The servo motor 4 is started to drive the rotating shaft 5 to rotate, and the driving gear 6 rotates accordingly. Since the driving gear 6 and the driven gear 10 are engaged with each other, the rotating shaft 9 is driven to rotate, and the pulling claw 11 on the outer wall of one end of the rotating shaft 9 starts to rotate to pull the betel nuts on the conveyor belt 26. At the same time, the disc 7 at the other end of the rotating shaft 5 follows the rotation, so that the protruding rod 8 slides in the sliding groove 13 inside the connecting rod 12. The action of the protruding rod 8 and the sliding groove 13 limits the angle of rotation of the gear. Under the forward and reverse cooperation of the servo motor 4, the pulling claw 11 swings back and forth on the conveyor belt 26, promoting the flipping of the betel nuts so that each betel nut can be evenly heated.

[0028] See also Figure 1-4As shown, a mounting cavity 14 is installed on the top side of the drying frame 2, an air inlet pipe 15 is installed on the top side of the mounting cavity 14, a threaded groove 16 is provided inside the top end of the air inlet pipe 15, and a filter cartridge 17 is connected to the internal thread of the threaded groove 16; a negative pressure motor 18 is installed on the inner wall of the top side of the mounting cavity 14, and five fan blades 19 are equidistantly installed on the output end of the negative pressure motor 18, and an electric heating plate 20 is installed on the inner wall of the bottom end of the mounting cavity 14, and a connecting pipe 21 is installed on the bottom side of the drying frame 2, and six air blowing pipes 22 are equidistantly installed on the bottom side of the connecting pipe 21, and mounting plates are installed on both sides of the drying frame 2, and a number of door curtains 23 are equidistantly installed on the outer walls of the mounting plates through hinges; when working, during the betel nut processing process By drying, the moisture content in the betel nut is reduced to a certain level, making it more stable and convenient for storage and transportation. Therefore, a drying box is needed. The negative pressure motor 18 is started, driving the fan blades 19 to rotate, generating negative pressure in the installation chamber 14, and the outside air enters from the air inlet pipe 15. At the same time, the filter cartridge 17 filters the air, effectively reducing the entry of dust and maintaining the cleanliness of the air in the drying box. The filtered air enters the installation chamber 14 under the action of negative pressure, and the electric heating plate 20 on the inner wall of the bottom end of the installation chamber 14 is energized and heated, heating the air into hot air. The hot air is blown out from the six blowing pipes 22 on the bottom side through the connecting pipe 21, directly acting on the surface of the betel nut on the conveyor belt 26, accelerating the evaporation of moisture inside the betel nut. When the filter cartridge 17 needs to be cleaned, it is removed from the threaded groove 16.

[0029] See also Figure 1 、 2 As shown in , 3, and 5, a connecting shaft 24 is rotatably installed between both ends of the support frame 1, a rotating roller 25 is installed on the outer wall of the connecting shaft 24, and a conveyor belt 26 is commonly assembled on the outer wall of the rotating roller 25. A conveying motor 27 is installed on one side of the support frame 1, and one end of the connecting shaft 24 is cooperatively connected to the output end of the conveying motor 27;

[0030] Two support shafts 28 are rotatably installed between the two sides of one end of the support frame 1, and cleaning rollers 29 are installed on the outer wall of the support shaft 28. The cleaning rollers 29 are respectively installed on both sides of the bottom end of the conveyor belt 26 and are arranged in contact with the conveyor belt 26. A driving gear 2 30 and a driven gear 2 31 are respectively installed on the outer wall of one end of the support shaft 28, and the driving gear 2 30 and the driven gear 2 31 are meshed with each other. A support 32 is installed on one side of the support frame 1, and a drive motor 33 is installed inside the support 32. One end of the support shaft 28 is connected to the output end of the drive motor 33;

[0031] The bottom side of the support frame 1 is symmetrically fixed with two baffles 34 on the outside of the cleaning roller 29. A collection box 35 is fixed between the two sides of the support frame 1 in the middle gap of the conveyor belt 26. The collection box 35 is composed of four sides, of which the top side and one side are not sealed.

