Description

Technical Field

[0001] This utility model relates to the field of mining technology, and in particular to a stone sorting device for mining operations. Background Technology

[0002] Ore refers to rocks containing a valuable mineral that have been extracted from a mine. After the ore is extracted from the mine, it needs to be screened to separate stones of different particle sizes.

[0003] The existing stone sorting devices have the following problems compared with the existing technology: The existing stone sorting devices have relatively fixed screening structures, and most of them use vibrating flat screen plates to screen the stones. The agitation effect of the stones during the screening process is poor, resulting in low efficiency of stone sorting operation. Secondly, the existing stone sorting devices generate a lot of dust during the sorting operation, which will affect the air quality of the workshop and also cause harm to the health of the workers. To address these issues, we propose a stone sorting device for mining operations. Utility Model Content

[0005] The present invention solves its technical problem through the following technical solution: It includes a frame, with a sorting mechanism installed on the inner wall of the frame. The sorting mechanism includes a mounting bracket, which is fixed to the inner wall of the frame by bolts. Multiple screening discs are fixed inside the mounting bracket, with the screening size of the multiple screening discs decreasing sequentially from top to bottom. A protective cover is fixed to the top of each screening disc, and a top cover is fixed to the top of the protective cover. A feed pipe is fixed to the outer side of the top cover.

The stone is agitated by the feeding mechanism, and multiple screening discs 220 perform multi-stage sorting operations. The sorted stone is discharged through the discharge mechanism and the discharge hopper 260. During the sorting process, the stone is well agitated, improving its flowability within the screening disc 220 and thus increasing the efficiency of the sorting operation. The adsorption mechanism adsorbs the dust generated during the sorting operation, preventing direct emission of dust to the outside, ensuring air quality in the workshop, avoiding harm to workers, and improving the practicality of the device.

[0029] Specifically, the material feeding mechanism includes a motor mounting bracket 310, which is fixed to the top of the top cover 240 by bolts. A reduction motor 320 is fixed to the inner wall of the motor mounting bracket 310. A drive shaft 330 is provided at the output end of the reduction motor 320. Multiple feeding blades 340 are fixed to the outer side of the drive shaft 330. By providing the material feeding mechanism, during the sorting operation, the feeding blades 340 agitate the stones inside the screening disc 220, which can guide and move the stones, improve the flowability of the stones inside the screening disc 220, and thus improve the efficiency of the sorting operation.

[0030] Specifically, multiple protective bushings 331 are fixed on the outer side of the drive shaft 330 near the material feeding blade 340; by providing protective bushings 331 to protect the drive shaft 330, it is possible to prevent the stones from bumping into the drive shaft 330 during the sorting operation.

[0031] Specifically, the discharge mechanism includes a discharge trough 410, which is bolted to the outside of the screening disc 220. A mounting slide 420 is fixed to the outside of the discharge trough 410, a hydraulic rod 430 is fixed to the top of the mounting slide 420, a sealing baffle 440 is fixed to the bottom of the hydraulic rod 430, and a connecting rod 450 is fixed to the outside of the sealing baffle 440. The sealing baffle 440 is slidably connected to the discharge trough 410. By providing the discharge mechanism, when it is necessary to discharge the stone material screened inside the screening disc 220, the sealing baffle 440 of the hydraulic rod 430 moves upward, and the connecting rod 450 drives multiple sealing baffles 440 to move upward synchronously, opening the discharge trough 410. At this time, the stone material inside the screening disc 220 is discharged from the discharge trough 410 under the action of the feeding blade 340.

[0032] Specifically, the adsorption mechanism includes a mounting cylinder 510, which is bolted to the top of the frame 100. An adsorption tube 520 is fixed to the top of the mounting cylinder 510 and connected to the top cover 240. A mounting bracket 530 is bolted to the bottom of the adsorption tube 520. A suction fan 540 is fixed to the inner wall of the mounting bracket 530, and a suction pipe 541 is fixed to the top of the suction fan 540. The suction pipe 541 is connected to the mounting cylinder 510. A filter assembly 550 is slidably connected to the inner wall of the mounting cylinder 510. By providing the adsorption mechanism, during the sorting operation, the adsorption tube 520 adsorbs the dust generated during sorting, and the filter assembly 550 filters the dust, preventing dust from being released to the outside, ensuring the air quality of the workshop, and avoiding harm to the workers.

[0033] Specifically, a mounting panel 560 is fixed to the outside of the filter assembly 550, a handle 561 is fixed to one side of the mounting panel 560, and a plurality of fastening bolts 570 are provided on the outside of the mounting panel 560.

[0034] Working Principle: During operation, the main control unit 110 controls the operation of the stone material, which enters the top screening disc 220 through the feed pipe 250. During the sorting operation, the reduction motor 320 drives the drive shaft 330 to rotate, which in turn drives multiple feeding blades 340 to rotate. The feeding blades 340 agitate the stone material inside the screening disc 220, guiding and moving the stone. Multiple screening discs 220 perform multi-stage sorting of the stone material. When it is necessary to discharge the stone material screened out of the screening disc 220, the sealing barrier of the hydraulic rod 430 is activated. Plate 440 moves upward, and through linkage rod 450, multiple sealing baffles 440 move upward synchronously, opening the discharge trough 410. At this time, the stone inside the screening disc 220 is discharged from the discharge trough 410 under the action of the material pushing blades 340. Finally, the sorted stone is discharged through the discharge hopper 260. During the sorting operation, the suction fan 540 is started. The suction fan 540 performs a suction operation on the installation cylinder 510 through the suction pipe 541, so that the adsorption pipe 520 generates suction force. The dust generated during the sorting is adsorbed through the adsorption pipe 520 and filtered through the filter assembly 550.
