Loach fry hatching device

Abstract

The invention discloses a loach fry hatching device. The loach fry hatching device comprises a mounting rack, an upper barrel body and a lower barrel body, wherein both the upper barrel body and the lower barrel body are inverted conical structures, the upper barrel body is movably arranged on the mounting rack, an overflow groove is formed in the upper end of the upper barrel body, a screen mesh is arranged in the overflow groove and can completely cover an upper barrel body opening, a water outlet pipe is arranged at one end of the overflow groove and is connected with a water purifying device, a communicating pipe is arranged at the bottom of the lower barrel body and communicates with the lower barrel body, the lower end of the communicating pipe communicates with a fry outlet pipe and a water inlet pipe separately, the other end of the water inlet pipe communicates with the water purifying device, a fry outlet valve is arranged at the joint of the fry outlet pipe and the communicating pipe, a water inlet valve is arranged at the joint of the water inlet pipe and the communicating pipe, a concave circular baffle is arranged above the communicating pipe, a plurality of connecting bars are uniformly arranged around the circular baffle, and a plurality of aerators are uniformly arranged on the internal wall of the upper barrel body. According to the loach fry hatching device, through the cooperative action of the aerators and the circular baffle, the direction of water flow is changed, the amount of dissolved oxygen in barrels is increased, and the survival rate of hatching is increased.

Description

technical field [0001] The invention belongs to the technical field of automatic machinery, and in particular relates to a hatching device for loach seedlings. Background technique [0002] In the loach breeding process, it is generally necessary to lay eggs by the female loach, then transfer the eggs to the hatching bucket, and hatch them into seedlings under conditions such as appropriate temperature, pH value, light and dissolved oxygen. The requirements are high. During the breeding process, it is necessary to continuously feed clean water to ensure that the loach eggs can be evenly distributed in the hatching bucket and have a good ability to accept dissolved oxygen. The water inlet device at the bottom of the existing hatching bucket is directly connected to water. , usually due to excessive momentum, the fertilized eggs will be damaged, and the water flow caused will affect the even distribution of loach eggs. Now, a single oxygen-increasing head is installed on the i...

[0002] In the loach breeding process, it is generally necessary to lay eggs by the female loach, then transfer the eggs to the hatching bucket, and hatch them into seedlings under conditions such as appropriate temperature, pH value, light and dissolved oxygen. The requirements are high. During the breeding process, it is necessary to continuously feed clean water to ensure that the loach eggs can be evenly distributed in the hatching bucket and have a good ability to accept dissolved oxygen. The water inlet device at the bottom of the existing hatching bucket is directly connected to water. , usually due to excessive momentum, the fertilized eggs will be damaged, and the water flow caused will affect the even distribution of loach eggs. Now, a single oxygen-increasing head is installed on the inner wall of the hatching bucket, so that the dissolved oxygen in the hatching bucket is low and the distribution is uneven. Thereby affecting the success rate of loach seedling hatching
