A relay temporary culture device for croaker multiplication and release

Abstract

The invention discloses a spotted maigre enhancement and releasing relaying temporary raising device, and aims at providing a spotted maigre enhancement and releasing relaying temporary raising device capable of effectively solving the problems that in the existing oxygenating sealed transportation process, due to the fact that bubbles are gathered on the water surface to form a layer of foam, the water surface is isolated, and consequently the fry survival rate is low. The device comprises a fry temporary raising device. The fry temporary raising device comprises a temporary raising bucket, a blocking cover matched with the temporary raising barrel, and a foam self-cleaning device arranged in the temporary raising bucket, an opening is formed in the upper end of the temporary raising bucket, and the foam self-cleaning device comprises a conical guide sleeve, a gathering sleeve, a foam collecting sleeve and a floating block. The inner diameter of the conical guide sleeve is gradually increased from bottom to top, the gathering sleeve is connected with an upper end opening of the conical guide sleeve, the foam collecting sleeve is arranged on the upper portion of the conical guide sleeve, and the floating block is arranged on the outer side face of the foam collecting sleeve. The lower end of the foam collecting sleeve is in sealed connection with the upper surface of the conical guide sleeve, the gathering sleeve is located in the foam collecting sleeve, and the buoyancy of the floating block is larger than the gravity of the foam self-cleaning device.

Description

technical field [0001] The invention relates to a seed temporary cultivation device, in particular to a relay temporary cultivation device for croaker multiplication and release. Background technique [0002] When the yellow croaker fry is multiplied and released, it is necessary to transport the yellow croaker fry from the nursery to the release place. Oxygenated airtight transport method is one of the commonly used methods for transporting yellow croaker fry. Present oxygenated and sealed transport method is to adopt the transparent nylon bag oxygenation method to transport the described yellow croaker fry, transparent nylon bag every bag water 1 / 3 to 1 / 2, every bag puts the yellow croaker fry of one end quantity; Then the air in the transparent nylon bag is squeezed out, then filled with pure oxygen, tightly sealed, and transported by a transport vehicle. [0003] At present, this oxygenated and sealed transportation method will produce a certain amount of air bubbles d...

Problems solved by technology

[0008] The second purpose of the present invention on the basis of the first purpose is to provide a method that is not only easy to operate and high in operating efficiency, but also can effectively solve the problem of inconvenient fixing of transparent nylon bags and easy shaking during transportation, which affects the survival rate of seedlings. Problematic yellow croaker multiplication and release relay temporary culture device

[0009] The third purpose of the present invention on the basis of the first purpose is to provide a method that can effectively solve the problem that the gas in the temporary storage tank cannot be smoothly discharged from the gap between the sealing cover and the inner surface of the temporary storage tank, resulting in blockage. The cover cannot be moved into place under the action of its own weight, which leads to the problem that the device cannot work normally
