Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling, and more specifically, to a soil sampling device for detecting soil heavy metals. Background Art

[0002] Heavy metal pollution refers to environmental pollution caused by heavy metals or their compounds; it is mainly caused by human factors such as mining, exhaust emissions, sewage irrigation and the use of products with excessive heavy metal content. Therefore, the soil will also contain heavy metals. The excessive heavy metal content in some soils will affect their use, so there will be a special testing instrument for soil sampling and testing to determine whether the heavy metal content in the soil exceeds the standard.

[0003] However, when the existing soil sampling and testing instruments detect the metal content in the soil, the detection probe is directly inserted into the soil for detection without cleaning the impurities in the soil. If there are weeds or stones in the soil, the detection probe will be damaged, resulting in insensitivity of the detection probe. Therefore, a soil sampling device for soil heavy metal detection is proposed to improve the existing problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a soil sampling device for detecting heavy metals in soil.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a soil sampling device for soil heavy metal detection, comprising a support assembly, a sampling assembly and a filter assembly; wherein the support assembly comprises a base plate, a support plate symmetrically arranged on the top of the base plate in the axial direction, and a clamping plate symmetrically arranged in the middle of the support plate in the radial direction; the sampling assembly is arranged in the middle of the support plate, and comprises a rotating motor, a rotating gear arranged at the output end of the rotating motor, a transmission gear meshing with the rotating gear, a sampling barrel arranged in the center hole of the transmission gear, and a discharge barrel arranged on the side wall of the sampling barrel; the filter assembly is arranged at one end of the discharge barrel away from the sampling barrel, and comprises a telescopic cylinder symmetrically arranged on both sides of the discharge barrel in the axial direction, and a filter plate arranged in the discharge barrel.

[0006] The utility model is further configured as follows: the support plate is triangular in shape, the inclined edges of the support plate are distributed above the bottom plate, the two ends of the clamping plate can be connected to the side walls of the corresponding support plate, and the clamping plate and the support plate are distributed vertically.

[0007] The utility model is further configured as follows: the clip-on plate includes a first clip-on plate and a second clip-on plate, the end faces of the first clip-on plate and the second clip-on plate are both U-shaped, the structural structures and sizes of the first clip-on plate and the second clip-on plate are the same, and the first clip-on plate is located above the second clip-on plate; a first pulley is symmetrically arranged in the axial direction in the recess of the first clip-on plate, and the first pulley can be rotatably connected to the inner wall of the first clip-on plate, and a second pulley is symmetrically arranged in the axial direction in the recess of the second clip-on plate, and the second pulley can be rotatably connected to the inner wall of the second clip-on plate.

[0008] The utility model is further configured as follows: the sampling barrel is inclined, fixed rings are provided at both ends of the outer wall of the sampling barrel, annular grooves are provided on the outer wall of the fixed ring, and the first pulley and the second pulley can both slide in the annular grooves; a spiral sheet is spirally arranged inside the sampling barrel, filter holes are evenly provided on the outer wall of one end of the sampling barrel, the filter holes are spirally distributed, and partition holes are evenly provided at one end of the filter holes, and the partition holes are also spirally distributed.

[0009] The utility model is further configured as follows: the filtering holes and the separation holes can be communicated with the discharge cylinder, and a collecting cylinder is further arranged below the discharge cylinder, and the collecting cylinder is located on the bottom plate.

[0011] By adopting the above technical solution, one end of the filter plate is pushed out of the discharge barrel by the telescopic cylinder, so that the filter plate is in an inclined state. Due to the factor of gravity, the impurities falling on the filter plate roll off the filter plate, and the soil still passes through the holes of the filter plate and falls into the collecting barrel, thereby achieving the purpose of screening and separating the impurities in the soil during the sampling process, avoiding damage to the probe of the detector when performing soil detection, thereby improving the sensitivity of the detection probe and further increasing the service life of the detection probe.

[0012] In summary, the present application includes at least one of the following beneficial technical effects:

The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0025] See also Figure 1-Figure 5 , the utility model provides the following technical solutions:

[0026] Example 1, see Figure 1-Figure 5A soil sampling device for soil heavy metal detection includes a support component 1, a sampling component 2 and a filtering component 3; wherein the support component 1 provides support for the sampling component 2 and the filtering component 3, and tilts the sampling component 2 to facilitate soil sampling; the sampling component 2 takes soil samples from the land to be detected, so as to facilitate subsequent detection work; and the filtering component 3 screens and separates impurities in the soil during the sampling process, so as to avoid damage to the probe when the detector performs soil detection, thereby improving the sensitivity of the detection probe and further improving the service life of the detection probe.

[0027] See also Figure 1-Figure 2 Specifically, the support assembly 1 includes a base plate 11, a support plate 12 symmetrically arranged on the top of the base plate 11 in the axial direction M, and a clamping plate 13 symmetrically arranged in the middle of the support plate 12 in the radial direction N; the support plate 12 is triangular, and the inclined edges of the support plate 12 are distributed above the base plate 11, and the two ends of the clamping plate 13 can be connected to the side walls of the corresponding support plate 12, and the clamping plate 13 and the support plate 12 are vertically distributed.

