Description

  The present invention relates to a method for trimming a planting zone planted on a road side end or the like, and a hedge trimmer fitting used in this trimming method.

  There is a place where the planting belt is continuously vegetated at the end of the road, and it is necessary to trim (cut) the shape of such a planting belt at least once a year. A large dedicated machine may be used for this cutting, but most landscaping companies do not have such equipment. Therefore, the actual situation is that the reciprocating type hedge trimmer with a clipper blade is used for manual trimming (the rotary type is not usually used because it is dangerous to bounce off objects) ).

  Since the planting belt is trimmed so that the cross section becomes a square, the hedge trimmer must be operated on at least three sides of the top and both sides. Since this hedge trimmer is an engine-integrated type and heavy in weight, it is very laborious to operate it over a long section and in the same state on three sides. In particular, this cutting is often carried out around May, before the flower buds are attached to the trees, so the heat is added and the physical wear is very difficult. In addition, there is also a thing which made the engine a backpack type, but the back is heated by the engine, and this becomes severe again.

  Therefore, the present invention uses a power shovel owned by any ordinary landscaping company, attaches a hedge trimmer to this using a dedicated mounting tool, and effectively utilizes the characteristics of the power shovel to ensure safety. It is intended to make efficient and clean trimming.

  Under the above-described problems, the present invention provides a planting zone according to claim 1, wherein the planting zone is trimmed by a reciprocating hedge trimmer from which a clipper blade driven by an engine protrudes from the main body so that the cross section becomes a square. In the trimming method, the body part of the hedge trimmer is positioned on the side of the bucket of the excavator, and the clipper blade is positioned beyond the top and bottom surfaces of the bucket both when the clipper blade extends on the top surface side and the bottom surface side. In this way, the main body is located at a position outside the top surface and both side surfaces of the tree planting belt, and only the clipper blade is mounted along the top surface and both side surfaces of the tree planting belt. Adjust the angle of the arm and bucket of the excavator and the excavator, keep this state, and run the excavator in parallel with the planting zone so that the cross section is the same Trimming method of planting zone, characterized in that uniform cutting is obtained by providing a.

  And this invention is the attachment tool of the hedge trimmer which attaches the hedge trimmer used for the cutting method of the above-mentioned planting zone described in Claim 4 to the side surface of the bucket of a power shovel, and this attachment device is the side surface of the bucket. A mounting plate that is fixed to the arm, an arm that extends upward or downward along the side of the bucket from the mounting plate, and is attached to the arm either forward or backward, and a clip trimmer blade of the hedge trimmer is attached to the top and bottom surfaces of the bucket. Provided is a hedge trimmer fitting for use in a method for trimming a tree-planting band, characterized in that it comprises a base that holds and supports the main body portion at a position exceeding the position.

  According to the present invention, the hedge trimmer can be held by a power shovel and the trimming work can be performed, so the work is easy and efficient, the cost can be reduced, and the operator is located away from the clipper blade, It is also safe. Further, since the operator does not have to hold the hedge trimmer by hand, the worker is free from vibration and noise and does not inhale exhaust gas. In addition, since the posture of the hedge trimmer does not change during the trimming operation, the cross section of the planting zone is the same in the longitudinal direction, and a very clean trimming is possible. By the way, this is impossible by simply holding the hedge trimmer with a power shovel, and it was possible only by devising a dedicated fixture and effectively utilizing the characteristics of the power shovel. It is.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view showing a state in which a hedge trimmer is attached to a side surface of a bucket by an attachment, and FIG. 2 is a plan view. However, the hedge trimmer A used in the present invention may be a general-purpose type. That is, the hedge trimmer A is a reciprocating type in which the clipper blade 2 protrudes from the main body 1 and the clipper blade 2 is reciprocated by the engine 3 placed on the main body 1. Since the drive structure is well known, detailed description is omitted here, but the main point is that the crank is rotated by the output shaft of the engine 3 and the clipper blade 2 is connected to the crank (not shown).

  In this case, the clipper blades 2 include a double-blade type and a single-sided type. However, the present invention uses cutting in both the forward and reverse directions. A double-edged type is suitable. In addition, the hedge trimmer A has two handles 4a and 4b that can be held by an operator by hand, one extending from the front of the main body 1 and the other from the rear.

