Description

Technical Field

[0001] The invention relates to the technical field of road sweeping, in particular to a road sweeping machine. Background Art

[0002] The rural road network is becoming more and more complete, and its total mileage is increasing. However, rural roads face many cleaning challenges during use. At present, road cleaning mainly relies on two common methods: manual cleaning and using traditional road sweepers for cleaning operations.

[0003] The efficiency of manual cleaning is very low. Cleaners need to hold brooms and other tools and clean along the road section by section. Cleaning a large area of ​​road often requires a lot of manpower and a long time to complete. Manual cleaning consumes a lot of physical strength of cleaners and has high labor intensity. Manual cleaning is difficult to meet the needs of timely cleaning. Traditional road sweepers have alleviated the problem of low manual cleaning efficiency to a certain extent. The vehicle's own drive system drives the sweeping broom to rotate, and then sweeps and collects dust, garbage, etc. on the road surface. However, this type of sweeper itself has obvious limitations. One of the more prominent ones is that its sweeping broom needs to rely on the sweeper's own separate drive system to drive the operation, which means that the structure of the entire sweeper is relatively complex, which not only increases the manufacturing cost and maintenance difficulty of the equipment, but also the separate drive system is prone to failure during long-term operation. Once the drive component has a problem, it will directly affect the normal rotation and cleaning work of the sweeping broom, resulting in the sweeper being unable to operate normally, requiring additional time and manpower for maintenance, thereby affecting the overall progress and efficiency of road cleaning. For this reason, a road sweeper is proposed. Summary of the invention

[0004] In view of this, the present invention provides a road sweeper to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0005] The technical solution of the present invention is implemented as follows: a road sweeper comprises a traction mechanism and a sweeping mechanism, wherein the sweeping mechanism is installed on the top of the traction mechanism, and the traction mechanism comprises a rear axle, two wheels, a traction frame, a support plate, a traction ring and a transmission shaft; the two wheels are respectively installed at one end of two half-axles of the rear axle, the transmission shaft is installed at one end of the output shaft of the rear axle, the traction frame is hinged to one side of the rear axle, an outer side wall of the rear axle is hinged with an adjusting rod, an upper surface of the traction frame is fixedly connected with a fixing plate, an upper surface of the fixing plate is fixedly connected with a U-shaped plate, an inner side wall of the U-shaped plate is hinged with a sleeve, one end of the adjusting rod is inserted into the inner side wall of the sleeve, and the outer side wall of the adjusting rod is located at the top and bottom of the sleeve and is threadedly connected with a first fixing nut;

[0006] The cleaning mechanism includes a fixed plate, six brooms, six groups of through holes, six groups of U-shaped clamps and six groups of second fixing nuts. The six groups of through holes are symmetrically opened on the upper surface of the fixed plate, the six groups of U-shaped clamps are respectively inserted into the inner walls of the six groups of through holes, and the six brooms are respectively located between the six groups of U-shaped clamps and the fixed plate.

[0007] Further preferably, the traction frame is fixedly connected to one side of the rear axle, and one end of the traction ring is fixedly connected to one side of the traction frame.

[0008] Further preferably, the support plate is fixedly connected to the lower surface of the traction frame.

[0009] Further preferably, the six groups of the second fixing nuts are respectively threadedly connected to the outer side walls of the six groups of the U-shaped clamps.

[0010] Further preferably, the six groups of through holes and the six groups of the second fixing nuts each have four, and the six groups of the U-shaped clamps each have two.

[0011] The embodiment of the present invention has the following advantages due to the adoption of the above technical solution:

[0012] 1. During use, the present invention can adjust the angle of the rear axle by controlling the position of the adjusting rod, thereby adjusting the contact area between the broom and the road surface, controlling the cleaning area, and moving the traction vehicle. The fixed plate is driven to rotate through the transmission shaft, thereby driving the broom to rotate and cleaning the road surface. The cumbersome structure caused by the separate setting of the sweeping broom driving system is avoided, and the operation stability is improved through a more concise and efficient transmission design.

[0013] 2. Compared with manual cleaning methods, the present invention greatly improves the cleaning efficiency. It does not need to rely on a large amount of manpower to clean the road section by section. It can cover a large area of ​​the road in a short time and complete the cleaning task quickly, effectively solving the problem of time-consuming and labor-intensive manual cleaning. Compared with manual cleaning, it is suitable for cleaning work in different weather conditions and has more applicable scenarios.
