Description
Technical Field
The invention relates to the technical field of materials, in particular to a reciprocating type ellipsoidal fruit and vegetable sorting and boxing system.
Background
With the development of agriculture in China, the sowing area of fruits and vegetables is increased from 333.09 ten thousand hectares in 1978 to 16665.0 ten thousand hectares in 2016. A large number of fruits and vegetables need to be classified and screened before distribution, and then sorted, boxed and distributed according to a customer order. The fruit and vegetable sorting and boxing is taken as one of the links of fruit and vegetable marketing, and is an important process for the added value of agricultural products. However, the traditional manual sorting has the defects of high labor intensity, easy error, low efficiency and the like, and is not suitable for the sorting and boxing treatment of the fruits and vegetables in large batches.
The development of fruit and vegetable agricultural products in developed countries is early, and the research on sorting systems is becoming perfect. A variety of fruit and vegetable sorting systems have been developed at this stage, and the products have evolved from traditional mechanical sorting to nondestructive testing sorting, with sorting categories including size, weight, appearance quality, internal quality, and the like. As represented by an electronic weighing type sorting machine manufactured by israel ESHET EILON company and us AUTOLINE company, the sorting detection technology is mature, the working efficiency is high, and the sorting precision is high.
The fruit and vegetable sorting and boxing system in China is late to start, scientific research investment is insufficient, and the like, so that the field of fruit and vegetable sorting and boxing in China is far behind the developed western countries, and a great gap exists. In recent years, along with the increasing emphasis of competition in fruit and vegetable markets and sorting and boxing of fruits and vegetables in China, more and more students begin to study the fruits and vegetables. If surname is reserved, a long roll shaft which can be lifted by a slide block on a chain plate is arranged between the two short roll shafts to realize the sorting of the size of the potatoes; wei Xinhua designs a conveying and unloading structure combining the double-cone roller and the lever and optimizes a bus of the double-cone roller, thereby realizing stable conveying and unloading of fruits; ge Jishuai adopts the structure of fruit tray and realizes that fruit is classified according to weight size through the design to weighing module.
However, the existing fruit and vegetable sorting can only effectively solve the problem of the quality requirement of the national on the fruits and vegetables. After classified screening, fruits and vegetables are sorted, boxed and distributed according to the customer orders. Fruit and vegetable sorting and boxing are one of important links of fruit and vegetable marketing, and currently, boxing is mainly carried out manually. The operator needs to manually put fruits and vegetables into the box according to the weight required by the customer order, the labor intensity is high, the time is long, the error rate is high, and the efficiency is low. Meanwhile, the quality guarantee period of the fruits and vegetables is short, and the freshness of the fruits and vegetables directly influences the price and sales of the fruits and vegetables. Therefore, the fruit and vegetable sorting and boxing equipment capable of replacing manual automatic sorting is designed, the fruit and vegetable sorting efficiency can be greatly improved, the circulation link from field picking to distribution of fruits and vegetables is shortened, and informatization and automatic development of agricultural products are promoted.
