Embodiment 1

[0043] see Figure 1-6 , a mechanized harvesting device for longline cultured oysters, the harvesting device is fixedly arranged on a floating boat, and includes a first rocker conveyor, a second rocker conveyor, a transfer conveyor, a lifting device, and a guide wheel device; The first rocker conveyor is fixed on the side of the pontoon, and the front end can swing around the rear elevation; the second rocker conveyor is fixed behind the first rocker conveyor, and the rear end can swing around the front end. The facade swings; the first and second rocker conveyors are connected by a transfer conveyor; the lifting device is used to hook the longline to the low-position guide wheel device or the high-position guide wheel device; the first The rocker conveyor swings to an appropriate angle to accept the vertical rope. The guide wheel device drives the long rope to move slowly. The vertical rope is separated from the longline; the surface of the conveyor belt of the first convey...

Embodiment 2

[0050] see Figure 7 , 9 , 11. The difference between this embodiment and Embodiment 1 is that the guide wheel device also includes a high-position guide wheel device, and the lifting device hangs the longline on the high-position guide wheel device, so that the longline not only breaks away from the water surface, but also Make the vertical rope completely out of the water. When the shells are loosely attached and easy to fall off, harvest at a high position, which is convenient for the crew to monitor and improve the ability to respond to emergencies;

Embodiment 3

[0052] The difference between this embodiment and Embodiments 1 and 2 is that it also includes a lifting device, the guide wheel device is arranged on the lifting device, and the lifting device can raise the guide wheel device to an appropriate height, Thereby, the height of the guide wheel device can be adjusted freely, which is convenient for the crew to observe or operate.

[0053] In this embodiment, the mechanized harvesting equipment for longline cultured oysters is used for salvaging artificially cultured scallops.

[0054] During specific implementation, the following steps are included:

[0055] A) The pontoon travels to the side of the longline so that the position of the longline corresponds to the side;

Abstract

The invention relates to long line culture oyster mechanized harvesting equipment. A harvesting device is fixedly arranged on a floating boat; a first rocker arm conveying machine is fixedly arranged at the broadside of the floating boat, and the front end can swing around the vertical surface of the back end; a second rocker arm conveying machine is fixedly arranged behind the first rocker arm conveying machine, and the back end can swing around the vertical surface of the front end; a lifting device is used for hooking a long line to a position above a low-position guide wheel device or a high-position guide wheel device; when the first rocker arm conveying machine swings to a proper angle, the long line is carried; the guide wheel device drives the long line to slowly move; the first rocker arm conveying machine drives a vertical line and oysters fixed on the line to be obliquely, upwards and slowly conveyed; at the same time, the vertical line and the long line are gradually separated; the second rocker arm conveying machine continuously and backwards conveys the salvaged vertical line and the oysters fixed on the vertical line. The rocker arm conveying machines are used for carrying and conveying the oysters fixed on the vertical line; the labor intensity of seaman operation is reduced; the collecting and the conveying of the oysters are simultaneously completed; the oyster collecting flow process is simplified.

Description

technical field [0001] The invention relates to a harvesting method and equipment for longline cultured oysters, and belongs to the technical field of harvesting artificially cultured oysters. Background technique [0002] The oyster longline culture method generally needs to use longlines, floating balls, vertical ropes, shell fixing equipment and other components. Floating on the sea surface with multiple floating balls, when the oysters need to be harvested, the staff will drive the ship to the sea longline culture area, use tools to hook up the longlines in the water, and untie the upper ties one by one along the longlines. The hanging rope is used to lift it out of the water and onto the boat for harvesting. [0003] It can be seen that the existing oyster harvesting is completely dependent on manpower, which is inefficient, and the follow-up oyster collection and transshipment work also consumes a lot of manpower. Contents of the invention [0004] The technical pr...
