[0016] (Three) beneficial effects

[0017] Compared with the prior art, the utility model provides the pipe chain conveyor with the unloading valve, and has the following beneficial effects:

[0018] 1. The arc-shaped plate and the first sealing gasket are moved by an electric cylinder, moving along the axial direction of the pipeline to adjust the size of the discharge port. The discharge flow rate is adjusted by adjusting the size of the discharge port opening, ensuring that the material inside the pipeline falls directly from the discharge port opening. At the same time, the electric cylinder pushes the arc-shaped plate and the first sealing gasket to seal the discharge port, which can prevent material from getting stuck between the pipeline, the arc-shaped plate and the first sealing gasket, and facilitate complete sealing of the discharge port, thus improving its practicality.

[0019] 2. By rotating the screw counterclockwise, the screw causes the convex seat to slide upward inside the convex groove. The convex seat drives the arc plate and the first sealing gasket to move upward. By adjusting the height of the arc plate and the first sealing gasket, the squeezing force between the first sealing gasket and the pipe can be adjusted, which facilitates the adjustment of the sealing performance between the first sealing gasket and the pipe and can ensure the sealing effect of the discharge port.

[0020] 3. Unscrew the first screws to remove the mounting plate. Then, pull the screw, convex seat and arc plate downwards through the mounting plate and the shaft to facilitate the removal of the arc plate and the replacement of the first sealing gasket. Attached Figure Description
