Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a spraying machine for coating large areas of building exterior walls. Background Art

[0002] During the construction process, in order to improve the protection and aesthetics of the wall, a layer of spray material will be sprayed on the exterior wall. The exterior wall spray material is used to paint the exterior walls of the building, so the most important indicator is resistance to ultraviolet radiation, which requires that it does not change color after long-term exposure. At the same time, in order to improve the spraying efficiency of the exterior wall spray material, a sprayer will be used to assist in the spraying of the spray material to improve the spraying efficiency of the spray material on the outside of the wall.

[0003] Usually when the sprayer is used, a suction device is installed on one side of the pump body, and the suction device is installed on the feed pipe. By starting the pump body, the pump body generates a negative pressure state, and then the spray material is sucked out from the inside of the spray barrel, and the sucked paint is sprayed on the wall using the nozzle. At the same time, in order to improve the suction efficiency of the spray material inside the spray barrel, the absorption device is set at the bottom end of the spray barrel, and then the absorption device is used to absorb the spray material. However, due to the viscosity of the spray material, this will cause the spray material to adhere to the inner wall of the spray barrel, resulting in the absorption device absorbing the spray material in the spray barrel, and unable to absorb the paint adhering to the inner wall of the spray barrel, resulting in clogging of the spray material and reduced utilization rate. For this reason, we propose a sprayer for large-area painting of building exterior walls. Utility Model Content

[0004] In response to the shortcomings of existing sprayers for large-area painting on building exterior walls, the utility model provides a sprayer for large-area painting on building exterior walls, which has a protective cover arranged inside the spray barrel. At the same time, a first rotating blade is installed inside the spray barrel. The first rotating blade drives the spiral blade to rotate, that is, the spray material can be transported to the middle of the spray barrel, thereby improving the spray material absorption efficiency and solving the problems raised in the above-mentioned background technology.

[0005] The utility model provides the following technical solutions: a sprayer for large-area coating of building exterior walls, comprising a pump body, a first material delivery pipe and a second material delivery pipe are installed on the outside of the pump body, the end of the first material delivery pipe is installed with a protective sleeve, the inner sleeve of the lower end of the protective sleeve is sleeved with a connecting seat, the outer part of the connecting seat is fixedly connected with a spiral blade, the upper part of the connecting seat is fixedly connected with a first rotating blade, the spiral blade is placed inside a spray barrel, the end of the second material delivery pipe is fixedly connected with a spray material placement chamber, one end of the spray material placement chamber is fixedly connected with a limiting sleeve, and the inner sleeve of one end of the limiting sleeve is movably sleeved with a sealing cover.

[0006] Preferably, grooves are formed on the outside of the protective sleeve at equal intervals, and the protective sleeve is arranged at the bottom end of the spray barrel.

[0007] Preferably, the first rotating blade extends to the inside of the first feeding pipe, the inside of the spiral blade fits onto the outside of the protective sleeve, and the outside of the spiral blade fits onto the inner wall of the spray barrel, while the lower end of the spray barrel is tapered.

[0008] Preferably, the interior of the spray placement chamber is fixedly connected with a first diverter plate and a second diverter plate, the first diverter plate is arranged outside one end of the second material delivery pipe, and the second diverter plate is triangular and located at one end of the limit sleeve.

[0009] Preferably, the sealing cover is circular, and a discharge hole is provided between the spray placement chamber and the connection between the limiting sleeve.

[0010] Preferably, a nozzle is fixedly connected to the outside of the sealing cover, and an atomizer is installed inside the nozzle.

[0011] Preferably, a rotating rod is fixedly connected to the middle part of one side of the sealing cover, and a second rotating blade is fixedly connected to one end of the rotating rod. The rotating rod passes through the first diverter plate and the second diverter plate, and the second rotating blade is arranged inside the second feed pipe, and a controller is installed inside the second feed pipe.

[0012] Compared with the existing spraying machines for large-area coating of building exterior walls, this utility model has the following beneficial effects:

[0013] 1. The sprayer for large-area coating of the exterior wall of the building is arranged inside the spray barrel through a protective sleeve. During the process of the protective sleeve extracting the spray material inside the spray barrel, the extracted spray material drives the first rotating blade to rotate, and the first rotating blade drives the spiral blade to rotate. During the spiral rotation of the spiral blade, the spray material inside the spray barrel can be automatically transported to the bottom end to avoid the spray material not contacting the protective sleeve, resulting in the inability to extract the spray material, and then resulting in untimely delivery of the spray material, affecting the spraying efficiency. At the same time, during the rotation of the spiral blade, impurities adhering to the outside of the protective sleeve can be scraped off to reduce the blockage of impurities on the outside of the protective sleeve, which affects the extraction efficiency of the protective sleeve for the spray material.

[0014] 2. The sprayer for large-area coating of the building's exterior wall transports the spray material through the spray material placement chamber to the inside of the limit sleeve. At the same time, the spray material contacts the second rotating blade, which can drive the sealing cover to rotate. At the same time, the sealing cover drives the nozzle to rotate, and the nozzle can drive the spray material to spray on the wall. At the same time, when the spray material rotates to spray the wall, the uniformity of the spray material spraying is improved and the accumulation of the spray material during spraying is reduced.

[0024] See also Figure 5 The outside of the protective sleeve 4 is provided with grooves at equal intervals, and the protective sleeve 4 is arranged at the bottom end of the spray barrel 8. The protective sleeve 4 is provided with grooves on the outside, and the protective sleeve 4 is arranged inside the spray barrel 8. After the spray material is filled into the inside of the spray barrel 8, the spray material contacts the protective sleeve 4 at the same time, and the holes opened on the outside of the protective sleeve 4 absorb the spray material. The pump body 1 is used to extract the spray material, which can drive the spray material to be sprayed onto the wall.

