Description

Synchronous transmission structure of cutterhead and rear wheel and mower Technical Field The utility model relates to the technical field of mowers, in particular to a synchronous transmission structure of a cutter head and a rear wheel and a mowing machine. Background At present, the driving system of the mower has the following disadvantages: 1. The cutter of the cutter disc and the rear wheel adopt independent driving modes, so that a power transmission component of a driving system has multiple power branches, the complexity and the manufacturing cost of a mechanical component are increased, the space utilization rate is low due to split layout, and the overall structure compactness is poor; 2. For the double-cutter cooperative operation mode, the power transmission component of the driving system is integrated in the middle functional area of the cutter disc in a high density manner, and forms spatial interference with the grass discharging port. The layout forces the flow cross-section area of the grass discharging port to be compressed to a critical threshold, and when the instantaneous flux of forage increases suddenly or the work load changes suddenly, the grass discharging channel is easy to be blocked, so that the continuous operation stability and the mowing efficiency of the mower are affected. Disclosure of utility model Aiming at the defects in the prior art, the utility model provides a synchronous transmission structure of a cutter disc and a rear wheel and a mower, so as to solve the technical problems that the traditional transmission structure in the related art is poor in structural compactness and the size of a grass discharge opening is easily affected. The utility model provides a synchronous transmission structure of a cutterhead and a rear wheel, wherein the cutterhead and the rear wheel are arranged independently, the cutterhead is provided with two first installation areas and a second installation area positioned between the two first installation areas, and the synchronous transmission structure comprises: a main driving wheel coaxially provided with a first auxiliary driving wheel and a second auxiliary driving wheel; The first transmission assembly comprises two cutterhead pulleys, a first pulley, a second pulley and a tensioning wheel, wherein the two cutterhead pulleys are respectively and rotatably arranged in two first installation areas and are connected with the first driven driving wheel through a first belt, the first pulley is arranged in the second installation area and is positioned at the outer side of the first belt, and the second pulley and the tensioning wheel are arranged in any first installation area at intervals and are used for being connected with the first belt; The second transmission assembly is connected with the second driven wheel through a second belt and is used for driving the rear wheel to rotate; under the action of external force, the main driving wheel drives the first auxiliary driving wheel and the second auxiliary driving wheel to rotate simultaneously so as to link the cutterhead pulley and the rear wheel to move synchronously. Further, one cutterhead pulley of the cutterhead pulley arranged close to the tensioning wheel is located on the outer side of the first belt, and the other cutterhead pulley is located on the inner side of the first belt.
