Excavator bucket capable of swinging through gear drive and hydraulically enhancing digging force

Abstract

The invention discloses an excavator bucket capable of swinging through gear drive and hydraulically enhancing digging force. The excavator bucket comprises an excavator bucket body, an upper fixing plate, a translation rack and a semicircular gear, wherein the semicircular gear is fixedly arranged on a gear center shaft, the translation rack is meshed with the semicircular gear, and a set of first hydraulic oil cylinders are arranged at the two ends of the translation rack; a lower connecting piece is connected to the front side of the upper end of the excavator bucket body, an upper connecting piece is fixed to the front side of the lower end of the upper fixing plate, the lower connecting piece is fixedly connected to the gear center shaft, and the gear center shaft penetrates through the upper connecting piece and can rotate relative to the upper connecting piece; and the semicircular gear can be driven by the translation rack to rotate together with the gear center shaft, and meanwhile, the excavator bucket body is driven to swing. The excavator bucket can swing and can be used in more complex working conditions in actual production; the digging force is enhanced to facilitatethe development of excavation work, and the excavation efficiency is improved; and the service life of the excavator bucket can be prolonged through the optimized design of bucket teeth and a blade plate structure, and the cost is saved.

Description

technical field [0001] The invention relates to a gear-driven excavating bucket with hydraulically enhanced digging force, and optimizes the design of bucket teeth and blade plate assembly structures, belonging to the technical field of engineering excavators. Background technique [0002] The bucket is an important part of the excavator. When working, the bucket rotates up and down to realize the functions of digging and releasing materials. The up and down rotation of the bucket is mainly driven by the hydraulic cylinder on the boom. However, in the face of complex working conditions, the up and down rotation is limited, and it needs to swing left and right to expand the working space. The traditional bucket structure is difficult to meet the construction requirements. The main power of the bucket work comes from the hydraulic cylinder on the boom, so the digging force is limited and the work efficiency is low. [0003] The blade plate and bucket teeth are connected by we...
