Description

A kind of screw type earth taking device

technical field

The utility model belongs to the field of agricultural science experiments, in particular to a spiral soil-taking device.

Background technique

Soil collection and analysis are widely used in agricultural production, soil pollution control, animal and plant research, etc. There are also various soil collection tools, and the most commonly used sampling tool is the soil auger. The basic type of the soil drill is cylindrical, and the drill bit at the bottom has an oblique cutting surface to facilitate drilling and cutting the soil. The inner cavity of the cylindrical drill bit collects soil samples, and the collected soil samples are not easy to mix with other layers of soil. But, rely on the cutting edge of cylindrical drill bit front section to carry out chiseling and sliding cutting and drill into the soil layer because this earth borrowing drill relies on the cutting edge of cylindrical drill bit front section completely, need just could finish operation by means of larger external force during use.

At present, there are direct pressure type, spiral type and hammer pressure type for soil borrowing drills. The direct pressure type adopts the method of vertical pressure stabilization to make the sampler enter the soil, which is suitable for the situation where the soil resistance is not large. When the soil texture is hard, the direct pressure type is not easy to work; the gravity hammer type soil drill is hammered by external force, Make the sampler overcome the resistance of the soil and enter the soil. If the center position of the hammer drill tail cannot be stabilized during the hammering process, so that the force generates a bending moment, the service life of the soil drill will be increased; the spiral soil drill adopts direct pressure Rotation mode, but when the rotation force is uneven or cannot be rotated vertically downward stably, the operation is laborious and the drilling efficiency is low, especially when sampling hard, sticky soil and deep soil.

As CN 204228458 proposes a helical earth-borrower, the main rod rotates to drive the drill bit to move vertically and stably upwards or downwards to obtain soil samples, but its structure is complicated, soil-absorbing is laborious and the stability is poor during operation. Therefore, the utility model proposes a spiral soil sample collection device with simple structure, convenient operation and high stability when collecting soil samples.
