Abstract

PROBLEM TO BE SOLVED: To provide a stump puller hardly causing damage, easy in repair work and capable of removing a stump by utilizing a holding traveling excavator by expanding a boom onto a traveling car body so as to be vertically moved, attaching an arm to the boom so as to be swung and freely attachably and detachably attaching an attachment with stump cutter to the top end of this arm. SOLUTION: In this stump puller 1, for example, an attachment 4 with a stump cutter 14 is freely attachably and detachably attached to a main body 2 of traveling excavator in place of a drilling bucket. The traveling excavator is a backhoe generally on the market, and on its main body 2, a boom 7 is expanded at the fore part of traveling car body 6 having crawlers 5 on both left and right sides so as to be vertically moved, and an arm 8 is attached at the top end of boom 7 so as to be swung. Besides, a cylinder 9 is arranged for swinging the arm 8 along with the boom 7, a cylinder 10 is arranged along with the arm 8, and a link 11 is connected at the top end of cylinder 10.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting machine capable of utilizing a hand-held traveling excavator such as a backhoe.

[0002]

2. Description of the Related Art In a golf course or the like, for example, in the event that pine worms are damaged, in order to prevent the spread, the damaged trees are cut down, and the remaining stubs are removed to a depth of 20 to 30 cm underground. Above, work such as putting grass is performed.
In the past, this was done by cutting the above-ground parts of the tree with a chainsaw and relying on human power to process the stumps. With such a method, not only is it difficult to treat a stump having a large diameter, but also excavation work with a hand tool tends to cause an accident.

An excavating bucket provided with a cutting blade is disclosed in Japanese Patent Application Laid-Open No. 7-250576. However, this method cuts an underground root that hinders excavation at the same time as excavation work, and cannot remove only a stump without excavation. Moreover, since the cutting blade remains attached to the bucket even during normal excavation work that does not require the cutting blade, the cutting blade is liable to be polished or damaged,
The service life is shortened.

SUMMARY OF THE INVENTION According to the present invention, a stump can be efficiently and safely removed using a hand-held traveling excavator, and there is no danger of unnecessarily digging the ground. An object of the present invention is to provide a root felling machine that is hardly damaged because it is used only and that can easily perform repair work such as blade sharpening.

[0005]

According to a root felling machine of the present invention, a boom can be raised and lowered on a traveling vehicle body, an arm can be swingably attached to the boom, and an attachment with a stump cutter is attached to a tip of the arm. It is configured to be detachably attached. When performing a stub removal operation, the stub is cut using an excavator mechanism by an attachment with a stub cutter attached to the traveling vehicle body via a boom and an arm. When performing a normal excavation work, the attachment with the stump cutter is replaced with the excavation bucket, and the original form of the excavator is returned.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a logging machine 1 according to the present invention
Instead of (see FIG. 5), an attachment 4 with a stump cutter is detachably mounted.

The traveling excavator is a commercially available backhoe, and the excavator body 2 projects a boom 7 to the front of a traveling vehicle body 6 having crawlers 5 on both the left and right sides so that the boom 7 can be raised and lowered. An arm 8 is attached to the tip of the arm so as to be swingable in the front-rear direction. An arm cylinder 9 for swinging the arm 8 is provided along the boom 7, a bucket cylinder 10 for swinging the excavating bucket 3 is provided along the arm 8, and a link 11 is provided at the tip of the bucket cylinder 10. Be linked. Usually, as shown in FIG.
Are detachably mounted via mounting pins 12.

As shown in FIGS. 2 and 3, the attachment 4 with a stump cutter includes two side plates 13 parallel to each other.
And a cutter 14 attached between the left and right side plates 13 at the lower front part thereof. Further, mounting holes 15 for inserting the mounting pins 12 are formed in the upper portion and the lower rear portion of the side plate 13, respectively. Left and right side plates 13
A support plate 16 is erected at the lower part of the side plate 13 by welding.
The flat plate-shaped cutter 14 is superposed on the upper surface of the support plate 16 and is detachably fixed by bolts 17.

The cutter 14 is made of tool steel, and its cutting edge projects forward from the side plate 13 and the support plate 16. The cutting edge of the cutter 14 is inclined at an angle of 10 to 60 degrees. As shown in FIG. 1, the upper part of the attachment 4 with the stump cutter is detachably and rotatably passed through the upper end of the arm 8 by the upper mounting hole 15 and the mounting pin 12 inserted therethrough. The lower part of the attachment 4 with the stump cutter is detachably and rotatably passed through the tip of the link 11 by the mounting hole 15 and the mounting pin 12 inserted through the mounting hole 15.

Accordingly, the boom 7 is operated in the same manner as when excavating by operating a normal backhoe with the excavating bucket 3 mounted thereon.
In addition to swinging the arm 8 and swinging the attachment 4 with a stump cutter in the direction of approaching or moving away from the vehicle body 6 by the bucket cylinder 10, the stump 18 can be cut by the cutter 14 as shown in FIG. . In addition, when performing a normal excavation work, the attachment 4 with the stump cutter may be removed, and the excavation bucket 3 may be mounted again.

[0011]

According to the rooting machine of the present invention, it is possible to cut a stump by using a traveling excavator only by replacing the excavating bucket with an attachment with a stump cutter. It is also efficient and does not needlessly excavate the ground at the same time as cutting. In addition to eliminating the need for a special cutting machine to remove stubs, the cutter is not used when performing normal digging work by changing the attachment with a stub cutter to a digging bucket. The advantages are great. Further, the attachment with the stump cutter can be removed from the traveling vehicle body, and repairs such as sharpening can be easily performed.
