Description

Technical Field

[0001] The invention relates to the technical field of soil prevention and control, in particular to a sample sampling and collecting device for soil environment prevention and control. Background Art

[0002] Soil management is a series of measures to protect, improve and control the soil, aiming to prevent soil degradation, pollution and disease, while improving soil quality and fertility to ensure the sustainable development of agricultural production and the health of the ecological environment.

[0003] Soil protection includes preventing soil erosion, desertification, salinization and other degradation phenomena through reasonable land use planning, soil and water conservation measures, vegetation restoration, etc. This helps to maintain the fertility and structure of the soil and provide a good growth environment for crops.

[0004] Soil improvement involves improving the physical, chemical and biological properties of soil and increasing soil fertility and productivity through agricultural management measures such as fertilization, irrigation and tillage. For example, the application of organic fertilizers can increase the organic matter content of the soil and improve the soil structure; reasonable irrigation can maintain the moisture balance of the soil and is conducive to the growth of crops.

[0005] The first step in soil prevention and control is to take samples and analyze the composition of soil pollutants. For shallow soil, sampling is usually done manually. The soil quality in different regions varies greatly, and sampling in drier areas is more laborious. Usually, the soil is directly pressed down to make it enter the sampler. When the soil is too hard to reach the predetermined depth, it is often necessary to turn the sampler left and right and move it slowly downward until the predetermined sampling depth is reached. This method will make the sample less intact and easier to break. Summary of the invention

[0015] Preferably, the adjustment component is surrounded by the outer shell and the cover plate to form a cylindrical installation structure; the left and right ends thereof extend outward to form a connection portion adapted to the handle;

[0016] A ratchet and two matching claws for limiting are arranged inside the adjustment component; the claws rotate around the rotating shaft, and an adjustment bolt is installed on the rotating shaft; the adjustment bolt extends upward and pushes out of the outer shell; the adjustment bolt is rotated to adjust the angle of the claw, control the position of the claw and the ratchet, and then control the ratchet to run or stop in the direction of movement.

[0017] Preferably, a worm, a worm wheel and a plurality of fasteners are also provided inside the adjustment component;

[0018] The worm wheel is fixedly installed with the cover plate, and a plurality of strip-shaped grooves are preset on the cover plate for matching with the fasteners for installation and limiting the range of motion of the fasteners; the worm is located on one side of the worm wheel and maintains matching transmission;

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example 1

[0036] This embodiment provides a soil environment control sample collection device, such as Figure 1 As shown, it includes a handle 1, a support member 2, an adjustment component 5 and a sampling component 4;

[0037] The handle 1 is a hard square tube structure, with a protective cushion layer wrapped on the outside to increase friction and prevent slipping during sampling; the sampling assembly 4 is installed at the bottom of the support 2; the top of the support 2 passes through the adjustment assembly 5 and remains fixed; the handle 1 is symmetrically arranged on the left and right sides of the adjustment assembly 5; the support 2 is a metal round tube, and the part where its end is connected to the adjustment assembly 5 is a regular quadrilateral or regular hexagonal prism. When the handle 1 is turned, the adjustment assembly 5 and the clamped support 2 rotate accordingly, and the sampling assembly 4 enters the soil in a rotating manner for sampling; the sample is clamped in the middle of the sampling assembly 4.

[0038] In this embodiment, the sampling assembly 4 includes two groups of symmetrically arranged side panels 41 and tapered portions 42; the side panels 41 extend downward from the bottom of the support 2; the tapered portion 42 is integrally formed with the downwardly extending portion of the side panels 41; the side panels 41 are arranged in an arc shape, and the curvature thereof is the same as the curvature of the outer circumference of the support 2; the side panels 41 and the tapered portion 42 are arranged obliquely relative to the support 2; the side panels 41 are deflected at a certain angle toward the center of the circle of the support 2. During the sampling process, the inclined sampling assembly 4 is easier to insert into the soil, and as the depth of insertion into the soil gradually increases, the sample taken gradually fills the entire sampling assembly 4, so that the inclined side panels 41 are gradually stretched open to form a shape such as Figure 7 Status shown.

[0039] In this embodiment, the adjustment assembly 5 is surrounded by an outer shell 51 and a cover plate 53 to form a cylindrical installation structure; the left and right ends thereof extend outward to form a connection portion adapted to the handle 1;

[0040] A ratchet 57 and two matching claws 58 for limiting are arranged inside the adjustment component 5; the claw 58 rotates around the rotating shaft, and the adjustment bolt 52 is installed on the rotating shaft; the adjustment bolt 52 extends upward and pushes out of the outer shell 51; the adjustment bolt 52 is rotated to adjust the angle of the claw 58, control the position of the claw 58 and the ratchet 57, and then control the ratchet 57 to run or stop in the direction of movement.

[0041] A worm 54, a worm wheel 56 and a plurality of fasteners 55 are also provided inside the adjustment assembly 5;

[0042] The worm wheel 56 is fixedly installed with the cover plate 53. The cover plate 53 is provided with a plurality of strip-shaped grooves for being installed in cooperation with the fastener 55 to limit the range of movement of the fastener 55. The worm 54 is located on one side of the worm wheel 56 and maintains cooperative transmission.

