[0025] Figure 3 is a schematic structural diagram of a width-adjustable chain brush device provided with a cleaning swing module according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Hereinafter, the preferred embodiments of the present invention will be described in detail with reference to the drawings, and the present invention will be further elaborated.

[0027] First, it will be combined with Figures 1 to 3 to describe a width-adjustable chain brush device according to an embodiment of the present invention, which is used for a sweeper and has a wide range of application scenarios.

[0028] Such asFigure 1 As shown, the width-adjustable chain brush device of the embodiment of the present invention comprises a brush frame 1, a chain module 2 and a bristle module 3. The brush frame 1 is arranged on a cleaning machine, the chain module 2 is arranged on the brush frame 1, the bristle module 3 is arranged on the chain module 2, and the cleaning machine drives the brush frame 1 to move and perform a cleaning action.

[0029] Specifically, Figure 1 As shown, the brush holder 1 comprises a pair of cross beams 11 and a longitudinal beam 12. The pair of cross beams 11 are parallel to each other, and the two ends of a longitudinal beam 12 are respectively connected to the pair of cross beams 11 and are perpendicular to the pair of cross beams 11. In this embodiment, the two ends of a longitudinal beam 12 are respectively connected to the center of the pair of cross beams 11, thereby forming an I-shape, which is compact, stable and beautiful.

[0030] Further, if Figure 1 As shown, the cross beam 11 and the longitudinal beam 12 are respectively telescopic.

[0031] Specifically, Figure 1 As shown, the chain module 2 includes: an upper chain component 21, a lower chain component 22 and a plurality of drive shafts 23. The upper chain component 21 is arranged on the upper surface of the brush holder 1; the lower chain component 22 is arranged on the lower surface of the brush holder 1, the upper chain component 21 and the lower chain component 22 are connected through a plurality of drive shafts 23, the lower chain component 22 is connected to the bristle module 3, the upper chain component 21 drives the lower chain component 22 to rotate, and the lower chain component 22 drives the bristle module 3 to rotate.

[0032] Further, if Figure 1 As shown, the upper chain assembly 21 includes: four upper chain wheels 211 and an upper chain 212. The four upper chain wheels 211 are respectively arranged on the upper surfaces of the ends of a pair of cross beams 11, and the upper chain 212 surrounds the four upper chain wheels 211 to form a rectangle.

[0033] Further, if Figure 1 As shown, the lower chain assembly 22 includes: four lower sprockets 221 and a lower chain 222. The four lower sprockets 221 are respectively arranged on the lower surfaces of the ends of a pair of beams 11. The four upper sprockets 211 correspond to the four lower sprockets 221 one by one. The driving shaft 23 passes through the beam 11 and is respectively connected to the corresponding upper sprockets 211 and the lower sprockets 221. The lower chain 222 surrounds the four lower sprockets 221 to form a rectangle.

[0034] Since the cross beam 11 and the longitudinal beam 12 are respectively telescopic, and the upper chain 212 and the lower chain 222 are wound around the upper sprocket 211 and the lower sprocket 221 at the end of the cross beam 11, therefore, according to the principle that when the perimeter of a rectangle remains unchanged and two opposite sides increase by a certain length, the two perpendicular opposite sides decrease by the same length, that is, when the lengths of the upper chain and the lower chain remain unchanged, when the longitudinal beam 12 extends, a pair of cross beams 11 will shorten synchronously, and when the longitudinal beam 12 shortens, a pair of cross beams 11 will extend synchronously, so that it can automatically adapt to various widths of the cleaning scenario and ensure the stability of the brush hair 32 structure.

[0035] Specifically, as Figure 1 , 2 shown, the brush hair module 3 includes a brush hair seat 31 and brush hairs 32. The brush hair seat 31 is respectively connected to the upper sprocket 211 and the lower sprocket 221, and the brush hairs 32 are arranged on the brush hair seat 31.

[0036] Furthermore, as Figure 3 shown, the width-adjustable chain brush device of the embodiment of the present invention further has: a cleaning swing module 4. The cleaning swing module 4 is connected to the brush holder 1 and the cleaning machine, and the cleaning swing module 4 can drive the brush holder 1 to rotate.

[0037] In this embodiment, as Figure 3 shown, the cleaning swing module 4 includes: a cleaning bracket 41 and a push rod 42; wherein, the cleaning bracket 41 is respectively connected to the brush holder 1 and the cleaning machine, and the brush holder 1 is movably connected to the cleaning bracket 41 through a hinge; both ends of the push rod 42 are respectively connected to the cleaning bracket 41 and the brush holder 1, and when the brush holder 1 rotates around the hinge, it drives the push rod 42 to expand and contract.

[0038] When working, the upper chain 212 and the lower chain 222 drive the brush hairs 32 to make a rectangular circular motion, and the relative expansion and contraction of the longitudinal beam 12 and a pair of cross beams 11 realize the change of the cleaning width of the brush hair module 3. And, driven by the push rod 42, the brush holder 1 is tilted at a certain angle, and only the brush hairs 32 on the lower side are retained. The cleaning and throwing materials always move in one direction and will not produce a material return phenomenon. At the same time, the brush holder 1 is driven by the push rod 42 and can be tilted forward or backward, realizing two-way work, and the inclination angle can be adjusted arbitrarily, so that it can reach any position and the front and rear end faces of the bottom of the cleaning area (such as the carriage) without any blind areas.

[0039] As above, with reference to Figures 1 to 3 described is the width-adjustable chain brush device according to the embodiment of the present invention, which can automatically adapt to various widths and inclination angles of the cleaning scenario, not only ensure the stability of the brush hair structure, and does not produce a material return phenomenon, but also can reach all positions and end faces of the cleaning scenario, without producing cleaning blind areas, ensuring the cleaning effect.
