The box body and the drive motor 6 are both installed on a base 7. The shaft is arranged horizontally, and a driven pulley is fixed at one end. A driving pulley is fixed to the shaft of the drive motor 6, so that the rotation of the crushing shaft 4 is realized by a transmission belt.

[0023] The box body includes a lower box body 2 and an upper box body 1. The lower box body 2 is fixed on the base 7. The butt joint surface of the two boxes is a horizontal plane. One side of the upper box body 1 is hinged to the lower box body 2 through a hinge, so that the upper box body 1 can be flipped upward to open.

[0024] like Figure 7 As shown, the other side of the upper case 1 is connected to the lower case 2 via a detachable connector 3. The detachable connector 3 includes a screw 31 hinged to the side of the lower case 2 and a connecting plate 32 fixed to the side of the upper case 1. Two side-by-side mounting base plates 35 are fixed to the side of the lower case 2. A horizontal screw mounting shaft 34 is connected between the two mounting base plates 35. The screw mounting shaft 34 passes through one end of the screw 31, thereby realizing the hinge connection of the screw 31.

[0025] A screw receiving groove is provided on the side of the connecting plate 32 away from the upper box body 1. The screw 31 can be placed in the screw receiving groove after swinging upward. A nut 33 is installed on the screw 31. At this time, tightening the nut 33 to the upper end face of the connecting plate 32 can realize the connection between the upper box body 1 and the lower box body 2.

[0026] The box body is provided with a filter screen plate 17 located below the crushing assembly. The filter screen plate 17 is arc-shaped and the rotating outer circle of the crushing assembly is concentric with the filter screen plate 17, so that the crushed powder is screened out downward. The inner wall of the upper box body 1 is also arc-shaped. The inner wall of the box body is fixedly connected to a plurality of fixed crushing plates 16 located above the crushing assembly. The fixed crushing plates 16 are arranged circumferentially along the crushing shaft 4, thereby improving the crushing effect.

[0027] A powder collecting drawer 5 is provided on the side of the box body below the filter screen plate 17 for storing powder and can be drawn out to pour out the powder.

[0028] like Figure 5 、 6 As shown, the crushing assembly includes multiple discs 11 fixed side by side on the crushing shaft 4. The discs 11 are equipped with multiple mounting shafts 12 evenly distributed along the circumference of the crushing shaft 4. Each mounting shaft 12 passes through all the discs 11. The mounting shafts 12 and the discs 11 can be rotatably connected or fixedly connected.

[0029] A crushing connecting rod 13 is hinged on the installation shaft 12 . The installation shaft 12 passes through one end of the crushing connecting rod 13 . A crushing block 14 is fixed to the crushing connecting rod 13 .

[0030] In the present embodiment, four mounting shafts 12 are provided. Four limit stop shafts 15 are mounted on the disc 11 to limit the swing of the crushing connecting rod 13.

[0031] like Figure 4 As shown, the upper end of the box body is connected to a blanking box 8, and a feed port is opened on the blanking box 8. The feed port is arranged on the side of the blanking box 8, and a feed slant bucket 9 is fixed to the side of the blanking box 8. The bottom surface of the feed slant bucket 9 is an inclined surface and the lower end is connected to the lower end of the feed port.

[0032] The feed port is provided with a switch door 10, which can be closed when no material is needed to be added to prevent dust from floating out.

[0033] A horizontal balancing shaft 18 is connected to the blanking box 8, and downward-inclined balancing baffles 19 are fixed on both sides of the balancing shaft 18. The upper ends of the balancing baffles 19 are fixed to the balancing shaft 18, and the two balancing baffles 19 are symmetrically arranged so as to maintain a balanced state.

[0034] A guide plate 20 is fixedly connected to the inner wall of the blanking box 8 below the feed port, wherein the swinging path of one end of the balancing baffle 19 is tangent to the guide plate 20, and the swinging path of the other end of the balancing baffle 19 is tangent to the inner wall of the blanking box 8 on the other side.

[0035] The use method of this utility model:

[0036] During use, the block material is poured onto the feed hopper 9 and slides downward, entering the drop box 8 from the feed port. During the falling process, the balance baffle 19 is pushed open and enters the box body. The crushing assembly is driven to rotate by the motor, and the crushing block 14 rotates at high speed to impact and crush the material. The powder crushed to a specified size passes through the filter plate 17 below and enters the powder collection drawer 5. When the block material is stopped from being added, the balance baffle 19 maintains balance under the action of gravity, thereby preventing dust from flowing upward and thus unable to float out from the feed port.

[0037] When the interior of the box needs to be cleaned and repaired, the nut 33 is loosened, and the connecting screw 31 is swung out of the screw receiving groove, and the upper box 1 can be opened.
