Abstract

The utility model discloses a foldable broom which is characterized in that one end of each mechanical arm is connected with a rotating plate; a pin penetrates into a pin hole in the middle of each rotating plate; the rotating plates are mounted on rotating supports on vehicle beams on two sides in the front of a hand-pushed road sweeper; the other end of each mechanical arm is connected with a rotating shaft sleeve; a handle is arranged outside each rotating shaft sleeve; a rotating shaft is sleeved in each rotating shaft; threads are formed at two ends of each rotating shaft; the upper ends of the rotating shafts penetrate into holes in the middles of belt pulleys, and then nuts are screwed at the tail ends of the upper ends; and after the lower ends of the rotating shafts penetrate into holes in the middles of sweep plates, the nuts are screwed at the tail ends of the lower ends. The handles outside the rotating shaft sleeves are pulled, and all the components (including the rotating shaft sleeves, the rotating shafts in the rotating shaft sleeves, the belt pulleys at the upper ends of the rotating shafts, and the sweep plates at the lower ends of the rotating shafts) on the mechanical arms at the ends connected with the rotating shaft sleeves conduct arc ascending movement around the pins on the rotating supports and draw close to the middle of a vehicle body until to reach the highest points, so that the operation of folding the broom is finished; and the folded broom provides convenience for moving and parking the hand-pushed road sweeper which finishes the sweeping operation.

Description

Folding broom

Affiliated technical field

The utility model relates to a kind of mechanical part of hand push road sweeper.

Background technology

The round broom of everybody employed hand push road sweeper front is to be fixed on the machine shaft sweeping dish at present, and motor is fixed on the car body.When the hand push road sweeper does not use, when moving, need push down car body; Relying on the wheel of design in the middle of underneath its body is that fulcrum makes the car body front, comprises that the parts of sweeping dish are liftoff, moves very inconvenient; When parking; Because it is wideer than car body that broom is swept dish, need the very big distance of maintenance, so it is big to take up room.

Summary of the invention

In order to overcome the big shortcoming that takes up room when existing hand push road sweeper moves inconvenience and parks; The utility model provides a kind of folding broom; Hand push road sweeper convenient moving when not using should be folding broom not only can let, and hand push road sweeper shared space when parking can also be reduced.

The utility model solves the technical scheme that its technical problem adopted: folding broom comprises, the dish of sweeping that rotating stand, mechanical arm, centre have the rolling disc of pin-and-hole, the threaded rotating shaft in rotating shaft cover, two ends that there is handle the outside, middle porose belt pulley and middle porose outside to be implanted with some broom silks.End at mechanical arm is connected with rolling disc, and a pin penetrates in the pin-and-hole in the middle of the rolling disc, and rolling disc is installed on the rotating stand that is fixed on the two sidecar beams of hand push road sweeper front; The other end at mechanical arm is connected with the rotating shaft cover, in the rotating shaft cover rotating shaft is arranged, and the rotating shaft upper end has nut to be screwed in end after penetrating the hole in the middle of the belt pulley; The rotating shaft lower end has nut to be screwed in end after penetrating and sweeping the middle hole of dish.Upwards pull the outer handle of rotating shaft cover; That end that mechanical arm is connected rotating shaft cover comprises that all rotate pin on the moving bearing of the parts of sweeping dish of belt pulley and the rotating shaft lower end of rotating shaft in rotating shaft cover, the rotating shaft cover, rotating shaft upper end makes camber line and rise and in the middle of car body, draw close; Up to the folding operation that rises to the just intact broom of peak, the broom after folding can make the hand push road sweeper that finishes cleaning work conveniently move and park.On the contrary; Pull the outer handle of rotating shaft cover downwards; That end that mechanical arm is connected rotating shaft cover comprises that all rotate pin on the moving bearing of the parts of sweeping dish of belt pulley and the rotating shaft lower end of rotating shaft in rotating shaft cover, the rotating shaft cover, rotating shaft upper end makes camber line and descend; Up to contacting, carry out cleaning work with ground.

The beneficial effect of the utility model is; Under the prerequisite that does not influence the normal cleaning work of hand push road sweeper; Occupation space when conveniently moving and minimizing are parked after can also making the hand push road sweeper finish to clean; In link, designed rotating stand, rolling disc and mechanical arm, its reasonable in design, simple to operate.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is the folding preceding front section view of folding broom

Fig. 2 is the front section view of folding broom folding back embodiment

Among Fig. 1: 1 car beam, 2 rotating stands, 3 mechanical arms, 4 rolling discs, 5 handles, 6 rotating shaft covers, 7 rotating shafts, 8 belt pulleys, 9 are swept dish.

The specific embodiment

In Fig. 1, the rolling disc (4) of pin-and-hole in the middle of being connected with, an end of mechanical arm (3) is arranged, and a pin penetrates in the pin-and-hole in the middle of the rolling disc (4), and rolling disc (4) is installed on the rotating stand (2) that is fixed on the two sidecar beams (1) of hand push road sweeper front; The other end at mechanical arm (3) is connected with the rotating shaft cover (6) that there is handle (5) outside, is the threaded rotating shafts in two ends (7) in the rotating shaft cover (6), and rotating shaft (7) upper end has nut to be screwed in end after penetrating the hole in the middle of the belt pulley (8); Rotating shaft (7) lower end has nut to be screwed in end after penetrating and sweeping the middle hole of dish (9).，

In embodiment illustrated in fig. 2: upwards pull the handle (5) outside the rotating shaft cover (6); That end that mechanical arm (3) is connected rotating shaft cover (6) comprises that all rotate pin on the moving bearing (2) of the parts of sweeping dish (9) of belt pulley (8) and rotating shaft (7) lower end of rotating shaft (7) in rotating shaft cover (6), the rotating shaft cover (6), rotating shaft (7) upper end makes camber line and rise and in the middle of car body, draw close, up to rising to the folding operation that peak just finishes broom.On the contrary; Pull the outer handle (5) of rotating shaft cover (6) downwards; That end that mechanical arm (3) is connected rotating shaft cover (6) comprises that the pin that the parts of sweeping dish (9) of belt pulley (8) and rotating shaft (7) lower end of rotating shaft (7) in rotating shaft cover (6), the rotating shaft cover (6), rotating shaft (7) upper end all rotate on the moving bearing (2) does camber line decline; Up to contacting, carry out cleaning work with ground.
