Description

Technical Field

[0001] The utility model relates to the technical field of soil sample collection, in particular to a soil sample collection device for land engineering. Background Art

[0002] Soil sample collection is an important task in land survey, and its purpose is to investigate the changes in the soil environment. At present, most of the existing soil sample collection devices use a motor to drive the drill rod to drive the drill bit to drill holes into the soil for sampling. Since the sampling device itself does not have a sampling function, after the drill bit is used to drill the hole, the personnel still need to hold a special straight-rod soil sampler and extend it into the hole to sample the soil, which seriously affects the efficiency of the sampling work.

[0003] The existing stratified soil sample collection device with publication number CN219495705U mainly includes the addition of a collection tube, a cone head, a connecting block, a fixed inner screw ring, a threaded rod and a limiting sleeve. Our design improvements and actual use have shown that the device has good practicality, is easy to operate, is convenient for collecting and using deep soil, has a reasonable structure, and is conducive to promotion.

[0004] The current sampling device has been gradually found to have the following defects during use:

[0005] (1) The above-mentioned soil collection device can only be used in some areas with soft soil. However, in some areas with hard soil, this soil collection device cannot collect soil and needs to carry other devices to cooperate. It is very inconvenient for the staff to carry multiple devices. At the same time, this collection device has low applicability and cannot meet people's needs.

[0006] (2) Due to the limited length of the collection drill bit, the distance between the traditional collection drill bit and the ground is fixed, and thus the collection depth of the soil is also fixed, and the depth of soil collection cannot be adjusted. Utility Model Content