[0032] A movable door 36 is installed on one side of the support frame 1 through a hinge, and a handle 37 is fixed to one side of the movable door 36. During operation, impurities in the betel nut will remain on the conveyor belt 26 during processing, affecting the quality of subsequent betel nut drying. The betel nut is placed on the conveyor belt 26, and the conveying motor 27 is started to drive the connecting shaft 24 to rotate, thereby rotating the rotating roller 25, so that the conveyor belt 26 starts to run. The conveyor belt 26 is a mesh structure, and the betel nut to be dried is conveyed to the drying frame 2 through the door curtain 23. The door curtain 23 reduces heat loss during the drying process and improves the utilization rate of heat energy. Impurities falling from the mesh in the conveyor belt 26 fall into the collection box 35. At the same time, the drive motor 33 is started, driving the support shaft 28 to rotate, and the cleaning roller 29 on the outer wall of the support shaft 28 rotates. Since the driving gear 2 30 and the driven gear 2 31 are engaged with each other, the two cleaning rollers 29 rotate in opposite directions at the same time, cleaning both sides of the bottom end of the conveyor belt 26, effectively removing impurities on the conveyor belt 26, ensuring the cleanliness of the equipment and the quality of the betel nut. At the same time, the baffle 34 prevents the impurities after cleaning from splashing too wide and difficult to clean. When it is necessary to clean the impurities, the movable door 36 can be opened through the handle 37 to clean the impurities in the collection box 35.

[0033] Working principle: Betel nuts are placed on the conveyor belt 26, and the conveyor motor 27 is started, which drives the connecting shaft 24 to rotate, thereby rotating the rotating roller 25, and the conveyor belt 26 starts to run. The conveyor belt 26 has a mesh structure and conveys the betel nuts to be dried through the door curtain 23 to the drying frame 2. The door curtain 23 reduces heat loss during the drying process and improves the utilization rate of heat energy. Impurities that fall through the mesh of the conveyor belt 26 during the conveying process fall into the collection box 35.

[0034] The negative pressure motor 18 starts, driving the fan blades 19 to rotate, generating negative pressure in the installation chamber 14. External air enters from the air inlet pipe 15, and at the same time, the filter cartridge 17 filters the air, effectively reducing the entry of dust and maintaining the cleanliness of the air in the drying box. The filtered air enters the installation chamber 14 under the action of negative pressure, and the electric heating plate 20 on the inner wall of the bottom end of the installation chamber 14 is energized and heated, heating the air into hot air. The hot air is blown out from the six blowing pipes 22 on the bottom side through the connecting pipe 21, directly acting on the surface of the betel nuts on the conveyor belt 26, accelerating the evaporation of moisture inside the betel nuts. When the filter cartridge 17 needs to be cleaned, it is removed from the threaded groove 16;

[0035] At the same time, the servo motor 4 is started, driving the rotating shaft 5 to rotate, and the driving gear 1-6 rotates accordingly. Since the driving gear 1-6 and the driven gear 1-10 are meshed with each other, the rotating shaft 9 is driven to rotate, and the scraping claw 11 on the outer wall of one end of the rotating shaft 9 begins to rotate, scraping the betel nuts on the conveyor belt 26. At the same time, the disk 7 at the other end of the rotating shaft 5 rotates accordingly, causing the protruding rod 8 to slide in the chute 13 inside the connecting rod 12. The action of the protruding rod 8 and the chute 13 limits the angle of rotation of the gears. Under the forward and reverse rotation of the servo motor 4, the scraping claw 11 swings back and forth on the conveyor belt 26, promoting the flipping of the betel nuts so that each betel nut can be evenly heated.

[0036] At the same time, the driving motor 33 is started, driving the support shaft 28 to rotate, and the cleaning roller 29 on the outer wall of the support shaft 28 rotates. Since the driving gear 2 30 and the driven gear 2 31 are engaged with each other, the two cleaning rollers 29 rotate in opposite directions at the same time, cleaning both sides of the bottom end of the conveyor belt 26, effectively removing impurities on the conveyor belt 26, ensuring the cleanliness of the equipment and the quality of the betel nut. At the same time, the baffle 34 prevents the impurities after cleaning from splashing over a large area and being difficult to clean. When it is necessary to clean the impurities, the movable door 36 can be opened through the handle 37 to clean the impurities in the collection box 35.
