Description

Technical Field

[0001] The utility model relates to the technical field of rice harvesting, in particular to a rice male parent cutting and crushing machine. Background Art

[0002] In hybrid rice seed production, the male parent needs to be cut off and crushed after pollination to improve seed quality and purity. It can also create sufficient sunlight and nutrient conditions for the female parent's later growth and enhance the female parent's air permeability and light transmittance, thereby achieving the goal of increasing production and income.

[0003] Existing male parent removal equipment, such as the hybrid rice male parent harvesting mechanism and method disclosed in Patent Publication No. CN115211279A, and the self-propelled hybrid rice male parent cutting and returning machine disclosed in Patent Authorization No. CN218998896U, uses a cutting table with two or three vertically parallel axes, resulting in a complex structure and difficulty in miniaturization and lightweighting. Hybrid rice fields that have just been pollinated are typically deep muddy, and hybrid rice seed production generally uses a small row ratio planting model, with male parents planted in single or double rows and a distance of 50cm-80cm between adjacent female parents. If the equipment is too large, it will not be able to successfully complete the male parent harvesting and crushing operations in the field. Utility Model Content

[0004] The utility model aims 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 muddy paddy fields.

[0005] The technical solution of the present utility model is: a rice parent cutting and crushing machine, comprising 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 comprising a frame, a knife shaft upright and rotatably arranged in the frame, and a plurality of knife discs mounted on the knife shaft, one end of the frame is open, and a straw divider is hinged on the two side walls of the frame forming the opening, and the two straw dividers can adjust the opening and closing angles relative to the opening, and the driving mechanism is driven and connected to the knife shaft; a fixed blade is installed on at least one inner side wall of the frame, and a plurality of 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] The single-shaft design employed in the above scheme allows for lightweight and compact equipment, making it ideal for cutting and crushing rice straw in narrow single- or double-row paddy fields with deep, muddy soil. This design also allows for more space behind the blade, facilitating the smooth discharge of crushed rice straw, eliminating the need for a separate mower or deflector to assist with straw removal. This single-shaft design reduces the machine's width, and to prevent missed cuts, a straw divider is designed to guide rice straw into the cutter disc.

[0007] Preferably, the straw divider includes a guide plate, a first mounting plate is provided at the upper end of the side wall of the frame forming an opening, a second mounting plate is provided at the lower end of the side wall of the frame forming an opening, first mounting holes are respectively provided on the first mounting plate and the second mounting plate, and the two first mounting holes are coaxially arranged, a second mounting hole is also provided on the first mounting plate, and the second mounting hole is a waist-shaped hole, the upper end of the guide plate is hinged to the first mounting hole on the first mounting plate, and the lower end of the guide plate is hinged to the first mounting hole on the second mounting plate, and the guide plate is provided with a first locking member that can move in the second mounting hole and lock the open and closed position of the guide plate.

[0008] Preferably, the guide plate includes a flat plate, a first inclined plate and a second inclined plate connected in sequence, the flat plate is connected to the frame, and the second inclined plate forms a flared opening at the outer ends of the two crop dividers. The flared opening is similar to an outward-facing toe-shaped opening.

[0009] Preferably, the crop divider further comprises a guide rod, a plurality of which are provided in the height direction of the guide plate, one end of each guide rod being connected to the guide plate, and the other end of each guide rod extending into the frame, so that the guide rods on the two crop dividers form a constriction in the frame. The constriction is similar to an inward-facing toe.

[0010] The rice divider is specifically designed as a guide rod. During operation, the guide rod guides the rice parent into the cutter disc. The high-speed rotating cutter disc quickly pushes the rice parent to the fixed blade for cutting and crushing. The simplest guide rod structure is the easiest to implement, achieving lightweight and preventing missed cutting of the parent 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.

[0012] Preferably, the rice male parent cutting and crushing machine further comprises a rice presser hinged to the upper end of the frame, and the hinged rice presser can adjust the pitch angle toward the opening.

[0013] During operation, the father plant is pushed forward and bent by the straw press, so that the bent father plant can fall into the cutting table and be crushed by relying on its own gravity and the pulling force of the cutter disc. In this way, even if the height of the cutting table is lowered, the father plant can be effectively cut, and after the height of the cutting table is lowered, the weight of the machine itself is further reduced, making it easier to operate.

[0014] Preferably, the straw press includes a pressure rod and an adjustment plate connected to the end of the pressure rod, the frame forms an open side wall with a third mounting plate at the upper end, the third mounting plate is provided with a third mounting hole and a fourth mounting hole, the fourth mounting hole is a waist-shaped hole, one end of the adjustment plate is hinged to the third mounting hole, and the other end of the adjustment plate is provided with a second locking member that can move in the fourth mounting hole and lock the pitch position of the pressure rod.

[0015] Preferably, the cutter disc is provided with at least three cutting teeth, the width of the cutting teeth gradually decreases from the inside to the outside, and the cutting teeth are provided with inclined surfaces on both the positive and negative sides in the rotation direction to form cutting edges.

[0016] Preferably, the traveling mechanism includes a frame, traveling wheels rotatably arranged on the frame, and an armrest arranged on the frame. The cutting platform is mounted on the frame, and the armrest is located on a side of the cutting platform away from the opening.

[0017] Compared with the related art, the beneficial effects of the present invention are:

[0018] 1. The rice male parent cutting and crushing machine adopts a single blade shaft structure design, which makes the equipment lightweight and miniaturized, and is more suitable for cutting and crushing operations on narrow single or two rows of male parents in deep muddy paddy fields;
