Description

Technical Field

[0001] This utility model relates to the field of soil assessment technology, specifically a sampling device for evaluating the suitability of soil for agricultural use. Background Technology

[0002] Soil suitability assessment for agricultural use evaluates the suitability and limitations of soil for specific agricultural uses by analyzing the physical, chemical, and biological properties of the soil, as well as the natural environment and socioeconomic conditions in which the soil is located. Soil sampling is an essential step in the assessment, which requires the use of sampling devices. However, existing sampling devices are often complex and cumbersome to use, or their simple structure makes them laborious and difficult to use for sampling.

[0003] To overcome the aforementioned shortcomings, existing technology (Chinese patent application number: 201810783069.4, application date: July 17, 2018) discloses a soil sampling device for soil testing, including an outer cylinder with a ring on the top outer side and a limiting post on one surface of the ring; an inner cylinder is rotatably fitted with the inner cylinder by a thread; a limiting ring is provided on the inner wall of the inner cylinder; a rotating shaft is fitted on the sampler, and a rotating handle is provided on the top of the rotating shaft; the rotating shaft is rotatably connected to the inner wall of the inner cylinder by a thread. The sampling device, consisting of a support frame and a sampler, has a simple structure, and the rotating handle drives the sampler to sink into the soil for sampling, solving the problem of inconvenient operation of existing sampling devices.

[0004] Although existing technologies can solve the problem of soil sampling, the sampling depth depends on the operator's rotation force and speed, which increases the difficulty of operation and may affect the accuracy of sampling. In addition, the soil sample is collected directly in the sampler during the sampling process, but cannot be collected after the sampling is completed. Furthermore, the device needs to be disassembled one by one, which increases the labor of the staff and makes it inconvenient to remove and disassemble the soil.

[0005] Therefore, we propose a sampling device for evaluating the suitability of soil for agricultural use, which can effectively solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a sampling device for evaluating the suitability of soil for agricultural use, in order to solve the problems mentioned in the background art. When using the current soil sampling device, the device drives the sampler to sink into the soil by rotating the handle, but the sampling depth depends on the operator's rotation force and speed, which not only increases the difficulty of operation but may also affect the accuracy of sampling. In addition, during the sampling process, the soil sample is directly collected in the sampler, but it cannot be collected after the sampling is completed. Furthermore, the device needs to be disassembled one by one, which increases the labor of the staff and makes it inconvenient to remove and disassemble the soil.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sampling device for evaluating the suitability of soil for agricultural use, comprising a trolley frame, rollers symmetrically arranged at the bottom of both sides of the trolley frame, hydraulic cylinder bodies symmetrically arranged at the bottom of both sides of the trolley frame, a positioning plate fixedly installed at the output end of the hydraulic cylinder body, a sliding groove opened inside the right side of the trolley frame, and a through groove opened inside the left side of the trolley frame; a protective cover is screwed to the right side of the trolley frame, and a servo motor body is arranged on the inner top wall of the protective cover, the output shaft of the servo motor body is fixedly installed with a screw rod through a coupling, and a threaded sleeve is movably connected to the outer wall of the screw rod; a movable plate is fixedly installed on the left side of the threaded sleeve, and a limiting component for disassembly and assembly is arranged at the top of the movable plate, and a driving component for sampling is arranged inside the limiting component, the driving component including a driving motor body.

[0025] 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.

[0026] Please see Figures 1-6 The present invention provides the following technical solution:

[0027] Example 1: To address the shortcomings of existing soil sampling devices on the market, where the sampling depth depends on the operator's rotation force and speed (increasing operational difficulty and potentially affecting sampling accuracy), and where soil samples are collected directly within the sampler but cannot be collected after sampling, this example discloses the following technical details for a soil agricultural suitability assessment sampling device. (See attached document for details.) Figure 1 - Appendix Figure 5 The system includes a trolley frame 1, with rollers 2 symmetrically arranged on the bottom of both sides of the trolley frame 1, and hydraulic cylinder bodies 3 symmetrically arranged on the bottom of both sides of the trolley frame 1. A positioning plate 4 is fixedly installed at the output end of the hydraulic cylinder body 3. A sliding groove 5 is opened inside the right side of the trolley frame 1, and a through groove is opened inside the left side of the trolley frame 1. A protective cover is screwed to the right side of the trolley frame 1, and a servo motor body 7 is installed on the inner top wall of the protective cover. A screw 8 is fixedly installed on the output shaft of the servo motor body 7 via a coupling, and a threaded sleeve 9 is movably connected to the outer wall of the screw 8. A movable plate 12 is fixedly installed on the left side of the threaded sleeve 9, and a limit assembly for disassembly and assembly is provided on the top of the movable plate 12. The component has an internal drive assembly for sampling, which includes a drive motor body 17; guide sleeves 10 are fixedly installed on the front and rear sides of the threaded sleeve 9, and guide rods 11 pass through the inside of the guide sleeves 10, with the two ends of the guide rods 11 fixedly connected to the trolley frame 1; a rotating rod 18 is fixedly installed on the output shaft of the drive motor body 17 through a coupling, and a spiral blade 19 is fixedly installed on the outer wall of the rotating rod 18; a sealing cover 20 is fixedly connected to the outer wall of the drive motor body 17; the threaded sleeve 9 is tightly fitted with the guide sleeves 10 and the moving plate 12, and the guide sleeves 10 and the guide rods 11 are movably connected, while the moving plate 12 and the slide groove 5 are slidably connected.

