Description

Technical Field

[0001] This invention relates to the field of soil research, specifically to a washing device for screening soil aggregates. Background Technology

[0002] Aggregates are the basic units of soil structure and the material basis for forming good soil structure. Their distribution characteristics are an important indicator reflecting the level of soil fertility. Usually, after treating the soil or mixing aggregates obtained by dry sieving in appropriate proportions, the mixture is sieved in water using a double sieve (wet sieving) to determine the quantity and distribution of water-stable aggregates.

[0003] The commonly used washing and screening devices at present require the screen to be completely immersed in water to ensure sufficient screening, which consumes a large amount of water. In addition, the relative flow velocity between the water and the soil is slow, and manual shaking is required to increase the relative flow velocity, which not only increases the difficulty of manual operation and the amount of labor, but also increases the cost.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship. Example

[0047] like Figure 1 and Figure 2As shown, the flushing device for screening soil aggregates includes: a cylinder 1, a fixed cylinder 2, a pressurizing unit, a mounting component 10, a water outlet pipe, and a water outlet control unit. The fixed cylinder 2 is installed at the center of the top of the cylinder 1. The fixed cylinder 2 is a hollow cylindrical structure with threads on its outer wall. The cylinder 1 has matching internal threads. The fixed cylinder 2 is fixedly connected to the cylinder 1 by screws, and a gasket is provided between them to increase sealing. The pressurizing unit is installed inside the fixed cylinder 2, and its bottom extends into the inner cavity of the cylinder 1. The cylinder 1 contains a flushing fluid; in this embodiment, clean water is used as the flushing fluid. A space is left between the clean water level and the top of the inner cavity of the cylinder 1, and the bottom of the pressurizing unit does not contact the water surface. The pressurizing unit is used to increase the air pressure in the space above the water surface. The mounting component 10 is installed at an eccentric position on the top of the cylinder 1. The mounting component 10 is a hollow cylinder, and its bottom end extends into the cylinder 1. The water outlet pipe is installed inside the mounting component 10, with its top end extending out of the top end of the mounting component 10 and its bottom end extending into the bottom end of the inner cavity of the cylinder 1. The water outlet control unit is installed at the top of the cylinder 1 and is used to control the opening and closing of the water outlet pipe.

[0048] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The pressurization unit includes: a pressurization cylinder 3, a piston rod 4, a handle 5, a first one-way valve 6, a second one-way valve 7, an air pipe 8, and an air port 9. The pressurization cylinder 3 is fixedly installed inside the fixed cylinder 2, and an air outlet is installed at the bottom end of the pressurization cylinder 3. The piston rod 4 is slidably installed inside the pressurization cylinder 3. The bottom of the piston rod 4 is a rubber piston, which fits tightly against the inner cavity of the pressurization cylinder 3, ensuring good airtightness. Its movement pushes the air inside the pressurization cylinder 3. The handle 5 is installed at the top of the piston rod 4. The first one-way valve 6 is installed at the air outlet at the bottom end of the pressurization cylinder 3 and is used to control the flow direction of the gas in the pressurization cylinder 3. In this embodiment, the first one-way valve 6 ensures that the air inside the pressurization cylinder 3 can flow towards the cylinder 1 and prevents reverse flow. The second one-way valve 7 is installed at the bottom end of the pressurization cylinder 3, and one side of the second one-way valve 7 communicates with the inner cavity of the pressurization cylinder 3. In this embodiment, the second one-way valve 7 ensures that air flows towards the pressurization cylinder 3 and prevents reverse flow. One end of the air tube 8 is connected to the other end of the second one-way valve 7. Air holes 9 are provided on the fixed cylinder 2 and the pressurizing cylinder 3, and the other end of the air tube 8 is connected to the air holes 9. It is noteworthy that a groove 201 is provided on the outer wall of the fixed cylinder 2 to accommodate the air tube 8, preventing the air tube 8 from interfering with the connection between the fixed cylinder 2 and the cylinder body 1. In this embodiment, both the first one-way valve 6 and the second one-way valve 7 are LCV one-way valves.

[0049] The actual working principle of the above structure is as follows: Water is injected into the cylinder 1 so that the liquid level is not higher than the preset height line. The fixed cylinder 2 is screwed on and fixed together with the pressurizing part. Pull the handle 5 upward so that the piston rod 4 moves upward along the axis of the pressurizing cylinder 3. Air enters the pressurizing cylinder 3 through the air hole 9-air pipe 8-second one-way valve 7. Then, press the handle 5 downward so that the air in the pressurizing cylinder 3 flows into the cylinder 1 through the first one-way valve 6, increasing the air pressure in the space above the liquid level in the cylinder 1.

[0050] The water outlet pipeline includes an inlet water pipe 11 and a outlet water pipe 12. The inlet water pipe 11 is installed at the top of the cylinder 1 and connected to the mounting component 10. The outlet water pipe 12 is installed at the bottom of the mounting component 10, and the bottom end of the outlet water pipe 12 extends to the bottom end of the inner cavity of the cylinder 1.

