Description

Technical Field

[0001] The invention relates to the technical field of water-fertilizer integration, and in particular to a water-fertilizer ratio control device for water-fertilizer integration. Background Art

[0002] In integrated fertigation, water-fertilizer ratio regulation precisely controls the fertilizer-water ratio based on soil nutrient status, crop needs, and growth stage. In an integrated fertigation system, the appropriate fertilizer must be selected based on soil nutrient status and crop type. The fertilizer is dissolved in water to form a fertilizer solution, which is then delivered to the crop roots through irrigation systems such as drip irrigation and sprinkler irrigation.

[0003] For example, announcement number CN220712075U proposes an integrated water-fertilizer ratio control device, comprising an operating table and a mixing tank, wherein the operating table is provided with a spiral feeding device and a water storage tank, the mixing tank is located below the operating table, the bottom end of the operating table is provided with an adjusting plate and an electric telescopic rod, the top of the mixing tank is provided with a top cover, a mixing box is provided between the output end of the electric telescopic rod and the top cover, the mixing box is provided with a stirring mechanism, a fixing mechanism is provided between the adjusting plate and the top cover, the fixing mechanism comprises a fixing block, a fixing hole and a slide groove, the top cover is moved upward by the electric telescopic rod, and then the top cover is fixed by the fixing mechanism, the personnel can flush the inside of the mixing tank through the top of the mixing tank, and the personnel can directly observe the inside of the mixing tank, which is convenient for observing the cleaning status and the cleaning is more thorough.

[0004] At present, in the process of water and fertilizer mixing, solid fertilizer is generally placed in a mixing tank, water is added and then stirred by a stirring device until the fertilizer is completely dissolved to obtain water and fertilizer. However, if the mixing amount is large, it will take a long time for the solid fertilizer to be completely dissolved, and the efficiency is low. In addition, after the water and fertilizer in the mixing tank are mixed, they will be sprayed to the outside. The mixing tank sprays water and fertilizer to the outside through a feed pipe. If the connection between the feed pipe and the discharge pipe is blocked, it is inconvenient to replace it during use, which will affect the subsequent injection pressure of the water and fertilizer, and thus affect the spraying effect of the water and fertilizer. Moreover, even if an anti-blocking component is set to avoid blockage at the connection between the feed pipe and the discharge pipe, which makes it impossible to use the fertilizer normally, the replaced circular hole on the switching disk needs to be cleared in time to avoid subsequent inability to use it.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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.

[0034] In order to solve the technical problem that in the process of water and fertilizer mixing, solid fertilizer is generally put into the mixing tank 1, and then water is added and stirred by a stirring device until the fertilizer is completely dissolved to obtain water fertilizer, but if the mixing amount is large, it takes a long time for the solid fertilizer to be completely dissolved, which is inefficient. Figure 1 - Figure 6 As shown, the following preferred technical solutions are provided:

[0035] A water-fertilizer ratio control device for an integrated water-fertilizer system includes a mixing tank 1. The top of the mixing tank 1 is fixedly connected to a feed pipe 11, the bottom of the mixing tank 1 is fixedly connected to a delivery pipe 12, and a control valve 13 is installed inside the delivery pipe 12. In the process of mixing water and fertilizer, solid fertilizer is usually placed in the mixing tank 1, water is added, and the mixture is stirred by a stirring device until the fertilizer is completely dissolved to obtain water-fertilizer. An auxiliary component 2 is installed on the side wall of the mixing tank 1. By providing the auxiliary component 2, compared with providing other driving mechanisms, the device uses a water pump 23 to pump water and supply water, thereby driving two crushing rollers 213 to rotate and crush the solid fertilizer, saving energy consumption and improving the use effect of the device. The solid fertilizer is not crushed, so that it can be quickly dissolved in water, thereby improving the mixing efficiency, accelerating the mixing rate, and improving the use effect of the device.

