Description

Technical Field

[0001] This utility model relates to the field of farmland improvement technology, and more specifically, it relates to a soil sampler for farmland improvement. Background Technology

[0002] Farmland improvement refers to the general term for measures taken to transform and develop farmland in order to utilize and modify nature, develop agricultural production, and achieve stable and high yields. These measures include leveling land, building terraces, transforming sloping farmland, improving soil, creating farmland shelterbelts, and constructing farmland irrigation systems. To improve the efficiency of basic farmland construction, multiple projects need to be coordinated during implementation, adhering to the principle of integrated management of mountains, water, fields, forests, and roads. Soil sampling and testing are required before any improvement work begins.

[0003] For example, the soil sampler for farmland improvement disclosed in patent announcement number CN217466286U is fixed by placing a stabilizing base on the farmland and having the user step on the side of the stabilizing base for fixation. Then, the drive motor is powered on and drives the chassis to rotate through the steering reducer. The sampling tube, which is composed of arc-shaped plates, rotates with the chassis. The serrations of the sampling tube facilitate drilling into the soil. After reaching the predetermined drilling depth, the sampling device is slightly shaken, and then the sample in the sampling tube is lifted together by pulling the pressure rod. After the sampling device is laid down, the sampling tube is pushed out of the interior of the stabilizing base by pushing the pressure rod. The arc-shaped plates are separated by the hinge between the arc-shaped plates and the chassis to facilitate the removal of the complete soil sample.

[0004] In the above scheme, the shape of the stabilizing seat is fixed. However, in actual use, the terrain of farmland is diverse, and the stabilizing seat that cannot be systematically adjusted will have insufficient stability during use. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a more stable soil sampler for farmland improvement.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A soil sampler for farmland improvement includes a pressure rod and a mounting housing located below and connected to the pressure rod. The mounting housing contains a mounting bracket connected to the mounting housing.

[0008] The pressure rod is hollow inside, and an adjusting screw is installed inside. One end of the adjusting screw passes through a mounting bracket, which houses a rotary motor. The output end of the rotary motor is connected to a gear, which meshes with the adjusting screw. A sampling tube is connected to one end of the adjusting screw.

[0009] Two symmetrical slots are formed on the outer perimeter of the mounting housing. Two sets of stabilizing seats are engaged within these slots. Each stabilizing seat includes a fixing block and a stabilizing component placed within the fixing block. A through slot is formed within the fixing block, and a drive motor is located on one side of the through slot. A gear is fixedly connected to the output end of the drive motor.

[0010] The stabilizing component includes a nail plate and a rotating rod connected to the nail plate. The outer peripheral wall of the rotating rod is threaded, and the rotating rod meshes with a gear. The nail plate and the rotating rod are rotatably connected.

[0011] The present invention is further configured such that: the fixed block includes a main body and a rotating block, the main body and the rotating block are hinged together, and a baffle is provided on the lower end face of the main body to prevent the rotating block from flipping over.

[0012] The present invention is further configured such that: the lower end of the adjusting screw is threaded, and the sampling tube is connected to the adjusting screw by the thread.

[0013] The present invention is further configured such that the sampling tube is composed of several threaded sub-tubes.

[0014] The present invention is further configured such that: a panel is provided on the mounting shell corresponding to the sampling tube, and the panel is connected to the mounting shell by a pin.

[0015] Compared with the shortcomings of the prior art, the beneficial effects of this utility model are as follows:

[0016] Adjustable stabilizing bases on both sides of the mounting housing adapt to uneven farmland terrain, ensuring the equipment remains stable on various surfaces. A nail plate is located beneath the stabilizing base to prevent slippage during operation. Furthermore, the stabilizing base and mounting housing are detachable for easy transport and storage. The sampling tube is designed as a detachable module, allowing for different lengths to suit various soil sampling needs. Removing the corresponding secondary tube prevents soil sample contamination.

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] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Working principle: In use, first remove the panel 19, then install the corresponding number of auxiliary tubes 18 according to the soil conditions to be sampled, then install the panel 19, then connect the two stabilizing seats 8 to the mounting shell 2, then extend the stabilizing seats 8, flip the rotating rod 14 into the through groove so that the rotating rod 14 meshes with the gear 12, then drive the two drive motors 11 to rotate so that the nail plates 13 on both sides are in contact with the ground, then drive the rotary motor 5 to rotate, the rotary motor 5 drives the gear 6 to rotate, since the gear 6 meshes with the adjusting screw 4, the rotation of the gear 6 will drive the adjusting screw 4 to move, the displacement of the adjusting screw 4 will drive the sampling tube 7 connected to the adjusting screw 4 to move until the sampling is successful.

[0023] After sampling is completed, open panel 19 and remove the secondary tube 18 filled with sample to complete the soil sampling.

[0024] By connecting the main body 15 and the rotating block 16 with a hinge, the folding and storage of the stabilizer 8 is achieved.

[0025] like Figures 1 to 2 As shown,

[0026] It includes a pressure rod 1 and a mounting housing 2 located below and connected to the pressure rod 1. The mounting housing 2 is provided with a mounting bracket 3 connected to the mounting housing 2. The mounting housing 2 is provided with a panel 19 corresponding to the sampling tube 7. The panel 19 is connected to the mounting housing 2 by a pin. The sampling tube 7 can be taken out from the mounting housing 2 by removing the panel 19.

[0027] The pressure rod 1 is hollow inside, and an adjusting screw 4 is installed inside the pressure rod 1. One end of the adjusting screw 4 passes through the mounting frame 3. A rotary motor 5 is installed inside the mounting frame 3. A gear 6 is connected to the output end of the rotary motor 5. The gear 6 meshes with the adjusting screw 4. The rotary motor 5 rotates to drive the adjusting screw 4 to move, which makes it easy for the user to accurately control the sampling depth of the sampling tube 7.

[0028] One end of the adjusting screw 4 is connected to the sampling tube 7. The lower end of the adjusting screw 4 is threaded, and the sampling tube 7 is connected to the adjusting screw 4 by the thread, which facilitates the installation and removal of the sampling tube 7.

[0029] The sampling tube 7 consists of several threaded sub-tubes 18. By removing the corresponding sub-tubes 18, the soil sample can be prevented from being contaminated.

[0030] Two slots are symmetrically formed on the outer periphery of the mounting housing 2. Two sets of stabilizing seats 8 are engaged in the slots. Each stabilizing seat 8 includes a fixing block 9 and a stabilizing component 10 placed inside the fixing block 9. A through slot is formed in the fixing block 9. A drive motor 11 is provided on one side of the through slot. A gear 12 is fixedly connected to the output end of the drive motor 11. By rotating the drive motor 11, the gear 12 is driven to rotate, thereby adjusting the length of the rotating rod 14 extending out of the through slot, and thus adjusting the height of the stabilizing seat 8 so that both sides of the mounting housing 2 are on the same horizontal plane.

[0031] The fixed block 9 includes a main body 15 and a rotating block 16. The main body 15 and the rotating block 16 are hinged together. The lower end face of the main body 15 is provided with a baffle 17 to prevent the rotating block 16 from flipping over, ensuring that the rotating block 16 can only rotate to one side and avoid affecting the sampling work.

[0032] The stabilizer 10 includes a nail plate 13 and a rotating rod 14 connected to the nail plate 13. The outer peripheral wall of the rotating rod 14 is threaded and meshes with the gear 12. The nail plate 13 is rotatably connected to the rotating rod 14, which can avoid affecting the angle of the nail plate 13 when the drive motor 11 drives the rotating rod 14 to rotate.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
