[0011] In the above or some embodiments, a plurality of rectangular grooves are opened on the outer wall of the barrel, the inner end of the rectangular groove penetrates to the mixing cavity, and the side wall of the barrel at the outer end of the rectangular groove is fixedly attached to an acrylic plate through a screw; the liquid level in the mixing cavity can be observed through the acrylic plate and the rectangular groove.

[0012] A liquid fertilizer irrigation deployment method is provided: S1: connecting the device in the irrigation pipeline, so that the irrigation water flow can flow from the water inlet to the water outlet; S2: before starting irrigation, pour the required liquid fertilizer into each square barrel, and push all the push plates into the sunken groove, and tighten all the studs; S3: after starting irrigation, first open the through groove close to the water outlet through the adjusting module, then slowly and gradually expand the opening size of the through groove close to the water inlet, and stop moving the adjusting module when the liquid height in the mixing cavity is observed to be stable near the barrel axis, and then tighten the two studs; S4: adjust the pumping speed of each quantitative module according to the formula proportion, loosen the stud, slowly pull out the push plate from the sunken groove to a certain scale, and then tighten the stud; S5: observe the remaining amount of liquid fertilizer in the square barrel during irrigation, and add in time until the irrigation is completed; S6: after the irrigation is completed, pour out the remaining liquid fertilizer in the square barrel, and clean the device.

[0013] The technical scheme has the following technical effects: 1. The present application provides a plurality of square barrels arranged along the axis of the barrel on the outer side of the barrel, each square barrel is connected to the mixing cavity through a quantitative module, and the length of the push plate in each quantitative module can be controlled to mix different liquid fertilizers in each square barrel according to the set proportion, and the formula proportion adjustment is convenient and intuitive.

[0014] 2. Every time the filter plate of this solution rotates one circle with the inner cylinder, each quantitative module injects liquid fertilizer into the mixing chamber once. After the liquid fertilizer is diluted once in the mixing chamber, it is diluted twice when it intersects with the water flow at the outlet. This not only complies with the principle of "now-mixed, now-available", effectively improves the absorption rate of liquid fertilizer, but also allows unused excess liquid fertilizer to be poured out to avoid waste. It also complies with the requirements of secondary dilution of liquid fertilizer, making the dilution concentration of liquid fertilizer more uniform, greatly reducing the risk of root burn caused by excessive concentration in some areas.

[0015] 3. The inner cylinder of this solution not only forms a turbine flowmeter together with the turbine, but also drives the device to operate while making the flow rate concrete as the number of rotations of the inner cylinder. Moreover, the spiral filter plate on the outer side of the inner cylinder can not only push the liquid in the mixing chamber to flow backward and stir the water flow and liquid fertilizer in the mixing chamber, but also push the piston to move in the sink hole to realize the pumping of liquid fertilizer. The structure is ingenious and compact.

[0016] 4. This solution has an adjustment module on each side of the mixing chamber. By controlling the opening size of the through slot by the adjustment module, the liquid level in the mixing chamber can be maintained near the axis of the barrel, so that the filter plate continuously disturbs the liquid surface and knocks bubbles into the mixed liquid during rotation. Compared with the existing device in which the stirring rod is completely immersed in the solution, this solution further enhances the stirring effect of the liquid fertilizer in the mixing chamber by virtue of the bursting and rising of bubbles.

[0017] 5. This solution is equipped with multiple partitions in the mixing chamber, which divide the left part of the mixing chamber into multiple units. After entering the mixing chamber, each liquid fertilizer is first mixed with the water flow in the unit, and then flows through the filter plate under gravity to the right part of the mixing chamber and is mixed with other diluted liquid fertilizer mother liquors. This meets the requirements of adding various liquid fertilizers one by one and mixing them gradually during liquid fertilizer preparation, and eliminates the precipitation or flocculation that may be caused by uniform addition.

[0018] 6. The two through grooves of this scheme are respectively located on the left and right parts of the mixing chamber, so that the solution that is not filled in the mixing chamber can only flow to the outlet after flowing counterclockwise, so that the liquid flow direction is opposite to the direction of the filter plate, so that each liquid passes through the filter plate at least once, avoiding the situation of mixing dead corners.

