Description

  The present invention relates to a rubbing device for rubbing mesh sand sprayed on turf such as a golf course, and a rubbing work machine provided with the rubbing device.

  Generally, grass as a sports turf can be frayed and damaged beyond recovery by being exposed to intense treading pressure. In particular, in a region where the treading pressure of a golf course is frequently applied, the lawn tends to be shortened even if it is not worn out, and there is a case where the growth and recovery after being stepped on are not sufficient. Therefore, in addition to lawn aeration work, an appropriate amount of eye sand is sprayed.

  For example, Patent Document 1 proposes a mat-type dust sand rubbing machine in which a vehicle is provided with a dust sand rubbing mat that is detachable via a support device. . Examples of the mesh sand rubbing mat include metal nets, rubber mats, and brush mats. However, when the mat sand rubbing operation is performed using such a mat type rubbing apparatus, it is difficult to evenly sand the sand sand, and there is a problem that skill is required for the rubbing operation.

On the other hand, a brush-type rubbing work machine is also proposed in which a brush for rubbing sand is provided on the frame of the traveling machine body so as to be movable up and down (see, for example, Patent Document 2). When the brush-type rubbing work machine is used, it is easier to rub the sand evenly than the mat-type work machine, and the work is simplified.
Japanese Patent Laid-Open No. 9-37605 JP 2000-116204 A

  However, when the brush-type rubbing work machine is used, the following problems occur. The first problem is that the sand seems to have been rubbed in evenly, but when viewed over a wider area, the part that originally had a lot of eye sand was more, but the part that had less eye sand was a little rubbed. End up. In such a rubbed green, the golf ball heading for the hole cup rolls while swinging up and down, left and right in front of the hole cup, and the technique of each golfer cannot be sufficiently reflected in a golf game.

  As a second problem, since the brush gradually wears, it is necessary to monitor the wear state and adjust the ground contact height of the brush. For example, if the brush wears out and the rubbing operation is performed from the first hole to the last hole without adjusting the ground contact height, the rubbing state is different between the first hole and the last hole. .

  As a third problem, when a brush-type rubbing work machine is used on a green with a large undulation or a green with a steep slope, the resistance by the brush increases when climbing a portion with a large slope. As a result, the wheels of the rubbing work machine will slip and not be able to work, and slip marks will remain on the green, causing damage to the lawn.

  Therefore, in view of the above-mentioned problems of the prior art, the present invention can evenly rub the sand over a wide area, does not require adjustment work even for a long time, and at the same time has a large undulation and steep slopes. It is an object of the present invention to provide a rubbing apparatus and a rubbing work machine that can prevent the work machine from slipping even with green.

In order to achieve the above object, the following technical measures were taken.
That is, the rubbing device of the present invention includes a frame body that can be mounted on a work machine body, and a rubbing member provided on the frame body, and the rubbing member is brought into contact with the granular material dispersed on the ground. In the rubbing device for rubbing the granular material, the rubbing member includes a leveling bottom portion having a lower surface facing the ground in the rubbing operation state and having a long lower surface in a direction substantially perpendicular to the working direction, and both longitudinal ends of the lower surface in the rubbing operation state. It has a leveling wall portion having a wall surface extending upward from the front side edge in the working direction of the lower surface across the portions.

  If the rubbing device of the present invention is used for rubbing work, the rubbing member has a leveling bottom portion having a lower surface that is long in a direction facing the ground and substantially perpendicular to the traveling direction, and the lower surface between both longitudinal ends of the lower surface. It has a leveling wall part with a wall surface extending upward from the front edge of the running direction, and it is not a soft brush type as in the past, but it is leveled by the `` surface '' consisting of the wall surface and the bottom surface, so the thickness of It is possible to reliably remove a certain part of the sand and to place the sand in a thin part of the sand. Therefore, there is no blur in the rubbing state in a wide range, and the sand can be evenly rubbed in the wide range.

Further, since the contact is made on the surface, there is little problem of wear like the brush type, and it is not necessary to monitor the wear state and adjust the ground contact height.
Furthermore, since the surface is slid on the lawn, the resistance at that time is smaller than that of the brush type. Therefore, when the rubbing device is used with a green with a large undulation or a green with a steep slope, the resistance is smaller than with a brush type when the part with a large slope is climbed. Thereby, the wheel of the rubbing work machine equipped with the rubbing device does not slip.

