Description

Pollen spraying device Technical Field

[0001] This utility model relates to the field of tobacco breeding technology, and in particular to a pollen spraying device. Background Technology

[0002] Hybridization is one of the important methods in traditional tobacco breeding. It involves using the pollen of the male parent to coat the stigma of the female parent to achieve gene recombination between the male and female parents and obtain hybrid offspring. The pollination methods are generally divided into two types: spraying and coating.

[0003] Some existing pollen spraying devices typically use tools such as brushes or cotton swabs to gently apply pollen to the stigma of the stamen. During the contact between the brush or cotton swab and the stigma, the stigma may be damaged, affecting the pollination effect. Alternatively, pollen water is filled into a sprayer and sprayed in large quantities onto the tobacco plants, causing a large amount of pollen to fall onto the tobacco plants or the ground outside, resulting in a significant waste of pollen. Summary of the Invention

[0004] In view of this, to solve the problems of pollen waste in traditional breeding techniques, this utility model provides a pollen spraying device, comprising: a shell, with a receiving space formed inside the shell for storing pollen; a pollen supply channel communicating with the receiving space to allow pollen to flow into the pollen supply channel; a sliding channel communicating with the pollen supply channel and extending perpendicularly to the pollen supply channel; and a spraying channel communicating with the sliding channel and extending perpendicularly to the sliding channel to the outside of the shell; a conveying mechanism configured to transport pollen from the pollen supply channel to the spraying channel by sliding in the sliding channel; and an air injection mechanism configured to spray air toward the pollen transported to the spraying channel to spray pollen from the spraying channel to the outside of the shell.

[0005] According to some embodiments of the present invention, the conveying mechanism includes: a conveying block slidably disposed in a sliding channel, a powder spraying hole formed on the conveying block, the powder spraying hole being in a loaded state communicating with a powder supply channel and an unloaded state communicating with a powder spraying channel as the conveying block moves; and a driving mechanism configured to drive the conveying block to move in the sliding channel.

[0006] According to some embodiments of the present invention, a sliding groove is formed inside the housing, communicating with the sliding channel and having an opening on the side of the housing, and a sealing cap is provided at the opening of the sliding groove.

[0007] According to some embodiments of the present invention, the driving mechanism includes: a push rod extending from the conveyor block through a groove to the outside of the sealing cover; a piston plate mounted on the push rod, forming an air chamber between the piston plate and the sealing cover; and a spring disposed on the push rod, wherein the push rod, under the action of an external force, pushes the conveyor block toward the powder supply channel against the elastic force of the spring.

[0008] According to some embodiments of the present invention, the first end of the gas injection mechanism is located at the top of the powder spraying channel near the outlet of the sliding channel, and the second end is located at the end of the chute away from the sliding channel.

[0009] According to some embodiments of the present invention, the gas injection mechanism is provided with a pressure limiting valve, which is configured to: close when the powder spraying hole moves out of the powder spraying channel, thereby increasing the pressure in the gas chamber to a predetermined pressure; and open when the powder spraying hole moves into the powder spraying channel, so as to spray the pollen in the powder spraying hole through the powder spraying channel.

[0010] According to some embodiments of the present invention, the sealing cover is provided with a one-way valve, which is configured to allow external gas to enter the gas chamber when the piston plate moves away from the sealing cover, and to prevent gas from escaping from the gas chamber when the piston plate moves towards the sealing cover.

[0011] According to some embodiments of this utility model, the bottom of the receiving space is inverted conical to allow pollen to flow into the pollen supply channel.

[0012] According to some embodiments of the present invention, the housing also includes a cap threaded onto the top, and a sieve plate is provided at the center of the cap, with a plurality of through holes formed on the sieve plate.

[0013] According to some embodiments of this utility model, the housing in the accommodating space is handheld.

[0014] Based on the above technical solution, this utility model has at least one or a part of the following technical effects:

[0015] (1) The air injection mechanism can control the quantitative discharge of pollen, so that the pollen can spread in a small area, and thus almost all the pollen falls near the tobacco stamen, so that more pollen can fully contact the stigma and reduce the waste of pollen when spraying.

[0016] (2) When the pollen spraying device is used, it will not come into contact with the stigma, thus avoiding damage to the stigma. Attached Figure Description

[0034] It should also be noted that the directional terms mentioned in the embodiments, such as "up," "down," "front," "back," "left," and "right," are only for reference in the accompanying drawings and are not intended to limit the scope of protection of this utility model. Throughout the drawings, the same elements are represented by the same or similar reference numerals. Conventional structures or constructions will be omitted where they may cause confusion in understanding this utility model.

