Description

Air duct assembly and mower Technical Field The utility model relates to the technical field of mowers, in particular to an air duct assembly and a mowing machine. Background Mowers are commonly provided with two modes of grass cutting and grass collection to meet different work demands. In the grass cutting mode, the cut grass scraps are continuously crushed by a cutter and backfilled to a lawn, and in the grass collecting mode, the grass scraps are guided to a box body through a pipeline for concentrated collection. However, in the prior art, the switching of the two modes often depends on a complex structural design, for example, an adjustable baffle, a sliding rail or a movable air duct assembly is adopted to realize the mode switching, and meanwhile, an operating rod, a locking mechanism or a linkage mechanism is additionally arranged, so that the structure is complex and the manufacturing cost is high. In addition, the connection mode of the components is easy to wear at the joint due to frequent switching, so that the problems of grass scraps leakage or unstable box installation and the like occur, and the operation effect and efficiency are affected. Disclosure of utility model Aiming at the defects in the prior art, the utility model provides an air duct assembly and a mower, so as to solve the technical problem that the traditional air duct assembly in the related art is complex in structure. The utility model provides an air duct assembly, which is applied to a mower, wherein the mower comprises a grass discharging port, and the air duct assembly comprises: the air pipe is provided with an inlet end and an outlet end, and the inlet end of the air pipe is communicated with the grass discharging port; The mounting plate is wrapped on the outer side of the outlet end of the air pipe, and a first mounting point position and a second mounting point position are formed at different positions of the mounting plate respectively; The plug is detachably connected with the first installation point and is used for plugging the inlet end of the air pipe; The grass collecting box is detachably connected with the second installation point and is used for sealing the outlet end of the air pipe; The plug and the grass collecting box are selectively connected to the mounting plate to be configured into a grass breaking mode or a grass collecting mode. Further, the plug comprises a baffle and a handle which are connected, the baffle is used for blocking the inlet end of the air pipe, and one end of the handle, which is away from the baffle, extends out of the outlet end of the air pipe and is detachably connected with the first installation point. Further, the baffle is rotationally connected with the handle, a rotating shaft is arranged at the joint of the baffle and the handle, and a torsion spring is arranged on the rotating shaft sleeve. Further, the outer peripheral surface of the baffle is provided with a limiting protrusion, and the limiting protrusion can stay outside the grass discharging opening. Further, the first mounting point is provided with a plurality of hanging rings, and the handle is provided with a plurality of hooks for hanging the hanging rings. Further, the grass collecting box is of a semi-closed structure, and the mounting plate is arranged at the opening part of the grass collecting box and can cover the opening part of the grass collecting box. Further, one of the grass collecting box and the second installation point is provided with a plurality of buckles, the other is provided with a plurality of clamping holes, and the buckles are used for being buckled with the clamping holes. Further, the air duct comprises a first section and a second section, wherein the inlet end and the outlet end of the air duct are respectively formed at the distal ends of the first section and the second section, and the proximal ends of the first section and the second section are in floating connection. Further, the first section and the second section are respectively provided with a limit column and a limit notch which are matched with each other, and the limit column can float relative to the limit notch. The utility model also provides a mower comprising the air pipe assembly. Compared with the prior art, the utility model has the advantages that the first and second installation points are integrated through the single installation plate, the mode switching can be completed by using the alternative installation of the plug and the grass collection box, the number of parts is reduced, and the structure is optimized to reduce the manufacturing cost; the plug can seal the inlet end of the air pipe, the mounting plate and the outlet end of the air pipe are fixed in a wrapping manner, the grass collecting box is tightly connected with the mounting plate, the sealing performance of a grass scraps conveying path in the two modes is ensured, and the leakage risk is reduced.
