Abstract
The utility model discloses a track boat-type tractor. A boat-shaped cover, a track type traveling gear, a hydraulic operation system, a transmission and an agricultural implement connection device are arranged on a machine frame, wherein the hydraulic operation system, the transmission and the agricultural implement connection device are designed anew. The track boat-type tractor has the advantages of a common track-type tractor and a boat-type tractor, a front driving track is used as a traveling system, grounding pressure is reduced, and compared with field passing ability of a commonly-used power chassis, the field passing ability of the track boat-type tractor is improved. In addition, the transmission with the synchronous rotation speed of traveling and output is designed anew, and therefore demands of crops with different row spaces in the process of seeding can be met. A hydraulic stepless speed change system is adopted as the operation control device, and therefore operation is convenient. By means of a hydraulic cylinder and parallelogram connection rods, the track boat-type tractor can be assembled with different agricultural implements and is suitable for power chassis of agricultural implements for paddy field leveling, seed rice seeding, rapeseed seeding, tobacco field ridging, paddy field stubble cleaning and weed burying and the like.
