Technical Field

The invention relates to the field of fish fry breeding, in particular to a takifugu rubripes fry distributing device.

Background

In the process of breeding the fry, the sizes of the fry often greatly differ due to differences among different individuals in swimming speed, feeding capacity, metabolism and the like. In order to ensure that small-sized fries obtain enough bait for growth and prevent large-sized fries from biting or attacking the small-sized fries, the fries need to be separated after a period of culture, namely, the fries with different sizes are selected and then are respectively put into different culture ponds for culture. The present commonly used seedling device of dividing is the fish sieve, and this kind of device can only fall into big, two kinds of specifications with the fry to need constantly rock the fish sieve when dividing the fry, make in the gap of small dimension fry from the fish sieve bottom fall into the basin of below, not only waste time and energy, still can cause physical stimulation and damage to the fry at the seedling in-process of dividing simultaneously. The screened fry has small moving space and can not be taken out timely and conveniently. In addition, the fugu rubripes can quickly swallow water or air after being stimulated by the outside, so that the body volume is increased, and therefore, the conventional fish sieve is difficult to be used for separating the fries. Therefore, a new takifugu rubripes seedling separating device capable of solving the problems is needed.

Disclosure of Invention

The invention aims to solve the defects in the prior art and provides the takifugu rubripes seedling separating device which is simple in structure, ingenious in design, convenient to manufacture and install and free of damage to fish seedlings.

The technical solution of the invention is as follows: the utility model provides a fugu rubripes divides seedling device, includes basin 1, its characterized in that: a water channel 2 with a rectangular cross section is arranged in the water tank 1, a water pump 3 is arranged at one end of the water channel 2, the water pump 3 is controlled by a frequency converter 4, a flow guide device 5 is arranged at the outlet end of the water pump 3, the flow guide device 5 is composed of a plurality of flow guide pipes distributed in an array manner, a blocking net 6 is further arranged at one end, away from the water pump 3, of the water channel 2, a first grating 7 and a second grating 8 are arranged between the flow guide device 5 and the blocking net 6, the width of a gap of the first grating 7 is smaller than that of a gap of the second grating 8, the first grating 7 is slidably connected in a first slideway 9 arranged on the inner wall of the water channel 2, the second grating 8 is slidably connected in a second slideway 10 also arranged on the inner wall of the water channel 2, the area between the flow guide device 5 and the first grating 7 is a small-specification fish collecting area 11, and the area between the first grating 7 and the second grating 8 is a medium-specification fish collecting area 12, the area between the second grating 8 and the blocking net 6 is a large-size fish collecting area 13, a fish taking basket 14 with the same cross section area as that of the corresponding fish collecting area is placed at the bottom of each fish collecting area, and a lifting rope is connected to the fish taking basket 14.

Compared with the prior art, the invention has the following advantages:

this kind of structural style's fugu rubripes divides seedling device, its simple structure, design benefit, rationally distributed. Aiming at various problems of the traditional fry separating device (fish sieve) during fry separating operation, the special structure is designed. The device is provided with a long and straight water channel structure, and a water pump is adopted to form uniform and stable water flow in the water channel, so that spontaneous reverse flow swimming behavior of the fish fry of the takifugu rubripes is caused, the fish fry automatically pass through two grids with different gap widths arranged in the water channel, and the fish fry with three specifications, namely large, medium and small, can automatically stay in different fish collecting areas, and the aim of automatic fry separation is fulfilled; after the fry separation is finished, workers only need to take out the fish baskets in different fish collecting areas, and the operation of separating and collecting the fries with three specifications is achieved. The fry separating device can greatly accelerate the work efficiency of fry separation, and can not cause stimulation and damage of any form to the fry, thereby ensuring the survival rate of the fry in the subsequent breeding stage. Meanwhile, the manufacturing process is simple, the manufacturing cost is low, so that the novel LED lamp has various advantages, is particularly suitable for popularization and application in the field, and has a very wide market prospect.
