Problems solved by technology

[0003] Although the current squid artificial spawning attachments can be used as squid spawning attachments to expand the area of ​​the spawning ground; but when picking eggs, the artificial spawning attachments need to be lifted by ropes, which is inconvenient to operate, and the artificial spawning attachments are not easy to operate. In the process of the rising of the attachment, it is impacted by sea water, and it is easy to cause the attached eggs attached to the artificial spawning attachment to fall off and lose

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments:

[0027] like figure 1 As shown, a sinking type squid egg attaching device includes: a lowering rope, a support frame, a protective box 2 arranged on the support frame, an egg attaching device 3, and a trigger release mechanism 4.

[0028] The support frame includes four vertical support rods 1, and the four vertical support rods are distributed at the four vertex positions of the rectangle. The outer side of the vertical support rod is provided with a support rod limit block 1.1.

[0029] The protective box is located above the limit block of the support rod, the lower end of the protective box is open, and the upper end of the protective box is closed. One end of the lowering rope is connected with the outer top surface of the protective box.

[0030] The egg-attaching device includes a lift plate 3.1 that can slide along the verti...

Abstract

The invention discloses a submerged squid egg attaching device, and aims to provide the submerged squid egg attaching device which facilitates egg collecting operation and can effectively avoid the problem that eggs attached to an egg attaching device fall off due to seawater impact in the lifting process of the egg attaching device. The submerged squid egg attaching device comprises a supporting frame, a protective box, the egg attaching device and a trigger releasing mechanism, wherein the supporting frame comprises a plurality of vertical supporting rods; supporting rod limiting blocks are arranged on the outer side surfaces of the vertical supporting rods; the protective box is arranged on the supporting frame; the lower end of the protective box is open; the egg attaching device comprises a lifting flat plate capable of sliding along the vertical supporting rods and positioned below the protective box, an upper supporting flat plate positioned above the lifting flat plate, a buoy connecting the lifting flat plate and the upper supporting flat plate, and a plurality of egg attaching ropes arranged between the lifting flat plate and the upper supporting flat plate; and the trigger releasing mechanism comprises a counterweight, a counterweight mounting rod hinged to the lower surface of the lifting flat plate, a mounting rod supporting mechanism and a trigger mechanism.

Description

technical field [0001] The invention relates to a device for attaching eggs, in particular to a device for attaching eggs to a submerged squid. Background technique [0002] The squid spawning habitat is very narrow, and the squid spawning has higher requirements on the attachments. The squid spawning attachments in the natural sea area are mainly corals, large seaweeds and artificial wastes. Among them, corals account for more than 60% and artificial wastes. It accounts for about 30%, and the base of seaweed accounts for about 10%; but with the destruction of the marine environment, the resources of spawning attachments, mainly gorgonian, in natural sea areas have been severely damaged, the number has dropped sharply, and the area of ​​traditional spawning grounds has plummeted. Therefore, placing artificial spawning attachments is widely used as a supplementary means in the process of squid resource proliferation. [0003] Although the current squid artificial spawning at...
