[0002] Primary processing of agricultural products is a key link in the agricultural production chain to enhance product added value and ensure quality. Primary processing mainly includes basic treatments such as washing, screening, peeling, cutting, and drying to remove impurities and inedible parts, extend shelf life, and optimize product form. The screening process involves using automated sorting equipment or manual operation to grade agricultural products based on indicators such as size, color, and weight to ensure uniform specifications and stable quality. This lays the foundation for subsequent deep processing or direct sales and is an important support for agricultural modernization and industrial upgrading.

[0003] In the prior art, agricultural product screening devices need to be cleaned and maintained after long-term use. However, the screen mechanism in most screening devices is fixed by bolts, which makes it time-consuming for workers to disassemble and clean it. This is not conducive to cleaning the screen, resulting in low maintenance efficiency of the screening mechanism and affecting the working efficiency of the device. Therefore, in order to solve the above problems, this utility model proposes a screening device for primary processing of agricultural products that is easy to clean. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a screening device for primary processing of agricultural products that is easy to clean. By adjusting the engagement between the limiting block and the groove through the discharge of the electromagnet, the maintenance and disassembly of the screen can be facilitated, thereby cleaning the screening mechanism, avoiding the time-consuming disassembly and assembly, preventing the impact on the working efficiency of the device, and promoting the maintenance of the device, improving maintenance efficiency and reducing the device failure rate.

[0005] This utility model provides the following technical solution: a screening device for primary processing of agricultural products that is easy to clean, comprising a housing, wherein a screen is provided in the inner cavity of the housing, the number of screens being three and vertically equidistantly distributed, a vibrating motor is fixedly installed at the bottom of the screen, and ribs are fixedly installed at the bottom of the screens on both sides of the vibrating motor, with grooves formed at the bottom of the ribs, and six sliding grooves symmetrically formed on the left and right sides of the inner cavity of the housing, each sliding groove fitting into one of the ribs, a cavity being formed at the bottom of the sliding groove, and an electric motor is fixedly installed at the bottom of the cavity. The magnet has springs fixedly installed at the bottom of the cavity and on both sides of the electromagnet. A movable plate is fixedly installed at the extension end of the spring, and an iron plate is fixedly installed at the bottom of the movable plate. A limit block is fixedly installed at the top of the movable plate. The limit block is movably connected to the slide groove and engaged with the groove. The engagement between the limit block and the groove is adjusted by discharging the electromagnet, which facilitates the disassembly and assembly of the screen, thereby cleaning the screening mechanism, avoiding a lot of time, preventing the impact on the working efficiency of the device, and is conducive to the maintenance of the device, improving maintenance efficiency and reducing the failure rate of the device.

[0006] Preferably, the inner cavity of the housing is fixedly equipped with six tracks at equal vertical intervals, and magnets with opposite magnetic poles are laid in sequence in the tracks. An electromagnetic slider is movably connected to the track. A connecting block is fixedly installed on the side of the electromagnetic slider away from the track. A vacuum cleaner is fixedly installed between two connecting blocks. The vacuum cleaner is located directly above the screen. By energizing the electromagnetic slider, it slides on the track, thereby driving the vacuum cleaner to move and adsorb dust and other impurities adhering to the screen.

[0007] Preferably, a suction pipe is fixedly installed on the upper part of the vacuum cleaner, and the middle part of the suction pipe is fixedly sleeved in the inner wall of a cavity of the housing.

A cover plate is movably connected to the front of the dust collection box via a shaft. An inlet is fixedly installed on the upper part of the housing and to the left of the dust collection box. Impurities enter the dust collection box through the suction pipe. The cover plate can be opened to clean the impurities collected in the dust collection box, so as to avoid dust and other impurities interfering with the screening of agricultural products and prevent impurities from accumulating in large quantities on the screen and causing blockage.

[0008] Preferably, a second shell is fixedly installed on the right side of the first shell. Three pipes are provided in the second shell. A waste outlet is provided at the bottom of the inner cavity of the first shell. Four support rods are evenly fixedly installed at the bottom of the first shell and around the waste outlet.

