The invention discloses a two-way circulation sweep-type multifunctional sweeper. The two-way circulation sweep-type multifunctional sweeper is an environmental sanitation special sweeper with the integrated functions of conducting running, sweeping and loading. The sweeper is an overall mechanism formed through the design of a sweeping device 12, a rubbish loading box 1, a power electromechanical walking mechanism, and an auxiliary electric sweeping side brush 19, wherein the sweeping device 12, the dustbin loading box 1, the power electromechanical walking mechanism and the auxiliary sweeping side brush 19 are in the same horizontal line and different directions. The sweeping device 12 is composed of three shaft rollers 4, a wide leather conveyor belt 2 and a sweeping board brush 3. The rubbish loading box 1 mainly comprises a dustbin 9, a rubbish baffle 5, a rubbish slide plate 18, and an elastic bottom-touch floor 8. The power electromechanical walking mechanism is mainly composed of a sweeping electromechanical unit 6, a walking electromechanical unit 14, an energy source 7, a vehicle frame 17, a chassis 16, vehicle wheels 15, a lifting device, a driving operating system 13 and the like. The specifications and the model numbers of the two-way circulation sweep-type multifunctional sweeper can be designed according to work needs and the magnitude of power, the application range is wide, the manufacturing cost is low, low energy is consumed in sweeping, and the two-way circulation sweep-type multifunctional sweeper is efficient and raises no dust, and has functions of sweeping rubbish, dust and snow, and draining water.
