Lifting mechanism for small electric sweeper disc brushes

Abstract

The invention provides a lifting mechanism for small electric sweeper disc brushes. The lifting mechanism comprises a bracket, an electric push rod and planar six-rod mechanisms, wherein each planar six-rod mechanism consists of a parallelogram mechanism, a connecting rod and a connector; and the parallelogram mechanisms and the electric push rod are both fixed to the bracket. The lifting mechanism for the small electric sweeper disc brushes has the following technical effects: 1) disc brushes are guided to perform translational lifting by adopting the planer six-rod mechanisms which are formed by the parallelogram mechanisms, so that the cleaning effect of the disc brushes is improved, the service life of the disc brushes is prolonged, and the aims of raising efficiency and saving energy are fulfilled; 2) by adopting the electric push rod and two planar six-rod mechanisms which are arranged symmetrically, the synchronous linkage lifting of the disc brushes on the two sides is realized, the consistency of the heights and the inclination angles of the disc brushes on the two sides is ensured, and the cost is reduced; 3) the electric push rod serves as a drive source, the power is taken from a storage battery of an electric vehicle very conveniently; and 4) the lifting mechanism is compact in structure, reasonable in layout and is matched with a vehicle frame conveniently.

Description

technical field [0001] The invention relates to a small electric cleaning vehicle, in particular to a lifting mechanism for a small electric cleaning vehicle disc brush. Background technique [0002] According to the needs of the sweeper to meet the function of sweeping the ground, the sweeping device generally consists of disc brushes on both sides and a roller brush at the bottom. During the cleaning operation, the disc brush should be lowered to contact the road surface, and the road surface should be sprayed and cleaned. For the existing small sweepers on the market, the lifting movement of the disc brushes on both sides is usually controlled separately, resulting in a large randomness in the working height and inclination angle of the disc brushes on both sides; the lifting trajectory of the disc brushes on both sides is usually a circular arc, and the lifting During the process, the inclination angle of the rotation axis of the disc brush will change continuously, an...

For the existing small sweepers on the market, the lifting movement of the disc brushes on both sides is usually controlled separately, resulting in a large randomness in the working height and inclination angle of the disc brushes on both sides; the lifting trajectory of the disc brushes on both sides is usually a circular arc, and the lifting During the process, the inclination angle of the disc brush rotation axis will change continuously, and different disc brush heights correspond to different disc brush inclination angles during cleaning operations.

This not only makes the cleaning effect unstable, but also makes the contact load of the disc brush uneven, reducing the service life of the disc brush
