It should be noted that, in this embodiment, the bottom wall of the inner cavity of the case 20 is obliquely disposed and obliquely faces downward toward the discharge port 22, so as to discharge the crushed gypsum filtered by the screen plate 60.

The cutting mechanism 30, the crushing mechanism 40 and the fishing assembly 50 are sequentially and longitudinally arranged in the box 20, wherein the fishing assembly 50 can comprise two filtering mechanisms 51 and a fishing mechanism 52.

Wherein, two filtering mechanisms 51 are disposed obliquely downward below the pulverizing mechanism 40 in sequence, and the two filtering mechanisms 51 are fixedly connected with two side inner walls of the case 20, wherein one filtering mechanism 51 (i.e. the filtering mechanism 51 located at the lowest position) is disposed near the bottom opening of the impurity discharging opening 23, and the filtering mechanism 51 is used for intercepting the facing paper salvaged by the salvaging mechanism 52 and discharging the facing paper through the impurity discharging opening 23, and the other filtering mechanism is mainly used for intercepting the facing paper in the gypsum board after being pulverized by the pulverizing mechanism 40.

The salvaging mechanism 52 is rotatably provided between the two filtering mechanisms 51, and the salvaging mechanism 52 is respectively engaged with the two filtering mechanisms 51.

The screen 60 is disposed obliquely upward below the salvaging mechanism 52, and the screen 60 is detachably connected to the case 20. It will be appreciated that the screen panels 60 described in this embodiment are removably attached to the housing 20 to facilitate installation and replacement of the screen panels 60. For example, screen panel 60 may be connected to housing 20 by a snap fit connection. That is, by providing a clamping groove (not specifically identified in the figure) on the box 20, the screen plate 60 is clamped on the box 20 through the clamping groove.

Specifically, when the waste gypsum board to be crushed is required to be crushed, the relevant staff first needs to set the waste gypsum board crushing and recycling apparatus at the position of the waste gypsum board to be crushed (which may be in a processing plant of the waste gypsum board), and then the staff controls the conveying apparatus (belt conveyor) to convey the waste gypsum board to be crushed into the box 20 through the feed inlet 21. At this time, the worker controls the driving unit 70 to drive the cutting mechanism 30, the crushing mechanism 40 and the salvaging mechanism 52 to perform the synchronous movement, and the waste gypsum board entering the box 20 is cut into a plurality of lath-shaped gypsum boards by the cutting mechanism 30, and then the lath-shaped gypsum boards are crushed by the crushing mechanism 40, so that the crushed gypsum is separated from the strip-shaped facing paper.

Along with this, the crushed gypsum and the strip-shaped facing paper fall onto the filter mechanism 51, wherein the crushed gypsum falls directly onto the screen plate 60 through the filter mechanism 51, is filtered to the bottom of the inner cavity of the box body 20 through the screen plate 60, and is finally discharged through the discharge port 22. And the gypsum filtered on the screen 60, which is not completely crushed, enters the lifting device 80 through the screen 60. At this time, the worker controls the lifting device 80 to lift the gypsum that is not completely crushed to the crushing mechanism 40 to continue crushing, and circulates in this way until the crushed gypsum is screened to the bottom of the inner cavity of the case 20 by the screen plate 60. Thereby ensuring that the size of the crushed gypsum particles is uniform so as to improve the quality of the finished product of the gypsum board.

The strip-shaped facial tissues are filtered on the filtering mechanism 51, and the fishing mechanism 52 is used for fishing out the strip-shaped facial tissues on the filtering mechanism 51 and discharging the strip-shaped facial tissues through the impurity discharging port 23 on the box body 20, so that the effective screening of the facial tissues and gypsum is realized, and the paper scraps of the facial tissues are prevented from entering the formed gypsum board, thereby effectively improving the yield of the gypsum board.

Similarly, the two pulverizing rollers 42 are rotated in opposite directions. The rotating second supporting shaft 521 drives the plurality of groups of salvaging claws 522 to rotate so as to salvage the strip-shaped facing paper.

In one embodiment of the present utility model, as shown in fig. 1 and 4, the lifting device 80 may include a cylinder 81, a third support shaft 82, a helical blade 83, and a second driving mechanism 84.
