Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0030] Reference Figures 1-3This utility model provides an embodiment of a square-shaped grain conveying structure, including a conveying shell 1. A reduction motor 2 is fixedly installed at one end of the conveying shell 1 for driving. A rotating shaft 3 is rotatably connected to the inner wall of the conveying shell 1 via bearings. Screw blades 4 are fixedly connected to the surface of the rotating shaft 3. When rotating, the grain can be pushed under the action of friction. Several discharge pipes 5 are fixedly connected to the bottom end of the conveying shell 1 for discharging and conveying the grain to a designated point. An electric butterfly valve 6 is provided in the middle of the discharge pipe 5 for controlling the opening and closing of the discharge pipe 5. The electric setting facilitates remote control. During operation, a mounting base 8 is fixedly embedded at one end of the top of the conveying shell 1. A feeding hopper 7 is installed on the inner wall of the mounting base 8. The hopper-shaped design makes it difficult for the grain to spill during feeding. Vibration motors 13 are fixedly installed on both sides of the middle of the feeding hopper 7 to drive the feeding hopper 7 to shake. A support component is installed on the inner wall of the mounting base 8 to support the feeding hopper 7. A claw 14 is fixedly connected to the four sides of the bottom of the mounting base 8. When the feeding hopper 7 shakes, the claw 14 can move and clear the blocked grain. A dust collection component is installed on one side of the top of the conveying shell 1 to collect the dust generated during feeding.
[0031] Reference Figure 1 and Figure 4 The dust collection assembly includes a dust collection box 17, a fan 18, an air duct 16, a dust collection head 15, and a filter assembly. The dust collection box 17 is fixedly connected to one side of the top of the conveying shell 1 and is used to collect and store dust. The air duct 16 is fixedly connected to one side of the top of the dust collection box 17 for conveying dust. The dust collection head 15 is fixedly connected to the top of the air duct 16 and is fixedly connected to the top of the feed hopper 7 to facilitate the concentrated suction of dust into the air duct 16. The fan 18 is fixedly installed on the front side of the dust collection box 17 for attracting dust. The filter assembly is installed inside the dust collection box 17 for filtering and blocking dust.
[0032] Reference Figure 4 The filter assembly includes a filter screen 19 and a vibration motor 20. The filter screen 19 is snapped into the inside of the dust collection box 17. The filter screen 19 can trap dust in the air and keep it in the dust collection box 17. The vibration motor 20 is fixedly installed on the side of the filter screen 19 near the fan 18. The vibration motor 20 can be periodically activated to shake off the dust on the surface of the filter screen 19, ensuring continuous dust collection.
[0033] Reference Figure 4 The input end of the blower 18 is connected to the inside of the dust collection box 17. After the blower 18 is started, the negative pressure can be used to suck the dust at the feeding point into the dust collection box 17 for easy cleaning.
[0034] Reference Figure 3The support assembly includes two slide grooves 10, two slide bars 11, and several springs 12. The two slide grooves 10 are respectively opened on both sides of the inner wall of the mounting base 8. The inner walls of the two slide grooves 10 are slidably connected with slide bars 11, and the two slide bars 11 are respectively fixedly connected to both sides of the bottom of the feed hopper 7, so that the feed hopper 7 can slide up and down in the mounting base 8. Several springs 12 are fixedly connected to the bottom of the inner walls of the two slide grooves 10. After the vibration motor 13 is started, the vibration amplitude of the feed hopper 7 can be increased with the cooperation of the slide bars 11 and the springs 12, which helps the grain fall.
[0035] Reference Figure 3 The tops of several springs 12 are fixedly connected to the slide bar 11. The springs 12 support the feed hopper 7 so that it can shake up and down.
[0036] Reference Figure 2 The output end of the geared motor 2 is fixedly connected to one end of the rotating shaft 3. After the geared motor 2 is started, it can drive the auger blades 4 on the rotating shaft 3 to rotate, so as to push the grain.
[0037] Reference Figure 1 The top of the conveyor housing 1 is fixed with a maintenance cover 9 by bolts. The maintenance cover 9 can be removed to facilitate cleaning and maintenance of the inside of the conveyor housing 1.
[0038] Working principle: Grain to be conveyed is fed into the feed hopper 7 and then falls into the conveying shell 1. The auger blades 4 on the rotating shaft 3 are rotated by starting the reduction motor 2, which pushes the grain. Multiple discharge pipes 5 are installed below the conveying structure, and the electric butterfly valves 6 can be opened according to the feeding position, making the grain distribution in the flat hopper more even. Periodically starting the vibration motor 13 at the feed hopper 7, with the cooperation of the slide bar 11 and spring 12, increases the vibration amplitude of the feed hopper 7, which helps the grain fall. Simultaneously, multiple claws 14 in the mounting base 8 can be used to adjust the grain... The feeding mechanism is agitated to ensure smooth feeding of grain into the flat silo. A dust collection component is installed at the feeding point of the flat silo's conveying structure. When the feeding hopper 7 shakes, it helps to separate dust from the grain. By starting the fan 18, in conjunction with the air duct 16 and the dust collection head 15, the dust can be sucked into the dust collection box 17 and stored in the box under the protection of the filter screen 19. Cleaning is convenient, and the vibration motor 20 can be periodically started to shake off the dust on the surface of the filter screen 19 to ensure continuous dust collection. The side of the dust collection box 17 has a removable cover for discharging the dust inside the box.
