[0021] As an embodiment of the present invention, please refer to Figure 8 and Fig. 9 The earth-breaking assembly includes a collar 301, and the collar 301 is sleeved on the bottom ends of the left drill tube 108 and the right drill tube 107. The bottom ends of the left drill tube 108 and the right drill tube 107 are both provided with mounting grooves 304, and a slot 305 is provided on one side inner wall of the mounting groove 304. A plug rod 302 is fixedly arranged in the collar 301, and the plug rod 302 is L-shaped. The plug rod 302 is located in the mounting groove 304, and the end of the plug rod 302 is inserted into the slot 305. The lower surface of the collar 301 is also fixedly provided with earth-breaking blades 303 that are equidistantly distributed in an annular shape, and the direction of the earth-breaking blades 303 is opposite to that of the plug rod 302.

During the insertion process, the limiting strip 111 can push out the soil remaining in the limiting groove 110 to ensure that the left drill barrel 108 and the right drill barrel 107 are closely fitted, and when the left drill barrel 108 is about to be docked with the right drill barrel 107, the docking rod 601 in the left drill barrel 108 will be inserted into the docking tube 603 in the right drill barrel 107 to ensure that the left drill barrel 108 and the right drill barrel 107 are not easily separated after the docking is completed, and it is more convenient to insert into the placement groove 105 of the rotating member 104, which is more convenient to use.

[0026] When in use, the left drill tube 108 and the right drill tube 107 for taking soil can be spliced ​​together and then inserted into the placement groove 105 of the rotating member 104, and the clamping block 109 can be clamped into the clamping groove 106, and then the handle 102 can be held to support the installation tube 101, so that the left drill tube 108 and the right drill tube 107 are aligned with the ground to be sampled, and the double-axis motor 112 drives the block 113 to rotate, and the block 113 drives the rotating member 104 to rotate in the installation tube 101, so that the left drill tube 108 and the right drill tube 107 can rotate together, and at the same time, the impact component can provide a downward impact force for the device, so that the left drill tube 108 and the right drill tube 107 move downward, and the soil to be sampled will be collected in the left drill tube 108. And the right drill barrel 107, and during the rotation of the left drill barrel 108 and the right drill barrel 107, the soil breaking components at the ends of the left drill barrel 108 and the right drill barrel 107 can also play a role of cutting the soil, so that the left drill barrel 108 and the right drill barrel 107 can move downward more quickly, effectively improving the sampling efficiency, and during the sampling process, the supporting component can also play a role of supporting the left drill barrel 108 and the right drill barrel 107, so that the left drill barrel 108 and the right drill barrel 107 can move downward vertically, and the sampling process is more stable.
