Description

Technical Field

[0001] This utility model relates to the field of environmental engineering technology, specifically to an environmental engineering soil testing sampler. Background Technology

[0002] In environmental engineering, soil samplers are used to collect soil samples, which are then tested and analyzed to target soil pollution sources for remediation and treatment, thereby achieving the goal of environmental governance.

[0003] Publication number CN215640234U discloses a soil testing sampler for environmental engineering. This patent uses a fixed base, connectors, connecting shafts, support rods, and rubber pads. The three sets of support rods form a triangular support structure, which can stably and quickly fix the sampler during use, making it convenient to use without spending a lot of time fixing the sampler. It is simple and convenient. However, this patent still has the following problems in actual use:

[0004] The three sets of support rods, consisting of a fixed base, connector, connecting shaft, support rod, and rubber pad, form a triangular support structure. This structure can stably and quickly fix the sampler during use, making it convenient for the sampler to use. However, in actual use, after soil sampling is completed, the soil sample will remain inside the ring drill bit. If the soil sample has a lot of moisture, the sample will adhere to the ring drill bit, making it difficult to remove the soil sample.

[0005] An environmental engineering soil testing sampler is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide an environmental engineering soil testing sampler to solve the problem mentioned in the background art. The current method uses a fixed base, connector, connecting shaft, support rod, and rubber pad to form a triangular support structure. While this structure can stably and quickly fix the sampler during use, making it convenient, in actual use, after soil sampling, the soil sample remains inside the ring drill bit. If the soil sample has a high moisture content, the sample will adhere to the ring drill bit, making it difficult to remove the soil sample.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an environmental engineering soil testing sampler, comprising a column rod;

[0008] A mounting rod is fixedly installed on the top of the column, and a handrail is fixedly installed on the top of the mounting rod.

[0011] The sampling component includes a sliding groove inside the column, and a sliding rod is slidably connected inside the sliding groove. A sampling slot is provided at the bottom inside the column, and a sliding plate is slidably connected inside the sampling slot.

[0012] The sliding plate is fixedly connected to the sliding rod, and a movable groove is provided on one side of the rod above the sliding groove. A movable rod is fixedly installed on one side of the sliding rod, and the movable rod is slidably connected to the movable groove.

[0013] Preferably, a movable ring is slidably connected to the upper outer side of the column rod, and a guide rod is fixedly installed on the top side of the movable ring. A positioning block is slidably connected to the outer side of the guide rod, and the positioning block is fixedly connected to the column rod.

[0014] Preferably, a positioning rod is slidably connected to one side of the movable ring, and several positioning grooves are opened on the upper side of the other side of the rod, and the positioning rod is engaged with the positioning grooves.

[0015] Preferably, a telescopic spring is sleeved on the outer side of the positioning rod, and one end of the telescopic spring is fixedly connected to the movable ring, and a handle is fixedly installed on the other end of the telescopic spring, and the handle is fixedly connected to the positioning rod.

[0016] Preferably, mounting brackets are symmetrically installed on the side of the movable ring away from the positioning rod, and a rotating shaft is rotatably connected between the two mounting brackets on one side. A push rod is fixedly installed on one side of the rotating shaft, and a rotating rod is fixedly installed on the other side of the rotating shaft.

[0017] Preferably, the positioning component includes a circular plate disposed below the outside of the column rod, with a through groove opened at the top of the circular plate, and fixing brackets symmetrically installed on the top of the circular plate. A sleeve is fixedly installed between the two fixing brackets, and the column rod is slidably connected to the sleeve. A limit ring is fixedly installed on the outside of the column rod below the sleeve. Moving rods are symmetrically slidably connected to the two sides inside the circular plate, and mounting blocks are fixedly installed at the bottom of the moving rods. Receiving grooves are opened above the two mounting blocks at the bottom of the circular plate. A return spring is sleeved on the outside of the moving rod, with one end of the return spring fixedly connected to the circular plate and the other end of the return spring fixedly installed with a fixing block, which is fixedly connected to the moving rod.

[0018] Preferably, the top of the circular plate is symmetrically equipped with support frames on one side of the two moving rods, and a rotating gear is rotatably connected above the two support frames. The interior of the circular plate is slidably connected with positioning columns on one side of the two moving rods. Mounting plates are fixedly installed on the side of the positioning columns that are close to the fixing blocks. Racks are fixedly installed on the side of the two mounting plates that are close to each other, and the two racks are meshed with the rotating gear.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This environmental engineering soil testing sampler has sampling components set inside and outside the column, which can control the sampling depth and facilitate the user to remove the soil sample after sampling, avoiding the soil sample from becoming loose, which facilitates subsequent testing and improves convenience and practicality. The specific details are as follows:

[0020] 1. Sampling components are installed inside and outside the column. When sampling soil, pull the handle to move the positioning rod on the movable ring according to the sampling needs. This stretches the telescopic spring, disengaging the positioning rod from the positioning groove. The position of the movable ring can be adjusted. After adjustment, align the positioning rod with another positioning groove. Release the handle, and the telescopic spring will engage the positioning rod with the positioning groove, positioning the movable ring. The moving distance of the movable rod can be adjusted through the movable ring, facilitating the adjustment of the sampling depth. Insert the column into the area to be sampled, and press down on the column by the handle. The bottom of the column has a ring cutter, allowing the column to be inserted into the soil, and the soil can enter the sampling groove for sampling. After entering the trough, the sliding plate and sliding rod can be pushed to move until the movable rod abuts against the movable ring, stopping the downward pressure on the column rod to continue sampling. Pulling out the column rod allows the rotating rod to rotate, causing the rotating shaft to rotate. After the rotating shaft rotates, the push rod abuts against the movable rod. As the rotating rod rotates, the push rod can push the movable rod to move. Using the lever principle, the movable rod can be initially moved, allowing the sliding plate to move initially. After the sliding plate moves, it can push the soil sample downward. Then, continuing to move the movable rod can push the soil sample out. The sampling depth can be controlled through the sampling component, and the soil sample can be easily removed by the user after sampling, avoiding the soil sample from becoming loose, facilitating subsequent testing, and improving convenience and practicality.

