Description

[Detailed description of the invention] [Field of application of the invention] The invention relates to a brushing device that has a plurality of removable brushes, and is particularly useful for the maintenance and management of grass laid at golf courses, tennis courts, gardens, etc. The present invention relates to a brushing device suitable for leveling the ground of baseball fields, various grounds, etc.

For example, when maintaining and managing the grass on greens at golf courses, etc., it is necessary to prevent the aging of the underground parts, including the rhizomes, so it is necessary to bring out as many fine roots as possible from the underground rhizomes, and also from the lower part of the upright stems. It is important to add top soil for this purpose.
The purpose of this top soil is to allow the new rhizomes of the grass to enter the top soil and help with renewal, and to even out the unevenness of the grass surface to create a smooth surface. It is necessary to add top soil to a thickness of 0.5 mm to 4.5 mm and use a brush to rub the top soil into the lawn. Additionally, rake-like levelers and brushes are used to smooth and homogenize soil and gravel on various grounds.

[Prior art]

Conventionally, in order to apply soil to the lawn as described above, a top soil spreader is used to spread top soil onto the lawn, and a brushing operation is performed to thoroughly rub the top soil into the roots of the grass. The turf surface is then smoothed by rolling it with rollers. At present, such brushing work is performed manually using a rake-like brush, which requires a great deal of cost and labor.

Therefore, the inventor of the present invention first applied for a green maintenance work device that is effective in efficiently carrying out soil filling work for green maintenance and significantly reducing the cost and labor required for green maintenance management. −70483

[Purpose of invention]

The present invention solves the above-mentioned conventional problems, improves the brush part of the previously proposed maintenance work device, and incorporates it into the maintenance work device or replaces it with a known lawn mower or bunker. By incorporating it into the machine, you can perform precise soil filling work on lawns such as golf courses and tennis courts, and leveling work on grounds, etc., as well as appropriate brushing work depending on the type of grass such as Korai grass and bent grass. An object of the present invention is to provide a brushing device capable of performing the following steps.

Another object of the present invention is to provide a brushing device that can perform appropriate soil filling and leveling regardless of the undulations or unevenness of the topography of golf course greens, grounds, parks, etc.

〔overview〕

In order to achieve the above objects, the brushing device according to the present invention includes a first board that is attached to the green maintenance work device, and a brushing device that is attached to the first board via a connecting member such as a hinge so as to be rotatable in the vertical direction. and a plurality of brushes of different thicknesses and lengths that are detachably attached to a plurality of attachment parts formed on the lower surfaces of the first and second substrates. .

The above-mentioned brush device may be provided with a connecting means on one of the substrates to be incorporated into various power devices.

〔Example〕

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

1 and 2 are perspective views showing different embodiments of the present invention, respectively. The brush device according to the present invention basically includes a plurality of brushes 1a, 1b, 1.
c, and a substrate 2a equipped with each of these brushes,
2b. In the embodiment shown in FIG. 1, a total of five brushes consisting of three types of brushes are mounted in parallel on two boards 2a and 2b, and one board 2a has the longest and largest diameter brush. A brush 1a and a brush 1b having an intermediate length and diameter are attached, and three brushes 1c having the shortest and smallest diameter are attached to the other substrate 2b. For example, hair lengths of 110, 80, and 30 (mm), and hair diameters of 0.6, 0.5, and 0.3 (mm) are used. By selecting and using an appropriate brush depending on the situation, precise brushing work can be performed.

The two substrates 2a and 2b are connected to one substrate 2 by a connecting member 3 such as a hinge provided on the upper surface thereof.
The other board 2b is connected to the board 2b so as to be swingable at an appropriate angle as indicated by an arrow 4. As a result, reliable brushing work can be performed regardless of the undulations of the grass surface or sandy soil during soil filling, which will be described later.

Referring to FIG. 2, mounting portions 5a to 5c for mounting the plurality of brushes described above are mounted on the substrate 2a.
and attached to the lower surface of 2b. These mounting parts 5a to 5c each consist of a pair of rails corresponding to the number of brushes 1, and the converging rods 1a ₁ to 1c ₁ of the brushes are removably inserted thereinto and slid thereon. In addition to the rail shown in the figure, mounting methods include
Appropriate mounting means can be used, such as engaging with the convergence rod or clamping it.

The brush device shown in FIG. 3 is a perspective view with two rods 6 provided for support to the power plant. This rod 6 is fixed upright on one of the substrates 2a, and the tip of a telescoping rod 7 connected to, for example, a power device is inserted into and engaged with this rod 6. This engaging portion allows the brush device to swing vertically and horizontally (swing).
For example, the tip may be formed into a spherical body 8, or a suitable ball bearing or the like may be inserted.

Next, an example of the use of the present invention will be explained with reference to FIG. In this example, a state in which a brushing device according to the present invention is attached to a green maintenance work device 20 previously proposed by the present inventor is shown. The brushing device is removably attached to the telescopic rod 21 of the green maintenance work device by a suitable locking means (not shown) via a rod 6 connected to one of the substrates 2a. This telescoping rod 21 is powered by a known hydraulic drive source 2 such as a hydraulic pump or a hydraulic cylinder.
2 and a motor, and is extended during operation so that the tip of the brush touches the ground.

Now, if the driving source 23 of the device 20 is activated to start raising the grass on the green, for example, if the device 20
When there are undulations (undulations) in the green along the running direction, the connection member 3 that movably connects one board 2a of the brushing device to the other board 2b causes the other board 2b to move. By moving up and down, not only the brushes 1a and 1b but also the tips of each group of brushes 1c are constantly pressed against the grass surface.

Furthermore, as shown in FIG. 3, by movably connecting the rod 6 and the telescopic rod 7,
Even if there is a lateral inclination with respect to the running direction of the device 20, the tip ends of all the brushes 1a to 1c over the entire length are reliably pressed against the grass surface.

Instead of being attached to a power unit as described above, the brushing device of the present invention can also be detachably attached to, for example, various types of traveling or self-propelled bunker leveling machines, lawn mowers, etc. via an appropriate connection means. It goes without saying that you can. Furthermore, in the embodiment shown in FIG. 2, one of the substrates 2a of the brush device has a stepped bottom surface in order to mount brushes of different lengths, but the shape of the substrate is not limited to this. do not have.

Furthermore, the brushing device of the present invention can also be used for turf topping work as described above.

[Effect of idea]

As mentioned above, in the present invention, by making one base plate rotatable relative to the other base plate, all the brush tips can be kept in pressure contact with the grass surface as it undulates in the vertical direction. In addition, by movably connecting the rod and the telescopic rod, the tips of the brushes over the entire length of the brush can be reliably pressed against the grass surface even if there is an inclination to the left or right with respect to the running direction of the device. Therefore, brushing work on the grass surface can be performed uniformly and accurately.

In addition, since the brush is removable from the board, when the brush wears out, it can be used for a long period of time by replacing only the brush. It is.
