Description

Technical Field

[0001] This utility model relates to a sweeping component, specifically a lifting sweeping component for cleaning the floor. Background Technology

[0002] A sweeping assembly is a sweeping structure installed on a sweeper. It generally includes a housing that is upside down on the ground, a roller shaft inside the housing, a motor that drives the roller shaft to rotate at the end of the roller shaft, and a brush on the outer periphery of the roller shaft. When the motor drives the roller shaft to rotate, the brush cleans the ground.

[0003] However, as usage time increases, the brushes wear down and shorten, significantly reducing their cleaning effectiveness and requiring replacement. This results in low brush utilization. Furthermore, different environments require different brush lengths; for example, adjusting the brush's contact length with different types of debris on the floor can improve cleaning, necessitating brush replacement with different lengths. However, replacing brushes on the roller is time-consuming, labor-intensive, and costly. Utility Model Content

[0004] The main purpose of this utility model is to provide a lifting sweeping component to solve the problems of low brush utilization, time-consuming and laborious brush replacement, and high cost in the existing sweeping components.

[0005] This utility model provides a lifting sweeping assembly, including an inverted housing. A roller shaft is disposed within the housing, and a brush is mounted on the roller shaft. Symmetrical strip-shaped holes are provided on both sides of the housing. A movable plate is disposed within each strip-shaped hole and moves vertically along the hole. A rotation driver is mounted on the movable plate, and the rotation driver is connected to the roller shaft and drives the roller shaft to rotate. A lifting device is connected to the movable plate, which drives the movable plate to move vertically along the strip-shaped holes.

[0006] Preferably, U-shaped grooves are provided on the front and rear sides of the strip hole, and pulleys are provided on the front and rear sides of the movable plate. The pulleys are engaged in the U-shaped grooves and roll up and down in the U-shaped grooves.

[0007] Preferably, the lifter is connected to a rotary drive device located on the housing. The rotary drive device includes a rotating shaft, and the rotating shaft is connected to a motor that drives the rotating shaft to rotate. The rotating shaft extends toward the lifter and drives the lifter to move the movable plate up and down.

[0008] More preferably, the housing is provided with a rotating positioning seat, the rotating positioning seat is provided with a rotating hole, and the rotating shaft passes through the rotating hole.

[0009] Preferably, the two ends of the rotating shaft are respectively connected to the lifting devices on both sides.

[0010] Preferably, the lifting device is a lead screw jack, and the rotating shaft is inserted into and adapted to the lead screw jack.

[0011] Preferably, the strip-shaped hole extends obliquely from bottom to top and then backward.

[0012] Preferably, the housing includes a fixed housing at the rear and a rotating housing at the front. The rotating housing is rotatably connected to the fixed housing via a hinge, and the strip hole is provided on the fixed housing. The housing is also provided with a telescopic device, one end of which is connected to the fixed housing, and the other end of which is connected to the rotating housing. When the telescopic device extends or retracts, it causes the rotating housing to rotate about the hinge connection point as an axis.

[0013] The lifting sweeping component provided by this utility model has the following advantages compared with the prior art:

[0014] This invention provides a lifting sweeping assembly. The roller shaft and its drive mechanism move up and down along a slotted hole with a moving plate, thereby adjusting the distance between the roller shaft and the ground, and consequently, the grounding position of the brush. Operators can adjust the roller shaft height as needed, thus adjusting the brush grounding length. This lifting sweeping assembly allows for direct adjustment of the roller shaft height based on brush wear or the nature of the debris being swept, improving the flexibility of the sweeping assembly and increasing brush utilization.

