Description

Cutter head lifting mechanism and mower Technical Field The utility model relates to the technical field of mowers, in particular to a lifting mechanism of a cutter head and a mower. Background The cutter head of the mower is a core component for cutting forage, and the stability and the synchronism of a lifting mechanism of the mower directly influence the cutting effect, the lawn flatness and the service life of equipment. The traditional mower cutterhead is usually lifted and adjusted by adopting a single-point driving design, however, single-point force application easily causes the cutterhead to incline in the lifting process, and particularly when aiming at a wide cutterhead or a working scene with large topographic relief, heights of two sides (or two ends) of the cutterhead are difficult to synchronize, so that uneven height of grass stubble and local overload abrasion of blades are caused, and even deformation of the cutterhead or damage of a driving mechanism is caused due to uneven stress. Disclosure of utility model Aiming at the defects in the prior art, the utility model provides a lifting mechanism of a cutterhead and a mower, and aims to solve the technical problems that single-point stress of a traditional cutterhead is easy to generate stress and uneven in height in the related art. The utility model provides a lifting mechanism of a cutter head, wherein a first installation position and a second installation position are arranged on the cutter head at intervals, and the lifting mechanism comprises: the frame body is suspended above the cutterhead; The driving assembly is movably arranged on the frame body, and is provided with a first driving position and a second driving position on the movable stroke, and the driving assembly is used for respectively driving the cutterhead to descend or ascend when the driving assembly is arranged at the first driving position and the second driving position; The rotary assembly comprises a first rotary structure, a second rotary structure and a rotary connecting rod, wherein the first rotary structure and the second rotary structure are respectively arranged at the first installation position and the second installation position and are connected through the rotary connecting rod; The driving assembly is in driving connection with the first rotating structure, so that the second rotating structure is linked through the first rotating structure on the moving stroke of the driving assembly, and the first installation position and the second installation position of the cutterhead are synchronously lifted.
