Description

Technical Field

[0001] The present invention relates to the technical field of integrated water and fertilizer machines, and in particular to a water and fertilizer integrated farmland sprinkler irrigation device based on new energy. Background Art

[0002] my country is a major crop producer and also a major consumer of water and fertilizer. However, the effective utilization rate of both is far from satisfactory. Integrated water and fertilizer is a modern, advanced agricultural technology that combines drip irrigation with fertilization. It achieves the integrated utilization and management of water and fertilizer, ensuring that water and fertilizer are optimally combined in the soil for crop absorption and utilization. The main application modes of integrated water and fertilizer technology in my country currently include sprinkler irrigation, drip irrigation, and micro-sprinkler irrigation.

[0003] Existing sprinkler irrigation systems all need to be pressurized. Sprinkler irrigation is greatly affected by wind, resulting in air losses and a greater impact on air humidity. It has the disadvantages of sufficient moistening of the surface soil and insufficient moistening of the deep soil. Drip irrigation has high requirements for water quality, large initial investment, and filters must be installed and require regular cleaning and maintenance. The disadvantage of micro-sprinkler irrigation is that it has high requirements for the water quality of the irrigation water source, and the irrigation water must be filtered. The nozzles of micro-sprinkler irrigation in the field are easily blocked by weeds, crop stems and other debris, and the spraying quality and uniformity are greatly affected by the wind.

[0004] Based on this, this application is filed. Summary of the Invention

[0034] like Figures 1 to 2 As shown, a water-fertilizer integrated farmland sprinkler irrigation device based on new energy includes a frame 3, a fertilizer mixing barrel 10, a solar panel 7, a feeding device 6, a stirring device 8 and a control module 15. The bottom of the frame 3 is provided with a universal wheel 13 and a bottom plate 12. The fertilizer mixing barrel 10, a water pump 1 and a controller 17 are installed on the bottom plate 12. The top of the frame 3 is provided with an upper cover plate 4 to prevent the sprayed water from splashing onto the control template 15, the battery 16 and the controller 17. The fertilizer mixing barrel 10 is provided with a water inlet 9, a filter 18 is installed at the bottom outlet, and is connected to the water pump 1 through a water pipe 2 11. The water pump 1 is then connected to a rotary nozzle 5 through a water pipe 1 2. The water pump 1 extracts the mixed fertilizer liquid in the fertilizer mixing barrel 10 and sprays it through the rotary nozzle 5. The rotary nozzle 5 can achieve 0°-360° adjustable reciprocating rotation. The rotary nozzle 5 is installed on the upper cover plate 4, and the upper cover plate 4 is fixed to the frame 3 by a nut;

[0035] The solar panel 7 is mounted on the frame 3 via a plurality of self-locking hinges 14. The self-locking hinges 14 can be fixed at 0° and 90°. One side of the self-locking hinge 14 fixes the solar panel 7, and the other side fixes the frame 3. When in use, the self-locking hinge 14 is adjusted to a 90° self-locking angle, and when not in use, it is adjusted to a 0° self-locking angle. The solar panel 7 is connected to the controller 17. The controller 17 controls the output voltage of the solar panel 7 to be stable at 12V, and transmits the electricity to the battery 16. The battery 16 is connected to the control module 15 and supplies power to the control module 15.

[0036] Among them, the control module 15 is connected to the stepper motor 1 62 and the stepper motor 2 81. The control module 15 controls the feeding speed and feeding amount by adjusting the speed of the stepper motor 1 62 and thus adjusting the speed of rotation of the screw 64. It can also adjust the stirring speed by adjusting the speed of the stepper motor 2 81 to adjust the concentration of the mixed fertilizer liquid in the mixing barrel 10.

[0037] like Figures 3 and 4 As shown, the feeding device 6 includes a funnel 61, a stepper motor 62, a coupling 63 and a screw 64. The stepper motor 62 is fixed to the frame 3. The funnel 61 is a 45° tapered cone to facilitate the entry of fertilizer. The stepper motor 62 is connected to the screw 64 through the coupling 63 and rotates synchronously. The screw 64 drives the falling fertilizer to feed forward.

[0038] The stirring device 8 includes a stepper motor 81, a coupling 82, a stirring rod 83 and a stirring blade 84. The stepper motor 81 is fixed on the frame 3. The stepper motor 81 is connected to the stirring rod 83 through the coupling 82 and rotates synchronously. The control module 15 is connected to the stepper motor 62 and the stepper motor 81. The control module 15 controls the speed of the stepper motor 62 and the stepper motor 81 respectively by writing program codes, controls the speed of the stepper motor 62 to adjust the feeding speed and feeding amount, and controls the speed of the stepper motor 82 to adjust the stirring speed to control the concentration.

[0039] Working principle: During the use of the water-fertilizer integrated machine, fertilizer is put into the hopper 61 of the feeding device 6, and the control module 15 controls the stepper motor 1 62 to rotate, and drives the screw 64 to rotate through the coupling 1 63 to push the fertilizer into the feeding outlet 65. At the same time, water is also injected into the water inlet 9 of the fertilizer mixing barrel 10. The control module 15 controls the stepper motor 2 81 to rotate, and drives the stirring rod 83 to rotate and stir the mixed fertilizer liquid in the fertilizer mixing barrel 10 through the coupling 2 82. Feeding, stirring and water injection are carried out simultaneously to reduce the time of fertilizer mixing. A filter 18 is installed at the bottom outlet of the fertilizer mixing barrel 10 to prevent undissolved particles from clogging the rotary nozzle 5. The bottom outlet of the fertilizer mixing barrel 10 is connected to the water pipe 11. The water pump 1 extracts the mixed fertilizer liquid from the rotary nozzle 5 and sprays it. The rotary nozzle 5 is at a certain angle. The reciprocating rotation makes the mixed fertilizer liquid sprayed in an area. The solar panel 7 is installed on the frame 3 through several self-locking hinges 14. The self-locking hinges 14 are adjusted to be 90° self-locking so that the solar panel 7 receives light. The solar panel 7 is connected to the control board 17. The control board 17 is used to adjust the output voltage of the solar panel 7. The control board 17 is connected to the battery 16 for powering it. The battery 16 and the control module 15 are connected for powering it. The control module 15 is connected to the stepper motor 62 and the stepper motor 81. The program of the control template 15 is written to control the speed of the stepper motor 62 and the stepper motor 81 respectively. It can operate in the field without power supply and continuously supply solid fertilizer for a long time without mixing it one by one, thereby reducing the waste of water resources and increasing the utilization of fertilizer.
