[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] A soil sampling device for roadbed includes a sampling pipe, a linked bulldozing saw device, and an auxiliary unloading device. The linked bulldozing saw device is installed on the sampling pipe. The linked bulldozing saw device includes a steel ring with several steel teeth connected to the bottom side of the steel ring. A screw is connected to each of the upper two sides of the steel ring. A push plate is installed between the two screws. Handles are connected to both sides of the sampling pipe. A strip groove is opened on both sides of the inner wall of the sampling pipe. The two screws can be inserted and engaged with the two strip grooves respectively.

[0006] To further achieve the purpose of this utility model, the following technical solution can also be adopted: a screw hole is opened on the upper part of the steel ring, screw holes are opened on both sides of the push plate, one end of the screw is threadedly connected to the steel ring through the screw hole, and the other end of the screw is threadedly connected to the push plate through the screw hole.

[0007] The upper part of the steel ring is connected to several positioning posts, and the bottom of the soil sampling pipe is provided with several positioning holes. Each positioning post can be inserted into a positioning hole.

[0021] This utility model adds a linkage bulldozing saw tooth device and an auxiliary unloading device. After the soil is removed, the linkage bulldozing saw tooth device allows personnel to conveniently push the push plate 2 out of the soil inside the soil removal tube 1 by stepping on the foot pedal 14 and pulling the handle 3 with their hands, and separate the steel ring 6 from the soil removal tube 1, thus making it easier for personnel to remove the soil inside the soil removal tube 1.

[0022] Specific material selection and feasibility analysis: The samples we actually produced used the accompanying drawings as blueprints, implementing the process according to the proportions and fit of each component shown in the drawings. The connections employed included common methods such as strong adhesive bonding, welding, riveting, flange connections, and one-piece molding. During actual production, the appropriate connection method, thickness, and strength of the connection points can be selected based on the required connection strength without creative design. Figure 1 During the process, personnel can hold both handles 3 with both hands to press down and rotate the soil sampling pipe 1 to sample soil from the roadbed. After sampling, personnel can thread the bolt 12 into the screw hole 10 to achieve... Figure 2 In this state, the personnel step on pedal 14 and pull handle 3 with both hands to gradually separate the soil sampling pipe 1 from the steel ring 6, achieving... Figure 3 In this process, the pusher plate 2 simultaneously pushes out the soil inside the soil extraction pipe 1, achieving... Figure 4 state.

[0023] Example 2:
