Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of mine perforating machine, concretely is a mine perforating machine. BACKGROUND

[0002] In the field of mine exploitation, perforating operation is a very key link. Whether it is to arrange blast hole before blasting exploitation or to prepare for subsequent support, exploitation equipment installation and other work, accurate and efficient perforation directly affects the progress and quality of mine exploitation. The mine geological conditions are complex and diverse, and the rock hardness and structure are different, which puts forward very high requirements for the perforating equipment.

[0003] The traditional perforating device has many drawbacks when dealing with complex mine environments. Large perforating equipment has powerful perforating capacity, but is often large in size and complex in structure. Such equipment needs professional transport vehicles and installation and debugging teams, and its movement is extremely inconvenient in rugged and uneven mine roadways or large open-pit mining areas with large terrain undulations. For example, in some small mines or complex terrain mining points, large perforating equipment is difficult to reach the operation site, and even if it reaches the site, it cannot be used normally due to space limitations. This not only leads to low operation efficiency, but also greatly increases the exploitation cost, including equipment transportation, site transfer fees and losses due to idle equipment. Small and medium-sized perforating devices are also unsatisfactory in portability. Most small and medium-sized perforating equipment lacks reasonable mobile auxiliary design and relies only on simple rollers or manual transport. On the ground full of gravel and potholes in the mine, the rollers are easily trapped in holes or stuck by stones, and manual transport consumes a lot of manpower and is extremely inefficient. The operator needs to exert a lot of effort to overcome the ground resistance during the movement of the equipment, and also needs to pay attention to the balance of the equipment at all times to prevent the equipment from falling and being damaged, which makes the movement work on the complex ground environment in the mine extremely difficult.

[0004] In addition, the existing small and medium-sized perforating devices generally have the problem of excessive vibration during operation. The traditional power drive and reset methods used, such as spring reset, produce strong vibration during perforation. This vibration not only passes to the operator's hands, causing numbness and soreness, seriously affecting the operation experience and reducing the operator's work enthusiasm and concentration, but also damages the equipment itself. Frequent vibration can cause parts to loosen and wear out, shorten the service life of the equipment, and increase the frequency and cost of equipment maintenance. Moreover, excessive vibration can affect the accuracy of perforation, causing the drilled holes to deviate and not meeting the requirements of accurate perforation for mine exploitation. In summary, it is urgent to develop a new type of perforating machine that is portable, has little vibration and can adapt to the complex ground environment in the mine. SUMMARY
