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.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Reference Figure 1-4 This utility model provides an agricultural soil research sampler, comprising:

[0027] A top plate 1 is provided, and several guide columns 2 are fixedly connected to the top plate 1. A bottom plate 3 is fixedly connected to the bottom end of the guide columns 2. A first through hole 4 is provided on the top plate 1. A moving plate 5 is slidably connected to the guide columns 2. A motor 6 is fixedly connected to the moving plate 5. A cylinder 7 is rotatably connected inside the moving plate 5. The motor 6 is connected to the cylinder 7 in a transmission connection. A fifth through hole is provided on the bottom plate 3. The cylinder 7 is slidably connected inside the fifth through hole. A drill bit 8 is detachably connected to the cylinder 7. Several sampling holes are provided on the side wall of the cylinder 7. A plug is detachably connected to the sampling holes. The plug extends out of the cylinder 7. Several support feet 9 are fixedly connected to the bottom plate 3.

[0028] The sampling assembly includes an inner column 10, which has several mounting slots 11. An electric telescopic rod 12 is fixedly connected to the mounting slot 11. A sampling box 13 is fixedly connected to the output end of the electric telescopic rod 12. The inner column 10 is detachably connected to the cylinder 7. The sampling box 13 is set to correspond to the sampling hole.

[0029] In this device, the moving plate 5 slides on the guide column 2, and the motor 6 drives the cylinder 7 to rotate. When the cylinder 7 rotates, the drill bit 8 drills into the soil. The cylinder 7 drills into the soil along with the drill bit 8, and the moving plate 5 also moves down. The plug is used to block the sampling hole to prevent soil from entering the sampling hole during the drilling process of the cylinder 7. Before the cylinder 7 enters the soil, the inner column 10 is placed inside the cylinder 7. When the cylinder 7 enters the predetermined depth, the plug is removed, and then the electric telescopic rod 12 is activated. The electric telescopic rod 12 extends, allowing the sampling box 13 to extend out of the sampling hole and insert into the soil, so that soil at different depths can be collected at one time. After the sampling box 13 has finished collecting, the electric telescopic rod 12 is retracted. The motor 6 is reversed to make the drill bit 8 and the cylinder 7 reverse and exit the soil. The inner column 10 is taken out, and the soil sample is taken out from the sampling box 13.

[0030] The design is further optimized by fixing a support plate 14 inside the cylinder 7. The support plate 14 has a rectangular insertion hole. An insertion rod 15 is fixedly connected to the inner column 10. The insertion rod 15 is rectangular and is inserted into the insertion hole. The inner column 10 extends out of the cylinder 7.

[0031] The inner column 10 is connected to the support plate 14 via the insert rod 15, which facilitates the installation and removal of the inner column 10.

[0032] Further optimization of the scheme: the plugging device includes an arc-shaped plate 16, on which several plugging blocks 17 are fixedly connected. The upper and lower edges of the sampling hole are inclined. The plugging blocks 17 are adapted to the sampling hole. The arc-shaped plate 16 extends out of the cylinder 7. A rubber base 25 is fixedly connected inside the cylinder 7. The arc-shaped plate 16 abuts against the rubber base 25.

[0033] The arc-shaped plate 16 fits easily against the inner wall of the cylinder 7. The block 17 is plugged into the sampling hole. The upper and lower edges of the sampling hole are inclined to facilitate the removal of the block 17. The rubber base 25 can hold the arc-shaped plate 16 in place to prevent the block 17 from falling out of the sampling hole during the drilling process of the cylinder 7. When it is necessary to remove the arc-shaped plate 16, it can be removed by force. The rubber base 25 has a certain elasticity and will not be damaged.

[0034] In a further optimized design, a top cover 18 is detachably connected to the cylinder 7. The top cover 18 has a second through hole and a third through hole. The second through hole is adapted to the arc plate 16, and the third through hole is adapted to the inner column 10.

[0035] The arc-shaped plate 16 enters the second through hole, and the inner column 10 enters the third through hole, thus fixing the arc-shaped plate 16 and the inner column 10 in place.

[0036] In a further optimized design, a first gear 19 is fixedly connected to the output end of the motor 6, and a gear ring 20 is fixedly connected to the cylinder 7, with the first gear 19 meshing with the gear ring 20.

[0037] Motor 6 drives the first gear 19 to rotate, and the first gear 19 drives the gear ring 20 to rotate.

[0038] In a further optimized design, a fourth through hole is provided on the movable plate 5, and the cylinder 7 is located inside the fourth through hole. A bearing 21 is fixedly connected inside the fourth through hole, and the cylinder 7 and the movable plate 5 are rotatably connected through the bearing 21.

[0039] The cylinder 7 is rotatably connected to the movable plate 5 via the bearing 21, making the cylinder 7 more flexible.

[0040] The scheme is further optimized. A guide tube 22 is fixedly connected inside the fifth through hole. The cylinder 7 is slidably set inside the guide tube 22. Several through holes are opened on the moving plate 5. The guide rod 2 passes through the through holes and is slidably set inside the through holes.

[0041] The guide tube 22 allows the cylinder 7 to move straight up and down, and through the through hole, the moving plate 5 slides on the guide column 2.

[0042] The design is further optimized by fixing several baffles 23 to the support leg 9 and a handle 24 to the top plate 1.

[0043] The baffle 23 prevents the support leg 9 from completely entering the soil, and the handle 24 facilitates the handling of this device.

[0044] The method of using this device is as follows: Move the device to the designated location. Before starting the motor 6, ensure that the insertion rod 15 of the inner cylinder 10 is inserted into the insertion hole and that the blocking block 17 on the arc-shaped plate 16 is located in the sampling hole. Then, place the top cover 18 on the cylinder 7 and start the motor 6. The motor 6 drives the first gear 19 to rotate, which in turn drives the gear ring 20 to rotate. The gear ring 20 then drives the cylinder 7 to rotate. As the cylinder 7 rotates, it drills into the soil along with the drill bit 8. Once the cylinder 7 has reached the predetermined depth, remove the top cover 18 and the arc-shaped plate 16, allowing the blocking block 17 to be removed from the sampling hole. Then, start the electric telescopic rod 12. The electric telescopic rod 12 extends, allowing the sampling box 13 to extend out of the sampling hole and enter the soil, thus enabling the collection of soil samples from different depths at once. After the sampling box 13 has completed its collection, retract the electric telescopic rod 12. Reverse the motor 6 to reverse the drill bit 8 and the cylinder 7, causing them to exit the soil. Remove the inner cylinder 10 and extract the soil sample from the sampling box 13.
