Description
Technical field
The present invention relates to a kind of detection device more particularly to a kind of multi-purpose fruits and vegetables inside quality detection devices.
Background technology
Fruit, is essential thing in mankind's daily life, and fruit can not only largely supplement the dimension of needed by human body
The needed by human body nutritional ingredients such as raw element, minerals, inorganic salts, and can also balanced human dietary fiber.In order to ensure body
The nutriments such as a large amount of vitamin can be taken in daily, and people are often in buying a large amount of fruit and placing refrigerator.And fruit kind
Class is various, taste is different, of all kinds, has different types of fruit listing each season (such as：The pineapple in spring, summer
Watermelon, grape, the shaddock in autumn, apple, the navel orange in winter etc.)；Therefore, there is diversified selection for fruit people.
And when certain fruit of this season lists, various this season fruit normally can easily be bought by people for convenience, fruit warp
It sells the chamber of commerce and the fruit of this season is carried out largely wholesale into purchasing, meet the needs of people are to this season fruit with this.
In daily life, people often rely on quality of the experience of itself to fruit internal quality when selecting fruit
It being weighed, people generally carry out the judgement of quality by the shape feature of color and luster and surface to fruit surface,
Have by patting fruit, listens the acoustic situations that fruit internal is sent out to judge the method for fruit quality quality (such as：Select watermelon,
"Hami" melon etc.).These artificially judge the mode of fruit quality, it is desirable that judgement person possesses abundant experience, but still passes through after all
The subjective sensation of people judges, to a certain extent for inadequate scientific and precise, the case where inevitably will produce erroneous judgement.
Fruit quality in order to ensure customer's purchase is qualified, fruit from picking process to packaging process in will pass through multiple tracks
Process detection, avoid the problematic fruit of inside quality from being sold in customer's hand.After fruit is complete from orchard picking, people is detected
Member can carry out corresponding quality testing (such as to the fruit for putting fruit basket into：Sour-sweet degree etc.), and quality be detected it is problematic
Fruit then can be selected out.Existing detection mode is to measure fruit sugariness and internal soundness using hand-held saccharous detector,
Or it carries out carrying out internal soundness detection by way of experiment measures related fruit data cutting fruit.However, cutting fruit
Although the mode measurement data for detecting internal soundness is accurate, to damage experiment, tested fruit can not carry out after experiment for experiment
Sale, and experimental period length is unfavorable for the quick detection of fruit internal quality；Fruit quality is detected using hand-held saccharous detector, then is
Fruit is irradiated by detecting light source in the course of work, receiving detection part using the light source in device receives light source irradiation
Spot signal on fruit surface, this working method are the general technological means of existing detection device, such detection side
Although formula will not damaged fruit, to need man-hour manually hand-held device to measure time-consuming and laborious when measuring, and detection efficiency is low, and unfavorable
In the automatic detection of fruit internal quality.How efficiently, nondestructively solve the problems, such as that fruit internal quality detects, then becomes
The problem that the technical staff in fruit packaging field is faced.

Service life is also high.When detecting that some fruit internal quality is not up to standard, controller will send corresponding electric signal to follow-up
Screening plant, the problematic fruit of internal soundness is screened.When sorted fruits device is transported to the fruit on conveyer belt
When fruit with the detection of detection device before is not similar fruit；The device that first stops then is needed, is first stretched according to the adjustment of the diameter of fruit
The collapsing length of contracting bar so that controller controls the detection time of detection light source and light source reception detection part, then controls motor
Lead screw is driven, the center that detection light source receives detection part and tested fruit with light source is enable to be located substantially at same level
On.After waiting for that device has adjusted, the present apparatus can be made to carry out inside quality detection to new fruit to be measured, completed to different fruits and vegetables
Inside quality detection.
It is not only time saving and energy saving to be detected to fruit internal quality using the present apparatus, but also greatly improves detection fruit
The working efficiency of inside quality, while allowing the device to carry out inside quality detection to different types of fruits and vegetables, and should
Device can be suitable for large batch of fruit internal quality and detect, and avoid shakiness when manual operation instrument detection fruit quality
It is qualitative；Which solves existing detection devices to ask what the inside quality of variety classes fruits and vegetables was detected automatically simultaneously
Topic, also achievees the purpose that use manpower and material resources sparingly.
The signal control that signal control, detection light source and the light source of inductor receive detection part in the present apparatus is all by total
Controller is controlled to adjust, which is microcontroller or PLC, can be by the PC control controller come to device
In controlled element carry out real-time control, realize assembly line each section operational coordination.
Motor, elevating screw, feed screw nut, detection light source, light source receive detection part, telescopic rod, inductor, monolithic
Machine, the universal component that PLC is the fields prior art, connection structure and operation principle are the existing ripe skill in this field
Art, details are not described herein again.
The foregoing describe the technical characteristics of the present invention and basic principle and associated advantages, for those skilled in the art
For, it is clear that the present invention is not limited to the details of above-mentioned exemplary embodiment, and without departing substantially from the present invention design or
In the case of essential characteristic, the present invention can be realized in other specific forms.Therefore, in all respects, should all incite somebody to action
Above-mentioned specific implementation mode regards exemplary as, and is non-limiting, the scope of the present invention by appended claims and
It is not that above description limits, it is intended that all changes that come within the meaning and range of equivalency of the claims are included
Within the present invention.
In addition, it should be understood that although this specification is described according to each embodiment, not each embodiment is only
It contains an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art answer
When considering the specification as a whole, the technical solution in each embodiment may also be suitably combined to form art technology
The other embodiment that personnel are appreciated that.
