[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] A filter device for controlling forest pests and diseases includes a filter box 1. A first coarse filter plate 9, a second fine filter plate 10, and a third fine filter plate 11 are sequentially snapped together between the front wall and the side wall of the filter box 1 from left to right. A cleaning mechanism 8 is fixedly connected to the upper rear end of the filter box 1.

[0027] Lockable movable wheels 2 are fixedly connected to the four corners of the lower end of the filter box 1. A transparent cover plate 4 is installed on the upper rear part of the filter box 1 via a hinge. A water inlet pipe 5 is fixedly connected to the middle of the left end of the filter box 1. A drain pipe 6 is fixedly connected to the lower right end of the filter box 1. Switch valves 7 are provided on the outer surface of the water inlet pipe 5 and the outer surface of the drain pipe 6. Three slots 12 are opened between the front and rear walls of the filter box 1. Four cleaning doors 3 are arranged from left to right on the lower front end of the filter box 1.

[0028] The front and rear sides of the first coarse filter plate 9, the front and rear sides of the second fine filter plate 10, and the front and rear sides of the third fine filter plate 11 are respectively snapped into the slots 12.

[0029] Through the above scheme: Before the forestry pest and disease control operation, the staff operates the lockable movable wheels 2 at the four corners of the lower end of the filter box 1 to move the device to the work site, and then locks the wheels to ensure that the device is in a stable state. Next, the switch valve 7 on the outer surface of the water inlet pipe 5 is opened, and the insecticide containing impurities flows into the filter box 1 through the water inlet pipe 5. The insecticide enters the filter box 1 and passes sequentially through the first coarse filter screen 9, the second fine filter screen 10, and the third fine filter screen 11, which are installed in the slots 12 on the front and rear walls of the filter box 1. These three filter screens form a three-layer filter system. The filtration system has a clear division of labor. The first coarse filter plate 9, with its larger mesh, prioritizes the interception of larger impurities. The insecticide that has passed through this initial filtration continues to flow forward to the second fine filter plate 10, which has a finer mesh and can filter out medium-sized impurities. Finally, the insecticide passes through the third fine filter plate 11, which has the finest mesh, to thoroughly filter out any remaining fine particles, suspended solids, and other impurities. After passing through these three rigorous filtration stages, the insecticide flows out from the drain pipe 6 at the lower right end of the filter box 1. At this point, the valves 7 on the inlet pipe 5 and the drain pipe 6 are closed, completing the filtration process.

[0030] In this embodiment, the cleaning mechanism 8 includes a drive motor 81. The output end of the drive motor 81 passes through the filter housing 1 and is fixedly connected to a positive and negative lead screw 82. The front and rear parts of the outer surfaces of the positive and negative lead screw 82 are respectively movably connected to a first moving plate 83 and a second moving plate 86. The lower ends of the first moving plate 83 and the second moving plate 86 each have three brush grooves 84. The left and right walls of the brush grooves 84 are fixedly connected to several scraper strips 85. The left front end of the first moving plate 83 and the left front end of the second moving plate 86 are jointly installed with a limit guide rod 87. The drive motor 81 is fixedly installed on the upper rear end of the filter housing 1. The first moving plate 83 and the second moving plate 86 are both inverted U-shapes. The structure is such that the first moving plate 83 and the second moving plate 86 are symmetrically distributed front and back. The front and rear ends of the positive and negative lead screws 82 are rotatably connected to the front and rear walls of the filter box 1 through bearings, respectively. The front and rear ends of the limiting guide rods 87 are fixedly connected to the front and rear walls of the filter box 1, respectively, and are arranged parallel to the positive and negative lead screws 82. The brush grooves 84 on the first moving plate 83 and the second moving plate 86 are located on the left and right sides of the first coarse filter plate 9, the second fine filter plate 10, and the third fine filter plate 11, respectively. The scraper strips 85 are vertically equidistantly distributed, and the other end of the scraper strips 85 is in close contact with the upper surface of the first coarse filter plate 9, the second fine filter plate 10, and the third fine filter plate 11.

[0031] Through the above scheme: when the first coarse filter plate 9, the second fine filter plate 10, and the third fine filter plate 11 in the filter box 1 affect the filtration effect due to excessive interception of impurities, the drive motor 81, which is fixedly installed at the upper rear end of the filter box 1, is activated. Its output end drives the positive and negative lead screw 82 to rotate. The front and rear ends of the positive and negative lead screw 82 are rotatably connected to the front and rear walls of the filter box 1 through bearings. The first moving plate 83 and the second moving plate 86 are arranged in an inverted mountain shape and are symmetrically distributed front and rear. They are movably connected to the front and rear parts of the outer surface of the positive and negative lead screw 82, respectively. Under the guidance of the limiting guide rod 87, which is parallel to the positive and negative lead screw 82 and whose two ends are fixed to the front and rear walls of the filter box 1, they move relative to or away from the positive and negative lead screw 82. The brush groove 84 at the lower end of the 6 is located on both sides of the three filter screen plates. The vertically equidistant scraper strips 85 in the brush groove 84 are in close contact with the upper surface of the filter screen plates. During the movement, the scraper strips 85 scrape off the impurities on the surface of the filter screen, realizing automatic cleaning. This cleaning mechanism 8 realizes automatic cleaning of the first coarse filter screen plate 9, the second fine filter screen plate 10 and the third fine filter screen plate 11 through mechanical structure, reducing the tediousness of manual disassembly and cleaning. The inverted mountain-shaped moving plate and multiple sets of scraper strips 85 work together to fully cover the surface of the first coarse filter screen plate 9, the second fine filter screen plate 10 and the third fine filter screen plate 11, and the cleaning effect is thorough. The design of the limit guide rod 87 and the positive and negative screw rods 82 ensures the stability and accuracy of the moving plate movement, ensuring the continuous and efficient operation of the pesticide filtration.

[0032] It should be noted that this utility model is an insecticide filtration device for forestry pest and disease control. First, the filter box 1 is moved to a designated position and locked using the lockable wheels 2. Then, the valve 7 on the outer surface of the inlet pipe 5 is opened, allowing the insecticide containing impurities to flow in through the inlet pipe 5. It then passes sequentially through a first coarse filter plate 9, a second fine filter plate 10, and a third fine filter plate 11, all locked within the slot 12. This achieves three-stage filtration of large-volume impurities, medium-sized particles, and fine suspended matter. The first-stage 10mm large-mesh filter quickly intercepts macroscopic impurities such as leaves and insects. The second-stage 5mm medium-mesh filter removes medium-sized impurities such as mud and crystalline particles. The third-stage 0.5mm microporous filter removes suspended particles. The filtered insecticide flows out through the drain pipe 6. Closing the valve 7 completes the filtration process. When the filter screen traps too many impurities, affecting the filtration effect, the drive motor 81 installed at the upper rear end of the filter box 1 is activated. It drives the positive and negative lead screws 82 to rotate, causing the first moving plate 83 and the second moving plate 86, which are movably connected to the positive and negative lead screws 82, to move relative to or away from each other under the guidance of the limit guide rod 87. The vertically equidistant scraper strips 85 in the brush grooves 84 at the lower end of the two moving plates, which are symmetrically distributed in an inverted mountain shape, are in close contact with the three filter screen plates, scraping off the impurities and completing the cleaning. The vertically equidistant polyurethane scraper strips 85 form an elastic contact pressure of 5-8N with the filter screen, which effectively removes impurities and avoids damage to the screen plates. The fallen impurities are at the bottom of the filter box 1. The four cleaning doors 3 at the lower front end can be opened for cleaning. In addition, the staff can observe the internal situation through the transparent cover 4.
