[0023] The box door 21 is hinged to the inner side of the cover body 1. When the dustproof protective cover is in use, the lower end of the hopper 3 is fixedly connected to the disc crusher. When the large tree trunks to be crushed are transported to the top of the cover body 1 by the conveyor, the weight of the large tree trunks will push the box door 21 to open inward. The inner side of the box door 21 is fixedly connected with a torsion spring 22, and the other end of the torsion spring 22 is fixedly connected to the inner wall of the cover body 1. A groove 23 is opened on the inner side of the cover body 1. A positioning rod 24 is fixedly connected to the inner side of the groove 23. The positioning rod 24 passes through and is slidably connected with a sliding bar 25. The inner side of the sliding bar 25 is fixedly connected with a screen 26. When the box door 21 rotates inward, due to the certain inclination directly in front of the cover body 1, the box door 21 rotates inward, which will push the sliding bar 25 to retract inward, and the sliding bar 25 will compress the telescopic spring 27 when being pushed, and the tightened spiral spring 29 will also drive the rotating rod 28 to rotate. , so that the rotating rod 28 reels in the screen 26, and allows the large tree trunks to fall into the crusher through the hopper 3 for crushing. The two ends of the sliding bar 25 close to the screen 26 are fixedly connected with telescopic springs 27, and the end of the telescopic spring 27 away from the sliding bar 25 is fixedly connected to the inner side of the groove 23. When the tree trunk completely passes through the hopper 3, the torsion spring 22 will pop up and reset the box door 21. At the same time, the compressed telescopic spring 27 will push the sliding bar 25 to reset, so that the screen 26 is pulled away from the rotating rod 28 to prevent excessive wood chips or dust from endangering the health of the staff or causing safety hazards when crushing large tree trunks. The rotating rod 28 is rotatably connected to the inner wall of the cover body 1, and the end of the screen 26 away from the sliding bar 25 is fixedly connected to the surface of the rotating rod 28. The two end surfaces of the rotating rod 28 are fixedly connected with volute springs 29, and the other end of the volute spring 29 is fixedly connected to the inner wall of the cover body 1. The rotating rod 28 penetrates and is fixedly connected with the roller 1 210, the surface of the roller 1 210 is connected with a belt 211, the end of the belt 211 away from the roller 1 210 is connected with the roller 2 212, the roller 2 212 is penetrated and fixedly connected by the threaded rod 213, the threaded rod 213 penetrates the cover body 1 and is connected in rotation. The threaded rod 213 penetrates and is threadedly connected with the screw sleeve 214, and when the rotating rod 28 reciprocates, it will drive the roller 1 210 to reciprocate back and forth, and further drive the threaded rod 213 to reciprocate back and forth through the belt 211 and the roller 2 212, the left side of the screw sleeve 214 is fixedly connected with a slide bar 216, and the end of the slide bar 216 away from the screw sleeve 214 is fixedly connected with a scraper 217. A connecting column 215 is fixedly connected to the inner wall of the cover body 1. While feeding repeatedly, the box door 21 will be repeatedly opened and closed, so that the rotating rod 28 will be repeatedly pulled back and forth by the spiral spring 29. At the same time, when the screen 26 is reciprocated and stretched and passes through the connecting column 215, the edge of the connecting column 215 will scrape the wood chips and dust on the surface of the screen 26 and enter the interior of the connecting column 215. A slide groove 218 is provided on the inner side of the connecting column 215, and an ash discharge port 219 is provided on the right side surface of the cover body 1.There are two groups of door 21, and the two groups of door 21 are symmetrically arranged with the center line of the cover body 1 as the axis of symmetry. The slide bar 216 penetrates the slide slot 218 and is slidably connected. Since the slide bar 216 penetrates the slide slot 218, the slide slot 218 vertically limits the slide bar 216, so that the slide bar 216 can only slide along the slide slot 218, so that the screw sleeve 214 drives the slide bar 216 to slide back and forth, and the slide bar 216 drives the scraper 217 to slide back and forth inside the connecting column 215, and scrapes the wood chips and dust that fall into the connecting column 215 to the ash discharge port 219 for discharge, which is convenient and quick, and can automatically clean while protecting.
[0024] Based on the above-mentioned fact, when the dustproof protective cover is used, the lower end of the hopper 3 is fixedly connected to the disc crusher. When the large tree trunks to be crushed are conveyed to the top of the cover body 1 by the conveyor, the weight of the large tree trunks will push the box door 21 to open inward. When the box door 21 rotates inward, since the front of the cover body 1 has a certain inclination, the box door 21 will push the sliding bar 25 to retract inward when it rotates inward, and the sliding bar 25 will compress the telescopic spring 27 when it is pushed, and the tightened scroll 27 will be tightened at the same time. The spring 29 will also drive the rotating rod 28 to rotate, so that the rotating rod 28 can reel in the screen 26, and allow large tree trunks to pass through the hopper 3 and fall into the crusher for crushing. When the tree trunks completely pass through the hopper 3, the torsion spring 22 will bounce the box door 21 back to its original position, and at the same time, the compressed telescopic spring 27 will push the sliding bar 25 to return to its original position, so that the screen 26 is pulled away from the rotating rod 28, preventing excessive wood chips or dust from endangering the health of workers or causing safety hazards when crushing large tree trunks.
[0025] At the same time, while repeatedly feeding, the box door 21 will be repeatedly opened and closed, so that the rotating rod 28 will be repeatedly pulled back and forth by the volute spring 29. At the same time, when the screen 26 is reciprocated and stretched and passes through the connecting column 215, the edge of the connecting column 215 will scrape the wood chips and dust on the surface of the screen 26 and enter the interior of the connecting column 215. When the rotating rod 28 reciprocates, it will drive the roller 1 210 to reciprocate back and forth, and further drive the threaded rod 210 through the belt 211 and the roller 212. 213 reciprocates back and forth, and since the slide rod 216 passes through the slide groove 218, the slide groove 218 limits the slide rod 216 vertically, so that the slide rod 216 can only slide along the slide groove 218, so that the screw sleeve 214 drives the slide rod 216 to slide back and forth, and the slide rod 216 will drive the scraper 217 to slide back and forth inside the connecting column 215, and scrape the wood chips and dust that fall into the connecting column 215 to the ash discharge port 219 for discharge, which is convenient and fast, and can automatically clean while protecting.
[0026] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
