DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for rubbing green soil into a green hole drilled by a drilling machine in order to improve lawn rooting at a golf course (green). .

[0002]

2. Description of the Related Art Conventionally, in order to improve grass rooting at a golf course (green), a perforated pipe is periodically inserted into the ground with a green perforator to remove soil that has entered the perforated pipe, thereby opening the ground. The holes are filled with fertilizer and fresh soil.
There are three known methods for putting the new soil, such as a method in which sand is scattered on the green and the brush is simply pulled, a method in which the brush is reciprocated right and left, and a method in which the brush is rotated.

[0003]

As described above, when the brush is simply pulled, the diameter is 7 to 16 mm and the depth is 7 to 16 mm.
The drawback is that it takes a lot of work to get enough sand into the 8-cm hole.
When the brush is reciprocated left and right, when the brush is moved to the left and right ends, there is a drawback that the dead point of movement occurs and the sand is moved to the left and right, so that the sand does not enter the hole enough. There was a drawback that the thing to be rotated would blow sand by centrifugal force before putting it in the hole. The present invention has been developed to solve those difficulties.

[0004]

The present invention employs the following technical means to solve the above-mentioned problems.

That is, a brush of a green earth rubbing machine having a horizontally long brush that slides on the ground under the machine base is supported by a plurality of vertical support shafts in the horizontal direction, and the support shafts are mounted on the machine base. A green that moves the earth rubbing machine in the direction perpendicular to the horizontally long brush while rotating both ends of the brush so as to draw a perfect circular locus by rotating the drive shaft vertically suspended on the brush arm through a crank arm. It is composed of a dressing method and a green dressing device. The green earth rubbing device is one in which the machine is towed by a towing vehicle or the like, and a motor is mounted on the machine. A drive shaft rotated by the prime mover is suspended from the machine base, and a support shaft is eccentrically rotatably disposed on the drive shaft via a crank arm. A plurality of the support shafts are fixed on the frame of the horizontally long brush along the longitudinal direction.

[0006]

According to the present invention constructed as described above, the following operations are provided. That is, the green earth rubbing device is one in which the machine base is towed by a towing vehicle or the like, and when the prime mover is driven, the drive shaft is rotated, and the support shaft provided on the drive shaft via the crank arm is rotated. It rotates around the drive shaft. Since a plurality of the support shafts are fixed on the frame of the horizontal brush along the longitudinal direction, the horizontal brush remains horizontally long in the traveling direction, and the both sides of the horizontal brush are offset by the eccentric distance between the drive shaft and the support shaft. Since the ends rotate while drawing a circular locus, the sand rubs into the holes without changing the direction of the horizontally long brush. Since the machine frame is towed by a towing vehicle or the like, the horizontal brush moves forward while rubbing sand into the hole without changing the direction. In particular, the brush moves forward without changing its direction, but by rotating the support shaft around the drive shaft, the brush always retreats regularly. Has the effect of putting.

[0007]

Embodiments of the present invention will be described with reference to the drawings. 1 is a side view and FIG. 2 is a plan view. The green rubbing device 1 is a wheel 2 that can be adjusted in height.
The drive mechanism 4 is mounted on the machine base 3 provided with the drive mechanism 3, and drive shafts 5, 5 driven by the drive mechanism 4 are vertically provided below the machine base 3. Support shafts 7, 7 are eccentrically suspended below the drive shafts 5, 5 via crank arms 6, 6, and lower ends of the support shafts 7, 7 extend along the length of the horizontally long brush 8. The array has been fixed. The machine base 3 is connected to a towing vehicle 11 by a connecting member 9 and is towed. The drive system of the green earth rubbing device 1 will be described with reference to FIG. The machine base 3 is formed in a horizontally long box shape, and a plurality (two in the figure) is formed along the length.
Are disposed, and the drive shafts 5 and 3B are provided respectively.
5 are mounted vertically. Crank arms 6 and 6 are attached to the lower ends of the respective drive shafts 5 and 5.
The support shafts 7, 7 are eccentrically suspended through bearings 7A, 7A in an eccentric manner within a range of (not limited to) centimeters. Pulleys 5A, 5A are fixed to the upper portions of the respective crank arms 6, 6, and a V
A belt 5B is erected. The one drive shaft 5 is connected to a speed reducer 4A of the drive mechanism 4. A hydraulic hose 10A of a hydraulic machine 10 is connected to the drive mechanism 4. The drive system is of a hydraulic type, but may be an electric motor, a gasoline engine or the like. The lower ends of the shafts 7, 7 are fixed to the upper part of the frame 8A of the brush 8. If the density of the bristles of the brush 8 is rough at the front part in the advancing direction and dense at the rear part, the sand on the green can be taken into the brush without being pushed by the brush, and the sand can be efficiently rubbed into the holes. The horizontal length of the brush 8 can be appropriately set, for example, a plurality of brushes having a length of 60 cm are arranged in series, or a brush having a length of 180 cm is used. Also, a plurality of brushes 8 can be arranged before and after the machine base 3. In this case, the length of the brush 8 can be not only orthogonal to the traveling direction of the machine base 3 but also oblique. 1 can be adjusted in height by a finishing brush.