[0036] An anti-blocking component 3 is installed at one end of the delivery pipe 12. By setting the anti-blocking component 3, the water and fertilizer inside the deployment tank 1 are pressurized and discharged along the delivery pipe 12. If the circular hole 36 between the delivery pipe 12 and the discharge pipe 37 is blocked, the water pressure between the circular hole 36 and the delivery pipe 12 will increase, thereby forcing the switching disk 35 to move downward. During the downward movement of the switching disk 35, the telescopic rod 33 and the first spring 34 are both in a compressed state, and the annular bevel 38 is utilized, wherein the initial position of the slider 39 is located at the highest point of the annular bevel 38. When the water pressure inside the circular hole 36 increases, the switching disk 35 will rotate along the annular bevel 38 during the downward movement. When the switching disk 35 slides to the lowest position of the annular bevel 38, Under the elastic action of a spring 34, the switching disk 35 is pushed upward, thereby switching the position of the blocked circular hole 36 and the unblocked circular hole 36 of the switching disk 35. During the position switching process of the circular hole 36 of the switching disk 35, it will move against the feed pipe 12 and the discharge pipe 37. Since the feed pipe 12 and the discharge pipe 37 are both made of rubber, there will be no limiting effect during the movement of the switching disk 35. After the position switching of the circular hole 36 is completed, the feed pipe 12 and the discharge pipe 37 will re-enter the switched circular hole 36 under the plastic action of the rubber. By timely replacing the blocked circular hole 36, blockage during the water and fertilizer spraying process can be avoided, ensuring that the device can work normally and improving the practicality of the device.

[0037] A dredging component 4 is installed on the top of the anti-blocking component 3. By setting the dredging component 4 and utilizing the anti-blocking component 3 to rotate the switching disk 35, the blocked circular hole 36 is moved, so that the unblocked circular hole 36 is connected to the feed pipe 12 and the discharge pipe 37, thereby continuing the supply of water and fertilizer. At this time, the blocked circular hole 36 will move to the bottom of the push rod 46, and then the electromagnet 44 will be energized, so that the electromagnet 44 and the permanent magnet 45 will generate like magnetic poles. Under the action of magnetic repulsion, the connecting plate 43 and the push rod 46 are pushed downward. At this time, the second spring 42 is in a stretched state. During the downward movement of the push rod 46, it will enter the blocked circular hole 36 and dredge the blockage in the circular hole 36, so that the blockage in the circular hole 36 falls along the through hole 47, and the blocked circular hole 36 is dredged in time for subsequent continued use.

[0038] The auxiliary component 2 includes a first hopper 21 and a second hopper 22. The first hopper 21 and the second hopper 22 are both fixedly connected to the inner wall of the mixing tank 1. A water storage tank 27 is fixedly connected to the side wall of one side of the mixing tank 1, and a water pump 23 is fixedly connected to the side wall of the other side of the mixing tank 1. The input end of the water pump 23 is fixedly connected to a water pumping pipe 24.

[0039] One end of the water pumping pipe 24 passes through the side walls of the mixing tank 1 and the top wall of the water storage tank 27 in sequence and then extends to the inside of the water storage tank 27. The water pumping pipe 24 is located on a section of the bottom wall inside the mixing tank 1 and is fixedly connected to multiple water supply pipes 25 at equal intervals. A one-way valve 26 is installed inside each water supply pipe 25. The output end of the water pump 23 is fixedly connected to a connecting pipe 28. The side wall of the mixing tank 1 is fixedly connected to a first installation box 29, and one end of the connecting pipe 28 is fixedly connected to the top wall of the first installation box 29.

[0040] The inner wall of the first installation box 29 is symmetrically connected to a rotating rod 210, and one end of each rotating rod 210 passes through the side wall of the first installation box 29 and the side wall of the mixing tank 1 in sequence and then rotates to be connected to the inner wall of the mixing tank 1. The two rotating rods 210 are located between the first hopper 21 and the second hopper 22.

