Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sampling equipment, in particular to a soil sampling device for environmental detection. Background Technique
[0002] Soil environmental monitoring is an important part of ecological environment monitoring and an important measure to understand the soil environmental quality status. Soil environmental monitoring includes aspects such as the current situation investigation of soil environmental quality, the investigation of regional soil environmental background values, the investigation of soil pollution accidents, and the dynamic observation of polluted soil.
[0003] In soil environmental monitoring, sampling devices are usually used for soil sampling. There are various existing sampling devices, such as manual insertion type, which is flexible and convenient to use and carry, and is generally used in areas with soft soil; electric spiral type, which is used for automatic sampling in cooperation with a drill bit and is relatively labor-saving, and is generally used in areas with relatively hard soil. However, for some special areas, such as the site on the bank of a river, where there is mostly mud, many roots of weeds and trees, and occasional interspersed gravel. For such a site, neither of the above two methods is very applicable. When using the manual insertion type, when a person manually inserts it into the soil, once encountering plant roots or gravel, it is very difficult to continue inserting, which is quite laborious; when using the electric spiral type, due to the relatively wet soil by the river and mostly clay, it is very difficult to remove the soil from the spiral blades after spiral sampling, and it is difficult to clean. Content of the Utility Model
[0004] In view of the above deficiencies of the prior art, the utility model provides a soil sampling device for environmental detection. A person holds the support rod with one hand, keeps the sampling tube and the limit rod vertical, and inserts them into the soil. Once encountering plant roots or gravel, the other hand quickly smashes the counterweight from top to bottom onto the backing plate, and through inertia, the bottom of the sampling tube breaks the roots or gravel, and continues to extend downward. The structure is simple and convenient to use. The soil in the cavity of the sampling tube can be completely taken out by opening the side door, and even for clay, it is convenient to take out.
[0005] To achieve the above objectives, the utility model is realized through the following technical solutions: A soil sampling device for environmental detection, including a sampling tube, a backing plate, a limit rod, and a counterweight.

A limit hole is arranged at the center of the counterweight, and the counterweight is vertically movably sleeved on the limit rod through the limit hole. A pair of support rods are arranged on the side wall of the backing plate.
[0006] Preferably, the pipe head is made of cemented carbide material, and the bottom of the pipe head is chamfered to form a sharp corner.

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0016] Such as Figure 1As shown in the figure, a soil sampling device for environmental detection includes a sampling tube 3, a backing plate 5, a limiting rod 7 and a counterweight 9. The upper end of the sampling tube 3 is fixedly connected to the center of the bottom of the backing plate 5, and the lower end is fixedly provided with a pipe head 2. The sampling tube 3 is provided with a cavity 12 with an open bottom. A side door 13 is rotatably arranged on the side wall of the sampling tube 3. The lower end of the limiting rod 7 is fixedly connected to the center of the upper surface of the backing plate 5, and the upper end is connected to a top plate 8. The counterweight 9 is provided with a limiting hole 10 at the center, and the counterweight 9 is vertically movably sleeved on the limiting rod 7 through the limiting hole 10. A pair of support rods 11 are arranged on the side wall of the backing plate 5; the pipe head 2 is made of cemented carbide material, and the bottom of the pipe head 2 is chamfered to form a sharp angle 1; a plurality of barbed clamping plates 14 are uniformly arranged on the inner side wall of the pipe head 2; a scale mark 4 is arranged on the side wall of the sampling tube 3; a rubber sleeve 6 is arranged on the support rod 11.
[0017] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, which are as follows:
[0018] According to the appended drawings of the specification Figure 1 It can be seen that when the present utility model works, a person holds the support rod 11 and makes the sampling tube 3 vertical. The person presses down the support rod 11 forcefully to insert the sampling tube 3 into the soil. When encountering plant roots or gravel, the person holds the support rod 11 with one hand and quickly smashes the counterweight 9 from top to bottom towards the backing plate 5. Through inertia, the sampling tube 3 is instantaneously impacted downward, so that the pipe head 2 at the bottom of the sampling tube 3 breaks the roots or gravel, and thus continues to extend downward. Compared with the existing manually inserted type, where a person inserts with brute force, the working intensity will be reduced, and the structure is simple and easy to use. The soil in the cavity 12 of the sampling tube 3 is collected. After pulling out the sampling tube 3, the side door 13 is opened, and the soil at the desired position is taken out. Even for clay, the side door 13 can be opened conveniently to take out the soil at any position. Compared with the existing electric spiral type in the prior art, the material taking is more convenient and the position is more accurate.
[0019] Among them, the pipe head 2 is made of cemented carbide material, which is convenient for breaking plant roots and gravel, and is not easily damaged, improving the service life. At the same time, the bottom of the pipe head 2 is chamfered to form a sharp angle 1, which is convenient for inserting into the soil.
[0020] Among them, a plurality of barbed clamping plates 14 are uniformly arranged on the inner side wall of the pipe head 2, which reduces the outflow of soil when the sampling tube 3 is pulled out.
[0021] Among them, a scale mark 4 is arranged on the side wall of the sampling tube 3. After pulling out the sampling tube 3, the soil at the specified position can be accurately selected with reference to the scale mark 4.
[0022] Among them, a rubber sleeve 6 is arranged on the support rod 11. When the counterweight 9 hits the backing plate 5, vibration will be generated, and the person holding the rubber sleeve 6 can reduce the vibration to the hand.
[0023] Another possible implementation of the present utility model is that when encountering plant roots or gravel, a person holds the top plate 8 by hand and steps on the supporting rod 11 downward with the foot, and uses the weight of the person to insert the sampling tube 3 downward to break the plant roots or gravel, and the person will also be relatively labor-saving.
[0024] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model, and the scope of the present utility model is defined by the appended claims and their equivalents.
