Abstract
The utility model provides a measurer for pork fat and lean degree. The utility model utilizes a Y-shaped reflection type density modulation type fiber optic sensor to form a fiber optic probe. A slide potentiometer is used as a length sensor. A thickness measurement of hypodermal fat meat and hypodermal lean meat is realized for cattle butchered (in particular to a pork carcass) by a photoelectric conversion and an SCM process. The measurer for pork fat and lean degree is utilized in slaughtering industries and meat processing factories. The quality grade and the price grade of the meat can be regulated according to the measurer for pork fat and lean degree. The utility model simultaneously has the advantages of easy use, exact measurement, easy carry, good moisture resistivity, etc.
Description
The utility model relates to a kind of device that thickness is measured, and it is used for the livestock of butchering (especially pork trunk) is carried out the thickness measure of subcutaneous fat meat and lean meat.
At present, butchering in industry and the meat packing plant of China, the livestock of butchering is done the fat and lean degree judge just by visual inspection, judgement by rule of thumb, do not have accurate instrument to measure the thickness of its subcutaneous fat meat and lean meat, also just be difficult to the quality grade and the price grade of regulation meat in view of the above.
The purpose of this utility model is to provide a kind of device that can carry out the thickness measure of subcutaneous fat meat and lean meat to the livestock of butchering (especially pork trunk).
Solution of the present utility model is as follows:
It is to utilize the reflective intensity modulation optical fiber sensor of Y shape to constitute optical fiber probe, the head of optical fiber probe is elongated needle probe, sliding cylinder and compression spring that needle probe is pretended outward and answered length, spring is a hard point with probe joint and sliding cylinder end cap, brushgear housing is established in the rear end of sliding cylinder, dress brush on it, the rear end of probe joint connects the skeleton of a hollow, the hollow position of skeleton is the passage of optical fiber, skeleton is outer makes linear transducer around the potentiometer winding, sliding cylinder drives brush and endwisely slips in potentiometer winding upper edge, there is sleeve the outside of potentiometer, sleeve rear end connects cover plate and wiring board housing, light source is arranged in the housing, photodetector and amplification and rectification circuit, the coupled end of the input optical fibre bundle of optical fiber probe passes to the light source place, and the coupled end of the output fiber bundle of optical fiber probe passes to the photodetector place, and photodetector is again behind amplification and rectification circuit and light source, potentiometer links to each other with control and display by line together.
The structural representation of accompanying drawing 1. optical fiber probes.
Accompanying drawing 2. structural representations of the present utility model.
Be described further below in conjunction with drawings and Examples:
From figure, can be clear that, the shape of optical fiber probe similar " Y " shape, it is made up of two fibre bundles, one is the input optical fibre bundle 1 of incident intensity, one is the output fiber bundle 2 of reflective light intensity, two fibre bundles are merged into a branch of detection optical fiber bundle 3 equably in certain-length, support to form elongated needle probe 5 by the sleeve pipe 4 of rigidity; The sliding cylinder 6 of a respective length is adorned in the outside of needle probe, and it is to slide before and after axle is done with the needle probe, and needle probe is also just done corresponding flexible, and compression spring 7 is resetting-mechanisms of sliding cylinder; Probe joint 8 backs connect the skeleton 9 of a hollow, middle vacancy in the middle of the skeleton is the input of optical fiber probe and the passage of output fiber bundle, potentiometer winding 10 is twined as linear transducer in the outside of skeleton, be brush 12 on the sliding cylinder rear end brushgear housing 11 when sliding cylinder drives lower edge potentiometer winding and slides, can reflect that needle probe stretches out the outer length of sliding cylinder; The outer sleeve 13 of potentiometer is fixed on the probe joint and plays sealing process, simultaneously the handle of double as needle probe; Connect cover plate 14 and wiring board housing 15 behind the sleeve, carry out the photoelectricity coupling in the housing and amplify shaping, be that the coupled end of the input optical fibre bundle of optical fiber probe is led to light source 17 places and received the light that light source sends, and the coupled end of the output fiber bundle of optical fiber probe is led to photodetector 16 places the light intensity delivery that reflects is transferred to control and display again to photodetector behind amplification and rectification circuit 18.
The course of work of the present utility model is as follows:
The input optical fibre bundle of optical fiber probe arrives needle probe foremost with the light intensity delivery that light source sends, when needle probe pierces through the pork trunk from inside to outside, at air-lean meat, lean meat-fat meat, fat meat-air etc. are at the interface several, the reflective light intensity of returning from the intrafascicular transmission of the output optical fibre of optical fiber probe has significant change, utilize this jump signal, and be combined in the length signals value that the needle probe that obtained by linear transducer when the light intensity jump signal produces stretches out, can calculate and demonstrate the lean meat of pork trunk by control and display, fat meat thickness and gross thickness draw the ratio of lean meat and fat meat.
When calculating, a reference voltage U ' can be set, between the output voltage values of its value photodetector when light is in lean meat and fat meat, after shaping circuit is handled, can obtain:
When needle probe is in lean meat, output voltage U
r=" 0 ",
When needle probe is in fat meat, output voltage U
r=" 1 ",
When needle probe was in air, output voltage was again U
r=" 0 ";
If U
eBe the output voltage on the linear transducer, then:
When needle probe just with air-when the lean meat interface contacts, sliding cylinder non-displacement, output voltage U
E0=0,
Arriving on lean meat-fat meat interface after needle probe thrusts (is U
rBecome 1 from 0) time, output voltage U
E1=U
1,
Promptly to arrive on fat meat-air interface (be U when needle probe pierces through
rBecome 0 from 1) time, output voltage U
E2=U
2
If U
CcFor being added in the total voltage on the linear transducer, L is the total length of linear transducer, then by formula
L
i＝ (U
i)/(U
cc) L
Can obtain lean meat thickness (L
1), gross thickness (L
2) and fat meat thickness (L
2-L
1).
The utility model is in specific implementation process, rigid casing, the probe joint, sliding cylinder, sleeve, wiring board housings etc. are suitable to be made as with stainless steel material, the length of needle probe is greater than the typical position gross thickness of tested meat, the skeleton of hollow can be with making such as plastics, brushgear housing and brush are advisable with annular, preferably beat a little through holes on the wiring board housing, light source can be used the general visible source, photodetector adopts highly sensitive phototriode, amplification and rectification circuit adopts common operational amplifier and comparer to constitute, and adopts 8 one chip microcomputers to carry out data acquisition, handle and control, show.
As can be known, utilize the utility model can realize subcutaneous fat meat and the lean meat thickness of the livestock butchered are measured from top narration, can select typical position so that unify comparison when measuring, measuring display precision is ± 10%.It is applied to butcher in industry and the meat packing plant, can makes stipulations to the quality grade and the price grade of meat in view of the above.Advantages such as that the utility model also has simultaneously is easy to use, measure accurately, carry easily, moisture resistivity is good.
