Description

Technical Field

[0001] The utility model belongs to the technical field of leveling devices, in particular to an outdoor roof drainage slope grinding device. Background Art

[0002] Outdoor foot (drainage) water dispersion is to protect the wall foundation from rain erosion. The ground around the exterior wall is often made into an outward slope to drain the rainwater from the roof to a distant place. This is called water dispersion, which is one of the effective measures to protect the foundation of the house. Since the drainage slope is usually constructed and poured with materials such as cement and concrete, a smoothing device is needed to smooth the cement surface.

[0003] The existing patent application number CN201720940711.6 discloses a trowel device for construction, including a trowel plate, a motor, a switch, a battery and a handle, wherein the four sides of the trowel plate are each provided with an upwardly tilted flange, the flange is arranged in an arc structure, the four flanges are connected end to end, and the four flanges are arranged in a rectangular ring structure, a support rod is vertically fixedly installed in the middle of the surface of the trowel plate, the handle is arranged above the trowel plate, the motor is fixedly installed at the lower end of the handle, the shaft of the motor is arranged vertically downward, a cover body covering the motor is arranged outside the motor, the upper end of the cover body is fixedly connected to the handle, the lower end of the cover body is provided with a through hole, the upper end of the support rod extends into the cover body along the through hole, and is fixedly connected to the shaft on the motor. The utility model has a simple structure and is easy to use. The trowel plate can be effectively rotated while pushing the plastering knife, the contact area with the concrete is increased, and the concrete can be smoothed more quickly, which greatly increases the work efficiency and reduces the work intensity.

[0004] However, in the above scheme, since the leveling device generates a lot of dust particles during the rotating grinding process, these particles are splashed everywhere under the drive of the high-speed rotating grinding disc, and then spread throughout the entire outdoor environment, causing a sharp decline in air quality. Therefore, we propose an outdoor house foot drainage slope leveling device. Utility Model Content

[0020] In this embodiment, Figure 2As shown, the dust collecting structure includes a first fixing ring 10 and a collecting bag 11; the first fixing ring 10 is sleeved on the dust suction pipe 7 located in the dust suction box 5, and the first fixing ring 10 is fixed on the side wall of the dust suction box 5; a groove 10.1 is arranged on the first fixing ring 10 along the annular direction; a clamping groove 10.2 is symmetrically arranged on the first fixing ring 10; the opening of the collecting bag 11 is adapted to the dust suction pipe 7; a second fixing ring 11.1 is arranged at the opening of the collecting bag 11; a protrusion 11.2 is arranged on the outer side of the second fixing ring 11.1 corresponding to the groove 10.1, and a clamping block 11.3 is arranged on the second fixing ring 11.1 corresponding to the clamping groove 10.2; the clamping block 11.3 can be made of rubber; the second fixing ring 11.1 is sleeved on the dust suction pipe 7, and the collecting bag 11 is fixed by the cooperation between the second fixing ring 11.1 and the first fixing ring 10. When in use, the second fixing ring 11.1 is set on the collection bag, and the collection bag has only one opening, which is the second fixing ring 11.1; the collection bag is fixed on the dust suction pipe through the connection between the card slots and the card blocks on the first fixing ring and the second fixing ring, and is used to collect waste produced during grinding. This embodiment is mainly set in a smaller dust suction box so that the collection bag can fill the entire collection box, which is convenient for collecting more dust.

[0021] In this embodiment, Figure 3 As shown, the fan 6 is arranged on the top surface of the dust box 5; the dust collection structure includes a filter 8 and a collection box 9; the filter 8 is detachably arranged below the fan 6 and on the top surface of the dust box 5; the collection box 9 is arranged below the filter 8. The collection box is located below the dust suction pipe on the dust box, and a clamp ring is arranged on the dust box corresponding to the collection box, and the collection box is fixed in the clamp ring. The dust particles in the collection box are transported through the box door to avoid excessive dust particles from spreading throughout the outdoor environment, thereby improving the air quality.

[0022] In this embodiment, when a large-scale bottom surface needs to be polished, the fan can be set on the ground, and the dust suction pipe of the fan is connected to the dust suction box of the polishing device to improve the dust suction efficiency of the polishing device. For the dust suction box set on the ground, there is space to set the filter net and the collection bag at the same time; the collection bag is set in the dust suction box on the base, and the filter net can be set on the fan on the ground for further collection. When the collection bag and the filter net are set at the same time, the mesh of the filter net is smaller than the mesh of the collection bag.

[0023] In this embodiment, the base is a shell structure, the opening of the shell is arranged toward the ground, the shell is in an inverted U shape, and the edge of the grinding disc is adapted to the edge of the inner wall of the shell.

[0024] An inverted U-shaped block 12 is disposed on the base 1 . The inverted U-shaped block 12 is disposed above the motor 4 . The handle 2 is disposed on the top surface of the U-shaped block 12 .

[0026] The handle 2 is provided with a switch for controlling the fan 6 .

[0027] During use, after starting the motor, the motor drives the grinding disc to rotate, and the switch of the control fan is turned on before the grinding disc is placed against the drainage slope that needs to be smoothed; as the grinding disc smoothes the uneven position of the drainage slope, the area around the grinding disc is vacuumed through the vacuum tube. Since the bottom end of the grinding disc is provided with an arc slope, and the bottom end of the vacuum tube is provided with an oblique mouth, the dust particles generated by grinding will escape along the arc slope after smoothing. At this time, the vacuum tube is convenient for collecting dust particles, and the dust particles are drawn into the dust box through the fan for collection, thereby avoiding excessive dust particles from spreading throughout the outdoor environment and improving air quality.
