Bucket and mining excavator

Abstract

The bucket comprises a bucket body, the bucket body is provided with a containing groove used for containing materials, the containing groove is provided with a front opening used for receiving the materials and a bottom opening used for discharging the materials, and bucket teeth are arranged at the position, at the lower end of the front opening, of the bucket body; the bucket bottom door is mounted at one end of the bottom opening of the bucket main body and can pivotally move between an open position and a closed position relative to the bucket main body so as to open and close the bottom opening; the balance beam comprises a body and at least two rope grooves, the body is hinged to the upper end of the front opening of the bucket body, and the at least two rope grooves are symmetrically formed in the two sides of the body and used for being connected with a lifting steel wire rope of the mining excavator. The working range of the bucket can be widened, the unloading height of the excavator is increased, the problems that when the excavator is matched with a crushing station of the same specification to work, bucket bottom impact is large, and bucket opening is difficult are solved, and the weight of the bucket is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of excavators, in particular to a bucket and a mining excavator. Background technique [0002] Mechanical shovel excavator, also known as mining excavator, is a special equipment used for open-pit mining. Existing mining excavators mainly include rotary platforms, A-frames, booms, and sticks , bucket, pushing device, hoisting device, tension rope and hoisting wire rope, etc. Among them, the bucket is the key component of the mining excavator, which is directly used for excavating materials. In the existing mining excavator, the upper part of the bucket is connected with the stick, the upper part of the slot in the front of the bucket is connected with the lifting wire rope through the lifting beam, the bottom of the bucket is provided with an opening, and the bottom is installed with a bucket bottom, which can It rotates under the control of the set closing mechanism to open or close the bottom opening of t...

AI Technical Summary

Problems solved by technology

[0003] When the existing mining excavator is in use, the working range and unloading height composed of the bucket structure, arm and lifting wire rope must be reasonably matched with the equipment that cooperates with the work. If the working range and unloading height are not enough, the bucket loading will be caused. The material is difficult, the bucket bottom is opened more times, and the bottom of the bucket has a large impact on the bucket body when the bucket is opened, which leads to low working efficiency of the equipment, which cannot meet the planned output, and cracks in the bucket bottom or bucket body

[0004] Existing mining excavators are usually equipped with mine cars, and their working range and unloading height can be reasonably matched with mine cars; however, in some working conditions, mining excavators need to work with self-moving crushing stations. Since the height of the receiving hopper of the self-moving crushing station of the same specification is about 1.5 meters higher than the height of the mine car body, when the existing mining excavator works with the crushing station, there is a large impact on the bottom of the bucket when the bucket is opened. , Difficulty in fighting, etc.
