Definitions

  • the invention relates to a device for processing of floor surfaces, in particular for grinding ground surfaces.
  • a floor sander known with wheels and a carriage-like chassis.
  • a drive motor mounted on the chassis drives a sanding belt running over two rollers to abrade a floor surface.
  • wooden floor can be sanded.
  • the invention has for its object to provide an aforementioned device, can be avoided with the problems of the prior art and in particular a comfortable for an operator editing a floor surface is possible.
  • the device has a rotating processing device for the bottom surface, wherein said at least one brush, advantageously exactly one brush, has for soil cultivation.
  • the device has a drive and a bearing for the processing device or the brush.
  • the processing device for a good handling, it is designed in the manner of a car, so it has at least one wheel, preferably at least two.
  • the processing device on the one hand, has a grinding brush for the abrading processing of the bottom surface, that is to say for grinding.
  • an application brush is provided as an alternative to the abrasive brush to advantageously apply a fluid to the bottom surface thereafter.
  • the two brushes are mounted in use on the same storage and are replaced with each other. For this they are advantageously the same size or have the same external dimensions.
  • the device according to the invention has a supply for the fluid as well as a dispensing device to apply the fluid close to the brush on the floor or directly on the brush or the order brush.
  • the term brush is to be understood here above all as functional, so above all a brush can be provided with a large number of protruding abrasive bristles, for example made of stable nylon with an abrasive coating.
  • the term brush but also an abrasive roller should be understood, which thus has a kind of rough or sandpaper-related and substantially continuous surface.
  • the application brush can be similarly varied, so either with individual bristles or as an area, which will be discussed in more detail below.
  • An abrasive brush may have a structure adapted to a grooved wooden floor, that is, solid bristles having a high-low structure.
  • an abrasive brush bristles of silicon carbide have, for example, with grain sizes in the range below 200, advantageously 60 and / or 120, depending on the type of flooring and degree of contamination.
  • a bottom surface can be machined or cleaned or abraded.
  • a fluid such as a care oil or the like. be applied to the ground ground surface.
  • the circulating application brush not only distributes the fluid on the floor surface, but also works or pushes it in, which is especially beneficial for wooden floor surfaces.
  • the device is thus either used only with the brush or only with the order brush for the purpose.
  • a replaceability of the brushes on the storage can be as simple and fast as possible, so not too much time is needed, advantageously by means of quick release.
  • the aforementioned brushes with individual bristles are particularly well suited because of the engagement in the grooves.
  • the device is particularly good for exterior surfaces with wooden planks, which can be grooved longitudinally, as they are often used for outdoor terraces, for example. So they can be cleaned, ground or sanded down and then oiled again.
  • a cleaning brush which has, for example made of nylon solid bristles. This is more likely to remove loose dirt and above all a cleaning agent can be processed with which the floor covering can be cleaned before or after sanding.
  • the cleaning agent can be applied in a manner similar to the fluid or care oil, ie with a dispensing device or even the same dispensing device as the fluid, or by hand or separately on the floor covering. Such cleaning can also be done several times between two grinding operations, as it is easier and faster.
  • the brushes can both be formed in the manner of a cylinder and extend horizontally and transversely to a machining direction of the device. They may be narrower than the device, for example, have a width which is 10% to 30% below the maximum width of the device. Although the widest possible width is advantageous for a larger, simultaneously machined floor area. At the same time, however, a necessary contact pressure is reduced.
  • a named application brush with which fluid is applied to the bottom surface can have a plurality of brush strips which are distributed at a distance from each other in the circumferential direction and which extend across the width of the application brush.
  • Such individual brush strips have the advantage that they can be replaced individually with appropriate wear and not the entire application brush needs to be replaced.
  • integral or one-piece brushes can be used, also as abrasive brushes.
  • a job brush can be formed in a further embodiment of the invention not only for applying the fluid to the bottom surface, but also for subsequent polishing. This is especially true Oiling wooden floor surfaces is an advantage. During polishing, no more fluid is applied, but merely polished by the rotating application brush the fluidized bottom surface. For this purpose, it may advantageously have bristles made of horsehair.
  • the brushes are arranged at an end region of the device, namely at a front or rear end along the machining direction. Particularly preferably, they are arranged at a front end, wherein then at the other end a hand guide device is provided. This serves to move and guide the device. It can be advantageous as a kind of push rod or the like. be educated.
  • At least one impeller may be provided at the end of the device, which comprises the aforementioned hand guide device or no brushes.
  • the aforementioned hand guide device or no brushes there are two each arranged on the outside wheels. This improves the guidance of the device and can also serve to ensure that it or a brush always has a constant distance to the bottom surface.
  • the wheels and the brush can be arranged on the device such that at least a portion of the weight rests on the processing device or brush and thus on the floor surface. So an operator does not have to exert extra contact pressure on it.
  • a weight distribution can be such that at least half the weight of the device rests on the brush.
  • a drive motor for the aforementioned drive can also be arranged in an area above the brush, so that its weight increases the contact pressure.
  • a reservoir for the fluid can be arranged in this area.
  • the dispensing device for the fluid may have dispensing openings, advantageously a plurality of distributed over the width of the applicator brush Discharge openings. These can also be designed as dispensing nozzles, when the fluid is applied with pressure. You can advantageously have a distance of a few millimeters to each other, so that over the width evenly distributed spreading is possible.
  • the discharge openings are directed to a region or a surface relatively close in front of the application brush, and seen in the machining direction. This allows a splash-free and direct application to the floor surface.
  • the discharge openings may be at least partially aligned with the application brush, so that the fluid is applied directly to the application brush and from this in turn to the floor surface. It can be provided that the fluid is applied to an upper and in the direction of rotation front region of the order brush. So this is an area that hits the ground shortly thereafter so that the fluid does not have to dwell on the application brush for too long, otherwise it could be thrown off again.
  • Such application of the fluid first to the application brush has the advantage that a fluid supply or dosage may vary slightly over time and need not be as accurate. Furthermore, this ensures that no puddles or accumulations of fluid form on the bottom surface, which have not been properly distributed or incorporated.
  • said dispensing device with the discharge openings be adjustable in their position, ie both distance to the ground and especially at an angle to it. It can also be set whether the application brush should be sprayed.
  • the applicator advantageously before the application brush on a housing or the like. be appropriate for it.
  • the dispensing device may be adjustable in its spreading width, for example to cover a complete width of a single board of a wooden floor.
  • the fluid is applied with pressure.
  • the dispensing device can be pressurized, advantageously by means of a pressure accumulator.
  • a pressure accumulator can be manually actuated or activated.
  • the pressure vessel is connected to a separate fluid container and pressurizes it.
  • it is possible that it is applied at high pressure and discharge nozzles as a fine spray, and not just dripped out when spreading.
  • a metering device for the dispensing device can be provided. It can for example have a valve that can be adjusted by hand.
  • a valve that can be adjusted by hand.
  • an adaptation of the application rate of the fluid to different conditions can be achieved, in particular if the metering device can be operated or actuated, for example, by the aforementioned hand-held device.
  • a Bowden cable or the like be provided from the metering device to a handle or a handle on the hand guide device.
  • the application rate of the fluid can be adjusted.
