Field of the Invention The present invention relates to a lightweight object selective suction device for selectively sucking only lightweight objects such as cigarettes, dust, and dead leaves on a gravel road surface that are scattered on the tracks under the railway platform.

[0002]

2. Description of the Related Art Conventionally, in order to selectively remove only light objects such as cigarettes, dust, and dead leaves on gravel roads, which are scattered on the tracks under the railway platforms, they must be manually removed one by one. I was cleaning. It may be possible to use a vacuum cleaner with a strong suction force to remove lightweight objects, but if the suction force is simply increased, it is possible to suction heavy objects such as stones and gravel as well as lightweight objects. It is not desirable.

[0003]

Therefore, in the end, it is more reliable and more efficient to remove the lightweight material by hand, and it has been difficult to mechanize and improve the efficiency.
An object of the present invention is to provide a lightweight object selective suction device capable of selectively sucking only lightweight objects.

[0004]

The above object is to provide a suction part having a traveling part that travels on a suctioned surface for sucking a lightweight object, and a suction port that is mounted on the traveling part and faces the suctioned surface. The duct and the first region of the suction port of the suction duct generate wind in the first direction from the surface to be sucked toward the suction port, and the second region of the suction port of the suction duct receives the air from the suction port. A turbulent airflow generating means for generating a turbulent airflow on the suctioned surface by generating a wind in a second direction toward the suction surface, and a turbulent airflow generated by the turbulent airflow generation means flying a lightweight object existing on the suctioned surface. It is achieved by a lightweight object selective suction device characterized in that the lightweight object is selectively sucked by the wind in the first direction by the turbulent airflow generating means.

[0005]

According to the present invention, a traveling portion that travels on a surface to be sucked for sucking a lightweight object, a suction duct that is mounted on the traveling portion and has a suction port that faces the surface to be sucked, and a suction duct The first area of the suction port generates a wind in the first direction from the suction surface to the suction port, and the second area of the suction port of the suction duct generates a wind in the second direction from the suction port to the suction surface.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A light weight object selective suction device according to an embodiment of the present invention will be described with reference to FIG. 1A is a front view of the lightweight object selective suction device, and FIG. 1B is a side view thereof.
(C) is a bottom view. In the lightweight object selective suction device 10 of the present embodiment, a device body 12 having a streamlined appearance is mounted on a traveling carriage 11 that travels on a surface to be sucked such as a gravel road surface that sucks a lightweight object such as cigarette butts. It has a configured configuration.

The traveling vehicle 11 travels on the surface to be attracted by driving the caterpillar 16 by the traveling motor 14. Since the surface of the gravel road or the like has an uneven shape, the caterpillar 16 is used for smooth traveling. A suction duct 18 for sucking a lightweight object is formed inside the device main body 12 mounted on the traveling carriage 11. The suction duct 18 has a so-called bell mouth shape, and its suction port 20 is opened between the caterpillars 16 of the traveling carriage 11 and faces the suction surface. The suction port 20 is provided with a propeller 22 for generating a turbulent air flow. The propeller 22 is rotationally driven by a propeller motor (not shown). The distance between the suction port 20 and the surface to be sucked is preferably about 30 to 40 mm in order to maintain static pressure.

The suction duct 18 in the apparatus main body 12 has a shape that extends vertically upward from the suction port 20 and then bends to the rear by approximately 90 degrees. In the present embodiment, by devising the shape of the edge 24 of the bent portion of the suction duct 18, a turbulent air flow suitable for selectively sucking only lightweight objects is generated in the vicinity of the suction port 20. That is, instead of making the shape of the edge 24 of the suction duct 18 parallel to the surface of the suction port 20, as shown in FIG. 1 (a), it has an inclined shape in which the left side is slightly lowered when viewed from the front. . The inclination angle θ of the edge 24 is preferably within the range of approximately 7-14 degrees. The details of the turbulent air flow will be described later.

A dust box 26 for accommodating the sucked lightweight object is provided at the bent rear lower portion of the suction duct 18. Work lamps 28 for illuminating the front side in the traveling direction are provided on the left and right sides of the apparatus main body 12, and a work lamp 30 for illuminating the rear side is provided on the rear side. A screen 32 is provided above the work light 30.

Around the suction port 20 of the apparatus main body 12, a static electricity generating member 34 for generating static electricity and sucking a lightweight object.
Is provided. In addition to directly sucking light objects such as butts on the surface to be sucked, it also sucks light objects fluttered by turbulence and complements selective suction due to turbulence to completely remove light objects on the surface to be sucked. I am trying to do it.