[0026] Example 1

[0027] This embodiment provides a lifting sweeping assembly, including an inverted housing 8. A roller 7 is disposed within the housing 8, and a brush is mounted on the roller 7. Symmetrical strip-shaped holes are provided on both sides of the housing 8. A movable plate 4, moving vertically along the strip-shaped holes, is disposed within each hole. A rotation driver is mounted on the movable plate 4, connecting to and driving the roller 7 to rotate. The rotation driver and roller 7 can adopt the style of a conventional sweeping assembly, i.e., connected to the roller 7 via a motor 10. The difference is that the roller 7 and motor 10 are not directly fixed to the housing 8, but rather fixed to the movable plate 4. A lifting device 6 is connected to the movable plate 4, driving it to move vertically along the strip-shaped holes.

[0028] This embodiment provides a lifting sweeping assembly. The roller shaft 7 and its driving actuator move up and down along the slotted hole with the moving plate 4, thereby adjusting the distance of the roller shaft 7 from the ground and consequently the grounding condition of the brush. Operators can adjust the height of the roller shaft 7 as needed, adjusting the brush grounding length. This lifting sweeping assembly allows direct adjustment of the roller shaft 7 height based on brush wear or the nature of the debris being swept, improving the flexibility of the sweeping assembly and increasing brush utilization. Adjusting the brush grounding length to adapt to different working conditions also improves the cleaning effect. Furthermore, it should be noted that two slotted holes and two moving plates 4 are provided, symmetrically arranged on both sides of the housing 8. In this embodiment, only one moving plate 4 needs a driving actuator, typically a motor 10, while the other moving plate 4 only needs to have the roller shaft 7 rotated.

[0029] Specifically, in this embodiment, in order to control the movement trajectory of the moving plate 4 and avoid the moving plate 4 from deviating to the side, U-shaped grooves 11 are respectively provided on the front and rear sides of the strip hole, and pulleys 5 are provided on the front and rear sides of the moving plate 4. The pulleys 5 are inserted into the U-shaped grooves 11 and roll up and down in the U-shaped grooves 11.

[0030] More specifically, in this embodiment, the lifting device 6 is connected to a rotary drive device located on the housing 8. The rotary drive device includes a rotating shaft 9. To prevent the rotating shaft 9 from deflecting to the side, a rotating positioning seat can also be provided on the housing 8. The rotating positioning seat has a rotating hole through which the rotating shaft 9 passes. It should be noted that the rotating positioning seat is not a necessary structure. The rotating shaft 9 is connected to a motor 10 that drives the rotating shaft 9 to rotate. The rotating shaft 9 extends towards the lifting device 6 and drives the lifting device 6 to move the moving plate 4 up and down. With the above arrangement, the two ends of the rotating shaft 9 can be inserted into the lifting devices 6 on both sides respectively. One motor 10 can drive one rotating shaft 9 to rotate, and thus one rotating shaft 9 can synchronously drive the lifting devices 6 on both sides to work synchronously. This not only saves the number of motors 10, but also enables the lifting devices 6 on both sides to work synchronously, avoiding jamming caused by the lifting devices 6 being out of sync.

[0031] More specifically, in this embodiment, the lifting device 6 is a lead screw lifting device 6, and the rotating shaft 9 is inserted into the lead screw lifting device 6 and adapted to the lead screw lifting device 6.

[0032] Specifically, in this embodiment, the strip-shaped hole extends obliquely from bottom to top and backward.

[0033] Specifically, in this embodiment, the housing 8 includes a fixed housing 81 located at the rear and a rotating housing 82 located at the front. The rotating housing 82 is rotatably connected to the fixed housing 81 via a hinge, and the strip-shaped hole is provided on the fixed housing 81. The housing 8 is also provided with a telescopic device 3, one end of which is connected to the fixed housing 81, and the other end of which is connected to the rotating housing 82. When the telescopic device 3 extends or retracts, it causes the rotating housing 82 to rotate around the hinge connection point. With the above arrangement, the rotating housing 82 at the front can be opened to increase the air intake of the housing 8, and it also facilitates the maintenance of the various mechanisms inside the housing 8.

[0034] Of course, the above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model and should be protected by the present utility model.
