A mobile automatic feeding device for bullfrog breeding

Abstract

The invention discloses a movable and automatic throwing and feeding device used for culture of bullfrogs. The device comprises a feeding device, a movable device and a bearing device. The interior of a material storage barrel is provided with a rotary shaft and stirring blades. The upper left part of the material storage barrel is provided with a feeding port. The lower right part of the material storage barrel is provided with a control box, in which a power supply chamber, a first motor, a first coupling, a corner reducer, a second motor, a second coupling and a speed reducer are arranged. The corner reducer is connected with the rotary shaft. The movable device is connected between the feeding device and the bearing device and comprises a driving shaft, a driving wheel, a transmission shaft, a transmission wheel and a bottom board. The driving shaft is connected with the speed reducer. The bottom board is connected with a discharge port in a penetrating manner. The bearing device comprises a bearing board, a guide strip, a material throwing groove and a fixing mechanism. The movable and automatic throwing and feeding device used for culture of bullfrogs helps increase an interest in bullfrog preying.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a mobile automatic feeding device for bullfrog breeding. Background technique [0002] The bullfrog, scientific name Rana catesbeiana, is a solitary aquatic frog. It is larger than other frogs and has a voice like a cow, hence the name bullfrog. It is the largest frog in North America. Belonging to the chordate door, vertebrate subphylum, amphibian class, anura order, frog family, frog genus. Bullfrogs are native to several states in the eastern part of the United States, and then introduced into western states and other countries. The bullfrog has a green or brown body, white to light yellow abdomen, and black stripes on the limbs. The body is about 20 cm long, and the hind limbs are as long as 25 cm. Adults weigh more than 0.5 kg. Usually live in still water or near it, reproduce in spring, and in the water where eggs are laid, tadpoles are greenish brown wi...

AI Technical Summary

Problems solved by technology

Traditionally, the feeding of bullfrogs has relied on artificial baiting, which is inefficient and requires people to throw food for a long time, resulting in a great waste of manpower. Moreover, bullfrogs will avoid people when they come, so the breeding efficiency is also poor.
