Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of silkworm breeding, and in particular to a mechanism and method for preparing flat attached eggs from scattered eggs for detection. BACKGROUND

[0002] The number of good eggs, the good egg rate and the practical hatching rate of silkworm eggs are important indicators for the quality inspection of silkworm eggs in the standards “Silkworm First Generation Hybrid” (NY 326-1997) and “Silkworm First Generation Hybrid Inspection Procedures” (NY / T 327-1997) issued by the Ministry of Agriculture and Rural Affairs of China. At present, the detection of these three indicators in China is completed by visual identification and manual counting, and the detection effect generally has the disadvantages of low efficiency and large error.

[0003] Silkworm first generation hybrids are divided into scattered egg and flat attached egg according to the form of attachment. In recent years, the detection of the number of good eggs and the good egg rate of scattered eggs has been improved, and the number of eggs can be detected by digital image processing. Compared with the manual counting method, the efficiency is greatly improved. However, through investigation, the above method has the following three problems that are difficult to solve.

[0004] First, some silkworm eggs in the scattered eggs may be attached to each other, as shown in FIG. 1, when using digital image processing to investigate, the counting error will be caused by the attachment of the eggs. If the number of attached eggs in a certain sample is large, the error will be large. Moreover, since the eggs are only about 1 mm in size, it is difficult and time-consuming to separate them manually, and hard separation of the attached eggs may damage the eggs and affect the subsequent hatching rate investigation. Figure 7 Second, when counting the number of silkworm eggs, it is necessary to manually distinguish good eggs from bad eggs, then count them respectively using images, and then wrap the good eggs with paper to accelerate the green stage for hatching investigation. The bad eggs are identified by visual observation of the eggs by the naked eye. The bad eggs include yellow unfertilized eggs and dark brown dead eggs, and the egg surface has a triangular depression. However, during the investigation of good eggs in scattered eggs, some dark brown dead eggs have a deep color and the depression is not obvious, and the color difference with normal eggs is not large, which is difficult to distinguish accurately by the naked eye. However, as time goes by, the characteristics of the dead eggs will become more obvious, and more dead eggs may be found during the hatching investigation stage, and the number of good eggs and bad eggs counted before needs to be adjusted.

[0005] Third, the flat attached eggs are usually packaged in a paper bag, and the eggs are attached to each other in the bag. When using digital image processing to investigate, the counting error will be caused by the attachment of the eggs. If the number of attached eggs in a certain sample is large, the error will be large. Moreover, since the eggs are only about 1 mm in size, it is difficult and time-consuming to separate them manually, and hard separation of the attached eggs may damage the eggs and affect the subsequent hatching rate investigation.

[0006] Third, the number of good eggs, good egg rate, and practical hatchability are three important indicators for judging egg quality of silkworm eggs. The above method only improves the investigation of the number of good eggs and the good egg rate of loose egg seeds, but cannot replace the process of practical hatchability investigation. The investigation of practical hatchability requires daily statistics of un-hatched silkworm eggs starting from the next day of silkworm egg turning green, conversion of daily hatched silkworm eggs, and calculation of practical hatchability. Among them, daily statistics of un-hatched silkworm eggs need to select un-hatched silkworm eggs from silkworm eggs, white eggshells, and count them. The number of good eggs in a sample is about 1700, and the process of picking un-hatched silkworm eggs is time-consuming and laborious, and each sample needs to be repeated for three days. Therefore, the current investigation method of loose eggs cannot improve the efficiency of practical hatchability investigation. If the image recognition counting method is used for practical hatchability investigation of loose eggs, there is a big operation difficulty. There are short fluff on the silkworm, which is easy to entangle with white eggshells and un-hatched silkworm eggs. It is necessary to pick silkworm from a pile of white eggshells and un-hatched silkworm eggs, or pick white eggshells and un-hatched silkworm eggs from silkworm, and take pictures to identify and count silkworm. However, if the silkworm is not separated cleanly, it will cause large counting error of silkworm.

