Hydraulic excavator spiral bucket

Abstract

A hydraulic excavator spiral bucket comprises a material storage barrel fixed on guiding posts and a fixed top plate, wherein the fixed top plate is fixedly connected with at least two guiding posts, an extending arm of an excavator is fixed on the fixed top plate, the material storage barrel is connected with a fixing sleeve on the upper end in a sliding node, a screw which is driven by a variable hydraulic fluid motor is additionally arranged, a fine screw thread is arranged on the upper portion of the screw, a big screw thread is arranged on the lower portion, the screw penetrates through the material storage barrel, the fine screw thread on the upper portion is meshed with an inner screw thread of the fixing sleeve on the upper end to realize lifting the screw, the variable hydraulic fluid motor is sleeved on the guiding posts and can move upwards and downwards along the guiding posts, and a liquid control braking switch is arranged on the top ends of the fixing sleeve and the bucket material storage barrel. The hydraulic excavator spiral bucket of the invention has big single bucket volume and high digging efficiency, and is applicable to the digging operation of various geological configuration complex working conditions.

Description

technical field [0001] The invention relates to a hydraulic excavator screw type bucket. Background technique [0002] Existing hydraulic excavator buckets have a single function, and the excavated objects are easy to scatter during the excavation process, so it is difficult to realize the full load of the bucket, and the capacity of a single bucket is small, which not only wastes energy, but also causes low efficiency of the excavator; especially, it cannot adapt to In the working environment with hard geological conditions, when encountering complex geological structures, it is necessary to use other equipment to complete the excavation task. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings of the prior art and provide a hydraulic excavator screw type bucket with compact structure, large single bucket capacity and high digging efficiency. [0004] A further object of the present invention is to provide a hydraulic ex...
