Description

Technical Field

[0001] This utility model relates to the field of plant protection robot technology, specifically to an ozone sterilization device for a plant protection robot. Background Technology

[0002] Plant protection robots are intelligent agricultural devices that integrate artificial intelligence, autonomous driving and precision operation technologies. They are mainly used for plant protection operations such as pest and disease control, pesticide spraying and vegetation monitoring. Ozone, as a broad-spectrum bactericide, can destroy the structure of microorganisms through strong oxidation. It is also being used in conjunction with plant protection robots to kill pathogens in crops.

[0003] A search revealed an existing patent (publication number: CN220935936U) disclosing a greenhouse ozone sterilization device, relating to the field of greenhouse sterilization technology. The device includes a slide rail installed at the top of the greenhouse, with a slider slidably connected inside the slide rail. A drive mechanism controlling the slider's movement within the slide rail is located inside the slide rail. A movable box is installed at the bottom of the slider, and an ozone generating mechanism is located inside the movable box. Ozone solution is injected into the spray pipe through the ozone generating mechanism inside the movable box and sprayed onto the crops through nozzles. The ozone water kills fungi and bacteria on the crops. A flipping mechanism controls the unfolding angle of the spray pipe, allowing the spraying range to be controlled according to the greenhouse area, improving the device's adaptability. The drive mechanism controls the movement of the movable box inside the greenhouse, replacing manual pushing operations, improving spraying efficiency, and reducing the workload of workers.

[0004] However, the above method is inconvenient for uniform spraying, as it can only spray back and forth, and it is inconvenient to rotate and spray evenly. At the same time, it is inconvenient to stir and mix ozone and water, which is not conducive to the uniformity of ozone dissolving in water, thus making it inconvenient to kill bacteria.

[0005] In view of this, the present invention proposes an ozone sterilization device for a plant protection robot. Utility Model Content

Then, the activated carbon adsorption plate can be removed and replaced through the sealing plate. The overall replacement process is simpler and more convenient, reducing the difficulty of disassembly and replacement for workers. Attached Figure Description

Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example 1

[0028] A preferred embodiment of the ozone sterilization device for the plant protection robot provided by this utility model is, for example... Figures 1 to 6 As shown: An ozone sterilization device for a plant protection robot includes a housing 5; a controller 16 fixedly connected to the lower front end of the housing 5; a water injection pipe 15 fixedly connected to one side of the top of the housing 5; a liquid level sensor 10 fixedly connected to the lower end of one side of the housing 5; an ozone generator 3 fixedly connected to one side of the top of the housing 5; the output end of the ozone generator 3 is connected to the lower end of the interior of the housing 5 through a conduit; a filter box 11 is fixedly connected to the top of the housing 5 on one side of the ozone generator 3; one side of the filter box 11 is connected to the input of the ozone generator 3 through a conduit. The filter box 11 is connected to the other side of the filter box 11, and an air inlet pipe 19 is fixedly connected to it. The filter assembly 12 is mounted on the filter box 11 and is used to filter and remove dust from the air entering the ozone generator 3. The connecting coil 9 is fixedly connected to the lower end of the surface of the box 5. Atomizing nozzles 8 are fixedly connected at equal intervals on both sides of the surface of the connecting coil 9. A water pump 4 is fixedly connected to the upper end of one side of the box 5. The output end of the water pump 4 is connected to one side of the top of the connecting coil 9 through a conduit. The input end of the water pump 4 is connected to the lower end of the inside of the box 5 through a conduit.

[0029] A stirring rod 7 is rotatably connected to the lower end of the inner wall of the box 5. Stirring blades 6 are fixedly connected to the surface of the stirring rod 7 at equal angles. A fixing frame 13 is fixedly connected to the top of the box 5. A fixing plate 2 is set above the fixing frame 13.

The output end of the reduction motor 1 passes through the fixing plate 2 and is fixedly connected to the top of the fixing frame 13 through a coupling. A connecting rod 14 is fixedly connected to the top of the fixing plate 2 at equal angles.

[0030] In this embodiment, the thrust generated by the ozone delivered into the housing 5 causes the stirring blade 6 to rotate around the stirring rod 7, thereby agitating the water at the lower end of the housing 5 and mixing the ozone and water evenly. At the same time, during the spraying process, the reduction motor 1 can be started to drive the fixed frame 13 to rotate, thereby causing the housing 5 to rotate slowly and realize the rotational spraying of the atomizing nozzle 8.

[0031] In a further preferred embodiment of the present invention, an auxiliary groove 18 is provided annularly at the bottom end of the fixed plate 2, and auxiliary blocks 17 that slide and cooperate with the inside of the auxiliary groove 18 are fixedly connected to both ends of the top end of the fixed frame 13.

