Description

Technical Field

[0001] The present invention relates to the field of soil sampling, and in particular to a special sampling device and method for peat swamp wetland soil. Background Art

[0002] After plant death, it is decomposed by microorganisms and soil animals. In a humid environment or one with accumulated water on the surface, the lack of oxygen reduces the number of aerobic microorganisms, slowing the decomposition of dead plant bodies and leading to the accumulation of organic matter. These accumulated organic matter are called peat, also known as grass carbon or peat. Under natural conditions, the production and storage of organic matter far exceeds decomposition, and the land where peat accumulates is called peat swamp or peatland. Because peatlands have the characteristics of soft and elastic soil, high content of organic matter and humic acid, rich content of plant fiber, good ventilation and water permeability, and strong water holding capacity, traditional soil samplers are not applicable, and a special sampling device for peat swamp wetland soil is required.

[0003] However, there are usually some problems in the daily use of special sampling equipment for peat swamp wetland soil. With the development of science and technology, technical personnel in related fields have also carried out a lot of optimization on the special sampling equipment for peat swamp wetland soil to solve some problems that different consumer groups are concerned about. In order to make a more accurate comparison, a Chinese patent with publication number CN216144547U discloses a soil sampling equipment for soil pollution control, including a bottom plate, a roller movably connected to the bottom end of the bottom plate, a through groove provided inside the bottom plate, a telescopic rod fixedly connected to the top of the bottom plate, a connecting plate fixedly connected to the top of the telescopic rod, and a top frame fixedly connected to the top of the connecting plate. The soil sampling equipment for soil pollution control facilitates drilling of soil through a telescopic rod, a top frame, a driving motor, a sleeve, a soil sampling mechanism, a rotating shaft, a large gear, a small gear, an inner thread sleeve and a rotating bearing. The inner thread sleeve facilitates the connection and installation of the soil sampling mechanism, which is simple and efficient. The sampling tube, a connecting cover, a sampling tube, drill teeth and a sampling slot are passed through the sampling tube, and the soil to be sampled enters the sampling tube. Subsequently, the soil to be sampled can be taken out, thereby improving the accuracy of soil sampling.

[0004] However, the above-mentioned soil sampling equipment for soil pollution control still has the following shortcomings in actual use:

[0005] 1. The soil sampling equipment for soil pollution control mentioned above drives the soil sampling mechanism to move up and down through the cooperation of the internal threaded sleeve and the rotating bearing, making it convenient to drill the soil. However, the soil in peat swamp wetlands is relatively soft and contains a large amount of water. If the soil is drilled through the soil sampling mechanism, it cannot be guaranteed that the soil depth within the soil sampling mechanism remains unchanged, thereby affecting the sampling accuracy.

[0006] 2. The above soil sampling equipment for soil pollution control rotates the sampling tube, and the soil to be sampled enters the sampling tube. Subsequently, the soil to be sampled can be taken out, effectively improving the accuracy of soil sampling and solving the problem of reduced accuracy of the sampled soil. However, after the sampling tube extracts a sample once, the sampling tube needs to be cleaned to prevent contamination of the next sample. Moreover, when sampling, it is usually in a field environment, making it inconvenient to clean the sample tube.

[0007] Therefore, under the viewpoints stated above, there is still room for improvement in the existing special soil sampling equipment and methods for peat swamp wetlands. Summary of the Invention

When the storage cover 411 and the storage tube 41 are sealed, the operator pulls the moving tube 40 to drive the storage cover 411 and the storage tube 41 to move out of the sampling tube 30 together, so that the operator can move the soil out of the storage cover 411 and the storage tube 41.

The top of the mobile tube 40 is rotatably sleeved with an adjusting ring 43, and the adjusting ring 43 can rotate under the restriction of the mobile tube 40; the outer wall of the adjusting ring 43 is symmetrically provided with an L-shaped adjusting rod 44, and when the adjusting ring 43 rotates, it can drive the L-shaped adjusting rod 44 to rotate together; an L-shaped groove 45 is opened along the circumference of the sampling tube to limit the L-shaped adjusting rod 44, and the L-shaped adjusting rod 44 can move in the L-shaped groove 45; a block 46 is provided on the L-shaped adjusting rod 44, and the L-shaped adjusting rod 44 rotates When the adjusting ring 43 is rotated, the connecting rod 480 can be driven to rotate together, and when the connecting rod 480 is rotated, the locking plate 48 can be driven to rotate together; a locking bolt 481 is provided on the locking plate 48 through threaded cooperation, and the locking bolt 481 can be used to fix the locking plate 48, and when the locking plate 48 is fixed, the adjusting ring 43 can be fixed through the connecting rod 480.

