Description

Technical Field

[0001] This invention belongs to the technical field of road sweeping equipment, specifically relating to a floating roller brush suction cup and its working method, and a sweeper vehicle. Background Technology

[0002] Currently, most road sweeper trucks have a roller brush installed behind the air duct opening of the suction nozzle to improve the cleaning effect of road debris. As one of the key components of the suction nozzle, the roller brush plays a decisive role in the cleaning effect. During cleaning operations, the roller brush needs to descend to contact the ground, maintaining a certain contact distance between the brush bristles and the ground to form a rectangular cleaning area, thus ensuring effective cleaning. Therefore, the contact area and contact force between the suction nozzle roller brush and the ground determine the cleaning effect of the suction nozzle.

[0003] The existing solution uses a cylinder to extend and retract, automatically adjusting the roller brush's ground clearance. The roller brush is rotatably connected to rotating frames on both sides of the suction cup via connecting shafts at both ends. The cylinder's extension and retraction rotates these frames, controlling the roller brush's descent. The rotating frames and their associated cylinders are independently mounted on the side plates of the suction cup. Due to the large gap between the suction cup side plates, it's difficult to ensure coaxiality at the hinge points of the rotating frames on both sides. Furthermore, when the cylinders on both sides are out of sync, the roller brush can easily become skewed or twisted, affecting its lifespan and cleaning effectiveness.

[0004] Therefore, the related technology has the technical problem that the independent rotating frame scheme can easily lead to the skew and twisting of the roller brush. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a floating roller brush suction cup, its working method and a sweeper, which aims to adjust the height of the roller brush by rotating it around an axis, thereby ensuring the coaxiality and structural stability of the roller brush.

[0006] To achieve the above objectives, the present invention is implemented using the following technical solution: In a first aspect, the present invention provides a floating roller brush suction cup, comprising: Suction cup body; A roller brush mechanism is movably mounted on the suction cup body; the roller brush mechanism is provided with a rotatable rotating shaft, the two ends of which are respectively hinged to the suction cup body; An air duct component is disposed on the suction cup body and located on one side of the roller brush mechanism; The telescopic mechanism has its two ends connected to the suction cup body and the roller brush mechanism, respectively. When the telescopic mechanism extends or retracts, it can drive the roller brush mechanism to rotate around the rotating shaft.

[0007] Furthermore, the roller brush mechanism is provided with a telescopic mechanism connecting plate; The suction cup body is provided with a hinge seat; The telescopic mechanism is connected to a telescopic mechanism connecting plate and a hinge seat at both ends.

[0008] Furthermore, the roller brush mechanism includes: The roller brush cover is equipped with the telescopic mechanism connecting plate; A roller brush is rotatably mounted on the roller brush cover via connecting shafts at both ends, the connecting shafts being connected to a sprocket; A motor is mounted on the roller brush cover, and the motor drive is connected to another sprocket. The two sprockets are connected by a chain drive. A rotating shaft is rotatably mounted on the roller brush cover, and the two ends of the rotating shaft are respectively hinged to both sides of the suction cup body.

[0009] Furthermore, rotating seats are provided on both sides of the suction cup body, and the rotating shaft is hinged to the rotating seats; The side sealing plate is disposed on the outer side of the rotating seat, and the side sealing plate is provided with a guide hole; the connecting shaft passes through the guide hole and is movably connected to the side sealing plate.

[0010] Furthermore, the roller brush includes a spindle, bristles evenly arranged on the spindle, and connecting shafts disposed at both ends of the spindle.

[0011] Furthermore, a front rubber plate that fits against the rotating shaft is provided on the front side of the roller brush; The roller brush is provided with a rear baffle and a rear rubber plate that extends from the roller brush cover to the rear baffle and fits against the rear baffle. The front and rear rubber plates are used to form a closed space on the upper side of the roller brush.

[0012] Furthermore, the suction cup body is equipped with multiple wheels to support the suction cup body.

[0013] Furthermore, the air duct component includes: Corrugated pipe; A suction port, which is detachably connected to the lower end of the bellows; The water spray pipe has one end connected to the internal space of the suction port and the other end connected to the water inlet connector, and is used to spray water into the suction port.

[0014] Secondly, the present invention provides a sweeper vehicle, wherein the sweeper vehicle is equipped with any of the above-mentioned floating roller brush suction cups.

