In the above technical solution of the suction nozzle device of the washing and sweeping vehicle, a more specific technical solution may also be: the scraper is provided with a plate body, a fixed clamping plate is arranged on the upper side of the plate body, and a plurality of hinged plates are arranged on the fixed clamping plate.
Due to the adoption of the technical scheme, compared with the prior art, the invention has the following beneficial effects:
1. a support frame is hinged with a scraper positioned in front of a suction nozzle, the upper part of the scraper is provided with a plurality of long holes vertical to the length direction, and a connecting rod penetrates through the long holes of the scraper; when the connecting rod is in a transverse position, the bottom of the connecting rod is in pressure joint with the lower side surface of the long hole of the scraper, and the scraper is in a position that the lower part of the scraper inclines backwards. When the piston rod extension of power cylinder drives the dwang clockwise rotation, the suction nozzle is by action of gravity downstream, drives the connecting rod clockwise rotation simultaneously, the bottom of connecting rod and the downside separation of scraper blade slot hole, and the scraper blade is erect under the action of gravity, strickles off rubbish and makes the even place in the place ahead of suction nozzle of rubbish, reinforcing suction nozzle absorbs the work effect of rubbish. The invention only needs one power cylinder to drive the suction nozzle to put down, and simultaneously enables the scraper to vertically enter the working position, thereby having simple structure and low manufacturing cost.
2. The scraper has the plate body, and the fixed splint is equipped with on the upside of plate body, is equipped with a plurality of articulated joints on the fixed splint, and the scraper installation of being convenient for is firm.

Detailed Description
The invention will be further described in detail with reference to the following examples:
as shown in fig. 1 and 2, the suction nozzle device of the washing and sweeping vehicle comprises a support frame 1, a power cylinder 3 is hinged on the upper portion of the support frame 1 through a rotating rod 2, one end of the rotating rod 2 is hinged with the support frame 1, the other end of the rotating rod is hinged with a piston rod of the power cylinder 3, a cylinder body of the power cylinder 3 is hinged with a tail fixing support lug 4, and the power cylinder 3 of the embodiment is an oil cylinder. Suction nozzles 6 are arranged on two sides of the lower portion of the support frame 1 through two connecting rods 8, the connecting rods 8 are respectively hinged with the suction nozzles 6 and the support frame 1, the suction nozzles 6 are connected with the rotating rod 2 through chain chains 5, and the chain chains 5 are connected to one end, close to the oil cylinder, of the rotating rod 2.
