Description

Technical Field

[0001] The present application relates to the technical field of soil sampling equipment, and in particular to a soil improvement sampling device. Background Art

[0002] Soil improvement is one of the main research projects of our unit at present. Before implementing soil improvement, we need to fully understand the soil conditions, and then we can formulate corresponding improvement plans according to local conditions. The basic step to understand the soil conditions is soil sampling.

[0003] After searching, the patent with Chinese patent authorization announcement number CN220188051U discloses a soil improvement sampling device, including a base plate, a bearing platform for operators to stand on the top of the base plate, and a guide sleeve is respectively provided at the four top corners of the bearing platform.

[0004] The soil improvement sampling device in the above patent has the following deficiencies: although the device uses the operator's own gravity as the downward pressure, the operator only needs to operate the soil sampling sleeve to rotate when sampling, which greatly saves the operator's physical strength. However, due to the operator's own weight and the long-term stretching and compression of the spring, the metal fatigue of the spring will be accelerated, which increases the cost of use. In addition, the device also requires the operator to manually operate the soil sampling sleeve to rotate. When the soil is hard, the soil sampling cannot be completed in a short time, which reduces work efficiency and can further save the operator's physical strength. Utility Model Content
