Primary sorting and grading equipment for apples

Abstract

The invention relates to the field of agricultural equipment and particularly discloses primary sorting and grading equipment for apples. The equipment comprises a feeding device, a conveying device,an image acquisation device and a grading device, wherein the image acquisition device comprises a camera obscura which is fixed on a belt conveyer rack; through holes through which a conveyer belt ofa belt conveyer penetrates are respectively formed in side walls on both sides of the camera obscura; a plurality of halogen lamps in annular direction and a plurality of first CCD (Charge Coupled Device) cameras are arranged on the top wall inside a camera obscura cavity; a plurality of first CCD cameras in annular distribution and second CCD cameras in a middle position are positioned on the top wall inside the camera obscura cavity; the grading device comprises an image acquisition card, a computer and a plurality of hydraulic cylinders for executing grading instructions of the computer; telescopic ends of the hydraulic cylinders all face to the conveyer belt direction of the belt conveyer; push plates for pushing out apples on the belt conveyer are fixedly distributed at the telescopic ends. By adopting the equipment, harvested apples can be rapidly and accurately graded, then additional values of the apples can be increased, and furthermore the market competitiveness can be improved.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an apple primary selection and grading device. Background technique [0002] my country is the world's largest producer of fruits and vegetables, with an output of about 1 billion tons. Radiation has driven related industries to achieve an output value of more than 3 trillion yuan. However, there are many problems in the post-harvest treatment of fruits and vegetables. Take apples as an example: For a long time, In my country, there is a concept of pre-harvest production of heavy apples and post-harvest treatment of light apples. The post-harvest treatment rate is about 30%, which is far lower than the 70% level in developed countries, resulting in more than 30% of post-harvest rot losses in apple production areas. Direct economic losses exceeded 200 billion yuan. The main reasons for this situation are: lack of understanding of the intelligent quality grading of high-quality...
