An apple primary selection grading device

Abstract

The invention relates to the field of agricultural machinery and equipment, in particular to an apple primary selection and grading equipment. It includes feeding device, conveying device, image acquisition device and grading device; the image acquisition device includes a dark box fixed on the belt conveyor frame, and the side walls on both sides of the dark box are respectively provided with conveyor belts for the belt conveyor to pass through. perforation, on the top wall in the dark box cavity, a plurality of halogen lamps and a plurality of first CCD cameras distributed in a ring are arranged, on the top wall in the dark box cavity and located at the top of a plurality of first CCD cameras distributed in a ring There is a second CCD camera in the middle position; the grading device includes an image acquisition card, a computer, and multiple hydraulic cylinders that execute computer grading instructions. Apples on the conveyor are pushed out by push plates. The invention can improve the added value of the apples by quickly and accurately grading the harvested apples, thereby improving market competitiveness.

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...

[0002] my country is the world's largest producer of fruits and vegetables, with an output of about 1 billion tons.

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. The direct economic loss exceeds 200 billion yuan

The main reasons for this situation are: lack of understanding of the intelligent quality grading of high-quality apples, the serious lag in the development of related domestic equipment, resulting in low added value of apple products, poor market competitiveness, post-harvest production technology index system, and standardized standards lack
