Description

Technical Field

[0001] This invention belongs to the field of silverfish processing technology, specifically an automatic sorting machine for silverfish processing. Background Technology

[0002] China is the origin and main distribution area of ​​the world's whitebait (Salangidae family). Fifteen of the world's seventeen whitebait species are found in the coastal waters of eastern China (including the Yangtze River basin) and estuaries of major river systems, including six endemic species. For example, the Zhuhu small whitebait from the Zhuhu section of Poyang County in Poyang Lake is the smallest known whitebait species, but its nutrient content is much higher than that of larger whitebait. Whitebait has high nutritional and economic value and is an important economic fish species. Whitebait has a short life cycle, dispersed generations, and strong reproductive and sedentary abilities. As typical r-strategists, whitebait is sensitive to environmental changes and responds quickly, resulting in rapid population fluctuations. Over a long evolutionary process, it has developed rich diversity in its interspecific feeding habits, growth, and reproduction, among other biological and ecological characteristics.

[0003] In existing technology, silverfish of different sizes are sorted by sieve plates, which makes it easier to classify them. However, silverfish have a low oxygen content and small gills. They may not be able to survive because of the low amount of oxygen exchanged by their gills, or because their gills are easily dried out and die. Therefore, dead and stale silverfish need to be removed during processing to ensure their freshness. Summary of the Invention

[0004] To address the aforementioned problems, the present invention aims to provide an automatic sorting machine for processing silverfish, capable of sorting the freshness of silverfish based on the proportion of the white area.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: an automatic screening machine for processing silverfish, comprising a feeding barrel, an opening at the top of the feeding barrel, a first water pipe connected to the top of the feeding barrel, and a screening device connected to the feeding barrel;

[0006] The screener includes a first transport pipe connected to a feed hopper, a freshness detector connected to the end of the first transport pipe away from the feed hopper, and a second transport pipe connected to the end of the freshness detector away from the first transport pipe.

[0007] The freshness detector includes a housing, inside which are a controller, a camera, a light source, and a power supply. The camera is located on the side of the housing near the top of the first transport tube, and the light source is located on the side of the housing near the bottom of the first transport tube. Both the camera and the light source are equipped with waterproof transparent plates. The light source is a colored light source. A first valve is installed inside the first transport tube, and a second valve is installed at the connection between the second transport tube and the freshness detector. A discharge port is provided on one side of the housing, and a third valve is installed inside the discharge port.

[0008] The controller is used to acquire images captured by the camera, determine the proportion of the white area in the image, and when the proportion of the white area is greater than a preset range, open the third valve and close the second valve. When the proportion of the white area is less than the preset range, open the second valve and close the third valve.

[0009] The above solution achieves the following beneficial effects: users can add silverfish through the feeding bucket, and the first water pipe will continuously inject water into the feeding bucket to maintain the water level in the feeding bucket.

[0010] Initially, the first valve is closed. When the first valve opens, the feed bucket will flow into the first transport pipe, carrying silverfish. Once the silverfish enter, the first valve will close to prevent other silverfish from entering. Then, a light source will shine on the bottom of the silverfish. Because silverfish are translucent when alive, but within one hour of death, their proteins denature due to disrupted internal regulatory mechanisms, gradually changing from translucent to snow-white. Therefore, the color under a colored light source can reflect the freshness of the silverfish.

[0011] When the proportion of the white area detected is greater than the preset range, it indicates that the freshness of the silverfish does not meet the standard. The third valve is opened and the second valve is closed, allowing the silverfish to be discharged from the outlet under the action of water flow. When the proportion of the white area is less than the preset range, it indicates that the freshness of the silverfish meets the standard. Therefore, the second valve is opened and the third valve is closed, and the silverfish are transported to the next process through the second transport pipe.

[0012] Compared with existing technologies, the freshness of silverfish can be judged by changes in their body color, thereby eliminating silverfish that do not meet the freshness standards.

[0013] Furthermore, several screens are distributed along the height direction inside the feed hopper. The mesh area of ​​the screens decreases as the installation height decreases. The screens divide the feed hopper into several screening layers, and each screening layer is connected to a screener.

