Below in conjunction with the drawings and specific embodiments, detailed construction of the present invention is further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the present invention.
Fig. 2 is that in Fig. 1, embodiment is linked with the structural representation after mouldboard plow.
Fig. 3 is that in Fig. 1, example example is linked with the structural representation after rotovator.
The specific embodiment
As shown in Figure 1: a kind of preferred embodiment of a kind of articulated steering four wheel drive of the present invention farm tractor, comprises driving engine 7, the first change speed gear box 6, the first denticle case 5, the first transmission shaft 3, the second denticle case 2, the second change speed gear box 1, hydraulic oil pump (not shown in FIG.), hydraulic ram 8, axis of traction (not indicating in figure), spindle arm 11, vehicle frame (not indicating in figure), bearing box 12, second driving shaft 4; The first change speed gear box 6 comprises power intake, main mouth, inferior mouth, and the power intake of the first change speed gear box 6 is connected with driving engine 7, and the main mouth of the first change speed gear box 6 is connected with the input end of the first denticle case 5; The front end of the first transmission shaft 3 is connected with the mouth of the first denticle case 5, and the rear end of the first transmission shaft 3 is connected with the mouth of the second denticle case 2; The second change speed gear box 1 and the first change speed gear box 6 are same gear box of tractor, and the main mouth of the second change speed gear box 1 is connected with the input end of the second denticle case 2.The front end of second driving shaft 4 is connected with the inferior mouth of the first change speed gear box 6, and the rear end of second driving shaft 4 is connected with bearing box 12.Vehicle frame (not indicating in figure) is connected with axis of traction (not indicating in figure); Spindle arm 11 is welded on axis of traction (not indicating in figure) top, spindle arm 11 comprises adapter shaft 9, adapter shaft 9 is connected with the front portion of spindle arm 11 by turning cylinder 10, adapter shaft 9 can rotate moving axis 10 shaft centre line rotate, the oil cylinder body of hydraulic ram 8 is connected with vehicle frame (not indicating in figure), the piston rod of hydraulic ram 8 is connected with adapter shaft 9, and hydraulic oil pump (not shown in FIG.) is arranged on driving engine 7.
