[0001] The invention belongs to the technical field of agricultural fertilization, and in particular relates to an automatic opening and closing water-fertilizer integrated device. Background Art

[0002] Fertilization in agricultural production is a necessary condition to ensure the supply of crop nutrients. As the number of young and middle-aged laborers engaged in agricultural work decreases and the aging of agricultural practitioners accelerates, the labor cost consumed by farming and fertilization is getting higher and higher. Therefore, changing the way of agricultural fertilization, reducing labor intensity and reducing labor workload can effectively improve agricultural productivity. Agricultural mechanization and automation are the development trends of agriculture in the future. However, some hilly areas are not suitable for mechanized farming. On the one hand, the fields are small and agricultural machinery cannot work in the fields. On the other hand, there are many hill terraces and most agricultural machinery cannot enter the fields. At present, devices that use automatic control methods for agricultural fertilization have begun to be used in actual production. However, most of these automatic control devices use power lines to control electricity or solar power control, that is, they need to input various energy sources to provide power for control. Most of the existing automatic control devices use electronic control methods. Electronic products are exposed to the sun and rain outdoors, which is prone to failure and their service life is limited. In addition, most electronically controlled automatic fertilization devices are complex to operate and require professional training to operate. Technical personnel are often required to perform maintenance and provide operational guidance, which increases technical service expenditure costs and fails to increase farmers' enthusiasm for adopting automated control.

DETAILED DESCRIPTION

[0022] The embodiments of the present invention are described in detail below. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] Example 1

[0024] The present invention provides an automatic opening and closing water-fertilizer integrated device, comprising a water-fertilizer storage box 1, a water level controller 2, a liquid reservoir 3, a fertilizer controller 4, a fertilizer collector 5, an air intake valve 6, a first connecting pipe 71, a second connecting pipe 72, an air intake pipe 73, a drain pipe 74, an overflow pipe 75 and a fertilizer pipe 76.

[0025] The top of the water-fertilizer storage box 1 is provided with a spiral sealing cover 11 for sealing; the spiral sealing cover 11 can be opened to inject liquid containing various fertilizers, which is called water-soluble fertilizer, into the liquid.

[0026] The top of the water-fertilizer storage box 1 is connected to one end of the air inlet pipe 73 , and the bottom of the water-fertilizer storage box 1 is also connected to one end of the second connecting pipe 72 ; the other end of the air inlet pipe 73 is connected to the air inlet valve 6 .

[0027] The air inlet valve 6 is arranged in the water level controller 2; the air inlet valve 6 includes an air inlet valve pipe 61, a plug, a connecting rod and a floating ball. The top of the air inlet valve pipe is connected to the air inlet pipe 73, the plug is movably arranged in the air inlet valve pipe, and the bottom of the plug is fixedly connected to the floating ball under the connecting rod through the connecting rod. When liquid continuously flows into the water level controller 2, causing the liquid level to continuously rise, the floating ball in the air inlet valve 6 will also continuously float up, and drive the plug to rise through the connecting rod, and finally block the air inlet pipe 73 through the plug, so that no air enters the top of the water and fertilizer storage box 1. Under the influence of atmospheric pressure, the first connecting pipe 71 and the second connecting pipe 72 below cannot discharge the water and fertilizer liquid. When the liquid level in the water level controller 2 gradually decreases, and the floating ball decreases with the liquid level, the air inlet pipe 73 is reopened to intake air to the top of the water and fertilizer storage box 1, and the bottom of the water and fertilizer storage box 1 can discharge the water and fertilizer liquid from the first connecting pipe 71 and the second connecting pipe 72.

[0028] The other end of the second connecting pipe 72 is connected to the upper part of the liquid reservoir 3 .

[0029] A first inverted U-shaped tube 31 passing through the middle of the side wall is fixedly arranged on the side wall of the liquid reservoir 3 , and one end opening of the first inverted U-shaped tube 31 is arranged at the lower part of the liquid reservoir 3 , and the other end opening is arranged at the lower part of the water level controller 2 .

