Oxygenation machine for macrobrachium rosenbergii seeds

Abstract

The invention relates to an oxygenation machine for macrobrachium rosenbergii seeds. The oxygenation machine comprises oxygenation boxes, a bearing table, first air outlet pipes and second air outletpipes, the oxygenation boxes are installed at the two ends of the top of the bearing table through bases, and hydraulic cylinders are vertically installed in the centers of the tops of the oxygenationboxes; rubber bowls are arranged at the bottoms of hydraulic rods, baffles are hinged to the two ends of the top in each second air outlet pipe through hinging shafts, and the first air outlet pipesare vertically installed at the two ends of the bottom of each second air outlet pipe; second springs are evenly installed on the inner side wall of a second sleeve, a connection rod is installed in the center, close to one side of each second spring, of a fixing ring, and a single chip microcomputer is vertically installed at the bottom of the outer side of each first air outlet pipe. According to the oxygenation machine for the macrobrachium rosenbergii seeds, when an oxygen sensor detects that after the oxygen content reaches a certain value, a signal is transmitted to the single chip microcomputer for controlling the hydraulic cylinders to be closed, and the situation is conveniently avoided that since the content of oxygen in a partial plastic bag is low, the macrobrachium rosenbergiiseeds die.

Description

technical field [0001] The invention relates to the technical field of Macrobrachium rosenbergii culture, in particular to an oxygenator for Macrobrachium rosenbergii seedlings. Background technique [0002] Macrobrachium rosenbergii, also known as Malaysian prawn and freshwater long-armed prawn, is a large freshwater prawn native to Southeast Asia. It has the advantages of fast growth, wide appetite, good meat quality and short breeding cycle. It has been used in my country since 1976. This shrimp was introduced in 2010, and it has been cultivated in more than ten provinces, municipalities and autonomous regions such as Guangdong, Guangxi, Hunan, Hubei, Jiangsu, Shanghai, and Zhejiang. The general yield can reach 70-100 kg per mu, which has achieved obvious economic benefits. Farmers Shrimp seedlings need to be purchased for breeding, and the shrimp seedlings need to be filled with an appropriate amount of oxygen in the plastic bag containing the seedlings before transportati...
