Automatic grading device for fruits and agricultural products

Abstract

The invention provides an automatic grading device for fruits and agricultural products, and relates to the agricultural field. The automatic grading device for the fruits and the agricultural products comprises a hopper, wherein the hopper is connected with one end of a grading mechanism; the grading mechanism comprises a V-shaped grading frame; a conveying belt is connected to the grading frame;the conveying belt is in transmission connection with a loading mechanism which is connected with the loading hopper through a transmission mechanism; and a speed reduction screen which is arranged in the length direction of the V-shaped grading frame is arranged below the V-shaped grading frame. According to the automatic grading device for the fruits and the agricultural products, the fruits with different size specifications are enabled to sequentially fall off, and the fruits can be graded according to the sizes in the most elaborate manner; a friction wheel which is connected with the conveying belt is connected with the loading mechanism through a transmission rod, the loading mechanism is enabled to synchronously rotate, and the fruits or the agricultural products can orderly enterinto the V-shaped grading frame, so that missing grading and wrong grading are avoided; and finally a shifting plate in the loading mechanism is designed to be arc-shaped, convex ribs are arranged onthe conveying belt, and the speed reduction screen is connected to the bottom end of the V-shaped grading frame, so that mechanical damage of the fruits in a grading process is avoided.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to an automatic grading device for fruits and agricultural products. Background technique [0002] Each country and region has its own grading standards. China divides fruit standards into four levels: national standards, industry standards, local standards and enterprise standards. A national standard is a standard that is approved and released by the national standardization authority and used uniformly throughout the country. Industry standards, professional standards, and ministry standards are standards that are approved and issued by competent authorities or professional standardization organizations in the absence of national standards, and are used uniformly within a certain industry. Local standards are standards that are formulated, approved and issued by local governments and used uniformly within the administrative region in the absence of national standards and industry sta...

Problems solved by technology

But generally speaking, the post-harvest commercialization of fruits in my country is far behind compared with developed countries. Only a few export commodity bases have fruit sorting equipment, and most of the areas use simple tools, according to size or weight. Manual grading, selection and packing one by one, low work efficiency

[0003] Due to different standards, the classification requirements of fruit
