TECHNICAL FIELD

[0001] The utility model relates to soil sampling technical field, concretely is a soil sampling device for saline and alkaline land improvement. BACKGROUND

[0002] Saline and alkaline land improvement is an important agricultural technology, aiming to improve saline soil, alkaline soil and salinized land, improve its fertility, and create a suitable environment for crop growth. The improvement methods are various, mainly including engineering measures, agronomic measures, chemical measures and biological measures. Engineering measures such as establishing drainage system, open ditch salt drainage, and buried pipe salt drainage can effectively reduce soil salinity. Agronomic measures improve soil structure and fertility through deep plowing, land leveling, and application of organic fertilizer. Chemical measures often use desulfurized gypsum and other improvers to adjust soil pH. Biological measures focus on planting salt-tolerant crops and pasture, and improving soil properties through biological activities.

[0003] In the process of saline and alkaline land improvement, in order to ensure the quality of soil and the improvement effect, the staff often need to detect the soil carefully. In order to complete this task, they must carry the sampling shovel into every corner of the saline and alkaline land, and carry out soil sampling work. Since the area of saline and alkaline land is often very wide, sampling is often needed at many different positions to ensure the representativeness and accuracy of the sample. In this way, the labor intensity of the staff will be greatly increased, and since the sampling process completely depends on manual operation, the sampling speed is relatively slow.

DETAILED DESCRIPTION

[0020] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0021] As Figure 1 And Figure 2 The utility model provides a kind of technical scheme of soil sampling device for saline-alkali soil improvement, including crawler carrier 2, sealing cover plate 3 is rotatably installed on crawler carrier 2, movable gap 1 is set in the front end of crawler carrier 2, sampling mechanism 4 is fixedly installed in crawler carrier 2, storage mechanism 5 is installed in crawler carrier 2, by the cooperation of sampling mechanism 4 and storage mechanism 5, automatic sampling can be realized, and the labor intensity of staff is reduced.

[0022] As Figure 2 And Figure 3As shown in the drawings, the sampling mechanism 4 includes a mounting arm 401 fixedly installed in the crawler 2, a mounting shaft 404 rotatably installed on the mounting arm 401, a sampling shovel 402 and a worm gear 403 fixedly installed on the mounting shaft 404, a worm 405 rotatably installed on one side of the worm gear 403, a drive shaft 408 fixedly installed at the output end of the drive motor 409, a linkage shaft 407 provided between the drive shaft 408 and the worm 405, a first clutch 406 installed on the linkage shaft 407, and a retainer provided in the crawler 2, wherein the drive shaft 408 and the linkage shaft 407 are rotatably installed in the crawler 2 through the retainer, and the upper end of the linkage shaft 407 is fixedly installed on the worm 405.

[0023] Specifically, during the forward movement of the crawler 2, the sampling shovel 402 can effectively shovel the soil sample. Once the soil sample is successfully shoveled, the next operation is to ensure that the first clutch 406 is in the engaged state. When the first clutch 406 is in the engaged state, the drive motor 409 can start to work, which drives the linkage shaft 407 to rotate. The rotation of the linkage shaft 407 further drives the worm 405 to rotate, and the rotation of the worm 405 further drives the worm gear 403 to rotate. The rotation of the worm gear 403 is transmitted to the sampling shovel 402 on the mounting shaft 404, so that the sampling shovel 402 rotates. The rear end of the sampling shovel 402 rotates towards the direction of the storage box 502, and finally pours the sample in the sampling shovel 402 into the storage compartment in the storage box 502, thereby completing the whole process of automatic sampling.

[0024] As shown in the drawings, Figure 2 and Figure 4 The storage mechanism 5 includes an equipment base 501 fixedly installed in the crawler 2, a positioning shaft 504 rotatably installed at the middle position of the equipment base 501, a rotating seat 503 fixedly installed at the upper end of the positioning shaft 504, a transmission shaft 506 rotatably installed at the lower end of the positioning shaft 504, a second clutch 507 provided on the transmission shaft 506, a storage box 502 connected to the rotating seat 503, bevel gears 505 provided on the linkage shaft 407, the drive shaft 408, the positioning shaft 504 and the transmission shaft 506, and the bevel gears 505 meshed with each other, a bearing provided at the middle position of the equipment base 501, and the positioning shaft 504 rotatably installed on the equipment base 501 through the bearing.

[0025] Specifically, when the second clutch 507 is in the engaged state, the drive motor 409 can drive the transmission shaft 506 to rotate. The rotation of the transmission shaft 506 causes the rotation of the positioning shaft 504, which further drives the rotation of the rotating seat 503. The rotation of the rotating seat 503 further drives the rotation of the storage box 502, so that the empty storage compartment on the storage box 502 moves to the position below the sampling shovel 402, thereby facilitating the collection and storage of samples from different areas of the saline-alkali soil.

[0026] Working principle: when in use, the crawler 2 can be controlled to move on the saline-alkali soil, and the sampling shovel 402 can be lowered when the crawler 2 moves on the saline-alkali soil, with the tail end of the sampling shovel 402 facing the ground, so that the sampling shovel 402 can shovel the soil sample during the forward movement of the crawler 2, and after the soil sample is shoveled, the first clutch 406 can be controlled to be in the engaged state, and after the first clutch 406 is in the engaged state, the driving motor 409 can drive the linkage shaft 407 to rotate, and after the linkage shaft 407 rotates, it will drive the worm 405 to rotate, and after the worm 405 rotates, it will drive the worm gear 403 to rotate, and after the worm gear 403 rotates, it will drive the sampling shovel 402 on the mounting shaft 404 to rotate, so that the rear end of the sampling shovel 402 faces the storage box 502, and the sample in the sampling shovel 402 is poured into the storage compartment in the storage box 502, realizing automatic sampling. At the same time, the second clutch 507 can be controlled to be in the engaged state, and when the second clutch 507 is in the engaged state, the driving motor 409 can drive the transmission shaft 506 to rotate, and after the transmission shaft 506 rotates, it will drive the positioning shaft 504 to rotate, and after the positioning shaft 504 rotates, it will drive the rotary seat 503 to rotate, and after the rotary seat 503 rotates, it will drive the storage box 502 to rotate, so that the empty storage compartment on the storage box 502 moves to the lower side of the sampling shovel 402, facilitating the storage of the samples obtained from different parts of the saline-alkali soil.
