Problems solved by technology

[0003] With the improvement of my country's per capita income and quality of life, people's demand for strawberries has risen sharply, and the requirements for strawberry quality have also increased year by year. However, strawberry grading technology in many areas is still relatively backward, resulting in different quality strawberries on the market. Restricts the development of my country's strawberry industry; currently, strawberry grading operations mainly use manual grading and some simple mechanical devices for grading operations; manual grading is labor-intensive and inefficient, and cannot meet the market's requirements for strawberry quality and freshness; simple machinery Strawberry grading by the device is mainly drum-type grading and V-shaped screening stick-type grading. The drum-type is to let the strawberries roll in the corresponding hole in the drum and fall off for grading. It is to let the strawberries slide down along the V-shaped screening sticks with gradually increasing spacing along with the gravity, and the strawberries fall and grade at the corresponding spacing, mainly based on the size of the strawberries, and the shape of the strawberries is changeable, and the size grading only for a single factor has certain advantages. limitations

Abstract

The invention discloses a strawberry external quality lossless grading device based on machine vision. The strawberry external quality lossless grading device comprises a lifting mechanism, a conveying mechanism, a visual discrimination mechanism, a screening mechanism and a control mechanism. The lifting mechanism is arranged at the leftmost end. The conveying mechanism is installed at the right end of the lifting mechanism. The visual discrimination mechanism and the screening mechanism are fixedly installed above the conveying mechanism left and right. The control mechanism is in electric signal connection with the lifting mechanism, the conveying mechanism, the visual discrimination mechanism and the screening mechanism. According to the strawberry external quality lossless grading device based on machine vision, on the premise that the requirement for convenient use is met, the effects of being simple in structure and convenient to operate are achieved, lossless grading can be conducted on the size, the shape, the appearance and other external qualities of strawberries, the safe using performance is good, and the practical using requirement is met.
