Description

Technical Field

[0001] This invention relates to the field of fruit tree pollination technology, specifically a pollen dispersing device for fruit trees. Background Technology

[0002] Pollination of fruit trees is one of the key steps in fruit tree propagation, and the method and efficiency of pollen dispersal directly affect the fruit set rate and fruit quality. Traditional pollination methods mainly rely on natural factors such as insects and wind for pollination, but this method is greatly affected by environmental and climatic factors, resulting in unstable pollination effects.

[0003] Currently, some pollen dispersing devices for fruit trees are available on the market. These devices typically use sprayers, spray guns, or other tools to spray pollen onto the fruit trees. However, these devices have some shortcomings. They cannot adjust the amount and area of ​​pollen dispersal based on the density and area of ​​the fruit tree's flowers.

[0004] To address the aforementioned problems, this invention provides a pollen dispersing device for fruit trees. This device, by incorporating a pollen ejection mechanism and a selective sealing mechanism, can spray pollen at a single point or multiple points using a specific channel design, allowing for selective application based on the pollen dispersal area. The high-pressure air ejection mechanism utilizes the instantaneous ejection of high-pressure air to propel the pollen, ensuring uniform pollination of the fruit tree flowers.

[0030] Please see Figure 1-7 A pollen dispersing device for fruit trees includes an outer cover 1, an external fixed connection mounting sleeve 2 to the outer cover 1, and a hand handle 3 fixedly connected to the mounting sleeve 2; a spray plate 6 and a back plate 7 are fixedly connected to the inner two ends of the outer cover 1 respectively, a threaded seat 8 is fixedly provided on the back plate 7, a pollen can 4 is threadedly connected to the inner side of the threaded seat 8, and a pollen spraying mechanism and a high-pressure air spraying mechanism are provided inside the outer cover 1.

[0031] The pollen ejection mechanism includes a spherical cover 12 disposed inside the outer cover 1. An independent pollen ejection pipe 15 is fixedly connected between the spherical cover 12 and the ejection plate 6. An independent pollen ejection hole 16 connected to the independent pollen ejection pipe 15 is opened on the ejection plate 6. Multiple pollen ejection branch pipes 13 are provided on the outside of the independent ejection branch pipes. The two ends of the pollen ejection branch pipes 13 are fixedly connected to the spherical cover 12 and the ejection plate 6 respectively. A pollen ejection branch hole 14 connected to the pollen ejection branch pipe 13 is opened on the ejection plate 6. A pollen storage tube 18 is fixedly connected to the bottom end of the spherical cover 12. A pollen guide 21 is fixedly connected to the side of the back plate 7 located inside the outer cover 1. The pollen guide 21 is connected to the pollen tank 4. A pollen delivery pipe 20 is fixedly connected between the pollen guide 21 and the pollen storage tube 18.

[0032] The high-pressure air ejection mechanism includes a closed baffle 26 fixedly installed inside the outer cover 1. A high-pressure chamber is provided inside the outer cover 1 between the closed baffle 26 and the back plate 7. The closed baffle 26 has a main exhaust port 38 and a secondary exhaust port. A pressure pipe 19 is fixedly connected between the secondary exhaust port and the pollen storage tube 18. A micro air pump 37 is provided on the back plate 7. The output end of the micro air pump 37 is connected to the high-pressure chamber. A drive motor 29 is fixedly installed on the closed baffle 26. The output shaft of the drive motor 29 passes through the closed baffle 26 and is coaxially fixedly connected to the drive seat 30. A first arc-shaped rod 33 and a second arc-shaped rod 34 are fixedly connected to the outside of the drive seat 30. A first sealing block 31 corresponding to the position of the main exhaust port 38 is fixedly installed at the end of the first arc-shaped rod 33 away from the drive seat 30. A second sealing block 32 corresponding to the position of the secondary exhaust port is fixedly installed at the end of the second arc-shaped rod 34 away from the drive seat 30.

[0033] Furthermore, the coverage area of ​​the first sealing block 31 on the sealing baffle 26 is greater than the coverage area of ​​the second sealing block 32 on the sealing baffle 26. During the synchronous circular movement of the first sealing block 31 and the second sealing block 32, the second sealing block 32 first opens the auxiliary exhaust port, and then the first sealing block 31 opens the main exhaust port 38. The advantage of this design is that it ensures that there is enough high-pressure air to blow the pollen from the pollen storage tube 18 and move it.

[0034] The spherical cover 12 is provided with a selective closure mechanism, which is connected to the push-pull drive assembly.

[0035] The selective sealing mechanism includes an annular stop 24 rotatably connected to the inner wall of the spherical cover 12.

