Japanese Unexamined Patent Publication No. 2000-17879 JP 2006-117799 A

  Patent Document 1 discloses a flow in the direction of a suction duct by rotating a propeller in order to selectively remove only light objects such as cigarettes, garbage, and dead leaves scattered on a track under a railway platform. An air flow and an air flow that collides with the edge of the bent part and flows in the opposite direction to the suction are generated, thereby generating a turbulent airflow so that the buried lightweight object can be raised. Since sand and pebbles having a weight less than the light weight contained in are sucked in, the problem that the propeller is damaged by these solid matters also arises.

  In Patent Document 2, a lightweight object and a heavy object are simultaneously sucked by the suction force of the dust collector, the light object raises the inclined wind tunnel and the zigzag wind copper, and the heavy object is the floor of the inclined wind tunnel and the zigzag wind tunnel. Both are separated by falling down along the surface, but the light and heavy objects that have lifted the air transport pipe by the suction force of the dust collector are the inclined wind tunnel and zigzag that have the same suction force. It is difficult to sort efficiently in a wind tunnel.

  Therefore, the present invention provides a suction device capable of efficiently sucking dust regardless of a propeller, and also provides a lightweight object suction processing device including the suction device.

  The suction device according to the present invention includes a suction pipe having suction and exhaust ports at both ends thereof, and an air passage which is located on the outer periphery of the suction pipe and whose cross section is reduced toward the peripheral edge of the discharge port of the suction pipe. A blower pipe that blows air from the peripheral edge of the discharge port of the suction pipe toward the discharge direction of the suction pipe, and a blower unit that sends air to the blower pipe, and a peripheral part of the discharge port of the suction pipe In addition, a plurality of notches are formed at predetermined intervals in the circumferential direction of the discharge port. In addition, as a ventilation means, it is desirable that it is an electric motor.

  As a result, when air is sent to the blower tube by the blowing means, air is blown out in the discharge direction from the periphery of the suction port of the suction tube, whereby the air in the suction tube is pulled and sucked into the suction port of the suction tube. Force is generated.

  In addition, a notch having a predetermined shape, for example, a semicircular shape, a semielliptical shape, a wedge shape, or a rectangular shape, is formed on the periphery of the exhaust port of the suction pipe. The inventor has found that the suction force of the suction pipe is increased by forming a notch in the periphery of the exhaust port of the suction pipe by the blower pipe. Although the principle is unknown, it is assumed that the amount of air taken in the suction pipe increases due to the turbulent flow resulting from the disturbance of the wind speed and volume of air blown to the periphery of the exhaust port of the suction pipe Is done.

  Further, since the suction force of the suction pipe is proportional to the air volume of the blowing means, it is possible to change the suction volume of the suction pipe by adjusting the air volume by the blowing means. As a result, for example, when sucking a lightweight object such as a cigarette butt, it is possible to avoid sucking a heavy object such as a pebble by blowing an air volume of only a brush. In addition, when a tree is felled, it is possible to suck only the branches and leaves that have been cut by setting the air volume corresponding to that.

  Moreover, according to this invention, it is desirable to provide the air passage of the said blast pipe with the air rotation mechanism which rotates the air ventilated by the ventilation means helically. Accordingly, a rotational force can be applied to the air blown from the blower tube to the periphery of the exhaust port of the suction tube, so that the suction force of the air in the suction tube can be further improved.

  Furthermore, it is desirable to provide a damper mechanism for opening and closing the air exhaust port of the air duct at the air exhaust port of the air duct. By providing a damper mechanism that opens and closes the air exhaust port of the blower pipe, when this damper mechanism is closed, air can flow back to the suction pipe, so that it can also be used as a blower. In addition, when a light object sucked into the suction tube is caught and the suction force is reduced, the substance caught by blowing into the suction tube can be discharged, so that the suction force can be restored. It is.

  Further, according to the present invention, the above-described suction device according to the present invention, a flexible hose connected to the suction port of the suction tube of the suction device, and the dust storage space in which the discharge port of the blower tube of the suction device opens. It is desirable to provide a lightweight object suction processing device comprising:

  Furthermore, by providing this lightweight object suction processing apparatus on a loading platform such as a light truck, the lightweight object suction processing apparatus can be moved. In this case, a sirocco fan or the like as a blowing means can be used by being directly connected to the vehicle engine.

  Moreover, the air discharged | emitted can be purified by providing an air purification apparatus in the downstream of a lightweight thing suction processing apparatus.

  As described above, since the suction device according to the present invention is not a propeller type, it has an effect that the sucked lightweight dust can be collected without being caught. Further, it is possible to easily control the suction force by controlling the amount of air blown by the blower means, and in particular, it is possible to efficiently suck the butts, branches and leaves, and papers.

  According to the present invention, the suction device can be switched as the blower with a simple structure.
