[0028] Specifically, during the material screening process, the delivery pump 408 is started, and the delivery pump 408 delivers the water in the water tank 406 to the dust suppression water pipe 401 through the delivery hose 404, and sprays the water through the dust suppression nozzle 410 to perform dust reduction. At the same time, the electric push rod 403 is started, and the fixed ring 409 is driven to move by the electric push rod 403, and then the dust suppression water pipe 401 is driven to move by the fixed ring 409, so that the two dust suppression water pipes 401 drive the dust suppression nozzle 410 to move back and forth in the material screening area to perform dust reduction processing; In a specific application scenario, the unloading dust reduction module 4 is suitable for the sand and gravel unloading link, that is, the unloading dust reduction module 4 can spray water mist when in use, so as to carry out dust reduction treatment on the fine dust generated in the crushing link when the sand and gravel are unloaded, thereby avoiding the dispersion of fine dust during the crushing of sand and gravel, thereby increasing the cleanliness of the working environment of the device when in use, and at the same time, by carrying out dust reduction treatment on the fine dust, it can avoid the staff from inhaling it, thereby increasing the diversity of use of the device when in use, and further increasing the safety effect of the device.

[0029] In addition, the traditional crusher main shaft bearing is lubricated with grease. The temperature of the bearing is high when it rotates, and it may get stuck after working for a period of time. Moreover, the grease lubrication method cannot be used for higher speed requirements. Therefore, a new design is made: 1. A radial oil drain hole is arranged on the end cover, an oil inlet hole is arranged on the bearing cover, and a thin oil station is added. The thin oil station is connected with the oil inlet hole and the oil drain hole to realize the replacement of grease lubrication with thin oil circulation lubrication, which reduces the heating of the bearing and can be applied to higher speed occasions.

[0030] 2. Since the thin oil is a fluid, the sealing structure needs to be optimized. An oil-slinging plate is provided between the end cover and the bearing. The main shaft drives the oil-slinging plate to rotate, which has a certain blocking effect on the thin oil and prevents the thin oil from flowing into the gap between the oil-slinging plate and the end cover.

[0031] 3. A sealing ring is provided between the oil-slinging pan and the end cover to further prevent the thin oil from flowing out from the gap between the oil-slinging pan and the end cover.

[0032] A method for unloading a sand and gravel high-power impact crusher that is convenient for unloading, using the sand and gravel high-power impact crusher that is convenient for unloading as described above, comprises the following steps: Step 1. Before use, rotate the hole adjustment frame 602 to change the size of the sieve holes on the screening frame 615 for sand and gravel to pass through the hole adjustment frame 602 and the hole adjustment port 614. After the sand and gravel raw materials are crushed by the crusher body 2, start the electric telescopic rod 613 to drive the unloading frame 603 to enter the crusher body 2 through the electric telescopic rod 613, so that the sand and gravel enter the unloading frame 603. Then start the motor 1 611, and drive the driving gear 610 to rotate through the motor 1 611. Since the driving gear 610 is meshed with the driven gear 609, the motor 1 611 drives the driven gear 609 and the mounting rod 605 to rotate, thereby driving the mounting rod 605 and the winding wheel 612 to rotate, so that the winding wheel 612 relaxes the connecting cable 604, and then the telescopic spring 608 drives the closing baffle 607 to descend to close the sand and gravel entrance area of ​​the unloading frame 603. Then the electric telescopic rod 613 drives the unloading frame 603 to reset, and then As the unloading frame 603 moves, the sand and gravel are driven to move to the rectangular opening 8, so that they fall into the inside of the feeding frame 601, and then enter the inside of the fixed frame 628 through the feeding opening 630. At this time, the motor three 627 is started, and the motor three 627 drives the toothless gear 626 to rotate, thereby driving the connecting tooth plate 618 to move, and then driving the connecting arc rod 616 and the fixed rod 619 to move, so that the two feeding push plates 633 move to the opposite side to push the sand and gravel into the screening frame 615. Then the toothless gear 626 and the connecting tooth plate 618 are temporarily separated, and the feeding push plate 633 is driven to reset by the reset spring 629 to repeat the operation, and with the operation, the stirring member 625 can drive the sand and gravel inside the screening frame 615 to move, and at the same time, the motor two 622 is started, and the motor two 622 can drive the transmission gear 623 to rotate, thereby driving the gear ring 624 and the screening frame 615 to rotate, so as to screen the unloaded sand and gravel until the unloading is completed; Step 2: During the material unloading and screening process, the delivery pump 408 is started, and the delivery pump 408 delivers the water in the water tank 406 to the dust suppression water pipe 401 through the delivery hose 404, and sprays the water through the dust suppression nozzle 410 to perform dust reduction. At the same time, the electric push rod 403 is started, and the fixed ring 409 is driven to move by the electric push rod 403, and then the dust suppression water pipe 401 is driven to move by the fixed ring 409, so that the two dust suppression water pipes 401 drive the dust suppression nozzle 410 to move back and forth in the material unloading and screening area to perform dust reduction processing until the unloading is completed; Step three, after the unloading is completed, the driving motor 302 is started, and the partition member 303 is driven to rotate by the driving motor 302, so that the partition member 303 rotates to the inside of the unloading bin 5, and the adjusting hole frame 602 is rotated at the same time to make the sand and gravel that do not meet the crushing standard fall down, and then the sand and gravel that do not meet the crushing standard slide through the partition member 303 to the mounting support frame 301, and then enter the transmission sleeve 306 area, at this time, the universal motor 312 is started, and the universal motor 312 can drive the transmission screw rod 309 to transmit the sand and gravel that do not meet the crushing standard, and transport it to the fixed plate frame 310, and with the continuous transmission, the sand and gravel will fall on the conveyor belt 305, at this time, the stepper motor 311 is started, and the stepper motor 311 can drive the conveying roller 308 to rotate, and then the conveying roller 308 drives the conveyor belt 305 to transport the sand and gravel that do not meet the crushing standard, so that it enters the crusher body 2 for re-crushing.
