Description

Technical Field

[0001] This utility model relates to the technical field of fruit tree pollination devices, and more specifically, to an artificial pollination device for fruit trees. Background Technology

[0002] Laiyang pear and Qiuyue pear are both renowned pear varieties in my country. Modern agricultural research continuously optimizes these traditional famous pear varieties. Pollination is a crucial step in this optimization process, affecting both fruit yield and quality. Currently, artificial pollination devices for pear trees are mainly divided into three types: spray type, roller brush type, and spot pollination type. However, these devices have significant technical shortcomings in practical application, making it difficult to balance pollination effectiveness, flower protection, and operational efficiency. 1. Spray-type device: Relies on high-pressure airflow to transport pollen, the pollen dispersion rate is as high as 40%-60%, which not only causes a lot of pollen waste, but is also easily affected by external wind, resulting in uneven pollination. Some flowers cannot effectively contact the pollen, affecting the pollination success rate. 2. Roller brush type device: The rigid bristles come into direct contact with the flowers. During the rolling pollination process, the pear flower stigma or petals are easily scratched. Especially for the delicate flowers that have just opened, the damage rate can reach more than 20%, which directly affects the subsequent fruit setting rate. 3. Point-to-point pollination device: It requires manual hand-held device to touch each flower to complete the pollination. The average daily working area of ​​a single person is less than 0.5 acres, and the work efficiency is extremely low. Moreover, the operator needs to raise his hands and bend over for a long time, which is labor-intensive and significantly increases labor costs, making it difficult to meet the pollination needs of large-scale orchards.

[0003] To address the aforementioned shortcomings, there is an urgent need for an artificial pollination device that can achieve precise pollination, minimal flower damage, and high efficiency, in order to overcome the deficiencies of existing technologies. Utility Model Content

Inside, a fan 10 and a flow equalization mesh plate 11 are installed in sequence along the airflow direction. The fan 10 is a miniature axial flow fan 10, which is used to generate a stable airflow to disperse pollen. The flow equalization mesh plate 11 is a porous metal mesh with a pore size of 1-2mm. It is located near the bottom inside the fixed shell 8, which can make the airflow blown by the fan 10 diffuse evenly and avoid pollen aggregation or dispersion caused by excessive local airflow.

[0028] The pollination cover 1 is a funnel-shaped transparent plastic structure with a small diameter end of 5-8cm and a large diameter end of 15-20cm. The small diameter end is fixedly connected to the lower end of the fixing shell 8 by threads or buckles, while the large diameter end faces down to limit the pollen diffusion range and reduce external interference. The flower cover 2 is a flexible structure made of polyester fiber, which has elastic deformation properties. Its upper end is fixedly connected to the large diameter end of the pollination cover 1, and its lower end is an open opening, which is used to wrap the flower clusters to be pollinated to prevent pollen from drifting out of the flower clusters. At the same time, the flexible material can avoid damaging the flowers.

[0033] The powder spraying assembly 4 is used to stably deliver pollen into the pollination cover 1, and includes a nozzle 41, a powder spraying pipe 42, a sealing cover 44, a pollen storage tank 45, an air inlet pipe 46, and a micro air pump 47. The pollen storage container 45 is a transparent plastic container with a capacity of 50-100mL. It is detachably connected to the lower side of the sealing cap 44 via threads, making it easy to replenish pollen.

[0034] The sealing cap 44 is made of plastic and is installed in the middle of the support rod 5 through the sleeve 43. It has an airflow channel inside for connecting the powder spraying pipe 42 and the air inlet pipe 46.

[0035] The miniature air pump 47 is a low-pressure, silent air pump, fixed on the support rod 5 near the fixed housing 8, used to generate an airflow to propel pollen.

[0039] In addition, a charging power supply 6 and a switch button 9 are provided. The charging power supply 6 is a rechargeable lithium battery, which is fixed to the support rod 5 near the handle 7 by a buckle, and is used to power the fan 10 and the mini air pump 47. The switch button 9 is a two-stage dual-speed button, which controls the fan 10 and the mini air pump 47 respectively. In the first speed mode, the fan 10 runs, and in the second speed mode, the mini air pump 47 and the fan 10 run simultaneously.

The operator holds handle 7 and aligns the flower cover 2 with the flower cluster to be pollinated; pulls handle 313 downwards, the pull plate 312 slides down along the guide rod 314, pulls the main pull rope 32, the auxiliary pull rope 34 tightens and pulls the elastic rope loop 33 to contract, the lower opening of the flower cover 2 increases, and the flower cover 2 is placed on the flower cluster to be pollinated until it completely covers the flower cluster; releases handle 313, the return spring 315 pushes the pull plate 312 to return to its original position, the elastic rope loop 33 rebounds, ensuring that the flower cover 2 fits the flower cluster without squeezing the flowers; Press the switch button 9 to set it to the second position, start the fan 10 and the micro air pump 47, and then quickly set the switch button 9 to the first position. The micro air pump 47 quickly generates an airflow, which enters the sealing cover 44 through the air inlet pipe 46 and pushes the pollen in the pollen storage tank 45 to the spray nozzle 41 along the spray pipe 42. The spray nozzle 41 atomizes the pollen and sprays it into the pollination cover 1. The airflow generated by the fan 10 is evenly diffused by the flow equalization mesh plate 11 and blows the pollen in the pollination cover 1 evenly onto the flower clusters to complete the pollination. After pollination is complete, turn off switch button 9; pull down handle 313 again to expand the opening of the flower cover 2 and remove it from the current flower cluster; move the device to the next group of flower clusters and repeat the above operation steps until all pear trees are pollinated.