[0054] During the specific implementation process, when it is necessary to move the sampling tube 30 downward through the moving tube 40, the locking bolt 481 is rotated to enable the locking plate 48 to rotate, and then the adjusting ring 43 is rotated. When the adjusting ring 43 rotates, it can drive the L-shaped adjusting rod 44 to rotate together. When the L-shaped adjusting rod 44 rotates, it can drive the block 46 to move together, so that the block 46 enters the slot 47, and then the locking bolt 481 is rotated again to fix the locking plate 48, so that the sampling tube 30 is moved together when the moving tube 40 moves; when it is necessary to remove the storage cover 411 and the storage tube 41 from the sampling tube 30 through the moving tube 40, the adjusting ring 43 is rotated to move the block 46 out of the slot 47, so that the storage cover 411 and the storage tube 41 are removed from the sampling tube 30 through the moving tube 40.

[0055] Example 3:

[0056] Reference Figure 8As shown, on the basis of embodiment 1 and embodiment 2, in order to reduce the weight of the storage cylinder 41 and the storage cover 411 when they are taken out, the soil and the water contained in the soil in the storage cylinder 41 and the storage cover 411 are separated and collected, and then after the sampling is completed, the storage cylinder 41 and the storage cover 411 can be cleaned by the collected water to prevent the residual soil from contaminating the sample and improve the quality of the sampling. In the specific embodiment of this scheme, a cleaning mechanism 5 is provided in the sampling cylinder 30; specifically, the cleaning mechanism 5 includes a transmission hole 50, a cleaning cavity 51, a hollow cake 52 and circular holes 53, transmission holes 50 are evenly opened along the circumference of the moving tube 40 and in the storage cylinder 41, and the moisture in the soil in the storage cylinder 41 can enter the moving tube 40 through the transmission holes 50; a clean chamber 51 is formed between the bottom of the moving tube 40 and the inner wall of the sampling cylinder 30, and a hollow round cake 52 is provided at the bottom of the moving tube 40 to contact the inner wall of the sampling cylinder 30, and the moisture in the moving tube 40 can enter the hollow round cake; a plurality of circular holes 53 are opened along the circumferential bottom of the hollow round cake 52, and the moisture in the hollow circular plate can enter the clean chamber 51 through the circular holes 53.

[0057] In a specific implementation, when the soil enters the storage cylinder 41, the moisture in the soil will enter the mobile tube 40 through the transmission hole 50, the moisture in the mobile tube 40 can enter the hollow cake 52, and the moisture in the hollow cake 52 can enter the cleaning chamber 51 through the circular hole 53, so as to separate and collect the soil in the storage cylinder 41 and the storage cover 411 and the moisture contained in the soil, thereby reducing the weight of the storage cylinder 41 and the storage cover 411 when they are taken out; after the soil in the storage cylinder 41 is taken out, the storage cylinder 41 and the storage cover 411 need to be cleaned, and the operation The operator presses the movable tube 40, and when the movable tube 40 moves, it can drive the hollow cake 52 to move downward together, thereby reducing the space in the cleaning chamber 51 and increasing the pressure, so that the water in the cleaning chamber 51 will enter the hollow cake 52 through the circular hole 53, and the water in the hollow cake 52 will enter the movable tube 40. The water in the movable tube 40 enters the storage cylinder 41 and the storage cover 411 through the transmission hole 50, so that the storage cylinder 41 and the storage cover 411 are cleaned by the collected water, preventing residual soil from contaminating the sample and improving the quality of sampling.

[0058] In addition, the present invention also provides a special sampling method for peat swamp wetland soil, comprising the following steps:

[0059] Step 1: The operator pushes the handle 13 to push the base plate 1 to move to the soil surface with sampling under the drive of the slide 10. During this process, the arc-shaped pressure plate 12 can bend the plants growing on the peat swamp wetland to prevent the plants from affecting the movement of the device and reduce the impact of the device on the peat swamp wetland ecology.

[0060] Step 2: When it moves to the location where sampling is to be performed, when the driving motor 25 rotates, it can drive the U-shaped plate 23 to rotate together. When the U-shaped plate 23 rotates, it can drive the cylinder 20 to rotate together through the arc plate 21. When the cylinder 20 rotates, it can move downward under the restriction of the fixed plate 14 and the bottom plate 1. When the cylinder 20 moves, it can drive the driving motor 25 to move together. When the driving motor 25 moves, it can drive the T-shaped slider 27 to move under the restriction of the T-shaped through groove 28. When the cylinder 20 rotates, it can move under the restriction of the fixed plate 14 and the bottom plate 1. When the cylinder 20 rotates, it can drive the conical drill bit 201 to rotate together, and drill holes in the soil through the conical drill bit 201. When the cylinder 20 rotates, it can also drive the cutting ring 202 to rotate together, and cut the plant roots in the soil through the cutting ring 202 to prevent the plant roots from obstructing the drilling. It realizes drilling on the soil to be sampled according to the sampling depth and cutting the plant roots on the path during drilling to prevent the plant roots from obstructing the drilling; after the drilling is completed, the operator rotates the cylindrical handrail 240, and the cylindrical handrail 240 can drive the rotating disk 24 to rotate together. When the rotating disk 24 rotates, it can drive the rotating shaft 22 to rotate together. When the rotating shaft rotates and drives the U-shaped plate 23 to rotate together, it can drive the driving motor 25 to rotate together, preventing the U-shaped plate 23 and the driving motor 25 from obstructing the next sampling step.

