Problems solved by technology

[0003] When the roadheader in the prior art is in use, the drill bit needs to be raised or lowered through the expansion and contraction of the output shaft of the cylinder, so that the drill bit can break rocks of different heights, but in this way, the drill bit is raised to After a certain height, the drill bit can only be broken in one direction, which makes it take a long time for the drill bit to break the rock, and also breaks around the part drilled into the rock, thus achieving the effect of breaking a large amount of rock. Its work efficiency is low, and the time for crushing rocks is long

Embodiment 1

[0031] The embodiment is basically as attached figure 1 Shown: a kind of coal mine tunneling device, comprises load-bearing base 8, walking belt 1 installed on load-bearing base 8, drill bit 12 and the power part that drives drill bit 12 to rotate, and walking belt 1 is crawler belt in the prior art, does not describe here To repeat, the load-bearing base 8 is connected with a fixed box 2, the fixed box 2 is hinged with a control lever 4, and the end of the control lever 4 away from the fixed box 2 is fixedly connected with a drive box 9 by bolts, and the drive box 9 is provided with a drive box for driving the drill bit. 12 reciprocating drive parts, the fixed box 2 is hinged with the control cylinder 5, and the output shaft of the control cylinder 5 is hinged with the drive box 9.

[0032] Such as figure 2 As shown, in this embodiment, the driver includes a mounting column 14 and a rotating plate 13, the mounting column 14 is welded and fixed to the fixed box 2, and the mo...

Embodiment 2

[0042] Such as image 3 As shown, a coal mine excavation device differs from Embodiment 1 in that: the fixed box 2 is provided with a conveyor belt 7 for transporting crushed stones, the fixed box 2 is fixed with a shovel 6 by bolts, and the left end of the shovel 6 is connected to the Conveyor belt 7 links to each other, and shovel plate 6 is positioned at the same side of fixed case 2 with drill bit 12, and conveyer belt 7 adopts the conveyer belt in the prior art, and shovel plate 6 has the inclined-plane that inclines downward.

[0043] to combine Figure 4 As shown, two spatulas are rotationally connected on the slope of the spatula 6. In this embodiment, the spatulas all include a rotating rod 25 and a plurality of blades 24. A shoveling motor (not shown) that drives the rotating rod 25 to rotate is provided inside, and a plurality of blades 24 are evenly distributed along the circumferential direction of the rotating rod 25 .

[0044] In practical application, when th...

Embodiment 3

[0046] Such as Figure 5 Shown, a kind of coal mine excavation device, and the difference of embodiment one is: in the present embodiment, the top of fixed box 2 is connected with temporary supporting device, and in the present embodiment, temporary supporting device comprises base plate 26 and driving unit, and base plate 26 is vertically welded and fixed with a guide plate 28, the guide plate 28 is a rectangular plate-shaped structure, and the vertical slide on the guide plate 28 is connected with an installation box 29. In the present embodiment, the guide plate 28 is vertically provided with a strip groove, and the installation box 29 rear side ( figure 1 Angle of view) a slider 17 (not shown) is welded and fixed, and the slider 17 is inserted into the bar-shaped groove and vertically slides and fits with the bar-shaped groove.

[0047] The drive unit is used to drive the installation box 29 to reciprocate and slide vertically. In this embodiment, there are two drive unit...

Abstract

The invention relates to the technical field of coal mine equipment, and discloses a coal mine tunneling device. The coal mine tunneling device comprises a bearing base, a walking belt installed on the bearing base, a drill bit and a power piece for driving the drill bit to rotate, a fixing box is connected to the bearing base, a control rod is hinged to the fixing box, the end, away from the fixing box, of the control rod is connected with a driving box, a driving piece used for driving the drill bit to swing in a reciprocating mode is arranged in the driving box, a control air cylinder is hinged to the fixing box, and an output shaft of the control air cylinder is hinged to the driving box. The crushing effect of the drill bit can be improved, and the crushing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of coal mine equipment, in particular to a coal mine driving device. Background technique [0002] The roadheader is a machine used to dig a straight underground roadway. The roadheader is divided into an open type roadheader and a shield type roadheader. It is mainly composed of a walking mechanism, a working mechanism, a loading mechanism and a reloading mechanism. Pushing forward, the drill bit in the working mechanism continuously breaks the rock. [0003] When the roadheader in the prior art is in use, the drill bit needs to be raised or lowered through the expansion and contraction of the output shaft of the cylinder, so that the drill bit can break rocks of different heights, but in this way, the drill bit is raised to After a certain height, the drill bit can only be broken in one direction, which makes it take a long time for the drill bit to break the rock, and also breaks around the part drilled ...
