Electric motor with hollow ventilating main shaft and feeder with the same

Abstract

The invention belongs to the technical field of aquaculture machineries, and in particular relates to a motor with a hollow ventilating main shaft and a feeding machine with the same. The motor is characterized in that the main shaft is of a hollow structure, the lower end of a shell is connected with a flange, a bearing is arranged between the shell and the main shaft, a stator is fixed on the shell, the shell is connected with a base by virtue of the flange, a rotor is fixed on the main shaft, thereby forming an inner rotor motor; or the stator is fixed on the main shaft, the rotor is fixed on the shell, the main shaft is fixed on the base, thereby forming an outer rotor motor. The feeding machine with the motor is characterized in that a feed delivery pipe is arranged between a feeding mechanism and a throwing mechanism; the upper part of a 360-degree throwing tray is closed, the lower part of the throwing tray is provided with a feed port, and the throwing tray is arranged on the main shaft; the inner hole of the main shaft is dead against the feed port, a hollow shaft enters into the feed port at the lower part of the throwing tray; and the throwing mechanism is installed in fish ponds, the feeding mechanism is installed on the shore, and the negative pressure generated by rotating the throwing tray absorbs the feed to the throwing tray from the feeding mechanism so as to throw out the feed.

Description

technical field [0001] The invention belongs to the technical field of aquaculture machinery, in particular to an electric motor with a hollow ventilated main shaft and a feeding machine with the electric motor which feeds from the through hole of the main shaft of the electric motor. Background technique [0002] Feeding machine is an indispensable equipment for aquaculture. Usually the feeding machine is installed on the bank of the fishing pond, and the feed can only be thrown from one side. There is also a feeding machine with double-sided feeding, such as patent number: 200620165358.0, but this patent consists of two throwing motors, and the structure is complicated. It cannot feed in a large area, and the existing feeding machines are not suitable for feeding benthic aquatic products such as prawns, because the range of activities of prawns is small, and the prawns swim to a small range to eat and feed, which will cause damage due to excessive density , so most of the...

There is also a feeding machine with double-sided feeding, such as patent number: 200620165358.0, but this patent consists of two throwing motors, and the structure is complicated. It cannot feed in a large area, and the existing feeding machines are not suitable for feeding benthic aquatic products such as prawns, because the range of activities of prawns is small, and the prawns swim to a small range to eat and feed, which will cause damage due to excessive density , so most of the existing shrimp farming adopts manual feeding
