Description

  The present invention rotates the pair of left and right traveling wheels by pushing the operation handle by hand, and rotates the main brush for sweeping and the side brush for sweeping together with the rotation, and is provided in the main body. In connection with the improvement of the hand-held floor cleaner that collects dust and other objects to be cleaned in the dust container, in detail, the objects to be cleaned including metal-based abrasives, metal-based cutting scraps and other high specific gravity particles. The present invention relates to a general-purpose hand-held floor cleaner that can be collected.

  Here, the main brush may be referred to as a horizontal axis vertical rotation brush, and the side brush may be referred to as a vertical axis horizontal rotation brush. Also, the dust container is in motion with the dust collection box or dust hopper. Further, the metal-based abrasive means a steel grid or a steel shot of a blasting device.

  Conventionally, the main brush for sweeping and the side brush for sweeping are rotated in conjunction with the rotation of the traveling wheel, respectively, and the manual push type that collects dust and other objects to be cleaned in the dust container provided in the main body ( A manually-operated floor cleaner is known (see, for example, Patent Document 1).

  As this type, there is known a type in which a motor is mounted on a main body and equipped with a fan for sucking dust (see, for example, Patent Document 2).

  In addition, there is known one capable of adjusting the brush height in order to prevent wear and deformation of the main brush (see, for example, Patent Document 3).

  In addition, there is known one that can be mounted on a forklift and can be used in a different form (for example, see Patent Document 4).

  By the way, when metal-based abrasives scattered on the steel floor such as the bottom plate of the tank typified by the oil tanks installed in the complex are used as the objects to be cleaned, it is necessary only to sweep by brush rotation of existing equipment. The cleaning recovery effect (capability) was inadequate, and it was necessary to run the same place many times.

  Under such circumstances, an apparatus configuration in which a roll-shaped permanent magnet is incorporated into a main body in order to collect magnetic particles such as iron powder is known (see, for example, Patent Document 5). However, this type of device can be used when the magnetic particles are used as a cleaning object on a floor surface such as concrete, but cannot be used on a steel floor such as a tank bottom plate. .

  The present invention is configured as described above, and according to this, the aircraft can be moved forward and backward, and the forced suction function can be augmented by linking with an external suction device (for example, an electric vacuum cleaner) including an existing dust collector. Therefore, it is possible to more efficiently clean and collect the object to be cleaned including metal-based abrasive, metal-based cutting waste and other high specific gravity powder particles.

  In addition, the object to be cleaned that has been sorted and collected can be immediately connected by externally connecting the object to be cleaned to be cleaned using gravity, wind force or magnetic force in front of the dust collector. Can be reused.

Example 1
As shown in FIG. 1 to FIG. 4, the vacuum cleaner X of the first embodiment switches and connects the transmission elements (51; 52) in the main body 1 in response to the forward / reverse rotation change of the traveling wheel 11. A joint transmission switching mechanism 5 for driving and maintaining the one-way rotation of the brush 2, and a joint having a base end connected to the dust container 7 through an opening and the other end connected to an external suction device (9) including a dust collector A nozzle 6 is provided. Here, the joint nozzle 6 may be understood as a suction conduit that can be connected to the external suction device 9 and a flexible tube. Needless to say, the dust container 7 is detachably attached to the main body 1. A handle 71 for detachment operation is provided on the top surface.

  The illustrated operation handle 4 is foldably or detachably attached. Moreover, the direction change is easy by the free caster 12 provided at the front wheel position (see FIG. 3).

  The preferred dimensional configuration is that the oil tank has an inlet / outlet of φ610 to 760 mm, so that the main body is 610 mm or less in width in consideration of cleaning in the tank, and is made compact.

  Here, the linkage transmission switching mechanism 5 has a transmission element 51 composed of a one-way clutch 511 and a gear 512, and a transmission element 52 composed of a sprocket 521 and a chain 522, and responds to a forward / reverse rotation change of the traveling wheel. The drive connection is switched. As a result, the body 1 can be moved forward and backward while maintaining the one-way rotation of the main brush 2. A specific configuration example of the transmission elements 51; 52 is shown in FIG.

  As shown in FIG. 5, the first embodiment vacuum cleaner X is a collection-only type.

  As shown in the figure, the joint nozzle 6 is connected to an external suction device 9 (specifically, a cleaning object separation device 91 described later in detail) by a flexible tube to augment the forced suction function. Here, the object to be cleaned is sucked into the external suction device 9 (91) without storing the object to be cleaned in the dust container 7. A preferred connection form to the external suction device 9 is that a dust collector 92 is arranged in the front stage of the electric vacuum cleaner 93, a cleaning object separation device 91 is interposed in the front stage of the dust collector 92, and the object to be cleaned is sucked and introduced, The steel grid is efficiently sorted and collected.

  The specific application is applied to recovery when a relatively large amount of steel grids are scattered or deposited on the floor during or after the construction by open blasting.

  Then, the object to be cleaned collected during the operation of the vacuum cleaner is promptly introduced into the object to be cleaned separator 91 without stopping in the dust container 7, where the steel grid is sorted and recovered for reuse. ing.

A possible joint nozzle 6 is provided. The linkage transmission switching mechanism 5 is not changed and has the same configuration as that of the first embodiment cleaner X (see FIG. 11).

  Here, the dust container 7 is constructed such that a stirring shaft 8 with a paddle that can be manually rotated in the cleaning width direction of the internal space is installed. The paddle-equipped stirring shaft 8 is spaced apart from at least two locations in the axial direction, and an asymmetric stirring paddle 81 is mounted between the respective installation shafts.

  The object to be cleaned collected in the dust container 7 is operated by manually rotating the stirring shaft 8 with a paddle (stirring paddle 81) through a handwheel handle 82 that extends outside the axial body, and the dust is shaken off and an external suction device ( 9) Suction and collected by [Dust collector (92) shown in detail], and a metal grinding material (steel grid described later) and high specific gravity powder particles are collected in the container 7 [selective collection].

  As shown in FIG. 6, the second embodiment vacuum cleaner Y is of the type with a stirring paddle.

  As shown in the figure, the joint nozzle 6 is connected to an external suction device 9 (specifically, the dust collector 92 shown in the drawing) by a flexible tube to augment the forced suction function.

  The specific application is applied when the steel grid is scattered on the floor surface during or after the construction by the blast device (not shown), and when the steel grid is cleaned and collected together with the dust.

  Then, at a suitable timing according to the collection amount, the object to be cleaned is selected by manually operating the stirring shaft 8 with paddle (stirring paddle 81). The dust is sucked and collected to the external suction device 9 (dust collector 92), and the steel grid is stored in the container 7. The steel grid accumulated in the dust container 7 is put into a hopper tank (not shown) of the blasting device and reused.

  The present invention is configured so that the hand-held floor cleaner can be moved forward and backward and the forced suction function can be augmented, and can be used universally by linking (connecting) with an existing external suction device. This is useful when the metal-based abrasive of the apparatus is cleaned and recovered as the object to be cleaned, and a contribution can be expected in this field.
