Compared with the prior art, the sampling device for detecting the compactness provided by the utility model has the advantages that when sampling is carried out, the substrate 1 is placed and pressed on the ground, an operator holds the chisel rod 21 by one hand to enable the chisel head 22 to be positioned on the ground in the sampling hole 11, holds and slides the handle 31 by the other hand, because the sliding rod 41 is of a prismatic structure, the sliding rod 41 can limit the hammer 3 to rotate, and the hammer head 32 is aligned with the chisel rod 21 along the axial direction of the chisel rod 21, the sliding handle 31 can enable the hammer head 32 to accurately strike one end, far away from the chisel head 22, of the chisel rod 21 along the axial direction of the chisel rod 21, so that the problem that the hammer head 32 of the hammer 3 possibly strikes the hand of the operator for holding the chisel rod 21 when the operator strikes the ground through the hammer 3 and the chisel 2 is solved.

Referring to fig. 2, the connecting member 4 has a degree of freedom to rotate around the chisel rod 21, and the connecting member 4 is rotated to rotate the handle 31 to an angle convenient for an operator to hold, thereby increasing comfort of the operator in operating the handle 31.

As an embodiment of the sampling device for detecting compactness provided by the present invention, please refer to fig. 2, the side wall of the chisel 21 is provided with an annular groove 211 coaxial with the chisel 21, the connecting member 4 is provided with a connecting portion 42, and the connecting portion 42 is rotatably clamped in the annular groove 211, so that the connecting member 4 has a degree of freedom of rotation around the chisel 21.

As an embodiment of the sampling device for detecting compactness provided by the present invention, referring to fig. 2, the annular groove 211 is located at an end of the chisel rod 21 away from the chisel head 22, so as to facilitate an operator to hold the middle of the chisel rod 21.

As an embodiment of the sampling device for detecting compactness provided by the present invention, referring to fig. 2 to 3, the connection portion 42 has an arc-shaped plate structure matching with the annular recess 211, so that the connection portion 42 can be separated from or enter the annular recess 211. When coupling portion 42 is removed, chisel 2 may be operated alone to perform operations such as repairing a cut pilot hole with chisel 2.

Referring to fig. 2, the connecting member 4 has a connecting rod 43 perpendicular to the chisel rod 21, and two ends of the connecting rod 43 are fixedly connected to the connecting portion 42 and the sliding rod 41, respectively. The construction of such a connecting element 4 is relatively simple.

The hammer head 32 strikes the end of the chisel rod 21 remote from the chisel head 22 via the stop cap 5. The stop cap 5 can prevent the connecting portion 42 from coming out of the annular groove 211, thereby ensuring the accuracy with which the hammer head 32 strikes the chisel rod 21, and after the stop cap 5 is removed, the connecting portion 42 can be made out of the annular groove 211, thereby enabling independent operation of the chisel 2.

Referring to fig. 2, the chisel head 22 has an arc-shaped plate structure and the axis of the chisel head is parallel to the chisel rod 21. This allows the loose soil to be collected by chisel head 22, thereby replacing the function of a conventional spoon and reducing the tools required. And the sampled pilot hole is trimmed to a cylindrical shape, this configuration of chisel head 22 facilitates trimming the sampled pilot hole. In this embodiment, the connection between chisel head 22 and chisel rod 21 may be of a tapered configuration.
