The suction cup device includes a plate body, a suction chamber, and rollers. The suction chamber and rollers are both set on the plate body. The suction chamber is located in the middle of the plate body and includes a front, rear, left, right, and top surface. The front is a rubber plate and also includes a connecting rod, a guide seat, a pin, and a cylinder. The guide seat is set at the front of the top surface of the suction chamber. The cylinder is hinged to the rear of the top surface of the suction chamber. The guide seat is provided with a guide groove. The pin is located in the guide groove. The piston rod of the cylinder is hinged to the pin. One end of the connecting rod is hinged to the pin, and the other end of the connecting rod is fixed to the upper end of the front rubber plate.

[0036] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0037] This application discloses a novel sweeping suction cup device for a sweeper truck. (Refer to...) Figure 1-2 The new type of sweeper suction device for the sweeper includes a suction cup housing 1 and a suction pipe 2. The suction pipe 2 is vertically installed on the suction cup housing 1. The top of the suction pipe 2 is connected to the suction negative pressure system of the sweeper through a pipe. A brush roller 3 is also installed at the bottom of the suction cup housing 1. The brush roller 3 is arranged along the width direction of the suction cup housing 1. A power component 4 that drives the brush roller 3 to rotate is also provided on the suction cup housing 1. The brush roller 3 is located behind the suction pipe 2. A front roller assembly 5 and a front water spray assembly 6 are provided at the front end of the suction cup housing 1. A rear roller assembly 7 and a rear water spray assembly 8 are provided at the rear end of the suction cup housing 1. Both the front water spray assembly 6 and the rear water spray assembly 8 are connected to the water supply system of the sweeper.

[0038] The brush roller 3 has bristles made of nylon or metal wire. There are two sets of power components 4, each mounted on opposite sides of the suction cup housing 1. The two sets of power components 4 work synchronously, driving the brush roller 3 to rotate. This synchronized operation of the two sets of power components 4 increases the rotation speed of the brush roller 3, resulting in better cleaning performance.

[0039] The power component 4 includes a hydraulic cycloidal motor 41 and a sprocket drive 42. The hydraulic cycloidal motor 41 is mounted on the top side of the suction cup housing 1. The sprocket drive 42 includes a first gear 421, a second gear 422, and a drive chain 423. The first gear 421 is connected to the end of the brush roller 3, and the second gear 422 is connected to the output shaft of the hydraulic cycloidal motor 41. The drive chain 423 is arranged vertically and sleeved between the first gear 421 and the second gear 422. The power component 4 designed above has a simple structure, is easy to install and maintain, and operates stably. The hydraulic cycloidal motor 41 has few teeth, a large working space volume, a compact structure, and a speed range of 10-500 rpm. It can directly drive the load without a reduction mechanism, thereby driving the brush roller 3 to rotate at high speed and stably, achieving a more thorough sweeping action on the road surface.

[0040] In this embodiment, the front water spray assembly 6 includes a first water pipe 61, a second water pipe 62, and multiple front nozzles 63. The first and second water pipes 61 and 62 are both obliquely installed at the front end of the suction cup housing 1, arranged in a figure-eight pattern. Multiple front nozzles 63 are spaced apart on the first and second water pipes 61 and 62, and are all used to spray water towards the road surface. The rear water spray assembly 8 includes a third water pipe 81 and rear nozzles 82. The third water pipe 81 is installed at the rear end of the suction cup housing 1, arranged parallel to the brush roller 3. Multiple rear nozzles 82 are spaced apart on the third water pipe 81 and are used to spray water towards the road surface. The aforementioned front water spray assembly 6 and rear water spray assembly 8 have a simple structure, are stable and easy to install, and can uniformly spray water to wash the road surface.

[0041] In this embodiment, the front roller assembly 5 has two sets. Extension plates 11 are respectively provided on both sides of the front end of the suction cup housing 1. The two sets of front roller assemblies 5 are respectively installed inside the extension plates 11. The height of the front roller assembly 5 is adjustable. The front roller assembly 5 includes a front bracket 51 and a first roller 52. The first roller 52 is rotatably mounted on the front bracket 51. Multiple vertically arranged strip grooves 111 are provided on the extension plates 11. The front bracket 51 is connected to the extension plates 11 by multiple sets of bolts 12, which pass through the strip grooves 111. The aforementioned front roller assembly 5 has a simple structure, is firmly installed, and its height can be finely adjusted as needed, providing good support and rolling guidance for the entire suction cup device.

[0042] In this embodiment, the rear roller assembly 7 has multiple sets, including a rear support 71 and a second roller 72. The rear support 71 is fixedly installed on the rear end face of the suction cup housing 1, and the second roller 72 is rotatably mounted on the rear support 71. The rear roller assembly 7 designed above has a simple structure, is firmly installed, is not easy to shake, and can provide good support and rolling guidance for the entire suction cup device.

[0043] In order to improve the structural strength of the suction cup housing 1 and the installation firmness of the second roller 72, the rear bracket 71 is also provided with a vertically arranged reinforcing rib 73, which is perpendicular to the upper surface of the suction cup housing 1.

[0044] The beneficial technical effects of the novel sweeping suction cup device for the sweeper truck according to the embodiments of this application are roughly as follows:

[0045] The front water spray assembly 6 can perform high-pressure water spraying to wash the road surface, and then the suction pipe 2 can suck up sewage and garbage from the road surface. The starting power assembly 4 can drive the brush roller 3 to sweep the road surface to loosen stubborn garbage. The rear water spray assembly 8 can also perform high-pressure water spraying to wash the road surface again. It has multiple functions and can combine the above four processes to achieve better road surface cleaning results for more stubborn garbage on the road surface. Moreover, the front water spray assembly 6 and / or the rear water spray assembly 8 can be selectively activated according to different road conditions, making the cleaning treatment more flexible and versatile.

[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
