PROBLEM TO BE SOLVED: To provide a piece of soil plowing equipment in which a soil plowing blade is replaceable as well as firmly mountable on a base body in spite of an attachable/detachable type.SOLUTION: In the lower part of a base body 1, an insertion force support plate 5 is installed that has a plate surface in a direction orthogonal to the insertion direction into the ground (a) of a soil plowing blade 4. In the rear side of this base body 1, a rear support part 6 is projectingly installed and, in the projecting tip end of this rear support part 6, a driving force support plate 7 is installed that has a plate surface parallel to the insertion direction into the ground (a) of the soil plowing blade 4. In the base of the soil plowing blade 4, a first mounting plate 8 is provided which is freely attachably/detachably overlapped and fitted with the insertion force support plate 5. Also, in the rear of the proximal end side of the soil plowing blade 4, a second mounting plate 9 is provided which is freely attachably/detachably overlapped and fitted with the driving force support plate 7. In the lower part of the base body 1 or in the rear support part 6 projectingly installed to the rear side of the lower part of the base body 1, a treadle part is installed.COPYRIGHT: (C)2014,JPO&INPIT【課題】土起こし刃を交換可能であると共に、着脱式でありながら土起こし刃を基体に強固に取付可能な土起こし器を提供すること。【解決手段】基体1の下部に、土起こし刃4の地面aへの差し込み方向と直交する方向に板面を有する差込力支持板部5を設け、この基体1の後方側に後方支持部6を突設し、この後方支持部6の突出先端部に、土起こし刃4の地面aへの差込方向と平行な板面を有する起動力支持板部7を設け、土起こし刃4の基部に、前記差込力支持板部5に着脱自在に重合止めする第一取付板部8を設けると共に、土起こし刃4の基端側の後部に、前記起動力支持板部7に着脱自在に重合止めする第二取付板部9を設け、この基体1の下部若しくは基体1下部の後方側に突設した後方支持部6に足踏み部3を設ける。【選択図】図2
