[0063] In this embodiment, an impeller 72 is installed at the feeding port.

[0064] This invention provides a construction method for a natural stone powder spraying device, comprising the following steps:

[0065] S1. Divide the wall surface to be sprayed into multiple construction sections.

[0066] S2. Move the movable base 1 to the first construction section and lock the movable base 1 with the locking element 11.

[0067] S3. Add the natural stone powder coating into the storage bin a of the mixing tank 2.

[0068] S4. The second drive structure 42 drives the screw 36 to adjust the height of the base box 4, and the third drive structure 51 adjusts the flip angle of the platform 5 so that the nozzle 6 is aligned with the first construction section at a preset angle and preset height.

[0069] S5. Start the delivery pump. At the same time, the first drive structure 21 drives the mixing tank 2 to move back and forth along the length of the wall, so that the nozzle 6 moves in an S-shape and sprays the natural stone powder coating evenly onto the first construction section.

[0070] S6. Move the movable base 1 to the next construction section and repeat steps S4 to S5.

[0071] The natural stone powder spraying device of the present invention can provide rolling support for the device through rollers, which can move the device to a suitable position, and then the support rod can be rotated to push the support plate at the bottom of the support rod against the ground to lock the position of the device.

[0072] The first motor of the natural stone powder spraying device of the present invention can drive the transmission shaft to rotate, thereby driving the drive wheel to rotate, so as to adjust the position of the mixing box in the length direction of the movable base, and adjust the spray head to the corresponding position according to the spraying position on the construction section of the wall.

[0073] The natural stone powder spraying device of this invention has a fourth motor installed on the feeding box. The fourth motor can drive the conveying auger to rotate. The conveying auger can drive the feeding impeller to rotate through the first sprocket, the second sprocket and the chain, which can pour natural stone powder into the inside of the feeding port, and the feeding impeller can send the natural stone powder into the feeding box through the feeding port. Then, the auger blades push the interior of the natural stone powder feeding box to move, and can send the natural stone powder into the storage silo through the feeding port. Water is then added to the storage silo, and the natural stone powder and water are stirred evenly by the agitator to form a natural stone powder coating.

[0074] The natural stone powder spraying device of the present invention is equipped with an electric hydraulic push rod that drives two movable seats to move towards each other or away from each other. Since the middle parts of the two hinged arms are pivotally connected together, and the two ends of the hinged arms are respectively hinged to the movable seats and the sliding sleeve, the movable seats can drive the two hinged arms to rotate. The hinged arms push the sliding sleeve to move along the axial direction of the guide rod and apply the thrust to the slide, which can move the slide in the assembly chamber along the second horizontal direction, thereby adjusting the position of the spray head in the width direction of the movable base.

[0075] The second motor in the natural stone powder spraying device of the present invention can drive the driven gear through the active gear, thereby driving the screw to rotate. The screw can push the threaded sleeve, the base box and the spray head to move synchronously in the vertical direction. The spray head can be pushed to the corresponding height according to the spraying part of the wall.

[0076] The natural stone powder spraying device of the present invention is provided with a third drive structure. The third drive structure includes a tilting gear, a rack, and an electro-hydraulic push rod. The support is rotatably mounted on the base box via a rotating shaft. The rotating shaft is coaxially connected to the tilting gear. The rack is positioned between the base box and the tilting gear. The rack is vertically oriented. The tilting gear meshes with the rack. The fixed end of the electro-hydraulic push rod is fixed to the base box, and the telescopic end of the electro-hydraulic push rod is connected to the rack, which can push the rack to move. The rack pushes the tilting gear, thereby causing the spray head to tilt up and down, changing the rotation angle of the spray head and adjusting it to a suitable position so that the natural stone powder coating sprayed from the spray head can be precisely applied to the wall surface.

[0077] The natural stone powder spraying device of the present invention optimizes the stone powder finishing tool, reduces the number of smears and joints in the construction surface coating, and adjusts the spraying distance and spraying height through the first drive structure, the second drive structure and the third drive structure, so that the spraying uniformity can be controlled, and the final surface appearance is smooth and flat.

[0078] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
