Preferably, one end of the hydraulic rod is provided with a tip.

Preferably, filter screens are provided in the first air inlet and the second air inlet.

Preferably, the position of the first air inlet is lower than that of the second air inlet.

Compared with the prior art, the beneficial effect of the utility model is: in the utility model, the first air suction pump and the second air suction pump can transfer the air in the soil through the first air inlet and the second air inlet on the hydraulic rod. The gas is pumped to the first air collection bag and the second air collection bag respectively by the gas delivery hose. The gas collection is convenient, and the hydraulic rod can be easily penetrated into the soil under the drive of the hydraulic cylinder. The operation is relatively labor-saving, and the soil gas is also collected. At the same time, it will cause less damage to the land.