  In the present invention, the hedge trimmer A is attached to the side surface of the bucket 6 of the excavator B by the fixture 5. The fixture 5 in this example has a mounting plate 7 fixed to the side surface of the bucket 6 with a bolt or the like, and a boss 8a formed at one end of a shaft body 7a protruding from the mounting plate 7 toward the side surface. The arm 8 is fixed with bolts 9 and extends upward or downward along the side surface of the bucket 6 (by rotating the boss 8a with respect to the shaft 7a), and the boss 8b formed at the other end of the arm 8 has a shaft. The body 10a is inserted and fixed with a bolt 11 or the like, and includes a base 10 that fixes and supports the main body 1 of the hedge trimmer A.

  In this case, the shaft body 10a of the base 10 is provided on both sides of the bottom plate 10b of the base 10, and can be attached to the arm 8 either forward or backward by changing this. Further, in order to fix the main body 1 of the hedge trimmer A to the base 10, the presser body 12 capable of pressing an appropriate position of the main body 1 with a bolt or the like is fixed on the bottom plate 10 b with a bolt or the like. . Further, when the hedge trimmer A is attached to the bottom surface or the top surface of the bucket 6 with the fixture 5 as described above, the length of the arm 8 is such that the clipper blade 2 protrudes beyond the bottom and top surfaces of the bucket 6. Etc. have been adjusted. This is because the clipper blade 2 can be used without being obstructed by the bucket 6.

  Thereby, the hedge trimmer A is attached with the clipper blade 2 facing the front or the rear of the bucket 6 by changing the extending direction of the arm 8 with respect to the mounting plate 7 and the mounting side of the base 10 with respect to the arm 8. Moreover, the clipper blade 2 is attached in such a manner that it exists on the bottom surface side and the top surface side of the bucket 6. In any case, the clipper blade 2 is set to be positioned beyond the bottom surface and top surface of the bucket 6 (when the clipper blade 2 is positioned on the top surface side of the bucket 6, the bottom surface thereof is set. Is usually set to face upward).

  In addition, in the present example, the angle of the arm 8 with respect to the mounting plate 7 and the angle of the base 10 with respect to the arm 8 can be arbitrarily changed by tightening bolts 9 and 11 respectively. The bucket 6 of the power shovel cannot turn 360 ° due to the dead angle due to the arm (boom) or link structure, and thus the clipper blade 2 is directed to any angle in this way.

  Further, the gas spring 13 is interposed between the main body 1 and the clipper blade 2 in this example. That is, the gas spring 13 is passed over the main body 1 and the cover 1 a covering the base portion of the clipper blade 2 protruding from the main body 1. This is to absorb the impact applied to the clipper blade 2, and in particular, the movement of the power shovel has a large impact, so that it is buffered to prevent the clipper blade 2 from being broken.

  Next, a case where the hedge trimmer A is attached to the bucket 6 of the excavator B and the planting zone 14 is trimmed will be described. Although it has been described above that the cross section of the tree-planting zone 14 is trimmed so as to be a square, this is to facilitate the pruning operation. In other words, holding the hedge trimmer A by hand and moving it along the top and side surfaces for trimming is because holding the hedge trimmer A horizontally or vertically is easier than setting it at another angle. It is.

  However, in terms of the growth and aesthetics of the planting zone 14, it is preferable to use a trapezoid with a narrow upper base. Originally, the tree is narrower as the branches and leaves expand toward the lower side and go upward, so it is naturally preferable that the tree planting zone 14 has a shape corresponding to this. In addition, when such cutting is performed at the planting zone 14 at the end of the road, there is an advantage that the road width can be widened. In particular, children and elderly people walking on the sidewalks on the roadside opposite to the tree planting zone 14 have a low line of sight. However, when it has such a trapezoidal cross section, this feeling of pressure is weakened. However, the reason why the cross section is not trimmed is that when the hedge trimmer A is tilted and used, the tilt angle is not clear, and the trimmed figure is disturbed, and the labor burden on the worker is increased. Because.

  4 to 6 are explanatory diagrams when the hedge trimmer A is attached to the bucket 6 using the fixture 5 according to the present invention, and the cutting work is performed so that the cross section of the planting zone 14 becomes a narrow trapezoid. In this case, FIG. 4 shows a case where the top surface of the tree-planting zone 14 is trimmed. In this case, the clipper blade 2 is attached so as to be positioned on the bottom surface side of the bucket 6, and the angles of the first arm 15, the second arm 16, and the bucket 6 of the excavator B so that the clipper blade 2 is at a predetermined height. Adjust. Of course, at this time, the main body 1 which is an uncut portion needs to be located at a position off the top surface. In this operation, the traveling unit 17 of the excavator B is set parallel to the planting zone 14, and the working unit 18 including the first arm 15 and the like is directed toward the planting zone 14.

