Freier Zugriff

The invention belongs to the technical field of tractors and provides a novel paddy field tractor. The novel paddy field tractor comprises an engine and a transmission system which are connected through bolts. The engine and the transmission system are matched to form an assembly base body of the novel paddy field wheeled tractor. The novel paddy field tractor has the beneficial effects that firstly, through improvement on materials and optimization of the structure, a tractor body of the whole tractor is small in weight, cost is reduced, meanwhile, paddy field tires are arranged for operation, and the possibility that the tires sink into mud is reduced; secondly, a good waterproof mud-resisting effect on key components such as a drive train and electric appliance components is achieved, and the tractor is suitable for paddy field operation; thirdly, by the adoption of the structure that the installation centers of hubs of a front drive axle are lower than the center of the front driveaxle, the ground clearance is increased, and universality of paddy field operation is improved; fourthly, by the adoption of a compact engine structure, the length of the engine is reduced, and the axle base is effectively shortened; and meanwhile, the height of a hood is increased, and the sufficient steering angle of the front drive axle is guaranteed. The turning radius is reduced as small aspossible through the short axle base and the large steering angle, and the tractor can conveniently make a turn on the edge of a paddy field.

本发明属于拖拉机技术领域,包括发动机和传动系统,所述发动机和传动系统之间通过螺栓连接,所述发动机和传动系统配合构成新型水田轮式拖拉机的装配基体,本发明有益效果:、通过改善材料和优化结构,整机实现轻量化车身,降低成本,同时配以水田轮胎作业可减少陷入泥泞的可能;二、关键部件如传动系、电器部件等实现很好的防水防泥效果,适应水田作业;三、前驱动桥轮毂安装中心低于前驱动桥中心的结构,提高离地间隙,增加水田作业的通过性;四、紧凑的发动机结构,发动机长度减短,有效缩短轴距;同时机罩高度抬高,保证充足的前驱动桥转向角。短轴距大转向角实现尽量小的转弯半径,便于田间地头转弯。
