Description

Technical Field

[0001] The present invention relates to the technical field of agricultural fertilization, and particularly to an adjustable fertilization device for agricultural drones. Background Art

[0002] The advantages of drone fertilization mainly include improving efficiency, saving costs, uniform fertilization, environmental protection, and promoting crop growth. Improving efficiency and uniform fertilization: Drones can quickly and evenly fertilize vast farmlands without leaving any dead spots, which is more efficient than traditional manual or mechanical methods. For example, a drone can complete the fertilization of a large area of farmland in one day, while traditional methods require more time and manpower. Saving costs: By reducing the required human and material resources, drone fertilization significantly reduces operating costs. In addition, precise fertilization technology reduces the waste of chemical fertilizers, further saving the costs of agricultural production. Environmental protection and reducing environmental pollution: The use of drones reduces the overuse of pesticides and chemical fertilizers, thus contributing to environmental protection and reducing pollution to the soil and water sources. At the same time, by precisely controlling the application amount, the utilization rate of chemical fertilizers is increased, reducing the waste of resources. Promoting crop growth: Uniform and appropriate fertilization helps crops grow healthily, increasing the number of grains per ear and improving the yield. In addition, drone fertilization can also prevent the impact of adverse conditions such as low temperature on crops, improving the overall yield and quality of crops. Easy operation: The operation of drones is relatively simple and easy for farmers to master, which helps to quickly promote and apply new technologies.

[0003] In the prior art, fixed spraying radius operations are usually carried out. However, in the prior art, the spraying radius cannot be adaptively adjusted according to the actual situation. Therefore, the spraying efficiency is low, and there is a large room for improvement in the prior art. Summary of the Invention

[0025] The feeding cylinder mechanism 4 includes a feeding cylinder 401 fixed inside the main box body 1, and a plurality of first feeding holes 402 are provided on the side of the feeding cylinder 401. The rotating ring shell mechanism 5 includes a rotating shell 501 rotatably connected to the main box body 1, the rotating shell 501 is fixedly connected to a rotating cylinder 502, the rotating cylinder 502 is rotatably connected to the feeding cylinder 401, a plurality of second feeding holes 503 are provided on the side of the rotating cylinder 502, and the rotating side ring 6 is rotatably connected to the rotating cylinder 502. The rotating fan blade mechanism 7 includes a rotating fan blade shaft 701 rotatably connected to the rotating shell 501, the rotating fan blade shaft 701 is fixedly connected to a rotating fan blade 702, the rotating fan blade shaft 701 is fixedly connected to a rotating rod 703, the rotating rod 703 is fixedly connected to a first ball seat 704, a first ball 705 is provided inside the first ball seat 704, the rotating side ring 6 is fixedly connected to a second ball seat 706, a second ball 707 is provided inside the second ball seat 706, and an adjusting rod 708 is fixedly connected between the first ball 705 and the second ball 707. The deflection adjusting mechanism 8 includes a displacement seat 801 fixed to the side of the rotating shell 501, the displacement seat 801 is rotatably connected to a linear motor 802, one end of the linear motor 802 away from the displacement seat 801 is rotatably connected to a deflection shaft 803, the deflection shaft 803 is rotatably connected to a deflection rod 804, and the deflection rod 804 is fixedly connected to the rotating side ring 6. The lifting feeding mechanism 9 includes a fixed feeding cylinder 901 fixed to the inner top of the feeding cylinder 401, a plurality of third feeding holes are provided on the side of the fixed feeding cylinder 901, the fixed feeding cylinder 901 is slidably connected to a feeding pipe 902, the feeding pipe 902 is fixedly connected to a pressurized feeding head 903, two telescopic rods 904 are fixedly connected between the pressurized feeding head 903 and the rotating shell 501, a wave-shaped groove 905 is provided on the side of the fixed feeding cylinder 901, the wave-shaped groove 905 is closed, the pressurized feeding head 903 is fixedly connected to a fixed rod 906, the fixed rod 906 is fixedly connected to a clamping rod 907, the clamping rod 907 is located in the wave-shaped groove 905, and the clamping rod 907 is slidably connected to the fixed feeding cylinder 901.

[0026] Specifically, when the linear motor 802 is turned on, the linear motor 802 can drive the rotating side ring 6 to deflect around the rotating shell 501. At this time, the relative positions of the first ball 705 and the second ball 707 can be changed. Driven by the adjusting rod 708, the rotating rod 703 can be driven to deflect, and then the rotating fan blade shaft 701 can be driven to rotate. The rotation of the rotating fan blade shaft 701 will drive the rotating fan blade 702 to deflect.

