Description

Technical Field

[0001] This utility model relates to the field of plant breeding technology, and in particular to an artificial pollination device for dates. Background Technology

[0002] Artificial pollination refers to the technique of transferring plant pollen to the stigma by artificial means to improve the seed yield or to improve plant species in a targeted manner. It is a necessary means of purposefully selecting parent plants. In fruit tree production, artificial pollination is often required for fruit trees that are self-infertile and cross-pollinated, especially when there is a lack of pollinating trees or when the weather is bad during the flowering period and affects normal natural pollination.

[0003] Date palms belong to the palm family and are tall plants, with their inflorescences typically located at the top of the crown. In major date-producing areas, artificial pollination is used to ensure date yield. Currently, artificial pollination of dates involves picking fully opened male inflorescences and sprinkling the pollen from the male inflorescences onto the open female flowers, or placing the male inflorescences above the female flowers, allowing the pollen from the male flowers to naturally drift to the female flowers via wind, thus achieving successful pollination.

[0004] However, date palm trees can grow to heights of over 30 meters, making the top of the canopy a particularly windy area. During pollination, pollen is easily dispersed by strong winds, resulting in significant pollen drift and loss, and preventing it from accurately and effectively attaching to the target female inflorescence. This not only wastes valuable pollen resources but also directly leads to low pollination success rates and unstable fruit set, ultimately affecting the yield and quality of dates. Utility Model Content

[0005] Therefore, it is necessary to provide an artificial pollination device for dates to address the aforementioned technical problems.

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0024] like Figures 1-3 As shown, an artificial pollination device for dates is provided, which includes: a powder spraying frame 100, a support rod 120, a pollen bottle 130, an air blowing assembly 160, a connecting rod 1211, and a folded membrane 1212.

[0025] The first end of the support rod 120 is disposed on the powder spraying frame 100. A pollen delivery hose 140 is disposed on the support rod 120. The first end of the pollen delivery hose 140 is connected to the air outlet of the pollen bottle 130. The second end of the pollen delivery hose 140 is disposed on the second end of the support rod 120. An air chamber 121 is disposed along the length of the second end of the support rod 120. An air supply pipe 150 is also disposed on the support rod 120. The air inlet of the air supply pipe 150 is connected to the air blowing assembly 160. The outlet end of the 0 is connected to the first end of the air chamber 121. There are multiple connecting rods 1211, which are equidistantly distributed around the center of the air chamber 121. The first end of the connecting rod 1211 is slidably disposed in the air chamber 121. The second end of the support rod 120 is provided with a conical inclined surface 122. The air supply pipe 150 delivers high-pressure gas into the air chamber 121, which pushes the connecting rod 1211 to slide along the conical inclined surface 122 and unfold in a conical shape. The folded membrane 1212 is disposed between adjacent connecting rods 1211.

[0026] In this embodiment, the powder spraying frame 100 is gun-shaped for easy gripping. A pollen delivery hose 140 and an air delivery pipe 150 are mounted on the powder spraying frame 100, both extending along the length of the support rod 120. The pollen delivery hose 140 and the air delivery pipe 150 can be connected to the support rod 120 via straps. The pollen bottle 130 is connected to the second end of the support rod 120 via the pollen delivery hose 140. The air blowing assembly 160 is connected to the second end of the support rod 120 via the air delivery pipe 150. An air blowing pipe 110 is also connected to the outlet end of the air blowing assembly, and the air blowing pipe 110 is connected to the middle of the pollen delivery hose 140.

[0027] First, pollen is loaded into pollen bottle 130. Then, the air-blowing assembly 160 is activated, and airflow enters the pollen delivery hose 140 through the air-blowing pipe 110, increasing the flow velocity within the hose and carrying the pollen out of pollen bottle 130. A mixture of pollen and gas is formed within the hose 140. This mixture is then transported through the hose 140 to the pollen outlet at the top of support rod 120. Simultaneously, another portion of high-pressure gas generated by the air-blowing assembly 160 enters the air chamber 121 at the top of support rod 120 through the air delivery pipe 150. The air pressure in the air delivery pipe 150 is higher than the air pressure in the pollen delivery hose 140. The air-blowing assembly 160 includes, but is not limited to, an air pump. The high-pressure gas pushes the connecting rod 1211, which is made of an elastic material, to slide outward within the air chamber 121. Because the support rod 120 has a tapered inclined surface 122 at its top, the connecting rod 1211 slides along the tapered inclined surface 122 and unfolds outward to form a tapered structure. The folded membrane 1212 unfolds along with the connecting rod 1211, forming a temporary windproof cover that surrounds the female inflorescence. This unfolded windproof cover structure is more adaptable to high-altitude working environments. The mixture of pollen and gas is sprayed from the pollen outlet at the top of the support rod 120 and, under the protection of the windproof cover, precisely adheres to the female inflorescence, achieving precise pollen spraying and effectively preventing pollen from being scattered and lost by the wind.

[0028] like Figure 2 and Figure 3 As shown, in one embodiment, the folded membrane 1212 is fan-shaped, and the arc edge of the folded membrane 1212 is disposed at the second end of the connecting rod 1211.

[0029] In this embodiment, the shape of the folded membrane 1212 matches the unfolding trajectory of the connecting rod 1211, forming a continuous conical protective surface after unfolding. This improves the sealing and protective effect of the windproof cover, further reducing pollen loss.

[0030] like Figure 2 and Figure 3As shown, in one embodiment, a sealing ring 1213 is provided at the end of the connecting rod 1211, and the sealing ring 1213 is in sealing contact with the inner wall of the air chamber 121.

