Each surface is provided with a limiting post 2, and the lower surface of the rotating ring disk is provided with a slot corresponding to the limiting post 2. Each slot is set in the radial direction of the rotating ring disk, and the limiting post 2 is located inside the corresponding slot, so that the opening and closing adjustment plate slides inward or outward of the rotating ring disk. Two limiting posts 3 are fixed on the upper surface of each opening and closing adjustment plate. The fixed ring disk is evenly provided with sliding grooves that are inclined inward. Each sliding groove corresponds to the limiting post 3 on each opening and closing adjustment plate. The two limiting posts 3 on each opening and closing adjustment plate are located in the corresponding sliding groove.

[0005] Furthermore, the rotating ring disk has a feeding pipe at the lower end of the central opening, and the lower surface of the rotating ring disk is uniformly marked with scales, and the side of the rotating ring disk is provided with an integrally connected actuating plate.

[0006] Furthermore, the lower end of the hopper has a conical structure, and the hopper and the fixed ring disc are integrally connected.

[0007] Furthermore, an upper mounting plate is provided on the outer side of the hopper, and mounting through holes are evenly provided on the upper mounting plate. The upper end of the device can be installed through the upper mounting plate, making installation more convenient.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: by rotating the rotating ring disk, the opening and closing adjustment plate is driven to move. The opening and closing adjustment plate can slide along the slide groove through the limiting column three, so that the opening and closing adjustment plate slides to the inside or outside of the rotating ring disk, thereby controlling the size of the opening in the middle of the opening and closing adjustment plate, thereby controlling the size of the feed inlet of the device, thus facilitating the control of the feeding speed. This screening equipment uses an adjustable feed inlet, has a simple structure, and is easy to operate. Not only is the device easier to install, but the size of the feed inlet can also be easily adjusted, making the feeding of the screening equipment more uniform and easier to use.
