Description

Cutter head structure and mower Technical Field The utility model relates to the technical field of mowers, in particular to a cutter head structure and a mowing machine. Background The traditional cutterhead mostly adopts a single-cavity design, and grass scraps are conveyed to a grass collecting container by utilizing air flow generated by a blade rotating at a high speed. However, when the cutter head is used for dealing with high grass amount or wet grass scraps, the grass scraps are often detained and accumulated due to the turbulence of air flow in the cavity, even blockage is caused, and the working efficiency is seriously affected. In order to improve the grass scraps processing capability, a double-cavity design for partition processing of the grass scraps is adopted, but in practical application, turbulence interference is still easy to generate in the vicinity of the grass discharge port due to the spatial proximity and air flow interaction of the two cavities, so that the double-cavity air flows counteract or offset each other, and the problem of blocking of the grass discharge port is aggravated. Disclosure of utility model Aiming at the defects in the prior art, the utility model provides a cutter disc structure and a mower, so as to solve the technical problem that the traditional cutter disc in the related art is easy to block. The utility model provides a cutterhead structure, which comprises: The cutter head main body is provided with a first inner cavity and a second inner cavity, and a grass discharging port is arranged between the first inner cavity and the second inner cavity; The wind-guiding assembly comprises two wind-guiding parts which are arranged independently of each other, the two wind-guiding parts are oppositely arranged at two ends of the grass discharging opening, each wind-guiding part is provided with a first wind-guiding surface and a second wind-guiding surface, and the first wind-guiding surface and the second wind-guiding surface are respectively arranged towards the first inner cavity and the second inner cavity so as to guide grass scraps in the first inner cavity and the second inner cavity to the grass discharging opening for discharging. Further, the cross sections of the first inner cavity and the second inner cavity are arranged in a circular shape. Further, the first inner cavity is tangential to the second inner cavity, and a tangential point formed by the first inner cavity and the second inner cavity is positioned in the grass discharging port. Further, the first air guiding surface is of an arc structure, and the center of the first air guiding surface coincides with the center of the first inner cavity, and/or The second air guide surface is of an arc-shaped structure, and the circle center of the second air guide surface coincides with the circle center of the second inner cavity. Further, one end of the first air guiding surface extends into the grass discharging opening, and the other end is connected with the inner wall of the first inner cavity, and/or One end of the second air guide surface extends into the grass discharging opening, and the other end of the second air guide surface is connected with the inner wall of the second inner cavity. Further, a chamfer structure is arranged at the joint of the first air guide surface and the first inner cavity and/or the joint of the second air guide surface and the second inner cavity. Further, the grass discharging port is provided with a grass discharging pipe. Further, one end of the grass discharging pipe is communicated with the grass discharging port, and the other end of the grass discharging pipe is arranged in an upward inclined mode. Further, the grass discharging pipe is of an integrated structure, or The grass discharging pipe comprises a first splicing part and a second splicing part, the first splicing part and the second splicing part are detachably connected, and a grass discharging channel is formed between the first splicing part and the second splicing part and is used for being communicated with the grass discharging port. The utility model also provides a mower, which comprises the cutter head structure. Compared with the prior art, the grass cutting machine has the advantages that the air flows in the first inner cavity and the second inner cavity can be guided in a directional mode through the first air guide surface and the second air guide surface of the air guide part, so that a synergistic effect is formed, instead of opposite flushing or offset, of the two air flows near the grass discharging port, the problem of grass cutting accumulation caused by air flow turbulence is reduced, and meanwhile, the two inner cavities are matched with the two air guide parts in a synergistic mode, and the grass cutting processing capacity and the grass discharging capacity are improved.
