Description

Technical Field

[0001] This application relates to the field of screening devices, and more particularly to a screening device for herbicide granule raw materials. Background Technology

[0002] Herbicides are widely used in modern agricultural production, playing a crucial role in controlling weed growth and improving crop yield and quality. The quality of herbicide granule raw materials directly affects the effectiveness and safety of herbicides, making screening a key step in the production process.

[0003] Due to factors such as uneven material mixing and unstable granulation temperature and pressure, the size of herbicide granules produced on the market varies considerably, and the particle size is uneven. From the perspective of the raw materials themselves, herbicides have complex compositions, with differences in the physical and chemical properties of different components. This also affects the granule formation and size uniformity. For herbicide granule raw materials with significant size variations, it is difficult to accurately and effectively separate particles of different sizes. Some smaller particles may pass through larger screen openings, while some larger particles may become stuck in the screen, affecting screening efficiency and effectiveness.

[0004] In view of the above-mentioned related technologies, the inventors believe that there is a defect in the screening of herbicide granular raw materials due to large differences in particle size. Therefore, a herbicide granular raw material screening device is proposed to solve the above problems. Utility Model Content

[0005] To address the issue of significant differences in particle size during the screening of herbicide granules, this application provides a herbicide granule raw material screening device.

[0006] The herbicide granule raw material screening device provided in this application adopts the following technical solution:

[0007] A herbicide granule raw material screening device includes a screening device with a discharge port at the bottom center. Several fixed grooves are formed on one side of the inner wall of the screening device. Fixed rods are fixedly connected to the upper and lower ends of the inner walls of the fixed grooves. Several supporting mesh frames are movably installed on the outer surface of the fixed rods. Screening meshes are fixedly installed inside the supporting mesh frames. A stirring mechanism is also provided inside the screening device to agitate the material on the screening mesh. Springs are fitted on the upper and lower ends of the fixed rods at the supporting mesh frames. A distributing port is formed on one side of the inner wall of the screening device between two adjacent supporting mesh frames. A discharge pipe is fixedly installed on the outer surface of the screening device near the distributing port. A vibration mechanism is also provided at the bottom end of the supporting mesh frames extending below the screening device to control the movement of the multiple supporting mesh frames.

[0008] Preferably, the vibration mechanism includes a connecting rod, which is symmetrically welded to the bottom edge of the lowest single support frame. The bottom end of the connecting rod passes through the outside of the screening equipment and is fixed to a connecting frame. A fixed frame is symmetrically welded to the bottom of the screening equipment near the discharge port. A support rotating rod is rotatably installed between the two fixed frames. A second drive motor is installed on one side of the support rotating rod extending to the outside of the fixed frame. Cams are fixed to both sides of the outer surface of the support rotating rod.

[0009] Preferably, the stirring mechanism includes a first drive motor, which is located above the opening at the top of the screening device. The output end of the first drive motor extends through the support mesh frame and into the screening device, where a support shaft is installed. Several stirring blades are welded to the outer surface of the support shaft between two adjacent support mesh frames.

[0010] Preferably, a placement groove is provided on one side of the outer surface of the unloading pipe near the material distribution port, and a limiting plate is inserted into one side of the unloading pipe inside the placement groove, wherein the limiting plate and the opening of the material distribution port are engaged with each other.

[0011] Preferably, the bottom end of the connecting frame is provided with fixing grooves on both sides, and the top of one side of the cam extends into the fixing groove, and the cam and the fixing groove are fitted together.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. By setting up multiple layers of screening screens with different apertures, herbicide granular raw materials can be screened in multiple stages, effectively separating particles of different sizes. Through the cooperation of the limiting plate and the distribution port, the particles screened at different stages can be flexibly controlled to enter the corresponding discharge pipe. The stirring blades of the stirring mechanism rotate under the drive of the No. 1 drive motor, which can move the material on the screening screen, so that the material is evenly distributed on the screening screen, avoiding material accumulation and improving screening efficiency and effect.

[0014] 2. The second drive motor of the vibration mechanism drives the support rod to rotate, which in turn causes the cam to rotate. The interaction between the cam and the fixing groove of the connecting frame causes the support frame to vibrate. This vibration allows particles stuck on the screening mesh to pass through smoothly, further improving the accuracy and efficiency of screening, while also helping to prevent screen clogging.

[0019] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0020] This application discloses a herbicide granule raw material screening device. (Refer to...) Figure 1-3 A herbicide granule raw material screening device includes a screening device 1. A discharge port 2 is located at the center of the bottom of the screening device 1. Several fixing grooves 3 are formed on one side of the inner wall of the screening device 1. Fixing rods 4 are fixedly connected to the upper and lower ends of the inner wall of the fixing grooves 3. Several supporting mesh frames 5 are movably installed on the outer surface of the fixing rods 4. Screening meshes 6 are fixedly installed inside the supporting mesh frames 5. A stirring mechanism is also provided inside the screening device 1 to agitate the material on the screening mesh 6. Springs 7 are fitted on the upper and lower ends of the fixing rods 4 at the outer surface of the supporting mesh frames 5. A distributing port 8 is formed on one side of the inner wall of the screening device 1 between two adjacent supporting mesh frames 5. A discharge pipe 9 is fixedly installed on the outer surface of the screening device 1 near the distributing port 8. A placement groove is formed on one side of the outer surface of the discharge pipe 9 near the distributing port 8. A limiting plate 10 is inserted into one side of the discharge pipe 9 inside the placement groove. The limiting plate 10 and the opening of the distributing port 8 are mutually engaged. A vibration mechanism is also provided at the bottom of the supporting mesh frames 5 extending below the screening device 1 to control the movement of the multiple supporting mesh frames 5.

