[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a dust collector that automatically sweeps and collects dust scattered on the ground while pushing and driving.

[0002]

[Prior Art]

 As a conventional dust collector by manual pushing operation, the rear wheels on the left and right sides are supported by relatively large diameter rear wheels, and a small-sized wheel is installed on the front portion of the box structure dust collector. A rotating brush that rotates when the handle is pushed is provided inside the dust collector, and dust on the floor is swept and collected into the dust collector by the action of the rotating brush through the opening provided in the bottom wall of the dust collector. Things are known.

Further, a brush which rotates inward by the rotation of the rear wheels is provided on one side of the front end portion of the dust collector as described above, and the dust in the corner portion is guided toward the dust collector by this brush, It is known that dust is collected by the action of a rotating brush.

[0004]

[Problems to be solved by the device]

 The dust collector as described above is mainly used for cleaning homes and buildings, and is not suitable for dust collection outside the building. Also, cleaning the corners with a brush provided on one side of the front part of the dust collector is effective only on one side, and therefore the operation of the dust collector is complicated.

The object of the present invention is to enable the dust collectors that rotate inward to each other to clean a wide range by the one-way pushing and running action of the dust collectors, and to move the dust collectors in the left and right directions by centrifugal force. The widening of the brush material makes it easier and more efficient to clean the corners on the arbitrary side.

[0006]

[Means for Solving the Problems] The structure of the present invention which solves the problems of the prior art has a structure in which the lower part is in contact with the entire lower surface of the outer peripheral part of the circular seat plate on the left and right of the front part of the frame body with the rear wheels. A long brush material is laid vertically, and two dust collectors that rotate inwardly are arranged side by side, and the front wheels are respectively placed in the hollow portions of the dust collectors surrounded by the brush material. The front wheel axle and the dust collector rotary shaft are connected by a rotation transmission means for converting horizontal rotation into vertical rotation, and the rear of the pair of left and right dust collectors is further connected. A dust container is detachably mounted on the frame body.

[0007]

[Action]

 The horizontal rotation of the axle of the front wheel that rotates due to the pushing operation converts the rotation axis of the dust collecting body into the vertical rotation by the rotation transmitting means, and the two dust collecting bodies move as the frame advances. Each is turned inward, and dust on the floor or road is moved to the center and sent to the back, and collected in the dust container. Further, the long brush material is expanded outward due to the centrifugal force to further expand the sweep range and effectively clean the corners.

【Example】

 Next, details of the embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view, FIG. 2 is a vertical sectional side view of the same as above, FIG. 3 is a partially cutaway front view, FIG. 4 is a plan view, and FIG. 5 is a partially cutaway front view of an essential part of another embodiment.

Reference numeral 1 denotes a frame body, and at the rear portion of the frame body 1, both lower end portions of a pusher 2 having an inverted U-shaped front are fixed. A rear wheel 3 having a relatively small diameter is pivotally supported at the center of the rear portion of the frame body 1. Horizontally long shaft pedestals 5 are provided on the left and right of the front part of the frame 4 connected to the front part of the frame body 1, and the bottom wall 5a constituting the shaft pedestal 5 is as shown in FIG. In addition, it is inclined downward toward the front.

On the left and right sides of the bottom wall 5 a of the shaft pedestal 5, there are mounted rotating shafts 8 in a substantially vertical posture, the upper ends of which are supported by bearing metal 6, bearing 7, etc., respectively. A circular seat plate 9 having a comparatively large diameter is fixedly penetrated through. A relatively long brush material 10 whose lower end contacts the floor is replaceably provided on the entire lower surface of the outer peripheral edge of both circular seat plates 9, and the brush material 10 and the circular seat plate 9 are provided. And form a dust collector A having a hollow portion 10a surrounded by the brush material 10. Since the upper surface of the circular seat plate 9 is parallel to the surface of the bottom wall 5a of the shaft pedestal 5, the front end portion of the circular seat plate 9 is inclined downward and attached thereto. As shown in FIG. 2, the brush material 10 has a front portion strongly pressed against the floor surface and a rear portion slightly lifted from the floor surface to improve the dust collection efficiency.

A spiral gear 12 a is fixed to the lower end of the rotary shaft 8 with a bolt 11. On the other hand, as shown in FIG. 3, a wheel arm 13 having a frontal shape of an angle is symmetrically and rotatably provided in the middle of the rotary shaft 8 so that both wheel arms 13 can be rotated vertically. Both ends of the horizontally oriented axle shaft 14 are rotatably supported between the side portions. Then, the two front wheels 15 housed in the hollow portion 10a are fixed to the axle 14 with the key structure so as to sandwich the rotating shaft 8, and at the center of the axle 14, The spiral gear 12b that meshes with the spiral gear 12a is fixed. Therefore, the horizontal rotation of the axle shaft 14 is converted into the vertical rotation through the spiral gears 12b and 12a so that the rotary shaft 8 rotates vertically, and both the dust collecting bodies A are directed in the directions of the arrows in FIG. It is designed to be rotated.

