The power mechanism drives the third shaft 9 to rotate in a reciprocating manner, the power mechanism is a motor after being connected with a power supply, and an output shaft of the motor drives the third shaft 9 to rotate in a reciprocating manner;

the connecting ring 17, the swing arm III 18 and the swing arm IV 19 on the shaft III 9 synchronously reciprocate at any time, and the two shift levers 20 can synchronously swing through the arrangement of the shift levers 20 on the swing arm III 18 and the swing arm IV 19.

Through the reciprocating synchronous swing of the two shift levers 20, the first swing arm 10 can realize reciprocating swing by taking the third shaft 9 as a rotation center, when the first swing arm 10 is rotated to a vertical state from an inclined state, the second swing arm 11 can adaptively rotate with the first step and tend to the vertical state, and at the moment, the lifting block 13 can overcome the elasticity of the third compression spring 15 to drive the lifting inserted link 14 and the sampling system 16 on the lifting inserted link 14 to synchronously move downwards; the lifting block 13 is limited by the frame structure of the limit frame 12, and can only slide in the limit frame up and down.

When the first swing arm 10, the second swing arm 11 and the lifting block 13 are positioned at the same vertical straight line in the vertical direction, the lifting inserted rod 14 drives the sampling system 16 to descend to the lowest position, and the sampling system 16 positioned at the lowest position is completely immersed into soil to be sampled;

thereby completing the sampling operation of the soil layer in the target area.

By providing the auxiliary device, the soil to be excavated by the sampling system 16 can be pre-treated, so that the soil in the area can be excavated more easily.

Refer to fig. 2 and 3.

When the lifting block 13 is lifted, the lifting plate 27 is lifted synchronously under the driving of the transmission rod 26, and since the lifting plate 27 and the corresponding screw rod one 28 and screw rod two 29 are both in limited rotational connection, that is, the screw rod one 28 and screw rod two 29 can rotate on the corresponding lifting plate 27, and cannot move axially in the vertical direction relative to the lifting plate 27.

In this embodiment, the bottom of triangular prism housing 21 is constantly higher than the upper surface of spiral rotary tillage arm 302, and the two will not collide or be restricted in movement. And spiral rotary tillage arm 302 is the spiral structure, can realize more efficient excavation operation.

Through transmission's setting, can carry out adaptability collaborative operation with excavating and collecting the holistic removal of shell 1, collect shell 1 promptly when static, can realize the sample operation to soil, and when collecting shell 1 and remove, make sampling system 16 break away from the contact with soil for remove and sample and excavate and can not mutual interference.

Refer to fig. 2 and 3.

With the continuous upward movement of the second screw 29, the teeth on the first conical gear 35 are finally contacted with the teeth on the second conical gear 36 to complete the transmission engagement; the second conical gear 36 drives the first shaft 3 to rotate on the collecting shell 1 along with the first conical gear 36, and due to the arrangement of the second pressure spring 34, the first conical gear 35 can still keep continuous contact after being in contact and meshed with the second conical gear 36 until the second pressure spring 34 cannot be compressed and deformed.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