Next, the lightweight object selective suction device 10 of the present embodiment.
The generation state of turbulent air flow due to will be described in detail. Fig. 1 shows the state of wind generated by rotating the propeller 22.
It is indicated by an arrow inside. The propeller 22 is rotated to generate wind in the direction in which air is sucked from the suction port 20 as a whole, but since the suction duct 18 is bent 90 degrees, the air flow sucked from the suction port 20 is As shown in FIG. 1 (b), the upper air flow directly flows to the rear of the suction duct 18, but the lower air flow collides with the edge 24 of the bent portion and flows in the direction opposite to the suction. Therefore, the rotation of the propeller 22 causes the airflow to flow toward the suction duct 18 as a whole, but the suction duct 1
In the vicinity of the suction port 20 of FIG. 8, a clockwise airflow is generated around the propeller 22 on the surface of FIG.

Further, since the edge 24 of the bent portion is inclined so that the left side is low and the right side is high, as shown in FIG. Becomes Therefore, on the left side of FIG. 1 (a), the air flow is basically upward, or on the right side, the air flow is relatively downward, and eventually the propeller 22 is centered near the suction port 20 of the suction duct 18. And, Figure 1
A clockwise airflow is generated on the plane (a).

After all, the clockwise airflow shown in FIG. 1 (a) and the clockwise airflow shown in FIG. 1 (b) are mixed, and a certain partial area is provided in the vicinity of the suction port 20 of the suction duct 18. Creates an air flow in the suction direction, and an air flow in the opposite direction to the suction in another part of the region, and these air flows are mixed to generate a turbulent air flow. This turbulent air flow not only lifts the lightweight objects on the surface of the attracted surface, but also stirs the vicinity of the surface of the attracted surface to lift up the lightweight objects buried inside.

Most of the lightweight objects that are lifted up by the turbulent air flow are sucked in the suction duct 18, and the insufficiently sucked lightweight objects are sucked by the static electricity generating member 34 around the suction port 20. In this way, it is possible to selectively suck only the lightweight object on the surface to be sucked. For example, the lightweight object selective suction device 1 according to the present embodiment is provided on the gravel road surface of the railroad under the train platform.
If 0 is run, only lightweight materials such as cigarette butts can be selectively sucked and completely removed without sucking gravel.

Even when light objects such as dead leaves are scattered on the gravel road, when the lightweight object selective suction device 10 of the present embodiment is run, only lightweight objects such as dead leaves and dust are sucked without sucking gravel. Can be selectively sucked and cleaned cleanly. It should be noted that by using the lightweight object selective suction device of the present embodiment, suctioning a suctioned surface such as a floor surface enables more clean cleaning than with a normal suction cleaner.

Next, the lightweight object selective suction device 10 of the present embodiment.
An operating device 40 for a lightweight object selective suction device for causing the vehicle to travel on a track under a railway platform will be described with reference to FIGS. 2 and 3. FIG. 2A is a rear view of the operation device for a lightweight object selective suction device as viewed from the rear, and FIG. 2B is a side view.

In the operation device 40 for the lightweight object selective suction device,
As shown in FIG. 2, a traveling tire 44 is provided on the bottom surface of the traveling carriage 42 on which the lightweight object suction device 10 is mounted, and a stairway traveling speed reducer 46 for raising and lowering stairs is provided. The stairs to the platform are moved up and down by the stairway traveling speed reducer 46, and travel on the platform by the traveling tires 44.

At the rear part of the traveling carriage 42, there is provided a driving console 48 for driving the driving device 40 for the lightweight object suction device, and in the operating console 48 is light together with the operating device 40 for the lightweight object suction device. A generator 50 for driving and driving the object selective suction device 10 is provided. At the center of the traveling carriage 42, an arm lifter 52 for lowering the lightweight object selective suction device 10 onto a track under the platform is provided, and an arm lifter speed reducer 58 for driving the arm lifter 52 is provided. The arm lifter 52 is composed of two connected arms 54 and 56.
One of the arms 54 is a driving device 40 for the lightweight object suction device.
Of the traveling carriage 42, and the other arm 56 is connected to the traveling carriage 11 of the lightweight object selective suction device 10. Both arms 54 and 56 are connected above the lightweight object selective suction device 10.

When the operation device 40 for the lightweight object suction device is driven to reach the platform near the track surface, the arm lifter speed reducer 58 decelerates the arm lifter 52. As shown in FIG. 3, the arm lifter 52 rotates to lower the lightweight object selective suction device 10 onto the orbit under the platform. After that, the lightweight object selective suction device operating device 40 is driven along the side edge of the platform, and the lightweight object selective suction device 10 selectively sucks and cleans the lightweight object on the track. The operation device 40 for the lightweight object suction device is run from one end of the platform to the other to clean the orbit.

As described above, by using the driving device 40 for the light weight selective suction device, it is possible to mechanically and efficiently remove dust such as cigarette butts falling between the railway platform and the railroad track. The present invention is not limited to the above embodiment, and various modifications can be made. For example, in the above embodiment, the edge of the bent portion is inclined so that the left side is low and the right side is high in order to generate the turbulent air flow. However, conversely, it may be inclined so that the right side is low and the left side is high.

In the above embodiment, turbulent air flow is generated by bending the shape of the suction duct and making the edge shape of the bent portion unbalanced left and right. Turbulence may be generated.
