The technical solution adopted is as follows: it includes a mobile platform 1, a fixing plate 2, a water storage tank 4, a stirring assembly 5 and a conveying assembly 6. Universal wheels 12 are respectively fixedly installed at the four corners of the bottom of the mobile platform 1. Push handles 11 are respectively arranged at the top parts on the left and right sides of the mobile platform 1. Through the design of the push handles 11 and the universal wheels 12, it is convenient to move the device. The mobile platform 1 is of a U-shaped structure. A fixing plate 2 is fixedly installed at the inner top of the mobile platform 1. And a water injection pipe 7 arranged at the center of the top of the fixing plate 2 is internally communicated with the inside of the water storage tank 4 arranged at the center of the bottom of the fixing plate 2. A drain pipe 8 is arranged at the bottom of the water storage tank 4. An electric valve 9 is arranged at the top of the drain pipe 8. A stirring assembly 5 is arranged at the inner top of the water storage tank 4. The stirring assembly 5 is composed of a fixing frame 51, an impeller 52, a rotating shaft 53 and a stirring rod 54. The fixing frame 51 is arranged in the middle of the inner side of the water storage tank 4. The fixing frame 51 is of a "cross" structure. The center of the fixing frame 51 is rotatably installed with a rotating shaft 53 through a tapered roller bearing. An impeller 52 is arranged at the top of the rotating shaft 53. And the impeller 52 is located directly below the liquid discharge end of the water injection pipe 7. Stirring rods 54 are arranged at equal intervals in a circumferential array at the bottom outside the rotating shaft 53. Water is injected into the inside of the water storage tank 4 through the water injection pipe 7. The water injection pipe 7 is connected to the center of the top of the fixing plate 2 to ensure that water can smoothly enter the water storage tank 4. As the water is continuously injected, at this time, the injected water flow drives the impeller 52 to rotate. Through the rotation of the impeller 52 and the stirring rod 54, the liquid medicine and water are fully mixed evenly to form a mixed liquid suitable for irrigation. Then, the electric valve 9 is opened to make the mixed liquid flow out through the drain pipe 8 to carry out the irrigation and fertilization work for crops. A liquid level sensor 10 is fixedly installed at the left end of the top of the fixing frame 51. The rear top of the water storage tank 4 is communicated with a conveying assembly 6 arranged at the rear end of the mobile platform 1. The conveying assembly 6 is composed of a liquid medicine cylinder 61, a cylinder cover 63, an electric telescopic rod 64, a connecting pipe 65, a flow meter 66 and a piston plate 67. The liquid medicine cylinder 61 is arranged at the left rear end of the fixing plate 2. A cylinder cover 63 is threadedly installed on the outer top of the liquid medicine cylinder 61. A blocking plug is arranged at the inner top of the cylinder cover 63. And the outer side of the blocking plug is in movable contact with the inner wall of the liquid medicine cylinder 61. An electric telescopic rod 64 is arranged directly below the liquid medicine cylinder 61. The electric telescopic rod 64 is fixedly installed at the inner bottom of the mobile platform 1. The telescopic end of the electric telescopic rod 64 passes through a sliding hole arranged at the center of the bottom of the liquid medicine cylinder 61 and is fixedly connected to a piston plate 67 slidably installed at the inner bottom of the liquid medicine cylinder 61. A connecting pipe 65 is arranged on the outer top of the liquid medicine cylinder 61. And the other end of the connecting pipe 65 is communicated with the inside of the water storage tank 4. A flow meter 66 is arranged in the middle of the connecting pipe 65. By the telescopic end of the electric telescopic rod 64 extending upward and driving the piston plate 67 to slide inside the liquid medicine cylinder 61, as the piston plate 67 continuously rises, the liquid medicine in the liquid medicine cylinder 61 is squeezed and flows into the water storage tank 4 through the connecting pipe 65. During the process of the liquid medicine flowing into the water storage tank 4 through the connecting pipe 65, the flow meter 66 arranged on the connecting pipe 65 plays a key role.The flowmeter 66 can detect and control the flow rate of the liquid medicine flowing through the connecting pipe 65, ensuring that an appropriate amount of liquid medicine is added to the water storage tank 4 according to the preset mixing ratio. An observation window 62 is provided in the middle of the front side of the liquid medicine cylinder 61. Through the design of the observation window 62, it is convenient to observe the remaining amount of the liquid medicine, ensuring that the amount of added liquid medicine is accurate. It also includes a controller 3. The controller 3 is fixedly installed on the outside of the extension plate provided at the right end of the front side of the fixed plate 2. The output end of the controller 3 is electrically connected to the input ends of the electric telescopic rod 64 and the electric valve 9. The input end of the controller 3 is electrically connected to the output end of the liquid level sensor 10 and the external power supply. Through the design of the controller 3, the controller 3 can, according to the feedback signal of the liquid level sensor 10, monitor the liquid level situation in the water storage tank 4 in real time, and cooperate to mix the liquid medicine and irrigation water in an accurate proportion. At the same time, when the liquid level reaches the preset value, the controller 3 can automatically close the water injection pipe 7.,

[0019] The working principle of the present utility model: First, when it is necessary to irrigate and fertilize crops, the staff first adds an appropriate amount of liquid medicine into the liquid medicine cylinder 61 through the cylinder cover 63. In order to facilitate observing the remaining amount of the liquid medicine, an observation window 62 is provided on the liquid medicine cylinder 61 to ensure that the amount of added liquid medicine is accurate. Then, according to the growth state of the crops and the required irrigation and fertilization plan, the staff starts the electric telescopic rod 64 through the controller 3. The telescopic end of the electric telescopic rod 64 extends upward and drives the piston plate 67 fixedly connected thereto to slide inside the liquid medicine cylinder 61. As the piston plate 67 continuously rises, the liquid medicine in the liquid medicine cylinder 61 is squeezed and flows through the connecting pipe 65 into the water storage tank 4. During the process of the liquid medicine flowing through the connecting pipe 65 into the water storage tank 4, the flowmeter 66 provided on the connecting pipe 65 plays a key role. The flowmeter 66 can detect and control the flow rate of the liquid medicine flowing through the connecting pipe 65, ensuring that an appropriate amount of liquid medicine is added to the water storage tank 4 according to the preset mixing ratio. Finally, water is injected into the inside of the water storage tank 4 through the water injection pipe 7. The water injection pipe 7 is communicated with the center of the top of the fixed plate 2 to ensure that water can smoothly enter the water storage tank 4. As the water is continuously injected, at this time, the injected water flow drives the impeller 52 to rotate. Through the rotation of the impeller 52 and the stirring rod 54, the liquid medicine and water are fully mixed evenly to form a mixed liquid suitable for irrigation. The liquid level sensor 10 can monitor the liquid level situation in the water storage tank 4 in real time and cooperate to mix the liquid medicine and irrigation water in an accurate proportion. The staff can open the electric valve 9 through the controller 3 to make the mixed liquid flow out through the drain pipe 8 for the irrigation and fertilization work of the crops. During the whole process, the controller 3, according to the feedback signal of the liquid level sensor 10, monitors the liquid level situation in the water storage tank 4 in real time to ensure the smooth progress of the irrigation and fertilization work.,
