Description

Technical Field

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

[0002] Soil testing is a crucial agricultural activity involving a series of analytical processes designed to assess the physical, chemical, and biological properties of the soil. These properties directly impact crop growth and yield. The primary objective of soil testing is to determine the nutrient content in the soil, including major nutrients such as nitrogen, phosphorus, and potassium, as well as micronutrients such as iron, manganese, and zinc. Soil testing typically involves sample collection and sample analysis, with the accuracy of sample collection being critical to the subsequent test results.

[0003] Soil sample collection requires the use of a soil sampler. Many existing soil samplers can only sample in batches at different depths on the same vertical plane. This not only causes significant soil interference but is also time-consuming and labor-intensive. Furthermore, after each soil sample is collected, it needs to be transferred to a sample bottle before sampling at the next location. During the transfer process, the soil sample is exposed to the air for a long time, which can affect the test results. Therefore, there is a need for a sampler that can perform layered sampling of soil at different depths in one go and can quickly transfer the sample to a sample bottle to reduce contact with air. Utility Model Content

[0004] To address the technical problems of existing soil samplers, which often only allow batch sampling at different depths along the same vertical axis, resulting in significant soil interference, time and labor costs, and the need to transfer soil samples to sample bottles before moving on to the next location, which exposes the soil samples to air for extended periods and affects the test results, this invention provides a soil sampler.

[0005] A soil sampler includes an outer frame with a through groove on the bottom wall of the outer frame. A sampling tube is movably mounted on the through groove. Several through holes are provided horizontally through the sampling tube. A cover plate is movably mounted on the outer wall of the sampling tube to cover the through holes. A container box is fixedly mounted next to the sampling tube. Several receiving slots are provided inside the container box, and the positions of the receiving slots correspond one-to-one with the positions of the through holes. Several container bottles are movably placed inside the container box. A push plate is provided through the inner wall of the receiving slot to push the container bottles to move along the direction of the through holes.

[0006] More preferably, the push plate includes a main push plate and several auxiliary push plates. The top and bottom walls of the outer frame are provided with a set of sliding grooves. The two ends of the main push plate are slidably disposed on the set of sliding grooves. Several auxiliary push plates are fixedly disposed on the side walls of the main push plate, and their number is consistent with the receiving groove. The telescopic ends of the auxiliary push plates are disposed inside the receiving groove.

[0007] More preferably, hydraulic cylinders are provided on the top wall and side wall of the outer frame, and the output end of the hydraulic cylinders is provided with a first telescopic rod and a second telescopic rod, respectively. The telescopic end of the first telescopic rod is fixedly installed on the top wall of the sampling cylinder, and the telescopic end of the second telescopic rod is fixedly installed on the outer wall of the main push plate.

[0008] More preferably, the bottom of the sampling tube is provided with an electrically telescopic bottom cover, the side wall of the sampling tube is a hollow structure, and a bayonet is movably provided inside. A limiting groove is provided on the outer wall of the bottom end of the sampling tube, and the bayonet can slide or be fixed on the limiting groove.

[0009] More preferably, the outer wall of the sampling tube is also equipped with a scale to mark the depth of penetration into the ground, with several through holes corresponding to the scale.

[0010] More preferably, the cover plate includes several circular baffles, the number of which is the same as the number of through holes, and the size of the circular baffles is larger than the size of the through holes. The diameter of the bottle body of several containers is smaller than the diameter of several through holes. The several circular baffles are connected to each other by a set of connecting rods. A pull rod is fixedly installed on the top wall of the topmost circular baffle. The pull rod passes through the top wall of the sampling cylinder and can move up and down.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the sampling tube passes through the through groove to sample the soil, the scale can indicate the sampling depth, and the soil can be sampled in layers on a vertical plane at one time. After the sample is obtained, it is aligned with the container box. First, the cover plate on the side near the container bottle is opened, and the push plate is activated to push the container bottle through the through hole to dispense the soil inside the sampling tube. Then, the cover plate on the side away from the container box is opened, the container bottle containing the soil is pulled out and the lid is closed, which greatly shortens the contact time between the soil and the air.

The following will refer to the accompanying drawings. Figures 1-6 The present invention will be described in detail with reference to the embodiments.

[0024] A soil sampler includes an outer frame 1, a through groove 2 on the bottom wall of the outer frame 1, a sampling cylinder 3 movably mounted on the through groove 2, an electrically telescopic bottom cover 22 at the bottom of the sampling cylinder 3, the electrically telescopic bottom cover 22 can be an automatic telescopic bottom cover in the prior art, a hydraulic cylinder 10 is mounted on the top wall of the outer frame 1, and a first telescopic rod 11 is mounted on the output end of the hydraulic cylinder 10.