  If the above state is set, the first and second arms 15 and 16 and the bucket 6 are fixed in their positions, the hedge trimmer A is driven, and the excavator B is driven along the tree-planting zone 14 for cutting. do. At this time, it is preferable from the safety and efficiency of work to adjust the angles of the first and second arms 15 and 16 so that the excavator B is positioned as close to the tree planting zone 14 as possible.

  At this time, the excavator B must travel in parallel with the planting belt 14, but in order to ensure this, a marker or the like is put out from the excavator B to the planting belt 14 side and traveled using this as a guide. The position will not shift. In this case, the start of the hedge trimmer A and the speed setting thereof are performed by operating the starter, stop button and accelerator lever provided on the hedge trimmer A, and this is extended to the seat of the power shovel B with an appropriate harness or the like. It is convenient because it can be operated remotely.

  When the cutting of the top surface of the tree-planting zone 14 is completed, the cutting of the side surface is performed next (the order is not limited to this). FIG. 5 shows a case where the side of the road side is trimmed, but the angle of the first and second arms 15 and 16 and the bucket 6 is adjusted to the angle of the side while the hedge trimmer A is mounted as described above. . In this case, it is the same as described above that the main body 1 needs to be positioned upward so that the entire side surface can be trimmed.

  By the way, since this side surface is inclined, if the angle is difficult to understand, a model ruler or the like of the cross section is prepared, and the angle of the bucket 6 may be adjusted so that the clipper blade 2 follows this. And it fixes to this state, drives the hedge trimmer A, makes the power shovel B run, and trims this side. This traveling may be forward or backward, and when the clipper blade 2 is of a double-blade type, the backward operation can be performed.

  When the pruning of one side is completed, the pruning of the other side is performed this time. FIG. 6 shows a case where the side surface on the side opposite to the road is trimmed. At this time, the arm 8 of the fixture 5 is rotated by 180 ° so that the clipper blade 2 is positioned on the upper surface side of the bucket 6. (In the previous mounting, even if the arms 15 and 16 are adjusted, the clipper blade 2 does not follow the slope of the planted body 13 on the side opposite to the road, and if this is possible, there is no need to change). And the angle of the 1st and 2nd arms 15 and 16 and the bucket 6 is adjusted, and the clipper blade 2 is united with the angle of this side surface. Thereafter, the pruning operation is performed in the same manner as described above while fixing in this state.

  FIG. 7 is a perspective view showing another example of the fixture, but the fixture 19 of this example is a plate having a U-shaped cross section for mounting and fixing the main body 1 of the hedge trimmer A. is there. That is, the main body 1 of the hedge trimmer A is placed on the bottom plate 19a, and the front and rear portions thereof are firmly fixed to the bottom plate 19a with U bolts 20 or the like, and attached to the bucket 6 on the wall bodies 19b on both sides. A mounting structure 21 is provided. Various attachment structures 21 can be considered, but the simplest one is fastened with bolts or the like. Although the thing of this example cannot change the angle of the hedge trimmer A with respect to the bucket 6, there exists an advantage with a simple structure and cheap manufacturing cost.

  The above is the best mode for carrying out the present invention, but the present invention takes other various modifications. For example, the fixture is not limited to the shape described above. The point is that the hedge trimmer can be attached to the side of the bucket with its front-rear direction changed. Also, the mounting structure is not limited to a hole or a bolt, but may be a lock type using a cam or the like. Furthermore, the attachment may be attached to both sides of the bucket.

  There are various sizes of tree planting zones, and when one side of the planting zone is longer than the length of the clip trimmer blade of the hedge trimmer, one side is divided into a plurality of times. The cross-sectional shape of the tree planting zone is not limited to a trapezoidal shape, but may be a rectangular shape or a polygon such as a pentagon. In this case, the angle can be easily set. If the cross section is trapezoidal, the hedge trimmer does not have to stand up completely when trimming the side surfaces, which is more preferable for the engine posture when supplying fuel or lubricating oil. In addition, the power shovel may be a small one having only the first arm or a large one having the third arm or more.
