Intelligent stepless speed controller of weighing feeder

Abstract

The invention discloses an intelligent stepless speed controller of a weighing feeder. The intelligent stepless speed controller is formed by connecting a safety circuit (1), an input device circuit (2), an emergency switch (3), a reset switch (4), a latching circuit (5), a relay J1 drive protection circuit (6), a material throwing indicating drive output circuit (7), an output protection circuit (8), a speed control drive output circuit (9), a wiring terminal (10), a weighing detection circuit (11), a zero-cross detection circuit (12), a power supply indicating circuit (13), a rectifying and voltage stabilizing circuit (14), a transformer (15) T1, a single chip microcomputer (18) U2 and a relay J1 in an electric loop mode. According to the intelligent stepless speed controller, the single chip microcomputer with an AD interface serves as a core control element, and therefore input arrangement is simple; a timer is replaced by the feeding amount to control the duration of available machine time, accurate feeding is achieved, the feed utilization ratio is improved, and the intelligent stepless speed controller is good in control performance and easy to operate.

Description

technical field [0001] The invention relates to a controller, in particular to an intelligent stepless speed-regulating controller of a feeder by weight. Background technique [0002] Along with the mechanization development of aquaculture industry, feeder is widely used, and the work of feeder is realized by controller, does not also have feeder by weight and speed-regulating controller by weight so far. The currently used feeding machine is to control the length of each start-up time, relying on manual experience, through mechanical adjustment to control the size of the feeding amount, can only roughly control the feeding amount each time, and cannot accurately control each feeding amount This control method cannot grasp the amount of feeding, and cannot adapt to the scientific breeding needs of farmers. Contents of the invention [0003] The purpose of the present invention is to provide an intelligent stepless speed regulation controller for weight feeding machine, wh...
