[0002] Biological control is a method of controlling pests and diseases in farmland and forests using beneficial organisms. It has advantages such as not polluting the environment and leaving no pesticide residues, and is widely used in the development of sustainable agriculture. For example, Trichogramma wasps are egg-parasitic insects that can eliminate pests before they hatch and cause damage. They have a strong pest control ability and are often used to control agricultural and forestry pests such as pine caterpillars and corn borers. They are used on a large scale year-round in Northeast China, the Huang-Huai-Hai Plain, and other regions.

[0026] The drone body 100 and the delivery mechanism 200 include a connecting component 210 and a storage housing 220. The top of the connecting component 210 is fixedly connected to the bottom of the drone body 100, and the bottom of the connecting component 210 is locked to the top two sides of the storage housing 220. The storage housing 220 includes a storage compartment 221, the bottom of which is connected to a protective cover 222, and the bottom of the protective cover 222 is connected to a discharge bottom cylinder 223. A discharge buffer tube 226 is provided between the storage compartment 221, the protective cover 222, and the discharge bottom cylinder 223. A synchronous delivery component 230 is provided inside the storage housing 220. The synchronous delivery component 230 includes a feeding rod 235 and a discharge ratchet 236.

A connecting block is provided on the top of the positive locking plate 216. The bottom inner side of the positive locking plate 216 is connected to the top sides of the storage compartment 221. A side locking plate 217 is connected to the top outer side of the positive locking plate 216. A sliding plate 215 is limited and slidably connected to the outer side of the side locking plate 217. The top of the sliding plate 215 is engaged with the guide rail 212. The positive locking plate 216 is used to ensure reliable connection.

[0028] The bottom of the slide plate 215 is provided with a limiting plate 219 that slides through it. The limiting plate 219 is fixedly installed on the side plate 217. The external thread of the limiting plate 219 is provided with a bolt 218 that abuts against the slide plate 215. The top of the slide plate 215 is fixedly connected to a connecting plate 213. The two sides of the connecting plate 213 are elastically connected with elastic clips 214. The elastic clips 214 are correspondingly engaged with two sets of guide rails 212. The installation position can be easily and flexibly selected with the help of the elastic clips 214.

[0029] Please see Figure 4 and Figure 5 The storage housing 220 also includes an upper inner plate 224, which is fixedly installed at the bottom of the storage chamber 221. The outer wall of the protective cover 222 is provided with through holes. The top of the protective cover 222 is fixedly connected to the bottom of the upper inner plate 224, and the bottom of the protective cover 222 is fixedly connected to the top of the discharge bottom cylinder 223. The bottom of the discharge bottom cylinder 223 is fixedly connected to the bottom plate 225. The storage chamber 221 is in the shape of an inverted isosceles trapezoid, so that the material to be fed will slide down stably and will not accumulate.

[0030] One side of the upper inner plate 224 has a through hole that mates with the top of the discharge buffer tube 226. The top of the discharge bottom cylinder 223 has a through hole that mates with the discharge buffer tube 226. The bottom plate 225 has the same through hole as the discharge buffer tube 226. After the Trichogramma eggs are put into the discharge buffer tube 226, they will line up to facilitate stable feeding. Multiple support rods 227 are evenly connected between the top of the discharge bottom cylinder 223 and the bottom of the upper inner plate 224.

[0031] The synchronous delivery component 230 includes a servo motor 231, which is located inside the protective cover 222. The top of the servo motor 231 is connected to an upper connecting shaft 232, which is limited to rotate through the middle of the upper inner plate 224. The top of the upper connecting shaft 232 is connected to a feeding rod 235, which is correspondingly set with the top through hole of the discharge buffer tube 226. A coupling 233 is provided on one side of the servo motor 231. The coupling 233 is U-shaped. The top of the coupling 233 is driven and sleeved to the outside of the upper connecting shaft 232. The bottom of the coupling 233 is driven and connected to the lower connecting shaft 234. The bottom of the lower connecting shaft 234 is limited and rotated through the top of the discharge bottom cylinder 223. The bottom of the upper inner plate 224 is driven and connected to the discharge ratchet 236. The feeding rod 235 continuously agitates the incoming material at the bottom of the storage bin 221 to prevent the incoming material from arching in the storage bin 221 and stably pushes the incoming material into the discharge buffer tube 226.

[0032] Servo 231 is controlled by a microcontroller or remote control technology, which are currently available.

[0033] The coupling 233 enables the servo motor 231 to simultaneously drive the feed lever 235 and the discharge ratchet 236 to move within a certain angular range. An arc-shaped through hole is provided on one side of the discharge ratchet 236, corresponding to the bottom through hole of the discharge buffer tube 226 and the through hole of the base plate 225. A certain gap exists between the discharge ratchet 236 and the base plate 225, allowing the discharge ratchet 236 to rotate within a certain angular range as the servo motor 231 drives the coupling 233, thus releasing material from the discharge outlet of the discharge buffer tube 226 into the through hole on the base plate 225. A guide slope can be provided around the through hole on the base plate 225 to facilitate material drop.

[0034] Working principle: The top of the connecting component 210 is connected to the bottom of the UAV body 100, and the positive locking plate 216 is connected to the top two sides of the storage compartment 221. The length of the sliding plate 215 extending into the limiting locking plate 219 is adjusted to adjust the position of the storage compartment 221 from the UAV body 100. The Trichogramma eggs are placed inside the storage compartment 221. When the servo motor 231 is started, it will drive the feeding rod 235 to swing. The feeding rod 235 is used to feed the Trichogramma eggs into the discharge buffer tube 226. At the same time, when the feeding rod 235 swings, the coupling 233 will drive the discharge ratchet 236 to swing around the connecting shaft 234. When the groove on one side of the discharge ratchet 236 moves to the bottom of the discharge buffer tube 226, it will catch some of the Trichogramma eggs. When the discharge ratchet 236 moves to the through hole on the bottom plate 225, the Trichogramma eggs fall into the field. This process is repeated.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
