The utility model provides a plastering gun, the structure is as shown in figure 1, including mortar section of thick bamboo 1 and push away thick liquid pole 2. The mortar barrel 1 is provided with a cavity for containing mortar, one end of the mortar barrel is provided with a plastering nozzle 13, and the other end of the mortar barrel is opened. The slurry pushing rod 2 is inserted into the cavity along the opening part, and the front end of the slurry pushing rod 2 is provided with a piston 22 which is in interference fit with the inner side wall of the mortar barrel 1. The plastering nozzle 13 is provided with a mortar outlet communicated with the inner cavity of the mortar barrel 1, as shown in fig. 1, the plastering nozzle 13 is of a duckbill structure and extends to the front of the mortar barrel 1, and the foremost end of the plastering nozzle 13 is rectangular. The cross section of the pulp outlet hole is strip-shaped, the front end of the pulp outlet hole is also rectangular, and the width of the front end of the pulp outlet hole is smaller than the length of the pulp outlet hole. The mortar is extruded from the mortar outlet hole by the extrusion of the mortar pushing rod 2, and the plastering gun is moved at the same time, so that the mortar is extruded in a belt shape. Constructors move the plastering guns according to needs to paint the banded mortar on the surface of the building, thereby improving the construction efficiency.

Optionally, the mortar barrel 1 is cylindrical, in order to enable mortar in the mortar outlet hole to uniformly flow out, a tapered connector 12 is arranged at the front end of the mortar barrel 1, the diameter of the connector 12 is gradually reduced from back to front, the plastering nozzle 13 is connected with the front part of the connector 12, the length of the connection part of the connector 12 and the plastering nozzle 13 is not less than 1/2 of the length of the plastering nozzle 13, and meanwhile, the central line of the plastering nozzle 13 coincides with the axis of the connector 12. As shown in fig. 2, the plastering nozzle 13 is of a duckbill structure, which is gradually thinned from the connecting point with the connector 12 to the edge, and correspondingly, the width of the grout outlet is gradually reduced from the connector 12 to the edge of the plastering nozzle 13 until a rectangular outlet is formed at the front end of the grout outlet.

In addition, in order to reduce the mass of the plastering gun, the mortar barrel 1 and the mortar pushing rod 2 can be made of aluminum alloy materials. The piston 22 may be embodied as a rubber piston, which is connected to the rod 21 by means of bonding or bolting.

In this embodiment, the plastering gun is composed of a mortar barrel 1 and a mortar pushing rod 2, a plastering nozzle 13 is arranged at the front end of the mortar barrel 1, and the plastering nozzle 13 is provided with a mortar outlet communicated with the inner cavity of the mortar barrel 1. The mortar can be extruded out of the mortar outlet hole by pushing the mortar pushing rod 2. Simultaneously, the mortar barrel 1 is connected with the plastering nozzle 13 through the conical connector 12, the width of the mortar outlet hole is gradually increased along the direction towards the connector 12, when mortar enters the mortar outlet hole, the pressure in each direction is approximately equal, and the mortar outlet of the plastering gun is ensured to be even.

Optionally, as shown in fig. 3, the mortar pushing rod 2 includes a rod body 21, one end of which is coaxially connected to a piston 22, and the other end of which is provided with a handle 23, wherein the piston 22 is in interference fit with the inner side wall of the mortar barrel 1. The handle 23 is shown in fig. 3 as a circular plate, but it may be configured in a rod shape or other shapes as desired by the user.

Optionally, in order to guarantee the intensity of pushing rod 2, the periphery of the rod body 21 is provided with a reinforcing rib 24, specifically, reinforcing rib 24 extends radially outward along the rod body 21, and both ends of reinforcing rib 24 are connected with piston 22 and handle 23 respectively, and when pushing rod 2 along the axial, reinforcing rib 24 can disperse the axial force and the shearing force that the rod body 21 bore. The number of the reinforcing ribs 24 is usually two or more and is uniformly distributed along the circumferential direction of the rod body 21.

Further, in order to reduce the dead zone in the mortar barrel 1 and improve the utilization rate of mortar, the front end of the piston 22 is tapered and has the same taper as that of the connector 12. When the slurry pushing rod 2 is pushed in the axial direction, the front end of the piston 22 can extend into the connector 12, and the slurry in the connector 12 is pushed out.

When the mortar is coated, the mortar needs to be coated on a construction part on one hand, and the surface of the mortar needs to be coated and leveled on the other hand. For conveniently floating the mortar surface, the plastering gun also comprises a bending part, the bending part is a barrel body 11 with a rectangular cross section and is connected with the front end of a plastering nozzle 13, and the axis of the bending part is a preset angle with the axis of the mortar barrel 1.
