Description

Technical Field

[0001] The utility model relates to the field of road cleaning equipment, in particular to a road sweeper. Background Art

[0002] A road sweeper is an efficient cleaning equipment integrating road cleaning, garbage recycling and transportation, which can be widely used in road cleaning operations in urban streets, highways, squares, docks, airports and other places, and can effectively improve the cleaning efficiency and improve the environmental sanitation. A road sweeper disclosed in TWM410140U has a drum brush 60 and a rotary brush 80 provided on at least one side, and the bristles 62 perform a cleaning action on the ground at the entrance 42 end of the dustpan 40. The above road sweeper has the following problems: 1. Its dustpan 40 is arranged in front of the drum brush 60. This layout causes the guide plate 43 of the dustpan 40 to contact the ground first when the vehicle moves forward. This contact actually blocks the garbage, making it difficult for the subsequent bristles to effectively gather and collect the garbage during sweeping, greatly reducing the cleaning effect; 2. There is no dust suction mechanism. During the cleaning process, especially when facing dust-like garbage, relying only on the bristles for cleaning is extremely likely to cause dust problems and secondary pollution. Summary of the Utility Model

[0003] The purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a road sweeper, which sets the garbage chamber behind the main brush, and improves the cleaning efficiency and effect through the cooperation of the main brush and the material shoveling plate and the auxiliary suction of the exhaust fan.

[0004] The technical solution of the utility model: A road sweeper includes:

[0005] A vehicle having a carriage with a garbage chamber inside, the front end of the carriage has an entrance, and the rear end of the carriage has an openable rear box cover;

[0006] A cleaning device is arranged at the front end of the vehicle, including a head frame, a main brush, a pair of side brushes located in front of the main brush, and a material shoveling plate. The main brush corresponds to the entrance of the carriage. The material shoveling plate is located behind the main brush and is a front-inclined structure from top to bottom. The upper end of the material shoveling plate is connected to the lower end of the carriage entrance, and its lower end is used to contact the ground. When the main brush rolls, it cooperates with the material shoveling plate to sweep the ground garbage backward into the garbage chamber communicated with the carriage entrance;

[0007] An exhaust fan is installed on the carriage, and the backward suction generated by the exhaust fan can guide the garbage to be sucked into the garbage chamber communicated with the carriage entrance through the material shoveling plate.

[0008] By adopting the above technical solutions, the utility model realizes the automatic cleaning and collection of road surface garbage, improving the cleaning efficiency. The headstock firmly supports the cleaning device to ensure the stability of the device during the cleaning process. The main brush and the side brushes cooperate to effectively clean the garbage on the road surface. Compared with the background technology, the garbage chamber of this application is ingeniously arranged behind the main brush. This design enables the main brush to first contact the garbage on the ground. During the rolling process of the main brush, its bristles can effectively gather and push the garbage towards the rear shovel plate. The front inclined structure of the shovel plate enables the garbage to smoothly slide down to the carriage entrance and is further sucked into the garbage chamber by the suction force generated by the exhaust fan, enhancing the garbage collection effect. The entire cleaning process is continuous and efficient, reducing the tediousness and time consumption of manual cleaning and being applicable to various road cleaning operations.

[0009] In summary, by setting the garbage chamber behind the main brush and through the cooperation of the main brush and the shovel plate as well as the auxiliary suction force of the exhaust fan, the road sweeper of the utility model successfully overcomes the defects in the background technology and improves the cleaning efficiency and effect.
