Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The present invention is a brush in which a gear case is provided at the front end of the operating rod, and a brush body that is rotated by the drive of the engine is provided in the gear case. This relates to vacuum cleaners.

(Prior Art and Problems to be Solved) Conventionally, in this type of brush vacuum cleaner, as shown in Fig. 6, a rotating shaft is vertically supported by a gear case provided at the front end of the operating rod. There was one in which brush bristles were implanted on the underside of a disc that was fixed to the rotating shaft and rotated in the horizontal direction. With this method, the brush bristles sweep the ground surface in a circular direction, so dust is scattered in four directions, and when this is guided by a cover and collected in one direction, the dust collection efficiency is poor, and The structure could not be simplified, and the contact area of the brush bristles was large compared to the cleaning width, resulting in a large size.

(Means and effects for solving the problem) The present invention is provided with a detachable brush body that is pivoted horizontally on both sides of the gear case and rotates under the drive of the engine. Since it rotates in the vertical direction in the front and back direction, all the brush bristles sweep dust in the same direction, making it easy to collect this dust into the dust collection container, allowing for uniform and efficient dust collection and cleaning. It is possible to reduce the contact area of the brush bristles compared to the width and reduce the load.In other words, it is possible to uniformly clean a large width with the same capacity engine, improving work efficiency. Furthermore, the brush body can be easily replaced with a snow removal vane, and it can also be used as a snow removal machine.

(Example) In FIGS. 1 to 5, reference numeral 1 denotes a cleaning section, which is connected to an engine 5 via an operating rod 3. A transmission shaft 7 for transmitting the power of the engine 5 to the cleaning section 1 is provided to penetrate inside the operating rod 3 . 11 is a grip portion fixed to the operating rod 3;
Reference numeral 3 denotes a grip provided at the end of the handle 15 fixed to the operating rod 3. The cleaning section 1 is configured as follows. That is, 17 is a gear case, and one end thereof is provided with an engaging portion 19 that detachably engages with the end of the operating rod 3. Reference numeral 21 denotes a bolt that fixes the engaging portion 19 to the operating rod 3 via a notch (not shown) which is formed by cutting out the end of the engaging portion 19 in the axial direction. 25 is a bevel gear that is pivotally supported by a bearing 27 inside the gear case 17, and 29 is an engaging body that is threadedly engaged with the boss portion 31 of the bevel gear 25, and the bearing 27 is held between the bevel gear 25 in the axial direction. The engaging body 29 is removably engaged with a square shaft portion 33 at the end of the transmission shaft 7. 35 is horizontally attached to the gear case 17, bearings 37, 3
7, and a bevel gear 39 that engages with the bevel gear 25 is fixed thereto. Reference numeral 41 denotes a brush body, which is constructed as follows. That is, reference numeral 43 is a shaft cylinder made of synthetic resin, in which metal female thread bodies 45, 45 are integrally embedded in the inner diameter portions of both ends during molding, and a threaded portion 47 at the tip of the rotating shaft 35 is inserted into the inner female thread body 45. They are screwed together to hold the inner side plate 48. 49 is a cylindrical body that is integrally fixed to the outside of the shaft cylinder 43 via radial support plates 51, 51, 51, and has three internally expanding notch grooves 53, 53, 53 are provided at positions equally dividing the circumference. 55 is notch groove 5
A brush stand is inserted and engaged in the axial direction with the brush holder 3, and the brush bristles 57 are implanted outward in the radial direction. Numeral 59 is a bolt that is screwed into the outer female threaded body 45 and fixes the outer side plate 61. Note that the female thread of the inner female threaded body 45 may be replaced with an inner diameter hole, and the threaded portion 47 may be extended and screwed into the outer female threaded body 45 and fixed with a nut. Reference numeral 63 denotes a cover fixed to the engaging part 19 by screws 65, which is formed in a shape to cover the rear, sides, and upper part of the brush body 41, and has a funnel-shaped dust collection part communicating with the rear opening 64. 65 is provided, and a dust collecting container 67 is detachably engaged with the rear end of the dust collecting section 65. 69 is a filter that covers the exhaust hole 71 of the dust collecting container 67. 7
3 is a bracket 75 fixed to the bottom surface of the cover 63
The cleaning unit 1 is supported on the ground surface by a roller that is rotatably supported by a roller and rolls on the ground surface.

In FIGS. 5 and 6, a snow removal blade 77 is attached to the groove 53 in place of the brush stand 55, and the brush body 41 becomes the snow removal blade 79. In addition, the cover 63 is replaced with a cover 83 equipped with a snow shovel 81 on the lower surface, and this cover 83 has a shape that guides the snow shoveled by the snow removal blades 41 and releases it diagonally forward and upward. It is formed.

In the above configuration, the power of the engine 5 is transmitted through the transmission shaft 7, the bevel gear 25, the bevel gear 39,
Via the rotating shaft 35, the brush bodies 41, 41 on both sides are rotated and driven in the direction of arrow A in FIG. The operator grasps the grips 11 and 13 with both hands and presses the roller 73.
When the cleaning unit 1 is pushed forward with the brush in contact with the ground, the dust on the ground is removed by the rotating brush bodies 41 on both sides.
With the air blown by the rotation of the brush body 41, the dust collection part 65 is removed from the cover 63.
The dust enters the dust collection container 67 through the filter 69, is separated by a filter 69, and is collected in the dust collection container 67. The dust inside the dust collecting container 67 is discarded without removing the dust collecting container 67 from the dust collecting section 65. In addition, during snowfall, as shown in FIGS. 5 and 6, if the cover 63 is replaced with a snow removal cover 83 and the brush stand 55 is replaced with a snow removal vane 77, the power of the engine 5 can be transmitted. Via the shaft 7, bevel gear 25, bevel gear 39, rotating shaft 35,
The snow removal blades 79, 79 on both sides are rotated and driven in the direction of arrow A in FIG. When the operator grasps the grips 11 and 13 with both hands and pushes the cleaning unit 1 forward with the snow shovel 81 in contact with the ground, the snow on the ground is scraped by the rotating snow removal blades 79 on both sides and removed from the cover. 8
3, it scatters and releases diagonally forward and upward.

[Effect of idea]

Since the present invention has the configuration as described in the claims, it sweeps the dust on the ground in the same direction, so the dust container can be installed easily and compactly, and a wide area can be cleaned uniformly. , which can be done efficiently. Further, if a dust collection container is provided as shown in claim (2), scattering of dust can be prevented. Furthermore, by installing rollers as shown in claim (3), the burden on the operator can be reduced and the cleaning work can be performed easily. Further, as shown in claim (4), if the brush stand is provided so as to be replaceable with the snow removal vane, it can be used for snow removal work during snowfall.

Note that a cloth bag may be used as the dust container. Further, the mounting position and number of the rollers are not limited to those in the embodiment, and for example, the rollers may be provided below the operating lever to also support the load of the engine.
Furthermore, the engine may be attached to a backpack frame carried by the worker, and the engine and gear case may be interlocked by a flexible transmission shaft.

FIG. 7 shows a conventional example in which a gear case 85 is fixed to the front end of the operating rod 3.
A disc 87 is provided below the disc 87 so as to be freely rotatable in the horizontal direction, and brush bristles 89 are implanted on the lower surface of the disc 87.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but can be implemented in other embodiments as well. Further, the symbols shown in the claims do not limit the technical scope of the present invention.
