Description

Technical Field

[0001] This utility model relates to the field of fruit sorting technology, and in particular to an automatic apple sorting mechanism. Background Technology

[0002] To meet market demand, improve apple quality and value, reduce grading costs, and better reflect apple quality levels, apples undergo sorting. Apple sorting refers to the process of classifying and selecting harvested apples according to certain standards. This not only enhances the market competitiveness of apples but also brings better economic benefits to fruit growers and businesses.

[0003] Chinese Patent CN220590781U discloses an anti-collision automatic apple sorting device, including a placement hopper and a screening frame. A parallel plate is installed on one side of the placement hopper, and multiple infrared sensors of varying heights are connected to the top of one side of the parallel plate. A flat plate is connected to the bottom of the placement hopper, and a pressure assembly is connected to the bottom of the flat plate. The pressure assembly is connected to a flap, and a shaft hole is formed in the side wall of the flap, with a pin connected to the inner wall of the shaft hole. This device, through the use of infrared sensors and compression springs, allows for varying degrees of compression of the springs according to different weights, causing the piston rod to descend by different lengths. The infrared sensors at different heights then push apples of different weights into the screening frame, facilitating more precise sorting of apples of different shapes. Simultaneously, the inclusion of a buffer plate and a rotating shaft prevents rolling or falling apples from colliding and damaging other apples or the machine, ensuring the safe transport of sorted apples.

[0004] However, the above technical solution has the following shortcomings: the device only sets a buffer plate at the bottom of the screening frame to prevent apples from colliding. When apples fall from the inclined placement hopper, they may be damaged by collision. Moreover, when the apples roll and slide to the buffer plate, their kinetic energy is already large. The simple buffer plate is difficult to provide a good cushioning effect for the apples, which reduces the quality of apple sorting and transportation. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an automatic apple sorting mechanism that can effectively buffer and prevent collisions when apples roll on the sorting track, ensuring the integrity of apples during sorting and transfer, and improving the overall quality of apple production.

[0006] The present invention provides an automatic apple sorting mechanism, comprising a conveyor belt and an anti-collision mechanism. The conveyor belt has multiple linearly distributed bases, each with a placement mechanism. The placement mechanism includes a placement frame and a guide frame on the placement frame. The anti-collision mechanism includes a conveyor frame on the side of the conveyor belt, multiple partitions on the conveyor frame, a buffer section on the top of the conveyor frame, and multiple buffer assemblies on the partitions. The buffer section has a smooth surface with uneven portions. Each buffer assembly includes a rotating plate rotatably connected to the partition, three sliding rods penetrating and slidably connected to the rotating plate, a connecting plate on the sliding rods, a sponge pad on the connecting plate, and second telescopic springs with their ends respectively on the connecting plate and the rotating plate.

[0007] Preferably, the placement mechanism further includes an upright plate on the base, a rotating shaft rotatably connected to the upright plate, a spring on the rotating shaft, a mounting plate on the rotating shaft, a fixed cylinder on the mounting plate, a support column slidably connected to the fixed cylinder, a top plate and a bottom plate respectively disposed at both ends of the support column, and a first telescopic spring sleeved on the support column, with the placement frame disposed on the top plate.

[0008] Preferably, the support column is provided with four guide blocks arranged in a circular array, and the guide blocks are slidably connected to the fixed cylinder.

[0009] Preferably, a limit ring is coaxially provided on the rotating shaft, and the limit ring and the upright plate are in close contact with each other.

[0010] Preferably, a side seat is provided on the side of the conveyor belt, and a detection component is provided on the side seat. The detection component includes four columns with increasing height, a sensor provided on the columns, and an indicator rod provided on the base plate. An opening is provided between the mounting plate and the fixed cylinder.

[0011] Preferably, a pushing assembly is provided on the side seat. The pushing assembly includes multiple electric push rods provided on the side seat, a top ball driven and connected to the electric push rods, and an abutment plate provided on the mounting plate. The abutment plate is provided with a groove for the top ball to slide.

[0012] Preferably, a raised ring is coaxially provided on the slide rod.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] This invention features a guide frame that connects to the top buffer section of the conveyor frame, preventing apples from falling directly from the placement frame onto the conveyor frame and causing damage. The concave-convex structure of the buffer section reduces the rate at which the apples gain kinetic energy. Combined with buffer components on each sorting lane, this effectively cushions the rolling apples, allowing them to slowly leave the conveyor frame. This ensures the apples remain intact during sorting and transfer, improving the overall quality of the apple output and demonstrating excellent practicality. Attached Figure Description

[0021] Example 1

[0022] like Figures 1-5 As shown, the automatic apple sorting mechanism proposed in this embodiment includes a conveyor belt 1 and an anti-collision mechanism; multiple linearly distributed bases 2 are provided on the conveyor belt 1, and a placement mechanism is provided on the base 2. The placement mechanism includes a placement frame 11 and a guide frame 12 provided on the placement frame 11.

