Description

Technical Field

[0001] The present invention relates to a sampling device for soil monitoring, and particularly to a technology for facilitating rapid sampling of soils at different depths. Background Art

[0002] Soil monitoring refers to the activity of continuously observing and analyzing the physical, chemical, biological and other characteristics of soil and the soil environmental quality in the long term, so as to master the soil quality status and its changing trend, and provide a scientific basis for soil resource protection, rational utilization, pollution prevention and ecological environment management, etc.

[0003] In soil monitoring, the first step is to carry out reasonable sampling work, which requires selecting a suitable location and using appropriate tools to complete the sampling. The traditional sampling method is to take a certain amount of soil samples in a specific area, which can be surface soil or sampling after excavation. The specific sampling depth depends on the needs. For example, for soil metal ion analysis, soil planting situation analysis or deep-layer soil analysis, different-depth samples need to be taken for different purposes.

[0004] However, in the prior art, when it is necessary to excavate and sample the soil, the existing methods cannot achieve rapid integrated operation, especially a tool that can realize the excavation and sampling actions, and it is difficult to sample at a specific depth. It is impossible to quickly obtain soils at different depths after drilling, which is not conducive to the analysis of the soil. Summary of the Invention

[0005] To solve the problems existing in the above technologies, the present invention provides a sampling device for soil environmental monitoring, which includes a horizontal support block, a drilling outer cylinder and a sampling inner cylinder;

[0008] The sampling inner cylinder is slidably arranged inside the hollow cylinder structure. The sampling inner cylinder has a top lifting handle, and inside the sampling inner cylinder, there are a fixing rod, a left elastic sheet, a right elastic sheet, a left sampling cylinder and a right sampling cylinder. The upper ends of the left elastic sheet and the right elastic sheet are connected and arranged on the fixing rod. The lower end of the left elastic sheet is provided with the left sampling cylinder, and the lower end of the right elastic sheet is provided with the right sampling cylinder.

[0010] Preferably, the outer ends of the left placing cylinder and the right placing cylinder have guiding conical slopes to facilitate the engagement or disengagement of the left placing cylinder and the right placing cylinder with the sampling opening.

[0011] Preferably, a rotating brush is provided at the position of the sampling opening. The surface of the rotating brush has brush hairs. When the rotating brush acts, the soil on the side is brought into the sampling test tube inside the sampling opening.

[0012] Preferably, it further includes an arranging component. The arranging component includes a moving block, a bracket and a clamping member. The moving block is movably arranged in the track of the horizontal support block. The bracket is fixedly arranged on the moving block. The clamping member is arranged on the bracket. The clamping member has holding rods arranged crosswise. The ends of the holding rods have clamping hooks. The two holding rods are connected by a spring.

[0016] Put a sampling test tube into the sampling inner cylinder, put the sampling inner cylinder into the hollow cylinder structure, manually control the sampling inner cylinder to move to a specific height, so that the left sampling cylinder and the right sampling cylinder correspond to the sampling opening at the specific height position, and the soil at the specific height enters into the sampling test tube to complete soil sampling.

[0017] Preferably, the sampling inner cylinder slides vertically along the guiding sliding groove to achieve the purpose of guiding cooperation and avoid dislocation caused by vertical sliding.

[0018] Preferably, the rotating brush rotates to send the soil on the side into the sampling test tube.

[0019] Preferably, after the soil sampling is completed, the sampling inner cylinder moves to a specific height so that the sampling test tube corresponds to the placement component in the horizontal position. By moving the moving block, the clamping member approaches the sampling test tube, and the clamping hook can enter the port position of the sampling test tube. Then, manually hold and press the holding rod to compress the spring, so that the clamping hook clamps the sampling test tube to complete the extraction action.

Specific embodiments

[0030] First embodiment:

[0031] As Figures 1 to 3 shown, the present invention provides a sampling device for soil environment monitoring, which includes a horizontal support block 10, a drilling outer cylinder 20 and a sampling inner cylinder 30;

[0032] The horizontal support block 10 is used to support and place at the sampling position, and the middle part of the horizontal support block 10 has a through hole 11;

[0033] The drilling outer cylinder 20 has a hollow cylinder structure 21, the outer surface of the hollow cylinder structure 21 has an auger blade 22, the top of the hollow cylinder has a rotating handle 23, and the cylinder wall of the hollow cylinder structure 21 has sampling openings 24 at different heights;

[0034] The sampling inner cylinder 30 is slidably arranged inside the hollow cylinder structure 21, the sampling inner cylinder 30 has a top lifting handle 31, and the inside of the sampling inner cylinder 30 has a fixed rod 32, a left elastic sheet 33, a right elastic sheet 34, a left sampling cylinder 35 and a right sampling cylinder 36. The upper ends of the left elastic sheet 33 and the right elastic sheet 34 are connected and arranged on the fixed rod 32. The lower end of the left elastic sheet 33 is provided with the left sampling cylinder 35, and the lower end of the right elastic sheet 34 is provided with the right sampling cylinder 36. The left sampling cylinder 35 and the right sampling cylinder 36 can be engaged into the sampling opening 24; Sampling test tubes can be detachably placed in the left sampling cylinder 35 and the right sampling cylinder 36.

[0035] The application method of the sampling device for soil environment monitoring of the present invention includes the following steps:

[0036] Place the horizontal support block 10 on the ground, manually control the rotation of the rotary handle 23 and press it to make the drilling outer cylinder 20 enter the soil interior, and make the drilling outer cylinder 20 enter the required depth position as needed; that is, under the rotation and pressing actions, the drilling outer cylinder 20 excavates the soil and gradually moves downward, and it can stop when reaching the required depth. It is especially suitable for soft soil.

