Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, specifically a sampling device for soil testing. Background Technology

[0002] A sampling device is a specialized instrument used to collect soil samples, designed to meet the needs of various scenarios such as scientific research, agricultural production, and environmental monitoring. It typically consists of a sampling head, connecting components, and a power mechanism. Sampling heads come in various shapes, such as columnar or spoon-shaped, and can penetrate to specific depths in the soil to obtain samples. The connecting components ensure a stable connection between all parts and allow adjustment of the sampling angle and depth as needed. The power mechanism provides the driving force for sampling; manual models rely on human operation and are suitable for small-scale, shallow sampling, while mechanical or electric models utilize mechanical or electrical power and are suitable for deep, large-area soil sampling, helping people accurately obtain representative soil samples for analyzing information such as soil composition, fertility, and pollution status.

[0003] Existing sampling devices still have some drawbacks in practical applications. First, after collecting soil samples, the existing sampling devices require manual removal of the soil samples collected from the main body of the device, which is time-consuming and laborious. In addition, it will damage the soil sample structure and disrupt the natural arrangement between soil particles, affecting the judgment of soil porosity, aggregates and other structural characteristics, and making the analysis results of soil aeration and water retention inaccurate. Utility Model Content

[0004] The purpose of this invention is to provide a soil sampling device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a soil sampling device, comprising a main body, a column fixedly installed on the top of the main body, a handle fixedly installed on the outer wall of the column, a convenient mechanism provided on the inner wall of the main body, and an auxiliary mechanism provided on the inner wall of the main body. The convenient mechanism includes: a sliding rod slidably installed on the inner wall of the column, and a fixing rod fixedly installed on the outer wall of the sliding rod.

[0006] Preferably, a limiting rod is fixedly installed on the upper surface of the fixed rod, a limiting groove is formed on the inner wall of the limiting rod, a spring is fixedly installed at the end of the slide rod, and a push plate is fixedly installed at the end of the slide rod.

[0007] Preferably, a ramp is slidably mounted on the inner wall of the handle, and a return spring is sleeved on the outer wall of the ramp.

[0008] Preferably, the auxiliary mechanism includes: a scraper, which is slidably mounted on the outer wall of the slide rod, and a push spring is fixedly mounted on the inner wall of the scraper.

[0009] Preferably, one end of the spring is fixedly installed on the end of the slide rod, and the other end of the spring is fixedly installed on the inner wall of the column. One end of the return spring is fixedly installed on the outer wall of the handle, and the other end of the return spring is fixedly installed on the outer wall of the inclined rod. Two sets of inclined rods are provided, symmetrically arranged on the left and right sides with the center line in the vertical direction of the main body as the axis of symmetry. The outer walls of both sets of inclined rods are fixedly installed with return springs. By setting the return springs, the inclined rods can perform a quick reset function.

[0010] Preferably, one end of the push spring is fixedly installed on the inner wall of the scraper, and the other end of the push spring is fixedly installed on the inner wall of the main body. By setting the push spring, the scraper can be moved.

[0011] Compared with the prior art, the present invention provides a soil sampling device, which has the following beneficial effects:

[0012] 1. To avoid the drawbacks of manually removing soil samples from the device, this soil testing sampling device uses a sloped rod that slides along the inner wall of the handle and exits the limiting groove to contact the limiting position. Once the limiting position is released, a spring pushes a sliding rod that slides a push plate downwards along the inner wall of the column. As the push plate slides downwards, it pushes out the soil sample taken from inside the main body. This avoids the damage to the soil sample structure caused by manually removing the soil sample, which disrupts the natural arrangement of soil particles and affects the judgment of soil porosity, aggregates, and other structural characteristics.

[0013] 2. In order to avoid soil residue affecting the next soil sampling, the soil testing sampling device uses a push spring to push the scraper to slide down the inner wall of the main body and clean the soil residue on the inner wall of the main body, thus avoiding soil residue affecting the next soil sample collection.

[0019] like Figures 1-4 As shown, this utility model provides a technical solution: a soil sampling device, including a main body 1, a column 2 fixedly installed on the top of the main body 1, a handle 3 fixedly installed on the outer wall of the column 2, a convenient mechanism 4 provided on the inner wall of the main body 1, and an auxiliary mechanism 5 provided on the inner wall of the main body 1.

