Description

Technical Field

[0001] The present invention relates to the technical field of soil pollution control, and in particular to an environmentally friendly soil pollution control device. Background Art

[0002] Soil refers to the loose surface layer of the land surface that is fertile and capable of growing plants. Its thickness is generally around 2m. Pollutants generated by human activities enter the soil and accumulate to a certain extent, causing soil quality to deteriorate, and then causing certain indicators of crops to exceed national standards. This is called soil pollution. Soil pollutants can be roughly divided into two categories: inorganic pollutants and organic pollutants. Inorganic pollutants mainly include acids, alkalis, heavy metals, salts, compounds of radioactive elements cesium and strontium, compounds containing arsenic, selenium, and fluorine, etc.

[0003] The most important of these is soil pollution caused by sewage irrigation. The large-scale use of pesticides and chemical fertilizers has caused a decrease in soil organic matter content and soil compaction, which is also one of the sources of soil pollution. In addition to causing a decrease in soil quality, crop yield and quality, soil pollution is more serious because the soil has an enrichment effect on pollutants. Some highly toxic pollutants, such as mercury and cadmium, are enriched in crop fruits, causing poisoning when consumed by humans or livestock.

[0004] Before treating soil pollution, it is necessary to first take samples of the soil in the designated area and develop a corresponding treatment plan by testing the types and contents of pollutants in the soil samples.

[0005] When the sampling is completed and the drill tube is taken out of the ground, if the soil sample inside is loose, it may fall off, resulting in failure of the sampling operation.

[0006] Therefore, it is necessary to invent an environmentally friendly soil pollution control device to solve the above problems. Summary of the invention

[0101] The installation through hole 230 is provided to provide space for the installation of the scraping assembly 300. When the scraping assembly 300 rotates and opens, the installation through hole 230 is opened, so that the soil sample scraped by the scraping assembly 300 enters the interior of the sampling tube 210. When the scraping assembly 300 rotates and closes, the installation through hole 230 is blocked to prevent the soil from entering the interior of the sampling tube 210 when the hole is drilled downward.

[0109] The scraper 320 is arranged to contact the soil and cut and sample the soil while rotating, which facilitates the normal use of the device;

[0110] The sample receiving strip 330 is opened when the blocking plate 310 rotates, and the sample receiving strip 330 is tilted to receive the soil scraped by the scraper 320 and guide it into the interior of the sampling tube 210 .

[0111] In some embodiments of the present invention, the push-open assembly 340 includes:

[0112] A polygonal sleeve 341, which is slidably sleeved on the outer side of the polygonal column 120;

[0118] The first hinge joint 342 and the second hinge joint 343 are matched to ensure the normal installation and use of the swing plate 344. When the first hinge joint 342 and the second hinge joint 343 rotate relative to each other, the swing plate 344 is pulled to rotate, so that the swing plate 344 drives the blocking plate 310 to open or retract.

[0150] The motor 810 drives the first gear 820 to rotate;

[0151] The first gear 820 and the second gear 830 are matched to each other so that when the first gear 820 rotates, the polygonal column 120 is driven to rotate synchronously.

[0152] Working method of the present invention:

[0153] When drilling, start the reduction motor (the reduction motor is not shown in the figure, and the output end of the reduction motor is connected to the threaded rod 720 to drive the threaded rod 720 to rotate) and the motor 810, so that the reduction motor drives the threaded rod 720 to rotate, so that the threaded rod 720 drives the lifting plate 740 to descend through the thread when rotating, so that the lifting plate 740 drives the polygonal column 120 and the motor 810 to descend synchronously;

[0154] When the motor 810 is started, it will drive the first gear 820 to rotate, so that the first gear 820 drives the polygonal column 120 to rotate through the second gear 830, so that the polygonal column 120 drives the drill bit 110 and the polygonal sleeve 341 to rotate, and at the same time, a blocking head is arranged between the sampling tube 210 and the polygonal column 120, and the sampling tube 210 is driven to rotate after the polygonal column 120 rotates a certain angle, and at the same time, after the swing plate 344 drives the scraper 320 to contact the sampling tube 210, it will drive the sampling tube 210 to rotate synchronously, so that the sampling tube 210 drives the blocking tube 410 to rotate synchronously through the driving head 250 and the guide channel 430, and the soil is rotated under the rotation of the blocking tube 410 and the drill bit 110;

[0155] When the soil hole rotation is completed, the polygonal column 120 is driven to rotate in the opposite direction. Since the blocking plate 310 and the scraper 320 are blocked by the blocking cylinder 410, and the friction between the spiral blade 420 and the soil is relatively large, the spiral blade 420 and the blocking cylinder 410 can rotate relative to the sampling cylinder 210. When the polygonal column 120 rotates in the opposite direction, the sampling cylinder 210 and the driving head 250 are driven to rotate, and the driving head 250 is rotated from the horizontal position 432 to the vertical position 431, and the elastic force of the compression spring 530 is released, so that the compression spring 530 pushes the sampling cylinder 210 to descend, and drives the blocking cylinder 410 to rise through the pull rope 600 when descending, and moves the corresponding The soil at a certain height is lifted, and the blocking plate 310 is staggered with the blocking cylinder 410. The swing plate 344 is pushed by the rotation of the polygonal column 120, so that the swing plate 344 pushes the blocking plate 310 to open. A sample receiving cloth strip 330 can also be arranged above the blocking plate 310 to prevent the soil falling from above from entering the sampling cylinder 210, and the mounting through hole 230 is opened, so that the scraper 320 contacts the soil, and scrapes the soil off during rotation and introduces it into the interior of the sampling cylinder 210 through the sample receiving cloth strip 330. After the sampling is completed, the polygonal column 120 is rotated forward, so that the polygonal column 120 drives the blocking plate 310 through the swing plate 344 to close the mounting through hole 230.

[0156] After sampling is completed, the blocking cylinder 410 is slid downward so that the blocking cylinder 410 drives the sampling cylinder 210 to rise and compress the compression spring 530. When the driving head 250 corresponds to the horizontal part 432, the blocking cylinder 410 is rotated so that the driving head 250 rotates to the inside of the horizontal part 432.
