[0025] The driving assembly 8 includes a crank 801, a third gear 802 and a fourth gear 803. The crank 801 extending to the front side of the rectangular block 4 is rotatably connected in the second inner cavity 6. The third gear 802 located in the second inner cavity 6 and meshing with the second gear 703 on the left side is fixedly connected to the outer side of the crank 801. The fourth gear 803 meshing with both the third gear 802 and the second gear 703 on the right side is rotatably connected in the second inner cavity 6. The third gear 802 and the fourth gear 803 have the same number of teeth and module.

[0026] By turning the crank 801, the third gear 802 is driven to rotate. Since the third gear 802 is meshed with the fourth gear 803 and has the same number of teeth and module, the third gear 802 and the fourth gear 803 rotate synchronously in opposite directions.

[0027] The transmission assembly 7 includes a transmission rod 701, a first gear 702 and a second gear 703. The rectangular block 4 is internally rotatably connected with transmission rods 701 that are symmetrically distributed and extend into the first inner cavity 5 and the second inner cavity 6. The outer sides of the transmission rods 701 are fixedly connected with first gears 702 that are located in the first inner cavity 5 and mesh with the corresponding rack 301. The first gears 702 and the limit stopper 302 are both adapted. The outer sides of the transmission rods 701 are fixedly connected with second gears 703 that are located in the second inner cavity 6.

[0028] The third gear 802 and the fourth gear 803 rotate synchronously in opposite directions. The third gear 802 and the fourth gear 803 are respectively meshed with the corresponding second gear 703, and then the first gear 702 is driven to rotate synchronously in opposite directions through the transmission rod 701;

[0031] Working principle:

[0032] Step 1: By turning the crank 801, the third gear 802 is driven to rotate. Since the third gear 802 is meshed with the fourth gear 803 and has the same number of teeth and module, the third gear 802 and the fourth gear 803 rotate synchronously in opposite directions.

[0033] Step 2: The third gear 802 and the fourth gear 803 rotate synchronously in the opposite direction. The third gear 802 and the fourth gear 803 are respectively meshed with the corresponding second gear 703, and then the first gear 702 is driven to rotate synchronously in the opposite direction through the transmission rod 701;

[0034] Step 3: The first gear 702 rotates synchronously in the opposite direction. The first gear 702 meshes with the rack 301 to drive the infiltration chamber 2 to move upward or downward. When the infiltration chamber 2 moves downward, the lower end of the infiltration chamber 2 can be vertically inserted into the soil, and the infiltration chamber 2 will not shake left and right during the insertion process, thereby avoiding damage to the soil layer structure, thereby ensuring the accuracy of the obtained data.
