[0043] Specifically in this application, a receiving cavity is arranged on the gate plate 200. An installation opening is arranged on the end surface of one end of the gate plate 200 facing the abutting block 110. The installation opening is communicated with the receiving cavity. The extrusion block 500 is movably arranged in the installation opening. The second driving device 600 is arranged in the receiving cavity to drive the extrusion block 500 to contract or extend out of the installation opening.

The driving blocks 630 are fixedly arranged on two adjacent cushion blocks 631 to improve the stability of the driving blocks 630 fixed on the rotating shaft 610. At the same time, it is also convenient to adjust the distance between the driving blocks 630 and the extrusion blocks 500, so as to adjust the distance that the extrusion blocks 500 extend out of the installation opening and improve the adjustment ability of the coal bunker gate.

[0046] In a specific embodiment of the present application, an installation block 510 is arranged on the side wall of the extrusion block 500. A first elastic member 520 is arranged between the installation block 510 and the gate plate 200. One end of the first elastic member 520 is fixedly connected to the installation block 510, and the other end of the first elastic member 520 is fixedly connected to the gate plate 200. The first elastic member 520 is used to provide an elastic force for the installation block 510 to shrink back into the installation opening. Through the above arrangement, when the driving block 630 drives the extrusion block 500 to move towards the abutting block 110, the installation block 510 can overcome the elastic force of the first elastic member 520. When the driving block 630 rotates past the extrusion block 500 and no longer abuts against the extrusion block 500, the first elastic member 520 can drive the extrusion block 500 to retract into the installation opening, so as to realize the reciprocating movement of the extrusion block 500 relative to the extrusion block 500.

[0047] In other feasible embodiments of the present application, the extrusion block 500 can be connected to the second driving device 600 through a link structure to realize the reciprocating movement of the extrusion block 500.

[0048] In a specific embodiment of the present application, the driving member 620 includes a driving motor 621, a first gear 622, a second gear 623, and a chain 624. The driving motor 621 is fixedly arranged on the support plate 670. A first gear 622 is arranged at the output end of the driving motor 621. The second gear 623 is fixedly arranged on the rotating shaft 610. The chain 624 is sleeved between the first gear 622 and the second gear 623. The driving motor 621 drives the first gear 622 to rotate, and drives the second gear 623 and the rotating shaft 610 to rotate through the chain, thereby achieving the driving effect of the driving member 620.

[0049] Specifically, a plurality of driving members 620 may be provided, thereby improving the driving effect of the second driving device 600.

[0050] In other embodiments of the present application, the driving member 620 may also only include the driving motor 621, and the driving motors 621 are respectively arranged at both ends of the rotating shaft 610 to improve the driving effect of the second driving device 600.

[0051] Specifically in the present application, the second driving device 600 further includes support blocks 640, telescopic tubes 650, and second elastic members 660. Among them, there are two support blocks 640, and the two support blocks 640 are respectively arranged at both ends of the rotating shaft 610.

The second elastic member 660 is sleeved on the telescopic tube 650, and the second elastic member 660 is used to buffer the movement of the support block 640. Through the above arrangement, when the driving block 630 drives the extrusion block 500 to move towards the abutting block 110, due to the reverse acting force of the extrusion block 500, the driving block 630 will drive the rotating shaft 610 to move under the action of the extrusion block 500. In this way, the support block 640 will squeeze the telescopic tube 650 and the second elastic member 660, and the second elastic member 660 can buffer the rotating shaft 610, preventing a large resistance from being caused to the rotation of the rotating shaft 610, thereby improving the driving effect and durability of the second driving device 600.

Through the above arrangement, the fitting blocks 120 can cooperate with the extrusion block 500 to crush the coal material from both sides of the coal material, improving the crushing effect. And by setting an interval between the fitting blocks 120 and the extrusion block 500 in the height direction, the discharging efficiency of the crushed coal material can be improved, preventing the coal material that has been crushed from getting stuck at the gate 400 again.

[0056] Furthermore, a plurality of receiving grooves 130 are arranged on the abutting block 110.
