Description

Technical Field

[0001] The present invention belongs to the technical field of soil sample collection, and particularly relates to a soil sample collection device and a usage method for mobile sand dunes. Background Art

[0002] Soil sample collection from mobile sand dunes plays an important role in agricultural production and environmental assessment. It not only helps farmers understand the soil nutrient status, formulate scientific fertilization plans, and increase crop yields, but also helps environmental scientists evaluate soil pollution and formulate environmental protection measures to ensure ecological security. Therefore, it is very necessary to regularly collect and analyze soil samples from mobile sand dunes.

[0003] Existing methods for collecting soil samples from mobile sand dunes include: soil drill sampling, Luoyang shovel sampling, soil sampler sampling, and spade pit sampling. The principles of collecting soil samples using soil drills, Luoyang shovels, soil samplers, etc. are basically similar. They all use tools with a bucket-shaped lower end to insert into the target soil layer to collect soil. However, due to the low water content and very loose sandy soil in mobile sand dunes, first, it is very difficult to fix the pit wall, resulting in the inability to accurately obtain samples at the target depth; second, it is difficult to temporarily store the mobile sandy soil in the soil collection container of the above devices and it is not easy to be taken out of the pit. Although spade pit sampling can better obtain samples at the target depth, because it is difficult to form a pit wall in mobile sand dunes, it is often necessary to dig a large area of soil pits, resulting in waste of manpower and time. Summary of the Invention

[0004] In view of the above problems, the object of the present invention is to provide a soil sample collection device and a usage method for mobile sand dunes. Through the fixed cylinder and the soil collection cylinder, the processes of forming a soil collection pit, sampling, etc. can be continuously realized without interruption, shortening the construction time, and only one person is required to operate, which can effectively reduce the labor force.

[0005] The technical solution of the present invention is as follows: A soil sample collection device for mobile sand dunes, including a fixed cylinder. The fixed cylinder is a cylindrical shell structure, the interior of the fixed cylinder is hollow, and a soil collection bucket is arranged inside the hollow part. The soil collection bucket is a cylindrical shell structure, the interior of the soil collection bucket is hollow, and a sampling movable drill bit is arranged at the bottom of the hollow part. An artificial rotation handle for the soil collection cylinder is arranged at the upper part of the soil collection bucket, and the artificial rotation handle for the soil collection cylinder is used for the up and down movement of the soil collection bucket inside the fixed cylinder.

[0006] The sampling movable drill bit is a structure that can be opened and closed, including a fixed cutting tool head. The fixed cutting tool head is fixedly connected to the inner wall of the bottom of the soil collection bucket. An activity rotating shaft is arranged in the middle of the fixed cutting tool head, and an opening and closing movable blade is rotatably connected to the outside of the activity rotating shaft.

[0007] An artificial rotation handle for the fixed cylinder is arranged on the side surface at the top of the fixed cylinder.

[0008] Spiral blades are arranged on the outer surface of the fixed cylinder.

[0009] A method for using a soil sample collection device for mobile sand dunes. Using the above-mentioned soil sample collection device for mobile sand dunes, it includes the following steps: S1: At the sand dune where sampling is to be carried out, according to the set sampling points, rotate the fixed cylinder. Manually rotate the handle, and through the spiral blade, rotate the fixed cylinder to the set soil sampling depth; S2: Insert the soil sampling cylinder into the fixed cylinder. Rotate the soil sampling cylinder. Manually rotate the handle, and through the fixed cutting tool head, cut the soil and push the opening and closing movable blade to open. The sampling movable drill bit is in an open state, and the soil can enter the soil sampling cylinder; S3: Through the handle of the soil sampling bucket, rotate the soil sampling cylinder to the predetermined soil sampling depth, lift the soil sampling cylinder. Under the action of gravity, the soil compresses the opening and closing movable blade, and the sampling movable drill bit is in a closed state. Lift out the soil sampling cylinder, and take out the target soil sample remaining inside the soil sampling cylinder from the soil sampling pit. After sampling, rotate the fixed cylinder in the reverse direction. Manually rotate the handle and gradually lift the fixed cylinder. Finally, manually fill the drill hole and compact it to complete the sampling.

[0010] The technical effects of the present invention are as follows: 1. Through the fixed cylinder and the soil sampling cylinder, the present invention can continuously and uninterruptedly realize the processes of forming a soil sampling pit, sampling, etc., shorten the construction time, and only one person is required to operate, which can effectively reduce the labor force; 2. By taking soil inside the fixed bucket, the present invention can not only accurately control the soil sampling depth, but also effectively solve the problem of hole collapse often encountered in traditional sampling in mobile sand dunes, and minimize the disturbance to the original sand layer structure to the greatest extent while improving work efficiency.
