In section Example feed mechanism realization method as shown in Figure 1, the feed mechanism be the first conveyer belt 21, institute The first conveyer belt 21 is stated to be set on whitewashing cantilever 1, the discharge port of first conveyer belt and whitewashing mechanism feeding equipment into Material mouth is corresponding.
In some embodiments, as shown in Fig. 1~Fig. 7, feeding equipment is feed hopper 31.In embodiment, feed hopper 31 It can make that feed inlet is big, the small funnel-shaped structure of discharge port, in order to collect the object unloaded in the feed mechanisms such as conveyer belt 2 Material, the material being collected into flow to discharge port by funnelform structure, and then is transferred in extrusion device 32.In certain implementations In example, can the mechanisms such as butterfly valve be set in the feed inlet or discharge outlet of feed hopper 31, by the switch and aperture of valve, with The preferably flowing of control material.
As shown in Fig. 2, whitewashing cantilever 1 can be a section or two sections or more, connect to preferably be moved to whitewashing mechanism 3 The position of nearly construction surface, or adjusting device construction location for greater flexibility, whitewashing cantilever 1 is two sections or more, spray in section Example Can have stretching structure or bending structure, the bending structure that can pass through cantilever 1 of whitewashing between the section and section of slurry cantilever 1 It realizes and bends by articulated manner connects between section and section.The stretching structure of pulp shooting machine cantilever can pass through such as Fig. 1~Fig. 3 institutes The mode stated is realized.The pulp shooting machine cantilever includes the first arm joint 11 and the second arm joint 12, and first arm joint 11 is close sets The arm joint of standby platform, second arm joint 12 are connect with whitewashing mechanism.Sliding rail, slide bar or sliding slot etc. can be set in the first arm joint First slide construction is provided with the second slide construction compatible with the first slide construction, such as sliding block, draw runner in the second arm joint Or slide fastener etc..It is attached by the first slide construction and the second slide construction between first arm joint 11 and the second arm joint 12, the Two arm joints 12 are hung in the first arm joint 11, are slidably connected along its length therebetween, while in the first arm joint 11 and second The hydraulic cylinder being connected respectively with the two or winch configurations etc. are set between arm joint 12, pass through the flexible or winch configurations of hydraulic cylinder The pulling of middle steel wire rope realizes what whitewashing cantilever stretched to change the relative position between the first arm joint 11 and the second arm joint 12 Purpose.When cantilever of whitewashing has the structure of 3 sections or more section, the structure realization similar with said program still may be used and stretch Contracting effect.
As shown in Fig. 2, when cantilever of whitewashing has two-section structure, the first conveyer belt also includes corresponding with the first arm joint 11 The first arm joint conveyer belt 211 and, second arm joint conveyer belt corresponding with the second arm joint 12 212, the second arm joint conveyer belt 212 are located at 211 lower section of the first arm joint conveyer belt, and the discharge port of the first arm joint conveyer belt is corresponding with the second arm joint conveyer belt 212.Object Material is first delivered to the discharge port of the first arm joint conveyer belt by the first arm joint conveyer belt 211, is later fallen into the second arm joint conveyer belt On 212, continue to be delivered to feeding equipment by the second arm joint conveyer belt 212.
In other embodiments, the whitewashing mechanism 3 can relative to whitewashing cantilever 1 move, purpose also for The position of whitewashing mechanism 3 can be adjusted flexibly.It is the to coordinate the movement relative to cantilever of whitewashing mechanism, the feed mechanism When one conveyer belt, a material baffle is set on whitewashing cantilever, the material baffle is mutually fixed with whitewashing mechanism, with whitewashing mechanism Mobile, when the mechanism that whitewashes is moved to a certain position, material baffle also is moved into corresponding position, and material baffle lower edge is located at first Above the upper surface of conveyer belt, the material on the first conveyer belt is blocked by material baffle and directing material is flowed into charging and filled In setting.
In order to allow whitewashing cantilever 1 to have more freedom of movement, in some embodiments, as shown in Figure 1, spouting plant is set There are platform rotating mechanism, the platform rotating mechanism driving equipment platform 9 to be rotated relative to chassis 41, the mark of arrow A1 shown in Fig. 1 Show the direction of rotation.Platform rotating mechanism may include actuating unit and transmission mechanism, and the actuating unit can be electricity Motivation or internal combustion engine, the transmission mechanism can be gear or belt pulley etc..
In order to facilitate feeding, in certain embodiments, as shown in figure 3, the spouting plant is equipped with the second conveyer belt 22, institute It states the second conveyer belt 22 to fix with 41 phase of chassis of vehicle body, the feeding port phase of the discharge port of the second conveyer belt 22 and the first conveyer belt 21 It is corresponding.
Coordinate the example scheme with platform rotating mechanism, due to the needs according to shotcrete construction, equipment platform may It needs to rotate different angles, therefore drives the first conveyer belt rotation on whitewashing cantilever, in order to facilitate feeding, equipment is provided with With mutually fixed second conveyer belt of car body, no matter how can be rotated with equipment platform by the second conveyer belt, the second conveyer belt is equal Steadily the position feeding of self-retaining and material can be conveyed, the mode of material conveyer belt is then transported to the first conveyer belt On.In order to ensure the blanking effect of the second conveyer belt, can hopper construction be set in the discharge port of the second conveyer belt, with effectively poly- Hold together collection material.
It is that material is avoided to transport and coagulate in the duct to one of the advantageous effect of whitewashing mechanism feed using conveyer belt mode Knot.
For the ease of adding accelerator, the spouting plant is additionally provided with accelerator supply equipment, and the accelerator supply is set Standby discharge port is located on the feeding path of feed mechanism or corresponding with the feeding port of feed mechanism.It can be sent in conveyer belt etc. Expect to be added when mechanism feeding, can also be added in material transportation process.Accelerator supply can also be set on feeding equipment Equipment, so that accelerator is added when material is located at feeding equipment.
