Description

Technical Field

[0001] The invention relates to the technical field of sampling devices, and in particular to a soil plate integral sampling device. Background Art

[0002] Soil sampling refers to the method of collecting soil samples, including the layout of the samples and sampling techniques. The actual sampling work of the soil is generally completed using a soil sampling device, and there are multiple types of sampling devices to meet different sampling needs.

[0003] In environmental monitoring, the metal element content in the soil is an important detection indicator, especially near water sources such as rivers and canals. The soil near the water source can be tested to assist in judging whether the water source meets the standard. However, most of the existing sampling devices use metal drill rods to drill under pressure, which causes the side of the sample taken out from the bottom to come into direct contact with the metal side wall. Therefore, after the sample is taken out, the outside of the sample needs to be scraped off, resulting in the soil sample being more dispersed and not analyzed as a whole. This results in the sample being less representative, affecting subsequent analysis work. Summary of the invention

DETAILED DESCRIPTION

[0026] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0027] See also Figures 1 to 9The embodiment of the present invention discloses a soil plate integral sampling device, which mainly includes a sampling rod body 1. A driving device is connected to the top of the sampling rod body 1. The driving device is responsible for providing necessary power for the sampling process. Whether it is manually driven or electrically driven, as long as the sampling rod body 1 can be rotated and pressed down, it will be fine. In this embodiment, the entire block of soil near the water source is sampled, and the texture is relatively loose. Therefore, the driving device can be manually driven, which can realize single-person operation and improve convenience.

[0028] A plurality of drilling blades 102 are spirally arranged on the side wall of the sampling rod body 1. These blades 102 can help to better cut into the soil during the sampling process and improve the sampling efficiency. A sampling tube 3 is arranged inside the sampling rod body 1. A certain interval is maintained between the sampling tube 3 and the sampling rod body 1. The sampling tube 3 is made of plastic. When extracting samples, the samples are only the part inside the sampling tube 3. Therefore, when the sampling rod body 1 moves downward and the soil enters the inside, the side wall of the sampling tube 3 will peel off the part of the sample side that contacts the metal sampling rod body 1, and the peeled part will enter the interval between the sampling tube 3 and the sampling rod body 1, reducing the direct contact between the soil and the metal parts during the sampling process, thereby avoiding sample contamination, and also eliminating the step of manually scraping the sample surface, so that the integrity of the sample is guaranteed and the sampling effect is improved.

[0029] A drill bit 101 is provided at the bottom of the sampling rod body 1. The drill bit 101 can be manually controlled to open and close. When in use, the sampling depth can be manually controlled. According to different sampling requirements, the opening and closing position of the drill bit 101 is controlled, eliminating the tedious steps of manual excavation. When excavating and sampling, the drill bit 101 is closed, and when the sampling rod body 1 drills downward, the depth of drilling downward is displayed according to the scale line on the side wall. After reaching the sampling depth, the drill bit 101 is opened by the control device, and the drill rod body continues to rotate. The soil sample will enter the sampling tube 3, which can more accurately control the entry of the soil, ensure the integrity of the sample, greatly reduce the interference of impurities in the sample, and improve the sampling effect.

[0030] The driving device includes a connecting block 202 arranged on the upper part of the sampling rod body 1. The connecting block 202 is connected to the sampling tube 3 by bolts or threads, and is locked by the hexagon socket bolts on the side to ensure the stability of the connection between the connecting block 202 and the sampling tube 3. The stability of the forward and reverse rotation of the sampling rod body 1 can be achieved. The middle position of the connecting block 202 is hollow, which is convenient for operating the sample storage device inside the sampling tube 3, providing an operating space for easy use. A power box 2 is arranged on the upper part of the connecting block 202. A main gear 203 connected to the connecting block 202 is arranged inside the power box 2. A driving gear 204 is on the side of the main gear 203. The driving gear 204 is connected to a hand-cranked crank 201. When in use, the operator stabilizes the power box 2 with one hand and drives the entire sampling device to rotate forward and reverse by shaking the crank 201 with the other hand.