[0009] Compared with the prior art, the advantages of this utility model are as follows:

[0010] 1. By energizing the electromagnet, it attracts the iron sheet, causing the moving plate to move the limiting block, thus breaking the engagement between the limiting block and the groove. At this point, the screen can be removed from the inner cavity of the housing by utilizing the engagement of the ribs and the slide groove, allowing for cleaning and replacement of the screen. During installation, the elastic potential energy of the spring is used to re-engage the limiting block with the groove, achieving quick disassembly and assembly of the screen.

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

[0018] Please see Figures 1-4A screening device for primary processing of agricultural products, which is easy to clean, includes a housing 1. Three screens 2 are installed inside the housing 1, arranged vertically and equidistantly. A vibrating motor 3 is fixedly installed at the bottom of each screen 2. Ribs 4 are fixedly installed on the bottom of each screen 2, located to the left and right of the vibrating motor 3. Grooves 5 are formed at the bottom of the ribs 4. Six sliding grooves 6 are symmetrically formed on the left and right sides of the inner cavity of the housing 1, each fitting into one of the ribs 4. A cavity 7 is formed at the bottom of each sliding groove 6. An electromagnet 8 is fixedly installed at the bottom of the cavity 7. Springs 9 are fixedly installed on the bottom of the cavity 7, located to the left and right of the electromagnet 8. A movable plate 10 is fixedly installed at the extension end of each spring 9. An iron plate 11 is fixedly installed at the bottom of the movable plate 10. A limiting block 12 is fixedly installed on the upper part of the movable plate 10. The limiting block 12 is movably connected to the sliding grooves 6 and engages with the grooves 5. When agricultural products are placed into the inner cavity of the housing 1, they fall onto the screens 2. The vibrating motor 3 is then activated to drive the screens. The screen 2 vibrates, thus screening agricultural products. As the three screens 2 screen in sequence, agricultural products of different specifications slide out along the slope of the screen 2. When the screen 2 needs to be maintained or replaced, the electromagnet 8 is energized to attract the iron plate 11, which drives the moving plate 10 to descend. The spring 9 is compressed to generate elastic potential energy. The moving plate 10 drives the limiting block 12 into the cavity 7, breaking the engagement between the limiting block 12 and the groove 5. At this time, the cover plate 25 is opened and the screen 2 can be removed from the inner cavity of the housing 1 through the engagement of the rib 4 and the slide groove 6, so that the screen 2 can be cleaned and replaced. During installation, the elastic potential energy of the spring 9 is used to make the limiting block 12 and the groove 5 re-engage, completing the fixation of the screen 2. This realizes the quick disassembly and assembly of the screen 2, which is convenient for cleaning the screening mechanism, avoiding a lot of time spent on disassembly and maintenance, preventing the impact on the working efficiency of the device, and facilitating the maintenance of the device by the staff. This effectively improves the maintenance efficiency of the screening mechanism and reduces the failure rate of the device.