[0021] 2. Before sampling, place the circular plate on the ground with the two mounting blocks in contact with the ground. The user can step on the circular plate to make it fit against the ground, allowing the mounting blocks to retract into the receiving groove. This allows the moving rod and the circular plate to move relative to each other, enabling the rack on one side of the mounting plate to drive the rotating gear. After the rotating gear rotates, it meshes with the rack on the other side, causing the other side of the mounting plate to move downwards, allowing the positioning column to move down and insert into the soil. This positions the circular plate. The column can slide on the sleeve, supporting its movement and preventing it from tilting due to soft soil. This also prevents the circular plate from moving during sampling, thus avoiding affecting the sampling accuracy. After sampling, the circular plate is lifted so that the bottom of the positioning column does not protrude from the circular plate, making it easy to carry and preventing the circular plate from being difficult to move as a whole.

The handle 213 is fixedly connected to the positioning rod 210, so that the positioning rod 210 can automatically reset after moving. The movable ring 207 is symmetrically installed with mounting brackets 214 on the side away from the positioning rod 210, and a rotating shaft 215 is rotatably connected between the two mounting brackets 214 on one side. A push rod 216 is fixedly installed on one side of the rotating shaft 215, and a rotating rod 217 is fixedly installed on the other side of the rotating shaft 215, which can push the soil sample to move initially with relatively little effort.

[0031] The positioning component 3 includes a circular plate 301 disposed below the outside of the column rod 1. A through slot is formed at the top of the circular plate 301, and symmetrically mounted fixing brackets 302 are installed on the top of the circular plate 301. A sleeve 303 is fixedly installed between the two fixing brackets 302, and the column rod 1 is slidably connected to the sleeve 303. A limit ring 304 is fixedly installed below the sleeve 303 on the outside of the column rod 1. Sliding rods 305 are symmetrically slidably connected to both sides of the inside of the circular plate 301, and mounting blocks 306 are fixedly installed at the bottom of the sliding rods 305.

An mounting plate 311 is fixedly installed on the side of the positioning column 310 that is close to the fixing block 3052. A rack 312 is fixedly installed on the side of the two mounting plates 311 that is close to each other. The two racks 312 are meshed with the rotating gear 309 to position the circular plate 301 and prevent the circular plate 301 from moving accidentally and affecting the sampling accuracy.

[0032] Working principle: Before using this type of environmental engineering soil testing sampler, it is necessary to check the overall condition of the device to ensure it can function normally. Figure 1 - Figure 5As shown, sampling components 2 are installed inside and outside the column 1. When sampling the soil, the handle 213 is pulled according to the sampling requirements, causing the positioning rod 210 to slide on the movable ring 207. This stretches the telescopic spring 212, disengaging the positioning rod 210 from the positioning groove 211, allowing adjustment of the position of the movable ring 207. After adjustment, the positioning rod 210 is aligned with the other positioning groove 211. Releasing the handle 213 causes the positioning rod 210 to engage with the positioning groove 211 under the action of the telescopic spring 212, positioning the movable ring 207. The movable ring 207 allows adjustment of the movement distance of the movable rod 206, facilitating adjustment of the sampling depth. The column 1 is inserted into the area to be sampled. Pressing down on the column 1 with the handle, the bottom end of the column 1 is a ring cutter, allowing the column 1 to be inserted into the soil, and the soil to enter the sampling groove 203. After sampling in the sampling slot 203, the sliding plate 204 and sliding rod 202 can be pushed to move until the movable rod 206 abuts against the movable ring 207 to stop pressing down the column rod 1 to continue sampling. Pull out the column rod 1, and the rotating rod 217 can be rotated to drive the rotating shaft 215 to rotate. After the rotating shaft 215 rotates, the push rod 216 abuts against the movable rod 206. As the rotating rod 217 rotates, the push rod 216 can push the movable rod 206 to move. With the help of the lever principle, the movable rod 206 can be moved initially, so that the sliding plate 204 can be moved initially. After the sliding plate 204 moves, it can push the soil sample down. Then, continue to move the movable rod 206 to push the soil sample out. The sampling depth can be controlled by the sampling component 2, and the soil sample can be easily removed by the user after sampling, avoiding the soil sample from being loose, which is convenient for subsequent testing and improves convenience and practicality.

[0033] Before sampling, the circular plate 301 is placed on the ground, with the two mounting blocks 306 in contact with the ground. The user can then step on the circular plate 301 to make it adhere to the ground, allowing the mounting blocks 306 to retract into the receiving groove 307. This allows relative movement between the moving rod 305 and the circular plate 301, enabling the rack 312 on one side of the mounting plate 311 to drive the rotating gear 309 to rotate. The rotating gear 309, after rotating, can then engage with the rack 312 on the other side to drive the other... The side mounting plate 311 moves down, causing the positioning column 310 to move down and insert into the soil, thereby positioning the circular plate 301. The column rod 1 can slide on the sleeve 303 to support the movement of the column rod 1, preventing the column rod 1 from tilting due to the soft soil. It also prevents the circular plate 301 from moving during the sampling process, thus avoiding affecting the sampling accuracy. After the sampling is completed, the circular plate 301 is lifted so that the bottom end of the positioning column 310 does not protrude from the circular plate 301, making it easy to carry and preventing the circular plate 301 from being difficult to move as a whole.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
