Description

Technical Field

[0001] This invention relates to the field of water and fertilizer regulation technology, and more specifically, to a water and fertilizer regulation device and method for pear trees. Background Technology

[0002] Water and fertilizer regulation equipment is an intelligent system used in agricultural production to achieve precise control and scientific allocation of water resources and fertilizers. By integrating technologies such as sensors, automated control, and the Internet of Things, it automatically or semi-automatically adjusts the amount of irrigation water, fertilizer, and their ratio according to crop growth needs, soil conditions, and environmental factors, thereby achieving the goals of water conservation, fertilizer conservation, and improved crop yield and quality.

[0003] However, existing water and fertilizer regulation equipment still has some shortcomings in practical applications. When planting pear trees in southern regions, pear trees are mostly planted in hilly areas, and the height difference of the planting location is large, which easily leads to poor precision in water and fertilizer regulation and makes it unable to adapt to complex terrain. Therefore, it is necessary to solve this problem. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the aforementioned technical problems in the prior art. Therefore, one objective of the present invention is to provide a pear tree water and fertilizer regulation device capable of precisely controlling the drip irrigation of water and fertilizer onto pear trees.

[0005] The technical solution of this invention to solve the above-mentioned technical problems is as follows: A pear tree water and fertilizer regulation device, comprising:

[0006] The frame is equipped with a first diversion pipe and a second diversion pipe, with the first diversion pipe positioned above the second diversion pipe. The frame is also equipped with a water and fertilizer pipe, with one end of the water and fertilizer pipe leading to water and fertilizer and the other end connected to the first diversion pipe.

[0007] A water pump is fixedly mounted on the frame. The water pump's inlet end is connected to an inlet pipe, and the water pump's outlet end is connected to a delivery pipe. The delivery pipe is also connected to the second branch pipe.

[0008] Multiple outlet tubes are provided, one end of each outlet tube is connected to the first branch tube and the second branch tube respectively; the other end is connected to the drip irrigation tube; each outlet tube is equipped with a solenoid valve and a flow meter;

[0009] An electrical control box is fixedly mounted on the frame and located on one side of the water pump; the electrical control box is electrically connected to the water pump.

[0010] The control box is electrically connected to a plurality of the solenoid valves, a plurality of the flow meters, and an electrical control box.

[0011] The beneficial effects of this invention are: by arranging multiple flow meters and multiple solenoid valves, the water and fertilizer flow of multiple outlet pipes is precisely controlled. The number of outlet pipes is increased according to the slope of the pear tree planting area, so that the drip irrigation pipes connected to different outlet pipes are arranged at different slopes, reducing the height difference between the two ends of the same drip irrigation pipe and reducing the hydraulic pressure difference at different drip outlets of the same drip irrigation pipe, thereby precisely controlling the water and fertilizer in each outlet pipe to flow evenly to the pear tree through the drip irrigation pipe.

[0012] Based on the above technical solution, the present invention can be further improved as follows.

[0013] Furthermore, it also includes:

[0014] The system includes multiple hydraulic sensors, each fixedly positioned on a corresponding outlet tube, with the sensing end of each sensor extending into its corresponding outlet tube; all hydraulic sensors are electrically connected to the control box.

[0015] Multiple hydraulic sensors are used to sense the hydraulic pressure in the outlet pipe and generate a sensing signal that is transmitted to the control box. The control box processes the sensing signal. When the hydraulic pressure in the outlet pipe is lower than a set first threshold, a first control signal is generated and transmitted to the solenoid valve on the outlet pipe, and the solenoid valve is closed. At the same time, a second control signal is generated and transmitted to the electrical control box. The electrical control box controls the water pump to adjust its speed according to the second control signal.

[0016] When the hydraulic pressure in the outlet pipe is higher than the set second threshold, a third control signal is generated and transmitted to the solenoid valve on the outlet pipe, and the solenoid valve is closed. At the same time, a fourth control signal is generated and transmitted to the electrical control box, which controls the water pump to adjust its speed according to the fourth control signal.

