Description

Technical Field

[0001] This invention relates to the field of fruit sorting technology, specifically a multifunctional dual-channel pear sorting machine. Background Technology

[0002] A fruit sorting machine is a device used for sorting and classifying fruits. It can sort various fruits such as apples, pears, and citrus fruits, and is usually used in orchards or fruit processing plants. A multi-functional dual-channel fruit sorting machine can process two different sizes or varieties of fruits simultaneously, improving production efficiency. A multi-functional dual-channel apple sorting machine may also have other functions, such as washing, impurity removal, and packaging, making it a multi-functional fruit processing equipment. However, current multi-functional dual-channel fruit sorting machines have limitations during the sorting process. Because the peels of fruits such as apples and pears are relatively fragile, these fruits are easily damaged during sorting, resulting in poor product quality and unnecessary losses. Moreover, after washing, the fruit surface will have a lot of moisture, which increases the risk of fruit rotting.

[0003] An investigation revealed that a Chinese patent discloses a multifunctional dual-channel apple sorting machine (publication number: CN221790154U), which includes a sorting box. The top and front sides of the sorting box are fixedly connected to fixed plates. A sorting rack is fixedly connected to the bottom of the adjacent side of the two fixed plates. A second collection box is fixedly connected to the lower right side of the sorting box. A first collection box is fixedly connected to the right side of the second collection box. A buffer plate is slidably connected to the middle of the inner wall of the sorting box. A diversion plate is fixedly connected between the top of the second collection box and the first collection box.

[0004] While the aforementioned patent achieves initial water absorption by setting up absorbent towels, activating a fan to blow air through ducts and distribution pipes, and then using a roller conveyor and transfer rollers to transport apples from left to right, effectively ensuring that the apples' surface is dry, round fruits such as apples and pears tend to rotate relative to the transmission rollers during transport, causing the fruit to spin between the two rollers and affecting transport efficiency. Furthermore, during the large-scale fruit sorting process, sorted fruits will fall onto the conveyor belt and be directly transported to the packaging area for packaging. Although traditional conveyor belts can provide some cushioning through deformation when impacted by fruit, the cushioning effect of conveyor belt deformation alone is limited for fruits with thin skins, such as pears, and is insufficient to meet practical needs.

[0005] Therefore, the present invention provides a multifunctional dual-channel pear sorting machine to solve the above problems. Summary of the Invention

[0009] As a preferred technical solution of this application, a guide plate is fixedly connected between the frame and the support frame, fixed plates are symmetrically fixed on the side wall of the support frame, a connecting plate is fixedly connected between the fixed plates, and a movable groove is provided between the connecting plate and the fixed plate. The shaft of the water absorption roller is movably connected in the movable groove. An installation rod is provided on the support frame, and both ends of the installation rod are rotatably connected to the fixed plate. The installation rod is coaxially fixed with the sprocket.

[0010] As a preferred technical solution of this application, a mounting block is fixedly connected to the support frame, a fan blade is rotatably connected to one side of the mounting block, and a driven wheel is rotatably connected to the other side of the mounting block. The fan blade is coaxially fixed to the driven wheel through a connecting shaft.

[0011] As a preferred technical solution of this application, a drive wheel is rotatably connected to the fixed plate, and the drive wheel meshes with the driven wheel. The drive wheel is coaxially fixed with the mounting rod.

[0012] As a preferred technical solution of this application, two second pulleys are provided between the support frame and the machine frame, and a second transmission belt is connected between the two second pulleys. One of the second pulleys is coaxially fixed with the drive pulley, and the other second pulley is rotatably connected to the machine frame and coaxially fixed with the drive roller.

[0013] As a preferred technical solution of this application, a fixing block is fixedly connected to the side wall of the frame, and a rotating rod is rotatably connected between the fixing block and the mounting frame.

