Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a movable road surface cleaning machine which can be easily moved and can remove or collect dust, earth and sand, etc. while moving efficiently.

[0002]

2. Description of the Related Art Many cleaning vehicles have been developed and proposed for removing dust, dirt, snow, etc. accumulated on the road, but their mechanisms are often large.
Also, dust and dirt cannot be used for snow removal,
The one for snow removal cannot be used for dust and earth and sand. Further, for example, most of the dust and earth and sand are those which are removed by using a roll type brush (for example, Japanese Utility Model Laid-Open No. 56-16621,
Actual Kaihei 1-69826).

However, since these types use a roll-type brush, they scatter dust and earth and sand in the circumferential tangential direction, so that dust and earth and sand are scattered outward. As a result, many are equipped with a suction device for absorbing and collecting dust and earth and sand. Even if it is equipped with a suction device, the dust collection / exclusion efficiency is poor and it scatters outward. In addition, even if dust and dirt are moved on the road surface with a brush, there is a limit to the movement distance on the road surface with the brush, and in the end it can be handled by repeatedly moving the cleaning vehicle back and forth on the road surface. Was there. Further, the conventional ones are mainly for removing dust and earth and sand, and are not for collecting, in other words, sweeping.

[0004]

The present invention has been invented from the above background and achieves the following objects.

An object of the present invention is to provide a general-purpose moving road surface cleaning machine which sweeps an object with a simple mechanism and is suitable for dust, earth and sand, and snow.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a view showing the outer appearance of the mobile cleaning device of the present invention. FIG. 2 is a plan view in which a part of FIG. 1 is cut. The main body 1 is made by welding a main body made of U-shaped steel or the like and welding a steel plate on the frame or fixing it by bolts, and has a substantially rectangular parallelepiped shape.

One end of a handle frame 2 made of two pipes is fixed to the rear end of the main body 1. The other ends of the handle frames 2 and 2 are bent, and the grips 3 and 3 are
Are formed. Tires 4 and 4 are provided at the rear end of the main body 1. The tires 4 and 4 can be moved forward, backward, and stopped by a drive mechanism described later. The tires 4 and 4 are provided with a clutch mechanism (not shown), and the clutch mechanism is connected to clutch levers 5 and 5 provided near the grip 3 by wires (not shown). When the clutch lever 5 is operated, the power transmission to the tire 4 is cut off and the tire 4 does not move forward or backward. Therefore, the moving road surface cleaning device is turned left or right. A tire (not shown) having a smaller diameter is provided in front of the lower surface of the main body 1. This tire only supports the main body 1 and is not rotationally driven.

An engine 10 is mounted on the main body 1. The output shaft of the engine 10 is directly connected to the transmission box 11 via a clutch (not shown). A transmission gear mechanism is incorporated in the transmission box 11. The speed change gear mechanism is connected to a change lever 12 provided on the handle frame 2 via a wire. Therefore, by operating the change lever 12, it is possible to control the change of the moving speed of the tire 4 and the stop thereof.

At the tip of the output shaft 13 of the transmission box 11, a universal joint 14, that is, a universal joint 14 is provided. The universal joint 14 is further provided with a universal joint 14 via a shaft. Further, the transmission shaft 15 at the tip of the universal joint 14 is rotatably supported by a support body 17 made of a rectangular plate material via a bearing 16. A sprocket 18 is provided at the tip of the transmission shaft 15, and a chain 19 is engaged with the sprocket 18.

On the other hand, at both ends of the support 17, the mounting shaft 2
0 and 20 are rotatably supported. Both mounting shafts 20,
A sprocket 21 is attached to 20. Further, on the mounting shafts 20 and 20, projections 23 are provided at constant angle positions on the outer circumferences of the pulleys 22 and 22. An endless belt brush 25 is bridged between the pulleys 22 and 22. The endless belt brush 25 has holes 26 formed at one end in the width direction at regular intervals.

A projection 23 meshes with the hole 26.
After all, the rotation output of the engine 10 is the clutch, the transmission gear box 11, the output shaft 13, the universal joints 14, 1.
4, the transmission shaft 15, the sprocket 18, the chain 19, the sprocket 21, the mounting shaft 20, and the pulleys 22 and 22 are transmitted to rotate the endless belt brush 25.