[0030] The bottom of the water level controller 2 is connected to one end of the drain pipe 74, the upper part of the side wall of the water level controller 2 is connected to one end of the overflow pipe 75, and the other ends of the drain pipe 74 and the overflow pipe 75 are both connected to the upper part of the fertilizer controller 4. The upper part of the water level controller 2 is connected to the overflow pipe 75, and when the water level in the water level controller reaches the overflow control line, it starts to be discharged from the overflow pipe to the fertilizer controller, ensuring that the water level of the water level controller is within the overflow line.

[0031] A second inverted U-shaped tube 41 passing through the middle of the side wall is fixedly arranged on the side wall of the fertilizer controller 4, and one end opening of the second inverted U-shaped tube 41 is arranged at the lower part of the fertilizer controller 4, and the other end opening is arranged at the lower part of the fertilizer collector 5.

[0032] A fertilizer pipe 76 is provided at the bottom of the fertilizer collector 5, and the fertilizer pipe 76 transports the water-soluble fertilizer in the fertilizer collector 5 to the field.

[0033] One end of the first connecting pipe 71 is connected to the bottom of the water-fertilizer storage box 1 , and the other end of the first connecting pipe 71 is connected to the upper part of the fertilizer collector 5 .

[0034] The first connecting pipe 71 is provided with a first flow regulating valve 711, and the second connecting pipe 72 is provided with a second flow regulating valve 721. The second flow regulating valve 721 can adjust the speed at which the liquid in the water and fertilizer storage tank 1 enters the liquid reservoir 3. The height of the liquid reservoir 3 is higher than the water level controller 2. When the liquid flowing into the liquid reservoir 3 reaches a certain height, the liquid reservoir will flow to the water level controller 2 through the first inverted U-shaped pipe 31, and then an inverted U-shaped siphon will be formed. The inverted U-shaped siphon can make the water level in the liquid reservoir consistent with the water level in the water level controller.

[0035] The liquid in the liquid reservoir continuously flows into the water level controller, causing the water level of the water level controller to rise. When it rises to the set height, the float of the air inlet valve 6 in the water level controller closes the air inlet pipe through the connecting rod and the plug. At the same time, the float also seals the lower end opening of the air inlet valve pipe, so that the liquid in the water level controller cannot enter the air inlet valve.

[0036] When the air inlet pipe is closed, the air inlet pipe in the water-fertilizer storage box 1 cannot let in air, and under the influence of atmospheric pressure, the liquid discharge pipe in the water-fertilizer storage box 1 cannot discharge liquid outward. Then the water-fertilizer storage box stops flowing liquid into the liquid reservoir. At this time, there is a certain height of liquid in the liquid reservoir, and under the siphon effect formed by the first inverted U-shaped tube 31, liquid still flows into the water level controller, so that the water level of the water level controller reaches the same height as the liquid reservoir. The drain pipe 74 at the bottom of the water level controller discharges the liquid in the water level controller and the liquid reservoir into the fertilization controller.

[0037] The fertilization controller injects liquid into the fertilization collector through the second inverted U-shaped tube 41. When the liquid in the fertilization controller reaches a certain liquid level, it forms an inverted U-shaped siphon with the fertilization collector, thereby discharging the liquid in the fertilization controller to flow to the fertilization collector.

[0038] The liquid discharge pipe 74 is provided with a third flow regulating valve 741 , so as to control the liquid discharge speed of the water level controller 2 .

[0039] A vent hole may also be provided in the middle of the air inlet valve pipe, and a double-layer seal is formed after the liquid level submerges the vent hole.

[0040] The liquid storage container 3 and the first inverted U-shaped tube 31 are integrally formed, and the fertilization controller 4 and the second inverted U-shaped tube 41 are also integrally formed.

[0041] The height of the float in the water level controller 2 is always lower than the position on the side wall of the water level controller 2 connected to the overflow pipe 75; the plug is used to close the air inlet pipe 73.

[0042] The openings at both ends of the second inverted U-shaped tube 41 have different heights, and the height of the opening end arranged in the fertilizer controller 4 is higher than the height of the opening end arranged in the fertilizer collector 5 .

