DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Example 1: Reference Figure 1-Figure 6 A deep soil sampling device for agricultural and forestry planning includes: a base 1, and also includes: a frame 202, which is rotatably set on the base 1; a plurality of drill rods 4, which are set in the frame 202, and two adjacent drill rods 4 are detachably connected; a driving component for driving the drill rods 4 to move downward; a sampling component, which is set at the lower end of the drill rod 4, and the sampling component is used to sample deep soil; a controller 107, which is fixedly set on the base 1.

[0030] A plurality of universal wheels 101 are fixedly connected to the lower end of the base 1 .

[0031] A plurality of connection ears 102 are fixedly connected to the base 1 , and ground nails 103 are arranged on the connection ears 102 .

[0032] The driving assembly includes a first electric telescopic rod 203 symmetrically fixedly arranged on the frame 202 , the telescopic end of the first electric telescopic rod 203 is fixedly connected to a connecting plate 204 , and a connecting assembly is arranged between the connecting plate 204 and the drill rod 4 .

[0033] A rotating disk 2 is rotatably provided on the base 1, and the rotating disk 2 is fixedly connected to the frame 202. A connecting arm 104 is fixedly connected to the base 1, and a first motor 105 is fixedly connected to the connecting arm 104. The output end of the first motor 105 is fixedly connected to a first gear 106, and the upper end of the rotating disk 2 is fixedly connected to a first gear ring 201, and the first gear 106 is meshed with the first gear ring 201.

[0034] The sampling assembly includes multiple connecting rods 402, two adjacent connecting rods 402 are threadedly connected, and the lower end of the connecting rod 402 at the lowest end is provided with a drill bit 403 matching the drill rod 4, the drill rod 4 is provided with a first spiral piece 401, and the outer side of the drill bit 403 is fixedly connected with a second spiral piece 404.

[0035] The connecting assembly includes a second electric telescopic rod 205 fixedly connected to the connecting plate 204, a first through hole 405 is symmetrically opened on the drill rod 4, and a second through hole 406 is provided on the connecting rod 402. The first through hole 405 and the second through hole 406 both match the output end of the second electric telescopic rod 205.

[0036] When the deep soil sampling device is in operation, the device is first moved to a sampling position by means of the universal wheel 101 at the lower end of the base 1, and then the ground spike 103 on the connecting ear 102 is inserted into the ground.

[0037] The controller 107 starts the first motor 105, and the first motor 105 drives the first gear 106 to rotate. The first gear 106 meshes with the first gear ring 201 on the rotating disk 2, so that the rotating disk 2 and the frame 202 fixed thereon rotate, thereby driving the drill rod 4 set in the frame 202 to rotate. At the same time, the telescopic end of the first electric telescopic rod 203 pushes the connecting plate 204, and the connecting plate 204 drives the drill rod 4 to move downward through the connecting assembly. The first spiral piece 401 on the drill rod 4 and the second spiral piece 404 outside the drill bit 403 help the drill rod 4 to drill into the soil smoothly.

[0038] When sampling of deeper soil layers is required, multiple drill rods 4 can be connected in sequence through a connecting assembly to increase the drilling depth.

[0039] When the lower end of the drill rod 4 moves to the depth to be sampled, the controller 107 controls the second electric telescopic rod 205 to retract a certain distance, so that the output end of the second electric telescopic rod 205 slides out of the second through hole 406, and then the drill bit 403 is controlled to move downward through the connecting rod 402, and the drilled soil enters the drill rod 4 through the second spiral sheet 404, and then the connecting rod 402 is pulled to reset, so that the deep soil can be sampled accurately to prevent the soil at other depths from mixing with the soil at the depth to be sampled.

[0040] The sampling of soil at different depths is achieved through multiple detachable drill rods 4. Compared with traditional deep soil sampling equipment, the drill rods 4 can be disassembled when not in use, which greatly reduces the storage volume of the device, facilitates transportation and storage, and solves the problem of large volume of current deep soil sampling equipment.

[0041] Since the drill rods 4 are detachably connected and the number of drill rods 4 can be increased or decreased as needed, the device can adapt to soil sampling needs at different depths. It has strong versatility and flexibility and can be widely used in fields such as agriculture and forestry planning to provide accurate samples for soil analysis and other tasks.

[0045] When sampling, the uppermost drill rod 4 is first pressed down to a specified position by extending the first electric telescopic rod 203, and when the gear rod 407 moves to correspond to the second gear 304, the third electric telescopic rod 302 is controlled to extend by the controller 107, and the third electric telescopic rod 302 drives the moving frame 301 to approach the gear rod 407, so that the second gear 304 is meshed with the gear rod 407, and the second gear 304 is driven to rotate by the second motor 305 and the third gear 306, and the second gear 304 is moved to the left and right sides of the gear rod 407. The gear rod 407 is driven to rotate, and the handle 408 is manually pressed down to make the drill bit 403 drill downward, and the drilled soil moves upward through the second spiral piece 404, and then enters the drill rod 4, and finally the second motor 305 is reversed, and the handle 408 is pulled upward to make the drill bit 403 block the port of the drill rod 4, and the second electric telescopic rod 205 is controlled to extend, so that the telescopic end of the second electric telescopic rod 205 is inserted into the second through hole 406, so that the soil at the sampling depth can be accurately sampled.