  As a structure of the rubbing member, for example, the leveling bottom portion and the leveling wall portion are both formed in a plate shape that is long in a direction substantially orthogonal to the working direction, and have a substantially L-shaped cross section. By making the rubbing member substantially L-shaped in cross section, it can be easily manufactured and the weight can be reduced.

  It is preferable that the rubbing member is swingably provided on the frame body. If the rubbing member is swingable, when there is a change in topography, the rubbing member can follow the topography change without moving the frame body.

  The rubbing member is preferably provided in a plurality of rows along the working direction. For example, even if there is a portion where the mesh sand is thick, it can be rubbed a plurality of times in a single run, and work efficiency can be improved.

  The rubbing work machine of the present invention includes a work machine body, and a rubbing device that is mounted on the work machine body so as to be movable up and down and rubs the granular material dispersed on the ground. This is a rubbing apparatus.

  Since the rubbing apparatus according to the present invention is equipped with the rubbing device according to the present invention, when rubbing work is performed with the rubbing work machine, it is possible to rub the sand evenly over a wide area, It is not necessary to monitor the wear state and adjust the ground contact height of the rubbing member, and even if the ascending portion is climbed, the wheel does not slip.

  As described above, according to the present invention, the rubbing member is between the leveling bottom portion having a lower surface that faces the ground in the working state and has a long lower surface in a direction substantially orthogonal to the working direction, and the longitudinal ends of the lower surface in the working state. It has a leveling wall part with a wall surface extending upward from the work front side edge of the lower surface, and is not a soft brush type as in the past, but is leveled by a "surface" consisting of the wall surface and the lower surface As a result, it is possible to rub the sand evenly over a wide area, and no adjustment work is required even for a long period of time, and at the same time, it prevents the rubbed work machine from slipping even on greens with large undulations and steeply inclined greens. Can do.

Thus, the first and second rubbing members 2A and 2B are particularly swingable in the vertical direction. Therefore, when the rubbing device 17 is not in the grounded state, the first and second rubbing members 2A and 2B are slightly lowered downward, and if the rubbing device 17 is in the grounded state, the first and second rubbing devices 17 The rubbing members 2A and 2B are pushed up in contact with the ground. As described above, the first and second rubbing members 2A and 2B are particularly swingable in the vertical direction, so that it is possible to follow changes in topography and changes in the amount of sand.

  When rubbing the sand spread on the lawn with the rubbing work machine 1 of the present embodiment, the coarse sand is smoothed by the large-diameter roller 21, and the fine sand of the fine sand is smoothed by the small-diameter roller 24 on the front side. Next, the sand is uniformly rubbed by the first and second rub members 2A and 2B. The rear small diameter roller 24 is a spare roller. Thus, since the first and second rubbing members 2A and 2B are arranged in two rows along the working direction, even if there is a portion where the mesh sand is thick, rubbing multiple times in one run. Work efficiency can be improved.

  If the rubbing work machine 1 to which the rubbing device 17 of the present embodiment is mounted is used for rubbing work, the first and second rubbing members 2A and 2B are long in a direction facing the ground and substantially perpendicular to the traveling direction. A leveling bottom portion 35 having a lower surface 34, and a leveling wall portion 37 having a wall surface 36 extending upward from a work direction front edge 34 a of the lower surface 34 across both longitudinal ends of the lower surface 34. It is not a soft brush type, but it is leveled by the “surface” made up of the wall surface 36 and the lower surface 34. Therefore, the thick mesh sand portion is surely removed, and the mesh sand is surely placed in the thin mesh sand portion or the depression. be able to. Therefore, there is no blur in the rubbing state in a wide range, and the sand can be evenly rubbed in the wide range.

  In addition, since the contact is made on the surface, there is no wear that was a problem with the brush type, and there is no need to monitor the wear state and adjust the ground contact height. Furthermore, since the surface is slid on the lawn, the resistance at that time is smaller than that of the brush type. Therefore, when the rubbing device 17 is used with a green with a large undulation or a green with a steep slope, the resistance becomes smaller than that with the brush type when the part with a large slope is climbed. Thereby, the wheel of the rubbing work machine 1 equipped with the rubbing device 17 does not slip.

  In the present embodiment, the rubbing members 2A and 2B have a substantially L-shaped cross section, so that they can be easily manufactured and the weight can be reduced. Further, since the first and second rubbing members 2A and 2B are swingably provided on the frame body 22, the rubbing members 2A and 2B can be moved without moving the frame body 22 when there is a change in topography. Can follow the terrain change.
