Abstract

The invention discloses a mortar spraying equipment and a spray gun; the spray gun comprises a gun barrel, an air nozzle, a spray head and a nozzle, the spray head is arranged at the front end of the gun barrel, the air spray nozzle is located in the spray head and faces the front end of the spray head, and the nozzle passes through The flexible structure is connected with the spray head, and the flexible structure can lose the connection function when the pressure in the spray head reaches a predetermined value. The spray gun uses a flexible structure to connect the nozzle and the nozzle. When the mortar condenses at the nozzle, the pressure in the gun barrel will be suppressed. When the pressure reaches a predetermined value, under the pressure of the mortar, the flexible structure loses its connection, and the nozzle is disconnected from the nozzle. The connection of the nozzle; then, clean the condensed mortar on the nozzle and then install the gun barrel to continue the spraying operation. Therefore, when the spray gun is blocked by condensed mortar, the connection between the nozzle and the spray head can be disengaged, thereby preventing the spray gun from being completely blocked due to the condensation of the mortar in the entire spray gun.

Description

technical field [0001] The invention relates to mortar spraying technology, in particular to a spray gun for spraying mortar; in addition, the invention also relates to a mortar spraying equipment with the spray gun. Background technique [0002] Mortar is a slurry material that is easy to condense and segregate. In building construction, it is usually sprayed on the surface of the wall to play a protective and decorative role. [0003] At present, the mortar is usually sprayed onto the surface of the wall by spraying equipment, such as figure 1 As shown, the spraying equipment usually includes a mortar pumping device 1, a pressure gas source 2 and a spray gun 3, the front end of the spray gun 3 is provided with a nozzle 4, and the mortar pumping device 1 transports the mortar to the spray gun 3 through the first pipeline 5; The fluidity of the pressure gas source 2 is connected with the first pipeline 5 through the second pipeline 6 to provide compressed gas for the mortar...
