Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trench device for improving drainage performance of a golf course on an underground surface where drainage is poor, and a structure of the drain trench.

[0002]

2. Description of the Related Art In golf courses such as fairways and roughs, where drainage is poor, water pools may form a hindrance to play, and excessive moisture causes problems such as grass root rot disease. To do. Therefore, for example, Japanese Patent Laid-Open No. 2-1424
As disclosed in Japanese Patent Publication No. 18, a means for forming a drainage ditch of the underdrain is implemented in order to let the infiltrated water flow out in the basement where the drainage is poor.
The method of burying a drainage pipe and a pipe in the place of 50 cm is adopted. However, apart from the new golf course, at the existing golf course, it is difficult to construct a drainage channel of the underdrain with a drain pipe or pipe, which is a difficult task, and it is difficult to dig up the grass surface and roughen the ground. However, once the pipes or pipes are buried, it has a drawback that when the position of the drainage groove is changed next time, it becomes an obstacle and involves a troublesome work such as digging up again and removing it.

[0003] On the other hand, as a means for promoting drainage in the field as well, for example, as in Japanese Patent Publication No. 58-52051 and Japanese Patent Publication No. 59-28695, a bullet is carved in the ground to make a hole, and the rice husk is placed there. However, since this is relatively soft and is intended for the fields to be cultivated later, it has a weak ground breaking force. Therefore, even if you try to use this on a golf course that contains hard soil, the cutting blade will rise, and it will be a groove shallower than the predetermined depth and the drainage groove can not be tilted well,
It causes a problem that drainage does not work well. In addition, if the cutting blade is simply pulled, the cutting blade does not rotate well and the surface is dragged, which damages the surrounding grass and puts a heavy load on the towing vehicle.
Further, if the filling material to be added is rice husks, the filling material will be decomposed on the way, and the filling effect of the pores will not be achieved.

[0004]

SUMMARY OF THE INVENTION The present invention has been made based on the above-mentioned circumstances, and avoids the use of a conventional drainage groove made of pipes or pipes for a place with poor drainage on a fairway, a rough, etc. on a golf course. In order to simplify the work by applying the underdrain drainage method used in the fields, it does not damage the grass surface of the golf course, and the drainage ditch once collapsed or clogged. This is an attempt to improve the drainage function constantly without causing such problems.

[0006]

[Operation] A tow truck is run to a place with poor drainage on the golf course, and first, the cylinder of the three-point link mechanism is operated to lower the lower link and the top link, and the shear blade and the trench groove of the trench device are soiled. Let it sink. Then, the driving motor is started to rotate the rotary shaft, and the drive gear attached to the rotary motor is interlocked with the driven gear via the transmission belt to rotate the coaxial shear blade. Cuts the roots of the grass on the ground surface and cuts the lumps of soil in the direction of travel with a shearing force so as not to damage the grass and reduce the load associated with traction. Then, the trench groove and the trench body following this form a drainage trench at a certain depth in the soil, and further there
From a filling case with two types of fillers, pebbles and sand
Pumice, such as pumice, is dropped and sand is filled on it. When rainwater etc. penetrates there, it quickly flows through the voids of the pebbles, exerting a drainage function, and when a sand layer is formed on the top of the pebbles, the infiltrated water containing muddy water is filtered and fine particles are spilled inside the pebbles. Protect the holes. Therefore, the pores inside the pebbles exhibit water retention and provide water supply during drying. Moreover, since the pebbles have a certain physical strength, the groove will not collapse even if the player steps on it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 is a burutozaa which acts as a towing vehicle, and has a three-point link mechanism 3 in which a pair of lower left and right lower links 6a and 6b are arranged in the rear part and a top link 4 is arranged in the upper part. It connects with a point link mechanism and pulls the trench device 10 mentioned later, and runs. To protect the grass on the ground surface, a protector-2 having a wide width and an elastic body such as rubber adhered to have a constant thickness is worn on the caterpillar of the burutoza-1.

Numeral 10 is a trench device pulled by the bruthezer-1, which is first connected to the three-point link mechanism.
The main rod 11 is arranged in the center, and the cylinder 7
Lower arms 6 suspended from lifting arms 8a and 8b connected to a and 7b and lifting rods 9a and 9b connected to them.
In order to rotatably connect to a and 6b, a shaft rod is passed to a bifurcated branch piece, and arm rods 12a and 12b for pivotally attaching the tips of the lower links 6a and 6b are extended there. Further, in the center of the main rod 11, a top rod 3 having a hydraulic cylinder is extendedly provided with a neck rod 13 pivotally attached. That is, the expansion and contraction of the cylinders 7a and 7b of the lower links 6a and 6b causes the main rod 1 to move.
1 is moved up and down, the main rod 11 is rotated by the expanding and contracting action of the cylinder 5 of the top link 4, and the whole trench device is inserted into the ground, and the starting force is taken out.

