[0002] Aggregates are the basic units of soil structure and the material basis for a healthy soil structure. Their distribution is a key indicator of soil fertility. Typically, treated soil or aggregate distribution obtained by dry sieving is mixed in appropriate proportions and then sieved in water using a sieve (wet sieving) to determine the number and distribution of water-stable aggregates.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0025] Example 1:

[0026] 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 member 10, a water outlet pipe, and a water outlet control unit. The fixed cylinder 2 is mounted at the top center of the cylinder 1. The fixed cylinder 2 is a hollow cylindrical structure with a threaded outer wall. The cylinder 1 is provided with a matching internal thread. The fixed cylinder 2 is fixedly connected to the cylinder 1 by screwing, and a rubber gasket is provided between the two to enhance sealing. The pressurizing unit is mounted within the fixed cylinder 2, and the bottom of the pressurizing unit extends into the inner cavity of the cylinder 1. The cylinder 1 is filled with a flushing fluid. In this embodiment, clean water is used as the flushing fluid. The clean water liquid level leaves a space from the top of the inner cavity of the cylinder 1, and the bottom of the pressurizing unit does not contact the liquid surface. The pressurizing unit is used to increase the air pressure in the space above the liquid surface. The mounting member 10 is mounted at an eccentric position at the top of the cylinder 1. The mounting member 10 is a hollow cylinder, and the bottom of the mounting member 10 extends into the cylinder 1. The water outlet pipe is installed in the mounting member 10, the top of the water outlet pipe extends out of the top of the mounting member 10, and the bottom of the water outlet pipe extends into the bottom of the inner cavity of the cylinder 1. The water outlet control unit is installed at the top of the cylinder 1, and the water outlet control unit is used to control the opening and closing of the water outlet pipe.

[0027] refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The boosting part includes: a boosting 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 hole 9. The boosting cylinder 3 is fixedly installed in the mounting part 10, and an air outlet is installed at the bottom end of the boosting cylinder 3. The piston rod 4 is installed in the boosting cylinder 3 so as to slide up and down. The bottom of the piston rod 4 is a rubber piston. The piston fits tightly with the inner cavity of the boosting cylinder 3 and has good airtightness. When it moves, it can push the air in the inner cavity of the boosting cylinder 3. The handle 5 is installed on the top of the piston rod 4. The first one-way valve 6 is installed on the air outlet at the bottom end of the boosting cylinder 3 to control the flow direction of the gas in the boosting cylinder 3. In this embodiment, the first one-way valve 6 ensures that the air in the boosting cylinder 3 can flow into the cylinder body 1 and prevents reverse flow. The second one-way valve 7 is installed at the bottom end of the boosting cylinder 3. One side of the second one-way valve 7 is connected to the inner cavity of the boosting cylinder 3. In this embodiment, the second one-way valve 7 ensures that the air flows into the boosting cylinder 3 and prevents reverse flow. One end of the air pipe 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 boost cylinder 3, and the other end of the air pipe 8 is connected to these holes. It is worth noting that a retaining groove 201 is provided on the outer wall of the fixed cylinder 2. This retaining groove 201 is used to accommodate the air pipe 8, preventing it 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.

[0028] The above structure operates as follows: Water is poured into cylinder 1 to keep the liquid level below a predetermined level. Then, the fixed cylinder 2 is screwed in and fixed together with the booster unit. Pulling handle 5 upward causes piston rod 4 to move upward along the axial direction of booster cylinder 3. Air enters booster cylinder 3 through air hole 9, air pipe 8, and second one-way valve 7. Subsequently, pressing handle 5 downward causes air in booster cylinder 3 to flow through first one-way valve 6 into cylinder 1, increasing the pressure above the liquid level within cylinder 1.

[0029] The water outlet pipeline includes an upper water pipe 11 and a lower water pipe 12. The upper water pipe 11 is installed at the top of the cylinder 1 and is connected to the mounting member 10. The lower water pipe 12 is installed at the bottom of the mounting member 10, and the bottom end of the lower water pipe 12 extends to the bottom end of the inner cavity of the cylinder 1.

