Description

The invention relates to agricultural machinery and can be used in the separation into fractions of onion culture seeds,

The purpose of the invention is to increase the efficiency of the separation

Figure 1 shows the device, the general view; figure 2 - the upper part of the sieve mill with suspension, axonometric:, in Fig „3 - node I in figure 2; FIG 4 is the Ina node of FIG. 2; in Figs. L-7, view A on at various positions of Krivoshchips.

The device contains a sieve mill 1, suspended on m 2, mounted on its sidewalls, carrying in parallel siets 3-5 installed one above the other and a sloping board b, at the end part of which are receiving receptacles 7-10. The free ends of each pair of tg 2, located on both sides of the sieve mill, are connected by means of hinges, respectively, to one of the two cranks 11, made in the opposite direction on the end sections of the transverse relative to the sieve mill 12, which are connected to the rotation mechanism 13 Crank 11 represents opposite protrusions 145 in slot 15 of which axle 16 is attached, with which pivotally connecting rod 2 is pivotally connected, and threaded part 17 of axle 16 is supplied with nut 180

A connecting rod 19 of an eccentric vibration exciter 20 is hinged to the lower part of the sieve mill 20. A feed elevator 21 is provided for feeding the sieve mill 1 of the material to be processed. The loading hopper 22 and the perforated ramp board 23 9 are placed between the fan 24 and the camera 25 of the Sieve 3 -5 are made of T-shaped cross-sectional longitudinal grates 26, assembled on threaded rods x 27 and fixed at the same slot within the sieve with a slit gap 28 with nuts 29. The ends of the rods 27 are fixed in the side panels of the sieve Thane.

The device works as follows.

With the aid of the vibration exciter 20, the sieve mill 1 is driven in a reciprocating motion, and by means of m 2 and cranks 11 sieves

The mill will be vibrated in a plane perpendicular to its reciprocating motion. This is achieved by rotating the shafts 12 with the same angular velocity and the in-phase rotation of the cranks 11 connected to the rods located on one side of the sieve mill. The amplitude of oscillations of the sieve mill is regulated by shifting into the slots x 15 the lugs 14 of the axis 16, followed by its fixation with the nut 18.

The seed material to be sorted is fed by the elevator 21 to the hopper 22, from where it enters the cattle board 23 blown by the fan 24, through perforations of which light impurities into the chamber 25 are removed. On the surface of the sieves, the material layers are efficiently mixed and the teeth move along the perpendicular path sieves in the direction of unloading material. The T-shaped profile of the grates 26, regardless of the inclination side of the section, when the mill oscillates, facilitates the passage of teeth, the dimensions of which do not exceed the width of the gap 28, since the specified geometry of the profiles makes it difficult to hook the teeth behind their edges and clogging the gap gaps 28, which allows refuse to use the sieve gap cleaning device. The same profile provides sufficient rigidity of sieves.

Depending on the excreted fractions of the garlic seed, the gaps 28 in the sieves regulate. For this, the ends of the threaded rods 27 are released from the sides, the nuts 29 loosen the fixing of the grates 26, move (push) the latter relative to each other, and if necessary add or remove the extra grates and fix them again with the nuts 29 .
