Description

Technical Field

[0001] The utility model relates to the technical field of rice pollination, and specifically relates to a high-efficiency pollination device for hybrid rice. Background Art

[0002] In hybrid rice breeding, creating rich genetic variation through crosses between different parental lines is essential. Pollination is a key step in achieving hybridization. By transferring pollen from the male parent to the female parent's stigma, the genetic material of both parents is combined, potentially producing offspring with superior traits (such as high yield, pest and disease resistance, and lodging resistance). From a mechanical perspective, vibrations of appropriate frequency and intensity can cause the pollen within the anthers to overcome their own adhesion and the binding force of the anther walls, allowing them to scatter. Therefore, farmers often use rope vibrations to stimulate the anthers of the male parent rice, prompting a large amount of pollen to scatter.

[0003] The existing technology uses manual pulling ropes, and the vibration frequency and the tension of the ropes are difficult to control. The utility model solves the above problems. Utility Model Content

[0004] The utility model aims to solve the technical problem in the prior art of using manual rope pulling and the difficulty in controlling the vibration frequency and the tension of the rope, and further provides a hybrid rice efficient pollination device.

[0006] Preferably, the rope length adjustment structure includes a worm, which is rotatably connected to a bearing seat, which is connected to a connecting rod, the worm is meshingly connected to a worm wheel, the worm wheel shaft end is rotatably connected to the connecting rod, the worm wheel is concentrically connected to a rope roller, and the rope roller is connected to one end of the powder-raising rope.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] The synchronous movement of the tractors on both sides drives the stable horizontal displacement of the pull rope. The rope length adjustment structure adjusts the tension of the pull rope. The synchronous vibration of the connecting rods at both ends drives the pull rope to vibrate, which improves the pollen separation effect. The vibration frequency of the pull rope can be precisely adjusted without damaging the seedlings.

[0011] The height of the powder rope can be adjusted by controlling the height of the lifting plate to adapt to the height of rice varieties of different heights. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be described in detail below with reference to the accompanying drawings. Example

[0017] The following is combined with Figure 1 This embodiment describes an efficient hybrid rice pollination device, comprising: a bracket 1, the bracket 1 being connected to a traction vehicle, the bracket 1 being rotatably connected to two rotating shafts 2, the upper ends of the rotating shafts 2 being connected to a turntable 3, the turntable 3 being eccentrically connected to a shift lever 4, the two shift levers 4 being rotatably connected to the ends of a connecting rod 5, the middle portion of the connecting rod 5 being connected to a rope length adjustment structure 6, the rope roller of the rope length adjustment structure 6 being connected to a powder-raising rope 7, the other end of the powder-raising rope 7 being connected to the rope roller of another set of rope length adjustment structures 6, the two sets of rope length adjustment structures 6 being respectively located on both sides of the rice field and connected to the traction vehicle;

[0018] The traction vehicles on both sides are respectively located on both sides of the rice field. The pollen rope 7 is pulled out by controlling the rope length adjustment structure 6, so that the rope rollers of the two rope length adjustment structures 6 are connected through the pollen rope 7. After completion, the pollen rope 7 is locked. At this time, the height of the pollen rope 7 is the same as the height of the rice male flowers. The two traction vehicles are controlled to move forward synchronously, and the power of the rotating shaft 2 is turned on. The rotating shaft 2 drives the turntable 3 and the lever 4 to rotate. The two levers 4 cooperate with the eccentric rotation to drive the connecting rod 5 to vibrate back and forth. The connecting rod 5 drives the pollen rope 7 to vibrate through the rope length adjustment structure 6, so as to better control the amplitude and frequency of vibration, and ensure that the pollen falls without damaging the seedlings.

[0019] The rope length adjustment structure 6 includes a worm 61, which is rotatably connected to a bearing seat 62, which is connected to the connecting rod 5.

After the adjustment is completed, the rope length remains unchanged due to the self-locking action of the worm wheel.

[0021] The pollination device also includes a rope height adjustment mechanism 8, which includes a screw 81. The screw 81 is rotatably connected to the second bearing seat 82, the second bearing seat 82 is connected to the connecting rod 5, the screw 81 is threadedly connected to the adjusting plate 83, the adjusting plate 83 is connected to the lifting plate 84, the powder rope 7 passes through the adjustment hole of the lifting plate 84, and the powder rope 7 is slidably connected to the connecting rod 5;

[0022] When adjusting the height, the screw 81 is rotated, and the screw 81 drives the lifting plate 84 to slide in the connecting rod 5 through the adjusting plate 83. The lifting plate 84 drives the powder rope 7 to move through the adjusting hole to adjust the height of the powder rope 7.

[0023] The rotating shaft 2 is connected to a gear 9, and the two gears 9 of the same rotating shaft 2 are connected by a toothed belt 10;

[0024] The gear 9 and the toothed belt 10 ensure that the two shafts 2 rotate synchronously.
