[0022] 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. Example 1

[0023] like Figure 1 - Figure 6 As shown, this utility model provides a technical solution: a soil testing and sampling device, comprising: a testing mechanism 1, an internal loading and unloading mechanism 2, the testing mechanism 1 including a handle 11, a shovel head 12 fixedly connected to one side of the handle 11, a U-shaped plate 13 slidably engaged in the middle of the shovel head 12, a connecting strip 14 fixedly connected to one side of the bottom of the U-shaped plate 13, a limiting post 15 fixedly connected to one side of the connecting strip 14, limiting plates 16 slidably connected to both sides of the inner side of the limiting post 15, a limiting post 2 17 provided at the bottom of the limiting post 15, sliding plates 18 slidably connected to both sides of the inner side of the limiting post 2 17, a connecting strip 2 19 fixedly connected to one side of the limiting post 2 17, a moving plate 101 fixedly connected to one side of the connecting strip 2 19, and a test strip 102 provided at the top of the moving plate 101.

[0024] In this embodiment, the bottom of the handle 11 is fixedly connected to the top of the shovel head 12. The bottom of the shovel head 12 is sloped, allowing it to penetrate deeper into the soil. A groove is provided inside the shovel head 12. One side of the U-shaped plate 13 is slidably connected to the groove inside the shovel head 12, and a corresponding slot is provided on one side of the shovel head 12. The U-shaped plate 13 perfectly corresponds to the U-shaped plate 13, preventing soil clods from entering the shovel head 12 during operation. A connecting strip 14 is fixedly connected to one side of the U-shaped plate 13, and a limiting post 15 is fixedly connected to one side of the connecting strip 14. A sliding groove is provided in the handle 11 corresponding to the position of the limiting post 15. The outer side of the limiting post 15 is slidably connected to the sliding groove on one side of the handle 11. Pushing the limiting post 15 into the handle 11 and pulling it to one side will... Moving the connecting strip 14 to one side causes the U-shaped plate 13 to move to one side as well. This movement exposes the slot on one side of the shovel head 12. Limiting plates 16 are slidably connected to both sides of the inner side of the limiting post 15. A spring is fixedly connected to the middle of the two limiting plates 16, ensuring that the limiting plates 16 are constantly subjected to an outward pushing force. Limiting holes corresponding to the positions of the limiting plates 16 are provided on both sides of the handle 11. The bottom side of the limiting plate 16 is slidably connected to a limiting hole on one side of the handle 11, preventing the limiting post 15 from moving and thus restricting its position. A limiting hole is provided at the bottom of the sliding groove of the limiting post 15 to limit its position after sliding. When the limiting hole restricts the movement, the U-shaped plate 13 fixedly connected to the bottom of the connecting strip 14 will completely detach from the groove on one side of the shovel head 12. To release the restriction, simply pinch the connector on the top side of the limiting plate 16. The springs in the middle of the two limiting plates 16 will contract under force, causing the bottom of the limiting plate 16 to detach from the limiting hole on one side of the handle 11. At this time, the limiting post 15 can be moved freely. The bottom of the limiting post 15 is provided with a limiting post 2 17. Sliding plates 18 are slidably connected to both sides of the inner side of the limiting post 2 17. Springs are fixedly connected to the middle of the two sliding plates 18, so that the two sliding plates 18 are always subjected to an outward pushing force. Limiting holes corresponding to the positions of the sliding plates 18 are opened on both sides of the handle 11. The bottom side of the sliding plate 18 is connected to the side of the handle 11. The limiting hole is slidably connected, preventing the second limiting post 17 from moving, thus restricting its position. A connecting strip 19 is fixedly connected to one side of the second limiting post 17, and one side of the connecting strip 19 is fixedly connected to one side of the moving plate 101. Moving the second limiting post 17 will cause the connecting strip 19 to move, which in turn will cause the moving plate 101 to move. When the second limiting post 17 reaches the bottom limiting hole, gently pressing it inward will cause the sliding plates 18 on both sides to be pushed by springs and slide into the limiting hole on one side of the handle 11, thus restricting its position. The bottom moving plate 101 will engage with the groove on one side of the shovel head 12. A test strip 102 is provided on one side of the moving plate 101. After water is added…When soil clods come into contact with water, they react with test strip 102, thus allowing for the detection of the soil's acidity or alkalinity. Example 2

[0025] like Figure 1 - Figure 6 As shown, the loading and unloading mechanism 2 includes four rotating columns 21, and each of the four rotating columns 21 is fixedly connected to a limiting plate 22. Limiting springs 23 are slidably connected to the outer side of the four limiting plates 22.

