Description

Technical Field

[0001] This utility model relates to the field of corn breeding pollination technology, specifically a corn pollinator. Background Technology

[0002] Maize is an annual herbaceous plant belonging to the genus Zea in the family Poaceae. It is an important food and feed crop, and one of the world's highest-yielding crops. A maize pollinator is a specialized tool used in maize hybridization breeding to accurately collect pollen from the male parent and efficiently transfer it to the silks of the female parent. Its core function is to replace or assist in direct artificial pollination, improving the efficiency and accuracy of hybridization pollination.

[0003] Existing pollinators for corn breeding often use a diffusion spraying method for pollination, which lacks a protective pollination function. Pollen is easily dispersed by wind, causing pollen and silks to fall off and affecting the pollination effect.

[0004] Therefore, a pollinator for maize breeding is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a pollinator for maize breeding to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pollinator for corn breeding, comprising a pollinator, wherein a pollen storage cylinder is connected to the outer wall of the pollinator; A pollination unit is located inside a pollinator and extends to the outside of the pollinator. The pollination unit includes a pollination component and a protective component. The pollination component can pollinate maize breeding, and the protective component is used to cooperate with the pollination component to achieve protective pollination. The pollen conveying unit is located inside the pollen storage cylinder and extends to the outside of the pollen storage cylinder. The pollen conveying unit is used to suppress the pollen inside the pollen storage cylinder, so that the pollen storage cylinder can stably deliver pollen to the inside of the pollinator. Under the restriction of the pollen conveying unit, the pollen storage cylinder and the pollinator can be used for protective pollination of maize breeding. Under the restriction of the pollen conveying unit, the pollen can be stably delivered to the inside of the pollinator, avoiding pollen from adhering to the inner wall of the pollen storage cylinder.

[0007] Preferably, the pollination component includes a push tube, the bottom of which is connected to a first square rod, and a spring is sleeved on the outer wall of the first square rod.

[0008] Preferably, the protective assembly includes a connecting frame, with a compression ring connected to the top of the connecting frame, a connecting block connected to the top of the pollinator, an arc plate hinged to the outer wall of the connecting block, a first magnetic block connected to the outer wall of the arc plate, a first L-shaped plate connected to the outer wall of the pollinator, and a second magnetic block connected to the inner side of the first L-shaped plate, wherein the first magnetic block and the second magnetic block are magnetically repelled.

[0009] Preferably, the outer wall of the push tube is slidably disposed with the inside of the pollinator, and the top of the push tube is concave. Under the constraint of the ejected push tube, the adhesion between pollen and filament can be enhanced.

[0010] Preferably, the outer wall of the extrusion ring is slidably disposed on the side of the arc plate away from the first magnetic block. There are eight arc plates, which are distributed circumferentially around the center of the top surface of the pollinator. When the arc plate is not squeezed by the extrusion ring, it can be pushed by the magnetic repulsion between the first and second magnetic blocks, and the eight arc plates close, providing a closed environment for filament pollination.

[0011] Preferably, one end of the spring is connected to the bottom of the push tube, and the end of the spring away from the push tube is connected to the bottom surface inside the pollinator. Under the elastic action of the spring, ejection pollination can be achieved through the push tube.

[0012] Preferably, the powder conveying unit includes a second L-shaped plate, a second square rod is slidably connected inside the second L-shaped plate, and a pressure plate is connected to the end of the second square rod.

[0013] Preferably, the outer wall of the pressure plate is slidably connected to the inside of the powder storage cylinder, and the end of the second L-shaped plate is connected to the top of the powder storage cylinder. Under the action of the pressure plate's own weight, the pollen inside the powder storage cylinder can be pressed and transported.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. In this invention, during pollination, pollen is added to a pollen storage cylinder. Pushing the first square rod upwards moves the push tube upwards, pulling the spring while simultaneously pushing the compression ring upwards via a connecting frame. This compresses the arc plate, causing it to rotate and open. After the filament is inserted, the first square rod is released, and the spring pulls the push tube, connecting frame, and compression ring downwards. The arc plate, under the repulsive force of the magnetic block, returns to its original position and closes, enveloping the filament. Pulling down the first square rod compresses the spring, opening the channel for the push tube. The pollen conveying unit delivers pollen to the top of the push tube. Releasing the spring lifts the push tube, causing the pollen to bounce towards the filament and enhance adhesion. The closed arc plate prevents wind and scattering. After pollination, pushing the first square rod upwards opens the arc plate, allowing it to be removed. This structure, through arc plate protection and projectile pollination, enhances the adhesion between pollen and filament. 2. In this utility model, when adding pollen, the second square rod is pulled to disengage the pressure plate from the pollen storage cylinder. After adding pollen, the rod is released, and the pressure plate presses the pollen with its own weight. When the push tube opens the channel, the gravity of the pressure plate presses the pollen into the pollinator, avoiding pollen adhering to the cylinder wall and causing uneven pollination, thus achieving stable pollen delivery.

[0022] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0023] Example 1 Reference Figure 1 and Figure 2 This is the first embodiment of the present utility model. This embodiment provides a pollinator for corn breeding, including a pollinator 1, and a powder storage cylinder 2 is connected to the outer wall of the pollinator 1. Pollination unit 3 is placed inside pollinator 1 and extends to the outside of pollinator 1. Pollination unit 3 includes a pollination component and a protective component. The pollination component can pollinate corn for breeding, and the protective component is used to cooperate with the pollination component to achieve protective pollination. Pollen conveying unit 4 is placed inside the pollen storage cylinder 2 and extends to the outside of the pollen storage cylinder 2. The pollen conveying unit 4 is used to press the pollen inside the pollen storage cylinder 2 so that the pollen storage cylinder 2 can stably convey pollen into the pollinator 1.

