Description

Technical Field

[0001] The present invention relates to the technical field of building construction equipment, in particular to building mortar spraying equipment for construction engineering and an operating method thereof. Background Art

[0002] Building mortar is a mortar that bonds masonry materials (bricks, stones, blocks) into a whole. It is composed of inorganic cementitious materials, fine aggregates and water, and sometimes certain admixtures. Compressive strength is often used as the most important technical performance indicator. In order to ensure the smooth completion of construction projects, many machines have replaced manual labor. After the building is built, the inner and outer walls of the entire building need to be plastered with mortar to ensure the flatness of the entire wall. In the past, wall mortar plastering was mainly carried out manually, which required a lot of labor and the plastering speed was relatively slow. In order to solve this problem, mortar spraying equipment is usually used.

[0003] Publication No. CN114941436B discloses a construction mortar spraying device for construction engineering. Through the coordinated arrangement of two stirring rings, a plurality of stirring blades and two reciprocating components, the plurality of stirring blades on the two stirring rings rotate and form a reciprocating motion in opposite directions. The plurality of stirring blades on the two stirring rings rotate and stir the mortar while driving the upper and lower mortars to continuously converge and collide toward the middle of the mixing box, breaking the stratification that occurs during the mortar mixing process, thereby making the mortar density at different positions of the stirring mechanism tend to be the same, improving the quality of the mortar, and reducing the friction between the slider and the bottom of the first annular groove through the arrangement of the ball groove and the universal ball, making the stirring ring move up and down more smoothly, thereby making the stirring operation smoother, and through the arrangement of the storage box, the mortar stirred in the mixing box can be first transported to the storage box, so that the mixing operation can be continuously carried out in the mixing box, ensuring that the spraying operation can be carried out continuously. However, the above patent still has the following problems during actual use:

[0004] Although the construction mortar spraying equipment used in the construction project can fully mix the mortar raw materials, it cannot clean the wall surface that needs to be sprayed before spraying the mortar, and workers are required to clean it in advance, which not only increases the burden on the workers, but also increases the cost of spraying. After spraying, the excess mortar dripping from the wall cannot be recovered, resulting in the phenomenon of mortar dripping and waste, which is not conducive to saving the cost of spraying.

[0005] Therefore, a construction mortar spraying device and an operating method thereof are proposed to solve the above-mentioned problems. Summary of the Invention

[0049] Working principle: Before using this kind of construction mortar spraying equipment and its operation method, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 11As shown, first, the second support spring 202 and the second level 203 are used to perform a secondary inspection of the spraying and conveying vehicle 201 and the flatness of the wall surface, and at the same time, the raw materials used for spraying are put into the mixing box 207, and the first mixing motor 208 is started to drive the mixing turbine 209 to rotate, and the spiral force is generated by the mixing turbine 209 to perform preliminary mixing of the raw materials, and at the same time, the second mixing motor 211 is started to drive the mixing auger 212 and the mixing bracket 213 to rotate, and the raw materials are stirred for the second time by the vertical mixing rod 215 and the mixing auger 212 to further improve the mixing effect of the mortar raw materials, and the inner wall of the mixing box 207 can be cleaned by the vertical cleaning scraper 214 and the spiral cleaning scraper 216 to avoid the phenomenon of residual waste of raw materials, and the delivery pump 217 can be used to achieve The raw materials are transported to the mortar nozzle 232 through the delivery pipe 218, so that the mortar is sprayed. By starting the lifting motor 220 to drive the lifting rotating rod 221 to rotate, under the action of the second bevel gear transmission assembly 222, the lifting threaded rod 223 is rotated, and at the same time, the lifting threaded sleeve 224 drives the translation bracket 225 to move up and down, which can realize the height adjustment of the mortar nozzle 232. At the same time, the translation motor 226 is started to drive the third sprocket transmission assembly 227 and the translation threaded rod 228 to rotate, so that the translation threaded sleeve 229 drives the nozzle bracket 230 to move longitudinally, which can realize the longitudinal adjustment of the mortar nozzle 232. At the same time, the adjustment motor 231 is started to drive the mortar nozzle 232 to rotate, which can adjust the vertical angle of the mortar nozzle 232, so as to facilitate all-round spraying of the wall.

[0050] Secondly, the mortar recovery box 103 inside the horizontal bracket 101 is used to collect the fallen mortar, and at the same time, the mobile motor 105 is started to drive the first sprocket transmission assembly 106 and the horizontal threaded rod 107 to rotate, so that the horizontal threaded sleeve 108 drives the first rotating bracket 109 and the support frame 110 to move horizontally, and at the same time, the horizontal threaded rod 107 drives the first bevel gear transmission assembly 111 and the vertical threaded rod 112 to rotate, so that the vertical threaded sleeve 113 drives the second rotating bracket 137 and the support frame 110 to move vertically.
