Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology, and in particular to an equipment for quickly assisting in the installation of a soil sampler. Background Technology

[0002] Soil moisture measurement is a practical necessity in many fields, including agricultural production, hydrological monitoring, and geotechnical engineering. With the localization of TDR (Time Domain Reflectometry) soil moisture measurement technology, it has become possible to quickly and accurately determine soil volumetric water content without the need for formula calibration. Under this premise, combined with on-site ring sample weighing, soil moisture instruments using TDR technology can quickly measure soil mass water content. The basic principle of TDR technology is to allow high-frequency electromagnetic waves to propagate in the soil. When the high-frequency electromagnetic waves encounter a change in the medium (such as the interface between the soil surface and water), part of the signal is reflected, while the remaining part continues to propagate along the probe. There is a time difference between the time point when the reflected signal is received and the time point when the signal reaches the reflection position. This time difference can be used to calculate the dielectric constant of the measured soil, and then the soil water content can be inferred based on the empirical relationship between the dielectric constant and water content.

[0003] For example, Chinese invention patent application CN117405437A discloses a soil sampler suitable for TDR technology. It changes the original three-needle probe to a single-needle probe and combines it with a sampling tube of appropriate height and volume to create a new sampler. This allows the ring cutter to be used to collect soil at the same time as the central needle is inserted, reducing the waste of manpower on site. At the same time, it avoids secondary damage to the soil and systematic errors caused by the inconsistency between the central needle detection position and the soil sample collection (ring cutter) position.

[0004] However, when implementing TDR technology, the operator needs to insert the probe that propagates electromagnetic waves vertically into the soil. During the manual fixation process, problems such as instability in the soil sampler's position may occur, and the central needle may deviate from its central position. Any deviation in the path will affect the waveform and transmission time of the incident and reflected electromagnetic waves on the sampler. If the central needle deviates, the contact surface between the sampler and the soil will change, causing the incident and reflected paths of the electromagnetic waves propagating in the soil to become unstable. This, in turn, affects the calculation of the crucial "time difference of measurement" parameter, thus impacting the accuracy of the soil moisture measurement results. The device disclosed in CN117405437A lacks a "position stabilization" function and cannot guarantee that the central needle will be inserted into the soil in the correct direction and in a stable manner each time soil is sampled.

[0005] Furthermore, each layer of soil in the field may be of one type or a mixture of multiple soil types, and the dry density of each layer of soil is different. As a result, the soil sampler cannot fully meet the requirements of uniform force and uniform speed during the burial process.

[0006] Therefore, there is a particular need for a device that can quickly assist in the installation of soil samplers to overcome the aforementioned problems in field operations. Utility Model Content

[0007] The purpose of this invention is to provide a soil sampler auxiliary device with a position stabilization function to solve the problems existing in the prior art, ensure that the direction and position of the central needle of the sampler body are stable each time it is inserted into the soil, and design a uniform force structure to adapt to different soil types and dry densities, thereby improving sampling efficiency and measurement accuracy.

[0008] To achieve the above objectives, this utility model provides the following solution:

[0017] The configuration is further defined as follows: the limiting balance assembly includes a balance bar, the first end of which is fixed to the stabilizing plate; the second movable component is a sliding sleeve, which is sleeved on the balance bar; and a cap is provided at the other end of the balance bar.

[0018] The design further includes the following: the lead screw and the balance bar have the same diameter and height; the threaded sleeve and the sliding sleeve have the same diameter and height; and the lead screw and the threaded sleeve are symmetrically arranged on both sides of the collector body.

[0019] The present invention achieves the following beneficial effects compared to the prior art:

[0020] In this invention, the first movable end of the mounting plate is mounted on the auxiliary propulsion assembly via a first movable component. Therefore, the auxiliary propulsion assembly can drive the mounting plate to move. The sampler body, fixed to the mounting plate, can move together with it. This eliminates the need to directly hold the sampler body to insert the central needle into the soil, overcoming the problem of inaccurate needle insertion caused by unstable hand grip.

Due to the relatively simple structural design and the clear connection and fixing methods between the various components, it is convenient for users to carry out daily maintenance and repair.

[0023] 2. Double Fixation: To prevent the collector body from falling off during transportation or use, this utility model uses a screw to fix the iron ring under normal conditions, and then uses an electromagnetic ring for magnetic fixation, providing double protection to ensure the stability of the collector body during use.

[0035] It should also be noted that in the embodiments of this application, the same reference numerals are used to denote the same component or the same part.

[0036] The purpose of this invention is to provide a soil sampler auxiliary device with a position stabilization function to solve the problems existing in the prior art, ensure that the direction and position of the central needle of the sampler body are stable each time it is inserted into the soil, and design a uniform force structure to adapt to different soil types and dry densities, thereby improving sampling efficiency and measurement accuracy.

[0037] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] refer to Figures 1-5This utility model provides a device for quickly assisted in the installation of a soil sampler, including a sampler body 1, an auxiliary propulsion component 2, a mounting plate 9, and a stabilizing plate 18. The sampler body 1 is mounted on the mounting plate 9 via a fixing component. The first movable end of the mounting plate 9 is mounted on the auxiliary propulsion component 2 via a first movable member. The first end of the auxiliary propulsion component 2 is fixedly mounted on the stabilizing plate 18. The sampler body 1 and the auxiliary propulsion component 2 are arranged in parallel and perpendicular to the mounting plate 9 and the auxiliary propulsion component 2 is perpendicular to the stabilizing plate 18. A clearance hole 19 is provided on the stabilizing plate 18 for the sampler body 1 to pass through, and the insertion end of the stabilizing plate 18 is directly opposite the clearance hole 19.

