Description

Technical Field

[0001] The utility model relates to the technical field of coal mine solidification backfilling, in particular to open-pit coal mine solidification backfilling equipment. Background Art

[0002] Coal mines, coal-rich mining areas, are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, it is generally chosen to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, it is generally chosen to directly strip the surface soil layer to mine coal. This is an open-pit coal mine. After the open-pit coal mine is not enough to continue mining, it needs to be solidified and backfilled.

[0003] In the existing coal mine backfilling, workers use carts to pull the waste rock from the open pit to another place for backfilling. The impact force generated by the rolling of the waste rock or the impact force generated by the collapse of a large area can easily cause damage to underground mining. Therefore, an open-pit coal mine solidification backfill equipment is proposed to solve the above problem. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides an open-pit coal mine solidification backfill equipment, which has the advantage of reducing impact force and solves the problem that in the existing coal mine backfilling, workers use carts to pull the waste rock from the open pit to another place for backfilling. The impact force generated by the rolling of the waste rock or the impact force generated by the collapse of a large area can easily cause damage to underground mining.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an open-pit coal mine solidification backfill equipment, comprising a connecting bin, wherein movable plates are placed on the inner top wall and the inner bottom wall of the connecting bin, and the right sides of the two movable plates are fixedly connected to limit plates.

[0006] The top and bottom surfaces of the connecting warehouse are both provided with sliding grooves, and the two movable plates are fixedly connected to a side surface close to the connecting warehouse with a slide having one end extending into the inside of the sliding groove, and the opposite sides of the two movable plates are fixedly connected to a first baffle, a second baffle and a third baffle from right to left, and a plurality of fixing nails are fixedly connected to the back side of the connecting warehouse.

[0007] The connecting compartment is provided with a driving assembly for driving the slide plate to move.

[0008] The connecting bin is provided with a moving component for driving the connecting bin to move.

[0009] Furthermore, the shape of the connecting warehouse is a rectangular parallelepiped with a hollow interior and missing left and right sides. The distance between the two second baffles is smaller than the distance between the two first baffles and larger than the distance between the two third baffles. The limiting plate is an inclined plate, and the slide plate and the slide groove are slidably connected.

[0010] Furthermore, the drive assembly includes four first electric push rods, which are fixedly mounted on the top and bottom surfaces of the connecting bin in groups of two. A linkage plate is fixedly connected between the output ends of two adjacent first electric push rods, and the linkage plate is fixedly connected to the slide. Four support grooves are provided inside the connecting bin, and the front and back surfaces of the two slides are fixedly connected to support blocks with one end extending into the inside of the support groove.

[0011] Furthermore, the four support blocks are slidably connected to the four support slots respectively, and two of the slide slots are located between the four first electric push rods.

[0012] Furthermore, the moving assembly includes four second electric push rods, and the four second electric push rods are fixedly connected to the top and bottom surfaces of the connecting warehouse in groups of two. The output ends of the four second electric push rods are fixedly connected to a mounting plate, the backs of the four mounting plates are fixedly connected to a mounting rod, the backs of the four mounting rods are fixedly connected to a fixing plate, and the backs of the four fixing plates are fixedly installed with moving wheels.

[0014] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0015] The open-pit coal mine solidification backfill equipment cushions the waste rock through the action of the first baffle, the second baffle and the third baffle, reduces the impact force and improves the safety of underground mining. The sliding connection between the slide plate and the slide chute drives the movable plate to move, and tries to avoid the waste rock from blocking the inside of the connecting bin. At the same time, the connecting bin is driven to move under the action of the moving wheel, which is more convenient and practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The four support blocks 8 are slidably connected to the four support grooves 12 respectively, and the two sliding grooves 11 are located between the four first electric push rods 4.

[0030] It should be noted that the first electric push rod 4 and the second electric push rod 13 are conventional devices known to the public in the prior art, and their specific structures and working principles are not described in detail herein.

[0031] Specifically, the connecting warehouse 1 is pushed, and the connecting warehouse 1 is driven to move under the action of the moving wheel 18. When the connecting warehouse 1 is in a suitable position, the second electric push rod 13 is started, and the output end of the second electric push rod 13 drives the moving wheel 18 to move through the cooperation between the mounting plate 15 and the mounting rod 16, so that the moving wheel 18 is separated from the ground, and the connecting warehouse 1 is fit to the ground. The mounting plate 15 is supported by the sliding connection between the positioning block 19 and the positioning groove 14, thereby improving the stability of the mounting plate 15.

[0032] The working principle of the above embodiment is:

[0033] Push the connecting bin 1, and drive the connecting bin 1 to move under the action of the moving wheel 18.
