Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, and more specifically, to a soil pollution sampling device for pollution prevention and control. Background Technology

[0002] Soil, as a vital component of the ecosystem, not only provides the foundation for plant growth but also participates in numerous ecological processes such as the water cycle and climate regulation. Once soil is polluted, pollutants can be transferred through the food chain, posing a serious threat to human health and the ecological environment. Accurately understanding the soil pollution status is a crucial prerequisite for effective prevention and control of soil pollution. This requires obtaining representative soil samples through soil sampling to analyze the types, concentrations, and distribution of pollutants in the soil, providing a basis for developing scientifically sound pollution prevention and control measures.

The base has a cavity, the fixing component is located within the cavity, the moving wheels are mounted on the base, the support column is mounted on the base, the top plate is mounted on the support column, the electric cylinder is mounted on the top plate, and the output end of the electric cylinder slides through the top plate to below it. The sliding plate is located on the output end of the electric cylinder and is slidably sleeved on the support column. The sampling cylinder is mounted on the sliding plate, the soil drilling component is mounted on the sampling cylinder, and the sampling cylinder contains a sampling chamber. This utility model relates to the field of waste treatment equipment technology, specifically providing a soil pollution sampling device for pollution prevention that is easy to move and fix, has higher flexibility, stronger stability, higher automation, and better practicality. However, it still has the following drawbacks:

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this embodiment proposes a soil pollution sampling device for pollution prevention and control, including a mounting cover 1, a mounting tube 2 inside the mounting cover 1, a rotating mechanism 3 inside the mounting cover 1 for driving the mounting tube 2 to rotate, a rod sleeve 4 fixedly connected to the top end of the mounting tube 2, a connecting rod 5 slidably connected inside the rod sleeve 4, a telescopic mechanism 6 inside the mounting cover 1 for driving the connecting rod 5 to rise and fall, a set of mounting holes evenly opened on the left side wall of the mounting tube 2, and a sampling tube 7 slidably connected to each mounting hole, a tube seat 8 threadedly connected to the inner end of the sampling tube 7, a connecting ear 9 fixedly connected to the side wall of the tube seat 8 away from the sampling tube 7, a connecting rod 10 rotatably connected to the connecting ear 9, and a connecting block 11 rotatably connected to the top end of the connecting rod 10. The mounting tube 2 is fixedly connected to the connecting rod 5, and the bottom end of the mounting tube 2 is fixedly connected to the base plate 12. The lower end face of the base plate 12 is fixedly connected to the drill rod 13. The mounting cover 1 provides a foundation for the installation of the components. At the same time, the overall sampling device is small in size and easy to carry. The connecting rod 5 is driven to descend by the telescopic mechanism 6. The descent of the connecting rod 5 drives the connecting block 11 to descend synchronously, thereby causing the connecting rod 10 to move. The movement of the connecting rod 10 pushes the tube seat 8 and the sampling tube 7 to move outward and insert into the soil, thereby realizing the sampling of soil at different depths in a single operation, which significantly improves the sampling efficiency. The sampling tube 7 and the tube seat 8 are connected by threads for easy disassembly, which makes it easy to take out the soil sample from the sampling tube 7, and also makes it easy to replace and clean the sampling tube 7.

[0031] like Figure 1 and Figure 5As shown, in a preferred embodiment, based on the above method, the rotating mechanism 3 further includes a disc 301 fixed to the top of the mounting tube 2. Three limiting seats 302 are evenly provided on the outside of the disc 301. The bottom ends of the three limiting seats 302 are fixedly connected to the inner bottom wall of the mounting cover 1. A gear ring 303 is rotatably connected inside the three limiting seats 302. The inner side wall of the inner ring of the gear ring 303 is fixedly connected to the outer side wall of the outer ring of the disc 301. A motor 304 is fixedly connected to the lower end face of the mounting cover 1. The driving end of the motor 304 passes through the bottom wall of the mounting cover 1 and is fixedly connected to a gear 305 that meshes with the gear ring 303. The motor 304 drives the gear 305 to rotate, and the gear 305 drives the gear ring 303 to rotate, thereby causing the disc 301 and the mounting tube 2 to rotate. The rotation of the mounting tube 2 can drive the drill rod 13 to rotate, and the drill rod 13 can easily drill into the soil, providing a basis for subsequent soil sampling.

