Abstract

The invention relates to road surface cleaning machinery, in particular to a road cleaning machine, which comprises a machine body and a cleaning device, wherein the cleaning device comprises two symmetrical cantilevers and a cleaning mechanism, the cantilevers are respectively arranged at two ends of a main shaft, and the main shaft is connected to the bottom of the machine body; the cleaning mechanism is arranged between the cantilevers through a shaft and is connected with a power gear of the motor through a transmission gear and a belt at the end part. The cleaning mechanism comprises a main brush and a disc brush, a main brush shaft is arranged between the cantilevers, a section of worm is additionally arranged at two ends of the main brush, and the end part of the brush disc is axially connected to the cantilevers and meshed with the worm through a worm wheel. The invention has the advantages that the cantilever structure enables the cleaning device to be contacted with the ground under the action of self weight, and the self weight of the cleaning device enables the cleaning mechanism to change along with the fluctuation of the road surface when meeting pits or bulges of the road surface, thereby being capable of better cleaning the road surface.

Description

road sweeper

technical field

The present invention relates to a road cleaning machine, in particular to a road cleaning machine.

Background technique

Road sweepers currently on the market include large motorized sweepers and small hand-push sweepers, as shown in Figures 1 to 2, known road sweepers include a body 01 and a sweeping device 02, and the sweeping device 02 is generally A cylindrical main brush with a brush plate or shaft, wherein the sweeping device is installed on the bottom of the body 01, the body 01 is supported by wheels, and the sweeping device 02 is in contact with the ground. The disadvantage of the prior art is that the sweeping device 02 cannot bear the weight of the machine body, otherwise the wear of the brushes will be greatly aggravated, thus affecting the service life of the brushes, and the brushes will wear out after several times of use. Therefore, the sweeping device 02 needs a shaft. It is installed on both sides of the bottom of the machine body. However, this method makes the sweeping device 02 fixed on the horizontal plane of the axis. When there is a small pit on the road surface, the brush cannot remove the garbage in the pit, as shown in Figure 3, so Caused inefficiency; And when encountering the situation that bumps are arranged on the road surface, then exacerbated the wearing and tearing of sweeping device 02, increased use cost. In view of the shortcomings and inconveniences of the above-mentioned known road sweeping machines, the applicant has developed a new type of road sweeping machine that can bear the dead weight of the sweeping device by using his professional vision and professional knowledge in the spirit of research, innovation and excellence.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a road sweeper that bears the self-weight of the sweeping device through a cantilever.

The present invention is realized through the following technical solutions, including a machine body and a cleaning device. The cleaning device includes two symmetrical cantilever arms and a cleaning mechanism. The cantilever arms are respectively arranged at both ends of the main shaft, and the main shaft is connected to the bottom of the machine body;

The cleaning mechanism shaft is arranged between the cantilevers, and the cleaning mechanism is connected with the power gear of the motor through the transmission gear and the belt at the end.

The cleaning mechanism includes a main brush and a disc brush. The main brush shaft is arranged between the cantilever arms. A section of worm is added at both ends of the main brush. The end of the brush disc is axially connected to the cantilever and meshes with the worm through the worm wheel.

The advantage of the present invention is that the cantilever structure enables the cleaning device to contact the ground under the action of its own weight, and the self-weight of the cleaning device enables the cleaning mechanism to follow the ups and downs of the road surface when encountering pits or protrusions on the road surface, thereby better clean the road.

Detailed ways

Below in conjunction with accompanying drawing 4 to 7, the preferred embodiment of the present invention is described further, comprise body 1 and cleaning device 2, described cleaning device 2 comprises two symmetrical cantilevers 21 and cleaning mechanism 22, and described cantilever 21 is separately arranged on main shaft 211 The two ends of the main shaft 211 are connected to the bottom of the body 1;

The cleaning mechanism 22 shaft is arranged between the cantilever arms 21, and the cleaning mechanism 22 is connected with the power gear 231 of the motor 23 through the transmission gear 2211 and the belt 24 at the end.

The cleaning mechanism 22 includes a main brush 221 and a disk brush 222. The axis of the main brush 221 is arranged between the cantilever 21. A section of worm 223 is added to the two ends of the main brush 221. The end of the brush disk 222 is axially connected to the cantilever 21, and The worm gear 224 meshes with the worm 223 .

During working state, referring to accompanying drawing 5, start motor 23, power gear 231 drives transmission gear 2211 through belt 24; The turbine 224 rotates, that is, the brush plate 222 follows the rotation to clean the road surface. When the road surface encounters a pit, refer to accompanying drawing 6, the cleaning mechanism 22 makes the cantilever 21 swing down and fit the ground under the action of its own weight, to achieve the effect of effectively cleaning the inside of the pit; Under the action of the cantilever 21, it swings upwards and fits the ground, thereby reducing the wear of the cleaning mechanism 22, prolonging the service life and improving the cleaning efficiency.

The above-mentioned embodiment only expresses one implementation mode of the present invention, and its description is relatively specific and detailed, but it should not be understood as limiting the patent scope of the invention. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention should be based on the appended claims.