[0043] The height of the bottom of the water-fertilizer storage box 1 is higher than the height of the top of the liquid storage container 3; the height of the bottom of the water level controller 2 is higher than the height of the top of the fertilization controller 4.

[0044] The position where the liquid reservoir 3 is connected to the first inverted U-shaped tube 31 is the highest position in the first inverted U-shaped tube 31 ; the position where the fertilizer controller 4 is connected to the second inverted U-shaped tube 41 is the highest position in the second inverted U-shaped tube 41 .

[0045] When in use, first add a certain amount of water-soluble fertilizer to the water-fertilizer storage box, and the water-soluble fertilizer transports the aqueous solution to the fertilizer collector through the first connecting pipe 71, and the fertilizer collector then transports the water-soluble fertilizer to the field to fertilize the crops. At the same time, the water-soluble fertilizer is also input into the liquid reservoir through the second connecting pipe 72. When the liquid height in the liquid reservoir reaches the height where the first inverted U-shaped tube 31 can flow out by itself, the liquid begins to flow to the water level controller and forms an inverted U-shaped siphon communication vessel, so that the liquid water level of the water level controller rises. As the liquid water level of the water level controller rises, the air inlet valve in the water level controller is triggered to close. After the float at the lower end of the air inlet valve is submerged by water, the air inlet valve pipe in the water level controller forms an air-tight environment, so the air inlet pipe connected to the air inlet valve cannot pass air into the water-fertilizer storage box. When no air is passed into the water-fertilizer storage box, the air pressure in the water-fertilizer storage box is less than the external atmospheric pressure, so the first connecting pipe 71 and the second connecting pipe 72 connected to the water-fertilizer storage box cannot discharge liquid, and the fertilization device is automatically closed. The liquid in the liquid reservoir and the water level controller will reach the same liquid level due to the siphon effect of the inverted U-shaped siphon tube. Then the water-fertilizer solution in the water level controller flows to the fertilization controller through the drainage pipe 74. The fertilization controller can collect a certain amount of water-fertilizer solution. When the water-fertilizer solution exceeds a certain amount, the water-fertilizer solution begins to flow through the second inverted U-shaped pipe 41 to the fertilizer collector and forms a siphon effect. When the amount of water-fertilizer solution set by the fertilizer controller is not reached. The entire fertilization system stops applying water-soluble fertilizer to the field. When the water-fertilizer solution in the water level controller is continuously discharged, the float connecting rod descends with the float, the air inlet valve opens, and the air inlet pipe connected to the water-fertilizer storage box begins to introduce air into the upper part of the water-fertilizer storage box, so that the water-fertilizer storage box begins to flow out liquid through the first connecting pipe 71 and the second connecting pipe 72, realizing the automatic opening state of the fertilization device. The fertilization opening duration and closing duration are adjusted by the flow regulating valves on the first connecting pipe 71, the second connecting pipe 72 and the drainage pipe 74.

[0046] In a specific embodiment, the inner diameter of the first connecting pipe 71 is 2.5 cm and the length is greater than 2 meters, the inner diameter of the second connecting pipe 72 is 2.5 cm and the length is greater than 2 meters, the inner diameter of the air inlet pipe 73 is 6 cm, the inner diameter of the liquid discharge pipe 74 is 2.5 cm, the inner diameter of the overflow pipe 75 is 4 cm, the inner diameters of the first inverted U-shaped pipe 31 and the second inverted U-shaped pipe 41 are both 2.5 cm, the volume of the water and fertilizer storage box 1 is greater than 150L, ​​and the water and fertilizer storage box 1 is cylindrical with a bottom diameter of 60 cm. The height of the water and fertilizer storage box 1 is 30 cm higher than the water level controller, forming a self-flowing height difference. The height of the water level controller is 30 cm higher than the height of the fertilizer controller. The height of the fertilizer controller is 30 cm higher than the height of the fertilizer collector, forming a self-flowing height difference.

[0047] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions and substitutions can be made without departing from the concept of the present invention, which should be regarded as belonging to the protection scope of the present invention.
