The cutter shaft of the cutting table adopts a vertical parallel double or three-axis, the structure is complex, and the equipment is difficult to miniaturize and lighten. Hybrid rice fields that have just been pollinated are basically deep mud fields, and the hybrid rice seed production model generally adopts a small row ratio planting model. The male parent is planted in a single row or double row, and the distance between two adjacent female parents is between 50cm-80cm. If the equipment is too large, it will not be able to go into the field smoothly to complete the harvesting and crushing of the male parent. Summary of the invention

[0004] The object of the present invention is to provide a rice male parent cutting and crushing machine, which is more suitable for cutting and crushing operations of narrow single-row or two-row male parents in deep mud paddy fields.

[0005] The technical solution of the present invention is: a rice male parent cutting and crushing machine, including a walking mechanism, a cutting platform mounted on the walking mechanism, and a driving mechanism for controlling the movement of the cutting platform, the cutting platform includes a frame, a knife shaft upright and rotatably arranged in the frame, and a plurality of knife discs installed on the knife shaft, one end of the frame is open, and the two side walls of the frame forming the opening are hinged with a straw divider, the two straw dividers can adjust the opening and closing angles relative to the opening, and the driving mechanism is connected to the knife shaft driving; a fixed blade is installed on at least one inner side wall of the frame, and a plurality of the fixed blades are arranged in the height direction of the frame, the fixed blades are arranged close to the opening, and the fixed blades are arranged near the knife disc.

[0006] In the above scheme, the structural design of a single blade shaft is adopted, so that the equipment can be lightweight and miniaturized, which is more suitable for cutting and crushing narrow single-row or two-row parent plants in deep mud paddy fields. The structural design of a single blade shaft makes the space behind the blade shaft relatively large, which is more conducive to the smooth discharge of crushed rice straw, and no additional mower or guide plate is required to assist in the discharge of straw. The structure of a single blade shaft is adopted, and the width of the machine is reduced. In order to avoid missing when cutting the parent plants, a straw divider is designed to guide the rice parent plants into the blade disc through the straw divider.

The constriction refers to a shape similar to an inner toe.

[0010] The rice divider is specifically designed as a guide rod. When working, the rice parent is guided into the knife disc by the guide rod, and the high-speed rotating knife disc quickly pushes the rice parent to the fixed blade for cutting and crushing. The simplest guide rod structure is adopted in the easiest way to achieve lightweight and avoid missing cutting of the parent.

[0011] Preferably, the cutter disc has a radius R, and a vertical distance L is formed between the end of the guide rod and the center of the cutter shaft, where L<R. The parent is introduced into the working range of the cutter disc through the guide rod.