[0024] When in use, under the restriction of pollination unit 3, pollination for corn breeding can be carried out through pollen storage cylinder 2 and pollinator 1. Under the restriction of pollen conveying unit 4, pollen can be stably conveyed inside pollinator 1 to prevent pollen from adhering to the inner wall of pollen storage cylinder 2.

[0025] Example 2 Reference Figure 3 and Figure 4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiment, as follows: The pollination assembly includes a push tube 31, with a first square rod 32 connected to the bottom of the push tube 31. A spring 33 is sleeved on the outer wall of the first square rod 32. The protective assembly includes a connecting frame 34, with a compression ring 35 connected to the top of the connecting frame 34. A connecting block 36 is connected to the top of the pollinator 1. An arc plate 37 is hinged to the outer wall of the connecting block 36. A first magnetic block 38 is connected to the outer wall of the arc plate 37. A first L-shaped plate 39 is connected to the outer wall of the pollinator 1. A second magnetic block 310 is connected to the inner side of the first L-shaped plate 39. The first magnetic block 38 and the second magnetic block 310 are magnetically repelled.

[0026] The outer wall of the push tube 31 is slidably disposed with the inside of the pollinator 1, and the top of the push tube 31 is concave. Under the constraint of the ejected push tube 31, the adhesion between pollen and filament can be enhanced.

[0027] The outer wall of the extrusion ring 35 is slidably disposed on the side of the arc plate 37 away from the first magnetic block 38. There are eight arc plates 37, which are distributed in a circle around the center of the top surface of the pollinator 1. When the arc plate 37 is not squeezed by the extrusion ring 35, it can be pushed by the magnetic repulsion between the first magnetic block 38 and the second magnetic block 310, and the eight arc plates 37 close, providing a closed environment for filament pollination.

[0028] One end of the spring 33 is connected to the bottom of the push tube 31, and the other end of the spring 33 away from the push tube 31 is connected to the bottom surface inside the pollinator 1. Under the elastic action of the spring 33, the pollinator can be ejected through the push tube 31.

[0029] When pollinating corn, pollen is added to the pollen storage cylinder 2. The first square rod 32 is pushed upward, causing the push tube 31 to move upward as well. The push tube 31 pulls on the spring 33 fixedly installed at its bottom. Since the push tube 31 is fixedly installed on the compression ring 35 through the connecting frame 34, under its constraint, the push tube 31 pushes the compression ring 35 upward. At this time, the outer wall of the compression ring 35 and the side of the arc plate 37 away from the first magnetic block 38 are squeezed, causing the arc plate 37 to rotate around the hinge point with the connecting block 36 as the rotation center, so that the corn breeding silk is sleeved into the pollinator 1. The first square rod 32 is released, and under the pull of the spring 33, the push tube 31, the connecting frame 34 and the compression ring 35 are pulled downward. At this time, the compression ring 35 no longer squeezes the arc plate 37. Under the restriction of the magnetic repulsion between the first magnetic block 38 and the second magnetic block 310, the arc plate 37 can be reset and pushed. Multiple sets of arc plates 37 close, thus wrapping the silk inside the pollinator 1. At this point, pulling down the first square rod 32 compresses the spring 33 through the push tube 31. When the outer wall of the push tube 31 no longer obstructs the connection between the pollen storage cylinder 2 and the pollinator 1, it can cooperate with the pollen conveying unit 4 to transport pollen upwards through the push tube 31. Releasing the first square rod 32 then causes the push tube 31 to spring up under the elastic action of the spring 33, causing the pollen above the push tube 31 to spring up and adhere to the surface of the filament. The multiple sets of closed arc plates 37 prevent pollen from being dispersed by external wind. After pollination, pushing the first square rod 32 upwards causes the extrusion ring 35 to open the arc plates 37, allowing the pollinator 1 to be removed from the outside of the filament. This structure uses multiple sets of closed arc plates 37 to protect the filament during pollination, and combined with the ejector pollination method, it can enhance the adhesion between pollen and filament.

[0030] Example 3 Reference Figure 5 and Figure 6 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiments, as detailed below: The powder conveying unit 4 includes a second L-shaped plate 41, a second square rod 42 is slidably connected inside the second L-shaped plate 41, and a pressure plate 43 is connected to the end of the second square rod 42.

[0031] The outer wall of the pressure plate 43 is slidably connected to the inside of the powder storage cylinder 2, and the end of the second L-shaped plate 41 is connected to the top of the powder storage cylinder 2. Under the action of the pressure plate 43's own weight, the pollen inside the powder storage cylinder 2 can be pressed and transported.

[0032] When pollinating corn silks, pull the second square rod 42 to disengage the pressure plate 43 from the pollen storage cylinder 2, allowing pollen to be added into the cylinder 2. Release the second square rod 42, and under the weight of the second square rod 42 and the pressure plate 43, the pollen inside the cylinder 2 is pressed down. When the push tube 31 no longer obstructs the connection between the pollen storage cylinder 2 and the pollinator 1, the pollen inside the cylinder 2 can be pressed and transported into the pollinator 1 under the gravity of the pressure plate 43, preventing pollen from adhering to the inner wall of the cylinder 2. This structure can stably transport pollen into the pollinator 1, avoiding pollen adhesion and uneven pollination.

Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
