Technical Field

[0001] The utility model relates to the field of pesticide spraying, in particular to a pesticide spraying device for an aircraft. Background Art

[0002] A pesticide spraying aircraft is a device installed on an aircraft to achieve precise pesticide spraying through aerial operations. Due to the high moving speed of the aircraft, several mu of farmland can be sprayed per minute, and the operation area of a large plant protection aircraft can reach hundreds of mu per hour, far exceeding the efficiency of manual or ground machinery and being adaptable to various terrains. At the same time, when spraying pesticides, there is no need to enter the pesticide spraying area, avoiding direct contact with pesticides and reducing the risk of personnel poisoning.

[0003] In the prior art, a pesticide spraying aircraft usually includes an aircraft and a pesticide spraying device without a bird repelling device. When the pesticide spraying aircraft sprays pesticides, the birds landing in the crops will not fly away in time, which may cause the birds to come into contact with the pesticides and cause harm to the birds.

[0004] Therefore, the present application provides a pesticide spraying device for an aircraft to meet the requirements. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a pesticide spraying device for an aircraft to solve the problem that when the existing pesticide spraying aircraft sprays pesticides, it cannot effectively repel birds, resulting in the contact between the sprayed pesticides and the birds and causing harm to the birds.

[0006] To solve the above-mentioned problems, the utility model is realized through the following technical solutions.

[0040] The following illustrates the implementation manners of the present utility model through specific specific examples. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model.

[0041] Refer to Figures 1 - 8 , a pesticide spraying device for an aircraft, comprising:

[0042] Unmanned aerial vehicle 10;

[0043] The bottom of the unmanned aerial vehicle 10 is fixedly connected with a spraying device 20;

[0044] A reflection mechanism, comprising an outer ring 30 arranged on the top of the unmanned aerial vehicle 10, and a reflective sticker 301 is attached to the outer side of the outer ring 30. The reflection mechanism is used to reflect sunlight downward to drive away birds in the crops;

[0045] The reflection mechanism further includes an inner ring 31. The inner ring 31 includes a plurality of equally spaced wind blades 311 fixed to the outside. The inner ring 31 includes closed surfaces 312 provided at both the top and the bottom. The closed surfaces 312 are used to seal the top and the bottom of the inner ring 31.

[0046] Furthermore, as Figure 6 shown, the inside of the inner ring 31 is made airtight to form a continuous mechanical closed loop. When the wind blades 311 are impacted by the airflow to generate a rotational torque, the inner ring 31 can evenly distribute the load to the entire ring body, avoiding deformation or fracture of the inner ring 31 caused by local stress concentration. At the same time, the closed inner ring 31 can form an annular airflow channel with the outer ring 30 to guide the airflow to flow orderly through the wind blades 311, reducing airflow leakage and turbulence.

[0047] Both of the two closed surfaces 312 are fixedly connected with rotating shafts 32 extending downward. The bottom of the rotating shaft 32 is rotatably connected with a rotating member 33. One end of the rotating member 33 away from the rotating shaft 32 is fixedly connected with a connecting end 34.

[0048] The outer ring 30 includes a connecting rod 302 fixedly connected to the bottom. One end of the connecting rod 302 away from the outer ring 30 is fixedly connected to the bottom of the rotating shaft 32.

[0049] Furthermore, as Figure 6 and Figure 7 shown, after the inner ring 31 rotates, it can drive the outer ring 30 to rotate through the rotating shaft 32 and the connecting rod 302.

[0050] The outer ring 30 is inclined outward from the bottom to the top.

[0051] Furthermore, as Figures 1 to 6 shown, the sunlight reflected by the reflective sticker 301 irradiates the crops below to drive away the birds in the crops.

[0052] The height of the inner ring 31 is greater than that of the outer ring 30, and the middle parts of the inner ring 31 and the outer ring 30 are at the same height.

[0053] Furthermore, as Figure 5 and Figure 6 shown, the inner ring 31 can be in direct contact with the airflow at any time under the movement of the drone 10 and thus rotate.

[0054] The wind blades 311 have an inclination angle of 15° - 20° with the plane of the inner ring 31.

[0055] Furthermore, as shown in the figure, while the rotational torque generated by the contact between the inner ring 31 and the airflow is relatively large, the axial resistance is avoided from being too large to affect the movement of the drone 10.

[0056] The reflection mechanism further includes:

[0057] An empty slot 341 is opened inside the connection end 34;

[0058] A metal sheet 35 is fixed to the bottom of the empty slot 341;

[0059] The outer ring 30 and the inner ring 31 are made of the same kind of carbon fiber material.

[0060] Furthermore, while ensuring the strength of the outer ring 30 and the inner ring 31, the mass of the outer ring 30 and the inner ring 31 is reduced to avoid affecting the operation of the drone 10.

[0061] The structure of the drone 10 includes:

[0062] A card slot 11 is opened at the top of the drone 10 for accommodating the connection end 34;

[0063] A magnetic sheet 12 is fixedly connected to the bottom of the card slot 11 for magnetically connecting the metal sheet 35.

[0064] A propeller hub 13 is fixedly connected to several arms extending outward from the drone 10 to provide power for the drone 10.

[0065] Furthermore, as Figure 2 , Figure 7 and 8 shown, the connection end 34 enters the card slot 11 to fix the reflection mechanism to the top of the drone 10.

[0066] The spraying device 20 includes:

[0067] A nozzle 21 is fixed to the bottom of the corresponding propeller hub 13 for spraying pesticides downward.

[0068] Working process and principle: When the drone 10 moves, the wind blades 311 capture the airflow, causing the inner ring 31 to rotate, and then driving the coaxial outer ring 30 to rotate, thereby generating a downward and continuously flashing light and shadow effect. Utilizing the characteristics that birds are visually sensitive and have a strong fear of novelty, the birds in the crops below are driven away to avoid the sprayed pesticides from contacting the birds in the crops and causing harm to the birds.

[0069] Accordingly, while the present utility model has been described herein with reference to its specific embodiments, modifications, various changes and substitutions are also within the above disclosure, and it should be understood that in some cases, some features of the present utility model will be employed without corresponding use of other features, without departing from the scope and spirit of the proposed utility model. Therefore, many modifications may be made to adapt a particular environment or material to the essential scope and spirit of the present utility model.