As is clear from FIGS. 3 and 4, the left and right dust collectors A are attached to the shaft pedestal 5 of the frame 4 so that they are close to each other. The dust is properly pinched and swept by.

As shown in FIG. 4, a cover 16 having a curved surface with a radius centered on the axis of the rotating shaft 8 is detachably attached to the upper portion of the frame 4, as shown in FIG. is there. Further, large notches 17 are formed on the left and right side walls of the cover 16 corresponding to the dust collecting body A, and the brush material 10 forming the dust collecting body A is centrifuged as shown by the phantom line in FIG. It is designed to be able to effectively clean the corners of the floor surface and the object perpendicular to it by pushing it out to the outside greatly by exertion.

A large number of exhaust holes 18 are formed on both side wall surfaces of the frame body 1 behind the both dust collecting bodies A, and a dust collecting container 19 having a box structure having an opened front surface is detachably mounted. .. 20 is a handle in the figure.

As shown in FIGS. 1 and 2, the frame 1 is provided with a guide plate 21 which is inclined downward toward the front, and the front end edge of this guide plate 21 has a hollow portion 10 a of the dust collector A. The brush material 10, which is inserted into the rear part and rotates, slides on the upper surface of the guide plate 21 and guides dust onto the guide plate 21 to efficiently collect the dust in the dust container 19. It was made possible.

In the above-described embodiment, the axle 14 is mounted between the left and right wheel arms 13 that are rotatable with respect to the rotary shaft 8, and the front wheels 15 are provided on the axle 14. Although the dust collector is steered by swinging the front wheel 15, the rear wheel 3 can be swung so that the entire steering can be performed, and the wheel arm 13 of the front wheel 15 is pivoted. An embodiment in which the number is fixed to 5 will be described with reference to FIG.

As shown in FIG. 5, the collar 22 fixed to the upper portion of the wheel arm 13 is fixed to the shaft pedestal 5 with bolts 23. On the other hand, the large diameter gear 24 is fixed to the upper part of the rotary shaft 8 whose upper end is rotatably supported by the shaft pedestal 5 by a key structure. A receiving seat 25 is fixed to the shaft pedestal 5, and a gear 26 axially supported by the receiving seat 25 is meshed with the large diameter gear 24. Outside the collar 22 fixed to the wheel arm 13, the large diameter gear 27 fixed to the circular seat plate 9 constituting the dust collecting body A and having the same diameter as the large diameter gear 24 is rotatable. The large-diameter gear 27 is engaged with the gear 26 while being fitted. The same components as those of the embodiment shown in FIGS. 1 to 4 are designated by the same reference numerals and detailed description thereof will be omitted.

The horizontal rotation of the axle 14 is converted into vertical rotation via the spiral gears 12b and 12a, and the rotation shaft 8 rotates vertically. The rotation of the rotary shaft 8 is transmitted to the large diameter gear 27 via the large diameter gear 24 and the gear 26, and the dust collector A rotates. Since the embodiment shown in FIG. 5 does not perform steering, the number of front wheels 15 may be one or two.

In the above-described embodiment, the pusher is moved by being pushed manually, and the dust collector is rotated by the driving operation of the front wheels to clean and collect the dust. For example, by using a motorbike tow, it is possible to operate using power.

According to the configuration of the present invention as described above, the following effects can be obtained. (A) Since the front wheel provided on the frame is built into the hollow part surrounded by the brush material that constitutes the dust collector, the circular seat plate that constitutes the dust collector can be reasonably enlarged in diameter. The rotation peripheral speed of the brush material can be increased, and the dust collection efficiency of dust can be improved. (B) Further, since the front wheel is not axially supported on the outer side of the frame body but is disposed in the hollow portion surrounded by the brush material of the dust collecting body, it protrudes to the outer side of the frame body on the brush material. Since it is possible to give a sweeping action, the cleaning width can be made wider than the machine body width, and it is possible to clean the corners of the floor surface and the object standing upright against it, and also dust collection. Since two bodies are arranged on the left and right, cleaning of the corners on both the left and right sides can be done only by one-way running of the machine without changing the operation direction of the dust collector. Easy operation improves the cleaning efficiency. Can be achieved. (C) Since the two dust collectors each rotate inward, it is not only possible to clean a wide range, but the sandwiching sweeping force of both dust collectors is doubled to collect dust even with some heavy objects. Can be recovered. (D) When the wheel goes up and down along the unevenness of the floor surface, the dust collectors on the left and right also go up and down along the wheel and are always in contact with the floor surface, so that uniform cleaning can be achieved. (E) There are few transmission parts, there is no need to transmit the side and upper parts of the machine by belts or chains as in the conventional case, the structure is simple, and the machine can be downsized. (F) By using two dust collectors in front, dust is collected and pinched and conveyed at the same time, so that dust can be reliably collected without scattering even in the presence of wind.