[0017] The beneficial effects of adopting the above-mentioned further solution are: the hydraulic sensor, control box, electrical control box, water pump and solenoid valve work in coordination to accurately monitor the hydraulic pressure in the outlet pipe, prevent water and fertilizer waste, and remind operators to perform timely maintenance; it can also avoid damage to the outlet pipe and its connected drip irrigation pipe caused by excessive hydraulic pressure.

[0018] Furthermore, it also includes:

[0019] A reset button is fixedly placed on the upper end of the hydraulic sensor and electrically connected to the control box. The reset button generates a button signal that is transmitted to the control box. The control box generates a fifth control signal based on the button signal and transmits it to the solenoid valve on the outlet pipe. The solenoid valve is then turned on. The control box also generates a sixth control signal based on the button signal and transmits it to the electrical control box. The electrical control box controls the water pump to adjust its speed based on the sixth control signal.

[0020] The beneficial effects of adopting the above-mentioned further solution are: by pressing the reset button, maintenance personnel are spared the need to climb slopes to adjust the solenoid valve and water pump, reducing labor intensity and improving convenience.

[0021] Furthermore, it also includes:

[0022] The system includes multiple mixing tubes, with one end of each outlet tube connected to the first and second branch tubes via a mixing tube.

[0023] The beneficial effects of adopting the above-mentioned further solutions are: the mixing pipe makes the water and fertilizer dilution and mixing more uniform, and reduces the blockage or deposition of water and fertilizer in the pipe.

[0024] Furthermore, the mixing tube includes:

[0025] The main pipe has a first input end at its upper end, which is fixedly connected to the first shunt pipe; a second input end at its lower end, which is fixedly connected to the second shunt pipe; and an output end on the side wall of the main pipe, which is fixedly connected to the outlet pipe.

[0026] A first input tube is placed inside the main tube, and the upper end of the first input tube is fixedly connected to the first input end; a plurality of flow holes are arranged on the side wall of the first input tube.

[0027] The second input tube is placed inside the main tube, and its lower end is fixedly connected to the second input end; the upper end of the second input tube is connected to the lower end of the first input tube.

[0028] The beneficial effects of adopting the above-mentioned further scheme are: the water and fertilizer and clean water are mixed and diluted in the first input pipe. The hydraulic pressure in the first input pipe is greater than that in the main pipe, which can improve the mixing efficiency of water and fertilizer, so that the water and fertilizer flow irregularly in the first input pipe and improve the uniformity of water and fertilizer mixing.

[0029] Furthermore, the diameter of the first input tube gradually decreases from top to bottom; the diameter of the second input tube gradually decreases from bottom to top, and a connecting tube is fixedly connected to the upper end of the second input tube, and the second input tube is fixedly connected to the first input tube through the connecting tube.

[0030] The beneficial effects of adopting the above-mentioned further scheme are: the diameter of the first input pipe gradually decreases from top to bottom, which can increase the flow rate of water and fertilizer; the diameter of the second input pipe gradually decreases from bottom to top, which can increase the flow rate of clean water; when water and fertilizer and clean water are mixed and diluted in the first and second input pipes, the mixing efficiency is higher and the mixing and dilution is more uniform; increasing the flow rate and water pressure can also prevent fertilizer in the water and fertilizer from depositing or clogging in the first input pipe.

[0031] Furthermore, the mixing tube also includes:

[0032] Multiple guide vanes are arranged sequentially along the inner wall of the second input pipe and are fixedly connected to the inner wall of the second input pipe; the ends of two adjacent guide vanes are stacked close to each other.

[0033] The beneficial effects of adopting the above-mentioned further solution are: the guide plate makes the water flow subject to force, and the water flow forms a wave during the process of flowing into the first input pipe. The wave of clear water flow and fertilizer water flow are more easily mixed evenly in the first input pipe, improving dilution efficiency and uniformity.

[0034] Furthermore, the mixing tube also includes:

[0035] Multiple blades are fixedly placed on the inner wall of the first input tube, and the multiple blades are arranged at equal intervals along the inner wall of the first input tube.

[0036] The beneficial effect of adopting the above-mentioned further solution is that by arranging multiple flow meters and multiple solenoid valves to precisely control the water and fertilizer flow of multiple outlet pipes, the water and fertilizer in each outlet pipe can be precisely controlled to flow evenly to the pear trees through the drip irrigation pipe.