[0043] There are multiple fasteners 55, and they are staggered with each other; the fasteners 55 are inserted into the grooves of the cover plate 53 through the pins; after the multiple fasteners 55 are combined, the middle part is a regular polygonal clamping structure; the worm 54 is rotated to drive the worm wheel 56 to rotate, and the worm wheel 56 is connected to the cover plate 53; during the movement of the cover plate 53, the fasteners 55 are pulled to move by the pins, thereby controlling the opening size of the clamping structure to adapt to support members 2 with different interface shapes.

[0044] During operation, different types of supports 2 can be selected to be connected to the adjustment assembly 5 according to the specific requirements of the samples taken; the sizes of the interfaces at the tops of different supports 2 are different; at this time, the size of the opening of the snap-fit ​​structure can be adjusted by rotating the worm 54; specifically, the worm 54 is rotated to drive the worm wheel 56 to rotate, and the worm wheel 56 is connected to the cover plate 53; during the movement of the cover plate 53, the fastener 55 is pulled by the pin shaft to lock or unfold it, so as to adapt to different snap-fit ​​structures; after adjustment, the worm 54 can be locked by an external limiter to prevent shaking during use and cause the support 2 to fall off.

[0045] When sampling, insert the sampling assembly 4 downward into the soil with force. At this time, according to the user's usage habits, the angle of the claw 58 is adjusted by rotating the adjustment bolt 52 so that the left or right claw 58 is engaged with the ratchet 57, thereby controlling the ratchet 57 to run or stop in the direction of movement. For example, after the left claw 58 is locked, the right side remains open; at this time, when the handle 1 is turned clockwise, the claw 58 and the ratchet 57 keep rotating relative to each other, and the support 2 remains stationary; while when the handle 1 is turned counterclockwise, the claw 58 and the ratchet 57 remain locked, and the support 2 rotates with the handle 1; similarly, when the left claw 58 is opened and the right claw 58 is locked, when the handle 1 is turned clockwise, the claw 58 and the ratchet 57 remain locked, and the support 2 rotates with the handle 1; while when the handle 1 is turned counterclockwise, the claw 58 and the ratchet 57 keep rotating relative to each other, and the support 2 rotates with the handle 1. The support member 2 remains stationary; the user can choose a suitable force application method according to his / her habits; during the reciprocating rotation of the handle 1, the support member 2 always rotates in the same direction, thereby avoiding the shaking of the soil sampled inside, which is conducive to maintaining the integrity of the sample; in addition, the side plate 41 and the tapered portion 42 of the sampling component 4 are both inclined; the inclined structure and the tapered portion 42 make it easier for the sampling component 4 to be inserted into the soil. At the same time, as the depth of insertion into the soil gradually increases, the sample taken gradually fills the entire sampling component 4, so that the inclined side plate 41 is gradually opened to form a Figure 7 In the state shown, the sample is clamped, which is also beneficial to maintaining the integrity of the sample taken.

[0046] Example 2

[0047] The present embodiment provides a sample sampling and collection device for soil environment prevention and control. Unlike the embodiment 1, the present embodiment further includes an ejection assembly 3; the ejection assembly 3 includes a pressing plate 31, a connecting rod 32 and an extrusion plate 33; the connecting rod 32 passes through the support member 2 and extends downward to the sampling assembly 4; the extrusion plate 33 is installed at the end of the connecting rod 32 and is clamped with the side plate 41; during the downward movement of the extrusion plate 33, the side plate 41 is squeezed to push the side plate 41 open and squeeze the sample out of the sampling assembly 4; the pressing plate 31 is installed on the top of the connecting rod 32, and a distance greater than the movement is left between it and the outer shell 51 of the adjustment assembly 5; when the pressing plate 31 moves to the lowest point, it maintains a distance of more than 10 cm from the outer shell 51.

[0048] During use, the pressing plate 31 is first lifted up to be at the highest point of the stroke; and since the extrusion plate 33 at the bottom has a built-in magnet, it can maintain magnetic attraction with the bottom of the support 2, and the pressing plate 31 will not fall down when it is released, thereby forming an auxiliary fixing structure; at the same time, since the diameter of the extrusion plate 33 is slightly smaller than the diameter of the support 2, when it is at the highest point of the stroke, a structure such as Figure 6In the state shown, the inclined side plate 41 just presses against the squeezing plate 33, and the squeezing plate 33 remains in a relatively stable state. During the sampling process, the soil gradually fills the entire sampling assembly 4, and the inclined side plate 41 is gradually straightened; after the sampling is completed, hold the handle 1 to pull the entire device upward; then push the pressing plate 31 on the ejection assembly 3 downward, and the pressing plate 31 pushes the squeezing plate 33 downward through the connecting rod 32, squeezing out the sample in the sampling assembly 4, and obtaining a relatively complete soil sample. In this embodiment, the edges of the conical portion 42 and the side plate 41 can also be sharpened to make it easier to enter the soil.

[0049] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