[0015] Thirdly, the present invention provides a method for operating a floating roller brush suction cup, applicable to any of the floating roller brush suction cups described above, comprising the following steps: When carrying out road sweeping operations, activate the roller brush mechanism and air duct components; The roller brush mechanism rolls road debris to the area below the air duct component, which then captures the debris by drawing in airflow. When the roller brush encounters a raised obstacle on the road surface, the extension mechanism drives the roller brush mechanism to rotate around the rotating axis, thereby adjusting the height of the roller brush and allowing it to float up and down with the uneven ground.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: This invention provides a floating roller brush suction cup. By setting a rotatable rotating shaft in the roller brush mechanism, with both ends of the rotating shaft hinged to the suction cup body, the roller brush mechanism can be driven by a telescopic mechanism to rotate around the rotating shaft. The roller brush mechanism can achieve height adjustment by rotating to adapt to different usage environments.

[0017] This invention provides a floating roller brush suction cup. Since the rotation center is the rotating shaft, the entire roller brush mechanism can rotate synchronously up and down around the rotating shaft. Even if the left and right telescopic cylinders are not synchronized, the roller brush mechanism can always maintain synchronous movement, thereby avoiding the phenomenon of roller brush tilting or twisting.

[0020] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0021] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] Please see Figure 1 , Figure 2 and Figure 3 This embodiment describes a floating roller brush suction cup, including an air duct component 1, a suction cup body 6, a roller brush mechanism 8, and a telescopic mechanism.

[0025] Please refer to Figure 1 The roller brush mechanism 8 is movably mounted on the suction cup body 6; the roller brush mechanism 8 is provided with a rotatable rotating shaft 8-2, and the two ends of the rotating shaft 8-2 are respectively hinged to the suction cup body 6; the air duct component 1 is provided on the suction cup body 6 and located on one side of the roller brush mechanism 8; the two ends of the telescopic mechanism are respectively connected to the suction cup body 6 and the roller brush mechanism 8, and the telescopic mechanism can drive the roller brush mechanism 8 to rotate around the rotating shaft 8-2 when it is telescopic.

[0026] In the above technical solution, the roller brush mechanism 8 can be height adjusted by rotation to adapt to different usage environments. Since the rotation center is the rotating shaft 8-2, the entire roller brush mechanism 8 can rotate synchronously up and down around the rotating shaft 8-2. Even if the left and right extension mechanisms are not synchronized, the roller brush mechanism 8 can always maintain synchronous movement based on the overall consistency of the rotating shaft 8-2, thereby avoiding the phenomenon of roller brush tilting or twisting.

[0027] Specifically, please refer to Figure 1 The telescopic mechanism 5 uses telescopic cylinders, and there are two telescopic cylinders, symmetrically arranged on the left and right sides. The roller brush mechanism 8 is equipped with two telescopic mechanism connecting plates 8-3; the suction cup body 6 is equipped with two hinge seats 7, each corresponding to one of the two telescopic cylinders; the two ends of the telescopic cylinders are respectively hinged to the corresponding telescopic mechanism connecting plate 8-3 and hinge seat 7. While the telescopic cylinders extend and retract, they drive the roller brush mechanism 8 to rotate around the rotation axis 8-2 as the center.

[0028] For example, please refer to Figure 5The roller brush mechanism 8 includes a roller brush 8-1, a rotating shaft 8-2, a roller brush cover 8-6, and a motor 8-8. The roller brush cover 8-6 is equipped with a telescopic mechanism connecting plate 8-3. The roller brush 8-1 is rotatably mounted on the roller brush cover 8-6 via connecting shafts 8-1-3 at both ends, and each connecting shaft 8-1-3 is connected to a sprocket 8-5. The motor 8-8 is located on the roller brush cover 8-6 and is driven by another sprocket 8-5. The two sprockets 8-5 are connected by a chain 8-4. The rotating shaft 8-2 is rotatably mounted on the roller brush cover 8-6, and its two ends are hinged to both sides of the suction cup body 6. The rotating shaft 8-2 is machined from a single piece to ensure coaxiality during assembly of the roller brush mechanism 8 and prevent left-right offset during rotation. The roller brush 8-1 includes a spindle 8-1-1, bristles 8-1-2 evenly arranged on the spindle 8-1-1, and connecting shafts 8-1-3 set at both ends of the spindle 8-1-1; the connecting shafts 8-1-3 pass through the guide hole 3-1 and are movably connected to the suction cup body 6; the bristles 8-1-2 can be made of materials such as nylon or steel wire.

[0029] During operation, the motors 8-8 on the left and right sides drive the sprockets 8-5 on the same side to rotate, thereby driving the sprockets 8-5 and the connecting shaft 8-1-3 connected to the roller brush 8-1 to rotate synchronously through the chain 8-4, so that the roller brush 8-1 rotates to clean the ground.

