Description

Technical Field

[0001] This invention relates to the field of agricultural pollination equipment technology, specifically to a device and method for collecting and pollinating the pollen of gourd. Background Technology

[0002] The hanging gourd, belonging to the Cucurbitaceae family, has a significant impact on its fruit set rate and fruit quality due to pollination methods. Traditional manual pollination methods, such as manually collecting pollen with a brush and applying it by smearing, are not only inefficient and labor-intensive but also prone to pollen loss during collection, transportation, and pollination. Furthermore, because the opening time of the male and female flowers of the hanging gourd is short and the pollen viability is limited, manual operations cannot ensure both continuity and timeliness of pollination, severely restricting the improvement of pollination efficiency and pollen utilization.

[0003] According to the research in "Pollination in Cucurbit Crops" (Bomfim, IGA et al., Handbook of Cucurbits, 2016), "Artificial pollination is still the main pollination method for cucurbit economic crops. The pollen activity and stigma receptivity of cucurbit crops have a very short synchronization window, which usually only lasts for a few hours after flowering." It also points out that "the main limitation of artificial pollination is that it is too labor-intensive and time-consuming. Delayed operation can easily lead to pollination occurring outside the optimal window, resulting in fruit set failure or fruit deformity."

[0004] Therefore, the fundamental flaw in existing pollen collection and pollination devices lies in the separation of pollen collection and pollination processes, resulting in an excessively long operational chain and making it difficult to complete high-intensity continuous operations within the limited pollen activity window. This leads to the dual problems of low pollination efficiency and missed optimal pollination opportunities affecting fruit set. Therefore, it is necessary to propose a device and method for collecting and pollinating *Gnaphalium affine* pollen. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an apparatus and method for collecting and pollinating gourd pollen. The apparatus uses a dual-head drive unit to separately drive a collection component and an airflow circulation component, causing a brush head to agitate the flower and dislodge the pollen, which then enters a flow tube under the guidance of a flow guide. Simultaneously, the airflow circulation component provides airflow assistance for the pollen collection process and provides airflow power for pollination, enabling continuous operation of pollen collection, storage, and pollination. This reduces pollen loss during manual pollination and improves pollination efficiency and pollen utilization.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A device for collecting and pollinating gourd pollen includes a controller and a handheld rod. A double-headed drive is fixedly connected to the top of the handheld rod. The double-headed drive is electrically connected to the controller. A collection component for collecting pollen is provided on one side of the double-headed drive. The collection component includes a flow tube. A flow guide is fixedly connected to the opening of the flow tube. A rotating shaft is coaxially fixedly connected to the output end of the double-headed drive near the flow tube. Several support columns are fixedly connected to the side wall of the double-headed drive near the rotating shaft. The other ends of the support columns are fixedly connected to the side wall of the flow tube. A brush head is fixedly connected to the end of the rotating shaft away from the double-headed drive through the side wall of the flow tube to the opening of the flow tube. A storage component for storing pollen is provided at the bottom of the flow tube. An airflow circulation component for pollination and assisting in pollen collection is provided at the other output end of the double-headed drive.

[0007] The technical principles of the above solution are as follows:

[0008] Staff members hold the handle and aim the guide hood at the flower, ensuring the brush head contacts the stamen. The flow tube is tilted upwards, and a controller activates the dual-head drive unit. One output drives a rotating shaft, which in turn rotates the brush head and agitates the flower bud, causing pollen to fall off. The fallen pollen, guided by gravity and the guide hood, enters the flow tube and falls into a storage component at the bottom. Simultaneously, the other output of the dual-head drive unit activates an airflow circulation component, which provides airflow assistance to the collection component, making it easier for pollen to enter the flow tube for collection. During pollination, the airflow circulation component generates airflow, carrying the pollen from the storage component through the flow tube and guide hood to the target flower for pollination.

