A lifting screw is provided in the inner cavity of the externally threaded tube, and a second internally threaded sleeve is threaded onto the lifting screw. This prior art has a reasonable structural design, facilitating efficient sampling of farm soil and reducing the labor intensity of sampling personnel.

[0004] Although using an electric motor to drive the device can improve data collection efficiency and reduce the workload of staff, when used outdoors, the need for the motor to work with a battery significantly increases the overall weight of the device. In addition, during the rainy season, the motor and battery are prone to short circuits due to rainwater seepage. Utility Model Content

[0005] The purpose of this utility model is to provide a land sampling device for land management, which aims to solve the technical problems of using a motor to drive the device, which is beneficial to improve the sampling efficiency and reduce the labor intensity of the staff. However, when used outdoors, the motor needs to be used with a battery, which greatly increases the overall weight of the device. At the same time, in the rainy season, the motor and battery are easily penetrated by rainwater, which can cause short circuit failures.

[0006] To achieve the above objectives, this utility model employs a land sampling device for land management, comprising an installation cylinder, a threaded sleeve rotatably mounted above the installation cylinder via a limiting ring, a driven gear mounted on the threaded sleeve, a lifting screw threaded inside the threaded sleeve, a sampling cylinder mounted below the lifting screw via a fixing member, the sampling cylinder having a conical surface at its lower end and extending into the installation cylinder, an installation box mounted above the installation cylinder, the driven gear extending into the installation box, a driving gear rotatably mounted inside the installation box, the driving gear rotating via a rotating disk, a polygonal rod mounted above the installation box, a polygonal groove inside the lifting screw, and the polygonal rod extending into the polygonal groove.

[0007] The fixing component includes two fixing nuts and a fixing screw. The lower part of the lifting screw has a square groove, and the upper part of the sampling tube has a square block, which is inserted into the square groove. The two fixing nuts are symmetrically arranged on the two outer sides of the square groove. The fixing screw is also threadedly connected to the corresponding fixing nut and is located between the two fixing nuts, and passes through the lifting screw and the square block.

[0008] The inner wall of the mounting cylinder is provided with multiple C-shaped blocks, and the sampling cylinder is located between the multiple C-shaped blocks.

[0009] The driven gear has a greater number of external teeth than the driving gear, and the driving gear meshes with the driven gear and is located outside the driven gear.

[0010] The land sampling device for land management also includes two foot pedals and a handle. The two foot pedals are fixedly connected to the mounting cylinder and are symmetrically arranged on both sides of the mounting cylinder. The handle is fixedly connected to the mounting cylinder and is located on the outside of the mounting cylinder.

[0011] The land sampling device for land management further includes a scraper sleeve and a push-out plate. The scraper sleeve has a through hole in the middle for the sampling tube to pass through. Two L-shaped rods are arranged above the push-out plate. The sampling tube has two through holes above it. The scraper sleeve is arranged below the mounting tube by multiple connecting rods. The two L-shaped rods are respectively fixedly connected to the mounting tube and located on the two inner sides of the mounting tube, and pass through the corresponding through holes. The inner diameter of the sampling tube is the same as the inner diameter of the push-out plate, and the push-out plate extends to the through hole.

[0012] This utility model discloses a land sampling device for land management. A threaded sleeve is rotatably mounted via a limiting ring. A driven gear is mounted on the threaded sleeve, and a lifting screw is threaded internally within the threaded sleeve. The lifting screw is connected to a sampling cylinder via a fixing member consisting of two fixing nuts and the fixing screw. The sampling cylinder has a tapered surface at its lower end extending into a mounting cylinder. A mounting box is positioned above the mounting cylinder, and a driving gear, meshing with the driven gear, is rotatably mounted within the mounting box. The driving gear rotates via a rotating disk. This manual operation method avoids the use of a motor and battery, preventing a significant increase in the overall weight of the device due to motor and battery components. It also prevents short-circuit failures in the motor and battery due to rainwater seepage during the rainy season. The overall structure effectively overcomes the drawbacks of motor-driven outdoor use while ensuring sampling functionality. Attached Figure Description

