Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-12 The present invention will be described in further detail below.

[0030] This utility model discloses a blueberry sorting machine. (Refer to...) Figure 1 The blueberry sorting machine includes a conveying mechanism 14 for receiving and conveying blueberries; a sorting belt mechanism 15, located at the end of the conveying mechanism 14, for screening impurities; a queuing conveying mechanism 16, located downstream of the sorting belt mechanism 15, for queuing and conveying blueberries individually; a sorting tray mechanism 17 for receiving and selectively releasing blueberries; a vision mechanism 19, located above the sorting tray mechanism 17, for identifying the size of the blueberries, specifically their diameter in this embodiment; and a discharge conveying mechanism 18, located below the sorting tray mechanism 17, for receiving the released blueberries and conveying them to a side collection point. In this embodiment, the discharge conveying mechanism 18 includes multiple conveyor belts, with different belts used to transport blueberries of different diameters.

[0031] Reference Figure 2The queuing conveyor mechanism 16 includes multiple sets of conveyor belt structures 1 driven by the same drive unit 4. Each set of conveyor belt structures 1 includes a first conveyor belt 11 and a second conveyor belt 12 arranged at an angle in the width direction, with the first conveyor belt 11 and the second conveyor belt 12 having the same transmission direction. By driving multiple sets of conveyor belt structures 1 by the same drive unit 4, the number of drive units 4 and control systems is reduced, thus lowering equipment costs. At the same time, the multiple sets of conveyor belt structures 1 achieve mechanical linkage through the same drive unit 4, improving conveying consistency and ensuring that blueberries are queued and conveyed one by one.

[0032] Reference Figure 3 In some embodiments, the queuing conveying mechanism 16 further includes a transmission member 2 and a first transmission part 3. The conveyor belt structure 1 is arranged in multiple groups along the length direction of the transmission member 2. The first transmission part 3 is arranged in multiple groups along the length direction of the transmission member 2. One end of the first conveyor belt 11 and the second conveyor belt 12 are respectively connected to a second transmission part 13. The second transmission part 13 and the first transmission part 3 are in one-to-one transmission cooperation. The output end of the drive member 4 is connected to the transmission member 2.

[0033] In this embodiment, the angle between the first conveyor belt 11 and the second conveyor belt 12 in the width direction is 80-150°. This embodiment limits the angle to 90°, forming a right-angled V-shaped groove between the two conveyor belts. The blueberries are held within this angle, and the synchronous movement of the two conveyor belts propels the blueberries forward, effectively preventing them from rolling to the sides or falling during transport. In other embodiments, any angle between 80° and 150° can be selected according to actual conditions.

[0034] In other embodiments, the angle between the first conveyor belt 11 and the second conveyor belt 12 in the width direction can also be an acute angle to accommodate materials of different particle sizes or shapes.

[0035] Continue to refer to Figure 3 In this embodiment, the ends of the first conveyor belt 11 and the second conveyor belt 12 are staggered, and the second transmission parts 13 are respectively located on both sides of the transmission member 2. The second transmission parts 13 of the first conveyor belt 11 and the second conveyor belt 12 are respectively located on both sides of the transmission member 2, and respectively mesh with their respective first transmission parts 3, optimizing the spatial layout and improving the compactness of the equipment; and the staggered arrangement avoids positional interference between the two second transmission parts 13 on the transmission member 2, further ensuring the reliability of the transmission engagement.

[0036] The first transmission unit 3 and the second transmission unit 13 are meshing helical gears. Helical gear transmission features smooth meshing, high load-bearing capacity, and low transmission noise, improving the stability and reliability of power transmission. Furthermore, the helical gears can adapt to different angles of the first conveyor belt 11 and the second conveyor belt 12 by changing the angle of the helical teeth.

[0037] The driving component 4 includes a motor 41, a driving wheel 42, and a driven wheel 43. The output end of the motor 41 is connected to the driving wheel 42, and the driving wheel 42 meshes with the driven wheel 43. The driven wheel 43 is connected to the end of the transmission component 2. The motor 41 drives the driving wheel 42 to rotate, thereby driving the driven wheel 43 to rotate the transmission component 2. Through the meshing transmission of the driving wheel 42 and the driven wheel 43, the power of the motor 41 is stably transmitted to the transmission component 2. The structure is simple, the transmission efficiency is high, and it is easy to install and maintain.

