Description

Technical Field

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

[0002] With current socio-economic development, soil problems are becoming increasingly prominent. Driven by the Soil Pollution Prevention and Control Law, soil environmental surveys are being conducted vigorously across the country, especially monitoring of soil environments at industrial production sites. Due to the heterogeneity of soil, soil sampling is the most crucial step in soil monitoring; accurate collection of soil samples meeting the required standards is essential to ensure the quality of subsequent laboratory data.

[0003] A search revealed Chinese patent CN220670988U, which discloses a topsoil stratification sampler for wetlands. The sampler includes a top plate with a positioning structure at its lower end for positioning the device in wetlands. A threaded rod is threaded onto the top plate, with a rotating wheel welded to its upper end and a sampling structure for wetland soil sampling connected to its lower end. The sampling structure includes a sampling cylinder and a piston plate. The sampling cylinder is located at the lower end of the threaded rod, and longitudinal graduations are provided on its outer wall. The piston plate slides in a sealed manner within the inner cavity of the sampling cylinder. This device is simple in structure and easy to use. By incorporating a sampling structure with a sampling cylinder and piston plate, it is suitable for wetland soil sampling, preventing sample detachment. It also allows for rapid sample collection by pushing the piston plate, which can scrape away sample adhering to the inner wall of the sampling cylinder to prevent sample residue.

[0004] However, the above design still has shortcomings. In the above design, the staff drives the sampling tube downward by turning the handwheel to collect soil. Although the operation is simple, when multiple places need to be sampled, the manual turning of the handwheel frequently results in high labor intensity and low sampling efficiency.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a wetland soil topsoil stratification sampler to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wetland soil topsoil stratification sampler, comprising a top plate, handles fixedly connected to both sides of the top of the top plate, a forward and reverse motor installed between the two handles, a control panel installed on the right side of the forward and reverse motor, a first geared disc fixedly sleeved at the output end of the forward and reverse motor, a second geared disc meshing with the outer wall of the first geared disc, a helical tube fixedly connected inside the second geared disc, a transmission screw threadedly connected to the inner wall of the helical tube, and the lower end of the transmission screw penetrating the top plate and extending to the bottom of the top plate, a transmission plate fixedly connected to the bottom of the transmission screw, a threaded groove formed on the lower surface of the transmission plate, a threaded post threadedly connected to the inner wall of the threaded groove, a sampling cylinder fixedly connected to the bottom of the threaded post, and a hollow ring fixedly connected to the bottom of the sampling cylinder.

[0008] As a further embodiment of this utility model: a power supply box is provided at the rear end of the transmission screw, and a storage battery is installed inside the power supply box.

[0009] As a further embodiment of this utility model: the rear end face of the power supply box is rotatably provided with a movable door, the surface of the movable door is provided with a heat dissipation groove, and a dustproof net is fixedly installed inside the heat dissipation groove.

[0010] As a further embodiment of this utility model: the outer walls of the top plate are all fixedly connected with support plates, and the number of support plates is four. The end of the support plate away from the top plate is fixedly connected with an installation block.

[0011] As a further embodiment of this utility model: the bottom of the mounting block is fixedly connected with a plug rod, and the plug rod is made of stainless steel.

[0012] As a further embodiment of this utility model: both sides of the top of the transmission plate are fixedly connected with limit rods, and the upper end of the limit rods penetrates through the top plate and extends to the top of the top plate.

[0013] This utility model has the following beneficial effects:

[0014] (1) Through the structural design of the limiting rod, transmission screw, first gear plate, forward and reverse motor, transmission plate, sampling cylinder, solenoid and second gear plate, it is possible to easily drive the sampling cylinder to move downward, thereby completing soil sampling. The operation is simple, the labor intensity is low and the sampling efficiency is high. At the same time, the setting of the limiting rod can limit the transmission plate to avoid its rotation affecting the movement of the sampling cylinder. This solves the problem that although the operation is simple, when multiple places need to be sampled, the manual frequent turning of the handwheel leads to high labor intensity and low sampling efficiency.

[0015] (2) Through the structural design of the power supply box, movable door, heat dissipation groove, dustproof net, storage battery, threaded groove and threaded column, the sampling tube can be easily disassembled, cleaned and installed, which can effectively ensure the soil sampling effect and thus improve the practicality of the device. At the same time, the storage battery can provide power to the electrical appliances required by the device, thereby improving the convenience of the device. The heat dissipation groove facilitates the dissipation of heat generated by the storage battery during operation. The dustproof net can effectively prevent external dust from entering the box during the heat dissipation process. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0024] It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0026] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please see Figure 1-5 An embodiment of this utility model provides a wetland soil topsoil stratification sampler, including a top plate 3, handles 2 fixedly connected to both sides of the top of the top plate 3, a forward and reverse motor 8 installed between the two handles 2, a control panel 16 installed on the right side of the forward and reverse motor 8, a first gear plate 7 fixedly sleeved at the output end of the forward and reverse motor 8, a second gear plate 15 meshing with the outer wall of the first gear plate 7, a screw tube 14 fixedly connected inside the second gear plate 15, a transmission screw 6 threadedly connected to the inner wall of the screw tube 14, and the lower end of the transmission screw 6 penetrating the top plate 3 and extending to the bottom of the top plate 3, a transmission plate 9 fixedly connected to the bottom of the transmission screw 6, a sampling cylinder 10 fixedly connected to the bottom of the threaded column 22, and a hollow ring 12 fixedly connected to the bottom of the sampling cylinder 10.

