Abstract

The utility model relates to a road sweeping device which is a mechanical sweeping tool. The structure of the utility model is that a chain wheel driving mechanism is arranged on a three-wheel running mechanism. The transmission of a sprocket drives a deflector rod and a shifting fork to enable a positioning plate connected with the T-shaped rotating shaft of a vehicle frame to accomplish a facade elliptical motion track to enable a broom fixed on the lower side of the positioning plate to do actions similar to manual sweeping to accomplish mechanical sweeping. The utility model has the advantages of small volume and simple structure. The sweeping speed is improved more than three times, and the labor intensity of cleaners is alleviated.

Description

Highway sweeper

The utility model relates to a kind of street cleaning device, specifically a kind of mechanical cleaning device.

The street cleaning in present all kinds of cities mainly is to lean on manually to finish with besom, and labour intensity is big, and efficient is lower.At the seventies the report of small-sized electric cleaning car, this road-sweeper one being arranged once is to need provide electric power with storage battery, and use cost is higher; The 2nd, because of the use occasion dust is very big, easily be collected in the car body, clean or keep in repair car with regard to needing after use a period of time, cause the inconvenience of use, thereby also fail generally to be promoted.

The purpose of this utility model just provides a kind of mechanically operated clearing apparatus, to alleviate numerous sanitationman's labour intensity, increases work efficiency.

The utility model is achieved in that on a three-wheel walking mechanism chain wheel driving mechanism is installed, utilize chain gear transmission, drive a driving lever and shift fork, make the location-plate that joins with the rotating shaft of vehicle frame T shape realize a kind of movement locus of facade ellipse, thereby make the besom that is fixed on below the location-plate make the similar cleaning action of sweeping of manually waving, reach the purpose of machinery cleaning.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is a structural representation of the present utility model.

As shown in the figure, on the walking mechanism that constitutes by three wheels 2,8 and vehicle frame 7, be equipped with one with the synchronous sprocket wheel 4 of rotation of wheel, the sprocket wheel 9 that connects by axle in vehicle frame 7 front portions joins through chain 11 and sprocket wheel 4.One side of sprocket wheel 9 is fixed with bent plate 10, and an end of the front curvature of bended plate type 10 is porose, socket driving lever 12 in the hole.There is an axle sleeve to be socketed in horizontal axis one end of a T oblique crank Z 6, the location-plate 14 of the other end connecting band axle sleeve of this horizontal axis on the driving lever 12.The vertical axes of T oblique crank Z 6 is located by being socketed in the axle sleeve 6 that joins with vehicle frame 7 one ends.Also have shift fork 13 on the axle sleeve of driving lever 12, withstand under the plate face of location-plate 14.Porose on the location-plate 14, the fixed bar on the snap ring 15 of socket besom 11 passes location-plate 14, and screws the location by wing nut 17.

Because the wheel in the three-wheel walking mechanism has two kinds to be connected the method for operation with main shaft, thereby two kinds of different installation connected modes are just arranged with the synchronous sprocket wheel 4 that rotates of wheel.Fig. 1 provides is wheel and the motionless three-wheel walking mechanism of main shaft.Its concrete connected mode is that the wheel 2 in two same footpaths is paid the two ends that are connected main shaft 3 by bearing, and an end of vehicle frame 7 is welded on the main shaft 3.Sprocket wheel 4 is enclosed within on the main shaft, and fixedlys connected with the wheel hub of wheel 2 by securing member.Thereby guarantee the synchronous rotation of sprocket wheel 4 and wheel 2.

Second kind of three-wheel walking mechanism is the structure of similar available man-power tricycle, and promptly wheel rotates synchronously with main shaft.In this mechanism, two wheels 2 with the footpath are fixedly connected on the two ends of main shaft 3, and an end of vehicle frame 7 is welded on the bearing outer ring that is enclosed within on the main shaft 3, and sprocket wheel 4 is connected with main shaft 3 keys.Like this, sprocket wheel 4 can rotate with main shaft synchronously with wheel 2.

When the three-wheel walking mechanism travels forward, sprocket wheel 4 i.e. rotation synchronously thereupon, drive sprocket wheel 9 and bent plate 10 rotations by chain 11, make driving lever 12 movement therewith, at horizontally rotating under the synthesis that swings up and down with shift fork 13 of T oblique crank Z 6, the elliptic motion that makes the besom 16 that joins with location-plate 14 produce an in the vertical direction: cleaning ground when changeing down, lift during last commentaries on classics, and, then clean the ground of continuing last time when falling once more, thereby realized continuous cleaning because of installing whole advancing.

This device can be hooked on the tricycle that uses when existing environmental sanitation personnel clean Streets, and also can use separately.The form of using then needs to install a cart handle 1 on main shaft 3 or vehicle frame 7 separately, with artificial directly push-and-pull, provides the power that advances.In structure shown in Figure 1, two external parts of " Qian " shape handle 1 can be directly fixed on the main shaft 3; For the three-wheel walking mechanism of main shaft, then two external parts of handle 1 can be connected on the main shaft 3 by bearing with the wheel rotation.The handle 1 of this moment can relatively rotate, and also can adapt to the personnel's tractive or the promotion of differing heights.

Vehicle frame 7 in this device is a three-dimensional coordinate shape, and an end and main shaft join, and second termination fixedly axle sleeve 6, the three ends of T oblique crank Z is a preceding lower end chain link wheel 9.Also can replace big wheel with regard to an available minor diameter wheel like this, thereby reduce material cost in this end by axle connection wheel 8.

Location-plate 14 and besom are stable to be connected in order to make, in case occur slip phenomenon in the process repeatedly sweeping, front end that can location-plate 14 is bent down, downward bent part has an arc gap, and the handle end of besom stretches in the snap ring 15, and the rear portion is stuck in this gap, screw wing nut 17, can make besom firm.

This device also can be directly match with existing tricycle, is about to sprocket wheel 4 and directly is installed on behind the tricycle on the turning cylinder, and vehicle frame and three-wheel car body join, thereby still can realize the transmission of sprocket wheel, driving lever, makes shift fork drive location-plate and besom moves.When pedaling by tricycle, cleaned the street.

The utility model volume is little, and is simple in structure, and a people pushes away, draws walking to clean road and sidewalk clean.This device can improve more than the cleaning speed twice, and has alleviated sanitationman's labour intensity greatly.
