Description

Technical Field

[0001] This utility model belongs to the field of soil sampling technology, specifically relating to a soil sampling device for farmland soil remediation. Background Technology

[0002] In existing technologies, when soil contains too many pollutants, affecting and exceeding its self-purification capacity, it produces harmful effects in terms of hygiene and epidemiology, indicating that the soil is polluted. Polluted soil will lead to reduced crop yields and may even cause pollutants in agricultural products to exceed standards, thereby endangering human health. In order to restore the polluted soil so that it can continue to be used, it is necessary to remediate and treat the polluted soil. Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil, reducing their concentration to an acceptable level.

[0003] The quality of farmland soil affects the growth of crops. People need to maintain and manage farmland regularly. During the maintenance and management of farmland, various tests need to be conducted on the soil. Based on the test results, the quality of farmland soil is adjusted to meet the indicators suitable for crop growth. Soil samples must be collected when testing farmland soil.

[0004] Existing soil sampling methods typically involve inserting a sampling tube directly into the lower soil layer and extracting all the soil for collection. This method mixes soil from various depths together, making it impossible to collect soil from the specified depth. Therefore, a soil sampling device for farmland soil remediation is designed to address these issues. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a soil sampling device that facilitates the collection of soil samples at a specified depth.

[0006] The technical solution of this utility model is as follows:

A motor is fixed to the top of the upper seat, and a threaded rod is fixed to the output shaft of the motor. A threaded cylinder is threadedly connected to the lower part of the threaded rod. A sampling cavity is formed in the lower part of the threaded cylinder, and a sealing assembly is provided at the entrance of the sampling cavity. The sealing assembly is rotatably connected to the lower part of the threaded cylinder. Two L-plates are fixed to the lower side of the upper seat to restrict the rotation of the threaded cylinder. A drive assembly for driving the sealing assembly is provided on the lower side of the base, and two pull ropes are fixed to the upper side of the upper seat.

[0008] Furthermore, the sealing assembly includes a turntable rotatably connected to the lower side of the collection port. The turntable is fixed to the lower side of the drive assembly. Multiple connecting plates are rotatably connected to the lower side of the turntable. Each connecting plate has a sealing disc hinged to its end. Each sealing disc is rotatably connected to a threaded cylinder.

[0009] Furthermore, the drive assembly includes a disc rotatably connected to the lower side of the upper seat, a plurality of rotating columns fixed to the lower side of the disc, an insert tube fixed to the lower part of the disc, the insert tube being inserted into a connecting tube, and the lower side of the connecting tube being fixed to the upper part of the turntable.

[0010] Furthermore, the base has multiple insertion holes, each of which is fixed with two guide plates. The positioning rod has guide grooves on both sides, and the positioning rod is slidably connected to the guide plates in the insertion holes through the guide grooves. A conical block is fixed at the bottom of the positioning rod.

[0011] Furthermore, two grooves are formed on the outer ring wall of the threaded cylinder, and the lower ends of the two L-plates are slidably connected in the two grooves respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model can control the height of the sampling chamber through the cooperation of the motor, threaded cylinder, threaded rod and L-plate, and complete the soil sampling at the required depth.

[0014] 2. This utility model can collect soil at a specified depth by means of the cooperation between the sealing component and the driving component, thus preventing the mixing of soil at different depths.

[0015] 3. This utility model facilitates the movement of the data collection device through the combination of the base, upper seat, and pull rope.

[0016] In summary, this invention has the advantage of facilitating the collection of soil samples at a specified depth. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, a soil sampling device for farmland soil remediation includes a base 1, with multiple positioning rods slidably connected to the base 1. An upper seat 3 is fixed to the upper part of the multiple positioning rods 2. A motor 4 is fixed to the top of the upper seat 3. A threaded rod 5 is fixed to the output shaft of the motor 4. A threaded cylinder 6 is threadedly connected to the lower part of the threaded rod 5. A sampling cavity 7 is opened in the lower part of the threaded cylinder 6. A sealing component is provided at the entrance of the sampling cavity 7. The sealing component is rotatably connected to the lower part of the threaded cylinder 6. Two L-plates 8 are fixed to the lower side of the upper seat 3. The two L-plates 8 are used to restrict the rotation of the threaded cylinder 6. A driving component for driving the sealing component is provided on the lower side of the base 1. Two pull ropes 9 are fixed to the upper side of the upper seat 3. The base 1 is fixed to the lower side of the upper seat 3 by a buckle 22.

[0024] When using the collection device, first fix the base 1 to the lower side of the upper seat 3 with the buckle 22, then insert the positioning rod 2 into the farmland soil, and then run the motor 4. The motor 4 drives the threaded rod 5 to rotate, the threaded rod 5 drives the threaded cylinder 6 to move downward, and the threaded cylinder 6 drives the sealing component and the collection chamber 7 to move downward. During the movement, the sealing component is in a closed state, and the lower end of the threaded cylinder 6 is a conical opening.
