The introduction of earth auger drills

When designing a soil drill, the main problem to be solved is how to reduce the resistance of the soil. During sampling, a soil sampler the cuts soil and is subjected to soil resistance to cutting by the drill, mainly including penetration resistance, friction, and adhesion.

Design Principle of earth auger drills

The traditional method of reducing soil cutting resistance is to reduce adhesion and cutting resistance by reducing the contact area between the soil and the drill bit, thereby reducing soil resistance and achieving the purpose of reducing viscosity and resistance. This method can effectively reduce soil resistance to a certain extent, but the effect is not ideal when encountering relatively hard soil.

The spiral soil sampler uses methods of penetration, soil cutting, soil loosening, soil lifting, and soil dumping to achieve rapid soil collection. The soil drill consists of a sleeve and a spiral drill rod, with the blade end of the spiral drill rod made into a blade shape. During sampling, the sleeve penetrates vertically into the soil under the action of hydraulic pressure, while the spiral drill rod rotates to shred the soil. Under the combined action of the blade and sleeve, the chopped soil is transported to the soil outlet at the top of the sleeve. After the sleeve is lifted, the soil directly enters the collection box through a hose under the action of gravity, thereby completing soil sampling and collection.

The Features of earth auger drills

1. The auger is made of stainless steel and does not contaminate the sample.

2. The earth auger drill adopts a pedal type, which is more convenient, faster, and reduces labor intensity.

In addition, using a spiral soil sampler to collect soil samples has the advantages of full thickness, equal volume, fast speed, and easy operation.
