[0031] Working principle: When the unmanned sweeper 10 identifies the garbage that has not been swept away, such as chewing gum and fruit peel, and needs to remove the garbage that has been strongly adhered to the ground, the first electric push rod 3 is turned on to drive the support frame 2 to slide, so that the garbage is located between the cleaning roller 8 and the cleaning shovel 5 in the through hole 4. The support frame 2 and the cleaning shovel 5 are in contact with the ground, and then the second electric push rod 6 is turned on to drive the cleaning shovel 5 to slide, remove the garbage on the ground and transport it to the cleaning roller 8. The servo motor 9 drives the cleaning roller 8 to rotate, and the first electric push rod 3 on the cleaning shovel 5 is turned on. The garbage on the first arc surface 501 is swept into the collecting bucket 7 through the second arc surface 401, which makes it easy to quickly shovel the garbage and sweep it into the collecting bucket 7 for collection. The cover plate 103 elastically seals the upper opening of the support frame 2 through the damping shaft 102 and the damping spring, which makes it easy to reduce the probability of dust flying out of the device when the cleaning roller 8 is working. By setting the installation groove 201 and the limit strip 202, the collecting bucket 7 can be quickly installed in the installation groove 201 on the support frame 2, thereby improving the convenience of installing and removing the collecting bucket 7.
