Automatic unfastening device for kelp harvesting

Abstract

The invention relates to an automatic unfastening device for kelp harvesting. The device comprises an upper lifting rope, a lower lifting rope and a rope fastener, wherein the width of a narrow groove in the lower part of the rope fastener is smaller than the external diameter of a knot at the head of the lower lifting rope. The device further comprises a pressure block, a driver and a screw rod, wherein the driver is connected with the screw rod, and the pressure block is driven by the screw rod to transversely move; the knot is attached to a platform, a micro switch is arranged on the platform, and is used for feeding back an electric signal to a control unit to trigger the driver to work after receiving a touch signal of the knot, and the screw rod is driven by the driver to transversely move until the knot is tightly pressed by the pressure block; a torsional spring is arranged on the platform, the resistance of the torsional spring is overcome by the rotating force of the screw rod, the pressure block and the platform are driven by a guide pin shaft to rotate to one side of a rope groove, the knot enters the rope groove, and when the pressure block rotates approximately to 90 degrees, the knot is transversely moved and separated from the narrow groove in the lower part of the rope fastener by the lower lifting rope under the action of tensioning force, and the lower lifting rope is separated from the rope fastener.

Description

technical field [0001] The invention relates to an auxiliary device for harvesting kelp, in particular to an automatic unlocking device for harvesting kelp, which belongs to the technical field of fishery instruments. Background technique [0002] As an important economic value of seaweed, kelp has extremely high edible value and industrial value. Due to the difference between the kelp cultivation method and the traditional algae cultivation method, although the kelp harvesting machine has been studied by many scientific research institutions, it often has defects in economic applicability and has not been widely promoted. At present, there is no mature plan for the kelp harvester, and most of them are in the design and development stage of the principle prototype. The harvesting principles are mainly divided into two categories. One is to set up a pulling rod and a dragging device on the hull, drag the kelp seedling rope to the hull, and then manually untie the rope, ther...

Problems solved by technology

[0003] The technical problem to be solved in the present invention is: based on the traditional kelp raising mode, when the kelp is manually harvested, it is necessary to manually cut off the hoisting rope that is connected with the kelp growing rope and the floating rope and drag it to the deck of the transport ship. And manual stacking, the labor intensity is huge, very hard
