Embodiment 1

[0034] like Figure 1-7 As shown, the present invention provides a kind of unmanned aerial vehicle for forestry spraying, comprise unmanned aerial vehicle body 1, the bottom of unmanned aerial vehicle body 1 is fixedly installed with support leg 2, by being provided with support leg 2, can be used in this device When landing, the device is supported to avoid the problem that the bottom of the storage box 3 is in contact with the ground. The middle part of the drone body 1 is detachably connected to the storage box 3, and the bottom of the support leg 2 is provided with a landing buffer mechanism 4. The storage box The inner cavity of the body 3 is provided with an anti-sedimentation mechanism 5, the bottom of the storage box 3 is provided with an extension spraying mechanism 6, the bottom of the storage box 3 is fixedly installed with a pump body 31, and the landing buffer mechanism 4 includes a laser distance measuring sensor 41. And the fixed plate 42, the fixed plate 42 is ...

Embodiment 2

[0037] like Figure 1-7 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, a buffer airbag 44 is fixedly installed between two silica gel pads 43, and a pressure valve 45 is fixedly connected to the right side of the buffer airbag 44, The bottom of the silicone pad 43 is fixedly connected with a rubber bottom rod 46 , and the outer wall of the rubber bottom rod 46 is fixedly connected with a protective stripe 47 .

[0038] In this embodiment, when the device falls to the ground, the gravity of the device itself will squeeze the buffer air bag 44, causing the buffer air bag 44 to discharge gas through the pressure valve 45 to realize the function of buffering. The softness at the bottom of the device protects the buffer airbag 44, increases the wear resistance of the bottom of the device by providing a rubber bottom rod 46, and increases the friction between the bottom of the device and the ground by providing protective stripe...

Embodiment 3

[0040] like Figure 1-7As shown, on the basis of Embodiment 1, the present invention provides a technical solution: preferably, the connecting pipe 51 is arranged in the inner cavity of the storage box 3, and the bottom of the connecting pipe 51 is fixed to the input end of the pump body 31 Connection, the right side of the absorption pipe 52 is provided with an entry groove 53, through which the entry groove 53 is provided, so that the medicine flows into the absorption pipe 52 from the corner of the storage box 3 inner cavity, preventing the medicine from entering the corner of the storage box 3 inner cavity. The problem of precipitation occurs at the place, the front and back of the main shaft 54 ​​respectively extend to the front and back of the absorption pipe 52 and are fixedly connected with an arc-shaped stirring plate 551, and the side of the arc-shaped stirring plate 551 is provided with a through hole 552, and the arc-shaped stirring plate 551 is away from One end o...

Abstract

The invention discloses an unmanned aerial vehicle for forestry spraying, and relates to the technical field of forestry maintenance, the unmanned aerial vehicle comprises an unmanned aerial vehicle body, supporting legs are fixedly mounted at the bottom of the unmanned aerial vehicle body, a storage box is detachably connected to the middle of the unmanned aerial vehicle body, and landing buffer mechanisms are arranged at the bottoms of the supporting legs; and an anti-precipitation mechanism is arranged in an inner cavity of the storage box body, and a stretching spraying mechanism is arranged at the bottom of the storage box body. The laser distance measuring sensor is used for monitoring the ground clearance, information is fed back to an operator in time, the operator is prompted to decelerate correspondingly, the problem that the landing speed is too high is avoided, impact force borne by the unmanned aerial vehicle body during landing is buffered through cooperation of a silica gel pad, a buffering air bag and a rubber bottom rod, the problem that devices in the unmanned aerial vehicle body are possibly damaged due to vibration due to large impact force during landing is solved, the unmanned aerial vehicle body and the devices installed on the unmanned aerial vehicle body are buffered and protected, and the service life of the unmanned aerial vehicle body is prolonged.

Description

technical field [0001] The invention relates to the technical field of forestry maintenance, in particular to an unmanned aerial vehicle used for forestry spraying. Background technique [0002] UAV is an unmanned aircraft operated by radio remote control equipment and self-contained program control device, or completely or intermittently operated autonomously by on-board computer. In forestry planting, pests and diseases are very troublesome things. Spray pesticides to protect against pests and diseases. Since manual spraying is more troublesome, drones are now used to replace manual spraying of pesticides. There are following problems at prior art: [0003] 1. The existing drones do not have the buffer function when they land, and the impact force when landing is relatively large, which may cause damage to the internal components of the drone due to vibration, which needs to be improved; [0004] 2. Existing drones do not have the function of adjusting the height of spra...
