る。Welding the L-shaped excavation edge forming sheet metal 6 to the tip of the arm 3, and welding the lower end edge 7a of the earth removal surface forming sheet metal 7 to the upper surface near the tip of this excavation edge forming sheet metal 6,
The reinforcing sheet metal 8 is welded to the excavation edge forming sheet metal 6 with a large bead amount while standing up from the excavation edge forming sheet metal 6, and the above-mentioned excavation surface forming sheet metal 7 is attached to the back of this reinforcing sheet metal 8. By positioning the lower edge 7a and welding both 7 and 8, it is possible to avoid direct stress from being applied to the welded part of the lower edge of the excavation edge forming sheet metal and the excavation top surface forming sheet metal during earth removal work. The structure is designed to suppress peeling at the welded portion.
排上面形成用板金7の両側には、側板9,9を溶接して
あり、そしてこの排土面形成用板金7と側板9の溶接個

部材10を側板突出部分に隣接させて溶接してあり、も
って排上面形成用板金7の両側部の摩耗耐久時間を長く
すべく構成しである。Side plates 9, 9 are welded to both sides of the sheet metal 7 for forming the earth removal surface, and at the welding point between the sheet metal 7 for forming the soil removal surface and the side plate 9, as shown in FIG. Both 7 and 9 are welded together with their edges protruding forward, and the protective member 10 is welded adjacent to the protruding portion of the side plate, thereby reducing the wear durability of both sides of the sheet metal 7 for forming the upper surface. It is designed to make it longer.
この保護形態は第5図に示すように、側板9と排土面形
成用板金7との溶接個所を保護部材10で覆うべく構成
してもよい。As shown in FIG. 5, this protection form may be configured such that the welded portion between the side plate 9 and the earth removal surface forming sheet metal 7 is covered with a protection member 10.
尚、補強用板金8は第4図に示すように排上面形成用板
金7に一体に設けるもよい。Incidentally, the reinforcing sheet metal 8 may be provided integrally with the sheet metal 7 for forming an upper surface as shown in FIG.
以上要するに、本考案は、冒頭に記した簡易ド−ザの構
造において、掘削縁形成用板金と排土面形成用板金の下
端縁部との溶接個所に前記掘削縁形成用板金から立上っ
た状態で補強用板金を一体的に溶接しである事を特徴と
する。In summary, in the structure of the simple dozer described at the beginning, the present invention has a structure in which the excavation edge forming sheet metal is raised up from the excavation edge forming sheet metal at the welding point of the lower end edge of the excavation edge forming sheet metal and the earth removal surface forming sheet metal. The reinforcing sheet metal is integrally welded in the same state.
つまり、掘削縁形成用板金よりも立上った状態に補強部
材を設けであるから、掘削縁形成用板金と排土面形成用
板金との溶接個所におけるビード量を多くすることがで
き、その溶接個所の剥離を簡単な構造の付加によって抑
制し得るに至った。In other words, since the reinforcing member is provided in a state that is higher than the sheet metal for forming the excavation edge, it is possible to increase the amount of bead at the welding point between the sheet metal for forming the excavation edge and the sheet metal for forming the soil removal surface. It has now been possible to suppress peeling at welded areas by adding a simple structure.
そして、このように補強部材を設けてビード量を多くす
るから、例えば、補強部材を設けずして、溶接の肉盛の
上に更に肉盛を重ねて、剥離を防止する場合に比して、
一度溶接した個所の酸化膜をハンマーなどで除去して、
表面をグラインダー仕上げし、その上に溶接を行なうと
いった多大な手間を少なくして充分な肉盛を得られる効
果がある。Since the reinforcing member is provided in this way and the bead amount is increased, for example, compared to the case where the reinforcing member is not provided and the welding layer is further layered on top of the welding layer to prevent peeling. ,
Remove the oxide film from the welded area with a hammer etc.
It has the effect of reducing the great effort of grinding the surface and performing welding on top of it, and obtaining sufficient overlay.
