[0002] Integrated water and fertilizer management is an agricultural technology that integrates irrigation and fertilization. This technology uses a pipeline irrigation system to dissolve fertilizers in water and simultaneously performs irrigation and fertilization to meet the water and nutrient requirements of crops timely and in appropriate amounts. Compared with traditional irrigation and fertilization methods, it can save a large amount of water resources and chemical fertilizers. When adding fertilizers, they are generally mixed with water in a water tank.

[0003] However, the existing fertilizer adding devices for integrated water and fertilizer management generally only have a stirring and mixing function, cannot automatically add fertilizers, let alone automatically proportion them. They require manual addition of fertilizers into the water tank and manual proportioning, which has a high labor intensity. Moreover, manual labor cannot work all the time, which may affect the operation of integrated water and fertilizer management.

[0004] To solve this technical problem, the utility model proposes a fertilizer automatic adding device for integrated water and fertilizer management. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a fertilizer automatic adding device for integrated water and fertilizer management, which can effectively solve the problems mentioned in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0014] Compared with the prior art, the present utility model has the following beneficial effects:

[0015] In the present utility model, by providing a spiral push rod inside the feeding pipe, the fertilizer inside the feeding pipe can be pushed into the weighing box. By providing a weighing plate inside the rotating plate, the fertilizer inside the weighing box can be weighed. Specifically, the required weight of the fertilizer is set through the controller. The fertilizer in the storage box falls into the feeding pipe through the feeding hopper. The controller starts the rotation of the first servo motor. The rotation of the first servo motor drives the spiral push rod to rotate, so as to push the fertilizer inside the feeding pipe into the weighing box, and then it is weighed by the weighing plate. When the value on the weighing plate reaches the set value, the controller will stop the first servo motor at this time, and then start the electric push rod, so as to open the rotating plate, and enable all the fertilizer inside the weighing box to slide into the water tank, thus completing automatic fertilization and being able to accurately control the content of the fertilizer.

[0016] In the present utility model, by providing a water pump, the controller can control the water pump to pump water into the water tank. By providing a water level detection tube and an electronic water level gauge, the electronic water level gauge can detect the water level of the water tank, so as to know the water volume. When the electronic water level gauge reaches the set value, the controller will stop the water pump from pumping water at this time, so as to determine the water volume in the water tank. By mixing and stirring with the determined amount of fertilizer, automatic proportioning can be realized, thus ensuring the accurate application of the fertilizer and improving the utilization rate of the fertilizer.
