Description

Technical Field

[0001] The utility model relates to the technical field of fruit tree pollination, in particular to a fruit tree pollination device. Background Art

[0002] Artificial pollination refers to the use of artificial methods to transfer plant pollen to the stigma to increase fruit set. In fruit tree production, artificial pollination is often required for fruit trees that do not self-pollinate, when there is a lack of pollinating trees or when the weather during the flowering period is harsh, affecting normal natural pollination. The general method of artificial pollination is to place processed pollen into a dry vial, use an eraser-tipped pencil or goose feather stick to dip a little pollen, and gently tap it onto the newly opened stigma. This method has a high fruit set rate, but it is time-consuming and labor-intensive, and the amount of pollen collected each time is uncertain, resulting in uneven pollination for each flower. Furthermore, the optimal pollination period for fruit trees is only a few days during flowering. If artificial pollination is required on a large scale, it consumes a lot of manpower and material resources, increasing production costs.

[0003] Patent document CN208191730U discloses a push-type fruit tree pollinator. During use, the pollination hood is detachably mounted on the pollen storage tube. To do this, the pollination hood, sealing ring, and pollination tray are first removed, ensuring the pressure head is inside the pollen storage tube. The tube is then inverted, with the pressure head's push handle positioned below the tube. Pollen is then added, the pollination hood, sealing ring, and pollination tray are installed, and the tube is inverted. The push handle is then pushed to directly pollinate the flower. This pollinator can only pollinate one fruit tree flower at a time, resulting in low efficiency and making it inconvenient to pollinate flowers in high locations.

[0004] The patent document with publication number CN209201772U discloses a handheld fruit tree pollination device. When in use, the prepared fruit tree pollen is poured into a pollen storage bottle, the pollen storage bottle is threadedly connected to the pollination inlet on the pollination tube, and the pollination tube is adjusted to a suitable angle so that the pollen in the pollen storage bottle enters the pollen outlet bin. When the pollen reaches the required amount, the pollination tube angle is adjusted so that the pollen storage bottle is located below the pollination tube. One hand holds the handle and places the pollination cover on the flower to be pollinated. The other hand squeezes the air bag, and the gas enters the air supply pipe and blows the pollen in the pollen outlet bin out and falls onto the stamens through the gauze. When using this pollination device, it is necessary to frequently adjust the angle of the pollination tube so that the pollen in the pollen storage bottle enters the pollen outlet bin. The pollination operation efficiency is low, and it is impossible to ensure the effective spraying of pollen, which easily leads to pollination failure. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a fruit tree pollination device which is easy to use, can ensure the effective spraying of pollen, and can improve the success rate of pollination.

[0006] In order to achieve the above purpose, the technical solution provided by the utility model is:

One end of the cannula in the branch pipe is connected to the branch pipe, and one end of the cannula outside the branch pipe is blocked. A U-shaped bracket is fixed to one end of the cannula outside the branch pipe, and a storage tank is rotatably arranged in the bracket. A counterweight ring is concentrically fixed to the lower end of the storage tank. A nozzle is fixed on the bracket. The upper part of the storage tank is connected to the cannula through an inlet pipe, and the lower end of the storage tank is connected to the nozzle through an outlet pipe. Both the inlet pipe and the outlet pipe are hoses.

[0008] Specifically, the inlet end and the outlet end of the airbag are fixedly connected to the two ends of the bracket respectively.

[0009] Specifically, the upper end of the storage tank is open, and a cover is detachably fixedly and sealedly connected to the upper end of the storage tank.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This device sets a rotatable storage tank in the bracket, and a counterweight ring is fixed at the lower end of the storage tank.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Example 1: Reference Figures 1-4 As shown, a fruit tree pollination device includes an inverted U-shaped bracket 1, in which an air bag 2 is fixed. The inlet and outlet ends of the air bag 2 are respectively fixedly connected to the two ends of the bracket 1. A one-way air inlet valve 3 and a one-way air exhaust valve 4 are respectively installed at the inlet and outlet ends of the air bag 2.

