The invention provides a caterpillar band tensioning mechanism of a caterpillar band rotary cultivator, and relates to the field of agricultural machineries. The caterpillar band tensioning mechanismcomprises a caterpillar band, a caterpillar band frame and a tensioning assembly; the tensioning assembly is mounted at the right end of the upper side of the caterpillar band frame, the tensioning assembly comprises a tensioning seat, an electric telescopic rod is arranged in the tensioning seat, and a sliding arm is arranged on one side of the electric telescopic rod; one side of the sliding armis provided with a connecting arm; the connecting arm is provided with a driving wheel by bolts; a supporting rod is arranged on the upper side of the tensioning seat, and a riding wheel is arrangedon the upper side of the supporting rod. According to the caterpillar band tensioning mechanism, the electric telescopic rod is operated to stretch out and draw back to adjust the tensioning degree ofthe crawler band, the three tensioning states are switched and adjusted, the using requirements of different working conditions are met, a tensioning device is provided with the tensioning seat, thetensioning assembly is prevented from being exposed in air and soil, and the service life of the tensioning assembly is prolonged; the electric lifting rod ascends, a limiting block extends out of a groove, and the tensioning device is locked, so that the crawler band is in a continuous tensioning state; a pressure sensor transmits compression information of the riding wheel, and the tensioning degree is automatically adjusted according to the tensioning degree of the crawler band.

    本发明提供一种履带旋耕机的履带张紧机构,涉及农用机械领域,包括履带、履带架和张紧组件,张紧组件安装在履带架上侧右端位置,张紧组件包括张紧座,内部设有电动伸缩杆,且电动伸缩杆一侧设有滑动臂,滑动臂一侧设有连接臂,连接臂通过螺栓安装有主动轮,张紧座上侧设有支撑杆,支撑杆上侧设有托轮。本发明中,通过操作电动伸缩杆伸缩调节履带张紧程度,三种张紧状态切换调节,满足不同工况的使用需求,且张紧装置设有张紧座,避免张紧组件暴露在空气和泥土中,增加张紧组件的使用寿命;电动升降杆上升,限位块伸出凹槽,锁死张紧装置,使履带持续张紧状态;压力传感器传递托轮受压信息根据履带张紧程度,自动调节张紧程度。
