Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0036] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0037] Embodiment 1

[0038] Please refer to Figures 1-3, the present invention provides a technical solution: a fertilization and irrigation integrated device, including a mounting frame 1. The mounting frame 1 includes a bottom frame 11, which is the installation foundation of the entire device. Two circular through holes are opened at the top of the bottom frame 11. A support plate is fixedly connected to the right side of the bottom frame 11. A pump support 12 is fixedly connected to the top of the bottom frame 11. A water tank support 13 is fixedly connected to the top of the pump support 12. A rectangular through hole is opened on the left side of the water tank support 13;

[0039] A water diversion tank 2 is fixedly connected to the top of the water tank support 13. The water diversion tank 2 is made of stainless steel. The water diversion tank 2 includes a pressurization tank 21, which is used for diverting irrigation water and pressurizing it when the flow rate decreases. The bottom of the pressurization tank 21 is fixedly connected to the bottom of the rectangular through hole of the water tank support 13. The pressurization tank 21 includes a box body 211. The bottom of the box body 211 is fixedly connected to the bottom of the rectangular through hole of the water tank support 13. A flange is connected to the left side of the box body 211 for connecting an external water supply device. A circular through hole is opened at the top of the box body 211. Two circular through holes are opened at the bottom of the box body 211. The bottom of the box body 211 is fixedly connected to the bottom of the rectangular through hole of the water tank support 13. A pressurization plate 212 is slidably connected to the left side inside the box body 211. A rubber sealing frame 213 is fixedly connected to the top of the pressurization plate 212 for sealing the gap at the junction of the box body 211 and the pressurization plate 212. The push rod at the bottom of the electric pressurization push rod 22 is fixedly connected to the top of the pressurization plate 212 through the circular through hole at the top of the box body 211. An electric pressurization push rod 22 is fixedly connected to the top of the rectangular through hole of the water tank support 13. The push rod at the bottom of the electric pressurization push rod 22 is slidably connected. The electric pressurization push rod 22 is electrically connected to the electric control cabinet 7 through a wire. A flow rate sensor 23 is connected to the through hole near the left side at the bottom of the box body 211. The flow rate sensor 23 is electrically connected to the electric control cabinet 7 through a wire. The bottom of the flow rate sensor 23 is connected to an L-shaped metal pipe, which is used to detect the water flow rate flowing into the compensation irrigation mechanism 6, and thus detect the water flow rate in the pressurization tank 21. The surface of the L-shaped metal pipe is fixedly connected to the support plate on the right side of the bottom frame 11;

[0040] A water pump assembly 3 is fixedly connected to the top of the pump support 12, which is used to introduce irrigation water into the liquid fertilizer mixing tank 4. The water pump assembly 3 is located on the right side of the pump support 12. The top of the water pump assembly 3 is connected to the circular through hole near the right side at the bottom of the box body 211. The right side of the water pump assembly 3 is connected to a liquid fertilizer mixing tank 4, which is used to mix irrigation water and fertilizer into liquid fertilizer. The water pump assembly 3 is electrically connected to the electric control cabinet 7 through a wire;

[0041] A liquid fertilizer mixing tank 4 is fixedly connected to the top of the bottom frame 11. The right side of the liquid fertilizer mixing tank 4 is connected to a liquid fertilizer spraying mechanism 5. A compensation irrigation mechanism 6 is fixedly connected to the right side of the bottom frame 11. An electric control cabinet 7 is fixedly connected to the front of the bottom frame 11.

[0042] During use, connect an external water supply device to the flange on the left side of the box body 211, add fertilizer raw materials into the liquid fertilizer mixing bin 4, and then start the device through the electric control cabinet 7. The external irrigation water enters the box body 211 through the flange. Subsequently, a part of the irrigation water is sucked into the liquid fertilizer mixing bin 4 by the water pump assembly 3 and is stirred and mixed with the fertilizer to form liquid fertilizer. Finally, it is sprayed onto the land where the crops are located through the liquid fertilizer spraying mechanism 5. Another part passes through the flow rate sensor 23 and the L-shaped metal pipe and enters the supplementary irrigation mechanism 6. When the external environmental factors change and it is necessary to reduce the fertilizer concentration, the irrigation water is sprayed out of the device and finally mixed with the liquid fertilizer sprayed by the liquid fertilizer spraying mechanism 5 to achieve the compensation dilution of the liquid fertilizer concentration and the supplementary irrigation of water;

[0043] During this process, the flow rate sensor 23 transmits the detected flow rate data to the electric control cabinet 7 in real time. When the water flow rate passing through the flow rate sensor 23 decreases, the electric control cabinet 7 adjusts the flow rate data according to the flow rate data fed back by the flow rate sensor 23 and controls the push rod of the electric pressure push rod 22 to slide downward. The push rod of the electric pressure push rod 22 drives the pressure plate 212 to slide downward, and the actual volume inside the box body 211 decreases. When the water inlet speed of the water supply device remains unchanged per unit time, the water pressure entering the box body 211 increases, thereby increasing the water flow rate and preventing the insufficient water flow rate of the subsequent irrigation water from affecting the irrigation effect.
