Description

Technical Field

[0001] The utility model relates to the technical field of scrapers, in particular to a centralized lubrication system for underground scrapers. Background Art

[0002] Underground scraper, also known as underground loader, is a kind of mechanical equipment that moves on tires and relies on the bucket at the front of the fuselage for loading, unloading and transportation. At present, the rotation and other moving parts of the loader are affected by harsh working conditions such as moisture, dust and corrosion. If lubrication is not timely, it is easy to rust, wear and even damage. Through research, it is not difficult to find that the current lubrication methods of loaders are divided into manual lubrication and automatic lubrication.

[0003] Manual lubrication means lubricating the whole machine with a manual lubrication pump at the prescribed maintenance time. The disadvantages of this lubrication method are:

[0004] 1. It is necessary to stop the machine and lubricate each lubrication point one by one, which reduces the efficiency of the loader.

[0005] 2. There are more than 20 lubrication points on the loader. It is time-consuming and laborious to lubricate them one by one. In addition, some lubrication points, such as the hinge points of the rear axle swing frame and the hinge points of the steering cylinder, are relatively hidden and are prone to lubrication leakage.

[0006] 3. Each lubrication point has a different demand for lubricating oil, and it is difficult to accurately control it during the actual oiling process, which can easily lead to over-lubrication or insufficient lubrication.

[0007] Among them, automatic lubrication currently mainly adopts a centralized automatic lubrication system. Although automatic lubrication can be achieved, when replenishing the lubricating oil, it is still necessary to replenish the grease from the lubricating grease barrel to the storage tank in the device through a grease feeder. Not only is the workload large, but the work efficiency is also low. Utility Model Content
