The invention relates to the technical field of earthwork machinery, and discloses a cleaning device for a track beam of an earthwork hydraulic excavator. The cleaning device comprises a bottom frame and a placement plate, wherein a piezoelectric crystal is movably connected into the placement plate, a dielectric plate is movably connected to the bottom of the placement plate, a movable spring is movably connected to the bottom of the electric placement plate, the top of the bottom frame is movably connected with a positive plate, the top of the bottom frame is movably connected with a negative plate, and the interior of the bottom frame is movably connected with a piezoresistor. According to the cleaning device, when sludge falls on the placement plate, the dielectric plate moves downwards, the relative area between the positive plate and the negative plate is reduced, when the current between the positive plate and the negative plate is smaller than the maximum access voltage of a piezoresistor, a piezoresistor access, the piezoelectric crystal and the piezoresistor are electrically connected, and the piezoelectric crystal is electrified to generate vibration, so that the soil on the placement plate is shaken to be scattered, and subsequent cleaning is facilitated.

    本发明涉及土方机械技术领域,且公开了一种土方液压挖掘机履带梁的清理装置,包括底架和放置板,所述放置板的内部活动连接有压电晶体,所述放置板的底部活动连接有电介质板,电动放置板的底部活动连接有活动弹簧,所述底架的顶部活动连接有正极板,所述底架的顶部活动连接有负极板,所述底架的内部活动连接有压敏电阻。该土方液压挖掘机履带梁的清理装置,当淤泥落到放置板上,此时电介质板向下移动,使得正极板与负极板之间相对面积减小,当正极板与负极板之间电流小于压敏电阻的最大通路电压,压敏电阻通路,压电晶体与压敏电阻电性连接,压电晶体通电产生振动,从而使得放置板上的泥土被抖散,方便后续清理。
