Abstract

The invention relates to a rear suspension device. The rear suspension device is detachably mounted on a chassis frame (11), and comprises an upper frame (71) and a lower frame (72), which are connected; the upper frame (71) extends backwards at the joint between the upper frame (71) and the lower frame (72); the rear end of the upper frame (71) is longer than that of the chassis frame (11). The rear suspension device is arranged on the chassis frame, and has the advantages that since the rigidity of the chassis frame is far higher than that of a rear gearbox body, the bonding strength is greatly improved; the width of the chassis frame is larger, and the width of the rear suspension device is increased accordingly, so that a mounted agricultural implement with larger width can be selected, and the farming efficiency is improved greatly; the rear suspension device is detachably connected with the chassis frame, and if the rear suspension device is damaged in farming, the rear suspension device can be quickly detached for replacement.
