Soil is composed of minerals formed from the weathering of rocks, organic matter produced by the decomposition of plant and animal remains and microbial remains, soil organisms (solid phase substances), water (liquid phase substances), air (gas phase substances), oxidized humus, etc.

[0003] The existing technology has the following technical problems: When testing soil, it is necessary to carry different equipment for sampling and testing. Carrying more equipment increases the transportation difficulty for operators, makes it inconvenient to carry, and makes it difficult to quickly sample and test different areas, thus reducing the efficiency of the testing work. Utility Model Content

[0004] The technical problem this utility model aims to solve is that current soil testing requires carrying different equipment for sampling and testing. Carrying too much equipment increases the difficulty of transportation for operators, makes it inconvenient to carry, and makes it difficult to quickly sample and test different areas, thus reducing the efficiency of the testing work.

[0005] This utility model discloses a portable rapid soil testing device for forest areas, comprising a movable box, a pull rod installed on one side of the movable box, and four casters fixed at the four corners of the lower end of the movable box. A sampling component is installed inside the other side of the movable box for soil sampling. Positioning components are installed at the four corners of the outer side of the movable box for fixing the movable box. Each positioning component includes a fixing rod located at one corner of the movable box. A storage slot is provided on the movable box corresponding to the fixing rod, and the fixing rod is located within the storage slot. A rotating shaft is fixed to one end of the fixing rod, and the rotating shaft is rotatably connected to the movable box. Support feet are fixed at the top corner of the movable box on the side away from the pull rod.

[0006] The sampling assembly includes a sampling screw, which is vertically disposed inside the movable housing and rotatably connected to the movable housing. The top end of the sampling screw extends to the outer side of the top end of the movable housing. A rotating handle is fixed to one end of the sampling screw located on the outer side of the top end of the movable housing. A sampling rod is disposed on the outer side of the lower end of the sampling screw and is threadedly connected to the sampling screw. A sampling head is detachably connected to the lower end of the sampling screw. The lower end of the sampling rod extends to the outer side of the lower end of the movable housing. Two limiting sliders are symmetrically fixed to the outer side of the top end of the sampling screw, and the limiting sliders are slidably connected to the movable housing.

[0007] The positioning assembly further includes a connecting shaft, which is disposed on the inner side of the fixed rod at the end away from the rotating shaft. The connecting shaft is fixedly connected to the fixed rod. A connecting rod is rotatably connected to the outer side of the connecting shaft. A fixed toothed plate is fixed to the end of the connecting rod away from the connecting shaft. A rotating plate is fixed to one end of the rotating shaft. The rotating plate is rotatably connected to the movable housing. Multiple connecting rods are evenly distributed on the side of the rotating plate away from the rotating shaft. A limit assembly is provided inside the movable housing at a position corresponding to the connecting rod.

[0008] The limiting component includes a moving rod, which is horizontally arranged on the inner side of the movable box and at a position corresponding to the rotating plate. The moving plate is fixed to one end of the moving rod near the rotating plate and is slidably connected to the movable box. Multiple limiting bolts are evenly distributed on the side of the moving plate near the rotating plate. The limiting bolts are inserted into the rotating plate through limiting holes. The other end of the moving rod extends to the outer side of the movable box, and a lifting handle is fixed to one end of the moving rod located on the outer side of the movable box.

[0009] A limiting spring is fitted on the outside of the moving rod. One end of the limiting spring is fixedly connected to the moving plate, and the other end of the limiting spring is fixedly connected to the moving box.

[0010] The movable housing has a placement slot on the side near the pull rod, and the main body of the detector is placed in the placement slot. A cover plate is hinged to the movable housing at the position corresponding to the main body of the detector.

[0011] Compared with the prior art, the beneficial effects of this utility model are: through the coordinated structural design of the pull rod, the moving wheel and the positioning component, the mobile box can be moved by the pull rod and the moving wheel. When it is moved to the position where sampling is required, the mobile box can be positioned and fixed to the ground by the positioning component to prevent displacement of the mobile box. Then, the soil can be sampled and tested by the sampling component, thereby effectively improving the convenience of moving the device and enhancing the practicality of the device.

[0012] The structural design of the limiting component enables rapid and effective rotational limiting of the rotating shaft. This limits the rotation of the fixed rod after it rotates to the point where the fixed tooth plate contacts the ground, preventing further rotation. When testing is required, the fixed rod can be stored in the storage slot, and the moving box can be placed horizontally. The moving box is supported by the support feet and two fixed tooth plates on the same side as the support feet. Then, the cover can be opened, and the soil can be placed inside the main body of the detector for rapid testing, improving the ease of use of the device. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] Example 1, such as Figures 1-5 As shown, the device includes a movable housing 1, with a pull rod 3 installed on one side. Four wheels 2 are fixed at the four corners of the lower end of the movable housing 1. A sampling component is installed inside the other side of the movable housing 1 for soil sampling. Positioning components are installed at the four corners of the outer side of the movable housing 1 to fix it in place. Each positioning component includes a fixing rod 6, located at one corner of the movable housing 1. To facilitate storage of the fixing rod 6, a storage slot is provided at the corresponding position on the movable housing 1, where the fixing rod 6 is located. A rotating shaft 14 is fixed to one end of the fixing rod 6, and the rotating shaft 14 is rotatably connected to the movable housing 1. To ensure stability when the device is laid flat, support feet 10 are fixed at the top corner of the movable housing 1 on the side away from the pull rod 3. The positioning component also includes a connecting shaft 11, which is located at the four corners of the movable housing 1. On the inner side of the end of rod 6 away from the rotating shaft 14, the connecting shaft 11 is fixedly connected to the fixed rod 6. In order to facilitate the limiting of the movable box 1 and prevent the movable box 1 from shifting, a connecting rod 12 is rotatably connected to the outer side of the connecting shaft 11. A fixed toothed plate 13 is fixed to the end of the connecting rod 12 away from the connecting shaft 11. A rotating plate 15 is fixed to one end of the rotating shaft 14. The rotating plate 15 is rotatably connected to the movable box 1. Multiple connecting rods 12 are evenly provided on the side of the rotating plate 15 away from the rotating shaft 14. In order to facilitate the limiting of the rotation of the rotating shaft 14 through the connecting rods 12 and the rotating plate 15, a limiting component is provided on the inner side of the movable box 1 at the position corresponding to the connecting rods 12. In order to facilitate the rapid testing of the soil after sampling, a placement groove is provided on the side of the movable box 1 near the pull rod 3. The main body of the detector 23 is placed in the placement groove. A cover plate 22 is hinged to the position of the movable box 1 corresponding to the main body of the detector 23.

