Definitions

  • the invention relates to a device for extracting grinding dust on rotary grinders, in particular drywall grinders.
  • suction device for grinders with a rotating abrasive which is at least partially surrounded by a suction hood, known in which the suction hood has a peripheral edge with a fixed support edge and a resilient element, the flexible movement of the suction hood substantially parallel to the axis of rotation of the rotating abrasive relative to the grinder permits.
  • the DE202005011659 describes a grinding device, which is a head part, a handle which is pivotally mounted on the head part, at least one rotatably mounted on the head part grinding plate and a drive unit for a hood which covers the at least one sanding pad and surrounds it with its edge, and one on the Hood has provided connection device for a vacuum cleaner.
  • a sliding ring is attached at the edge of the hood replaceable.
  • the at least one sanding pad and the sliding ring are so relative to each other adjustable so that the front edge of the sliding ring and the front of the grinding disc are aligned.
  • a vacuum can be generated by the vacuum cleaner under the hood, which is sufficient to hold the headboard to the wall.
  • the vacuum required for this can certainly be generated by a commercial vacuum cleaner, because since the hood covers the grinding wheel, it has a considerable size, which is co-determining in addition to the achievable negative pressure for the achievable holding force.
  • a disadvantage of all known technical solution is that the housing on the wall or the ceiling, that is sucked on the sanding ground and thus handling is difficult.
  • the object of the invention is to further develop a device for extracting grinding dust on rotary grinders so that the most complete possible extraction of sanding dust and sanding material can be ensured immediately after their formation with a vacuum cleaner, without it sucking the grinder on the ground.
  • this device is based on the illustration 1 and the embodiment will be explained in more detail.
  • the inventive device for extracting grinding dust on rotary grinders consists of a arranged on a suction pipe 6 drive group and a movable grinding head.
  • the drive group and the movable grinding head enclosing a suction hood 1 is arranged, which faces one of the surface to be machined and having around the entire circumference of the suction hood guided sealing profile 2.
  • the suction tube 6 which serves as a carrier element and guide rod for the drive group and movable grinding head, the material to be sanded is transported by the grinding head in the direction of the suction device.
  • a commercial vacuum cleaner is used as a suction device.
  • the volume flow generated by the suction device and guided through the suction pipe 6 can be adjusted by means of a secondary air regulator 5.
  • This secondary air regulator 5 is arranged in the suction pipe 6 and designed so that by means of selbigen secondary air regulator 5, an opening in the suction pipe 6 can be opened or closed.
  • the suction hood 1 of the grinding head is equipped with the sealing profile 2, which rests on the surface to be machined.
  • the sealing profile 2 is designed such that a Schleifgutaustritt in the region of the grinding head is prevented during working, but at the same time good sliding of the grinding head is achieved on the surface to be ground.
  • the suction hood 1 is provided with auxiliary air holes 7.
  • These secondary air holes 7 are preferably arranged continuously from the top of the exhaust hood 1 into the interior of the exhaust hood 1. It has proved to be advantageous if these secondary air holes 7 are distributed as uniform circular ring on the exhaust hood 1.
  • the operator only needs to spend a fraction of the contact force for the grinding process, as the suction head also pulls the grinding head to the surface.
