[0003] When spraying concrete for supporting the roadway through the robotic arm, the robotic arm can rotate flexibly. This leads to the connection point of the main shaft and the supporting wall for threading being often exposed below the spraying point, and some concrete slurry will fall on the connection point, which is rather troublesome to clean. If not cleaned thoroughly, it will erode the robotic arm and accelerate the aging of the equipment. Therefore, an automatic robotic arm for thin spraying equipment for mines is needed to solve the above problems. Summary of the Invention

[0004] The purpose of the utility model is to provide an automatic robotic arm for thin spraying equipment for mines to solve the problems raised in the above background art. When spraying concrete for supporting the roadway through the robotic arm, the robotic arm can rotate flexibly. This leads to the connection point of the main shaft and the supporting wall for threading being often exposed below the spraying point, and some concrete slurry will fall on the connection point, which is rather troublesome to clean. If not cleaned thoroughly, it will erode the robotic arm and accelerate the aging of the equipment.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is an automatic robotic arm for thin spraying equipment for mines, including:

[0007] A moving component, the moving component includes a main shaft and a first support arm, and the first support arm is rotatably connected to the middle of the upper end of the main shaft;

[0008] An anti - damage component, the anti - damage component includes a square hoop, a connecting plate, a flange and a protection plate. The square hoop is sleeved on the lower section of the first support arm through bolts and is located above the main shaft. The connecting plate is welded to the lower side of the side of the square hoop. The flange is welded to the side of the connecting plate, and the protection plate is hinged to the lower end of the square hoop.

[0009] Further, the anti - damage component further includes a rubber ring, and the rubber ring is fitted between the square hoop and the first support arm.

[0010] Further, all components of the anti - damage component are made of metal, the edges are polished into rounded corners, and the surface is treated with polytetrafluoroethylene spraying.

[0011] Further, the moving component further includes a base and a second arm. The base is fixed on an external moving vehicle, the main shaft is fixed on the base, and the second arm is rotatably connected to the top of the first arm.

[0013] Further, the adjusting component further includes a movable plate and a second rubber strip. The upper end of the movable plate is fixed at the lower end of the spring column, and the second rubber strip is fixed at the lower end of the movable plate.

[0014] Compared with the prior art, the advantages of the present utility model are as follows:

[0015] First, in the present utility model, through the provided anti-damage component, the square hoop is fixed on the lower section of the first arm by bolts, so that the two protective plates cover both sides of the main shaft. When the first arm rotates, it drives the connecting plate to rotate, and the connecting plate is always located above the main shaft. As the first arm rotates, the protective plate rotates in contact with the main shaft. The concrete slurry falling from the top of the roadway drops onto the connecting plate, the edge or the protective plate. The concrete falling on the protective plate slides onto the base. After the spraying operation is completed, the equipment is cleaned. This setting can prevent the concrete from falling at the connection between the main shaft and the first arm, which is difficult to clean, thereby accelerating the corrosion and aging of the equipment.

[0016] Second, in the present utility model, through the provided adjusting component, as the first arm rotates around the main shaft, it drives the protective plate to rotate. When the outer side of the protective plate moves to the position of the second rubber strip, it drives the movable plate at the second rubber strip to move, compressing the spring column, and the first rubber strip can scrape off the concrete attached to the side of the movable plate. This setting can lengthen the length at the edge, avoiding the exposure of the connection between the protective plate and the connecting plate due to excessive rotation of the first arm, and being unable to block the concrete.

[0033] Anti-loss component, the anti-loss component includes a square hoop 20, a connecting plate 22, a flange 23 and a protective plate 24. The square hoop 20 is sleeved on the lower section of the first arm 12 through bolts and is located above the main shaft 11. The connecting plate 22 is welded to the lower side of the square hoop 20. The flange 23 is welded to the side of the connecting plate 22. The protective plate 24 is hinged to the lower end of the square hoop 20;

[0034] The anti-loss component further includes a rubber ring 21, and the rubber ring 21 is fitted between the square hoop 20 and the first arm 12;

[0035] All the anti-loss components are made of metal, the edges are polished into rounded corners, and the surfaces are treated with polytetrafluoroethylene spraying;

[0036] The square hoop 20 plays a connecting role, the rubber ring 21 plays a connecting role and can avoid wearing the first arm 12 at the same time. The connecting plate 22, the flange 23 and the protective plate 24 play a protective role.

[0037] Working principle:

[0038] Fit the rubber ring 21 on the inner side of the square hoop 20, and fix the square hoop 20 on the lower section of the first arm 12 through bolts, so that the two protective plates 24 cover both sides of the main shaft 11. When the first arm 12 rotates, it drives the connecting plate 22 to rotate, and the connecting plate 22 is always located above the main shaft 11. As the first arm 12 rotates, the protective plate 24 rotates in contact with the main shaft 11. The concrete slurry falling from the top of the roadway drops onto the connecting plate 22, the flange 23 or the protective plate 24. The concrete falling on the protective plate 24 slides down to the base 10. After the spraying operation is completed, the equipment is cleaned.

[0039] This step can prevent the concrete from falling at the connection between the main shaft 11 and the first arm 12, which is difficult to clean, thus accelerating the corrosion and aging of the equipment.

The second rubber strip 33 can prevent the port of the movable plate 32 from wearing the protective plate 24.

[0044] Working principle:

[0045] As the first arm 12 rotates around the main shaft 11, it drives the protective plate 24 to rotate. When the outer side of the protective plate 24 moves to the position of the second rubber strip 33, it drives the movable plate 32 at the position of the second rubber strip 33 to move, compressing the spring column 30, and the first rubber strip 31 can scrape off the concrete attached to the side of the movable plate 32.

[0046] This step can lengthen the length at the edge 23, avoiding the exposure of the connection between the protective plate 24 and the connecting plate 22 due to excessive rotation of the first arm 12, and being unable to block the concrete.
