Abstract

The utility model relates to a sweeping vehicle which is a manual sweeping vehicle. The utility model comprises a vehicle frame, a running mechanism, a drive mechanism, a speed changing mechanism, a steering device, a sweeping mechanism, etc. The utility model is characterized in that the front right side of the vehicle frame is provided with a front sweeping mechanism, a friction wheel is arranged on the sweeping mechanism, and the friction wheel disengages from or combines with a right front driving wheel in a frictional mode. The running mechanism comprises three wheels which are two front wheels and a back steering wheel. When the utility model is used, a front sweeping mechanism can efficiently sweep the edges of roads, and the sweeping effect is conspicuous. The back steering wheel enables the steering radius of the manual sweeping vehicle to be small, so the utility model has the advantage of flexible and convenient operation.

Description

Manual sweeping vehicle

The utility model relates to cleaning vehicle technical field.

The present motor-driven small-sized road-sweeper that uses, consumes energy, complex structure, deadweight are big, maintenance difficult, cost are higher; Chinese patent: the manpower cleaning car (patent No.: 91207897.9 publication numbers: CN2095223U), use human-powered vehicle, light and flexible, turn to freely, the cleaning effect is relatively good, but because the preceding cleaning brush of this manpower cleaning car is in the dead ahead of vehicle frame, cleaning road edge effect is relatively poor; Back deflecting roller is the two-wheel structure, makes turning radius bigger, can not fully satisfy instructions for use.

The purpose of this utility model provides the preceding right side of a kind of vehicle frame and is provided with cleaning agency, and back deflecting roller is the manpower cleaning car of single-wheel structure.

The utility model is to realize like this, manpower cleaning car, comprise vehicle frame, driving mechanism, driving mechanism, gear, steering mechanism, cleaning agency, arrestment mechanism and clothing case and tool box, it is characterized in that the preceding right side of vehicle frame is provided with preceding cleaning agency, this cleaning agency is provided with friction wheel, this friction wheel and right front driving wheel friction clutch; Driving mechanism is a three-wheel, and it comprises two front-wheels and a back deflecting roller.

It is remarkable that compared with the prior art the utility model has cleaning road edge effect, and turning radius is less, advantages such as flexible operation.

Below in conjunction with accompanying drawing the utility model is done to describe:

Fig. 1 is the utility model structural representation

Fig. 2 is preceding cleaning agency schematic diagram

Referring to Fig. 1, Fig. 2; The preceding right side of vehicle frame is provided with preceding cleaning agency, cleaning agency is by outrigger 10 before being somebody's turn to do, internal frame 25, extension spring 23, friction wheel 11, belt pulley 26,6 belts 9, upper connecting rod 4, lower connecting rod 22, little axle 7, protector 5, disk cleaning brush 8 is formed, outrigger 10 is fixedly connected with vehicle frame, one internal frame 25 is housed in outrigger 10, between outrigger 10 and the internal frame 25 extension spring 23 is installed, at internal frame 25 middle parts one friction wheel 11 is housed, with the friction wheel 11 coaxial belt pulleys 26 that are equipped with, the two axial ends of this Pulley shaft 27 stretches in the slotted eye 24 on the outrigger, the upper end of internal frame 25 is connected with pull bar 3, the front portion of internal frame 25 is connected respectively by pin axle 20, lower connecting rod 4,22, on, lower connecting rod 4,22 front end is connected with little axle 7, be connected with belt pulley 6 at little axle 7 middle parts, connect with belt pulley 26 on the friction wheel 11 by belt 9, for colliding the road edge in use, cleaning agency before avoiding is damaged, in little axle 7 bottoms protector 5 is installed, the other end of this protector 5 connects with the vehicle frame front end, in protector 5, be provided with spring 21, play the effect of buffering, connect a disk cleaning brush 8 in the lower end of little axle 7; During use, right front driving wheel 12 contacts with abrasion wheels 11, driving friction wheel 11 by this driving wheel 12 rotates, drive disk cleaning brush 8 and rotate by belt pulley 26, belt 9, belt pulley 6, little axle 7, cleaning road edge, before dust is swept into car, cylinder cleaning brush 14 by the car body bottom is swept in the ash bucket 13, when not needing the work of disk cleaning brush, by carrying on the hand lever 2 drive pull bars 3, internal frame 25 is upwards promoted, make friction wheel 11 separate contact, mention and break away from ground and stop operating thereby drive the disk cleaning brush with right front driving wheel; When the road edge was collided in the work of disk cleaning brush accidentally, then protector spring 21 shrank and plays a protective role.

Driving mechanism is a three-wheel, and it comprises two front-wheels 12 and a back deflecting roller 19, and steering mechanism is by steering wheel 1 and by chain 16, turns to sprocket wheel 17 transmissions; On the deflecting roller 19 of back, back vent 18 is installed, on back vent, be equipped with and turn to sprocket wheel 17, connect with steering wheel coaxial sprocket 15, make back deflecting roller 19 deflections by direction of operating dish 1 by chain 16, thereby make the manpower cleaning car turning radius less, operation more flexibly, conveniently.
