[0016] The following further clarifies the present utility model in conjunction with the drawings and specific embodiments. These embodiments are implemented on the premise of the technical solution of the present utility model. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model.

[0017] Such as Figure 1 and Figure 2As shown in the figure, an embodiment of the utility model provides a soil detection sampling device, which includes a base 1. The cross-section of the base 1 is preferably circular. The interior of the base 1 is hollow, and an opening is provided at the lower end of the base 1. A mounting opening is provided in the middle of the upper side of the base 1, and a threaded sleeve 2 is fixed outside the mounting opening. The threaded sleeve 2 is preferably fixed by a plurality of bolts. An internal thread structure is provided in the middle of the threaded sleeve 2, and an external thread structure is provided on the outer side of the middle of the sampling rod 3, so that the sampling rod 3 is threadedly connected to the threaded sleeve 2. A first through hole 31 is provided in the middle of the sampling rod 3, and a plurality of soil-breaking teeth 32 are provided at the lower end of the sampling rod 3 to facilitate drilling into the soil. The upper end of the sampling rod 3 is fixedly connected to the rotor of the motor 4. The motor 4 is connected to the control box 18, and the control box 18 is preferably arranged on one side of the base 1. The control box 18 is provided with a storage battery, a control board, etc. The storage battery is connected to the control board to provide the power required for operation, and the control board is used to control the operation of the motor 4 according to the control instruction. The above control instruction can be issued by the control button provided on the control box or the remote control terminal wirelessly connected to the control board. The stator of the motor 4 is fixed on the upper side of the mounting plate 5, and an avoidance hole for the rotor to pass through is provided in the middle of the mounting plate 5. A sliding rod 6 is fixed on the upper side of the base 1, and the mounting plate 5 is slidably connected to the sliding rod 6. When the motor 4 is controlled to rotate, while driving the sampling rod 3 to rotate, it can also make the sampling rod 3, the motor 4 and the mounting plate 5 move up and down together. The moving direction is determined by the rotation direction of the motor 4. When the sampling rod 3 rotates and moves downward, the lower end of the sampling rod 3 can be drilled into the soil. When the sampling rod 3 rotates and moves upward, the lower end of the sampling rod 3 is pulled out of the soil. During this period, the soil in the first through hole 31 will not easily fall out of the first through hole 31 under the action of friction. A second through hole 41 is provided in the middle of the rotor, and the first through hole 31 is communicated with the second through hole 41. A pressing plate 7 is slidably connected in the first through hole 31. The upper end of the pressing plate 7 is fixedly connected to a pressing rod 8, and the pressing rod 8 is slidably connected in the second through hole 41. When the rotor and the sampling rod 3 rotate, they will not be affected by the pressing plate 7 and the pressing rod 8. The upper end of the pressing rod 8 is arranged on the upper side of the rotor, and a top block 9 is fixedly connected to the upper end of the pressing rod 8. A spring 10 is sleeved outside the pressing rod 8 between the top block 9 and the stator. Under the action of the spring 10, the pressing plate 7 can be kept at a certain distance from the lower end of the sampling rod 3.

[0018] Preferably, there are two sliding rods 6 in the embodiment of the utility model, and the two sliding rods 6 are oppositely arranged along the center of the mounting plate 5. During soil sampling, the pressing plate 7 can press the soil entering the first through hole 31 by pressing down the top block 9, so that the through hole in the first through hole 31 is in a pressed state, thereby preventing the soil in the first through hole 31 from falling during the upward movement of the sampling rod 3. After sampling is completed, the sampling rod 3 is rotated upward by controlling the motor 4, and then the soil in the first through hole 31 can be pressed out by manually pressing the top block 9. In order to facilitate the automatic pressing out of the soil in the first through hole 31, a top plate 11 is fixedly connected to the upper ends of the two sliding rods 6, and the top plate 11 is arranged above the top block 9. After the sampling rod 3 is controlled to move upward to a set distance, the top block 9 can be abutted against the lower side of the top plate 11, and by continuously controlling the upward movement of the sampling rod 3, the top block 9 can drive the pressing rod 8 and the pressing plate 7 to move relative to the sampling rod 3, thereby automatically pressing out the soil in the first through hole 31.

[0019] A sliding sleeve 12 is fixed on the mounting plate 5, and the sliding rod 6 is slidably connected with the sliding sleeve 12. Specifically, the sliding sleeve 12 includes a metal outer tube and a bushing fixedly arranged inside the metal outer tube, and the sliding rod 6 is slidably connected inside the bushing. The above-mentioned sliding rod 6 is preferably made of a stainless steel sliding rod, and the bushing is preferably a polytetrafluoroethylene bushing with a small friction coefficient. The above-mentioned pressing plate 7 and pressing rod 8 are also preferably made of polytetrafluoroethylene material.

[0020] In order to prevent the base 1 from sliding easily, a plurality of anti-slip teeth 13 are provided at the lower end of the base 1. The base 1 is preferably made of steel to ensure that the overall equipment has a certain mass. When the equipment is placed at the sampling site, if the soil at the site is relatively soft, the anti-slip teeth 13 can automatically insert into the soil. If the soil at the site is relatively hard, the anti-slip teeth 13 can be inserted into the soil by means of manual stepping on and pressing, which is beneficial to the subsequent stable sampling work. In addition, in order to facilitate the loss of the anti-slip teeth 13 during placement and transportation, the equipment is also preferably equipped with a bottom plate, and an avoidance groove for the anti-slip teeth 13 to insert can be provided on the bottom plate.

[0021] In order to facilitate the extraction of the sampled soil, a sampling port 14 is preferably provided on one side of the base 1. After the sampling rod 3 is controlled to move to a certain height, a sampling container can be placed through the sampling port 14 under the sampling rod 3, and then by controlling the sampling rod 3 to continue moving upward, the sampled soil can be pressed into the sampling container.

[0022] In order to facilitate the movement of the equipment, a handle 15 is preferably provided on both sides of the upper end of the base 1 respectively. The equipment can be lifted by the handle 15.

[0023] In order to facilitate the fixation of the rotor of the motor 4 to the upper end of the sampling rod 3, a first flange 16 is fixed to the lower end of the rotor of the motor 4, a second flange 17 is fixed to the upper end of the sampling rod 3, and the first flange 16 and the second flange 17 are fixedly connected by a plurality of bolts.

[0024] The above are only the preferred embodiments of the present utility model. It should be pointed out that for those of ordinary skill in the art, the parts not specifically described belong to the prior art or common general knowledge. Without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