Detailed Implementation

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] Please see Figures 1-6 This utility model provides a land sampling device for land management, including an installation cylinder 1. A threaded sleeve 2 is rotatably mounted on the upper part of the installation cylinder 1 via a limiting ring. A driven gear 3 is mounted on the threaded sleeve 2. A lifting screw 4 is threaded inside the threaded sleeve 2. A sampling cylinder 5 is mounted below the lifting screw 4 via a fixing member. The sampling cylinder 5 has a conical surface 6 at its lower part and extends into the installation cylinder 1. An installation box 7 is mounted on the upper part of the installation cylinder 1, and the driven gear 3 extends into the installation box 7. A driving gear 8 is rotatably mounted inside the installation box 7 and rotates via a rotating disk 9. A polygonal rod 22 is mounted on the upper part of the installation box 7. A polygonal groove 23 is located inside the lifting screw 4, and the polygonal rod 22 extends into the polygonal groove 23.

[0023] In this embodiment, this design allows the threaded sleeve 2 to rotate flexibly within a specific range, providing a foundation for the subsequent transmission structure. The driven gear 3 is mounted on the threaded sleeve 2, cooperating with the driving gear 8, which rotates via the rotating disk 9 within the mounting box 7, forming a gear transmission system. Manually rotating the rotating disk 9 drives the driving gear 8, which in turn drives the driven gear 3 and the threaded sleeve 2 to rotate. A lifting screw 4 is threaded into the threaded sleeve 2. As the threaded sleeve 2 rotates, the lifting screw 4 can move up and down, thereby driving the sampling cylinder 5, connected below by the fixing component, to move up and down, thus achieving soil sampling. This structure eliminates the need for a motor drive, avoiding the increased weight and short-circuit issues associated with using a motor and battery outdoors, especially during the rainy season. Furthermore, the manual operation method is simple and reliable, reducing device cost and maintenance difficulty, and improving the device's applicability and stability in outdoor environments.

[0024] Furthermore, the fixing component includes two fixing nuts 10 and a fixing screw 11. The lower part of the lifting screw 4 has a square groove 12, and the upper part of the sampling cylinder 5 has a square block 13, which is inserted into the square groove 12. The two fixing nuts 10 are symmetrically arranged on the two outer sides of the square groove 12. The fixing screw 11 is also threadedly connected to the corresponding fixing nut 10 and is located between the two fixing nuts 10, and passes through the lifting screw 4 and the square block 13.

[0025] In this embodiment, the square block 13 is inserted into the square groove 12, achieving initial positioning and connection between the sampling cylinder 5 and the lifting screw 4, preventing relative rotation between them. Two fixing nuts 10 are symmetrically arranged on the outer sides of the square groove 12. The fixing screw 11 passes through the lifting screw 4 and the square block 13 and is threadedly connected to the corresponding fixing nut 10, located between the two fixing nuts 10. This connection method further enhances the connection strength and stability between the sampling cylinder 5 and the lifting screw 4, ensuring that the sampling cylinder 5 will not loosen or fall off due to force during sampling, guaranteeing the smooth progress of sampling work and improving the reliability and durability of the device.

[0026] Furthermore, the inner wall of the mounting cylinder 1 is provided with a plurality of C-shaped blocks 14, and the sampling cylinder 5 is located between the plurality of C-shaped blocks 14.

[0027] In this embodiment, the multiple C-shaped blocks can effectively limit and guide the sampling cylinder 5, preventing it from shifting or shaking during lifting and lowering. This ensures that the sampling cylinder 5 can be accurately and vertically inserted into the soil for sampling, thus improving the accuracy and quality of the sampling.

[0028] Furthermore, the number of external teeth of the driven gear 3 is greater than the number of external teeth of the driving gear 8, and the driving gear 8 meshes with the driven gear 3 and is located outside the driven gear 3.

[0029] In this embodiment, when the driving gear 8 is rotated via the rotating disk 9, the driving gear 8 has fewer teeth and passes through fewer teeth in one revolution, while the driven gear 3 meshes with it has more teeth. According to the gear transmission principle, the driven gear 3 will rotate at a slower speed but will transmit a larger torque. This design allows the operator to input a smaller force when rotating the rotating disk 9, and amplify the torque through the gear transmission system, thereby more easily driving the threaded sleeve 2 and the lifting screw 4, and driving the sampling cylinder 5 to perform sampling operations. This effectively reduces the labor intensity of the operator and improves the sampling efficiency, and is especially suitable for land environments that require frequent sampling or have high sampling resistance.

