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] The water-fertilizer ratio regulation in the water-fertilizer integration technology is to accurately control the ratio of fertilizer and water according to the soil nutrient status, crop needs and growth stage; in the water-fertilizer integration system, it is necessary to first select the appropriate fertilizer according to the soil nutrient status and crop type. The fertilizer is dissolved in water to form a fertilizer solution, which is then transported to the roots of the crop through irrigation equipment 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 a spiral feeding device and a water storage tank are arranged on the operating table, the mixing tank is located below the operating table, an adjusting plate and an electric telescopic rod are arranged at the bottom of the operating table, a top cover is arranged at the top of the mixing tank, a mixing box is arranged between the output end of the electric telescopic rod and the top cover, a mixing mechanism is arranged on the mixing box, a fixing mechanism is arranged 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, a person can flush the inside of the mixing tank through the top of the mixing tank, and the person can directly observe the inside of the mixing tank, which is convenient for observing the cleaning status and making the cleaning more thorough.

[0004] At present, in the process of water-fertilizer mixing, solid fertilizer is generally put into a mixing tank, and then water is added and stirred by a stirring device until the fertilizer is completely dissolved to obtain water-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 the 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 not convenient to replace it during use, which will affect the subsequent injection pressure of the water and fertilizer, and further 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 it normally, the replaced circular hole on the switching disk needs to be cleared in time to avoid subsequent inability to use it.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0021] In order to solve the technical problem that in the process of water-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, and the efficiency is low, such as Figure 1 - Figure 6 As shown, the following preferred technical solutions are provided: A water-fertilizer ratio control device for integrated water-fertilizer comprises a mixing tank 1, wherein the top of the mixing tank 1 is fixedly connected with a feed pipe 11, the bottom of the mixing tank 1 is fixedly connected with 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 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. An auxiliary component 2 is installed on the side wall of the mixing tank 1. By setting the auxiliary component 2, compared with setting other driving mechanisms, the device drives two crushing rollers 213 to rotate during the process of pumping water and supplying water by a water pump 23, thereby crushing the solid fertilizer, saving energy consumption, improving the use effect of the device, and not crushing the solid fertilizer 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.

[0022] An anti-blocking component 3 is installed at one end of the feeding pipe 12. By setting the anti-blocking component 3, the prepared water and fertilizer are pressurized so that the water and fertilizer in the mixing tank 1 are discharged along the feeding pipe 12. If the circular hole 36 between the feeding pipe 12 and the discharge pipe 37 is blocked, the water pressure between the circular hole 36 and the feeding pipe 12 will increase, thereby causing the switching plate 35 to move downward. During the downward movement of the switching plate 35, the telescopic rod 33 and the first spring 34 are both in a compressed state, and the annular bevel 38 is used, 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 plate 35 will rotate along the annular bevel 38 during the downward movement. When the switching plate 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 material, 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 water and fertilizer spraying can be avoided, ensuring that the device can work normally and improving the practicality of the device.

[0023] 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 water and fertilizer supply. At this time, the blocked circular hole 36 will move to just below the push rod 46, and then the electromagnet 44 will be energized, so that like magnetic poles are generated between the electromagnet 44 and the permanent magnet 45. Under the action of the 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.

[0024] 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 other side wall of the mixing tank 1. The input end of the water pump 23 is fixedly connected to a water pumping pipe 24.

[0025] One end of the water pumping pipe 24 passes through the side walls of the preparation 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 preparation tank 1 and is evenly fixedly connected to multiple water supply pipes 25. 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 preparation 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.

[0026] The inner wall of the first installation box 29 is symmetrically rotatably connected with 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 preparation tank 1 in sequence and then is rotatably connected to the inner wall of the preparation tank 1. The two rotating rods 210 are located between the first hopper 21 and the second hopper 22.

[0027] A section of the side wall of each rotating rod 210 located inside the preparation tank 1 is fixedly connected to a crushing roller 213, a section of the side wall of the rotating rod 210 located in the first installation box 29 is fixedly connected to a vortex blade 211, 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 drain pipe 214, and one end of the drain pipe 214 is fixedly connected to the top wall of the water storage tank 27.

