Problems solved by technology
The disadvantages of the earth-taking rod of the above-mentioned soil-taking device are: the lower end of the soil-taking rod is a cylinder-shaped structure, and when the soil is removed from the ground, the soil sample is easy to fall off from the cylinder, resulting in the need for multiple soil extractions, and the efficiency is low; and the cylinder-shaped The excavation force is insufficient when sampling the lower end of the structure, and a sampling takes a long time

Embodiment Construction
[0016] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0017] Such as figure 1 , figure 2 As shown, the shallow manual earth-absorbing sleeve structure used for geological exploration in this embodiment includes an earth-absorbing sleeve 1, and the outer wall screw device of the soil-absorbing sleeve 1 has a tight sleeve 2, and the soil-absorbing sleeve 1 has an external thread 11, which is tightly held. The sleeve 2 has an internal thread 21; the lower end of the tight sleeve 2 has a tight ring portion 22, and the inner side of the tight ring portion 22 has a spiral groove 221, and the outer wall of the lower end of the soil collection sleeve 1 is fixedly connected with a guide block 3 to guide The block 3 cooperates with the spiral groove 221. The guide block 3 includes a plurality of and is respectively arranged on the upper and lower parts of the lower end of the soil-absorbing cover 1. ...

The invention relates to a superficial layer manual soil sampling sleeve structure for geological exploration. The superficial layer manual soil sampling sleeve structure for geological exploration comprises a soil sampling sleeve; the external wall of the soil sampling sleeve is provided with a clasping sleeve in a spiral mode; the lower end of the clasping sleeve is provided with clasping ring portion; the internal side of the clasping ring portion is provided with a spiral groove; the external wall at the lower end of the soil sampling sleeve is fixedly connected with a guiding block; the guiding block is matched with the spiral groove. The superficial layer manual soil sampling sleeve structure for geological exploration has the advantages of being simple in structure, reasonable in design and high in working reliability; effectively preventing soil samples separating from the soil sampling sleeve and improving the sampling efficiency due to a partial sealing structure of the clasping sleeve of the soil samples; being convenient to the clasping operation due to the fact that a spiral structure is formed between the clasping sleeve and the soil sampling sleeve.
Description
technical field [0001] The invention relates to the field of geological exploration equipment, in particular to a device for taking soil samples from shallow soil. Background technique [0002] In the field of geological prospecting, earth-borrowers are often used when collecting soil samples. Existing earth extractor structure comprises circular base, and the center of base is fixedly connected with guide seat, and the central sliding device of guide seat takes soil rod, and the soil fetch rod is the structure that the upper end has the screw mandrel lower end that has the soil fetch cover, and the wire The rod is spirally connected in the screw rod seat, and the screw rod seat is fixedly connected with the circular base. The shortcoming of the earth-taking rod of the above-mentioned soil-taking device is that: the lower end of the soil-taking rod is a cylinder-shaped structure, and when the soil is taken off the ground, the soil sample is easy to fall off from the cylinde...