[0035] Some embodiments of this utility model provide a pollen spraying device, as shown in Figures 1-4, comprising: a housing 1, wherein a receiving space 11 is formed within the housing 1 for storing pollen (not shown in the figures); a pollen supply channel 12 communicating with the receiving space 11 to allow pollen to flow into the pollen supply channel 12; a sliding channel 13 communicating with the pollen supply channel 12 and extending perpendicularly to the pollen supply channel 12; and a spraying channel 14 communicating with the sliding channel 13 and extending perpendicularly to the sliding channel 13 to the outside of the housing 1; a conveying mechanism 2 configured to convey pollen from the pollen supply channel 12 to the spraying channel 14 by sliding within the sliding channel 13; and an air injection mechanism 3 configured to spray air toward the pollen conveyed to the spraying channel 14 to spray pollen from the spraying channel 14 to the outside of the housing 1.

[0036] According to some embodiments of the present invention, the conveying mechanism 2 includes: a conveying block 21 slidably disposed in a sliding channel 13, a powder spraying hole 22 formed on the conveying block 21, the powder spraying hole 22 moving with the conveying block 21 including a loading state communicating with a powder supply channel 12 and an unloading state communicating with a powder spraying channel 14; and a driving mechanism 23 configured to drive the conveying block 21 to move within the sliding channel 13.

[0037] Specifically, according to some embodiments of this utility model, pollen flows from the receiving space 11 into the pollen supply channel 12. The driving mechanism 23 drives the conveying block 21 to connect the pollen spraying hole 22 on the conveying block 21 with the pollen supply channel 12, so that the pollen in the pollen supply channel 12 falls into the pollen spraying hole 22. When the pollen spraying hole 22 is in the loading state, the driving mechanism 23 drives the conveying block 21 to connect the pollen spraying hole 22 with the pollen spraying channel 14. At this time, the pollen spraying hole 22 is in the unloading state, and the pollen is transported to the pollen spraying channel 14. At this time, the air injection mechanism 3 sprays air towards the pollen spraying channel 14 so that the pollen is sprayed from the pollen spraying channel 14 to the outside of the housing 1. Since the air flow rate sprayed from the pollen spraying channel 14 is small, the pollen will not diffuse excessively outward, so that almost all the pollen falls onto the stamen, so that more pollen can fully contact the stigma, greatly reducing the waste during pollen spraying. Moreover, during the pollen spraying operation, the device will not contact the stigma, avoiding damage to the stigma.

[0038] Furthermore, the conveyor block 21 slides within the sliding channel 13. When the powder spraying hole 22 moves below the powder supply channel 12, some pollen in the receiving space 11 slides down the powder supply channel 12 into the powder spraying hole 22 until the powder spraying hole 22 is filled with pollen, automatically completing the filling of the powder spraying hole 22. When the powder spraying hole 22 moves out of the powder supply channel 12, due to the misalignment between the powder spraying hole 22 and the powder supply channel 12, the conveyor block 21 can directly block the powder supply channel 12, resulting in a high degree of automation. Preferably, a soft ring is installed at the bottom opening of the powder supply channel 12 to enhance the sealing effect of the conveyor block 21 on the bottom opening of the powder supply channel 12.

[0039] According to some embodiments of the present invention, as shown in FIG4, a groove 15 is formed inside the housing 1, which communicates with the sliding channel 13 and has an opening on the side of the housing 1. A sealing cover (not shown in the figure) is provided at the opening of the groove 15.

[0040] According to some embodiments of the present invention, as shown in Figures 4 and 5, the drive mechanism 23 includes: a push rod 232 extending from the conveyor block 21 through the slide groove 15 to the outside of the sealing cover; a piston plate 231 mounted on the push rod 232, forming an air chamber (not shown in the figures) between the piston plate 231 and the sealing cover; and a spring 233 disposed on the push rod 232, which pushes the conveyor block 21 toward the powder supply channel 12 under the action of an external force, against the elastic force of the spring 233.

[0041] According to some embodiments of the present invention, the first end of the air injection mechanism 3 is located at the top of the powder spraying channel 14 near the outlet of the sliding channel 13, and the second end is located at the end of the chute 15 away from the sliding channel 13.

[0042] According to some embodiments of the present invention, as shown in FIG4, the gas injection mechanism 3 is provided with a pressure limiting valve 31. The pressure limiting valve 31 is configured to close when the powder spraying hole 22 moves out of the powder spraying channel 14, so that the air chamber is pressurized to a predetermined pressure; and to open when the powder spraying hole 22 moves into the powder spraying channel 14, so that the pollen in the powder spraying hole 22 is sprayed out through the powder spraying channel 14.

[0043] According to some embodiments of the present invention, a one-way valve 32 is provided on the sealing cover, which is configured to allow external gas to enter the gas chamber when the piston plate 231 moves away from the sealing cover, and to prevent gas from escaping from the gas chamber when the piston plate 231 moves towards the sealing cover.

