A rotary lever type fruit unloading mechanism, fruit sorting device and control method

Abstract

The invention provides a rotary deflector rod type fruit unloading mechanism, a fruit sorting device and a control method. The rotary deflector rod type fruit unloading mechanism comprises a steppingmotor, a deflector rod and spring pieces. The deflector rod comprises three branch rods with the mutually-connected top ends. The included angle between every two branch rods is 120 degrees, the two spring pieces with the include angle of 120 degrees are mounted at the tail end of each branch rod, the plane where each spring piece is located is perpendicular to the plane where the deflector rod islocated, the adjacent spring pieces on every two branch rods are mutually parallel, the deflector rod is fixedly mounted on a motor shaft of the stepping motor, and the stepping motor can rotate forwards and reversely. The rotary deflector rod type fruit unloading mechanism is simple in structure, convenient to manufacture, small, convenient to demount and easy to maintain. The fruit sorting device uses the fruit unloading mechanism, multi-grade sorting of fruits can be achieved according to the demands, and grading is accurate.

Description

technical field [0001] The invention relates to the field of agricultural products, in particular to a rotary lever type fruit unloading mechanism, a fruit sorting device and a control method. Background technique [0002] Fruit grading is a process to improve the commercial value of fruit and a necessary step before fruit packaging. Production bases with large fruit output have gradually adopted fruit automatic grading machines instead of manual fruit grading. The disclosed fruit unloading device comprises a mechanical unloading device and a pneumatic unloading device. The mechanical unloading device drives mechanical devices such as cams, connecting rods, and levers to move through electromagnetic drives such as electromagnets to separate the fruit from the conveyor line. The conveyor line needs a long stroke to complete the grading unloading operation, and the manufacturing process of the device is complicated. , the manufacturing cost is high, and the volume is huge af...

AI Technical Summary

Problems solved by technology

The mechanical unloading device drives mechanical devices such as cams, connecting rods, and levers to move through electromagnets and other electromagnetic drives to separate the fruit from the conveyor line. The conveyor line needs a long stroke to complete the grading unloading operation, and the manufacturing process of the device is complicated. , the manufacturing cost is high, and the volume is huge after being combined with the conveyor line

The pneumatic unloading device ejects the high-pressure gas generated by the cylinder from the nozzle, thereby blowing the fruit away from the conveying line. The pneumatic device requires a high-pressure air source, which is large in size and loud in noise. After the fruit is blown by the air, it is easy to cause inaccurate grading movement direction.
