[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] Embodiment 1:

[0027] See also Figure 1-3 , the utility model provides a technical solution:

[0028] A wear-resistant and anti-clogging drainage valve comprises a pipe body 5, a valve plate 6, a connecting rod 1, and a rotating rod 11. The valve plate 6 is arranged inside the pipe body 5 for opening or closing the valve. A mounting frame 3 is arranged at the top of the pipe body 5. A bin 2 is installed at the top of the mounting frame 3 for connecting a driving structure. The driving structure is installed at one end of the connecting rod 1. The driving structure is used as an output power source to drive the valve.

[0029] The other end of the connecting rod 1 is extended to the interior of the warehouse body 2 and a helical toothed cylinder 1 9 is set, the top end of the rotating rod 11 is extended to the interior of the warehouse body 2 and a helical toothed cylinder 2 10 is set, and the helical toothed cylinder 1 9 is meshed with the helical toothed cylinder 2 10 to realize the transmission of the two horizontal and vertical rod bodies, thereby facilitating the opening and closing of the valve plate;

[0030] The bottom end of the rotating rod 11 is passed through the mounting frame 3 and rotatably connected to the bottom end of the tube body 5 to realize the rotation of the rotating rod 11 on the tube body 5. The rod body of the rotating rod 11 is fixed to the valve plate 6 to facilitate the rotation of the valve plate 6. In order to realize the wear resistance of the wear-resistant valve, a wear-resistant layer 61 is provided on the edge of the valve plate 6, and the wear-resistant layer 61 is a wear-resistant coating.

[0031] like Figure 1 As shown:

[0032] The top end of the tube body 5 is connected to the mounting frame 3 by bolts, which is convenient for disassembly and installation, simple and effective.

[0033] like Figure 1 As shown:

[0034] The driving structure is an automatic adjustment device, which is used in scenarios where the drainage size needs to be automatically adjusted. The automatic adjustment device includes a motor 102 and a reducer 103. The output end of the motor 102 is connected to the reducer 103, and the output end of the reducer 103 is connected to the connecting rod 1 through a coupling. Through the design of the motor 102 and the reducer 103, the connecting rod 1 can be automatically driven to rotate, thereby achieving the purpose of driving the rotating rod 11 and the valve plate 6 to automatically rotate, which is convenient for automatic control of the drainage size.

[0035] like Figure 3 As shown:

[0036] A bearing 8 is installed on one side of the silo body 2 so that the connecting rod 1 passes through the bearing 8 and has an interference fit with the bearing 8. The connecting rod 1 can rotate horizontally on the silo body 2 without affecting the use.

[0037] like Figure 3 As shown:

[0038] The wear-resistant coating is Teflon, which has excellent performance. It is a high-performance plastic material with excellent properties of wear resistance, high temperature resistance, corrosion resistance and low friction, which greatly improves the service life.

[0039] How it works:

[0040] Drive 102 to output power, and the reducer 103 drives the connecting rod 1 to rotate after deceleration. The helical cylinder 1 9 on the connecting rod 1 drives the rotating rod 11 to rotate through the helical cylinder 2 10 to realize the transmission function. At this time, the valve plate 6 rotates with the rotating rod 11, and the gap between the valve plate 6 and the inner wall of the pipe body 5 is exposed, which is convenient for drainage. The size of the exposed gap determines the drainage amount, which is convenient for adjustment.

[0041] Embodiment 2:

[0042] The difference from Example 1 is that the driving structure is a manual adjustment device, which is used in scenarios where energy needs to be saved or precise control of the drainage size is not required. The manual adjustment device includes a turntable 4 and a handle 101. The edge of the turntable 4 is welded to the handle 101, and eccentric rotation can be achieved when the handle 101 is rotated, which is convenient to use and saves effort. The center of one side of the turntable 4 is welded to the connecting rod 1 to drive the connecting rod 1 to rotate.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
