With the above structure, the same adjustment motor 6 can drive the adjustment mechanisms at all levels to adjust the deviation, pitch angle and deflection angle of the plow body 2 respectively, so that the structure of the opener is relatively compact. The above-mentioned deviation is the distance between the center of the plow body 2 and the center of the mounting base 1 .

When a certain variable needs to be adjusted, first determine which level of adjustment mechanism the variable needs to be adjusted corresponds to, and then control the clutch of the corresponding adjustment mechanism to be in a state where power can be transmitted, and control other clutches to disconnect, and finally control the motor to run, and then the required adjustment can be made. Variables are adjusted.

In the above structure, the structural design of the main transmission shaft 71 enables the power of the adjustment motor 6 to pass through the deformed connecting frame composed of the translation seat 31 and the two connecting rods 32, and transmit the power to the secondary adjustment mechanism 4 and the tertiary adjustment mechanism. Mechanism 5 realizes the design purpose that the same regulating motor 6 drives the operation of regulating mechanisms at all levels.

Difficulty transmitted to the connecting shaft 51 mounted at its end. When the deflection angle of the plow body 2 needs to be adjusted, the third clutch 74 is closed, and the other clutches are disconnected, and then the worm 59 is driven to rotate, so that the connecting shaft 51 can be rotated. After the adjustment is completed, the third clutch 74 is kept in the closed state. In this way, through the self-locking characteristic of the worm gear mechanism, the plow body 2 can be kept from changing the angle by itself.