[0038] Reference Figure 4 In some embodiments, multiple sets of the queuing conveying mechanism 16 are arranged along the conveying direction, and there is a height difference between the multiple sets of the queuing conveying mechanism 16 to form a nested spatial structure, which can facilitate the adjustment of the transmission speed between different sets, and the downstream conveying component is located below the previous conveying component, which facilitates the transmission of blueberries and other blueberries to the next conveying component.

[0039] The conveyor belt structure 1 also includes an anti-drop component 5, which is disposed at the downstream end of the upper queuing conveyor 16 in the adjacent queuing conveyor 16, and below the gap between the first conveyor belt 11 and the second conveyor belt 12 in the same group of the upper queuing conveyor 16. This gap is also the gap between the upper and lower queuing conveyor 16. The anti-drop component 5 fills the gap between the upper and lower queuing conveyor 16 between adjacent conveying components, effectively preventing materials from falling from the gap between layers, reducing material loss, and improving the stability of the conveying process.

[0040] Reference Figure 5 In this embodiment, the conveyor belt structure 1 further includes a connector 6. The connector 6 has inclined mounting surfaces on both sides, and the sides of the first conveyor belt 11 and the second conveyor belt 12 are respectively fitted and installed against the mounting surfaces on both sides. This inclined mounting surface ensures the relative angular accuracy between the two conveyor belts, simplifies the on-site installation and alignment process, and shortens the commissioning cycle.

[0041] Bolt holes 7 are provided on the mounting surface, and mounting holes 8 are provided on the sides of both the first conveyor belt 11 and the second conveyor belt 12. Bolts pass through the mounting holes 8 and are screwed into the bolt holes 7. Two bolt holes 7 are provided at intervals on the same side, and the mounting holes 8 are correspondingly provided with the bolt holes 7. Through the bolt connection, the first conveyor belt 11, the second conveyor belt 12 and the connector 6 are detachably and fixedly connected. The connection is firm and easy to disassemble and maintain, further improving the installation efficiency.

[0042] In some embodiments, a shielding member 9 is provided between two adjacent sets of conveyor belt structures 1. The shielding member 9 is used to shield the gap between the first conveyor belt 11 and the second conveyor belt 12 in the two adjacent sets of conveyor belt structures 1. The shielding member 9 is fixed to the first conveyor belt 11 and the second conveyor belt 12 by screwing. The shielding member 9 has an L-shaped cross-section, and both sides of the shielding member 9 are on the same plane as the conveying surfaces of the first conveyor belt 11 and the second conveyor belt 12, respectively. The shielding member 9 shields the gap between the first conveyor belt 11 and the second conveyor belt 12 in the adjacent conveyor belt structures 1, preventing foreign objects from falling into the gap and improving the overall protection capability of the conveyor line.

[0043] Reference Figure 6 In some embodiments, both the first conveyor belt 11 and the second conveyor belt 12 include a drive roller 111, a drive belt 113, and a drive bracket 112. The drive bracket 112 is installed between the two drive rollers 111, and the drive belt 113 is wound around the two drive rollers 111. The drive roller 111 and the drive bracket 112 are either an integral structure or a separate structure. When the drive roller 111 and the drive bracket 112 are an integral structure, the position of the drive roller 111 relative to the drive bracket 112 is not adjustable. When the drive roller 111 and the drive bracket 112 are separate structures, the position of the drive roller 111 can be adjusted relative to the drive bracket 112 to adjust the tension of the conveyor belt.

[0044] In some embodiments, the conveyor belt structure 1 further includes an adjustment structure 10, which includes an adjustment rod 101 and an adjustment member 102. The adjustment rod 101 is mounted on one of the drive rollers 111 and cooperates with it. Figure 5 Another drive roller 111 can be fixed to the drive bracket 112 by screwing. The adjusting member 102 is installed on the drive bracket 112 and is connected to the adjusting rod 101; when the adjusting member 102 is moved, the adjusting rod 101 drives the drive roller 111 to move, so as to adjust the tension of the conveyor belt.

