Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, and in particular to a sampler for detecting heavy metals in soil. Background Technology

[0002] Soil heavy metal pollution refers to the excessive accumulation of trace metal elements in the soil due to human activities, resulting in levels exceeding a certain threshold.

[0003] Based on the comparison of existing technologies, after the soil sampler is used, since the soil to be tested is inside the drill bit, the staff needs to use tools to manually remove the soil, which makes the sampling process more troublesome, time-consuming and labor-intensive. Furthermore, the soil near the inside cannot be completely removed, which affects the next use and leads to a decrease in the accuracy of the test. In addition, the existing sampler may tilt when it is pointing downwards, making it difficult to remove later, thus reducing the sampling efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a soil sampler for heavy metal detection, which allows for rapid soil extraction, facilitating testing by staff, while also securing the device to prevent the drill barrel from tilting.

[0005] To achieve the above objectives, a sampler for detecting heavy metals in soil is provided, comprising a sleeve, wherein a soil sampling mechanism is provided inside the sleeve, and a fixing mechanism is provided on the surface of the sleeve.

[0006] The soil sampling mechanism includes a threaded rod, with a handle fixedly connected to the upper end of the threaded rod and a fixed column fixedly connected to the lower end of the threaded rod. A drill barrel is fixedly connected to the lower end of the fixed column. A disc is slidably connected to the surface of the fixed column. A telescopic rod is fixedly connected to the lower end of the disc. A spring is fixedly connected to the upper end of the telescopic rod. A fixed rod is fixedly connected to the lower end of the disc. A disc is fixedly connected to the lower end of the fixed rod. A sliding groove is formed on the surface of the fixed column.

[0007] According to the aforementioned soil heavy metal testing sampler, the fixing mechanism includes a fixing plate, a threaded rod II is internally threaded to the fixing plate, a knob is fixedly connected to the upper end of the threaded rod II, and a base plate is fixedly connected to the surface of the sleeve.

[0008] According to the aforementioned soil heavy metal testing sampler, the threaded rod is positioned inside the sleeve and is threadedly connected to the inside of the sleeve. Through the threaded connection between the threaded rod and the inside of the sleeve, the fixed column fixedly connected to the lower end of the threaded rod rotates up and down.

[0009] According to the aforementioned soil heavy metal testing sampler, the fixing rod is positioned inside the drill barrel and is slidably connected to the inside of the drill barrel. This slidable connection allows the fixing rod to move up and down more stably.

[0010] According to the aforementioned soil heavy metal testing sampler, the first disc is positioned inside the sliding groove, and the first disc is slidably connected to the inside of the sliding groove. Through the slidable connection between the first disc and the inside of the sliding groove, when the first disc moves, the sliding groove limits its movement, thus allowing the first disc to move up and down more stably. Furthermore, the sliding groove prevents the first disc from getting stuck on the surface of the threaded rod.

[0011] According to the aforementioned soil heavy metal sampler, the drill barrel is positioned inside the sleeve, and the drill barrel fits snugly against the inside of the sleeve. This snug fit between the drill barrel and the inside of the sleeve allows for more stable up-and-down rotation of the drill barrel.

[0012] According to the aforementioned soil heavy metal sampler, the fixing plate is positioned on the surface of the sleeve, and the fixing plate is fixedly connected to the surface of the sleeve. This fixed connection between the fixing plate and the surface of the sleeve enables the device to operate more stably.

[0013] According to the aforementioned soil heavy metal sampler, the second threaded rod is positioned inside the base plate and is threadedly connected to the inside of the base plate. This threaded connection between the second threaded rod and the inside of the base plate allows the device to operate more effectively.

[0014] This utility model has the following beneficial effects:

[0015] 1. Compared with existing technologies, by rotating the handle, the threaded rod rotates downwards, which in turn rotates the fixed column and the drill barrel, thus drilling into the ground and allowing soil to enter the drill barrel. Then, rotating the handle in the opposite direction rotates the drill barrel upwards, moving it away from the ground. Continuing to rotate the handle moves the threaded rod away from the sleeve, placing the fixed column at the lower end of the threaded rod inside the sleeve. Pulling the handle then causes the disc to press against the sleeve, moving the fixed rod downwards and causing the disc to move as well, allowing the soil to be quickly removed for easy testing.

