Description

Technical Field

[0001] The present invention relates to the technical field of soil detection, and in particular to a portable soil sampling device for ecological environment detection. Background Art

[0002] Soil environmental monitoring is an important measure to understand the status of soil environmental quality. With the goal of preventing and controlling soil pollution hazards, it involves dynamic analysis and measurement of soil pollution levels and development trends. This includes surveys of current soil environmental quality, investigations of regional soil environmental background values, investigations of soil pollution accidents, and dynamic observations of contaminated soil. Soil environmental monitoring generally involves preparation, site placement, sampling, sample preparation, analysis and testing, and evaluation. Quality control / quality assurance should be implemented throughout.

[0003] The main methods of soil environmental testing are:

[0004] 1. Simple random

[0005] The monitoring unit is divided into grids, each grid is numbered, and after the number of samples at the sampling point is determined, the specified number of samples are randomly selected. The grid number corresponding to the sample number is the sampling point. Random numbers can be obtained by rolling dice, drawing lots, or looking up a random number table.

[0006] 2. Block randomization

[0007] Based on the collected data, if the soil within the monitoring area has several distinct types, the area can be divided into several blocks, where the pollutants are relatively uniform within each block and the differences between blocks are more obvious. Each block is considered a monitoring unit, and random points are then randomly distributed within each monitoring unit. If the blocks are divided correctly, the representativeness of the points distributed in blocks is better than that of simple random points. If the blocks are divided incorrectly, the effect of the points distributed in blocks may be counterproductive.

[0008] 3. System randomness

[0009] Divide the monitoring area into several equal sections (grid division), with one sampling point placed within each grid. This method is called systematic random sampling. If soil contaminant levels vary significantly within an area, systematic random sampling will yield more representative samples than simple random sampling.

[0010] When the soil is sampled for pollutants, some sand and gravel particles may be present above or inside the soil. To prevent the sand and gravel particles from being mixed with the sampled soil and causing inaccurate detection, the sand and gravel need to be cleaned manually. The manual cleaning process is cumbersome, and some of the sand and gravel particles inside the soil have strong adhesion to the soil and are difficult to clean directly, which brings certain inconveniences to soil detection.

DETAILED DESCRIPTION

[0033] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0034] like Figures 1-9 As shown, the present invention provides a technical solution: a portable soil sampling device for ecological environment detection, comprising a shell 1, a first fixing ring 12 is fixedly connected to the outer surface of the shell 1, an armrest 13 is fixedly connected to the outer surface of the first fixing ring 12, a second fixing ring 2 is fixedly connected to the outer surface of the second fixing ring 2, a first fixing frame 6 is fixedly connected to the outer surface of the first fixing frame 6, a support leg 7 is rotatably connected to the outer surface of the first fixing frame 6, an end of the support leg 7 away from the first fixing frame 6 is fixedly connected to a ground nail 8, a collection device 4 is provided on the inner wall of the shell 1, and an oscillation device 3 is provided on the lower surface of the shell 1;

[0035] The oscillation device 3 includes an oscillation motor 34. An oscillation head 37 is provided on the lower surface of the oscillation motor 34. The oscillation head 37 is connected to the output end of the oscillation motor 34. The oscillation head 37 includes an oscillation column 371. The outer surface of the oscillation column 371 at the end away from the oscillation motor 34 is fixedly connected to a first support frame 372. The upper surface of the first support frame 372 is fixedly connected to a third fixing ring 373. The upper surface of the third fixing ring 373 is fixedly connected to a first elastic piece 374. The end of the first elastic piece 374 away from the third fixing ring 373 is fixedly connected to an impact column 375.

[0036] It should be noted here that: by setting the oscillating head 37, the soil on the surface can be made loose, thereby achieving the effect of separating the sand and gravel from the soil, and then achieving the effect of collecting the sand and gravel in the soil. During operation, after installing the device, the operator turns on the switch of the oscillating motor 34, and the oscillating motor 34 starts working, which will cause the oscillating column 371 to produce high-intensity vibration. During the vibration process, the first spring piece 374 drives the impact column 375 to produce a violent impact on the ground, and during the impact process, the originally hard soil will become loose.

