In some detailed description of the invention, the body construction of engineering truck that the chassis that car body and car body have and walking mechanism can use common vehicle body structure or construction equipment to commonly use or the body construction after adaptability reform.
Walking mechanism can be that the actuating unit in vehicle structure drives wheel walking structure, and also can be caterpillar walking structure common in engineering truck, also can be the walking structure of the rail mounted used in constructing tunnel.Walking mechanism can self-powered mechanism, such as internal combustion engine, and motor, hydraulic motor etc., also can by other equipment tethered slidings.
In section Example, the implementation of feed mechanism as shown in Figure 1, and described feed mechanism is the first conveyer belt 21, and described first conveyer belt 21 is arranged on whitewashing cantilever 1, and the discharge port of described first conveyer belt is corresponding with the charging aperture of mechanism's feed arrangement of whitewashing.
In some embodiments, as shown in Fig. 1 ~ Fig. 7, feed arrangement is feed hopper 31.In an embodiment, it is large that feed hopper 31 can make charging aperture, the funnel-shaped structure that discharging is young, so that collect the material unloaded in the feed mechanisms 2 such as conveyer belt, the material collected flow to discharging opening by funnelform structure, and then transfers in extrusion device 32.In certain embodiments, the mechanisms such as butterfly valve can be set at the charging aperture of feed hopper 31 or discharge outlet, by switch and the aperture of valve, to control the flowing of material better.
As shown in Figure 2, whitewashing cantilever 1 can be more than a joint or two saves, in order to better whitewashing mechanism 3 be moved to the position in approach construction face, or adjust equipment construction position more neatly, cantilever 1 of whitewashing in section Example is more than two joints, stretching structure or bending structure can be had between the joint of whitewashing cantilever 1 and joint, described bending structure can by the joint of whitewashing cantilever 1 with save between be connected by articulated manner and realize bending.The stretching structure of pulp shooting machine cantilever can be realized by the mode as described in Fig. 1 ~ Fig. 3.Described pulp shooting machine cantilever comprises the first arm joint 11 and save 12 with the second arm, and described first arm joint 11 is save near the arm of equipment platform, and described second arm saves 12 and is connected with the mechanism that whitewashes.First arm joint can arrange first slide constructions such as slide rail, slide bar or chute, the second arm joint is provided with second slide construction suitable with the first slide construction, such as slide block, draw runner or slide fastener etc.First arm joint 11 is connected with the second slide construction by the first slide construction between saving 12 with the second arm, second arm joint 12 hangs on the first arm joint 11, therebetween be slidably connected along its length, simultaneously save the hydraulic cylinder that to arrange between 12 and be connected with the two respectively or winch configurations etc. at the first arm joint 11 and the second arm, by pulling of wire rope in the flexible of hydraulic cylinder or winch configurations, change the first arm joint 11 and the second arm save relative position between 12, realize the object that whitewashing cantilever stretches.When cantilever of whitewashing has the structure of 3 joints or more joint, the structure similar with such scheme still can be adopted to realize telescopic effect.
As shown in Figure 2, when cantilever of whitewashing has two joint structures, first conveyer belt also comprise to save with the first arm 11 corresponding the first arms save conveyer belt 211 and, save 12 corresponding the second arms with the second arm and save conveyer belt 212, second arm joint conveyer belt 212 is positioned at the first arm and saves below conveyer belt 211, and it is corresponding that the discharge port of the first arm joint conveyer belt and the second arm save conveyer belt 212.Material first saves conveyer belt 211 by the first arm and is delivered to the discharge port that the first arm saves conveyer belt, then drops on the second arm joint conveyer belt 212, continues to save conveyer belt 212 by the second arm and be delivered to feed arrangement.
In other embodiment, described whitewashing mechanism 3 can move relative to whitewashing cantilever 1, and its object is also the position in order to adjust whitewashing mechanism 3 flexibly.In order to coordinate the movement relative to cantilever of whitewashing mechanism, when described feed mechanism is the first conveyer belt, whitewashing cantilever arranges a material baffle, described material baffle fixes with whitewashing mechanism, with whitewashing, mechanism moves, and when the mechanism that whitewashes moves to a certain position, material baffle also moves to relevant position, material baffle lower edge is positioned at above the upper surface of the first conveyer belt, by material baffle, the material on the first conveyer belt is blocked also directing material and flows in feed arrangement.
More freedom of movement is had in order to allow whitewashing cantilever 1, in some embodiments, as shown in Figure 1, spouting plant is provided with platform rotating mechanism, described platform rotating mechanism driving arrangement platform 9 rotates relative to chassis 41, and arrow A 1 shown in Fig. 1 has indicated the direction rotated.Platform rotating mechanism can comprise actuating unit and transmission mechanism, and described actuating unit can be motor or internal combustion engine, and described transmission mechanism can be gear or belt pulley etc.
Conveniently material loading, in certain embodiments, as shown in Figure 3, described spouting plant is provided with the second conveyer belt 22, and described second conveyer belt 22 fixes with chassis of vehicle body 41, and the discharge port of the second conveyer belt 22 is corresponding with the feeding port of the first conveyer belt 21.
Coordinate the embodiment scheme with platform rotating mechanism, due to the needs according to shotcrete construction, equipment platform may need to rotate different angles, therefore the first conveyer belt on whitewashing cantilever is driven to rotate, conveniently material loading, equipment is provided with the second conveyer belt fixed with car body, no matter can how to be rotated by equipment platform by the second conveyer belt, second conveyer belt all can stably the position feeding of self-retaining convey materials, then the mode of material conveyer belt is transported on the first conveyer belt.In order to ensure the blanking effect of the second conveyer belt, hopper construction can be set at the discharge port of the second conveyer belt, effectively to gather collection material.
Conveyer belt mode is adopted to be avoid material transport in the duct and condense to one of beneficial effect of whitewashing mechanism feed.
