Description

Technical Field

[0001] The utility model relates to the technical field of mining equipment, in particular to a mining drill with an adjustable drill bit. Background Technique

[0002] Mining equipment mainly refers to the general term of various special equipment used in the production processes of mines such as coal, ferrous metals, and non-ferrous metals, including excavation, screening, transportation, and other equipment. Among them, mining jumbo is a commonly used ore collection and mine drilling equipment, which is widely used in the fields of coal mine exploration, mining, and research.

[0003] The existing mining jumbo has the following disadvantages in the use process: The supporting drill bit of the existing mining jumbo is generally of a fixed structure. During the drilling process, if it is found that the length of the drill bit does not reach the required depth, the entire drill bit needs to be withdrawn and replaced with a longer drill bit of a different specification. This process requires a series of steps for the drill rig, such as resetting, changing the drill, and re-driving, which is cumbersome and time-consuming, and the drill bit cannot be adjusted conveniently. Therefore, we propose a mining drill with an adjustable drill bit. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a mining drill with an adjustable drill bit. Through the adjustment mechanism arranged on the top of the jumbo, the combined length of the drill bit can be adjusted when needed to meet the drilling requirements, and there is no need to replace the entire drill bit assembly, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
