[0016] (1) The utility model sets a screening mechanism. When in use, the material to be crushed is placed in the crusher casing. After the motor is started, the motor drives the rotating shaft, the weight and the pulley to rotate synchronously. When the weight rotates, the material is efficiently crushed by its high-intensity impact force. The crushed material can be screened by the up and down movement of the filter plate. Coarser materials cannot pass through the filter plate and roll out of the collection port through the slope vibration of the filter plate and are collected in the coarse particle collection box. Finer materials can pass through the plate holes of the filter plate and fall into the fine particle collection box for collection. The coarse and fine materials are screened by the vibration of the filter plate, which is beneficial to improving production efficiency, improving product quality and reducing energy consumption.

[0017] (2) The utility model provides an impact mechanism. When the heavy hammer crushes the material, the material will be subjected to the high-speed impact force of the heavy hammer, thereby spreading to the surroundings. At the same time, part of the material will collide with the impact baffle. When the impact baffle is hit, it will transfer the impact force to the rotating rod three connected to the rear thereof. The rotating rod three will drive the connected spring to be compressed. This process can absorb and alleviate the impact force on the impact baffle, thereby reducing the damage to the baffle and other components, and helping to protect the structural integrity of the crusher.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] A specific application of this embodiment is: when in use, the material to be crushed is placed in the crusher housing 2, and after the motor 6 is started, the motor 6 will drive the rotating shaft 1 7, the heavy hammer 8 and the pulley 11 to rotate synchronously. When the heavy hammer 8 rotates, the material will be efficiently crushed through its high-intensity impact force.

The round rod 14 produces an eccentric shaft effect. This eccentric shaft effect causes the connecting rod 23 to drive the sliding round rod 3 21 through the sleeve 22. The round rod 3 21 cooperates with the sleeve 1 20 rotating on the outer wall of the round rod 2 19, so that the filter plate 17 can move synchronously with the connecting rod 23 moving up and down. In this process, the round rod 3 21 on the filter plate 17 will change its length by changing its angle in the sleeve 22. By changing the length of the round rod 3 21 in the sleeve 22, the filter plate 17 can move synchronously with the connecting rod 23 moving up and down. In the process of up and down movement, it can better adapt to the change of angle, due to the up and down movement of the filter plate 17, the crushed material can be screened, the coarser material cannot pass through the filter plate 17, and will roll out of the collection port 24 through the slope vibration of the filter plate 17 and be collected in the coarse particle collection box 25, the finer material can pass through the plate eye of the filter plate 17, and will fall into the fine particle collection box 27 for collection, and the coarse and fine materials are screened by the vibration of the filter plate 17, which is beneficial to improve production efficiency, improve product quality, and reduce energy consumption. When the heavy hammer 8 crushes the material, the material will be subjected to the high-speed impact force of the heavy hammer 8, thereby spreading to the surroundings. At the same time, part of the material will also collide with the impact baffle 32. When the impact baffle 32 is hit, it will transmit the impact force to the rotating rod three 34 connected behind it, and the rotating rod three 34 will drive the connected round rod four 36 to be compressed. This process can absorb and alleviate the impact force received by the impact baffle, thereby reducing the damage of the baffle and other components, and helping to protect the structural integrity of the crusher.
