Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dust collecting device that can be used as a cleaning vehicle for golf courses, parks, roads, etc., or as a grass collecting vehicle.

In conventional collection devices of this kind, the air that sucks and transports the dust that has been stirred up is directly discharged from the tank to the outside, so fine dust and the like are discharged to the outside along with the exhaust air, polluting the atmosphere. There were drawbacks.

This invention was made in order to eliminate the drawbacks of the conventional device described above, and it is an ideal device for removing dust, etc., by making the wind that transports the dust into a circulating air, thereby eliminating the release of any dust, etc. to the outside. The purpose is to provide a collection device.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. In the figure, (1) is a vehicle platform on which the present device is mounted, which is towed or towed by a towing vehicle (not shown). (2) is a sealed tank placed on the vehicle chassis (1), and has an upper input port (2a) and an outlet with a sealed lid (not shown). (3) is a rotating brush that is located under the chassis (1) and has a length that is the full width of the chassis (1).
(5) is a pair of left and right arms that support the horizontal shaft (4), and is rotatably inserted into the shaft (4) and acts as a scraping member for scraping up dust, etc. (5) is a pair of left and right arms that support the horizontal shaft (4). The base end of the arm is attached to the chassis (1) so that the tip can move up and down.
installed on. (6) is a cover that covers the rotating brush (3) to form a collection chamber (6a), and the horizontal axis (
4). (7) is an engine for driving the rotating brush (3).
) is being driven. (9) is a circulating air system placed on the chassis (1) between the tank (2) and the rotating brush (3), and has an inlet (901), an opening at the center of the upper part of the cover (6), and an outlet. (902) is when the closed tank (2) is charged Ill (
2a) into the tank, a blower (9b) provided in this outgoing path (9a), and an inlet (903) opening in the center near the outlet of the outgoing path (9a). The outlet (904) is constituted by a return section (9C) that opens into the cover (6) adjacent to the entrance of the outward section (9a). The outward path portion (9a) includes a fan chamber (906) formed within the main body (905) on the chassis (1);
A centrifugal separator u (907), which is also in the main body (905) and has the outlet (902), and compartments (906,), (
907), the passageway (908) that connects the fan room (906)
and having said inlet (901)”
J flexible duct (909). The return section (9c
) consists of a flexible duct (9), O), which is attached to the main body (905) so that its inlet (903) is located linearly in the center of the centrifugal chamber (907). (
10) is the engine for driving the blower (9b).
11) The fan is driven by transmission.

The operation of this device will be explained using a golf course cleaning vehicle connected to a towing vehicle (for example, in FIG. 1, a power vehicle is connected to the left side of the chassis (1) and pushed toward the right).

When both engines (7) and (10) are driven at the site, the blower (9b) blows the inlet (90) of the duct (909).
Air is sucked in from 1) and ejected from the fan chamber (906) through the passage (908) into the centrifugation chamber (907), creating a spiral flow inside the centrifugation chamber (907) as shown by the arrow (X). occurs. This air, which has filled the airtight tank (2) and has nowhere to go, enters the duct 1- (910) in the center of the centrifugal separation chamber (907) and returns directly to the collection chamber (6a). and then reheat the blower (9b)
is sucked into the entrance (901) of the duct (909). In this way, the circulating wind (X
) occurs. A rotating brush (3
) The garbage, leaves, etc. that are raked up by the
Riding the circulating air (X) inside the storage room (6a), the fan window (9
06), passes through H8 (908), centrifugation chamber (907), is ejected to outlet (902), and is stored in tank (2) as it is. Centrifugal separation of dirt and dust ￥90
7) and the tank (2), and then enters the return path (9c) together with the circulating wind (X) and circulates again.

When the work is finished, both engines (7) and (10) are completely stopped, and when the hydraulic cylinder is operated to activate the image arm (5) and lift the horizontal shaft (4), the rotating brush (3) moves into both ducts. Bend (909) and (910) to cover (6)
It will also rise and move away from the ground, so you can move in this state.

As described above, this invention uses circulating air to lift up dust and transport it into the tank, so that once the dust is sucked up, the particles in the dust are not scattered with the exhaust air, and the dust is completely removed. It has an effect that can be collected. Therefore, there is no need to worry about air pollution during work, and it is highly effective as a cleaning device for golf courses, roads, parks, etc., and can also be used as a grass collecting device, which has a wide range of uses. be.

In the above embodiment, a movable type using a chassis (1) was shown, but this may be a fixed type, or the rotating brush (3) and the blower 1 (9b) may be driven by the same engine. good.

Furthermore, in the above embodiment, if a cutting blade is provided in front of the rotary brush (3), it is possible to perform mowing and mowing at the same time as cleaning, that is, mowing and cleaning at a golf course or the like can be done at the same time. Note that the scraping member does not need to be the rotating brush (3) as long as it can scrape up dust and the like.
