SU1228907A1 - Seed separator - Google Patents

Description

one

The invention relates to devices for cleaning and sorting seeds of agricultural crops, mainly vegetable, bast, medicinal and flower plants, and can be used for the separation of other bulk materials.

The purpose of the invention is to improve the accuracy of the separation of multicomponent mixtures by preventing the elongated seeds from rolling.

Fig. 1 shows a diagram of the movement of the mixture through the working member; figure 2 is a structural diagram of the proposed separator.

The separator includes a working body in the form of one or several non-perforated plates 1, on the surface of which electrodes 2 of alternating polarity are located at an acute angle to the longitudinal axis of the separator. The plates 1 are mounted on the vibrating table 3, which is connected to the vibration exciter 4. The vibrating table rests on an elastic suspension in the form of compression springs 5 installed on the base 6. The mixture is fed to the feeder 7, and the receivers 8 are used to collect the separated fractions. installed with a slope at an angle a in the longitudinal direction and at an angle p in the transverse direction. Mechanisms 9 and 10 are used for adjusting tilt angles.

The separator works as follows.

The outgoing seed mixture of nitrate 7 is placed on plates 1, which are vibrated by vibration exciter 4. Under the influence of vibration on an inclined surface, the mixture is divided into elongated rough particles that are transported along evened trajectories and smoother, rounded, which are transported along the trajectory of m greater curvature. The difference in the trajectory / expansion of those and other particles is due to the greater force of pressing the elongated particles by the electric field, which increases the difference in the strength of friction due to those and other particles. The vibrations of the working order provide an upward movement of rough particles with more force than smooth rounded ones.

Since in the separator the electrodes are spaced at an acute angle c: to the longitudinal axis of the working shaft, the elongated particles, oriented perpendicularly to the electrodes, turn their long axis toward the transverse inclination at an angle of 90 ft. This prevents the elongated particles from rolling in the non-verse direction. Angle q; the location of the electrodes depends on the particular seed mixture and is determined by the ratio of the lateral angle (3 cac. of a young working oragan and the longitudinal angle).