[0030] refer to Figure 2 、 Figure 3 、 Figure 5 As shown, the water outlet control part 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 arranged on the mounting member 10, and the inner cavities of the two are connected. The baffle 14 is rotatably mounted in the control chamber 13. The inner cavities of the baffle 14 and the control chamber 13 are both circular and coaxial. The through hole 15 is opened at an eccentric position of the baffle 14, and the through hole 15 is arranged corresponding to the inner cavity of the mounting member 10. The extension rod 16 is mounted at the center position of the bottom end of the baffle 14, and the extension rod 16 extends out of the center position of the bottom end of the control chamber 13. The rack 17 is connected to the extension rod 16 through 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 gear 19 is meshed with rack 17, and both can rotate synchronously. Torsion spring 20 is sleeved on rotating rod 18, and the two ends of torsion spring 20 are fixedly connected with rotating rod 18 and the outer wall of cylinder 1 respectively.

[0031] The above structure actually works as follows: the pressure in the chamber of the cylinder 1 is increased by the booster, and then the upper water pipe 11 is aligned with the position to be flushed. The rotating rod 18 is rotated, causing the gear 19 to rotate and drive the rack 17 in a circular motion, which in turn rotates the extension rod 16 and the baffle 14. When the through hole 15 is aligned with the mounting member 10, clean water is sprayed out by the high pressure through the lower water pipe 12, the mounting member 10, and the upper water 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 causes the rotating rod 18 to reverse and return to its original position, and the baffle 14 finally closes the clean water passage.

[0032] When in use, the equipment moves to the bottom of the screen, and a mist or jet nozzle is installed on the top of the upper water pipe 11 as needed. When in use, the screen can be sprayed from top to bottom, and high-pressure water flow can be used to screen soil aggregates, saving water and eliminating the need for manual screening by staff, saving physical effort. The outlet of the upper water pipe 11 is aligned with the aggregate sieve body to flush the soil particles, and the various parts of the sieve body are evenly flushed, from left to right, and then the sieve body is rotated clockwise to flush the inner wall of the sieve body to ensure that no soil particles remain. In actual use, the water pressure will gradually decrease with use, and manual pressure should be applied in time. Flush 5 sieve bodies with manual pressure at least 10-15 times.

[0033] Experimental result 1 of this embodiment: The time required for flushing 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, and each irrigation is 4 L. The average irrigation time is 15 seconds. The time required for four flushes and two irrigations is 45 × 4 + 15 × 2 = 210 seconds. The average amount of water required is 250 ml. The average volume of water-soil mixture received during flushing is 430 ml.

[0034] Experimental result 2 of this example: 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 is 25 seconds. The time required for four flushes and one irrigation is 20 × 4 + 25 = 105 seconds. The average amount of water required is 180 ml. The average volume of water-soil mixture received during flushing is 380 ml.

[0035] refer to Figure 1 and Figure 6The flushing 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 is connected to the inner cavity of the cylinder 1. The fixed plate 22 is installed in the inner cavity of the fixed cylinder 21, and the pressure relief port 23 is opened at the center position of the fixed plate 22. The pressure relief valve 24 is installed in the inner cavity of the fixed cylinder 21 so as to move up and down. The bottom of the pressure relief valve 24 is a rubber plug. The shape of the plug and the shape of the fixed plate 22 are both inverted truncated cones. The two are normally fitted together and have matching sizes. When the plug and the fixed plate 22 fit together, they can seal the pressure relief port 23. The spring 25 is sleeved on the connecting rod at the top of the pressure relief valve 24, and the two ends of the spring 25 are respectively fixedly connected to the pressure relief valve 24 and the top of the fixed cylinder 21. At least one side groove 26 is provided on the sidewall of the fixed cylinder 21, and the side groove 26 is vertically positioned higher than the pressure relief port 23. In this embodiment, the force driving the compression of the spring 25 is equal to 90% of the maximum design pressure of the cylinder 1. When the pressure within the cylinder 1 approaches the compressive strength, the pressure relief valve 24 is forced upward, the spring 25 is compressed, and the gas is discharged through the pressure relief port 23 and the side groove 26, achieving pressure relief. When the pressure within the cylinder 1 decreases, the pressure relief valve 24 returns to its original position under the elastic force of the spring 25.

