Abstract

The invention relates to the field of agricultural engineering. It allows you to improve the quality of seed treatment and performance when removing the pericarp. The cylinder I of the device is installed with the possibility of reciprocating motion. Inside the cylinder 1 is placed with the possibility of rotational movement of the rotor 5. On the inner surface of the cylinder 1 and on the outer rotor 5 there are annular grooves 2. A window 10 is cut in the cylinder for mounting the hopper 11, which feeds beet seeds into the device. To withdraw the treated seeds, seed ejectors are installed in the lower part of the window 10 in the form of a tooth comb. At the bottom of the grooves 2, elastic elements 7 are installed for supplying seeds to the grooves 2 of cylinder 1. For orientation of the seeds, bunker II is equipped with vertical partitions 12 and blowers 13 are installed in the form of impellers above each groove 2 inside the bunker. When the rotor rotates, the seeds are tightened between the cylinder and the rotor, and a part of the pericarp is cut into the cylinder groove. 3 h. the item of f-ly, 3 nl. (L

The invention relates to the field of agricultural engineering and can be used for processing beet seeds on collective and state farms, as well as in family processing plants.

The aim of the invention is to improve the quality of seed treatment and increase the productivity of the process of removing the seed of the pericarp.

FIG. 1 shows a schematic of an apparatus for removing pericarp seeds; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a view B in FIG. 2

The device for removing the pericarp of beet seeds consists of a cylinder 1, on the inner surface of which annular grooves 2 are made. The cylinder is mounted in slide bearings 3 and is driven back and forth by one of the known mechanisms, for example, a crank-11 atunum mechanism 4. Inside the cylinder has a rotor 5 with grooves 6, which are made on the outer surface of the rotor and at the bottom of which elastic elements 7 are located. The rotor 5 of the pins 8 rests on the bearings 9 and is driven in rotational motion.

A window 10 is cut out in cylinder 1, in the upper part of which a hopper 11 with partitions 12 and a supercharger 13 seeds is installed, a comb 14 with teeth by ejector pads 15 is installed in the lower part of the window.

The device works as follows.

The pre-calibrated beet seeds are poured into the bunker 11, in which, due to the partition, they are oriented along the lesser axis along the axis of the rotor and by the supercharger 13 are directed into the grooves 6 of the rotor 5.

As the rotor rotates, the seeds are drawn between the cylinder and the rotor. Since the cylinder reciprocates, then at the time of coincidence of the contours 2 and 6, the elastic elements 7 raise the fruit up to an amount less than or equal to the depth of the cylinder groove,

Further movement of the cylinder, the part of the pericarp, which has fallen into the cylinder groove, is cut off by the edges of the grooves. For this, in order for the cut to be cleaner, the rotor and the cylinder between them have a minimum clearance, practically a sliding fit. When the rotor rotates, the fruit twists around its axis, the next part of the pericarp falls into the cylinder groove and is cut off. Treated seeds and cut off particles of the pericarp rotor 5 takes out of the working body in the lower part of the window 10 and they fall on the discharge chute 16. If the seeds get stuck in the rotor groove 5, they are pushed out of the groove by ejector 15. Later on, the seeds can be directed to cleaning machines, treaters, etc.