[0047] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0048] like Figures 1 to 6 As shown, a water and fertilizer regulation device for pear trees includes:

[0049] A frame 1 is provided, on which a first diversion pipe 2 and a second diversion pipe 3 are fixedly installed, with the first diversion pipe 2 positioned above the second diversion pipe 3; a water-fertilizer pipe 4 is also provided on the frame 1, with one end of the water-fertilizer pipe 4 leading to water and fertilizer, and the other end connected to the first diversion pipe 2.

[0050] Water pump 5 is fixedly mounted on the frame 1. The water inlet end of the water pump 5 is connected to the water inlet pipe 6, and the water outlet end of the water pump 5 is connected to the water delivery pipe 7. The water delivery pipe 7 is also connected to the second diversion pipe 3.

[0051] Multiple outlet tubes 8 are provided, one end of each outlet tube 8 is connected to the first branch tube 2 and the second branch tube 3 respectively; the other end is connected to the drip irrigation tube; each outlet tube 8 is equipped with a solenoid valve 9 and a flow meter 10;

[0052] An electrical control box 11 is fixedly mounted on the frame 1 and is located on one side of the water pump 5; the electrical control box 11 is electrically connected to the water pump 5.

[0053] The control box 12 is fixedly placed on the frame 1 and located above the electrical control box 11. The control box 12 is electrically connected to a plurality of solenoid valves 9, a plurality of flow meters 10, and the electrical control box 11.

[0054] In this specific application, the electrical control box 11 controls the water pump 5 to operate. The water pump 5 introduces water flow through the inlet pipe 6 and delivers the water flow through the water supply pipe 7 to the second branch pipe 3. The second branch pipe 3 delivers the water flow to the outlet pipe 8. At the same time, the water-fertilizer pipe 4 introduces high-concentration water-fertilizer and delivers the water-fertilizer to the first branch pipe 2. The first branch pipe 2 delivers the water-fertilizer to the outlet pipe 8. The water-fertilizer is diluted in the outlet pipe 8. After the control box 12 controls the solenoid valve 9 to open, the water-fertilizer is delivered to the drip irrigation pipe for drip irrigation. When the flow rate measured by the flow meter 10 exceeds the set threshold, a flow signal is generated and transmitted to the control box 12. The control box 12 controls the solenoid valve 9 to close.

[0055] This embodiment uses multiple flow meters 10 and multiple solenoid valves 9 to precisely control the water and fertilizer flow of multiple outlet pipes 8. The number of outlet pipes 8 is increased according to the slope of the pear tree planting area, so that the drip irrigation pipes connected to different outlet pipes 8 are arranged at different slopes, reducing the height difference between the two ends of the same drip irrigation pipe and reducing the hydraulic pressure difference at different drip outlets of the same drip irrigation pipe. This allows for precise control of the water and fertilizer in each outlet pipe 8 to flow evenly to the pear trees through the drip irrigation pipe.

[0056] The above embodiments also include:

[0057] Hydraulic sensors 13 are provided in multiple ways. Each hydraulic sensor 13 is fixedly placed on one of the multiple outlet pipes 8. The sensing end of each hydraulic sensor 13 extends into its corresponding outlet pipe 8. All hydraulic sensors 13 are electrically connected to the control box 12.

[0058] Multiple hydraulic sensors 13 are used to sense the hydraulic pressure in the outlet pipe 8 and generate a sensing signal that is transmitted to the control box 12. The control box 12 processes the sensing signal. When the hydraulic pressure in the outlet pipe 8 is lower than a set first threshold, a first control signal is generated and transmitted to the solenoid valve 9 on the outlet pipe 8, and the solenoid valve 9 is closed. At the same time, a second control signal is generated and transmitted to the electrical control box 11. The electrical control box 11 controls the water pump 5 to adjust its speed according to the second control signal.

[0059] When the hydraulic pressure in the outlet pipe 8 is higher than the set second threshold, a third control signal is generated and transmitted to the solenoid valve 9 on the outlet pipe 8, and the solenoid valve 9 is closed. At the same time, a fourth control signal is generated and transmitted to the electrical control box 11. The electrical control box 11 controls the water pump 5 to adjust its speed according to the fourth control signal.

