Quantitative feed feeding device for pig breeding

The invention belongs to the technical field of live pig breeding, and particularly relates to a quantitative feed putting device for live pig breeding, which comprises a main body, a feeding basin is arranged at the lower end of the main body, and an electric telescopic rod for driving internal elements to move up and down is arranged in the main body. An electric telescopic rod is driven to rotate, a first scraping plate is ejected out downwards to scrape off feed on the inner wall of the main body, the first scraping plate can be driven to ascend automatically through elasticity of an elastic column when the electric telescopic rod is retracted, and secondary cleaning is conducted through a second scraping plate; the feed can be effectively prevented from adhering to the inner wall to form dirt and deteriorate, and subsequent normal use of the feed is guaranteed; an arc-shaped pad can be compressed towards the inner side by extruding a limiting plate towards the interior of a sliding groove, an opening of
