Description

Pavement sweeping machine

Technical field:

The present invention relates to road refuse cleaning machinery, be meant pavement sweeping machine.

Background technology:

At present, utilize machinery cleaning road rubbish can be divided into two big classes, a class is the dynamic power machine pavement cleaning vehicle, and a class is a hand push machinery pavement cleaning vehicle (machine).Energy consumption is big in the work of dynamic power machine pavement cleaning vehicle, and noise is big, complex structure, maintenance cost height, motor exhaust contaminated environment.So hand push machinery pavement cleaning vehicle rises gradually.As 2,830,508 1 kinds of hand push scavenging machines of Chinese patent CN, it is made up of casing, support, disc brush, rotary broom, two road wheels and handspike, wherein, be fixed with big belt wheel on the wheel shaft of road wheel, be fixed with small pulley on the wheel shaft of rotary broom, between drive the rotary broom rotation by driving-belt, the wheel shaft two ends of rotary broom are fixed with bevel pinion; The disc brush that horizontally rotates is fixed on the left and right sides of support front portion, and the back fixation of disc brush has big angular wheel, the bevel pinion engagement on the wheel shaft of this big angular wheel and rotary broom, and bevel pinion has driven disc brush and has horizontally rotated; Be fixed with garbage shovel in the rotary broom back.Shortcoming is: the complicated efficient of transmission mechanism is low, can only keep straight on, and it is very inconvenient to turn round.Because garbage shovel is fixed on the support, runs into obstacle and promptly is stuck.

As Chinese patent CN 2538846 Environmental sanitation cleaning vehicles, it is that driving wheel and a front-wheel are the trolley that directive wheel is formed by two trailing wheels, comprise roll brush and preceding perpendicular brush, back wheel shaft by chain drive, gear drive with transmission of power to rotating shaft (can drive the roll brush this moment rotates), by gear drive, chain drive, bevel gear transmission, erect the turning cylinder (rotation of perpendicular brush before making this moment) of brush before sending power to again.Brushing radially in roll in addition, section is with strip plastics collecting bag.Shortcoming is: can only keep straight on, it is very inconvenient to turn round.Adopt multiple tooth wheels and chain drive, complex structure.

Summary of the invention:

The purpose of this invention is to provide a kind of pavement sweeping machine, characteristics are to adopt the Bowden cable transferring power that rotary broom is rotated, front-wheel and disc brush are fixed on the same L axle, but the trailing wheel left-right rotation changes the scavenging machine direction of travel, and the cambered garbage hanging shovel is rotatable and upwards promote.This pavement sweeping machine, comprise cover, mainframe, front-wheel, trailing wheel, driven toothed wheel, disc brush, rotary broom, cambered garbage hanging shovel, garbage collection box and handspike and Bowden cable, wherein, trailing wheel is a left and right sides two-wheel, left side wheel is provided with initiatively toothed wheel, and both are one, and the driven toothed wheel is fixed on the driven toothed wheel shaft, the driven toothed wheel shaft is fixed on the mainframe by bearing block, initiatively the engagement of toothed wheel and driven toothed wheel; Bowden cable one end is installed on the driven toothed wheel shaft, and the other end is installed on the rotary broom axle; The anterior two ends of mainframe are provided with the disc brush support set and are symmetrically fixed with the L axle, and front-wheel and disc brush are mounted respectively on the L axle; Be mounted with the cambered garbage hanging shovel that can upwards rotate in the rotary broom back, it is hung shovel eaves bottom and is overlapped on the garbage collection box edge.During walking, initiatively toothed wheel drives the driven toothed wheel and rotates, and the driven toothed wheel shaft drives Bowden cable and rotates, and Bowden cable finally drives rotary broom and does and turn clockwise, and front-wheel drives disc brush and does and horizontally rotate.

The invention has the advantages that: transmission of power adopts the Bowden cable transmission, the cambered garbage hanging shovel can upwards rotate, the anterior two ends of mainframe are provided with the disc brush support set and are symmetrically fixed with the L axle, front-wheel and disc brush are mounted respectively on the L axle, two front-wheels drive two disc brush by friction pulley respectively and rotate, trailing wheel can about nearly 40 the degree angular turn, scavenging machine arbitrarily changes direction of travel, its novel structure.
