Description

Technical Field

[0001] This utility model belongs to the technical field of soil samplers, specifically relating to a soil sampler for soil pollution prevention and control. Background Technology

[0002] In the work of preventing and controlling soil pollution, it is often necessary to take soil samples from the polluted area. After the soil samples are taken, they are tested. Soil samplers are a commonly used soil sampling device on the market.

[0003] In existing soil samplers, soil samples located inside the shovel barrel are difficult to separate from the original soil layer during the sampling process. In addition, the soil adhesion is stronger as the depth increases, making it difficult to pull the soil sample out along with the shovel barrel, which brings inconvenience to the soil sampling work.

[0004] Therefore, a soil sampler for soil pollution prevention and control is proposed. Summary of the Invention

[0005] This invention provides a soil sampler for soil pollution prevention and control, the purpose of which is to solve the problems mentioned above.

[0006] This utility model provides a soil sampler for soil pollution prevention and control, including a shovel barrel; a top cover disposed at the top of the shovel barrel; a sampling rod disposed at the center of the top of the top cover; main handles symmetrically disposed on the outer side wall of the sampling rod; and a ring-cutting assembly disposed within the shovel barrel. The ring-cutting assembly includes: a lower receiving groove and an upper receiving groove formed inside the shovel barrel; a cutting edge formed on the inner side wall of the shovel barrel; an elastic steel sheet disposed inside the lower receiving groove; a limiting steel plate disposed at the top of the elastic steel sheet; a linkage rod disposed at the center of the top of the limiting steel plate; and a pushing assembly disposed on the outer side of the sampling rod. The pushing assembly includes: a ring sleeve fitted onto the outer side wall of the sampling rod; a crossbar disposed on the outer side wall of the ring sleeve, the crossbar and the linkage rod being fixedly connected; and a spring disposed between the crossbar and the top cover.

[0007] Furthermore, the pushing assembly also includes a spring plunger embedded and fixed to the outer wall of the sampling rod, and two positioning holes are opened on the outer wall of the ring in the vertical direction near the spring plunger, and auxiliary handles are symmetrically arranged on the outer wall of the ring.

[0008] Furthermore, a bulldozer rod is provided through the top of the sampling rod, a bulldozer disc is provided at the bottom end of the bulldozer rod near the inside of the shovel barrel, and a handle is provided at the top of the bulldozer rod.

[0009] By adopting the above technical solution, the soil sample in the shovel can be pushed out by the bulldozer disc, making material collection easy.

[0010] Furthermore, the lower receiving groove is located below the upper receiving groove, and the inner width of the lower receiving groove is smaller than the inner width of the upper receiving groove. The upper receiving groove and the cutting edge are both connected to the lower receiving groove.

[0011] By adopting the above technical solution, a certain limiting space can be formed by the difference in the inner width of the lower receiving groove and the upper receiving groove.

[0012] Furthermore, the angle between the cutting edge and the horizontal plane is 60 degrees;

[0013] By adopting the above technical solution, it is convenient for the elastic steel sheet to be inserted into the shovel barrel 1 at an inclined angle, so as to provide an angle for the deformation of the elastic steel sheet.

[0014] Furthermore, a bevel is provided on one side of the bottom of the elastic steel sheet;

[0015] By adopting the above technical solution, the inclined surface facilitates the smooth insertion of the elastic steel sheet into the soil, thereby achieving the cutting and support of the soil sample.

[0016] Furthermore, the spring plunger and the positioning hole are matched and fitted together;

[0017] By adopting the above technical solution, the movable end of the spring plunger is embedded in the positioning hole to achieve the limiting and fixing of the ring position.

[0018] The beneficial effects of this utility model are as follows:

[0019] This invention utilizes an elastic steel sheet that deforms under inclined guidance and is inserted into the soil sample inside the shovel barrel. This not only severs the connection between the soil sample and the soil layer during subsequent axial movement, achieving separation of the soil sample from the soil layer, but also supports the separated soil sample, making it easier to pull out the soil sample along with the shovel barrel, thus facilitating soil sampling.

