An adjustable precision fruit grading device

Abstract

The invention discloses an adjustable precision fruit grading device, which comprises a frame, a feeding conveying device, a grading device, a controller and a supporting device. The feeding and conveying device can evenly transport the fruit to the grading device for grading. The cam and connecting rod mechanism are used to allow the sieve plate to output movement and swing movement, and the movement range can be adjusted by the motor. The top fruit mechanism can avoid the phenomenon of fruit jamming and improve the efficiency of fruit grading. According to the principle of centrifugal force, the fruit can be graded, which can realize accurate and efficient fruit grading, and finally divide the fruit into different grades. Users can sieve according to their actual situation. The sieve plate can be replaced to adapt to different sieving materials, and the level can be adjusted by adjusting the support device to adapt to different grading environments. The invention has many advantages such as reliable operation, diversified functions, convenient maintenance, high classification efficiency, high classification precision and many classification types.

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...
