Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, and in particular to a novel potash ore conveying equipment. Background Technology

[0002] Potash is the core raw material for potash fertilizer production and has irreplaceable strategic significance for ensuring national food security and sustainable agricultural development. Global potash mining primarily employs underground hydraulic or dry mining methods. The extracted potash ore needs to be continuously, reliably, and efficiently transported from underground working faces hundreds or even thousands of meters underground to surface processing workshops. This transportation process is a crucial link between mining and refining, and its technological level directly affects the overall production efficiency, operating costs, and safety of the mine.

[0003] Currently, the mainstream method for transporting potash ore underground in China and abroad is to use belt conveyors. However, when potash ore has a high moisture content, it tends to adhere to the conveyor belt and idlers, which not only reduces the conveying efficiency and requires frequent shutdowns for cleaning, but also causes the hardened residue to aggravate equipment wear, disrupt the balance of the conveyor belt, and increase drive energy consumption.

Compared with existing technologies, this new potash ore conveying equipment features a unique fastener design that allows the guide plate to be quickly snapped in and out, facilitating replacement or thorough cleaning. The scraper component achieves rapid connection and separation from the drive mechanism through the cooperation of locking blocks, limiting blocks, and bolts. The scraper can be easily replaced after wear, making maintenance simple and quick, minimizing equipment downtime for maintenance. Attached Figure Description

[0030] Working principle: The conveyor motor is started, driving one of the conveyor rollers 26 to rotate. Under the action of friction, the conveyor belt 4 begins to circulate. The tension roller is used to maintain appropriate tension on the conveyor belt 4 to prevent slippage. Wet potash ore is continuously placed onto the running conveyor belt 4 and moves towards the outlet. After reaching the outlet, the ore is guided by the guide plate 3. Simultaneously, the top of the guide plate 3 scrapes the wet material adhering to the outer surface of the conveyor belt 4 onto the guide plate 3, smoothly unloading it to the next process. Simultaneously, the drive motor... 24 Start, drive the rotating shaft and the disc 18 at its end to rotate. The eccentric slide bar on the disc 18 then makes a circular motion. The slide bar passes through the waist hole 20 on the guide block 19, converting the circular motion into the reciprocating linear motion of the guide block 19 and the push rod 8 connected to it in the horizontal direction. The push rod 8 pushes the locking block 9, which in turn drives the vertical rod 7 and the scraper 6 fixed to it to slide back and forth along the top surface of the guide plate 3. During the reciprocating motion of the scraper 6, its cutting edge is in close contact with the outer surface of the guide plate 3. The scraper 6 scrapes off the material adhering to the outer surface of the guide plate 3.

[0031] When it is necessary to disassemble and replace the guide plate 3 and scraper 6, first remove the bolt 14, then separate the scraper 6 from the push rod 8, so that the scraper 6 is separated from the guide plate 3. Next, pull the pull block 15. The pull block 15 drives the positioning block 33 to leave the positioning groove 32 through the connecting rod 30 and retract into the second countersunk hole 29. At the same time, the spring 31 is compressed. Then, disassemble the guide plate 3 from the base 1, so that the support shaft 28 leaves the blind hole 27 in the fixing block 5. Then, install the new guide plate 3 to the base 1 through the support shaft 28 and the blind hole 27. Then, release the pull block 15, and the compressed spring 31 returns to its original position. The positioning block 33 enters the positioning groove 32 from the second countersunk hole 29. Then, connect the new scraper 6 to the vertical rod 7 through the slot 12 and the locking block 9, so that the scraper 6 fits against the outer surface of the guide plate 3, and then fix it with the bolt 14.
