Description

The oblique funnel pipe type Kiwi berry quality selector of interval
Technical field
The present invention relates to Machinery Automation apparatus field, in particular it relates to the oblique funnel pipe type Kiwi berry quality of interval is chosen Select device.
Background technology
China is the maximum country of world's Kiwifruit Culture area, as the original producton location of main cultivation Kiwi berry, accounts for world's area More than half, particularly Qinling Mountains in Shaanxi northern foot area cultivated area accounts for 1/3rd of world's area up to 630,000 mu.But It is that no matter domestic Kiwi berry is all slightly poorer than New Zealand and other exported countrys in export price or in export volume, directly results in state Heavy economic losses of the family in agricultural product export trade, reason is exactly that China's Kiwi berry detection classification technique falls behind, and is mainly relied on The artificial graded operation for carrying out Kiwi berry, labour intensity is big, expends substantial amounts of labour, time, inefficiency.China's Hayward Kind kiwi fruit real mass, length and width, it is thick respectively 81.40~128.70g, 58.91~74.41mm, 45.85~ Between 57.13mm, 42.70~51.84mm, by statistical analysis, show that fruit quality exists with fruit geometric mean diameter aobvious The conclusion of the correlation of work, therefore we can be by detecting that Kiwi berry quality is classified.Therefore it is badly in need of interval tiltedly funnel pipe type Kiwi berry quality selector solves this technical barrier, but does not have such device in the market.
The content of the invention
This patent provides interval tiltedly funnel pipe type Kiwi berry quality selector, and mechanical structure of the present invention is simple, substantially reduces Labour intensity, time saving and energy saving, efficiency high solves the technical barrier that batch Kiwi berry quality grading is wasted time and energy.
