Description

Technical Field

[0001] The utility model relates to the technical field of floor scrubbers, in particular to a full-aluminum brush plate lifting mechanism for floor scrubbers. Background Art

[0002] A floor scrubber is a cleaning machine suitable for cleaning hard floors and taking the cleaned dust and impurities away from the site. It has the advantages of environmental protection, energy saving, and high efficiency.

[0003] A disc brush assembly is provided at the bottom of the floor scrubber. Currently, the disc brush assembly can be raised and lowered to adjust its position mainly through a lifting motor or a lifting cylinder. For example, a Chinese patent with publication number CN108951491B provides a disc brush adjustment mechanism for a floor scrubber. Although the lifting and lowering adjustment range is simple, this central arrangement structure easily causes the normal line of the disc brush assembly to be arranged. In addition to arranging the drive motor, the installation space of the lifting structure must also be considered. The crowded structure installation is not conducive to the maintenance of the disc brush assembly. In view of this, we propose an all-aluminum brush disc lifting mechanism for a floor scrubber. Utility Model Content

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0022] Embodiment: A floor scrubber full aluminum brush plate lifting mechanism, see Figures 1 to 3 , including a brush plate cover 1 and a motor mounting seat 4. The top of the brush plate cover 1 is a symmetrical structure and is fixedly connected to two support arms 2. A group of cross frames 3 are arranged between the two support arms 2, and the terminal of the support arm 2 is movably connected to the bottom of the floor scrubber through a sliding assembly 7 (including a slider and a guide rail). The motor mounting seat 4 is horizontally fixedly arranged at the bottom of the floor scrubber, and a servo motor 5 is fixedly arranged on the motor mounting seat 4. A lifting assembly 6 is arranged at the output end of the servo motor 5, and the adjustment end of the lifting assembly 6 is fixedly connected to the terminal of the support arm 2. It is worth mentioning that the brush plate cover 1, the support arm 2, the cross frame 3, the motor mounting seat 4 and the lifting assembly 6 are all made of aluminum material. The lightweight design of the cast aluminum structure makes it longer in use. The utility model is different from the vertical lifting structure of the brush plate of the floor scrubber in the prior art. It adopts a horizontal lifting structure to drive the up and down lifting and adjustment of the brush plate assembly, which not only reduces the difficulty and number of structural arrangements in the vertical direction, but also the lightweight design of the cast aluminum structure makes it longer in use.

[0023] Specifically, the lifting assembly 6 includes a lifting frame 601, and a cam 602 is arranged on the side of the lifting frame 601 close to the servo motor 5. The large end of the cam 602 is coaxially connected to the output end of the servo motor 5, and the small end of the cam 602 is movably connected to the high end of the lifting frame 601. A group of lifting columns 603 are arranged on the side of the lifting frame 601 close to the support arm 2. It is worth noting that the lifting frame 601 is a hollow tripod. Further, the lifting assembly 6 also includes a stress frame 604, which is fixedly arranged between the two support arms 2 terminals, and the stress frame 604 is fixedly connected to one of the cross frames 3 through a group of angle braces 605. A movable groove 606 is opened on the stress frame 604 at a position relative to the lifting column 603. It is worth emphasizing that the movable groove 606 is arranged horizontally, and the guide part 603c is limited to slide in the movable groove 606. The utility model utilizes the driving force of the servo motor 5 to drive the cam 602 to rotate, so that the small end of the cam 602 makes a circular motion, so that the lifting frame 601 movably connected to the small end of the cam 602 can adjust the horizontal height in the radial direction following the small end of the cam 602, so that the stress frame 604 is driven by the lifting column 603 to drive the brush plate assembly to adjust the height along the direction of the sliding component 7 at the bottom of the floor scrubber, and the structure is simple and durable.

[0024] It is worth mentioning that the lifting column 603 includes a fixed portion 603a, a screw-connected portion 603b and a guide portion 603c; the fixed portion 603a is fixedly arranged on the lifting frame 601, the screw-connected portion 603b is movably and detachably connected to the fixed portion 603a, and the guide portion 603c is movably and detachably connected between the fixed portion 603a and the screw-connected portion 603b. The utility model further designs the lifting column 603 as a replaceable structure, and the guide portion 603c is movably and detachably connected to the fixed portion 603a through the screw-connected portion 603b. Once the guide portion 603c and the movable groove 606 are highly worn during use, they can be easily repaired and replaced.

[0025] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
