The telescopic mechanism 1 comprises a sleeve 5, a piston 7 arranged in the sleeve 5 and a push rod 6 inserted into the sleeve 5; one end of the push rod 6 is fixedly connected with the piston 7, and the other end of the push rod is connected with one end of the hydraulic rod 4 arranged side by side on the same pin shaft; one end of the sleeve 5 is sleeved with the push rod 6, the other end of the sleeve is connected with the other end of the hydraulic rod 4 arranged side by side on the same pin shaft, both ends of the sleeve 5 are provided with a water inlet 10 and a water outlet 13, a first one-way valve 11 is arranged at the water inlet 10, and a second one-way valve 12 is arranged at the water outlet 13; the water tank 3 is connected with a first one-way valve 11 through a pipeline, and the spray pipe 2 is connected with a second one-way valve 12 through a pipeline. Wherein the first one-way valve 11 allows water flow from the water inlet pipe 8 into the sleeve 5 and prevents water flow back; the second one-way valve 12 allows water flow from inside the sleeve 5 into the outlet pipe 9 and prevents water flow back.

As shown in fig. 1 and 4, two spraying pipes 2 connected with the telescopic mechanism 1 are arranged below the cantilever 15 of the excavator side by side, a plurality of spraying heads 16 are further arranged on the spraying pipes 2, and the spraying heads 16 on the spraying pipes 2 on two sides are arranged at 45 degrees outwards, so that uniform spraying of water mist is ensured, the coverage area is wide, and dust raising of particles such as coal dust and dust is effectively inhibited.

As shown in fig. 3, a sealing ring (not shown) is provided between the piston 7 and the inner wall of the sleeve 5 to block the inner cavity of the sleeve 5 into left and right chambers. A sealing ring 14 is also arranged at the connection of the sleeve 5 and the push rod 6 to ensure that the telescopic mechanism 1 does not leak during operation.

When the utility model is used, the hydraulic rod 4 drives the cantilever 15 of the excavator to move and simultaneously drives the telescopic mechanism 1 to reciprocate, and the one-way valve 11 at the water inlet 10 allows water flow to enter the sleeve 5 from the water inlet pipe 8 in the reciprocating process of the telescopic mechanism 1, so that the water flow is prevented from flowing back. Likewise, the one-way valve 12 at the outlet 13 allows water flow from inside the sleeve 5 into the outlet pipe 9, while preventing water flow back.