[0030] The roller brush cover 8-6 is equipped with an observation port 8-7. The observation port 8-7 is used for maintenance of the roller brush 8-1.

[0031] Further, please refer to Figure 1 The suction cup body 6 has rotating seats 4 on both sides, and the rotating shaft 8-2 is hinged to the rotating seats 4. The side sealing plate 3 is set on the outer side of the rotating seat 4, and the side sealing plate 3 is provided with a guide hole 3-1. The connecting shaft 8-1-3 passes through the guide hole 3-1 and is movably connected to the side sealing plate 3. The guide hole 3-1 is an arc-shaped elongated hole with a radius from the rotation center of the rotating seat 4 to the center of the roller brush 8-1, so that the roller brush 8-1 can rotate along the arc-shaped elongated hole when working.

[0032] Please see Figure 3 In order to form a closed space on the upper side of the roller brush 8-1, a front rubber plate 12 that fits against the rotating shaft 8-2 is provided on the front side of the roller brush 8-1; a rear baffle 16 and a rear rubber plate 14 that extends from the roller brush cover 8-6 to the rear baffle 16 and fits against the rear baffle 16 are provided on the rear side of the roller brush 8-1; the front rubber plate 12 and the rear rubber plate 14 are used to form a closed space on the upper side of the roller brush 8-1.

[0033] Please see Figure 4The air duct component 1 includes a corrugated pipe 1-1, a suction port 1-6, and a water spray pipe 1-4. The suction port 1-6 is detachably connected to the lower end of the corrugated pipe 1-1; the water spray pipe 1-4 has one end connected to the internal space of the suction port 1-6 and the other end connected to a water inlet connector, and is used to spray water into the suction port 1-6. The suction cup body 6 is provided with a limiting block 13 located between the roller brush mechanism 8 and the air duct component 1. A limiting bracket 15 is installed above the roller brush mechanism 8.

[0034] Depending on the required suction width, one or more air duct components 1 can be designed. Each air duct component 1 has a second rubber plate 10 at its bottom to guide the air intake direction of the suction ports 1-6 towards the side facing the roller brush mechanism 8. The second rubber plate 10 is installed inside the suction cup body 6, below the air duct component 1, and perpendicular to the ground, in a bowl shape that is wider at the front and narrower at the back. Four wheels 2 are installed on the front and rear sides of the suction cup body 6 to ensure that the suction cup body 6 is always kept at a certain distance from the ground during operation. The telescopic mechanism 5 is used to control the ground clearance of the roller brush mechanism 8.

[0035] Further, please refer to Figure 4 The corrugated pipe 1-1 is installed on the connecting seat 1-2 and connected to the pneumatic system of the sweeper. The gasket 1-3 is located between the connecting seat 1-2 and the suction port 1-6, serving to seal the gap at the connection between the connecting seat 1-2 and the suction port 1-6. The water spray pipe 1-4 is connected to the water inlet connector through a pipeline, spraying water into the suction port 1-6 to reduce dust and clear blockages. The latch 1-5 is used to tightly connect the connecting seat 1-2 and the suction port 1-6. When debris blocks the air duct component 1, the suction port 1-6 can be removed by loosening the latch 1-5 for cleaning without removing the corrugated pipe 1-1. In this embodiment, the suction port 1-6 is flared, wider at the bottom than the top.

[0036] Please refer to [link / reference needed] for further information. Figure 2 A first rubber plate 9 is installed at the front end of the suction cup body 6, angled forward at a 60°~90° angle to the ground. A third rubber plate 11 is located behind the second rubber plate 10, angled forward at a 30°~60° angle to the ground. These rubber plates serve to block dust from flowing out and act as guide plates, thereby ensuring the suction effect.

[0037] The following describes the content involved in the above embodiments with reference to specific examples.

[0038] Please see Figure 6 and Figure 7 For example, during suction cup operation, motor 8-8 drives sprocket 8-5 to rotate clockwise. Figure 6As shown by the arc arrow A, driven by the chain 8-4 and sprocket 8-5, the roller brush 8-1 rotates synchronously in front of the suction cup. When road debris enters below the suction port 1-6 from the front of the suction cup, most of the debris is captured by the suction airflow and transported into the debris bin. A small amount of debris that is missed is swept forward by the outer bristles 8-1-2 of the roller brush 8-1 and, guided by the slope of the third rubber plate 11, flies into the suction port 1-6, where it is then sucked up by the pneumatic system, completing the cleaning operation.

