When the bottom plate 4 rotates to abut against the guide plate 24, the bottom plate 4 is aligned with the discharge hole 10, and the guide plate 24 plays a role in limiting the rotation angle of the bottom plate 4 on one hand, so that the bottom plate 4 is aligned with the discharge hole 10; on the other hand, the gap between the rotating bottom plate 4 and the outer barrel 1 can be filled, and the leakage of materials from the gap between the bottom plate 4 and the outer barrel 1 is avoided. First baffle plates 25 are fixed at the front end and the rear end of the guide plate 24, second baffle plates 26 are fixed at the front end and the rear end of the bottom plate 4, and the two second baffle plates 26 are located between the two first baffle plates 25. The first baffle 25 and the second baffle 26 respectively play a role in limiting the separation of the materials from the guide plate 24 and the bottom plate 4, and the materials are prevented from leaking into the outer barrel 1.

As shown in fig. 1 and 2, a gasket 8 made of a rubber material is fixed to the lower end surface of the cylinder 3. When the bottom plate 4 is tightly abutted to the cylinder 3 under the action of the driving cylinder 14, the sealing gasket 8 is extruded by the bottom plate 4 to deform and fill the gap between the bottom plate 4 and the cylinder 3, so that the phenomenon that the oil in the material directly flows onto the rotary table 12 from the gap between the bottom plate 4 and the cylinder 3 to influence the balance of the rotary table 12 is avoided.

The working principle of the embodiment is as follows: when discharging, the rotating speed of the variable frequency motor 9 is reduced to drive the bottom plate 4 to rotate slowly, and then the limiting rod 21 is pushed to one side close to the bottom plate 4. When the bottom plate 4 rotates to abut against the limiting rod 21, the bottom plate 4 is blocked by the limiting rod 21 and cannot rotate continuously, and then the variable frequency motor 9 is turned off. The bottom plate 4 is then driven by the driving cylinder 14 to rotate downwards until the bottom plate 4 abuts against the guide plate 24, at which time the material moves along the bottom plate 4 and the guide plate 24 under the action of gravity and moves out of the outer cylinder 1 through the discharge port 10 to achieve discharge. People need not to invert the oil removing cylinder 2 when taking out the materials, and the device has the effects of labor saving and convenience.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification, equivalent replacement, or improvement made within the design concept of the present invention should be included within the protection scope of the present invention.
