AI Technical Summary

Technical Problem

During kelp harvesting, the propeller is easily entangled in seaweed, the blades can easily cut the kelp, and the speed of the propeller-driven hull is not easily matched with the harvesting speed, resulting in significant power loss.

Method used

Design a kelp stem clamping device to pull the harvesting vessel forward by clamping the kelp stems. The device includes a frame, an axial adjustment mechanism and a clamping mechanism. The kelp stems are clamped by clamping sliders and clamping plates. The motor drives the shaft to rotate, which in turn drives the clamping disc to rotate synchronously, so as to achieve stable clamping of the kelp stems.

Benefits of technology

It changed the way the harvester moves forward, avoiding the problems of propeller entanglement and cutting of kelp, improving power transmission efficiency, adapting to kelp stems of different diameters, and the clamping slider and thin sheet can be disassembled and replaced to ensure clamping force.

Abstract

This utility model discloses a kelp stem clamping device, aiming to provide a simple device for kelp harvesting vessels that can stably provide power without damaging the kelp, thereby improving economic efficiency. The device consists of a frame, an axial adjustment mechanism, and a clamping mechanism. The frame includes a left frame and a right frame, respectively fixed to the hull deck. The left frame is equipped with a motor, which drives the shaft to rotate via a coupling. The left and right frames are supported by bearings. The axial adjustment mechanism includes adjustment shims and a variable-pitch ring. The variable-pitch ring is a circular ring with a variable axial length. The distance between the left and right frames is controlled by adjusting the number of adjustment shims to accommodate the clamping requirements of kelp stems of different diameters. The clamping mechanism includes a clamping disc A, an arc-shaped strip, a clamping slider, a clamping disc B, and clamping plates. Several arc-shaped strips are evenly welded onto clamping disc A, and the clamping slider has corresponding openings at its bottom that fit onto these strips. Several clamping plates are correspondingly welded onto clamping disc B. The two discs rotate with the shaft via a key. The clamping slider, through the axial movement of the pitch-adjusting disc, together with the clamping plates, clamps the kelp stems. This device flexibly adjusts the clamping distance through an axial pitch adjustment mechanism, and the clamping mechanism is designed to enhance clamping force and stability, improving kelp harvesting efficiency and quality. It has advantages such as simple structure, convenient operation, and reliable clamping, and is suitable for mechanized kelp harvesting operations.
