technical field

The invention belongs to the technical field of fishery engineering machinery, and in particular relates to a device system for trawl fishing in aquaculture ponds.

Background technique

Pond farming netting is a method of hauling nets in ponds to catch market-sized product. A fishing net can be a simple trawl net or a specially made net for the purpose, usually using polyethylene or nylon line and equipped with floats, drop hammers and sometimes a mesh pocket. The size of the trawl used depends on the size and depth of the pond used for the operation. The general height is 2.5-9 meters, and the length is equivalent to 1.6 times the width of the pond. The selected mesh should be determined according to the specifications of the products sold, and the applicable mesh size is 1-5 cm.

The bottom of the trawl remains dragged over the bottom of the pond. If this is not done, many fish and shrimp will slip through the net. It is best to trawl along the long sides of the pond, generally using rectangular ponds with a maximum width of 50 m, so that both ends of the net can be trawled along the banks.

Trawling in the prior art is manual, and the more people who carry out the trawl operation, the higher the efficiency. 3 to 5 people can pull the net in a pond with a width of 30 meters, and 7 to 10 people can handle a pond with a width of 50 meters. . It takes about 2-3 hours for 3 to 4 people to catch the big and keep the small in a 0.2-hectare breeding pond with a single net.

There are also pond cultures that need 8-10 people when raising the nets, and it takes a lot of time to raise the nets for 0.5-1 hour. high.

Detailed ways

The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

A simple trawling system for aquaculture ponds,

On both sides of the length direction of the pond G, a ground pile 1 is arranged at the front and rear ends respectively, and a steel wire guide rope 2 is tightened between the ground piles 1 at the front and rear ends of each side, and the lateral ends of the mesh bag 3 are respectively pulled to two The side wire guide rope 2 is connected to the collar that penetrates the wire guide rope 2. The net bag 3 rope is terminated with a snap button, which can be easily disassembled. The collar is pulled by the trawl wire rope 4, and the two trawl wire rope 4 Merge into the left and right trawl winches 53,54 in the traction device 5 after being nested in the ground pile 1 of the front end respectively, and the left and right trawl winches 53,54 are powered by the tractor 6.

When tractor 6 starts, left and right trawl winches 53,54 rotate, and the lateral two ends of mesh bag 3 are pulled forward slowly by trawl wire rope 4 respectively and tighten up. Only one tractor 6 is needed to realize the trawling operation of the mesh bag 3 .

The ground pile 1 is a socket structure between a female pile 11 and a sub-pile 10. The female pile is fixed on the ground surface and has a movable cover plate, and the sub-pile 10 can be inserted and pulled out for disassembly. The female pile 11 is nailed to the ground surface, slightly exposed to the ground surface. When not working, cover it with a cover plate to prevent rainwater from entering. The sub-pile 10 is detachable. Take it out and put it on the trailer together with the wire guide rope.
