[0002] Gold ore refers to gold-bearing ore extracted from mines manually or mechanically. After mining is completed, the mine shafts need to be backfilled to maintain the surrounding ecological environment. A common backfilling method is grouting with cement mixed with aggregates such as blast furnace slag and fly ash. The cement and aggregates are mixed at a mixing plant, and then transported into the mine shaft through grouting pumps and pipes to gradually complete the grouting and backfilling work.

[0003] In existing grouting and backfilling mixing plants, the mixed material in the mixing tank usually needs to be pumped out by grouting pumps and grouting pipes before the next batch of backfill material can be mixed. This grouting interval affects the backfilling efficiency of the grouting material to some extent.

Once the first mixing tank has finished discharging material, the second mixing tank is just finished mixing. Then, a dual-station cyclic switching component enables the second mixing tank to discharge mixed material into the backfill temporary storage tank. This cycle repeats continuously, achieving continuous material transport and improving backfilling efficiency. Utility Model Content

The cylinder body of the third telescopic cylinder is connected to the side of the first feed inlet 83, and the lower end of the third telescopic cylinder is connected to the side of the first frustum-shaped guide sleeve 85. A first sealing plate 88 for sealing the first feed inlet 83 is vertically mounted on the upper right side of the first frustum-shaped guide sleeve 85. When the third telescopic cylinder is in the extended state, at this time... Figure 4 As shown, the first sealing plate 88 does not block the first feed port 83, and at this time, the first frustum-shaped guide sleeve 85 is fastened to the first frustum-shaped guide head 43; when the third telescopic cylinder is in the retracted state, the first sealing plate 88 blocks the second feed port 84. This arrangement can reduce dust flying when the inverted U-shaped shell 81 conveys materials into the first box 41, thus reducing dust pollution.

[0032] A second frustum-shaped guide head is coaxially mounted on the upper end of the second feed inlet.

When the fourth telescopic cylinder 811 is in the telescopic state, at this time... Figure 5 As shown, the second sealing plate 812 blocks the second feeding port 84; when the fourth telescopic cylinder 811 is in the extended state, the second sealing plate 812 does not block the second feeding port 84.

[0033] The working principle is as follows: In the initial state, the movable plate 3 is located at the leftmost end of the rectangular opening. At this time, the first telescopic cylinder 94 is in the retracted state, the second telescopic cylinder 95 is in the extended state, and the fourth telescopic cylinder 811 is in the retracted state, causing the second sealing plate 812 to be located at the right end of the horizontal section of the inverted U-shaped shell 81, blocking the second feeding port 84. At this time, the extension of the third telescopic cylinder causes the first frustum-shaped guide sleeve 85 to move down and overlap the first frustum-shaped guide head 43. The material at the main feed hopper 813 is conveyed to the inside of the first mixing box 4 by the leftward conveying of the bidirectional belt conveyor 82. Then, the first mixing box 4 starts mixing. After mixing is completed, the third telescopic cylinder retracts, causing the first sealing plate 88 to move up to the left end of the horizontal section of the inverted U-shaped shell 81, blocking the first feeding port 83. Through the extension of the first telescopic cylinder 94 and the retraction of the second telescopic cylinder 95, the movable plate 3 moves to the right, so that the first mixing box 4 is located directly above the backfill temporary storage box 6. The mixed material in the first mixing tank 4 is discharged to the backfill temporary storage tank 6. Through the operation of the feeding pump 12, the mixed material in the backfill temporary storage tank 6 is transported to the mine to be backfilled through the discharge pipe 11. During the discharge of the first mixing tank 4, the fourth telescopic cylinder 811 extends, causing the second frustum-shaped guide sleeve 89 to move down and overlap the second frustum-shaped guide head. At this time, the second sealing plate 812 does not close the second feeding port 84. The material at the main feed hopper 813 is transported to the inside of the second mixing tank 5 by the rightward conveying of the bidirectional belt conveyor 82. Then the second mixing tank 5 starts to mix. After the mixing is completed, the fourth telescopic cylinder retracts. Through the retraction of the first telescopic cylinder 94 and the extension of the second telescopic cylinder 95, the movable plate 3 moves to the left, so that the second mixing tank 5 is located directly above the backfill temporary storage tank 6. Then the mixed material in the second mixing tank 5 is discharged to the backfill temporary storage tank 6. This cycle repeats continuously to achieve continuous transportation of the mixed material and improve the backfilling efficiency.
