Suction cup of vacuum sweeper and vacuum sweeper using suction cup

Abstract

The invention provides a suction cup of a vacuum sweeper and the vacuum sweeper using the suction cup, and belongs to the technical field of road sweeping equipment. The suction cup of the vacuum sweeper comprises a main suction cup body, auxiliary suction cup bodies, a transmission piece and a driving mechanism hinged to the transmission piece. The auxiliary suction cup bodies are hinged to the transmission piece and the main suction cup body through lateral avoiding swing shafts. Each auxiliary suction cup body comprises an auxiliary suction cup main part and a lateral avoiding swing shaft hinge piece hinged to the corresponding lateral avoiding swing shaft, wherein the lateral avoiding swing shaft hinge piece is hinged to the auxiliary suction cup main part so that the auxiliary suctioncup main part can swing upwards when making contact with protrusions on the ground. When making contact with the protrusions on the ground, the auxiliary suction cup main parts can swing upwards relative to the main suction cup body, so that the situation that the ground clearance of the suction cup is increased due to lifting of the whole main suction cup body and the auxiliary suction cup bodies, and consequentially, the dust suction effect of the vacuum sweeper is affected is avoided, and the problem that the ground clearance of the suction cup is excessively large when the suction cup makes contact with the protrusions on a road is solved.

Description

technical field [0001] The invention relates to a suction cup of a vacuuming vehicle and a vacuuming vehicle using the suction cup. Background technique [0002] In order to achieve a wider vacuuming width, the vacuum truck generally adopts the installation of auxiliary suction cup structure, which is usually close to the road shoulder for suction operation. However, the current auxiliary suction cup structure is installed on the main suction cup through a hinge shaft, and the auxiliary suction cup is mounted on the main suction cup through a telescopic oil cylinder. The suction cup rotates to be parallel to the main suction cup for vacuuming. [0003] For example, the invention patent application with application publication number CN105568918A and application publication date of 2016.05.11 discloses a suction cup structure of a vacuum cleaner that can automatically avoid. The suction cup structure includes a main suction cup and two auxiliary suction cups located on both s...
