Compared with the traditional manual coating method, this mortar spraying equipment has higher efficiency and can ensure a more uniform construction effect. However, there are some defects and deficiencies that need to be improved: (1) Some existing mortar spraying equipment is an integrated structure, and the relevant parts are difficult to disassemble at will, and different mortar types cannot be quickly replaced. Moreover, when the mixing structure has been working for a long time, it is difficult to remove and clean it separately; (2) When using some existing mortar spraying equipment, construction workers need to hold the nozzle to spray, which is inconvenient and labor-intensive. After a long time, it will cause arm pain. Although some spraying equipment can fix the nozzle on the equipment for spraying, the height of the nozzle is fixed and difficult to adjust at will; (3) Due to the structural design of some existing mortar spraying equipment, the coverage range of the mortar is small during spraying, and it can often only be concentrated at one point, making the thickness of the mortar spray layer not uniform, which leads to more manual work for finishing in the later stage. Therefore, in order to solve the above problems, the utility model provides a building mortar spraying device for construction engineering, which is of great significance. Utility Model Content

[0032] The stirring mechanism includes a motor 16, which is mounted on the top cover 12, and a stirring shaft 17 is mounted on the output end thereof. The shaft body of the stirring shaft 17 is fixedly connected to a plurality of stirring blades 18. Mortar is placed in the barrel 10, and the stirring shaft 17 and the stirring blades 18 are driven by the driving motor 16 to rotate together. When the stirring blades 18 rotate, the mortar can be mixed evenly according to a certain ratio so that the mortar maintains an appropriate consistency and ensures that it can pass through the spraying device smoothly.

[0033] The spraying mechanism includes a nozzle 19 and a high-pressure pump 20. The interior of the nozzle 19 is a hollow structure, with a feed port 21 on one side and several nozzles 22 on the other side of the nozzle 19. The high-pressure pump 20 is installed on the base 1, and a suction pipe 23 and a guide pipe 24 are respectively installed on the high-pressure pump 20. The other ends of the suction pipe 23 and the guide pipe 24 are respectively connected to the discharge port 13 and the feed port 21. By driving the high-pressure pump 20, the evenly stirred mortar can be introduced into the nozzle 19 along the suction pipe 23 and the guide pipe 24, and sprayed out through each nozzle 22 under the action of high pressure, so that the mortar can be sprayed onto the wall or other building surfaces.

[0034] Among them, the positioning port 6 is circular, and a buffer ring 25 is provided on its inner wall surface. The buffer ring 25 is made of elastic materials such as sponge and is fixed by glue or other means. When the barrel 10 is installed in the positioning port 6, the buffer ring 25 can play a buffering protection role to prevent the barrel 10 from directly contacting the inner wall of the positioning port 6 and causing collision and wear.

[0035] Among them, the positioning seat 8 is distributed in an equidistant ring shape along the circumferential direction of the positioning port 6. The number of positioning blocks 11 is the same as that of the positioning seat 8. The width thereof is equal to the width of the positioning groove 9, and the center of each positioning block 11 corresponds one-to-one to the center of each positioning groove 9. When the barrel 10 passes through the positioning port 6, each positioning block 11 can be aligned and fitted into the corresponding positioning groove 9. At this time, the mutual cooperation between the positioning block 11 and the positioning groove 9 can play a positioning role so that the barrel 10 can be fixed on the support plate 5. Different types of mortar (such as thermal insulation mortar, waterproof mortar, etc.) can be placed in the barrel 10. The barrel 10 can be taken out from the positioning port 6 by lifting it upward, so as to quickly replace different types of mortar.

[0036] Among them, the top edge of the barrel 10 protrudes outward, and a number of studs 26 are fixedly connected to its top. The studs 26 are equidistantly distributed in a ring along the top edge of the barrel 10, and nuts 27 that match them are threaded on the studs 26. A number of mounting holes 28 are provided on the surface of the top cover 12. The mounting holes 28 are the same in number and diameter as the studs 26, and the center of each mounting hole 28 corresponds one-to-one to the center of each stud 26. When the top cover 12 is covered on the barrel 10, each stud 26 can be aligned with and pass through the corresponding mounting holes 28. At this time, the nuts 27 are threaded onto each stud 26 and tightened. The top cover 12 together with the stirring mechanism can be fixedly installed on the barrel 10 through the mutual cooperation between the studs 26, the mounting holes 28, and the nuts 27. By unscrewing the nuts 27, the top cover 12 together with the stirring mechanism can be removed so that the stirring mechanism can be cleaned separately.

