abstract
The utility model discloses a harvesting digging device and a multifunctional peanut harvester with the digging device. The excavating device comprises a rotatable auger and a cage-type tool rest rotating around the auger, wherein a screen is arranged below the auger; the cage-type tool rest consists of two side end covers and cage bars connected between two end covers; the outer wall of each cage bar is provided with an excavating knife with an outward cutter head arranged along the axial direction; and the end covers of the cage-type tool rest are connected with a transmission device. The harvesting digging device of the utility model is provided with a cage-type tool rest on the periphery of the auger, and each cage bar of the cage-type tool rest is provided with digging knives arranged along the axial direction. When the cage tool rest rotates, the digging knives arranged side by side on the cage bars can dig peanut roots out of the ground. Due to the small cutting edge and bit area of the digging knife, the digging resistance is small, the working efficiency is high, and the fruit breakage rate is low.
