Detailed ways

The composition of the hand-push sweeper in this example includes:

As shown in Figure 1, the roller brush 1, the hub motor 2, the steel wire 3, the arc-shaped transition plate 4, the conveyor belt 5, the universal wheel 6, the small sprocket 7, the chain 8, the large sprocket 9, and the collection box 10 , battery 11 , press handle 12 , speed control handle 13 .

The roller-shaped brush 1 is arranged at the rear of the cart, and its rotational speed is 60-150 r/min; the battery 11 supplies power to the hub motor 2 to drive the roller-shaped brush 1 to rotate, and its rotational speed can be adjusted by twisting the handle 13 . An arc-shaped transition plate 4 is installed under the roller-shaped brush 1. When the roller-shaped brush 1 is in contact with the ground, one side of the transition plate 4 is in contact with the ground at the same time. The rotating shaft of 1 is connected to control its relative position with the roller brush 1, so that the arc-shaped transition plate 4 has a buffer displacement upward, and the arc-shaped transition plate 4 will not be damaged when obstacles such as stones appear on the road. The other side of the arc-shaped transition plate 4 is connected to a rotating shaft of the frame, and keeps as small a gap as possible with one end of the conveyor belt 5. The diameter of the rotating shaft of the conveyor belt 5 at this end is 20 mm. The other end of the conveyor belt 5 extends into the collection box 10, the chain 8 connects the small sprocket 7 and the large sprocket 9, the small sprocket 7 is fixed on the rotating shaft of the conveyor belt 5, and the large sprocket 9 is fixed on the rotating shaft of the front wheel of the trolley. When the wheel rotates, it will drive the large sprocket 9, the chain 8, and the small sprocket 7 to move in turn, thereby driving the conveyor belt 5 to run. The push handle 12 is located in the middle of the hand-held support frame and the bottom support frame, and is connected with the universal wheel 6 through a rod structure. Pressing the handle can adjust the relative height between the universal wheel 6 and the support frame; When cleaning, move the handle 12 up, the roller-shaped brush 1 and the arc-shaped transition plate 4 will be separated from the ground. When cleaning the ground, press the handle, and the roller-shaped brush 1 and the arc-shaped transition plate 4 are in close contact ground.

As shown in Figure 2, when cleaning, the roller brush 1 rotates rapidly counterclockwise, and with the aid of the arc-shaped transition plate 4, the garbage is swept onto the conveyor belt 5. At the same time, the front wheel of the cart rotates clockwise to drive the large sprocket 9, The chain 8 and the small sprocket 7 rotate clockwise, and finally drive the conveyor belt 5 to rotate to transport the garbage into the collection box 10 .

As shown in Figure 3, the rubber skin 1a covered with bristles on the surface is bonded to the cylindrical plastic shell 1b by a hook and loop tape, and the bristles on the surface can effectively adhere to the garbage. After the bristles are damaged, only the rubber skin 1a needs to be replaced.

As shown in FIG. 4 , the collection box is composed of a box body 10a, a door panel 10b and a brush 10c, wherein the brush 10c is close to the conveyor belt 5 inside the collection box 10, and can sweep the garbage adhering to the conveyor belt and fall into the collection box. The door panel 10b is on the surface of the collection box and on the lower side of the conveyor belt 5. When the collection box is full, remove it, open the door panel, and pour out the garbage.

The working process of the hand-push sweeper is as follows: the battery supplies power to the hub motor, which drives the roller-shaped brush to rotate, and its speed can be adjusted by the speed control handle. Close to the ground, push the sweeper to move at this time, the front wheel rotates, which in turn drives the large sprocket, the chain and the small sprocket rotate clockwise. The conveying of the conveyor belt is collected by the scraping of the brush into the collecting box. In the working state, the roller-shaped brush is close to the ground, and when it rotates, the cleaning force is large, and the cleaning effect is better on the slippery ground with garbage or the ground with a certain amount of water. When the cleaning work is over, move the handle up, and the roller-shaped brush will be off the ground to reduce unnecessary wear and tear. The utility model has the characteristics of low energy consumption, high cleaning efficiency and wide adaptability to the road surface.
