[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] like Figures 1 to 5 As shown, this utility model provides a rapid soil solvent extraction instrument, including a housing 1. The housing 1 has a sliding groove 2 inside, and a slider 3 is slidably connected inside the sliding groove 2. A support plate 4 is fixedly installed inside the slider 3. A reaction chamber 5 is inserted into the support plate 4. A limit ring 6 is fixedly installed on the outside of the reaction chamber 5. A connecting rod 26 is snapped into the bottom of the support plate 4. A docking plate 27 is fixedly installed at the bottom of the connecting rod 26. A sealing chamber 28 is fixedly installed above the docking plate 27. The bottom of the reaction chamber 5 is located inside the sealing chamber 28.
[0021] When extraction is required, all moisture inside the soil is first removed, and soil particles are placed inside the reaction chamber 5. Then, the reaction chamber 5 is inserted into the support plate 4, and the limiting ring 6 limits the reaction chamber 5 to prevent it from falling off. After the bottom of the reaction chamber 5 is inserted into the sealing chamber 28, the sealing chamber 28 seals the bottom of the reaction chamber 5. Then, the extraction solvent is poured into the reaction chamber 5 to mix with the soil. After fusion, the extracted solvent has an accurate effect.
[0022] Among them, a cylinder 12 is fixedly installed on the top of the housing 1, an output shaft 13 is fixedly installed on the output end of the cylinder 12, a positioning plate 14 is fixedly installed on the bottom of the output shaft 13, a connecting shaft 15 is fixedly installed on the bottom of the positioning plate 14, and a piston 16 is fixedly installed on the bottom of the connecting shaft 15. The piston 16 is slidably connected inside the connecting shaft 15.
[0023] After the solvent and soil are placed inside the reaction chamber 5, the support plate 4 is installed inside the housing 1 by the sliding action of the slider 3 and the groove 2. After reaching the designated position, the cylinder 12 is activated to drive the positioning plate 14 downward through the output shaft 13, so that the connecting shaft 15 drives the piston 16 into the interior of the reaction chamber 5, keeping the interior of the reaction chamber 5 completely sealed. At this time, the support plate 4 heats the outside of the reaction chamber 5, while the piston 16 continues to move downward to pressurize the solvent and soil inside the reaction chamber 5, so that they are fully mixed, thereby increasing the extraction efficiency.
[0024] The bracket plate 4 has a sliding groove 7 inside, and a slider 8 is slidably connected inside the sliding groove 7. A limit rod 9 is fixedly installed above the slider 8. A connecting plate 10 is fixedly installed inside the limit rod 9. A bolt 11 is engaged inside the connecting plate 10 and engages with the bracket plate 4.
[0025] When the piston 16 is driven by the connecting shaft 15 to pressurize the interior of the reaction chamber 5, the limiting rod 9 is installed through the sliding action of the slider 2 8 and the sliding groove 2 7, and then fixed by the engagement of the bolts 11 with the connecting plate 10 and the bracket plate 4 respectively. At the same time, since the limiting rod 9 is located above the limiting ring 6 and limits the limiting ring 6, when the piston 16 moves up and down inside the reaction chamber 5 to fully mix the soil and solvent, it has the effect of maintaining the stability of the device and preventing the solvent from leaking out due to shaking.
[0026] The housing 1 has a sliding groove 17 inside, and a slider 18 is slidably connected inside the sliding groove 17. The inner side of the slider 18 is fixedly connected to the positioning plate 14.
[0027] When the starting cylinder 12 drives the positioning plate 14 to move up and down through the output shaft 13, the positioning plate 14 also moves up and down through the sliding action of the slider 3 18 and the slide groove 3 17. Since there are four slide grooves 3 17 and four sliders 3 18, and the four slide grooves 3 17 and four sliders 3 18 are located on the left and right sides of the support plate 1 4 respectively, the positioning plate 14 will not wobble laterally when it moves up and down, thus achieving the effect of maintaining overall stability.
[0028] The box 1 has a sliding groove 19 inside, a slider 20 is slidably connected inside the sliding groove 19, a support plate 21 is fixedly installed inside the slider 20, a collection cup 22 is provided inside the support plate 21, and a limit ring 23 is fixedly installed on the outside of the collection cup 22, with the limit ring 23 located above the support plate 21.
