Description

Technical Field

[0001] This invention belongs to the field of soil sampler technology, specifically relating to a soil sampler with a self-vibrating replaceable sampling cylinder. Background Technology

[0002] With the development of ecological research, the distribution and migration of elements and microorganisms in soil and their impact on groundwater pollution are becoming increasingly in-depth. Research on the nutrient and element distribution at different soil depths is also growing. Soil samplers are necessary in soil research, but current soil samplers on the market still have the following problems:

[0003] In existing soil samplers, the sampling tube is often fixed together with other components. After prolonged use, contaminants and impurities adhere to the tube wall. When collecting soil samples, the soil comes into direct contact with these impurities on the tube, which can easily affect the soil analysis data and lead to inaccurate sampling results.

[0004] Moreover, after repeated use, the existing soil sampler suffers severe wear on the drill bit edge, resulting in reduced sampling efficiency. When faced with soils with unique terrain and complex plant root systems, the resistance during soil sampling is significant, requiring a great deal of physical exertion from the user.

[0005] Based on this, a soil sampler with a self-vibrating replaceable sampling tube is proposed. Summary of the Invention

[0011] The bottom end of the annular boss is provided with a spherical groove, which is used to install the steel ball. The inner bottom surface of the gear disk is provided with multiple wedge-shaped bosses at equal intervals in a circumferential direction, which are used in conjunction with the steel ball.

[0012] A magnetic base is mounted on the outer side of the gear disk via a thrust bearing, and the sampling cylinder is installed inside the magnetic base.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figure 1-4 As shown, the present invention provides a technical solution: a soil sampler with a self-vibrating replaceable sampling tube, including a sampling tube 1, a magnetic base 2, a gear disk 4, a hand-held flange 6, and a detection and positioning shaft 7;

[0031] One end of the detection positioning shaft 7 is set as a pointed tip, and a detection device is set at the pointed tip of the detection positioning shaft 7. A central hole for passing through the data cable is opened on the axis of the detection positioning shaft 7. The diameter of the central hole is 2-3mm. The flat end of the detection positioning shaft 7 can be connected to an external detection data processing and display device.

[0032] The outer side of the detection positioning shaft 7 is also provided with a stepped groove with scale. The connecting plate 61 of the handheld flange 6 has a connecting hole 63 in the middle. The connecting hole 63 is provided with a locking mechanism for locking and connecting with the stepped groove. The fixed connection between the handheld flange 6 and the detection positioning shaft 7 is completed by the locking mechanism in the connecting hole.

[0033] The connecting plate 61 of the hand-held flange 6 is also vertically mounted with hand-held rods 62 on both sides, and external vertical force is applied through the hand-held rods 61.

[0034] The bottom outer periphery of the handheld flange 6 is also provided with an annular boss 64. Multiple electromagnet plates 65 are installed at equal intervals on the inner and outer sides of the annular boss 64. The handheld flange 6 has a built-in circuit module, which is used to switch the N and S poles of the electromagnet plates 65.

[0035] The gear disk 4 is provided with a positioning boss 41, and the outer side of the gear disk 4 is also provided with an annular groove 42. The positioning boss 41 is provided with a middle hole for detecting the transmission of the positioning shaft 7.

[0036] Multiple permanent magnets 43 are equally spaced on the outer side of the positioning boss 41, and multiple permanent magnets 43 are also equally spaced on the inner side of the annular groove 42. The permanent magnets 43 on the outer side of the positioning boss 41 and the permanent magnets 43 on the inner side of the annular groove 42 are arranged in a circumferential manner with alternating N and S poles. The electromagnet plate 65 is used in conjunction with the permanent magnets 43.

[0037] The outer side of the gear disk 4 is also provided with a gear groove 45, through which the gear groove 45 completes the meshing connection with the external power source.

[0038] The bottom end of the annular boss 64 is provided with a spherical groove 66, which is used to install the steel ball 3. After the steel ball 3 is installed in the spherical groove 66, it can rotate freely and will not fall out of the spherical groove 66.

[0039] The inner bottom surface of the gear disk 4 is provided with a plurality of wedge-shaped protrusions 44 at equal intervals in a circumferential direction. The height of the wedge-shaped protrusions 44 is 0.5-0.8 times the diameter of the steel ball 3. The wedge-shaped protrusions 44 are used in conjunction with the steel ball 3.

[0040] A magnetic base 2 is mounted on the outer side of the gear disk 4 via a thrust bearing 5. The sampling cylinder 1 is installed inside the magnetic base 2. Specifically, a magnetic layer is provided on the top surface of the sampling cylinder 1. The magnetic layer is used in magnetic cooperation with the magnetic base 2. A cutting edge is provided on the lower edge of the sampling cylinder 1. The sampling cylinder 1 is used to quickly enter the soil through the cutting edge.

[0041] In practical use, the operator applies a certain vertical force to the gear disk 4 through the handle 62 of the hand-held flange 6, and at the same time connects the built-in circuit module of the hand-held flange 6. The circuit module controls the electromagnet plate 65 to periodically switch between the N pole and the S pole, so that the electromagnet plate 65 is arranged with the N pole and S pole alternately along the circumference. At the same time, it is set to the same pole repulsion mode with the permanent magnet 43 on the outside of the positioning boss 41 and the permanent magnet 43 on the inside of the groove 42. Under the magnetic push, the hand-held flange 6 is regarded as the stator and the gear disk 4 is regarded as the rotor. The gear disk 4 is driven by the magnetic force to rotate along the detection positioning shaft 7. The wedge-shaped boss 44 on the gear disk 4 rotates synchronously along the detection positioning shaft 7. The wedge-shaped boss 44 cooperates with the steel ball 3 in the rotation path, so that the vertical force applied by the steel ball 3 to the gear disk 4 is a pulsed periodic change. Finally, the pulsed vertical force is applied to the sampling cylinder 1, so that the sampling cylinder 1 can penetrate the soil more quickly. The device can be connected to an external power source and meshes with the gear groove on the outer wall of the gear disk 4 to further enhance vibration performance. After reaching a specified depth, it reads the sensor data at this location and accurately records relevant index data. Subsequently, the product is pulled out of the soil by lifting it up through the hand flange 6. Then, the sampling cylinder 1 filled with soil sample is removed, and a new sampling cylinder 1 is replaced to prepare for a new sampling operation, which is convenient and practical.
