Problems solved by technology

In this way, the physical strength of the workers is greatly consumed. When the seedling rope is very long, the long cable needs to be lifted very high, and the higher the long cable is lifted, the greater the lifting force, which is difficult for workers to bear only by physical strength.

Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0043] The main structure of the shellfish raft farming cable lifting and dragging device consists of a column 1, a base 2, a sliding seat 3, a winch 4, a reducer 5, a shaft 6, a groove wheel 7, an anti-jamming rope plate 8, a deviation plate 9, and a base 10. Composition of power source 11, such as Figure 1-2 shown.

[0044] The cross section of the column 1 is a square long rod connected vertically to the base 2. There are several through holes above the column 1 for fixing the slide seat 3; the hoist 4 is fixed above the column. The hoist 4 can be driven by hand or power, and the steel wire of the hoist 4 is connected to the slide seat. 3. It can drive the sliding seat to slide up and down along the column 1; the reducer 5 is installed under the sliding seat 3, and the reducer 5 is connected to the grooved surface wheel 7 through the shaft...

Abstract

The invention relates to a mooring rope lifting and dragging device for raft type shellfish culture. The device comprises a stand column arranged on a side of a pontoon, a sliding seat sliding along the stand column and a winch fixed to the stand column; a rotatable groove face wheel is fixed to the sliding seat and protrudes out of the side, and a wheel body of the groove face wheel is parallel to the side; the groove face wheel is provided with a power source driving the groove face wheel to rotate; and a rope of the winch is fixedly connected with the sliding seat located below the rope. By using the device, traditional rope lifting and dragging work of fishermen during shellfish harvesting is replaced, main harvesting work is completed at a position above a deck, and physical output of workers is greatly reduced. Meanwhile, continuous operation can be achieved through mechanical work, the work time is greatly saved, and the work efficiency is improved. Besides, the device is used for seedling distribution and harvesting work of a long-mooring-rope shellfish culture raft frame, and the device can be applied to the working condition of single-mooring-rope lifting and dragging on the water surface.

Description

technical field [0001] The invention relates to a shellfish raft culture cable hoisting and dragging device, which belongs to the technical field of shellfish culture. Background technique [0002] In the prior art, most of the offshore shellfish culture rafts are connected by long cables, buoys and the like. Shellfish seedlings are grown on ropes tied to long cables. In the traditional operation, in the stage of planting and harvesting, small ships are usually manually driven to work close to the long cable. During the operation, the worker lifts the long cable from the sea and fixes it on the piercing, cuts off the seedling rope on the side of the ship and drags it into the cabin. Put the cable back into the sea, and the worker drives the ship forward for a certain distance, then stops and repeats the operation. In this way, the physical strength of the workman is very great. When the seedling rope is very long, the long cable needs to be lifted very high, and the higher...
