And through the cooperation relationship between the inner wall of the grinding disc 37 and the discharging tray 33, the coal blocks passing through the discharging holes 34 can be ground. Then the refined coal blocks after grinding will be discharged into the ignition driving assembly 4 through the guiding pipe 39.

[0068] The push rod 524 is installed on the blanking and grinding assembly 3, and the push rod 524 cooperates with the push frame 523.

[0069] During use, the movement of the grinding disc 37 will control the push frame 523 to move left and right reciprocally through the push rod 524, thereby driving the slider 521 to move synchronously. At the same time, the double-direction elastic telescopic rod 519 will drive the control frame 514 to move reciprocally, so as to switch the cooperation relationship between the fourth bevel gear 517 and the fifth bevel gear 518 and the third bevel gear 512.

[0070] Start the control motor 515, then the control motor 515 will drive the control shaft 516 to rotate, and drive the fourth bevel gear 517 and the fifth bevel gear 518 to rotate. And when the fourth bevel gear 517 and the fifth bevel gear 518 cooperate with the third bevel gear 512 respectively, the third bevel gear 512 will rotate in opposite directions.
