[0020] Combination Figure 1-2This application describes a row alignment device for a divider, comprising a mounting base 1, an alignment base 2, an angle sensor 3, a first lever 4, a second lever 5, and a centering torsion spring 6. The alignment base 2 is rotatably connected to the mounting base 1. One end of the first lever 4 and the second lever 5 is connected to the alignment base 2, while the other end is suspended. The first lever 4 and the second lever 5 are set at an angle. The signal detection end of the angle sensor 3 is disposed between the alignment base 2 and the mounting base 1 to detect the relative angle between them. The signal output end of the angle sensor 3 is electrically connected to a controller. The centering torsion spring 6 is fixedly connected to the mounting base 1, and its two ends abut against the two sides of the alignment base 2. The two sides of the alignment base 2 are the mounting sides of the first lever 4 and the second lever 5.

[0021] In this embodiment, the mounting base 1 is fixedly connected to the divider, preferably, the mounting base 1 is fixed inside the cone of the divider.

[0022] In a specific embodiment of this application, the controller electrically connected to the angle sensor 3 can be a controller corresponding to the divider or a controller for agricultural machinery.

[0023] In a specific embodiment of this application, when the agricultural machinery moves between two rows of crops, the first lever 4 and the second lever 5 can contact the stalks of the crops through their rods. Under the limitation of the stalks, they drive the row base 2 to rotate relative to the mounting seat 1. During the rotation of the row base 2 relative to the mounting seat 1, the angle sensor 3 detects the relative rotation angle between the row base 2 and the mounting seat 1, thereby determining the position of the divider between the two rows of crops, so that the controller can adjust the movement direction of the divider. Specifically, the movement direction of the divider can be adjusted by directly adjusting the steering direction of the divider, or by adjusting the movement direction of the agricultural machinery.
