Description
Technical field
The invention belongs to the fruit quality checkout equipment, relate in particular to a kind of fruit grading device.
Background technology
Fruit pluck or transportation in, be subjected to the not breakage but injured surface has the deepening slightly of slight depression, color and luster of mechanical damage or injury region epidermis because the effect of external force makes its epidermis, naked eyes are difficult to perceive.Damaging, abrading is one of leading indicator of fruit grading, and along with the prolongation of time, the brown stain gradually of pars affecta branch finally causes whole fruit rot and influences other good fruits, has a strong impact on economic benefit.In the fruit grading standard, the tolerance of indexs such as fruit shape, defected surface, color, maturity, only the vision with the people is difficult to accurate differentiation, and the people uses eye for a long time, can cause the instability of visual fatigue and mood, cause the classification error big, reliability is low, and therefore traditional artificial classification has been subjected to great limitation; Secondly, it all is to diminish detection that traditional fruit internal quality detects, thereby can not test to whole fruit, can only adopt the method for sampling.Along with the development of agricultural automation degree and warmhouse booth technology, the output of China's fruit has significant raising, and not only the amount of labour is big for traditional artificial counting, productivity ratio is low, has been difficult to meet the demands.
Summary of the invention
Big for the complicate statistics, the amount of labour that overcome existing fruit grading technology, production efficiency is low, the deficiency of poor reliability, the invention provides a kind of automatic grading of fruits device that reduces the amount of labour, enhances productivity, improves reliability.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of automatic grading of fruits device, described grading plant comprises casing, install in order to carry the entrance conveyor of fruit to be fractionated on described casing top, the outlet of described entrance conveyor is positioned at the top in order to the transparent caching hoop that cushions fruit, big up and small down horn-like of described transparent caching basketry, the bottom of described transparent caching basketry is provided with the elasticity outlet, and the internal diameter of described elasticity outlet is littler than described fruit external diameter to be fractionated; The below of described transparent caching hoop arranges the triangle steering gear, the limit, left side of described triangle steering gear is positioned on first exit conveyor, the right edge of described triangle steering gear is positioned on second exit conveyor, the bottom of described triangle steering gear has tooth bar, described tooth bar and power gear engagement, the rotating shaft of described power gear is installed in rotation on the casing; The side of described transparent caching hoop is installed the spectrum video camera, described spectrum video camera be connected for the intelligent classification discrimination module of certified products in order to judging whether according to spectrum picture, but described intelligent classification discrimination module is connected with the control motor of rotating, described control motor is installed on the casing, and the output shaft of described control motor is connected with the rotating shaft of described power gear.
Further, described casing is provided with in order to the upper hopper chute of placing entrance conveyor, in order to first gliding groove of placing first exit conveyor with in order to place second gliding groove of second exit conveyor.
Further again, on the described casing display is installed, described intelligent classification discrimination module be connected in order to the statistical module of adding up qualified fruit quantity and defective fruit quantity, described statistical module is connected with described display.
Technical conceive of the present invention is: high spectrum video camera assembly comprises imaging spectrometer, camera lens and image pick-up card, can record pictorial information and the spectral information of fruit simultaneously, wherein pictorial information can reflect the external sort feature of fruit, and spectral information can reflect the inside quality feature of fruit, and converts the analog signal that collects to data signal by image pick-up card.
By the spectral information threshold range of qualified fruit is set, belong in this threshold range when collecting current fruit to be fractionated, then judge to belong to qualified fruit; Do not belong in this threshold range when collecting current fruit to be fractionated, then judge to belong to defective fruit; And by control executing agency's (steering gear), make fruit transfer out by different output channels, realize classification.
Beneficial effect of the present invention mainly shows: reduce the amount of labour, enhance productivity, improve reliability.
