Description

The invention relates to agriculture and is intended to separate the flow of bulk materials.

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

A disadvantage of the known device is the low quality of the separation of the flow of bulk materials when they are asymmetrically placed in a stabilizing tank relative to the partition of the housing, dividing the living section of the discharge channels into equal parts. In this case, the stabilizing layer of bulk material is formed with a difference in height relative to the outlet channels, which leads to the outflow of exhaust flows through a different number of outlet channels in the left and right parts of the device - reducing the accuracy of separation of the flow of bulk materials. In addition, the outflow of bulk material through the upper outlet channel is unfilled, which introduces an additional error in the division of flows.

A device for separating the flow of bulk materials (RU 2341954 C2, A01F 12/46, 12/27/2008), containing a movable stabilizing tank, springs, guides, upper and lower crawlers, upper and lower stops, bends in which the shaft is placed valves, one end of the shaft is equipped with a rotary lever pivotally connected to the rod, the second end of which is attached to the frame (selected as a prototype).

The disadvantages of the known device are the design complexity, due to the presence of a shaft with valves inside the bends, pivot arm, traction; low technological reliability due to the probability of jamming of valves with large impurities; insufficient quality of separation of the flow of bulk materials due to errors in the angular placement of valves on a common shaft.

The purpose of the invention is improving the quality of separation of the flow of bulk materials, simplifying the design.

This goal is achieved by the fact that in the device for separating the flow of bulk materials containing a movable stabilizing tank, springs, guides, upper and lower crawlers, upper and lower stops, taps, frame, according to the invention, the movable stabilizing tank is paired with a stationary sliding wall fixed to frame and overlapping rectangular lateral outlet channel, mating with branches.

The invention is illustrated by drawings, where in FIG. 1 shows a General view of the device for separating the flow of bulk materials in the extreme upper position of the movable stabilizing tank, when its position relative to the stationary sliding wall prevents the flow of bulk material through a rectangular lateral outlet channel (solid lines), and in the extreme lower position of the movable stabilizing tank, when the height h of the rectangular lateral outlet channel is maximum (dashed lines), in FIG. 2 is a view A in FIG. 1 in the intermediate equilibrium (working) position of the movable stabilizing tank, in FIG. 3 is a section BB in FIG. one.

A device for separating the flow of bulk materials contains a movable stabilizing tank 1, taps 2 with a vertical partition 3, a fixed gate wall 4, guides 5, 6, 7, frame 8, springs 9, upper half 10, lower half 11, upper limiters 12, lower limiters 13, a rectangular lateral outlet channel 14.

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

In the movable stabilizing tank 1 (Fig. 1), which is in its highest position, defined by the upper stops 12, due to the preliminary tension of the springs 9, when the height h of the rectangular lateral outlet channel 14 is minimal and the outflow of bulk material through the taps 2 is impossible, loose material. As bulk material accumulates in the movable stabilizing tank 1, its mass with the material begins to stretch the springs 9, it begins to move vertically down the guides 7, interacting with the upper 10 and lower 11 creepers. This increases the height h of the rectangular lateral outlet channel 14, formed by a fixed sliding gate wall 4, located in the guides 5, mounted on the frame 8, and the bottom of the movable stabilizing tank 1, begins to flow loose material, which is separated by a vertical partition 3, centered by the guides 6, on two equal flows and enters the bends 2. With the further movement of the movable stabilizing tank 1 down, the height h of the rectangular lateral outlet channel 14 increases, the flow rate expires him through it bulk material. The extreme lower position of the movable stabilizing tank 1 is determined by the lower limiter 13. When the flow rate of bulk material exceeds its supply, the amount of material accumulated in the movable stabilizing tank 1 will decrease, the force of the springs 9 will exceed its weight with the bulk material, and it will begin to move vertically upward, decreasing the height h of the rectangular lateral outlet channel 14 - reducing the flow of bulk material. At some point in time, the process stabilizes. In this case, the flow rate of bulk material through taps 2 is aligned with its supply to the movable stabilizing tank 1 - the process proceeds in automatic control mode. The mass of bulk material in the movable stabilizing tank 1 determines the magnitude of the control action on the change in height (area) of the rectangular lateral outlet channel due to a change in the position of the movable stabilizing tank 1 relative to the stationary sliding wall 4, as a result of which the flow rate of the granular material to its supply is achieved. The coupling of the movable stabilizing tank 1 with a fixed gate wall 4, mounted on the frame 8 and overlapping a rectangular lateral outlet channel 14, interfaced with outlets 2, provides for the unloading of bulk material through two equal parts of the outlet channel 14 with a filled stream and ensures high quality separation of the flow of bulk materials. The control action from the accumulation of bulk material in the movable stabilizing tank 1 has no size limitations and thereby provides an expansion of the self-regulation zone when it interacts with the fixed slide wall 4. The design of the proposed device for separating the flow of bulk materials of the valves, the shaft inside the outlets, the mechanism valve rotation, significantly simplifies its design and provides an additional improvement in the quality of separation of the flow of bulk materials, due to eniya parts in the flow section.
