The invention provides an inverted soil sampler, which has the advantages of keeping an undisturbed soil sample, having high sample preparation efficiency, improving the soil drilling strength and speed, weakening drilling-in and pulling-up negative pressure and the like.
In order to solve the technical problems, the invention adopts the following technical scheme:
an inverted soil sampler comprises a sampling tube, an outer sleeve, a handle, a connecting rod, a connecting ring and an arc-shaped blade head.
As a first preferred scheme of the invention, the outer sleeve is directly sleeved on the sampling tube, the lower end part of the outer sleeve is connected with the middle end part of the back surface of the arc-shaped blade through the connecting ring, the arc-shaped blade can rotate by means of the plane of the connecting ring, the upper end part of the sampling tube is connected to the upper end part of the arc-shaped blade through the connecting rod, and the control of the rotation position of the arc-shaped blade is realized through the movement of the vertical position of the sampling tube.
As a second preferred scheme of the invention, the handle of the soil sampler is divided into a bulldozer handle, a sampling tube handle and an outer sleeve handle, wherein the number of the outer sleeve handles is two, the two outer sleeve handles are symmetrically welded on two sides of the outer sleeve, and the number of the bulldozer handle and the number of the sampling tube handle are one.
As a third preferred scheme of the invention, the curved blades of the soil sampler are serrated, the number of the curved blades is 4 and the curved blades are symmetrically arranged on the outer side of the outer sleeve, the number of the connecting rods and the connecting rings are 4, the connecting rods and the connecting rings are symmetrically connected with the upper end parts of the sampling tube and the upper end parts of the curved blades, when soil is drilled, the upper end parts of the curved blades are tightly attached to the outer sleeve wall, and when the soil is pulled up, external force is applied to the curved blades so that the plane of the upper end parts of the curved blades outwards rotates and is far away from the outer sleeve wall.
The beneficial effects of the invention are as follows:
1. the outer sleeve is sleeved on the sampling tube, so that the operation is convenient, and the outer sleeve can effectively protect undisturbed soil samples from disturbance;
2. according to the bulldozer handle, the sampling tube handle and the outer sleeve handle, the three handles respectively play different roles in the operation stage, the labor division is clear, and the soil sample collection quality can be effectively improved;
3. the arc-shaped blade can effectively resist the friction force of the contact surface of the soil sampler and soil, can improve the soil drilling strength and speed during soil drilling, can slow down the negative pressure at the end part of an upward pulling test during upward pulling, and can reduce the penetration and upward pulling difficulty;
4. the invention has simple and clear manufacturing principle, convenient operation and better popularization and development prospect.
