[0037] An embodiment of the present application provides a conveying mechanism 100, which comprises an input transmission assembly 10, a transition transmission assembly 20 and an output transmission assembly 30.

The first output end 12 is located above the second input end 21, and the first output end 12 partially overlaps the second input end 21. The transmission direction of the output transmission assembly 30 forms a predetermined angle with the transmission direction of the input transmission assembly 10.

The output transmission assembly 30 comprises a third input end 31 and a third output end 32. The third input end 31 is in communication with the second output end 22.

[0038] Here, it should be noted that the fruits and vegetables move along the direction of the input transmission assembly 10, the transition transmission assembly 20 and the output transmission assembly 30. The fruits and vegetables pass through the first input end 11, the first output end 12, the second input end 21, the second output end 22, the third input end 31 and the third output end 32 in sequence, and then are conveyed to a sorting module for sorting.

[0039] Specifically, the transmission direction of the input transmission assembly 10 forms a predetermined angle with the transmission direction of the output transmission assembly 30, so that the overall conveying mechanism 100 turns at the joint of the input transmission assembly 10 and the transition transmission assembly 20, avoiding the overall conveying mechanism 100 being in a straight line type and being structurally redundant.

[0043] Specifically, any one of the input units 13 can convey fruits and vegetables, and at the first output end 12, the ends of the plurality of input units 13 are arranged in a stepped manner, so that the fruits and vegetables can be evenly distributed when falling from the input conveying assembly 10 to the transition conveying assembly 20, avoiding too many fruits and vegetables falling on one place of the transition conveying assembly 20, and reducing the blockage of the fruits and vegetables on the transition conveying assembly 20.

[0044] In one embodiment, each input unit 13 comprises a plurality of first conveying belts 131, and the plurality of first conveying belts 131 are distributed along a direction perpendicular to the conveying direction of the input conveying assembly 10.

Moreover, in each input unit 13, the lengths of all the first conveying belts 131 are consistent, so that the conveying surface of each input unit 13 for supporting and conveying fruits and vegetables is substantially rectangular, and the fruits and vegetables conveyed by the plurality of first conveying belts 131 in each input unit 13 can fall from the first output end 12 to a position of the second input end 21 in a straight line along the conveying direction of the output conveying assembly 30.

[0049] Specifically, when the input unit 13 conveys the fruits and vegetables away from the first output end 12, the fruits and vegetables with speed will hit the flexible blocking piece 60, the flexible blocking piece 60 blocks the fruits and vegetables, and the fruits and vegetables fall into the transition conveying assembly 20 from the gap 70, avoiding the fruits and vegetables falling from the first output end 12 to separate from the transition conveying assembly 20 due to too fast movement speed. In addition, the lengths of the plurality of input units 13 are different, and the fruits and vegetables conveyed by different input units 13 will uniformly fall onto the transition conveying assembly 20, avoiding the fruits and vegetables being blocked in the gap 70 to cause the conveying efficiency to decrease.

[0050] In addition, the flexible blocking piece 60 is hung in a manner, facilitating the installation and disassembly of the flexible blocking piece 60.

[0051] In one embodiment, the flexible blocking piece 60 is provided with a plurality of output channels 33, and each gap 70 between the flexible blocking piece 60 and the first output end 12 of the corresponding one input unit 13 is opposite to one corresponding output channel 33.

Moreover, the fruits and vegetables conveyed from one input unit 13 fall into the gap 70 and are conveyed by the transition conveying assembly 20 to one corresponding output channel 33 for transportation, improving the conveying efficiency of the output conveying assembly 30 and reducing the collision of the fruits and vegetables conveyed by different input units 13 on the transition conveying assembly 20.

[0053] In one embodiment, the flexible blocking piece 60 comprises a base 61 and a flexible blocking strip 62, the base 61 is connected to the mounting rack 50, the flexible blocking strip 62 is provided with a plurality of flexible blocking strips 62, the plurality of flexible blocking strips 62 are arranged side by side on one side of the base 61 away from the mounting rack 50, and each flexible blocking piece 60 extends from the base 61 to the transition conveying assembly 20.

[0054] Specifically, the plurality of flexible blocking strips 62 are arranged in parallel and connected to the base 61, and the strip shape is more prone to deformation than the plate shape. After the fruits and vegetables collide with the flexible blocking strips 62, the fruits and vegetables are not easy to cause damage to the surface of the fruits and vegetables, thereby protecting the integrity of the surface of the fruits and vegetables. The plurality of flexible blocking strips 62 are arranged side by side to cover the end of the base 61, thereby improving the blocking effect of the flexible blocking member 60. The flexible blocking strips 62 are made of flexible materials, such as plastic, rubber, etc.

[0055] In one embodiment, the transition transmission assembly 20 includes a second driving member 23 and a second conveying belt 24, the second driving member 23 is connected to the second conveying belt 24, and the second driving member 23 is used to drive the second conveying belt 24 to move; the conveying direction of the second conveying belt 24 is the same as the transmission direction of the output transmission assembly 30.

The purpose of this arrangement is to prevent the fruits and vegetables from being blocked due to the long stay time of the fruits and vegetables on the transition transmission assembly 20. Moreover, it is not necessary to additionally set up a corresponding carrier to transport the fruits and vegetables, and the structure is simple and the production cost is low.

[0057] In one embodiment, the predetermined included angle between the transmission direction of the output transmission assembly 30 and the transmission direction of the input transmission assembly 10 is 90°, the output transmission assembly 30 includes a plurality of conveying units 34, the plurality of conveying units 34 are arranged in a stepped manner along the transmission direction of the output transmission assembly 30 and gradually decrease in height; each conveying unit 34 includes a plurality of conveying members 341, the plurality of conveying members 341 are arranged in sequence along a direction perpendicular to the transmission direction of the output transmission assembly 30.

The purpose of this arrangement is that the fruits and vegetables conveyed from the input transmission assembly 10 do not have the speed of the transmission direction of the transition transmission assembly 20 when entering the transition transmission assembly 20; specifically, the fruits and vegetables have the speed along the transmission direction of the input transmission assembly 10 and the speed decreases after colliding with the flexible blocking strips 62, thereby preventing the transportation route of the fruits and vegetables on the transition transmission assembly 20 from having an inclined included angle with the transmission direction of the transition transmission assembly 20, and further ensuring that the fruits and vegetables separated from one input unit 13 can enter the corresponding output channel 33.
