[0031] In order to make the purpose, technical scheme and advantages of the implementation of the utility model clearer, the utility model will now be further described in detail with reference to the accompanying drawings and the following examples so that the public can better understand the implementation method of the utility model. The specific implementation scheme of the utility model is as follows:

[0032] A negative pressure road deep sweeper comprises a chassis 2 provided with a walking mechanism 1, two columns 3 are provided on the chassis 2 in a fixed structure, a lifting frame 4 is provided on the column 3 in a sliding structure, a power mechanism for driving the lifting frame 4 to slide along the column 3 is also provided, and the power mechanism is connected to the chassis 2; a cab 5 is provided on the front side of the lifting frame 4 in a fixed structure, a cleaning mechanism 6 is provided below the cab 5, and two sets of parallel connecting rods 7 are provided between the cab 5 and the cleaning mechanism 6 in an articulated structure, and each set of connecting rods 7 has a plurality of connecting rods 7. There are two connecting rods 7, which are arranged in a parallelogram structure. A rope or chain is arranged between the cabs 5, one end of the rope or chain is connected to the cab 5, and the other end is connected to the cleaning mechanism 6; the cab is lifted by the lifting frame, and the cab drives the cleaning mechanism to lift by the rope or chain. The sweeping disc or bristles of the cleaning mechanism do not need to be replaced in a specific place, which simplifies the maintenance method and improves the maintenance efficiency; and when there is no need for cleaning work, the cleaning mechanism can be lifted by lifting the cab to reduce the load on the cleaning mechanism.

[0033] Specifically, the column 3 is arranged in a U-shaped structure, the openings of the two columns 3 are arranged opposite to each other, and the lifting frame 4 is arranged in an inverted U-shaped structure, including a connecting beam 41, and columns 42 are arranged on both sides of the connecting beam 41 with a fixed structure. The column 42 is connected to the U-shaped cavity of the column 3 in a sliding structure. The U-shaped structure of the column 3 is convenient for the installation of the column 42 and meets the need to connect the column 42 to the cab 5.

[0034] It should be noted that the power mechanism is a hydraulic cylinder, which is convenient for access to the hydraulic control system of the sanitation vehicle. Both ends of the hydraulic cylinder are connected to the connecting beam 41 and the chassis 2 in an articulated structure.

[0035] In this embodiment, the chain is a round-link chain. In other embodiments, it can also be a wire rope, which has a certain flexibility and avoids interfering with the cleaning mechanism during operation. The maintenance room can also lift the cleaning mechanism.

[0036] It should be elaborated that a bracket 9 for supporting the cab 5 is provided on the outer side wall of the column 42 in a fixed structure manner. The upper part of the cab 5 is connected to the upper part of the column 42 by bolts to ensure the stability of the connection structure between the cab 5 and the lifting frame 4.

[0037] Furthermore, a spring 10 is provided at the lower part of the bracket 9. The other end of the spring 10 is connected to the cleaning mechanism 6. By setting the spring 10, a lifting force is given to the cleaning mechanism to ensure that it can pass through rough roads and improve its passability.

[0038] A connecting plate 8 is provided at the upper parts of the two columns 3 by means of bolt connection to improve the stability of the columns 3.

[0039] The working principle and process of the present utility model are as follows:

[0040] During operation, the hydraulic cylinder places the cab 5 at an appropriate height through the lifting frame 4. At this time, the spring has a lifting force on the cleaning mechanism 6, and the rope or chain is not stressed.

[0041] When maintenance is required, the hydraulic cylinder is started. The hydraulic cylinder pushes the lifting frame 4 to rise. The lifting frame 4 drives the cab 5 to move upward. When the rope is tightened, it drives the cleaning mechanism 6 to leave the ground and stops at a predetermined position for the maintenance and replacement of the sweeping disc or brush of the cleaning mechanism 5.