[0016] 2. Compared with existing technologies, when the device is extracting soil, the bottom plate is first placed on the surface of the soil to keep it at the same level. Then, the knob is turned, which simultaneously drives the threaded rod to rotate downwards, thereby fixing the device and preventing the drill barrel from tilting and affecting the soil extraction efficiency, thus further enhancing the practicality of the device.

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-4 This utility model provides a soil heavy metal detection sampler, which includes a sleeve 1, a soil sampling mechanism 2 inside the sleeve 1, and a fixing mechanism 3 on the surface of the sleeve 1.

[0026] The soil extraction mechanism 2 includes a threaded rod 21, which is located inside the sleeve 1 and is threadedly connected to the inside of the sleeve 1. This threaded connection drives the fixed column 23, which is fixedly connected to the lower end of the threaded rod 21, to rotate up and down. A handle 22 is fixedly connected to the upper end of the threaded rod 21, and the fixed column 23 is fixedly connected to the lower end of the threaded rod 21. A drill barrel 24 is fixedly connected to the lower end of the fixed column 23, located inside the sleeve 1 and fitting snugly against the inside of the sleeve 1. This snug fit allows for more stable up-and-down rotation of the drill barrel 24. A disc 25 is slidably connected to the surface of the fixed column 23, located inside a sliding groove 210. The disc 25 fits snugly against the surface of the sliding groove 210. The disc 25 is slidably connected to the inside of the sliding groove 210. This allows the disc 25 to move more stably up and down by being limited by the sliding groove 210. The sliding groove 210 also prevents the disc 25 from getting stuck on the surface of the threaded rod 21. The lower end of the disc 25 is fixedly connected to a telescopic rod 26, and the upper end of the telescopic rod 26 is fixedly connected to a spring 27. The lower end of the disc 25 is fixedly connected to a fixing rod 28, which is located inside the drill barrel 24. The fixing rod 28 is slidably connected to the inside of the drill barrel 24, allowing it to move more stably up and down. The lower end of the fixing rod 28 is fixedly connected to a disc 29, and the surface of the fixing post 23 has a sliding groove 210.

[0027] The fixing mechanism 3 includes a fixing plate 31, which is positioned on the surface of the sleeve 1 and is fixedly connected to the surface of the sleeve 1. This fixed connection between the fixing plate 31 and the surface of the sleeve 1 makes the device operate more stably. A threaded rod 32 is threadedly connected to the inside of the fixing plate 31. The threaded rod 32 is positioned inside the base plate 34 and is threadedly connected to the inside of the base plate 34. This threaded connection between the threaded rod 32 and the inside of the base plate 34 makes the device operate better. A knob 33 is fixedly connected to the upper end of the threaded rod 32. The base plate 34 is fixedly connected to the surface of the sleeve 1.

[0028] Working principle: In use, first turn the handle 22, which simultaneously drives the threaded rod 21 to rotate downwards. This causes the fixed post 23, which is fixedly connected to the lower end of the threaded rod 21, to rotate downwards as well. Simultaneously, the drill barrel 24, which is fixedly connected to the lower end of the fixed post 23, rotates downwards as well, thus drilling into the ground and allowing soil to enter the drill barrel 24. Then, turn the handle 22 in the opposite direction, which simultaneously drives the drill barrel 24 to rotate upwards, moving it away from the ground. Continue turning the handle 22, which moves the threaded rod 21 away from the sleeve 1, thus placing the fixed post 23 at the lower end of the threaded rod 21 inside the sleeve 1. Finally, pull the handle 22, which simultaneously causes the surface of the fixed post 23 to slide. The connected disc 25 squeezes the sleeve 1, which in turn moves the fixed rod 28, which is fixedly connected to the lower end of the disc 25, downward. At the same time, the disc 29, which is fixedly connected to the lower end of the fixed rod 28, moves accordingly, so that the soil can be quickly removed for easy testing. Then, the device is restored by the telescopic rod 26 and the spring 27, so that it can be tested again. When the device is removing soil, the base plate 34 is first placed on the surface of the soil to keep it at the same level. Then, the knob 33 is turned, which drives the threaded rod 32 to rotate downward, thereby fixing the device and preventing the drill cylinder 24 from tilting, which would affect the efficiency of soil removal and further enhance the practicality of the device.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
