The sealing plates 4 can move left and right along the base 1. The right sealing plate 4 is provided with a movable hole, and a sliding seat 5 is provided at the movable hole. A slidable spraying pipe 6 is inserted into the sliding seat 5. A spraying head 7 is provided at one end of the spraying pipe 6 inside the steel pipe 3. Several nozzles 8 are evenly distributed around the spraying head 7. The other end of the spraying pipe 6 outside the steel pipe 3 is connected to a storage tank 9 through a hose 22. A booster air pump 10 is connected to the storage tank 9.

[0021] The sliding seat 5 has sliding aids at its two ends, and the sliding aids are arranged in close contact with the side wall of the spray pipe 6.

[0022] The sliding aid includes a shaft 11 and a guide bearing 12 sleeved on the shaft 11. The sliding seat 5 is provided at its end with a first mounting groove 13 and a second mounting groove 14 for accommodating the shaft 11 and the guide bearing 12.