[0025] See also Figure 5 The first rotating blade 6 extends to the inside of the first feeding pipe 2, the inside of the spiral blade 7 is fitted to the outside of the protective sleeve 4, and the outside of the spiral blade 7 is fitted to the inner wall of the spray barrel 8. At the same time, the lower end of the spray barrel 8 is tapered. During the extraction process of the spray material driven by the first feeding pipe 2, the spray material contacts the first rotating blade 6, that is, the spray material drives the first rotating blade 6 to rotate, and drives the spiral blade 7 to rotate through the linkage relationship. During the rotation of the spiral blade 7, the spray material inside the spray barrel 8 can be concentratedly transported to the bottom end. At the same time, during the rotation of the spiral blade 7, the spray material adhering to the surface of the protective sleeve 4 is scraped off to prevent the spray material from adhering to the inside of the holes opened on the outside of the protective sleeve 4, causing the protective sleeve 4 to be blocked and affecting the transmission of the spray material.

[0026] See also Figure 3The interior of the spray material placement chamber 9 is fixedly connected with a first diverter plate 11 and a second diverter plate 12. The first diverter plate 11 is arranged on the outside of one end of the second material delivery pipe 3. At the same time, the second diverter plate 12 is triangular, and the second diverter plate 12 is located at one end of the limit sleeve 10. The first diverter plate 11 and the second diverter plate 12 are fixedly connected through the interior of the spray material placement chamber 9. The first diverter plate 11 is arranged at one end of the second material delivery pipe 3. During the process of the second material delivery pipe 3 conveying the spray material to the interior of the spray material placement chamber 9, the first diverter plate 11 can push the spray material into the interior of the spray material placement chamber 9. At the same time, after the diversion of the second diverter plate 12, the spray material can be accurately pushed to the interior of the limit sleeve 10, thereby improving the uniformity of the spray material during spraying.

[0027] See also Figure 3 The sealing cover 13 is circular, and a discharge hole is provided between the connection between the spray material placement chamber 9 and the limiting sleeve 10. The sealing cover 13 is circular, and a discharge hole is provided between the connection between the spray material placement chamber 9 and the limiting sleeve 10, that is, the spray material filled in the spray material placement chamber 9 can be discharged through the discharge hole.

[0028] See also Figure 3 The outside of the sealing cover 13 is fixedly connected to a nozzle 14, and an atomizer is installed inside the nozzle 14. The atomizer belongs to the existing technology. Through the unique shape of the atomizer, the material of the material is dispersed and processed to form an atomized state. The atomizer belongs to the existing technology, so it is not elaborated on. The nozzle 14 is fixedly connected to one end of the sealing cover 13. When the spray material is sprayed from the inside of the sealing cover 13 under high pressure, the spray material passes through the nozzle 14. At the same time, an atomizer is installed inside the nozzle 14, that is, the spray material passing through the nozzle 14 can be atomized. At the same time, the spray material can be sprayed onto the wall in an atomized manner after passing through the nozzle 14, avoiding the phenomenon of accumulation when the spray material is sprayed, thereby improving the spraying efficiency of the wall.

[0029] See also Figure 3 , the middle part of one side of the sealing cover 13 is fixedly connected with a rotating rod 15, and one end of the rotating rod 15 is fixedly connected with a second rotating blade 16, the rotating rod 15 passes through the first diverter plate 11 and the second diverter plate 12, and the second rotating blade 16 is arranged inside the second material delivery pipe 3, and a controller is installed inside the second material delivery pipe 3. The controller plays a role in opening the internal valve of the second material delivery pipe 3, which is convenient for driving the spray material to be sprayed out, and the controller belongs to the prior art, so it is not elaborated on. The second rotating blade 16 is arranged inside the second material delivery pipe 3. When the spray material is extruded, the spray material drives the second rotating blade 16 to rotate, and the rotating rod 15 drives the sealing cover 13 to rotate synchronously. That is, when the spray material is sprayed out, the sealing cover 13 drives the nozzle 14 to rotate. At this time, when the spray material is sprayed onto the wall, a rotating spraying state can be formed, which improves the spraying efficiency, can be sprayed on a large range, and avoids the phenomenon of spray material accumulation during spraying.

[0030] Working principle: When in use, the spray material is placed inside the spray barrel 8, and at the same time, the first delivery pipe 2 drives the protective sleeve 4 to be placed inside the spray barrel 8, and a positioning device can be set on the outside of the first delivery pipe 2 to ensure that the protective sleeve 4 is suspended inside the spray barrel 8. At the same time, the position of the second delivery pipe 3 is adjusted, and the second delivery pipe 3 is facing the wall. By starting the pump body 1, the pump body 1 generates a high-pressure state, which can suck out the spray material inside the spray barrel 8, that is, the spray material is absorbed into the inside of the first delivery pipe 2 through the protective sleeve 4, and is transported to the inside of the spray material placement chamber 9 through the second delivery pipe 3, and in the spray barrel 8 During the partial spray material absorption process, the spiral blade 7 rotates, and the spiral blade 7 can scrape the spray material on the outside of the protective sleeve 4 to reduce the accumulation of the spray material. At the same time, during the rotation of the spiral blade 7, the spray material can be automatically driven to be transported to the bottom end of the spray barrel 8. At the same time, the spray material is transported to between the limit sleeve 10 and the sealing cover 13 through the spray material placement chamber 9. At the same time, the second rotating blade 16 assists in driving the sealing cover 13 to rotate. During the rotation of the sealing cover 13, the spray material can be driven to be sprayed evenly through the nozzle 14, and an atomizing device is installed inside the nozzle 14. The atomizing device and the sealing cover 13 are in a rotating state, which improves the spraying efficiency of the spray material.