Frames 30 are integrally provided on both sides of the main body 1. The frame 30 is a frame integrated with the main body 1, and is a pipe having a square cross section. The support 17 is
It is connected to the main body 1 via the frame 30 and the adjusting rods 31, 31. Both ends of the adjusting rod 31, that is, the support 17 and the frame 30 side are swingably connected via pins. Therefore, the support 17 can move up and down with respect to the main body 1, that is, up and down with respect to the road surface, but cannot move left and right in a direction perpendicular to the up and down movement. After all, the adjusting rod 31 constitutes a universal joint. The distance between the frame 30 and the support 17 is adjusted by adjusting the length of the adjusting rod 31. This adjusting mechanism has a well-known structure and is a type in which the nut 32 is rotated to adjust the length of the rod.

Castor wheels 35 are provided on both side surfaces of the support 17. The caster wheels 35 are the support 1
The distance between the road surface and the support 17 is adjusted. The caster wheel 35 is attached to the tip of a cantilevered rod 36 that is integral with the support 17. Upper and lower handles 37 are provided at the upper ends of the caster wheels 35. The caster wheels 35 are vertically moved by rotating the vertical handle 37.

By rotating the upper and lower handles 37, the height of the caster wheels 35, that is, the height of the endrel belt brush 25 from the road surface is changed. This depends on whether the height of the endless belt brush 25 from the road surface depends on whether the endless belt brush 25 is for dust, earth and sand, or for snow, and even if the endless belt brush 25 is for the same dust and earth and sand. Even if it is for dust, earth and sand, that dust,
This is because it also needs to be changed depending on the roughness of the earth and sand.
When the roughness of dust and earth and sand is large, the endless belt brush 25 is short and has a loose and rough texture, and when the roughness of dust and earth and sand is fine, the endless belt brush 25 is relatively large. Use soft and long-haired ones.

The method of replacing the endless belt brush 25 is the same as the method of removing the sprocket means in the normal transmission. In this way, the endless belt brush 2
Even if 5 is replaced and the height from the road surface is changed according to the object to be cleaned (dust, earth and sand, snow, etc.), the universal joint 1
4,14, that is, universal joints 14,14
However, since it is provided on the transmission shaft 15 and the output shaft 13, there is sufficient freedom so that the transmission shaft 15 is not burdened.

[0018] The operation dynamic following, described these working. Now, the engine 10 of the main body 1 is driven to clean dust, dirt, snow, and the like. Then, the rotation output of the engine 10 is the transmission box 11,
The endless belt brush 25 is rotationally driven via the output shaft 13, the universal joints 14, 14, the sprocket 18, the sprocket 21, and the pulley 22 to enter a cleaning standby state.

By operating the change lever 12 while holding the handle 3, the rotation of the engine 10 is transmitted to the tires 4 and 4. When the tires 4 and 4 are rotated by this transmission and moved forward, cleaning is started. That is, the endless belt brush 25 brush portion removes movement of dust, earth and sand, and snow on the road surface, and can clean dust, earth and sand, and the like in the width between the lower right end position and the lower left end position of the endless belt brush 25. is there. Normally, the road surface is inclined to the left and right, but since the endless belt brush 25 can be tilted freely due to the swinging of the universal joint 14, that is, the universal joints 14 and 14, and the adjusting rod 31, what kind of road surface is desired. Is also available. The direction of the moving road surface cleaner is changed by selecting one of the left and right clutch levers 5 and 5.

[0020]

[Other Embodiments] Endless belt brush 2 during cleaning
Rotated by 5 rotations (eg left rotation), dust on the ground,
The earth, sand, and snow are moved from the left side to the right side, but dust, earth, sand, and snow that have moved to the right side may be repelled. Further, the endless belt brush 25 may be moved into the bristles of the endless belt brush 25 and moved to the original position on the left side again. In order to eliminate such a situation, the pulleys 25 are used near the left and right ends of the support 17, that is, the endless belt brush 25.
A dust cover may be provided at a position corresponding to the upper part.

If a suction hose is attached to the dust cover via a suction port and connected to a suction fan built in the main body 1, the dust cover is repelled or put into the brush of the endless belt brush 25. It is possible to further increase dust collection and removal efficiency by sucking in dust, earth and sand, snow, etc. that are taken in and returned to the original state.

Of course, in the main body 1, if a duct or a hose is connected to the exhaust port for discharging the sucked dust, earth and sand, snow, etc., the main body 1 can be transferred and collected at any other place. By switching the clutch levers 5 and 5, it is possible to select left or right rotation. Therefore, when rotating to the right, suction of the left dust cover is performed, and when rotating to the left, the suction of the right dust cover is performed. The suction fan of the drive device main body may be operated in conjunction with each other so that suction works.
