Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of coal mine equipment, and in particular relates to a punching device for coal mining. Background Art
[0002] Coal mining is a complex and dangerous process that requires the use of various equipment to ensure safety and efficiency. Punching, as an important operation in the coal mining process, is usually used for mining tunnels, installing supports and drainage. However, traditional punching devices have some defects, the most important of which is that the angle is fixed and the punching angle cannot be adjusted according to the actual tunnel terrain, which brings certain difficulties and dangers to coal mining work.
[0003] In traditional punching devices, the fixed angle design limits its applicability in different terrain conditions. Due to the changeable terrain of coal mine tunnels, sometimes punching at different angles is required to achieve the best effect, but traditional devices cannot meet this demand. Operators often need to laboriously adjust the position of the equipment or use other tools to make up for the shortcomings of the fixed angle, which not only increases the workload but also increases the risk of accidents.