[0021] Reference Figure 2 and Figure 3 The vibration mechanism includes a connecting rod 14, which is symmetrically welded to the bottom edge of the lowest single support frame 5. The bottom end of the connecting rod 14 passes through the outside of the screening device 1 and is fixed to a connecting frame 15. A fixed frame 16 is symmetrically welded to the bottom of the screening device 1 near the discharge port 2. A support rotating rod 17 is rotatably installed between the two fixed frames 16. A second drive motor 18 is installed on one side of the support rotating rod 17 extending to the outside of the fixed frame 16. Cams 19 are fixed to both sides of the outer surface of the support rotating rod 17. Fixed grooves are opened on both sides of the bottom end of the connecting frame 15. The top of one side of the cam 19 extends into the fixed groove, and the cam 19 and the fixed groove are interlocked.

[0022] Reference Figure 1 and Figure 3The stirring mechanism includes a first drive motor 11, which is located above the top opening of the screening device 1. The output end of the first drive motor 11 extends through the support mesh frame 5 and into the screening device 1, where a support shaft 12 is installed. Several stirring blades 13 are welded to the outer surface of the support shaft 12 between two adjacent support mesh frames 5.

[0023] The implementation principle of the herbicide granule raw material screening device in this application embodiment is as follows: A drive motor 11 is installed above the top opening of the screening device 1, and its bottom output end is connected to a support shaft 12. An agitator 13 is welded to the outer surface of the support shaft 12 between two adjacent support mesh frames 5. When the drive motor 11 starts, it drives the support shaft 12 to rotate, thereby causing the agitator 13 to rotate. During rotation, the agitator 13 agitates the herbicide granule raw material on the screening mesh 6, ensuring that the material is evenly distributed on the screening mesh 6. This avoids material accumulation in localized areas of the screening mesh 6, ensuring that each section of the screening mesh 6 functions effectively, thus improving screening efficiency and effectiveness.

[0024] The screening device 1 has multiple layers of support frames 5 on its inner wall, and each support frame 5 contains a screening screen 6 with different aperture sizes for each layer of screen 6. When the herbicide granules enter the screening device 1, under the influence of gravity, smaller particles pass through the mesh of the upper screening screen 6 and fall into the lower screening screen 6 for further screening, while larger particles remain on the screening screen 6 with the corresponding aperture size. Through this multi-stage screening method, particles of different sizes can be gradually separated, achieving preliminary classification of the herbicide granules.

[0025] The vibration mechanism consists of a connecting rod 14, a connecting frame 15, a fixed frame 16, a supporting rotating rod 17, a second drive motor 18, and a cam 19. The bottom edge of the lowest single supporting mesh frame 5 is symmetrically welded with connecting rods 14, the bottom ends of which pass through the screening device 1 and are fixedly connected to the connecting frame 15. A fixed frame 16 is symmetrically welded to the bottom of the screening device 1 near the discharge port 2. A supporting rotating rod 17 is rotatably mounted between the two fixed frames 16. A second drive motor 18 is mounted on one side of the supporting rotating rod 17 extending outside the fixed frame 16. Cams 19 are fixedly connected to both sides of the outer surface of the supporting rotating rod 17. When the second drive motor 18 starts, it drives the supporting rotating rod 17 to rotate, and the cams 19 on the supporting rotating rod 17 rotate accordingly. Because the cams 19 and the fixing grooves on both sides of the bottom edge of the connecting frame 15 interlock, the rotation of the cams 19 causes the connecting frame 15 to move up and down, which in turn drives the supporting mesh frame 5 to vibrate through the connecting rod 14. Vibration allows particles stuck in the mesh of screening screen 6 to pass through the screen smoothly, avoiding screen blockage. It also makes the movement of particles on screening screen 6 more active, further improving the accuracy and efficiency of screening.

[0026] A material distribution port 8 is provided on one side of the inner wall of the screening device 1, which is located between two adjacent support mesh frames 5. A discharge pipe 9 is fixedly installed on the outer surface of the screening device 1 near the material distribution port 8. A placement groove is provided on one side of the outer surface of the discharge pipe 9 near the material distribution port 8. A limiting plate 10 is inserted into the placement groove, and the limiting plate 10 and the opening of the material distribution port 8 are engaged with each other. Particles of different sizes after screening will enter the discharge pipe 9 through the material distribution port 8. By adjusting the position of the limiting plate 10, the entry of particles of different sizes into the corresponding discharge pipe 9 can be controlled, so as to achieve the classified collection of particles of different sizes.