[0061] Step 3: After the drilling is completed, the operator presses the moving tube 40. When the moving tube 40 moves, it can drive the sampling tube 30 to move downward. When the sampling tube 30 moves downward, it can drive the support plate 32 to move downward together. When the support plate 32 moves downward, it can drive the synchronous rod 386 to move downward together. When the synchronous rod 386 moves, it can drive the bar block 382 to move together. When the bar block 382 moves, it drives the fender 380 to move upward through the steel cable 385, so that the soil can pass through the arc groove 37 and enter the cylinder 20. At the same time, when the sampling tube 30 slides under the restriction of the cylinder 20, it can also drive the support plate 32 to move together. When the support plate 32 moves, it can drive the rotating shaft 33 to move together. When the rotating shaft 33 moves, it can drive the arc sampling plate 34 to move together under the restriction of the limit groove 36. Then, when the arc sampling plate 34 moves into the arc groove 37, it can rotate The movable shaft 33 rotates under the restriction of the movable shaft 33, and the arc sampling plate 34 is inserted into the soil of the corresponding depth when it rotates. Then the arc sampling plate 34 continues to rotate to send the soil into the sampling cylinder 30 through the arc groove 37 and the sampling groove 35, so as to sample the soil of different depths in the peat swamp, greatly reducing the labor intensity of the staff and improving the accuracy of the soil sampling depth; when the sampling is completed, the sampling cylinder 30 moves upward under the action of the spring 1 31, and the movement of the sampling cylinder 30 can drive the support plate 32 to move together. When the support plate 32 moves, the strip plate moves upward under the action of the spring 2 383, and when the strip block 382 moves, the fender 380 is driven downward by the steel cable 385, so that the soil cannot enter the cylinder 20 through the arc groove 37, thereby preventing the soil from entering the cylinder 20 and contaminating the inner wall of the cylinder 20 when the cylinder 20 moves upward.

[0062] Step 4: After the soil on the arc-shaped sampling plate 34 passes through the sampling slot 35 and the groove 410 and enters the storage cylinder 41, the operator drives the rotating block 42 to rotate together by rotating the moving tube 40. When the moving block rotates, it can drive the storage cover 411 to rotate together. When the storage cover 411 rotates, it can drive the closing plate 412 to rotate together, so that the closing plate 412 enters the groove 410, and then the storage cover 411 and the storage cylinder 41 are sealed. In the process of sampling, soils of different depths are stored separately to prevent the soil from collapsing after sampling due to the softness and moisture of the peat swamp wetland soil. The soil sample in the storage cylinder 41 and the storage cover 411 is then taken out of the material cylinder by moving the tube 40. During this process, the locking bolt 481 is rotated to rotate the locking piece 48, thereby rotating the adjusting ring 43. When the adjusting ring 43 rotates, the L-shaped adjusting rod 44 is driven to rotate together. When the L-shaped adjusting rod 44 rotates, the block 46 is driven to move together, so that the block 46 is moved out of the slot 47. The storage cover 411 and the storage cylinder 41 are taken out of the sampling cylinder 30 by moving the tube 40, which is convenient for the operator to remove the soil from the storage cover 411 and the storage cylinder 41.

[0063] Step 5: After the soil enters the storage cylinder 41, the moisture in the soil will enter the mobile tube 40 through the transmission hole 50, the moisture in the mobile tube 40 can enter the hollow cake 52, and the moisture in the hollow cake 52 can enter the cleaning chamber 51 through the circular hole 53, so as to separate and collect the soil in the storage cylinder 41 and the storage cover 411 and the moisture contained in the soil, thereby reducing the weight of the storage cylinder 41 and the storage cover 411 when they are taken out; after the soil in the storage cylinder 41 is taken out, the storage cylinder 41 and the storage cover 411 need to be cleaned, and the operator The staff presses the movable tube 40, and when the movable tube 40 moves, it can drive the hollow cake 52 to move downward together, thereby reducing the space in the cleaning chamber 51 and increasing the pressure, so that the water in the cleaning chamber 51 will enter the hollow cake 52 through the circular hole 53, and the water in the hollow cake 52 will enter the movable tube 40. The water in the movable tube 40 enters the storage cylinder 41 and the storage cover 411 through the transmission hole 50, so that the storage cylinder 41 and the storage cover 411 are cleaned by the collected water, thereby preventing residual soil from contaminating the sample and improving the quality of sampling.
