Automatic packaging method and device for fry

Abstract

The invention discloses an automatic packaging method for fry. A safe low-voltage power source and a low-voltage starting switch control a pump to output power, the water outlet flow of the pump is automatically metered, and the water inlet quantity and oxygenation and bagging time of fry bags are accurately controlled. The method comprises the following steps of: pumping water from a pond by using the pump; making the water enter a filter bag through a water pipe and filling the water in the fry bags through a hopper until the required volume is met; continuously conveying the fry bags by using a conveyor belt to an oxygenation machine for oxygenation, and sealing the fry bags; and boxing and transporting. The automatic packaging method for the fry is safe and reliable; and the equipmenthas a simple structure, the original water fetching post can be eliminated, the post coordination contradiction in the quick operating process is avoided, the workers are reduced, the packaging speedis improved by more than 2 times, the error rate of each bag of fry is reduced, the package weight accuracy is over 95 percent and the survival rate of the fry is ensured.

Description

technical field [0001] The invention relates to fishery packaging machinery, in particular to a method and device for intelligent packaging of aquatic seedlings. Background technique [0002] At present, there are hundreds of billions of fish fry and shrimp fry that need to be transported over long distances in China every year. Generally speaking, there are two transportation methods: one is to use the open fish bucket method, which can only be used for short-distance transportation, In order to be able to transport over long distances, someone has invented a fish barrel or fish box that can be oxygenated, such as the patent invented by Wang Haibo of Xikou Town, Longyou County, Zhejiang Province: an oxygen-chargeable fish barrel (application number is 200520116677), published A container is provided, aiming to provide an oxygen-inflatable fish tank for packaging aquatic products. The fish bucket includes a bucket body and a bucket cover, and an air inlet and water inlet ar...

Yet the present inventor finds, there is certain shortcoming in above patent, and the one, because the volume of fish barrel is relatively large and heavy, so, this device still fails to obtain good promotion, when needing long-distance transportation, people are to adopt sealed plastic Bag method, this method can be placed in cartons or wooden boxes, and shipped by air, rail, or automobile. It has the advantages of small size, high shipping density, convenient loading and unloading, and high survival rate, and has been favored by everyone. Second, the above patents are not suitable for the transportation of aquatic seedlings. Because the value of aquatic seedlings is higher than that of finished aquatic products, and they are delicate and weak, they have become the bottleneck of transportation. At present, due to the time of bagging It is longer, so it greatly restricts the transportation method of sealed plastic bags, because the longer the packaging and transportation time, the lower the survival rate of seedlings, and time is life. So, how to shorten the packaging time and reduce transportation costs has always been a concern of the industry. The problem
