Description

The invention relates to agriculture, namely to the cleaning of grain, and is intended to separate the flow of bulk materials.

A device for separating the flow of bulk materials (RU 2341954 C2, A01F 12/46, 12/26/2006), containing a movable stabilizing tank with outlet channels of circular cross section and valves in them, which with the help of springs is suspended from the frame and can freely move along guides from the effect of bulk material so that when moving the tank, the discharge characteristics of the outlet channels are regulated.

The disadvantages of the known device are the design complexity and low reliability due to aging of the springs (reduction of their elasticity) and jamming of valves with large impurities.

A device for separating the flow of bulk materials (RU 2459405 C1, A01F 12/46, 08/27/2012), containing a stabilizing tank, a vertical side wall with outlet channels, separated strips, a housing with a vertical partition, pipes.

A disadvantage of the known device is the low consumption of bulk materials through the outlet channels in the vertical wall, which leads to an increase in its mass, dimensions and reduction in the scope due to limitations in the layout of the device by technological height in existing complexes of machines for processing grain.

The purpose of the invention is to increase the flow characteristics.

This goal is achieved in that in a device for separating the flow of bulk materials containing a stabilizing tank, outlet channels separated by strips, a housing with a vertical partition, pipes, according to the invention, the strips are offset relative to each other in a horizontal plane and arranged vertically in the form of an ascending cascade in the direction discharged flows of bulk material.

The invention is illustrated by drawings, where figure 1 shows a General view of a device for separating the flow of bulk materials, figure 2 - view a in figure 1, figure 3 - view B in figure 1.

A device for separating the flow of bulk materials contains a stabilizing tank 1, outlet channels 2, straps 3, the housing 4 with a vertical partition 5 and the nozzles 6 attached to it.

A device for separating the flow of bulk materials works as follows.

Grain is supplied to the stabilizing tank 1 and, as it accumulates, it is discharged into the cavity of the housing 4. With an increase in the grain supply to the stabilizing tank 1, the number of outlet channels 2 included in the work through which the grain flows out increases and the flow characteristics of the nozzles 6 increase. stabilizing capacity 1 the number of discharge channels included in the operation and flow characteristics of the nozzles 6 is reduced. Thus, the process of auto-regulation and maintenance of the stabilizing layer of grain in the range excluding arch formation is carried out. The installation of a vertical partition 5 of the housing 4 symmetrically (with the division of the living section of the outlet channels 2 into equal parts) ensures equal flow rates through the nozzles 6 when the flow of grain from the outlet channels sequentially included in the work 2 is filled. The strips 3 (unlike the prototype) do not interfere with the outlet grains from the stabilizing tank 1, and the discharge channels 2, formed by the upper edge of the previous strip 3 in the ascending cascade and the lower edge of the next, are located vertically, which provides a multiple increase in p similarities in their equal geometrical parameters. With an increase in the flow characteristics of the device for separating the flow of bulk materials, prerequisites are created for reducing its dimensions, material consumption and expanding the scope.
