The invention relates to a rotary tiller blade assembly which comprises a blade tube and blades, wherein blade holders are fixedly arranged on the blade tube, each blade holder is provided with three blade seats which are radically arranged, grooves are formed on the backs of the blade seats, and the end parts of the blades are inserted into the grooves and are fixedly connected with the blade seats through bolts. The rotary tiller blade assembly further comprises anti-twining plates which are welded at the side edges of the blade seats. The blades of the rotary tiller blade assembly provided by the invention are mounted through the blade holders, so that the length of the blades is shortened and the weight of the rotary tiller blade assembly is reduced by 25%, thereby saving the material. In addition, the anti-twining plates are fixedly connected with the blade holders by welding, so that the rotary tiller blade assembly is simple to mount and low in cost.
Description
technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a rotary tiller. Background technique [0002] At present, the main farmland tillage machines are rotary tillage machines, which loosen the land by cutting and breaking soil clods with rotary tillers. The area is widely used. The rotary tiller is an important part of the rotary tiller. At present, the common rotary tiller mainly includes the knife barrel 1', the knife plate 2, the blade 3' and the anti-wrapping plate, such as figure 1 As shown, the knife plate 2 is fixedly installed on the knife barrel 1', and the knife plate 2 is provided with a plurality of bolt holes 4, and the root of each blade 3' needs to be fixedly connected to the knife plate by two bolts. Therefore, the Longer length and heavier weight make the whole rotary cultivator very bulky. In addition, in the existing rotary tiller, the anti-wrapping plate 5 is fixedly connected to the connecting...
