Embodiment 1

[0039] Such as figure 1 As shown, the special oscillating ovipositor for sea urchins includes an electric oscillating cylinder main body 1, the outer edge of the lower surface of the electric oscillating cylinder main body 1 is connected with a bracket base 3, and the center of the lower surface of the electric oscillating cylinder main body 1 is connected with an electric cycle washing collection Mechanism, support base 3 one side is fixedly connected with electric circulating water pump 11, and electric circulating water pump 11 is connected with electric circulation and scours collection mechanism, and the below of electric circulation and scours collection mechanism is provided with egg collection container 13. The main body of the electric vibrating cylinder 1 is used to place the sea urchins to be retrieved. The support base 3 is located directly below the main body of the electric vibrating cylinder 1. The support base 3 has the function of supporting the main body of th...

Embodiment 2

[0048] Such as Figure 2~7 As shown, in this embodiment, on the basis of Embodiment 1, the further optimization scheme is: the tail end of the elastic fixing piece 6 is connected to the upper end of the inner wall of the cylinder 4, and the head end of the elastic fixing piece 6 is connected to the inner wall of the cylinder 4 through the elastic material 9, The first end of the elastic fixing piece 6 is connected with a pressing tube 20 with an opening downward. The pressing tube 20 is surrounded by a tube wall 20b to form a tube inner space 20a. The thickness ratio H1:H2 of both ends of the tube wall 20b is 1:2.2~3.1. The elastic material 9 applies a downward pulling force to the elastic fixing sheet 6, so that the elastic fixing sheet 6 has the function of pressing down, and is used to fix the sea urchin. , to strengthen the fixation of the sea urchin, and the thickness ratio provided at the two ends of the tube wall 20b makes the space 20a in the tube have a slope that fit...

Embodiment 3

[0054] Such as Figure 2~7 As shown, the sea urchin-specific oscillating ovipositor, in the present embodiment, the optimal parameters of the ovipositor are set as follows:

[0055] 1) The power of the motor 8 is 30w, and the oscillation frequency is 200 times / min;

[0056] 2) The drainage flow rate of the electric circulating water pump 11 is 300 ml / min;

[0057] 3) The diameter of the electric vibration support 5 tray is 3cm;

[0058] 4) The thickness ratio H1:H2 at both ends of the tube wall 17b of the pressing tube 17 is preferably 1:2.5;

[0059] 5) The number of 15 short flushing pipes provided on the surface of the water guide pipe 10 is preferably 3, and the upward inclination angle of the short flushing pipes 15 is preferably 45°;

[0060] 6) The micro-current source 18 outputs a constant current of 3.8μA, and the current output frequency is 0.1Hz

[0061] The optimal parameter settings above can make the sea urchin-specific oscillating ovipositor achieve excellen...

Abstract

The invention provides a vibrating type egg taking device special for sea urchins and a use method thereof, and belongs to the technical field of sea urchin reproduction research. The egg taking device includes an electric vibrating cylinder body, the outer brim of the lower surface of the electric vibrating cylinder body is connected with a bracket base, the center of the lower surface of the electric vibrating cylinder body is connected with an electric circular flushing collection mechanism, an electric circulating water pump is fixedly connected to one side of the bracket base, and an eggcollecting vessel is arranged below the electric circular flushing collection mechanism. According to the egg taking device and the use method thereof, electric circular flushing connection of eggs isadopted, and under cooperation with electric vibration, egg discharge is facilitated; an egg taking method high in automation degree is achieved, intensive manual activity is replaced with an automatic device, the production cost is reduced, the efficiency of taking the eggs is high, and damage to the eggs is small.

Description

technical field [0001] The invention belongs to the technical field of sea urchin reproduction research, and in particular relates to a sea urchin-specific oscillating ovipositor and a using method thereof. Background technique [0002] Sea urchins belong to the class Echinoidea of ​​the door Echinodermata. At present, there are more than 850 species of sea urchins that have been discovered in the world, and there are more than 100 species in my country. However, most sea urchins are not edible. Horse dung sea urchins, purple sea urchins, white spines three-row sea urchins, sea hedgehogs, etc. Because sea urchin has high edible value, medicinal value and economic value, its economic species has also become fishery resources in developed countries such as the United States and Japan since the 1950s, and has been used as one of the main breeding species in recent years. [0003] Therefore, sea urchin breeding activities are becoming more and more frequent in my country and ev...