[0023] The sampling assembly includes a sampling screw 7, which is vertically positioned inside the movable housing 1 and rotatably connected to the movable housing 1. The top end of the sampling screw 7 extends to the outer side of the top end of the movable housing 1. To facilitate the rotation of the sampling screw 7, a rotating handle 9 is fixed to one end of the sampling screw 7 located on the outer side of the top end of the movable housing 1. A sampling rod 5 is provided on the outer side of the lower end of the sampling screw 7 and is threadedly connected to the sampling screw 7. To facilitate soil sampling, a sampling head 4 is detachably connected to the lower end of the sampling screw 7. The lower end of the sampling rod 5 extends to the outer side of the lower end of the movable housing 1. Two limiting sliders 8 are symmetrically fixed on the outer side of the top end of the sampling screw 7 and are slidably connected to the movable housing 1.

[0024] During operation, when sampling is required, first, pull rod 3 is extended to a suitable length. Then, by pulling rod 3, the device is moved. When it reaches the sampling position, the limiting component is released from limiting the rotating shaft 14. Then, the fixed rod 6 is rotated. When the fixed rod 6 rotates, it drives the connecting rod 12 and the fixed toothed plate 13 to rotate simultaneously around the rotating shaft 14. After the fixed toothed plate 13 rotates to contact the ground, the limiting component limits the rotating shaft 14, preventing the fixed rod 6 and the fixed toothed plate 13 from rotating, thus completing the positioning and fixing of the moving box 1. Then, by rotating the rotating handle 9, the sampling screw 7 is rotated. When the sampling screw 7 rotates, the sampling rod 5 can slide along the axial direction of the sampling rod 5 under the limiting action of the limiting slider 8. This allows the sampling screw 7 to drive the threaded sampling rod 5 to move along the axial direction of the sampling screw 7, thereby driving the sampling head 4 to move. Finally, the sampling head 4 completes the soil sampling process. After the soil sample is taken out, it is placed inside the main body 23 of the detector by opening the cover plate 22 for testing. The coordinated structure of the pull rod 3, moving wheels 2, and positioning components allows the mobile container 1 to be moved. When moved to the sampling location, the positioning components can fix the mobile container 1 to the ground to prevent displacement. The soil can then be sampled and tested using the sampling components, thus effectively improving the ease of movement and practicality of the device.

[0025] Example 2, as Figure 3 and Figure 4 As shown, the limiting assembly includes a moving rod 16, which is horizontally arranged inside the moving housing 1 and at a position corresponding to the rotating plate 15. A moving plate 17 is fixed to one end of the moving rod 16 near the rotating plate 15. The moving plate 17 is slidably connected to the moving housing 1. Multiple limiting bolts 20 are evenly provided on one side of the moving plate 17 near the rotating plate 15. The limiting bolts 20 are inserted into the rotating plate 15 through limiting holes 21. The other end of the moving rod 16 extends to the outside of the moving housing 1. A lifting handle 18 is fixed to one end of the moving rod 16 located on the outside of the moving housing 1. A limiting spring 19 is sleeved on the outside of the moving rod 16. One end of the limiting spring 19 is fixedly connected to the moving plate 17, and the other end of the limiting spring 19 is fixedly connected to the moving housing 1.

[0026] When it is necessary to release the limit on the rotating shaft 14, first pull the lifting handle 18 away from the rotating plate 15. This causes the lifting handle 18 to move the moving plate 17 and the limit bolt 20 simultaneously via the moving rod 16. When the limit bolt 20 moves to the point of disengagement from the limit hole 21, the limit bolt 20 releases the rotational limit on the rotating plate 15, thus releasing the limit on the rotating shaft 14. When it is necessary to limit the rotating shaft 14, release the lifting handle 18. At this time, under the elastic action of the limit spring 19, the moving plate 17 is pushed towards the rotating plate 15. When the moving plate 17 moves, it causes the limit bolt 20 to move simultaneously. When the limit bolt 20 moves to the inside of the limit hole 21, the limit bolt 20 completes the rotational limit on the rotating plate 15. Thus, the rotational limit on the rotating shaft 14 is completed by limiting the rotating plate 15.

[0027] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