[0036] The above structure can meet the need for manual pressurization. The provision of the first and second one-way valves 6 and 7 ensures accurate gas flow and stable pressurization of the inner cavity of the cylinder 1. The water outlet control unit can be used to manually spray water for flushing according to actual needs. The pressure relief mechanism can automatically relieve the pressure of the cylinder 1, ensuring the stability and safety of the equipment operation.

[0037] Example 2:

[0038] When soil aggregates are rinsed, auxiliary materials are often added to the clean water. The functions are usually to improve water quality, clean, dissolve, stabilize substances, etc. or to concentrate them. Optional additives include sodium hexametaphosphate, calcium chloride solution, sodium lauryl sulfate, etc. These additives need to be fully mixed and dissolved with clean water to play a role. However, different additives have different solubilities and lack the stirring ability during use, which easily leads to precipitation or separation of the additives during use. In order to avoid this situation, the present embodiment is proposed. The difference between this embodiment and Example 1 is that the bottom end of the inner cavity of the cylinder 1 is provided with a mixing mechanism, which can achieve mixing of the inner cavity fluid of the cylinder 1 with materials such as additives by forward and reverse stirring while the piston rod 4 moves up and down.

[0039] 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 driving rod 29, a rotating cylinder 30, a driving groove 31, a fixing plate 32, an extension plate 33, a slider 34, a pressure relief hole 35, a fixing seat 36, and a slideway 37. In this embodiment, the first one-way valve 6 and the air outlet mounted at the bottom end of the boosting cylinder 3 are both located in eccentric positions. The top end of the connecting rod 27 is fixedly mounted to the lower surface of the piston rod 4. The connecting rod 27 slides through the boosting cylinder 3, and a rubber gasket is provided at the sliding connection between the two to ensure airtightness. The connecting cylinder 28 is mounted at the bottom end of the connecting rod 27. There are two driving rods 29, symmetrically mounted at the bottom end of the connecting cylinder 28. The fixing seat 36 is fixedly mounted at the center of the bottom end of the inner cavity of the cylinder body 1. The rotating cylinder 30 is rotatably mounted 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 driving grooves 31, symmetrically arranged on the inner wall of the rotating cylinder 30, and the driving rod 29 slides within the driving grooves 31. The driving groove 31 is arranged obliquely from top to bottom along the circumferential direction. There are three fixed plates 32, which are equidistantly installed on the side walls of the rotating cylinder 30 along the circumferential direction. The extension plate 33 is a hollow rectangular structure with one side open, and the extension plate 33 is slidably installed on the fixed plate 32. The slider 34 is installed on the bottom end of the extension plate 33 on the side opposite to the rotating cylinder 30. There are several pressure reducing holes 35, which are arranged in an array on the outer wall of the extension plate 33. There are three slideways 37, which are equidistantly installed on the fixed seat 36 along the circumferential direction, and the slider 34 is slidably installed in the slideway 37. The slideway 37 is inclined outward from the center direction of the fixed seat 36.

[0040] The specific working principle of the above structure when in 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 driving rod 29 and the driving groove 31 cooperate to make the rotating cylinder 30 rotate. When the connecting rod 27 and the connecting cylinder 28 move downward, the rotating cylinder 30 reverses. During this process, when the rotating cylinder 30 rotates, the fixed plate 32 and the extension plate 33 move in a synchronous circular motion. At this time, the slider 34 slides in the slide 37, so the extension plate 33 moves radially outward along the fixed seat 36 while rotating, and when the fixed plate 32 and the extension plate 33 mix the water flow together, the water flow can be allowed to pass through the pressure reducing hole 35 to reduce resistance. When the rotating cylinder 30 reverses, the extension plate 33 retracts and resets. The above structure can be used to stir the fluid while increasing the pressure, achieve material mixing, and at the same time ensure that the rotating drum 30 rotates forward and reversely to improve the mixing efficiency, avoid the generation of vortex flow, and can realize the extension and contraction of the extension plate 33 while rotating forward and reversely, further improving the mixing efficiency.

[0041] The above specific embodiments do not limit the scope of protection of the present invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may be made based on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be included within the scope of protection of the present invention.
