Multi-stage fruit and vegetable grading machine

Abstract

The invention discloses a multi-stage fruit and vegetable grading machine. The multi-stage fruit and vegetable grading machine comprises a rack, a power device, a transmission device, a grading connecting rod rotary group and a connecting rod spacing regulating device, wherein the power device drives the grading connecting rod rotary group to rotate through the transmission device; the connectingrod spacing regulating device regulates spacing between every two adjacent connecting rods in the grading connecting rod rotary group; the connecting rod spacing regulating device comprises a regulating guide rail, a height regulating mechanism and a lengthened chain plate; hinged ends of telescopic chain plates are connected with the connecting rods and main bearings, and the other ends of the telescopic chain plates are connected with the lengthened chain plate; and the two telescopic chain plates between the two connecting rods and the lengthened chain plate define a Y-shaped structure. Themulti-stage fruit and vegetable grading machine solves the problems of great working strength, long time and high randomness of manual fruit and vegetable grading work, overcomes the defect that spacing in work of conventional automatic fruit and vegetable grading machinery is un-adjustable, and can set and regulate needed different grading spacing in once grading work.

Description

technical field [0001] The invention belongs to the technical field of fruit and vegetable grading, and in particular relates to a multi-stage fruit and vegetable grading machine. Background technique [0002] Fruits such as cherry tomatoes and red dates, as well as vegetables such as potatoes and garlic, are easy to store, have good nutrition and are cheap. With the improvement of people's living standards, the market demand is increasing year by year. [0003] The size of fruits and vegetables is the key to determining the purchase price, and it is also the basis for product classification of wholesale and retail enterprises. At present, fruit and vegetable wholesale and retail enterprises generally sort vegetables manually when purchasing and selling vegetables. Not only is the work intensity of the workers high, the efficiency is low, but also the randomness is large, and the classification is not standardized. At the same time, due to the long sorting time, it will al...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to invent a fruit and vegetable grading machine to solve the problems of high manual grading intensity, low efficiency, irregularity, etc., and at the same time make up for the inability of traditional fruit and vegetable sorting machinery to satisfy one working cycle to realize multi-level sorting and working process. The defect that the grading specifications cannot be adjusted arbitrarily. In addition, it provides higher grading accuracy for smaller fruits and vegetables such as jujubes.