[0045] Continue to refer to Figure 6 The adjusting element 102 is installed on the transmission bracket 112, and the transmission bracket 112 is equipped with an adjusting ring 103. The adjusting element 102 is screwed to the adjusting ring 103, and the adjusting element 102 is rotatably connected to the adjusting rod 101. When the adjusting element 102 is rotated or moved, the adjusting element 102 drives the adjusting rod 101 to move, and the adjusting rod 101 drives the transmission roller 111 to move and adjust the tension of the transmission belt 113.

[0046] The transmission bracket 112 is also provided with a fixing bolt 104, and the adjusting rod 101 is provided with an adjusting groove 105. The fixing bolt 104 passes through the adjusting groove 105 and is screwed to the transmission bracket 112. When the fixing bolt 104 is tightened, the adjusting rod 101 is fixed to the transmission bracket 112. When the fixing bolt 104 is loosened, the adjusting rod 101 can be moved. The fixing bolt 104 further improves the installation stability of the transmission roller 111.

[0047] Reference Figure 7 In other embodiments, the drive roller 111 and the drive bracket 112 may also be an integral structure or fixed in other ways. The rotating roller 152 is rotatably connected to the drive bracket 112. An integral structure means that the drive roller 111 and the drive bracket 112 cannot move relative to each other to adjust the tension of the drive belt 113.

[0048] Reference Figure 8 In some embodiments, the transmission mechanism 14 includes a conveyor belt 141, a tension roller 142, and a first tension adjustment assembly 143. The conveyor belt 141 is laid along the frame 144 and wound around the tension roller 142. The first tension adjustment assembly 143 includes a sliding seat 431, a fixed seat 432, an adjusting member, and a fixing member. The tension roller 142 is rotatably connected to the sliding seat 431. The sliding seat 431 is fixed to the frame 144 by the fixing member, which is a bolt. The bolt fixes the sliding seat 431 to the frame 144. When the sliding seat 431 needs to be moved, the bolt can be loosened. The fixed seat 432 is screwed onto the frame 144. The adjusting member is installed between the fixed seat 432 and the sliding seat 431. When the fixing member is loosened and the adjusting member is adjusted, the adjusting member drives the sliding seat 431 and the tension roller 142 to translate, thereby changing the tension of the conveyor belt 141. The adjusting component is also a bolt, which is screwed to the fixed seat 432 and rotatably connected to the sliding seat 431. Rotating the adjusting component can drive the sliding seat 431 to change position, thereby changing the tension of the conveyor belt 141. The tension roller 142 connected to the first tension adjusting component 143 is a driven roller, which is located on the side close to the screening belt mechanism 15. It can also be located on the side of the driving roller.

[0049] Reference Figure 9In other embodiments, the transmission mechanism 14 includes a conveyor belt 141, a tension roller 142, and a second tension adjustment assembly 145. The second tension adjustment assembly 145 includes a sliding plate 451, a fastening seat 452, and a fastener 453. The sliding plate 451 is slidably connected to the fastening seat 452. The fastening seat 452 has a sliding groove 454. The two ends of the tension roller 142 of the conveyor belt 141 pass through the sliding grooves 454 on both sides and are rotatably connected to the sliding plate 451 via bearings. The fastener 453 is adjustable to the fastening seat 452, and the other end of the fastener 453 is rotatably connected to the sliding plate 451. The other end of the fastener 453 passes through the sliding plate 451 and can rotate. The two sides are limited by nuts. When the fastener 453 is adjusted, the fastener 453 drives the sliding plate 451 to move and drives the tension roller 142 to move to change the tension of the conveyor belt 141. Fastener 453 is a bolt, screwed onto fastener 452, with one end rotatably connected to sliding plate 451. Rotating the bolt allows sliding plate 451 to move along fastener 452, and sliding groove 454 allows movement of tension roller 142. The tension roller 142 connected to the second tension adjustment assembly 145 is the driving roller, located on the side away from screening belt mechanism 15. It can also be located on the driven roller side.

