Abstract

An in-situ fixed layered soil sampler relates to a soil layered sampler, which solves the problems of time-consuming and labor-intensive operation of the existing soil sampler and poor sampling effect caused by easy deviation of sampling points. Its rotating armrest is fixed on one end of the screw rod, which is used to drive the screw rod to rotate along the central axis of the screw rod. The center of the end of the ring knife is fixed on the other end of the screw rod. The through hole is set on the screw rod; N base supports are evenly distributed and fixed on the bottom surface of the base, and N is an integer greater than or equal to 3. The utility model is suitable for soil sampling.

Description

An in-situ fixed soil layer sampler

technical field

The utility model relates to a layered soil sampler.

Background technique

In disciplines such as biology, agronomy, ecology and environmental science, often need to collect natural soil and carry out research, this just needs to adopt soil stratified sampler to carry out sampling, but existing soil stratified sampler has following shortcoming: 1 1. It is time-consuming and labor-intensive to rely entirely on the user to press down vertically and rotate the sampler during operation; 2. When taking clay soil samples, it is necessary to tap the sampler with a blunt instrument such as a hammer to take soil, which is easy to use 3. During stratified sampling, due to the continuous rotation of the operator, the sampling point is prone to shift, and the soil around the sampling point is likely to fall into the predetermined sampling hole for sampling, resulting in poor soil sampling effect.

Utility model content

The utility model aims to solve the problems of time-consuming and labor-intensive operation of the existing soil sampler and poor sampling effect caused by easy deviation of sampling points, thereby providing an in-situ fixed soil layered sampler.

An in-situ fixed soil layer sampler, which includes a screw sampler, a base and N base supports, the screw sampler includes a rotating armrest, a screw rod and a ring knife, and the rotating armrest is fixed on one end of the screw rod , used to drive the screw rod to rotate along the central axis of the screw rod, the center of the end of the ring knife is fixed on the other end of the screw rod, a through hole is opened in the center of the base, and the base is sleeved on the screw rod through the through hole; N The base brackets are evenly distributed and fixed under the base, and N is an integer greater than or equal to 3.

Beneficial effects: when the utility model is in use, the base bracket is fixed to the surface of the soil to be sampled, and the operator drives the screw rod through the rotating handrail, so that the ring knife is screwed into the soil layer, and after reaching the depth to be sampled, the rotating handrail is reversely rotated, thereby obtaining Soil sample. The utility model saves time and labor, and the sampling point is not easy to deviate, and the sampling effect is good.

Detailed ways

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 1. In conjunction with FIG. 1 , this particular embodiment is described. An in-situ fixed soil stratified sampler includes a spiral sampler, a base 4 and N base supports 5, and the spiral sampler includes a rotating handrail 1 , screw rod 2 and ring knife 3, described rotating armrest 1 is fixed on one end of screw rod 2, is used to drive screw rod 2 to rotate along the central axis of screw rod 2, and the end center of ring knife 3 is fixed on the other end of screw rod 2 On one end, a through hole is opened in the center of the base 4, and the base 4 is set on the screw rod 2 through the through hole;

When the utility model is in use, the base bracket is fixed to the surface of the soil to be sampled, and the operator drives the screw rod through the rotating handrail, so that the ring knife is screwed into the soil layer, and after reaching the sampling depth, the rotating handrail is reversely rotated to obtain soil samples. The utility model can effectively reduce the labor intensity, greatly improve the work efficiency, and the sampling is accurate, thereby reducing the experimental error, and it is not necessary to use hammers and other instruments to strike the clay soil sampling, which reduces the loss of the instruments and prolongs the service life of the ring knife by 30 %.

Embodiment 2. The difference between this embodiment and the in-situ fixed layered soil sampler described in Embodiment 1 is that it also includes a casing 6 with an internal thread. The sleeve 6 is threadedly connected with the screw rod, and the lower surface of the sleeve 6 with internal threads is fixedly connected with the upper surface of the base 4 .

The casing 6 with internal threads in this embodiment can effectively make the screw rod 2 in a vertical state, ensuring more accurate positioning of the soil-taking point.

Specific embodiment three, the difference between this specific embodiment and a kind of in-situ fixed soil layer sampler described in specific embodiment two is that it also includes M fixed cones 8 and M backguy wires 7, the M root One end of the stay wires 7 is evenly distributed and fixed on the side of the sleeve 6 with internal thread, the other ends of the M stay wires 7 are fixedly connected with the ends of the M fixing cones 8, and M is an integer greater than or equal to 3.

In this embodiment, M fixed cones 8 are fixed around the soil layer at the position to be sampled to further ensure more accurate positioning of the soil sampling point.
