A fully automatic uniform bait casting boat for river crab breeding

Abstract

The invention provides a full-automatic uniform feeding boat for river crab culture. The full-automatic uniform feeding boat for river crab culture comprises a boat body, an automatic feeding device and an electrical control device. The automatic feeding device is arranged on the stern of the boat body and comprises a hopper, pressure sensors, a plurality of funnels, bait valves, a valve motor and a plurality of material guide pipes. The funnels are arranged at the bottom of the hopper side by side, the two sides of each funnel are both provided with the pressure sensors, the bottom of each funnel is provided with one bait valve communicated with the corresponding material guide pipe, the opening degree of each bait valve is controlled by the valve motor, and the material guide pipes obliquely extend to the outside of the stern. The electrical control device comprises an embedded ARM processor, a GPS navigation module, an attitude module, a GPRS wireless remote monitoring module and an ultrasonic distance measuring sensor, wherein the GPS navigation module, the attitude module, the GPRS wireless remote monitoring module and the ultrasonic distance measuring sensor are connected with the embedded ARM processor respectively, and the embedded ARM processor is further connected with the pressure sensors and the valve motor. According to the full-automatic uniform feeding boat for river crab culture, feedback control over the feeding amount is achieved, and track control is flexible.

Description

technical field [0001] The invention relates to an automatic bait-casting boat, in particular to a full-automatic uniform bait-casting boat for river crab breeding. Background technique [0002] With the development of agricultural mechanization and automation technology and the improvement of people's living standards, the market demand for river crab products continues to increase, and the breeding technology and management of river crabs are constantly updated. However, due to the strong geographical restrictions of river crab farming, river crabs cannot be moved in large areas. , can only look for food in the area near itself; at the same time, it is the nature of river crabs to compete for food and aggressiveness, and they will kill each other when the density is high and the bait is scarce; Fleeing due to low dissolved oxygen. Yet river crab culture adopts three kinds of ways at present: The one, throws bait and feeds by artificial punting. This mode has low working ...

AI Technical Summary

Problems solved by technology

This method has low work efficiency and high labor intensity, and it is difficult to increase the output of river crab culture; the second is to rely on bait feeding machines to feed

Although this method uses manual operation to feed regularly and quantitatively to save labor, the bait feeder is a fixed-point feeder that can only be fixed at a certain place to feed. This bait feeder is only suitable for small areas such as circles. crab ponds, and there is also uneven distribution of bait; the third is to feed through the ship-borne bait feeder

It is suitable for some small-scale farms. When feeding, people row a small boat along the edge of the pond, and then throw the bait to the pond through the bait feeder installed on the boat, but this method is troublesome and laborious, and the feeding point is easy. Changes with the rowing operation, affecting the feeding effect

The automatic baiting boat with a relatively high degree of automation is also uncontrolled due to the uncontrolled baiting device. Once there is relatively large interference from the outside world, it is difficult for the ship to sail at a constant speed. Decelerate to a certain speed and then turn around or stop, etc., which makes it impossible for the ship to maintain a constant speed

Moreover, the distribution of the bait thrown by the traditional bait feeder looks like a fan, and the distribution of the bait thrown by the bait feeder carried by the ship is a slanted fan one by one. When the boat is driving, it is easy to cause blanks in the bait area distributed in the pond. or overlapping

[0003] In summary, the existing baiting methods are difficult to achieve uniform baiting

[0004] In the special breeding environment of river crab farming, there is a strong dependence on the uniformity of bait feeding. Uneven distribution of bait can easily lead to excessive or insufficient bait feeding. Putting too much bait will not only increase the cost, but also lead to water pollution
