Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blower drive device for a mobile vehicle.

[0002]

2. Description of the Related Art In the conventional moving vehicle of our company, the steering cylinder of the rear wheels and the blower drive shaft are concentrated on the right side of the machine body, and the steering operation is performed on the uneven road. When doing so, the steering angle could not be increased, and the tread of the rear wheels had to be widened, resulting in a machine with a slow turning motion.

[0003]

SUMMARY OF THE INVENTION The present invention is intended to solve the drawbacks of the conventional device, and has taken the following technical means. That is, the grass cutter 1 is provided at the front of the machine, the storage box 2 is provided on the engine 6 and the rear wheels 7, 7 at the rear of the machine, and the grass cutter 1 and the storage box 2 are connected by the lower shooter 3 and the upper shooter 4. In addition, a blower 5 is provided between the lower shooter 3 and the upper shooter 4, and the drive shaft 8 of the blower 5 and the steering cylinder 9 of the rear wheels 7, 7 are connected to the engine 6
A blower drive device for a moving vehicle, which is characterized in that it is arranged on the left and right sides of the vehicle in a distributed manner.

[0004]

The present invention has the following technical effects due to the above configuration. That is, since the drive shaft 8 of the blower 5 and the steering cylinders 9 of the rear wheels 7, 7 are arranged in a distributed manner on the left and right sides of the engine 6, both members in the vicinity of the engine 6 are located apart from each other, and the movement of the opponent is Because it is not restrained by, the rear wheel with a narrow steering angle and a large steering angle was realized, and it became a machine with a small turning on uneven road.

Embodiments of the present invention will be described in detail below with reference to the drawings. However, the dimensions, materials, shapes, relative positions, etc. of the components described in this embodiment are as follows.
Unless otherwise specified, the scope of the present invention is not intended to be limited thereto and is merely an illustrative example.

In the example shown in the drawing, the present invention is folded into a blower drive section for carrying the cut grass of the riding lawn mower 10 and arranged in the middle of the grass lawn transportation path. Riding lawn mower 1
In the case of 0, front and rear wheels 11, 7 are arranged at the front and rear four corners, and the left and right rear wheels 7, 7 are steered left and right by rotating the handle 12 left and right. When the handle 12 side is the front side in the traveling direction, the engine 6 is arranged at the rear part of the machine body, and is connected to the transmission case 13b at the front part of the machine body by the clutch housing 13a.

The engine 6 and the clutch housing 13
The main frame 13 of the machine body is constituted by a and the transmission case 13b. On the front part of the machine body main frame 13, the mower 1 is suspended via links 14, 14. Reference numeral 15 is a hydraulic cylinder that moves the grass cutting tool 1 up and down.

Reference numeral 16 is a seat on which the driver sits down during work and puts his / her feet on the step 17. A shaft 19 to which a drive pulley 18 is attached is provided at the rear of the engine 6 in a projecting manner.
A driven pulley 20 attached to the rear part of the drive shaft 8 on the left side of the machine body
Power is transmitted to and from via an interlocking connector 21 such as a V-belt.

A drive case 22 in which a bevel gear is housed is provided at the front of the drive shaft 8 and rotates a rotary shaft 23. Rotating shaft 2
3 is supported through the clutch housing 13a to the right,
The blower 5 is attached to the shaft end of the rotary shaft 23. Blower 5
Is arranged between the lower shooter 3 and the upper shooter 4,
By this blower 5, turfgrass mowed by the mowing tool 1
Storage box 2 from lower shooter 3 through upper shooter 4
Reach

The rear wheels 7, 7 have an axle housing 24.
The left and right are connected by the final cases 25, 25 that rotate at their ends, and as described above, by rotating the handle 12 left and right, high-pressure oil enters and leaves the steering cylinder 9 to control expansion and contraction, and steering is performed via the knuckle arm 26. Manipulate.
Reference numeral 30 denotes a tie rod, which interlocks and connects the final cases 25 of the left and right rear wheels 7, 7.

The axle housing 24 is the main frame 1
By the center pivot 27 provided in 3, the rear wheels 7 and 7 swing up and down when traveling on the uneven road. The area around the engine 6 is covered with a bonnet (not shown) that is a cover, and the storage box 2 is attached to the outside and above the hood. Although not shown, when the inside of the storage box 2 is filled with turf grass, the storage box 2 is lifted up and the rear lid 28 is opened to discharge the turf grass inside into an external carrier.

In the illustrated example, the rotary shaft 23 is pierced and supported with respect to the clutch housing 13a, but when the left-right relationship between the drive shaft 8 and the steering cylinder 9 is reversed, the rotary shaft 23 may simply be mounted and supported on the side wall.
