Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-5 One embodiment provided by this utility model:

[0025] A soil sampler for soil testing, comprising:

[0026] The device includes a pipe frame 1, with a connecting pipe 11 and a foot pedal 15 mounted on its surface. A soil sampling drill bit 12 is fixedly connected to the surface of the pipe frame 1, and a pusher rod 13 is movably connected to the inner surface of the pipe frame 1. A rubber sleeve 14 is fitted onto the surface of the connecting pipe 11. The surface of the pipe frame 1 is T-shaped. When using the sampler, first align the soil sampling drill bit 12 with the area of ​​soil to be sampled, press the connecting pipe 11 against the ground, and simultaneously step on the foot pedal 15 to make the soil sampling drill bit 12 enter the soil more smoothly. The pusher rod 13 moves along the inner side of the pipe frame 1 after being squeezed by the soil. Then, rotate the connecting pipe 11 around the soil sampling drill bit 12 to extract the soil from the ground into the soil sampling drill bit 12. Finally, push the pusher rod 13 to push the soil out of the soil sampling drill bit 12.

[0027] The rotating mechanism includes a fixed block 2, which is fixedly connected to the surface of the tube frame 1. A movable block 21 and a mounting sleeve 25 are fixedly connected to the surface of the connecting tube 11. A rotating hole 22 is opened on the surface of the fixed block 2. A rotating block 23 is fixedly connected to the surface of the movable block 21. A threaded tube 24 is movably connected to the surface of the tube frame 1. The outer sides of the fixed block 2 and the movable block 21 are arc-shaped and will not obstruct the normal movement of the threaded tube 24 on the surface of the tube frame 1 and the connecting tube 11. When the sampler is in use, the threaded tube 24 covers the surface of the fixed block 2 and the movable block 21. At this time, one end of the threaded tube 24 is sleeved on the surface of the tube frame 1, while the other end is connected to the mounting sleeve 25 by threads and abuts against its inner side.

[0028] Furthermore, there are two sets of fixed blocks 2, which are installed on both sides of the pipe rack 1. Each set of fixed blocks 2 consists of two blocks. Each set of fixed blocks 2 is installed on both sides of the movable block 21. The movable block 21 is movably connected to the surface of the fixed block 2. With the connection between the fixed block 2 and the movable block 21, the connection effect between the pipe rack 1 and the two sets of connecting pipes 11 can be achieved.

[0029] Furthermore, the diameter of the rotating hole 22 is the same as the diameter of the rotating block 23. Two sets of rotating blocks 23 are provided, and the two sets of rotating blocks 23 are installed on both sides of the movable block 21. The rotating blocks 23 are rotatably connected to the surface of the rotating hole 22. The threaded tube 24 is threadedly connected to the inner surface of the mounting sleeve 25. With the connection of the rotating hole 22 and the rotating block 23, the connecting tube 11 and the rubber sleeve 14 can rotate around the rotating block 23 as the center, and the rotating hole 22 and the rotating block 23 perform damped rotation. The inner diameter of the threaded tube 24 is the same as the outer diameter of the connecting tube 11.

[0030] Furthermore, the surface of the foot pedal 15 is provided with a connecting mechanism, which includes a connecting groove 3. The connecting groove 3 is opened on the surface of the foot pedal 15. A first side plate 31 is fixedly connected to one side of the foot pedal 15, and a second side plate 32 is fixedly connected to the other side of the foot pedal 15. A connecting hole 33 is opened on the surface of the second side plate 32. A limit plate 34 is fixedly connected to the surface of the first side plate 31. A bolt 35 is inserted into the surface of the connecting hole 33. A nut 36 is installed on the surface of the bolt 35. The foot pedal 15 is engaged with the surface of the tube frame 1 through the connecting groove 3 to realize the installation of the foot pedal 15.

[0031] Furthermore, the dimensions of the first side plate 31 and the second side plate 32 are the same. Two sets of connecting holes 33 are provided. One set of connecting holes 33 is opened on the surface of the first side plate 31, and the other set of connecting holes 33 is opened on the surface of the second side plate 32. The first side plate 31 and the second side plate 32 are symmetrically distributed on both sides of the connecting groove 3. The bolts 35 and nuts 36 can be installed through the first side plate 31 and the second side plate 32. Under the action of the connecting holes 33, the bolts 35 can be inserted into them and the installation effect can be achieved.

[0032] Furthermore, the surface of the limiting plate 34 is "V" shaped, and there are two sets of limiting plates 34. The two sets of limiting plates 34 are installed on both sides of the first side plate 31. When the bolt 35 is installed, the two sets of limiting plates 34 are engaged on both sides to limit the rotation of the bolt 35, thereby avoiding the situation where the bolt 35 is rotated together when the worker rotates the nut 36, causing the tightening difficulty.

[0033] Furthermore, the bolt 35 passes through the connecting hole 33 and is connected to the surface of the first side plate 31 and the second side plate 32. One end of the bolt 35 is engaged with the inner surface of the limiting plate 34, and the other end of the bolt 35 is threaded to the inner surface of the nut 36. The nut 36 abuts against the surface of the second side plate 32. With the connection of the bolt 35 and the nut 36, the first side plate 31 and the second side plate 32 can be brought closer to each other, and the connection between the foot pedal 15 and the tube frame 1 is more firmly engaged.

[0034] Working principle: When using the soil sampler, first move the connecting tube 11 and the rubber sleeve 14 together so that they rotate around the rotating block 23 as the center, so that the movable block 21 moves on the surface of the fixed block 2, while the rotating block 23 rotates in the rotating hole 22. When the threaded tube 24 and the connecting tube 11 are on the same straight line, move the threaded tube 24 towards the connecting tube 11 so that it covers the connection between the fixed block 2 and the movable block 21. Then rotate the threaded tube 24 so that it is threadedly connected to the inside of the mounting sleeve 25 and abuts against its surface, thereby achieving the limiting effect on the unfolded state of the connecting tube 11.

[0035] When replacing the foot pedal 15 due to damage from being stepped on, first bend the connection between the foot pedal 15 and the pipe rack 1 so that it is engaged with the surface of the pipe rack 1 through the connecting groove 3. Adjust the position of the foot pedal 15 according to the required movement. Once the position is determined, insert the bolt 35 from the first side plate 31 into the connecting hole 33 and through the first side plate 31 and the second side plate 32. The bolt 35 is then engaged with the inner side of the two sets of limiting plates 34. Then rotate the nut 36 so that it is threaded onto the bolt 35. After tightening the nut 36, make it abut against the surface of the second side plate 32, thereby fixing the foot pedal 15 to the pipe rack 1.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
