The dust collection chamber is fixedly connected to the fixed plate on both sides, and the bottom of the fixed plate is movably connected to the casters. A sealing ring is installed on the outer wall of the dust collection chamber, and the top of the dust collection chamber is fixedly connected to the support frame. This utility model, through the coordinated design of the telescopic rod, sleeve, limit block, and adjusting nut, features a simple and practical structure, easy operation, and adjustable equipment angle to accommodate walls of different heights, saving time and effort and improving work efficiency. The coordinated design of the dust suction port and fan facilitates the cleaning of dust falling during wall grinding, reducing pollution levels. It is highly practical, meets the needs of different users, and achieves optimal results.

[0003] During use, the device cannot adjust the angle of the grinding head in real time because the ceiling walls of some irregularly shaped houses are not flat and have various different tilt angles, which affects the efficiency of ceiling wall construction.

[0004] Therefore, it is necessary to invent a pre-treatment device for the construction of building roof walls to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a pre-treatment device for the construction of roof walls in buildings, in order to solve the problem that the angle of the grinding head cannot be adjusted in real time, which affects the construction efficiency of the roof walls.

[0020] Optionally, a first suction pipe is fixedly connected to the upper end of the vacuum cleaner, and two sets of second suction pipes are fixedly connected to the upper end of the first suction pipe. Each set of second suction pipes is fixedly connected to a suction head, and the two sets of suction heads are respectively fixedly connected to the front and rear surfaces of the device box.

[0021] By adopting the above technical solution, the vacuum cleaner, the first suction pipe, the second suction pipe, and the suction head work together to suck up the dust generated during the polishing process, thereby improving the cleanliness of the environment.

[0022] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0023] This invention uses a piston rod in an electric cylinder to drive a transmission rack to move up and down, which in turn drives a half gear to rotate, thereby rotating the equipment box and adjusting the angle of the grinding head.

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0032] This utility model provides, for example Figures 1 to 5 The device shown is a pre-treatment device for the construction of a building roof wall. It includes a mounting base 1, with multiple sets of casters 11 rotatably connected to the lower side of the mounting base 1. A lifting module 12 is fixedly installed on the right side of the upper surface of the mounting base 1. A grinding assembly is provided at the upper end of the lifting module 12. The grinding assembly includes an electric cylinder 2, a transmission rack 21, a positioning shell 3, a positioning groove 31, a connecting block 32, an equipment box 4, a connecting plate 41, a half gear 42, an electric motor 43, and a grinding head 44. The electric motor 43 is fixedly installed inside the equipment box 4. The grinding head 44 is fixedly connected to the upper end of the output end of the electric motor 43. The lower end of the electric cylinder 2 is fixedly installed on the upper end of the lifting rod in the lifting module 12. The transmission rack 21 and... The upper end of the piston rod in the electric cylinder 2 is fixedly connected, the lower end of the positioning shell 3 is fixedly connected to the upper end of the cylinder body in the electric cylinder 2, the positioning groove 31 is opened on the upper wall of the positioning shell 3, the transmission rack 21 is slidably connected to the positioning groove 31, the connecting block 32 is fixedly connected to the left side of the upper surface of the positioning shell 3, the half gear 42 is rotatably connected to the connecting block 32, the right side of the half gear 42 is meshed with the transmission rack 21, the connecting plate 41 is fixedly connected to the left end of the equipment box 4, the half gear 42 is fixedly connected to the right side surface of the connecting plate 41, the first support block 33 is fixedly connected to the upper surface of the positioning shell 3 near the right end, and the second support block 34 is fixedly connected to the left side surface of the positioning shell 3 near the upper end.

[0033] The lifting module 12 (which is existing technology and will not be described in detail here) is used to adjust the height of the grinding components. At the same time, the electric motor 43 drives the grinding head 44 to rotate, so that the equipment can grind the top wall at different heights. During the grinding process, the electric cylinder 2 drives the transmission rack 21 to slide up and down. The transmission rack 21 and the half gear 42 work together to drive the equipment box 4 to rotate, thereby adjusting the angle of the equipment box 4, and then adjusting the angle of the electric motor 43 and the grinding head 44, improving the adaptability of the equipment and improving the convenience of operation.

[0034] Specifically, as the piston rod in the electric cylinder 2 drives the transmission rack 21 to slide downward, the transmission rack 21 drives the half gear 42 to rotate clockwise, which in turn drives the connecting plate 41 to rotate clockwise around the connecting block 32, causing the equipment box 4 to rotate to the right until the equipment box 4 is rotated to a horizontal position. At this time, the first support block 33 supports the connecting plate 41, and the grinding head 44 is adjusted to a vertical position, which can grind the vertical wall at a high position.

[0035] Conversely, as the transmission rack 21 slides upward, it drives the half gear 42 to rotate counterclockwise, causing the equipment box 4 to rotate to the left, and then rotate the equipment box 4 to a vertical position. At this time, the second support block 34 supports the connecting plate 41, and the grinding head 44 is adjusted to a horizontal position, which can grind the horizontal top wall. When it is necessary to grind the inclined top wall, it is only necessary to adjust the height of the transmission rack 21 to adjust the rotation angle of the half gear 42, and then adjust the equipment box 4 and the grinding head 44 to any angle.

[0036] See Figure 1 A vacuum cleaner 5 is fixedly installed on the left side of the upper surface of the mounting base 1. A first suction pipe 51 is fixedly connected to the upper end of the vacuum cleaner 5. Two sets of second suction pipes 52 are fixedly connected to the upper end of the first suction pipe 51. A suction head 53 is fixedly connected to the upper end of each of the two sets of second suction pipes 52. The two sets of suction heads 53 are fixedly connected to the front and rear surfaces of the equipment box 4 respectively.

[0037] In addition, while the electric motor 43 drives the grinding head 44 to rotate and grind the top wall, the vacuum cleaner 5 is started. The vacuum cleaner 5 works in conjunction with the first suction pipe 51, the second suction pipe 52 and the suction head 53 to suck up the dust generated during grinding.

[0038] The working principle of this utility model is as follows: the piston rod in the electric cylinder 2 drives the transmission rack 21 to move up and down, which drives the half gear 42 to rotate, and then drives the equipment box 4 to rotate, thereby adjusting the angle of the grinding head 44. This effectively improves the convenience and efficiency of operation. Furthermore, the combination of gears and racks effectively maintains the stability of the grinding head 44 after angle adjustment.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
