[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-5As shown, according to the quantitative liquid fertilizer delivery device of the embodiment of the utility model, the intelligent fertilization and watering component 3 includes a probe transmission frame 301, the probe transmission frame 301 is installed on both sides of the liquid fertilizer delivery mounting frame 1, a threaded rod 315 is movably installed inside the probe transmission frame 301, one end of the threaded rod 315 is connected to a transmission motor 313, the outer thread of the threaded rod 315 is matched with a moving frame 311, one side of the moving frame 311 is connected to an electric push rod 312, one end of the electric push rod 312 is connected to a sensor mounting frame 316, a soil pH sensor 302 and a soil moisture sensor 303 are respectively installed inside the sensor mounting frame 316, a PLC controller 304 is provided on one side of the liquid fertilizer delivery mounting frame 1, and the PLC controller 304 is A liquid delivery pump 305 is provided on the side, the PLC controller 304 and the liquid delivery pump 305 are respectively connected to the liquid fertilizer delivery mounting frame 1, the input end of the liquid delivery pump 305 is connected to a three-way pipe 306, one side of the three-way pipe 306 is connected to a water adding pipe 310, a water adding valve 307 is installed inside the water adding pipe 310, the output end of the liquid delivery pump 305 is connected to a liquid outlet pipe 308, one end of the liquid outlet pipe 308 is connected to a drip irrigation belt 309, a flow regulating valve 314 is installed inside the drip irrigation belt 309, the soil pH sensor 302, the soil moisture sensor 303, the liquid delivery pump 305, the water adding valve 307, the transmission motor 313, the electric push rod 312, and the flow regulating valve 314 are respectively electrically connected to the PLC controller 304.

[0028] Through the above technical solution, by setting up a transmission motor 313, the transmission motor 313 can drive the threaded rod 315 to rotate in the probe transmission frame 301, and when the threaded rod 315 rotates, it can drive the moving frame 311 to move, and the moving frame 311 can drive the sensor mounting frame 316 to move through the electric push rod 312, and then the electric push rod 312 drives the sensor mounting frame 316 to descend, so that the soil pH sensor 302 and the soil moisture sensor 303 are buried in the planting soil. When the soil pH sensor 302 detects that the pH of the planting soil does not meet the requirements, the soil pH sensor 302 controls the liquid delivery pump 305, the organic fertilizer valve 203 or the ammonium sulfate nitrogen fertilizer valve 204 through the PLC controller 304 to start a certain timer. time, so that the soil pH sensor 302 inputs a certain amount of fertilizer liquid into the liquid outlet pipe 308, and the liquid outlet pipe 308 irrigates the fertilizer liquid through the drip irrigation belt 309. When the soil moisture sensor 303 detects that the moisture of the planting soil is low, the soil moisture sensor 303 orders the water adding valve 307 to open for a certain period of time through the PLC controller 304, and the organic fertilizer valve 203 and the ammonium sulfate nitrogen fertilizer valve 204 are closed. At this time, the planting soil can be humidified by the liquid delivery pump 305, the liquid outlet pipe 308 and the drip irrigation belt 309. The soil pH sensor 302 and the soil moisture sensor 303 can be moved to different positions for detection, and then the PLC controller 304 orders the flow regulating valve 314 at the corresponding position to open, so as to achieve the effect of fixed-point fertilization or humidification in different areas.

The organic fertilizer valve 203 and the ammonium sulfate nitrogen-containing fertilizer valve 204 are respectively electrically connected to the PLC controller 304.

[0031] The pH value of the soil directly affects the plant's ability to absorb nutrients. Generally speaking, soil with a pH value between 6.0 and 7.5 is more fertile, while soil with a pH value that is too high or too low is not conducive to plant growth. If the soil is too acidic, with a pH value below 6.0, organic fertilizers can increase the pH value of the soil and increase the fertility of the soil. If the soil is too alkaline, with a pH value above 7.5, apply ammonium sulfate: ammonium sulfate can lower the pH value of the soil. Generally speaking, 1-2 kg of ammonium sulfate is required for every 100 square meters of land.

[0032] Through the above technical solution, when the soil pH sensor 302 detects that the pH value of the planting soil is lower than 6.0, the soil pH sensor 302 controls the organic fertilizer valve 203 to open through the PLC controller 304; when the soil pH sensor 302 detects that the pH value of the planting soil is lower than 7.5, the soil pH sensor 302 controls the ammonium sulfate nitrogen-containing fertilizer valve 204 to open through the PLC controller 304.

A driving motor 402 is connected to one end of the rotating rod 401, and a stirring rod 403 is connected to the periphery of the stirring rotating rod 401. The driving motor 402 is electrically connected to the PLC controller 304, and the model of the PLC controller 304 is S7-200.

[0034] Through the above technical solution, by setting the driving motor 402, the driving motor 402 can drive the rotating rod 401 to rotate in the organic fertilizer tank 201 and the ammonium sulfate nitrogen-containing fertilizer tank 202, thereby achieving the effect of stirring the fertilizer.

[0036] By setting up the probe transmission frame 301, it is convenient to hang the soil pH sensor 302 and the soil moisture sensor 303. When in use, the soil pH sensor 302 and the soil moisture sensor 303 are placed in the planting soil. When the soil pH sensor 302 detects that the pH of the planting soil does not meet the requirements, the soil pH sensor 302 controls the liquid delivery pump 305, the organic fertilizer valve 203 or the ammonium sulfate nitrogen fertilizer valve 204 through the PLC controller 304 to start a certain time, so that the soil pH sensor 302 inputs a certain amount of fertilizer liquid into the liquid outlet pipe 308, and the liquid outlet pipe 308 irrigates the fertilizer liquid through the drip irrigation belt 309. When the soil moisture sensor 303 detects that the moisture of the planting soil is low, the soil moisture sensor 303 controls the water adding valve through the PLC controller 304. 307 is opened for a certain period of time, and the organic fertilizer valve 203 and the ammonium sulfate nitrogen-containing fertilizer valve 204 are closed. At this time, the planting soil can be humidified by the liquid delivery pump 305, the liquid outlet pipe 308 and the drip irrigation belt 309; when the soil pH sensor 302 detects that the pH value of the planting soil is lower than 6.0, the soil pH sensor 302 controls the organic fertilizer valve 203 to open through the PLC controller 304, and when the soil pH sensor 302 detects that the pH value of the planting soil is lower than 7.5, the soil pH sensor 302 controls the ammonium sulfate nitrogen-containing fertilizer valve 204 to open through the PLC controller 304; by setting the driving motor 402, the driving motor 402 can drive the rotating rod 401 to rotate in the organic fertilizer tank 201 and the ammonium sulfate nitrogen-containing fertilizer tank 202, thereby achieving the effect of stirring the fertilizer.
