An intelligent sorting machine for carrots with a rotating fruit holder

Abstract

The invention discloses an intelligent carrot sorting machine with a rotary fruit support. A mechanical device and a computer vision technology are combined to automatically grade long-rod-shaped vegetables and fruits including carrots and the like. The intelligent carrot sorting machine is mainly composed of a biased movable fruit support conveying grading device, a movable pin type locking device and a data analysis and acquisition device, wherein a fixed part of a biased movable fruit support is mounted on a conveying chain; and a rotary roller shaft of a movable part of the biased movable fruit support is used for enabling carrots to rotate and enter a CCD (Charge Coupled Device) camera field of a machine vision system, and an obtained image is analyzed and processed by an image processing manner to obtain information including shapes, sizes, green heads, cracks and the like of the carrots. In a grading process, the intelligent carrot sorting machine is controlled by a pneumatic element to fix the movement of a movable pin lock of the movable fruit support so that the machine is overturned to download materials under the action of the gravity. When the fruit support is reset, the movable pin type locking device is fixed on the conveying chain again by the matching of an inclined slope and a spring. The sorting machine can be used for efficiently grading and sorting the carrots so that the great labor force is released; and the structure is simple, the operation is convenient, and the blank of national long-rod-shaped vegetable and fruit grading machines is filled.

Description

technical field [0001] The technical solution of the invention belongs to the technical field of food processing, and in particular relates to a device for fully automatic grading by using machine vision technology to detect the appearance quality of carrots. Background technique [0002] Fruit and vegetable sorting is an important link for fruits and vegetables to enter the circulation field. Fruit and vegetable grading and sorting is conducive to improving the market competitiveness of fruits and vegetables and accelerating the commercialization process. In our country, there are few enterprises researching mechanized fruit and vegetable grading, and the equipment is also lagging behind developed countries. The grading work basically relies on the cooperation of machinery and labor. [0003] The commonly used fruit and vegetable sorting devices include screening type, drum type, rotary belt type, and roller type. However, these sorting devices are mainly for spherical and ...

AI Technical Summary

Problems solved by technology

The chain-roller grading conveying device needs to cooperate with a separate grading and unloading mechanism, and uses the principles of pushing, hitting, and turning to send fruits and vegetables from the two rollers. However, the axial dimension of the long rod-shaped fruits and vegetables is too long, which leads to The execution stroke of the device is too long, and the efficiency of the whole machine decreases

[0005] The movable fruit tray type conveying and sorting device adopts the fruit tray with rollers to support the fruits and vegetables, and controls the magnetic fruit beating device fixed on the frame to overturn the fruit tray, so that the fruit tray is turned over and the fruits and vegetables roll down from above. The fruit holders above are suitable for spherical fruits and vegetables such as apples, but not for long stick fruits and vegetables
