Description

Technical Field

[0001] The utility model mainly relates to the technical field of construction engineering, in particular to a construction mortar spraying device for construction engineering. Background Art

[0002] Construction mortar spraying equipment is a kind of equipment widely used in construction projects. It is used to spray mortar materials on walls, floors and other surfaces to provide protection and decorative effects.

[0003] Traditional construction mortar spraying equipment is generally equipped with moving wheels at the bottom, so that the nozzle can move horizontally to spray mortar. However, the angle and spacing between the nozzle and the bottom of the equipment cannot be adjusted. When the horizontal height of the spraying position needs to be adjusted, the entire equipment needs to be manually tilted to adjust the nozzle. The spraying process is time-consuming and labor-intensive. In addition, when spraying the ceiling, the distance between the nozzle and the ceiling is far, so in order to ensure the spraying is in place, the high-pressure pump power will be large, and the equipment power consumption will be high.

A limiting post is provided on the inner side wall of the second vertical plate, and the limiting post is located on the rotation path of the limiting protrusion. The rotation paths of the fixed tube and the telescopic tube do not contact the limiting posts on both sides, and the limiting protrusions are tightly pressed against the limiting posts to limit the rotation path of the rotating roller.

[0008] Preferably, a connecting plate is provided on the top of the mortar barrel, a stirring motor is fixed on the connecting plate, the output end of the stirring motor is connected to a stirring vertical shaft, the stirring vertical shaft is inserted into the interior of the mortar barrel, a number of stirring horizontal shafts are equidistantly arranged on the stirring vertical shaft along the axial direction, a sealing ring is provided at the connection between the stirring vertical shaft and the mortar barrel, the sealing ring is used to seal the connection between the mortar barrel and the stirring vertical shaft, and the stirring horizontal shaft is used to evenly stir the interior of the mortar barrel, so that leakage is not easy to occur during the stirring process.
