Description

Technical Field

[0001] The utility model relates to the field of geological exploration, in particular to a soil coring device. Background Art

[0002] Soil coring is a common operation in geological exploration. It involves extracting soil samples from the ground using specialized equipment for analysis of the soil's properties, structure, and various physical and chemical parameters. In geological engineering, soil coring is extremely important because it provides direct information about subsurface soil conditions, which is crucial for the design of civil engineering structures such as building foundations, roadbeds, and dams.

[0003] After obtaining soil samples using a soil coring device, the soil samples are subjected to laboratory testing to determine the soil's physical properties such as density, porosity, water content, and permeability, analyze the chemical composition of the soil samples, understand the soil's mechanical properties such as shear strength, compressibility, and expansion, evaluate possible pollutants in the soil, and conduct environmental quality analysis.

[0004] In the prior art, for example, Chinese Patent No. 202220958925.7 discloses a soil sampling device for small watershed environmental monitoring. The device includes a body, a handle, a connecting shaft, and a coring drill bit, making soil sampling more labor-saving. However, the above device has the following shortcomings: when the coring drill bit is moved up and down, the device rotates the corresponding transmission structure through the handle, making it relatively cumbersome for workers to operate. At the same time, the device uses a single positioning rod inserted into the soil, which makes the overall stability of the device insufficient during use.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

DETAILED DESCRIPTION

[0023] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. By referring to these contents, ordinary technicians in this field should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0024] According to an embodiment of the present utility model, a soil coring device is provided.

[0025] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. Figure 1-4As shown, a soil coring device according to an embodiment of the present invention comprises a support 1, with several ground spikes 2 mounted at its bottom end. A lifting mechanism 3 is located within the support 1. One end of the lifting mechanism 3 extends to the side of the support 1 and houses a first motor 4. A soil coring drill bit 5 is located at the bottom end of the first motor 4. The soil coring drill bit 5 is hollow and has a scale on it, allowing the operator to determine the depth of penetration into the soil by observing the scale. A quick-release mechanism 6 is located between the first motor 4 and the soil coring drill bit 5. When the soil coring drill bit 5 is in use, it is lowered by the lifting mechanism 3 and gradually penetrates the soil as it rotates. When the coring drill bit reaches a predetermined depth, the lifting mechanism 3 lifts the soil coring drill bit 5 and the soil sample out of the soil surface. The sample is then placed in a sealed container and labeled with relevant information (such as sampling location, depth, and time) for subsequent soil analysis and testing.

[0026] With the help of the above scheme, the utility model can complete the soil sample collection for geological engineering, and can automatically complete the soil sample collection, which makes the operation simpler and more labor-saving. At the same time, the coordinated use of multiple ground nails 2 and brackets 1 increases the stability of the device in the soil, thereby improving the overall stability of the device.

[0027] In one embodiment, the lifting mechanism 3 includes a screw 301 vertically disposed within the bracket 1, a guide rod 302 disposed on the side of the screw 301, and a lifting plate 303 sleeved on the outside of the screw 301, the lifting plate 303 slidingly engaging with the guide rod 302, and one end of the lifting plate 303 extending to the outside of the bracket 1; the lifting mechanism 3 also includes a housing 304 disposed at the top of the bracket 1, a worm gear 305 connected to the inside of the housing 304 and located at the top of the screw 301; a worm 306 meshing with the side of the worm gear 305, and a second motor 307 disposed at one end of the worm gear 306, thereby simplifying the tedious process of manual rotation and enabling faster adjustment of the height of the soil coring drill bit 5, thereby improving work efficiency and operational convenience. At the same time, when in use, the first motor 4 and the second motor 307 are connected to an external power supply and a control panel, and the control panel includes a PLC to control the first motor 4 and the second motor 307.

[0028] The working principle of the lifting mechanism 3 is as follows: the second motor 307 drives the worm 306 to rotate, thereby driving the worm wheel 305 to rotate, and then the screw rod 301 to rotate, driving the lifting plate 303 to move up and down, and adjusting the height of the soil coring drill bit 5.

[0029] In one embodiment, for the above-mentioned quick-release mechanism 6, the quick-release mechanism 6 includes a connecting block 601 arranged at the bottom end of the output shaft of the first motor 4, a square hole 602 is provided at the bottom end of the connecting block 601, a square block 603 is provided at the top end of the soil coring drill bit 5 and is located in the square hole 602, and a circular hole 604 is provided in the square block 603; the outer wall of the connecting block 601 is provided with a cylinder 605, and a round rod 606 is provided inside the cylinder 605, one end of the round rod 606 passes through the side wall of the connecting block 601 and extends into the circular hole 604, and the other end of the round rod 606 extends to the cylinder 605; a baffle 607 is provided inside the cylinder 605 and on the outside of the round rod 606, and a spring 608 is provided on the end of the baffle 607 away from the connecting block 601, so that the replacement process of the soil coring drill bit 5 becomes quick and simple, which greatly shortens the adjustment time of the device. At the same time, through the connection between the square hole 602 and the square block 603, the connection provides a larger contact area, thereby providing a larger torque transmission capacity, and the soil coring drill bit 5 can cut the soil more effectively, and due to the more uniform force distribution, this helps to reduce the wear of the soil coring drill bit 5.

[0030] The working principle of the quick-release mechanism 6 is as follows: when the soil coring drill bit 5 needs to be removed, the outer end of the round rod 606 is pulled to withdraw it from the round hole 604, and the soil coring drill bit 5 can be quickly removed. When installing, the operation is reversed.

[0031] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.

[0032] In actual application, the bracket 1 is placed at a predetermined sampling position and secured to the ground by a number of ground spikes 2. The soil coring drill bit 5 is mounted on the output shaft of the first motor 4 using the quick release mechanism 6. The height of the soil coring drill bit 5 is adjusted by the lifting mechanism 3.

[0033] The first motor 4 rotates the coring drill bit 5, which then penetrates the soil, cuts, and collects soil samples. As the coring drill bit 5 rotates, the lifting mechanism 3 controls its vertical movement, ensuring smooth penetration. When the coring drill bit 5 reaches the predetermined depth, the first motor 4 stops rotating. The lifting mechanism 3 then lifts the coring drill bit 5, along with the soil sample, out of the soil.

[0034] In summary, the present invention can complete the soil sample collection for geological engineering, and can automatically complete the soil sample collection, making the operation simpler and more labor-saving. At the same time, the coordinated use of multiple ground nails 2 and brackets 1 increases the stability of the device in the soil, thereby improving the overall stability of the device. By providing a lifting mechanism 3, the tedious process of manual rotation is simplified, and the height of the soil coring drill bit 5 can be adjusted more quickly, thereby improving work efficiency and operational convenience. By providing a quick-release mechanism 6, the replacement process of the soil coring drill bit 5 becomes quick and simple, greatly shortening the adjustment time of the device. At the same time, through the connection method of the square hole 602 and the square block 603, the connection provides a larger contact area, thereby providing a larger torque transmission capacity. The soil coring drill bit 5 can cut the soil more effectively, and due to the more uniform force distribution, this helps to reduce the wear of the soil coring drill bit 5.
