Description

Technical Field

[0001] The utility model relates to the technical field of ecological environment inspection, in particular to a hard soil sampler with stable support. Background Technique

[0002] During the process of ecological environment detection, it is often necessary to detect the soil in various places, so a soil sampler is often used for sampling.

[0003] The patent document with the publication number of CN221238678U discloses a soil sampler, which includes a support frame, a downward pressure sleeve, a sampling cylinder and a hand wheel. The downward pressure sleeve is threadedly connected to the support frame. The top of the sampling cylinder is fixedly connected to the bottom end of the downward pressure sleeve, and the hand wheel is fixedly connected to the outer wall of the downward pressure sleeve. For this soil sampler, rotate the support legs, insert the support legs into the soil, and rotate the hand wheel to drive the downward pressure sleeve and the sampling cylinder to rotate, so that the sampling cylinder on the downward pressure sleeve can rotate and move downward to sample the soil. After sampling, move the sampling cylinder upward, and then perform sample extraction. The movable rod can drive the soil discharging plate to move downward, so that the soil discharging plate can extract the soil sample in the sampling cylinder, thus playing the role of facilitating sample extraction. However, the following problems still exist in the actual use of this patent:

[0004] This sampling device inserts the support legs into the soil and rotates the hand wheel to make the sampling cylinder rotate and move downward to sample the soil. However, when sampling hard soil, the symmetric support legs are difficult to insert into the soil quickly and stably at the same time, resulting in the situation that the sampler tilts, and it is difficult to accurately moisten the position of the sampled soil, resulting in poor support stability. Moreover, it is difficult to form an impact on the soil during the sampling process, resulting in great difficulty in sampling hard soil. Therefore, the use of this soil sampler is relatively inconvenient.

[0005] A hard soil sampler with stable support is proposed to solve the problems mentioned above. Content of the Utility Model

And through the setting of the water storage cavity 12, when sampling hard soil, it is convenient to inject a certain amount of water along the position of the notch 2, so as to improve the efficiency of softening the soil and reduce the waste of water resources at the same time. Therefore, the practicability of this sampler is stronger.
