In other embodiments of the heading machine: the present embodiment provides different ways of connecting the first upper and lower telescoping mechanism to the first ramming mass, unlike embodiment 1 in which the first upper and lower telescoping mechanism is normally articulated with the first ramming mass about an articulation axis.
In other embodiments of the heading machine: this embodiment provides a different construction of the end piece, which differs from embodiment 1 in that the end piece is of a frame construction, and in that the second ram body can likewise be retracted into the end piece. Of course, in other embodiments, the end piece can also be a plate-like structure, without the second ram body retracting into the end piece.
In other embodiments of the heading machine: the present embodiment provides a different construction of the first ramming body, which differs from embodiment 1 in that the first ramming body is a frame structure, and the end pieces and the second ramming body can likewise be retracted into the first ramming body. Of course, in other embodiments, the first ram body could be a unitary block structure, except that the left and right ends are recessed to allow the end pieces and the second ram body to retract into the first ram body.
In other embodiments of the heading machine: the present embodiment provides different structural compositions of the muck ramming device, unlike embodiment 1, the left and right ends of the first ramming body are not provided with the transverse telescopic mechanisms, and of course, the end members, the second up-down telescopic mechanisms, the second ramming body and the like are not provided.
In other embodiments of the heading machine: the present embodiment provides a different form of the muck ramming device, unlike embodiment 1 in which the muck ramming device is a swing lever type ramming device, in which case the first up-down telescoping mechanism is not included.
In other embodiments of the heading machine: the first upper and lower telescopic mechanisms, the second upper and lower telescopic mechanisms and the transverse telescopic mechanisms are all air cylinders.
In other embodiments of the heading machine: when the road formed by the compacted dregs can meet the demands of traffic and personnel in and out, an injection device is not arranged, namely, the hardened material is not injected on the surface of the compacted dregs.
The embodiment of the main machine of the heading machine with the bottom paving function comprises the following steps: the specific structure of the host machine of the heading machine with the bedding function is the same as that of the host machine in any embodiment of the heading machine, and will not be repeated here.
The above description is only a preferred embodiment of the present invention, and the patent protection scope of the present invention is defined by the claims, and all equivalent structural changes made by the specification and the drawings of the present invention should be included in the protection scope of the present invention.