Then, at the left and right end portions of the main rod 11, at a position substantially in the center behind the caterpillar of the bult-the-1,
A pair of left and right support rods 14a and 14b are provided, and vertical rods 15a and 15b are vertically provided toward the ground surface. The vertical rod 15
a and 15b are supporting rods 14 in order to enable depth adjustment.
Bolt holes are formed in a and 14b so that the position can be freely changed in the vertical direction stepwise. Then, shear blades 16a and 16b for cutting the turf surface and the ground surface to provide a rearward path are axially attached to the ends of the vertical rods 15a and 15b.
It is desirable that a and 16b be formed with a wave on the periphery to promote the discharge of soil.

Then, in order to promote the forced rotation of the shearing blades 16a, 16b, first, bearings 17a, 17b are arranged on the support rods 14a, 14b, and a rotary shaft 18 is mounted between them. At this time, the bearings 17a and 17b have the shear blade 16
In order to correspond to the vertical movement of a and 16b, bolt holes are bored in the main rod 11 and the bearings 17a and 17b at the three stages of front, middle, and rear so that the bearings 17a and 17b can be moved in the front-rear direction. . Then, the gear 19 is fixed to the rotary shaft 18, while the steering is extended to the main rod 7, and the driving motor-2
0 is attached, the driving motor 20 and the gear 19 are meshed with each other, and the rotation shaft 18 is rotated by the start of the driving motor 20. At this time, the driving motor 20 may be either a hydraulic motor or an electric motor, but the rotation direction can be changed forward and backward, and the rotation directions of the shear blades 16a and 16b can be changed. Is desirable.

Next, a rotary shaft 18 pivotally mounted on the main rod 11.
The drive gears 21a and 21b are axially attached to the sides of the support rods 14a and 14b at the left and right ends of the blades, while the shear blades 16a and 16b are attached.
The driven gears 22a and 22b are coaxially mounted on the driven gears 21a and 21b. Then, the drive gear 21
a, 21b and driven gears 22a, 22b are hung on transmission chains 23a, 23b or belts, the driven gears 22a, 22b are rotated in accordance with the rotation of the rotary shaft 18, and the shear blade 16a axially attached thereto. , 16b can be rotated. At that time, when the shear blades 16a and 16b are moved up and down, the chains 23a and 23b cannot follow, so when the shear blades 16a and 16b are divided into upper, middle, and lower, for example, front, middle, and rear. The bearings 17a and 17b in which the positions of the bolt holes are set in three stages are moved in correspondence with each other so that they can be mutually adjusted.

Next, the back rods 24a, 2 are provided behind the main rod 11.
4b, and trench grooves 25a, 2 for dividing soil there
5b is inserted, and the attachment is made by drilling bolt holes in the back rods 24a, 24b, and also by gradually drilling bolt holes in the trench grooves 25a, 25b, and moving up and down by screwing bolt nuts. And The trench grooves 25a and 25b are sharpened so that the soil can be easily torn, and connect the trench bodies 26a and 26b of a circle, ellipse, hexagon or the like according to the shape and size of the trench to be formed at the tip.

Further, behind the main rod 11, the left and right back rods 24 are provided.
Mounting rods 27a and 27b are extended in the middle of a and 24b, and wheels 28a and 28b for keeping the main rod 11 and the entire apparatus 10 attached thereto at a constant height above the ground surface are extended below the attachment rods 27a and 27b. That is, the wheels 28a that rotate in contact with the ground surface,
28b keeps the main rod 11 at a constant height and, as a result, keeps the entire device from sinking too much into the ground.

Finally, 29 is a filling case, and at least a small stone such as pumice is filled in a container body having a constant volume so that the sand can be divided and stored separately if necessary, and the lower end thereof can be stored. In addition, the drop ports 30a, 30b and 31a, 31b are provided so that they can be dropped into the trench.

