Since motor soil drills require external power supply, it is not convenient to carry out sampling work in the sample plot. The drill bit and the drill body of the manual soil drill are connected in a single way, and the sampling pedal is often a ring sleeve on the drill rod, which is easy to slip when the foot exerts force to sample. In addition, when sampling soil, it is difficult to exert force with one foot, and the soil collection process is troublesome and laborious, and the work efficiency is low. The soil taken by the drill bit is not easy to fall off, and it is necessary to knock hard on the drill bit or use a scraper to slowly take out the soil sample. Utility Model Content

[0024] The technical solution of the utility model is described in detail below with reference to the accompanying drawings, but the protection scope of the utility model is not limited to the embodiments.

[0025] In order to make the purpose and implementation of the present application clearer, the exemplary implementation of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all of the embodiments. It should be noted that the brief description of the terms in this application is only for the convenience of understanding the implementation described below, and is not intended to limit the implementation of the present application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

It should be understood that the terms used in this way are interchangeable under appropriate circumstances. The terms "including" and "having" and any variations thereof are intended to cover but not exclude inclusion. For example, a product or device comprising a series of components is not necessarily limited to all the components clearly listed, but may include other components not clearly listed or inherent to these products or devices.

[0027] A soil drilling device, such as Figure 1 As shown, it includes a foot pedal assembly, a hand-held assembly, a drill bit assembly and a soil extraction assembly. The foot pedal assembly is for stepping on with both feet, the hand-held assembly is fixed on the upper side of the foot pedal assembly for holding with both hands, the drill bit assembly is fixed on the lower side of the foot pedal assembly and can drill into the soil, and the soil extraction assembly is axially movably arranged in the drill bit assembly to push the soil in the drill bit assembly to facilitate soil extraction and sampling.

[0028] When drilling, the operator can hold the handheld assembly with both hands, stand on the pedal assembly with both feet, and use their own gravity to twist left and right to exert force to make the drill assembly extend into the soil, and pull it out when it reaches a certain depth. Then, the soil collected inside the drill assembly can be pushed out by the displacement of the soil extraction assembly.

[0029] In some embodiments, the pedal assembly is configured as a pedal 4, the area of ​​which is larger than the contact surface of the feet, and is sufficient for the operator's feet to stand and step on, making soil extraction more labor-saving. Exemplarily, the shape of the pedal 4 can be a rectangle for feet to step on.

[0030] Specifically, the handheld assembly includes a support rod 2 and a handle 1. The support rod 2 can be two solid steel columns, which are longitudinally connected to the pedal 4, and the handle 1 is fixed to the top of the support rod 2. The two support rods 2 are fixed to the pedal 4 symmetrically to ensure the stability of the handheld.

[0031] In order to reduce the friction of the operator's hands, the handle 1 is coated with a wear-resistant layer 101 to avoid excessive force during operation and causing scratches on the hands.

[0032] The drill assembly and the support rod 2 are welded together through the pedal 4. Specifically, the drill assembly includes a hollow drill rod 7, the end of which is configured as a blade with an inclined arc, and the inclination angle formed by the plane where the blade is located can be determined according to the soil to be drilled, and the preferred inclination angle is 45°.

[0033] Specifically, the soil sampling assembly includes a connecting rod 5, a foot pedal 3 and a bulldozer 6; the connecting rod 5 passes through the pedal 4 through a reserved hole 8 and axially penetrates the drill assembly; the foot pedal 3 is fixed to the upper end of the connecting rod 5, and the bulldozer 6 is fixed to the lower end of the connecting rod 5, and the bulldozer 6 is adapted to the inner diameter of the drill assembly. After the soil sample is collected, the handle 1 can be held and the foot pedal 3 can be stepped on with one foot to exert force, so that the bulldozer 6 can move axially and press down in the hollow drill rod 7, pushing the compacted soil in the hollow drill rod 7 during the drilling process to fall, which is convenient for taking out the sampled soil.

[0034] The pedal assembly is provided with a reserved hole for the connecting rod 5 to pass through. The diameter of the reserved hole is adapted to the outer diameter of the connecting rod 5, and the inner wall of the reserved hole is as smooth as possible to reduce the contact friction between the connecting rod 5 and the reserved hole.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
