[0030] Reference Figure 4The screening box 8 has a discharge port 26 on the right side. A baffle 27 is slidably connected inside the screening box 8. The top of the baffle 27 extends to the top of the screening box 8. A fixing block 28 is fixedly connected to the top of the screening box 8. A bolt 29 is threaded inside the fixing block 28. A slot is provided on the right side of the baffle 27. The bolt 29 is inserted into the slot. The fixing block 28 fits against the baffle 27.

[0031] As a technical optimization of this utility model, by setting up the discharge port 26, baffle 27, fixing block 28, bolt 29 and slot, when the operator needs to disassemble the baffle 27, the operator first disassembles the bolt 29, so that the bolt 29 is separated from the slot, thereby releasing the lock on the baffle 27.

[0032] The working principle and usage process of this utility model are as follows: During use, the material first passes through the crushing box 3 for the first stage of crushing, and then passes through the grinding box 2 for the second stage of crushing. The crushed material falls into the screening box 8. The movable rod 9 slides back and forth in the chute, which allows the drive frame 10 to slide back and forth stably. At this time, the first motor 11 rotates, driving the disc 12 to rotate, which in turn drives the drive rod 13 to move back and forth, which in turn drives the drive frame 10 to move back and forth. The drive frame 10 drives the screening box 8 and the slide rail 7 to move back and forth. The slide rail 7 slides back and forth on the surface of the T-shaped slide bar 6. The screening box 8 moves back and forth, thereby improving the screening efficiency of the screening box 8. Small volume materials pass through the filter holes and fall into the storage box below the screening box 8. Large volume materials accumulate inside the screening box 8. When too much large volume material accumulates in the screening box 8, the operator can clean the material in the screening box 8.

[0033] When the operator needs to discharge the large volume material accumulated in the screening box 8, the operator first removes the baffle 27, then places the collection box on the right side of the support plate 4, and then starts the electric cylinder 22 to extend and drive the slider 23 to move to the right, which in turn drives the connecting rod 24 to move, which in turn drives the support frame 5 to rotate clockwise, which in turn drives the T-shaped slide bar 6, slide rail 7 and screening box 8 to rotate clockwise. At this time, the screening box 8 tilts, and the large volume material in the screening box 8 slides into the collection box, thus completing the collection of the large volume material filtered out in the screening box 8.

[0034] The surfaces of the first motor 11 and the disc 12 are provided with protective covers. The protective covers serve to protect the disc 12 and the first motor 11 from being damaged. The protective covers are common existing technology and are common knowledge to those skilled in the art, so they are not shown and will not be described in detail in this application. During crushing and screening, a dust collection device can be used in conjunction with the crushing and screening process. The dust collection device can handle the emitted smoke and dust. The dust collection device is common existing technology and will not be described in detail in this application.
