Adjustable precise fruit-grading device

Abstract

The invention discloses an adjustable precise fruit-grading device. The adjustable precise fruit-grading device comprises a machine frame, a feeding and conveying device, a grading device, a controller and a supporting device. The feeding and conveying device can convey fruits evenly to the grading device for grading, a cam and a connecting rod mechanism are used for enabling a sieve plate to carry out output moving and swinging movement, and the size of moving range can be adjusted by a motor. A movable fruit push-out mechanism is installed on the adjustable precise fruit-grading device, so that the fruits are avoided from seizing, and the efficiency of fruit-grading is improved; the fruits are graded according to a principle of centrifugal force, so that the fruits can be graded accurately and efficiently, and finally the fruits are divided into different grades; users can sieve objects according to actual needs, and the sieve plate is placed to adapt to various sieving objects; andlevelness is adjusted by adjusting of the supporting device to adapt to various grading environments. The adjustable precise fruit-grading device has the advantages of reliable operation, diversifiedfunctions, convenient maintenance, high grading efficiency, high grading accuracy, a plurality of grading types and the like.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to an adjustable precision fruit grading device. Background technique [0002] At present, the fruit needs to be graded during the actual picking and packaging process, and most of the sieved fruits are manually graded. The manual grading method leads to low work efficiency, high cost, and poor actual grading effect. The use of vibration classification has certain applications in fruit classification, but most of the classification devices on the market only use one classification method, that is, to carry out vibration classification according to the shape of the fruit. The device uses one degree of freedom movement and the amplitude is small. Insufficient tumbling during the process leads to the fact that the round holes on the grading sieve plate are easily stuck by "fruits", resulting in low grading efficiency, long grading time and a lot of energy con...
