Description

Technical Field

[0001] The present invention relates to the field of cleaning technology, and particularly to a main brush lifting mechanism. Background Art

[0002] Currently, in road surface cleaning, cleaning brushes are used to clean the road surface. For the cleaning brushes installed at the bottom of cleaning vehicles, once the ground is bumpy or has hard protrusions, the entire cleaning brush will jump and displace, resulting in damage to the cleaning brush mechanism. Currently, the general adjustment for the above problems with cleaning brushes is to use a flexible structure to connect both sides of the main brush. However, the flexible structure connection will result in insufficient structural stability. During operation, due to road surface bumps, the position of the cleaning brush will move and cannot be restored, affecting the subsequent cleaning effect. At the same time, the shaking of the cleaning brush during operation will affect work efficiency and product stability. For example, the disclosed patent 202011024891.6 discloses a floor sweeping robot, which connects the flexible side brush steel wire rope to the output end of the side brush cylinder to solve the buffering problem under bumpy road conditions. However, using a steel wire rope for connection results in insufficient product stability and affects the overall cleaning effect of the cleaning brush. Therefore, it is particularly important to solve the problems that the flexible structure connection of the cleaning brush of the road sweeper will lead to insufficient structural stability and a decline in cleaning effect. Summary of the Invention

[0003] The purpose of the present invention is to provide a main brush lifting mechanism. Through a hard connection method, the structural stability can be effectively guaranteed. At the same time, the lifting plate is designed with waist-shaped holes, which can effectively prevent the damage of the entire set of mechanisms caused by the vehicle passing through uneven roads. And the mechanism is equipped with a gas spring, which can effectively prevent the shaking phenomenon of the main brush during the working state, solving the problems that the flexible structure connection of the cleaning brush of the road sweeper will lead to insufficient structural stability and a decline in cleaning effect.

[0004] The present invention provides a main brush lifting mechanism, including a chassis. On both sides of the chassis, there are a main brush left stand and a main brush right stand. Between the main brush left stand and the main brush right stand, there is a main brush. On the chassis, there is a main brush disassembly plate. On the main brush disassembly plate, there is a main brush adjusting rod. Beside the main brush, there is a main brush motor. The main brush motor and the main brush are driven by a belt. On the base, there is a main brush adapter plate. Between the main brush left stand and the main brush adapter plate, there is a lifting plate. On the main brush adapter plate, there is an electric push rod. One end of the electric push rod is connected to the main brush adapter plate, and the other end is connected to the base.

[0005] Further improvement lies in that: on the chassis, there are stable bearings. The number of the stable bearings is two and they are respectively arranged on the left and right sides of the chassis. Between the stable bearings, there is a main brush balance rod.

[0006] A further improvement lies in that: a main brush small sprocket is arranged on the main brush motor, a main brush large sprocket is arranged on the main brush, and the belt transmits the power of the main brush motor to the main brush by connecting the main brush small sprocket and the main brush large sprocket.

[0007] A further improvement lies in that: a tension wheel is arranged on the left side stand of the main brush.

[0008] A further improvement lies in that: a gas spring is arranged between the chassis and the left side stand of the main brush to reduce the vibration of the main brush during operation through the gas spring.

[0009] A further improvement lies in that: the lifting plate is designed with waist-shaped holes to buffer the whole mechanism during bumpy driving through the lifting plate.

[0010] The beneficial effects of the present invention are as follows: This structure can effectively ensure the stability of the structure through a hard connection method. At the same time, through the waist-shaped hole design of the lifting plate, it can effectively prevent the damage of the whole set of mechanism caused by the vehicle passing through uneven roads. And the mechanism is equipped with a gas spring, which can effectively prevent the vibration of the main brush during the working state; the mechanism connects the right side stand and the left side stand of the main brush through the main brush balance rod. While ensuring the synchronous lifting and lowering of the main brush, it can simplify the mechanism, reduce costs, and pass the main brush balance rod through two stable bearings fixed on the chassis, which can also prevent the main brush balance rod from being deformed due to collision, thereby causing damage to the structure; both sides below the main brush are equipped with main brush adjusting rods, which can make the mechanism accurately adjusted on different grounds, thereby preventing the excessive consumption of the main brush or the situation that the ground cannot be cleaned thoroughly.

