[0002] In the field of soil science research and geological exploration, one of the basic tasks is the collection of soil samples. The collection of soil samples provides a material basis for the determination of the physical and chemical properties of the soil in the area. Changes in moisture, nutrient composition and content in agricultural soils have an important impact on crop yields. Therefore, during the collection of soil samples, it is important not to destroy the original properties of the soil, such as its original composition, morphology, and layers, which is of great significance to the accurate determination of soil properties.
[0003] In the prior art, soil collection devices for soil testing are mainly soil drill sampling. The drill body enters the soil layer to a certain depth, and the soil in the section where the drill body is located enters the drill bit in turn. Then the drill body is lifted up, and the soil in the section from the surface to the depth reached by the drill bit is brought above the ground with the drill body, and then cut and sampled as needed. However, in the prior art, when the drill body enters the soil, the shallow soil on the surface is easily adhered to the drill bit, which is difficult to clean and distinguish during sampling, and the soil at a specific depth cannot be accurately obtained, affecting the detection results.

The soil collecting device for soil detection provided by the utility model, after the sleeve 1 is drilled downward to a specific depth, the operating rod 2 is moved downward, and the first limit member 101 and the second limit member 102 are separated from each other under the downward force of the drill bit 3, so that the bottom end of the sleeve 1 is in an open state, so that the drill bit 3 can pass through the bottom end of the sleeve 1 to drill the soil of the required depth ( Figure 2 The upper soil layer is avoided, which solves the problem that deep soil sampling is easily contaminated by shallow soil.
[0027] like Figure 1 and Figure 2 As shown, as a preferred embodiment of the utility model, the drill bit 3 is a spiral tube structure. The design of this structure makes it easier for the drill bit 3 to be inserted into the soil, thereby improving the working efficiency.
[0028] Figure 3 A schematic diagram of the structure of an articulated assembly in a soil collection device for soil detection provided by an embodiment of the utility model is shown in FIG. Figure 3 As shown, as a preferred embodiment of the present utility model, the first limit member 101 is connected to the bottom end of the sleeve 1 through the first hinge assembly 4, and the second limit member 102 is connected to the bottom end of the sleeve 1 through the second hinge assembly.
[0029] like Figure 3As shown, as a preferred embodiment of the utility model, the first hinge assembly 4 includes a first rotating member 401, which is arranged on the first stopper 101 and close to the outer side of the bottom end of the sleeve 1, and a first rotating shaft 402 is fixedly arranged on the first rotating member 401; a first fixing member 403 is arranged on the sleeve 1, and a first rotating groove 404 with a structure adapted to the first rotating shaft 402 is opened on the first fixing member 403, and the first rotating shaft 402 can be rotatably inserted in the first rotating groove 404. The second hinge assembly includes a second rotating member, which is arranged on the second stopper 101 and close to the outer side of the bottom end of the sleeve 1, and a second rotating shaft is fixedly arranged on the second rotating member; a second fixing member is arranged on the sleeve 1, and a second rotating groove with a structure adapted to the second rotating shaft is opened on the second fixing member, and the second rotating shaft can be rotatably inserted in the second rotating groove.

In the application provided in this embodiment, the rotating shaft 402 can be rotatably inserted into the rotating groove 404 .
[0030] Figure 4 A schematic diagram of the structure of elastic members and their connection relationships in a soil collection device for soil detection provided by an embodiment of the utility model is shown as follows: Figure 4 As shown, as a preferred embodiment of the utility model, a first fixing block 501 is provided on the inner side of the first limiting member 101 and the second limiting member 102 near one end of the sleeve, an elastic member 5 is provided on the first fixing block 501, the end of the elastic member 5 is connected to the second fixing block 502, and the second fixing block 502 is provided on the inner side of the sleeve 1. The design of the first fixing block 501 and the second fixing block 502 enables the elastic member 5 to be vertically connected between the first limiting member 101 or the second limiting member 102 and the lower end of the sleeve 1 to prevent the elastic member 5 from being bent non-axially and causing the elastic member 5 to approach the drill bit 3, thereby affecting the movement of the drill bit 3.

The design of this structure can prevent the operating rod 2 from falling into the sleeve 1, and also makes it more convenient to move the operating rod 2 up and down, and the soil extraction efficiency is higher.
[0033] like Figure 1 and Figure 2 As shown, as a preferred embodiment of the present utility model, a sleeve handle 103 is provided at the upper end of the sleeve 1. The design of this structure makes it more convenient to move the sleeve 1 up and down, and the soil taking efficiency is higher.
[0034] like Figure 2 As shown in FIG. 1 , as a preferred embodiment of the present invention, a spiral leaf 104 is arranged on the outer side of the sleeve 1. The design of this structure makes it easier for the sleeve 1 to continue to drill downward into the soil, thereby improving the working efficiency.
