<考案が解決しようとする課題> しかし、上記構造では次の問題がある。<Problems that the idea aims to solve> However, the above structure has the following problems.
従来例1の場合

形成した箇所でツースの肉厚が全幅に亘つて薄
くなり、強度が小さい。このため、岩石等を扱
う時の衝撃モーメントでツースの上記箇所が破
損し易く、耐久性に劣る。In the case of Conventional Example 1, the wall thickness of the teeth becomes thin over the entire width at the locations where the insertion grooves for the main edge and the sub-edge are formed, resulting in low strength. For this reason, the above-mentioned portions of the tooth are likely to be damaged by the impact moment when handling rocks, etc., resulting in poor durability.

力が作用した時に、この衝撃力はサブエツジか
らツース取付ボルトを経てメインエツジに伝わ
る途中でツース取付ボルトに剪断力として作用
するため、ツース取付ボルトが剪断され易く、
耐久性に劣る。(b) When a backward impact force is applied to the sub-edge during scooping work, this impact force acts as a shearing force on the tooth mounting bolt while being transmitted from the sub-edge to the main edge via the tooth mounting bolt, so the tooth mounting bolt is likely to be sheared. ,
Poor durability.

部分をも交換しなければならず、ロスが大き
い。しかも、サブエツジを交換するために全ツ
ース取付ボルト及び全ツースを分解しなければ
ならず、その交換作業に時間がかかる。このた
め、交換コストが高くつく。C. In general, the center part of the sub-edge is more likely to wear out.
Due to this localized wear, unworn parts must also be replaced, resulting in a large loss. Moreover, in order to replace the sub-edge, all the tooth mounting bolts and all the teeth must be disassembled, which takes time. Therefore, replacement costs are high.
ニ 横幅の異なる複数種のバケツトを製造する場
合、サブエツジは異なる種類のバケツトには寸
法が合わないため使えず、互換性がない。この
ため、部品管理が繁雑になる。D. When manufacturing multiple types of bucket carts with different widths, sub-edges cannot be used because the dimensions do not match the different types of bucket carts, and they are not compatible. This makes parts management complicated.
従来例2の場合
上記問題点イ、ハ及びニは解消されるものの、
問題点ロが残るうえ、新たに次の問題点ホ及びヘ
が生じる。In the case of conventional example 2, although the above problems A, C, and D are resolved,
Problem B remains, and the following problems E and F arise.
ロ すくい込み作業でサブエツジに後向きの衝撃
力が作用した時に、この衝撃力はサブエツジ取
付用のボルトに剪断力として作用するためボル
トが剪断され易く、耐久性に劣る。(b) When a backward impact force is applied to the sub-edge during the scooping operation, this impact force acts as a shearing force on the sub-edge mounting bolt, making the bolt likely to shear and resulting in poor durability.
ホ メインエツジ上側の各ツース間でサブエツジ
取付用のボルト、ナツトに土砂が溜り、バケツ
ト内の土砂放出時における土砂ばなれが悪くな
る。Home Sediment accumulates on the bolts and nuts for attaching the sub-edge between the teeth on the upper side of the main edge, making it difficult to loosen the sediment when discharging the soil from the bucket.
ヘ メインエツジにサブエツジ取付用としてボル
ト挿通孔を加工しなければならず、製造コスト
が高くつく。A bolt insertion hole must be formed on the main edge for attaching the sub-edge, which increases manufacturing costs.
従来例3の場合
上記問題点ロ乃至ヘは解消されるものの、問題
点イが残るうえ、新たに次の問題点ト乃至リが生
じる。In the case of conventional example 3 Although the above-mentioned problems B to F are solved, problem A remains, and the following problems T to F newly arise.
イ メインエツジ用挿嵌溝及びサブエツジ用取付
溝を形成した箇所で、全幅に亘つてツースの肉
厚が薄くなるため、破損し易い。B. The tooth becomes thinner over its entire width at the locations where the main edge insertion groove and sub-edge attachment groove are formed, making it more likely to break.
ト ツースのサブエツジ用取付溝に2個のサブエ
ツジの耳片を位置させるので、サブエツジの耳
片の前後方向長さが短くなり、強度が小さい。
しかも、サブエツジの耳片の突出基端部は急激
な断面積変化で応力集中が発生して破損し易
く、耐久性に劣る。Since the lugs of the two sub-edges are positioned in the sub-edge mounting grooves of the teeth, the length of the lobes of the sub-edge in the front-rear direction becomes short and the strength is small.
Moreover, the protruding base end of the sub-edge lug is prone to breakage due to stress concentration due to sudden changes in cross-sectional area, resulting in poor durability.
チ サブエツジの耳片より前側部分は自由端にな
つているため、上下方向に変形され易い。Since the front part of the subedge is a free end, it is easily deformed in the vertical direction.
リ サブエツジの耳片は横側面の一端縁寄り下部
から突出しており、サブエツジが非常に特異な
形状になつているので、その製造コストが高く
なる。The ear piece of the re-sub-edge protrudes from the lower part of the lateral side near one end edge, and the sub-edge has a very unique shape, which increases its manufacturing cost.