[0030] Furthermore, the land sampling device for land management also includes two foot pedals 15 and a handle 16. The two foot pedals 15 are respectively fixedly connected to the mounting cylinder 1 and are symmetrically arranged on both sides of the mounting cylinder 1. The handle 16 is fixedly connected to the mounting cylinder 1 and is located on the outside of the mounting cylinder 1.

[0031] In this embodiment, when the operator is conducting land sampling, he / she can step on the foot pedal 15 to increase the stability between the body and the device, prevent the device from shaking or tilting during forceful operation, and ensure the accuracy and safety of the sampling operation; before sampling, the operator can move the device to the designated location by holding the handle 16.

[0032] Furthermore, the land sampling device for land management also includes a scraper sleeve 17 and a push-out plate 18. The scraper sleeve 17 has a through hole 19 in the middle for the sampling cylinder 5 to pass through. Two L-shaped rods 20 are arranged above the push-out plate 18. The sampling cylinder 5 has two through holes 21 above it. The scraper sleeve 17 is arranged below the mounting cylinder 1 by multiple connecting rods. The two L-shaped rods 20 are respectively fixedly connected to the mounting cylinder 1 and located on the two inner sides of the mounting cylinder 1, and pass through the corresponding through holes 21. The inner diameter of the sampling cylinder 5 is the same as the inner diameter of the push-out plate 18, and the push-out plate 18 extends to the through hole 19.

[0033] In this embodiment, during the upward movement of the sampling cylinder 5, the scraper sleeve 17 can scrape away the soil adhering to the outer wall of the sampling cylinder 5, preventing soil from being brought into the device and affecting the normal operation of other components. It also ensures the purity of the sampled soil, facilitating subsequent analysis and research of the sampled soil. When sampling is completed, the push-out plate 18 is located at the inner top of the sampling cylinder 5. Then, by rotating the lifting screw 4 in the opposite direction, the sampling cylinder 5 moves towards the mounting cylinder 1. At this time, the push-out plate 18 can push out the soil in the sampling cylinder 5 completely and smoothly, avoiding soil residue in the sampling cylinder 5, improving the integrity and efficiency of sampling, and enabling the device to complete the land sampling task more efficiently.

[0034] When using this utility model, the operator first moves the device to the location of the land to be sampled, holds the handle 16 with both hands to keep the device stable, and places both feet on the two foot pedals 15 symmetrically arranged on both sides of the mounting cylinder 1 to further increase stability; then, the operator rotates the rotating disk 9 on the mounting box 7 by hand, which drives the connected drive gear 8 to rotate. Since the drive gear 8 meshes with the driven gear 3 and the driven gear 3 has more external teeth, the torque is amplified through gear transmission, causing the threaded sleeve 2 to rotate, thereby driving the lifting screw 4 connected to the internal thread of the threaded sleeve 2 to move downward. The lifting screw 4 is fixed by a fixing member belt that is fixedly connected by two fixing nuts 10 and fixing screw 11. The sampling cylinder 5, with a conical surface 6 at its lower part, is vertically inserted into the soil. After sampling, the rotating disk 9 is rotated in the opposite direction, causing the lifting screw 4 to lift the sampling cylinder 5. At this time, the scraper sleeve 17, which is located below the mounting cylinder 1 and connected by multiple connecting rods, scrapes away the soil attached to the outer wall of the sampling cylinder 5. Simultaneously, the push-out plate 18 is located at the inner top of the sampling cylinder 5. By rotating the lifting screw 4 in the opposite direction, the sampling cylinder 5 moves towards the mounting cylinder 1. At this time, the push-out plate 18 can push out the soil in the sampling cylinder 5 completely and smoothly, avoiding soil residue in the sampling cylinder 5, improving the integrity and efficiency of sampling, and enabling the device to complete the land sampling task more efficiently.

[0035] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
