PROBLEM TO BE SOLVED: To provide a pulverization plowing-in device which performs pulverization and plowing-in of green manure crop, weed, etc. simultaneously to aim at improving work efficiency.SOLUTION: A rotation shaft 203 is laterally arranged in a bottom part of a machine body 1 of a self-travel vehicle mounted with an engine, the rotation shaft rotated by power of the engine. Plural hammer cutters 202 and plural tillage jaws 201 are mounted on the rotation shaft 203. The plural hammer cutters 202 are attached with phase difference on the rotation shaft 203 at equal intervals and the rotation shaft 203 is rotated in a reverse direction to a forward direction of the self-travel vehicle. The constitution enables simultaneous performance of pulverization and plowing-in of green manure crop, weed, etc. to improve work efficiency.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2016,JPO&INPIT【課題】作業能率の向上を目的として、緑肥作物等や雑草等の粉砕とすき込みを同時に行う粉砕すき込み装置を提供する。【解決手段】 エンジンを搭載した自走式車両の機体1底部にエンジンの動力で回転する回転軸203を横架し、この回転軸203にハンマーカッター202と耕耘爪201をそれぞれ複数個取り付ける。更に、前記複数個のハンマーカッター202を、位相差をつけて前記回転軸203に等間隔に取り付け、回転軸203を自走式車両の前進方向とは逆方向に回転させる。この構成により、耕耘作業において緑肥作物や雑草等の粉砕とすき込みを同時に行い、作業能率の向上を図る。【選択図】 図2
