At the same time, when the screen plate moves downward, it can be squeezed and contacted with the ejection mechanism, so that the ejection mechanism can eject the crushed stone stuck in the mesh of the filter plate, thereby avoiding interference with the normal screening work of the screen plate.

[0017] 4. The present invention is provided with an ejection mechanism. When the screen plate is driven to move downward by the output end of the servo motor, the screen plate and the ejector are squeezed at the same time, so that the ejector can eject the crushed stones stuck in the mesh of the screen plate. When the extrusion force between the crushed stones stuck in the mesh and the ejector is greater than the tensile force of the third spring, the ejector can drive the slider to slide in the notch through the extrusion shaft. At the same time, the buffering work of the third spring can prevent the extrusion force between the ejector and the crushed stones stuck between the mesh from being too large, thereby causing extrusion damage to the side of the ejector. At the same time, when When the ejector pin squeezes the gravel in the mesh plate, the scraping plate can clean and scrape the inner side of the mesh plate mesh, thereby avoiding a large amount of ore dust from accumulating on the inner wall of the mesh when the crushed ore is screened. At the same time, when the extrusion pressure between the scraping plate and the inner wall of the mesh is too large, the slider can be used to buffer and move in the groove at the same time, thereby avoiding excessive extrusion pressure between the scraping plate and the inner wall of the mesh, which will cause damage to the inner wall of the mesh. When the scraping cleaning is performed for a long time, the inner wall of the mesh will be worn, thereby causing the mesh to expand. BRIEF DESCRIPTION OF THE DRAWINGS

The ore in the feed shell 31 continuously enters the tank body 1 through the feed port 34, and at the same time, the output end of the double-axis motor 33 drives the first crushing roller 4 to rotate in the tank body 1, so that the first crushing roller 4 and the second crushing roller 5 crush the ore entering the tank body 1, and at the same time, the rotating mechanism 36 rotates in the inner cavity of the feed shell 31 and is squeezed and contacted with the spray mechanism 35, so that the spray mechanism 35 sprays and reduces dust around the feed shell 31;

[0047] The rotating mechanism 36 is driven to rotate in the inner cavity of the feed housing 31 through the output end of the dual-axis motor 33, and the side of the rotating mechanism 36 is squeezed and contacted with the squeezing block 353, so that the squeezing block 353 drives the squeezing plate 354 to move in the water storage tank 351 through the squeezing rod 352, so that the squeezing plate 354 squeezes the water flow in the water storage tank 351, so that the water flow in the water storage tank 351 flows through the water pipe 356, so that the ore in the feed housing 31 is sprayed and dusted through the spray head 357, so as to avoid a large amount of ore dust generated by the feed housing 31 when the ore is crushed and falls around the equipment;

[0048] When the rotating shaft 361 is driven by the output end of the dual-axis motor 33 to rotate in the inner cavity of the feed shell 31, the rotating shaft 361 jointly drives the rotating frame 362 to rotate in the inner cavity of the feed shell 31. At the same time, by providing a crushing block 364 on the side of the rotating frame 362, when the rotating shaft 361 drives the rotating frame 362 to drive and disperse the ore in the feed shell 31, part of the ore can be impacted by the crushing block 364, so as to avoid the ore from aggregating in the feed shell 31. At the same time, when the ore in the feed shell 31 continues to be fed, when the ore in the feed shell 31 becomes less and less, the squeezing force of the ore in the feed shell 31 on the contact assembly 365 is less than the centrifugal force when the rotating shaft 361 drives the rotating frame 362 to rotate, the contact mechanism is separated from the inner side of the rotating frame 362 by the action of the centrifugal force, and the inner side of the feed shell 31 is cleaned.

[0049] When the ore in the feed shell 31 continues to enter the tank body 1, the centrifugal force of the rotating frame 362 during the rotation of the rotating shaft 361 causes the connecting plate 3562 to detach from the inner side of the connecting frame 74 through the connecting shaft 363, so that the scraper 3563 cleans and scrapes the broken small ore adhering to the inner wall of the feed shell 31. At the same time, since the setting angle of the rubber plate 3564 is greater than the scraper 3563, the rubber plate 3564 contacts and cleans the inner wall of the feed shell 31, so that the rubber plate 3564 can clean and scrape off the dust and impurities adhering to the inner wall of the feed shell 31. At the same time, by setting the rubber plate 3564, it is avoided that the inner wall of the feed shell 31 is cleaned for a long time, which may cause scratches and damage to the inner wall of the feed shell 31.

[0050] When the ore crushed by the first crushing roller 4 and the second crushing roller 5 falls on the screen plate 72 through the filter plate 6, the servo motor 71 is turned on, and the screen plate 72 is driven to move up and down in the tank 1 through the output end of the servo motor 71, so as to screen the crushed ore. At the same time, when the screen plate 72 moves downward, it can be squeezed and contacted with the ejection mechanism 75, so that the ejection mechanism 75 can eject the crushed stones stuck in the mesh of the filter plate 6, thereby avoiding interference with the normal screening work of the screen plate 72;

[0051] When the screen plate 72 is driven by the output end of the servo motor 71 to move downward, the screen plate 72 and the ejector pin 754 are squeezed at the same time, so that the ejector pin 754 can eject the gravel stuck in the mesh of the screen plate 72. When the squeezing force between the gravel stuck in the mesh and the ejector pin 754 is greater than the tensile force of the third spring 757, the ejector pin 754 can drive the slider 758 to slide in the slot 752 through the squeezing shaft 753. At the same time, the buffering work of the third spring 757 can prevent the squeezing force between the ejector pin 754 and the gravel stuck in the mesh from being too large, thereby causing squeezing damage to the side of the ejector pin 754. At the same time, when the ejector pin 754 is squeezing the gravel in the mesh plate, the scraping plate 756 can clean and scrape the inner side of the mesh of the screen plate 72, thereby avoiding a large amount of ore dust from accumulating on the inner wall of the mesh when the crushed ore is screened. At the same time, when the squeezing pressure between the scraping plate 756 and the inner wall of the mesh is too large, the slider 758 can be used to buffer and move in the slot 752 at the same time, thereby avoiding excessive squeezing pressure between the scraping plate 756 and the inner wall of the mesh, which will cause damage to the inner wall of the mesh. When the scraping and cleaning is performed for a long time, the inner wall of the mesh will be worn, thereby causing the mesh to expand.