[0009] The above approach has the following beneficial effects:

[0010] 1. By setting up a collection component and an airflow circulation component, the present invention enables pollen collection and pollination to be completed on the same device, making the operation centralized and portable, reducing the steps of frequently changing tools and going back and forth to pick up and put down, and improving work efficiency.

[0011] 2. The present invention improves collection efficiency and reduces pollen loss by setting a flow guide hood at the inlet of the flow tube and setting a brush head driven by a rotating shaft at the inlet of the flow tube. The brush head moves to make pollen fall off, and the flow guide hood guides the fallen pollen into the flow tube and falls into the storage component.

[0012] 3. This invention improves pollen utilization and pollination efficiency by setting up an airflow circulation component to assist pollen in entering the flow tube during pollen collection and to provide airflow support for pollen output during pollination.

[0013] Furthermore, the storage component includes a transfer tube that is fixedly connected to the bottom of the flow tube. The cross-sectional circle of the transfer tube is tangent to the side wall of the flow tube near the dual-head drive unit. A filter screen is fixedly connected to the top opening of the transfer tube, and a collection bottle is detachably connected to the bottom of the transfer tube.

[0014] Beneficial effects: The connection between the transfer tube and the collection bottle allows pollen entering the flow tube to fall into the collection bottle for storage. When passing through the transfer tube, the filter screen filters out impurities such as petals that fall off during the process of removing pollen from the flower buds. The collection bottle is detachable, making it easy to remove, replace and carry quickly, reducing secondary pollen loss during manual pollen collection.

[0015] Furthermore, the airflow circulation assembly includes a dual-head drive unit with a rotating rod fixedly connected to the output end of one end away from the rotating shaft, a transmission rod rotatably connected to the other end of the rotating rod, a slider rotatably connected to the other end of the transmission rod, a fixed seat fixedly connected to the side wall of the hand handle, a sliding groove opened on the side wall of the fixed seat, the slider slidingly engaging with the sliding groove, a piston rod fixedly connected to the side wall of the slider, a piston cylinder fixedly connected to the bottom of the fixed seat, and a piston plate fixedly connected to the piston plate at the end of the piston rod away from the slider, passing through the top of the piston cylinder and into the piston cylinder.

[0016] A second air intake port is opened on the side wall of the flow tube, and a filter screen is fixedly connected to the second air intake port. A second air inlet is opened at the bottom of the piston cylinder, and the second air intake port is fixedly connected to the second air inlet. A second air inlet one-way solenoid valve is fixedly connected to the second air inlet. The gas flow direction is from the outside of the piston cylinder to the inside of the piston cylinder. A second air outlet is opened at the bottom of the piston cylinder, and a second air outlet is fixedly connected to the second air outlet one-way solenoid valve. The gas flow direction is from the inside of the piston cylinder to the outside of the piston cylinder. Both the second air inlet one-way solenoid valve and the second air outlet one-way solenoid valve are electrically connected to the controller.

[0017] The bottom of the collection bottle has a first air intake port, the top of the piston cylinder has a first air inlet and a first air outlet, and the side wall of the flow tube has a blow hole. The first air intake port and the first air inlet are detachably connected, while the first air outlet and the blow hole are fixedly connected. A first air intake solenoid valve is fixedly connected inside the first air intake port, and the gas flows from inside the collection bottle to outside the collection bottle. A first exhaust one-way solenoid valve is fixedly connected inside the first air outlet, and the gas flows from inside the piston cylinder to outside the piston cylinder. Both the first air intake solenoid valve and the first exhaust one-way solenoid valve are electrically connected to the controller.

[0018] Beneficial effects: The piston plate reciprocates through the cooperation of the rotating rod, transmission rod, slider, and piston plate to generate intake and exhaust. Under the control of the controller, the second intake solenoid valve, the second exhaust solenoid valve, the first intake solenoid valve, and the first exhaust solenoid valve switch the air path. During collection, the second intake port creates negative pressure in the flow tube to assist pollen in entering the flow tube. During pollination, the first intake port carries the pollen in the collection bottle out through the blowing hole with the airflow. At the same time, the filter screen can block the pollen, reducing the loss caused by pollen entering the air path.

[0019] Furthermore, an acceleration gearbox is provided at the output end of the dual-head drive unit near the rotating rod. The output end of the dual-head drive unit is fixedly connected to the input shaft of the acceleration gearbox, and the output shaft of the acceleration gearbox is fixedly connected to the rotating rod.

[0020] Beneficial effects: The speed-up gearbox increases the rotational speed of the rotating rod, thereby increasing the reciprocating frequency of the piston plate and increasing the airflow, making the negative pressure effect more obvious during collection and the airflow power more sufficient during pollination, further improving the efficiency of pollen collection and pollination.

[0021] Furthermore, the end of the flow guide shroud away from the flow tube is detachably connected to a cover.

[0022] Beneficial effects: The detachable design of the cover allows it to work with the flow guide to shield and hold the flowers when collecting pollen, reducing pollen splashing and waste and increasing the probability of pollen entering the flow tube. Removing it during pollination reduces obstruction to the output airflow carrying pollen and makes it easy to clean and replace.

[0023] Furthermore, a battery box is fixedly connected to the bottom of the handheld stick.

[0024] Beneficial effects: The battery box can hold batteries to provide independent power to the device, allowing it to be used without an external power source, thus improving portability and applicability in field operations.

[0025] Furthermore, a housing is fixedly connected to the side wall of the handheld handle.

[0026] Beneficial effects: The housing provides shielding and protection for the airflow circulation and storage components, reducing the impact of external collisions and dust on the operation of the device, and improving structural reliability and safety of use.

[0027] Furthermore, a method for collecting and pollinating *Gnaphalium affine* pollen includes the following steps:

[0028] Step 1, device preparation: Connect the collection bottle detachably to the adapter pipe to connect the collection bottle to the flow pipe, and turn on the controller to put the dual-head drive unit into working condition.

[0029] Step 2, pollen collection: The controller opens the second intake one-way solenoid valve and the second exhaust one-way solenoid valve, while keeping the first intake solenoid valve and the first exhaust one-way solenoid valve closed. The flow tube is raised at an angle, so that the guide shroud is aligned with the male flower stamen of the gourd and the shroud is positioned below the flower to scoop it up. The dual-head drive is activated to rotate the brush head and move the male flower stamen to dislodge the pollen. At the same time, the dual-head drive drives the piston plate to move back and forth, creating a negative pressure in the flow tube through the second air intake. The dislodged pollen enters the flow tube under the action of gravity, the guiding action of the guide shroud, and the negative pressure and slides into the collection bottle.

[0030] Step 3, pollination: The controller opens the first intake solenoid valve and the first exhaust one-way solenoid valve, and closes the second intake one-way solenoid valve and the second exhaust one-way solenoid valve. The guide shroud is aligned with the pistil of the female flower of the gourd. The double-headed drive unit is activated to drive the piston plate to move back and forth, so that the pollen in the collection bottle is drawn in through the first intake port and discharged from the flow tube through the blowing hole. The pollen is sprayed out by the airflow through the guide shroud and attaches to the pistil of the female flower to complete the pollination.

[0031] Beneficial effects: By controlling the opening and closing of the second intake one-way solenoid valve, the second exhaust one-way solenoid valve, the first intake solenoid valve, and the first exhaust one-way solenoid valve, and coordinating with the dual-head drive to drive the brush head to rotate and the piston plate to reciprocate, pollen collection and pollination can be completed continuously according to the working conditions. The operation steps are clear, pollen loss during manual pollen collection and pollination is reduced, and pollination efficiency and pollen utilization rate are improved.

[0032] Furthermore, in step two, after pollen collection is completed, the collection bottle can be removed from the transfer tube to store or pre-treat the pollen inside the collection bottle. After pre-treatment, the collection bottle is reattached to the transfer tube and step three is performed for pollination.

