A top plate 11 is installed at the upper end of the support columns 10, a first hydraulic cylinder 14 is installed at the upper end of the top plate 11, the output end of the first hydraulic cylinder 14 penetrates and extends to the lower end of the top plate 11, and a pressing block 12 is installed.

[0029] Please refer to Figure 1 , the output end of the second hydraulic cylinder 18 is in transmission connection with the first moving jaw plate 5. When feeding, if material jamming occurs at the material inlet, the first moving jaw plate 5 can be controlled by the second hydraulic cylinder 18 to reciprocate slightly, cooperate with the second moving jaw plate 9 that is eccentrically moving, and extrude the upper material to facilitate the broken material to fall.

[0030] Please refer to Figure 1 , an inner cutting surface 13 is provided at the rear end of the pressing block 12, and the inner cutting surface 13 of the pressing block 12 matches the inclination angle of the second moving jaw plate 9, which is convenient for the first hydraulic cylinder 14 to control its downward movement to extrude the material at the material inlet.

The reinforcing plates 3 improve the connection strength between the machine housing 1 and the support seats 2 and ensure the bearing capacity of the support seats 2.

[0033] Working principle: During use, the material is poured from the material inlet. The second moving jaw plate 9 reciprocates under the action of the eccentric shaft and cooperates with the first moving jaw plate 5 and the stationary jaw plate 19 to realize the extrusion and crushing of the material. When jamming occurs at the material inlet, the first hydraulic cylinder 14 and the second hydraulic cylinder 18 can be driven to operate. The first hydraulic cylinder 14 controls the downward movement of the briquetting block 12 to apply a certain downward pressure to the material at the material inlet, while the second hydraulic cylinder 18 controls the reciprocating micro-movement of the first moving jaw plate 5, which cooperates with the second moving jaw plate 9 with eccentric movement to apply double-sided pressure to the material from the material inlet to facilitate the crushing and discharging of the material, thereby preventing the occurrence of jamming.
