A shrimp egg hatching and pushing device

Abstract

The invention provides a shrimp egg incubation egg stacking device. The shrimp egg incubation egg stacking device comprises a pool body, a crane frame, a driving motor, a fixed pulley and a traction steel wire, the pool body is provided with a first side wall and a third side wall which are parallel to each other, and the crane frame crosses on the first side wall and the third side wall; the pool body further comprises a second side wall and a fourth side wall opposite to the second side wall, wherein the driving motor is fixed at the upper end of the second side wall, and the fixed pulley is fixed at the upper end of the fourth side wall; one side of the traction steel wire is fixed to the side portion, close to the fixed pulley, of the crane frame, and the other end of the traction steel wire penetrates through the fixed pulley and winds on a helix drum of the driving motor for multiple circles to be fixed to the other side of the crane frame; stirring devices are arranged below the crane frame, and the driving motor drives the crane frame to slide along the first side wall and the third side wall by driving the traction steel wire. According to the shrimp egg incubation egg stacking device, water is stirred regularly and directionally, so that space redistribution of stacked shrimp eggs and uniformity of water oxygen are achieved, and the problems of bottom oxygen deficit and dead egg stacking of ordinary airflow aerobic incubation are greatly improved.

Description

technical field [0001] The invention relates to a shrimp egg hatching technology, in particular to a shrimp egg hatching and pushing device. Background technique [0002] Due to the high economic value of shrimp, the market demand is increasing. Its artificial breeding and farming have always been the key factors restricting the further expansion of its industrialization and reducing production costs, and the key technology of the two is shrimp. The successful hatching of eggs and the hatching of shrimp eggs have always been an important step in the economical shrimp breeding process. The hatching rate is a restrictive factor for the cost of seedlings and the final profit. However, the existing methods rely on water to naturally pile up shrimp eggs. It is easy to cause long-term deposition of shrimp eggs at the bottom of the shrimp pond, resulting in hatching failure due to lack of oxygen, thereby reducing the hatching rate.

[0002] Due to the high economic value of shrimp, the market demand is increasing. Its artificial breeding and farming have always been the key factors restricting the further expansion of its industrialization and reducing production costs, and the key technology of the two is shrimp. The successful hatching of eggs and the hatching of shrimp eggs have always been an important step in the economical shrimp breeding process. The hatching rate is a restrictive factor for the cost of seedlings and the final profit. However, the existing methods rely on water to naturally pile up shrimp eggs. It is easy to cause long-term deposition of shrimp eggs at the bottom of the shrimp pond, resulting in hatching failure due to lack of oxygen, thereby reducing the hatching rate

[0003] In recent years, more and more people try to improve the oxygen content of the water body by means of water impact and inflatable turning, and solve the local hypoxia problem caused by the long-term accumulation of shrimp eggs. One method commonly used in the prior art is to use a The shrimp egg hatching device uses the air pump to drive the sand head inflating device connected to the air pump to stir the water flow in the shrimp egg hatching device, but simply rely on the air pump to inflate the water flow, and the sand head inflating is very easy in the early stage of shrimp hatching. Shrimp eggs are damaged, and the aeration efficiency is low, the oxygen content in the water body is uneven, and the bottom water body is basically stable, often causing hypoxia at the bottom, which seriously affects the hatching rate. In addition, the shrimp egg hatching device should not be too large, otherwise the water body will be hypoxic It will be more serious. If a large number of seedlings are required, a large number of devices are required to hatch at the same time, which increases the cost and labor.

Another commonly used method is to build an inverted circular shrimp egg hatching tank, realize the circular movement of the water body and supplement oxygen through the pumping device at the water inlet, and use the water body movement to realize the turning of the shrimp eggs to achieve the purpose of hatching. However, this method is likely to cause severe hypoxia at the bottom. Because the bottom of the pool is flat, there are dead corners of water flow, and shrimp eggs are easy to accumulate here, and the lower water body is prone to hypoxia, resulting in dead eggs.

[0004] The two commonly used shrimp egg hatching methods can not solve the problem of uneven oxygen and bottom layer hypoxia after the shrimp eggs are accumulated.
