rotating stop is at the end of it, under the combing beaters.

In addition, the crests and troughs of the working edges of each of the pairs of mating beater blades enter one another and are displaced sequentially, relative to the previous pair of blades, along helical lines, with the helix lines having the opposite direction.

FIG. 1 shows a diagram of the device; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

The device includes dividers 1 in the form of trays, a camera 2 towels, a stripper tines 3, a rotating stop 4 installed at the end of the tow 2 under a stripper beaters 3, an upper lid 5, conveying elements 6 and curtains 7 at the entrance of the camera 2 tows.

The device works as follows.

Using the hydraulic system of the combine, the device is installed so that the front part of the combing beaters 3 is located below the panicles of the harvested plants and guides it along the row of plants. In this case, the dividers 1 collect the plants and send them to the chamber 2 of the tow. In the combining chamber, plants are captured by waves of ochering beaters 3 and, due to the screw arrangement of the waves, are distributed along the length of the combing beaters. The brushing starts when the height of their position becomes less than the height of the axis of rotation of the tines 3. Some plants having a relatively large height reach the rotating stop 4 and are held by the root system through the gap between the stripping beaters 3 and the speed of the combine . The biters 3, rotating towards each other, peel the panicles of plants and discard the selected grain on the upper lid 5 of the chamber 2, which directs it to the trays to collect the grain. The transporting elements 6 collected grain is fed into the inclined chamber of the combine.

The proposed apparatus allows the removal of varietal seeds without damaging them. At the same time, the seeds are not moistened with the leaves of the leafy stalk mass of plants. The presence of a rotating stop allows you to remove plants of different sizes in height. By reducing the trauma of the seeds, their sowing qualities increase, such seeds are better stored.

The use of the proposed device increases the yield by improving the quality of seed.
