[0010] Figure 1 This is a side view of the utility model;

[0011] Figure 2This is a schematic structural diagram of the rotary drive device in the present utility model;

[0012] Figure 3 This is a three-dimensional structural diagram of the rotary nozzle in this utility model.

[0013] In the above drawings, there are nozzle 1, rotary nozzle 2, discharge hole 2-1, spray slot 2-2, rotary drive device 3, drive motor 3-1, drive gear 3-2, gear ring 3-3, and protective box 4. DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0015] like Figure 1-3 As shown, the construction mortar spraying device provided by the utility model includes a nozzle 1 and a rotary nozzle 2. The nozzle 1 is connected to a mortar storage vehicle and a conveying pipe. The mortar in the mortar storage vehicle enters the rotary nozzle 2 through the pump body from the nozzle 1 and is sprayed out. The end of the nozzle 1 is rotatably installed with the rotary nozzle 2. The rotation of the rotary nozzle 2 causes the mortar entering the rotary nozzle 2 to be centrifuged, and the auxiliary mortar flows out from the discharge hole 2-1 on the side of the rotary nozzle 2. Three groups of injection slots 2-2 are provided at the end of the rotary nozzle 2. The rotary nozzle 2 is provided with three discharge holes 2-1. The ends of the injection slots 2-2 are provided at the discharge holes 2-1 of the rotary nozzle 2. The mortar sprayed from the rotary nozzle 2 is sprayed from different discharge holes 2-1 respectively. The discharge hole 2-1 is provided with injection slots 2-2 to guide the mortar and prevent it from splashing.

[0016] In the present utility model, a rotary drive device 3 is provided on the outer side of one end of the nozzle 1 close to the rotary nozzle 2, and the rotary drive device 3 drives the rotary nozzle 2 to rotate. The rotary drive device 3 includes a drive motor 3-1 and a drive gear 3-2. The drive gear 3-2 is fixedly connected to the output end of the drive motor 3-1, and the drive gear 3-2 cooperates with the gear ring 3-3 outside the rotary nozzle 2. When the drive motor 3-1 is started, the drive motor 3-1 drives the rotary nozzle 2 to rotate through the drive gear 3-2 and the gear ring 3-3.

[0017] In the present utility model, the driving gear 3-2 and the gear ring 3-3 are arranged in the protective box 4, the outer wall of the rotary nozzle 2 is rotatably installed with the middle part of the protective box 4, and the output shaft of the driving motor 3-1 penetrates into the protective box 4, and the driving gear 3-2 and the gear ring 3-3 are protected from pollution and the operator is protected through the protective box 4.