[0032] like Figure 1 , Figure 3 and Figure 6 As shown, in a preferred embodiment, based on the above method, the telescopic mechanism 6 further includes two circular blocks 601 fixed to the top of the connecting rod 5, a lifting plate 602 between the two circular blocks 601, a bracket 603 on the upper side of the lifting plate 602, the bottom end of the bracket 603 being fixedly connected to the inner bottom wall of the mounting cover 1, and an electric telescopic rod 604 being fixedly connected to the upper end face of the bracket 603. The driving end of the electric telescopic rod 604 passes through the bracket 603 and is fixedly connected to the upper end face of the lifting plate 602. The center of the lifting plate 602 and the center of the circular plate 301 are on the same central axis. The lifting plate 602 is driven to rise and fall by the electric telescopic rod 604. The rising and falling of the lifting plate 602 drives the two circular blocks 601 and the connecting rod 5 to rise and fall simultaneously. When the connecting rod 5 rises and falls, the tube seat 8 and the sampling tube 7 slide in the mounting hole through the connecting block 11, the connecting rod 10 and the connecting ear 9, realizing the extension and retraction of the sampling tube 7. When the sampling tube 7 is extended, it can be inserted into the soil for sampling, which facilitates the entry of soil into the sampling tube 7.

[0033] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, handles 14 are fixedly connected to the left and right side walls of the mounting cover 1, and anti-slip sleeves 15 are fixedly fitted on the handles 14; the handles 14 and anti-slip sleeves 15 facilitate the operator to hold and sample, and the downward force applied by the handles 14 causes the drill rod 13 to drill into the soil, providing a basis for subsequent soil sampling.

[0034] like Figure 3 and Figure 4As shown, in a preferred embodiment, based on the above method, a fixing ear 16 is fixedly connected to the bottom of the tube seat 8, and a guide rod 17 is slidably connected inside the fixing ear 16. The outer end of the guide rod 17 is fixedly connected to the inner side wall of the mounting tube 2. The guide rod 17 plays a guiding role to ensure that the tube seat 8 and the sampling tube 7 slide stably.

[0035] like Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the sampling tube 7 is further provided with a strip-shaped opening 18, and the bottom of the mounting cover 1 is provided with a circular opening 19 that cooperates with the mounting tube 2. The diameter of the circular opening 19 is smaller than the diameter of the disc 301. The strip-shaped opening 18 makes it convenient for the sampling personnel to use tools to remove all the soil samples remaining in the sampling tube 7, so as to avoid interference with the next use. The circular opening 19 facilitates the rotation of the mounting tube 2, providing a basis for the rotation and installation of the mounting tube 2.

[0036] Specifically, when using this soil pollution sampling device for pollution prevention and control: First, hold the handle 14 and position the drill rod 13 perpendicular to the soil being sampled. Then, the motor 304 drives the gear 305 to rotate, which in turn drives the gear ring 303 to rotate, causing the disc 301 and the mounting tube 2 to rotate. The rotation of the mounting tube 2 drives the drill rod 13 to rotate. Simultaneously, a downward force is applied through the handle 14 to lower the drill rod 13 into the soil, causing the mounting tube 2 to descend into the soil. The electric telescopic rod 604 drives the lifting disc 602 to descend. The descent of the lifting disc 602... The two circular blocks 601 and the connecting rod 5 descend simultaneously. The descent of the connecting rod 5 causes the connecting block 11 to descend synchronously, which in turn causes the connecting rod 10 to move. The movement of the connecting rod 10 pushes the tube seat 8 and the sampling tube 7 to move outward and insert into the soil. Then, the electric telescopic rod 604 retracts to reset the sampling tube 7, and the sampling device is taken out. Then, the electric telescopic rod 604 drives the sampling tube 7 to leak out, and the sampling tube 7 is removed from the sampling device. Then, the soil in the sampling tube 7 is sampled. Soil samples at different depths can be collected in a single sampling, which significantly improves the sampling efficiency.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
