Abstract
The invention relates to construction, engineering machinery, mine, metallurgy and port storing and shipping equipment, in particular to a rolling harrow with separated harrow teeth. The rolling harrow with separated harrow teeth is used for a rolling-harrow loader and a harrow control material feeder. The rolling harrow comprises a rolling device and harrow teeth. Each of the harrow teeth comprises a tooth bit and a tooth bit fixing base, wherein the tooth bit fixing bases are arranged at intervals on the annular surface of the rolling device, and the tooth bits are movably connected with the tooth bit fixing bases. The rolling harrow has the advantages that the harrow teeth are divided into the tooth bits and the tooth bit fixing bases, so that the tooth bits can be changed rapidly and independently after being damaged, a rolling drum and the tooth bit fixing bases are not needed to be changed, and the tooth bit fixing bases and the rolling drum can be firmly manufactured; and the tooth bits are manufactured independently, so that the manufacture cost of the rolling harrow is reduced, only the tooth bit portions of the rolling harrow are made of special materials, and compared with the fact that the whole in made of special materials, the material cost is reduced greatly; and as for random accessories, only the tooth bits are arranged, so that waste of a large number of stockpiled rolling drums is reduced.
