Abstract
Description
Technical Field
[0001] This utility model relates to the field of fruit tree pollinators, and in particular to a pollen shaker for fruit tree pollination. Background Technology
[0002] The pollen shaker works by mechanically vibrating to dislodge pollen from male flowers and then using wind or other equipment to transfer it to the stigma of female flowers, thus completing the pollination process. It typically consists of a vibrating device and a fan. The vibrations from the vibrating device loosen the pollen from the male flowers and allow it to be dispersed by the wind to nearby female flowers, mimicking natural pollination. The pollen shaker is particularly suitable for large-scale orchards or environments where natural pollination conditions are not ideal, effectively improving the pollination rate and ensuring fruit quality and yield. In this way, the pollination process of fruit trees becomes more efficient and controllable, especially when pollen is insufficient or environmental conditions are unfavorable, effectively compensating for the deficiencies of natural pollination.
[0003] The pollen shaker works by artificially simulating the natural pollination process, transferring pollen from male flowers to female flowers to pollinate fruit trees. This device typically uses vibration, airflow, or mechanical transfer to shake or disperse pollen from male flowers, then delivers the pollen to the stigma of the female flower, completing the pollination. The pollinator can adjust the vibration intensity or wind speed to suit the pollination needs of different fruit tree varieties. Even in the absence of sufficient pollinating insects or under unfavorable environmental conditions, the pollinator can provide stable pollination results, ensuring normal fruit development and increasing yield. Through this artificial intervention, fruit tree pollination becomes more efficient and controllable, especially in large-scale planting and under harsh climatic conditions, significantly improving the quality and quantity of fruit production.
[0004] In existing technologies, most pollen shakers for fruit tree pollination employ a single pollination method, typically relying on vibration or airflow to transfer pollen. However, this single method cannot adequately meet the pollination needs of different fruit trees. For example, some fruit trees are better suited to vibration-based pollination, while others rely more on airflow for pollen dispersal. When environmental conditions or the needs of fruit tree varieties change, shakers with a single pollination method struggle to provide flexibility, leading to low pollination efficiency or poor fruit development. Therefore, this paper proposes a pollen shaker for fruit tree pollination to address these issues. Utility Model Content

[0016] 1. In this utility model, when fruit trees cannot be pollinated by the suction method, the vibration motor fixed to the outside of the lifting push rod by the motor mounting block and the mounting support ring is started, which drives the polarization block fixed to the drive end of the vibration motor to rotate, thereby driving the sliding squeezing block to slide inside the guide protection block. Finally, the sliding squeezing block pushes the impact block to reciprocate, thereby knocking the lifting push rod and generating vibration on the pollination head, causing the pollen in the flower in contact with the pollination head to fall off.

The multiple pipe clamps located at the driving end of the lifting push rod act as further guiding components to drive the pollination tube to rise, so that the pollination head will not be affected by the lifting and lowering of the lifting push rod.

[0026] Reference Figures 3 to 5 This utility model provides an embodiment of a pollen shaker for fruit tree pollination, comprising a fixed frame 1. The fixed frame 1 serves as the supporting structure for the entire pollen shaker, providing a stable foundation to ensure the pollination mechanism and vibration mechanism can be securely installed, guaranteeing safe operation of the equipment. An air bladder 2 is fixedly connected inside the fixed frame 1. The air bladder 2 is used to adjust the force of pollen shaking through air pressure.

A filter shaft 13 is fixedly connected inside the air duct 7.

[0030] Reference Figure 1 , Figure 2 , Figure 4 The pollination mechanism includes an air duct 7, which serves as a transmission channel for airflow, delivering air to the airbag 2 and helping to control the operation of the pollination head 11. The air duct 7 connects the pollen collection tank 8 and the pollination head 11. By adjusting the airflow, the uniform distribution of pollen is ensured. The air duct 7 is externally fixedly connected to the inside of the fixing frame 1. The other end of the air duct 7 is externally fixedly connected to the pollen collection tank 8, which is used to collect and store pollen. The pollen duct 8 is internally fixedly connected to the pollen duct 9, which is responsible for transporting pollen from the pollen collection tank 8 to the pollination head 11. The other end of the pollen duct 9 is internally fixedly connected to the pollination head 11. The top of the driving end of the lifting push rod 5 is fixedly connected to the guide clamp 10, which is used to guide the pollen duct 9 to the correct position, ensuring that the pollen can be accurately transferred from the pollen duct 9 to the pollination head 11. The outside of the pollen duct 9 is fixedly connected to the inside of the guide clamp 10. The outside of the lifting push rod 5 is slidably connected to multiple pipe clamps 6, and the outside of the air duct 7 is slidably connected to the inside of multiple pipe clamps 6. The top of the pollination head 11 is a semi-circular block, and the inside of the pollination head 11 has multiple through holes.
[0031] Working principle: During pollination, the air bladder 2 is pressed and then suddenly released, causing a sudden change in the air pressure inside the air bladder 2, thereby generating suction. The suction is guided by the air guide tube 7 and the pollen guide tube 9 to the pollination head 11. The pollen from the flower's stamen is then drawn into the pollination head 11 and guided into the pollen collection tank 8 by the pollen guide tube 9. The filter shaft 13 located inside the air guide tube 7 prevents pollen from entering the air bladder 2, thus making it difficult to remove the pollen, causing pollen waste and putting a burden on the air bladder 2.
[0032] When the flower is too high, the lifting push rod 5, which is fixed to the top of the fixed frame 1 by the push rod base 4, is activated. The guide clamp 10 at the drive end of the lifting push rod 5 restricts the pollen guide tube 9, so that the pollen guide tube 9 moves with the movement of the lifting push rod 5, thereby allowing the pollination head 11 to contact the flower at a high position. The multiple pipe clamps 6 sliding on the drive end of the lifting push rod 5 restrict the pollen guide tube 9 to prevent the pollen guide tube 9 from affecting the pollination head 11 due to the sliding of the lifting push rod 5.
[0033] When the suction method fails to pollinate, the mounting support ring 12, which is fixedly connected to the drive end of the lifting push rod 5, serves as the mounting bracket for the motor mounting block 14. The motor mounting bracket 16, in cooperation with the motor mounting block 14, fixes the vibration motor 15 to the drive end of the lifting push rod 5. Then, the vibration motor 15 starts, driving the polarization block 18, which is fixed to the drive end of the vibration motor 15, to rotate. The polarization block 18 drives the push block, which is fixed outside the polarization block 18, to push the sliding extrusion block 19 to slide. The sliding extrusion block 19 applies pressure to the impact block 21, causing the impact block 21 to vibrate the lifting push rod 5. This causes the pollination head 11 to vibrate, and the pollination head 11 removes pollen from the flower. The pollination head 11 then absorbs the pollen, thus achieving the purpose of pollination. At the same time, when the polarization block 18 retracts, the buffer spring 24, which is fixed to the rear side of the impact block 21 by the spring mounting seat 23, absorbs the impact force and prevents the impact from damaging the device.
