2. The transmission mechanism of an agricultural double-screw rotary cultivator according to claim 1, wherein: a plurality of buffer springs (12) are fixedly connected between the bottom surface of the horizontal end of the right-angle mounting frame (1) and the top surface of the mounting plate (2) through a connecting ring; vibration generated by the main spiral cutter shaft (6) and the auxiliary spiral cutter shaft (7) at the bottom of the mounting plate (2) is buffered through the buffer spring (12), so that the running stability of the device is improved.
3. The transmission mechanism of an agricultural double-screw rotary cultivator according to claim 1, wherein: an angle sensor (13) is fixedly arranged on the top surface of the mounting plate (2), and the angle sensor (13) is connected with a mobile power supply inside an external driving mechanism; the angle between the angle sensor (13) and the mounting plate (2) is detected in real time, so that the control is convenient.
4. The transmission mechanism of an agricultural double-screw rotary cultivator according to claim 1, wherein: a second hydraulic push rod (14) is fixedly arranged on the front side wall of the fixed seat (4) positioned at the front side through a bracket, a limiting rod (15) is fixedly connected to the lower end of the second hydraulic push rod (14), a plurality of limiting holes (16) are formed in the peripheral wall of the first rotating shaft (5) at equal round angles, and the limiting rod (15) is movably inserted into the limiting holes (16); after the angle adjustment of the mounting plate (2) is finished through the first hydraulic push rod (11), the second hydraulic push rod (14) drives the limiting rod (15) to be inserted into the limiting hole (16) to fix the angle of the mounting plate (2).
5. The transmission mechanism of an agricultural double-screw rotary cultivator according to claim 1, wherein: the circular groove (18) is formed in the inner wall around the kidney-shaped groove (8), the guide ring (19) is fixedly arranged on the outer side wall of the end part of the main spiral cutter shaft (6), and the guide ring (19) is slidably embedded in the circular groove (18); when the transmission adjusting mechanism (17) drives the auxiliary spiral cutter shaft (7) to move left and right in the kidney-shaped groove (8), the auxiliary spiral cutter shaft (7) is limited and guided to move left and right through the matched sliding of the guide ring (19) and the annular groove (18).
