Bucket elevator uses a series of buckets fixed on a traction chain or belt to transport bulk materials upward in a vertical or nearly vertical direction. There are three types: ring chain, plate chain and belt. Bucket elevator generally transports mineral materials from the ground to a high place. During the transportation process, all the materials will enter the elevator, but the speed and amount of material entering cannot be greatly controlled, which can easily clog the elevator, causing the transport bucket to be stuck, affecting the operation of the drive motor, and in serious cases, the starting motor may explode.

This mining explosion-proof bucket elevator exposes the feed holes on the driving wheel and the driven wheel by rotating the adjustment handle, and the degree of exposure can be adjusted. Finally, a clamp is used to limit the limit rod, and the clamp is fixed with a fixing nut, so that the speed and amount of ore introduction can be controlled, avoiding hoist blockage that affects the drive motor, reducing the loss of the drive motor, and preventing the drive motor from exploding.

[0004] However, the above-mentioned bucket elevator has poor precision in controlling the introduction speed and quantity, which still causes a long-term burden on the driving motor of the bucket elevator.

[0005] To this end, a mining bucket elevator is proposed, which has the advantages of adjustable introduction speed and quantity, thereby solving the problems in the above-mentioned background technology. Utility Model Content

[0023] In one embodiment, a pointer 8 is welded on the right connecting member 7, and a scale line 9 is engraved on the left side wall of the frame 1 corresponding to the pointer 8, and the value of the scale line 9 increases from bottom to top. By setting the pointer 8 and the scale line 9, the height of the import quantity adjustment plate 10 can be observed, so as to facilitate the purpose of knowing the blocking range of the feed port 15.

[0024] In one embodiment, through holes are provided at the facing ends of the left connecting member 11 and the right connecting member 7 corresponding to the threaded columns 13, and the left connecting member 11 and the right connecting member 7 are both arranged in a Z-shaped structure. The arrangement of the left connecting member 11 and the right connecting member 7 facilitates the installation and connection of the electric cylinder 6 and the telescopic rod 12.

[0025] In one embodiment, the introduction speed adjustment cylinder 5 is a cylindrical structure as a whole, and both ends of the introduction speed adjustment cylinder 5 are provided with open openings that are adapted to the internal dimensions of the feed hopper 2.

When the ore enters the feed hopper 2, the ore entering the feed hopper 2 from the left opening 18 is brought to the right opening 19 under the action of the diverter plates 17, thereby weakening the initial speed of the ore entering the feed hopper 2, making the rolling of the ore smoother. By starting the electric cylinder 6 to extend, the electric cylinder 6 is prompted to drive the introduction quantity adjustment plate 10 to move upward under the action of the right connecting piece 7. In this process, the telescopic rod 12 connected by the left connecting piece 11 follows the electric cylinder 6 to adaptively extend and retract, maintaining the stability of the movement of the introduction quantity adjustment plate 10, so that the introduction quantity adjustment plate 10 gradually leaves the state of blocking the feed port 15, and adjusts the actual opening size of the feed port 15 to achieve the purpose of adjusting the ore introduction quantity, until the ore passes through the feed port 15 and is transferred to the lifting hopper of the frame 1.
