Description

Technical Field

[0001] The 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 the plant dies, it is decomposed by microorganisms and soil animals. In a humid environment or a waterlogged environment, due to the lack of oxygen, the number of aerobic microorganisms decreases, which slows the decomposition of dead plant bodies and forms an accumulation of organic matter. These accumulated organic matter is called peat, also known as grass carbon or peat. Under natural conditions, the production and storage of organic matter is far greater than the decomposition. 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, technicians 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 arranged 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 is rotated through a soil storage tube, a connecting cover, a sampling tube, drill teeth and a sampling groove, and the soil to be sampled enters the sampling tube, and then 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 drives the soil sampling mechanism to move up and down through the cooperation of the inner thread sleeve and the rotating bearing, which is convenient for drilling the soil. However, the soil in the peat swamp wetland is relatively soft and contains a lot of water. If the soil is drilled by the soil sampling mechanism, it cannot guarantee that the soil depth in the soil sampling mechanism remains unchanged, thus affecting the sampling accuracy.

[0006] 2. The above soil sampling equipment for soil pollution treatment rotates the sampling pipe, and the soil to be sampled enters the sampling pipe. 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 pipe extracts a sample once, it is necessary to clean the sampling pipe to prevent contamination of the next sample. Moreover, during sampling, it is usually in the wild environment, making it inconvenient to clean the sample pipe.

[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

[0055] Embodiment three:

[0056] Reference Figure 8As shown, on the basis of the first and second embodiments, in order to reduce the weight of the storage cylinder 41 and the storage cover 411 when they are taken out, the soil in the storage cylinder 41 and the storage cover 411 and the water contained in the soil 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, and 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 tube 41, and the moisture in the soil in the storage tube 41 can enter the moving tube 40 through the transmission holes 50; a clean cavity 51 is formed between the bottom of the moving tube 40 and the inner wall of the sampling tube 30, and a hollow round cake 52 is provided at the bottom of the moving tube 40 to abut against the inner wall of the sampling tube 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 cavity 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 that the soil in the storage cylinder 41 and the storage cover 411 and the moisture contained in the soil are separated and collected, 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 moving tube 40, and the moving tube 40 can drive the hollow cake 52 to move downward when moving, so that the space in the cleaning chamber 51 is reduced and the pressure is increased, so that the water in the cleaning chamber 51 enters the hollow cake 52 through the circular hole 53, and the water in the hollow cake 52 enters the moving tube 40. The water in the moving 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 the 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 bottom plate 1 to move to the soil surface with sampling under the drive of the slide 10. In this process, the arc 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 fixing 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 fixing 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, so as to realize 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 disc 24 to rotate together. When the rotating disc 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 enter the cylinder 20 through the arc groove 37. 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 rotates and is inserted into the soil of the corresponding depth. Then the arc sampling plate 34 continues to rotate to send the soil into the sampling tube 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 reduce the labor intensity of the staff and improve the accuracy of the soil sampling depth; when the sampling is completed, the sampling tube 30 moves upward under the action of the spring 1 31, and the movement of the sampling tube 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, so as to prevent the soil from entering the cylinder 20 and polluting 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 tube 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 tube 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 content of the peat swamp wetland soil. The soil sample in the storage tube 41 and the storage cover 411 is then taken out of the material tube by moving the tube 40. In this process, the locking bolt 481 is rotated to rotate the locking piece 48, so that the adjusting ring 43 can rotate. When the adjusting ring 43 rotates, the L-shaped adjusting rod 44 can be driven to rotate together. When the L-shaped adjusting rod 44 rotates, the block 46 can be driven to move together, so that the block 46 is moved out of the slot 47. The storage cover 411 and the storage tube 41 are taken out of the sampling tube 30 by moving the tube 40, which is convenient for the operator to move the soil out of the storage cover 411 and the storage tube 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 moving tube 40, and when the moving tube 40 moves, it can drive the hollow cake 52 to move downward together, so that the space in the cleaning chamber 51 is reduced and the pressure is increased, 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 moving tube 40, and the water in the moving tube 40 will enter 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 the residual soil from contaminating the sample and improving the quality of sampling.
