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-playing flow device and a flow-releasing method, aiming to provide a method that can prevent shellfish seedlings from being easily taken away by ocean currents during the process of being placed on the seabed, and distributed to areas that are not suitable for shellfish seedlings to attach and grow. In the seabed area, the bottom-playing device and method for reducing the survival rate of shellfish fry. It includes a bottom sowing cylinder with both ends closed, an isolation cylinder which is arranged in the bottom sowing cylinder and divides the inner cavity of the bottom sowing cylinder into an inner cavity and an outer cavity, and is arranged on the isolation cylinder and communicates with the inner cavity and the outer cavity. The release port of the bottom sowing cylinder, a number of discharge ports arranged on the outer surface of the bottom sowing cylinder and connected with the outer cavity, one-to-one corresponding shafts arranged at both ends of the bottom sowing cylinder, and the shaft sleeves arranged on the shaft for rotation, One-to-one corresponding to the running wheels arranged on the shaft, and the one-to-one corresponding walking trigger discharge mechanism with the discharge port.

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...
