Description

Technical Field

[0001] This utility model relates to the field of rice hybridization, and more specifically, to a rice hybridization pollination auxiliary device. Background Technology

[0002] Hybrid rice refers to the first generation of hybrid rice produced by crossing two rice varieties that have certain genetic differences and whose excellent traits can complement each other. Generally, hybrid rice refers only to the first generation of hybrid rice formed by crossing two sterile lines and restorer lines with the same genetic background. In order to increase grain yield, rice is usually pollinated.

[0003] Currently, pollination of hybrid rice can be carried out using mechanical pollination and manual pollination. Mechanical pollination methods, such as drone pollination and large-scale mechanical pollination, have the disadvantages of high cost and complex operation, which are a heavy cost burden for growers and difficult to operate, making them unsuitable for conventional growers. The most common, lowest cost, and most convenient traditional manual pollination method is rope pollination. By pulling the rope, the male rice ears collide with each other to achieve assisted pollination. During the process of pulling the rope, the contact between the rope and the male rice ears is only a frontal inertial contact. After one contact and collision, the rope returns to its original position, resulting in less pollen being stirred up and the pollination effect being unsatisfactory. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a rice hybrid pollination auxiliary device, including an inclined and hollow operating tube, a reciprocating connecting shaft inside the operating tube, a gripping rod at the top of the operating tube, and a transmission cavity with internal interconnection connected to the bottom of the operating tube. A pollination mechanism for stirring rice ears is provided below the transmission cavity. A driving component is provided inside the transmission cavity, which connects the pollination mechanism and the connecting shaft. The reciprocating movement of the connecting shaft drives the pollination mechanism to rotate below the operating tube through the driving component. A pull rod is provided near the top of the operating tube to pull the connecting shaft, and the pull rod passes through the operating tube and is connected to the connecting shaft.

[0005] In a preferred embodiment, at least two limiting tubes are embedded inside the operating tube, and the coupling is inserted into the limiting tube and moves back and forth inside the limiting tube.

[0008] In a preferred embodiment, the bottom end of the coupling has a driving surface facing the first gear, and teeth that mesh with the first gear are installed on the driving surface.

[0009] In a preferred embodiment, the bottom of the second helical gear is connected to a second connecting rod, and a limiting sleeve that penetrates the transmission cavity is sleeved on the outside of the second connecting rod.

The inner ring of the second bearing is fixedly connected to the second connecting rod, and the outer ring of the second bearing is fixedly connected to the limiting sleeve. The second helical gear meshes with the first helical gear.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0024] like Figure 1-5 The rice hybrid pollination auxiliary device shown includes an inclined and hollow operating tube 1, a reciprocating connecting shaft 2 inside the operating tube 1, a gripping rod 3 at the top of the operating tube 1, and a transmission cavity 4 connected to each other at the bottom of the operating tube 1. A pollination mechanism for moving rice ears is located below the transmission cavity 4. A driving component is located inside the transmission cavity 4, which connects the pollination mechanism and the connecting shaft 2. The reciprocating movement of the connecting shaft 2 drives the pollination mechanism to rotate below the operating tube 1 through the driving component. A pull rod 5 is located near the top of the operating tube 1 to pull the connecting shaft 2, and the pull rod 5 passes through the operating tube 1 and is connected to the connecting shaft 2.

[0025] Based on the above, when using it, the user holds the handle 3 with one hand and the pull rod 5 with the other hand. By pulling the pull rod 5 back and forth, the connecting shaft 2 moves back and forth inside the operating tube 1. The driving component drives the pollination mechanism to rotate below the transmission cavity 4, making contact with the rice ears and causing the pollen to be lifted to complete the pollination. This solves the problem of the traditional rope having too low a contact frequency and unsatisfactory pollination.

[0026] At least two limiting tubes 6 are embedded inside the operating tube 1, and the connecting shaft 2 is inserted into the limiting tube 6 and moves back and forth inside the limiting tube 6.

[0027] A limit baffle 7 is installed inside near the top of the operating tube 1. A return spring 8 is connected to the downward-facing side of the limit baffle 7, and the other end of the return spring 8 is connected to the top of the connecting shaft 2.

[0028] Based on the above, the connecting shaft 2 slides within the two limiting tubes 6 embedded inside the operating tube 1, ensuring the straightness and stability of the movement path. When the pull rod 5 is released, the return spring 8 automatically pushes the connecting shaft 2 back to its initial position, achieving continuous operation.

