Problems solved by technology

These excavators have difficulty changing the direction of the roadway, as this often requires changing the orientation of the entire drilling machine
This can be a complex task as it requires maneuvering the drilling machine within the confines of the excavated roadway
Furthermore, the cutting mechanism of conventional drilling machines can generate high stresses, reducing the operating life of the drilling machine and requiring frequent maintenance

Embodiment Construction

[0019] figure 1 and 2 An underground boring machine 10 is shown for engaging a wall (not shown) to create a driveway or entry in the wall. The drilling machine 10 includes a vehicle frame 18 , a boom 22 , a drilling tool head 26 , a pair of forming tool heads 30 , a stabilization system 34 and a material delivery system 38 . The frame 18 defines a frame axis 46 ( image 3 ) and includes a pair of tracks 50 for supporting the vehicle frame 18 on a floor or support surface. In other embodiments, the frame 18 may include a hydraulic travel mechanism or a hydraulic ejector mechanism, and may include more or fewer forming tool heads 30 . The frame 18 may also include an additional pump station and power pack (not shown) for providing primary drive power to the drilling tool head 26 and forming tool head 30 .

[0020] Such as image 3 and 4 As shown, the cantilever 22 includes a first end 58 ( Figure 4 ), the second end 62, the first part 66 near the first end 58 ( Figure ...

Abstract

An underground boring machine includes a vehicle frame, a boom, and a boring cutter head. The boom includes a first end coupled to the vehicle frame and a second end. The boring cutter head includes a rotary joint, a first arm, and a second arm angularly spaced apart from the first arm. The rotary joint defines an axis of rotation and supports the boring cutter head for rotation with respect to the second end of the boom. The first arm includes a first end coupled to the rotary joint, a second end, and at least one disc cutter coupled to the first arm and oriented to engage the wall. The first arm extends from the first end toward the second end in a plane that is perpendicular to the axis of rotation. The second arm includes a first end coupled to the rotary joint, a second end, and at least one disc cutter coupled to the second arm and oriented to engage the wall. The second arm extends from the first end toward the second end in a plane that is perpendicular to the axis of rotation.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 61 / 370,342, filed August 3, 2010, the entire contents of which are hereby incorporated by reference. Background technique [0003] The present invention relates to mining equipment, and in particular to underground drilling machines. [0004] Conventional underground excavators provide rotating cutter heads to create entrances or tunnels in walls of material. The cutter head includes a cutting mechanism for breaking up material from the wall. These excavators have difficulty changing the direction of the roadway as this usually requires changing the orientation of the entire drilling machine. This can be a complex task as it requires maneuvering the drilling machine within the confines of excavating the roadway. Furthermore, the cutting mechanism of conventional drilling machines can generate high stresses, reducing the operating life of the drilling m...
