Problems solved by technology

[0003] The purpose of the present invention is to provide a method that can prevent shellfish seedlings from being easily taken away by ocean currents in the process of being placed on the seabed, and distributed to seabed areas that are not suitable for shellfish seedlings to attach and grow, thereby reducing the cost of shellfish seedlings. Bottom playback streaming device and streaming method for the problem of survival rate

specific Embodiment 1

[0043] Specific embodiment one: as figure 1 , figure 2 As shown, a bottom sowing flow device includes a bottom sowing cylinder 1 with both ends closed, an isolation cylinder 8 arranged in the bottom sowing cylinder and separating the inner cavity of the bottom sowing cylinder into an inner cavity 9.1 and an outer cavity 9.2, The release port 8.1, which is arranged on the isolation cylinder and communicates with the inner cavity and the outer cavity, and several discharge ports 2, which are arranged on the outer surface of the bottom sowing drum and communicate with the outer cavity, are arranged on the bottom sowing drum in one-to-one correspondence. Shafts 3 at both ends, shaft sleeves 4 rotatably arranged on the shaft, traveling wheels 5 arranged on the shaft in one-to-one correspondence, and walking trigger discharge mechanisms 6 corresponding to the discharge ports one-to-one. The shaft rod 3 is fixed at the end of the bottom sowing cylinder. The shaft sleeve is rotata...

specific Embodiment 2

[0056] Specific embodiment two: as image 3 Shown is a streaming method. The streaming method utilizes a bottom streaming device for streaming. For the specific structure of the bottom streaming device, refer to Embodiment 1.

[0057] This discharge method comprises the following steps:

[0058] First, the release ship 2a transports the bottom playback streaming device to the designated sea area for release, specifically, select a rocky bottom sea area and a sea area with a flat seabed surface, and transport the bottom playback device to the designated sea area for release by the release ship;

[0059] Place the shellfish fry to be released into the inner cavity;

[0060] Second, lower the bottom playing device to the bottom of the sea through the rope 1a, one end of the rope is connected to the connecting bracket, that is, the lower end of the rope is connected to the connecting bracket, and the other end of the rope is fixed on the release ship, that is, the upper end of th...

Abstract

The invention discloses a bottom sowing discharging device and a discharging method. According to the bottom sowing discharging device and the discharging method, the problems that shellfish fries arelikely to be taken away by ocean current in the process of being put on the seedbed, and cannot be distributed on the seabed area suitable for apposition growth of the shellfish fries, and consequently the survival rate of the shellfish fries is reduced can be avoided. The bottom sowing discharging device comprises a bottom sowing roller with two sealed ends, an isolating barrel, a releasing opening, a plurality of discharging openings, shaft rods, shaft sleeves, walking wheels and walking triggering discharging mechanisms. The isolating barrel is arranged in the bottom sowing roller and separates an inner cavity of the bottom sowing roller into an inner cavity and an outer cavity, the releasing opening is formed in the isolating barrel and is communicated with the inner cavity and the outer cavity, the discharging openings are formed in the outer side face of the bottom sowing roller and communicated with the outer cavity, the shaft rods are arranged at the two ends of the bottom sowing roller are in one-to-one correspondence, the shaft sleeves are rotationally arranged on the shaft rods, the waling wheels are arranged on the shafts rods and are in one-to-one correspondence withthe shaft rods, and the walking triggering discharging mechanisms are in one-to-one correspondence with the discharging openings.

Description

technical field [0001] The invention relates to the field of releasing shellfish fry, in particular to a bottom playing device and a releasing method. Background technique [0002] Artificial shellfish ecological restoration means that shellfish are released into natural marine waters where shellfish resources have declined after artificial breeding and breeding, so that the natural population of shellfish can be restored. At present, the general method of artificial shellfish ecological restoration is to pack the seedlings, transport them to the release sea area by a transport ship, and then manually sow the seedlings in a certain sea area. Because shellfish seedlings are easily taken away by ocean currents during the process of being placed on the seabed, they are randomly distributed everywhere on the seabed, and many seabeds are not suitable for the attachment and growth of shellfish seedlings (such as muddy bottom sea areas). Most of the shellfish seedlings cannot surv...
