[0031] Such as figure 1 As shown, the present embodiment provides a soil-taking bag 100, including a bag body 110 selectively connected with a drill bit, the bag body 110 can be an existing bag structure, such as a plastic bag, but is preferably made of aluminum foil Aluminum foil bag, the bag made of aluminum foil is moisture-proof, air-tight, shading and can prevent odor from dissipating, and then can maintain the performance of the soil well, and then ensure the accuracy of the subsequent test results of the collected soil samples.
[0032] Further, the aluminum foil bag adopted is rectangular, which is more convenient to connect with the drill bit 310, and more convenient to collect soil with low moisture content, which can effectively reduce the removal of soil with low moisture content from the soil bag 100 during the process of taking out the drill bit 310. The number and probability of slipping out. However, it is also feasible for aluminum foil bags to adopt other sh...

[0046] join image 3 and Figure 4 , this embodiment provides a soil-taking device 300 , the soil-taking bag 100 of the first embodiment, and the soil-taking bag 100 is placed in a drill bit 310 . The soil bag 100 moves downward along with the drill bit 310, and then collects soil samples.
[0047] Further, the soil removal device 300 also includes a drill bit 310, the structure of the drill bit 310 is the same as that of the existing flat drill bit, but other drill bits in the prior art can also be used.
[0048] Further, the drill bit 310 includes a drill bit body 311 , and a plurality of circulation holes 311 a are opened on the drill bit body 311 . A plurality of circulation holes 311a are provided in order to reduce the gap between the soil bag 100 and the drill body 311, increase the force between the soil bag 100 and the drill body 311, and further prevent the drill body 311 from dislodging the soil bag during the movement. 100 comes off from the drill bit body 311, ...

[0055] This embodiment provides a method for taking soil by using the soil taking device of the second embodiment, comprising the following steps:
[0056] Place the soil bag with a retractable open end in the drill bit, and connect the soil bag with the drill bit; then turn the drill bit to collect soil samples, shrink the open end of the soil bag, lift the soil drill together with the soil bag out of the ground, and The soil bag is removed from the drill bit.
[0057] The connection between the soil bag and the drill bit is that the soil bag is placed inside the drill bit, and at the same time the lower edge of the open end of the soil bag is turned out, wrapped around the lower edge of the drill bit and fixed.
[0058] The open end of the soil-absorbing bag is to pull the ring of the soil-absorbing bag above the ground tightly after the drill bit reaches the specified layer depth, so that the soil-absorbing bag located in the underground part is pulled by the pulling part o...
