The invention relates to the field of crawler falling prevention, and particularly relates to a crawler-type agricultural machine walking mechanism with a chain falling prevention crushing function. The mechanism comprises a walking mechanism main body, a crawler plate body, driving wheels and loading wheels, wherein a down pressing cavity is formed in the driving wheel; a falling prevention plateis movably mounted at the upper end of the down pressing cavity; a falling prevention rod is movably mounted in the loading wheel; the inner side of the crawler plate body is fixedly connected with an anti-falling protruding block; an obtuse-angle convex block is arranged on one side, facing the interior of the down pressing cavity, of the down pressing vibration plate; the acute-angle convex block is arranged on one side, facing the exterior of the down pressing cavity, of the fixed vibration plate; vibration is generated by contact collision, edges and corners of the stones are vibrated tobe flat or broken; the effect of preventing pebbles from falling off the chain is improved; and a vibration cavity is formed in the falling prevention plate, and a vibration block in the falling prevention plate is pentagonal, so that when the down pressing vibration plate makes contact with the fixed vibration plate to generate vibration, the vibration block can make collision contact with the vibration cavity through edges and corners on the outer side of the vibration block, and therefore the vibration frequency transmitted to stones to be shattered and discharged is further increased.

    本发明涉及履带防脱领域,具体为一种具有防脱链的破碎功能的履带式农机行走机构,包括行走机构主体、履带板体、主动轮、负重轮,主动轮内部开设有下压腔,下压腔上端活动安装有防脱板,负重轮内部活动安装有防脱杆,履带板体内侧固定连接有防脱凸块,通过下压震动板朝向下压腔内部的一侧的钝角凸块,与固定震动板朝向下压腔外部的一侧的锐角凸块,接触碰撞产生震动,使得将石子棱角震平或者震碎,使得提高防止石子脱链的效果,再通过防脱板内部开设有震动腔,且其内部的震动块为五边形设置,则当下压震动板与固定震动板接触产生震动时,震动块能通过其外侧的棱角与震动腔碰撞接触,从而进一步提高传递到石子上使其震碎排出的震动频率。
