Vibrating type excavating bucket applicable to excavator

Abstract

The invention discloses a vibrating type excavating bucket applicable to an excavator. The vibrating type excavating bucket applicable to the excavator comprises an arc-shape plate and side plates arranged on two sides of the arc-shape plate. The excavating bucket further comprises baffles. A vibration chamber is formed by the baffles, the arc-shape plate and the side plates jointly. A vibrating device is arranged in the vibration chamber. The vibrating device comprises a driving assembly. The driving assembly is fixed to a concave portion of the arc-shape plate through a center support plate.The driving assembly is connected with a rotary shaft. Eccentric gears are arranged on the rotary shaft. The driving assembly is arranged between the two eccentric gears. Both of the two ends of therotary shaft are connected with end support plates correspondingly. The end support plates are fixed to side plates. The vibration chamber is connected with a cable assembly. The vibrating type excavating bucket applicable to the excavator is vibrational when excavation is conducted, and a rapid soil-loosening effect is acquired; when encountering obstacles such as small gravels, the excavating bucket can smash the obstacles through vibration or remove the obstacles by utilizing the vibrating force; the problem brought about by force bearing of a traditional excavator that too large stress concentration might lead to early fatigue rupture of components is solved; and then working efficiency of the excavator and the service life of the excavating bucket are improved.

Description

technical field [0001] The invention relates to the technical field of excavators, in particular to a vibrating bucket suitable for excavators. Background technique [0002] Excavator is a kind of shovel loading and transportation machinery, which plays an important role in the construction of national economy such as transportation, aerospace, water conservancy engineering, and mining. Among them, the bucket is used as the execution part to complete the entire work order of the excavator. The production efficiency, service life and maneuverability of the excavator depend on its performance. [0003] The bucket part is composed of lug plate, hinge shaft, bottom plate, side plate and bucket teeth, etc. The lug plate is welded on the top of the bucket, and the bucket tooth is welded on the tooth seat plate as an important part of the bucket. During the operation of the excavator, relying on the bucket teeth to loosen soil and gravel, there will be greater resistance at the bu...

AI Technical Summary

Problems solved by technology

During the operation of the excavator, relying on the bucket teeth to loosen soil and gravel, there will be greater resistance at the bucket teeth. Therefore, the excavator needs to provide greater digging force, which will easily lead to wear and fracture of the bucket teeth. Problems such as laborious operation and low work efficiency

At present, in machine work engineering, when the bucket excavates hard objects without vibration, it will generate direct load stress, which will cause excessive local stress of the bucket, resulting in premature failure and damage. The setting of the vibration device will make the bucket in contact with The vertical force generated in the vertical direction of the forward direction of the excavator reduces the impact force caused by too hard objects and reduces the service life of components
