Description

Quick-change type sweeper

Technical Field

The utility model relates to the technical field of sweeper equipment, in particular to a quick-change sweeper.

Background

The road sweeper is novel efficient sweeping equipment integrating road sweeping, garbage recycling and transportation, can finish the work of ground sweeping, road curb cleaning, sprinkling water to the ground after sweeping and the like at one time, and is suitable for sweeping operations of various climates and different dry roads.

The sweeping structure of the sweeper mainly comprises a side brush and a roller brush, wherein the side brush and the roller brush are connected with corresponding hydraulic motors, and the side brush and the roller brush are driven by the hydraulic motors to sweep the passing road surface. During the cleaning process, the appropriate side brush and roller brush need to be replaced according to the road surface condition to be cleaned (such as road type, garbage type, etc.), so as to improve the cleaning effect.

However, the conventional roller brush is generally mounted on the frame through a bearing seat or directly through a bearing, and the replacement of the roller brush is troublesome. For example, the utility model patent publication CN114808814a discloses an intelligent control sweeper with good self-cleaning function, and paragraph 0027 of the specification of the publication describes that "the inside of the chassis is movably sleeved with a roller brush, the front surface of the chassis is fixedly provided with a second motor and the output shaft of the second motor is fixedly connected with the roller brush", as can be seen from the above description and fig. 4 of the publication, the roller brush is movably sleeved (or rotationally assembled) on the chassis, and the output shaft of the motor is fixedly connected with the roller brush. The traditional assembly mode has the advantages of good stability, difficult deviation and the like of the roller brush, but correspondingly, the roller brush is relatively complex to replace. Conventionally, when the roller brush is replaced, the motor is detached firstly, so that the motor is separated from the roller brush; secondly, as the roller brush is arranged between the two underframes, one of the underframes needs to be disassembled to take down the roller brush; finally, the roller brush needs to be separated from the chassis, and under the condition that the connection mode is not disclosed in the publication, a common mode of general movable sleeve joint is to use a bearing, and the bearing is directly connected with the chassis in an interference fit mode, so that the roller brush is relatively troublesome to detach from the chassis, and the whole dismounting and replacing work takes a long time.
