Fish and shrimp fry counting machine

Abstract

The invention discloses a fry and shrimp counting machine which comprises a communication pipe (1), a transitional tank (2), an annular transmission belt (3), a waterwheel and a camera (5). A fry and shrimp breeding tank is communicated with the transitional tank (2) through the communication pipe (1), a plurality of fry and shrimp hoppers (4) are arranged on the transmission belt (3), water containing fries and shrimps in the transitional tank (2) is conveyed into the fry and shrimp hoppers (4) at the front end of the transmission belt (3) by the waterwheel, and the camera (5) is connected with a process and positioned above the transmission belt (3). The fry and shrimp counting machine can greatly accelerate counting and further can greatly improve counting accuracy.

Description

technical field [0001] The invention relates to the technical field of fishery machinery, in particular to a fish and shrimp fry counting machine. Background technique [0002] When fish and shrimp fry farming enterprises sell fish and shrimp fry, they need to count the number of sold fish and shrimp fry. Obviously, it is difficult to count the massive and tiny fish and shrimp fry by manual counting. In actual production and operation, the seller usually scoops a spoonful of hairtail shrimp water from the breeding pond where fish and shrimp fry are raised, and then counts the number of fish and shrimp fry in the spoonful, and then multiplies the number of spoonfuls sold. This is used to obtain an approximation of the fry sold. The above-mentioned counting method is naturally very low in accuracy and has a large error. [0003] And in modern aquaculture enterprises, there is also a counting machine with the following principle, that is, a seedling tube is set on the breedi...

Problems solved by technology

Although the counting results of the above-mentioned counters are accurate, there are still the following defects: first, the counters need fish and shrimp seedlings to pass through the emergence tube one by one, so the counting efficiency is very low and the speed is very slow, which cannot meet the needs of large-scale counting and selling of fish and shrimps. The actual needs of seedlings are not practical at all; and the actual size of the emergence tube is difficult to grasp. If the pipeline is too thin, it is easy to be blocked, which will affect its normal counting, but if the pipeline design is too thick, fish and shrimp fry will easily pass through in pairs or multiples. , affecting the accuracy of the calculation structure, and the fish and shrimp seedlings in the actual operation process are often large and small, so it is difficult to find a suitable size of the emergence tube

In summary, this kind of equipment is slow, easy to jam, and the results are not very accurate, so it is almost useless