[0030] Reference Figure 1-6This utility model embodiment proposes a soil sampler for soil pollution prevention and control, including a shovel barrel 1. A top cover 2 is provided on the top of the shovel barrel 1, and a sampling rod 3 is located at the center of the top of the top cover 2. Two main handles 4 are symmetrically arranged on the outer wall of the sampling rod 3. The shovel barrel 1 has a lower receiving groove 51 and an upper receiving groove 52 in the ring-cutting assembly 5, and a cutting edge 53 is provided on the inner wall of the shovel barrel 1. The lower receiving groove 51 is located below the upper receiving groove 52, and the inner width of the lower receiving groove 51 is smaller than that of the upper receiving groove 52. The upper receiving groove 52 and the cutting edge 53 are both connected to the lower receiving groove 51. The difference in inner width between the lower receiving groove 51 and the upper receiving groove 52 can create a certain limit. The lower receiving groove 51 is equipped with an elastic steel sheet 54. The bottom side of the elastic steel sheet 54 has an inclined surface, which facilitates the smooth insertion of the elastic steel sheet 54 into the soil, thereby cutting and supporting the soil sample. The top of the elastic steel sheet 54 is equipped with a limiting steel plate 55, which limits the limiting space and prevents the elastic steel sheet 54 from detaching from the lower receiving groove 51. A linkage rod 56 is provided at the center of the top of the limiting steel plate 55. The linkage rod 56 passes through the top cover 2. The angle between the cutting edge 53 and the horizontal plane is 60 degrees, which facilitates the insertion of the elastic steel sheet 54 into the shovel barrel 1 at an inclined angle, providing an angle for the deformation of the elastic steel sheet 54.

[0031] The outer wall of the shovel 1 is fitted with a ring 61 from the push assembly 6. Two crossbars 62 are symmetrically arranged on the outer wall of the ring 61. The bottom of the crossbars 62 is fixedly connected to the top of the linkage rod 56. A spring 63 is provided between the bottom of the crossbars 62 and the top of the top cover 2. A spring plunger 64 is embedded in the outer wall of the sampling rod 3. Two positioning holes 65 are opened on the outer wall of the ring 61 in the vertical direction near the spring plunger 64. The spring plunger 64 and the positioning holes 65 are matched and fitted. The ring 61 is limited and fixed in position by the movable end of the spring plunger 64 being embedded in the positioning hole 65. An auxiliary handle 66 is symmetrically arranged on the outer wall of the ring 61.

[0032] A bulldozer rod 7 is installed through the top of the sampling rod 3. A bulldozer disc 8 is installed at the bottom of the bulldozer rod 7 near the inside of the shovel cylinder 1, and a handle 9 is installed at the top of the bulldozer rod 7.

[0033] The specific implementation method is as follows: When taking soil samples, hold the main handle 4 and insert the shovel 1 vertically into the soil using the sampling rod 3. When the shovel 1 is inserted into the soil layer at the required depth, the soil sample is embedded inside the shovel 1. At this time, hold the auxiliary handle 66 and press down. The auxiliary handle 66 pulls the ring sleeve 61 downward. The crossbar 62 on the ring sleeve 61 moves synchronously. Under the connection of the linkage rod 56, the limiting steel plate 55 and the elastic steel plate 54 move downward synchronously. Under the guidance of the cutting edge 53, the elastic... The steel sheet 54 deforms and extends out of the cutting edge 53 at a certain angle. The elastic steel sheet 54 is inserted into the soil sample. When the ring 61 moves down to the lowest point, the movable end of the spring plunger 64 is embedded in the positioning hole 65 located at the high point on the ring 61, realizing the positioning of the ring 61 and thus fixing the position of the elastic steel sheet 54. At this time, the shovel barrel 1 is rotated, and the elastic steel sheet 54 moves axially synchronously. The elastic steel sheet 54 cuts the connection between the soil sample and the soil layer in the shovel barrel 1, and the soil sample and the soil layer break apart and separate.

[0034] The soil sample is extracted from the shovel cylinder 1 by pushing the upper extraction rod 3. Then, the auxiliary handle 66 is pushed upward, and the elastic steel plate 54 is reset and retracted into the lower receiving groove 51. The grip rod 9 is pushed, and with the connection of the bulldozer rod 7, the bulldozer disc 8 pushes the soil sample in the shovel cylinder 1 to push out the soil sample.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