[0020] The aforementioned convenient mechanism 4 includes: a slide rod 401, a fixed rod 402, a limiting rod 403, a limiting groove 404, a spring 405, a push plate 406, an inclined rod 407, and a return spring 408. The slide rod 401 is slidably installed on the inner wall of the column 2. The fixed rod 402 is fixedly installed on the outer wall of the slide rod 401. The limiting rod 403 is fixedly installed on the upper surface of the fixed rod 402. The limiting rod 403 has a limiting groove 404 on its inner wall. A spring 405 is fixedly installed at the end of the slide rod 401. One end of the spring 405 is fixedly installed at the end of the slide rod 401, and the other end of the spring 405 is fixedly installed on the inner wall of the column 2. A push plate 406 is fixedly installed at the end of the slide rod 401. An inclined rod 407 is slidably installed on the inner wall of the handle 3. Two sets of inclined rods 407 are provided, with the vertical centerline of the main body 1 as the axis of symmetry. The two inclined rods 407 are symmetrically arranged, and a return spring 408 is fixedly installed on the outer wall of each set of inclined rods 407. The return spring 408 is sleeved on the outer wall of the inclined rod 407. One end of the return spring 408 is fixedly installed on the outer wall of the handle 3, and the other end of the return spring 408 is fixedly installed on the outer wall of the inclined rod 407. Pulling the inclined rod 407 causes it to slide on the inner wall of the handle 3 and exit the contact limit from the limiting groove 404. When the limit is released, the spring 405 will push the slide rod 401, causing the slide rod 401 to push the push plate 406 downward on the inner wall of the column 2. As the push plate 406 slides downward, it will push out the soil sample taken out from the main body 1. This avoids the damage to the soil sample structure caused by manually removing the soil sample, which would disrupt the natural arrangement between soil particles and affect the judgment of soil porosity, aggregates and other structural characteristics.

[0021] The aforementioned auxiliary mechanism 5 includes: a scraper 501 and a push spring 502. The scraper 501 is slidably installed on the outer wall of the slide rod 401, and the push spring 502 is fixedly installed on the inner wall of the scraper 501. One end of the push spring 502 is fixedly installed on the inner wall of the scraper 501, and the other end of the push spring 502 is fixedly installed on the inner wall of the main body 1. The push spring 502 will push the scraper 501 to slide downward on the inner wall of the main body 1 and clean the soil remaining on the inner wall of the main body 1, so as to avoid the soil residue affecting the next soil sample collection.

[0022] Working principle: When soil sampling is required, grasping handle 3 and pressing down causes the main body 1 to insert into the ground and move downwards. As the main body 1 moves downwards, the push plate 406 is compressed by the soil and, with the continuous downward movement of the main body 1, pushes the slide rod 401 upwards along the inner wall of the column 2. Simultaneously, as the slide rod 401 slides upwards, the fixing rod 402 pushes the limiting rod 403 upwards and compresses the inclined rod 407, causing the inclined rod 407 to slide outwards along the inner wall of the handle 3. When the limiting rod 403 slides upwards to its designated position, the return spring 408 pushes the inclined rod 407 to slide back to its original position on the inner wall of the handle 3 and engage with the inner wall of the limiting groove 404 for limiting. Simultaneously, the push plate 406 slides upwards, compressing the scraper 501, causing the scraper 501 to also slide upwards. After sampling is complete, the plate is pulled out. The main body 1 is inserted into the soil. At this time, by pulling the inclined rod 407, the inclined rod 407 slides on the inner wall of the handle 3 and exits the contact limit from the limiting groove 404. When the limit is released, the spring 405 pushes the slide rod 401, which pushes the push plate 406 downward on the inner wall of the column 2. As the push plate 406 slides downward, it pushes out the soil sample taken out from inside the main body 1, avoiding the damage to the soil sample structure caused by manually removing the soil sample. The natural arrangement between soil particles is disrupted, which affects the judgment of soil porosity, aggregates and other structural characteristics. When the push plate 406 slides downward, it releases the pressure on the scraper 501. At this time, the push spring 502 pushes the scraper 501 to slide downward on the inner wall of the main body 1 and cleans the soil remaining on the inner wall of the main body 1, so as to avoid soil residue affecting the next soil sample collection.

[0023] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