[0029] The driving component includes a first gear 9, a first helical gear 10 and a second helical gear 11 located inside the transmission cavity 4. A first connecting rod 12 is connected between the first gear 9 and the second helical gear 11. A first bearing 13 is sleeved on the outside of the first connecting rod 12. A fixing rod 14 is fixed on the outer ring of the first bearing 13. The end of the fixing rod 14 is fixed on the inner wall of the transmission cavity 4.

[0030] The first bearing 13, which is sleeved on the outside of the first connecting rod 12, is fixed to the inner wall of the transmission cavity 4 by the fixing rod 14 to ensure the smoothness of gear transmission and avoid meshing failure due to vibration.

[0031] The bottom end of the connecting shaft 2 is provided with a driving surface 15 facing the first gear 9, and teeth 16 that mesh with the first gear 9 are installed on the driving surface 15.

[0032] Based on the above, the bottom end of the connecting shaft 2 is designed with a driving surface 15, on which teeth 16 are mounted to mesh with the first gear 9 inside the transmission cavity 4. The forward and backward movement of the connecting shaft 2 drives the first gear 9 to reciprocate through the teeth 16.

[0033] The bottom of the second helical gear 11 is connected to a second connecting rod 17. The second connecting rod 17 is fitted with a limiting sleeve 18 that penetrates the transmission cavity 4. The second connecting rod 17 extends to the bottom of the transmission cavity 4 through the limiting sleeve 18 and is connected to the pollination mechanism.

[0034] Based on the above, the first gear 9 is connected to the first helical gear 10 via the first connecting rod 12, and the first helical gear 10 meshes perpendicularly with the second helical gear 11. This design converts the linear motion of the connecting shaft 2 into the vertical rotational motion of the second helical gear 11.

[0035] A second bearing 19 is installed at the top of the limiting sleeve 18 located inside the transmission cavity 4. The inner ring of the second bearing 19 is fixedly connected to the second connecting rod 17, and the outer ring of the second bearing 19 is fixedly connected to the limiting sleeve 18. The second helical gear 11 meshes with the first helical gear 10.

[0036] The second connecting rod 17 and the limiting sleeve 18 are inclined to the transmission cavity 4.

[0037] Based on the above, the second connecting rod 17 connected to the bottom of the second helical gear 11 passes through the transmission cavity 4 and achieves rotational freedom through the second bearing 19 (the inner ring is fixed to the second connecting rod 17, and the outer ring is fixed to the limiting sleeve 18). The limiting sleeve 18 is inclined to the transmission cavity 4, so that the pollination mechanism can contact the rice ears at the optimal angle.

[0038] The pollination mechanism includes a turntable 20 fixed at the bottom of the second connecting rod 17. Several pollination rods 21 arranged radially are connected to the outer wall of the turntable 20. The pollination rods 21 are covered with a sponge sleeve 22.

[0039] Based on the above, when the second connecting rod 17 rotates, the turntable 20 drives the pollination rod 21 to move the rice ears in a circular motion. The flexibility of the sponge sleeve 22 not only protects the rice ears from mechanical damage, but also fully lifts and attaches pollen through friction.

[0040] The tilted design of the operating tube 1 allows users to adjust the holding angle according to the height of the rice plants, ensuring that the pollination mechanism makes precise contact with the rice ears.

[0041] The outer wall of the operating tube 1 is provided with a groove 23 extending axially along the operating tube 1. The pull rod 5 passes through the operating tube 1 through the groove 23 and is fixedly connected to the connecting shaft 2. A baffle 24 is provided on the outer side of the groove 23 and fits against the outer wall of the operating tube 1. The baffle 24 is arc-shaped and its length is at least twice that of the groove 23. The baffle 24 is fixedly connected to the pull rod 5.

[0042] Based on the above, when in use, the user pulls the lever 5 to move it back and forth in the groove 23, thereby driving the connecting shaft 2 to move back and forth in the operating tube 1, driving the pollination mechanism to rotate and carry out pollination operations. The baffle 24 partially blocks the exposed groove 23 to prevent external debris from entering the interior of the operating tube 1.

[0043] Furthermore, the reciprocating motion of lever 5 directly inputs power, eliminating the need for electricity or fuel, reducing the electrical structure and overall weight of the equipment. The lightweight design allows it to be used flexibly in various terrains such as paddy fields, terraced fields, and slopes, without the need for leveling the land or fixed installation. Farmers do not need to master complex equipment operation skills; they can get started with simple training.

[0044] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
