A pre-buried harvesting net system for shellfish farming

Abstract

The invention discloses an embedded harvesting net system for shellfish culture and relates to the technical field of aquaculture harvesting nets. The system comprises a traction machine and an embedding mechanism which is installed on the tail part of the traction machine and dragged by the traction machine; the embedding mechanism comprises a suspension frame, and a net roller mechanism is in rotary connection to the tail end of the suspension frame; the front end of the suspension frame is connected to a rotation shaft on the lower part of the rear end of the traction machine; a lifting mechanism is also connected between the middle part of the suspension frame and the traction machine; the net roller mechanism is composed of net rollers on the outmost layer, spoke connecting rods on the middle layer and a tube axis at the axis; the net rollers and the tube axis are firmly connected by the spoke connecting rods; a harvesting net axis roll is installed on the upper part of the suspension frame; and a harvesting net of the harvesting net axis roll bypasses from the net roller surface under the suspension frame and extends to the right rear part of the net rollers. According to the invention, energy consumption of shellfish harvesting can be reduced; the harvesting efficiency is high; shellfish growth environments only change a little; and the later sowing environment is very stable.

Description

technical field [0001] The invention relates to the technical field of aquaculture harvesting nets. Background technique [0002] At present, most of the harvesting of shellfish depends on manpower. When the pond culture drains clean water or the shallow beach ebbs, it is directly picked up by hand. There is also fishing with the help of simple raking tools, that is, when the tide on the beach is below 30cm, the workers hold clam rakes, iron sieves and net bags to plan the beach vigorously. The shellfish are concentrated in the collection net. Existing methods are time-consuming and labor-intensive, with low efficiency. [0003] There are also many mechanically automated shellfish harvesting machines at present. The main principle is to dig up mud and shellfish together, and then discharge the soil to screen the shellfish. This kind of harvesting method consumes a lot of energy, greatly damages the tidal flat ecosystem, and causes a sudden change in the living environment...

Problems solved by technology

This kind of harvesting method consumes a lot of energy, greatly damages the tidal flat ecosystem, and causes a sudden change in the living environment of tidal flat microorganisms.

It is not conducive to the stability of the environment for continued breeding in the later period
