Problems solved by technology

The length of the stick of the existing excavation machinery is invariable, and the excavation depth is also invariable during construction; if the excavation depth is to be increased, only a larger type of excavator must be replaced, which not only increases the construction cost, but also affects the construction progress

Abstract

The present invention discloses a flexible dipper device of excavating machinery, comprising an upper dipper, a lower dipper and a flexible cylinder; wherein the upper dipper is sheathed in the lower dipper, the head part of a cylinder rod of the flexible cylinder is articulated with the middle part of the upper dipper, a rear overhang lug of the flexible cylinder is articulated with the rear end of the lower dipper, the inside of the flexible dipper device is also provided with an upper dipper guide travel mechanism and the back side of the flexible dipper device is provided with an upper dipper locking mechanism. When the upper dipper is locked, a locking plate is arranged in a locking seat of the upper dipper and the locking seat is articulated with the locking plate. Guide track pressure plates are respectively fixedly arranged at the two longitudinal inner sides of the lower dipper, supporting cushion blocks are respectively arranged at the inside of the bottom of the lower dipper and the upper dipper is embedded between the supporting cushion blocks and compacting cushion blocks by the guide track at the two sides thereof. By controlling a handle, the upper dipper can be stretch out and drawn back outwards within a certain degree in the lower dipper under the driving of the flexible cylinder, thereby expanding excavation range of a loader digger.

Description

technical field [0001] The invention relates to a stick device of an excavating machine, in particular to a device capable of changing the length of the stick, and belongs to the technical field of engineering machinery. Background technique [0002] At present, with the rapid development of the national economy, the scale of basic construction is getting larger and larger. Whether it is high-speed railway, highway, port and other construction projects, or industry, agriculture, water conservancy projects, municipal engineering, residential construction, etc., it is inseparable from excavation. As a kind of multi-functional construction machinery, excavator is used more and more widely. The length of the stick of the existing excavation machinery is invariable, and the excavation depth is also invariable during construction; if the excavation depth is to be increased, only a larger type of excavator must be replaced, which not only increases the construction cost, but also a...