[0007] Currently, there are methods for detecting the number of good eggs, good egg rate, and practical hatchability of flat attached seeds. For example, the method for detecting the number of good eggs, good egg rate, and practical hatchability of flat attached seeds disclosed in the patent (publication number: CN115088683B). If loose egg seeds are prepared into flat attached seeds before detection, and then the above-mentioned patent (publication number: CN115088683B) is used for detection, the above-mentioned three problems can be effectively avoided.

[0008] In the prior art, in the process of making flat attached seeds from scattered eggs, an adhesive is usually applied on the cocoon paper, the scattered eggs are sown on the cocoon paper, and then the flat attached seeds are formed by sealing, indenting, punching, printing and shearing. The silkworm egg has an egg hole, and after the silkworm embryo is developed, the silkworm will bite the eggshell from the egg hole and crawl out. When the silkworm eggs are sown on the cocoon paper coated with adhesive, if the egg hole is just downward and contacts the adhesive, the egg hole will be blocked, the silkworm cannot come out, and the accuracy of the hatching rate investigation will be affected. Patent (publication number: CN102860290B) discloses a production method and equipment for silkworm egg flat attached seeds, which uniformly sows the scattered eggs on the cocoon paper, and then flattens the silkworm eggs by using a preset pressure to make the egg hole of the silkworm egg separate from the cocoon paper, so that the egg hole is separated from the paper surface, and the hatching rate of the detected silkworm eggs is affected. However, the method has the following problems: 1. When sowing the scattered eggs, if the egg hole is just downward and contacts the adhesive, although the silkworm egg is flattened by using a preset pressure to make the egg hole of the silkworm egg separate from the cocoon paper, so that the egg hole is separated from the paper surface, the adhesive may still remain in the egg hole, the egg hole is blocked, the hatched silkworm cannot come out smoothly, and the investigation result of the hatching rate is affected; 2. In the process of flattening the silkworm eggs by using a preset pressure, if there is a slight carelessness, the silkworm eggs may be damaged by the pressure and cannot hatch. If the production method of silkworm egg flat attached seeds disclosed in the patent (publication number: CN102860290B) is used to make flat attached seeds for detection, the scattered eggs may be damaged during the process of making flat attached seeds from scattered eggs, the silkworm eggs cannot hatch, or the egg hole of the silkworm egg is blocked, the hatched silkworm cannot come out smoothly, and the detection accuracy of the number of good eggs, the good egg rate and the practical hatching rate of the scattered eggs is affected.

[0009] Now the yield of scattered eggs accounts for about half of the national silkworm egg yield, so the quality inspection of silkworm eggs needs attention, and the task of silkworm egg quality inspection is heavy, and it is urgent to improve the inspection method of the number of good eggs, the good egg rate and the practical hatching rate of scattered eggs.

The top plate 3 can slide up and down inside the box 1 through the handle 31.

[0052] The adhesive silkworm egg paper 4 is detachably installed on the lower side of the top plate 3. The adhesive silkworm egg paper 4 can be made of kraft paper, and is a square with a side length of 5 cm. The lower side is coated with adhesive, and the upper side is attached to the lower side of the top plate 3 with double-sided adhesive.

[0053] The method of using this device is as follows:

[0054] The first box cover 2 is fixed to the lower end of the box body 1;

[0055] Weigh 1 gram of loose egg sample (fitted to the cross-sectional area of ​​25 square centimeters of the inner wall of the box 1, to detect as many loose eggs as possible at once, while avoiding excessive accumulation of loose eggs that may affect the detection) and scatter it into the box 1. Shake the box 1 to allow the loose eggs to be dispersed and spread evenly on the upper side of the first box lid 2.

[0065] The box body 1 is arranged in the same height, and when the first box cover 2 and the second box cover 5 are both installed on the box body 1, the first box cover 2 is parallel to the second box cover 5.

