Illustratively, taking the case that the baffle 2 is fixed to the lower housing 15 as shown in fig. 6, a surface of the lower housing 15 facing the upper housing 14 (i.e., a surface of the lower housing 15 near the discharge bin 112) is provided with a fixing groove 151, and the baffle 2 is fixed in the fixing groove 151. Thus, the baffle plate 2 is limited by the fixing groove 151, so that the baffle plate 2 is conveniently positioned in advance, and the assembly efficiency of the baffle plate 2 is conveniently improved. Of course, in combination with the above-mentioned case that the crushing bin 11 has a cylindrical inner cavity, the baffle 2 may also be supported on the inner wall of the discharge bin 112 and fixed, which is not limited in the embodiment of the present application.

Optionally, when the cutter 32 is screwed into the cutting slit 21, it can be attached to the side surface of the cutting slit 21, so as to further improve the crushing effect on the material.

In the present embodiment, the cutter shaft 31 may be located on the side of the baffle 2 close to the feeding bin 111 or on the side close to the discharging bin 112, as long as the cutter 32 can be screwed into or out of the cutting slit 21 when rotating, which is not limited in the present embodiment.

In some embodiments, as shown in fig. 9, a plurality of cutters 32 are helically distributed along the arbor 31. In this way, when the plurality of cutters 32 cut the material, the load of the driving mechanism 4 can be ensured to be basically stable, and the situation that the instantaneous load of the driving mechanism 4 is large is avoided, so as to ensure the running stability of the material crushing device 10.

Wherein, as shown in fig. 10, the plurality of cutters 32 are uniformly distributed in the circumferential direction of the cutter shaft 31 to further secure the stability of the load of the driving mechanism 4.

In some embodiments, as shown in fig. 9 or 10, the cutter 32 has a cutter hook 321 at an end remote from the cutter shaft 31, and the cutting edge of the cutter 32 is formed inside the cutter hook 321. So, through the setting of knife hook 321, when cutter 32 is rotatory, can avoid the circumstances that skids between material and the cutter 32 through knife hook 321 card owner material, and then guarantee the cutting effect of cutter 32 to the material.

Of course, the cutter 32 may have other structures to ensure the cutting effect on the material. For example, the cutter 32 is an arc mechanism, and the blade of the cutter 32 is formed inside the arc mechanism. So, when the cutter 32 of arc structure rotates, can block the main material equally, avoid the condition that skids between material and the cutter 32.
