Description

Technical Field

[0001] This utility model belongs to the field of agricultural irrigation technology, specifically relating to an agricultural irrigation acidity adjustment device. Background Technology

[0002] In fertigation systems, varying water quality results in different pH values, directly affecting the acidity or alkalinity of fertilizers prepared by the fertilizer applicator, thus impacting crop growth. Therefore, water source control is crucial. Pre-acidifying the water source makes managing the root environment of crops and maintaining a stable pH level much easier. To achieve a stable pH, bicarbonate should be avoided, as it causes the pH to rise. Bicarbonate or OH- increases the pH, while H+ decreases it. Bicarbonate decomposes easily; adding a small amount of nitrate, sulfate, or phosphate can readily acidify the solution. H+ ions react with OH- to form H2O. However, CO2 remains gaseous in water. Therefore, the technical challenge lies in gently shaking the solution to remove CO2 from the water. When acid is added to a closed system, CO2 has no chance to be released, and the agitation of the water within the system causes bicarbonate to reform.

[0003] Existing water and fertilizer irrigation systems mostly involve adding various fertilizers to the water source to adjust the acidity or alkalinity. However, this method leads to an increase in the amount of fertilizer needed, resulting in waste. Furthermore, it cannot automatically adjust the acidity or monitor the pH value in the water and fertilizer, causing problems for irrigation. Utility Model Content

[0004] The purpose of this invention is to provide an agricultural irrigation acidity adjustment device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an agricultural irrigation pH adjustment device, comprising a base, a control box, a fertilizer tank, a pH adjustment tank, and a water pump. The control box, fertilizer tank, pH adjustment tank, and water pump are all mounted on the base. An irrigation water inlet pipe and a pH adjustment water inlet pipe are fixedly connected to the top of the pH adjustment tank. Both the irrigation water inlet pipe and the pH adjustment water inlet pipe are equipped with solenoid valves. A stirring assembly is installed inside the pH adjustment tank. Two spaced-apart detection tubes are fixedly connected to one side of the pH adjustment tank. A pH detection sensor is installed on each detection tube. A pressure gauge is fixedly installed on the top of the pH adjustment tank. An exhaust valve is fixedly installed on the top of the pH adjustment tank to the side of the pressure gauge. A first conduit is fixedly connected between the inlet end of the water pump and the pH adjustment tank. A second conduit is fixedly connected between the outlet end of the water pump and the fertilizer tank.

[0006] In a preferred embodiment, the top of the fertilizer bucket is threaded with a bucket lid.

[0007] In a preferred embodiment, the stirring assembly includes a motor and a stirring rod. The output end of the motor is fixedly connected to the upper end of the stirring rod. The motor is fixedly installed on the top of the acid-adjusting tank, and the stirring rod is rotatably installed inside the acid-adjusting tank.

[0008] In a preferred embodiment, a valve is provided at the end of the detection tube.

[0009] In a preferred embodiment, a first liquid level window is provided on the side wall of the fertilizer tank, and a second liquid level window is provided on the side wall of the acidification tank.

[0010] In a preferred embodiment, the solenoid valve, pH sensor, pressure gauge, vent valve, motor, and water pump are all electrically connected to the control box.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This agricultural irrigation pH adjustment equipment, with its fertilizer tank, pH adjustment tank, and water pump, allows for pH adjustment by controlling the activation of a solenoid valve. Irrigation water and pH adjustment water enter the pH adjustment tank through the irrigation water inlet pipe and pH adjustment water inlet pipe, respectively. The motor then drives the stirring rod to rotate, mixing the water and adjusting its pH value. During irrigation, the water pump delivers the pH-adjusted irrigation water to the fertilizer tank, where it mixes with fertilizer to form a hydrated fertilizer solution for irrigation, thus achieving automatic pH adjustment and saving fertilizer.

[0013] This agricultural irrigation pH adjustment equipment uses detection tubes and pH sensors. Water from the pH adjustment tank enters two detection tubes, and the pH sensor detects the pH value of the two tubes, ensuring that the pH value remains consistent at different water levels in the pH adjustment tank, thereby automatically monitoring the pH value of the water and fertilizer.

Solenoid valves 43 are installed on both the irrigation water inlet pipe 41 and the pH adjustment water inlet pipe 42. A stirring assembly 44 is installed inside the pH adjustment tank 4. The stirring assembly 44 includes a motor 441 and a stirring rod 442. The output end of the motor 441 is fixedly connected to the upper end of the stirring rod 442. The stirring rod 442 is rotatably installed inside the acid-adjusting tank 4 and the inlet end of the water pump 5 is fixedly connected to the acid-adjusting tank 4 via a first conduit 51. The outlet end of the water pump 5 is fixedly connected to the fertilizer tank 3 via a second conduit 52. With the arrangement of the fertilizer tank 3, the acid-adjusting tank 4, and the water pump 5, the solenoid valve 43 can be activated during acid adjustment. Irrigation water and acid-adjusting water enter the acid-adjusting tank 4 through the irrigation water inlet pipe 41 and the acid-adjusting water inlet pipe 42, respectively. The motor 441 is started to drive the stirring rod 442 to rotate, so that the stirring rod 442 stirs and mixes the water, thereby adjusting the pH value of the irrigation water. During irrigation, the water pump 5 can be started to deliver the pH-adjusted irrigation water to the fertilizer tank 3, where it is mixed with fertilizer to form a hydrated fertilizer for irrigation, thereby achieving automatic acid adjustment and saving fertilizer.

A valve 451 is set at the end of the detection tube 45. Through the detection tube 45 and the pH detection sensor 46, water in the acidification tank 4 will enter the two detection tubes 45. The pH detection sensor 46 can detect the pH value of the two detection tubes 45 to ensure that the pH value of different water levels in the acidification tank 4 is consistent, thereby automatically monitoring the pH value in the water fertilizer.

Irrigation water and acid-adjusting water enter the acid-adjusting tank 4 through the irrigation water inlet pipe 41 and the acid-adjusting water inlet pipe 42, respectively. The motor 441 is started, driving the stirring rod 442 to rotate, causing the stirring rod 442 to stir and mix the water, thereby adjusting the pH value of the irrigation water. The water in the acid-adjusting tank 4 enters two detection tubes 45. The pH value of the two detection tubes 45 can be detected by the pH detection sensor 46 to ensure that the pH value of different water levels in the acid-adjusting tank 4 remains consistent, thus automatically monitoring the pH value of the slurry and fertilizer.
