[0002] In the mining industry, tailings backfilling technology is a key means to achieve green mining and efficient resource utilization. As the core equipment of the tailings backfilling system, the performance of the mixing box plays a decisive role in the backfilling quality.

[0003] The existing mixing tank has an unreasonable internal mixing structure design, which easily creates dead zones in the mixing process, making it difficult to achieve uniform mixing of materials such as tailings, cement, and water. This results in uneven strength of the filling body, posing safety hazards and failing to meet the usage requirements. Therefore, we propose a mixing tank for tailings filling systems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a mixing box for tailings backfilling systems, which has the advantage of good mixing effect. It solves the problems of unreasonable internal mixing structure design of existing mixing boxes, which easily creates mixing dead zones during operation, making it difficult to achieve uniform mixing of materials such as tailings, cement and water, resulting in uneven strength of the backfill body, safety hazards, and failure to meet the requirements of use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mixing box for a tailings backfilling system, comprising a support plate, a material box on one side of the support plate, a dual-shaft motor fixedly connected to the central shaft at the top of the material box, a drive shaft fixedly connected to the bottom output end of the dual-shaft motor, a stirring blade fixedly connected to the central shaft at the surface of the drive shaft, a drive gear fixedly connected to the bottom of the drive shaft, a driven gear meshing with the outer side of the drive gear, a connecting shaft fixedly connected to the top of the driven gear, a spiral blade fixedly connected to the surface of the connecting shaft, an arc-shaped plate provided on the outer side of the spiral blade, and one side of the arc-shaped plate fixedly connected to the material box.

[0006] Preferably, a rotating shaft is fixedly connected to both the front and back of the material box, a reciprocating screw is provided on the left side of the material box, a threaded sleeve is threadedly connected to the surface of the reciprocating screw, a fixing pin is fixedly connected to both the front and back of the threaded sleeve, a movable rod is movably connected to the surface of the fixing pin, a connecting seat is movably connected to one side of the movable rod, and the bottom of the connecting seat is fixedly connected to the support plate.

[0007] Preferably, a circular hole is provided at the bottom of the inner cavity of the material box, and a sealing ring is fixedly connected to the inner cavity of the circular hole.

[0008] Preferably, the bottom of the reciprocating screw is movably connected to a fixing plate via a first bearing, and one side of the fixing plate is fixedly connected to the material box.

[0009] Preferably, the inner cavity of the threaded sleeve is slidably connected to a slide rod, and the bottom of the slide rod is fixedly connected to the fixing plate.

[0010] Preferably, a vertical plate is movably connected to one side of the rotating shaft via a second bearing, and the bottom of the vertical plate is fixedly connected to a support plate.

[0012] Compared with the prior art, the present invention provides a mixing box for a tailings backfilling system, which has the following advantages:

[0013] 1. This utility model pours the material into the inner cavity of the material box, and then starts the dual-axis motor through the external PLC controller. The dual-axis motor drives the drive shaft to rotate, which in turn drives the stirring blade to rotate, thereby agitating the material. The drive shaft also drives the drive gear to rotate, which in turn drives the driven gear to rotate, which in turn drives the connecting shaft to rotate, which in turn drives the spiral blade to rotate, thereby causing the material at the four corners of the bottom of the inner cavity of the material box to rise and further tumble, avoiding the existence of dead corners for mixing.

[0014] 2. The operation of the dual-axis motor of this utility model will also cause the reciprocating lead screw to rotate, which in turn drives the threaded sleeve to move. The threaded sleeve drives the fixed pin to move, and the fixed pin drives the movable rod to rotate around the connecting seat. This causes the material box to oscillate back and forth around the rotating shaft, which further improves the mixing efficiency and facilitates the discharge of materials.