[0031] A sample storage device is also provided inside the sampling tube 3, and the sample storage device comprises a sample storage cylinder 301 provided at the lower part of the sampling tube 3, a card slot is provided at the upper part of the sample storage cylinder 301, a card slot is provided on the inner wall of the sampling tube 3, and a card slot is provided for the card slot. The bottom of the sample storage cylinder 301 slightly protrudes from the bottom of the sampling rod body 1, and a working rod 302 is provided at the center position of the sample storage cylinder 301, and a connecting column 303 is provided at the top of the working rod 302. When in use, an operating rod 205 is inserted from the middle position of the connecting block 202, and the end is connected with the connecting column 303. The operating rod 205 acts on the working rod 302 to make the working rod 302 rotate, and the working rod 302 rotates. The rod 302 is rotatably arranged inside the sample storage cylinder 301 through a connecting rod, and a sealing tube 304 is arranged at the upper and lower parts of the side wall of the working rod 302. The sealing tube 304 includes an arc-shaped outer tube, one end of the outer tube is fixed on the inner wall of the sample storage cylinder 301 to protect the interior, a rotating shaft 305 is arranged inside the outer tube, and a sealing film is wound around the outside of the rotating shaft 305. The sealing film can be made of cloth or film, and a guide rod 306 is fixedly arranged at the end of the film, one end of the guide rod 306 is fixedly arranged on the working rod 302, and the other end abuts against the inner wall of the sample storage cylinder 301, or a groove is arranged on the inner wall of the sample storage cylinder 301. The other end is slidably arranged in the groove. When in use, after the soil sample enters the sample storage tube 301, the operating rod 205 drives the working rod 302 to rotate, so that the guide rod 306 on the side of the working rod 302 is disengaged from the outside. The guide rod 306 rotates along the working rod 302 as the center of the circle, and the sealing film is pulled out from the rotating shaft 305. The working surface of the guide rod 306 is triangular, which reduces the resistance during rotation. After the guide rod 306 rotates one circle, a layer of sealing film is set above and below the sampled soil to seal the entire soil sample in the sample storage tube 301. After the sealing is completed, the sampling rod body 1 is rotated in the opposite direction to remove the sampling rod body 1 from the soil. After taking it out from the inside, the operating rod 205 is pushed out downward, the card slot is separated from the card connection column, the sample storage barrel 301 is detached from the lower part of the sampling tube 3, and the sample storage barrel 301 is taken out from the inside of the sampling rod body. The soil on the upper and lower parts of the sample storage barrel 301 is cleaned, and the soil sample between the two sealing films is retained, so that the integrity of the soil is better during sampling, and it is convenient to mark, thereby improving the sampling effect. The sample storage barrel can wrap the obtained soil sample in one piece, avoiding the dispersion of the soil sample during the sampling process, so that the obtained soil sample is complete, and no subsequent external planing treatment is required, thereby greatly improving the representativeness of the sample and the accuracy of subsequent analysis work.

[0032] A support column is provided between the sampling tube 3 and the sampling rod body 1 to enhance the structural stability. The top of the sampling tube 3 is designed to be higher than the sampling rod body 1, and a flange bent outward is provided on the top of the sampling tube 3 to facilitate the user to hold it. During continuous sampling, the soil squeezed upward from between the sampling rod body 1 and the sampling tube 3 can flow to the outside of the sampling rod body 1 under the action of the flange, thereby preventing the contamination of the sample inside the sampling tube 3 and improving the sampling effect.

[0033] The drill bit 101 part adopts a conical design as the overall shape, and is divided into a plurality of sector blocks 4. The bottom of the sector block 4 is hinged to the sampling rod body 1 so that they can be opened and closed under the action of a control device. The control device includes a plurality of pull ropes 5 arranged along the length direction of the sampling rod body 1. The top of the pull rope 5 protrudes from the outside of the sampling rod body 1 to facilitate user operation. The pull rope 5 can be arranged inside the interval between the sampling rod body 1 and the sampling tube 3, or a through hole can be opened inside the inner wall along the length direction. The pull rope 5 is arranged inside the through hole. During processing, two layers of metal cylinders can be welded to form a double-layer structure to provide installation space for the pull rope 5 and reduce processing costs. A buckle is provided on the outer wall of the sampling rod body 1. After the pull rope 5 is pulled upward, the handle 501 at the top of the pull rope 5 is clamped on the buckle, which not only realizes the limiting effect, but also ensures the stability of sampling after the sector block 4 is opened.

