Description

Technical Field

[0001] The utility model relates to the technical field of shellfish property detection devices, in particular to a device for rapidly and non-destructively detecting shellfish body dimensions and adductor muscle properties. Background Art

[0002] Shellfish, as one of the important aquatic products, accounts for more than 70% of my country's marine aquaculture output. With the maturity of shellfish artificial breeding and seedling raising technology and the development of large-scale aquaculture industry, the breeding cycle of shellfish, that is, the growth rate, has gradually become a concern of farmers. Therefore, relevant research on the growth traits of shellfish body size has become more and more urgent. In addition, the adductor muscle of shellfish, as one of the eight delicacies of seafood, is often widely consumed in fresh, frozen and dried forms. Its weight and its proportion to the total body weight are also the most important growth economic characteristics in scallop farming.

[0003] The rate of increase in body size and the size of the adductor muscle are important criteria for measuring the quality of the economic traits of shellfish growth. When evaluating body size traits, such as shell height and shell length, scallops need to be manually measured and recorded one by one with a vernier caliper. This process is labor-intensive and cannot guarantee the accuracy of the data. Importantly, when evaluating the muscle characteristics of scallops, traditional dissection methods can lead to the death of scallops and loss of reproductive ability, which has a certain adverse impact on aquaculture production applications and the selection of excellent broodstock.

[0007] Preferably, the X-ray light source can be set to a voltage and current for clear imaging of the shells and adductor muscles of shellfish as required; by setting the X-ray light source parameters, for example, a high voltage value of 120 (KV) and a current of 800 μA, which are conducive to imaging of scallop shells and adductor muscles, clear capture of the shells and adductor muscle contours of shellfish is achieved.

[0008] Preferably, the activation and deactivation of the X-ray light source is regulated by a trigger, and the trigger is fixedly arranged on one side of the X-ray detection box to obtain the position of the object to be inspected and control the X-ray irradiation time.

[0009] Preferably, the conveyor includes an electric roller, a load-bearing plate, and a leather belt sleeved between the electric roller and the load-bearing plate. The conveyor is controlled by a conveyor control key, and the electric roller can rotate forward, reverse, and stop. The electric roller of the conveyor drives the leather belt to bring the shellfish under the X-ray light source of the X-ray detection box for shooting.

[0011] Preferably, the X-ray panel collector can be set to the Exposure Time (irradiation time) and Delay Time (delay time) for clear imaging of the shell and adductor muscle of the shellfish according to the needs. The center position of the X-ray panel collector should be aligned with the center position of the X-ray light source emission port, and the distance between the center position of the X-ray panel collector and the center position of the X-ray light source emission port is 40-50cm. By setting the parameters of the X-ray panel collector, for example, the exposure time of 1500ms, the delay time of 1000ms, the integration time of 100ms, and the double exposure, which are conducive to the imaging of the scallop shell and adductor muscle, the clear shooting of the shell and adductor muscle contour of the shellfish is achieved.

[0012] Preferably, a lead curtain is fixedly installed on the outside of the X-ray detection box to prevent X-rays from leaking outward.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 4 , the utility model provides a technical solution:

[0023] A device for rapidly and non-destructively detecting the body size and adductor muscle properties of shellfish comprises an X-ray light source 1, a conveyor 2, an X-ray panel collector 3, an image analyzer 4 and an object to be inspected; the X-ray light source 1 and the X-ray panel collector 3 are arranged inside an X-ray detection box 5; the X-ray light source 1 is located above the conveyor 2 and is fixedly arranged on the top of the X-ray detection box 5; the X-ray panel collector 3 is fixedly arranged below the conveyor 2; the conveyor 2 horizontally passes through the opposite side walls of the X-ray detection box 5 and is fixedly connected to a base 6; the image analyzer 4 is connected to the X-ray panel collector 3 to generate an image and calculate the body size and adductor muscle properties of the detection object.

[0024] In one embodiment, the X-ray light source 1 can be set to a voltage and current for clear imaging of the shell and adductor muscle of the shellfish according to the requirements. The parameters of the X-ray light source 1 can be adjusted through the ray source setting button, and then the application is saved and exited. By setting the parameters of the X-ray light source 1, for example, the high voltage value of 120 (KV) and the current of 800 μA, which are conducive to the imaging of the scallop shell and adductor muscle, a clear shooting of the shell and adductor muscle contour of the shellfish is achieved.