[0017] (III) Beneficial Effects 1. By setting up the coordinated operation between the sprocket, chain, gear ring, and spur gear, the water-absorbing roller is driven to rotate while being circulated and conveyed. The rotating water-absorbing roller is connected to the chain, which drives the water-absorbing roller to circulate and convey. During this process, the spur gear, which is fixed coaxially with the water-absorbing roller, rolls on the gear ring, thereby driving the water-absorbing roller to rotate. This causes the pears between the water-absorbing rollers to rotate, fully absorbing the water from the pears. The circulating water-absorbing roller conveys the pears to the guide plate, avoiding the situation where the pears continuously rotate on the water-absorbing roller and cannot be conveyed smoothly.

[0018] 2. By setting up the coordinated operation between the mounting ring, rollers, dampers and springs, the conveyor belt can effectively buffer when impacted by pears. When the sorted pears fall onto the conveyor belt, the pears impact and squeeze the conveyor belt due to their own weight. The conveyor belt drives the rollers to stretch the springs through the limit strips. With the help of the springs' buffering effect, the impact force of the falling pears is effectively reduced, thereby avoiding damage to the pear skin. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] This invention provides a multifunctional dual-channel pear sorting machine, such as... Figures 1-9As shown, the technical solution includes a frame 1, a sorting machine body 2, and multiple fruit trays 14. The sorting machine body 2 is fixedly mounted on the frame 1. Two drive rollers 11 are rotatably connected inside the frame 1, and the multiple fruit trays 14 are drivenly connected to the two drive rollers 11. It should be noted that a drive belt is driven between the two drive rollers 11, and multiple mounting seats are fixedly mounted on the drive belt. The fruit trays 14 are rotatably connected to the mounting seats and can deflect to both sides of the frame 1. After the sorting machine body 2 sorts out the fruit, the fruit trays 14 on the drive mounting seats rotate to both sides, and the pears on the fruit trays 14 can fall onto the conveyor belt 5. The use of the sorting machine body 2 and the fruit trays 14 are existing technologies in existing devices and will not be elaborated on here. Multiple mounting frames 3 are fixedly connected to the frame 1. The mounting frame 3 is symmetrically fixed with baffles 4. The mounting frame 3 is equipped with a conveyor belt 5. A buffer mechanism is provided between the conveyor belt 5 and the mounting frame 3. The buffer mechanism includes a spline shaft 12, two mounting rings 16, a roller 17, multiple dampers 18 and springs 19. The spline shaft 12 is rotatably connected to the mounting frame 3. The mounting rings 16 are rotatably connected to the mounting frame 3. The spline shaft 12 passes through the roller 17 and slides coaxially with the roller 17. The dampers 18 are fixedly connected between the mounting rings 16 and the roller 17. When the sorted pears fall onto the conveyor belt 5, the pears impact and squeeze the conveyor belt 5 due to their own weight. The conveyor belt 5 drives the roller 17 to stretch the springs 19. With the buffering effect of the springs 19, the impact force of the falling pears is effectively reduced, thereby avoiding damage to the pear skin. A support frame 7 is provided on one side of the frame 1. Multiple water-absorbing rollers 20 are provided on the support frame 7. A linkage mechanism is symmetrically provided between the water-absorbing rollers 20 and the support frame 7. The linkage mechanism includes a chain 23, a toothed ring 25, two sprockets 22 and multiple spur gears 24. The spur gears 24 are coaxially fixed to the end of the water-absorbing rollers 20. The toothed ring 25 is fixedly connected to the support frame 7 and meshes with the toothed ring 25. The chain 23 is driven between the two sprockets 22. The water-absorbing rollers 20 are rotatably connected to the chain 23. The chain 23 drives the water-absorbing rollers 20 to circulate and convey water. During this process, the spur gears 24, which are coaxially fixed to the water-absorbing rollers 20, roll on the toothed ring 25, thereby driving the water-absorbing rollers 20 to rotate. This causes the pears between the water-absorbing rollers 20 to rotate, fully absorbing the water from the pears. The circulating water-absorbing rollers 20 convey the pears to the guide plate 10, avoiding the situation where the pears continuously rotate on the water-absorbing rollers 20 and cannot be conveyed smoothly.

