The mixing device usually manually controls the slurry to be introduced into the backfilling pump set. The main problem is that the amount of slurry in the feed hopper of the backfilling pump set is difficult to control and cannot be controlled by sensors or buoyancy valves. This is mainly due to the difficulty in controlling the consistency of the tailings. Utility Model Content

Detailed Implementation
[0018] The embodiments of this utility model are further described below with reference to the accompanying drawings.
[0019] Example 1
[0020] like Figures 1 to 3As shown; a high-efficiency, high-concentration tailings filling device includes a filling pump set 1 and a feeding device 2. The feeding device 2 is connected to the inlet of the filling pump set 1. The feeding device 2 includes a hopper 21, a stirring device 22, a detection device 23, and a feeding port 24. The stirring device 22 and the detection device 23 are installed inside the hopper 21. The feeding port 24 is connected to one side of the hopper 21. The stirring device 22 and the detection device 23 are connected by a transmission. The detection device 23 includes a pulley 25, a rotating shaft 26, a rotating sleeve 27, a fixing frame 28, and a large inspection plate 29. The system includes a rotation detection device and a misalignment detection device. One end of the rotating shaft 26 is connected to the pulley 25, and the other end passes through the rotating sleeve 27. The large inspection plate 29 is connected to the rotating sleeve 27 via a fixing bracket 28. The rotation detection device and the misalignment detection device are connected to the left and right ends of the rotating sleeve 27 and cooperate with the rotating shaft 26. The rotation detection device includes a torsion spring 211 and a positioning tube 214. One end of the positioning tube 214 is threaded to the rotating shaft 26, and the other end is connected to the rotating sleeve 27 via the torsion spring 211. The misalignment detection device includes an adjusting rod 212 and an inspection rod 213. The system includes a positioning sleeve 215, an inclined plate 216, an inclined block 217, an angle positioning rod 218, a bullseye 219, a limiting rod 220, and a limiting sensor 221. The positioning sleeve 215 is connected to the rotating shaft 26 and one end is connected to the inclined plate 216. The inclined block 217 is connected to the rotating sleeve 27 and cooperates with the inclined plate 216. The angle positioning rod 218 is connected to the inclined plate 216. Two limiting rods 220 are symmetrically connected to the inclined block 217 and cooperate with the angle positioning rod 218. The bullseye 219 is connected to the side of the inclined block 217 closest to the inclined plate 216. The rotating shaft 26 has an oblong hole. One end of the inspection rod 213 extends through the rotating shaft 26 to one side of the oblong hole, and the other end cooperates with the limit sensor 221. One end of the adjusting rod 212 cooperates with the rotating sleeve 27, and the other end passes through the oblong hole and connects to the inspection rod 213. A small inspection plate 210 is connected to the fixing frame 28. Several screw holes for connecting the limit rod 220 are opened on the inclined block 217. Bullseye balls 219 are connected to the sides of the inclined plate 216 and the inclined block 217 that are close to each other. Several bolts for connecting the torsion spring 211 are connected to the rotating sleeve 27.
[0021] The stirring device 22 is connected to the pulley 25 via a transmission belt, so that the power of the stirring device drives the pulley 25 to rotate via the transmission belt, which in turn drives the rotating shaft 26 to rotate. The rotating shaft 26 drives the positioning sleeve 215, which in turn drives the angle positioning rod 218. The angle positioning rod 218 drives a limiting rod 220, which causes the inclined block 217 and the rotating sleeve 27 to rotate. The rotating sleeve 27 drives the fixed frame 28 and the large inspection plate 29 to rotate around the rotating shaft 26. When the large inspection plate 29 comes into contact with the slurry, the stirring force of the large inspection plate 29 increases, causing the inclined surfaces of the inclined plate 216 and the inclined block 217 to begin to misalign. The rotating sleeve 27 is moved away from the inclined plate 216. At the same time, the other limiting rod 220 rotates and collides with the angle positioning rod 218 to complete the positioning, preventing the rotating sleeve 27 from continuing to rotate due to resistance. At this time, the rotating sleeve 27 pushes the adjusting rod 212 to move, and the adjusting rod 212 drives the inspection rod 213 to move, so that the inspection rod 213 is disengaged from the limiting sensor 221 to achieve the purpose of detecting the height of the slurry liquid level. When the liquid level drops and the large inspection plate 29 is subjected to reduced resistance, the rotating sleeve 27 is rotated and reset by the torsion spring 211. The position of the torsion spring 211 is fixed by bolts, and the torque of the torsion spring 211 is adjusted to adapt to different slurries.
