Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of crop pollination, in particular to a high-efficiency pollination machine for crop hybrid seed production. BACKGROUND

[0002] Crop hybrid seed production is one of the core technologies of agricultural breeding. Through hybridization of different genotypes and selection of offspring, combined with modern biotechnology, hybrid advantage utilization and excellent variety breeding are realized. Hybrid seed production is a technology that forms pure or dominant varieties through hybridization of different genotypes (intraspecific or distant) parents combined with selection of offspring. The core lies in the separation and selection of traits generated by gene recombination, aiming to aggregate excellent genes of both parents or create super-parent types beyond parents. Hybrid advantage is manifested in significant improvement of growth rate, stress resistance, yield and other traits. For example, the popularization and application of hybrid rice and corn.

[0003] In the existing crop hybrid seed production technology, when fan air pollination is used, the device needs to be placed above the crop canopy for operation. The pollen diffusion process has defects. Specifically, the airflow field in an open space environment lacks effective barriers and is easily disturbed by natural wind, making it difficult to control the pollen diffusion trajectory. The horizontal drift distance exceeds the target area, and the vertical deposition uniformity is insufficient. This non-targeted diffusion phenomenon not only causes waste of valuable pollen resources, but also causes significant differences in pollen amount on plants. The pollination density of some individuals is lower than the critical value, leading to hybridization failure, ultimately reducing the hybridization rate of seed production, and seriously affecting the efficiency of large-scale seed production.

[0023] 1. The present invention uses an operating column, a push platform, a sliding column, a swing arm, a support column, a rotating block, a mounting platform, a rotating block, and a rotating column to coordinate with each other to maintain the pollination tube in an initial low position, facilitating operation from below the crop. This allows for continuous adjustment of the pollination tube's pitch angle to achieve precise elevation positioning, maintains alignment between the pollination tube axis and the crop inflorescence axis, and allows the ducted fan to generate negative pressure to extract pollen and spray it directionally through the pollination tube, achieving uniform atomization and spraying of pollen.

[0024] 2. The present invention can cover the entire width of a long strip of farmland through the coordinated use of a transmission column, a first gear, an engaging rack, a slider, a fixing frame, a mounting platform, and a pollination tube. This facilitates linear adjustment of the position of the pollination tube, and subsequently coordinates the pollination spray of the pollination tube so that in a flat farmland, a linear reciprocating motion can efficiently cover a long strip of land. This is particularly suitable for crops planted in rows, such as rice and wheat.

[0025] 3. The present invention uses the stabilizing column, the second gear, the third gear, the clamping plate, the clamping plate and the intermittent ring to make the mounting frame rotate periodically. Through the intermittent circular motion, the pollen is spread in a spiral shape, increasing the coverage area, avoiding the air flow turbulence caused by continuous rotation, and reducing the loss of pollen drift;

[0026] 4. The present invention realizes power diversion by driving the motor, stabilizing column, second gear, transmission column, first gear, rack, slider, fixing frame and pollination tube in coordination with each other, synchronously driving the linear displacement mechanism and intermittent rotation mechanism, achieving full coverage of the long strip plot by linear reciprocating motion, and circular pollen diffusion by intermittent rotation;

[0027] 5. The present invention uses an electric hydraulic rod as an actuator to provide stable linear thrust. The electric hydraulic rod, support frame, mounting frame, fixing frame and pollination tube work together to adjust the height of the pollination tube. It also works in conjunction with the linear reciprocating motion and intermittent rotation system to achieve three-dimensional pollination coverage, with high adaptability to reduce pollen drift loss.

[0028] 6. The present invention uses the pollination box as an independent container for loading pollen and sealing it for storage. Then, when the ducted fan is running, negative pressure is generated to suck the pollen in the pollination box into the pollination tube. The pollen in the pollination box can be pre-packaged and directly replaced during field operations. BRIEF DESCRIPTION OF THE DRAWINGS