[0031] In this embodiment, the sealing ring 1213 seals against the inner wall of the air chamber 121 to ensure that the gas inside the air chamber 121 does not leak. The gas supply pipe 150 delivers high-pressure gas into the air chamber 121 until the gas pressure is sufficient to push the sealing ring 1213 to slide along the inside of the air chamber 121. At this point, the sealing ring 1213 pushes the connecting rod 1211 to unfold. This improves the sealing performance and reliability of the pneumatic system, ensuring the stability of the unfolding action. Furthermore, the sealing ring 1213 simultaneously pushes multiple connecting rods 1211 to extend from the air chamber 121, ensuring that the windproof shield can be fully unfolded.

[0032] like Figure 2 and Figure 3 As shown, in one embodiment, a return spring 1214 is provided inside the air cavity 121 along the length direction. The first end of the return spring 1214 is connected to the first end of the air cavity 121, and the second end of the return spring 1214 is connected to the sealing ring 1213. The return spring 1214 is in a stretched state.

[0033] In this embodiment, when the gas supply pipe 150 delivers high-pressure gas into the gas chamber 121, the sealing ring 1213 slides along the length of the gas chamber 121, and the return spring 1214 is in a stretched state. When the gas pressure in the gas chamber 121 decreases, the return spring 1214 contracts, pulling the sealing ring 1213 toward the inside of the gas chamber 121, and simultaneously pulling the connecting rod 1211 back into the gas chamber 121, realizing the rapid retraction and folding of the windproof cover, which is convenient for carrying and reuse.

[0034] like Figures 2-5 As shown, in one embodiment, the first end of the air chamber 121 is provided with an air vent 1215, and an air-sealing cover 1216 is rotatably provided inside the air chamber 121, the air-sealing cover 1216 being used to fasten to the air vent 1215.

[0035] In this embodiment, the air-sealing cover 1216 is positioned between the air inlet and the vent 1215 of the air chamber 121 during rotation. In its natural state, the air-sealing cover 1216 is biased towards the air inlet side of the air chamber 121. When the air supply pipe 150 delivers high-pressure gas into the air chamber 121, the high-pressure gas impacts the air-sealing cover 1216, causing it to deflect towards the vent 1215 via the rotation shaft until it is engaged with the vent 1215. When it is necessary to retract the connecting rods 1211, the air blowing assembly 160 stops supplying air, opens the vent 1215 of the air-sealing cover 1216, and the gas in the air chamber 121 is quickly discharged. The sealing ring 1213 slides in the opposite direction under the action of the return spring 1214, retracting the multiple connecting rods 1211 into the air chamber 121, achieving rapid depressurization and retraction, and improving operational efficiency.

[0036] like Figure 4 and Figure 5 As shown, in one embodiment, a leakage groove 1217 is provided on the periphery of the vent 1215. When the air-sealing cover 1216 is fastened to the vent 1215, the gas in the air chamber 121 is discharged through the leakage groove 1217.

[0037] In this embodiment, even if the air-sealing cover 1216 is not fully opened, gas can still be slowly discharged through the air leakage groove 1217, preventing excessive gas pressure in the air chamber 121. This improves the safety and reliability of the system and prevents component damage due to excessive pressure.

[0038] like Figure 4 and Figure 5 As shown, in one embodiment, a torsion spring 1218 is provided on the rotating shaft of the air-sealing cover 1216, and the torsion spring 1218 is used to drive the air-sealing cover 1216 to separate from the vent 1215.

[0039] In this embodiment, when the gas pressure decreases, the torsion spring 1218 drives the air-sealing cover 1216 to automatically open the vent 1215 and deflect it toward the air inlet of the gas chamber 121, accelerating the discharge of high-pressure gas from the gas chamber 121. This achieves automatic control of the air-sealing cover 1216 and improves the system's response speed.

[0040] like Figure 1 and Figure 2 As shown, in one embodiment, an image acquisition unit 123 is provided at the second end of the support rod 120, and a display unit 170 is provided on the powder spraying frame 100. The display unit 170 is used to display the image captured by the image acquisition unit 123.

[0041] In this embodiment, due to the height of the date palm tree, it is difficult to aim the pollen at the target female inflorescence by visual inspection alone. The image acquisition unit 123 is used to acquire the inflorescence position in real time, and the display unit 170 makes it easier to adjust the pollen spraying position.

[0042] like Figure 2 and Figure 3 As shown, in one embodiment, the tapered inclined surface 122 is provided with a slide rail groove 1221 along the generatrix direction, and the connecting rod 1211 is slidably disposed in the slide rail groove 1221.

[0043] In this embodiment, a slide rail groove 1221 is formed on the conical inclined surface 122 along the generatrix direction. The slide rail groove 1221 guides the connecting rod 1211 to unfold along a predetermined trajectory, ensuring the stability of the unfolded structure. This improves the guidance and structural stability during the unfolding process.

[0044] like Figure 1 As shown, in one embodiment, the support rod 120 is a telescopic rod.

[0045] In this embodiment, the first end of the telescopic rod is connected to the powder spraying frame 100 via a threaded structure, facilitating the replacement of the support rod 120 according to the tree height. The lengths of both the pollen delivery hose 140 and the air delivery pipe 150 are greater than the maximum length of the telescopic rod. The support rod 120 can be adjusted in length according to the tree height to adapt to pollination needs at different heights. This enhances the adaptability and flexibility of the device and expands its application range.

[0046] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
