[0036] The discharging port in the utility model is also called the discharge port, for example, the left discharging port is called the left discharge port, and the right discharging port is called the right discharge port.

[0037] The technical advantages of the utility model are as follows:

[0038] ①The hydraulic cylinder 3 drives the valve plate 4 to move between the rollers 5, and realizes the "right discharging", "closing" and "left discharging" actions; only the friction between the rollers 5 and the valve plate 4 and the friction between the valve plate 4 and the material need to be overcome in the action process, the gravity of the material in the bin does not need to be overcome, the action load is small; at the same time, no matter which discharge port is closed or both discharge ports are closed, the gravity of the material in the upper bin of the closed discharge port is transmitted to the roller by the valve plate, and the additional power provided by the driving mechanism hydraulic cylinder of the valve itself is not needed, even if the power of the hydraulic cylinder is interrupted, as long as the oil pressure in the hydraulic cylinder is locked, the valve will not be misoperated, which is energy-saving, safe and reliable.

[0039] ②The distributor is inclined to the horizontal plane at an angle "a", the angle is greater than the repose angle of the material, the valve plate and the roller are prevented from storing the material, and the lower cavity of the valve is also prevented from storing the material after the valve is closed, and the jamming during the opening and closing of the valve is avoided to the maximum extent.

[0040] ③The left and right discharge ports of the valve plate 4 are appropriately smaller than the width of the valve plate, the roller 5 is appropriately away from the discharge port, the influence of the material flow on the roller during the action of the distributor is reduced, and the jamming is reduced as much as possible.

[0041] ④The areas of the bottom and the side wall of the distributor shell 2, the middle partition plate and the like which are in contact with the material are all provided with wear-resistant lining plates 6, and the valve plate 4 itself is made of wear-resistant material, so that the shell and the valve plate are prevented from being worn too fast, and the service life of the equipment is prolonged.

[0043] ⑥Each column of rollers 5 is arranged in a staggered manner along the upper and lower surfaces of the valve plate, which can limit the displacement of the valve plate 4 perpendicular to the surface during movement, and the valve plate 4 runs more stably.

[0044] ⑦The front end of the distributor shell 2 is provided with two blowing gas interfaces 21 and 22, as shown in Figure 5As shown, purge gas can be introduced to periodically purge the valve plate, roller, track and other parts. If the material has a high water content, high temperature gas can also be introduced, which has the following three aspects: 1) drying and ash removal of the internal cavity of the valve, especially the valve plate and roller; 2) by maintaining a certain temperature in the cavity, condensation in the cavity can be prevented, and powder ash adhesion can be reduced. 3) In winter or other low temperature conditions, through high temperature gas drying and heating, internal icing and freezing can be prevented. The maximum degree of equipment operation reliability is ensured.
