AI Technical Summary
The lifting structure of the existing sweeper roller brush lacks buffering when adjusting the height of the roller brush, which causes the roller brush to directly hit the ground when it drops, which easily causes damage.
A automatic lifting structure of the sweeper roller brush is designed. Through the combination of hydraulic cylinder, hydraulic rod, guide groove, guide block, connecting block, guide sleeve, guide rod, mobile seat, spring and connecting rod, the hydraulic cylinder drives the connecting block to lift and adjust the height of the roller brush, and provides buffering through the spring to avoid direct contact between the roller brush and the ground.
It effectively avoids damage caused by excessive impact force of the roller brush when it falls, improves the service life of the sweeper. At the same time, the stability and smooth movement of the roller brush are ensured through the limit design of the guide sleeve and guide rod.
