Abstract

PURPOSE: To provide a reel-mower unit which has reel blades arranged on the periphery of the reel shaft and fan plates set radially around the reel shaft, thus blows out the cut grasses smoothly from the cutting reel. CONSTITUTION: Reel blades 19 are arranged on the periphery of the reel shaft 17 and fan plates 25 are radially mounted to the reel shaft. The grasses are cut by the rotation of the reel blades and the wind caused by the fan plates and the beating action of the fan plates blows out the cut grasses backward in the rear of the cutting reel 12.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reel mower device for mowing lawns and the like.

[0002]

2. Description of the Related Art As a reel mower device of this type, for example, a device disclosed in Japanese Utility Model Publication No. 4-18344 is known. As shown in FIG. 4, this reel mower device is provided with a plurality of cutting reels 51, and each of the cutting reels 51 has a reel shaft 52 that is driven to rotate about an axis and a reel shaft 5.
2 and a reel blade 53 that is spirally arranged around the circumference.

[0003]

However, in the conventional one, the grass mowed by the cutting reel 51 is blown backward by the wind caused by the rotation of the width of the reel blade 53. Therefore, the air volume became insufficient, and the cutting reel 51 was retained and carried around, resulting in defective discharge of long grass.
Also, when you attach a grass catcher, there will be defective discharge,
Since the wind generated by the spiral-shaped reel blade 53 approaches in one direction, there is a problem that the grass is also gathered toward one side and collected.

In view of the above-mentioned problems, the present invention is designed so that cut grass can be smoothly discharged from the cutting reel.

[0005]

A first technical means of the present invention for solving this technical problem is arranged around a reel shaft 17 which is driven to rotate about an axis and around the reel shaft 17. In the reel mower device including the cutting reel 12 having the reel blade 19, the fan plate 25 is provided in the radial direction of the reel shaft 17.

The second technical means is the fan plate 25.
However, they are arranged one by one between the adjacent reel blades 19.

[0007]

[Operation] Grass is mowed by the rotation of the reel blade 19,
The mowed grass is discharged to the rear of the cutting reel 12 by the wind raised by the fan plate 25 and the tapping action of the fan plate 25. Therefore, there is no shortage of the air volume, no retention or rotation occurs inside the cutting reel 12, no defective discharge of long grass occurs, and the cut grass is cut.
It is discharged smoothly from the inside.

[0008]

Embodiments of the present invention will now be described in detail with reference to the drawings. As shown in FIG. 3, the reel mower device 2 is attached to the front portion and the intermediate portion of the traveling vehicle 1. The traveling vehicle 1
The front wheels 3 and the rear wheels 4 are provided, the front wheels 3 are driving wheels, and the rear wheels 4 are steering wheels. The front frame 5 of the vehicle body projects further forward than the front wheel 3, and a steering handle 6 is erected on the front frame 5. An engine is mounted on the rear part of the vehicle body, and the engine is covered with a hood 7. A control seat 8 is arranged on the vehicle body between the steering wheel 6 and the hood 7.

A space for mounting the reel mower device 2 in the intermediate portion of the traveling vehicle 1 is provided by attaching the oil tank 9 which has been conventionally provided in the intermediate portion of the traveling vehicle 1 to the rear end portion of the traveling vehicle 1. The oil tank 9 is also used as a weight, and the oil tank 9 balances the weight with the reel mower device 2 in the front part of the traveling vehicle 1.

The reel mower device 2 is a support hanger 1
It is supported in a hanging shape through 1. The reel mower device 2 includes the cutting reel 12 shown in FIGS. 1 and 2, and each reel mower device 2 is provided with front and rear roller devices 13 and 14 for adjusting the cutting height. As shown in FIGS. 1 and 2, the cutting reel 12 includes a reel shaft 17 that is rotationally driven around an axis, and a reel blade holding plate 18 that is externally fitted and fixed to the reel shaft 17 at a predetermined interval. A plurality of reel blades 19 are arranged spirally around the reel shaft 17, and each reel blade 19 is fixedly engaged with a corner portion of the reel blade holding plate 18, and together with the reel shaft 17, a shaft center thereof. It is designed to be driven to rotate.
Further, the cutting reel 12 has a receiving blade 20 provided so as to face a lower portion of the reel blade 19, and a rear cover 21 provided behind the receiving blade 20 and the reel blade 1.
9 and an upper cover 22 that covers the upper outer periphery of

A plurality of fan plates 25 are projectingly provided on the reel shaft 17. This fan plate 2
5 is a reel shaft 17 between adjacent reel blade holding plates 18.
Are arranged in a radial pattern centered on each fan plate 25
Is welded to the reel shaft 17 and the reel blade holding plate 18. In addition, each fan plate 25 has an adjacent reel blade 1
They are arranged one by one between 9 spaces.

According to the structure of the above-described embodiment, the grass mowed between the receiving blade 20 and the reel blade 19 is removed from the upper cover 22 by the wind caused by the fan plate 25 and the hitting action by the fan plate 25. Rear cover 2
It is discharged to the rear of the reel vigorously from between 1 and. In addition,
In the above embodiment, the fan plates 25 are arranged one by one between the adjacent reel blades 19, but instead of this, a plurality of fan plates 25 may be arranged between the adjacent reel blades 19. .

In the above embodiment, the mowing grass is discharged from the inside of the cutting reel 12 to the rear outside, but instead of this, a grass collector is provided at the rear of the cutting reel 12 to cut the mowing grass. You may make it discharge | emit from the inside of the cutting reel 12 to a grass collector.

[0014]

According to the present invention, the wind raised by the fan plate 25 and the hitting action by the fan plate 25 allow the cut grass to be smoothly discharged from the cutting reel 12.