[0066] When used, the handle 31 penetrates through the slide 5 and is vertically and fixedly installed on the top plate 3, and then the top plate 3 is sleeved in the box body 1, and the second box cover 5 is fixed at the upper opening of the box body 1. The handle 31 can move the top plate 3 up and down parallel to the first box cover 2, and when the adhesive cocoon paper 4 adheres to the scattered eggs, the scattered eggs on the first box cover 2 can be adhered at the same time, so that the top plate 3 and the first box cover 2 are not parallel, and the local scattered eggs on the first box cover 2 are not damaged due to the large pressure. In order to facilitate the installation and disassembly between the second box cover 5 and the box body 1, the second box cover 5 and the box body 1 can be buckled.

[0067] In some technical solutions, further comprising:

[0068] A limiting plate 32 is arranged on the handle 31.

[0069] A resilient member 53 is arranged at the upper end of the slide 51 and surrounds the handle 31.

[0071] In actual use, the set height can be set to 0.5 to 1.5 cm above the first box cover 2, such as 1 cm, and when the top plate 3 is lowered to 1 cm above the first box cover 2 in the box body 1, the limiting plate 32 and the resilient member 53 are in contact, and when a downward force is applied to the handle 31, the resilient member 53 will give the handle 31 a rebounding force, so as to avoid the top plate 3 from being lowered too fast and causing damage to the scattered eggs.

[0072] Embodiment two

[0073] ​The application also provides a method for preparing flat-attached eggs for detection, comprising the following steps:

[0074] S1, fixing the first cover 2 at the lower end of the box body 1;

[0075] S2, scattering the weight of loose eggs matching the cross-sectional area of the inside of the box body 1 into the box body 1, shaking the box body 1, and making the loose eggs evenly spread on the upper side of the first cover 2;

[0076] S3, placing the glue mulberry seed paper 4 on the lower side of the top plate 3, exposing the glue, and moving the top plate 3 into the box body 1 and down, so that the loose eggs are adhered to the glue of the glue mulberry seed paper 4;

[0077] S4, moving the top plate 3 up, removing the first cover 2 from the box body 1, turning over the box body 1, and uniformly scattering the sterilized fine sand into the box body 1, so that the fine sand adheres to all the gaps between the loose eggs on the glue mulberry seed paper 4, and the fine sand that is not adhered is removed;

[0078] The fine sand adhered to the gaps between the loose eggs, on the one hand, avoids the inconvenience of removing the hatched ant larvae adhered to the glue mulberry seed paper 4 during the detection process, and on the other hand, the glue layer of the glue mulberry seed paper 4 has a reflective property. If the loose eggs are not completely covered on the glue mulberry seed paper 4, there are gaps between the loose eggs, and during the detection process, when the photo of the sample is taken, light spots are easily generated at the gaps between the loose eggs, affecting the recognition effect of subsequent detection, as shown in Figure 5 If the fine sand is adhered to the gaps between the loose eggs, a relatively rough surface will be formed between the loose eggs on the glue mulberry seed paper 4, thereby avoiding reflection when taking a photo, and facilitating subsequent image processing, as shown in Figure 6

[0079] In actual use, the smaller the particle size of the fine sand is, the better, such as fine sand with a particle size of 0.075-0.2 mm.

[0080] S5, removing the top plate 3 from the box body 1, and removing the glue mulberry seed paper 4 from the top plate 3.

[0081] The effect of the method can be seen in Example 1, which will not be repeated here.

[0082] When the sterilized fine sand is scattered into the box body 1 and the fine sand that is not adhered is removed, it may affect the adhesion of the loose eggs on the glue mulberry seed paper 4. Further, in the step S4, after removing the fine sand that is not adhered, a layer of elastic panel, such as a sponge, is laid on the fine sand and the loose eggs, the first cover 2 is fixed on the box body 1 again, the top plate 3 is moved up, and the first cover 2 is pressed to compress the elastic panel, so that the loose eggs and the fine sand are bounced by the elastic panel, and the loose eggs and the fine sand are firmly adhered to the glue mulberry seed paper 4.​

[0083] While the application has been described in detail with particular references to specific embodiments thereof, it will be apparent to those skilled in the art that various modifications or changes can be made in the application without departing from the spirit and scope thereof.