[0025] In one embodiment, the start and shut down of the X-ray light source 1 is regulated by a trigger 7, and the trigger 7 is fixedly arranged inside the X-ray detection box 5 near the side where the object to be inspected enters, so as to obtain the position of the object to be inspected and control the X-ray irradiation time. There is a pair of triggers 7 on the side where the object to be inspected enters, and when a signal that the shellfish enters a specific position is detected, the X-ray is turned on. When the image analyzer 4 obtains the image of the shell and the adductor muscle, the system turns off the X-ray. The trigger 7 allows the shellfish to be exposed to the shortest amount of X-rays, so that a low dose of radiation can still produce high-quality imaging.

[0026] In one embodiment, the conveyor 2 is mainly composed of an electric roller 21, a load-bearing plate 22, a driven roller 23 and a leather belt 24 sleeved between the electric roller and the load-bearing plate. The conveyor 2 is controlled by a conveyor control key, which can control the forward rotation, reverse rotation and stop rotation of the electric roller 21. The leather belt 24 is made of PU material and is seamless and integral, which has reduced the influence of X-rays to a minimum. The load-bearing plate 22 is an SPCC cold-rolled plate, which has been completely avoided on the X-ray rays and does not affect the imaging by default. The electric roller 21 of the conveyor 2 drives the leather belt to bring the shellfish under the X-ray light source of the X-ray detection box for shooting. In this process, the shellfish is smoothly transported on the conveyor belt, which minimizes the stress response in the measurement of the shellfish body size. The forward, reverse and stop rotation of the electric roller enables the reshooting of unqualified pictures.

[0027] In one embodiment, the conveyor length extends 30 cm beyond the two opposite side walls of the X-ray detection box 5, and the speed of the electric roller 21 is 25 cm / s, so as to facilitate the placement and rapid transmission of the items to be inspected. The 30 cm extension of the conveyor length beyond the two opposite side walls of the X-ray detection box 5 and the 50 cm width provide a suitable platform for the placement of shellfish. For example, scallops are placed in a 3×3 layout, which is more conducive to efficient shooting. According to the 140 cm total length of the conveyor 2 and the speed of the electric roller 21, the device can achieve a measurement speed of 30 pieces / minute, realizing the rapid detection of shellfish body size and adductor muscle characteristics at the same time.

The center position of the X-ray panel collector 3 should be aligned with the center position of the emission port of the X-ray light source 1, and the distance between the center position of the X-ray panel collector 3 and the center position of the emission port of the X-ray light source 1 is 40-50cm. By setting the parameters of the X-ray panel collector 3, such as the exposure time of 1500ms, the delay time of 1000ms, the integration time of 100ms, and the double exposure, which are conducive to the imaging of the shell and adductor muscle of the scallop, the clear shooting of the shell and adductor muscle contour of the shellfish is achieved.

[0029] In one embodiment, a lead curtain 51 for preventing X-rays from leaking outward is fixedly installed on the outside of the X-ray detection box 5. The lead curtains 51 installed on opposite sides of the X-ray detection box 5 block the X-rays inside the X-ray detection box 5, thereby preventing the X-rays from leaking outward.

[0030] In one embodiment, the image analyzer 4 includes image generation and processing software, a display screen 41, a keyboard 42, a mouse 43, and a host 44. The image analyzer can obtain clear images of shells and adductor muscles. The image analyzer 4 can calculate and analyze the body size and adductor muscle characteristics of the detected object. All images obtained by the image analyzer 4 are automatically saved to the specified path and can be searched and called out through the history records of the "File Management" button. After obtaining the shellfish scanned image, you can click the image processing area option on the image analyzer 4 software interface to perform image interpretation. Similarly, you can also perform image interpretation through the image processing button on the device keyboard 42. The image analyzer 4 can observe the previous / next scanned image through the image selection function, and zoom in and observe a specific part of the image through the zoom function. The image analyzer 4 has functions such as contrast adjustment, enhancement, high penetration enhancement, brightening, and image reflection. The image analyzer 4 can achieve the acquisition of clear shell and adductor muscle contours by adjusting the contrast and brightness of the X-ray image and other functions. The image processing software (ImageJ software) was used to outline the contours of the shell and adductor muscle in the above-obtained image, and the ROI manager was used to measure and record the data. Length1 was set as the shell height, Length2 was set as the shell length, Area1 was set as the shell area, and Area2 was set as the adductor muscle area. The unit was mm, thus achieving the simultaneous detection and analysis of the body size of shellfish and the traits of the adductor muscle.
