The invention provides a hilling cover structure of a framing machine, characterized by disposing a support frame at the front edge of the framing machine main body. A positioning element is disposed on the support frame. A gear box is disposed at one side of the main body. Two L-shaped connection bases are arranged at two sides of the support frame, respectively. A cover is pivoted at the outer side surface of the two connection bases through a pivot element. A positioning linkage is disposed on the cover to threadingly position the positioning element on the support frame. A side cover is pivoted at the side surface of the cover through a pivot element. A blade is covered within the cover. Therefore, the cover can be extended outwardly by the connection base. When the cover is lifted outwardly, it can avoid being contacted with the gear box so as to be lifted with a relatively large angle. The earth shoveled by the blade can be smoothly discharged outwardly.本發明係在提供一種農耕機之培土覆蓋結構,主要係於農耕機之機體前方設有支撐架,該支撐架上設有定位構件,機體之一側設有傳動箱,於支撐架之二側分別設有一呈L形之連接座,該二連接座之外側面係分別藉由樞接元件樞設有罩蓋,於罩蓋上設有定位連桿供支撐架上之定位構件穿設定位,於罩蓋之側面藉由樞接構件樞設有一側蓋板,罩蓋內罩設有刀具;如此,藉由連接座之設置可將罩蓋向外延伸,使罩蓋在向外翻掀時,可避開機體一側之傳動箱,不會受傳動箱阻擋而可向外翻掀更大之角度,以供被刀具剷起的土可順利的向外排出。