[0014] Beneficial effects: The sieve can separate silverfish of different sizes. Since only silverfish smaller than the mesh can pass through the sieve and enter the lower layers, the silverfish in each screening layer are similar in size due to the multiple sieves.

[0015] Furthermore, the side of the screen furthest from the feed hopper is lower than the side closest to the feed hopper.

[0016] Beneficial effects: The tilt of the filter allows the silverfish to move through segments not only by the water pressure generated by the water flow, but also by gravity.

[0017] Furthermore, the cavities inside both the first and second transport pipes are inverted triangles.

[0018] Beneficial effects: The inverted triangle has narrower sides that converge towards the center, which helps to keep the silverfish in the center of the pipe when it moves, reducing the risk of the silverfish tilting and causing blockages, and also reducing the probability of multiple silverfish entering the pipe at the same time.

[0019] Furthermore, a second water pipe is connected to the side wall of the first transport pipe.

[0020] Beneficial effects: The second water pipe can be connected to a clean water source, and the silverfish can be cleaned by supplying water through the second water pipe, thus making the silverfish cleaner and facilitating subsequent processing.

[0021] Furthermore, the third valve is a flap valve structure, and the flap valve of the third valve has several filter holes.

[0022] Beneficial effects: The flapping gate structure facilitates the opening of the gate to expel the silverfish, while also providing a carrier for the filter holes. The filter holes allow water supplied by the second water pipe to flow through and continuously rinse the silverfish. Furthermore, the silverfish are relatively large and will not be able to escape through the filter holes.

[0023] Furthermore, a laser photoelectric switch is installed inside the first transport pipe.

[0024] Beneficial effects: After the first valve is opened, the silverfish's body becomes translucent. The laser photoelectric switch can detect the light fluctuations when the silverfish enters the first transport tube, thereby confirming the number of silverfish entering and controlling the number of silverfish entering the first transport tube at one time.

[0025] Furthermore, a semiconductor cooling plate is provided on the side wall of the second transport pipe.

[0026] Beneficial effects: The semiconductor cooling chip can lower the temperature inside the second transport tube, thereby pre-cooling the silverfish during subsequent processing or storage to maintain their freshness. Attached Figure Description

[0033] Example 1

[0034] The basic implementation examples are as follows: Figure 1 To be continued Figure 4 As shown:

[0035] An automatic screening machine for processing silverfish includes a feeding tank 1 with an opening at the top, a first water pipe 2 connected to the top of the feeding tank 1, and a screener 3 connected to the feeding tank 1.

[0036] The screener 3 includes a first transport pipe 4, which is connected to the feed tank 1. The end of the first transport pipe 4 away from the feed tank 1 is connected to a freshness detector 5, and the end of the freshness detector 5 away from the first transport pipe 4 is connected to a second transport pipe 6.

[0037] The freshness detector 5 includes a housing 7. Inside the housing 7, a controller 8, a camera 9, a light source 11, and a power supply 10 are fixed with screws. The controller 8 is model YM-SMP01, the camera 9 is model OV5640, and the light source 11 is model DT0153. The camera 9 is located on the side of the housing 7 near the top of the first transport tube 4, and the light source 11 is located on the side of the housing 7 near the bottom of the first transport tube 4. Waterproof transparent plates 12 are glued and fixed to both the camera 9 and the light source 11. The light source 11 is a colored light source 11. A first valve 13 is provided inside the first transport tube 4, and a second valve 14 is provided at the connection between the second transport tube 6 and the freshness detector 5. A discharge port is provided on one side of the housing 7, and a third valve 15 is provided inside the discharge port.

[0038] The controller 8 is used to acquire images captured by the camera 9 and determine the area ratio of the white area in the image. When the area ratio of the white area is greater than a preset range, the third valve 15 is opened and the second valve 14 is closed. When the area ratio of the white area is less than the preset range, the second valve 14 is opened and the third valve 15 is closed.

[0039] The specific implementation process is as follows: Users can add silverfish through the feeding bucket 1, and the first water pipe 2 will continuously inject water into the feeding bucket 1 to maintain the water level in the feeding bucket 1.

