Shearing type at-sea laver harvester

Abstract

The invention relates to a shear type offshore laver harvester. The harvester comprises a machine frame, an engine, a reduction gearbox, a belt-type transmission chain, a transmission shaft, a bevel gear transmission mechanism, a turning disc, a crank link transmission mechanism, a movable cutting tool and a fixed cutting tool, wherein the motor and the reduction gearbox are arranged on the machine frame, an output shaft of the engine is connected with an input shaft of the reduction gearbox, tan output shaft of the reduction gearbox is in transmission connection with the transmission shaft through the belt-type transmission chain, the transmission shaft is loaded on the machine frame, the transmission shaft is in transmission connection with the turning disc through the bevel gear transmission mechanism, the turning disc is in transmission connection with the movable cutting tool through the crank link transmission mechanism to allow the movable cutting tool to move left and right and shear relative to the fixed cutting tool, and fixed cutting tool is arranged on the machine frame below the movable cutting tool. The invention has the advantages of effectively controlling cut length of laver, avoiding crushing the laver like the prior laver harvester, achieving high cutting quality, along with simple structure, more mechanical advantages, stable transmission, and can meet requirements for high-efficient harvest of large areas of laver.

Description

technical field [0001] The invention relates to a harvesting machine, in particular to a shearing seaweed harvester. Background technique [0002] The traditional collection of sea laver is manually harvested. This harvesting method can guarantee a high yield, but its harvesting efficiency is very low, and it is only suitable for small-area harvesting. Along with the enlargement of seaweed culture area, the mode of artificial harvesting can't adapt to the demand of large area laver harvest. Therefore, some laver harvesting equipment came into being. They greatly improved the harvesting efficiency of laver and relieved the heavy physical labor of harvesters, but there was a big defect, which was that the yield of finished laver that met the product regulations after harvesting was relatively low. Low. [0003] Existing seaweed harvesting equipment generally consists of a blade and a cylinder welded to the blade. When harvesting, the cylinder rotates, and the blade forms a s...

Problems solved by technology

For example, the Chinese utility model patent No. 02216144.9 discloses such a laver harvester. During the laver harvesting process, this harvesting device not only rolls and cuts, but also rolls, and about 30% of the laver is smashed into Waste products may be thrown into the sea. In addition, the head and neck of the remaining laver are too short or uprooted due to rolling and rolling at the same time during harvesting, causing the laver to no longer grow or seriously reduce the yield.

[0004] The harvesting efficiency and yield of sea laver are important indicators for evaluating laver harvesting equipment. The existing sea laver harvesting equipment cannot meet the quality requirements of users for high harvesting efficiency and low waste rate.