[0051] refer to Figure 2 , Figure 3 , Figure 5 As shown, the water outlet control unit includes: a control chamber 13, a baffle 14, a through hole 15, an extension rod 16, a rack 17, a rotating rod 18, a gear 19, and a torsion spring 20. The control chamber 13 is eccentrically mounted on the mounting member 10, and the two are connected internally. The baffle 14 is rotatably mounted inside the control chamber 13. Both the baffle 14 and the inner cavity of the control chamber 13 are circular and coaxial. The through hole 15 is located at an eccentric position on the baffle 14 and corresponds to the inner cavity of the mounting member 10. The extension rod 16 is mounted at the center of the bottom end of the baffle 14 and extends beyond the center of the bottom end of the control chamber 13. The rack 17 is connected to the extension rod 16 via the mounting rod. The rack 17 is arc-shaped and coaxial with the baffle 14. The rotating rod 18 is rotatably mounted on the cylinder 1, and the bottom end of the rotating rod 18 extends into the cylinder 1. Gear 19 is installed at the bottom of rotating rod 18 and meshes with rack 17, allowing them to rotate synchronously. Torsion spring 20 is sleeved on rotating rod 18, with its two ends fixedly connected to rotating rod 18 and outer wall of cylinder 1, respectively.

[0052] The actual working principle of the above structure is as follows: The pressure inside the cylinder 1 is increased by the pressurization unit. Then, the water inlet pipe 11 is aligned with the position to be rinsed. The rotating rod 18 is rotated, causing the gear 19 to rotate and drive the rack 17 to perform a circular motion. This causes the extension rod 16 and the baffle 14 to rotate together. When the through hole 15 is aligned with the mounting part 10, clean water is sprayed out by high pressure through the drain pipe 12-mounting part 10-water inlet pipe 11. During this process, the torsion spring 20 is forced to undergo elastic deformation. When the external force is removed, the torsion of the torsion spring 20 is used to reverse the rotating rod 18 to reset. Finally, the baffle 14 closes the clean water passage.

[0053] During use, the equipment is moved to the bottom of the screen, and a mist or jet nozzle is installed at the top of the water inlet pipe 11 as needed. This allows for upward spraying of the screen, using high-pressure water to separate soil aggregates, saving water and eliminating the need for manual sieving, thus saving labor. The outlet of the water inlet pipe 11 is aligned with the aggregate screen to rinse soil particles, evenly rinsing all parts of the screen from left to right. Then, the screen is rotated clockwise to rinse the inner wall, ensuring no soil particles remain. During use, the water pressure will gradually decrease; manual pressurization should be performed as needed. Each of the five screens should be manually pressurized at least 10-15 times.

[0054] Experimental results of this embodiment 1: The time required to flush soil aggregates (2 mm - 0.25 mm) includes flushing time and irrigation time. The average flushing time is 45 seconds. Two flushes require one irrigation. One irrigation is 4 L, and the average irrigation time is 15 seconds. The time required for four flushes plus two irrigations is 45 × 4 + 15 × 2 = 210 seconds. The average water volume required is 250 ml. The average volume of water-soil mixture received by flushing is 430 ml.

[0055] Experimental results 2 of this embodiment: The time required to flush soil aggregates (2 mm - 0.25 mm) includes flushing time and irrigation time. The average flushing time is 20 seconds, the average time required to irrigate 4 L once is 25 seconds, and the time required for four flushes plus one irrigation is 20 × 4 + 25 = 105 seconds; the average water volume required is 180 ml; the average volume of water-soil mixture received by flushing is 380 ml.

[0056] refer to Figure 1 and Figure 6The washing device for screening soil aggregates also includes a pressure relief mechanism, which is installed at the top of the cylinder 1. The pressure relief mechanism includes a fixed cylinder 21, a fixed plate 22, a pressure relief port 23, a pressure relief valve 24, a spring 25, and a side groove 26. The fixed cylinder 21 is installed on the upper surface of the cylinder 1 and communicates with the inner cavity of the cylinder 1. The fixed plate 22 is installed inside the fixed cylinder 21, and the pressure relief port 23 is located at the center of the fixed plate 22. The pressure relief valve 24 is installed inside the fixed cylinder 21 and moves vertically. The bottom of the pressure relief valve 24 is a rubber stopper, the shape of which, like the shape of the fixed plate 22, is an inverted frustum. Normally, the two fit together and are sized to fit. When the stopper fits with the fixed plate 22, it seals the pressure relief port 23. The spring 25 is sleeved on the connecting rod at the top of the pressure relief valve 24, and both ends of the spring 25 are fixedly connected to the pressure relief valve 24 and the top of the fixed cylinder 21, respectively. At least one side groove 26 is formed on the side wall of the fixed cylinder 21, and the vertical position of the side groove 26 is higher than that of the pressure relief port 23. In this embodiment, the pressure value of the force that compresses the spring 25 is equal to 90% of the maximum design pressure of the cylinder 1. When the pressure inside the cylinder 1 approaches the compressive strength, the pressure relief valve 24 is forced to move upward, the spring 25 is compressed, and the gas is discharged through the pressure relief port 23-side groove 26 to achieve pressure relief. When the pressure inside the cylinder 1 decreases, the pressure relief valve 24 is reset under the elastic force of the spring 25.

