Description

one

The invention relates to agriculture and can be used to clean the seeds of agricultural crops.

The aim of the invention is to improve the quality of the separation process of seeds of various shapes, elasticity and roughness by providing a continuous feed to the separating surfaces of a previously divided mixture.

Fig. 1 shows the principle-constructive scheme of a vibro-friction seed separator; Fig, 2 is a structural diagram of the power supply device.

The vibro-friction seed separator (Fig. 1) includes a working member consisting of the rowwise located separating surfaces I having a double longitudinal-transverse inclination to the horizon. The separating planes 1 are interconnected by means of clamping bolts 2 tared at the height of the sleeves 3 and washers 4, and rigidly attached to the frame 5 of transverse inclination. The latter is fixed in the frame 6 of the longitudinal slope. The longitudinal angle of inclination of the working surfaces 1 to the horizon is controlled by the mechanism 7, the transverse angle by the mechanism 8. Through these mechanisms, the separating surfaces 1 are attached to the vibratory tolu 9, which is installed on the spring of the elastic suspension 10, symmetrically located on the support plate 11 of the base frame 12. To the vibration table 9 , an unbalance vibrator 13 is mounted, mounted so that the lines of action of the disturbing forces are left

an angle with the direction of increasing the rise of the working planes 1. The vibrator I3 is set in motion from the AC motor 14 through the variator 15 turns, intermediate gear 16 and the elastic coupling 17. The vibrator drive 13 is mounted on the auxiliary frame 18 fixed on the base 12, Initial feed the mixture is carried out from a hopper 19, rigidly fixed on the base 12, with a flexible adapter 20, by a feeder 21, which is fixed on the vibrating part of the machine (frame 5 of transverse tilt) to prevent seed arising . In the feeder 21, the feeding windows 23 are made in a plane perpendicular to the plane of vibration from the upper edge of the separating surfaces 1, with guide plates 25 for each window 23 inside the housing of the feeding device 24, and outside the fixed trays of the distribution surface 26 that they are formed in the longitudinal direction represents the line of the largest slope, i.e. is horizontal with a sharp angle, and in the cross is a straight line, the slope of which (ot) coincides with the longitudinal slope ot of the separating surfaces. There are eight receivers 22 for collecting the separation products in the vibro-friction seed separator.

Thus, the proposed invention - continuously feeds the previously divided treated material onto the separating surfaces.
