[0002] As people pursue a higher quality of life, more and more people are demanding higher quality fruits and vegetables, making fruit and vegetable sorting an important technology.

[0003] In automated fruit and vegetable sorting, fruits and vegetables are stored in fruit cups, which are conveyed along guide rails by a conveyor. Once the cups reach a designated position, an air-blowing sorting device blows air into the cups, causing the fruits and vegetables to fall out. The air-blowing sorting device includes a frame, an air-blowing assembly, and a blocking assembly. The air-blowing assembly is located within the frame assembly, and air outlets are provided on the side walls of the frame assembly. The air-blowing assembly blows air into these outlets. The blocking assembly is located along the air-blowing path of the air-blowing assembly. When the fruits and vegetables in the cups reach the air outlets, the air-blowing assembly blows air into them, causing them to detach from the cups. The blocking assembly cushions the fruits and vegetables, allowing them to fall into the conveyor for transport to the packaging area. The barrier assembly includes a flexible barrier component and a suspension frame. Generally, to improve the installation efficiency of the barrier assembly, the frame component has mounting holes, and one end of the suspension frame extends into the mounting holes for quick installation. The flexible barrier component is installed on the suspension frame and is located in the path of the fruit and vegetables to buffer and block them, so as to prevent damage to the fruit and vegetable peels.

[0004] However, because the flexible barrier is located on the air blowing path, and the area of ​​the flexible barrier on the air blowing path is large, it is strongly affected by the wind. In addition, the mounting holes of the suspension frame are not stable enough, which may cause the flexible barrier to be affected by the wind, resulting in the suspension frame loosening or detaching from the frame.