[0034] The bottom of the pull rope 5 is connected to a slide bar 503, and the fixed block 502 is arranged inside the sampling rod body 1. The slide bar 503 passes through the fixed block 502, and a first spring 504 is arranged on the slide bar 503 below the fixed block 502. The first spring 504 rebounds the slide bar 503 downward, so that the slide bar 503 always has a downward force. An intermediate rod 505 is also hinged at the bottom of the slide bar 503, and a pull rod 506 is hinged at the other end of the intermediate rod 505. Through the hinge between the intermediate rod 505 and the pull rod 506, the deflection angle between the slide bar 503 and the pull rod 506 is increased, so that the fan-shaped Block 4 can be closed and opened to improve the use effect. When drilling downward, under the action of the first spring 504, the slide bar 503 and the pull rod 506 are pushed downward, so that each fan-shaped block 4 is deflected to the middle position to achieve the closing effect. When the drill bit 101 needs to be opened, the pull rope 5 is pulled upward, so that the slide bar 503 drives the pull rod 506 and the fan-shaped block 4 to deflect outward, and then the drill bit 101 is opened, so that the fan-shaped block 4 can automatically open when subjected to external force, and can automatically close through the action of the spring when the external force disappears, thereby achieving the effect of controlling the opening and closing of the drill bit 101, meeting the use needs and improving the control effect.

[0035] The pull rod 506 passes through the abutment block 507 arranged inside the fan-shaped block 4, and the abutment block 507 is fixedly arranged inside the fan-shaped block 4. A sliding block 509 is arranged at the bottom of the pull rod 506, and a second spring 508 is arranged between the sliding block 509 and the abutment block 507. A connecting device for connecting each fan-shaped block 4 is arranged at the bottom of the abutment block 507, and the connecting device includes a first connecting rod 510 hinged with the sliding block 509, and a clamping block 511 is hinged at the bottom of the first connecting rod 510. The clamping block 511 is a rectangular block, and the first connecting rod 510 is hinged to one end of the bottom of the clamping block 511. A through groove for accommodating the clamping block 511 is arranged on the side of the fan-shaped block 4, and one end of the upper part of the clamping block 511 is hinged inside the through groove. One side of the clamping block 511 protrudes from the through groove of the fan-shaped block 4, and the side of the adjacent fan-shaped block 4 is provided with a accommodating groove 401 for accommodating the clamping block 511. When the block 4 is closed, the clamping block 511 on the adjacent sector block 4 can be clamped together with the side receiving groove 401, thereby ensuring the stability of the entire drill bit 101. Inside each sector block 4, one or two groups of first connecting rods 510 can be provided, and there is a height difference, which is convenient for the clamping block 511 to be clamped with the receiving groove 401. When the pull rope 5 is pulled upward, the sliding block 509 drives the first connecting rod 510 to move upward. The first connecting rod 510 is hinged to the bottom of the clamping block 511, so that the bottom of the clamping block 511 moves toward the inside of the sector block 4, and the bottom of the clamping block 511 is disengaged from the inside of the receiving groove 401, and the upper part of the clamping block 511 is set as an inclined surface to reduce the interference of disengagement. After the clamping block 511 is disengaged, the sliding block 509, the second spring 508 and the abutment block 507 achieve the maximum displacement, thereby driving the sector block 4 to deflect outward, thereby realizing the function of opening the drill bit 101.

[0036] When in use, after the sampling rod body 1 reaches the sampling depth, the pull rope 5 is pulled, and after the fan-shaped block 4 is opened, the sampling rod body 1 continues to be rotated. During the downward movement, the sample storage cylinder 301 at the bottom of the sampling tube 3 directly contacts the soil sample at the bottom, and the working rod 302 is rotated to allow the sealing film to wrap the soil. After that, the overall sampling of the soil sample is achieved, which can not only effectively avoid the dispersion and contamination of the soil sample, improve the representativeness of the sample and the accuracy of the subsequent analysis work, but also has the advantages of simple structure, convenient operation, and high sampling efficiency.

[0037] After sampling is completed, a connecting groove for auxiliary resetting is set at the bottom of the clamping block 511. If the second spring 508 is blocked after sampling is completed, when the drill bit 101 is opened, a steel wire can be used to extend into the through groove on the side of the fan-shaped block 4, and the steel wire is clamped with the connecting groove to assist in pulling the clamping block 511 outward, thereby providing a smoother moving path for the clamping block 511, thereby further improving the opening and closing efficiency and stability of the drill bit 101 and improving the use effect.
