[0004] The utility model adopts the technical scheme that

[0005] A shovel coal plate subassembly that can automatically clear coal mainly comprises a shovel coal plate subassembly, an upper hydraulic cylinder, a side hydraulic cylinder, a left connecting plate, a right connecting plate, a left coal cleaning plate and a right coal cleaning plate. The upper hydraulic cylinder and the side hydraulic cylinder are arranged on the upper surface and the side surface of the shovel coal plate subassembly respectively. The cylinder bottom of the upper hydraulic cylinder arranged on the upper surface of the shovel coal plate subassembly is fixed on the shovel coal plate subassembly through a pin shaft, and the cylinder rod is fixed on the left connecting plate through a pin shaft; the left connecting plate is connected to the left coal cleaning plate through bolts through the strip-shaped guide groove of the shovel coal plate subassembly. The cylinder bottom of the side hydraulic cylinder arranged on the side surface of the shovel coal plate subassembly is fixed on the shovel coal plate subassembly through a pin shaft, and the cylinder rod is fixed on the right connecting plate through a pin shaft; the right connecting plate is connected to the right coal cleaning plate through bolts through the strip-shaped guide groove of the shovel coal plate subassembly.

[0006] When no coal cleaning operation is performed, both hydraulic cylinders are in the retracted state, and the left coal cleaning plate and the right coal cleaning plate are in the middle position of the shovel coal plate and are tightly attached together.

[0007] The upper hydraulic cylinder and the side hydraulic cylinder are simultaneously extended and retracted, the left coal cleaning plate is guided to complete reciprocating movement through the left connecting plate, the U-shaped guide rail and the strip-shaped guide groove, and the right coal cleaning plate is guided to complete reciprocating movement through the right connecting plate, the U-shaped guide rail and the strip-shaped guide groove, so that the utility model completes a coal cleaning operation.

[0008] The beneficial effects of the utility model lie in:

[0009] The accumulated coal in the coal shovel plate can be rapidly removed by the utility model, the labor intensity of workers is reduced, and the labor cost is saved.

[0010] The accumulated coal on the coal wall side of the coal shovel plate can be completely removed, the accumulated coal can be prevented from cutting the conveyor belt and blocking the running channel of the conveyor belt, and the use performance of the self-moving tail of the belt conveyor is improved.

DETAILED DESCRIPTION

[0017] As shown in Figure 1 , 2 , 3, 4, 5, a coal shovel plate assembly capable of automatically removing coal mainly comprises a coal shovel plate assembly 1, a pin shaft 2, an upper hydraulic cylinder 3, a left coal removal plate 4, a right coal removal plate 5, a left connecting plate 6, a right connecting plate 7, and a side hydraulic cylinder 8; the coal shovel plate assembly 1 mainly comprises a U-shaped guide rail 11, a strip-shaped guide groove 12, and a coal shovel plate 13.

[0018] In the actual assembly process, the bottom of the upper hydraulic cylinder 3 is fixed on the coal shoveling plate assembly 1 through the pin shaft 2, and the cylinder rod is fixed on the left connecting plate 6 through the pin shaft 2; the left connecting plate 6 is bolted together with the left coal cleaning plate 4 through the strip-shaped guide groove 12 of the coal shoveling plate assembly 1. The bottom of the side hydraulic cylinder 8 is fixed on the coal shoveling plate assembly 1 through the pin shaft 2, and the cylinder rod is fixed on the right connecting plate 1 through the pin shaft 2; the right connecting plate 7 is bolted together with the right coal cleaning plate 5 through the strip-shaped guide groove 12 of the coal shoveling plate assembly 1. The utility model is coupled with the tail end frame 10 of the self-moving tail of the belt conveyor through the square head bolt, the bolt head height of the square head bolt is lower than the height of the sink hole of the coal shoveling plate 13, so as to ensure the smooth operation of the left and right coal cleaning plates 4 and 5.
