Description

Technical Field

[0001] The utility model belongs to the technical field of soil sampling and relates to a soil sampling device. Background Art

[0002] With the development of society and scientific progress, in many fields such as agricultural production, soil remediation, geological exploration, etc., it is necessary to inspect and test the soil environment in the target area to understand the soil structure, composition, etc., so soil sampling is necessary.

[0003] Patent document CN220670980U discloses a soil sampling device for agricultural testing technology. This device, which belongs to the field of agricultural testing technology, includes a fixed frame with an electric telescopic rod mounted on one side of the top of the fixed frame. The telescopic end of the electric telescopic rod is mounted on a placement plate, the top of the placement plate is mounted on a mounting plate, and the top of the mounting plate is mounted on a motor. This soil sampling device for agricultural testing technology benefits from the design of the electric telescopic rod, motor, placement plate, and sampling tube. After moving the sampling device to a designated location, the motor is turned on and the electric telescopic rod is turned off. The motor drives the sampling tube to rotate, and the electric telescopic rod is closed. Its telescopic end resets, driving the placement plate downward, which in turn drives the sampling tube downward for sampling.

[0004] However, the above prior art still has the following deficiencies:

[0005] The above-mentioned prior art uses a sampling tube to sample the soil. Since the sampling tube is an integrated structure and the sampling tube and the rotating shaft at the output end of the motor are fixed to each other and cannot be disassembled, it is inconvenient to remove the soil sample in the sampling tube, and the inside of the sampling tube cannot be cleaned. After the sampling tube is used too many times, a lot of soil will adhere to its inside, thereby affecting the next sampling standard. Utility Model Content

[0006] The purpose of the utility model is to address the deficiencies of the existing technology and propose a soil sampling device for solving the technical problems of the existing technology mentioned in the background technology, such as the inconvenience of removing soil from the sampling tube and the inconvenience of cleaning the inside of the sampling tube.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A soil sampling device comprising:

[0009] Support frame;

[0010] A mounting plate, the mounting plate being vertically slidably mounted on the support frame;

[0011] A motor is fixed on the top of the mounting plate;

[0012] A mounting plate, one end of which is fixed to one end of the motor output shaft passing through the mounting plate;

[0013] Two semi-cylindrical sampling sleeves are detachably mounted on both ends of the mounting plate and are symmetrically arranged. One end of the two sampling sleeves is pressed against each other and combined into a sampling cylinder. A cleaning scraper (7) is provided inside the two sampling sleeves (5);

[0014] The cylinder is fixed on the top of the mounting plate, and the telescopic end of the cylinder passes through the mounting plate and is fixed with a cleaning scraper located in the sampling barrel, and the outer wall of the cleaning scraper is in contact with the inner walls of the two sampling sleeves.

[0015] Working principle:

[0016] The mounting plate is driven to rotate by a driving motor, and the mounting plate drives the two sampling sleeves installed thereon to rotate synchronously, pressing down the mounting plate, and the mounting plate moves down along the support frame and drives the motor to move down. The motor drives the two sampling sleeves to move down synchronously through the mounting plate, thereby realizing soil sampling and processing of farmland. The driving cylinder drives the cleaning scraper to move downward, and the cleaning scraper pushes the soil in the sampling cylinder out. At the same time, the cleaning scraper can scrape and clean the soil adhered to the inner walls of the two sampling sleeves.

[0017] The beneficial effects of the utility model are:

[0018] The utility model is provided with a cylinder and a scraper, and the cleaning scraper is driven downward by the cylinder, and the cleaning scraper pushes the soil in the sampling tube out without manual labor, and it is convenient to take out the soil sample, thereby improving the sampling efficiency. At the same time, the cleaning scraper can scrape and clean the soil adhered to the inner walls of the two sampling sleeves to avoid affecting the standard of the next sampling. The utility model is provided with a mounting plate and two sampling sleeves detachably mounted on the mounting plate, which is convenient for disassembling the two sampling sleeves, and further facilitates the cleaning and processing of the sampling sleeves.
