Description

Technical Field

[0001] The utility model relates to the field of soil sampling, in particular to a soil sampling device with noise reduction effect. Background Art

[0002] The soil sampling device with noise reduction effect usually obtains soil samples by drilling. The drilling technology involves the design of the borehole, the selection of the drill rod and the drill bit, the control of the drilling parameters, etc., which all have an impact on the performance and effect of the soil sampling device with noise reduction effect. Referring to the patent number of a known soil sampling device with noise reduction effect: (CN218470213U), there are at least the following defects in the process of use:

[0003] 1. When the device is sampling, if the humidity or viscosity of the soil is high, it is easy for it to adhere to the inner wall of the sampling tube, thereby blocking the tube and making it impossible to smoothly remove the soil. External force is required to remove the soil sample. This operation does increase the extra workload and operational complexity, thereby reducing the practicality of the device.

[0004] 2. After the sampling operation, a certain amount of soil will remain in the device. The residual soil adheres to the inner wall, corners and hidden parts of the device, making the cleaning work difficult and impossible to completely remove.

[0005] 3. When the device is used for sampling, users may encounter excessive noise. The noise mainly comes from the operation of the sampling device and the vibration generated when it comes into contact with the earth's crust. Due to the high decibel level of the noise, it may have an adverse effect on the comfort of the work site and the surrounding environment. Utility Model Content
