Description

Technical Field

[0001] The utility model relates to the field of soil detection equipment, in particular to an autonomous portable soil compactor. Background Art

[0002] The compactor is a construction equipment that uses hammering to determine the optimum moisture content and maximum dry density of soil, providing a basis for evaluating the degree of soil compaction.

[0003] The traditional compactor includes a body, a compacting hammer installed on the body, and a test barrel for soil samples. The test barrel is cylindrical. After the test barrel is installed on the compactor, the compacting hammer is controlled to hammer the soil in the test barrel. Soil samples with different water contents are hammered respectively, and the corresponding dry capacity is measured to obtain the maximum dry capacity and the optimal water content. However, the overall structure of the traditional compactor equipment is complex and the cost is high. After completing a compaction, the compacting hammer needs to be lifted manually, resulting in low efficiency. Due to changes in the site during the test, the balance of the equipment cannot be accurately guaranteed, resulting in the dispersion of the force of the compacting hammer during the compaction process, and even the test barrel is damaged. It is impossible to perform testing simultaneously during the compaction process, which is inefficient. Traditional compactors are large in size and are inconvenient to carry during work tests, resulting in the inability to test in time after sampling, affecting the overall efficiency and results.

[0004] In order to solve the above problems, a self-contained and portable soil compactor is needed. Utility Model Content
