Description
Technical Field
[0001] The utility model relates to the technical field of mining equipment, and particularly relates to a mining roadheader. Background Art
[0002] When mining minerals, a mining roadheading device is generally used for mining roadheading operations. The roadheading bit of a boom-type mining roadheader is arranged on a movable boom. During use, the position of the roadheading bit is controlled by adjusting the boom, so as to realize mining roadheading at different positions. It is relatively flexible and convenient to use, and is a common mining roadheading device.
[0003] During the process of mineral mining, the mine wall and roof near the mining roadheading device are affected by the vibration of the roadheading bit, and crushed stones will fall, and there is a certain risk of collapse. In order to improve the safety of mining roadheading, a temporary support structure is generally installed above the mining roadheading device to temporarily support the roof and prevent large-scale collapse.
[0004] However, although installing a temporary support structure can increase the structural stability of the roof, the temporary support structure cannot block small-sized crushed stones, and the crushed stones on the roof will still directly fall onto the boom. On the one hand, the crushed stones have the risk of damaging the equipment. On the other hand, when the number of crushed stones is large, it is easy to jam the mechanical structure at the front end of the roadheader, resulting in the operation failure of the mining roadheading device. Therefore, during the existing mining operation, it is necessary to often suspend the mining roadheading work and manually clean the crushed stones on the mining roadheading device. The cleaning process is rather troublesome, resulting in low efficiency of the mining roadheading work. Summary of the Utility Model
[0005] Aiming at the technical problem that during the existing mineral mining process, crushed stones will fall onto the boom, there are risks of damaging the equipment and jamming the mechanical structure at the front end of the roadheader, and manual cleaning is required, resulting in low efficiency of the mining roadheading work, the utility model provides a mining roadheader, which can block and guide the discharged crushed stones falling from the roof, greatly reduce the crushed stones directly falling onto the boom, reduce the risk of the crushed stones damaging the boom or jamming the mechanical structure at the front end of the roadheader, and improve the work efficiency and safety of mining roadheading.
