Description

Technical Field

[0001] The utility model relates to the technical field of spraying machines, in particular to a concrete spraying machine. Background Art

[0002] Traditional spraying machines are too complicated in function and structure, and can only be equipped with one spraying port, which makes the construction efficiency low and cannot meet the actual needs. In order to solve this problem, a new type of concrete spraying machine is provided in the prior art, specifically the CN219785208U model. This spraying machine is provided with two parallel cylinders, and a set of air intake pipes and nozzles are respectively configured on each cylinder. Concrete is sprayed out from the two nozzles at the same time by compressed air, thereby significantly improving the work efficiency.

For example, there is a problem of excessive dust during construction, especially when working in the open air, which will cause serious pollution to the environment. In addition, due to its complex structure, it is not equipped with a protective structure. If hard objects accidentally fall onto the device, it is easy to cause damage to it. Utility Model Content

[0021] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0022] like Figure 1-Figure 7 The concrete spraying machine of the utility model shown in the figure comprises a crawler chassis 6 and a spraying device installed on the crawler chassis 6, and is characterized in that: a transverse plate 1 is arranged directly above the spraying device, and a connecting plate 9 is arranged on the crawler chassis 6, which is fixed to the lower end surface of the transverse plate 1 and surrounds the spraying device. The vertical distance between the transverse plate 1 and the crawler chassis 6 forms a placement space for the spraying device, and a connecting hole 12 is opened on the connecting plate 9 to fit the outer side wall of the spraying device nozzle, and a dust removal device is arranged on the crawler chassis 6 and is connected to the inside of the placement space for the spraying device.

[0023] By providing a threaded countersunk hole 11 on the upper end surface of the connecting plate 9, and providing a threaded through hole 8 matched with the threaded countersunk hole 11 on the cross plate 1, the cross plate 1 and the connecting plate 9 are fixedly connected by the threaded rod 7 fastened in the threaded through hole 8 and the threaded countersunk hole 11, and the threaded rod 7 is rotated to make the threaded rod 7 screwed out of the threaded through hole 8 and the threaded countersunk hole 11, so that the cross plate 1 can be removed from the connecting plate 9, which is convenient for the staff to repair the device when it is damaged or fails. By providing a connecting groove 10 matched with the upper end of the connecting plate 9 on the cross plate 1, the connecting groove 10 can be used to facilitate the staff to place the cross plate 1 on the connecting plate 9 and fix it. By providing a U-shaped lifting ring 13 on the side wall of the cross plate 1 away from the spraying device, the U-shaped lifting ring 13 can be used to facilitate the staff to use a crane to remove and install the cross plate 1 on the connecting plate 9. The dust removal device includes an exhaust fan 3 connected to a dust removal water tank 5 and the interior of the spraying device placement space, and the output end of the exhaust fan 3 is connected to the dust removal water tank 5 through a pipe 4. The exhaust fan 3 can absorb the dust generated by the spraying device when the spraying device is working in the spraying device placement space, and transfer it to the dust removal water tank 5 through the pipe 4. The air intake pipe in the spraying device is connected to the air compressor through the air supply pipeline, and the feed port of the spraying device is connected to the concrete delivery pipeline through a joint to the concrete delivery station on the well. The connecting plate 9 is provided with holes that are compatible with the concrete delivery pipeline and the air supply pipeline. The holes can be used to connect the spraying device with external equipment for construction without dissipating dust to the outside.

[0024] Combined with Figure 1-7 It can be seen that the method of using the utility model is as follows: first, it is necessary to drive the crawler chassis 6 to transfer the spraying device and the dust removal device to the preset position, and then connect the injection pipe with the nozzle 2 of the spraying device, and then start the spraying device to carry out construction work. The spraying device will produce dust during the construction process. At this time, turn on the exhaust fan 3 to absorb the dust in the space where the spraying device is placed, and transfer it to the dust removal water tank 5 through the pipeline 4.