[0028] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, when it is necessary to move the sampling cylinder 10 downward to collect soil samples, the forward and reverse motor 8 can be started through the control panel 16. The output end of the forward and reverse motor 8 can drive the first gear plate 7 to rotate. The rotation of the first gear plate 7 drives the screw tube 14 to rotate through the second gear plate 15. The rotation of the screw tube 14 drives the transmission screw 6 to move downward. The downward movement of the transmission screw 6 drives the sampling cylinder 10 downward through the transmission plate 9, thereby completing the soil sampling. The operation is simple, the labor intensity is low, and the sampling efficiency is high. At the same time, the setting of the limit rod 1 can limit the transmission plate 9 to prevent its rotation from affecting the movement of the sampling cylinder 10. This solves the problem that although the operation is simple, when multiple locations need to be sampled, the frequent manual turning of the handwheel to move the sampling cylinder 10 downward results in high labor intensity and low sampling efficiency.

[0029] Specifically, by controlling the downward position of the transmission screw 6, the depth of the sampling cylinder 10 in the soil can be adjusted to meet the requirements of soil sampling at different depths.

[0030] The lower surface of the transmission plate 9 is provided with a threaded groove 21, and a threaded post 22 is threadedly connected to the inner wall of the threaded groove 21. A power supply box 13 is provided at the rear end of the transmission screw 6. A storage battery 20 is installed inside the power supply box 13. A movable door 17 is rotatably provided on the rear end face of the power supply box 13. A heat dissipation groove 18 is provided through the surface of the movable door 17. A dustproof net 19 is fixedly installed inside the heat dissipation groove 18. Support plates 4 are fixedly connected to the outer walls of the top plate 3. There are four support plates 4. An installation block 5 is fixedly connected to the end of the support plate 4 away from the top plate 3. An insertion rod 11 is fixedly connected to the bottom of the installation block 5. The insertion rod 11 is made of stainless steel. Limiting rods 1 are fixedly connected to both sides of the top of the transmission plate 9. The upper end of the limiting rod 1 passes through the top plate 3 and extends to the top of the top plate 3.

[0031] Specifically, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, when the sampling cylinder 10 needs to be disassembled and cleaned, it can be disassembled by rotating the sampling cylinder 10 until the threaded post 22 at the top of the sampling cylinder 10 disengages from the threaded groove 21. Similarly, the sampling cylinder 10 can be installed. By making the sampling cylinder 10 easy to disassemble, clean and install, the soil sampling effect can be effectively guaranteed, thereby improving the practicality of the device. At the same time, the battery 20 can provide power to the electrical components required by the device, thereby improving the convenience of the device. The heat dissipation groove 18 facilitates the dissipation of heat generated by the battery 20 during operation. The dustproof net 19 effectively prevents external dust from entering the box during the heat dissipation process.

[0032] Among them, the cooperation of multiple insertion rods 11 makes it easy to fix the device, thereby making it easier to take soil samples later.

[0033] Working principle: In this application, when it is necessary to move the sampling cylinder 10 downwards for soil sampling, the forward and reverse motor 8 can be started through the control panel 16. The output end of the forward and reverse motor 8 drives the first gear plate 7 to rotate. The rotation of the first gear plate 7 drives the solenoid tube 14 to rotate through the second gear plate 15. The rotation of the solenoid tube 14 drives the transmission screw 6 to move downwards. The downward movement of the transmission screw 6 drives the sampling cylinder 10 downwards through the transmission plate 9, thereby completing the soil sampling. The operation is simple, the labor intensity is low, and the sampling efficiency is high. Furthermore, by controlling the downward movement of the transmission screw 6... The sampling tube 10 is positioned so that its depth in the soil can be adjusted to meet soil sampling at different depths. Finally, the sampling tube 10 can be disassembled by rotating it until the threaded post 22 at the top of the sampling tube 10 disengages from the threaded groove 21. Similarly, the sampling tube 10 can be installed. By facilitating the disassembly, cleaning and installation of the sampling tube 10, the soil sampling effect can be effectively guaranteed, thereby improving the practicality of the device. At the same time, the battery 20 can provide power to the electrical components required by the device, thereby improving the convenience of the device.
