Mortar spraying machine and mortar spray gun thereof

Abstract

The invention discloses a mortar spraying machine and a mortar spray gun thereof. The mortar spray gun comprises a spray nozzle, a spray gun barrel and a compressed air tube. The spray nozzle is arranged at one end of the spray gun barrel, an air outlet of the compressed air tube is positioned inside the spray gun barrel, and the distance from the air outlet of the compressed air tube to an outlet of the spray nozzle is adjustable. The mortar spraying machine and the mortar spray gun have the advantages that the distance from the air outlet of the compressed air tube to the outlet of the spray gun is adjustable, so that the quantity of mortar between the air outlet of the compressed air tube and the outlet of the spray nozzle can be changed; the distance from the air outlet of the compressed air tube to the outlet of the spray nozzle can be adjusted according to different characteristics (such as a water-retention rate and the consistency) of the mortar, so that the mortar can be sufficiently mixed with high-pressure air ejected out of the compressed air tube under different conditions, an atomization effect of the spray nozzle can be improved, the ejected mortar is uniform, and later-stage levelling workload can be reduced.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a mortar spray gun and a mortar spray machine equipped with the mortar spray gun. Background technique [0002] In the previous building construction, plastering was usually done manually, which not only has low labor efficiency and high labor intensity, but also causes defects such as hollowing on the surface of the building due to manual plastering. In order to overcome the above shortcomings, construction sites now usually use Mortar spraying machine is used for mechanical spraying construction of mortar. [0003] The mortar spraying machine is a machine that disperses the mortar into a mist and sprays it on the surface of the object to be coated. Its working principle is: after the mortar is poured into the hopper, it is evenly stirred by the stirring device, and finally sent to the mortar spray gun by the pumping mechanism. squirt. Wherein, the mortar spray gun include...