[0033] Beneficial effects: The collection bottle can be disassembled after collection to store or pre-treat pollen, and can be reassembled for pollination when needed, making pollen processing and operation more flexible and facilitating segmented operations.

[0034] Furthermore, in step three, the cover can be removed from the flow guide before pollination.

[0035] Beneficial effects: Removing the cover before pollination can prevent the cover from obstructing the airflow, allowing pollen to be sprayed out more smoothly through the airflow guide and adhere to the female flower stamen, thereby improving the pollination effect.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] The following detailed description illustrates the specific implementation method:

[0047] Example 1:

[0048] As attached Figure 1 and Figure 4As shown: A device for collecting and pollinating gourd pollen, including a controller and a handheld rod 26; a double-headed drive 9 is bolted to the top of the handheld rod 26, and the double-headed drive 9 is electrically connected to the controller.

[0049] The dual-head drive unit 9 has a collection component on one side for collecting pollen. The collection component includes a flow tube 1, and the opening of the flow tube 1 is integrally formed with a flow guide shroud 2.

[0050] The output end of the dual-head drive unit 9, near the flow tube 1, is coaxially bolted to a rotating shaft 4. Several support columns 8 are bolted to the side wall of the dual-head drive unit 9 near the rotating shaft 4, and the other ends of the support columns 8 are bolted to the side wall of the flow tube 1. The end of the rotating shaft 4 away from the dual-head drive unit 9 extends through the side wall of the flow tube 1 to the opening of the flow tube 1 and is bolted to a brush head 5. In this embodiment, the dual-head drive unit 9 is a dual-head motor.

[0051] Specifically, the staff holds the handle 26 and aligns the guide shroud 2 with the gourd flower, so that the brush head 5 contacts the stamen and the flow tube 1 is tilted upward; the controller controls the double-head drive 9 to open, so that the output end of the double-head drive 9 drives the rotating shaft 4 to rotate, the rotating shaft 4 drives the brush head 5 to rotate and pluck the stamen, so that the pollen is detached. The detached pollen enters the flow tube 1 under the action of gravity and the guiding action of the guide shroud 2, thus completing the collection and introduction of pollen.

[0052] like Figure 1 As shown, the bottom of the flow tube 1 is provided with a storage component for storing pollen. The storage component includes a transfer tube 6 that is fixedly connected to the bottom of the flow tube 1. The cross-sectional circle of the transfer tube 6 is tangent to the side wall of the flow tube 1 near the double-headed drive component 9. A filter screen is fixedly connected to the top opening of the transfer tube 6. A collection bottle 7 is detachably connected to the bottom of the transfer tube 6.

[0053] Specifically, the transfer tube 6 is fixedly connected to the flow tube 1, allowing pollen entering the flow tube 1 to slide down the flow tube 1 and enter the collection bottle 7 through the transfer tube 6 for storage. When passing through the transfer tube 6, the filter screen filters out impurities such as petals that fall off during the brush head 5's stirring of the flower buds. Furthermore, the collection bottle 7 is detachably connected to the transfer tube 6, making it convenient for staff to disassemble the collection bottle 7 for storage, transportation, or processing after pollen collection is completed.

[0054] like Figure 2 and Figure 4As shown, the other output end of the dual-head drive 9 is equipped with an airflow circulation assembly for pollination and auxiliary pollen collection. The airflow circulation assembly includes a rotating rod 14 bolted to the output end of the dual-head drive 9 away from the rotating shaft 4, a transmission rod 15 rotatably engaged at the other end of the rotating rod 14, and a slider 13 rotatably engaged at the other end of the transmission rod 15; a fixed seat 11 is bolted to the side wall of the handheld handle 26, a sliding groove 12 is opened on the side wall of the fixed seat 11, the slider 13 is slidably engaged with the sliding groove 12, a piston rod 16 is bolted to the side wall of the slider 13, a piston cylinder 17 is bolted to the bottom of the fixed seat 11, and a piston plate 18 is bolted to the end of the piston rod 16 away from the slider 13 through the top of the piston cylinder 17 and into the piston cylinder 17.

