[0002] my country is a major agricultural country, and the vigorous promotion of integrated water and fertilizer technology (IWC) involves using pipeline irrigation systems to dissolve fertilizer in water, simultaneously irrigating and fertilizing. This meets the timely and appropriate water and nutrient needs of crops, achieving synchronized water and fertilizer management and efficient utilization. The development of new rural areas and intensive agricultural production are the future directions for my country's rural and agricultural sectors. Modernizing agricultural equipment is a crucial means to achieve agricultural modernization. Coupled with the large-scale transfer of rural labor, precision fertilization and controlled fertilization technologies will be vigorously promoted and widely applied.

[0029] The liquid fertilizer applicator provided in this application, such as Figures 1 to 4 As shown, it includes fertilizer inlet pipe 3, water inlet pipe 2, delivery pump 9, and fertilizer application pipe 1.

[0030] The fertilizer inlet pipe 3 is connected at its inlet end to a liquid fertilizer source, such as a liquid fertilizer storage tank, to draw in liquid fertilizer. Its outlet end is connected to the inlet end of the delivery pump 9. The liquid fertilizer drawn in by the fertilizer inlet pipe 3 enters the delivery pump 9 for pressurized delivery, improving fertilization speed and irrigation efficiency. The delivery pump 9 is preferably a diaphragm pump. A conventional liquid storage device can be used for the liquid fertilizer storage tank, which will not be elaborated upon here.

[0031] The outlet end of the delivery pump 9 is connected to the inlet end of the fertilizer pipe 1; the outlet end of the fertilizer pipe 1 is used to discharge liquid fertilizer for fertilization, and the outlet end of the fertilizer pipe 1 can be connected to the irrigation water circuit, so that the liquid fertilizer can be directly delivered to the irrigation water circuit for fertilization.

[0032] A fertilizer inlet pipe 3 is equipped with a fertilizer valve 4, and a flow meter 7 is equipped on the fertilizer pipe 1. By setting the fertilizer valve 4 and the flow meter 7, fertilization can be controlled and the fertilization speed can be adjusted, reducing power consumption and saving labor and material costs. The flow meter 7 is preferably an electromagnetic flow meter, which is accurate in measurement.

[0033] The fertilizer pipe 1 is also equipped with a check valve 8, which can prevent backflow of liquid fertilizer and water in the irrigation water circuit connected to the fertilizer pipe, ensuring one-way delivery of liquid fertilizer and further improving delivery speed.

[0034] Preferably, the check valve 8 is positioned close to the delivery pump 9, while the flow meter 7 is positioned away from the delivery pump 9. This ensures that the liquid fertilizer is prevented from flowing back while avoiding the flow meter electrodes being immersed in the fertilizer solution for a long time. At the same time, the longitudinal placement of the check valve 8 shortens the lateral installation distance to meet the installation specifications of the flow meter 7, thereby further reducing the size.

[0035] The inlet end of the water inlet pipe 2 is connected to a water source such as an irrigation system, while the other end is connected to the inlet end of the delivery pump 9 and the fertilizer inlet pipe 3. Because liquid fertilizer has a high nutrient content, it is prone to precipitation during transport, clogging pipes, valves, pumps, and flow meters, while also causing nutrient loss and affecting fertilization efficiency. This application addresses this issue by installing the water inlet pipe 2. When cleaning is required, water from the inlet pipe can enter the delivery pump, fertilizer pipe, check valve, and flow meter to flush away sediment in the fertilizer pipe. It can also enter the fertilizer inlet pipe to flush away sediment, reducing pipe blockage. Furthermore, since the flow meter is located on the fertilizer pipe, it can flush away liquid fertilizer measured by the flow meter during cleaning, improving nutrient utilization and fertilization accuracy.

[0036] A cleaning valve 5 is installed on the water inlet pipe 2 to control the cleaning process. The fertilization valve 4 and the cleaning valve 5 allow for easy switching between fertilization and self-cleaning. Preferably, the fertilization valve and the cleaning valve are electric valves, which can be electrically controlled and do not require manual adjustment.

[0037] A pressure transmitter 6 is preferably installed on the water inlet pipe 2. This facilitates adjustment of the cleaning water pressure and improves the cleaning effect.

[0038] Preferably, the outlet end of the water inlet pipe 2 is connected to the outlet end of the fertilizer inlet pipe 3. That is, the cleaning water flows from the outlet of the water inlet pipe to the inlet, which can easily flush the sediment out of the system and prevent the sediment from flowing forward and depositing on the transfer pump 9.

[0039] More preferably, the outlet end of the water inlet pipe 2, the outlet end of the fertilizer inlet pipe 3, and the inlet end of the delivery pump 9 are connected by a T-junction.

[0040] Preferably, quick-connect interfaces are provided at both ends of components such as fertilizer inlet pipe, water inlet pipe, delivery pump, fertilizer application pipe, fertilizer valve, cleaning valve, flow meter and check valve to facilitate connection and disassembly of each component.

[0041] Preferably, the fertilizer applicator of this application also includes a housing, with the main bodies of the fertilizer inlet pipe, water inlet pipe, and fertilizer application pipe, as well as components such as the delivery pump, all located inside the housing. The inlet ends of the fertilizer inlet pipe, water inlet pipe, and fertilizer application pipe are located outside the housing, facilitating connection to the liquid fertilizer storage tank, irrigation water system, and fertilization. The housing provides comprehensive protection for the fertilizer applicator, extending its service life.

[0042] Therefore, the liquid fertilizer applicator provided in this application can achieve rapid liquid fertilizer application and self-cleaning on a standalone basis. It allows for adjustable application speed for precise control, improving irrigation efficiency. Suitable for drip irrigation systems, it reduces power consumption and saves labor and material costs. Furthermore, it enhances nutrient utilization and fertilization effectiveness. Moreover, the applicator features a simple structure, ingenious design, and small size, making it suitable for large-scale application.

Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the present invention. Clearly, those skilled in the art can make various alterations and modifications to the present invention without departing from its spirit and scope. Thus, if such modifications and modifications fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include such modifications and modifications.