[0024] In use, the device is placed on the ground before irrigation, the inlet 2 and the outlet 3 are communicated with the irrigation pipeline, so that the irrigation water flow can flow from the inlet 2 to the outlet 3, and then the required liquid fertilizer is classified and poured into each square barrel 12, at this time, the liquid fertilizer with high concentration or high viscosity can be poured into the square barrel 12 close to the inlet 2, so as to prolong the dilution time of the liquid fertilizer with high concentration or high viscosity, and then all the push plates 36 are pushed into the sink 30, and all the studs 35 are tightened, so as to avoid that the quantitative module 13 which is not adjusted injects the liquid fertilizer into the barrel 1 at the beginning of irrigation; After irrigation begins, water flows from the water inlet 2, through the inner cylinder 5 and the circular tube 15 to the water outlet 3, and then irrigates the farmland through the irrigation pipe. At this time, the through groove 7 near the water outlet 3 is first opened by the regulating module 8, and then the opening size of the through groove 7 near the water inlet 2 is slowly and gradually expanded. When the opening of the through groove 7 changes from small to large, the flow rate in the mixing chamber 6 also changes from small to large. When the liquid level in the mixing chamber 6 is observed to be stable near the axis of the circular barrel 1 through the rectangular groove 37, the regulating module 8 is stopped from being moved, and the bolts 20 on the two regulating modules 8 are tightened to maintain the liquid level in the mixing chamber 6 near the axis of the circular barrel 1. Since the circular tube 15 can prevent the water flow at the water outlet 3 from flowing back, the liquid in the mixing chamber 6 flows to the through groove 7 near the water outlet 3 as a whole, and intersects with the water flow in the circular tube 15 at the water outlet 3; After the liquid level in the mixing chamber 6 is stabilized, the pumping speed of each quantitative module 13 is adjusted one by one according to the formula ratio. The adjustment method is: loosen the stud 35, slowly pull the push plate 36 out of the sink 30 to a certain scale, and then tighten the stud 35. Since the turbine 9 is fixed on the inside of the inner cylinder 5 and the diameter of the inner cylinder 5 remains unchanged, the inner cylinder 5 and the turbine 9 are equivalent to the turbine 9 flowmeter. The volume of liquid flowing through the inner cylinder 5 after one rotation of the inner cylinder 5 is fixed. The volume of liquid fertilizer pumped out each time by the quantitative module 13 is also a fixed value controlled by the push plate 36. The liquid fertilizer injected into the mixing chamber 6 is mixed with the water flow under the stirring action of the filter plate 10. The diluted mother liquor intersects with the water flow in the circular tube 15 at the water outlet 3, so the concentration of the liquid fertilizer at the water outlet 3 remains unchanged, thereby achieving the purpose of diluting the liquid fertilizer to a specified concentration. During the irrigation process, observe the remaining liquid fertilizer in the square barrel 12 and add it in time to avoid the lack of certain liquid fertilizers until the irrigation is completed. After the irrigation is completed, lift the square barrel 12 out of the shell 11 and pour out the remaining liquid fertilizer in the square barrel 12. Since the length of the hose is greater than the height of the shell 11, the connection between the square barrel 12 and the quantitative module 13 is not destroyed at this time. Finally, put the square barrel 12 back into the shell 11, add clean water into the square barrel 12, and keep the inner cylinder 5 rotating for a period of time to achieve the purpose of cleaning the device and prevent residual liquid fertilizer from corroding the inner wall of the device.

[0025] Reference Figure 5 ,and Figure 9 In the embodiment shown, the barrel 1 is divided into left and right parts along the vertical plane passing through the axis, the through hole 14 is located on the left side wall of the barrel 1, and two oblong holes 16 are opened on the right side wall of the barrel 1. The oblong holes 16 pass through the inner wall of the barrel 1, and the adjustment module 8 includes an arc-shaped rubber block 17. The outer wall of the rubber block 17 is fixed with a connecting block 18 by screws, and the other end of the connecting block 18 is welded with an arc-shaped plate 19, which is coaxial with the rubber block 17. When installed, the rubber block 17 is fitted with the side wall of the disc 4, the connecting block 18 is located in the oblong hole 16, the arc-shaped plate 19 is fitted with the outer wall of the barrel 1, and a threaded hole is opened on the arc-shaped plate 19, and a bolt 20 is provided in the threaded hole.