[0060] In this specific application, multiple outlet pipes 8 and their connected drip irrigation pipes are arranged at different slopes. When the outlet pipes 8 and their connected drip irrigation pipes become blocked or leak, it can easily lead to water and fertilizer waste and energy loss. Most importantly, it can also damage the blocked outlet pipes 8. After the water and fertilizer delivery begins, the hydraulic sensor 13, control box 12, electrical control box 11, water pump 5, and solenoid valve 9 work in coordination to accurately monitor the hydraulic pressure in the outlet pipes 8. When the hydraulic pressure in the outlet pipes 8 is too low, it is considered that the outlet pipes 8 and their connected drip irrigation pipes are leaking. At the same time, the outlet pipes 8 are controlled to close, which can prevent water and fertilizer waste and remind the operators to perform timely maintenance. It can also control the water pump 5 to adjust its speed to reduce energy consumption. When the hydraulic pressure in the outlet pipes 8 is too high, it is considered that the outlet pipes 8 and their connected drip irrigation pipes are blocked. At the same time, the outlet pipes 8 are controlled to close, which can prevent the excessive hydraulic pressure from damaging the outlet pipes 8 and their connected drip irrigation pipes and remind the operators to perform timely maintenance. It can also control the water pump 5 to adjust its speed to reduce energy consumption.

[0061] The above embodiments also include:

[0062] A reset button 14 is fixedly placed on the upper end of the hydraulic sensor 13 and electrically connected to the control box 12. The reset button 14 is used to generate a button signal and transmit it to the control box 12. The control box 12 generates a fifth control signal based on the button signal and transmits it to the solenoid valve 9 on the outlet pipe 8. The solenoid valve 9 is turned on. The control box 12 also generates a sixth control signal based on the button signal and transmits it to the electrical control box 11. The electrical control box 11 controls the water pump 5 to adjust its speed based on the sixth control signal.

[0063] In a specific application of this embodiment, when the outlet pipe 8 and its connected drip irrigation pipe malfunction and require maintenance, pressing the reset button 14 generates a button signal that is transmitted to the control box 12. The control box 12 then controls the solenoid valve 9, the electrical control box 11, and the water pump 5 to operate, thereby enabling the solenoid valve 9 to conduct and simultaneously controlling the water pump 5 to resume its speed. This avoids the need for maintenance personnel to climb slopes to adjust the solenoid valve 9 and the water pump 5, reducing labor intensity and improving convenience.

[0064] The above embodiments also include:

[0065] Mixing pipe 15, multiple mixing pipes 15 are provided, and one end of each outlet pipe 8 is connected to the first branch pipe 2 and the second branch pipe 3 through a mixing pipe 15.

[0066] In a specific application of this embodiment, the water and fertilizer introduced by the first diversion pipe 2 and the clean water introduced by the second diversion pipe 3 are mixed in the mixing pipe 15. The mixing pipe 15 makes the water and fertilizer more uniformly diluted and mixed, reducing the blockage or deposition of water and fertilizer in the pipe.

[0067] In the above embodiments, the mixing tube 15 includes:

[0068] The main pipe 1501 has a first input terminal at its upper end, which is fixedly connected to the first branch pipe 2. The main pipe 1501 has a second input terminal at its lower end, which is fixedly connected to the second branch pipe 3. The main pipe 1501 has an output terminal on its side wall, which is fixedly connected to the outlet pipe 8.

[0069] The first input tube 1502 is placed inside the main tube 1501, and the upper end of the first input tube 1502 is fixedly connected to the first input end; a plurality of flow holes are arranged on the side wall of the first input tube 1502.

[0070] The second input tube 1503 is placed inside the main tube 1501, and the lower end of the second input tube 1503 is fixedly connected to the second input end; the upper end of the second input tube 1503 is connected to the lower end of the first input tube 1502.

