A shellfish farming and harvesting device based on a pre-buried harvesting net

Abstract

The invention discloses a shellfish culture and harvesting device based on an embedded harvesting net and relates to the technical field of aquaculture harvesting nets. The device comprises a traction machine, a harvesting cabin assembly installed on the traction machine, and a net hauling separation mechanism installed at the tail part of the traction machine, wherein the harvesting cabin assembly comprises transmission channels installed on the left and right sides of the traction machine and a harvesting cabin installed on the head part of the traction machine; the net hauling separation mechanism is located between rear end parts of the two transmission channels; the net hauling separation mechanism comprises a supporting frame which is vertically installed at the tail part of the traction machine; a horizontally disposed rotation shaft of the harvesting net is installed on the top end of the supporting frame; a movable supporting frame is connected to the traction machine by a rotation shaft on the front part of the supporting frame; the upper end of the movable supporting frame is connected to a driving wheel by a rotation shaft; an A hydraulic lifting rod is in rotational connection between the upper part of the movable supporting frame and the traction machine; and a triangular vibration plate which is disposed in an inclined manner is disposed on the rear part of the supporting frame. According to the invention, energy consumption of shellfish harvesting could be reduced; the harvesting efficiency is high; and labor strength of manual harvesting could be reduced.

Description

technical field [0001] The invention relates to the technical field of aquaculture harvesting equipment. 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 enviro...
