Description

Technical Field

[0001] This utility model relates to the technical field of soil sampling devices, specifically to a soil sampling device for agricultural technology promotion. Background Technology

[0002] Soil sampling refers to the collection of soil samples from the surface or underground using scientific methods to analyze the physical, chemical, and biological properties of the soil and the content of pollutants. In agricultural technology extension, soil sampling is usually used to assess soil fertility, guide fertilization programs, and monitor crop growth conditions.

[0003] Because agricultural soils are relatively loose and require shallow sampling depths, existing technologies for agricultural soil sampling typically use simple soil drills or electric soil samplers. After inserting the sampling drill bit into the soil, the soil to be sampled is taken out and placed into a pre-prepared sampling box. However, before sampling, it is necessary to determine the sampling points and use methods such as diagonal method, checkerboard method, and quincunx method to take multiple sampling points. After sampling the soil at each sampling point, the sampled soil needs to be removed and the soil in the sampler needs to be cleaned before sampling the next sampling point. This process is cumbersome, time-consuming, and has low sampling efficiency.

[0004] For example, a hard soil sampling drill set with publication number CN218212062U includes a sampling drill device and a drill labor-saving device. The drill labor-saving device comprises two sets of gear transmission mechanisms and a fixed gear mechanism. This device is mainly used for sampling hard soil in the field, allowing users to extract samples with less force. Users step on a pedal and crank the handle up and down; the force on the handle is transmitted through the two sets of gears to the drill rod, causing the drill bit to enter the hard soil and extract the sample. This hard soil sampling drill set is more labor-saving when sampling hard soil, making it convenient for students to collect samples in the field. It is also portable. However, after sampling, the soil inside the drill bit needs to be manually removed, resulting in lower sampling efficiency.

[0005] A soil sampler for forestry soil sampling, disclosed in CN114166554A, includes a central frame. A sliding support frame is slidably mounted on one side of the central frame. A support plate is fixed on the sliding support frame, and a drive device support frame is mounted on the support plate. The drive device support frame is equipped with a small diesel engine and a small differential. A rotating rod is located at the lower end of the small differential, and a spiral blade is fixed on the rotating rod. An electric telescopic rod is mounted on the central frame. Symmetrical wheels are located at the lower end of the central frame. An auxiliary frame is located in the middle of the central frame, and auxiliary wheels are mounted on the auxiliary frame. During movement, the sampler can be hooked onto a pickup truck using hooks on the handles. The user manually drags the device, with the auxiliary wheels and wheels on the ground for easy movement. This facilitates soil sampling. The device is then lifted using the electric telescopic rod for easy soil removal. After sampling, the device is lifted using the electric telescopic rod to remove the soil from the sampler, but the soil still needs to be placed in a separate container. Utility Model Content

[0049] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0050] like Figures 1-4 As shown in the figure, this embodiment proposes a soil sampling device for agricultural technology extension, including a sampling tube 1, a sampling mechanism, a soil sampling mechanism, a sample storage mechanism, and a sampling box replacement mechanism. The sampling mechanism is installed at the bottom end of the sampling tube 1, the soil sampling mechanism is installed on the side wall of the sampling tube 1, the sample storage mechanism is installed inside the sampling tube 1 for temporarily storing the sampled soil. The sampling box replacement mechanism is installed on the side wall of the sampling tube 1 for automatically replacing the sampling box to hold the sample. When sampling, the sampling point is determined, the sampling mechanism is aligned with the soil at the sampling point and inserted for sampling. The soil sampling mechanism limits the sampling box component, and the soil enters the sampling box component. The soil sampling mechanism releases the limitation on the sampling box component, the sample storage mechanism lifts the sampling box component containing the sample and pushes it to the designated position for storage, and the sampling box replacement mechanism pushes the new sampling box component into the sampling tube 1 to sample the next sampling point. It is not necessary to take out the sample, put it in the box, and then sample the next sampling point, which greatly improves the sampling efficiency and reduces the labor intensity.

[0051] The sampling mechanism includes a sampling drill bit 2 and a sampling head 3. The sampling drill bit 2 is fixedly connected to the bottom end of the sampling tube 1, and the sampling head 3 is located inside the sampling drill bit 2 and fixedly connected inside the sampling tube 1.