[0044] Specifically, when the push rod 232, under the action of external force, pushes the transmission block 21 towards the powder supply channel 12 against the elastic force of the spring, the powder spraying hole 22 moves into the powder supply channel 12. In other words, the powder spraying hole 22 moves out of the powder spraying channel 14. At this time, the piston plate 231 moves away from the sealing cover, and external gas enters the gas chamber through the one-way valve 32. The pressure limiting valve 31 closes, completing the gas injection. When the pollen in the powder spraying hole 22 is filled, the external force applied to the push rod 232 stops. At this time, the spring returns to its original position, and the piston plate 231 and the transmission block 21 move in opposite directions. Since the pressure limiting valve 31 is in the closed state, the pressure in the gas chamber increases, forming a continuously rising high-pressure chamber. At this time, due to the one-way valve 32, the gas in the gas chamber cannot be discharged to the outside, thus allowing the gas in the gas chamber to enter the gas injection mechanism 3. When there is a sufficient pressure difference across the pressure limiting valve 31, the transmission block 21 moves exactly to the bottom of the gas injection mechanism 3, completing the sealing of the gas injection mechanism 3. When the powder spraying orifice 22 moves into the powder spraying channel 14, the pressure relief valve 31 opens, allowing the gas in the gas injection mechanism 3 to be ejected from the powder spraying orifice 22 and the powder spraying channel 14 through the pressure relief valve 31, thereby spraying pollen. The return of the spring 233 drives the movement of the transmission block 21 and the piston plate 233, simplifying operation and facilitating the use of the device. By setting the one-way valve 32 and the pressure relief valve 31, the gas injection operation is automatically completed during the movement of the transmission block 21 and the piston plate 231, resulting in a high degree of automation in the device.

[0045] According to some embodiments of the present invention, the bottom of the receiving space 11 is inverted conical to allow pollen to flow into the pollen supply channel 12.

[0046] According to some embodiments of this utility model, the housing 1 further includes a cap 16 threaded onto the top, with a sieve plate 161 at the center of the cap 16, and several through holes formed on the sieve plate 161. When adding pollen, the cap 16 is unscrewed from the top of the housing 1, releasing the closed state of the top opening of the receiving space 11. At this time, pollen can be directly poured into the receiving space 11 through the top opening, completing the pollen filling operation. The pollen feeding operation is simple. As the pollen enters the pollen supply channel 12, some external gas can enter the receiving space 11 through the through holes on the sieve plate 161, preventing the formation of a weak negative pressure cavity in the receiving space 11 from affecting the sliding out of the pollen.

[0047] According to some embodiments of the present invention, the housing at the accommodating space 11 is handheld so that the operator can operate it by holding the device.

[0048] The working principle of this utility model is as follows:

[0049] The operator holds the housing 1 and twists the cap 16 in the opposite direction to unscrew the cap 16 from the top of the housing 1, thereby releasing the closed state of the top opening of the containing space 11. At this time, pollen can be poured into the containing space 11 from the top opening, and the pollen filling operation in the device is completed.

[0050] Holding the housing 1, move the device to the top of the tobacco plant's flower stamen and press the pressing end of the push rod 232 to push the transmission block 21 against the elastic force of the spring 233, causing it to move in the sliding channel 13 and simultaneously push the piston plate 231 until the powder injection hole 22 moves into the powder supply channel 12. During this process, a negative pressure chamber is formed in the air chamber in the slide groove 15, allowing external gas to pass through the one-way valve 32 and enter the air chamber to complete the gas injection.

[0051] When the powder spraying hole 22 moves into the powder supply channel 12, the pollen in the receiving space 11 flows into the powder spraying hole 22 through the powder supply channel 12 until the powder spraying hole 22 is filled with pollen, completing the filling of the powder spraying hole 22 with pollen. Then, the pressure on the push rod 232 is released. Due to the reset of the spring 233, the piston plate 231 and the conveying block 21 move in opposite directions. During this process, the conveying block 21 fits against the bottom opening of the air injection mechanism 3 to seal it. And due to the misalignment between the powder spraying hole 22 and the bottom opening of the powder supply channel 12, the bottom opening of the powder supply channel 12 can be directly sealed by the conveying block 21 at the same time.

[0052] During the resetting and sliding process of piston plate 231, the gas in the compressible chamber is compressed so that the gas injection mechanism 3 and the gas chamber form a high-pressure chamber with continuously increasing pressure. Due to the obstruction of pressure relief valve 31, the gas will not be discharged from the first end of gas injection mechanism 3.

[0053] When the powder spraying hole 22 moves into the powder spraying channel 14, the pressure relief valve 31 opens, and the gas in the gas injection mechanism 3 is sprayed out towards the powder spraying hole 22 through the pressure relief valve 31, and then sprayed out from the powder spraying channel 14. Due to the diffusion of a small amount of gas discharged from the bottom opening of the powder spraying channel 14, the pollen is slightly diffused on the tobacco stamen, so that almost all the pollen falls on the tobacco stamen, so that more pollen can fully contact the stigma.

[0054] The embodiments of the present invention have been described above. However, these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Although various embodiments have been described above, this does not mean that the measures in the various embodiments cannot be used advantageously in combination. The scope of the present invention is defined by the appended claims and their equivalents. Various substitutions and modifications can be made by those skilled in the art without departing from the scope of the present invention, and all such substitutions and modifications should fall within the scope of the present invention.
