Description

Technical Field

[0001] The utility model relates to the technical field of spraying equipment, in particular to a forestry pest control sprayer based on an unmanned aerial vehicle. Background Art

[0002] Pests include various pests that harm plants, harmful animals, pathogenic microorganisms, and parasitic seed plants. They refer to organisms that, under certain conditions, are harmful to human life, production, and even survival. They are organisms whose large numbers can cause serious damage to captive animals and cultivated crops, flowers, and seedlings. Pests are a major factor that endangers the development of forestry. Therefore, forestry workers need to spray trees regularly to prevent pests.

[0003] In the prior art, application number CN202121402718.5 provides an unmanned aerial vehicle for agricultural spraying, which includes an unmanned aerial vehicle and a medicine water tank with a spraying device, wherein the bottom end of the unmanned aerial vehicle is connected to a mounting frame, the bottom end of the mounting frame is provided with a horizontal slide groove, and the bottom end of the mounting frame is symmetrically engaged and slidably connected to two connecting frames through the slide groove, and the inner side of each connecting frame is connected to an arc-shaped bar, and the two arc-shaped bars can cooperate to form a limiting ring; the outer side of the medicine water tank is fixedly sleeved with two limiting rings, and a limiting groove adapted to the limiting ring is formed between the two limiting rings; and a fixing mechanism for fixing the connecting frame is provided on the mounting frame. The two arc-shaped bars of the utility model can cooperate to form a limiting ring engaged with the limiting groove, and at the same time, under the action of the fixing mechanism, the mounting frame is fixed, so that the limiting ring is fixed, so that the entire medicine water tank can be fixed and easily removed.

[0004] In the above patent, the purpose of facilitating the loading and unloading of the medicine tank is mainly achieved by clamping two connecting frames inward at the same time and cooperating with the fastening knob to be embedded in the connecting hole. However, this method of loading and unloading the medicine tank, due to the fixed size of the connecting frame and the fixed position of the fastening knob, results in that the agricultural spraying drone can only fix the medicine tank with a single diameter limit groove on the top, thereby causing the user's choice of medicine tank to be greatly limited when using the agricultural spraying drone. Summary of the invention

[0005] In view of the above problems, the utility model provides a forest pest control sprayer based on a drone. Through the loader in the loading and unloading device, the forest pest control sprayer based on the drone can conveniently load and unload medicine tanks of different sizes when in use, effectively avoiding the impact on the normal operation of the pest control sprayer caused by the pest control sprayer that can only fix medicine tanks of a single diameter.

The inner side of the device 1 is connected, the inner side of the spring 22 cooperates with the lower end of the bracket 23, a limited dosing cover 112 is installed next to the embedded groove 24, a plurality of sprayers 114 are connected to the limited dosing cover 112, and a medicine tank 113 is engaged with the sprayer 114. The inner side of the limited dosing cover 112 cooperates with the inner side of the sprayer 114, and the upper end of the loading and unloading structure 111 is nested with the inner side of the embedded groove 24. A plurality of moving keys 1112 are installed next to the limited dosing cover 112, and a loading and unloading plate 113 is engaged on the moving key 1112 15. A movable inner groove 1114 is opened next to the loading and unloading plate 1115, and a plurality of electric push rods 1113 are installed next to the movable inner groove 1114. One side of the electric push rod 1113 is engaged with the inner side of the moving key 1112, and the inner side of the moving key 1112 cooperates with the inner side of the movable inner groove 1114. The outer side of the loading and unloading plate 1115 is connected to the inner side of the limiting dosing cover 112, the inner side of the controller 3 is connected to the inner side of the electric push rod 1113, and the outer side of the stabilizing shaft 11114 cooperates with the inner side of the movable inner groove 1114.

[0024] The connecting protrusion key at the top of the loading and unloading structure 111 is consistent in size with the embedding groove 24, so that the connecting protrusion key at the top of the loading and unloading structure 111 can be firmly fixed in the embedding groove 24, and finally fastened by welding.

[0025] The model used by the electric linear actuator 1113 is XDHA24-500. With its advantages such as silent gears, stable base, and low-resistance metal casing, the electric linear actuator 1113 can operate stably and for a long time in the drone-based forestry pest control sprayer.

[0026] The electric push rod 1113 can be firmly fixed on the inner side of the moving key 1112, so that the extension and retraction of the electric push rod 1113 can directly lead the moving key 1112 to extend and retract accordingly.

[0027] The working principle of the present invention is explained as follows: the various mechanical structures inside the drone-based forestry pest control sprayer are all fixed by threads unless otherwise specified. In order to more intuitively observe the professional and technical features in the figure, the bolted connections are appropriately hidden. Before using the drone-based forestry pest control sprayer, the user adds the solution to be sprayed from the limit dosing cap 112 into the medicine tank 113. Since the solution for forestry pest control is a mature existing technology, the present invention does not elaborate on it. When the drone-based forestry pest control sprayer is in use, the user uses the controller 3 to operate the rotor 4 and directly makes the drone fly to the area where the solution needs to be sprayed. When the drone-based forestry pest control sprayer needs to land, it is supported by the bracket 23 for landing, and is safely buffered by the spring 22. When the drone-based forestry pest control sprayer runs to the spraying area , the solution in the medicine tank 113 is evenly sprayed by the sprayer 114. When the solution in the medicine tank 113 is sprayed, the forestry pest control sprayer based on the drone flies back to the starting point. At this time, the user controls the electric push rod 1113 to start to shrink. The shrinking electric push rod 1113 will directly shrink with the moving key 1112 and the loading and unloading plate 1115 in the moving inner groove 1114 to complete the disassembly of the medicine tank 113. At this time, the user will prepare the The limiting dosing cover 112 of the medicine tank 113 is placed on one side of the loading and unloading plate 1115, and the user extends the electric push rod 1113 outward to make the loading and unloading plate 1115 clamp inward. During the inward clamping of the loading and unloading plate 1115, the stabilizing shaft 11114 is rotated around the rotating axis 11112, and the loading and unloading plate 1115 is stably moved in coordination with the rebound of the spring column 11113, so that medicine tanks 113 of different sizes and diameters can be conveniently loaded and unloaded.

[0028] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the utility model is limited by the appended claims rather than the above description, so it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model. Any reference numerals in the claims should not be regarded as limiting the claims involved.
