Autonomous navigation raising and bait feeding device for river crabs and uniform bait feeding method

Abstract

The invention discloses an autonomous navigation raising and bait feeding device for river crabs and a uniform bait feeding method. A pneumatic air-blast bait feeding device and an electrical control device are arranged on a paddle wheel power bait feeding ship body, wherein the pneumatic air-blast bait feeding device mainly comprises an automatic bait feeding machine, a fan and a gas distributor; the electrical control device mainly comprises an ARM9 control panel as well as an upper computer communication device, a GPS (Global Positioning System) / INS (Inertial Navigation System) combined navigation device and a paddle wheel driver which are connected with the ARM9 control panel. The uniform bait feeding method mainly comprises the following steps: firstly, establishing a coordinate system of a rectangular working area of a crab pond; secondly, determining a circle number of internal spin uniform bait feeding; thirdly, calculating internal spin uniform bait feeding target points to generate a target bait feeding path; fourthly, calculating the flows of all channels of a bait feeder according to the target bait feeding density and the current ship speed, and performing the internal spin uniform bait feeding. According to the autonomous navigation raising and bait feeding device and the uniform bait feeding method disclosed by the invention, accurate control over bait feeding operation can be realized, raising benefits can be remarkably improved, and the development of a river crab raising industry is promoted.

Description

technical field [0001] The invention relates to the field of automatic feeding for aquaculture, in particular to automatic feeding for river crab farming. Background technique [0002] River crab is an important freshwater crab in my country. Its meat is delicious and nutritious, and it has won the favor of consumers. In recent years, with the continuous increase of market demand, the scale of river crab farming has also been expanding, bringing good economic benefits to fishermen. In the process of cultivating river crabs, feeding and casting bait is a very important task. However, because river crabs crawl slowly and have limited range of activities, they can only forage in the area near themselves. Uneven feeding of bait will lead to too much or too little bait in some parts. When there is too much bait, it will not only cause waste of bait, but also cause excessive concentration of river crabs, resulting in excessive consumption of local dissolved oxygen, which will cau...

Problems solved by technology

However, this method needs to lay a circular slideway on the edge of the pond, which has a high cost and cannot easily transplant the equipment to other ponds. At the same time, when the pond area is large, the bait feeder cannot cover the central area of ​​the pond, resulting in waste The breeding space of the pond; the patent "remote control automatic bait casting boat" with application number 02229989.0 can be operated remotely by remote control, but its route is completely dependent on manual experience, and its loading capacity is small, so it cannot complete large-scale pond feeding.
