Description

Foot-operated cleaning tricycle

Technical field:

The utility model relates to a kind of sanitary foot-operated cleaning tricycle that is used for.

Background technology:

At present, the sanitation of environment of avenue, road mainly is to clean with broom is manual by the environmental sanitation personnel, and labour intensity is big, and easy airborne dust recontamination environment.The patent No. is that 90222060.8 Chinese patent discloses a kind of foot-operated cleaning tricycle, can clean health automatically in the time of the tricycle walking, its main body is a foot-operated tricycle, axially establish a purging roller along the owner of the tricycle below tricycle, purging roller contacts with ground, between purging roller and the tricycle road wheel by gear drive, purging roller is given in road wheel walking transmission, purging roller is rotated, with rubbish sweep to tricycle with reservoir, realize cleaning automatically.But there is very big shortcoming in it, as: no matter need or not, as long as the tricycle walking, roll to purging roller with regard to transmission, purging roller contacts with ground again all the time, and tricycle is in the cleaning state all the time, both many efforts flog a dead horse, and can not select work and off working state again.In addition, fix because of purging roller, take normal replacing after sweeping seedling wearing and tearing, it is shorter to sweep the time that seedling utilizes, and runs into concavo-convex road surface and be difficult for sweeping only, and easily is obstructed.In addition, in order to be swept into the dead angle, roadside, it establishes the device of playing a minor role in tricycle the place ahead, and there is the angle of cut on play a minor role device and road surface, and tricycle when walking, the device of playing a minor role scans out the rubbish at dead angle, roadside, sweep on the work plane of purging roller, is cleaned by purging roller again.Same, its device of playing a minor role contacts with ground all the time, can not select work and off working state, not only many efforts but also flog a dead horse.

The utility model content:

The purpose of this utility model is to provide a kind of purging roller to suspend and the foot-operated cleaning tricycle of selectively operating and off working state thus.

The technical solution of the utility model is: its main body is a foot-operated tricycle, be positioned at tricycle below purging roller and with the corresponding reservoir of purging roller, driving gear is established in tricycle road wheel inboard, corresponding, on the main shaft of purging roller, establish driven gear, swing arm is established at two ends at the main shaft of purging roller respectively, swing arm has the chute that moves up and down for the purging roller main shaft, one of them swing arm is connected with drag-line, corresponding with drag-line, swing arm is connected with back-moving spring, and purging roller main shaft one end has pressure block, and the pressure block below is connected with spring, the pressure block top is connected with brake pad, the corresponding friction plate that has the gradient of establishing with brake pad above brake pad.

As a kind of improvement project of the present utility model be: establish the device of playing a minor role in foot-operated tricycle the place ahead, the device of playing a minor role has belt pulley, belt pulley and breast wheel are the band transmission, breast wheel and driving gear are the tooth transmission, the device of playing a minor role has folding arm, and the folding arm other end is located by hinge, and this end folding arm is connected with the fork body in the shift fork clutch, the contacts side surfaces of dialling body and breast wheel in the shift fork clutch, the breast wheel another side is connected with spring.

Use the foot-operated cleaning tricycle of the utility model, when the swabber advances by bike, swing arm is put under the pulling of drag-line, make purging roller be suspension, when putting in the swing arm, brake pad contacts with the friction plate of its top, because of friction plate has the gradient, brake pad along the gradient of friction plate when putting in the swing arm, brake pad is subjected to the downward extruding of friction plate, the interlock pressure block, the spring tension that overcomes the pressure block below moves down pressure block, because of pressure block is to be set on the purging roller main shaft,, make the separated attitude of driven gear on the main shaft of the driving gear of tricycle road wheel inboard and purging roller so cause the purging roller main shaft to move down along the chute in the swing arm.Purging roller is not worked, and it is laborsaving to advance, and does not flog a dead horse.When need clean, untie or open drag-line, swing arm is put downwards with return under action of gravity, purging roller is put down, during the swing arm bottom, brake pad loses gradually with the friction plate of its top and contacts, brake pad no longer is subjected to the downward extruding of friction plate, the spring reset of pressure block below, promote to move on the pressure block, interlock purging roller main shaft makes the purging roller main shaft along moving on the chute in the swing arm, the driving gear of tricycle road wheel inboard is mutually meshing with the driven gear on the main shaft of purging roller, and the walking of tricycle drives the purging roller rotary work.Purging roller directly sweeps rubbish in the reservoir by holder dirt plate.When rubbish in the reservoir when a certain amount of, pour the rubbish of reservoir on the tricycle main dustbin.When not needing to clean, the pulling drag-line makes purging roller be suspension, drag-line is fixed getting final product again.The foot-operated cleaning tricycle of the utility model can be selected work and off working state easily, and no longer many efforts flog a dead horse.The suspension function of purging roller not only can change easy on and off fluctuating cleaning with the road surface, can also make the seedling of sweeping on the cylinder use bottom line.Same, in the foot-operated cleaning tricycle of the utility model, the device of playing a minor role is also liftable or put down, and can select work and off working state easily, and no longer many efforts flog a dead horse.
