Description

Technical Field

[0001] The invention belongs to the technical field of pest control, and in particular relates to a spray device for controlling pests and a use method thereof. Background Art

[0002] Trees with edible fruits are called fruit trees, such as apple trees, pear trees, citrus trees, apricot trees, peach trees, etc. At present, with the change of seasons and the damage of mosquitoes, the nutrition of fruit trees is scarce, which reduces the growth life of fruit trees and slows down the growth rate of fruit trees. In severe cases, it may cause fruit trees to wither and die, affecting the economic efficiency of orchards. The harm of pests and diseases to agriculture and plant growth is extensive and serious. Pests and diseases can directly damage the leaves, stems, roots or fruits of plants, resulting in poor crop growth and thus reducing yields. Even if crops can grow to the harvest stage, pests and diseases may still affect their quality, such as the appearance, taste, and nutritional content of fruits. The reduction in crop yield and quality problems will lead to economic losses, including reduced sales revenue and increased costs of controlling pests and diseases. Some pests and diseases not only affect the target crops, but also may affect other plants and animals in the ecosystem, destroying the ecological balance. Some pests and diseases can spread plant diseases, causing the problem to expand to a wider area. Long-term pest and disease problems may lead to changes in soil structure and nutritional content, thus affecting the health of future crops.

[0003] A spraying device for controlling pests and diseases of fruit trees proposed in the patent with publication number CN 114503967 A comprises a bottom plate and a crossbeam, casters are installed at the four corners of the bottom end of the bottom plate, two groups of regulating boxes and a medicine storage tank are installed at the bottom end of the bottom plate, the two groups of regulating boxes are respectively located on the left and right sides of the medicine storage tank, the left end and the right end of the crossbeam are respectively fixedly connected to the top of one end of the two groups of regulating boxes close to the medicine storage tank, high-pressure water pumps are installed on the left and right sides of the top of the crossbeam, the input ends and output ends of the two groups of high-pressure water pumps are both connected to a medicine inlet pipe and a medicine outlet pipe, the tops of the two groups of regulating boxes are both provided with connecting holes that communicate with each other on the left and right, the output ends of the two groups of medicine outlet pipes respectively pass through the two groups of connecting holes, and the input ends of the two groups of medicine inlet pipes pass through the crossbeam and extend into the inner bottom of the medicine storage tank. The present invention increases the spraying area of ​​the fruit trees by providing a series of structures, spraying is more comprehensive and more uniform, and the work efficiency and practicability are improved;

[0004] Traditional fruit tree pest spraying equipment is a mobile cart. When in use, workers need to push the cart to move in the orchard. This spraying method is time-consuming and labor-intensive to implement, and the spraying is not uniform and the spraying efficiency is low. In addition, the capacity of the medicine in the medicine box is generally large. If it is left for a long time, the part with more medicinal properties will sink to the bottom, which will cause the medicine in the box to have uneven medicinal properties, affecting the effect of pest control.

[0005] Therefore, those skilled in the art have proposed a spray device for controlling pests and diseases and a method of using the same to solve the problems raised in the background art.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] (1) The present invention provides an unmanned aerial vehicle (UAV) body with an agent box, which can contain agents for preventing and controlling diseases and insect pests in the agent bin, and controls the UAV body to move to the area to be sprayed through the terminal, and starts the peristaltic pump to spray the agent outward through the nozzle. The nozzle can be rotated on the cross bar by adjusting the rotating drum, thereby adjusting the pitch angle of the nozzle, so as to control the spraying range of the UAV body. There is damping between the adjusting rotating drum and the cross bar, which can achieve the effect of fixed-point hovering, avoiding the angle of the nozzle being offset due to excessive spraying force, and the wind force generated by the UAV body during spraying can drive the stirring rod in the inner bin to rotate, so that the agent can be fully stirred during the flight spraying, avoiding the agent sinking to the bottom and affecting the efficacy.

[0026] (2) The present invention provides a nozzle with a drug outlet barrel and a dispersion barrel. When the drug delivered by the peristaltic pump impacts the propeller plate, it will drive the propeller plate to rotate, and then the dispersion barrel will rotate in coordination with the drug outlet barrel through a movable bearing. The drug will be thrown out by centrifugal force and sprayed out through the mesh plate, thereby expanding the range of drug spraying.

[0027] (3) The present invention can monitor the distribution of fruit trees in the orchard by arranging an image acquisition device under the main body of the drone. Since the row spacing of the fruit trees is different, the concentration effect of the spray demand is also different. After the image acquisition device transmits the row spacing information to the wireless signal receiving module through the wireless signal transmitting module, the built-in micro motor can be started, thereby driving the gear to engage with the tooth groove, thereby realizing automatic adjustment of the angle of the nozzle. When the age of the fruit trees is not large and the tree body is small, resulting in a large planting row spacing, the main body of the drone can be controlled to fly over the fruit trees, and the nozzles at both ends can be controlled to retract inward, which can improve the accuracy of spraying, avoid wasting pesticides, and improve the quality of spraying. When the age of the fruit trees is old and the tree body is large, resulting in a small row spacing, the main body of the drone can be controlled to fly over the middle of the row, and then the nozzles at both ends can be controlled to expand outward respectively, so that the fruit trees on both sides can be sprayed at the same time, thereby improving the spraying efficiency and improving the accuracy and quality of spraying.
