Description

Automatic grading device for fruits and agricultural products

Technical Field

The invention relates to the field of agriculture, in particular to an automatic grading device for fruits and agricultural products.

Background

Each country and region has its own grading criteria. Chinese divides the fruit standard into 4 grades: national, industry, local, and enterprise standards. The national standard is a standard which is approved to be issued by a national standardization regulatory body and is uniformly used nationwide. The industry standard, professional standard and ministerial standard are approved and released by a director organization or a professional standardization organization under the condition of no national standard, and are uniformly used in a certain industry range. The local standard is a standard which is established, approved and issued by a local place without national standard and industry standard, and is uniformly used within the scope of the local administrative area. The enterprise standard is a standard which is formulated and issued by an enterprise and is uniformly used in the enterprise. International standards and national standards of each country are grading standards that are adopted by each country in the world. However, in general, the difference between the current postharvest commercialized treatment of fruits in China and developed countries is large, fruit selection equipment is only available in a few outsourced commodity bases, manual grading is carried out on the fruits according to sizes or weights in most areas by using simple tools, the fruits are selected and boxed one by one, and the working efficiency is low.

Due to different standards, the grading requirements of fruits and agricultural products are different, the existing grading of the fruits and the agricultural products is graded in stages according to the size or the weight of the fruits, but when the grading standard is higher, the existing grading equipment needs to be provided with a plurality of layers of grading mechanisms to refine the grading stages, the structure is complex, and the use is inconvenient.