[0023] The anti-collision mechanism includes a conveyor frame 24 disposed on the side of the conveyor belt 1, multiple partitions 25 disposed on the conveyor frame 24, a buffer part 26 disposed on the top of the conveyor frame 24, and multiple buffer components disposed on the partitions 25. The buffer part 26 has a smooth surface with concave and convex portions. The buffer components include a rotating plate 27 rotatably connected to the partitions 25, three sliding rods 28 that pass through and are slidably connected to the rotating plate 27, a connecting plate 29 disposed on the sliding rods 28, a sponge pad 30 disposed on the connecting plate 29, and a second telescopic spring 31 disposed at both ends on the connecting plate 29 and the rotating plate 27 respectively. A convex ring 32 is coaxially disposed on the sliding rod 28 to prevent the sliding rod 28 from slipping off the rotating plate 27.

[0024] In this embodiment, when the apple is conveyed to the sorting position that meets its specifications by the conveyor belt 1, the placement frame 11 tilts until the guide frame 12 on the placement frame 11 aligns with the top of the conveyor frame 24. The apple rolls down along the groove on the guide frame 12 onto the conveyor frame 24, avoiding the disadvantage of the apple falling directly from the placement frame 11 onto the conveyor frame 24 and causing damage. Then the apple continues to roll down along the buffer part 26. The structural design of the buffer part 26 can reduce the rate of increase of the apple's kinetic energy. And when the apple touches the sponge pad 30, the sponge pad 30... It absorbs some of the apple's kinetic energy. At the same time, the sponge pad 30 and the connecting plate 29 push the slide bar 28 to compress the second telescopic spring 31, further absorbing the apple's kinetic energy. Under the apple's own gravity, it pushes the turntable 27 to rotate, allowing the apple to pass through the first buffer assembly. As the apple continues to roll down, it will contact the second buffer assembly to apply the same buffering effect to the apple. Until the apple leaves the conveyor rack 24, the rolling speed will be very slow, thus ensuring the integrity of the apple during sorting and transfer, improving the overall quality of the apple output, and having good practicality.

[0025] Example 2

[0026] like Figure 2 and Figure 3 As shown, the automatic apple sorting mechanism proposed in this embodiment, compared with the first embodiment, includes a placement mechanism that further includes a vertical plate 3 on the base 2, a rotating shaft 4 rotatably connected to the vertical plate 3, a spring 6 on the rotating shaft 4, a mounting plate 5 on the rotating shaft 4, a fixed cylinder 8 on the mounting plate 5, a support column 9 slidably connected to the fixed cylinder 8, a top plate 10 and a bottom plate 13 respectively on both ends of the support column 9, and a first telescopic spring 15 sleeved on the support column 9. The placement frame 11 is placed on the top plate 10.

[0027] Four guide blocks 16 arranged in a ring array are provided on the support column 9. The guide blocks 16 are slidably connected to the fixed cylinder 8. A limit ring 7 is coaxially provided on the rotating shaft 4. The limit ring 7 and the upright plate 3 are in contact with each other. The limit ring 7 is used to install the rotating shaft 4 on the upright plate 3.

[0028] In this embodiment, the placement frame 11 is used to hold apples. When the apples are placed, they generate downward pressure, which causes the top plate 10 to drive the support column 9 to slide downward. The guide block 16 guides the sliding of the support column 9, preventing the support column 9 from swaying and becoming unstable. The apples remain stable until the elastic force generated by the first telescopic spring 15 is further compressed and equals the weight of the apples. At this time, the bottom plate 13 drives the indicator rod 14 to descend to a certain height, and then the apples are transported by the conveyor belt 1.

[0029] Example 3

[0030] like Figures 1-3 As shown in the figure, the automatic apple sorting mechanism proposed in this embodiment, compared with the second embodiment, has a side seat 17 on the side of the conveyor belt 1, and a detection component on the side seat 17. The detection component includes four columns 18 with increasing height, a sensor 19 on the column 18, and an indicator rod 14 on the base plate 13. An opening is provided between the mounting plate 5 and the fixed cylinder 8, which allows the indicator rod 14 located inside the fixed cylinder 8 to be exposed.

[0031] A pushing assembly is provided on the side seat 17. The pushing assembly includes multiple electric push rods 21 provided on the side seat 17, a top ball 22 driven and connected to the electric push rods 21, and an abutment plate 20 provided on the mounting plate 5. The abutment plate 20 is provided with a sliding groove 23 for the top ball 22 to slide.

[0032] In this embodiment, as each apple moves with the conveyor belt 1, the infrared light emitted by the infrared sensor 19 on one of the columns 18 is blocked by the indicator rod 14. At this time, the sensor 19 sends a signal to the processor (not shown). The processor sends a signal to control the electric push rod 21 to extend, so that the top ball 22 abuts against the slide 23 and continues to rise with the drive of the electric push rod 21. Then the top ball 22 pushes the abutment plate 20 upward, and the abutment plate 20 flips the mounting plate 5. The placement frame 11 is tilted so that the apples can roll down from the guide frame 12 to realize the sorting operation of the apples. Finally, the mounting plate 5 and the rotating shaft 4 return to their initial state under the action of the spring 6 for subsequent use.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
