Description

Technical Field

[0001] The utility model belongs to the technical field of soil detection, in particular to a soil sampling device. Background Art

[0002] Soil sample collection refers to the process of taking a representative part of the soil from the field, field, culture or cultivation unit. The soil sample obtained is properly processed and prepared into an analytical sample. The test sample taken for the final analysis is only a few grams or even a few tenths of a gram, and the analysis result should represent the entire soil. Therefore, a representative average sample must be taken correctly, otherwise even if the analysis process is accurate, it will be useless and may even lead to wrong conclusions, causing unnecessary losses to production or scientific research. Sampling is generally divided into single-point samples and mixed samples. Single-point samples mean that only one point is sampled for each sample, which can be divided into disturbed samples, undisturbed samples and profile samples.

[0003] Chinese patent CN218725427U discloses a soil remediation and improvement sampling device, including a sampling box, the top of which is fixedly connected to one end of the top plate, and a driving motor is fixedly installed on the other end of the top plate. The motor shaft of the driving motor passes through the top plate and is detachably connected to the sampling tube. The sampling tube includes multiple detachably connected tube sections, the bottom surface of the top plate is connected to the support column, the support column is inserted into the groove of the fixed frame, one side of the fixed frame is detachably connected to the side wall of the sampling box through a plug-in, and a through hole is opened in the center of the fixed frame for accommodating the sampling tube to pass through. The soil remediation and improvement sampling device drives the sampling tube up and down by a motor to sample the soil. It is not only simple to operate, but also time-saving and labor-saving; by setting the sampling tube as a multi-section detachable structure, it is not only convenient to pour out the soil after sampling, but also can be used for separate detection of soil at different depths, and then before spraying the improver on the soil, the soil at that point can be plowed in a targeted depth.

[0004] The above-mentioned traditional soil sampling device still uses manual discharging when discharging is required, but the manual operation of discharging is not perfect during the operation, and the operation is time-consuming and labor-intensive.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0027] Reference Figure 1-6As shown, a soil sampling device includes a support table 1 and two groups of vertical plates 2 fixed to the bottom of the support table 1. Both the front and rear ends of the two groups of vertical plates 2 are equipped with moving wheels 319. The setting of the moving wheels 319 can facilitate the movement of the support table 1 and the two groups of vertical plates 2, which is more stable to use and improves the soil sampling range of the equipment. The bottom of the support table 1 is connected to a sampling barrel 311 through a driving mechanism. The setting of the sampling barrel 311 can sample the soil, and the staff can use the sampled soil for testing and use, achieving a better use effect. A sampling chamber 321 is provided inside the sampling barrel 311, a vertical groove 323 is provided on the side wall of the sampling barrel 311, an arc groove 322 corresponding to the vertical groove 323 is provided at the top of the sampling barrel 311, and a plurality of puncture protrusions 320 are fixed at the bottom of the sampling barrel 311, and the cross section of the puncture protrusion 320 is triangular. The puncture protrusion 320 can achieve a good puncture effect. The sampling barrel 311 and the puncture protrusion 320 are pressed down under the driving mechanism, and the puncture protrusion 320 can puncture the soil and store the soil inside the sampling chamber 321, so as to achieve a fast sampling effect. A guide hole 317 is provided inside the support table 1, and a connecting plate 315 is fixed on the outer wall of the threaded sleeve 312, and a guide rod 316 penetrating the guide hole 317 is fixed on the top of the connecting plate 315. The guide rod 316 and the guide hole 317 can ensure the stable up and down movement of the threaded sleeve 312, and achieve good stability. A baffle 318 is fixed on the top of the guide rod 316. The diameter of the baffle 318 is larger than the diameter of the guide hole 317. The baffle 318 has a good protective effect, ensuring that the guide rod 316 will not be completely separated from the inside of the guide hole 317. The driving mechanism includes a threaded sleeve 312, a first motor 313 and an adjusting screw 314. The first motor 313 is installed on the top of the support table 1 and the output end is connected to the adjusting screw 314. The outer wall of the adjusting screw 314 is threadedly connected to the threaded sleeve 312 fixed to the top of the sampling tube 311. The first motor 313 is turned on to drive the adjusting screw 314 to rotate, and the threaded sleeve 312 and the sampling tube 311 are driven to move vertically back and forth under the action of the thread, so as to achieve the effect of soil sampling and discharging.

[0028] The sampling device also includes a scraper 411 that slides horizontally relative to the outer wall of the vertical plate 2 and a movable rod 412 fixed to the scraper 411 away from the side of the sampling tube 311. When the sampling tube 311 takes the material and rises, the movable rod 412 is moved to drive the scraper 411 to be inserted into the arc groove 322. When the sampling tube 311 rises, the movable rod 412 can slide along the inner wall of the vertical groove 323. The inner wall of the vertical plate 2 is fixed with an insertion rod 413, and the movable rod 412 is sleeved on the outer wall of the insertion rod 413 to ensure that the movable rod 412 moves stably enough. A fixed plate 416 is fixed to the side wall of the vertical plate 2, and a second motor 417 is installed on the outer wall of the fixed plate 416. A rotating rod 418 is connected to the output end of the second motor 417. A rotating gear 419 is fixed to the end of the rotating rod 418 away from the second motor 417. A rack plate 414 meshing with the rotating gear 419 is fixed to the top of the movable rod 412. After the second motor 417 is turned on, the rotating rod 418 and the rotating gear 419 are driven to rotate, and the rack plate 414, the movable rod 412 and the scraper 411 are driven to move stably to achieve an automated driving effect. A wear-resistant layer 415 is fixed to the outer wall of the scraper 411. The wear-resistant layer 415 is made of rubber and has a good wear-resistant effect. After the wear-resistant layer 415 is embedded in the arc groove 322, it can fit tightly to the inner wall of the sampling chamber 321, achieving a comprehensive scraping effect, avoiding soil residue, and ensuring that the sampling and detection effect will not be affected when used next time.

[0029] Working principle: When sampling is required, the first motor 313 is turned on to drive the adjusting screw 314 to rotate, and the threaded sleeve 312 and the sampling barrel 311 are driven to move downward under the action of the thread, and the piercing protrusion 320 at the bottom of the sampling barrel 311 can be embedded in the soil, and the guide rod 316 can slide on the inner wall of the guide hole 317, and then the threaded sleeve 312 is turned on again to drive the adjusting screw 314 to reverse, and similarly, the sampling barrel 311 can be driven to move the collected soil upward;

[0030] Then, the second motor 417 is turned on to drive the rotating rod 418 and the rotating gear 419 to rotate. The rotating gear 419 drives the rack plate 414, the movable rod 412 and the scraper 411 to be inserted into the arc groove 322. When the sampling tube 311 continues to move upward, the scraper 411 scrapes the inner wall of the wear-resistant layer 415 to completely scrape off the soil inside the sampling chamber 321, thereby achieving a fast discharging effect.
