Description
Technical Field
[0001] The utility model relates to the technical field of ride-on floor scrubbers, in particular to a brush plate pressure buffer device for a small ride-on floor scrubber. Background Art
[0002] A ride-on floor scrubber is a cleaning tool that allows the operator to clean the floor while sitting. It is suitable for cleaning large areas of the floor. At present, the structures of various floor scrubbers and sweepers are basically the same. Sweepers are mostly used to clean dust and other smaller particles of garbage, while floor scrubbers can clean oil, mud and other stains on the road. In the process of cleaning the floor, sweepers and floor scrubbers are used at the same time to perform cleaning and washing tasks respectively.
[0003] When a small ride-on floor scrubber is working, the brush disc rotates to clean the ground and the surface of objects. When the brush disc of the floor scrubber is working on a concave and uneven road surface, the brush disc will be subjected to greater vibration and impact due to the unevenness of the road surface, which will cause a collision between the brush disc and the ground, thereby causing damage to the brush disc.

The flexible joint type buffer support rod is distributed and connected in the through hole, the fixed block is connected to the buffer plate at the bottom of each buffer column, each buffer column passes through the flexible joint type buffer support rod and extends on the fixed brush plate, the limit block is fixed on the buffer column, a first buffer spring is sleeved on the outer circumferential wall of the buffer column between the bottom of each flexible joint type buffer support rod and the top of the fixed block, and a second buffer spring is sleeved on the outer circumferential wall of the buffer column between the bottom of the limit block at the top of each flexible joint type buffer support rod.
[0009] As a preferred solution of the utility model, the driving assembly includes a driving motor, and the bottom output end of the driving motor is connected to a connecting flange that matches and connects to the fixed flange on the top of the brush plate.
