The sliders 72 are slidably connected to the three arc-shaped slide bars 71 on the front and rear sides. The first return springs 73 are mounted on the three arc-shaped slide bars 71 on the front and rear sides. One end of the three first return springs 73 on the front and rear sides is respectively connected to the three sliders 72 on the front and rear sides, and the other end of the three first return springs 73 on the front and rear sides is connected to the The material pressing shell 4 is connected, a connecting plate 74 is fixedly connected between the inner sides of the three front sliders 72, a connecting plate 74 is also fixedly connected between the inner sides of the three rear sliders 72, a rotating ring 75 is fixedly connected between the outer sides of the front and rear sliders 72 on the top, a rotating ring 75 is also fixedly connected between the outer sides of the front and rear sliders 72 on the middle, and a rotating ring 75 is also fixedly connected between the outer sides of the front and rear sliders 72 on the bottom. The outer sides of the three rotating rings 75 are fixedly connected with protrusions 76 at intervals. The protrusions 76 can increase the contact area with the gypsum, so that the up and down movement of the protrusions 76 can achieve more thorough gypsum crushing.

[0040] like Figure 2 , Figure 8 and Fig. 9As shown, it also includes a rotating mechanism 8, which includes a mounting frame 81, a ratchet 82, a fixing plate 83, a ratchet bar 84, a second return spring 85, a fixing seat 86, a rotating shaft 87, a bevel gear 88, a winding drum 89 and a pull rope 810. The front and rear side surfaces of the pressing shell 4 are fixedly connected with the mounting frame 81, and the middle parts of the front and rear mounting frames 81 are rotatably connected with the ratchet 82.

[0041] When the motor 65 is working, the pressing shell 4 moves up and down, driving the six sliders 72 to move up and down. The six sliders 72 move up and down and respectively drive the three rotating rings 75 to move up and down. The three rotating rings 75 move up and down and respectively move the protrusions 76 up and down. The protrusions 76 move up and down and contact the gypsum. The protrusions 76 can increase the contact area with the gypsum, so that the up and down movement of the protrusions 76 can achieve more thorough crushing of the gypsum. After the gypsum is crushed, the motor 65 is turned off, and the pressing shell 4 stops driving the three rotating rings 75 up and down through the six sliders 72, and the protrusions 76 also stop moving up and down. In this way, the contact area with the gypsum can be increased, and the crushing is more thorough.

Due to the action of the second return springs 85 on the left and right sides, the left and right ratchet wheels 82 move upward and slide over the left and right ratchet bars 84 respectively. Then the downward movement of the pressing shell 4 drives the left and right mounting frames 81 to move downward, and the downward movement of the left and right mounting frames 81 respectively drives the left and right ratchet wheels 82 to move downward, and the left and right ratchet wheels 82 move downward and start to rotate respectively through the left and right ratchet bars 84, and the rotation of the left and right ratchet wheels 82 respectively drives the left and right rotating shafts 87 to rotate through the two bevel gears 88 on the left and right sides, and the rotation of the left and right rotating shafts 87 respectively drives the left and right The side winding drum 89 rotates, and the left and right winding drums 89 rotate and respectively drive the front and rear connecting plates 74 to rotate forward through the left and right pull ropes 810, and the six first return springs 73 are all compressed. The front and rear connecting plates 74 rotate forward and respectively drive the three sliders 72 on the front and rear sides to rotate forward, and the three sliders 72 on the front and rear sides rotate forward and respectively drive the three rotating rings 75 to rotate, and the rotation of the three rotating rings 75 drives the protrusions 76 to rotate forward, and the protrusions 76 rotate forward to further crush the gypsum, and then the ratchet 82 moves downward and continues to move downward to disengage from the left and right ratchet strips 84 respectively. Due to the action of the six first return springs 73, the front and rear connecting plates 74 respectively drive the three sliders 72 on the front and rear sides to reverse and reset, and the protrusions 76 also reverse and reset, so that the gypsum can be further crushed.

The hooks 102 can be used to facilitate people to place items.

[0046] First, the operator pulls the pull rod 93 to move upward, the third return spring 94 is compressed, the pull rod 93 moves upward and disengages from the left and right baffle plates 51, then pulls the rotary lock rod 54 to rotate 180 degrees, and then pulls the curved door panel 53 downward through the pull rod 93, then puts an appropriate amount of gypsum into the installation bucket 2, and again pulls the curved door panel 53 upward and swings back to its original position through the pull rod 93, releases the pull rod 93, and due to the action of the third return spring 94, the pull rod 93 moves downward and is stuck between the left and right baffle plates 51, and then pulls the rotary lock rod 54 to rotate 180 degrees. In this way, it is convenient for people to pull the curved door panel 53.
