When the fruit stalk 141 is stuck on the corresponding rotating shaft, it is rolled by the rotating shaft, changing the direction of the fruit on the rotating shaft, and the fruit falls down in order from small to large according to the fruit diameter for screening.

When the fruit contacts the smooth surface, it can accelerate downward movement. When it contacts the rough surface, it can increase the friction on the fruit and promote the rolling of the fruit.

[0049] The sorting unit 7 further includes a first universal coupling 701, a second universal coupling 702, a third universal coupling 703 and a fourth universal coupling 704. One end of the first universal coupling 701 is fixedly connected to the rear end of the first rotating shaft 71, and the other end is coaxially fixed with a first sprocket; one end of the second universal coupling 702 is fixedly connected to the rear end of the second rotating shaft 72, and the other end is coaxially fixed with a second sprocket; one end of the third universal coupling 703 is fixedly connected to the rear end of the third rotating shaft 73, and the other end is coaxially fixed with a third sprocket; one end of the fourth universal coupling 704 is fixedly connected to the rear end of the fourth rotating shaft 74, and the other end is coaxially fixed with a fourth sprocket; a fifth sprocket is fixed to the rear end of the intermediate shaft 13;

[0051] The angle of the rotating shaft is changed by a coupling, and the first rotating shaft 71, the second rotating shaft 72, the third rotating shaft 73, the fourth rotating shaft 74 and the intermediate shaft 13 are controlled by a sprocket to keep the rotation direction and speed consistent.

[0052] It also includes a hopper 11 fixed to the top of the frame 1, and the front of the hopper 11 is connected to a feed chute plate 12 with a notch facing upward, the feed chute plate 12 is installed on the hopper 11, the bottom end of the hopper 11 is connected to the rear end of the feed chute plate 12, the feed chute plate 12 is located below the hopper 11, and the bottom end of the feed chute plate 12 is located above the rear end of the sorting area, so that the fruits dropped from the feed chute plate 12 can be received by the rear end of the sorting area.

[0053] It also includes an elastically retractable buffer rod 3, two front rods 102 extending upward from the front end of the frame 1, the top of the front rod 102 is hinged to the front end of the swing seat 101, the rear end of the swing seat 101 is hinged to the top of the buffer rod 3, the bottom end of the buffer rod 3 is hinged to the frame 1, and the two sides of the reduction box 4 are provided with lower extension columns 41 extending outward;

[0054] The material chute plate 12 is rotatably mounted on the hopper 11, and upper extension columns 121 are extended outwardly on both sides of the front end of the material chute plate 12;

[0055] It also includes a steel wire rope 10. A connecting rod 103 is extended upward from the frame 1. The connecting rod 103 is rotatably connected to a pulley 2. The height of the pulley 2 is higher than the discharge end of the discharge chute plate 12 and is located between the lower extension column 41 and the discharge chute plate 12. The steel wire rope 10 passes over the pulley 2. One end of the steel wire rope 10 is fixedly connected to the lower extension column 41, and the other end is fixedly connected to the upper extension column 121.

[0056] When fruits of a certain weight are transmitted on the sorting unit 7, under the influence of gravity, the tail of the swing seat 101 will press the buffer rod 3 downward, thereby adjusting the inclination angle of the sorting unit 7, controlling the speed at which the fruits are transported downward in the sorting unit 7, driving the reduction box 4 to press downward, driving the wire rope 10 to press downward, and the other end of the wire rope 10 pulls the storage end of the discharging mechanism upward, reducing the inclination angle of the fruits when they are discharged, slowing down the speed at which the fruits fall, so as to avoid collisions on the sorting unit 7.

[0057] An output unit 8 and a baffle unit 9 are fixedly connected between the swing seats 101, a baffle unit 9 is arranged between two adjacent output units 8, and the output unit 8 is located directly below the sorting unit 7;

[0058] The output unit 8 includes a first material box 81, a second material box 82, a third material box 83 and a fourth material box 84 which are sequentially arranged on the swing seat 101 from top to bottom, and the baffle unit 9 includes a first baffle 91, a second baffle 92 and a third baffle 93 which are sequentially arranged on the swing seat 101 from top to bottom and have a triangular shape with a small top and a large bottom;

[0060] In one embodiment, the fruit stems can be prevented from getting stuck on the sorting unit 7 and affecting the transmission.

[0061] Specifically, the fruit 14 is put into the hopper 11, and the fruit 14 slides along the feeding chute plate 12 onto the sorting unit 7. Under the influence of gravity, the fruit 14 slides downward from the sorting unit 7, and after reaching a suitable gap, it falls into the output unit 8 below and is discharged from one side of the output unit 8. After the motor 5 is started, the power is transmitted to the output end of the reduction box 4, driving the first rotating shaft 71, the second rotating shaft 72, the third rotating shaft 73, the fourth rotating shaft 74 and the intermediate shaft 13 to rotate. The fruit on the sorting unit 7 will also rotate continuously, so that the fruit handle 141 is rolled by the rotating shaft and will not be stuck between the two rotating shafts. The fruit 14 falls down in order from small to large according to the fruit diameter for screening. When the fruit 14 contacts the smooth surface, it can accelerate downward movement. When it contacts the rough surface, it can increase the friction of the rotating shaft on the fruit, promoting the rolling of the fruit.

[0062] In another embodiment, the conveying speed of the fruit can be automatically adjusted to avoid collision.

[0063] Specifically, when fruits of a certain weight are transmitted on the sorting unit 7, when the fruits are too heavy, under the influence of gravity, the tail of the swing seat 101 will press the buffer rod 3 downward, thereby adjusting the inclination angle of the sorting unit 7, controlling the speed at which the fruits are transported downward in the sorting unit 7, driving the reduction box 4 to press down, driving the wire rope 10 to press down, and the other end of the wire rope 10 pulls the discharge chute plate 12 upward, reducing the inclination angle of the fruits 14 when they are discharged, slowing down the falling speed of the fruits 14, thereby avoiding collisions on the sorting unit 7.

[0064] The device is provided with a rotatable sorting unit so that the transported fruit can roll faster to prevent the fruit stem from getting stuck and misjudging the fruit diameter. At the same time, a pulley is provided to control the angle between the material discharge chute and the sorting unit, change the material discharge speed and reduce collisions. This solves the technical problem that in traditional fruit sorting, the sorting machine can only sort fruits with nearly spherical outer surfaces when screening fruit diameters. The fruit stems of fruits with fruit stems, such as cherries, oranges and mangosteens, are easily stuck on the sorting machine, causing the sorting machine to misjudge the fruit diameter of the fruit, causing certain losses to consumers and merchants.

For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
