Sweeping and sucking type wet and dry road sweeper

Abstract

The invention relates to a sweeping and sucking type wet and dry road sweeper, belonging to the special-purpose vehicle technology field. The road sweeper comprises an automobile chassis. A main fan is arranged at the upper part of the beam in the middle of the chassis and a rotary sweeper brush is installed at the lower part. A blowback type suction nozzle is arranged at the back of the rotary sweeper brush. The upper part at the back of the chassis is provided with a dedusting and dust collecting device and a water tank. The water tank is connected with nozzle at the rotary sweeper brush. The dedusting and dust collecting device comprises a dustbin and a dust filtering chamber. One part of the dustbin is communicated with the suction nozzle through a dust pipe and the other part is connected with an air inlet of the centrifugal separator through a filter screen. The air outlet of the centrifugal separator is communicated with the inlet of the main fan. The dust outlet goes to the back door of the dustbin. The outlet of the main fan is communicated with the blowback mouth at the suction nozzle by the blowback pipe and is communicated with the air outlet and the dust filtering chamber. The upper part of the dust filtering chamber is communicated with the air by a filter barrel. The road sweeper can sweep in a dry way or a wet way, is not limited by the climatic condition, combines suction and sweeping, has high cleaning rate, simple structure and easy sanitary tipping.

Description

technical field [0001] The invention relates to environmental sanitation road cleaning equipment, in particular to a sweeping suction type dry and wet road sweeper, which belongs to the technical field of special vehicles. Background technique [0002] According to the applicant's knowledge, the current domestic road sweepers can be divided into wet water spray dust reduction and dry filter dust removal methods according to the dust reduction and dust removal methods. Wet road sweepers that spray water to reduce dust, when the ambient temperature is low in winter in the north, the water in the water tank is easy to freeze and cannot be used; while dry road sweepers that rely on filtration and dust removal are not suitable for use in rainy seasons or wet places, so , The road sweeper with a single method of wet dust suppression or dry dust removal is limited by the environmental and climatic conditions during use, and the utilization rate is low. [0003] The search found th...

[0005] Patent application number is 200820052390.7 and patent application number is 200610017385.8 Chinese patent application discloses two kinds of multifunctional road cleaning vehicles respectively, and the former mainly uses high-pressure water to wash the road surface, and the sludge is sucked into the sewage tank through the suction nozzle, and the structure is complicated. The water consumption is large, and there is no dust suppression and dust removal device for dry cleaning operations

The latter can only be used for dry cleaning operations. In rainy days or when the ground is wet, the dust collector is easily blocked by agglomerated dust and cannot work.
