Description

TECHNICAL FIELD

[0001] The utility model relates to geological exploration equipment technical field, concretely is a combined soil surface knife. BACKGROUND

[0002] In soil sampling, investigation and exploration activities, accurately obtaining the surface structure and surface characteristics of soil samples is very critical. Especially in the process of geological exploration, soil surface sampling is of great significance for subsequent analysis, detection and research. Surface sampling can preserve the original microstructure and physical properties of soil, reflecting the situation of soil in natural state, so it has wide application in soil composition analysis, soil quality assessment and environmental monitoring fields.

[0003] The traditional soil surface sampling method generally relies on manual operation, using some common tools such as shovel, hammer, chisel, etc. These tools can complete soil sampling work, but due to the design not specifically for the needs of surface sampling, there are many limitations. First of all, the design of ordinary tools does not effectively consider the accuracy and efficiency of soil surface sampling, so that the operator needs to have high skill level to complete the standard surface sampling. Secondly, during the operation process, the working surface of the ordinary tool cannot uniformly cut the soil, causing the soil surface to be irregular, affecting the authenticity of the surface structure. This irregular surface sampling not only increases the error of subsequent analysis, but also reduces the repeatability and reliability of sampling.

[0004] In addition, the traditional manual operation method often needs to adjust the tool repeatedly, change the operation angle or apply different force during the sampling process, which makes the efficiency of soil surface sampling low, and a lot of time and physical effort are needed. In some time-constrained or heavy soil exploration tasks, the traditional soil surface sampling tool often cannot meet the actual needs, resulting in low overall exploration efficiency and difficulty in ensuring high precision of sampling.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example

[0022] This application introduces a combined soil roughening cutter, comprising: a U-shaped frame 1, a rolling cutter module 3, and a handle 2; a plurality of rolling cutter modules 3 are rotatably mounted on the opening of the U-shaped frame 1, and a handle 2 is mounted on the back of the opening of the U-shaped frame 1 via a rotating shaft 4 to facilitate pushing the rolling cutter modules 3 relative to the U-shaped frame 1 to achieve roughening of the soil profile.

[0023] The rolling cutter module 3 includes a cone 35, a cutter 36, serrations 37, and a wire brush 38. The rolling cutter module 3 is a cylindrical disc with a central rotating hole 33, which rotatably engages with a rotating shaft 4. The cone 35, cutter 36, serrations 37, and wire brush 38 are evenly distributed around the circumference of the rolling cutter module 3. The cone 35, cutter 36, serrations 37, and wire brush 38 represent different shaped soil breaking profiles, enriching the treatment options for rough soil surfaces.

[0024] In one embodiment, the rolling cutter module 3 has a protrusion 31 with a non-rotating shape on one side of its axial surface, and a concave portion 32 that fits into the protrusion 31 on the other side. When adjacent rolling cutter modules 3 use the same protrusion 31 or concave portion 32 to fit together, two adjacent rolling cutter modules 3 can roll relative to each other. Different cones 35, cutters 36, serrations 37 and wire brushes 38 will roll randomly relative to each other, which is suitable for soft soil. When adjacent rolling cutter modules 3 use the protrusion 31 and concave portion 32 to fit together, the protrusion 31 is embedded in the concave portion 32 to restrict relative rotation, and can only roll synchronously.

[0025] In one embodiment, the axial surface of the rolling blade module 3 is provided with four locking holes 34 penetrating the thickness direction of the rolling blade module 3. The positions of the four locking holes 34 correspond to the cone 35, the cutter 36, the saw teeth 37 and the wire brush 38. The U-shaped frame 1 is provided with stop holes 6 corresponding to the locking holes 34. By inserting a shaft-like part through the stop hole 6 into the locking holes 34 of all the rolling blade modules 3 in series, all the rolling blade modules 3 can be locked on the U-shaped frame 1, turning into a scraper instead of a rolling blade, thus enriching the methods for treating rough soil surfaces.

[0026] In one embodiment, the handle 2 is threadedly connected to the U-shaped frame 1. The back of the opening of the U-shaped frame 1 is provided with several storage slots 7 for fitting into the circumferential surface of the handle 2. When the handle 2 is located in the storage slot 7, its axis is parallel to the back of the opening of the U-shaped frame 1. After the handle 2 is removed from the U-shaped frame 1, it is pressed into the storage slot 7, which can quickly store the knife, reduce space occupation, and improve portability.

[0027] In one embodiment, the handle 2 has a hollow blind hole structure and is equipped with a stop pin 5 for engaging the locking hole 34 and the stop hole 6. This facilitates the storage of the stop pin 5 and provides structural protection to prevent deformation of the stop pin 5. The end of the stop pin 5 is provided with a pin cover 5 with a diameter larger than that of the handle 2, which allows the stop pin 5 to be easily pulled out of the handle 2.

[0028] In one embodiment, the bottom of the hollow blind hole structure of the handle 2 is provided with a magnetic block 21 that magnetically attracts the stop pin 5, further facilitating the storage of the stop pin 5.

[0029] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