[0026] The outer wall of the rubber block 17 seals the long circular hole 16 under the tension of its own shape, the rubber block 17 near the water inlet 2 seals the through slot 7 under the water pressure and water flow impact at the water inlet end, the rubber block 17 near the water outlet 3 has lower sealing requirements, even if there is a gap under the water flow impact, it does not matter, as long as it can hinder the water flow, it can control the liquid level in the mixing chamber 6, when adjusting the adjusting module 8, the rubber block 17 can be rotated by pushing the arc-shaped plate 19, the opening size of the through slot 7 is adjusted, and then the liquid height in the mixing chamber 6 is controlled to be maintained near the axis of the barrel 1, after the liquid fertilizer is injected into the mixing chamber 6 by the quantitative module 13, the liquid fertilizer is mixed with the water flow in the mixing chamber 6, since the liquid level in the mixing chamber 6 is only near the axis of the barrel 1, when the filter plate 10 rotates, the air above the inner cylinder 5 is hit into the liquid in the mixing chamber 6, and the chaotic liquid level and the bubbles hit into the liquid are beneficial to the mixing of the water flow and the liquid fertilizer in the mixing chamber 6 when they break and rise. Compared with the existing stirring rod fully immersed in the liquid for stirring, the filter plate 10 of the scheme not only can disturb the liquid level, but also can further disturb the liquid flow through the bubbles hit into the liquid, and the mixing and dilution effect of the filter plate 10 is strengthened.

[0027] Referring to Figure 5 and Figure 6 An embodiment is shown, the filter plate 10 has the same rotation direction as the blades on the turbine 9, when the fluid drives the inner cylinder 5 to rotate through the turbine 9, the inner cylinder 5 pushes the liquid in the left mixing chamber 6 upward through the filter plate 10, the through slot 7 on the disc 4 near the water inlet 2 is located in the left cavity of the barrel 1, and the through slot 7 on the disc 4 near the water outlet 3 is located in the right cavity of the barrel 1.

[0028] In use, although the filter plate 10 has the same rotation direction as the blades on the turbine 9, the liquid in the mixing chamber 6 flows backward under the push of the filter plate 10, but since the liquid in the mixing chamber 6 does not cover the top of the inner cylinder 5, and the through slot 7 near the water outlet 3 is located in the right cavity of the barrel 1, the liquid in the mixing chamber 6 also flows downward through the filter plate 10 under the action of gravity, that is, the liquid in the mixing chamber 6 flows counterclockwise, which is opposite to the rotation direction of the filter plate 10, so that each part of the liquid must pass through the filter plate 10 before flowing to the water outlet 3, achieving the effect of forced stirring.

[0029] Referring to Figure 5 An embodiment is shown, a plurality of partitions 21 are fixed on the inner wall of the barrel 1, the partitions 21 are in the form of a fan ring, the partitions 21 are located on the left of the mixing chamber 6, and the inner wall of the partitions 21 is attached to the outer wall of the inner cylinder 5, the partitions 21 divide the left part of the mixing chamber 6 into a plurality of units, each unit is in communication with a through hole 14, and a plurality of accommodation grooves 22 are formed in the filter plate 10.

[0030] In use, the quantitative module 13 injects different liquid fertilizers into different units, and each unit is not communicated with each other at the left part of the mixing cavity 6, so each kind of liquid fertilizer can only pass through the filter plate 10 once in the unit to reach the right part of the mixing cavity 6, and then be mixed with the liquid fertilizer behind to flow to the water outlet 3 or be pushed into the unit behind by the filter plate 10 for further mixing, so as to achieve the effect that different kinds of liquid are mixed one by one, meet the requirement of adding and diluting one by one when configuring liquid fertilizer, avoid the precipitation and flocculation phenomenon that may be caused by synchronous addition, and be beneficial to the stability of various liquid fertilizer elements.

