[0022] Example 1
[0023] This embodiment describes a building mortar spraying device for construction projects, such as... Figure 1 As shown, it includes a spray gun 1. The spray gun 1 is existing technology. Existing spraying equipment usually consists of a housing, pipes and a spray gun. This application does not improve the original working method and structure of the spray gun, but only adds it to the outside of the gun body. Therefore, the spray gun 1 can be an existing spray gun that controls mortar spraying by pressing a trigger.
[0024] The spray gun 1 is equipped with a trowel 3, and a linkage component is provided between the trowel 3 and the trigger of the spray gun 1, so that the spraying and troweling functions can be realized through one device, reducing the steps of tool replacement and making it more convenient to use. At the same time, it can be switched to the troweling state immediately after spraying to smooth the mortar on the wall in time, which can effectively prevent the mortar from hardening and solidifying in the wall and pipes for too long.
[0025] When the trigger of the spray gun 1 is pressed down to spray mortar, the trowel 3 swings outward synchronously to be outside the discharge port area of the spray gun 1. This makes it easier to smooth the sprayed mortar with the trowel 3. When the trigger is pressed down to spray the remaining wall, the trowel 3 swings outward synchronously through the linkage component to avoid the trowel 3 blocking the mortar from being sprayed onto the wall.

[0042] The push plate two is connected with the outer side wall of the spraying gun 1 through a fixed block two to rotate upward and downward, a baffle for blocking the push plate two is vertically fixed at the right end of the adjusting plate two, the left end of the push plate two is attached to the baffle, the right end of the push plate two is connected with the trigger of the spraying gun 1 through a connecting belt two, and a fixed plate two is fixed on the left side of the outer side wall of the spraying gun 1, a tension spring is arranged between the fixed plate two and the adjusting plate two, the two smearing plates 3 are closely attached in the natural state, so as to connect the trigger of the spraying gun 1 and the smearing plates 3 to run synchronously, thereby realizing smooth switching between the two modes of spraying and smearing without affecting each other through simple operation;
[0043] A nut is sleeved on the fixed rod two for fixing the fixed rod two, so as to fix the fixed rod 6 in the smearing mode, thereby avoiding the shaking of the smearing plates 3 during smearing of the mortar by the smearing plates 3 to affect the smearing effect.
[0044] The locking assembly is arranged between the two trowels 3 for fixing the trowels 3, so as to further increase the adhesion between the two trowels 3 in the troweling mode, and avoid that the gap between the two trowels 3 is too large to affect the troweling effect when the trowels 3 are used to trowel the mortar.
[0045] The locking assembly is a buckle, which is arranged on the front and back sides of the trowel 3, so as to fix and connect the two trowels 3 when the trowels 3 are adhered, and avoid that the two trowels 3 have too large movement range to affect the troweling effect when the trowels 3 are used to trowel the mortar.
[0046] The buckle is a prior art, which is usually composed of a positioning member and a fastener. In use, the positioning member is fixed on one of the trowels 3, and then the fastener is fixed on the other trowel 3, so that the positioning member and the fastener are connected when the two trowels 3 are adhered.

During the rotation process of the second push plate, the left end of the second push plate pushes the second adjusting plate to the right. During the right movement of the second adjusting plate, the third connecting belt pulls the trowel 3 to the right side and stretches the tension spring on the left side of the trowel 3, so as to drive the two trowels 3 to swing up and down respectively to expose the discharge port of the spraying gun 1 and enter the spraying mode. After spraying is completed, release the trigger of the spraying gun 1. During the resetting process of the trigger, the pulling force of the second connecting belt on the second push plate disappears, so that the right pushing force of the second push plate on the second adjusting plate disappears.