[0041] Each rotating rod 210 is fixedly connected to a crushing roller 213 on a side wall located inside the mixing tank 1, and the rotating rod 210 is fixedly connected to a vortex blade 211 on a side wall located in a section of the first installation box 29. The bottom wall of the first installation box 29 is symmetrically fixedly connected to an inclined block 212. The bottom wall of the first installation box 29 is fixedly connected to a drainage pipe 214, and one end of the drainage pipe 214 is fixedly connected to the top wall of the water tank 27.

[0042] In this solution, by setting up the auxiliary component 2, in order to avoid the solid fertilizer taking too long to dissolve in water and affecting the mixing efficiency, before the solid fertilizer is added through the feed pipe 11, the water pump 23 is started. At this time, the one-way valve 26 is in a closed state, so that the water inside the water storage tank 27 will be pumped out through the pumping pipe 24 and then transported to the first installation box 29 through the connecting pipe 28. The water flow input into the first installation box 29 is a high-pressure water flow. The high-pressure water flow will pass between the two vortex blades 211. The impact force generated by the high-pressure water flow will drive the two vortex blades 211 to rotate, thereby making the rotating rod 210 The water flows through the two vortex blades 211 and enters the drain pipe 214 under the guidance of the inclined block 212, and finally enters the water storage tank 27 again, forming a water circulation, which continuously impacts the vortex blades 211, causing the two vortex blades 211 to rotate, thereby driving the two pulverizing rollers 213 to rotate. Then, under the action of the first hopper 21, the solid fertilizer is concentrated and guided so that the solid fertilizer falls between the two rotating pulverizing rollers 213, where it is pulverized and quickly dissolved in water, thereby improving the mixing efficiency.

[0043] When the solid fertilizer is added and water supply is needed, it is only necessary to open the one-way valve 26. The water in the water tank 27 will be discharged through multiple water supply pipes 25 during the process of being drawn out along the pumping pipe 24 under the action of the water pump 23, and enter the bottom of the mixing tank 1 through the first hopper 21 and the second hopper 22 to mix with the crushed solid fertilizer, so that the solid fertilizer is dissolved in water for subsequent water and fertilizer spraying; compared with setting up other driving mechanisms, this device uses the water pump 23 to pump water and supply water, thereby driving the two crushing rollers 213 to rotate and crush the solid fertilizer, saving energy consumption and improving the use effect of the device.

[0044] In order to solve the problem that after the water and fertilizer in the mixing tank 1 are mixed, they will be sprayed to the outside, and the mixing tank 1 sprays the water and fertilizer to the outside through the feeding pipe 12. If the connection between the feeding pipe 12 and the discharge pipe 37 is blocked, it is not convenient to replace it during use, which will affect the subsequent spraying pressure of the water and fertilizer, thereby affecting the spraying effect of the water and fertilizer. Figure 7 - Figure 10 As shown, the following preferred technical solutions are provided:

[0045] The anti-blocking component 3 includes a connecting rod 310, one end of the connecting rod 310 is fixedly connected to the bottom wall of the mixing tank 1, and the other end of the connecting rod 310 is fixedly connected to the second installation box 31. The bottom wall of the second installation box 31 is rotatably connected to a turntable 32, and the top of the turntable 32 is symmetrically fixedly connected to a telescopic rod 33, and the movable ends of multiple telescopic rods 33 are commonly fixedly connected to a switching disk 35.

[0046] The top of the turntable 32 is symmetrically fixedly connected to the first spring 34, and one end of each first spring 34 is fixedly connected to the bottom end of the switching disk 35. The first spring 34 is sleeved on the outer wall of the telescopic rod 33, and a plurality of circular holes 36 are opened at equal angles on the inner wall of the switching disk 35. The inner bottom wall of the second installation box 31 is fixedly connected to the discharge pipe 37, and one end of the discharge pipe 37 and the feed pipe 12 are located inside the same circular hole 36.

