[0003] Existing waste rock backfill processing equipment in mining areas mostly uses large-scale mechanical compaction, which cannot be carried out in narrow areas and corners, and cannot pump the cement slurry in the cement slurry barrel into the discharge pipe, making it inconvenient to grout the cracks. Utility Model Content

A small pressure pump is turned on to pump the cement slurry in the cement slurry barrel into the discharge pipe, which is convenient for grouting treatment at the cracks, thereby improving the overall bearing capacity and stability of the waste rock backfill in mining areas.

[0005] The technical solution adopted by the utility model to solve the technical problem is a mining waste rock backfill processing device, comprising a base, a cement slurry barrel and a small rammer, the top of the base is equipped with a cement slurry barrel by bolts, and a small pressure pump is installed on one side of the top of the cement slurry barrel through a mounting seat, one end of the cement slurry barrel is provided with a top plate through a column, and a sliding groove is welded on one side of the top plate, a sliding block slides in the sliding groove, sliding holes are opened on both sides of the sliding groove, and a sliding screw slides in the sliding hole, and one end of the sliding screw is connected to the sliding block;

The bottom corner of the mounting plate B is connected to a mounting plate A through a connecting spring, and a small rammer is installed on the bottom of the mounting plate A through bolts.

[0007] By adopting the above technical solution, turning on a small rammer makes it easier to compact the waste rock backfill area, improve the degree of compaction, and avoid the disadvantage of being unable to use a large roller for compaction in narrow areas and corners. Turning on a small pressure pump to pump the cement slurry in the cement slurry barrel into the discharge pipe makes it easier to grout the cracks, thereby improving the overall bearing capacity and stability of the waste rock backfill in the mining area.

[0008] Specifically, the suction end of the small pressure pump is located at the bottom of the cement slurry barrel, and the discharge end of the small pressure pump is connected to the discharge pipe.

[0009] By adopting the above technical solution, a small pressure pump is turned on to pump the cement slurry in the cement slurry barrel into the discharge pipe, so as to facilitate grouting treatment at the cracks.

[0010] Specifically, a top cover is clamped on the top of the cement slurry barrel, and a brakeable universal wheel is installed at the bottom corner of the base through bolts.

[0011] Specifically, a handle is welded on the top of the base and on one side of the cement slurry barrel.

[0013] Specifically, the other end of the sliding screw is sleeved with a locking nut and the locking nut is located outside the sliding hole.

[0014] By adopting the above technical solution, the locking nut is loosened to allow the sliding screw to slide in the sliding hole, thereby sliding the sliding block to the outermost end of the sliding groove.

[0015] Beneficial effects of the utility model:

[0016] (1) The utility model discloses a mining waste rock backfill processing device. Opening the top cover facilitates pouring the stirred cement slurry into the cement slurry barrel, which is convenient for centralized storage and use.

The handle facilitates pushing the entire device to the mining waste rock backfill area. The vertical electric cylinder drives the small rammer to move downward and contact the reference surface of the mining waste rock backfill area.

[0017] (2) The utility model discloses a device for processing waste rock backfill in a mining area. By turning on a small rammer, it is convenient to compact the waste rock backfill area and improve the degree of compaction, thereby avoiding the disadvantage that a large roller cannot be used for compaction in narrow areas and corners.
