Technical Field

[0001] The utility model relates to the field of frozen soil excavation, in particular to a lightweight portable pressure-compensated frozen soil electric excavator. Background Art

[0002] Currently, traditional soil augers are widely used, but they have some unsatisfactory aspects: manual soil augers have poor soil sampling effects, are very laborious, have very low work efficiency, and are difficult to sample frozen soil; handheld electric soil augers or small soil drilling rigs are unreliable, have poor safety and low accuracy, have high operating costs, and require a lot of financial resources; large hydraulic or pneumatic soil drilling rigs are expensive and difficult to use for large-scale sampling of farmland.

[0003] There are several disadvantages and shortcomings of using a soil drill when taking soil from frozen soil:

[0004] 1. For frozen-thaw soil with high strength, high hardness and a freezing depth of less than 2m, in high-altitude cold areas, the frozen soil cannot be manually removed.

[0005] 2. Small handheld electric soil drills use hammer or rotary twist drilling methods, which require high physical strength of the operator and destroy the physical structure of the soil.

[0006] 3. Large hydraulic or pneumatic soil drills have low field walking and operation efficiency for plots of farmland with complex soil conditions, sloping farmland covered with ice and snow, etc.

[0007] 4. Large hydraulic or pneumatic soil drilling rigs are mostly used for drilling and sampling of engineering geological exploration, engineering frozen soil, roads, groundwater, etc. They are large in size and heavy in weight, which will compact the cultivated layer of farmland soil and destroy the physical structure of the soil.
