Problems solved by technology
The disadvantages of the above-mentioned soil fetching device are: the lower end of the soil fetching 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, which is inefficient
The applicant has applied for a patent titled "Soil Taker Rod for Soil Taker", which uses a tapered sleeve structure to solve the problem of the sample falling out of the cylinder. Deformation, after deformation, the holding force on the sample decreases, and the sampling resistance increases

Embodiment Construction
[0018] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0019] Such as figure 1 As shown, the drilling-type earth-absorbing rod of the present embodiment comprises an earth-absorbing rod body 1, and the earth-absorbing rod body 1 has a structure with an upper screw rod 11 and a lower soil-absorbing cover 12, and the lower end of the soil-absorbing cover 12 is connected Taper cover 13 is arranged, and the outer wall of soil-taking cover 12 is fixedly connected with drilling head cover 14.
[0020] Such as figure 2 As shown, the inner diameter of the lower end of the tapered sleeve 13 is smaller than the inner diameter of the soil-taking sleeve 12, forming a wrapping structure to prevent the sample from falling off; in order to further strengthen the wrapping ability of the tapered sleeve 13, the tapered sleeve 13 is set as a conical spring , the spring wire section of the conical spring is pr...

The invention relates to a drilling type soil sampling rod. The drilling type soil sampling rod comprises a soil sampling rod body. The soil sampling rod body is provided with a structure with a lead screw at the upper portion and a soil sampling cover at the lower portion. A conical cover is connected to the lower end of the soil sampling cover. The outer wall of the soil sampling cover is fixedly connected with a drilling head cover. The drilling type soil sampling rod is simple in structure and reasonable in design. The lower end of the soil sampling cover is connected with the conical cover, a soil sample is prevented from disengaging from the soil sampling cover, one-time sampling is achieved, the sampling efficiency is improved, the outer wall of the conical cover is sleeved with the soil drilling head cover, the protection of the conical cover is achieved, and the sampling efficiency is improved.
Description
technical field [0001] The invention relates to the field of geological prospecting equipment, in particular to an earth taker. 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 disadvantages of the above-mentioned soil fetching device are: the lower end of the soil fetching 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 ...
