Force applying device used for ground washing vehicle wiper on ground

Abstract

A device for a sweeping vehicle wiper to apply a force to the ground. The device comprises a connection plate (2) movably connected to a wiper assembly (1) of a sweeping vehicle, and the other end of the connection plate (2) is hinge-connected to a brush disk support (3). The brush disk support (3) is provided with a torsion spring (4), and the force-applying end of the torsion spring (4) applies a downward pressure to the connection plate (2). The device uses a light wiper assembly to meet the pressure requirement specified in the industry, thereby saving the manufacturing material. By means of a structure that the torsion spring applies a downward pressure, the space for mounting the tension spring may be greatly reduced, so that the structure is still applicable when the gap between the wiper assembly and the brush disk assembly is small, and therefore, the present invention has higher adaptability.

Description

technical field [0001] The invention belongs to the field of floor washing vehicles, and in particular relates to a device for applying force to the ground by a water scraper of a floor washing vehicle. Background technique [0002] When the floor washing machine cleans the ground, it relies on the brush plate to scrub the ground, and then the scrubbed dirt is stored by the water scraper. There are relevant regulations in the washing machine industry: when the brush plate and water scraper are working, a certain pressure on the ground must be ensured to ensure the scrubbing force of the brush plate on the ground and the relatively complete storage of the dirt after washing by the water scraper. [0003] There are generally two ways for the force application structure of the current water scraper to the ground. One is to use the weight of the squeegee itself to exert force on the ground. In order to ensure sufficient force, it is necessary to increase the gravity of the sque...

AI Technical Summary

Problems solved by technology

One is to use the weight of the squeegee itself to exert force on the ground. In order to ensure sufficient force, it is necessary to increase the gravity of the squeegee itself and use a heavier squeegee. However, this method increases the cost and cannot achieve To achieve a better effect; Another method is to install a tension spring at the connection of the water scraper, relying on the pull-down force of the tension spring to exert downward pressure on the water scraper, this structure needs to be installed between the water scraper and the brush plate The extension spring is limited to the scrubber with a large gap between the water scraper and the brush plate, which has poor applicability, and the large gap affects the scraping effect of the water scraper when turning
