Description

Technical Field

[0001] This utility model relates to the field of pollination tools, and more particularly to auxiliary tools for corn pollination. Background Technology

[0002] Pollination is a crucial stage in the growth and development of corn, significantly impacting its final yield and quality. To improve pollination efficiency and yield, artificial pollination is employed, using auxiliary tools to assist in the pollination process.

[0003] Traditional pollination aids typically involve placing the pollinator close to the corn tassel, gently shaking the flower to collect pollen into a container, and then using a dry brush to apply the collected pollen to the silks. The success rate of this type of pollination aid largely depends on the pollinator's skill and expertise. If the pollinator is not skilled or operates improperly, it may damage the silks, affecting the pollination effect or even causing pollination failure.

[0004] Therefore, in view of the fact that the traditional pollination aids mentioned above may damage the silks and affect the pollination effect, a corn pollination aid can be designed. By designing the tool as an air-jet pollination gun, the airflow will spray pollen onto the silks, avoiding direct contact between the tool and the silks, thus solving the above problems. Utility Model Content

[0005] To overcome the limitations of traditional auxiliary tools, the success rate of pollination largely depends on the operating skills and proficiency of the pollinators. If the pollinators are not skilled or operate improperly, they may damage the filaments, affecting the pollination effect or even causing pollination failure.

[0006] The technical solution of this utility model is as follows: a corn pollination auxiliary tool, including a pollination gun, a powder spray nozzle, a splash guard, an air shaft, and an air plug; the front end of the pollination gun is provided with a powder spray nozzle for pollinating the corn stamens, the outer end of the powder spray nozzle is fitted with a splash guard for preventing the stamens from being sprayed out, the front end of the pollination gun is provided with a powder spraying chamber for spraying pollen into the powder spray nozzle, the rear end of the pollination gun is provided with an air inflation chamber for providing airflow, the air inflation chamber is provided with an air shaft, the front end of the air inflation shaft is provided with an air plug, and the front end of the pollination gun is provided with a pollen tube for supplying pollen.

A fastening groove corresponding to the fastening slide is provided on both sides of the rear end of the pollination gun, and the sealing cover is matched and fastened to the rear end of the pollination gun.

[0009] Preferably, a connecting connector is provided above the front end of the outer end of the pollination gun, and the lower end of the pollen tube extends into the interior of the connecting connector. The pollen tube is connected to the pollen chamber through the connecting connector.

[0010] Preferably, the rear end of the inflation chamber is provided with a through shaft hole, the rear end of the inflation shaft extends through the through shaft hole to the outer end of the pollination gun, a limiting block is provided at the end of the inflation shaft away from the inflation plug, a return spring is sleeved on the outer end of the inflation shaft, one end of the return spring is connected to the inflation plug, the other end of the return spring is connected to the rear end of the inflation chamber, and spring damping is provided inside the return spring.

[0011] Preferably, the pollination gun has a handle at the lower outer end, a guide sleeve at the rear end of the handle, an inflation push rod inside the guide sleeve, and an inflation handle at the rear end of the inflation push rod.

[0013] Preferably, the splash guard includes a funnel-shaped cover, with a mounting sleeve at the rear end of the funnel-shaped cover, a threaded groove on the inner wall of the mounting sleeve, a threaded sleeve with a corresponding threaded groove fitted at the rear end of the outer end of the powder spray nozzle, and a converging cover at the front end of the funnel-shaped cover.

[0014] The beneficial effects of this utility model are as follows: Compared with traditional pollination aids, which may damage the filaments and affect the pollination effect, this application reduces the unevenness and operational errors of manual pollination by mechanized operation, thereby improving pollination efficiency and success rate. It avoids the problems of filament damage and pollination failure caused by unskilled or improper operation of pollinators. By using airflow to push pollen into the flower bud, the influence of human factors is reduced, significantly improving the success rate of pollination. It does not require direct contact with the filaments, reducing the risk of filament damage caused by improper operation and ensuring pollination quality. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-4 This utility model provides an embodiment of a corn pollination auxiliary tool, including a pollination gun 1, a powder spray nozzle 3, a splash guard 4, an inflation shaft 7, and an inflation plug 17; the front end of the pollination gun 1 is provided with a powder spray nozzle 3 for pollinating corn stamens, the outer end of the powder spray nozzle 3 is fitted with a splash guard 4 for preventing the stamens from being sprayed out, the front end of the pollination gun 1 is provided with a powder spraying chamber 102 for spraying pollen into the powder spray nozzle 3, the rear end of the pollination gun 1 is provided with an inflation chamber 101 for providing airflow, the inflation chamber 101 is provided with an inflation shaft 7, the front end of the inflation shaft 7 is provided with an inflation plug 17, and the front end of the pollination gun 1 is provided with a pollen tube 5 for supplying pollen.

