Description

Technical Field

[0001] The utility model relates to a general aircraft agricultural application technology, in particular to a plant protection aircraft sowing equipment. Background Art

[0002] Plant protection UAV, also known as unmanned aerial vehicle, is an unmanned aircraft used for agricultural and forestry plant protection operations. This type of unmanned aircraft consists of three parts: a flight platform (fixed-wing, helicopter, multi-axis aircraft), a navigation flight control, and a spraying mechanism. It can spray pesticides, seeds, powders, etc. through ground remote control or navigation flight control.

[0003] A Chinese patent document with the authorization publication number CN210503179U discloses a plant protection UAV with a stable flight center of gravity. Conventional UAVs cannot flexibly adjust flight control and flight attitude due to their own structural reasons, cannot adapt to flights in special weather and special operation requirements, and have poor operation results. In the utility model, a suspension rod is provided between the swing arm and the fuselage, and the suspension rod is provided with a protective cover, which includes a connecting part and a frame part; the frame part includes a strut and a ring rod, and a plurality of support rods are longitudinally provided between the ring rods, and two symmetrical folding plates are provided on the support rods. The utility model uses a suspension rod to separate the rotor part of the UAV from the fuselage of the UAV and the operating part (including the box, etc.) for plant protection, so that the overall center of gravity of the UAV is sunk, which greatly improves the flight stability of the UAV during operation, and can also ensure that the UAV can still fly smoothly when sudden situations such as sudden changes in airflow or collision and scraping of the UAV occur.

[0004] However, in the prior art, when the wind speed is high, the sowing box will not sow evenly and the protective cover used is expensive, heavy and has high wind resistance. Utility Model Content

[0005] The utility model aims to provide a plant protection aircraft sowing device, which is used to solve the problems of uneven sowing in the existing sowing box and large weight and wind resistance of the protective cover.

[0006] In order to solve the above problems, the utility model provides a plant protection aircraft sowing equipment, including a sowing box, a mounting hole is provided at the top of the sowing box, a suspension rod is threadedly connected to the mounting hole, a thread is provided at the middle and lower ends of the suspension rod, a fixing bolt is connected to the thread, a connecting ring is provided at the periphery of the fixing bolt, a support rod is fixedly connected to the outer edge of the connecting ring, the number of the support rods is more than two, nylon cloth is provided between the more than two support rods, and a shielding plate is hinged on the side of the sowing box.

[0007] The plant protection aircraft seeding equipment provided by the utility model also has the following technical features:

[0008] Furthermore, a bracket is fixedly connected to the bottom of the seeding box.

[0009] Furthermore, the lower edge of the support rod is flush with the lower edge of the seed box.

[0010] Furthermore, nuts are provided at both ends of the fixing bolt.

[0011] Furthermore, the nylon cloth is bound to the support rod by means of ropes.

[0012] Furthermore, a nameplate is provided on the back of the seeding box.

[0013] The utility model has the following beneficial effects: by hingedly connecting a shielding plate to the side of the seeding box, when sowing at a high wind speed, the shielding plate can be adjusted in advance so that when the seeds are led out of the seeding box, they are affected by the shielding plate and their falling trajectory is changed, thereby ensuring that the seeds are evenly scattered on the land; the periphery of the seeding box is protected by support rods and nylon cloth, which has the advantages of low cost, light weight and small wind resistance.