[0027] In addition, after the drone takes off, the propeller blades will blow downward at this time, generating an air flow, which drives the rotating fan blade 702 to rotate, and then drives the rotating housing 501 to rotate, thereby driving the rotating cylinder 502 to rotate. At this time, the second feeding hole 503 and the first feeding hole 402 intermittently coincide, and the fertilizer enters the third feeding hole of the fixed feeding cylinder 901 through the first feeding hole 402 and the second feeding hole 503. The rotation of the rotating housing 501 drives the telescopic rod 904 to rotate, and the rotation of the telescopic rod 904 drives the pressurized feeding head 903 to rotate, further causing the fixed rod 906 and the clamping rod 907 to rotate. Since the clamping rod 907 is stuck in the wave groove 905, as the fixed feeding cylinder 901 and the feeding pipe 902 rotate, the feeding pipe 902 will also telescopically move relative to the fixed feeding cylinder 901. When the feeding pipe 902 moves to the uppermost position, the fertilizer passes through the fixed feeding cylinder 901. The side of the feeding pipe 902 is provided with a feeding hole, and the fertilizer enters the feeding pipe 902 through the third feeding hole and the feeding hole. The fertilizer will enter the pressurized feeding head 903 through the feeding pipe 902.

[0028] The deflection fertilization mechanism 10 includes a mounting frame 1001 fixed to the side of the pressurized feeding head 903. The mounting frame 1001 is fixedly connected to a fixed pipe 1002. The fixed pipe 1002 is rotatably connected to a deflection nozzle 1003. The tail of the deflection nozzle 1003 is connected to the fixed pipe 1002. The interior of the mounting frame 1001 is a cavity structure. The cavity inside the mounting frame 1001 communicates with the pressurized feeding head 903, and the cavity of the mounting frame 1001 communicates with the fixed pipe 1002.

[0029] Specifically, the fertilizer entering the pressurized feeding head 903 will enter the fixed pipe 1002 through the mounting frame 1001 and is finally sprayed out through the deflection nozzle 1003, thereby realizing fertilization. In addition, when the rotation speed of the pressurized feeding head 903 is different, at this time, under the action of centripetal force, the angle at which the deflection nozzle 1003 rotates around the fixed pipe 1002 is also different, so the fertilization radius can be controlled.

[0030] Example 2, continue to refer to Figures 1 - 3 , in the embodiment of the present invention, the main box body 1 is cylindrical, and the main box body 1 is provided with a feed and discharge port 11.

[0031] Specifically, the fertilizer can be quickly put into the main box body 1 through the feed and discharge port 11.

[0032] In the implementation process of the present invention, first, fertilizers are filled into the main box body 1, and then the sealing cover plate 3 is closed on the main box body 1 to seal the main box body 1. One end of the connecting rope is fixed on the hanging ring 2, and then the other end of the connecting rope is fixed on the unmanned aerial vehicle (UAV). At this time, as the UAV takes off, the rotors of the UAV will blow downward, thus blowing the rotating fan blade mechanism 7. The rotating fan blade mechanism 7 will drive the rotating ring shell mechanism 5 to rotate, and further drive the lifting feeding mechanism 9 to rotate. At this time, the fertilizers in the main box body 1 will pass through the feeding tube mechanism 4, and then through the rotating ring shell mechanism 5 to make the fertilizers enter the lifting feeding mechanism 9, and finally the fertilizers are discharged through the deflection fertilizing mechanism 10. Turning on the deflection adjustment mechanism 8 can adjust the relative positions of the rotating ring shell mechanism 5 and the rotating side ring 6. At this time, the state of the rotating fan blade mechanism 7 will change, resulting in a change in the rotation speed of the rotating fan blade mechanism 7, and further adjusting the rotation speed of the rotating ring shell mechanism 5. At this time, both the fertilizing radius and the fertilizing amount will change.

[0033] By setting the deflection adjustment mechanism 8, the present invention can adjust the relative positions of the rotating ring shell mechanism 5 and the rotating side ring 6, and then adjust the state of the rotating fan blade mechanism 7 to achieve the adjustment of the rotation speed of the rotating fan blade mechanism 7. The rotating fan blade mechanism 7 can drive the rotating ring shell mechanism 5 to rotate, thereby adjusting the fertilizing radius of the deflection fertilizing mechanism 10 and improving the efficiency of road detection and sampling.