[0052] Secondly, the soil sampling mechanism includes a sampling box component, a protective shell 4, spring telescopic rods 5, electromagnetic limiting blocks 6, and an electromagnetic ring 7. The sampling box component is slidably connected inside the sampling tube 1. Two protective shells 4 are provided, and the two protective shells 4 are respectively fixedly connected to both sides of the sampling tube 1. The two protective shells 4 are located inside the sampling drill bit 2. Two spring telescopic rods 5 are provided, and one end of each spring telescopic rod 5 is respectively fixedly connected to the two protective shells 4. Two electromagnetic limiting blocks 6 are provided, and the two electromagnetic limiting blocks 6 are respectively fixedly connected to the other end of each spring telescopic rod 5. The two electromagnetic limiting blocks 6 cooperate with the sampling box component. The electromagnetic ring 7 is fixedly connected to the sampling head 3. The electromagnetic ring 7 and the sampling drill bit 2 are connected to each other. When the sample box component is in place, it slides down from the sample storage mechanism to the bottom of the sampling tube 1. Then, the electromagnetic ring 7 is activated, causing the sample box component to be attracted to the electromagnetic ring 7, ensuring that the sample box component is placed horizontally inside the sampling tube 1. The electromagnetic limiting block 6 is activated, and under the action of magnetic force, the electromagnetic limiting block 6 is attracted to the sample box component and drives the spring telescopic rod 5 to stretch, which plays a fixing role and prevents the soil from putting pressure on the sample box component during sampling, causing it to move upward and preventing the soil from entering the sample box component. After sampling is completed, the electromagnetic limiting block 6 is closed, and the spring telescopic rod 5 retracts to pull the electromagnetic limiting block 6 back. Then, the sample box component loses its limiting position and is attracted and stored by the sample storage mechanism.

[0053] Furthermore, the sampling box component includes a sampling box body 8, a metal ring 9, and a metal disk 10. The sampling box body 8 is slidably connected inside the sampling tube 1. The metal ring 9 is fixedly connected to the open end of the sampling box body 8, and the metal disk 10 is fixedly connected to the closed end of the sampling box body 8. The side wall of the metal ring 9 is provided with an annular groove, which is used to cooperate with the electromagnetic limiting block 6 to hold the sampling box component in place during sampling so that the sample cannot be prevented from entering the sampling box due to upward movement. The metal disk 10 and the metal ring 9 are used in conjunction with the magnetic attraction effect of the electromagnetic ring 7 and the electromagnetic limiting block 6.

[0054] The sample storage mechanism includes a mounting plate 11, a rack 12, an electromagnet 13, a gear 14, a motor 15, a storage box 16, a lid 17, an electric cylinder 18, and a push plate 19. The mounting plate 11 is fixedly connected to the top of the sampling tube 1. The rack 12 is slidably connected to the mounting plate 11. The electromagnet 13 is fixedly connected to the bottom of the rack 12. The gear 14 is rotatably connected to the mounting plate 11 and meshes with the rack 12. The motor 15 is fixedly connected to the mounting plate 11, and its output end is fixedly connected to the gear 14. The storage box 16 is fixedly connected to the side wall of the sampling tube 1 and communicates with the inside of the sampling tube 1. The lid 17 is detachably connected to... At the top of storage box 16, electric cylinder 18 is fixedly connected to the side wall of sampling tube 1 on the opposite side symmetrical about the storage box. Push plate 19 is fixedly connected to the output end of electric cylinder 18. After the sampling box component completes sampling, motor 15 starts, driving gear 14 to rotate, thereby driving rack 12 to move vertically. Rack 12 moves downward, driving electromagnet 13 to move downward and attracting the metal plate 10 of the sampling box component. Motor 15 starts again, driving rack 12 to move upward, driving the sampling box component to the position of storage box 16. Electromagnet 13 stops working, and at the same time, electric cylinder 18 starts, driving push plate to move and push the sampling box component into storage box 16.

[0055] Finally, the sampling box replacement mechanism includes a storage box 20, an electric cylinder 21, and a pusher plate 22. There are two storage boxes 20, which are fixedly connected to both sides of the sampling tube 1 and are connected to the sampling tube 1. The storage boxes 20 contain multiple sampling box components, and the top of the two storage boxes 20 is also provided with a box cover 17. There are two electric cylinders 21, which are fixedly connected to the two storage boxes 20 respectively. There are two pusher plates 22, which are slidably connected to the two storage boxes 20 respectively. The two pusher plates 22 are fixedly connected to the output ends of the two electric cylinders 21 respectively. After the sampling tube 1 component containing the sample is stored in the storage box 16, the electric cylinder 21 is activated, which drives the pusher plate 22 to move and push the new sampling box component into the sampling tube 1. Under the action of gravity, it falls onto the electromagnetic ring 7 and is attracted, and the next round of sampling is carried out.

[0056] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
