Abstract
A kind of device for the quality information that collects fruit the utility model discloses quick nondestructive.Described device includes two pieces of support plates and inclined impact plate, fixed mesa and sensor with difference in height；Two pieces of support plates are vertically fixed on using stud on horizontal fixed mesa, screw is respectively adopted in inclined impact plate both ends and the top of two pieces of support plates is fixed, the height difference of two pieces of support plates makes inclined arrangement between inclined impact plate and horizontal plane, sensor be fixedly mounted on inclined impact back.The mode that the utility model hits inclined impact plate by using fruit free-electron model obtains the vibration information of fruit to the quality information that collects fruit, and does not destroy tested sample, detection efficiency is high, significantly reduces detection device cost.
Description
Technical field
The utility model is related to fruit quality detection method, more particularly to a kind of quick nondestructive collects fruit quality information
Device.
Background technology
China is known as the laudatory title of " fruit kingdom of the world ", and the fruit of almost all kinds has production and yield is high, but by
Fall behind in detection classifying equipoment, fruit is still inadequate in competitiveness in the international market, and outlet rate is relatively low, and fruit is in post harvest transport process
It is middle to there is a problem of Ripening and Softening and rotten.Accurately detect fruit quality, for determination suitable harvest time, adopt after protect
It deposits, assess the best edible period and grading etc. and be all of great significance.
Traditional fruit hardness detection method is mainly sampled, and several test points is chosen usually at the equator of sample, so
It removes the peel, is measured with certain distance inside Texture instrument or hardometer indentation fruit, this is a kind of destructive detection, inspection in test point afterwards
It is low to test rate, it is time-consuming and laborious and cause largely to waste.Therefore, it is necessary to find a kind of lossless detection method of fruit quality, realize
The Fast nondestructive evaluation of fruit quality.
Acoustic vibration detection technique is a kind of skill of the acoustic vibration characteristic progress fruit quality non-destructive testing using fruit
Art.Reflection characteristic that the acoustic vibration characteristic of fruit refers to fruit under sound wave or vibration wave effect, scattering properties, transmission are special
Property, absorption characteristic, attenuation coefficient, spread speed and the acoustic impedance of itself and intrinsic frequency etc., they reflect sound wave and shake
The basic law of dynamic wave and fruit interaction.Changes in microstructure occurs from inside in fruit maturation, to change
Its acoustic vibration characteristic.Therefore, acoustic vibration detection technique is feasible in theory for the detection of fruit quality.
Utility model content
In order to solve the problems, such as that fruit quality conventional test methodologies exist, the utility model aim is the provision of a kind of fast
The device of the lossless quality information that collects fruit of speed.
The technical solution adopted in the utility model is：
Described device includes two pieces of support plates and inclined impact plate, fixed mesa and sensor with difference in height；Two pieces
Support plate is vertically fixed on using stud on horizontal fixed mesa, and screw and two pieces of branch is respectively adopted in inclined impact plate both ends
The top of fagging is fixed, and the height difference of two pieces of support plates makes inclined arrangement between inclined impact plate and horizontal plane, sensing
Device is fixedly mounted on inclined impact back.
The inclined impact plate is one flat plate.
The angle of the inclined impact plate and horizontal plane is more than 45 degree, is produced with inclined impact plate after falling to avoid fruit
Raw secondary impact.
The sensor is the sensor for measuring impact force.
Compared with the background art, the utility model has an advantageous effect in that：
Utility model device does not destroy tested sample, and detection collecting efficiency is high；Meanwhile compared to existing most of water
The lossless acquisition modes of fruit quality, significantly reduce detection device cost.
Description of the drawings
Fig. 1 is the apparatus structure schematic diagram of the utility model.
In figure：1, the first support plate；2, inclined impact plate；3, fruit；4, data collecting card；5, computer；6, second
Fagging；7, fixed mesa；8, sensor.
Specific implementation mode
The utility model is described in further detail with implementation below in conjunction with the accompanying drawings.
As shown in Figure 1, device includes two pieces of support plates 1 and 6, inclined impact plate 2,7 and of fixed mesa with difference in height
Sensor 8；First, second support plate 1,6 is vertically fixed on using stud on horizontal fixed mesa 7,2 liang of inclined impact plate
Screw is respectively adopted for end and the top of the first, second support plate 1,6 is fixed, and the height difference of two pieces of support plates 1,6 to tilt
Inclined arrangement between impingement plate 2 and horizontal plane, sensor 8 are fixedly mounted on inclined impact plate 2 using mounting screw or glue
The back side.
Inclined impact plate 2 is one flat plate, and material includes but not limited to aluminium alloy, plastics, rubber etc..Inclined impact plate 2
It is more than 45 degree with the angle of horizontal plane, after falling to avoid fruit 3 and inclined impact plate 2 generates secondary impact.
Sensor 8 is the sensor for measuring impact force, including but not limited to piezoelectric transducer, acceleration transducer etc..
Specific implementation further includes computer, and sensor 8 is connect through data collecting card 4 with computer 5.
The course of work of the utility model is：
Fruit is fallen to from eminence freely falling body on inclined impact plate 2 so that and inclined impact plate 2 generates vibration by impact,
Sensor 8 detects the vibration of inclined impact plate 2, and acquisition obtains vibration signal and is transferred in computer 5, to realize use
The mode of fruit free-electron model shock generation impact vibration obtains the vibration information of fruit.Subsequently combine corresponding signal processing side
Method and chemometrics method establish the quality prediction model of fruit, carry out the Fast nondestructive evaluation of fruit quality.
