Description

Technical Field

[0001] The present invention belongs to the technical field of corn pollination, and particularly relates to a pollinator for corn breeding. Background Art

[0002] Corn is an annual monoecious cross-pollinated plant with tall plants and strong stems. It is an important food crop and feed crop, and also the crop with the highest total yield in the world. Its planting area and total yield are second only to rice and wheat.

[0003] As anemophilous pollinated plant, the natural pollination of corn depends on the wind to transfer the pollen produced by the male inflorescence to the stigma of the female inflorescence. After the anthers of the male inflorescence mature, they crack, and the pollen drifts with the wind. The diffusion of pollen under the action of wind makes the pollination of corn affected by the wind. If the wind is small, it is necessary to manually shake multiple corn stalks to simulate the wind to help the pollen scatter. However, in order to save manpower, the manual shaking time of each corn stalk in the corn stalk group is short, and insufficient shaking force will cause poor pollen scattering, thus resulting in poor pollination effect of the device on corn. Summary of the Invention

[0004] The purpose of the present invention is to provide a pollinator for corn breeding to solve the problem that the existing manual shaking time of each corn stalk in the corn stalk group is short, and insufficient shaking force will cause poor pollen scattering, thus resulting in poor pollination effect of the device on corn.

The square cylinder fixedly connected to the upper part of the outer surface of the piston rod is communicated with the inside of the piston cylinder. A group of second one-way valves and a fan are inlaid on the outer surface of the square cylinder.

[0009] As a further description of the above technical solution:

The air inlet end of the third one-way valve is communicated with the outside, and the air outlet end of the third one-way valve and the air inlet end of the second one-way valve are both communicated with the inside of the square cylinder. The air outlet end of the second one-way valve is communicated with the outside.

[0011] As a further description of the above technical solution:

[0012] The through pipe fixedly communicated with the air inlet end of the first one-way valve extends to the upper part of the inner bottom wall of the pollen box, and the air outlet end of the first one-way valve is communicated with the inside of the piston cylinder. A rubber plug is clamped on the upper surface of the pollen box.

[0013] As a further description of the above technical solution:

[0014] A sliding groove is provided on the inner wall of the top cylinder. The slider slidably connected to the inner wall of the sliding groove is fixedly connected to the outer surface of the straight cylinder. The telescopic spring fixedly connected to the outer surface of the slider is fixedly connected to the inner wall of the sliding groove.

[0015] As a further description of the above technical solution:

[0016] A first protective shell is fixedly connected to the outer surface of the second motor. The outer surface of the eccentric wheel is not in contact with the inner walls of the first protective shell and the top cylinder. The straight cylinder is slidably connected to the inner wall of the top cylinder. The liquid inlet end of the check valve is communicated with the outside, and the liquid outlet end of the check valve is communicated with the inside of the straight cylinder.

The humidified silk is also more likely to adsorb pollen, increasing the pollination effect of the device on corn. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1-6 , the present invention provides a technical solution: a pollinator for corn breeding, including a straight tube 1, a top tube 2 slidably connected to both ends of the straight tube 1, and two straight rods 3 arranged outside the straight tube 1. Handles 30 are fixedly connected to the outer surfaces of the straight rods 3 and the piston cylinder 4. The arrangement of the handles 30 facilitates the grasping of the straight rods 3. The inner wall of the straight tube 1 is slidably connected to the inner wall of the top tube 2. A chute 16 is provided on the inner wall of the top tube 2. A slider 17 slidably connected to the inner wall of the chute 16 is fixedly connected to the outer surface of the straight tube 1. A telescopic spring 18 fixedly connected to the outer surface of the slider 17 is fixedly connected to the inner wall of the chute 16. Figure 3 and Figure 6 the telescopic springs 18 in are in a compressed state and a stretched state respectively. The cooperation of the chute 16 and the slider 17 plays a role in limiting the movement of both ends of the straight tube 1 inside the top tube 2. The arrangement of the telescopic spring 18 plays a role in buffering and resetting the movement of the slider 17 inside the chute 16. A piston rod 5 is slidably connected to the inner wall of a piston cylinder 4 fixedly connected to the upper end of the straight rod 3. The upper end of the piston rod 5 is fixedly connected to the top tube 2. A toothed ring 6 rotatably connected to the upper surface of the piston cylinder 4 is threadedly connected to a reciprocating thread 7 provided on the outer surface of the piston rod 5. And an output end of a first motor 8 arranged on the outer surface of the piston cylinder 4 is fixedly connected to a gear 9 meshing with the toothed ring 6. A second protective shell 28 is fixedly connected to the outer surface of the first motor 8. The toothed ring 6 and the gear 9 are both located inside the second protective shell 28. The gear 9 does not contact the inner wall of the second protective shell 28. The arrangement of the second protective shell 28 plays a role in protecting the gear 9 and preventing the influence of external factors on the operation of the gear 9. A group of abutting blocks 10 are fixedly connected to the outer surface of the straight tube 1. And a water-absorbing cotton 11 is clamped inside the straight tube 1. The arrangement of the abutting blocks 10 increases the vibration effect generated by the reciprocating movement of the straight tube 1 left and right on the corn stalks and corn cobs in contact with the straight tube 1.

