[0021] 1. There are a tray, a motor and a push rod.

Specific embodiments

[0035] Embodiment 1: In the existing orange conveyor during the discharging process, there is a lack of a buffer and guiding and dispersing structure, resulting in the fruits being prone to collision and damage during the discharging process. To solve this technical problem, the following technical content is disclosed in this embodiment. Please refer to Figures 1-9 as shown; An orange conveyor capable of automatic sorting includes a frame 1 stably placed in the workshop. A conveyor belt 2 is installed on the frame 1, and support frames 3 are uniformly and fixedly installed on the outer side of the conveyor belt 2, and trays 4 are elastically and rotatably connected to the support frames 3; Fixing frames 5 are uniformly and fixedly installed on the outer side of the frame 1, and a discharging structure is installed on the fixing frames 5, and a detection head 8 is fixedly installed on the top of the fixing frames 5. A material guiding frame 9 and a collection box are fixedly installed on the outer side of the frame 1. A buffer plate 12 is elastically lifted and installed on the material guiding frame 9, and through holes are formed in the material guiding frame 9. At the same time, a rotating plate 15 is elastically and rotatably installed in the through holes of the material guiding frame 9; An installation frame 17 is fixedly installed on the material guiding frame 9, and a driving gear 23 is rotatably installed at the middle position of the installation frame 17. A guiding plate 18 for guiding the rolling direction of the oranges is fixedly installed below the driving gear 23. At the same time, a transmission mechanism is provided between the rotating plate 15 and the guiding plate 18.

[0036] The discharging structure includes a motor 6 fixedly installed on the back of the fixed frame 5. The output end of the motor 6 is fixedly installed with a push rod 7. The positions of the fixed frame 5 and the material guiding frame 9 are correspondingly set. During the rotation of the push rod 7, the corresponding tray 4 is pushed to rotate elastically. A first magnet 13 is fixedly installed on one side of the tray 4 close to the buffer plate 12. A second magnet 14 is fixedly installed on the outer side of the upper end of the buffer plate 12. During the rotation of the tray 4, the first magnet 13 on its outer side gradually approaches the second magnet 14. The magnetic poles of the opposite faces of the first magnet 13 and the second magnet 14 are the same.

[0037] A guide post 10 is telescopically connected through the upper end of the material guiding frame 9. A spring 11 is connected between the lower end of the guide post 10 and the material guiding frame 9. The upper end of the guide post 10 is fixedly connected to the lower surface of the buffer plate 12. The lower end of the buffer plate 12 is attached to the upper end of the rotating plate 15. During the downward movement of the buffer plate 12, the rotating plate 15 is pushed to rotate elastically. After rotation, the rotating plate 15 is in a horizontal state. During the rotation and reset process of the rotating plate 15, the oranges falling above it are pushed to roll again.

[0038] The transmission mechanism includes a pull rope 16 wound around the outer side of the shaft part of the rotating plate 15. Two rotating shafts 20 are symmetrically arranged on the mounting frame 17 with respect to the driving gear 23. The two rotating shafts 20 are connected by a belt pulley drive. A transmission wheel 22 is sleeved on the outer side of the left rotating shaft 20. The transmission wheel 22 is elastically rotatably connected above the mounting frame 17. The upper end of the pull rope 16 is wound around the outer side of the transmission wheel 22. When the rotating plate 15 rotates, the transmission wheel 22 is pulled to rotate synchronously through the pull rope 16. A plurality of card slots 2201 are evenly formed on the inner wall of the transmission wheel 22. A plurality of tooth receiving grooves 2001 are evenly formed on the outer wall of the left rotating shaft 20. A clamping tooth 2002 is elastically rotatably arranged inside the tooth receiving groove 2001. During the elastic rotation of the transmission wheel 22, the clamping tooth 2002 is clamped in the card slot 2201 to drive the rotating shaft 20 to rotate synchronously. During the rotation and reset process of the transmission wheel 22, the clamping tooth 2002 is elastically rotated and received in the tooth receiving groove 2001. The lower end of the rotating shaft 20 is fixedly connected with a half gear 21. The two half gears 21 are respectively located on both sides of the driving gear 23. The two half gears 21 and the driving gear 23 are alternately engaged to drive the driving gear 23 to rotate reciprocally. Two inclined plates are arranged on both sides of the guide plate 18. The distance between the two plates on the guide plate 18 gradually decreases from top to bottom. An elastic film 19 is fixedly connected between the upper end of the guide plate 18 and the inner wall of the material guiding frame 9.

[0039] By adopting the above technical solution, the conveyor belt 2 is controlled to transport the support frame 3. When the tray 4 passes under the detection head 8, the detection head 8 can detect the oranges on the tray 4. When the detection data meets the standard, the motor 6 is started, so that the motor 6 drives the push rod 7 at its output end to rotate, so that the push rod 7 can push the tray 4 at the corresponding position to rotate elastically, so as to pour the oranges in the tray 4 towards the buffer plate 12. As the tray 4 rotates, the first magnet 13 on its outer side will approach the second magnet 14 on the buffer plate 12, so that the buffer plate 12 moves elastically downward under the action of magnetic force. The poured oranges can be initially buffered after contacting the buffer plate 12. At the same time, the buffer plate 12 will push the rotating plate 15 to rotate elastically during the downward movement, thereby reducing the initial inclination angle of the rotating plate 15 to reduce the rolling speed of the oranges after buffering. When the rotating plate 15 gradually rotates and resets, the oranges can continue to change from a static state to a rolling state, avoiding stagnation of the oranges and affecting subsequent collection. As the rotating plate 15 rotates, its shaft part will wind up the pull rope 16, so that the other end of the pull rope 16 pulls the transmission wheel 22 to rotate elastically. During the rotation of the transmission wheel 22, the card slot 2201 opened on its inner wall will engage with the tooth 2002, thereby driving the rotating shaft 20 to rotate, so that the half gear 21 on one side meshes with the driving gear 23, and then drives the guide plate 18 to rotate and swing, realizing the adjustment of the rolling direction of the oranges, avoiding the oranges from rolling in the same direction and causing accumulation and impact at one place. When the half gear 21 on one side and the driving gear 23 finish meshing, the half gear 21 on the other side and the driving gear 23 start to mesh, and then drive the driving gear 23 to rotate in the reverse direction, so that the guide plate 18 can reciprocate and intermittently rotate and swing, improving the uniformity of the feeding and collection of the oranges.

[0040] Embodiment 2: The technical content disclosed in this embodiment is a further improvement based on the above Embodiment 1. During the sorting process of the existing orange conveyor, it is inconvenient to assist in cleaning and dissipating heat from the detection equipment, resulting in a decrease in detection accuracy after long-term use. In order to further solve this technical problem, the following technical content is disclosed in this embodiment, as Figures 3-6 shown; a bladder 24 is connected between the upper ends of the buffer plate 12 and the material guide frame 9, and an air delivery pipe 25 is connected to the outer side of the bladder 24, and the pipe orifice of the air delivery pipe 25 faces the detection head 8.

[0041] By adopting the above technical solution, with the reciprocating lifting adjustment of the buffer plate 12, the buffer plate 12 will cooperate with the upper part of the material guide frame 9 to reciprocally squeeze and stretch the bladder 24, so that the bladder 24 can inhale air through the air delivery pipe 25 and blow the inhaled air to the outside of the detection head 8, thereby realizing the automatic cleaning and heat dissipation of the detection head 8, effectively ensuring the working performance of the detection head 8, avoiding detection errors during the conveying process and reducing the sorting efficiency and accuracy, and effectively improving the use effect of the equipment.
