Low-speed high-load excavating construction machine with butter distribution

Abstract

The invention discloses a low-speed high-load excavating construction machine with butter distribution. The low-speed high-load excavating construction machine structurally comprises lubricating arms,a bucket, a shovel arm control rod, an oil storage device, a small arm, a small arm drive rod, a large arm, large arm drive rods, a control machine body and moving wheels. The two lubricating arms are arranged and are uniformly fixed on two sides of a movable shaft at the top end of the bucket. The end head at the bottom of the shovel arm control rod is fixed in the middle of the bucket. The bottom of the oil storage device is connected with an oil valve of each lubricating arm through an oil pipe. In summary, after improvement, a power shaft rod is lubricated through a plurality of oil passages, so that the power shaft rod is covered by butter in the process of frequent digging actions; and meanwhile, impurities in the power shaft rod can be brought out of the squeezed butter in a mode of perfusion from inside to outside, so that the situation that the adhesion capability of butter is reduced due to excessive impurities is avoided, and the contact performance between butter and joints is improved to reduce wear.

Description

technical field [0001] The invention relates to a construction machine, in particular, a low-speed and high-load excavation construction machine with butter distribution. Background technique [0002] Excavators, also known as backhoes, are construction machines that use buckets to excavate materials higher or lower than the bearing surface, and load them into transport vehicles or unload them to stockyards. They are widely used in construction units to excavate construction waste and For work such as digging, there will be some problems due to the heavy load work for a long time: [0003] When the excavator is working, the upper joints of the bucket move relative to each other. The pin shafts and bushings of these parts are always in friction when they are working, and because of the heavy load of the excavator, the force on these parts is also very large, and it is necessary to add butter regularly. Lubricate, but because the butter is very viscous, it is easy to graduall...

AI Technical Summary

Problems solved by technology

[0003] When the excavator is working, the upper joints of the bucket move relative to each other. The pin shafts and bushings of these parts are always in friction when they are working, and because of the heavy load of the excavator, the force on these parts is also very large, and it is necessary to add butter regularly. Lubricate, but because the butter is very viscous, it is easy to gradually harden and fall off with the dust structure during the construction process. It needs to be filled with butter every day to facilitate the maintenance of the excavator bucket
