Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of shotcrete spraying machines, and in particular relates to mortar spraying equipment. Background Art
[0002] Mortar spraying machine, also known as spraying machine, is a mechanical equipment used for spraying concrete or other materials. It is widely used in protective projects such as tunnels, culverts, subways, bridges, coal mines, high marsh mines, hydropower projects, underground projects, and construction projects. Its main function is to prevent sand and soil from falling from the inner wall of the tunnel, prevent landslides, prevent collapse, and spray or repair refractory materials in various industrial furnaces. The spraying machine uses compressed air to continuously transport concrete through the material cavity along the feed pipeline and spray it onto the construction surface to form a dense concrete support layer. According to different construction processes, concrete spraying machines can be divided into three types: dry, wet, and semi-wet. Common types include dry concrete spraying machines and wet concrete spraying machines. Among them, dry spraying machines are one of the commonly used construction equipment. Traditional dry spraying machines usually rely on manual feeding, which is inefficient. In addition, because the material feed port has a certain height, feeding is time-consuming and labor-intensive, and it is easy to generate a lot of dust, which has a serious impact on the construction environment and workers' health. Therefore, the utility model provides a mortar spraying device, which is convenient for loading and has a dust-proof function, which is of great significance for improving loading efficiency, saving workers' physical strength, and reducing environmental pollution.

A mixing tank is installed inside the frame 1 for mixing and stirring the mortar. In addition, on one side of the mixing tank, a spiral pump 4 is installed on the frame 1 for extracting and conveying mortar. On the other side of the mixing tank, a vertical screw conveyor 5 is installed to realize the vertical conveying of the mortar. The inlet of the spiral pump 4 is closely connected to the discharge port of the mixing tank to ensure the smooth flow of the mortar. The outlet of the spiral pump 4 is connected to the feeding hose 3, and the end of the feeding hose 3 is connected to the spray gun 6 to spray the mortar to the designated position. A first feed port 7 is set on one side of the bottom of the barrel of the vertical screw conveyor 5, and the first feed port 7 is rotatably connected to the material dispensing barrel 8 inside, and a driving motor is installed at one end of the material dispensing barrel 8 to ensure its normal rotation. A material shovel 9 is evenly fixed on the barrel of the material-dispensing barrel 8 to achieve uniform dispensing of the mortar. Finally, a discharge pipe 10 is connected to one side of the barrel top of the vertical screw conveyor 5 to ensure that the mortar can be discharged smoothly.
[0019] In order to facilitate the entry of materials, in this embodiment, as a preferred technical solution of the utility model, the bottom wall of the barrel of the vertical screw conveyor 5 located at the first feed port 7 is a sloped structure.
