Problems solved by technology
[0003] Existing excavators mainly use open buckets. Generally, the capacity of a single bucket is small, and it is easy to cause the soil to scatter during the excavation process. Moreover, when the soil is hard, it is difficult to penetrate deep into the soil due to the high resistance during excavation. Large power required, low work efficiency

The invention relates to a drilling bit type cylindrical digging bucket of a digging machine with four fan-shaped shoveling plates, which comprises a cylindrical bucket body, wherein the cylindrical bucket body is fixedly connected with the inner ring of a rolling bearing A through a bucket neck, the outer ring of the rolling bearing A is fixedly connected with a body support frame arranged on the front arm of the digging machine, a crossed support frame is arranged at the bottom of the cylindrical bucket body, the lower part of the cylindrical bucket body is provided with the four fan-shapedshoveling plates, one right-angle edge of the fan-shaped shoveling plates is fixedly arranged on a gear shaft B arranged on the crossed support frame, one end of the wall surface of the gear shaft B near the cylindrical bucket body is sheathed with a bevel gear B, a bevel gear A which is sheathed on one end of the gear shaft A is engaged on the bevel gear B, the top end of the gear shaft A is provided with a small circular gear, a large circular gear engaged with the small circular gear is sheathed on a fixed rod which is sheathed in the center of the top of the cylindrical bucket body, two two-way hydraulic cylinders are fixed on the cylindrical bucket body, one end of a piston rod of the two-way hydraulic cylinders is fixed on the wall surface of the bucket body through a rolling bearing C, and the other end of the piston rod of the two-way hydraulic cylinders is fixed on the disc surface of the large circular gear through the rolling bearing B. The invention has the advantages of large digging amount, small required motive power and high digging efficiency.
Description
technical field [0001] The invention relates to an excavator bucket, in particular to a four-sector shovel plate drill type cylindrical bucket of the excavator. Background technique [0002] Excavator is an important earthwork machinery, widely used in earthwork construction and mining operations such as house construction, road engineering, water conservancy construction, farmland development, port construction, national defense fortifications, etc. [0003] Existing excavators mainly use open buckets. Generally, the capacity of a single bucket is small, and it is easy to cause the soil to scatter during the excavation process. Moreover, when the soil is hard, it is difficult to penetrate deep into the soil due to the high resistance during excavation. Need power big, work efficiency is low. Contents of the invention [0004] The object of the present invention is to overcome the above-mentioned defects existing in the prior art, and provide a kind of excavator four-sect...