[0019] Six tracks 13 are fixedly installed in the front and rear sections of the inner cavity of the housing 1, arranged vertically and equidistantly. Magnets with opposite magnetic poles are sequentially laid in the tracks 13. Electromagnetic sliders 14 are movably connected to the tracks 13. A connecting block 15 is fixedly installed on the side of the electromagnetic slider 14 away from the track 13. A vacuum cleaner 16 is fixedly installed between two connecting blocks 15, located directly above the screen 2. A suction pipe 17 is fixedly installed on the upper part of the vacuum cleaner 16, and the middle part of the suction pipe 17 is fixedly sleeved in the inner wall of the cavity of the housing 1. A dust collection box 18 is fixedly connected to the top of the suction pipe 17, and the dust collection box 18 is fixedly installed on the upper part of the housing 1. The front of the dust collection box 18 is connected to an axle. A cover plate 19 is connected to the housing. An inlet 20 is fixedly installed on the upper part of the housing 1, to the left of the dust collection box 18. A housing 21 is fixedly installed on the right side of the housing 1. Three pipes 22 are provided inside the housing 21. A waste outlet 23 is provided at the bottom of the inner cavity of the housing 1. Four support rods 24 are evenly fixedly installed around the waste outlet 23 at the bottom of the housing 1. A cover plate 25 is movably connected to the front of the housing 1 via a shaft. Three cover plates 25 are vertically and equidistantly distributed. Two handrails 26 are fixedly installed at the front of the cover plates 25, symmetrically distributed on the left and right. Agricultural products are fed through the inlet 20. The agricultural products of different specifications are placed inside the shell 1 and, after screening, are discharged through three pipes 22. The screened impurities are discharged through the waste outlet 23. After the device has finished operating, the vacuum cleaner 16 is started and the electromagnetic slider 14 is energized. Because magnets with opposite poles are sequentially laid in the track 13, energizing the electromagnetic slider 14 generates a repulsive magnetic force with the magnets on the track 13, thus pushing the electromagnetic slider 14 to move. When the electromagnetic slider 14 moves to the next track 13 with the opposite magnetic pole, the electromagnetic slider 14 is energized in the opposite direction, maintaining a repulsive magnetic force between the electromagnetic slider 14 and the track 13, thus achieving continuous movement of the electromagnetic slider 14. When the electromagnetic slider 14 needs to be stopped... Without changing the direction of the current on the electromagnetic slider 14, it attracts the magnets laid on the track 13, thereby fixing the electromagnetic slider 14. The sliding of the electromagnetic slider 14 on the track 13 drives the vacuum cleaner 16 to move, allowing the vacuum cleaner 16 to adsorb dust and other impurities adhering to the screen 2. The impurities enter the dust collection box 18 through the suction pipe 17. The cover 19 can be opened to clean the impurities collected in the dust collection box 18, preventing dust and other impurities from interfering with the screening of agricultural products, preventing impurities from accumulating on the screen 2 and causing blockage, ensuring the screening efficiency of the device, effectively solving the problem of incomplete screening after long-term use of the device, and improving the durability of the device.

[0020] Working Principle: Agricultural products are placed into the inner cavity of the housing 1 through the inlet 20, causing them to fall onto the screens 2. The vibrating motor 3 is started, causing the screens 2 to vibrate, thus screening the agricultural products. As the three screens 2 are used in sequence, agricultural products of different sizes slide out along the slope of the screens 2 and are discharged through the three pipes 22. Impurities screened out on the screens 2 are discharged through the waste outlet 23. After the device has finished operating, the vacuum cleaner 16 is started and the electromagnetic slider 14 is energized. Since magnets with opposite magnetic poles are laid in the track 13, the electromagnetic slider 14 is energized to generate a magnetic force that repels the magnets on the track 13, thus pushing the electromagnetic slider 14 to move. When the electromagnetic slider 14 moves to the next track 13 with opposite magnetic poles, the electromagnetic slider 14 is energized in the opposite direction to maintain a repulsive magnetic force between the electromagnetic slider 14 and the track 13, thus enabling the electromagnetic slider 14 to move continuously. When the electromagnetic slider 14 needs to stop, the current on the electromagnetic slider 14 is not changed. The direction is adjusted so that the electromagnetic slider 14 is attracted to the magnets laid on the track 13, thereby fixing the electromagnetic slider 14. The sliding of the electromagnetic slider 14 on the track 13 drives the vacuum cleaner 16 to move, so that the vacuum cleaner 16 can adsorb the dust and other impurities adhering to the screen 2. The impurities enter the dust collection box 18 through the suction pipe 17. The cover plate 19 can be opened to clean the impurities collected in the dust collection box 18. When the screen 2 needs to be maintained or replaced, the electromagnet 8 is energized so that it attracts the iron piece 11, which drives the moving plate 10 to descend. The spring 9 is compressed to generate elastic potential energy. The moving plate 10 drives the limiting block 12 into the cavity 7, breaking the engagement between the limiting block 12 and the groove 5. At this time, the cover plate 25 is opened and the screen 2 can be taken out from the inner cavity of the housing 1 through the engagement of the rib 4 and the slide groove 6, so as to clean and replace the screen 2. During installation, the elastic potential energy of the spring 9 is used to make the limiting block 12 and the groove 5 re-engage, thus completing the fixation of the screen 2.