[0039] Working principle:

[0040] In this invention, the first movable end of the mounting plate 9 is mounted on the auxiliary propulsion assembly 2 via a first movable component. Therefore, the auxiliary propulsion assembly 2 can drive the mounting plate 9 to move. The collector body 1, fixed on the mounting plate 9, can move together with the mounting plate 9. Thus, by controlling the auxiliary propulsion assembly 2, the collector body 1 can be driven to move without contacting it. The central needle can be inserted into the soil without directly holding the collector body 1, overcoming the problem of inaccurate insertion of the central needle caused by the inability of the human hand to hold the collector body 1 stably. The stabilizing plate 18 abuts against the ground, which can level the soil in the target area and improve the overall stability of the soil sampler auxiliary device. The clearance hole 19 can eliminate the interference between the collector body 1 and the stabilizing plate 18, ensuring that the collector body 1 can be smoothly inserted into the soil.

[0041] Furthermore, the fixing assembly includes a screw 16 with a throttle 17, a fixing hole 10 on the mounting plate 9, an iron ring 12 on the top of the collector body 1, the iron ring 12 being inserted into the fixing hole 10, a first threaded hole 1301 on the side of the iron ring 12, and a second threaded hole 1302 corresponding to the first threaded hole 1301 on the side of the fixing hole 10. The screw 16 sequentially fixes the second threaded hole 1302 and the first threaded hole 1301. The screw 16 locks the iron ring 12 and the mounting plate 9 together, completing the installation of the collector body 1. The throttle 17 improves operational convenience; preferably, the throttle 17 is a swivel throttle.

[0042] Furthermore, the fixing assembly also includes a matching iron ring 12 and an electromagnetic ring 11 matching the iron ring 12. The electromagnetic ring 11 is disposed within the fixing hole 10, and a positioning groove 14 is formed on the electromagnetic ring 11. A positioning post 15 matching the positioning groove 14 is provided on the iron ring 12, and the positioning post 15 is inserted into the positioning groove 14. The positioning groove 14 and the positioning post 15 cooperate to increase the attraction area and effectively resist the radial force on the iron ring 12, stabilizing the collector body 1. During detection, the electromagnetic ring 11 is de-energized to eliminate the influence of the magnetic field.

[0043] Furthermore, the projections of the iron ring 12 and the electromagnetic ring 11 in the vertical direction coincide. After attraction, the iron ring 12 and the electromagnetic ring 11 completely overlap, and there will be no situation where one end has a larger area and the other end has a smaller area, and there is no usable moving area, ensuring the stable position of the iron ring 12 and the electromagnetic ring 11.

[0044] Furthermore, the electromagnetic ring 11 is equipped with a switch and a built-in rechargeable battery.

[0045] Furthermore, the auxiliary propulsion component 2 includes a lead screw 4, the first end of which is connected to the stabilizing plate 18 via a rotating shaft. The first movable component is a threaded sleeve 6, which is fitted onto the lead screw 4. The first end of the lead screw 4 is provided with a rotating shaft. When the lead screw 4 rotates, it does not move itself, but the threaded sleeve 6 moves, driving the mounting plate 9 to move, thereby realizing the movement of the collector body 1.

[0046] Furthermore, a rotary knob 5 is provided at the second end of the lead screw 4, and the circumferential surface of the rotary knob 5 is provided with anti-slip texture.

[0047] Furthermore, it also includes a limiting and balancing component 3, which is set parallel to the collector body 1. The limiting and balancing component 3 and the auxiliary propulsion component 2 are located on opposite sides of the collector body 1. The second movable end of the mounting plate 9 is mounted on the limiting and balancing component 3 via a second movable component. The balancing component 3 is fixed to the stabilizing plate 18. The function of the balancing component 3 is to adjust the overall center of gravity of the soil sampler auxiliary device. When the soil sampler auxiliary device is placed on the ground, there will be no obvious offset that requires manual adjustment. The collector body 1 can be inserted into the soil simply by operating the auxiliary propulsion component 2.

[0048] Furthermore, the limiting and balancing assembly 3 includes a balance rod 7, the first end of which is fixed to the stabilizing plate 18, and a second movable component, a sliding sleeve 8, which is fitted onto the balance rod 7. A cap is provided at the other end of the balance rod 7. The combined structure of the balance rod 7 and the sliding sleeve 8 ensures the smooth movement of the mounting plate 9, and while providing a balancing function, it does not affect the movement of the collector body 1.

[0049] Furthermore, the lead screw 4 and the balance bar 7 have the same diameter and height, and the threaded sleeve 6 and the sliding sleeve 8 have the same diameter and height. The lead screw 4 and the threaded sleeve 6 are symmetrically arranged on both sides of the collector body 1. The symmetrical arrangement of the lead screw 4 and the balance bar 7 ensures that the center of gravity of the device is close to the geometric center, thus achieving a good balance effect.