[0033] The operation of the first motor 8 drives the gear 9 to rotate, causing the toothed ring 6 engaged with the gear 9 to rotate, thereby driving the piston rod 5 to reciprocate up and down inside the piston cylinder 4. While driving the top cylinder 2 and the straight cylinder 1 to vibrate up and down, the external air flows through the dust collection net 32, the pollen box 19, the through pipe 25, the first one-way valve 20, the piston cylinder 4, the square cylinder 21, the second one-way valve 22 and the fan 23 to the lower part of the straight cylinder 1. The air inside the pollen box 19 moves with the air flow to the corn stalks and corn cobs below the straight cylinder 1, increasing the amount of corn pollen, thereby enhancing the pollination effect. The operation of the second motor 14 drives the eccentric wheel 15 to rotate. The eccentric wheel 15 always contacts the two ends of the straight cylinder 1, causing the two ends of the straight cylinder 1 to move left and right inside the top cylinder 2, making the corn stalks or corn cobs in contact with the straight cylinder 1 vibrate left and right. The setting of the abutting block 10 enhances the vibration effect of the left and right movement. At the same time, the operation of the atomizing sheet 12 atomizes the water inside the straight cylinder 1 into small particle water mist, which settles downward to the lower part of the straight cylinder 1, better depositing the pollen particles on the filaments. Through the horizontal and vertical movements, the device enhances the vibration effect on the corn cobs. At the same time, with the cooperation of the water mist, the humidified filaments are also more likely to adsorb pollen, increasing the pollination effect of the device on corn.

[0034] A set of atomizing sheets 12 is fixedly connected to the lower part of the outer surface of the straight tube 1, and a check valve 13 connected to the inside of the straight tube 1 is inlaid on the left side of the outer surface of the straight tube 1. The atomizing sheet 12 is usually composed of a piezoelectric ceramic sheet and a metal film. Among them, the piezoelectric ceramic is the core functional material. This material has the inverse piezoelectric effect: when a high-frequency voltage is applied, the ceramic sheet will undergo mechanical deformation and generate high-frequency vibration. The atomizing sheet 12 receives a high-frequency electrical signal through a circuit. Under the action of an electric field, the piezoelectric ceramic sheet vibrates at this frequency, and electrical energy is converted into mechanical energy through the inverse piezoelectric effect, causing high-frequency resonance on the surface of the atomizing sheet 12. Electrical energy is converted into mechanical energy through the inverse piezoelectric effect, causing high-frequency resonance on the surface of the atomizing sheet 12. Under high-frequency vibration, the structure of liquid water molecules is broken, forming tiny particles with a diameter of 1-5 micrometers, thereby generating natural and floating water mist. The liquid inlet end of the check valve 13 is connected to the outside, and the liquid outlet end of the check valve 13 is connected to the inside of the straight tube 1. A through hole 29 is opened in the upper part of the outer surface of the straight tube 1. The opening of the through hole 29 makes the air pressure inside the straight tube 1 always the same as the outside air pressure, which is beneficial to adding water to the inside of the straight tube 1 and is also beneficial to the water inside the straight tube 1 better contacting the working end of the atomizing sheet 12 and being atomized. Atomization humidifies the pollen and slows down the phenomenon of pollen losing water in a dry environment. The humidified silk, which is the receptive structure of the ear, is more likely to adsorb pollen. The water mist can increase the water content in the air, making the pollen grains easier to settle on the silk. By atomizing water to increase humidity, the pollen lifespan can be extended, pollen scattering and adhesion can be promoted, and at the same time, the negative impact of high temperature on pollination can be reduced. The output end of the second motor 14 arranged on the outer surface of the top cylinder 2 is fixedly connected to an eccentric wheel 15 slidably connected to the straight tube 1. The eccentric wheel 15 is a circular disc-shaped part with the axis not coinciding with the geometric center. Through rotation, it realizes asymmetric linear or reciprocating motion, and uses the eccentricity (the distance between the axis and the geometric center) to generate periodic displacement changes during rotation, converting rotational motion into linear motion or swinging. The outer surface of the second motor 14 is fixedly connected to a first protective shell 27. The outer surface of the eccentric wheel 15 does not contact the inner walls of the first protective shell 27 and the top cylinder 2. The first protective shell 27 plays a protective role for the eccentric wheel 15, reducing the influence of external factors on the rotation of the eccentric wheel 15.

