Single-chain double-supported fruit cup device for sorting fruits and vegetables

A single-chain double-supported fruit cup device for sorting fruits and vegetables, comprising:

• a single-chain double-supported fruit cup which is provided on a conveyor track;
• wherein the single-chain double-supported fruit cup comprises:
• a fruit cup support frame (1),
• two hoods (2, 2′),
• two internal liner (3, 3′),
• two trays (4, 4′),
• two pallets (5, 5′), and
• two inverted L-shaped pallets (13, 13′);
• wherein the two pallets (5, 5′) are rotationally symmetrically hinged on both sides of the cup support frame (1) based on two side pivots (10, 10′), two first side torsion spring (11, 11′) and two second side torsion spring (12, 12′) are set on the two side pivots (10, 10′) and providing torque to the two pallets (5, 5′), two trays (4, 4′) are provided on the two pallets (5, 5′), and the two hoods (2, 2′) are mounted on two trays (4, 4′) for placing spherical fruits;
• the two inverted L-shaped pallets (13, 13′) are rotationally symmetrically hinged on the fruit cup support frame (1) by the intermediate shaft (14), and the two inverted L-shaped pallets (13, 13′-) extend towards the two pallets (5, 5′) on both sides and are cooperatedly connected, two medium torsion spring (15, 15′) are set on the intermediate shaft (14) providing torque to the two inverted L-shaped pallets (13, 13′).
