Embodiment Construction
[0012] 1. If figure 1 , 2 Shown, there is an automatic counting device for fry, comprising camera 4 and computer 2 for data collection and processing installed on the counting platform 11, camera is installed on the camera frame 3 of the cantilever that can swing left and right through the telescopic frame up and down. After the camera obtains the fish fry pictures, use a specific program in the computer, such as using the gray scale evaluation method to process the number of fish fry in this batch, and then display the results on the display 1 or output them, and at the same time accumulate the results of each batch. The total amount of fry. The fry dispersing and conveying device is also installed on the counting platform, including a disc 5 fixedly installed on the platform, an impeller 10 is installed in the disc, the impeller shaft is vertically installed on the center of the disc, and 4 blades are fixed at intervals of 90°. on the axle. The blades are rectangular flat...

The invention provides an automatic fry counting device which comprises a disk (5), wherein the disk is coaxially provided with an impeller (10) consisting of at least three blades arranged equidistantly along the circumference; an impeller shaft is connected with an intermittent rotating drive mechanism (9), the each rotating angle of the impeller is equal to a central angle of a fanshaped cell; sealing mechanisms are arranged between the outer end and the lower edge of the blade in the impeller and between the side wall and the bottom of the disk; the disk is provided with a fry feeding region, a camera region and a fry discharging region, the fanshaped cells divided by the blade when the impeller shaft stops rotating are internally provided with fanshaped cells coincident with the fry feeding region, the camera region and the fry discharging region, and the bottom and / or side wall of the disk in which the fry discharging region is arranged are / is empty; and a camera (4), a computer (2) and a post-positioned fry collector (13) are arranged above the camera region, wherein the computer (2) is connected with the camera, and the post-positioned fry collector (13) is connected with the fry discharging region. Compared with the prior art, the automatic fry counting device ensures that fries can be continuously counted by batches under the drive of the impeller, thus the automatic fry counting device ensures the flow process and has high automation and high efficiency.
Description
technical field [0001] The invention relates to an automatic fry counting device, in particular to a fish fry grouping mechanism in the fry automatic counting device using computer technology, which belongs to the technical field of physical counting mechanisms. Background technique [0002] With the rapid development of the aquaculture industry, for example, the total number of various types of marine aquaculture cages in my country has exceeded 1 million, and the annual output is about 260,000 tons. The technology related to aquaculture has also been developed to a certain extent, but the scale of the aquaculture industry Still lagging behind. For example, the accurate counting of fish fry is the basis for scientific bait feeding, breeding density control, fry survival rate assessment, and fish fry purchase and sale. It is the fundamental guarantee for the implementation of aquaculture automation. However, due to the very small size of the seedlings, accurate counting of t...