[0028] Among them, through the design of the support plate 12 and the clamping plate 13, the sampling tube 24 is tilted and distributed in the middle of the support plate 12, so that one end of the sampling tube 24 can be used to lift and collect soil, and transport the soil into the sampling tube 24, thereby achieving the purpose of soil sampling.

[0029] See also Figure 3-Figure 4 Specifically, the sampling assembly 2 is arranged in the middle of the support plate 12, and includes a rotating motor 21, a rotating gear 22 arranged at the output end of the rotating motor 21, a transmission gear 23 meshing with the rotating gear 22, a sampling cylinder 24 arranged in the center hole of the transmission gear 23, and a discharge cylinder 25 arranged on the side wall of the sampling cylinder 24.

[0030] When sampling the soil, the rotating motor 21 is started, and its output end drives the rotating gear 22 to rotate, and the transmission gear 23 and the sampling barrel 24 also rotate accordingly. During this process, the sampling barrel 24 can sample the soil and transport the sampled soil to the discharge barrel 25 for collection, so as to facilitate subsequent detection work and improve the sampling efficiency.

[0031] See also Figure 5 Specifically, the filter assembly 3 is arranged at one end of the discharge barrel 25 away from the sampling barrel 24, and includes a telescopic cylinder 31 symmetrically arranged on both sides of the discharge barrel 25 in the axial direction M, and a filter plate 32 arranged in the discharge barrel 25; one end of the filter plate 32 can be rotatably connected to the inner wall of the discharge barrel 25, and the side wall of the other end can be connected to the corresponding telescopic cylinder 31.

[0032] Among them, the telescopic cylinder 31 is started and its output end is extended. Since one end of the filter plate 32 can be rotatably connected to the inner wall of the discharge barrel 25, and the side wall of the other end can be connected to the corresponding telescopic cylinder 31, its output end can push one end of the filter plate 32 out of the discharge barrel 25, so that the filter plate 32 is in an inclined state. Due to the factor of gravity, impurities falling on the filter plate 32 roll off the filter plate 32, and the soil still passes through the holes of the filter plate 32 and falls into the collecting barrel 26, thereby achieving the purpose of screening and separating impurities in the soil during the sampling process, avoiding damage to the probe when the detector performs soil detection, thereby improving the sensitivity of the detection probe, and then improving the service life of the detection probe.

[0033] See also Figure 1-Figure 2 Furthermore, the clamping plate 13 includes a first clamping plate 131 and a second clamping plate 132, the end surfaces of the first clamping plate 131 and the second clamping plate 132 are both U-shaped, the structures of the first clamping plate 131 and the second clamping plate 132 are the same in size, and the first clamping plate 131 is located above the second clamping plate 132; a first pulley 133 is symmetrically arranged in the axial M direction in the recess of the first clamping plate 131, and the first pulley 133 can be rotatably connected to the inner wall of the first clamping plate 131, and a second pulley 134 is symmetrically arranged in the axial M direction in the recess of the second clamping plate 132, and the second pulley 134 can be rotatably connected to the inner wall of the second clamping plate 132.

[0034] The sampling barrel 24 is tilted, and fixed rings 241 are provided at both ends of the outer wall of the sampling barrel 24. An annular groove 242 is provided on the outer wall of the fixing ring 241, and the first pulley 133 and the second pulley 134 can slide in the annular groove 242; a spiral sheet 243 is spirally arranged inside the sampling barrel 24, and filter holes 244 are evenly provided on the outer wall of one end of the sampling barrel 24, and the filter holes 244 are spirally distributed. Partition holes 245 are also evenly provided at one end of the filter holes 244, and the partition holes 245 are also spirally distributed.

[0035] The filtering holes 244 and the partitioning holes 245 can be communicated with the discharge cylinder 25 . A collecting cylinder 26 is further provided below the discharge cylinder 25 . The collecting cylinder 26 is located on the bottom plate 11 .

[0036] Among them, through the mutual cooperation of the first clamping plate 131, the second clamping plate 132, the first pulley 133, and the second pulley 134, when the sampling tube 24 rotates for sampling, it will rotate on the first pulley 133 and the second pulley 134 through the annular groove 242 of the fixing ring 241, thereby reducing friction and increasing the service life of the sampling tube 24.

[0037] When sampling, the sampling tube 24 rotates and the spiral blade 243 also rotates. During this process, the spiral blade 243 will lift the soil around the spiral blades and transport it to the sampling tube 24, thereby achieving the purpose of sampling; when the soil is transported to the filter hole 244, the soil falls through the filter hole 244 onto the filter plate 32, and then falls from the holes of the filter plate 32 into the collection tube 26 to facilitate subsequent detection work.

[0038] Obviously, the embodiments described above are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
