Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a green maintenance work device for performing maintenance work on the green turf of a golf course.

Once grass is planted, it must remain green semi-permanently, so care must be taken to prevent the underground parts, including the underground rhizomes, from aging. For this reason, it is important to add top soil so that as many fine roots as possible emerge from the underground stems, and fine roots also emerge from the lower parts of the upright stems. In other words, the purpose of the top soil is to allow new underground rhizomes of the grass to enter the top top soil and help with renewal, and to even out unevenness on the surface of the grass to create a smooth surface. The key is to create a favorable environment for rooting, including darkness and soil temperature.

Therefore, when maintaining the grass on golf course greens, it is important to add soil to a thickness of approximately 0.5 mm to 4.5 mm after mowing the grass.

[Prior art and its problems to be solved]

Conventionally, in order to perform this top dressing, a top soil spreader was used to spread top soil onto the green grass by approximately 0.5 mm to 4.5 mm.
It is evenly distributed to a thickness of mm. However, simply spreading top soil on the lawn does not constitute top soil filling. This tendency is particularly noticeable in bent grass, but in general, after spreading the top soil, use a rake-like brush to thoroughly penetrate the top soil into the roots of the grass, and then even out the top soil and apply it to the grass. Rolling is performed using rollers to flatten the surface.

Since the above-mentioned brushing work is done manually, it takes 2 to 3 days even if 18 people work to fill 18 holes, resulting in a large amount of expense for green maintenance.

The present invention was made in order to solve the above-mentioned conventional problems, and the purpose is to provide a green maintenance work device that is effective in reducing the cost of soil filling for green maintenance. There is.

[Means for solving problems]

The means for solving the above problem includes a front wheel that can be operated by a handle, a wide brush placed in front of the front wheel, and a pair of left and right brushes placed behind the front wheel at positions that do not overlap with the width of the brush. It is equipped with wide brushes and a rear wheel that also serves as a roller that is rotated by a drive source behind the pair of brushes.

[Effect]

By simply driving over the green while operating the handle, the worker can brush the top soil sprinkled on the green and then compact it with rollers, instead of manually doing it as in the past. Brushing and subsequent roller application can be performed simultaneously and easily.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings. The drawings show an embodiment of the present invention; FIG. 1 is a side view, FIG. 2 is a partially omitted plan view, and FIG. 3 is a front view. In the figure, 1 is the vehicle body, 2
is a front wheel provided at the center of the vehicle body 1 in the forward direction;
3 is the handle that operates the front wheel 2, 4 is the handle 3
5a and 5b are a pair of rear wheels that act as rollers that are installed closely on the left and right at the rear of the vehicle body 1 in the forward direction; 6 is a power source for driving the rear wheels 5 to make them roll; The rotational force of the engine 6 is transmitted to each of the rear wheels 5a and 5b via a differential mechanism and a chain 7 (not shown).

8 is a front brush fixed to the vehicle body 1 so as to be located in front of the front wheel 2, and 9a and 9b are rear wheels 5.
The front brush 8 is provided to brush the area that cannot be brushed by the rear brushes 9a and 9b.

With the above configuration, by running the device according to the present invention on the green where top soil has been spread by the top soil spreader, the top soil can be brushed 8, 9a, 9b.
Immediately after the soil is brushed and thoroughly penetrated into the roots of the grass, it is evenly rolled and compacted by rollers 5a and 5b, and the soil is topped with no irregularities.

At this time, the differential mechanism provided between the rollers 5a and 5b allows the direction of the vehicle body 1 to be smoothly changed by operating the handle, reducing the need to apply excessive force to the grass, thereby preventing damage to the grass. .

In addition, in the above-mentioned embodiment, the driving force is applied to the rear wheels 5a,
5b, but it may also be transmitted to the front wheels. Further, the number of rear wheels does not necessarily have to be one pair.

Further, in the above-described embodiments, top soil is spread using a separate spreader, but the spreader may also be mounted on the vehicle body 1. In this case, the front of seat 4 or the front wheel 2
It is preferable to provide a top soil tank in front of the brush 1 and to provide the front brush 8 at a corresponding position immediately in front of the rear brushes 9a and 9b.

[Effect of idea]

As mentioned above, this invention has wheels that also serve as rollers and have a width that is approximately the same as the width of the brush.
Brush the top soil sprinkled on the green with a brush to ensure that the top soil gets into the roots of the grass, and use wheels that also serve as rollers.
It is easy to apply soil evenly and without unevenness, and since it is brushed with a brush and then applied with a roller, the grass surface is clean and the finish is beautiful. It is effective.