In the present invention configured as described above, the following functions and effects are obtained. After piercing the green, sand is scattered on the green. If the sand is wet, leave it to dry, and if dry sand is scattered, you can work immediately. When the height of the wheel 2 and the finishing brush is adjusted according to the state of the green, the pressure of the rubbing brush 8 on the green can be adjusted. Subsequently, the towing vehicle 1 is rotated while the drive shafts 5 and 5 are rotated.
When the brush 1 is started, the direction of the brush 8 does not change in the lateral direction with respect to the traveling direction, and the longitudinal ends P1, P2 of the brush 8 are connected to the drive shafts 5, 5 and the support shafts 7, 5 as shown in FIG. Circle locus Q whose radius is the eccentricity difference of 7 (10 to 20 mm)
1 and Q2. At the same time, the center point P of the brush 8
3 also draws a perfect circle locus Q3. This rotation speed is 5
Assuming that the forward speed of the towing vehicle is 5 km / h (1.4 m / s), the speed is approximately 28 times / sec, as shown in FIG.
One revolution per centimeter of forward movement means that the locus Q2 of the side end P2 of the brush reciprocates left and right by the length of the eccentricity difference (10 to 20 mm).
It will have a left and right amplitude of 0 mm. That is, in FIG. 5, both the right inclined sand m1 pushed by the brush 8 moving forward while swinging to the right and the front sand Mm pushed by the advance are rubbed into the hole H1. In the next hole H2, both the mixed flow sand m2 pushed by the brush 8 moving forward while swinging to the left and the preceding sand Mm pushed by the advance are rubbed. In the third hole H3, the left and right slanted sand m2, the right and left slanted sand m1 are rubbed. As described above, the brush 8 performs the steps of shifting the sand to the left, right, and pre-press the hole by one rotation of the support shafts 7, 7 and rubs the hole, so that the hole can be filled efficiently. That is, as can be clearly understood from FIG. 4, even when the center line L of the brush 8 and the drive shaft 5 are moving forward, the center line L
Is always returning to the rear of the drive shaft 5, which means that the sand that is pushing forward is once returned to a free state from the brush, and then pushed forward (to the oblique direction) again. It will push in the direction of the hole in a well-balanced manner.

[0009]

The present invention configured as described above has the following excellent effects.

A. In the green rubbing device, a plurality of support shafts are eccentrically mounted on a plurality of drive shafts via a crank arm, and each support shaft is arranged in a longitudinal direction of the horizontally long brush. Rotation, the horizontal brush does not change the directionality of the horizontal direction to the traveling direction, and draws a round circle with the eccentric difference between the drive shaft and the support shaft at both ends of the longitudinal brush, Thus, there is an effect that the sand in the left-right direction can be pushed into the hole and the hole can be reliably closed.

B. While the green mesh rubbing device is in progress, even if the drive shaft is moving at a constant speed, the center of the brush always returns to the back of the center of the drive shaft while drawing a perfect circular locus. The sand pushed forward is stirred in a small circular locus, and the brush bristles return to the back. Since it is pushed, the sand is moved in a well-balanced manner, and there is an effect that the amount of sand entering the hole is rubbed without much unevenness.

C. The small difference in eccentricity of the shaft of the brush with respect to the drive shaft can increase the number of rotations of the shaft, which can increase the number of times the brush moves within a certain forward distance, and reduce the amount of sand around the hole. Can be rubbed into the hole as quickly as a spiral.

D. Since the difference in eccentricity of the support shaft with respect to the drive shaft is small, a rubbing effect such as a vibration can be obtained even around the root of grass.

E. Since the structure is simple, the manufacturing cost can be reduced. In particular, since the hydraulic pressure of the towing vehicle or the like can be used, there is an effect that the entire structure of the green earth rubbing device can be simplified.
