Laver harvester for boat

Abstract

The invention relates to a marine laver harvester, which mainly comprises a combined scissors cutter, a transmission device, a driving device, a protective device and a frame. The invention is characterized in that, the combined scissors cutter mainly comprises a movable blade orientation wheel 3, a movable blade 4 and a fixed blade 5; the transmission device mainly comprises a drive rod 7, a positioning pulley 8 and a location frame 9; the driving device mainly comprises a clutch 29, an eccentric driving wheel 32, a drive connecting rod 31 and a gear box 30. The marine laver harvester has the advantages that, (1) by adopting the technical proposal, the drawbacks of marine rotary hob type laver harvester are overcome; the length of the remained laver head can be adjusted freely during cutting; the harvest of ductile laver is facilitated; lateral once unified rapid harvest of web curtain culture is resolved; the work efficiency is improved to eight to ten times of the artificial work efficiency; (2) laver decay caused by delay harvest resulted from weather changes is avoided, and yield increase and income increase are realized; (3) the harvester has compact size; diesel engine is adopted to provide momentum, and the invention is equipped with a clutch; the structure is rational, and the operation is simple and convenient.

Description

Technical field [0001] The invention relates to the technical field of laver harvesting and cutting, in particular to a marine laver harvester used for net curtain culture of laver. Background technique [0002] At present, the seaweed harvester commonly used by fishermen is a rotary hob harvester with Chinese patent number 01230511.1. Its structure is characterized in that it has a drum with cutting knives installed on the drum. There are three cutting knives, which are pressed along the circumference of the drum. Installed in 120 compartments, the length of the cutter is equivalent to the length of the drum. This type of rotary hob harvester has the following shortcomings: (1) There are often too long remaining vegetable heads during harvesting, which may easily cause the rot of laver. (2) The tough seaweed cannot be harvested, which virtually causes a reduction in production. (3) It is impossible to achieve a unified harvesting horizontally for net-curtain farming. [0003] In...