[0023] Reference Figure 3 and Figure 6 As shown, multiple spline shafts 12 are coaxially fixed together by mounting shafts 15. Springs 19 are sleeved on dampers 18, and the two ends of springs 19 are fixedly connected to mounting rings 16 and rollers 17 respectively. Limiting strips 37 are symmetrically fixed on both sides of the conveyor belt 5, and the limiting strips 37 abut against the side walls of rollers 17. The conveyor belt 5 is driven between rollers 17. When in use, the pears sorted by the sorting machine body 2 fall onto the conveyor belt 5. Due to their own weight, the pears impact and squeeze the conveyor belt 5. The conveyor belt 5 drives the rollers 17 to move closer to each other through the limit bar 37 and stretches the spring 19. With the buffering effect of the spring 19, the impact force of the falling pears is effectively reduced, and the pear skin is prevented from being damaged. The damper 18 dissipates the vibration energy through the damping force and prevents the continuous shaking caused by the rebound of the spring 19.

[0024] Reference Figure 4 As shown, a guide plate 10 is fixedly connected between the frame 1 and the support frame 7. Fixed plates 9 are symmetrically fixed on the side wall of the support frame 7. A connecting plate 8 is fixedly connected between the fixed plates 9. A movable groove is provided between the connecting plate 8 and the fixed plate 9. The shaft of the water suction roller 20 is movably connected in the movable groove. An installation rod 21 is provided on the support frame 7. Both ends of the installation rod 21 are rotatably connected to the fixed plate 9. The installation rod 21 is coaxially fixed with the sprocket 22. When in use, rotating the mounting rod 21 causes the mounting rod 21 to drive the water-absorbing roller 20 on the chain 23 to circulate and transport the water. During the circulation of the water-absorbing roller 20, the spur gear 24 at the end of the water-absorbing roller 20 rotates on the gear ring 25, thereby driving the water-absorbing roller 20 to rotate, causing the pears between the water-absorbing rollers 20 to rotate and fully absorb the water from the pears. The circulating water-absorbing roller 20 transports the pears onto the guide plate 10, and the pears fall onto the circulating fruit tray 14 after passing through the guide plate 10.

[0025] Reference Figure 4 and Figure 8 As shown, a mounting block is fixedly connected to the support frame 7. A fan blade 26 is rotatably connected to one side of the mounting block, and a driven wheel 30 is rotatably connected to the other side of the mounting block. The fan blade 26 is coaxially fixed to the driven wheel 30 through a connecting shaft. A driving wheel 29 is rotatably connected to the fixing plate 9, and the driving wheel 29 meshes with the driven wheel 30. The driving wheel 29 is coaxially fixed to the mounting rod 21. When in use, rotating the mounting rod 21 drives the driving wheel 29 to rotate, which in turn drives the meshing driven wheel 30 to rotate. The driven wheel 30 drives the fan blade 26 to rotate via the connecting shaft. The driving wheel 29 and the driven wheel 30 have different gear ratios. Normal rotation of the driving wheel 29 can drive the driven wheel 30 to rotate quickly, increasing the rotation speed of the fan blade 26 and strengthening the wind force. This can dry the remaining moisture on the pear and effectively remove the moisture from the pear's surface.

