2. Description of the Related Art Conventionally, the technology related to sweepers has been publicly known. However, in the conventional sweeper, since the blower casing and the suction case are integrally attached, there is a problem that the object is not sucked and remains when the suction surface is uneven. In addition, there is one in which a flexible tube is interposed between the blower casing and the suction case, and the suction case can be swung left and right, but the suction case extends forward, and not only does the machine become larger,
There is a drawback that suction resistance is increased and suction power is poor.

BEST MODE FOR CARRYING OUT THE INVENTION Next, embodiments of the present invention will be described. 1 is an overall side view of the sweeper of the present invention, FIG. 2 is an overall front view of the sweeper of the present invention, and FIG. 3 is an enlarged cross-sectional view of a portion of the blower 9 which supports the blower case 1.

The sweeper of the present invention is one in which an object to be sucked up is flipped up by a brush, sucked by a blower, and stored in a storage bag. In particular, it cleans dust such as pine needles on the green surface having a complicated inclination and undulation of the golf course. In the overall configuration of the sweeper of the present invention, a blower suction case 1, a blower device B, an engine 10, a transfer pipe P, and a bag A are placed on a carriage that is driven by the driving force of the engine 10. The blower device B is driven by the rotation of the engine 10. The blower device B is composed of a blower blade 9 and a blower casing 7, etc.,
Blower blades 9 are fixed to a blower drive shaft 25 that is also used as a crankshaft protruding from the engine 10. A pivot shaft 11, which will be described later, is fixed around the blower drive shaft 25.

In the present invention, the engine 10, the blower device B, the transfer pipe P, and the bag A itself placed on the trolley do not follow the undulation of the green, but the skirt 20 and the blower suction case 1 Or flip-up brush 16, gauge wheel 14, connecting material 15, swing arm 1
3 is configured to follow the undulation of the green by rotating the left and right end portions up and down about the pivot shaft 11.

In order to perform the above operation, the space between the blower device B and the blower suction case 1 is constructed as follows. A circular flange 3 is screwed to a collar portion 2 of a blower suction case 1 which constitutes a suction portion of the blower device B. The outer periphery of the circular flange 3 is supported by a plurality of rollers 4 which are rotatably supported on a blower casing 7 on the front of the blower device B, and the circular flange 3 and the blower suction case 1 are rotatable. Of. A collar portion 5 is formed on the roller 4, and the collar portion 5 is pressed by a disc spring 6,
It is pressed against the side surface of the circular flange 3.

The roller 4 is rotatably supported by a roller shaft 8 attached to a blower casing 7. The center of the outer circumference of the circular flange 3 is aligned with the blower drive shaft 25 which is the center of rotation of the blower blades 9 of the blower device B. A pivot shaft 11, which is loosely fitted around a blower drive shaft 25 that is a crank shaft of the engine 10, is fixed, and its axis is aligned with the axis of the blower blade 9.
The pivot shaft 11 constitutes a center for the blower suction case 1, the flip-up brush 16, the gauge wheel 14 and the like to rotate the left and right end portions up and down following the undulation of the green.

A bracket 12 is fitted on the pivot shaft 11, and the bracket 12 is supported by a predetermined amount so as to be rotatable left and right. The swing arm 13 is attached to the lower end of the bracket 12.
Are connected. The blower suction case 1, the flip-up brush 16 and the gauge wheel 14 are attached to the bracket 12, and the gauge wheel 14 and the flip-up brush 16 are allowed to rotate along the undulation of the green. It is configured accordingly. The blower suction case 1 and the flip-up brush 16 are rotated right and left along the green, but the circular flange 3 and the roller 4 are rotated so that the blower device B does not need to be partially rotated. Motion is allowed.

The gauge wheel 14 is connected to the swing arm 13 so that the vertical position can be changed. The lower part of the blower suction case 1 is connected to the swing arm 13 by a connecting member 15. The gauge wheel 14 follows the sloped surface of the green to attach the swing arm 13 and the connecting member 15 to the bracket 12.
Rotate around the to raise the flip-up brush 16 and the skirt 2.
It is configured so that 0 follows the green.

Reference numeral 16 denotes a flip-up brush for flipping up pine needles or the like, which is driven and rotated from the pivot shaft 11 of the engine 10 via V pulleys 19 and 18 and a flexible shaft 17. Reference numeral 20 is a skirt that covers the flip-up brush 16 and follows the surface of the green. 2
Reference numeral 1 is a drive wheel for transmitting and rotating the driving force from the engine 10 by shifting the driving force by a transmission case.

[0015]

As described above, the present invention has the following advantages. Since the blower suction case 1 is extended downward in front of the blower casing 7 and the blower suction case 1 is rotatably supported and connected about the axis of the blower device B, the blower suction case 1 is supported. The suction part of the sweeper composed of the skirt 20, the flip-up brush 16 and the blower suction case 1 follows the undulation and ups and downs of the green, and the suction residue of the target pine needles etc. is eliminated, providing a high performance sweeper You can do it.

A circular flange 3 is provided at the connecting portion between the blower suction case 1 and the blower casing 7, and the outer peripheral portion of the circular flange 3 is guided by a plurality of rollers 4 while the side surface of the circular flange 3 is provided. The blower casing 7 of the blower device B and the circular flange 3 of the blower suction case 1 can be used as they are as a pivot support portion, and the roller 4 is added. With this simple configuration, the blower suction case 1 that can follow the undulation of green could be constructed.

According to a third aspect of the present invention, the swing arm 13 pivotally supported around the axis of the blower device B is projected forward, a gauge wheel 14 is attached to the swing arm 13, and the swing arm 13 and the blower suction case 1 are attached. Since we have linked and
The heavy blower suction case 1, the flip-up brush 16 and the gauge wheel 14 are supported only by the blower casing 7 of the blower device B and the roller 4 provided on the circular flange 3 of the blower suction case 1. Although it is difficult, the swing arm 13 is supported by the pivot shaft 11, and the swing arm 13 supports the blower suction case 1 and the rotatable portion of the peripheral edge thereof. On the other hand, the strength of the support portion of the blower suction case 1 could be improved.
