The drill rod 20 movably penetrates through the bracket 10, and the driving member 30 is arranged on the bracket 10, and the driving member 30 drives the prism rod 23 to rotate. Among them, the driving member 30 is used to drive the threaded drill bit 21 to drill the drill rod 20 into the soil, and the soil enters the hollow rod body 22 through the hollow drill bit 21. The sampling amount is large, and multiple layers of soil can be taken out completely. It is also convenient to replace different drill bits 21, rod bodies 22 and prism rods 23 according to the sampling depth, and the versatility is stronger.

[0037] Please refer to Figures 1 - 4 , the bracket 10 includes a sleeve 11 and legs 12. The legs 12 are hinged to the sleeve 11, and a disc 13 is hinged to the lower end of the legs 12. The legs 12 and the sleeve 11 form a tripod structure. A connecting rod 16 is also hinged to each leg 12, and all the connecting rods 16 are hinged to a ring plate 15. A nut 17 is screwed on the sleeve 11, and the nut 17 is rotatably connected to the ring plate 15. By rotating the nut 17, the legs 12 can be retracted and extended for driving into the soil to increase the support stability. A disc is provided at the lower end of the legs 12 for stepping on with the foot.

[0038] Please refer to Figures 1 - 4 , the upper end of the sleeve 11 is fixedly connected with a mounting plate 14, and the driving member 30 is arranged on the mounting plate 14. The mounting plate 14 is used for mounting the driving member 30.

[0039] Please refer to Figures 1 - 4 , a ring plate 15 is sleeved on the sleeve 11, and a connecting rod 16 is hinged to the leg 12, and all the connecting rods 16 are hinged to the ring plate 15. By moving the ring plate 15 up and down, the legs 12 can be pulled to retract and extend through the connecting rods 16, achieving the effects of expansion and folding.

[0040] Please refer to Figures 1 - 4 , a nut 17 is rotatably connected to the ring plate 15, and the nut 17 is threadedly connected to the sleeve 11. By rotating the nut 17, the axial position of the ring plate 15 on the sleeve can be adjusted to realize the expansion and folding of the legs 12 and lock the current state.

[0041] Please refer to Figures 1 - 4, the driving member 30 includes a worm gear 31 which is rotatably connected to the mounting plate 14. A rib groove is axially formed through the center of the worm gear 31, and the rib rod 23 movably passes through the rib groove. When the worm gear 31 rotates, it can drive the rib rod 23 to rotate. When the drill bit 21 drills into the soil, it can drive the entire drill rod 20 to move downward and maintain a circumferential fixed connection with the worm gear 31.

[0042] Please refer to Figures 1 - 4 , the driving member 30 further includes a worm 32 and a motor 33. The worm 32 meshes with the worm gear 31. The motor 33 is mounted on the mounting plate 14, and the output end of the motor 33 is fixedly connected to the worm 32. The motor 33 drives the worm 32 to rotate, and drives the worm gear 31 through the worm 32, which can increase the torque and the ability to drill into the ground.

[0043] Please refer to Figures 1 - 5 , a positioning pin 24 and a pin hole adapted to the positioning pin 24 are provided on the mating surface of the rod body 22. The positioning pins 24 are evenly arranged along the axial direction of the rod body 22. When the two parts of the rod body 22 are closed, they form a round rod. The positioning pin 24 is used to ensure accurate positioning during closing, and can also increase the connection strength of the two parts, facilitating the transmission of torque.

[0044] Please refer to Figures 1 - 4 , the lower end of the rod body 22 is screwed to the drill bit 21, and a set screw A25 is screwed through the rod body 22 and the drill bit 21. After the rod body 22 is closed, the drill bit 21 is screwed on to facilitate fixing the rod body 22 into one body, and then the set screw A25 is screwed in to increase the circumferential fixing force so that loosening will not occur during forward and reverse rotations.

[0045] Please refer to Figures 1 - 5 , the upper end of the rod body 22 is screwed to the rib rod 23, and a set screw B26 is screwed through the rib rod 23 and the rod body 22. After the rod body 22 is closed, the rib rod 23 is screwed on to facilitate fixing the rod body 22 into one body, and then the set screw B26 is screwed in to increase the circumferential fixing force so that loosening will not occur during forward and reverse rotations.

[0046] The working principle of the soil sampler for agricultural soil detection is as follows: Unfold the bracket 10 and place it on the ground. After the rod body 22 is folded, screw the drill bit 21 onto one end of the rod body 22 and the prism rod 23 onto the other end. Then, screw in the set screw A 25 and the set screw B 26 respectively to fix the rod body 22 into one body to increase the circumferential fixing force so that loosening will not occur during forward and reverse rotation. Insert the prism rod 23 onto the worm gear 31, and the motor 33 drives the drill rod 20 to rotate through the meshing of the worm 32 and the worm gear 31. If the soil is hard, strike the upper end of the prism rod 23 with a hammer to help the drill bit 21 penetrate. During the penetration of the drill bit 21, the soil enters from the center of the drill bit 21 and then into the rod body 22. When the drill rod 20 reaches the bottom, the motor 33 rotates in reverse to pull out the drill rod 20, and then the rod body 22 is disassembled and separated. The positioning pin 24 serves as a scale, enabling the soil stratification to be visually observed and facilitating the extraction of samples. In summary, the driving member 30 is used to drive the threaded drill bit 21 to penetrate the drill rod 20 into the soil, and the soil enters the hollow rod body 22 through the hollow drill bit 21. The sampling volume is large, multiple layers of soil can be completely extracted, and it is also convenient to replace different drill bits 21, rod bodies 22, and prism rods 23 according to the sampling depth, with stronger versatility.
