With this arrangement, the sliding effect is more stable.

[0034] See also Figure 4 , Figure 6 , Figure 7 , Figure 8 , a first driving assembly for driving the sliding mounting arm 4 to slide is provided. In one embodiment, the first driving assembly includes two first racks 9, and the two first racks 9 are fixedly arranged on the left and right sides of the warehouse body 1 in the front-to-back direction by threaded connection or welding.

The chain 23 is wound between the first sprocket 21 and the second sprocket 22. In this way, the third motor 24 drives the suction pipe 20 to rotate by the transmission of the chain 23, which has a stable effect and high efficiency.

[0040] See also Figure 2 , Figure 5 In one embodiment, the cross-section of the lower side of the suction plate 25 is annular.

[0042] S1. Open the electric shutter door 2, a forklift transports two rows of eight crucibles 28 filled with materials and places them in the warehouse 1, and then the forklift exits and the electric shutter door 2 is closed;

[0043] S2. The sliding mounting arm 4 moves forward under the drive of the first driving assembly, so that the four suction plates 25 arranged in parallel along the left and right directions are respectively aligned with the four crucibles 28 in the first row;

[0044] S3. The second drive member drives the mounting portion 13 to descend, and at the same time the third drive assembly drives the suction pipe 20 to rotate, so that the suction plate 25 rotates and descends, gradually extending into the crucible 28 to break up and absorb the material;

[0045] S4. After the first row of the crucible 28 is discharged, the mounting portion 13 rises and then moves forward so that the four suction plates 25 are aligned with the four crucibles 28 in the second row, and then dropped to break and absorb the material;

[0046] S5. After the second row of crucibles 28 are discharged, the suction plate 25 rises and retreats back to the initial position, waiting for a new batch of crucibles 28 to enter.
