Embodiment Construction
[0032] The present invention will be further described below in conjunction with accompanying drawing:
[0033] Such as figure 1 , Figure 7 As shown, the flat airflow spray gun described in the present invention includes a primary rectification component and a secondary rectification component. Nozzle 3, the secondary rectification component includes three flat tubes, wherein, the second flat tube 8 is bent downward relative to the first flat tube 7, and the inner bending angle is greater than 90° and less than 180°, and the third flat tube 9 Relative to the second section of flat tube 8, it is bent upwards and connected, and the inner angle of the bending is greater than 90° and less than 180°. The outer end surface of the first section of flat tube 7 is equipped with a secondary air intake nozzle 6, and the outer end of the third section of flat tube 9 is flat. Air outlet, the primary air outlet 3 communicates with the secondary air inlet 6 through the trachea. The cross...

The invention particularly relates to a flat-shaped air flow spray gun mainly applied to the field of mortar spraying and plastering operation of building wall bodies. The flat-shaped air flow spray gun comprises a first-stage rectification member and a second-stage rectification member. The first-stage rectification member comprises a first-stage rectification cavity. A first-stage air inlet nozzle and a first-stage air outlet nozzle are installed on the first-stage rectification cavity. The second-stage rectification member comprises three sections of flat pipes; the second-section flat pipe is connected in a mode of bending downward relative to the first-section flat pipe, and the bending inner angle is larger than 90 degrees and smaller than 180 degrees; the third-section flat pipe is connected in a mode of bending upward relative to the second-section flat pipe, and the bending inner angle is larger than 90 degrees and smaller than 180 degrees; a second-stage air inlet nozzle is installed on the outer end face of the first-section flat pipe; a flat-shaped air outlet nozzle is arranged at the outer end of the third-section flat pipe; and the first-stage air outlet nozzle communicates with the second-stage air inlet nozzle through an air pipe. Because a mortar spraying machine with the novel principle conducts linear spraying, the mortar spraying speed can be increased by a large margin, and distribution of mortar on the wall surface can be smoother.
Description
technical field [0001] The invention relates to a flat airflow spray gun, which is mainly used in the field of construction wall mortar spraying and plastering. Background technique [0002] The existing technical products for spraying and plastering construction wall mortar mainly include plunger pumps, screw pumps, squeeze pumps, etc. Their common feature is that compressed air and mortar are mixed in the spray gun, and the mortar is atomized and sprayed out , the shape of the mortar after reaching the wall is point-like. It is a kind of air mortar spraying technology. [0003] There is another air-filled mortar spraying technology, which is to divide the airflow delivered by the air source into several branches, and then use these branched airflows to blow the mortar in the hopper at the same time, and the mortar will be sprayed through the mortar outlet facing the branch airflow hole. Ejection (several mortar outlets are provided if there are several branch airflows). ...