[0047] One end of the feed pipe 12 and the discharge pipe 37 are both made of rubber. Sliders 39 are fixedly connected to the side wall of the switching disk 35 at equal angles. An annular inclined groove 38 is opened on the inner wall of the second installation box 31, and each slider 39 is located inside the annular inclined groove 38.

[0048] In this solution, the water and fertilizer inside the mixing tank 1 are pressurized to be discharged along the delivery pipe 12. If the circular hole 36 between the delivery pipe 12 and the discharge pipe 37 is blocked, the water pressure between the circular hole 36 and the delivery pipe 12 will increase, thereby forcing the switching disk 35 to move downward. During the downward movement of the switching disk 35, the telescopic rod 33 and the first spring 34 are both in a compressed state, and the annular bevel 38 is utilized, wherein the initial position of the slider 39 is located at the highest point of the annular bevel 38. When the water pressure inside the circular hole 36 increases, the switching disk 35 will rotate along the annular bevel 38 during its downward movement. When the switching disk 35 slides to the lowest position of the annular bevel 38, the elastic action of the first spring 34 Under the action of the pressure reducing device 32, the switching disk 35 is pushed upward, thereby switching the position of the blocked circular hole 36 and the unblocked circular hole 36 of the switching disk 35. During the position switching process of the circular hole 36 of the switching disk 35, it will move against the feed pipe 12 and the discharge pipe 37. Since the feed pipe 12 and the discharge pipe 37 are made of rubber, there will be no limiting effect during the movement of the switching disk 35. After the position switching of the circular hole 36 is completed, the feed pipe 12 and the discharge pipe 37 will re-enter the switched circular hole 36 under the plastic action of the rubber. By replacing the blocked circular hole 36 in time, blockage during the water and fertilizer spraying process can be avoided, ensuring that the device can work normally and improving the practicality of the device.

[0049] In order to solve the technical problem that even if the anti-blocking component 3 is set to avoid the connection between the feeding pipe 12 and the discharge pipe 37 from being blocked and unable to be used normally, the replaced circular hole 36 on the switching disk 35 needs to be cleared in time to avoid the subsequent inability to continue to use, such as Figure 1 - Figure 3 and Figure 11 - Figure 12 As shown, the following preferred technical solutions are provided:

[0050] The dredging component 4 includes a bracket 41, which is fixedly connected to the top of the second installation box 31. The bottom wall of the bracket 41 is symmetrically fixedly connected to the second spring 42. The two second springs 42 are commonly fixedly connected to the connecting plate 43. The top of the connecting plate 43 is fixedly connected to a permanent magnet 45.

[0051] The bottom end of the bracket 41 is fixedly connected to the electromagnet 44, the bottom end of the connecting plate 43 is fixedly connected to the top rod 46, and the bottom wall of the second installation box 31 is provided with a through hole 47. The top rod 46 is slidably connected to the top of the second installation box 31, the circular hole 36 and the through hole 47.

[0052] In this solution, the anti-blocking component 3 is used to rotate the switching disk 35, and after the blocked circular hole 36 is moved, the unblocked circular hole 36 is connected to the feeding pipe 12 and the discharge pipe 37, so as to continue the water and fertilizer supply. At this time, the blocked circular hole 36 will move to the bottom of the push rod 46, and then the electromagnet 44 is energized, so that the electromagnet 44 and the permanent magnet 45 generate the same magnetic poles. Under the action of magnetic repulsion, the connecting plate 43 and the push rod 46 are pushed downward. At this time, the second spring 42 is in a stretched state. During the downward movement of the push rod 46, it will enter the blocked circular hole 36 and clear the blockage in the circular hole 36, so that the blockage in the circular hole 36 falls along the through hole 47, thereby clearing the blocked circular hole 36 in time for subsequent use; after the blocked circular hole 36 is cleared, the electromagnet 44 is powered off, and under the elastic force of the second spring 42, the connecting plate 43 and the push rod 46 are pulled to retract and move upward to reset, so as to clear the subsequent blocked circular hole 36 in time, thereby improving the practicality of the device.
