Other advantageous effects of the present invention will be further described with reference to the following embodiments.
Drawings
The invention will be further described with reference to the following figures and examples:
fig. 1 is a front view of the present invention;
FIG. 2 is a top view of FIG. 1;
FIG. 3 is a top isometric view of FIG. 1;
fig. 4 is a bottom isometric view of fig. 1.
Detailed Description
As shown in the figure: the split type automatic feeding guniting unit vehicle suitable for the small tunnel in the embodiment comprises a guniting unit and a vehicle for transporting the guniting unit, and a driver seat 1 is arranged in front of the vehicle. The guniting machine set comprises a guniting machine set body and a guniting machine frame 5 used for supporting the guniting machine set body, wherein the guniting machine frame 5 is arranged on a chassis 9 of the vehicle and is detachably connected with the chassis 9 of the vehicle, corresponding pin shaft holes can be arranged on the machine frame 5 and the chassis 9 of the vehicle, the machine frame is fixed by a pin shaft 10, and the machine frame can be detached by pulling out the pin shaft 10; and a frame hydraulic prop used for supporting the whole guniting machine set on the ground is arranged on the guniting frame 5.