[0055] Specifically, when the output end of the dual-head drive 9 rotates away from the rotating shaft 4, it drives the rotating rod 14 to rotate. The rotating rod 14 drives the slider 13 to slide back and forth in the slide groove 12 through the transmission rod 15. The slider 13 drives the piston rod 16 to move back and forth, causing the piston plate 18 to move back and forth in the piston cylinder 17, thereby changing the rotation of the output end of the dual-head drive 9 into the reciprocating motion of the piston plate 18.

[0056] like Figure 2 and Figure 3 As shown, a second air intake port 24 is opened on the side wall of the flow pipe 1, and a filter screen is attached to the second air intake port 24. A second air inlet 20 is opened at the bottom of the piston cylinder 17. The second air intake port 24 is fixedly connected to the second air inlet 20. A second air inlet one-way solenoid valve is fixedly connected to the second air inlet 20. The gas flow direction is from the outside of the piston cylinder 17 to the inside of the piston cylinder 17. A second air outlet 22 is opened at the bottom of the piston cylinder 17. A second air outlet 22 is fixedly connected to the second air outlet 22. The gas flow direction is from the inside of the piston cylinder 17 to the outside of the piston cylinder 17. Both the second air inlet one-way solenoid valve and the second air outlet one-way solenoid valve are electrically connected to the controller.

[0057] like Figure 2 and Figure 3 As shown, the bottom of the collection bottle 7 has a first air intake port 23, the top of the piston cylinder 17 has a first air inlet 19 and a first air outlet 21, and the side wall of the flow tube 1 has a blowing hole 25. The first air intake port 23 and the first air inlet 19 are detachably connected, and the first air outlet 21 and the blowing hole 25 are fixedly connected. A first air intake solenoid valve is fixedly connected inside the first air intake port 23, and the gas flows from inside the collection bottle 7 to outside the collection bottle 7. A first exhaust one-way solenoid valve is fixedly connected inside the first air outlet 21, and the gas flows from inside the piston cylinder 17 to outside the piston cylinder 17. Both the first air intake solenoid valve and the first exhaust one-way solenoid valve are electrically connected to the controller.

[0058] Specifically, during the pollen collection process, the controller opens the second intake solenoid valve and the second exhaust solenoid valve, and closes the first intake solenoid valve and the first exhaust solenoid valve. When the piston plate 18 moves back and forth, the piston cylinder 17 draws in and exhausts air through the second intake port 20 and the second exhaust port 22. The reciprocating movement of the piston plate 18 creates a negative pressure at the second intake port 24 in the flow tube 1 to assist pollen in entering the flow tube 1. Furthermore, the filter screen set at the second intake port 24 blocks the pollen. The blocked pollen, under the action of gravity and the vibration generated by the rotation of the double-headed drive component 9 and the operation of the airflow circulation component, falls into the collection bottle 7 along the transfer pipe 6, which reduces the loss of pollen entering the airflow circulation component to a certain extent.

[0059] During the pollination process, the controller controls the opening of the first intake solenoid valve and the first exhaust one-way solenoid valve, and closes the second intake one-way solenoid valve and the second exhaust one-way solenoid valve. When the piston plate 18 moves back and forth, the pollen in the collection bottle 7 is sucked into the piston cylinder 17 through the first intake port 23 and output through the first exhaust port 21. The output airflow carries the pollen and enters the flow tube 1 through the blowing port 25 and is sprayed out by the guide hood 2. The staff aligns the guide hood 2 with the pistil of the female flower of the gourd, so that the pollen is sprayed out with the airflow and attaches to the pistil of the female flower to complete the pollination.

