Problems solved by technology
The most common method of dividing fish is manual selection. After fish fry to be divided are uniformly fished out, many people manually select them one by one from the long tank with water. Although this method is precise, it is inefficient, labor-intensive, and labor High cost, not suitable for efficient factory output requirements

Embodiment Construction
[0014] The implementation of the present invention will be described in further detail below in conjunction with the accompanying drawings. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.
[0015] Embrace type fish separator, such as figure 1 As shown, a water pump 9 is included, and a battery 10 for providing power for the water pump is sealed and installed in the water pump. A water suction pipe 7 is fixedly installed at the suction port of the water pump, and a control water pump is installed outside the horizontal initial end of the water suction pipe. The switch button 8 in the working state, the left side of the horizontal initial end of the suction pipe extends obliquely downward to form the inclined pipe 5 of the suction pipe, and the inclined pipe 3 extending along the inclined pipe of the suction pipe is inserted in the lower opening of the inclined pipe of the suction pipe. The inclined...

The invention relates to an embraced type fish fry classifier which comprises a water suction pump, wherein a battery is mounted inside the water suction pump in a sealed manner; a water suction tube is fixedly mounted at the water suction end of the water suction pump; a switch button is mounted on the outer side of the water suction tube; the left side of the water suction tube extends downwards in an inclined manner to form an inclined water suction tube; an extended inclined water suction tube which slides along the inclined water suction tube is inserted into the lower opening of the inclined water suction tube; the inclined water suction tube is locked with or dissociated from the extended inclined water suction tube through a locking ring at the lower end of the inclined water suction tube; after extending downwards, the extended inclined water suction tube is bent horizontally to form a horizontal end tube; a filtering net hole is screwed at the opening of the horizontal end tube; a water outlet tube is fixedly mounted at the water outlet end of the water suction pump; and a water discharge hose is mounted at an end hole of the water outlet tube. Due to the embraced water suction device, fine fish fry classification is achieved, and due to intermittent operation, net holes can be prevented from being blocked, large fish injury can be also avoided, the time and the labor are saved, and the efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of aquaculture equipment, in particular to an embrace-type fish seedling separator. Background technique [0002] In aquaculture, splitting fry is an essential step in daily management. Due to the differences in the growth of individual fry, the same batch of fry may have different specifications. Small fish and big fish live together. If the seedlings are not separated in time, the big fish will eat the small fish, resulting in a decrease in fry output. In addition, when fish fry are commercialized and sold, it is also necessary to maintain uniform specifications for sale as much as possible. The most common method of dividing fish is manual selection. After fish fry to be divided are uniformly fished out, many people manually select them one by one from the long tank with water. Although this method is precise, it is inefficient, labor-intensive, and labor The cost is high, and it is not suitable for ef...
