The operation process of underground loader is completed by hydraulic control device. It is a device used to overcome the resistance of the cut material, and complete a series of work, such as inserting the material pile, scooping the material, lifting and unloading the material. What are the important parts of it? Let's see:

1、快换装置：主要针对工作场地中存在多种物料需要装卸的工作环境，驾驶员坐在驾驶室内即可对工作装置进行快速更换，使用方便、作业效率高，可更换的工作装置有：铲斗、夹木叉等。

1. Quick change device: it is mainly aimed at the working environment where there are many materials to be loaded and unloaded in the workplace. The driver can quickly change the working device by sitting in the cab. It is easy to use and has high operation efficiency. The replaceable working devices include bucket, wooden fork, etc.

2、抓草斗：主要应用于植物秸秆等抓取，具有开口大、压实紧、抓草效率高等特点。

2. Grass grabbing bucket: it is mainly used for grabbing plant straw. It has the characteristics of large opening, tight compaction and high grass grabbing efficiency.

3、加大斗：在标准机型配置的基础上，加大铲斗容量，以提高工作效率，以满足比重较轻物料的铲装，如：煤炭等。

3. Bigger bucket: on the basis of standard model configuration, increase the bucket capacity to improve work efficiency and meet the shovel loading of materials with light proportion, such as coal, etc.

4、岩石：主要针对装卸岩石工况，铲斗的斗臂板、支撑板斗进行了加强，并配备了高耐磨的副刀板、高耐磨精铸斗齿，从而提高了整个铲斗的使用寿命。

4. Rock King: mainly for rock loading and unloading conditions, the bucket arm plate and support plate of the bucket are strengthened, and equipped with high wear-resistant auxiliary knife plate and high wear-resistant precision casting bucket teeth, so as to improve the service life of the whole bucket.

5、高卸黑金：主要用来满足货车日益增高的围栏高度，对于煤炭等比重较低的物料，即可满足高卸载，又可满足大装载量，大大提高工作效率。

5. High unloading Black Gold King: it is mainly used to meet the increasing fence height of trucks. For materials with low specific weight such as coal, it can not only meet high unloading, but also meet large loading capacity and greatly improve work efficiency.

井下装载机是一种用途十分广泛的工程机械，它被广泛应用于建筑、公路、矿山及国防等工程中，对加快工程建设速度、减轻劳动强度、降低工程成本具有重要作用。

Underground loader is a kind of widely used engineering machinery. It is widely used in construction, highway, mining and national defense projects. It plays an important role in speeding up project construction, reducing labor intensity and reducing project cost.
