Description

Technical Field

[0001] The utility model relates to the technical field of sweeper vehicle components, in particular to an opening and closing mechanism of a front air inlet device of a dust suction port of a sweeper vehicle. Background Art

[0002] At present, there are many manufacturers of small sweepers, and there are various cleaning principles and mechanisms. The small sweepers with stronger adaptability to the ground are mainly those that work on the sweeping and suction principle. They sweep the garbage to the middle through the side brushes, and then use the vacuum suction formed in the trash can to suck the garbage into the trash can through the dust suction port and the dust suction pipe.

[0003] This makes the structure of the dust suction port directly related to the cleaning effect and cleaning efficiency. When cleaning mud and sand, the dust suction port is mostly designed to be relatively short, which will reduce the forward wind flow. At the same time, the front part of the dust suction port is mostly designed to be closed, leaving a small amount of air to enter. This can reduce energy consumption and save power in the cleaning of mud and sand. When cleaning large-volume garbage such as mineral water bottles and cans, the front part of the dust suction port needs to be designed to be open, otherwise it will directly affect the garbage entering the suction port and may even get stuck at the suction port. The front part of the dust suction port needs to be designed to be fully open, but this method has a higher overall energy consumption and the battery capacity will inevitably be insufficient. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the front part of the dust suction port in the prior art is closed, which makes it impossible to clean up large volumes of garbage, but the front part of the dust suction port is open, resulting in relatively high overall energy consumption, and an opening and closing mechanism of the front air inlet device of the dust suction port of a sweeper is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The opening and closing mechanism of the front air inlet device of the dust suction port of the sweeper comprises a pedal, the bottom of the pedal is fixedly connected with a connecting rod, the part of the connecting rod close to the bottom of the pedal is fixedly connected with the inner core in the brake line, the part of the connecting rod away from the pedal is movably clamped with the adjusting block, the middle part of the connecting rod is movably clamped with a limiting plate, the bottom of the limiting plate is movably connected with the adjusting block near the back, the inner side of the adjusting block is movably clamped with the brake line, the outer surface of the brake line is fixedly sleeved with a positioning plate at one end away from the brake line, the inner side of the brake line is movably sleeved with an inner core, the end of the inner core away from the adjusting block is threadedly connected with the connecting block, the end of the connecting block away from the positioning plate is movably sleeved with a connecting plate, the bottom of the connecting plate is movably sleeved with a first connecting frame, the front side of the first connecting frame is movably connected with a second connecting frame, and the front side of the second connecting frame is movably connected with a control panel.

In this way, large garbage can be cleaned continuously to improve work efficiency. The overall operation is relatively simple and convenient, which improves the convenience of operation during the cleaning process. The bottom plate and the top plate can be disassembled for daily cleaning and maintenance of the dust suction port. BRIEF DESCRIPTION OF THE DRAWINGS