[0025] When airbag 2 is squeezed, one-way air inlet valve 3 closes and one-way air outlet valve 4 opens, allowing air inside airbag 2 to be discharged from the outlet. After airbag 2 is released, it returns to its original position due to its elasticity. When airbag 2 returns to its original position, one-way air outlet valve 4 closes and one-way air inlet valve 3 opens, allowing air outside airbag 2 to enter through the inlet.

[0026] A branch pipe 5 is fixed on the bracket 1, and the outlet end of the airbag 2 is connected to the branch pipe 5. A cannula 8 is inserted into the branch pipe 5 in a sliding and sealing manner. There is sliding damping between the branch pipe 5 and the cannula 8. One end of the cannula 8 inside the branch pipe 5 is connected to the branch pipe 5, and one end of the cannula 8 outside the branch pipe 5 is blocked.

[0027] A U-shaped bracket 9 is fixed to one end of the cannula 8 outside the branch pipe 5, and a storage tank 10 is rotatably arranged in the bracket 9. Specifically, the storage tank 10 is rotatably connected to the bracket 9 via a rotating shaft, and the axial direction of the rotating shaft is perpendicular to the axial direction of the cannula 8. The upper end of the storage tank 10 is open, and the upper end of the storage tank 10 is detachably fixed and sealed with a cover. A counterweight ring 11 is concentrically fixed to the lower end of the storage tank 10. A nozzle 14 is fixed to the bracket 9. The upper part of the storage tank 10 is connected to the cannula 8 via an inlet pipe 13, and the lower end of the storage tank 10 is connected to the nozzle 14 via an outlet pipe 12. Both the inlet pipe 13 and the outlet pipe 12 are hoses.

[0028] The nozzle 14 includes a straight section and an inclined section. The straight section of the nozzle 14 is parallel to the cannula 8. The nozzle 14 is blocked at one end close to the bracket 9. A cover 15 is fixed to the outlet end of the nozzle 14.

[0029] When the airbag 2 is pressed, the air in the airbag 2 enters the storage tank 10 through the branch pipe 5, the insertion pipe 8, and the inlet pipe 13. The air entering the storage tank 10 carries the pollen in the storage tank 10 and is ejected in sequence through the outlet pipe 12, the nozzle 14, and the cover 15. The pollen ejected from the cover 15 falls on the pistil of the flower, completing pollination.

[0030] After the angles of the branch pipe 5, the insert pipe 8 and the nozzle 14 are conveniently changed, under the action of the counterweight ring 11, the axis of the storage tank 10 is always perpendicular to the horizontal plane. After the air enters the storage tank 10, it can ensure that the pollen in the storage tank 10 flows through the outlet pipe 12, the nozzle 14 and the cover body 15 and is effectively discharged, which can improve the success rate of pollination.

[0031] The insert tube 8 can slide in the branch tube 5, so it is convenient to adjust the height of the nozzle 14 and to pollinate flowers high up on the fruit trees.

[0032] Example 2: Based on Example 1, refer to Figure 1 、 Figure 3 and Figure 4 As shown, a gas volume regulating assembly is provided on the side of the branch pipe 5 close to the bracket 1. The gas volume regulating assembly includes a slot 6 opened on the branch pipe 5, and a sliding sealing sleeve on the branch pipe 5 is provided with a rubber sleeve 7, which can control the opening of the slot 6.

[0033] After pressing the airbag 2, part of the air is discharged through the slot 6, and the other part of the air enters the storage tank 10 through the branch pipe 5, the insert pipe 8 and the inlet pipe 13. The opening of the slot 6 can be adjusted by the rubber sleeve 7. When the airbag 2 is pressed, the amount of air discharged from the slot 6 can be changed, and then the amount of air entering the storage tank 10 can be changed, and finally the amount of pollen sprayed can be adjusted.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
