Abstract

The invention relates to the field of agriculture and is intended for cleaning and sorting seeds according to a complex of physicomechanical properties, as well as for Separating bulk materials. The goal is to increase the quality and productivity of separation by providing the same rate of introduction of bulk material onto friction surfaces, (FP) 1 as a bag. They have a longitudinal-transverse slope to the horizon. VF 1 and vibration exciters 2 and a feeder 3 are connected with the FP 1 with partition walls со with СО 4 CO to 4 equidistantly mounted in its housing.

The invention relates to the technique of separating bulk materials and can be used in agriculture for cleaning and sorting seeds of agricultural crops according to a set of physicomechanical properties.

The aim of the invention is to improve the quality and productivity of separation by providing the same rate of entry of bulk material on the friction surfaces.

Figure 1 shows the basic structural scheme of the separator; Fig. 2 is a diagram of the arrangement of the partitions, the control flap and the upper sliding part.

The bulk materials separator consists of a package of friction surfaces installed parallel to one another, surfaces 1, having a longitudinal-transverse inclination to the horizon, vibration exciters 2 connected to surfaces 1, feeder 3, in which each subsequent equidistant partition 4, supplying seeds on the underlying separation surface at the point of reception of the material, set below the previous one at a constant value, and the control flap 5 is located at the same distance from the upper edges of the partitions 4, the feeder 3 is full A rigidly coupled damper 5 is installed in the upper longitudinal part 6 of the housing, which is vertically extended. A transition elastic nozzle 8 is installed between the feeder 3 and the hopper 7. The collected material goes to the feeder 3 to collect. Moving on them, they are brought into OP 1 at a given rate of entry. Under the influence of the directed vibrations, the seeds move along the FP) depending on the properties of the components of the mixture along different trajectories. The collection of the separation products is carried out at the exit from the FP 1 to the receivers 9. 1 Cp. f-ly. 2 Il.

Separation products in the separator are equipped with receivers 9 of separation products at the outlet of the surfaces I. All nodes are mounted on the frame 10.

The device works as follows.

The material to be processed from the hopper 7 enters through the flexible adapter 8 to the feeder 3. From the regulating flap 5 installed in the additional housing 6 of the feeder 3, the seeds go to the partitions 4 with the lower curved edges. Moving on them, they are down to

separating surface 1 at a predetermined entry rate. For this purpose, the adjusting valve 5, by moving the upper part 6 of the body relative to the lower part, is set at a certain distance from the upper edges of the partitions 4 (depending on the initial seed material). Under the influence of vibrations generated by vibration exciters 2, the treated material moves along the separating surfaces 1, depending on the physicomechanical properties of the mixture components along different trajectories

receivers 9 division products.

Claims (2)

1. Separator of bulk materials, including a package of friction surfaces installed in the package parallel to each other with a longitudinal-transverse inclination, vibration exciters associated with friction surfaces, receivers of separation products at the outlet of friction surfaces, a feeder with partitions equidistantly installed in its housing with curved bottom edges that form the channels for the individual input of material on the friction surfaces, the gate valve installed in the feeder above the partitions, distinguishing This is due to the fact that, in order to improve the quality and productivity of separation by ensuring the same speed of insertion of light material onto the friction surfaces, the upper edge of each subsequent partition is located below 049244 edges of the previous, forming a channel for the individual input of material on. The friction surface is located opposite, the guide valve is installed at the same distance from the upper edges of the partitions with the possibility of adjusting this distance. W 2. The separator is n.i, about tl and is due to the fact that the feeder body is made telescopic with the possibility of sliding apart in height, while the caddy damper is guided by f5 to the upper mobile part of the body.