[0026] Reference Figure 5 , Figure 6 and Figure 9As shown, two second pulleys 35 are provided between the support frame 7 and the frame 1, and a second transmission belt 36 is connected between the two second pulleys 35. One second pulley 35 is coaxially fixed to the drive pulley 29, and the other second pulley 35 is rotatably connected to the frame 1 and coaxially fixed to the drive roller 11. A fixing block 32 is fixedly connected to the side wall of the frame 1, and a rotating rod 13 is rotatably connected between the fixing block 32 and the mounting frame 3. A first bevel gear 33 is coaxially fixed to the end of the rotating rod 13 away from the mounting frame 3. A second bevel gear 34 is connected to the side wall of the frame 1, and the second bevel gear 34 is coaxially fixed to the second pulley 35. The bevel gear 33 meshes with the second bevel gear 34. Two first pulleys 27 are rotatably connected to the side wall of the mounting frame 3, and a first transmission belt 28 is connected between the two first pulleys 27. One of the first pulleys 27 is coaxially fixed with the rotating rod 13, and the other first pulley 27 is coaxially fixed with the spline shaft 12. A motor 6 is fixedly connected to the side wall of the frame 1, and the output end of the motor 6 is coaxially fixed with the drive roller 11. The outer surface of the water absorption roller 20 is covered with a sponge pad 31, and the ends of the sponge pad 31 are attached by Velcro. The sponge pad 31 absorbs the moisture on the surface of the pear. With the help of Velcro, the sponge pad 31 can be quickly replaced. When in use, the starting motor 6 drives the drive roller 11 to rotate, causing the fruit tray 14 to circulate and transport the pears on the fruit tray 14 through the sorting machine body 2. The drive roller 11 drives the mounting rod 21 to rotate through the second pulley 35 and the second transmission belt 36. At the same time, the rotating second pulley 35 drives the rotating rod 13 to rotate through the meshing first bevel gear 33 and second bevel gear 34. The rotating rod 13 drives the spline shaft 12 to rotate through the first pulley 27 and the first transmission belt 28. The spline shaft 12 drives the coaxial sliding roller 17 to rotate, which in turn drives the conveyor belt 5 to transport the pears. It should be noted that the motor 6 is connected to an external power source via wires. The external power source includes a battery for providing power to the motor 6 and a control switch for controlling its start and stop. The external power source is existing technology. The specific model and specifications of the motor 6 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts existing technology in this field, so it will not be described in detail.

[0027] In summary: During operation, the starting motor 6 drives the drive roller 11 to rotate, causing the fruit tray 14 to circulate and transport the fruit. The drive roller 11 drives the mounting rod 21 to rotate via the second pulley 35 and the second transmission belt 36. The mounting rod 21 drives the water-absorbing roller 20 on the chain 23 to circulate and transport the fruit. At the same time, the mounting rod 21 drives the driven wheel 30 to rotate via the driving wheel 29. The rotating driven wheel 30 drives the fan blade 26 to rotate via the connecting shaft. During the circulating transport of the water-absorbing roller 20, the rotation of the spur gear 24 at the end of the water-absorbing roller 20 on the gear ring 25 drives the water-absorbing roller 20 to rotate, causing the pears between the water-absorbing rollers 20 to rotate and fully absorb the water from the pears. The circulating water-absorbing roller 20 transports the pears onto the guide plate 10, and the pears fall onto the circulating fruit tray 14 after passing through the guide plate 10. During this process, the rotating second pulley 35 drives the rotating rod 13 to rotate through the meshing first bevel gear 33 and second bevel gear 34. The rotating rod 13 drives the spline shaft 12 to rotate through the first pulley 27 and the first transmission belt 28. The spline shaft 12 drives the coaxial sliding roller 17 to rotate, thereby driving the conveyor belt 5 to convey. Meanwhile, the pears on the fruit tray 14 are sorted by the sorting machine body 2 and fall onto the conveyor belt 5. Due to their own weight, the pears impact and squeeze the conveyor belt 5. The conveyor belt 5 drives the rollers 17 to move closer to each other through the limit bar 37 and stretches the spring 19. With the buffering effect of the spring 19, the impact force of the falling pears is effectively reduced, and the pear skin is prevented from being damaged. The damper 18 dissipates the vibration energy through the damping force and prevents the continuous shaking caused by the rebound of the spring 19.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