[0039] To ensure effective cleaning, the outermost bristles of the roller brush 8-1, at ends 8-1-2, must be firmly pressed against the ground, with each bristle end typically maintaining a contact length of 10mm ± 5mm, forming a rectangular cleaning area. For example... Figure 7 As shown, in order to achieve the contact length of the brush bristles 8-1-2 described above, this embodiment uses a telescopic mechanism 5 to retract (as shown in the image). Figure 7 The pulling force generated by the straight arrow B in the image pulls the roller brush mechanism 8 downward along the rotating seat (as shown by the arrow B in the image). Figure 7 As shown by the arc arrow C in the figure, under the balanced action of the tension of the telescopic mechanism 5 and the supporting force of the bristles 8-1-2, the bristles 8-1-2 always press firmly against the ground and maintain a reasonable contact length.

[0040] Please see Figure 8 and Figure 9 When the bristles 8-1-2 wear down and shorten, the roller brush mechanism 8 rotates downward under the pulling action of the telescopic mechanism 5, pressing the bristles 8-1-2 firmly against the ground and maintaining the distance between the roller brush 8-1 and the suction port 1-6 at all times, without manual intervention. Figure 9 The straight arrow E in the diagram indicates the pulling and retraction direction of the telescopic mechanism 5. Based on the pulling of the telescopic mechanism 5, the rotating shaft 8-2 can rotate clockwise accordingly (e.g., ...). Figure 8 (As shown by arrow D in the image), thus shifting the overall position of the roller brush 8-1 downwards.

[0041] Please see Figure 10 When the roller brush 8-1 encounters a raised obstacle 17 on the road surface, the roller brush 8-1 can float up and down with the uneven ground, thereby avoiding damage to the roller brush.

[0042] To ensure the suction cup's gripping capability, the suction airflow is typically only allowed to enter the suction cup from the four edges of its bottom. Therefore, to ensure the seal between the roller brush mechanism 8 and the suction cup body 6, the elastic deformation of the rubber plate itself is used during the up-and-down rotation of the roller brush mechanism 8 to keep the front rubber plate 12 and the rotating shaft 8-2, and the rear rubber plate 14 and the rear baffle 16 in a pressed and fitted state, preventing the suction airflow from overflowing.

[0043] Please see Figure 11 When the operation is completed, the telescopic mechanism 5 extends (e.g., Figure 11As indicated by the straight arrow F in the diagram, the telescopic mechanism 5 extends, and under the thrust generated by the telescopic mechanism 5, the roller brush mechanism 8 is retracted to the upper position. Through the thrust of the telescopic mechanism 5 and the limiting action of the upper limit frame 15, the roller brush mechanism 8 is kept fixed, preventing the roller brush mechanism 8 from swinging up and down during the transportation of the sweeper, and reducing the impact of the roller brush on the passage of the vehicle during driving.

[0044] Please see Figure 12 When the roller brush 8-1 wears to its limit, the edges of the two side plates of the roller brush cover 8-6 touch the limit block 13. The limit block 13 prevents the roller brush mechanism 8 from continuing to descend and causing it to collide with the ground and be damaged. At this time, the roller brush needs to be replaced.

[0045] Some embodiments also provide a floating roller brush suction cup, in which the roller brush 8-1 is driven to rotate by a direct connection between the motor 8-8 and the connecting shaft 8-1-3 of the roller brush 8-1.

[0046] Some embodiments also provide a floating roller brush suction cup, which can drive the roller brush 8-1 to rotate via a gear transmission of the connecting shaft 8-1-3 between the motor 8-8 and the roller brush 8-1.

[0047] Some embodiments also provide a sweeper equipped with the floating roller brush suction cup described in the above embodiments.

[0048] Some embodiments also provide a method for operating the floating roller brush suction cup, applicable to the floating roller brush suction cup in the above embodiments, including the following steps: When carrying out road sweeping operations, activate the roller brush mechanism 8 and the air duct component 1; The roller brush mechanism 8 rolls the road debris to the area below the air duct component 1, and the air duct component captures the road debris by sucking up airflow; When the roller brush encounters a raised obstacle 17 on the road surface, the roller brush mechanism 8 is driven by the telescopic mechanism 5 to rotate around the rotating shaft 8-2, so as to adjust the height of the roller brush of the roller brush mechanism 8 and thus float up and down with the uneven ground.

[0049] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and not to limit its protection scope. Although this disclosure has been described in detail with reference to the above embodiments, those skilled in the art should understand that after reading this disclosure, they can still make various changes, modifications or equivalent substitutions to the specific implementation of the invention, but these changes, modifications or equivalent substitutions are all within the protection scope of the pending claims.