[0037] The oscillation device 3 includes a base plate 31, which is fixedly connected to the lower surface of the housing 1. The oscillation column 371 passes through the base plate 31. A second support frame 32 is fixedly connected to the upper surface of the base plate 31. The end of the second support frame 32 away from the base plate 31 is fixedly connected to the outer surface of the housing 1. A third support frame 33 is fixedly connected to the outer surface of the second support frame 32. The end of the third support frame 33 away from the second support frame 32 is fixedly connected to the outer surface of the oscillation motor 34.

[0038] It should be noted here that when in use, the operator places the entire device on the ground surface where data needs to be collected, and then fixes the support legs 7 to the ground surface and inserts the ground spikes 8 into the soil, so that the device is firmly fixed to the ground surface.

[0039] A second fixing bracket 35 is fixedly connected to the outer surface of the oscillation motor 34 away from the third support bracket 33. One end of the second fixing bracket 35 away from the oscillation motor 34 is fixedly connected to the outer surface of the housing 1. A connecting ring 36 is fixedly connected to the side surface of the oscillation motor 34.

[0040] It should be noted here that: by setting the oscillating head 37, the soil on the surface can be made loose, thereby achieving the effect of separating the sand and gravel in the soil, and then achieving the separation and collection of sand and gravel in the soil, removing the sand and gravel above and inside the soil to be sampled and collected, so that after the collection device 4 is operated and the soil falling from the entire device no longer contains sand and gravel, thereby facilitating subsequent soil detection work. During operation, after the device is installed, the operator turns on the switch of the oscillation motor 34, and the oscillation motor 34 starts working, which will cause the oscillation column 371 to generate high-intensity vibration. During the vibration process, the first spring piece 374 drives the impact column 375 to produce a violent impact on the ground, and during the impact process, the originally hard soil will become loose.

[0041] A collection box 11 is movably connected to the inner wall of the housing 1, a top cover 10 is fixedly connected to the upper surface of the collection box 11, and a lifting handle 9 is fixedly connected to the upper surface of the top cover 10;

[0042] It should be noted here that the entire top cover 10 and the collection box 11 can be easily pulled by pulling the handle 9 .

[0043] The collecting device 4 includes a circular support frame 41, which is fixedly connected to the inner wall of the housing 1. A rotating motor 42 is provided on the upper surface of the circular support frame 41. A rotating column 43 is fixedly connected to the output end of the rotating motor 42. A spiral plate 44 is fixedly connected to the outer surface of the rotating column 43 away from the rotating motor 42.

[0044] It should be noted here that: when the spiral plate 44 drives the sand and gravel to move upward, the sand and gravel will enter the inner cavity of the collecting frame 47. The stones in the inner cavity of the collecting frame 47 will be thrown into the inner cavity of the collecting box 11 when the rotating motor 42 stops rotating, thereby achieving the separation and collection of sand and gravel in the soil to be sampled, removing the sand and gravel above and inside the soil to be sampled, so that after the operation of the collection device 4 is completed and the soil falling from the entire device no longer contains sand and gravel, thereby facilitating subsequent soil testing work.

[0045] A fourth fixing ring 45 is fixedly connected to the outer surface of the rotating column 43 , a support column 46 is fixedly connected to the outer surface of the fourth fixing ring 45 , and a collection frame 47 is fixedly connected to one end of the support column 46 away from the fourth fixing ring 45 ;

[0046] It should be noted here that: during operation, the operator turns on the rotating motor 42, and the rotating motor 42 starts working, which will drive the rotating column 43 to rotate. During the rotation of the rotating column 43, the spiral plate 44 will dig the soil and drive the soil and sand and gravel upward.

[0047] A sand and gravel separation device 5 is provided on the inner wall of the housing 1. The sand and gravel separation device 5 includes a fifth fixing ring 51, which is fixedly connected to the inner wall of the housing 1. A third fixing frame 52 is fixedly connected to the upper surface of the fifth fixing ring 51. A slot is provided on the outer surface of the third fixing frame 52. A first separation plate 53 is fixedly connected to the slot provided on the outer surface of the third fixing frame 52. A second elastic piece 54 is fixedly connected to the lower surface of the first separation plate 53.

