The crushing cavity in the embodiment comprises at least two processing cavities, specifically two processing cavities, the processing cavities are arranged in a diagonal manner from top to bottom left, and the adjacent processing cavities are communicated with each other; each processing chamber is internally provided with a crushing hammer.

A plurality of metal anti-collision plates, preferably iron plates, are distributed on the inner wall of the whole crushing cavity, honeycomb-shaped holes are formed in the anti-collision plates, and a rubber damping layer is arranged between the anti-collision plates and the inner wall of the crushing cavity; the mounting holes 9 shown in figure 1 are formed in the wall of each of the anti-collision plate, the rubber shock-absorbing layer and the crushing cavity, so that the anti-collision plate and the rubber shock-absorbing layer can be conveniently mounted on the inner wall of the crushing cavity by adopting nut screws.

The specific implementation process is as follows:

the first reinforcing ribs 5 in the scheme can support the chain wheel, and the chain wheel is always in contact with the balls 52; in the process of the rotation of the chain wheel, the friction between the chain wheel and the ball 52 is small under the action of lubricating oil. In addition, the balls 52 are always in contact with the oil absorption layer 53 in the rotating process, so that lubricating oil can be excessively applied to the chain wheel, and the chain wheel is further prevented from rusting and the like; excess lubricating oil can flow back into the oil gallery from the oil return pipe 54; further, if it is necessary to add lubricating oil, it may be injected from the oil return pipe 54.

Example two:

on the basis of the first embodiment, the main differences of the present embodiment are as follows: as shown in fig. 4 and 5, the supporting seat 7 includes a seat body and a supporting rod 71 for supporting the case cover 41, a sliding cavity is provided in the seat body, and the supporting rod 71 is slidably connected to a cavity wall of the sliding cavity; an air cavity 712 communicated with the sliding cavity is arranged in the box body 4, an air vent pipe communicated with the outside is communicated on the air cavity 712, a piston 713 is connected in the air cavity 712 in a sliding mode, and the piston 713 is fixedly connected with the supporting rod 71.

When the box cover 41 needs to be opened, the supporting rod 71 can be pulled upwards, so that the supporting rod 71 can support the box cover 41 earlier; at this time, a person can release the cover 41, and the cover 41 moves downward slowly under the action of the support rod 71 and the piston 713, so that the trouble that the cover 41 needs to be dragged by the person when the cover 41 moves downward after being opened is avoided.

Example three:

on the basis of the first embodiment, as shown in fig. 6 and 7, a baffle 2 is arranged below the feed inlet 1, a rotating shaft is arranged on the right side of the baffle 2, a rotating groove is arranged on the inner wall of the crushing cavity, and the rotating shaft is rotatably connected with the rotating groove. The rotation junction is provided with and is used for baffle 2 to reset and cover the reset spring of feed inlet 1, and the reset spring in this embodiment is the torsional spring, and the principle that the torsional spring resets is prior art, and here is no longer repeated.

The baffle 2 is provided with a plurality of positioning grooves 21, and the positioning grooves 21 are internally provided with movable layers formed by mutually hinging a plurality of metal strips 211, and it is worth mentioning that the metal strips 211 in the embodiment have mutually hinged long sides; the metal strip 211 can be steel strip, iron bar, etc., and the steel strip is specifically got to this embodiment. The long edges of the metal strips 211 at the two sides of the active layer are respectively hinged with the groove walls at the two sides of the positioning groove 21.
