Description

Technical Field

[0001] This invention relates to the field of plant protection equipment, and more particularly to a plant protection device with pest and disease control functions. Background Technology

[0002] Pests and diseases are one of the natural disasters that seriously endanger agricultural production. Large-scale outbreaks and epidemics of plant diseases will have a significant impact on human beings. Pest and disease control is a means taken by humans to reduce or prevent pathogenic microorganisms and pests from harming crops or livestock.

[0003] In general plant disease and pest control, pesticide solutions are usually mixed first, then diluted with water, and then sprayed onto the plants by operators. However, because the pesticide solution is sprayed onto the plants, it diffuses into the air. When operators inhale the solution, the toxic components and irritating odors in the solution seriously endanger their health. In order to avoid the limited effectiveness of pest and disease control caused by a single pesticide, two or three pesticides are usually mixed. However, when different types of pesticides are mixed, if some pesticides are not used in time after mixing, the active ingredients in the solution will crystallize and precipitate, resulting in precipitation or stratification, which will affect the insecticidal effect of the solution.

[0051] Working principle:

[0052] Preparation phase:

[0053] See the attached diagram, in which Figures 1 to 6 The specific implementation process shown is as follows:

[0054] First, place the plant protection device stably on a level surface. Then, connect the power supply to the flight component 3 to charge the mobile power source inside the flight component 3. After charging is complete, disconnect the power supply. It is generally used for the prevention and control of plant diseases and pests. To avoid the limited effectiveness of a single pesticide in controlling plant diseases and pests, it is generally prepared by mixing 2-3 pesticides. Since different types of pesticides need to be mixed to control different plant diseases and pests, if some pesticides are mixed and not used in time, the active ingredients in the solution will crystallize and precipitate, reducing the killing effect on diseases and pests. It will also leave impurities in the mixed solution chamber, making it difficult to clean and affecting subsequent use, contaminating the solution used later. Therefore, to avoid such phenomena, the solution should be prepared and used immediately to reduce the precipitation of active ingredients.

[0055] Next, different pesticides are injected into the respective storage chambers 10104 through the first injection hopper 102. If only two pesticide solutions need to be mixed, they are injected first into the two side storage chambers 10104. If three pesticide solutions need to be mixed, the third pesticide solution is injected last into the middle storage chamber 10104. Then, the first injection hoppers 102 are covered to prevent the irritating odor of pesticides from escaping into the air and harming human health. Next, tap water is injected into the clean water chamber 10106 through the second injection hopper 103, and then the lid of the second injection hopper 103 is closed. Finally, the start / stop function is activated. The flight component 3 enables the plant protection device to fly into the air, allowing it to spray pesticides onto plants in areas requiring pest and disease control from the air. Utilizing the device's ease of movement in the air, the area covered by pest and disease control is effectively increased, and the time required for comprehensive spraying is reduced, thus improving work efficiency. The flight component 3 flies along a pre-set route, further reducing manual intervention and the time workers spend in contact with pesticides, minimizing the impact on their health.

[0056] Drug mixing stage:

[0057] See the attached diagram, in which Figures 4 to 10 The specific implementation process shown is as follows:

[0058] Once the plant protection equipment reaches the plant requiring pest and disease control, the flight component 3 is controlled to hover the equipment in the air. When three pesticide solutions need to be mixed, the first electric actuator 1010 is activated, retracting and simultaneously driving the lifting plate 109 upward via the second support rod 108. The lifting plate 109 raises the liquid level of the pesticide in the storage chamber 10104. When only two pesticide solutions need to be mixed, the two electric sliders 105 are each moved upward on an electric slide rail 104. Each of the two electric sliders 105 drives a connecting rod 107 upward via the first support rod 106. The two connecting rods 107 then drive a connecting rod 107 upward via the second support rod 108. A lifting plate 109 is moved upwards. When the lifting plate 109 moves upwards, it raises the liquid level of the pesticide in the storage tank 10104. When the liquid level reaches the opening of the guide pipe 10107, the pesticide in the storage tank 10104 enters the mixing tank 10105 along the guide pipe 10107. When three pesticides are being mixed, some pesticides have a priority order for mixing. At this time, by controlling the asynchronous movement of the two electric sliders 105 and the first electric actuator 1010, the pesticide in each storage tank 10104 can be made to enter the mixing tank 10105 in sequence. At this time, the initial mixing of different pesticides has been completed.