[0048] It should be noted here that: during the rotation of the rotating column 43, the spiral plate 44 will dig the soil and drive the soil and sand and gravel to move upward. By setting up the sand and gravel separation device 5, the sand and gravel in the soil can be separated from the soil, thereby facilitating the collection of sand and gravel. During operation, under the action of the spiral plate 44, the soil and sand and gravel will be driven to move upward.

[0049] A second separation plate 55 is fixedly connected to the inner wall of the fifth fixing ring 51. A third elastic piece 56 is fixedly connected to the end of the second separation plate 55 away from the fifth fixing ring 51. A fourth fixing bracket 57 is fixedly connected to the end of the third elastic piece 56 away from the second separation plate 55. The end of the fourth fixing bracket 57 away from the third elastic piece 56 is fixedly connected to the inner wall of the housing 1.

[0050] It should be noted here that: during operation, under the action of the spiral plate 44, the soil and sand and gravel will be driven to move upward. During the upward movement, the sand and gravel and soil will hit the second separation plate 55. Since the second separation plate 55 is arranged relatively densely, the sand and gravel will be retained on the upper surface of the second separation plate 55, and the soil will fall back to the surface. The separated sand and gravel will move upward again under the action of the spiral plate 44 and hit the first separation plate 53 again, thereby achieving a secondary separation of sand and gravel from soil.

[0051] The internal components of the collection device 4 and the sand and gravel separation device 5 are made of polyformaldehyde. The collection device 4 and the sand and gravel separation device 5 components made of polyformaldehyde ensure the functionality of the collection device 4 and the sand and gravel separation device 5 themselves, while avoiding the collection device 4 and the sand and gravel separation device 5 being made of metal components, which causes metal elements to stick to the soil after collection, thereby facilitating subsequent heavy metal data detection of the soil.

[0052] When sampling and testing soil, first, by setting the support legs 7 and the ground spikes 8, the entire device can be fixed on the ground. When in use, the operator places the entire device on the surface where sampling is required, and then fixes the support legs 7 on the surface and drives the ground spikes 8 into the soil, so that the device is firmly fixed on the surface.

[0053] After the entire fixing device is fixed, the oscillating head 37 is set to make the surface soil loose, thereby achieving the effect of separating the sand and gravel in the soil, and then achieving the effect of collecting the sand and gravel in the soil. During operation, the operator turns on the switch of the oscillating motor 34, and the oscillating motor 34 starts to work, which will cause the oscillating column 371 to generate high-intensity vibration. During the vibration process, the first elastic piece 374 drives the impact column 375 to produce a violent impact on the ground, and the impact process will make the originally hard soil loose. By setting the collecting box 11, the sand and gravel in the soil can be separated and collected, and the sand and gravel above and inside the soil to be sampled and collected can be removed, so that after the collection device 4 is operated, the soil falling from the entire device no longer contains sand and gravel, thereby facilitating subsequent soil detection work;

[0054] After the soil to be sampled is impacted to make it soft, the soil can be excavated by setting up the collection device 4, so as to collect the sand and gravel in the soil. During operation, the operator turns on the rotating motor 42, and the rotating motor 42 starts to work, which will drive the rotating column 43 to rotate. During the rotation of the rotating column 43, the spiral plate 44 will excavate the soil and drive the soil and sand and gravel to move upward. By setting up the sand and gravel separation device 5, the sand and gravel in the soil can be separated, thereby facilitating the collection of sand and gravel. During operation, under the action of the spiral plate 44, the soil and sand and gravel will be driven to move upward. During the upward movement, the sand and gravel and soil will collide with the second separation plate. 55. Since the second separation plates 55 are arranged relatively densely, the sand and gravel will be retained on the upper surface of the second separation plates 55, while the soil will fall back to the surface. The separated sand and gravel will move upward again under the action of the spiral plate 44 and hit the first separation plate 53 again, thereby achieving a secondary separation of the sand and gravel from the soil. By separating and collecting the sand and gravel in the soil, the sand and gravel above and inside the soil to be sampled and collected are removed, so that the soil falling from the entire device after the collection device 4 is completed no longer contains sand and gravel. At this time, the fallen soil is directly collected by the external collection box to complete the soil collection operation, reducing the impact of the sand and gravel inside the soil on the detection, and facilitating the detection of soil pollution components.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention.
