The working principle of the pedal self-propelled sweeper is as follows:
during operation, the staff shifts main drive gear to meshing with first driving gear through switching the action bars, then tramples the pedal of automobile body forward according to the driving mode of bicycle, drives back sprocket through the walking chain belt and rotates forward to the drive vehicle moves forward. In the moving process, the main transmission gear is coaxially arranged on a rear wheel rotating shaft of the vehicle body and is shifted to be meshed with the first driving gear, so that part of pedal driving force is transmitted to the first driving gear by the main transmission gear, and then the first driving gear transmits the power to the rolling broom through the first driven gear and the first chain wheel structure, so that the rolling broom is driven to rotate (the rotating direction is the same as the rotating direction of the wheels); further, because the diameter of the first lower chain wheel in the first chain wheel structure is smaller than that of the rear chain wheel of the vehicle body, when the vehicle travels, the rolling broom rotates at a faster rotating speed, so that the garbage on the ground can be pushed and swept to the temporary storage hopper.
When needs shift to the collection when fighting the rubbish in the fill of keeping in, the vehicle stops earlier, then stir main drive gear to mesh with second drive gear through switching action bars, at this moment, first driving gear is in the separation state, then the staff tramples the pedal of automobile body backward, drive back sprocket backward through the walking chain belt and rotate, thereby drive back wheel axis of rotation and final drive wheel and rotate (same with current bicycle, be equipped with one-way bearing between back wheel axis of rotation and the wheel, only can forward drive wheel, will take place to skid relatively backward, therefore the wheel does not move). Because main drive gear and second drive gear mesh, so main drive gear will some pedal drive power transmission to second drive gear on, then second drive gear through second sprocket structure with power transmission to the fill of keeping in to the drive is kept in the fill and is made ascending removal, moves to the rear of collecting the fill, thereby conveniently shifts the rubbish in the fill of keeping in to the collection and fights. After transferring rubbish to collecting the fill, the staff tramples forward again and steps on pedal to the fill that will keep in descends, cleans the work and makes ready once more.

when the bicycle works, a worker shifts the main transmission gear 7 to be meshed with the first driving gear 8 through the switching operation rod, then pedals of the bicycle body 1 forwards according to the driving mode of the bicycle, and the rear chain wheels 1-3 are driven to rotate forwards through the walking chain belts 1-4, so that the bicycle is driven to move forwards. In the moving process, the main transmission gear 7 is coaxially arranged on a rotating shaft 1-2 of a rear wheel 1-1 of the vehicle body 1, and the main transmission gear 7 is shifted to be meshed with the first driving gear 8, so that part of pedal driving force is transmitted to the first driving gear 8 by the main transmission gear 7, and then the first driving gear 8 transmits the power to the rolling broom 2 through the first driven gear 9 and the first chain wheel structure, so that the rolling broom 2 is driven to rotate (the rotating direction is the same as that of the wheels); further, since the diameter of the first lower sprocket 11 in the first sprocket structure is smaller than the diameter of the rear sprockets 1 to 3 of the vehicle body 1, the rolling broom 2 rotates at a faster speed when the vehicle travels, so that the garbage on the ground can be pushed and swept to the temporary storage hopper 3.
When the garbage in the temporary storage hopper 3 needs to be transferred to the collecting hopper 4, the vehicle is stopped firstly, then the main transmission gear 7 is shifted to be meshed with the second transmission gear 15 through the switching operation rod, at the moment, the first driving gear 8 is in a separation state, then a worker treads the pedal of the vehicle body 1 backwards, and the rear chain wheel 1-3 is driven to rotate backwards through the walking chain belt 1-4, so that the rear wheel 1-1 rotating shaft 1-2 and the main transmission gear are driven to rotate (the same as an existing bicycle, a one-way bearing is arranged between the rear wheel 1-1 rotating shaft 1-2 and the wheel, the wheel can only be driven forwards, and the wheel can be relatively slipped backwards, so that the wheel is not moved). Because main drive gear 7 meshes with second drive gear 15, so main drive gear 7 will some pedal drive power transmission to second drive gear 15 on, then second drive gear 15 will power transmission to the fill 3 of keeping in through the second sprocket structure to the drive is kept in the fill 3 and is made the rising removal, is up to moving to the rear of collecting the fill 4, thereby conveniently shifts the rubbish in the fill 3 of keeping in to collecting in the fill 4. After garbage is transferred to the collecting hopper 4, the worker tramples the pedals forward again, so that the temporary storage hopper 3 descends to prepare for cleaning again.
The present invention is not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be construed as equivalents and are included in the scope of the present invention.
