Pressure-differential classification suction pickup sweeper

Abstract

The invention discloses a pressure-differential classification suction pickup sweeper, which comprises a sweeper chassis. A water tank, an auxiliary engine, a hydraulic driving system, a fan, a garbage can, a blowing-suction-type suction nozzle mechanism, a pure-suction-type suction nozzle mechanism, a sweeping mechanism and a sweeping spraying system are arranged on the sweeper chassis; and the hydraulic driving system and the fan are powered by the auxiliary engine, the blowing-suction-type suction nozzle mechanism is powered by the fan, the sweeping spraying system is powered by a chassis battery, the sweeping mechanism and the garbage can are powered by the hydraulic driving system, the blowing-suction-type suction nozzle mechanism and the pure-suction-type suction nozzle mechanism both communicate with the garbage can, the blowing-suction-type suction nozzle mechanism is used for conducting suction pickup on garbage with the large specific weight, and the pure-suction-type suctionnozzle mechanism is used for conducting suction pickup on garbage with the small specific weight. According to the pressure-differential classification suction pickup sweeper, the garbage, with the different specific weights, such as leaves, floating dust and earth and stone particles can be subjected to separated suction pickup, the pavement sweeping efficiency and cleanliness can be improved greatly, reentrainment can be reduced greatly, and the advantages of high operation efficiency, good cleaning effect, low energy consumption and the like are achieved.

Description

technical field [0001] The invention relates to the field of special vehicles, in particular to a brand-new cleaning vehicle. Background technique [0002] The suction system of a traditional garbage sweeper usually does not have a separate suction setting for garbage with a large specific gravity and garbage with a small specific gravity. trash pickup. Due to the large negative pressure, large airflow, and high air velocity required for picking up specific garbage, when picking up heavy garbage as a standard, it often has the following defects: (1) Under the airflow, the garbage with small specific gravity, such as leaves and dust, is not easy to settle in the garbage bin, and the leaves will block the dustbin outlet air mesh of the garbage bin, resulting in poor air outlet of the garbage bin and affecting the effect of garbage suction (2) A large amount of dust enters the fan, causing damage to the fan and reducing its service life; (3) The secondary dust is large; (4) T...

Due to the large negative pressure, large airflow, and high air velocity required for picking up specific garbage, when picking up heavy garbage as a standard, it often has the following defects: (1) Under the airflow, the garbage with small specific gravity, such as leaves and dust, is not easy to settle in the garbage bin, and the leaves will block the dustbin outlet air mesh of the garbage bin, resulting in poor air outlet of the garbage bin and affecting the effect of garbage suction (2) A large amount of dust enters the fan, causing damage to the fan and reducing its service life; (3) The secondary dust is large; (4) The operating power is large and the energy consumption is large

[0003] At present, there are domestic studies on the classification and collection of garbage with large specific gravity and garbage with small specific gravity, such as the Chinese invention patent "Multifunctional Road Sweeper" with the publication number CN101392503A, and the Chinese utility model patent "New Model" with the publication number CN206486855U. "Garbage Sweeper" and the Chinese invention patent "A Yongyun Unblocked Sweeping and Suction Street Sweeper" whose publication number is CN107304552A, although the schemes disclosed in these patented technologies above can all solve the specific garbage and the specific gravity in varying degrees Small garbage classification and collection problems, but its structure is relatively complex, and the required operating power and energy consumption are relatively large
