摘要： A posthole digger has first and second spaced-apart, substantially upright, pivotably attached handles. First and second cooperating scoops extend from respective proximal ends of the handles. The scoops are moveable between a generally open position for penetrating the ground surface, and a generally closed position for excavating. A cleaning attachment includes a stationary hollow sleeve attached adjacent the proximal ends of the handles. An elongate slide rod is received within the sleeve and extends between the handles for sliding vertical movement relative to the handles. An inner scraper is attached to an end of the slide rod, and is positioned between the first and second scoops. A spring engages the slide rod and normally urges the inner scraper upwardly into a storage position adjacent a top end of the scoops. A foot extension is formed with the inner scraper and is depressed by the foot of a user against the force of the spring to move the inner scraper downwardly along the length of the scoops. An outer scraper is secured to the foot extension and resides in closely-spaced relation to an outside surface of the scoops. The outer scraper is movable in unison with the inner scraper to clean away accumulated earthen matter from inside and outside surfaces of the scoops in the open position.
摘要翻译： 柱孔挖掘机具有第一和第二间隔开的，基本上直立的，可枢转地连接的手柄。 第一和第二配合勺从手柄的相应近端延伸。 勺子可以在穿透地面的大致打开位置和用于挖掘的大致关闭位置之间移动。 清洁附件包括邻近手柄的近端附接的固定中空套筒。 细长的滑杆容纳在套筒内并且在手柄之间延伸以相对于把手滑动的垂直运动。 内刮板附接到滑杆的端部，并且位于第一和第二勺之间。 弹簧与滑动杆接合，并且通常将内部刮刀向上推入与勺子顶端相邻的储存位置。 脚部延伸部与内部刮刀形成并且被使用者的脚部抵抗弹簧的力而被压下，以沿着铲斗的长度向下移动内部刮刀。 外部刮板固定到脚部延伸部上并与勺子的外表面紧密隔开。 外刮板可与内刮刀一致地移动，以在打开位置清除勺内外表面积聚的土壤物质。

摘要： A posthole digger includes first and second spaced-apart and substantially upright handles for being gripped by a user at respective free ends. First and second cooperating blades depend from respective proximal ends of the handles. A cleaning attachment is located between the handles for removing accumulated earthen matter from an inside surface of the first and second blades when in the open position. An elongate rod extends between the handles, and is received within a hollow sleeve for sliding vertical movement relative to the sleeve. An inner scraper is attached to an end of the rod, and positioned between the first and second blades for reciprocating vertical movement along the length of the blades in the open position. A coil spring normally urges the inner scraper upwardly into a storage position adjacent to a top end of the blades. An extension is secured to the inner scraper for being depressed by the foot of a user against the force of the spring to move the inner scraper downwardly along the length of the blades.
摘要翻译： 钻孔挖掘机包括第一和第二间隔开的和基本上直立的手柄，用于由使用者在相应的自由端夹持。 第一和第二配合刀片从手柄的相应近端部分。 清洁附件位于手柄之间，用于当处于打开位置时从第一和第二叶片的内表面去除积聚的土壤物质。 细长杆在手柄之间延伸，并且被容纳在中空套筒内，用于相对于套筒滑动。 内部刮刀附接到杆的端部，并且定位在第一和第二刀片之间，用于在打开位置沿刀片的长度往复运动。 螺旋弹簧通常将内部刮刀向上推入与刀片的顶端相邻的存储位置。 延长部分固定到内部刮刀上，以抵抗使用者的脚部抵抗弹簧的力而沿着刀片的长度向下移动内部刮刀。
