Abstract

The invention relates to engineering machinery, in particular to a screening bucket of an excavator. The bucket can be automatically installed through cooperative work of oil cylinders, primary screening can be carried out through a screening bucket assembly, secondary screening can be carried out through the excavator bucket, and tertiary screening can be carried out through an adjustable screening plate assembly. When the bucket is installed, a first arc hook hooks a pin shaft on the bucket, the second arc hook hooks the pin shaft on the bucket, and installation is automatically completed. During use, screening holes in the screening bucket play a role in primary screening, a motor drives a crankshaft to move, and the radial movement of a crankshaft connecting rod is converted into the reciprocating movement of the screening bucket around a sixth rotating shaft in a bucket body; the bucket body plays a role in secondary screening, and water is sprayed outwards from a spray head to achieve the effects of cleaning and dust removal; and the motor drives a one-way clutch and a sleeve to only rotate in one direction, so that all connecting rods of the screening plate assembly can be straightened, screening plates are fixed to all the connecting rods, and every two adjacent screening plates play a role in tertiary screening.

Description

technical field [0001] The invention relates to a construction machine, more specifically to an excavator screening bucket. Background technique [0002] The excavator screening bucket is a common construction machine, which is widely used in crushing and screening soil, bricks, stones, etc., but the existing screening bucket has a single function and cannot be screened multiple times. Contents of the invention [0003] The purpose of the present invention is to provide a screening bucket of an excavator, the bucket can be installed without manual assistance through the cooperative work of the bucket cylinder and the bucket loading cylinder, and the first screening can be performed through the screening bucket assembly , the second screening can be performed through the fixed connecting rod and rib at the rear end of the excavator bucket, and the third screening can be performed through the adjustable screening plate assembly. [0004] The purpose of the present invention...
