6. The double-shaft rotary cultivator of claim 1, wherein the working method of the double-shaft rotary cultivator comprises the following specific steps:
the method comprises the following steps: the whole rotary cultivator is fixedly connected with a tractor through a portal frame (5), a main gearbox (6) is connected with the tractor through a universal joint, the rotary power of the tractor is transmitted to a bevel gear shaft (20) through the universal joint in the starting process of the tractor, the rotary power is changed in the rotating direction and transmitted downwards through the meshing of the bevel gear shaft (20) and bevel gears, one part of the power is transmitted to a three-shaft reduction gear and a four-shaft gear, then a main shaft (2) is driven to rotate through a direct-drive transmission chain (8), a rotary blade (3) is driven to rotate by the rotation of the main shaft (2) to complete the first rotary tillage, the other part of the power is transmitted to a side transmission assembly (11) through a transmission shaft (9), so that a large shaft (16) inside the side transmission assembly (11) is driven to rotate, and the large shaft (16) drives a small shaft (19) to rotate by a lower spline shaft (18) in the rotating process, the small shaft (19) drives the auxiliary shaft (15) to rotate in the rotating process so as to drive the stubble-cleaning cutter (14) to rotate, the whole rotary cultivator advances along with the advancing of the tractor, the small plough body (4) is used for shoveling soil in the advancing process, the rotary tillage cutter (3) is driven to carry out rotary tillage by the rotation of the main shaft (2), the auxiliary shaft (15) is always rotated in the rotating process of the main shaft (2), and the auxiliary shaft (15) is used for driving the stubble-cleaning cutter (14) to rotate so as to thoroughly cut and crush the straws which are not completely stubble-cleaned;
step two: if the straws to be rotary-tilled are drier straws in the rotary tillage process, the gears of the side gearbox (12) are switched, the gear of the side gearbox (12) is lifted by using the gear shifting rod (21), so that the speed of the large shaft (16) is increased, the rotating speed of the small shaft (19) is increased by the lower spline shaft (18) of the large shaft (16) in the speed increasing process, so that the rotating speed of the auxiliary shaft (15) is increased, if the straws to be rotary-tilled are fresh straws with moisture, the gear of the side gearbox (12) can be reduced by using the gear shifting rod (21), so that the large shaft (16) is decelerated, the rotating speed of the small shaft (19) is reduced by the lower spline shaft (18) of the large shaft (16) in the deceleration process, so that the rotating speed of the auxiliary shaft (15) is reduced, and the auxiliary shaft (15) runs at a low speed.
