Abstract

The utility model relates to a simple identifier for early gathered cocoons and inside-stained cocoons. The utility model is a practical instrument for forsericulture (fresh cocoons purchase) in optoelectronic technology. The instrument can conduct the identifying and the discrimination without cutting open cocoons through the optimum photoelectric conversion and regulation, the gathering penetrating of the light and chromatographic analysis, and also according to each inherent characteristic diversity, such as the light penetration degree, morphology, colour and living body dynamic state, etc. of a health pupa, the early gathered cocoon (silkworm), a stiff silkworm, a dead silkworm and pollutant arranged in the cocoons. The utility model provides the simple and feasible testing instrument for the purchase of the fresh cocoons which are graded according to quality.

Description

Hair foot and the simple and easy identifier of internal contamination cocoon

The utility model is the Photoelectric Detection instrument, particularly a kind of simple detection instrument that is used for bright cocoon purchase to hair foot and internal contamination cocoon.

The hair callous skin on the feet be silkworm weave silk just intact or do not told as yet, the silk cocoon of larva before also not pupating.When bright cocoon was purchased, the hair callous skin on the feet caused very big loss to cocoon station, Silk Mill in mixing and being received in: 1, hair callous skin on the feet moisture content height, and silkworm is heavier than pupa, and hair callous skin on the feet ratio is big, dries by the fire corresponding the increasing of folding; 2, the hair callous skin on the feet mixes wherein, also is a reason of cocoon drying irregular (tender cocoon drying is mildewed easily in the storage); 3, in the bright cocoon purchase back pupa killing head baking, under high temperature stimulates, have sufficient silkworm to struggle, its foot is often grabbed random internal layer silk, and filament length shortens during filature, and the thread that falls increases, and increases the reel silk from cocoons folding; 4, because of preventing that maggot goes out moth, to receive cocoon and generally wanted the baking of pupa killing head the same day, hair callous skin on the feet (silkworm) is mixed in wherein, and the silkworm that is weaving silk is killed by high temperature, and the sericterium along the silk that do not spue in its body has just been lost.In recent years because raw silk sells well, there are not detection means or instrument that the hair callous skin on the feet is sold in practicable prevention again, so a large amount of hair callous skins on the feet are sold to the economic loss that country causes tens million of units.Conventional cutting cutd open the silk cocoon appreciation to differentiate way not only time-consuming, and main is the big content of starting materials cocoon of loss (cutting bad).When purchasing very big, the bright cocoon of filature influence, stiff egg, dead worm cocoon need buckle the level price reduction in its degree and ratio.

The problem that exists when purchasing in view of above-mentioned bright cocoon, task of the present utility model are to utilize a kind of simple and easy identifier of discerning mao foot and internal contamination cocoon of photoelectric technology design, to reduce the cocoon station greatly, the economic loss of Silk Mill.

The utility model provides a kind of simple and easy identifier that utilizes photoelectric technology to differentiate hair foot and internal contamination cocoon.This instrument has adopted opto-electronic conversion, the saturating of light to gather and chromatographic technique in design, need cut hurriedly and cut open bright cocoon, and directly the cocoon of having pupated, hair foot, stiff silkworm, dead worm cocoon are differentiated in appreciation.

This instrument is by the Lights section, level crossing, power control part branch, cocoon plate, watch window and light by-pass cock and light display lamp constitute, the Lights section is by light source, concave mirror and fly's-eye lens are formed, level crossing is inclined in differentiates the instrument middle part, and the light path face is concave mirror, light source, fly's-eye lens, cocoon plate loophole, level crossing in proper order.There is a watch window at middle part, instrument front, and the cocoon plate bottom has loophole, every hole to have inclined to one side number.

Below in conjunction with accompanying drawing the utility model is introduced in detail:

The simple and easy identifier stereogram of Fig. 1 hair foot and internal contamination cocoon

Fig. 2 power control circuit figure

Fig. 3 index path

Among the figure:

1, power line 2, light source 3, insert that cocoon mouth 4, reflective mirror 5, watch window 6, light by-pass cock 7, light display lamp 8, power control part divide 9,100W high-pressure halogen lamp 10, concave mirror 11, fly's-eye lens 12, cocoon dish 13, level crossing 14, watch window glass plate

Main light source 2 is contained in instrument top, and power control part divides 8 to be contained in the instrument bottom, and the bright silk cocoon container of purchase inserts by 3, and plane mirror 4 angle mounts are at the instrument middle part.There is a watch window 5 at middle part, instrument front.

The 220V electric main is delivered to 100W high-pressure halogen lamp 9 behind power control circuit, the high light that this lamp sends is radiated on the cocoon dish through concave mirror 10 optically focused and through the even directional light of fly's-eye lens 11 refraction back formation, loophole is arranged on the cocoon plate, there is numbering in each hole, and light can see through loophole and be radiated on the bright cocoon.Penetrate light and meet in the cocoon and absorbed to some extent, weaken behind different silkworm, pupa, the dirt, in imaging on the level crossing 13 and reflex on the watch window glass plate 14, the testing staff can observe resolution.Method of operating is: earlier this instrument power source plug is inserted 220V electric main socket, open light by-pass cock 6, to sample bright cocoon (being generally 25) pendulum on the cocoon plate eyelet by national regulation sampling 50 grams, the high light that inserts cocoon mouth, Halogen lamp LED is radiated on every sample cocoon through the hole on the cocoon plate, can be observed sample cocoon inner case by watch window.The cocoon of hair callous skin on the feet or internal contamination is write down the numbering of cocoon plate loophole, take out behind the cocoon plate and can reject bright cocoon, calculate the ratio of mao foot and internal contamination cocoon thus, the price of defining the level according to numbering corresponding to this hole.

The utility model is selected novel intense light source for use, both guaranteed economize on electricity safe in utilization by self-designed control circuit, reach best photoelectric conversion result, instrument has automatic in-position to put simultaneously, have only cocoon plate (when promptly detecting) time that puts in place to be derived from moving luminously, not only economized on electricity but also avoid the not in place and high light of cocoon dish by the stimulation of speculum to eye; Instrument also is provided with continuous adjustable device (among Fig. 1 6), can adjust according to different cocoons and tester's needs automatic demonstration is all arranged a little less than the break-make of light intensity and parallax, circuit and the light intensity (be arranged among Fig. 1 7), on the silk cocoon imaging correspondence position numbering is arranged on the watch window glass plate, it is number corresponding one by one with cocoon plate cocoon hole, be convenient to indicate which kind of type all kinds of cocoons belong to and check the number to cut when disputing and cut open, avoid cutting and cut open other silk cocoon.

Need not cut with this identifier and to cut open silk cocoon, appreciation quick and precisely, this instrument is badly in need of at the cocoon purchasing station.After using, each cocoon station only calculates that 50% silk cocoon is used this instrument appreciation instead and can be reduced and cut cocoon and lose up to ten million units by cuing open the cocoon appreciation, and prevents a large amount of hair callous skins on the feet to sell effectively, reduces the tens million of units of economic loss for Silk Mill and cocoon station with the province in Sichuan Province.