[0035] Based on Example 1, a preferred embodiment of the ozone sterilization device for the plant protection robot provided by this utility model is, for example... Figures 1 to 6As shown in the figure: The filtering component 12 includes: an installation groove 1205 opened at the top end of the filtering box 11, a sealing plate 1201 is movably connected to the top end of the filtering box 11, installation holes 1206 are opened at both ends on one side of the sealing plate 1201, and an activated carbon adsorption plate 1203 extending into the interior of the filtering box 11 is fixedly connected to the bottom end of the sealing plate 1201; a fixing groove 1204 opened on one side of the top end of the filtering box 11, a sliding rod 1209 is fixedly connected to the inner wall of the fixing groove 1204, a slider 1208 is slidably connected to the surface of the sliding rod 1209, and a mounting block 1207 is fixedly connected to the top end of the slider 1208; a mounting spring 1210 wound around the surface of the sliding rod 1209, and both ends of the mounting spring 1210 are fixedly connected to the inner wall of the fixing groove 1204 and one end of the slider 1208 respectively.

[0036] In this embodiment, the activated carbon adsorption plate 1203 filters and removes dust from the air entering the interior of the filtering box 11, avoiding impurities from affecting the normal operation of the ozone generator 3, and at the same time, the activated carbon adsorption plate 1203 can be taken out and replaced regularly through the sealing plate 1201.

[0037] In a further preferred embodiment of the present utility model, a snap-fit structure is formed between the lower end of the sealing plate 1201 and the lower end inside the installation groove 1205, and the cross-sectional area of the top end of the sealing plate 1201 is larger than the cross-sectional area of the top end of the installation groove 1205.

[0038] In this embodiment, by using the sealing plate 1201 with a larger area, after the sealing plate 1201 is snap-fitted with the inside of the installation groove 1205, the top end of the installation groove 1205 is completely blocked and sealed.

[0039] In a further preferred embodiment of the present utility model, a sealing ring 1202 is fixedly connected to the lower end of the surface of the sealing plate 1201, and the shape of the sealing ring 1202 is a square ring.

[0040] In this embodiment, the sealing ring 1202 is used to improve the sealing performance and fastening performance after the sealing plate 1201 is snap-fitted with the inside of the installation groove 1205.

[0041] In a further preferred embodiment of the present utility model, the shape of the mounting block 1207 is U-shaped, and a snap-fit structure is formed between one end of the mounting block 1207 and the inside of the installation hole 1206.

[0042] In this embodiment, by using the snap-fit between the U-shaped mounting block 1207 and the inside of the installation hole 1206, the firmness of the sealing plate 1201 after snap-fitting installation is ensured.

[0043] In a further preferred embodiment of the present utility model, the shape of the connecting rod 14 is T-shaped, and a reserved bolt hole is opened at the upper end of the connecting rod 14.

[0044] In this embodiment, it is convenient to connect and install this device with an agricultural robot, a mobile mechanism, or a fixed mechanism.

[0045] The working principle of this device is as follows: First, the device is connected and installed with the plant protection robot, mobile mechanism or fixed mechanism using the connecting rod 14 and external bolts. Then, an appropriate amount of water is injected into the tank 5 through the water injection pipe 15, and the water level sensor 10 is used to detect the water level inside the tank 5 in real time to prevent the water pump 4 from running dry due to the low water level. Then, the ozone generator 3 is used to deliver ozone into the tank 5. At this time, the force of the ozone delivery will cause the stirring blade 6 to rotate around the stirring rod 7 as the axis, which can stir the water at the lower end of the tank 5 and achieve the mixing of ozone and water.

[0046] Then, the water pump 4 is started to deliver the mixed ozone water to the inside of the connecting coil 9, and then it is atomized and sprayed out by the atomizing nozzle 8. During the spraying process, the reduction motor 1 can be started to drive the fixed frame 13 to rotate, thereby causing the box 5 to rotate slowly, realizing the rotation spraying of the atomizing nozzle 8, improving the spraying range and spraying uniformity.

[0047] Simultaneously, during the operation of the ozone generator 3, external air is drawn in through the filter box 11 and the air inlet pipe 19. At this time, the activated carbon adsorption plate 1203 filters and removes dust from the air entering the filter box 11, preventing impurities from affecting the normal operation of the ozone generator 3. Furthermore, the mounting block 1207 can be periodically moved to allow the slider 1208 to slide on the surface of the slide rod 1209, compressing the mounting spring 1210, until the mounting block 1207 slides completely out of the mounting hole 1206. Afterwards, the activated carbon adsorption plate 1201 can be used to seal the activated carbon adsorption plate 1206. 203 is removed and replaced. During installation, first move the mounting block 1207, then place the activated carbon adsorption plate 1203 into the filter box 11 through the mounting groove 1205. Use the sealing ring 1202 to improve the sealing and tightness of the sealing plate 1201 after it is engaged with the inside of the mounting groove 1205. At the same time, loosen the mounting block 1207. Use the elastic force of the mounting spring 1210 to make the slider 1208 slide and drive the mounting block 1207 to slide into the mounting hole 1206, ensuring the firm and stable engagement of the sealing plate 1201.

[0048] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described above, and the electrical connection should be completed by referring to the working sequence of each electrical component. The detailed connection methods are well-known technologies in the field. The above mainly introduces the working principle and process, and will not describe the electrical control.
