[0057] With such a design, the barbed plate 33 is designed as a continuous circle and is fixedly connected to the inner wall of the second-level shovel barrel 3. When the sandy soil is lifted after entering the first-level shovel barrel 2, the design of the barbed plate 33 of the inverted cone 31 makes it difficult for the sandy soil to fall off.

[0058] In one embodiment, the fastening mechanism includes:

[0059] A connecting component, arranged on the shovel rod 1;

[0060] A matching component, arranged on one side of the first-stage shovel barrel 2 close to the shovel rod 1, and used to cooperate with the shovel rod 1 for connection.

[0061] In one embodiment, the connecting component includes:

[0062] A threaded column 12, arranged on the shovel rod 1;

[0065] With such a design, one end of the threaded column 12 is fixedly connected to the shovel rod 1; the other end is fixedly connected to the connecting rod 11.

[0066] In one embodiment, the limiting member includes:

[0067] A limiting ring 13, sleeved on the threaded column 12;

[0068] A connecting head 14, arranged on the connecting rod 11 and rotatably connected to the connecting rod 11.

[0069] With such a design, the limiting ring 13 is sleeved on the threaded column 12.

[0070] In one embodiment, the matching component includes:

[0071] A connecting frame 25, arranged on the first-stage shovel barrel 2;

[0072] A connecting ring 26, sleeved on the threaded column 12 and threadedly connected to the threaded column 12, and the side far from the connecting frame 25 abuts against the limiting ring 13;

[0073] A matching part, arranged on the first-stage shovel barrel 2.

[0074] With such a design, one end of the connecting frame 25 is fixedly connected to the first-stage shovel barrel 2, and the other end is fixedly connected to the connecting ring 26.

[0075] In one embodiment, the matching part includes:

[0076] A relief groove 21, arranged at one end of the first-stage shovel barrel 2 close to the connecting rod 11;

[0077] A matching groove 22, arranged on the first-stage shovel barrel 2 and communicating with the relief groove 21, and is inserted into the connecting head 14 in a matching manner;

[0078] A fixing block 23, arranged on the relief groove 21 and distributed on both sides of the connecting head 14;

[0079] The fastening bolts 24 are arranged on the fixing block 23 .

[0080] With this design, the fixing block 23 is fixedly connected to the clearance groove 21.

[0081] In one embodiment, the connector 14 is provided with a mounting hole 15 for mounting the fastening bolt 24 .

[0082] With this design, hold the shovel handle 1, rotate the connecting head 14, the connecting rod 11 and the threaded column 12, and pass the connecting head 14 and the connecting rod 11 through the connecting ring 26, and the threaded column 12 is threadedly connected to the connecting ring 26. Since the connecting rod 11 and the connecting head 14 are rotatably connected, when the connecting rod 11 rotates, the connecting head 14 is driven to horizontally enter the matching groove 22, and then the fixing block 23 and the connecting head 14 are connected and installed by the fastening bolts 24. At this time, the connecting head 14 and the fixing block 23 are connected, the threaded column 12 and the connecting ring 26 are threadedly connected, and the shovel handle 1 and the secondary shovel barrel 3 are installed and connected, and are not easy to separate when taking soil.

[0083] Working principle: When in use, the coring mechanism still has the ability to perform coring when encountering wet and saturated sand and soil, so as to continue drilling; the fastening mechanism enables the shovel rod 1 and the first-level shovel barrel 2 to be fastened and installed to avoid disconnection when taking soil.
