[0016] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0017] Example 1 like Figure 1 As shown, a painting robot of the present invention includes a frame 17, a walking mechanism is installed at the bottom of the frame 17, and the frame 17 is provided with a feeding mechanism 4 and a stirring mechanism 7; the discharge port of the stirring mechanism 7 is connected to a first hopper 13, the first hopper 13 is connected to a hydrocyclone 15, the hydrocyclone 15 is connected to a spray gun 10 through a spray pipe 8, the water inlet of the spray gun 10 is connected to a water pipe 9, and the spray gun 10 is mounted on the frame 17 through an adjustment mechanism.
[0018] like Figure 1 As shown, this invention discloses a spraying robot. The inlet of the mixing mechanism 7 is a dry material feeding port 3. During use, the mixed dry concrete is poured into the dry material feeding port 3. The feeding mechanism 4 is activated to spirally transport the mixed dry material to the upper part of the concrete spraying machine. After reaching the top, the mixed dry material moves laterally along the mixing mechanism and is mixed to form a wet mixture. After reaching the head position of the mixing mechanism 7, the wet material falls naturally into the first hopper 13. When wet material is needed for spraying concrete, the first hopper 13 is opened, and the material is transported through the cyclone separator 15 into the spraying pipe 8. When it reaches the spray gun 10, water is added through the water pipe 9 to form a material with suitable moisture content, which is then sprayed out by the spray gun 10 to achieve concrete spraying on the walls of underground tunnels to prevent air leakage. This spraying robot can operate efficiently in dangerous areas, ensure personnel safety, improve work efficiency, and avoid the problem of pipe blockage that easily occurs when storing wet material.
[0019] like Figure 2 As shown, the present invention provides a spraying robot (shown as A in the figure) which is deployed in the underground roadway 19, or not so close to the goaf 18. It is flexible and versatile, and can be deployed in various parts and areas underground. It can replace workers in dangerous areas and can also reduce the labor intensity of workers by spraying concrete at high and low points in conventional areas.
[0020] Example 2 like Figure 1As shown in Example 1, Example 2 of the present invention provides a spraying robot, which also includes a frame 17. A walking mechanism is installed at the bottom of the frame 17. The frame 17 is provided with a feeding mechanism 4 and a stirring mechanism 7. The discharge port of the stirring mechanism 7 is connected to a first hopper 13. The first hopper 13 is connected to a hydrocyclone 15. The hydrocyclone 15 is connected to a spray gun 10 through a spray pipe 8. The water inlet on the spray gun 10 is connected to a water pipe 9.

The walking mechanism 1 adopts a tracked movement and can be moved by remote control or manual operation by the worker. The tracked walking mechanism 1 can adapt to the uneven environment underground, has better passability than tires, and when the track fails, only part of the track needs to be replaced, making maintenance more convenient.
[0023] like Figure 1 As shown, this invention discloses a spraying robot. The inlet of the mixing mechanism 7 is a dry material feeding port 3. During use, the mixed dry concrete is poured into the dry material feeding port 3.

After reaching the top, the mixed dry material moves laterally along the mixing mechanism and is mixed to form a wet mixture. After reaching the head position of the mixing mechanism 7, the wet material falls naturally into the first hopper 13. When wet material is needed for spraying concrete, the first hopper 13 is opened, and the material is transported through the cyclone separator 15 into the spraying pipe 8. When it reaches the spray gun 10, water is added through the water pipe 9 to form a material with suitable moisture content, which is then sprayed out by the spray gun 10 to achieve concrete spraying on the walls of underground tunnels to prevent air leakage. This spraying robot can operate efficiently in dangerous areas, ensure personnel safety, improve work efficiency, and avoid the problem of pipe blockage that easily occurs when storing wet material.
[0024] like Figure 2 As shown, the present invention provides a spraying robot (shown as A in the figure) which is deployed in the underground roadway 19, or not so close to the goaf 18. It is flexible and versatile, and can be deployed in various parts and areas underground. It can replace workers in dangerous areas and can also reduce the labor intensity of workers by spraying concrete at high and low points in conventional areas.

When wet material is needed for concrete spraying, the first hopper 13 is opened, and the material is transported through the hydrocyclone 15 into the wet material spraying pipe 8. When it reaches the spray gun 10, water is added through the water pipe 9 to form a material with suitable moisture content, which is then sprayed out by the spray gun 10 to achieve concrete spraying on the underground tunnel wall to prevent air leakage. This spraying robot can operate efficiently in dangerous areas, ensure personnel safety, improve work efficiency, and avoid the problem of pipe blockage that easily occurs when storing wet material.
[0029] like Figure 1As shown, the adjustment mechanism consists of a lifting mechanism 16 and a robotic arm 12.