[0040] Initially, the first valve 13 is closed. When the first valve 13 is opened, the feed bucket 1 will flow into the first transport pipe 4, carrying silverfish. After the silverfish enter, the first valve 13 is closed to prevent other silverfish from entering. Subsequently, the light source 11 will shine light from the bottom of the silverfish. Since the bodies of silverfish are translucent when alive, and within 1 hour after death, due to the disruption of the body's regulatory mechanisms, the proteins denature, gradually changing from translucent to snow-white. Therefore, the color under the colored light source 11 can reflect whether the silverfish is fresh.

[0041] When the proportion of the white area detected is greater than the preset range, it indicates that the freshness of the silverfish is not up to standard. The third valve 15 is opened and the second valve 14 is closed, allowing the silverfish to be discharged from the outlet under the action of water flow. When the proportion of the white area is less than the preset range, it indicates that the freshness of the silverfish meets the standard. Therefore, the second valve 14 is opened and the third valve 15 is closed, and the silverfish are transported to the next process through the second transport pipe 6.

[0042] This invention judges the freshness of silverfish by observing changes in their body color, thereby eliminating silverfish that do not meet the freshness standards and ensuring the quality of the processed raw materials.

[0043] Example 2

[0044] The difference from the above embodiment is that: a number of screens 16 are distributed in the feed barrel 1 along the height direction. The mesh area of ​​the screens 16 decreases as the installation height decreases. The screens 16 divide the feed barrel 1 into a number of screening layers, and each screening layer is connected to a screener 3.

[0045] The specific implementation process is as follows: The sieve 16 can screen silverfish of different sizes. Since only silverfish smaller than the mesh can pass through the sieve 16 and enter the lower layer, the silverfish in each screening layer are similar in size under the screening of multiple sieves 16.

[0046] Example 3

[0047] The difference from the above embodiment is that the side of the filter 3 furthest from the feed hopper 1 is lower than the side closest to the feed hopper 1.

[0048] The specific implementation process is as follows: The screen 3 is tilted so that the silverfish can move in segments not only by the water flow generated by water pressure, but also by gravity.

[0049] Example 4

[0050] The difference from the above embodiment is that the inner cavities of the first transport pipe 4 and the second transport pipe 6 are both inverted triangles.

[0051] The specific implementation process is as follows: The two sides of the inverted triangle are narrower and converge towards the center, which can constrain the position of the silverfish in the center of the pipe when it moves, reduce the silverfish tilting and causing pipe blockage, and reduce the probability of multiple silverfish entering the pipe at the same time.

[0052] Example 5

[0053] The difference from the above embodiment is that the side wall of the first transport pipe 4 is connected to the second water pipe 17.

[0054] The specific implementation process is as follows: The second water pipe 17 can be connected to a clean water source. Water is supplied through the second water pipe 17 to clean the silverfish, thereby making the silverfish cleaner and facilitating subsequent processing.

[0055] Example 6

[0056] The difference from the above embodiment is that the third valve 15 is a flap gate 18 structure, and the flap gate 18 of the third valve 15 has several filter holes 19.

[0057] The specific implementation process is as follows: The flap gate 18 structure facilitates opening the flap gate 18 to discharge the silverfish, and at the same time provides a carrier for the filter hole 19. The filter hole 19 allows the water supplied by the second water pipe 17 to be discharged through the filter hole 19, continuously rinsing the silverfish. Since the silverfish are relatively large, they will not escape through the filter hole 19.

[0058] Example 7

[0059] The difference from the above embodiment is that a laser photoelectric switch 20 is bonded and fixed inside the first transport tube 4. The model of the laser photoelectric switch 20 is E3F-20C1.

[0060] The specific implementation process is as follows: After the first valve 13 is opened, the silverfish body is semi-transparent. The laser photoelectric switch 20 can detect the light fluctuation when the silverfish enters the first transport tube 4, thereby confirming the number of silverfish entering and controlling the number of silverfish entering the first transport tube 4 at one time.

[0061] Example 8

[0062] The difference from the above embodiment is that a semiconductor cooling chip 21 is installed on the side wall of the second transport pipe 6. The semiconductor cooling chip 21 is of model TEC1-12706.

[0063] The specific implementation process is as follows: the semiconductor cooling chip 21 can reduce the temperature inside the second transport tube 6, thereby pre-cooling the silverfish in the subsequent processing or storage process to maintain the freshness of the silverfish.