[0071] In this specific application, the first input end introduces water and fertilizer through the first branch pipe 2, and the second input end introduces clean water through the second branch pipe 3. The water and fertilizer and clean water are mixed and diluted in the first input pipe 1502. The diluted water and fertilizer flow out through multiple flow holes to the main pipe 1501 for mixing again and then out to the output pipe 8. During the mixing process of water and fertilizer in the first input pipe 1502, the hydraulic pressure in the first input pipe 1502 is greater than the hydraulic pressure in the main pipe 1501, which can improve the mixing efficiency of water and fertilizer, so that water and fertilizer flow irregularly in the first input pipe 1502, thereby improving the uniformity of water and fertilizer mixing.

[0072] In the above embodiment, the diameter of the first input tube 1502 gradually decreases from top to bottom; the diameter of the second input tube 1503 gradually decreases from bottom to top, and a connecting tube is fixedly connected to the upper end of the second input tube 1503, and the second input tube 1503 is fixedly connected to the first input tube 1502 through the connecting tube.

[0073] In this specific application, the diameter of the first input pipe 1502 gradually decreases from top to bottom, which can increase the flow rate of water and fertilizer. The diameter of the second input pipe 1503 gradually decreases from bottom to top, which can increase the flow rate of clean water. When water, fertilizer and clean water are mixed and diluted in the first input pipe 1502 and the second input pipe 1503, the mixing efficiency is higher and the mixing and dilution is more uniform. Increasing the flow rate and water pressure can also prevent fertilizer in the water and fertilizer from depositing or clogging in the first input pipe 1502.

[0074] In the above embodiments, the mixing tube 15 further includes:

[0075] Multiple guide vanes 1504 are arranged sequentially along the inner wall of the second input pipe 1503 and are fixedly connected to the inner wall of the second input pipe 1503; the ends of two adjacent guide vanes 1504 are stacked close to each other.

[0076] In this specific application, the guide plate 1504 is a plastic sheet. Under the water pressure of the water flow, the guide plate 1504 swings. The guide plate 1504 causes the water flow to be subjected to force. During the process of the water flow flowing into the first input pipe 1502, a wave is formed. The wave of clean water flow and fertilizer water flow is more easily mixed evenly in the first input pipe 1502, improving dilution efficiency and uniformity.

[0077] In the above embodiments, the mixing tube 15 further includes:

[0078] Multiple blades are fixedly placed on the inner wall of the first input tube 1502, and the multiple blades are arranged at equal intervals along the inner wall of the first input tube 1502.

[0079] In practical application of this embodiment, multiple blades facilitate the cutting of undissolved fertilizer or debris in the water and fertilizer, avoiding blockage of the first input pipe 1502 or drip irrigation, and ensuring efficient operation.

[0080] like Figure 7 As shown, a method for regulating water and fertilizer in pear trees includes the following steps:

[0081] The electrical control box 11 controls the water pump 5 to operate. The water pump 5 introduces water flow through the inlet pipe 6 and discharges the water flow through the water delivery pipe 7 to the second branch pipe 3. The second branch pipe 3 then delivers the water flow to the outlet pipe 8.

[0082] At the same time, water and fertilizer pipe 4 introduces high-concentration water and fertilizer, and water and fertilizer pipe 4 discharges water and fertilizer to the first branch pipe 2; the first branch pipe 2 transports water and fertilizer to the discharge pipe 8.

[0083] The water and fertilizer are diluted in the outlet pipe 8. After the control box 12 controls the solenoid valve 9 to open, the water and fertilizer are exported to the drip irrigation pipe for drip irrigation. When the flow measured by the flow meter 10 exceeds the set threshold, a flow signal is generated and transmitted to the control box 12. The control box 12 controls the solenoid valve 9 to close.

[0084] In a specific application of this embodiment, multiple flow meters 10 and multiple solenoid valves 9 are arranged to precisely control the water and fertilizer flow of multiple outlet pipes 8. The number of outlet pipes 8 is increased according to the slope of the pear tree planting area, so that the drip irrigation pipes connected to different outlet pipes 8 are arranged at different slopes, reducing the height difference between the two ends of the same drip irrigation pipe and reducing the hydraulic pressure difference at different drip outlets of the same drip irrigation pipe, thereby precisely controlling the water and fertilizer in each outlet pipe 8 to flow evenly to the pear tree through the drip irrigation pipe.

[0085] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
