Embodiment Construction

[0016] From figure 1 and figure 2 It can be seen from the figure that the present invention is applicable to the cutter head of hard rock mining, including the rotary shaft hole 1, the cutter head frame 2, the rock breaking roller 3, and the cutter head frame 2 is arranged with many installation grooves 4, and the rock breaking roller 3 is respectively installed in it. The rock-breaking roller 3 can adopt a hob or a gear hob or a toothed wheel, and can also be used in combination among the hob, the hobbed tooth, and the toothed wheel. The installation groove 4 is divided into several installation groove groups 41 along the cutterhead frame circumferential direction, and each installation groove group has two installation grooves respectively in the axial direction, and a rock breaking roller is installed in each installation groove. The installation grooves in the two adjacent installation groove groups have different axial positions to ensure that the rock breaking roller ...

Abstract

The invention discloses a cutterhead suitable for hard rock mining and a hard rock mining method.The cutterhead comprises a rotary shaft hole used for receiving radial driving force, a cutterhead frame and a rock breaking roller, the rock breaking roller is installed on the cutterhead frame, and the arrangement direction of the rock breaking roller meets the requirement that the rock breaking roller breaks rock and is suitable for radial propelling. The hard rock mining method using the cutterhead is a method that the cutterhead is propelled in the radial direction. The cutterhead structure can form an ultra-large high-strength disc type structure, and the cutterhead is driven by the large-torque hydraulic motor to ensure that the cutterhead has enough rotation torque during rock breaking work; and through reasonable arrangement of the rock breaking rollers, it is guaranteed that the rock breaking rollers evenly cut the rock surface when the cutter head rotates, it is guaranteed that the overall stress of the cutter head is average, meanwhile, it is guaranteed that stress in the rock mass is balanced, the optimal rock breaking effect is achieved, rocks with the rock hardness f larger than or equal to 8 can be cut, continuous rock breaking operation can be achieved, and the rock breaking device can be used for intelligent equipment so as to achieve intelligent efficient excavation.

Description

technical field [0001] The invention relates to the technical field of underground mine mining engineering, and more specifically relates to a cutter head suitable for hard rock mining and a hard rock mining method. Background technique [0002] For the mining of hard rock, due to the high hardness of the ore rock, the drilling and blasting method is generally used for mining. First, drill holes are drilled with drill pipes, and then explosives are installed in the blast holes for mining. This mining method has problems such as poor safety conditions and scattered and discontinuous operation links. Today, with the rapid development of intelligent equipment, the mining of hard rock mines has been stuck in the traditional drilling and blasting mining method. Therefore, how to realize safe and continuous mining of hard rock mines is an urgent problem to be solved. Contents of the invention [0003] An object of the present invention is to provide a cutter head suitable for h...