[0025] When taking a sample, first open the electric telescopic bottom cover 22, then start the hydraulic cylinder 10 to drive the first telescopic rod 11 to move downward. Since the telescopic end of the first telescopic rod 11 is fixedly set on the top wall of the sampling cylinder 3, the sampling cylinder 3 moves through the through groove 2 to the ground soil and takes a sample.

[0026] The sampling cylinder 3 has a hollow sidewall structure, with a movable bayonet 16 inside. A limiting groove 17 is provided on the outer bottom wall of the sampling cylinder 3, allowing the bayonet 16 to slide or be fixed within it. Before sampling, press the bayonet 16 to extend it downwards along the limiting groove 17 from the bottom wall of the sampling cylinder 3. After extension, the bayonet 16 is fixed in the limiting groove 17 and moves downwards in conjunction with the first telescopic rod 11, facilitating easier penetration into the ground soil, resulting in faster sampling and less soil disturbance. When not in use, slide the bayonet 16 back into the sidewall of the sampling cylinder 3 to avoid accidental cuts.

[0027] The sampling tube 3 is horizontally penetrating and has several through holes 4. The outer wall of the sampling tube 3 is also equipped with a scale 18 to mark the depth of penetration into the ground. The through holes 4 and the scale 18 correspond one-to-one. Different scales on the upper and lower parts of the scale 18 correspond to soil sampling from different layers.

[0028] The outer wall of the sampling tube 3 is movably equipped with a cover plate 5, which can block several through holes 4. The cover plate 5 includes several circular cover plates 20. The number of circular cover plates 20 is the same as the number of through holes 4, and their size is larger than the size of the through holes 4. This can cover the through holes 4 and prevent soil leakage. The diameter of the bottle body of several container bottles 7 is smaller than the diameter of several through holes 4, which can ensure that the container bottles 7 can pass through the through holes 4 and the soil can be put into the container bottles 7.

[0029] Several circular shields 20 are interconnected by a set of connecting rods 21. A pull rod 19 is fixedly installed on the top wall of the topmost circular shield 20. The pull rod 19 passes through the top wall of the sampling cylinder 3 and can move up and down. When it is necessary to expose the through hole 4 for the container bottle 7 to fill with soil, the pull rod 19 is pulled, causing it to move the lower circular shield 20 and the connecting rod 21 upwards a certain distance, so that the circular shield 20 and the through hole 4 are just misaligned and cannot be covered. Then, the container bottle 7 passes through the through hole 4 under the pushing action of the push plate 9. The container bottle 7 with the opening is used to fill the soil in layers for sampling.

[0030] A container box 6 is fixedly installed next to the sampling tube 3. The container box 6 has several receiving slots 8 inside, and the positions of the receiving slots 8 and several through holes 4 are one-to-one. Several container bottles 7 can be placed inside the container box 6. The container bottles 7 can be used to dispense soil samples and can be reused. When sampling, the container bottles 7 can be placed inside the receiving slots 8. The receiving slots 8 are covered by an outer cover through a hinge to ensure that the container bottles 7 are clean and hygienic.

[0031] A pusher plate 9 is installed through the inner wall of the receiving groove 8, which can push the container bottle 7 to move along the direction of the through hole 4. The pusher plate 9 includes a main pusher plate 14 and several auxiliary pusher plates 15. A hydraulic cylinder 10 is installed on the side wall of the outer frame 1. A second telescopic rod 12 is installed at the output end of the hydraulic cylinder 10. The telescopic end of the second telescopic rod 12 is fixedly installed on the outer wall of the main pusher plate 14. When dispensing samples, the hydraulic cylinder 10 is activated, which drives the second telescopic rod 12 to move towards the container box 6. The second telescopic rod 12 drives the main pusher plate 14 to move towards the through hole 4, which in turn causes the main pusher plate 14 to drive the several auxiliary pusher plates 15 to push the container bottle 7 inside the receiving groove 8 towards the direction of the through hole 4.

[0032] The top and bottom walls of the outer frame 1 are each provided with a set of sliding grooves 13. The two ends of the main push plate 14 are slidably mounted on the set of sliding grooves 13, which can enhance the stability and directionality during pushing. Several auxiliary push plates 15 are fixedly mounted on the side walls of the main push plate 14, and their number is consistent with that of the receiving groove 8. The telescopic ends of the auxiliary push plates 15 are located inside the receiving groove 8. The container bottle 7 is pushed by the push plate 9 to pass through the left side of the through hole 4 to take a sample, and then it is taken out from the right side of the through hole 4. The cap is then tightened, and the one-time soil stratification sampling and dispensing is completed.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