[0029] After the solvent and soil inside the reaction chamber 5 are fused and extracted, the connecting rod 26 is removed from the bottom of the support plate 4, which drives the docking plate 27 to be disassembled. At this time, since the piston 16 is inside the reaction chamber 5, the internal pressure is kept balanced, and the solution will not fall out of the reaction chamber 5. Then, the cylinder 12 is started to drive the output shaft 13 and the positioning plate 14 to move upward. At the same time, since the connecting shaft 15 and the positioning plate 14 are fixedly connected, when the piston 16 is pulled upward and removed from the inside of the reaction chamber 5, it will easily drip down from the bottom of the reaction chamber 5 and be collected by the collection cup 22, achieving the effect of easy collection.
[0030] The box 1 has a slide rail 24 inside, and a door panel 25 is slidably connected inside the slide rail 24. There are multiple reaction chambers 5, and the multiple reaction chambers 5 are located inside the support plate 4.
[0031] There are multiple connecting shafts 15 and pistons 16, and multiple pistons 16 correspond to multiple reaction chambers 5 respectively. The main function is to extract multiple different types of soil at the same time without interfering with each other, thereby improving the extraction efficiency.
[0032] Working principle and usage process of this utility model:
[0033] First, all the moisture inside the soil is removed. Soil particles are placed inside the reaction chamber 5. Then, the reaction chamber 5 is inserted into the support plate 4. At the same time, the limiting ring 6 limits the reaction chamber 5 to prevent it from falling off. After the bottom of the reaction chamber 5 is inserted into the sealing chamber 28, the sealing chamber 28 seals the bottom of the reaction chamber 5. Then, the extraction solvent is poured into the reaction chamber 5 to mix with the soil.
[0034] Secondly, a reaction chamber 5 is inserted into the inside of the support plate 4, a limiting ring 6 is fixedly installed on the outside of the reaction chamber 5, a connecting rod 26 is snapped into the bottom of the support plate 4, a docking plate 27 is fixedly installed at the bottom of the connecting rod 26, and a sealing chamber 28 is fixedly installed above the docking plate 27. The bottom of the reaction chamber 5 is located inside the sealing chamber 28. When the solvent and soil are put into the inside of the reaction chamber 5, the support plate 4 is installed into the inside of the box 1 by the sliding action of the slider 3 and the slide groove 2. After reaching the designated position, the cylinder 12 is started to drive the positioning plate 14 to move downward through the output shaft 13, so that the connecting shaft 15 drives the piston 16 into the inside of the reaction chamber 5, so that the inside of the reaction chamber 5 is completely sealed. At this time, the support plate 4 heats the outside of the reaction chamber 5, and the piston 16 continues to move downward to pressurize the solvent and soil inside the reaction chamber 5, so that they are fully mixed, thereby increasing the extraction efficiency. It is simple to operate, the positions are all fixed, and it is difficult to make mistakes.
[0035] Meanwhile, since the inside of the housing 1 is provided with a sliding groove 17, and a slider 18 is slidably connected inside the sliding groove 17, and the inner side of the slider 18 is fixedly connected to the positioning plate 14, when the starting cylinder 12 drives the positioning plate 14 to move up and down through the output shaft 13, the positioning plate 14 also moves up and down through the sliding action of the slider 18 and the sliding groove 17. Since there are four sliding grooves 17 and four sliders 18, and the four sliding grooves 17 and four sliders 18 are located on the left and right sides of the support plate 4 respectively, the positioning plate 14 will not wobble laterally when it moves up and down, thus achieving the effect of maintaining the overall stability.
[0036] Finally, a groove 7 is provided inside the support plate 4. A slider 8 is slidably connected inside the groove 7. A limiting rod 9 is fixedly installed above the slider 8. A connecting plate 10 is fixedly installed inside the limiting rod 9, and a bolt 11 is engaged inside the connecting plate 10. The bolt 11 is engaged with the support plate 4. When the piston 16 is driven by the connecting shaft 15 to squeeze into the reaction chamber 5 to achieve the effect of pressurization, the limiting rod 9 is installed through the sliding action of the slider 8 and the groove 7. It is then fixed by the engagement of the bolt 11 with the connecting plate 10 and the support plate 4 respectively. Since the limiting rod 9 is located above the limiting ring 6 and limits the limiting ring 6, when the piston 16 moves up and down inside the reaction chamber 5 to fully mix the soil and solvent, it has the effect of maintaining the stability of the device and preventing the solvent from leaking due to shaking.
