Description

Blowing device of combined type cleaning machine Technical Field The utility model relates to the field of road cleaning equipment, in particular to a blowing device of a combined type cleaning machine. Background In urban road cleaning operation, pedestrian accessory road is used as the main passing area of pedestrians, and the environmental sanitation condition directly influences urban image and resident traveling experience. However, the actual use of the pedestrian and the sidewalk is extremely complex, and parked bicycles, randomly discarded sundries and various stains which are difficult to clean frequently occur. The traditional sweeper only relies on the sweeping brush to sweep, and is difficult to thoroughly remove various garbage and stains in the face of the complex conditions, and cannot meet the increasingly strict environmental sanitation requirements. In order to solve the problem, the small new energy road sweeper adopts a scheme of arranging a flushing device in front of a vehicle, utilizes water flow impact to clean stubborn stains and garbage, and is matched with a sweeping brush to collect, so that the cleaning effect is improved to a certain extent. However, the small road sweeper has small volume and limited space, and the capacity of the water tank is relatively small, so that the water quantity requirement of continuous flushing cannot be met in long-time sweeping operation. Frequent water addition can not only interrupt cleaning work and reduce working efficiency, but also obviously increase operation cost, so that the scheme has larger limitation in practical application. Some manufacturers have attempted to solve this problem by adding blowers instead of flushing devices. The air blower blows pavement garbage to an area easy to clean through wind power, so that the cleaning width is widened, and the cleaning efficiency can be theoretically improved. However, in practical applications, it is found that, if an effective purging effect is to be achieved, a larger power is required for a common blower, which greatly increases the power consumption and seriously affects the whole vehicle endurance. If the power of the blower is reduced, the electric quantity loss can be reduced, but the wind power is insufficient, the garbage cannot be effectively purged, and the ideal cleaning effect requirement is difficult to achieve. Therefore, in the complex pavement auxiliary road cleaning operation, the current small road sweeper faces the problems of insufficient flushing water quantity, contradiction between blower power and endurance, and the like, and an innovative scheme is urgently needed to solve the contradiction between blower power and endurance, so that efficient, stable and durable cleaning operation is realized. The foregoing is provided merely for the purpose of facilitating understanding of the technical solutions of the present utility model and is not intended to represent an admission that the foregoing is prior art. Disclosure of utility model The utility model mainly aims to solve the technical problem that the existing cleaning machine is difficult to balance the contradiction between the cleaning function and the energy consumption during cleaning operation. In order to achieve the above object, the present utility model provides a blower device for a combined-type sweeper, which is used for a sweeper, and is characterized in that the blower device for the combined-type sweeper comprises: main fan, small fan, main fan air outlet blower air pipe and blowing pipe; the main fan is arranged in the sweeper, and the air outlet of the main fan is connected with the main fan; The blower air pipe is arranged in the main blower air outlet; The small fan is installed on the sweeper, one end of the air blower pipe is connected with the small fan, the other end of the air blower pipe points to the air blowing pipe, and the air outlet end of the air blowing pipe faces to the side surface of the combined sweeper. Preferably, the blower bellows is sleeved inside the blower pipe. Preferably, one end of the blowing pipe far away from the air outlet end is on the same horizontal line with the blower pipe. Preferably, the blowing pipe is arranged on a dustbin of the sweeper. Preferably, the blower air pipe is arranged inside a dustbin of the sweeper. Preferably, the air outlet end of the blowing pipe is in a conical and gradually-reduced design, and the flow cross section area is gradually reduced from the air inlet side to the air outlet side.