[0037] Among them, the support plate 15 is L-shaped, the width of its inner wall is equal to the width of the nozzle 19, and the support plate 15 is equidistantly linearly distributed along the height direction of the bracket 14. The nozzle 19 can be attached to the inner wall of the support plate 15. The nozzle 19 can be supported and fixed by the support plate 15, so that the spraying operation can be performed without holding it, and the height of the nozzle 19 can be adjusted as needed by placing the nozzle 19 on support plates 15 at different heights.

[0038] Among them, the top surface of each support plate 15 is provided with a layer of anti-slip pad 29, and the surface of the anti-slip pad 29 is engraved with a herringbone anti-slip pattern. The anti-slip pad 29 is made of elastic material such as rubber and is fixed by glue or other means. When the nozzle 19 is placed on the support plate 15, the anti-slip pattern on the surface of the anti-slip pad 29 can increase the friction between the nozzle 19 and the support plate 15 to play an anti-slip role, thereby preventing the nozzle 19 from slipping and displacement during the mortar spraying process.

[0039] Among them, the nozzle 22 is connected to the inner cavity of the nozzle 19 and is equidistantly linearly distributed along the length direction of the nozzle 19. The multiple nozzles 22 can effectively expand the spraying range of the mortar to prevent the mortar from being concentrated at one point after spraying, thereby ensuring the uniform thickness of the mortar spray layer, and effectively avoiding the need for more manual trimming in the later stage. A sealing plug 30 is installed on the nozzle 22. The end diameter of the sealing plug 30 is equal to the inner diameter of the nozzle 22, and the end surface of the sealing plug 30 and the inner wall surface of the nozzle 22 are respectively engraved with mutually matching external threads and internal threads. When it is necessary to adjust the spraying range of the mortar, the sealing plug 30 can be threaded into the corresponding nozzle 22. At this time, the nozzle 22 can be sealed by the sealing plug 30 to prevent the mortar in the corresponding nozzle 22 from spraying out, so that the spraying amount of the mortar can be adjusted according to the size of the construction area to reduce unnecessary material waste.

[0040] The circuits, electronic components and chip modules involved in the present invention are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present invention does not involve improvements to software and methods.

[0041] The standard parts used in the application documents can all be purchased on the market. All components in this application document can be customized according to the description in the specification and drawings.

The machinery, parts and equipment all adopt conventional models in the existing technology. The electrical components appearing in this article are all connected to the external main controller and 220V AC power, and the main controller can be a conventional known device that controls the LED lamp body, etc.

[0042] The working principle of this utility model is:

[0043] When the present invention is in use, the handle 4 can be held and the push handle 3 can be pushed so that the roller 2 can be used to move the spraying device to the designated position. When the designated position is reached, the motor 16 can be driven to drive the stirring shaft 17 to rotate together with the stirring blades 18, so that the mortar in the barrel 10 can be mixed evenly according to a certain ratio through the stirring blades 18, so that the mortar maintains an appropriate consistency. Then the high-pressure pump 20 can be driven to guide the evenly stirred mortar along the suction pipe 23 and the guide pipe 24 into the nozzle 19, and sprayed out through the nozzles 22 under the action of high pressure, so that the mortar can be sprayed onto the wall or other building surfaces. When spraying, the nozzle 19 can be attached to the inner wall of the support plate 15. At this time, the nozzle 19 can be supported and fixed by the support plate 15, so that there is no The spraying operation can be performed by hand-holding, and the height of the nozzle 19 can be adjusted as needed by placing the nozzle 19 on a support plate 15 at different heights. A plurality of nozzles 22 are provided on the nozzle 19. The plurality of nozzles 22 can effectively expand the spraying range of the mortar to prevent the mortar from being concentrated at one point after spraying, thereby ensuring that the thickness of the mortar spray layer is uniform, effectively avoiding the need for more manpower for trimming in the later stage. When the type of mortar needs to be changed, the barrel 10 can be lifted upward to be removed from the positioning port 6 to quickly change to different mortar types (such as thermal insulation mortar, waterproof mortar, etc.). After the spraying device has been used for a long time, the top cover 12 can be removed together with the stirring mechanism by unscrewing the nut 27 so that the stirring mechanism can be cleaned separately.
