Rolling brush pressing height control device of automatic driving rolling brush type sweeper

Abstract

The invention discloses a rolling brush pressing height control device of an automatic driving rolling brush type sweeper. The rolling brush pressing height control device comprises a rolling brush main shaft, the front and rear ends of the rolling brush main shaft are respectively hinged with the left ends of rolling brush swing arms; the right end of each rolling brush swing arm is hinged to the front end and the rear end of the rolling brush upper rotating shaft. The rear end of the rotating shaft on the rolling brush is fixedly connected with a second belt pulley; a rolling brush motor is arranged on the left side of the second belt pulley; a first belt pulley is mounted at a power output end on the rear side of the rolling brush motor; the first belt pulley and the second belt pulley are in linkage connection through a transmission belt; a servo motor is arranged above each of the front end and the rear end of the rolling brush; the output end of each servo motor is connected with one lead screw module. The movable sliding block on each lead screw module is connected with the right end of the rolling brush swing arm through a pull-up chain. According to the automatic driving rolling brush type sweeper, the descending height of the rolling brush during sweeping can be automatically adjusted in each sweeping and sweeping process, and the sweeping operation effect of the automatic driving rolling brush type sweeper is guaranteed.

Description

technical field [0001] The invention relates to the technical field of automatic driving of a rolling brush type sweeper, in particular to a control device for the depression height of a rolling brush of an automatic driving brush type sweeper. Background technique [0002] Autonomous driving is a hot field in recent years. With the formulation and implementation of relevant national policies, autonomous driving technology has developed rapidly in sanitation, and more and more autonomous driving sweepers are being tested on the road. [0003] For the self-driving sweeper, there is a sweeping roller brush on it. When cleaning, the roller brush needs to be lowered to contact with the road to be cleaned, and then the garbage on the ground is brought into the garbage bin of the sweeper through the rotation of the roller brush. In order to achieve the purpose of cleaning, when the cleaning operation is not performed, the roller brush needs to be lifted to make it off the ground t...

Problems solved by technology

[0004] However, for the existing self-driving roller brush sweeper, the lifting of the upper roller brush all depends on the limit device to limit the height of the main brush rising and falling.

When cleaning for a period of time, when the roller brush is worn out, the staff needs to manually adjust the limit device (for example, press the roller brush down by hand or with a tool) to continue to keep the height of the roller brush in contact with the ground when it is lowered, so , which increases the cost of human maintenance and the degree of human intervention, which affects the user experience of the self-driving roller brush sweeper