[0031] With reference to Figure 7 and Figure 8 An embodiment is shown, the quantitative module 13 includes an arc block 23, the arc block 23 is attached to the outer wall of the barrel 1, one end of the arc block 23 is provided with an arc-shaped counterbore 24, the counterbore 24 is threadedly connected with a plunger 25 at the hole opening, the counterbore 24 is provided with a piston 26, and the length of the piston 26 is greater than the length of the sliding track, a spring 27 is arranged between the plunger 25 and the piston 26, two connecting holes 28 are provided at the bottom of the counterbore 24, and the two connecting holes 28 are respectively communicated with the square barrel 12 and the through hole 14, and a one-way valve is arranged in each connecting hole 28; A pad 29 is arranged between the arc block 23 and the barrel 1, the pad 29 is fixedly connected to the side wall of the barrel 1 by screws, a recess 30 is provided on the attached surface of the pad 29 and the barrel 1, the recess 30 penetrates to the side wall of the pad 29 on the side close to the hole opening of the counterbore 24, a first sliding groove 31 penetrating the counterbore 24 is provided at the bottom of the recess 30, a second sliding groove 32 is provided on the part of the side wall of the barrel 1 coinciding with the recess 30, a long rod 33 is arranged in the first sliding groove 31, one end of the long rod 33 is fixedly connected to the piston 26, the other end of the long rod 33 is hingedly connected with a short rod 34, the short rod 34 extends into the mixing cavity 6, a torsional spring is arranged on the hinged shaft of the long rod 33 and the short rod 34, the torsional spring always keeps the long rod 33 and the short rod 34 coaxial, a threaded hole penetrating the recess 30 is provided on the outer wall of the pad 29, a stud 35 is arranged in the threaded hole, a push plate 36 is arranged in the recess 30, the push plate 36 is provided with a scale, and the push plate 36 only contacts with the long rod 33 when the piston 26 moves.

[0032] In use, the filter plate 10 drives the short rod 34 to compress the torsional spring to swing when the filter plate 10 rotates one round with the inner cylinder 5, and then the piston 26 can return under the action of the compressed spring, so that the two one-way valves can inject liquid fertilizer into the mixing cavity 6, and the filter plate 10 can continue to rotate with the inner cylinder 5, and because the length of the piston 26 is greater than the length of the sliding track, even if the piston 26 is compressed to the maximum stroke position, the side wall of the piston 26 can still seal the first sliding groove 31 to ensure that the piston 26 is sealed in the pump cavity; In this process, since the filter plate 10 is spiral, the dosing module 13 arranged along the axis of the barrel 1 will not be in contact with the filter plate 10 at the same time, and the multiple short rods 34 are pushed by the filter plate 10 one by one, dispersing the load required to drive the multiple dosing modules 13, reducing the resistance when the inner cylinder 5 rotates, so that the device can operate only by water flow; When the push plate 36 is pulled out of the sink 30, the scale on the push plate 36 changes from small to large, and when the scale of a certain value is aligned with the slot of the sink 30, it means that the volume of the space swept by the piston 26 when the long rod 33 is in contact with the push plate 36 is the value, realizing quantitative pumping of liquid fertilizer, and cooperating with the turbine 9 flow meter composed of the inner cylinder 5 and the turbine 9, realizing dilution of various liquid fertilizers to the specified concentration according to the formula.

[0035] In addition, when the device is installed, the barrel 1 is composed of two left and right half barrels 1, which is convenient for welding the partition plate 21 and the disc 4 in the barrel 1, and can also facilitate the installation of the inner cylinder 5. At the same time, during assembly, sealing pads are provided between the two half barrels 1 and between the barrel 1 and the acrylic plate 38 to prevent leakage of liquid in the barrel 1 and the mixing chamber 6, and sealing pads are provided between the dosing module 13 and the through hole 14 to prevent leakage of liquid fertilizer from the dosing module 13 to the mixing chamber 6; and the above-mentioned installation method is only one way, and in actual production, the blank production assembly is carried out according to the actual requirements of the process card.
