Description

  The present invention relates to a planting hole drilling apparatus and a drilling method for planting a plant on a planting site such as a slope.

When a plant is planted in a planting site such as a wasteland or a slope, a planting hole for planting the plant in the planting site is dug, and a plant seedling is planted in the planting hole. Such planting work has often been performed manually.
However, when the ground of the planting ground is hard, it takes time to manually drill the planting hole, which is inefficient.
In addition, when the planting site is a slope such as a slope, it is difficult for an operator to maintain a stable posture at the time of excavation, and there is a safety problem, and it is difficult to perform excavation work efficiently.
Therefore, it is conceivable to improve the work efficiency using various mechanical devices, but it requires a large amount of money to prepare various dedicated machines according to the geology and construction environment of the planting site.

An impact-type breaker (see Patent Document 1) used for crushing rocks, concrete structures, road pavements, etc., and dismantling refractories for firewood blast furnaces, etc. Although it is conceivable to use it, the conventional breaker is not suitable for excavating a planting hole because the rod has a shape intended for crushing.

This planting hole excavating apparatus 1 is configured by mounting a planting hole drilling rod 3 on an impact breaker 2 and mounted on a hydraulic excavator 4.
The impact breaker 2 is a hydraulic breaker and includes a known hydraulic striking mechanism (not shown), and a shank portion 31 of a planting hole excavation rod 3 is mounted on a front head 21. The planting hole excavation rod 3 has a large-diameter portion 32 corresponding to the size of the planting hole 5 below the shank portion 31, and the tip 33 has an inverted frustoconical shape.

In addition, the large diameter part 32 and the front-end | tip part 33 can select size, a shape, etc. arbitrarily according to the condition of the field.
The large-diameter portion 32 and the tip portion 33 may have an integrated structure. For example, as shown in FIGS. 4 and 5, the excavation block 35 and the protector 36 that can be attached to and detached from the rod body 34 are provided. By exchanging the rod 3 as a whole and exchanging the excavation block 35 and the protector 36 with different sizes as appropriate, the planting holes 5 with different sizes can be excavated according to the size of the plant 6 to be planted. it can. Here, the excavation block 35 has a conical circular stepped inclined surface of the inverted frustoconical shape of the distal end portion 33.

Further, in a place where the ground is compressed during excavation and the excavation of the planting hole 5 is difficult, the angle of the inclined surface of the tip 33 of the excavation block 35 is an acute angle as shown in FIGS. To make excavation easier.
Further, as shown in FIGS. 8 and 9, spiral grooves 37 and 38 are formed in the excavation block 35 and the protector 36, and the excavation block 35 (protector 36) is rotatably attached to the rod body 34. Thus, excavation waste can be easily discharged and excavation performance can be improved.

  Depending on the nature of the ground of the planting ground G, the excavated planting hole 5 is less likely to be self-supporting when the peripheral wall 51 is formed vertically, and may collapse. In such a place, as the planting hole excavation rod 3, as shown in FIG. 10, it is preferable to use a large-diameter portion 32 having a side surface 32S whose upper portion is enlarged in a tapered shape. Since a peripheral wall 51 having a tapered upper diameter is formed in the planting hole 5, the stability of the peripheral wall 51 is increased and it becomes self-supporting, so that the occurrence of collapse is prevented and construction accuracy and work efficiency are improved. .

  As shown in FIGS. 11 and 12, the planting hole excavation rod 3 includes a removable excavation block 35 and a protector 36 each having a side surface 32S in which the large diameter portion 32 is tapered and the upper portion is enlarged. 34 may be provided. In this case, the entire rod 3 is not replaced, but only by exchanging the excavation block 35 and the protector 36 with different sizes and taper angles as appropriate, according to the size of the plant 6 to be planted and the nature of the ground of the planting ground G. Planting holes 5 having different sizes and taper angles of the peripheral wall 51 can be excavated.

In the excavator 4, a working boom 43 and an arm 44 are supported by a swivel base 42 that can turn 360 degrees on a traveling carriage 41, and an impact breaker 2 is attached to the mounting bracket 22 at the tip of the boom 44. Installed in.
When excavating the planting hole 5 using the planting hole excavating device 1, the planting hole excavating device 1 is first attached to the arm 44 of the excavator 4 with the mounting bracket 22. Next, the excavator 4 is moved to the vicinity of the planting ground G, the swivel base 42 is swung, and the boom 43 and the arm 44 are raised and lowered so that the excavating device 1 for the planting hole is planted in the planting ground G. Move to 5 excavation position.

  After that, by operating the hydraulic hitting mechanism of the impact breaker 2 to hit the planting hole excavating rod 3, the planting hole excavating device 1 is pushed downward by the boom 43 and the arm 44 of the hydraulic excavator 4. The planting hole 5 is excavated in the planting site G. The planting hole excavation rod 3 hit by the hydraulic striking mechanism is configured so that the rod body 34 is covered with the protector 36, so that noise generated from the planting hole excavation rod 3 during excavation is reduced. If the protector 36 is made of rubber, the effect of reducing noise is great.

When the planting hole excavating rod 3 penetrates into the planting site G and the planting hole 5 is formed to a predetermined depth, the planting hole excavating device 1 is pulled up by the boom 43 and the arm 44 of the excavator 4. When the planting hole excavating rod 3 is extracted from the planting hole 5, the protector 36 prevents the peripheral wall 51 of the planting hole 5 from collapsing.
When the planting hole excavating rod 3 having a large-diameter portion 32 having a tapered side surface 32S with an enlarged upper portion is used, the planting hole 5 has a tapered upper portion as shown in FIG. A diametered peripheral wall 51 is formed. For this reason, extraction from the planting hole 5 of the planting hole excavating rod 3 is performed extremely smoothly. Further, even when the ground properties are not good, the peripheral wall 51 is highly stable and self-supporting, so that the occurrence of collapse is effectively prevented.

When the planting hole excavating rod 3 is extracted from the planting hole 5 and the excavation of the planting hole 5 is completed, the swivel 42 of the excavator 4 is swung, and the boom 43 and the arm 44 are raised and lowered. The excavation device 1 for planting holes is moved to the excavation position of the next planting hole 5, and the excavation work similar to the above is repeated thereafter.
In this way, the excavator 1 for planting holes is mounted on the excavator 4, and the excavator 1 for planting holes is moved to the position of the planting hole 5 in the planting site G by the boom 43 and the arm 44 of the excavator 4. Since the planting hole 5 is excavated, the excavation work of the planting hole 5 is mechanized, and the planting hole 5 can be excavated safely and efficiently even on a slope such as a slope.

The planting hole drilling device 1 can be mounted on a general-purpose hydraulic excavator 4 by using a generally used impact breaker 2, and special equipment and devices other than the planting hole drilling rod 3 are used. It is economical because it is possible to reduce costs without having to prepare the
In this embodiment, the excavation device 1 for planting holes is mounted on a hydraulic excavator, but it is needless to say that it can be mounted on a construction machine other than the hydraulic excavator according to the construction environment and conditions.