[0050] Reference Figure 10 In some embodiments, the screening belt mechanism 15 includes a screening belt 151, a rotating roller 152, and a first mounting structure 153. The screening belt 151 is spaced apart and wound around the rotating roller 152. The first mounting structure 153 includes a mounting plate 531 and a connecting plate 532. Both ends of the rotating roller 152 are rotatably mounted to the connecting plate 532. The connecting plate 532 is screwed onto the mounting plate 531. The mounting plate 531 has an L-shaped structure, with one side mounted to the connecting plate 532 and the other side mounted to the support frame 154 of the equipment. The height of the mounting plate 531 is higher than the upper surface of the screening belt 151, which prevents blueberries from falling from both sides. A conveyor belt is provided below the screening belt 151 to transport impurities that fall from the gaps in the screening belt 151 to the side for collection.

[0051] Reference Figure 11In other embodiments, the screening belt mechanism 15 includes a screening belt 151, a rotating roller 152, and a second mounting structure 155. The screening belt 151 is spaced apart and wound around the rotating roller 152. The second mounting structure 155 includes a rotating seat 551 and a limiting plate 552. The rotating seat 551 is screwed onto the frame 144 of the equipment. Both ends of the rotating roller 152 are rotatably mounted on the rotating seat 551. The limiting plate 552 is disposed on both sides of the screening belt 151 perpendicular to the transmission direction. The limiting plate 552 has an L-shaped structure, with a clearance groove on one side, in which the rotating roller 152 is located. The other side is screwed onto the support frame 154. The height of the limiting plate 552 is higher than the height of the upper surface of the screening belt 151, thus preventing blueberries from falling from both sides.

[0052] Reference Figure 12 In this embodiment, the sorting tray mechanism 17 includes a connecting frame 171 and a flip plate 173 hinged to the connecting frame 171, with the flip plate 173 serving as a bearing surface. Divider plates 172 are provided on both sides of the connecting frame 171 in the blueberry entry direction. The divider plates 172 guide and limit the blueberries entering the flip plate 173, preventing them from deviating from the flip plate 173 during transport and ensuring sorting accuracy. Multiple sorting tray mechanisms 17 are arranged side-by-side, with the connecting frames 171 of adjacent sorting tray mechanisms 17 interconnected, enabling synchronous operation of multiple sorting channels and improving sorting efficiency.

[0053] Refer again Figure 1 The vision mechanism 19 can employ an industrial camera, which is mounted via a mounting bracket and equipped with auxiliary lighting. The camera is used to take pictures and obtain the diameter of the blueberries. The vision mechanism 19 is electrically connected to a controller. Based on the recognition results from the vision mechanism 19, the controller controls the tilting plate 173 of the sorting tray mechanism 17 to selectively release blueberries above the conveyor belt of the corresponding feeding conveyor mechanism 18, completing the automatic sorting of blueberries by size. Specifically, the controller can control a motor to drive the tilting plate 173 to tilt. The controller includes an electrical control box, frequency converter, PLC, relays, etc. Through a dedicated PLC program, in conjunction with sensors and vision cameras, the movement state of each component is precisely controlled. The specific control principle is existing technology; this invention only protects the structure itself and does not involve software improvements. The number of industrial cameras is correspondingly set to the width of the conveyor belt structure 1, ensuring that there is one industrial camera on each conveyor line to acquire information.

[0054] The implementation principle of the blueberry sorting machine in this embodiment of the utility model is as follows: by setting the transmission mechanism 14, the sorting belt mechanism 15, the queuing conveyor mechanism 16, the sorting tray mechanism 17 and the unloading conveyor mechanism 18 to be connected in sequence, the functional modules are integrated into an integrated layout, reducing the floor space; at the same time, the queuing conveyor mechanism 16 drives multiple sets of conveyor belt structures 1 through the same driving component 4, making the overall equipment more compact and saving equipment costs.

[0055] The above are exemplary embodiments disclosed in this utility model.
