Description

Technical Field

[0001] The invention relates to the technical field of soil survey and sampling, in particular to a soil sampling device and a use method thereof. Background Art

[0002] Soil sampling refers to the method of collecting soil samples, including the layout of the sampling and sampling technology. The collection of profile soil samples should be carried out after the profile observation and recording is completed. Before sampling, the profile should be repaired and cleaned, and the top layer of loose soil should be scraped off. Then, samples should be taken from the central typical part layer by layer from top to bottom. The samples after sampling are heated and evaporated in the laboratory, and then analyzed after removing moisture.

[0003] When conducting quantitative soil sampling, a pressure handle is generally used to press a ring knife of a specific volume into the soil, and then the ring knife and the soil sample inside are sent to the laboratory for testing and analysis. After each sampling is completed, the ring knife and the soil sample must be stored and transported together. When a large number of samples need to be collected, a large number of ring knives need to be prepared. These metal ring knives are heavy and inconvenient to carry. The ring knives loaded with soil samples need to be stored separately, which is not convenient for transportation. In addition, the number of ring knives will also restrict the number of soil samples that can be collected, which is very restrictive when collecting large quantities of soil samples on a large scale.

[0034] A method for using a soil sampling device, comprising: When pushing material: The first push mode: Step S11: inserting the ring cutter 110 with the sample into the first docking inner ring groove 102; Step S12: Push the push rod 112 so that the push piston 111 pushes out the soil sample; The second push mode: Step S21: inserting the ring knife 110 with the sample into the protective tube 107; Step S22: docking the holding tube 101 with the protective tube 107; Step S23: Push the push rod 112, and the push piston 111 pushes out the soil sample; The third push mode: Step S31: Install the first connection seat 301 and the second connection seat 302 on the surface of the holding tube 101; Step S32: twisting the threaded column 507 to ensure that the tape roller 503 can rotate freely; Step S33: sleeve the return spring 408 on the surface of the push rod 112; Step S34: The cartridge 401 is fixedly sleeved on the top of the handle 113 and the return spring 408 is pressed. The return spring 408 pushes the cartridge 401 upward so that the push rod 112 drives the push piston 111 to return to its original position. Step S35: twisting the threaded column 507 to ensure that the tape roller 503 and the transmission cylinder 501 can be locked; Step S36: inserting the ring knife 110 with the sample into the protective tube 107; Step S37: docking the holding tube 101 with the protective tube 107; Step S38: repeatedly pulling and releasing the pulling ring 706 to push the material; When cleaning: Step U1: Connect the water storage bottle 201 filled with pure water to the docking cover 202; Step U2: inserting the ring knife 110 after taking out the sample into the second knife edge retaining groove 206; Step U3: retract the push rod 112 so that the push piston 111 slides out from the inside of the ring knife 110; Step U4: Start the water pump 204 for flushing.

[0035] Working principle: In the first pushing mode, the ring knife 110 with the sample is inserted into the first docking inner ring groove 102, ensuring that the blade is facing outward, and then the push rod 112 is pushed, and the push rod 112 pushes the pushing piston 111, and the pushing piston 111 gradually enters the ring knife 110 to push out the soil sample; In the second pushing mode, the ring knife 110 with the sample is inserted into the protective tube 107 so that the blade is aligned with the first blade retaining groove 109, and then the holding tube 101 is threaded or clamped with the protective tube 107, and the protective tube 107 and the holding tube 101 are held by hand, and then the push rod 112 is pushed, and the push rod 112 pushes the pushing piston 111, and the pushing piston 111 gradually enters the ring knife 110 to push out the soil sample; In the third pushing mode, the first connecting seat 301 and the second connecting seat 302 are fixedly installed on the surface of the holding tube 101 by means of bolts 303 and nuts 304, and then the threaded column 507 is twisted to make the extrusion piston 506 slide outward, and the rubber diaphragm 505 shrinks to ensure that the winding roller 503 can rotate freely, and then the return spring 408 is sleeved on the surface of the push rod 112, and then the pressure ring 405 is slid up to relax the bottom end of the cartridge 401, and the cartridge 401 is sleeved on the top of the handle 113 and the return spring 408 is pressed, and then the pressure ring 405 is slid down so that the pressure ring 405 is stuck on the surface of the block 404 to press the cartridge 401 tightly, so that the cartridge 401 fixes the handle 113, and at this time the return spring 408 squeezes the cartridge 401 , thereby driving the push rod 112 to slide up, and then driving the push piston 111 to slide up and reset, and then twisting the threaded column 507 to make the squeezing piston 506 slide inward, and the rubber diaphragm 505 expands, thereby squeezing the tape roller 503, ensuring that the tape roller 503 and the transmission cylinder 501 can rotate synchronously, and then insert the ring knife 110 with the sample into the protective cylinder 107, so that the blade and the first blade retaining groove 109 are aligned, and then the holding cylinder 101 is threaded or clamped with the protective cylinder 107, and the protective cylinder 107 and the holding cylinder 101 are held, and the pulling ring 706 is pulled. The pulling ring 706 drives the cable roller 703 to rotate through the pulling rope 705, and the cable roller 703 rotates through the transmission shaft 701. 8 is tightened, and at the same time, when the cable roller 703 rotates, it drives the second driving gear 702 to rotate through the transmission shaft 701, and the second driving gear 702 drives the second driven gear 604 to rotate and amplify the torque, and then the second driven gear 604 drives the shifting cylinder 603 to rotate through the first transmission shaft 601, and the shifting cylinder 603 drives the ratchet wheel 607 to drive the second transmission shaft 602 to rotate through the pawl 605, and then the pulling ring 706 is released, and the spiral spring 708 is released and drives the cable roller 703 through the transmission shaft 701 to rewind the pulling cable 705, and at the same time, the second driving gear 702, the first transmission shaft 601 and the second driven gear 604 are reversed, and then the pulling ring 706 is pulled again to make the second transmission shaft 602 rotate again. The second transmission shaft 602 rotates again, and the above-mentioned action is repeated to make the second transmission shaft 602 rotate intermittently. The second transmission shaft 602 is driven by the first driving gear 608 to drive the first driven gear 502 to rotate and amplify the torque. Then the first driven gear 502 drives the winding roller 503 to rewind through the transmission cylinder 501. The winding roller 503 rewinds the winding belt 504. The movable pulley structure formed between the winding belt 504, the winding roller 503, the support roller 306 and the guide roller 407 further saves effort, thereby pulling the reversing unit down, and the reversing unit drives the push rod 112 to descend. The push rod 112 pushes the pushing piston 111. The pushing piston 111 gradually enters the inside of the ring knife 110 to push out the soil sample, thereby ensuring that the hard soil sample is pushed out with effort. When cleaning, connect the water storage bottle 201 filled with pure water to the docking cover 202, insert the ring knife 110 after taking out the sample into the second blade retaining groove 206, ensure that the blade faces outward, then retract the push rod 112, so that the pushing piston 111 slides out from the inside of the ring knife 110, start the water pump 204, and the water pump 204 pressurizes and pumps the pure water inside the water storage bottle 201 outward. The water flows through the water guide hose 209, the water inlet pipe 208, the water pump 204 and the drain pipe 207 in turn, and then is sprayed out from the atomizing nozzle 211 in atomized form. The atomized water flow continuously rinses the inside of the ring knife 110 and the lower surface of the pushing piston 111, thereby ensuring that the ring knife 110 can be reused.
