Embodiment Construction

[0024] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0025] Such as figure 1 As shown, a snail breeding device based on the bottom sowing method includes a base 1, a floating ball 7, a pre-tightening mechanism 9, a trigger release mechanism 8, and a lever arranged on the base through the rotation of the horizontal shaft 2. 3. The lever limit stopper arranged on the base and located above the lever 5, the counterweight slidingly sleeved on the lever 4, the counterweight limit stopper arranged at one end of the lever 4.1, the counterweight set on the lever The temporary raising box 6 with the upper end open and the cover plate 6.1 which is arranged on the base and is used to cover the upper end opening of the temporary raising box. Float is connected with the upper surface middle part of base by connecting rope 7.1. The cover plate is located above the holding box. The holding box is a metal cage...

Abstract

The invention discloses a conch culture and proliferation device based on bottom sowing. The purpose is to provide the conch culture and proliferation device based on bottom sowing which can effectively avoid the problem that conch fry is likely to be taken away by an ocean current before attachment is achieved and distributed to a seabed area not suitable for attached growth of the conch fry, so that the survival rate of the conch fry is lowered. The device comprises a base, a lever arranged on the base in a rotational mode through a horizontal shaft lever, a lever limiting stop bar arranged on the base and located above the lever, a balancing weight arranged on the lever in a sliding and sleeving mode, a balancing weight limiting stop block arranged at one end of the lever, a temporary culture box with the open upper end arranged on the lever and a cover plate which is arranged on the base and used for sealing and sheltering the upper end opening of the temporary culture box. The balancing weight and the temporary culture box are located on the opposite sides of the horizontal shaft lever, the balancing weight limiting stop block and the balancing weight are located on the same side of the horizontal shaft lever, and the lever limiting stop bar and the temporary culture box are located on the same side of the horizontal shaft lever.

Description

technical field [0001] The invention relates to a device for increasing cultivation, in particular to a device for increasing cultivation of snail shellfish based on bottom sowing. Background technique [0002] Artificial snail shellfish ecological restoration means that snail shellfish are released into natural marine waters where snail shellfish resources have declined after artificial breeding and seedling cultivation, so that the natural population of snail shellfish can be restored. At present, the general method of artificial ecological restoration of snail shellfish is to pack the seedlings, transport them to the release sea area by transport ship, and then manually sow the seedlings in a certain sea area. Since it takes about a week for snail seedlings to attach to the seabed, it is easy to be taken away by ocean currents and randomly distributed to various parts of the seabed. However, many seabeds are not suitable for the attachment and growth of snail-like seedli...