[0057] The above structure enables manual pressurization. The first one-way valve 6 and the second one-way valve 7 ensure precise gas flow, guaranteeing stable pressurization within the cylinder 1. The water outlet control unit allows for manual water spraying as needed. The pressure relief mechanism automatically depressurizes the cylinder 1, ensuring stable and safe operation of the equipment. Example

[0058] When flushing soil aggregates, additives are often added to the water. These additives typically serve one or more purposes, such as improving water quality, cleaning, dissolving, or stabilizing substances. Suitable additives include sodium hexametaphosphate, calcium chloride solution, and sodium dodecyl sulfate. These additives need to be thoroughly mixed and dissolved in the water to be effective. However, different additives have different solubilities, and the lack of stirring during use can easily lead to precipitation or separation. To avoid this, this embodiment is proposed. The difference between this embodiment and Embodiment 1 is that a mixing mechanism is provided at the bottom of the inner cavity of the cylinder 1. This mixing mechanism can mix the fluid inside the cylinder 1 with the additives and other materials through forward and reverse stirring while the piston rod 4 moves up and down.

[0059] refer to Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, the mixing mechanism includes: a connecting rod 27, a connecting cylinder 28, a drive rod 29, a rotating cylinder 30, a drive groove 31, a fixing plate 32, an extension plate 33, a slider 34, a pressure reducing hole 35, a fixing seat 36, and a slide rail 37. In this embodiment, the first one-way valve 6 and the air outlet installed at the bottom of the booster cylinder 3 are both located at an eccentric position. The top end of the connecting rod 27 is fixedly installed on the lower surface of the piston rod 4. The connecting rod 27 slides through the booster cylinder 3, and a rubber gasket is provided at the sliding connection between the two to ensure airtightness. The connecting cylinder 28 is installed at the bottom end of the connecting rod 27. There are two drive rods 29, which are symmetrically installed at the bottom end of the connecting cylinder 28. The fixing seat 36 is fixedly installed at the center of the bottom end of the inner cavity of the cylinder 1. The rotating cylinder 30 is rotatably installed at the center of the top end of the fixing seat 36. The rotating cylinder 30 is a hollow cylinder with an open top. There are two drive grooves 31, which are symmetrically opened on the inner wall of the rotating cylinder 30, and the drive rod 29 is slidably installed in the drive groove 31. The drive groove 31 is inclined from top to bottom along the circumference. There are three fixed plates 32, equidistantly mounted on the side wall of the rotating cylinder 30 along the circumference. The extension plate 33 is a hollow rectangular structure open on one side, and is slidably mounted on the fixed plate 32. The slider 34 is mounted on the bottom end of the extension plate 33 on the side opposite to the rotating cylinder 30. Several pressure-reducing holes 35 are arrayed on the outer wall of the extension plate 33. There are three slide rails 37, equidistantly mounted on the fixed base 36 along the circumference, and the slider 34 is slidably mounted within the slide rails 37. The slide rails 37 are inclined outwards from the center of the fixed base 36.

[0060] The specific working principle of the above structure during use is as follows: When the piston rod 4 moves up and down to pressurize the cylinder 1, the connecting rod 27 and the connecting cylinder 28 move up and down synchronously. When the connecting rod 27 and the connecting cylinder 28 move upward, the rotating cylinder 30 can be rotated by the cooperation of the drive rod 29 and the drive groove 31. When the connecting rod 27 and the connecting cylinder 28 move downward, the rotating cylinder 30 reverses direction. During this process, when the rotating cylinder 30 rotates, the fixed plate 32 and the extension plate 33 move in a circular motion synchronously. At this time, the slider 34 slides in the slide rail 37, so while rotating, the extension plate 33 will move outward radially along the fixed seat 36. When the fixed plate 32 and the extension plate 33 mix with the water flow, the water flow can be allowed to pass through the pressure reducing hole 35, reducing resistance. When the rotating cylinder 30 reverses direction, the extension plate 33 retracts and resets. The above structure enables the fluid to be agitated while being pressurized, thus achieving material mixing. It also ensures that the rotating drum 30 rotates in both directions to improve mixing efficiency, avoids the generation of vortex flow, and allows the extension plate 33 to extend and retract simultaneously, further improving mixing efficiency.

[0061] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
