Handle-type main brush fine adjusting device

Abstract

The invention discloses a handle-type main brush fine adjusting device. The handle-type main brush fine adjusting device comprises a handle, a controlling connecting rod and a rolling brush, wherein one end of the controlling connecting rod is connected with the handle, and the other end of the controlling connecting rod is connected with a rotator; a tapered block is arranged on the rotator; a cross handle controls the advance and the recession of the tapered block by a screw rod in a rotating manner, and a wedged iron block matched with the tapered block can also move upwards and downwards; and the wedged iron block is connected with one end of a brushed metal, and the other end of the brushed metal is connected with the rolling brush. The control of the upwards and the downwards of the rolling brush plays a vital role to the service life of the rolling brush. The handle-type main brush fine adjusting device adopts brushed metal to control the upward and downward of the rolling brush, so as to effectively control the optimal joint point between the rolling brush and the ground through fine adjusting of the screw rod (cross handle); and the sweeping is clean and the service life of the rolling brush is improved.

Description

technical field [0001] The invention relates to a handle-type main brush fine-tuning device on an electric cleaning vehicle. Background technique [0002] As one of the important components on the electric sweeper, the roller brush is also one of the main consumables of the electric sweeper. Because the roller brush rubs against the ground during the cleaning process, the roller brush wears a lot. After a long period of wear, the distance between the roller brush and the ground gradually increases, resulting in unclean cleaning. This is because the staff replaced the roller brush with a new one. The old roller brush that came down is no longer in use. In fact, according to the test results, the old roller brush can continue to be used for a period of time, but the use of the roller brush has not been well adjusted up and down (lifting). Contents of the invention [0003] The object of the present invention is to provide a handle-type main brush fine-tuning device for fin...