[0028] The device is easily moved by staff pushing the trolley frame 1 and using rollers 2. The trolley frame 1 then moves the sampling cylinder 22 to the location where the soil needs agricultural suitability assessment. An external control panel activates the hydraulic cylinder body 3, causing its output end to move the positioning plate 4 downwards until it contacts the ground, thus fixing the trolley frame 1 and ensuring stability during sampling. This achieves the movement and fixation of the sampling device. Then, the external control panel activates the servo motor body 7, whose output shaft drives the screw 8 to rotate. The rotation of the screw 8 drives the threaded sleeve 9 to move vertically. During the movement of the threaded sleeve 9, the guide sleeve 10 moves on the corresponding guide rod 11, increasing... The conductivity and stability of the threaded sleeve 9 allow it to move, causing the moving plate 12 to slide within the groove 5. This, in turn, drives the sampling cylinder 22 to move into the soil via the limiting component, thus adjusting the depth of the sampling device. When the sampling cylinder 22 is inserted into the appropriate position in the soil, the drive motor body 17 is activated via an external control board. The output shaft of the drive motor body 17 drives the rotating rod 18 to rotate. The rotation of the rotating rod 18 drives the spiral blade 19 to rotate within the sampling cylinder 22, causing the spiral blade 19 to carry the soil upward within the sampling cylinder 22. Thus, the soil passes through the sampling cylinder 22 and enters the collection box 21, enabling soil sampling and collection for subsequent evaluation of the soil's suitability for agricultural use.

[0029] Example 2: The sampling device for evaluating the suitability of soil for agricultural use in this example discloses the following technical content, which facilitates the extraction and easy disassembly of the collected soil. Please refer to the attached document. Figure 1 - Appendix Figure 6 The limiting assembly includes a support plate 13, a first limiting plate 14 hinged to the rear of the support plate 13, a second limiting plate 15 hinged to the front of the support plate 13, a fastening bolt 16 threaded inside the second limiting plate 15, and the end of the fastening bolt 16 inserted into the first limiting plate 14; a collection box 21 is movably connected to the bottom of the sealing cover 20, a sampling cylinder 22 is fixedly connected to the bottom of the collection box 21, and a threaded plate is fixedly connected to the outer wall of the sampling cylinder 22; a positioning bolt 6 is threaded inside the sealing cover 20; the first limiting plate 14 and the second limiting plate 15 are detachably connected to the drive motor body 17, and both the first limiting plate 14 and the second limiting plate 15 are set as semi-circular arc structures; the sealing cover 20 is detachably connected to the collection box 21, and the collection box 21 is connected to the sampling cylinder 22.

[0030] After soil sampling is completed, the sampling cylinder 22 is moved upward to a suitable position by the cooperation of the screw 8 and the threaded sleeve 9. Then, the staff manually opens each fastening bolt 16 in sequence, so that the first limiting plate 14 and the second limiting plate 15 connected by the hinge rotate outward on the support plate 13, thereby disengaging from the drive motor body 17 and the sealing cover 20, making it easy to disassemble the sampling cylinder 22. Then, the staff manually pulls out each positioning bolt 6 to disengage from the sealing cover 20. Then, the staff manually moves the sealing cover 20 upward, so that the sealing cover 20 drives the drive motor body 17 to move upward through the spiral blade 19 connected by the rotating rod 18 until it disengages from the collection box 21, thereby taking out the soil sampled in the collection box 21, realizing the removal of the collected soil and convenient disassembly.
