[0033] Working principle: When the device is in use, the material to be crushed and screened is put into the main body 1 from the feed inlet for crushing. Then, the device operates to crush the material into small particles and flow into the screening box 3 for screening. By providing the conveying device 6, when the device is in use, during the screening process, the material that cannot pass through the sieve mesh 5 flows from the distribution port 4 into the feed hopper 62, and then the material flows from the feed hopper 62 into the material box 61. When the first motor 66 operates, it drives the first rotating rod 64 to rotate. Then, the first rotating rod 64 rotates to drive the spiral blade 65 to rotate. When the spiral blade 65 rotates, it drives the material to be conveyed upward through the conveying pipe. Then, when the material is conveyed to the top of the conveying pipe, it flows into the connecting pipe 69, and then the connecting pipe 69 flows into the main body 1 for secondary crushing. By providing the conveying device 6, it effectively transports the material that cannot pass through the sieve mesh 5 during the material screening process to the main body 1 for secondary crushing, playing a role in transporting the material that cannot pass through the sieve mesh 5, reducing the time-consuming and laborious process during the use of the device and the need for a large amount of manual labor, and improving the production efficiency of the device.

[0034] When the device is in use, when the second motor 75 operates, it drives the second rotating rod 76 to rotate. Subsequently, the rotation of the second rotating rod 76 drives the connecting ring 77 to rotate. When the connecting ring 77 rotates, it drives the connecting block 78 to rotate. Subsequently, the rotation of the connecting block 78 drives the rotating ring 711 to rotate. When the rotating ring 711 rotates, it drives the fixed rod 712 to rotate. Subsequently, the rotation of the fixed rod 712 drives the clamping block 713 to perform a circular motion. When the clamping block 713 performs a circular rotation, it drives the sliding plate 71 to move back and forth horizontally. By setting the protection device 7, it effectively deals with the situation where the materials that cannot pass through the sieve mesh 5 during the material screening process block on the surface of the sieve mesh 5 and cannot flow into the material distribution port 4, playing a role in preventing the materials from blocking on the surface of the sieve mesh 5 and not being able to flow into the material distribution port 4, reducing the problem that the non-passable materials block the material distribution port 4 when the device is in use, and improving the practicability of the device.