[0028] In this solution, by setting 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 put in through the feed pipe 11, the water pump 23 is started, and the one-way valve 26 is in a closed state at this time, 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, wherein the water flow input into the first installation box 29 is a high-pressure water flow, and the high-pressure water flow will pass between the two vortex blades 211, and the impact force generated by the high-pressure water flow will drive the two vortex blades 211 to rotate, so that the rotating rod 210 The water flows through the two vortex blades 211 and the crushing rollers 213 in the opposite direction. 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 flow cycle, which continuously impacts the vortex blades 211, causing the two vortex blades 211 to rotate, thereby driving the two crushing rollers 213 to rotate. Then, under the action of the first hopper 21, the solid fertilizer is centrally guided, so that the solid fertilizer falls between the two rotating crushing rollers 213, and the solid fertilizer is crushed so that it can be quickly dissolved in water, thereby improving the mixing efficiency. When the solid fertilizer is put in and water supply is needed, it is only necessary to open the one-way valve 26. Thus, the water in the water storage tank 27 is pumped out along the pumping pipe 24 under the action of the water pump 23, and is discharged through multiple water supply pipes 25. It enters the bottom of the mixing tank 1 through the first hopper 21 and the second hopper 22, and is mixed 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, the 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, thereby saving energy consumption and improving the use effect of the device.

[0029] In order to solve the problem that the water and fertilizer in the mixing tank 1 will be sprayed to the outside after the mixing is completed, 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 - Fig.10 As shown, the following preferred technical solutions are provided: 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 preparation 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 the multiple telescopic rods 33 are commonly fixedly connected to a switching disk 35.

[0030] The top of the turntable 32 is symmetrically fixedly connected with a first spring 34, 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 the inner wall of the switching disk 35 is provided with a plurality of circular holes 36 at equal angles. The inner bottom wall of the second installation box 31 is fixedly connected with a discharge pipe 37, and one end of the discharge pipe 37 and the feed pipe 12 are located inside the same circular hole 36.

[0031] One end of the feed pipe 12 and the discharge pipe 37 are both made of rubber. Slide blocks 39 are fixedly connected to the side wall of the switching plate 35 at equal angles. An annular inclined groove 38 is opened on the inner wall of the second installation box 31, and each slide block 39 is located inside the annular inclined groove 38.

[0032] In this scheme, the prepared water and fertilizer are pressurized so that the water and fertilizer inside the preparation tank 1 are discharged along the feeding pipe 12. If the circular hole 36 between the feeding pipe 12 and the discharge pipe 37 is blocked, the water pressure between the circular hole 36 and the feeding pipe 12 will increase, thereby causing the switching plate 35 to move downward. During the downward movement of the switching plate 35, the telescopic rod 33 and the first spring 34 are both in a compressed state, and the annular inclined groove 38 is used, wherein the initial position of the slider 39 is located at the highest point of the annular inclined groove 38. When the water pressure inside the circular hole 36 increases, the switching plate 35 will rotate along the annular inclined groove 38 during its downward movement. When the switching plate 35 slides to the lowest position of the annular inclined groove 38, the elastic action of the first spring 34 Under the action of the pressure relief valve 35, the switch disk 35 is pushed upward to switch the blocked circular hole 36 and the unblocked circular hole 36 of the switch disk 35. During the position switching process of the circular hole 36 of the switch 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 material, there will be no limiting effect during the movement of the switch 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 water and fertilizer spraying can be avoided, thereby ensuring that the device can work normally and improving the practicality of the device.

[0033] In order to solve the technical problem that even if the anti-blocking component 3 is set to prevent the connection between the feed 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 Fig.11 - Fig.12 As shown, the following preferred technical solutions are provided: 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 with a second spring 42. The two second springs 42 are commonly fixedly connected with a connecting plate 43. The top of the connecting plate 43 is fixedly connected with a permanent magnet 45.

[0034] An electromagnet 44 is fixedly connected to the bottom end of the bracket 41, a push rod 46 is fixedly connected to the bottom end of the connecting plate 43, a through hole 47 is opened on the bottom wall of the second installation box 31, and the push rod 46 is slidably connected with the top end of the second installation box 31, the circular hole 36 and the through hole 47.

[0035] In this solution, the anti-blocking component 3 is used to rotate the switching disk 35, and the blocked circular hole 36 is moved, so that the unblocked circular hole 36 connects 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 will be energized, so that the electromagnet 44 and the permanent magnet 45 will generate the same magnetic poles. Under the action of magnetic repulsion, the connecting plate 43 and the push rod 46 are pushed down. 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 continued 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.
