Scraper mechanism for feed shifting mechanism

The utility model discloses a scraper blade mechanism for a feed shifting mechanism, which comprises a fixed seat, a second rotating shaft and a scraper blade, the second rotating shaft is rotatably connected onto the fixed seat, the scraper blade is fixedly connected onto the second rotating shaft, the scraper blade is used for scraping off residual feed on a conveying mechanism, the second rotating shaft is fixedly connected with a connecting arm, and the connecting arm is provided with a balancing weight. Under the gravity action of the balancing weight, the balancing weight is kept in a vertical state, and the second rotating shaft rotates on the fixing seat, so that the scraping plate is attached to the tail end of the conveying mechanism, the scraping plate acts on the conveying mechanism, at the moment, the scraping plate scrapes off residual feed on the conveying mechanism, and waste of the feed is reduced by collecting the scraped-off feed; the balancing weight is adopted to drive the second rotating