[0035] The pollen box 19 fixedly connected to the outer surface of the piston barrel 4 is connected to the inside of the piston barrel 4 through a first one-way valve 20. A one-way valve is a valve that allows fluid to flow in a single direction and prevents reverse flow. An observation window 31 is provided on the front surface of the pollen box 19, and a dust collection net 32 is fixedly connected to the inner bottom wall of the pollen box 19. The dust collection net 32 is a filtering component used in air purification or dust removal equipment. Its core function is to capture dust, particulate matter, and other pollutants in the air, thereby improving air quality. In this application, while utilizing the air permeability of the dust collection net 32, it prevents the pollen in the pollen box 19 from leaking out. The observation window 31 is a component used to provide a visual window in equipment, containers, or closed systems, allowing users to observe the internal state without damaging the system's airtightness. It isolates the internal and external environments through transparent materials (such as glass, plastic) while maintaining optical transparency to ensure clear observation. The setting of the observation window 31 facilitates observing the remaining amount of pollen inside the pollen box 19. The setting of the dust collection net 32 facilitates the entry of external air into the inside of the piston barrel 4 through the through pipe 25 and the first one-way valve 20, causing the corn pollen inside the pollen box 19 to move along with the airflow into the inside of the piston barrel 4. The through pipe 25 fixedly connected to the intake end of the first one-way valve 20 extends to the upper part of the inner bottom wall of the pollen box 19, and the outlet end of the first one-way valve 20 is connected to the inside of the piston barrel 4. A rubber plug 26 is clamped on the upper surface of the pollen box 19. The rubber plug 26 is a sealing member made of rubber material, with strong tear strength, high elongation rate, and good elasticity. It can closely fit the container to achieve reliable sealing. Appropriate amount of corn pollen can be added to the inside of the pollen box 19 by detaching the rubber plug 26 from the upper surface of the pollen box 19. The square barrel 21 fixedly connected to the upper part of the outer surface of the piston rod 5 is connected to the inside of the piston barrel 4. A group of second one-way valves 22 and a fan 23 are inlaid on the outer surface of the square barrel 21. The setting of the fan 23 increases the outflow of corn pollen inside the pollen box 19. A group of third one-way valves 24 are fixedly connected to the back surface of the square barrel 21. The intake end of the third one-way valve 24 is connected to the outside, and the outlet end of the third one-way valve 24 and the intake end of the second one-way valve 22 are both connected to the inside of the square barrel 21. The outlet end of the second one-way valve 22 is connected to the outside, ensuring the air flow direction inside the square barrel 21, that is, when the piston rod 5 moves up and down inside the piston barrel 4, the pollen inside the pollen box 19 flows to the outside through the through pipe 25, the first one-way valve 20, the piston barrel 4, the square barrel 21, and the second one-way valve 22, and the external air flows to the outside through the third one-way valve 24, the square barrel 21, the second one-way valve 22, and the fan 23, increasing the air flow rate inside the square barrel 21.

[0036] Working principle: When in use, add an appropriate amount of corn pollen into the interior of the pollen box 19, connect the first motor 8, the atomizing sheet 12, the second motor 14 and the fan 23 to a mobile power source, add an appropriate amount of water into the interior of the straight cylinder 1 through the check valve 13, hold the straight rod 3 and shuttle through the corn stalk group. The operation of the first motor 8 drives the gear 9 to rotate, causing the toothed ring 6 meshing with the gear 9 to rotate, thereby driving the piston rod 5 to reciprocate up and down inside the piston cylinder 4. While driving the top cylinder 2 and the straight cylinder 1 to vibrate up and down, the external air flows to the lower part of the straight cylinder 1 through the dust collecting net 32, the pollen box 19, the through pipe 25, the first one-way valve 20, the piston cylinder 4, the square cylinder 21, the second one-way valve 22 and the fan 23. The air inside the pollen box 19 moves along with the air flow to the corn stalks and corn ears below the straight cylinder 1, increasing the amount of corn pollen, thus enhancing the pollination effect. The operation of the second motor 14 drives the eccentric wheel 15 to rotate, causing the two ends of the straight cylinder 1 to move left and right inside the top cylinder 2, making the corn stalks or corn ears in contact with the straight cylinder 1 vibrate left and right. The setting of the abutting block 10 increases the vibration effect of the left and right movement. The device increases the vibration effect on the corn ears by driving the horizontal and vertical movement of the straight cylinder 1. The operation of the atomizing sheet 12 atomizes the water inside the straight cylinder 1 into small particle water mist, which settles downward to the lower part of the straight cylinder 1, better settling the pollen particles onto the filaments, thereby enhancing the pollination effect of the device on corn.
