[0031] In a specific embodiment of this application, the brush structure 18 includes a drive pin 21 and a spiral brush mounted on the drive pin 21; a baffle 15 is provided at one end of the outer casing 13, and a stabilizing pin 17 connected to the drive pin 21 is provided on the baffle 15 to fix the brush structure 18 to the outer casing 13. The spiral brush can remove mold when rotating and can drive the grain to the discharge port 11, realizing the movement and output of grain and mold removal.
[0032] In a further embodiment of this application, the brush structure 18 has spiral-shaped propulsion bristles 23 perpendicular to the drive pin 21 and cleaning bristles 22 perpendicular to the edges of the propulsion bristles 23. Both the propulsion brush and the cleaning brush are specifically nylon brushes. In a specific arrangement, a support shaft can be provided in the middle of the brush structure 18. The propulsion brush consists of bristles arranged spirally around the support shaft, perpendicular to it. The cleaning brush has bristle edges perpendicular to the spiral surface, allowing the arrangement of the propulsion brush and the cleaning brush to increase the contact rate between the brush and the grain, thereby improving cleaning efficiency.
[0033] In a specific embodiment of this application, the driving component includes a geared motor 4, a main drive gear 29 meshing with the motor drive gear 28 of the geared motor 4, and a secondary drive gear 30 meshing with the main drive gear 29. The main drive gear 29 has a square groove at its center, and a square key is provided on the transmission pin 21, which matches and connects with the square groove. A secondary gear fixing pin 37 is fixed inside the housing 13, and a transmission locking button 3 is provided on the secondary gear fixing pin 37 to prevent the secondary drive gear 30 from slipping during motor drive or rocker arm 5 drive. The secondary drive gear 30 is mounted on the transmission locking button 3 via a deep groove ball bearing 16. The main drive gear 29 meshes with the secondary drive gear 30, and the secondary drive gear 30 can rotate around the center of the main drive gear 29, meshing with the motor drive gear 28 or the rocker arm 5 drive gear. A gear cover 2 is provided on the housing 13 to prevent the gear from being exposed and to protect the gear.
[0034] In a further embodiment of this application, the secondary transmission gear 30 is also meshed with the transmission gear of the rocker arm 5; a rocker arm 5 extending from inside the housing 13 is provided on the housing 13, and the transmission gear of the rocker arm 5 is mounted on the rocker arm 5 located inside the housing 13. The rocker arm 5 is provided so that when the reduction motor is not working, the rocker arm 5 can be manually driven to rotate to drive the brush structure 18 to rotate, thereby realizing the removal of mold and conveying of grains.
[0035] Furthermore, the rocker arm 5 located outside the housing 13 is also connected to a handle 6, which facilitates manual operation of the rocker arm 5.
[0036] In a specific embodiment of this application, the filter screen 7 is specifically connected to the outer shell 13 as follows: the edge of the filter screen 7 has a filter screen frame 8, one side edge of the filter screen frame 8 is provided with a plurality of screen frame positioning pins 24, the other side edge of the filter screen frame 8 is provided with a screen frame anti-detachment groove 14 and a screen frame fixing buckle 26, and the outer shell 13 is provided with a screen frame anti-detachment buckle 9 that is locked and fixed with the screen frame anti-detachment groove 14, a screen frame positioning hole that matches the screen frame positioning pin 24, and a screen frame fixing groove that matches and positions with the screen frame fixing buckle 26, so as to realize the fixing of the filter screen frame 8 and facilitate disassembly.
[0037] This grain mold remover, while minimizing its size, incorporates a replaceable filter 7, expanding its application range. It can switch between electric and manual modes, allowing it to operate normally even in low-power conditions. The use of a specific type of brush bristle design effectively improves cleaning efficiency. It also features self-cleaning capabilities; in addition to manual disassembly and cleaning, it can automatically clean mold inside the machine using ultraviolet irradiation.
[0038] The working principle of the grain mold removal machine in this application:
[0039] Select the appropriate filter 7 according to the grain size, place a plastic bag for collecting dust under the filter 7, and place a clean container at the discharge port 11. Add the moldy grains (approximately 500g each time) sequentially into the feed port 1 of the mold remover. Turn on the mold remover; the reduction motor 4 will operate, driving the nylon brush structure 18 to rotate via the transmission gears (if the power supply is insufficient, switch to the rocker arm 5 transmission mode for manual cleaning). During rotation, the brush structure 18 pushes the grains towards the discharge port 11, simultaneously brushing the surface of the grains. Just before the grains reach the discharge port 11, the drive mechanism can be controlled to reverse the grains, repeating the mold removal process and increasing the working stroke of the nylon brush structure 18. The mold removed by the brush structure 18 separates from the grains through the filter 7 and falls into the pre-laid plastic bag. To prevent mold from falling back into the clean container, the outer shell 13 and support legs 10 near the discharge port 11 are designed with a closed structure. After the mold removal process is completed, the nylon brush structure 18 will be controlled to rotate continuously, pushing the grain to the discharge port 11 and falling into the pre-placed clean container, thus completing one cleaning cycle.
