The invention discloses a peanut excavation windrower which comprises a frame. A hanging frame connected with a drawing device is installed above the front end of the frame, an excavation device is installed under the front end of the frame, a lifting transportation device is installed on the frame at the back of the excavation device, a seedling laying device is installed on the frame at the back of the lifting transportation device, and a walking device is installed at the bottom at the back end of the frame. A transmission device used for transferring power to the lifting transportation device and the seedling laying device is installed on the frame. When the peanut excavation windrower is used, the hanging frame is utilized to connect the peanut excavation windrower onto the drawing device, peanut seedlings excavated by the excavation device are placed and gathered on the ground through the lifting transportation device and the seedling laying device sequentially in order, and collection of the peanut seedlings after drying is facilitated. The windrower adopts a frame structure, and is firm, reliable, even in stress, compact in structure, smooth in operation, low in cost, small in harvesting loss and high in working efficiency.