[0037] Put the sampling test tube into the sampling inner cylinder 30, place the sampling inner cylinder 30 into the hollow cylinder structure 21, manually control the movement of the sampling inner cylinder 30 to a specific height, so that the left sampling cylinder 35 and the right sampling cylinder 36 correspond to the sampling openings 24 at the specific height position, and the soil at the specific height enters the sampling test tube to complete soil sampling.

[0038] The sampling inner cylinder 30 gradually penetrates into the interior of the drilling outer cylinder 20. At the initial position, the left elastic piece 33 and the right elastic piece 34 are in a contracted state. At this time, the left elastic piece 33 and the right elastic piece 34 are compressed and fit on the inner wall of the cylinder body of the drilling outer cylinder 20. Then when moving to the sampling opening 24, due to elasticity, the left elastic piece 33 and the right elastic piece 34 force the left sampling cylinder 35 and the right sampling cylinder 36 connected on both sides to be engaged with the sampling opening 24, so that the sampling test tube can fit to the soil surface on the side, and the soil can enter the sampling test tube.

[0039] Preferably, the left sampling cylinder 35 and the right sampling cylinder 36 can be placed obliquely, that is, the port position (close to the outside) is upward, so that the sampling test tube is arranged obliquely. On the one hand, this is convenient for sampling, and on the other hand, it avoids soil leakage from the test tube.

[0040] When the sampling is completed and the test tube needs to be replaced, then pull the top lifting handle 31 to overcome the engagement relationship between the left sampling cylinder 35 and the right sampling cylinder 36 in the sampling opening 24, and the left elastic piece 33 and the right elastic piece 34 are compressed again to achieve the separation action, thus achieving the purpose of separating the two.

[0041] Second Embodiment:

[0042] As Figures 3 to 7 shown, preferably, a guiding chute 41 is provided inside the cylinder wall of the drilling outer cylinder 20, and a part of the left sampling cylinder 35 and the right sampling cylinder 36 is slidably fitted into the guiding chute 41. Through the setting of the guiding chute, it is beneficial for the sampling inner cylinder 30 to be smoothly placed into the drilling outer cylinder 20 and avoid dislocation.

[0043] Preferably, the outer ends of the left placing cylinder and the right placing cylinder have guiding tapered slopes 101 to facilitate the engagement or disengagement of the left placing cylinder 35 and the right placing cylinder 36 with the sampling opening 24.

[0044] Preferably, a rotary brush 51 is provided at the position of the sampling opening 24. The surface of the rotary brush 51 has brush hairs. When the rotary brush 51 operates, the soil on the side is brought into the sampling test tube inside the sampling opening. Preferably, the rotary brush 51 is controlled to rotate by a motor, and hard blades and soft brushes are distributed at intervals on the circumferential surface of the rotary brush 51, so that the soil on the side can be scraped, and more soil can enter the test tube through the rotation of the brush and the blade, as Figure 8 shown. According to requirements, the size or angular position of the rotary brush 51 can be adjusted so that the soil can more easily enter the sampling test tube. In addition, in other embodiments, the rotary brush 51 can be arranged on a telescopic structure, that is, the rotary brush 51 (driven by a motor to rotate) is driven by the telescopic structure (horizontal telescoping or vertical telescoping, or a combination of both) to perform telescopic movement to adjust the proximity to or away from the side soil surface, so as to better sweep the soil in.

[0045] Preferably, a sorting component 60 is further included. The sorting component 60 includes a moving block 61, a bracket 62 and a clamping member 70. The moving block 61 is movably arranged in the track 63 of the horizontal support block 10. The moving mode of the moving block 61 in the track 63 is, for example, manually driven or electrically driven. When electrically driven, an electrically driven moving wheel is used to move in the track 63, or other existing linear driving methods are used to drive the moving block in the track 63.

[0046] The bracket 62 is fixedly arranged on the moving block 61, and the clamping member 70 is arranged on the bracket 62. The clamping member 70 has holding rods 71 arranged in a cross shape. The ends of the holding rods 71 have clamping hooks 72. The two holding rods 71 are connected by a spring 73. The middle parts of the two holding rods 71 are hinged on a connecting rod 74, and the connecting rod 74 is arranged on the bracket 62.

[0047] Preferably, the connecting rod 74 is slidably arranged vertically on the bracket 62. The bracket 62 has a guide groove 81 and a vertical lead screw 82, and the vertical lead screw 82 can drive the connecting rod 74 to move up and down. Through the arrangement of the vertical lead screw 82, the height of the connecting rod 74 can be adjusted to an appropriate height so that the clamping member 70 can just match the sampling opening at a specific height and be used to take out the sampling test tube inside.

[0048] Preferably, the sampling inner cylinder 30 slides vertically along the guide chute 41 for the purpose of guiding and matching to avoid dislocation caused by vertical sliding.

[0049] Preferably, the rotation of the rotary brush 51 is used to send the soil on the side into the sampling test tube.

[0050] Preferably, after soil sampling is completed, the inner sampling cylinder 30 is moved to a specific height so that the sampling test tube corresponds to the placement component 60 in the horizontal position. By moving the moving block 61, the clamping member 70 is moved closer to the sampling test tube, and the clamping hook can be clamped to the port position of the sampling test tube that can enter. Then, manually hold and press the holding rod 71 to compress the spring 73, so that the clamping hook 72 clamps the sampling test tube to complete the extraction action.

[0051] In a further preferred solution, rotary brushes are provided above and below the port of the sampling opening. Through the cooperation of the two, it is easier to sweep the side soil into the inner sampling test tube.
