Description

Technical Field

[0001] The utility model belongs to the field of biotechnology, and particularly relates to a rapid screening device for red-shelled clams. Background Art

[0002] 3-4% of wild clams have red shells. These clams are high in carotenoids, which promote growth and stress resistance. They are also highly valued and have a delicious texture. In the Japanese market, red clams fetch three to four times the price of regular clams. Fishermen can eat them raw at sea to quench their hunger and thirst, and they are also more delicious and less prone to diarrhea. Consequently, red clams are increasingly becoming a popular choice in the clam processing industry. However, during the farming process, they often mix with other clams of different shell colors, necessitating screening. Currently, the most common method for screening red clams is to visually identify the shell color and manually sort them, which is inefficient and difficult to guarantee due to the varying depths of the shell texture.

[0019] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1As shown, an embodiment of the present invention provides a rapid screening device for red-shelled clams, comprising a conveying assembly, a color detection assembly, and a screening mechanism. The conveying assembly includes an entrance bin 1 and a first guide groove 2. The entrance bin 1 has an opening located at the top of the device and communicates with the first guide groove 2. A sponge is provided inside the entrance bin 1 to slow the clams' descent and prevent them from being damaged. A limit clamp 3 is symmetrically provided at the entrance of the first guide groove 2, and a double-ended bayonet 4 is provided within the first guide groove 2. The limit clamp 3 is used to feed the clams into the color detection assembly in a single sorting manner, and the double-ended bayonet 4 serves to secure the clams. The outlet of the first guide groove 2 is communicated with the color detection assembly.

[0021] The color detection assembly includes a color sensor 5, a data processor 7, and a second guide groove 6. The entrance of the second guide groove 6 is connected to the outlet of the first guide groove 2, and the outlet of the second guide groove 6 is connected to the screening mechanism. Multiple color sensors 5 are arranged in the second guide groove 6 and are connected to the data processor 7 signal. A limited bayonet 9 is provided in the second guide groove 6 to fix the clam, making it convenient for the color sensor 5 to distinguish the color of the clam. The limited bayonet 9 is arranged below the color sensor 5. In the present embodiment, the color sensor 5 is provided with three, respectively arranged on both sides and one side of the bayonet on the limited bayonet 9, respectively measuring the color parameters of the lower edge of the shield surface, the lower edge of the small moon surface, and the ventral edge of the clam shell color, thereby increasing the screening accuracy. The color detection assembly also includes an indicator light 8, which is connected to the data processor 7.

[0022] The screening mechanism includes a movable push plate 10 and a temporary storage bin 12. The movable push plate 10 is provided with two holes 11. A slide is provided below the hole 11, and the slide is connected to the temporary storage bin 12. The screening mechanism also includes a servo motor 13 and a push rod 14. The push rod 14 is connected to the movable push plate 10. The output end of the servo motor 13 is fixedly connected to the push rod 14. The servo motor 13 is connected to the data processor 7 by signal. After the data processor 7 distinguishes the color of the clams, the result is transmitted to the servo motor 13. The servo motor 13 drives the push rod 14 to push or retract the movable push plate, thereby selectively sending the clams to different temporary storage bins.

[0023] The working principle of the utility model is as follows: first, the clams to be screened are poured into the entrance bin, the falling speed of the clams is buffered by a sponge, and the position of the clams is standardized by a limit clamp at the entrance of the first guide groove and a double-end bayonet provided in the first guide groove, so as to facilitate subsequent color discrimination; when the clams enter the second guide groove, the limit bayonet restricts the clams from continuing to slide down, and the color of the clams is discriminated by three color sensors, and the color parameters of the lower edge of the shield surface, the lower edge of the small moon surface, and the ventral edge of the clam shell with stable color are measured. After the measurement is completed, the color The sensor transmits the collected redness and greenness values ​​(a*) to the data processor, which obtains the redness and greenness values ​​(a*) and sends them to the indicator light and servo motor. When the redness and greenness values ​​(a*) are greater than zero, the indicator light is green; when the redness and greenness values ​​(a*) are less than zero, the indicator light is red. When all three traffic lights are green, the push plate does not move, and the clams fall into the holes on the left, which are the red-shelled clams obtained by the rapid screening of the device; if any of the three traffic lights is red, the push plate moves to the left, and the clams fall into the holes on the right, which are clams of other shell colors.

[0024] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