ものである。 That is, the first invention of the present application forms a fitting recess 4 on the side surface of each tooth 3 in the basic structure,
The front end of the fitting recess 4 is located in front of the front end of the insertion groove 7 of the tooth 3, and the fitting recess 4
The upper part of the sub-edge 8 is formed to have a length L corresponding to the mounting pitch P of the tooth 3, and the left and right side parts 9 of the sub-edge 8 are connected to the lower part of the fitting groove 7. These are inserted into the matching recesses 4, respectively.

ある。 Next, the second idea has the structure of the first idea,
The upper surface 12 of the fitting recess 4 is positioned higher than the lower surface 13 of the fitting groove 7 on the front side of the fitting groove 7, so that the left and right side portions 9 of the sub-edge 8 can be tightened with the tightening force of the tooth mounting bolt 11. It is clamped and fixed between the lower surface 14 of the fitting recess 4 and the lower surface 15 of the main edge 2.

体17をサブエツジ8上に固設したものである。 Further, the third invention is such that, in the structure of the first or second invention, a main edge protector 17 that covers the front surface 16 of the main edge 2 is fixedly installed on the sub-edge 8 at least between each tooth 3 .
<効果>
本願の第1考案乃至第3考案によれば、次の効
果(イ)乃至(チ)を奏する。<Effects> According to the first to third inventions of the present application, the following effects (a) to (h) are achieved.
(イ) 嵌合凹部を形成した箇所では両嵌合凹部間に
ツースの肉壁部があり、この肉壁部が強度部材
となつて、強度が大きい。このため、岩石等を
扱う時の衝撃モーメントでツースの上記箇所が
破損することを防ぐことができ、耐久性に優れ
る。(a) At the location where the fitting recess is formed, there is a tooth wall between the two fitting recesses, and this wall serves as a strength member and has high strength. Therefore, it is possible to prevent the above-mentioned portions of the tooth from being damaged due to the impact moment when handling rocks, etc., and the tooth has excellent durability.
(ロ) すくい込み作業でサブエツジに後ろ向きの衝

ルトに剪断力として作用しないので、ツース取
付ボルトの剪断を防いで、耐久性に優れる。(b) When a backward impact force is applied to the sub-edge during the scooping operation, this impact force is transmitted from the sub-edge to the main edge via the rear surface of the fitting recess, the tooth and the front end surface of the fitting groove, and creates a shearing force on the tooth mounting bolt. This prevents the tooth mounting bolt from shearing, resulting in excellent durability.
(ハ) 局部的な磨耗が発生した場合に磨耗したサブ

ルトを分解するだけでよく、その交換作業に時
間がかからない。このため、サブエツジの交換
コストが安価である。(c) When local wear occurs, only the worn sub-edges are replaced, and unworn sub-edges do not need to be replaced, so there is no loss. Furthermore, when replacing the sub-edge, it is only necessary to disassemble the tooth that fixes it and the tooth mounting bolt, and the replacement work does not take much time. Therefore, the cost of replacing the sub-edge is low.
(ニ) 横幅の異なるバケツトに対しても、ツースの
取付ピツチが略同じであれば、同じサブエツジ

理が簡素化される。(d) Even for buckets with different widths, if the tooth mounting pitch is approximately the same, the same sub-edge can be used, resulting in excellent compatibility and simplified parts management.
(ホ) メインエツジ上側の各ツース間にはボルト等
の突出物が無いので、各ツース間に土砂が溜る
ことがなく、バケツト内の土砂放出時における
土砂ばなれも良い。(e) Since there are no protruding objects such as bolts between the teeth on the upper side of the main edge, dirt does not accumulate between the teeth, and dirt is not easily spread out when releasing dirt from the bucket.
(ヘ) サブエツジ取付け用としてメインエツジにボ
ルト挿通孔を加工する必要がないので、製造コ
ストが安価である。(F) Manufacturing costs are low because there is no need to form bolt holes in the main edge for attaching the sub-edge.
(ト) ツースに嵌合凹部に挿嵌されるサブエツジの
両横側部は、前後方向に長くて強度が大きいう
え、その途中部に急激な断面積変化を起こさせ

ない。このため、サブエツジの両横側部の破損
を防いで、サブエツジの耐久性に優れる。(G) Both side parts of the sub-edge that are inserted into the fitting recesses of the teeth are long in the front-rear direction and have high strength, and there is no part in the middle that causes a sudden change in cross-sectional area, so there is no stress concentration. There is no part where this occurs. Therefore, damage to both side portions of the sub-edge is prevented, and the durability of the sub-edge is excellent.
(チ) サブエツジの前縁部は、その両横側部が嵌合
凹部に挿嵌されて強固に固定されているため、
上下方向に変形されにくい。(H) The front edge of the sub-edge is firmly fixed by inserting its lateral sides into the fitting recess.
Not easily deformed in the vertical direction.