The operation of this embodiment will be described. First, a wetland or a poorly dry portion is specified on a lawn surface such as a fairway on a golf course, and the burutoza-1 is moved there. Then, the cylinders 7a, 7b of the lower links 6a, 6b of the three-point link mechanism 3 of the burutoza-1 are extended to lower the arm rods 12a, 12b connected to the pulling rods 9a, 9b, and the cylinders. -5 is extended, the neck rod 13 connected to the top link 4 is lowered, and the trench device 10 is lowered. Then, at the same time as the descent, the burutoza-1 is run slowly. At the same time, the driving motor 20 is started and the shaft gear 1
9 is rotated, and the rotation of the rotary shaft 18 drives the drive gears 21a and 21b axially mounted on the rotary shaft 18. Then, the driven gears 22a, 2a are transmitted through the transmission of the chains 23a, 23b.
2b is rotated, and the shearing blades 16a and 16b are rotated accordingly, pressed against the ground, and moved forward. Then, the shear blades 16a, 16 that are forcibly rotated
b cuts the grass surface with roots and it is about 30-5 in the ground.
The ground can be reliably torn to about 0 cm, and therefore, the shear blades 16a and 16b can be inserted to a predetermined depth in the ground to open a part of the closed skin. At this time, since the shear blades 16a and 16b rotate and cut the grass roots on the ground surface, they do not drag and do not damage the grass roots. In addition, since the shearing force of the rotary blade acts on the clod,
The towing vehicle 1 does not forcibly drag the shear blade to collide with the earth mass, and the load on the towing vehicle can be significantly reduced.

At this time, in the case of ordinary soil, the shearing blade 1
The rotation directions of 6a and 16b are forwardly rotated in the forward direction. However, when they hit a hard layer called subsoil, it is preferable to rotate them in the reverse direction to expel the cut soil upward. That is, the golf course fills the depressions or cuts the slope to set the slope, but when a hard soil layer called subsoil appears on the cut slope. However, in order to remove the hard soil and make it easier to cut, the shearing blades 16a and 16b are rotated in the reverse direction, not in the normal direction.

Next, the trench blades 25a and 25b arranged after the shear blades 16a and 16b follow the shear blades 16a and 16b.
On the ground where b is cut open, the trench bodies 26a and 26b remove the soil and form a trench. The groove has a shape and cross-sectional area suitable for drainage, and has a relatively large cross-sectional area such as a circular shape or an elliptical shape where water is likely to collect, and is usually about 5 to 10 cmφ.

Next, in the groove where the drainage groove a is formed,
The inputs 30a and 30b of the filling case 29 are opened, and a continuous porous small stone b such as pumice having a diameter of 3 to 7 mmφ is dropped from there. This porous small stone b has a large number of communicating pores inside, and the pores have water permeability and, at the same time, exhibit water retention. Furthermore,
After the porous pebbles b have been charged, the charging port 29 for the filling case 29
1a and 31b are opened, and sand is dropped from there, and the pebbles b
The top of the drainage groove a is covered with sand c over it, or the face is exposed to the top surface of the ground surface. As a result, if there is precipitation in the golf course, the water accumulates on the depression surface, and if a drainage groove a is formed in the vicinity, water will permeate underground from there, or the face will appear on the crown surface. Penetrates through the sand. When the permeated water enters the drainage channel a, first, the pebbles b
Since the gap holes in the pebbles b are communicating holes, water flows through the gaps, flows down along the slope, and is drained toward the drainage basin. At this time, if the sand c is filled in the upper part or in the vertical path, it is filtered before entering the drainage a filled with the pebbles b, mud and dust are removed, and water with no mixture enters the drainage ditch. Be flowed in. Therefore,
The pebbles b exhibiting water permeability prevent the holes from being blocked by mud or small dust on the way and lose the water permeability. Therefore, good drainage can be maintained regardless of the time. In addition, when the pebble b is dried in the summer, water is stored in the pores of the pebbles b and exhibits water retention. That is, the pores of the pebbles b retain water permeability when they are full of water, but when they are dry, they trap water in the voids, so they serve as a water supply source and provide water to the surrounding soil and grass roots that lack water. And solve the problem of withering and yellowing.

When the trench is finished at a predetermined position, the burto-the-1 is retracted, and the portion where the trench is dug is stepped on with the caterpillar on which the protector 2 is worn to restore the cut ground. Press in the direction.

[0020]

The working machine of the present invention relating to the above-mentioned construction and operation does not require piping or the like at a predetermined position on the golf course, and can construct a drainage groove by cutting and digging the ground, so that a large amount of work can be performed. It has an excellent effect that it can be simplified. At that time, by forcibly rotating the shear blade, the soil mass can be sheared without damaging the roots of the lawn, and the generation of load due to traction can be reduced, and even if there is a hard soil layer of the cut soil. Since the groove can be formed with an accurate inclination, drainage can be efficiently performed. Further, if the drainage gutter is filled with small stones having water permeability and water retention, the shape of the drainage gutter is first retained by the strength of the stone, and there is a risk that it will be crushed even when stepped on by a player or the like. It is a very advantageous invention that can provide balanced water supply and drainage that does not exist, and drains when full, and exerts a water supply action when drying, which can promote the growth of turf and protect from pests.