[0022] Please see Figures 1-2 In this embodiment, a sealing cover 6 is provided above the rear end of the pollination gun 1. A fastening slide strip 601 is provided on both sides of the lower end of the sealing cover 6. A fastening groove 19 corresponding to the fastening slide strip 601 is opened on both sides of the rear end of the pollination gun 1. The sealing cover 6 is matched and fastened to the rear end of the pollination gun 1. By combining the fastening slide strip 601 and the fastening groove 19, after pollination, the staff can close or open the sealing cover 6 through the fastening slide strip 601 along the fastening groove 19, so as to facilitate opening the air chamber 101 to clean the inside of the pollination gun 1. A connecting connector 14 is provided above the front end of the outer end of the pollination gun 1. The lower end of the pollen tube 5 extends into the interior of the connecting connector 14. The pollen tube 5 is connected to the pollen flushing chamber 102 through the connecting connector 14. By combining the pollen tube 5 and the connecting connector 14, the staff can put the pre-collected pollen into the pollen tube 5 for collection. During operation, the pollen can enter the pollen flushing chamber 102 along the connecting connector 14.

[0023] Please see Figures 2-3 In this embodiment, a through shaft hole 15 is provided at the rear end of the inflation chamber 101. The rear end of the inflation shaft 7 extends through the through shaft hole 15 to the outer end of the pollination gun 1. A limiting block 16 is provided at the end of the inflation shaft 7 away from the inflation plug 17. A return spring 18 is sleeved on the outer end of the inflation shaft 7. One end of the return spring 18 is connected to the inflation plug 17, and the other end of the return spring 18 is connected to the rear end of the inflation chamber 101. Spring damping is provided inside the return spring 18. A gun handle 2 is provided below the outer end of the pollination gun 1. A guide sleeve 10 is provided at the rear end of the gun handle 2. An inflation push rod 11 is provided inside the guide sleeve 10. An inflation push handle 13 is provided at the rear end of the inflation push rod 11. An inflation slider 12 is provided at the front end of the inflation push rod 11. The bottom of the air chamber 101 is provided with an inflation groove 9 corresponding to the inflation slider 12. The upper end of the inflation slider 12 passes through the inflation groove 9 and is connected to the inflation plug 17. The inflation shaft 7, the return spring 18 and the inflation plug 17 are combined so that when not in operation, the return spring 18 is in the natural state and the inflation plug 17 is located at the front end of the air chamber 101. When inflation is needed, the operator can pull the inflation push handle 13, which slides backward along the inflation groove 9 through the inflation slider 12, thereby driving the inflation plug 17 and the inflation shaft 7 to move backward, causing the return spring 18 to contract under pressure. After contraction, the operator releases the inflation push handle 13, causing the return spring 18 to push the inflation plug 17 to reset, and pushing the airflow into the powder mixing chamber 102.

[0024] Please see Figures 3-4 In this embodiment, the splash shield 4 includes a funnel-shaped shield 403. The rear end of the funnel-shaped shield 403 is provided with an installation sleeve 401. The inner wall of the installation sleeve 401 is provided with a threaded groove 402. The rear end of the outer end of the powder nozzle 3 is fitted with a threaded sleeve 8 corresponding to the threaded groove 402. The front end of the funnel-shaped shield 403 is provided with a gathering shield 404. By combining the funnel-shaped shield 403 and the gathering shield 404, after the worker screws the splash shield 4 onto the threaded sleeve 8 through the threaded groove 402 of the installation sleeve 401, when the pollen is sprayed out, the funnel-shaped structure of the funnel-shaped shield 403 can bring the pollen into contact with the filaments as much as possible, while the gathering structure of the gathering shield 404 can prevent the pollen from spreading outward.

[0025] During the operation, the staff first loads the collected pollen into the pollen tube 5, then holds the handle 2 and aims the splash guard 4 at the corn bud to ensure that the spray nozzle 3 can accurately spray the pollen onto the silks.

[0026] Then, pull the inflation push handle 13 so that it slides backward along the inflation slide groove 9 through the inflation slider 12, thereby driving the inflation plug 17 and the inflation shaft 7 to move backward, causing the return spring 18 to contract under pressure. After the spring is fully contracted, the operator releases the inflation push handle 13 so that the return spring 18 pushes the inflation plug 17 to reset, pushing the airflow into the powder filling chamber 102.

[0027] The air plug 17 is pushed into the air chamber 101, and the airflow is pushed into the pollen chamber 102. The influx of airflow causes pollen to be drawn from the pollen tube 5 into the pollen chamber 102. Then, the airflow enters the flower bud through the pollen nozzle and comes into contact with the filaments. When the pollen is sprayed out, the funnel-shaped structure of the funnel-shaped cover 403 can make the pollen come into contact with the filaments as much as possible, while the constricting structure of the constricting cover 404 can prevent the pollen from spreading outward.

[0028] Through the above steps, this application combines a pollination gun 1, a powder spray nozzle 3, a splash guard 4, an air shaft 7, and an air plug 17. This allows workers to collect pollen in the pollen tube 5 beforehand, hold the pollination gun 1, aim the splash guard 4 at the corn bud, and then push the air shaft 7. The air plug 17 is then pushed into the air chamber 101, propelling the airflow into the powder spraying chamber 102. The influx of airflow draws pollen from the pollen tube 5 into the powder spraying chamber 102, where it is then carried by the airflow through the powder spray nozzle into the bud and contacts the silks. This reduces the unevenness and operational errors associated with manual pollination, and improves pollination efficiency and success rate.