[0026] In this embodiment, four rotating columns 21 are rectangularly distributed on the top of the movable plate 101. A limiting plate 22 is fixedly connected to the bottom of the rotating columns 21. A limiting spring 23 is slidably connected to the outer side of the limiting plate 22. The top of the limiting spring 23 is hooked to the bottom of the rotating column 21. The rotation of the rotating column 21 will drive the limiting plate 22 and the limiting spring 23 to rotate. A cylindrical groove is opened on the top of the movable plate 101 corresponding to the position of the limiting plate 22. A slot is opened at the bottom of the groove to accommodate the limiting plate 22. A limiting groove is also opened at the bottom of the cylindrical groove. The bottom of the limiting plate 22 can be engaged with it. The bottom of the limiting plate 22 extends into the bottom of the cylindrical groove. After passing through the bottom of the cylindrical groove, the rotating column 21 rotates. 1. The rotating column 21 drives the limiting plate 22 to rotate. The bottom of the limiting plate 22 rotates and engages with the bottom limiting groove of the cylindrical groove, thus fixing the position of the rotating column 21. The outer side of the rotating column 21 is slidably connected to the inside of the test strip 102. The fixed position of the rotating column 21 also fixes the position of the test strip 102. When the test strip 102 needs to be replaced, simply rotate the rotating column 21 in the opposite direction to release the bottom of the limiting plate 22 from the limiting groove. The limiting spring 23 pushes the limiting plate 22 out by its own thrust, and the rotating column 21 is removed from the top groove of the moving plate 101. Replace the new moving plate 101, and then engage the four rotating columns 21 in sequence to quickly fix the test strip 102.

[0027] Working principle: Hold the handle 11 and forcefully insert the shovel head 12 into the soil where the acidity / alkalinity needs to be tested. Stop after inserting to a suitable distance. Then, pinch the connecting pieces extending from both sides of 1 and 6, causing the spring in the middle of the limiting plate 16 to contract under pressure. The bottom of the limiting plate 16 will disengage from the limiting hole on one side of the handle 11, pushing the limiting post 15 into the handle 11. While moving to one side, the U-shaped plate 13 at the bottom, affected by the limiting post 15, will also penetrate a little deeper into the shovel head 12, thus disengaging from the groove on one side of the shovel head 12. Then, it will move to one side. When the limiting post 15 slides to the bottom of the chute, the limiting plates 16 on both sides will engage with the opening. The limiting hole engages, thus restricting the position of the limiting post 15 and preventing it from moving arbitrarily. At this time, the U-shaped plate 13 is completely disengaged from the groove on one side of the shovel head 12. Then, the limiting post 17 is released and pulled to one side, causing the bottom-fixed limiting post 17 to move along with it. When the limiting post 17 slides into the sliding groove limiting hole, it is gently pushed into the handle 11. The sliding plates 18 on both sides are engaged with the limiting holes on both sides of the handle 11 by the spring force, so that the position of the limiting post 17 is limited after moving a certain distance into the handle 11. At this time, the bottom-fixed moving plate 101 and the side of the shovel head 12 are engaged. With the slot engaged, one side of the test strip 102 contacts the soil clod. A suitable amount of water is then poured in. After the water and soil clod mix, a reaction occurs on the surface of the test strip 102. The reaction result indicates the soil's acidity or alkalinity. When the test strip 102 needs replacement, manually rotate the rotating columns 21 at the four corners of the moving plate 101. The bottom of the limiting plate 22 disengages from the internal limiting groove on the top side of the moving plate 101. The limiting spring 23 pushes the limiting plate 22 out, allowing a new test strip 102 to be replaced. Rotating the rotating columns 21 again secures the test strip 102 for reuse. To release the engagement between the moving plate 101 and one side of the shovel head 12, simply pinch the sliding plate. On one side of 18, the spring in the middle of the sliding plates 18 on both sides is compressed, causing the bottom of the sliding plate 18 to fall out of the limiting grooves on both sides of the handle 11. Then, the second limiting post 17 is moved to one side and pulled outward, so that the sliding plate 18 slides to the top of the sliding groove. At this time, the sliding plate 18 inside the second limiting post 17 restricts the position of the second limiting post 17 again. At this time, the bottom moving plate 101 is completely disengaged from one side of the shovel head 12. The limiting plate 16 is operated in the same way, so that the first limiting post 15 returns to the initial position. The U-shaped plate 13 fixedly connected to the bottom of the first limiting post 15 slides and engages with one side of the shovel head 12 again, so that the next inspection work can be carried out.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