DETAILED DESCRIPTION OF THE INVENTION

[0016] To deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0017] As Figures 1-4 shown, this embodiment provides a main brush lifting mechanism, which includes a chassis 1. On both sides of the chassis 1, there are a main brush left stand 2 and a main brush right stand 3. Between the main brush left stand 2 and the main brush right stand 3, there is a main brush 4. On the chassis 1, there is a main brush removal plate 5. On the main brush removal plate 5, there is a main brush adjustment rod 6. Beside the main brush 4, there is a main brush motor 7. The main brush motor 7 and the main brush 4 are driven by a belt 8. On the base 1, there is a main brush adapter plate 9. Between the main brush left stand 2 and the main brush adapter plate 9, there is a lifting plate 10. On the main brush adapter plate 9, there is an electric push rod 11. One end of the electric push rod 11 is connected to the main brush adapter plate 9, and the other end is connected to the base 1. On the chassis 1, there are stable bearings 12. The number of stable bearings 12 is two and they are respectively arranged on the left and right sides of the chassis 1. Between the stable bearings 12, there is a main brush balance rod 13. On the main brush motor 7, there is a main brush small sprocket 14. On the main brush 4, there is a main brush large sprocket 15. The belt 8 transmits the power of the main brush motor 7 to the main brush 4 by connecting the main brush small sprocket 14 and the main brush large sprocket 15. On the main brush left stand 2, there is a tension pulley 16. Between the chassis 1 and the main brush left stand 2, there is a gas spring 17 to reduce the vibration of the main brush 4 during operation. The lifting plate 10 is designed with waist-shaped holes to buffer the entire mechanism during bumpy conditions.

[0018] Installation method: First, fix the main brush right stand 3, the main brush motor 7, the stable bearings 12, and the main brush left stand 2 on the chassis 1 in sequence. Then, fix both ends of the main brush 4 and the main brush balance rod 13 on the main brush right stand 3 and the main brush left stand 2 respectively. Fix the main brush adjustment rod 6 on the main brush removal plate 5, and then fix the main brush removal plate 5 on the chassis 1. Fix both ends of the gas spring 17 on the chassis 1 and the main brush left stand 2 respectively. Then, fix the main brush small sprocket 14 on the main brush motor 7, fix the main brush large sprocket 15 on the main brush 4, fix the belt 8 on the main brush large sprocket 15 and the main brush small sprocket 14, and then fix the tension pulley 16 on the main brush left stand 2. Fix both ends of the lifting plate 10 on the main brush left stand 2 and the main brush adapter plate 9 respectively. Finally, fix the main brush adapter plate 9 on the electric push rod 11 and the chassis 1 respectively. Thus, the installation of the entire main brush lifting mechanism is completed.

[0019] Embodiment: The operator turns on the control switch of the electric push rod 11, and the electric push rod 11 contracts, thereby driving the main brush adapter plate 9 to rotate around the fixed point on the chassis 1, causing the lifting plate 10 to descend, and further enabling the left main brush support 2 to drive the main brush 4 to gradually approach the ground. At the same time, through the main brush balance rod 13, the right main brush support 3 is driven to descend synchronously with the left main brush support 2 and contact the main brush adjusting rod 6, so as to achieve the ideal working state of the main brush 4; then the power switch of the main brush motor 7 is turned on, and the main brush motor 7 starts to drive the main brush small sprocket 14 to work, and then drives the main brush large sprocket 15 to work through the belt 8, thereby enabling the main brush to work.
