Detailed Description

The invention will be further elucidated below by means of non-limiting examples, with the understanding that the invention is not limited thereto.

As shown in fig. 1-4, the utility model relates to a sweeper limit brush turns to adjustment mechanism, including fixed frame 1, the setting of symmetry is at the limit brush 9 and the steering mechanism at fixed frame 1 both ends, limit brush 9 passes through steering mechanism and connects on fixed frame 1, fixed frame 1 is including violently managing 11, the symmetry sets up the connecting pipe 12 of the type of falling L at violently managing 11 both ends, steering mechanism includes angle pendulum 4, free bearing 5, turning handle 51, first air spring 6, second air spring 7, four-bar linkage 8, power cylinder 81, four-bar linkage 8 is parallelogram structure, go up the lower level and be same length dimension, the left and right side is another same length dimension, the upper and lower side is than left and right sides length.

The position of the joint of each connecting pipe 12 and the transverse pipe 11 is respectively hinged with an angular pendulum 4, and the suspended end position of each connecting pipe 12 is respectively hinged with a hinged support 5; the two angle pendulums 4 are hinged to form a linkage mechanism through the connecting rod 3, the connecting rod 3 is fixedly provided with the motor 2, the motor 2 is a push rod motor, the motor 2 is used for driving the connecting rod to axially move, so that the side brushes 9 connected with the two ends of the connecting rod 3 are driven to perform left-right swinging amount adjustment, synchronous retraction of the side brushes 9 on the two sides can be realized, and synchronous extension of the side brushes 9 on the two sides can also be realized. The abduction angle of the side brush 9 is set to be 45-50 degrees, so that the sweeping width is increased, the hard contact probability between the side surface of the sweeper and a cliff is obviously reduced, and unnecessary collision is avoided.

One vertical edge of the four-bar mechanism 8 is hinged with the connecting rod 3 by means of the hinged support 5, the other vertical edge of the four-bar mechanism 8 opposite to the vertical edge is connected with the side brush 9, two ends of the power cylinder 81 are respectively hinged with two opposite corners of the four-bar mechanism 8, the four-bar mechanism 8 is deformed by utilizing the axial displacement of the power cylinder 81, and a lifting adjustable structure of the side brush 9 relative to the fixed frame 1 is formed, in the embodiment, the upper edge, the lower edge, the left edge and the right edge of the four-bar mechanism 8 are designed according to the lifting adjustable 60mm, and the size accounts for 3/5 of the length of bristles of the. Height-adjustable about the limit brush 9 is convenient for do corresponding regulation according to the brush hair wearing and tearing condition of limit brush 9, guarantees that the effect of pasting to the ground of brush hair is better to this utilization ratio that improves limit brush 9 can also improve and clean the quality, avoids taking place to miss and sweeps the problem.