[0059] Next, the control activates two third electric actuators 201, which extend and simultaneously drive two fourth support rods 203 to the right via the connecting plate 202. The two fourth support rods 203 together drive the scraper 204 to drive the movable plate 206 to the right. At this time, the scraper 204 moves upward along the inclined surface of the wedge plate 205, simultaneously scraping the liquid medicine in the mixing chamber 10105 to the right. Then, the movable plate 206 stops before contacting the contact block 301. Then, the control activates two second electric actuators 1011, which retract and simultaneously drive two third support rods 1013 downward via the T-shaped plate 1012. All four... The third support rod 1013 drives the pressure plate 1014 to move downwards. The pressure plate 1014 applies downward pressure to the tap water in the clear water tank 10106. When the tap water in the clear water tank 10106 is subjected to downward pressure from the pressure plate 1014, the tap water in the clear water tank 10106 enters the transfer member 1015 through the openings of the three transfer members 1015, and then enters each vertical pipe 1016 through the transfer member 1015. The three vertical pipes 1016 spray the tap water to the left. The tap water falls on the mixed medicine solution scraped together by the scraper 204 and the movable plate 206, diluting the medicine solution. Then, as the liquid level of the mixed medicine solution rises, the two third electric actuators 201 slowly retract, synchronously... The scraper 204 and movable plate 206 are moved to the left along the wedge plate 205, keeping the liquid level of the mixed solution at a certain height. When the scraper 204 contacts the first partition 10102, the second electric actuator 1011 is controlled to close, that is, the water tank 10106 is stopped from being pressed into the mixing tank 10105. At this point, only the dilution of the solution is completed, and the solution is not yet fully mixed. Therefore, the third electric actuator 201 is controlled to extend, simultaneously moving the scraper 204 and movable plate 206 to the right. When the scraper 204 and movable plate 206 move to the right, they also scrape the solution to the right. Since the scraper 204 and movable plate 206 are moving along the wedge plate 205, the solution is further diluted. As the inclined plane of plate 205 moves to the right, the volume of space to the right of scraper 204 and movable plate 206 in the mixing chamber 10105 decreases during the movement of the mixed liquid to the right, and the liquid level of the mixed liquid gradually rises. At this time, by reducing the volume of space occupied by the mixed liquid, the liquid level of the mixed liquid is increased, so that the upper and lower layers of the mixed liquid are mixed with each other. In addition, during the movement, the mixed liquid is mixed with each other in the horizontal direction. Then, by controlling the two third electric actuators 201 to retract, the scraper 204 and movable plate 206 are moved to the left, and the mixed liquid also moves to the left, so that the liquid is fully mixed in the left and right directions. The above operation is repeated until the liquid is fully mixed.

[0060] Spraying stage:

[0061] See the attached diagram, in which Figures 10 to 14 The specific implementation process shown is as follows:

[0062] After the pesticide solution is mixed, to prevent the effective components from leaching out, it needs to be sprayed onto the plants below. During mixing, the pesticide solution is always to the right of the scraper 204, so it needs to be discharged from the mixing chamber 10105. At this point, two third electric actuators 201 are activated, extending and simultaneously driving the scraper 204 and the movable plate 206 to the right. After the movable plate 206 contacts the four contact blocks 301, it continues to move to the right without stopping. The movable plate 206 is then pressed against the wave spring elastic element 306. The elastic element 306 is short and thick, and it is deformed under pressure. The pin fixing the elastic element 306 moves up and down on the scraper 204, achieving elasticity. The elastic element 306 extends and deforms vertically, becoming slender. Simultaneously, the movable plate 206 drives several hollow cylinders 307 to move to the left. At this time, the hollow cylinders 307 move to the left within the sleeve 308 until the drain outlet on the left side of the hollow cylinder 307 emerges from the sleeve 308. At this point, the two third electric actuators 201 are shut off. Meanwhile, the liquid medicine on the right side of the scraper 204 and the movable plate 206 is transferred to the left side of the scraper 204 and the movable plate 206 through the drain outlet on the left side of the hollow cylinder 307. Since the drain outlet on the left side of the hollow cylinder 307 is located in a front-to-back relative position, the liquid medicine is sprayed out from the front-to-back direction of the left side of the hollow cylinder 307. At this time, the liquid medicine sprayed out by two adjacent hollow cylinders 307 cross-mixes with each other in the space on opposite sides, achieving uniform mixing of the liquid medicine in the front-to-back direction.

[0063] When the liquid medicine enters the left side of the scraper 204 and the movable plate 206, the liquid medicine flows along the wedge plate 205. When the liquid medicine comes into contact with the first partition 10102, the liquid medicine enters the discharge bin 10109 from the discharge port 10108. At this time, the pump 302 is started. The pump 302 draws out the liquid medicine in the discharge bin 10109 through the conduit 303, and then introduces it into two rows of nozzles 305 through the diversion pipe 304. The two rows of nozzles 305 spray the liquid medicine downwards at the same time, realizing large-area liquid medicine spraying on the plants below, effectively preventing plant diseases and pests. The timely spraying of the liquid medicine by the pump 302 effectively avoids the residue of the liquid medicine in the medicine tank 101.
