The crusher 2 comprises a crusher box 21, an upper feeding pipe 22, a lower feeding pipe 23 and an auxiliary feeding pipe 24; the upper feeding pipe 22 is communicated with the lower feeding pipe 23 through a zigzag loop 25; a glass window 221 is arranged on the pipeline of the upper feeding pipe 22, and a laser ranging sensor 222 is arranged in the upper feeding pipe 22. A press rod 211 and a press plate 212 are arranged in the crusher box body 21; platen 212 is a high strength steel of non-uniform thickness. An auxiliary feeding pipe 24 is arranged on the other side, opposite to the feeding pipe, of the side wall of the crusher box body 21, one end of the auxiliary feeding pipe 24 is close to the upper end of the crusher box body 21, and the other end of the auxiliary feeding pipe 24 is close to the bottom of the crusher box body 21; a one-way baffle 241 is arranged in the auxiliary feeding pipe 24; the crusher box 21 is connected to the crusher 3 by a crusher feed pipe 8. Bottom plate 26 of crusher box 21 is the inclined plane, is close to one side height of feed pipe 23 down, is close to one side low of rubbing crusher feed pipe 8. The inlet of the crusher feed pipe 8 is provided with a crusher outlet baffle 81. The crusher outlet baffle 81 is connected to a hydraulic ram 82 in a hydraulic control unit (not shown). The baffle 81 is controlled by a hydraulic device, and when the pressure plate 212 is pressed down, the hydraulic rod 82 blocks the baffle 81 at the discharge hole of the crusher; when the press plate 212 is raised and the crusher box 21 is discharged, the hydraulic rod 82 lifts the baffle 81 to allow the gangue fragments to enter the crusher 3.
The pulverizer 3 comprises a pulverizer box 31, wherein a first roller set 32, a second roller set 33, an inclined sliding plate 34, a vibrating screen 35 and a gangue powder outlet pipe 36 are arranged in the pulverizer box 31 from top to bottom; the shredder housing 31 is connected to the impeller 4 by an inlet pipe 41 and an outlet pipe 42.

When the laser ranging sensor 222 tests that the waste rock is full of the upper feeding pipe 22, the control baffle 12 is shifted to the other side, the crusher 2 starts to work, the pressing rod 211 drives the pressing plate 212 to press downwards, and the large waste rock is crushed by using pressure, so that the purpose of crushing the waste rock is achieved; meanwhile, when the pressing plate 212 descends, the gangue in the upper feeding pipe 22 enters the crusher box 21 and falls onto the pressing plate 212, and when the pressing plate 212 rises again, the gangue falling onto the pressing plate 212 enters the auxiliary feeding pipe 24.
The upper and lower ports of the auxiliary feeding pipe 24 are respectively connected with the upper and lower ends of the crusher box 21 and used for guiding the gangue falling on the pressing plate 212 from the upper feeding pipe 22 into the crusher box 21; a one-way baffle 241 is provided in the auxiliary feed tube 24 to prevent the gangue from being forced into the auxiliary feed tube 24 during the descent of the platen 212.
A baffle 81 is arranged at the discharge port of the crusher box body 21, the baffle 81 is controlled by a hydraulic device, and when the pressing plate 212 is pressed down, the hydraulic rod blocks the baffle 81 at the discharge port of the crusher 2; when the pressing plate rises and the crusher box 21 is used for discharging, the hydraulic rod lifts the baffle 81, so that the gangue fragments enter the crusher 3.
The roller spacing of the first roller set 32 is larger than that of the second roller set 33, and the inclined sliding plate 34 guides the gangue crushed from the roller space to the high side of the vibrating screen 35; the vibrating screen 35 is placed in an inclined position with the side adjacent the pulverizer feed tube 8 being higher and the side adjacent the impeller inlet tube 41 being lower.
Impellers in the impeller 4 are welded in the box body at equal intervals, the number of the impellers is 12-15, and included angles formed by the impellers and a circumferential tangent line are arranged in an anticlockwise manner; the gangue which does not pass through the vibrating screen 35 enters the impeller 4 and enters the crusher 3 again to be crushed under the driving of the impeller until the particle size of the product is reached.
The gangue powder outlet pipe 36 is shaped like a Chinese character 'zheng', which can effectively slow down the transportation speed of gangue powder, and can simultaneously cause dust to generate sedimentation, thus fundamentally eliminating dust pollution.
The invention realizes the continuous waste rock crushing: when the waste rock is almost full of the box body of the crushing machine, the laser sensor transmits a signal to the control baffle, so that the waste rock enters the other crushing machine, and the continuity of the crushing work is ensured. Completely crushing the gangue to reach the specified particle size: the waste rock is extruded by a crusher and then enters a crusher, and the waste rock reaching the specified particle size is conveyed away from a discharge port; and transporting the particles which do not meet the requirements by an impeller, and returning the particles to the pulverizer again for secondary pulverization until the particles reach the specified particle size. The sealing and crushing can not generate dust pollution: the whole device adopts sealed crushing and smashing to prevent and control dust pollution; meanwhile, the gangue powder outlet pipe is in a zigzag shape, so that dust is settled to eliminate dust pollution.
The above description is only an example of the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
