Impact crusher can process materials with a side length of less than 100 to 500 mm, with a maximum compressive strength of up to 350 MPa, a large crushing ratio, and the materials after crushing are cubic particles. It is widely used in building materials, ore crushing, railways, highways, energy, transportation, energy, cement, mining, chemical industry and other industries for fine crushing of materials. The hammer crusher in the impact crusher works on the principle of crushing and throwing out the materials through the high-speed swinging hammer head, and cooperating with the impact plate to impact and crush the thrown materials.

The cleaning member 556 is preferably provided to the cleaning member 556 for cleaning the hammer head 53. The cleaning member 556 is preferably provided to the cleaning member 556 for cleaning the hammer head 53. The cleaning member 556 is preferably provided to the cleaning member 556 for cleaning the hammer head 53. The cleaning member 556 is preferably provided to the cleaning member 556 for cleaning the hammer head 53. When the main shaft 51 drives the plate hammer 53 to rotate, the plate hammer 53 and the cleaning block 5563 are in contact and move at the same time. A cleaning plate 5564 is provided on the cleaning block 5563, and the material of the cleaning plate 5564 is the same as the rubber material. Therefore, when the plate hammer 53 and the cleaning block 5563 are in contact and rotate, the cleaning plate 5564 can clean and scrape the hammer head of the plate hammer 53, and clean and scrape off the material residue remaining on the hammer head of the plate hammer 53 when the plate hammer 53 impacts the material. At the same time, by setting the material of the cleaning plate 5564 to rubber material, it is prevented that the plate hammer 53 is in contact with the hammer head of the plate hammer 53 for a long time. When the plate hammer 53 is cleaned and scratched, the plate hammer 53 will be scratched, thus affecting the service life of the plate hammer 53. By opening a square groove 5562 on the arc plate 5561, the material residues scraped off by the cleaning plate 5564 can enter the contact groove 552 through the square groove 5562. At the same time, after the plate hammer 53 and the cleaning plate 5564 are cleaned and scratched, a cleaning roller 5566 is provided on the arc plate 5561, so that the cleaning roller 5566 can clean and wipe the hammer head of the plate hammer 53 after cleaning and scratching, thereby preventing a large amount of dust generated during the crushing of materials from adhering to the hammer head of the plate hammer 53. After the material is crushed, the electric hydraulic cylinder 83 is turned on, and the output end of the electric hydraulic cylinder 83 drives the screen plate 82 to move up and down in the slide 84 through the slider 85, so as to screen the crushed material. At the same time, when the screen plate 82 moves downward, it can contact with the connecting mechanism 86, thereby preventing the screen plate 82 from getting stuck in the mesh of the screen plate 82 when the screen plate 82 is screening the crushed material, thereby causing the screen plate 82 to be blocked; When the sieve plate 82 is driven to move downward by the output end of the electric hydraulic cylinder 83, the ejection assembly 864 on the top of the square frame 861 is squeezed, so that the ejection assembly 864 can eject the material stuck in the mesh of the sieve plate 82. At the same time, when the sieve plate 82 moves downward, if the squeezing force of the sieve plate 82 on the ejection assembly 864 is too large, the square frame 861 is stretched by the buffer of the second spring 863, and at the same time, it moves toward the connecting rod 862 through the square frame 861, so as to avoid the squeezing force between the sieve plate 82 and the ejection assembly 864 being too large, which will cause squeezing damage to the ejection assembly 864. When the sieve plate 82 moves downward, the ejection block 8644 moves toward the mesh of the sieve plate 82, so that the ejection block 8644 ejects the material stuck in the mesh of the sieve plate 82. At the same time, when the material is tightly stuck between the mesh of the sieve plate 82, the ejection block 8644 is squeezed by the extrusion force, driving the guide rod 8643 to move downward. The guide rod 8643 squeezes the connecting rods 8646 on both sides downward, and the connecting rod 8646 drives the arc block 8647 to slide in the moving groove 8650. At the same time, the sieve plate 82 continues to move downward, so that the ejection block 8644 continues to squeeze the material stuck in the mesh of the sieve plate 82. At the same time, when the sieve plate 82 continues to move downward, the scraper 8649 can clean the mesh of the sieve plate 82, thereby It is able to perform appropriate scraping according to the force with which the material is stuck in the mesh. When the material is stuck in the mesh more tightly, the squeezing force between the ejection block 8644 and the material is greater, so that the arc block 8647 drives the scraper 8649 to slide out of the movable groove 8650 over a larger area, so that when the ejection block 8644 ejects the material, the scraper 8649 can clean the inner wall of the mesh, thereby preventing the material from getting stuck in the mesh more tightly, the greater the friction between the mesh and the material, and more debris and dust remaining on the inner wall of the mesh. At the same time, a rubber block 8648 is provided on the side of the arc block 8647, so that when the scraper 8649 cleans and scrapes the mesh, the friction between the scraper 8649 and the inner wall of the mesh is increased, thereby preventing the scraper 8649 from slipping when scraping.
