The lower horizontal surface of the pressing plate 7611 and the lower horizontal surface of the U-shaped plate 754 are on the same horizontal plane. When piercing a large volume of coal, the reciprocating block 758 drives the metal plate 7511 to move back and forth, and the metal plate 7511 hits the metal block 763, generating vibration, so that the coal ash adhering to the pressing plate 7611 is cleaned.

[0024] Working principle: When in use, place the coal on the conveyor belt 3 to transport the coal, then control the hydraulic cylinder 6 to drive the lifting plate 72 to descend, and the lifting plate 72 drives the scattered spikes 755 on the U-shaped plate 754 to descend, making it convenient to pierce large volumes of coal. At the same time, the lifting plate 72 drives the gear part 2 7522 to descend, and under the action of the tooth plate 71, the gear part 2 7522 is controlled to drive the gear part 1 7520 to rotate, and the rotating rod 1 7518 and the bevel gear 2 75 23. Under the action of bevel gear 1 7517, the rotating shaft 7512 is controlled to rotate, and the rotating shaft 7512 drives the rotating plate 7513 to rotate. The rotating plate 7513 drives the inclined plate 2 7514 to rotate. The inclined plate 2 7514 drives the reciprocating block 758 on the L-shaped plate 7516 to move. Under the action of inclined plate 1 756 and top plate 753, the U-shaped plates 754 on both sides are controlled to move toward each other repeatedly. The U-shaped plates 754 drive the dispersion spikes 755 to move toward each other repeatedly, so that the large volume of coal can be quickly The coal is punctured into small pieces to facilitate flattening at the back. At the same time, the lifting plate 72 drives the side plate 761 to descend, and the side plate 761 drives the connecting plate 762 to descend, and the connecting plate 762 drives the pressing plate 7611 to descend, making it easier for the pressing plate 7611 to press down the coal. At the same time, the U-shaped plate 754 drives the reciprocating plate 764 to move. Under the action of the control plate 765, the moving plate 769, and the connecting rod 7610, the pressing plate 7611 is controlled to move back and forth. At the same time, the reciprocating block 758 drives the metal plate 7511 to collide with the metal block 763, generating vibration, thereby increasing the flattening effect and cleaning the coal ash adhered to the pressing plate 7611. The metal blocks 763 are distributed on both sides of the connecting plate 762. The vibrations generated by the collision of the metals can be transmitted to the pressing plate 7611 on the lower side. This vibration causes the coal particles to produce high-frequency micro-displacements, breaking the "locked" state of static friction, reducing the shear resistance between the particles, and increasing the flattening effect.
