Based on the described embodiments of 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] Reference Figure 1 The utility model embodiment proposes an automatic fertilization drip irrigation device, including a support frame 1, a first motor 2 is installed in the support frame 1, a stirring barrel 3 is installed on the support frame 1, the output end of the first motor 2 passes through the bottom of the stirring barrel 3 and extends into the stirring barrel 3, a stirring assembly 4 is arranged in the stirring barrel 3, the stirring assembly 4 includes a stirring column 41 rotatably connected to the stirring barrel 3, the bottom of the stirring column 41 is fixedly connected to the output end of the first motor 2, a plurality of stirring rods 42 are fixedly connected to the stirring column 41, the first motor 2 drives the stirring column 41 to rotate, the stirring column 41 drives the stirring rod 42 to rotate, and then the water and fertilizer in the stirring barrel 3 are stirred, so that the water and the fertilizer are evenly mixed, and the user can intuitively see the water intake inside the stirring barrel 3 from the outside of the stirring barrel 3.

[0028] Reference Figure 1 A feeding assembly 5 is provided on the top of the mixing barrel 3. The feeding assembly 5 includes a plurality of fertilizer barrels 51 fixedly connected to the top of the mixing barrel 3 and a plurality of feed ports 52 opened on the top of the mixing barrel 3. The fertilizer barrels 51 are connected to the mixing barrel 3 through the feed ports 52. A solenoid valve 53 is installed in the feed port 52 to control the opening and closing of the feed port 52. The opening and closing of the feed port 52 are controlled by the solenoid valve 53, so as to control the falling of the fertilizer. The solenoid valve 53 specifically adopts the AIRTAC series of AirTac. When fertilizer needs to be added, the solenoid valve 53 is opened, and when the adding is completed, the solenoid valve 53 is closed. The fertilizer barrel 51 is conical, so that the fertilizer in the fertilizer barrel 51 can fall into the mixing barrel 3 more smoothly when the solenoid valve 53 is opened, and there will be no situation where there is residual fertilizer in the fertilizer barrel 51 and cannot fall.

[0029] Reference Figure 1 One side of the mixing barrel 3 is connected to a water inlet pipe 6, and the other side of the mixing barrel 3 is connected to a water outlet pipe 7. A water pump 8 is installed on the side of the support frame 1 away from the water inlet pipe 6. The input end of the water pump 8 is connected to the water outlet pipe 7, and the output end of the water pump 8 is connected to the drip irrigation pipe.

[0030] Reference Figure 2The automatic fertilization drip irrigation equipment also includes a control module 100, a user terminal 200, a monitoring module 300, and a communication module 400. The control module 100, the user terminal 200, the monitoring module 300, the communication module 400 and the solenoid valve 53 are electrically connected. The monitoring module 300 includes a soil nitrogen, phosphorus and potassium sensor, a soil moisture sensor and a flow sensor. The soil moisture sensor adopts the JXBS-3001-TR model, the flow sensor adopts the Hills S401 / S421 thermal mass flow sensor, and the soil nitrogen, phosphorus and potassium sensor adopts the DF-NPK model of Dongfang Xinhong. The control module 100 adopts the MCS-51 series AT89C52 as the MCU. The soil nitrogen, phosphorus and potassium sensor and the soil moisture sensor are both buried in the ground. The flow sensor is installed at the feed port 52. The soil nitrogen, phosphorus and potassium sensor and the soil moisture sensor both use the RS485 interface for data transmission, which can realize the function of automatic data transmission, which is convenient for users to automatically control them. When in use, the soil nitrogen, phosphorus, potassium sensor and soil moisture sensor buried in the soil can monitor the nitrogen, phosphorus, potassium content and moisture in the soil in real time, and transmit the monitored nitrogen, phosphorus, potassium content to the control module 100, and the control module 100 transmits it to the user end 200 through the communication module 400, so that the user can intuitively understand the nitrogen, phosphorus, potassium content and moisture content in the soil at the user end 200. When fertilizer is lacking, the user can independently judge the type of fertilizer lacking in the soil through the data, and calculate the fertilizer content that should be added to the drip irrigation water during the next drip irrigation by the user, and then the user transmits the amount of fertilizer to be added and the type of fertilizer to the control module 100 in advance and controls it. The solenoid valve 53 at the lower end of the corresponding fertilizer barrel 51 is opened, so that the corresponding lacking fertilizer flows into the mixing barrel 3. At this time, the flow sensor monitors the outflowing liquid in real time. When the amount of fertilizer flowing out reaches the preset standard, the flow sensor transmits a signal to the control module 100, and the control module 100 controls the solenoid valve 53 to close. When the soil nitrogen, phosphorus and potassium sensor and the soil moisture sensor detect that there is insufficient moisture in the soil but there is no lack of fertilizer, the soil moisture sensor transmits a signal to the control module 100, and the control module 100 feeds back to the user end 200. The user can directly drip irrigate the soil without adding fertilizer, which ensures that the user can accurately control the amount of water or water-fertilizer drip irrigation and avoids waste of resources.

[0031] The specific implementation method is as follows: when in use, the soil nitrogen, phosphorus, potassium sensor and soil moisture sensor buried in the soil can monitor the nitrogen, phosphorus, potassium content and moisture in the soil in real time, and transmit the monitored nitrogen, phosphorus, potassium content to the control module 100, and the control module 100 transmits it to the user end 200 through the communication module 400, so that the user can intuitively understand the nitrogen, phosphorus, potassium content and moisture content in the soil at the user end 200. When fertilizer is lacking, the user can independently judge the type of fertilizer lacking in the soil through the data, and calculate the fertilizer content that should be added to the drip irrigation water during the next drip irrigation through the user's independent calculation, and then the user transmits the amount of fertilizer to be added and the type of fertilizer to be added to the control module 100 in advance and controls the solenoid valve 53 at the lower end of the corresponding fertilizer barrel 51 to open, so that the corresponding lacking fertilizer flows into the mixing barrel 3, and at this time the flow sensor is connected to the outflowing liquid Real-time monitoring is performed. When the amount of fertilizer flowing out reaches the preset standard, the flow sensor transmits a signal to the control module 100, and the control module 100 controls the solenoid valve 53 to close. At the same time, the user adds water to the mixing barrel 3 through the water inlet pipe 6 and observes the water intake through the outside of the mixing barrel 3. At the same time, the first motor 2 is started to stir the water and fertilizer. When the water is added to the appropriate liquid level, no more water is added and the water pump 8 is started. The water pump 8 outputs the water-fertilizer mixture in the mixing barrel 3 through the water outlet pipe 7 to drip irrigate the crops. When the soil nitrogen, phosphorus and potassium sensor and the soil moisture sensor detect that there is insufficient moisture in the soil but no shortage of fertilizer, the soil moisture sensor transmits a signal to the control module 100, and the control module 100 feeds back to the user end 200. The user can directly drip irrigate the soil without adding fertilizer, ensuring that the user can accurately control the amount of water or water-fertilizer drip irrigation and avoiding waste of resources.
