Problems solved by technology

[0004] In view of the backwardness of the traditional wall plastering process and the defects of the equipment used, as well as the problems of the existing spraying equipment, the present invention provides a wall cement spraying machine, so that the spray gun can be as close as possible to the wall spraying position when working Translate, provide sufficient pressure on the spraying part, can fully penetrate into the pores on the surface of the base, increase the contact area between the slurry and the base, and effectively improve the bonding strength between the plastering layer and the base

Embodiment 1

[0027] Embodiment 1: This project is constructed on the walls, beams, and columns of the building. Before spraying, the floating slurry and dust on the wall surface should be cleaned, and water should be moistened to make preparations before spraying (the surface of the masonry wall Dust, dirt, oil stains have been cleaned, and the brick wall has been watered and moistened the day before). Medium sand for grouting, ordinary Portland cement for cement, and high-quality qualified products for interface agent, in which the ingredients of sand, cement, and interface agent are mixed according to the ratio of 0.3-0.5:1.4-1.7:1 to form a paste and placed in the slurry In the box 41, the shape of the slurry box 41 is rectangular or cylindrical. It is best to install a stirring mechanism. If there is no stirring mechanism installed, the above-mentioned mixture needs to be stirred evenly in advance to form a uniform paste. The top of the slurry box 41 is equipped with a stirring mechanis...

Embodiment 2

[0035] Embodiment 2: Another wall cement spraying machine, such as Figure 4 and Figure 5 As shown, the machine includes an outer frame 1, a lifting mechanism 2, a traverse mechanism, a spraying mechanism 4, a traction lifting mechanism 5, and the like.

[0036] Wherein the outer frame 1 is a frame with a rectangular or trapezoidal structure fixed above the base 11 . The frame includes at least a top beam 12 and a vertical slide rail 13 . The bottom or both sides of the base 11 are also equipped with road wheels 16, and the road wheels 16 can adopt electronically controlled road wheels, that is, a motor is installed on the rotating shaft of part or all of the road wheels, and the complete machine is driven to traverse by controlling the rotation of the motor. The frame also includes fixed rear frames 19 fixed on both sides of the upper rear end of the base 11, and the lower ends of the vertical slide rails 13 on both sides are respectively fixed with the upper front end of ...

Abstract

The invention discloses a wall cement mortar spraying machine. The wall cement mortar spraying machine comprises an outer frame, a lifting mechanism, a transversely-moving mechanism and a mortar spraying mechanism. The top ends of vertical screws a1 on the two sides of the outer frame are sleeved with upper rotary seats a2 correspondingly, the upper rotary seats a2 are fixed to the two ends of a top beam correspondingly, and the top ends of fixing rear frames on the two sides and the corresponding upper rotary seats a2 are fixed together. Nuts at the two ends of a cross beam of the lifting mechanism are mounted on the outer sides of the corresponding vertical screws a1 in a threaded manner. Transversely-moving rollers of the transversely-moving mechanism are supported on the upper side ofa sliding cross beam and can transversely walk, and the transversely-moving mechanism is provided with a pipe clamping mechanism. In the wall cement mortar spraying machine, mortar is directly sprayedto the surface of a structure through a pump, the problem about vertical transportation of the mortar is solved, manual mortar transportation and physical labor such as lime spoon lime delivery, supporting plate lime receiving and trowel plastering are removed, thus, the labor intensity of workers is greatly reduced, the working efficiency is improved, and a far-reaching influence is brought to building construction and management.

Description

technical field [0001] The invention belongs to the technical field of building construction equipment, and in particular relates to a cement spraying machine suitable for construction of interior and exterior walls of buildings. Background technique [0002] At present, most residential buildings in the country use the traditional mixed mortar plastering construction technology for the coarse decorative surface layer of the inner wall. Various reasons lead to quality problems such as hollowing and cracking of the plastering surface. At present, walls in the construction field are mostly filled with aerated bricks. Aerated bricks are widely used in civil high-rise buildings because of their many advantages such as energy saving, land saving, and less pollution. and industrial plants. However, the raw materials of aerated bricks are mainly cement, lime, sand and fly ash, etc., which have the characteristics of large water-cement ratio, more cementing materials, easy to abso...