The annular stop 24 is located on one side of the multiple input branch holes, and the annular stop 24 has a connecting hole 25 corresponding to the input branch hole.

[0036] The push-pull drive assembly includes a push-pull rod 39 partially located inside the outer cover 1. The push-pull rod 39 has a straight toothed section 35 on its outer side. A drive gear 27 is provided on one side of the push-pull rod 39. The drive gear 27 has an arc-shaped toothed section 36 on its outer side near the push-pull rod 39. The drive gear 27 is coaxially and fixedly connected to a drive rod 22. The drive rod 22 extends into the spherical cover 12. The end of the drive rod 22 away from the drive gear 27 is fixedly connected to a plurality of connecting rods 23 between it and an annular stop seat 24.

[0037] The push-pull rod 39 has a slot inside one end of the outer cover 1. A return spring is fixedly connected in the slot. The return spring is fixedly connected to a fixing rod 28. The fixing rod 28 extends out of the slot and is fixedly connected to the inner wall of the outer cover 1.

[0038] The hand sleeve is hollow inside, and a groove 9 is provided on one side of the hand sleeve. The push-pull rod 39 extends into the hand sleeve and passes through the groove 9 to be placed outside. The push-pull rod 39 located outside the hand sleeve is fixedly connected to the push-pull handle 10.

[0039] The handheld lever 3 is fixedly connected to a guide seat 11, and the push-pull rod 39 passes through the guide seat 11 and is slidably connected to it.

[0040] The ejector plate 6 has multiple air jet holes 17 extending through it.

[0041] The outer cover 1 is fixedly connected to the horn cover 5 at one end of the ejector plate 6.

[0042] The handheld lever 3 is equipped with a storage battery, and a control button is located on the outside of the handheld lever 3. The storage battery is electrically connected to the control button, and the control button is electrically connected to the drive motor 29 and the micro air pump 37.

[0043] In the implementation of this invention, the pollen container 4 containing pollen is first threadedly connected to the threaded seat 8 to fix the pollen container 4 in place. By shaking the handle 3, the pollen inside the pollen container 4 can be moved, allowing the pollen to pass through the pollen guide shroud 21 into the pollen delivery pipe 20, and then into the pollen storage pipe 18. When it is necessary to disperse pollen into fruit trees, the following two methods can be used:

[0044] The first method is for pollinating small areas of flowers. Specifically, the drive motor 29 is started by controlling the control button. The drive motor 29 drives the drive base 30 to rotate, which in turn drives the first sealing block 31 and the second sealing block 32 to move through the first arc rod 33 and the second arc rod 34. At this time, high-pressure air can enter the pollen storage tube 18 through the air pressure pipe 19, and carry the pollen in the pollen storage tube 18 to the spherical cover 12, and then enter the independent outlet pipe. Finally, the pollen is carried by the airflow and sprayed out from the independent pollen outlet 16. On the other hand, the high-pressure air is discharged from the main exhaust port 38 and finally sprayed out from multiple jet holes 17, which provides power for the pollen to be sprayed out, and can also improve the uniformity of pollen dispersal under the disturbance of airflow.

[0045] The second method is for pollinating a large area of ​​flowers. Specifically, first, push the push-pull handle 10, which moves the push-pull rod 39. The straight tooth segment 35 moves along with the push-pull rod 39. During the movement of the straight tooth segment 35, it meshes with the arc-shaped tooth segment 36 on the outside of the drive gear 27, causing the driven gear to rotate. This causes the drive rod 22, connecting rod 23, and annular stop 24 to rotate at a certain angle, connecting the connecting hole 25 with the input support hole. The drive motor 29 is started by controlling the control button. The drive motor 29 drives the drive seat 30 to rotate, which in turn drives the first arc-shaped rod 33 and the second arc-shaped rod 34 to drive the first sealing block. 31 and the second sealing block 32 move. At this time, high-pressure air can enter the pollen storage tube 18 through the air pressure tube 19, and carry the pollen in the pollen storage tube 18 into the spherical cover 12, and then enter the independent outlet tube. Finally, some of the pollen enters the independent pollen outlet tube 15, and the other part of the pollen enters the multiple pollen outlet branches 13 evenly, thus achieving large-area dispersal. On the other hand, the high-pressure air is discharged from the main exhaust port 38 and finally sprayed out from multiple jet holes 17, providing power for the pollen spraying and improving the uniformity of pollen dispersal under the disturbance of airflow.

[0046] In addition, by limiting the inner diameter of the independent pollen outlet pipe 15 and the pollen outlet branch pipe 13, the amount of pollen ejected at one time can be controlled, thus avoiding excessive pollen ejection.

[0047] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
