Description

Technical Field

[0001] The invention relates to the technical field of agricultural pest control, in particular to an environmentally friendly agricultural pest control device based on environmental protection. Background Art

[0002] With the advancement of science and technology, agricultural operations are equipped with more and more high-tech equipment, including the use of drones to spray pesticides and eliminate pests. Drones can achieve precise application of pesticides through precise navigation and intelligent control systems, avoiding the problem of overspraying that may exist in traditional methods, thereby reducing the total use of pesticides, quickly covering large areas, and being able to adjust spraying strategies according to the specific conditions of crops, significantly improving the sustainability of agricultural production and the level of environmental protection. However, in the process of using drones to spray pesticides and eliminate pests, the rotating wings of the drones will generate downwash, which will cause the liquid sprayed from the nozzles below to drift, causing environmental pollution or causing pesticide damage to neighboring crops. In addition, if there is wind in the operation area, natural wind will also cause the liquid to drift.

[0003] For example, a drone pesticide spraying device disclosed in Publication No. CN210445442U can increase the stability of the aircraft during the flight spraying process, but the nozzle is close to the wing. The downwash generated by the wing will cause the liquid sprayed from the nozzle below to drift, causing environmental pollution or causing pesticide damage to adjacent crops. A drone pesticide spraying device for crop pests and diseases disclosed in Publication No. CN114223634B can adjust the angle of the nozzle to avoid liquid drift, but it can only be adjusted in the front and rear directions. When there is a lateral crosswind, this problem cannot be avoided, and the adjustment is very troublesome.

[0004] Therefore, an environmentally friendly agricultural insecticide device based on environmental protection is proposed. Summary of the invention

[0051] The present invention provides an environmentally friendly agricultural pest control device based on environmental protection. Compared with the prior art, it has the following beneficial effects:

[0052] (1) The environmentally friendly agricultural pest control equipment based on environmental protection, by filling a storage box with environmentally friendly pesticides such as biological pesticides or low-toxic and high-efficiency chemical pesticides, controls the drone to fly to the farmland where the pesticides need to be sprayed through a controller, and sprays the pesticides in the storage box onto the crops through a hose and a nozzle, thereby performing pest control operations; when the downward pressure flow generated by the drone is strong and causes the sprayed liquid to drift to a non-target area, the nozzle is controlled to move downward to increase the distance between the nozzle and the drone, thereby reducing the impact of the downward pressure flow on the sprayed liquid, improving the spraying accuracy of the liquid, and reducing the operation time required to adjust the distance, which helps to increase the spraying coverage and ensure that the liquid is more evenly distributed on the crop surface. At the same time, the larger distance allows the drone to approach the crops for spraying while maintaining a certain safe distance, especially when close to borders or other sensitive areas, thereby reducing the possibility of accidental spraying to non-target areas.

[0053] (2) This environmentally friendly agricultural insecticide equipment based on environmental protection, after increasing the distance between the nozzle and the machine body, when the sprayed liquid cannot be placed in the target area due to the strong wind in the operation area; when the incoming wind direction is perpendicular to the forward direction of the machine body, the wind will drive the connecting shaft to drive the nozzle to deflect with the connecting shaft as the axial direction; when the incoming wind direction is parallel to the forward direction of the machine body, the wind will drive the movable shaft to drive the nozzle to deflect with the movable shaft as the axis; by adaptively adjusting the inclination angle of the nozzle in real time according to the incoming wind direction, it is more directly directed to the target crop, reducing the drift of the liquid caused by wind, which not only improves the application It improves the spraying accuracy and reduces the impact on non-target areas, reduces the risk of environmental pollution, and can automatically adjust the optimal spraying angle under different wind speeds and wind directions, so that the drone can work safely and effectively in more diverse weather conditions, increases the operation window period, and improves overall work efficiency. Adjusting the nozzle inclination angle can ensure that the liquid medicine is more evenly distributed on the entire crop surface, including the front and back of the leaves, thereby improving the prevention and control effect. Reducing liquid drift and optimizing pesticide use help reduce the impact on the surrounding ecological environment, meet increasingly stringent environmental protection regulations, and promote the development of sustainable agriculture.

[0054] (3) The environmentally friendly agricultural pest control equipment based on environmental protection adjusts the inclination angle of the nozzle according to the direction of the incoming wind; when the incoming wind direction is perpendicular to the forward direction of the machine body, the fixed seat drives the connecting shaft to deflect. When the deflection angle is greater than 45°, the fixed seat can synchronously drive the retaining ring to deform inward as a whole, so that the coverage of the liquid sprayed from the nozzle is smaller under the gathering effect of the retaining ring, so that the droplets of the liquid sprayed from the nozzle are larger, and the degree to which the liquid is affected by the wind is reduced; when the incoming wind direction is parallel to the forward direction of the machine body, the power plate can directly squeeze the driven rod or drive the driven rod to move by squeezing the expansion rod, so that the retaining ring is deformed inward as a whole, thereby changing the droplet size of the sprayed liquid and reducing the degree to which the liquid is affected by the wind; by adaptively changing the state of the liquid sprayed from the nozzle according to the incoming wind direction, it can be optimized according to the real-time wind direction, so that the liquid falls more concentratedly on the target crop, reducing the liquid drift caused by wind. This not only improves the accuracy of pesticide application, but also reduces the impact on non-target areas and the risk of environmental pollution. It can also help protect the sprayed liquid from the impact of the downwash airflow generated by the rotor of the aircraft, allowing the liquid to fall more stably in the target area and reduce drift.

[0055] Other features and advantages of the present invention will be described in the following description, and part of them will become obvious from the description, or will be understood by practicing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures particularly pointed out in the written description and the accompanying drawings.

The pressing plate 57 is driven to move by the pressure rod 59. The pressing plate 57 squeezes the retaining ring 58. The pressing plate 57 and the second positioning rod 55 slide and cooperate, so that the pressing plate 57 can only move linearly along the second positioning rod 55, so that the retaining ring 58 is deformed inward as a whole, so that the coverage of the liquid sprayed by the nozzle 13 is smaller under the gathering effect of the retaining ring 58, so that the liquid sprayed by the nozzle gathers into larger droplets, reducing the degree to which the liquid is affected by the wind. After the wind is reduced, the fixed seat 312 no longer applies an operating force to the pressure rod 59, and the spring three 56 provides the pressing plate 57 with a resetting elastic force to reset it.

[0105] When the incoming wind direction is parallel to the forward direction of the machine body 1, the block 42 drives the main guide rod 4 to move, and the main guide rod 4 drives the power plate 5 to move synchronously. The power plate 5 rotates around the connecting shaft 313, so that the power plate 5 can directly squeeze the driven rod 51 or drive the driven rod 51 to move by squeezing the extension rod 52. The driven rod 51 directly squeezes the squeezing plate 57, so that the retaining ring 58 is deformed inward as a whole, thereby changing the droplet size of the sprayed liquid and reducing the degree to which the liquid is affected by wind.

[0106] In another embodiment different from the aforementioned embodiment, an electric push rod, a hydraulic push rod or a cylinder can be used to directly drive the main support rod 25 to move up and down.
