Device for feeding shrimps and crabs

Abstract

The invention provides a device for feeding shrimps and crabs. Both sides of a horizontal axle have a roller respectively; a machine frame is fixed above the axle, and the center of the machine frame is fixedly provided with a generator; the generator is connected with a transmission box; the axle is connected with a main shaft of the transmission box, and an auxiliary shaft of the transmission box is sequentially connected with a rotor of the generator and an impeller middle shaft of a centrifugal fan by couplings; a saddle-shaped hopper is arranged above the generator, two lower ends of the saddle of the hopper are connected with each other by a spiral feeder, and the bottom part of the output end of the spiral feeder is provided with a discharge hole which is communicated with an opening of an air discharge tube by a downwards inclined material-conveying tube; and the other end of the hopper is provided with a motor. The device has multiple functions; the device can realize movable feeding, plowing and the like; and the device has high flexibility and adjustable traveling speed and feeding quantity.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a device for feeding shrimps and crabs. Background technique [0002] The traditional aquaculture feeding method is to set up a bait table in the middle of the aquaculture pond 3 to 4 meters away from the pond ridge. Generally, two ponds are set up per mu, and fixed-point feeding is carried out on the bait table. This feeding method is more suitable for fish farming. . [0003] In recent years, the shrimp and crab aquaculture industry has developed rapidly, the aquaculture area has expanded year by year, and the proportion in the aquaculture industry has increased year by year. The feeding habits of shrimp and crabs are quite different from those of fish. Taking river crabs as an example, river crabs are very gluttonous, eat a lot, and have a strong digestive ability. It eats both meat and vegetables, and likes to eat animal foods such as fish, shrimp, snails, worms, earthworms, inse...

AI Technical Summary

Problems solved by technology

[0004] Because shrimp and crabs have obvious cannibalism and strong land occupation habits, the traditional fixed-point feeding machine feeding method is obviously not suitable for shrimp and crab farming. Therefore, the current shrimp and crab farming mostly adopts the method of walking around the pond and manually spreading the feed. Feeding, this kind of feeding method has low efficiency, high labor intensity, uneven bait feeding, serious waste, high breeding cost, and easy pollution of water quality, which seriously restricts the development of shrimp and crab aquaculture.
