である。(b) Prior Art In the greening industry, when trees are generally dug up and shipped in response to orders, they must be quickly dug up and shipped within a short period of time. Particularly when a large quantity of trees of a certain standard is ordered, the labor force for manual work will temporarily reach a peak, causing problems in recruiting staff and on time for delivery. For this reason, the excavator was developed to mechanize the work of digging up trees.
従来の掘取機においては、掘削刃を掘削長の相
違する各種の掘削刃を装着可能とする為に、掘取
刃回転軸による片持ち支持としていたので、掘削
刃の支持部の強度が弱く耐久性が低いという不具
合いが有つたのである。 In conventional excavators, the excavator blade was supported on a cantilever by the axis of rotation of the excavator blade in order to allow attachment of various excavator blades with different excavation lengths, so the strength of the support part of the excavator blade was weak. The problem was that it had low durability.
(ハ) 考案が解決しようとする問題点
本考案はこれらの点を改善すべく、掘削刃の前
端をも支持可能とすべく支持アーム２を設けたも
のである。(c) Problems to be solved by the invention In order to improve these problems, the present invention provides a support arm 2 so as to be able to support the front end of the excavating blade as well.

中に嵌入しないようにし、該支持アーム２の先端
から垂設した軸受体３の部分だけが僅かに土中に
嵌入すべく構成したものである。 However, when the support arm 2 is provided, the excavation resistance increases when the support arm 2 is inserted into the soil, so in order to prevent this, the support arm 2 is tilted upward in the present invention. The support arm 2 is placed so that even if the excavation blade 1 is inserted into the soil, the support arm 2 is not inserted into the soil, and only the bearing body 3 that is suspended from the tip of the support arm 2 is slightly inserted into the soil. It is designed to be inserted.
該軸受体３の部分は土中に嵌入するので、耐久
性が必要となるので、本考案においては該軸受体
３の前面に補強板３ａを設けたものである。 Since the bearing body 3 is inserted into the soil, durability is required, so in the present invention, a reinforcing plate 3a is provided on the front surface of the bearing body 3.

している。 The base of the support arm 2 of the excavating blade 1 is placed on a sliding plate 23 and tightened with a bolt 22 inserted into a long hole 5b of a sliding rail 5a. The sliding plate 23 can slide back and forth on the sliding rail 5a of the support 5, and when replacing the digging blade 1 with a digging blade 1' having a different digging length, the sliding plate 23 can be moved by loosening the bolt 22. It is adjusted back and forth, and after adjustment, it is tightened with bolt 22. As shown in FIG. 6, the shape of the excavating blade 1 is such that the blade is wide at the base and becomes narrower toward the tip.
(ヘ) 考案の効果
本考案は以上の如く構成したので、次のような
効果を奏するものである。(f) Effects of the invention Since the invention is constructed as described above, it has the following effects.
第１に、従来の如く掘削刃を掘削刃回転軸に対

端に設けた軸受体３により、掘削刃１の前端の前
端回転中心１ａ部分を枢支したことにより、強度
的に大となり、根元部Ａを掘削後にこれを抱いた
状態で持ち上げる、とができるのである。 First, instead of supporting the excavating blade in a cantilevered manner with respect to the excavating blade rotating shaft as in the past, the bearing body 3 provided at the tip of the support arm 2 supports the front end rotation center 1a of the front end of the excavating blade 1. By pivoting, the strength is increased, and it is possible to lift the root part A while holding it after excavation.
第２に、支持アーム２の先端の軸受体３の部分

軸受体３の部分が大きな負荷を受ける恐れがある
が、本考案においては、軸受体３の前面に補強板
３ａを設けたので、軸受体３自体の支持強度を向
上することが出来たものである。 Second, since the front end rotation center 1a of the excavating blade 1 is pivotally supported by the bearing body 3 at the tip of the support arm 2, the lower end of the bearing body 3 is connected to the ground together with the front end rotation center 1a of the excavating blade 1. If a large load is applied to the excavator blade 1 due to the possibility of it getting stuck inside,
Although there is a risk that the bearing body 3 may be subjected to a large load, in the present invention, a reinforcing plate 3a is provided on the front surface of the bearing body 3, so that the supporting strength of the bearing body 3 itself can be improved. be.
