Each time it rotates, the stab tube 11 is changed by one to reach the lowermost end, and when the lowermost stab tube 11 is inserted into the soil, the soil at that position enters the digging chamber 28, and the elevating ring 34 Is pushed and moved upward, whereby the resistance spring 35 accumulates elastic position energy, and at this time, the valve 32 abuts on the inner wall of the inner ring of the elevating ring 34, moves in synchronization with the elevating ring 34, and returns. In the process of storing elastic position energy in the spring 30, opening the drain hole 33, flowing the chemical solution in the water pipe 27 into the soil from the drain hole 33, and moving the elevating ring 34 upward, the length of the chain rod 31 is increased. Since it is a constant value, in order to avoid interference of the chain rod 31 in the process of moving the elevating ring upward, it is rotated 60 degrees, and the power sequentially rotates the crossing plate 41 through the connecting cylinder 36 and the connecting rod 39. The cross-cutting plate 41 is spread outward along the fixed shaft 42 based on the trajectory of the slide rail 45, crosses the soil in the outer portion of the piercing pipe 11, cuts the surface layer of the entire soil from the intermediate portion, and loosens the inside. The resistance spring 35 and the return spring 30 can be returned by the elastic restoring force of the spring, and the elevating ring can be returned because there is no restriction on the soil when the piercing pipe 11 at the lowermost end is rotated to the outside of the soil to provide convenience for air flow. The 34 and the valve 32 are interlocked with each other to move downward, and at the same time, the main bevel gear 22 meshes to rotate the sub-bevel gear 21, and the power is sequentially driven by the driven shaft 24, the rotary tub 25, the corrugated annular groove 23, and the like. The rake 16 is interlocked with the slide rod 17 and slid to the left and right to return the soil taken out to the piercing tube 11.

The beneficial effect of the present invention is: The present invention utilizes a piercing configuration that is coaxial with the wheels, can complete the process of piercing and digging up the soil in the process of movement, does not require any other power, is eco-friendly and has strong continuity. The soil enters the empty pipe and pushes the empty pipe to move it, which is used as a condition to trigger the addition of the chemical solution across the soil near the piercing pipe, and automatic improvement for the soil can be realized, and the ring shape Utilizing the water storage chamber and the water pipes distributed in a ring shape, there is a chemical solution only in the lowermost water pipe, and the amount of the chemical solution is the same as the volume of the water pipe each time, realizing quantification and accuracy of the chemical solution injection. It is possible to improve the soil improvement effect, move forward only by pushing the equipment manually, pierce the soil and dig it up, and add chemicals to the soil to improve it, it is convenient to operate, only one step You can work with.

According to the above method, an engineer in this field can make various changes depending on the operation mode within the scope of the present invention.
