Description

DETAILED DESCRIPTION OF THE INVENTION The present invention removes the original working tools attached to construction machines, snowplows, road maintenance machines, etc., and mounts the device according to the present invention to clean the road surface of the sidewalk. This invention relates to a cleaning device.

In snowy regions, snow on sidewalks is not removed during the winter, or even if it is, it is usually piled up high at the border between the road and the sidewalk, and the asphalt powder scraped off by spiked tires accumulates throughout the winter. It is well known that dust particles are mixed in and accumulated in the snow, and after the snow melts in the spring, they suddenly become apparent and become car dust pollution. For roadways, it is possible to collect wintering mud using existing large-scale cleaning equipment, but for sidewalks, there are restrictions on heavy objects, size, etc.
Mechanical construction is difficult because the low curbs for vehicles to cross, as well as plants and utility poles, are in contact with the road, so the current situation is that everything is done manually. Some attempts have been made to use a boarded brush for cleaning building floors, but the capacity is small and it is impossible to remove winter mud that has been stuck for several months. , which has the paradox of not being able to be raised onto the sidewalk.

The present invention aims to fully solve this problem, and its gist is to mount a road cleaning device in front of a working vehicle, extend it from the road side to the sidewalk side, and rotate the rotary brush attached to the tip. At the same time, the device is capable of sweeping garbage and wintering mud on the sidewalk onto the road by driving a work vehicle.

The details of one embodiment will be described below with reference to the drawings.

1 is a road cleaning device of the present invention, and its configuration is as follows. A first support 4 is installed at a side position of a pedestal 3 attached to the front surface of the working vehicle 2 so as to be rotatable from the traveling direction F of the working vehicle 2 toward the sidewalk direction F'. This rotation of the first support 4 is caused by the above-mentioned mount 3.
This is performed by the first hydraulic cylinder 4A disposed above.
Further, an arm 5 is connected to this first support 4 with a pin 5A, and a pin 5 is attached to the tip of this arm 5.
A second support 6 is connected to the first support 4 in parallel via B. 7 is a second hydraulic cylinder stretched between the first support 4 and the second support 6 in a state parallel to the arm 5; 8 is the first support 4;
and a third hydraulic cylinder stretched between the arm 5 and the arm 5. Further, a support frame 9 in a horizontal state is rotatably connected to the second support column 6. The support frame 9 is rotated by a fourth hydraulic cylinder 10 stretched between the second support column 6 and the support frame 9, and a known cleaning brush 11 is rotatably mounted on the support frame. installed. In the figure, P is a pin.

Next, the operation of the present invention will be explained together with its effects.

When working, the support frame 9 is rotated outward about the supports 4 and 6 so that it moves from the traveling direction F to the sidewalk direction F' and is extended onto the sidewalk. Figure 2 shows the working condition. That is, the support frame 9 to which the cleaning brush 11 is mounted is rotated outward to a predetermined position by the hydraulic cylinder 10, with the support frame 6 as the center of rotation. Similarly, the hydraulic cylinders 7 and 8 supporting the support frame 9 and the arm 5 are rotated outward about the support column 4 by the hydraulic cylinder 4A and placed on the sidewalk. FIG. 3 is a detailed diagram of the link motion. By expanding and contracting the cylinder 8, the distance between the sidewalk and the brush 11 is adjusted, and by expanding and contracting the hydraulic cylinder 7, the inclination of the brush 11 is adjusted to follow the sidewalk. do the work. If the work vehicle moves forward at a predetermined speed while rotating this brush 11 using a known method using a hydraulic pump, hydraulic motor, etc., garbage on the sidewalk or the above-mentioned wintering mud can be swept to the roadway side. can. The work vehicles that support the support frames and brushes are located on the roadway, so
Unlike the case where it is on the sidewalk, there are no restrictions on weight or size, and it is possible to secure any size and power source that can sufficiently perform the work. In addition, this device can support any type of sidewalk by adjusting the expansion and contraction of the hydraulic cylinders 7 and 8, regardless of the shape of the sidewalk, such as sidewalks of different heights, sidewalks with slopes, or low curbs provided for vehicles to cross. The frame 9 can be reliably aligned with the sidewalk surface, and as a result, uniform cleaning work can be performed without unevenness. Furthermore, since this device is placed at the front of the work vehicle, passersby and obstacles can be easily seen from inside the driver's cabin, making it possible to carry out work safely and efficiently.
