A mining built-in scraper type bucket rear unloading loader

Abstract

The invention relates to a mining built-in scraper type bucket rear-unloading loader which is composed of a vehicle body and a track. The mining built-in scraper type bucket rear-unloading loader further comprises a bucket mechanism and a built-in scraper machine. The bucket mechanism comprises a bucket, a material unloading plate, a material unloading plate control oil cylinder, a small movable arm, a small movable arm control oil cylinder, a large movable arm and a large movable arm control oil cylinder. The working space needed by the bucket mechanism is very small, and the mining built-in scraper type bucket rear-unloading loader can carry out work in the space where a common loader can enter.

Description

technical field [0001] The invention relates to the field of loaders, in particular to a mining built-in scraper type bucket rear discharge loader. Background technique [0002] Roadway excavation is mainly divided into five major processes, rock breaking, rock loading, rock transportation, support and track laying. Among them, the loading and transportation of rocks is the heaviest and most time-consuming process, which generally accounts for 35%-50% of the excavation cycle time. Therefore, doing a good job of loading will greatly reduce the time spent in excavating the roadway and improve efficiency. The efficiency of rock loading is closely related to the performance of the loader. At present, underground loaders mainly include bucket loaders, rake loaders, crab claw loaders and vertical claw loaders. Among them, the bucket loader has a large bucket insertion force, a large bucket capacity, and high efficiency. Its unloading methods include side dumping and lifting afte...

Problems solved by technology

Although the side unloading type (such as: a multifunctional side unloading pilot control bucket for wheel loaders, application date: 2012.12.25, announcement number: CN203080564U) can reduce space requirements compared with ordinary unloading methods, but this type The unloading method still requires a double-track roadway (one track for the loader and one track for the transportation equipment) when used underground, which requires a large cross-sectional area of ​​the roadway and cannot meet the loading and unloading requirements of small-section roadways

Lifting rear unloading type (such as: rear unloading loader, application date: 2007.5.8, announcement number: CN201007008Y) requires a large height for loading and unloading space, large roadway excavation area, high excavation and support costs, and in There is a danger of the load falling during the lifting process, which brings great safety hazards to personnel and equipment, and cannot meet the requirements of the small underground space.

Moreover, when operating this type of equipment, the driver needs to turn around repeatedly to observe the working conditions of the bucket on the front and rear sides of the loader. The driver's work intensity is very high and he is prone to fatigue.