[0060] like Figure 2 and Figure 5 As shown, the output end of the dual-head drive unit 9 near the rotating rod 14 is equipped with an acceleration gearbox 10. The output end of the dual-head drive unit 9 is bolted to the input shaft of the acceleration gearbox 10, and the output shaft of the acceleration gearbox 10 is bolted to the rotating rod 14. The end of the flow guide shroud 2 away from the flow pipe 1 is detachably connected to a cover 3. The bottom of the handheld rod 26 is bolted to a battery box 27. The side wall of the handheld rod 26 is bolted to a housing. In this embodiment, the acceleration gearbox 10 is preferably a PLS42 dual-axis planetary gearbox.

[0061] Specifically, the acceleration gearbox 10 essentially achieves transmission speed ratio amplification through planetary gear sets, which is existing technology and will not be elaborated on in this embodiment. In this embodiment, it is used to increase the rotational speed of the rotating rod 14, thereby increasing the reciprocating frequency of the piston plate 18 and increasing the air flow, making the negative pressure assistance effect during pollen collection more obvious and the airflow power during pollination more sufficient.

[0062] The cover 3 and the deflector 2 are detachably connected. When collecting pollen, the cover 3 is located below the flower to reduce pollen splashing. When pollinating, the cover 3 can be removed to reduce obstruction of the airflow.

[0063] The battery box 27 is used to hold the battery and provide power to the controller and dual-head drive unit 9; the housing is used to shield and protect the airflow circulation assembly and storage assembly.

[0064] In this embodiment, the dual-head drive unit 9 drives the brush head 5 to move the stamen and, together with the guide shroud 2, allows the pollen to enter the flow tube 1 and fall into the collection bottle 7 for collection and storage. At the same time, the drive airflow circulation component creates negative pressure to assist in suction during collection and provides airflow to blow out the pollen during pollination, thereby reducing pollen loss and improving pollination efficiency and pollen utilization.

[0065] Example 2:

[0066] As attached Figure 6 As shown, the difference from Example 1 is that a method for collecting and pollinating *Gnaphalium affine* pollen includes the following steps:

[0067] Step 1, device preparation: Connect the collection bottle 7 detachably to the adapter pipe 6 so that the collection bottle 7 is connected to the flow pipe 1, and turn on the controller to put the dual-head drive component 9 into a working state.

[0068] Step 2, pollen collection: The controller opens the second intake one-way solenoid valve and the second exhaust one-way solenoid valve, while keeping the first intake solenoid valve and the first exhaust one-way solenoid valve closed. The flow tube 1 is raised at an angle, so that the guide shroud 2 is aligned with the male flower stamen of the gourd, and the cover 3 is positioned below the flower to hold it. The dual-head drive 9 is activated to rotate the brush head 5 and agitate the male flower stamen to dislodge the pollen. At the same time, the dual-head drive 9 drives the piston plate 18 to move back and forth, creating a negative pressure in the flow tube 1 through the second air intake 24. The dislodged pollen enters the flow tube 1 under the action of gravity, the guiding action of the guide shroud 2, and the negative pressure, and slides into the collection bottle 7. After pollen collection is completed, the collection bottle 7 can be removed from the transfer tube 6 to store or pre-treat the pollen in the collection bottle 7. After pre-treatment, the collection bottle 7 is reinstalled on the transfer tube 6 and step 3 is performed for pollination.

[0069] Step 3, Pollination: The controller opens the first intake solenoid valve and the first exhaust one-way solenoid valve, while closing the second intake one-way solenoid valve and the second exhaust one-way solenoid valve. The guide shroud 2 is aligned with the stamen of the female flower of the gourd. The dual-head drive unit 9 is activated to drive the piston plate 18 to reciprocate, causing pollen in the collection bottle 7 to be drawn in through the first intake port 23 and discharged from the flow tube 1 through the air outlet 25. The pollen is then sprayed out through the guide shroud 2 by the airflow and adheres to the stamen of the female flower, completing pollination. The cover 3 can be removed from the guide shroud 2 before pollination.

[0070] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
