Description

The rotary broom transmission mechanism of road sweeper

Technical field

The present invention relates to a kind of rotary broom transmission mechanism of road sweeper, belong to the environment sanitation facility technical field.

Background technology

The road sweeper custom is referred to as to call refuse cleaning vehicle, disposes two cover brooms on road sweeper usually, and a cover is the dish type broom, and it is a pair of that quantity has; Another set of is rotary broom, and quantity is independent one, promptly has one piece of broom axle only or claims cylinder, and the solid common quantity of peace is the broom of 3-6 handle on the broom axle.Aforesaid dish type broom, rotary broom are respectively by dish type broom transmission device and rotary broom work that transmission device drives.Contrast can be by obtaining very detailed understanding in the disclosed technical scheme of Chinese patent CN2484349Y.The positive effect of CN2484349Y is: guarantee that the two cover brooms and the road-sweeper speed of a motor vehicle are the relation of following in sb's footsteps, promptly the speed of a motor vehicle is fast, and the operating rate of broom cleaning is also fast, and vice versa.

But above-mentioned patented technology scheme also has shortcoming, because the rubbish state on the road often varies, meets some zone or certain bar road, the less or more phenomenon of highway section rubbish often.In case run into the highway section of relative clean, if the speed of a motor vehicle is fast, the wheel speed of travel of road-sweeper is improved, fast because of dish type broom operating rate so, thereby the part that can cause the dish type broom is swept the situation that is separated between silk appearance and the road surface, influence the dish type broom rubbish is driven to the zone of action of rotary broom, sweep for rotary broom and be thrown in the disposal box.Because the rotating speed of rotary broom is also fast, tend to cause the road surface to stir up a cloud of dust simultaneously; In case run into dirty relatively highway section, if the speed of a motor vehicle slows down, make the speed of travel of wheel of road-sweeper slow, can cause the adynamia of dish type broom, this two covers broom of rotary broom so or claim not enoughly, influence sweeps disposal box with rubbish.At and in order to remedy above-mentioned defective, Chinese patent application numbers 200620165344.9 has been recommended a kind of sweeping transmission mechanism of road sweeper.

But, the applicant thinks, all there is present insurmountable atypical technical problem in above-mentioned patent scheme, because rotary broom is arranged at the nearly middle part of disposal box, the case mouth of broom and disposal box is that the rubbish feeding mouth is in same horizontal plane basically or claims sustained height, obvious, disposal box is extremely limited to the saturation of rubbish, must come and go removal rubbish repeatedly in the course of work, thereby following 2 drawbacks of Yin Faing at least: the one, return rubbish concentrated area removal rubbish during for the utmost point, thereby continuous cleaning works is interrupted, influenced sweeping efficiency; The 2nd, return the consumption that frequently can increase the energy.Perhaps the someone can propose such query, that is exactly that capacity increase with disposal box is for example to the length of disposal box and highly improvement property dilatation, yet so thinking can produce the following problem of attending to one thing and lose sight of another again: only only depending on, the drum broom of this cover is rubbish can't be got rid of the depths of sweeping to disposal box effectively, moreover, also can make the interior rubbish of disposal box feedback behind the height that has surpassed rotary broom, occur and promptly return the phenomenon of inclining outward from the case mouth; The capacity that increases disposal box simply can cause the unbalance of road-sweeper body construction, hides some dangers for to safety.

Through applicant's preliminary conclusion of concentrating on studies, design, testing and draw for many years be, present for example by top act and form of structure the broom transmission mechanism particularly the rotary broom transmission mechanism can't use on the road sweeper that disposal box and rotary broom branch are arranged, for example organically be installed on the rubbish waggon of present environmental sanitation department employed van-type rubbish self-dumping.Because, the capacity that being used to of van-type rubbish dump car held the envelope of rubbish is comparatively gratifying, if two cover brooms of cleaning agency can be able to combine with it, then can yet be regarded as is a kind of good act that both can improve cleaning work efficient, energy conservation.But must perform the operation accordingly to the rotary broom transmission mechanism in the prior art and by the setting of rotary broom rotary broom that transmission mechanism drives.To this, the applicant can specifically to be put to the complete technical scheme of using and to retrieve in order to release, and does not all search referential technology enlightenment in professional journals " cleaning magazine " for example over the years and Chinese patent.

For example: .CN1318671A Chinese patent A), B) .CN2647914Y, C) .CN2769341Y or the like, A) automatic garbage scavenging truck of Jie Shaoing, though can be disposable finish from being swept into a series of operation such as shipment, but what it did not break away from yet that the applicant mentions in the above can't directly sweep rubbish and get rid of to the alleged dustbin of (sweep and be fed to) patent by being loaded on rolling and brushing broom on the drum shaft, and need transmit by conveyer belt, the road-sweeper of this structure is except existing tediously long car body shortcoming, the reliability of operation, safety all can be not satisfactory, for example the conveying mechanism complex structure, probability of failure certainly will be bigger; Car body is tediously long, and the flexibility of cause walking, turning round, turning around etc. is influenced, and the road occupying coefficient is big, and safety factor is low.

Shortcoming and for example: the B) road sweeper of Tui Jianing, though can eliminate A), it will be by means of the supporting use of dust exhaust apparatus, and is stronger to the fastidious property of rubbish, and occurs sweep-up pipe (patent claims air inlet duct) easily and stop up; This patent does not adopt rotary broom, by the dish type broom rubbish is driven to the dust exhaust apparatus place, so sweeping efficiency, effect are low.

Also as: C) Jiao Dao structure that road sweeper embodies more particularly its dish type broom (patent claim sideway swivel brush), rotary broom (patent claim to clean roll) transmission device still belong to the CN2484349Y category.
