Description

Technical Field

[0001] This utility model relates to the field of plant pollination technology and equipment, and in particular to a high-frequency pulse pollination gun. Background Technology

[0002] Tomato cultivation in my country is mainly divided into two methods: open-field cultivation and greenhouse cultivation. Greenhouse cultivation reduces yield fluctuations caused by climate changes, ensuring stable production throughout the year, and has therefore gradually become the primary method of tomato cultivation. However, greenhouse tomato cultivation requires assisted pollination to guarantee fruit set and yield due to the enclosed space.

[0003] Currently, assisted pollination methods for tomatoes mainly include biological, chemical, and physical approaches. Biological methods involve placing bumblebee hives in greenhouses to promote pollination through bumblebee visits to the flowers. While this method can increase yield and quality, it suffers from problems such as inconsistent activity levels, management difficulties, high hive costs, and a sharp decline in bee populations. Chemical methods involve spraying chemical hormones to stimulate ovary development and fruit formation. Although low-cost and simple to operate, this may lead to deformed fruit, hollow fruit, and food safety issues. Physical methods include three approaches: direct fan blowing, pollinator vibration, and pulsed air blowing. These methods release pollen from the tomato flowers and cause it to adhere to the stigma, thus completing pollination. They offer advantages such as being green and healthy, and having a high fruit set rate, making them suitable for application and promotion.

[0004] However, improper use of electric pollinators can damage tomato flowers and stems, while direct fan blowing results in poor pollen release due to issues such as leaf obstruction and weak airflow vibration. In contrast, pulsed airflow, being intermittent, enhances the vibration effect of tomato flowers, increasing the pollination rate. Furthermore, as a non-contact pollination method, it does not damage the tomato plant and is a more ideal physical pollination method.

[0005] However, traditional pulse airflow equipment is bulky and requires heavy devices such as air pumps and air tanks. When used in greenhouses, it either requires track-driven equipment for pollination or dragging long air pipes, which is very cumbersome and affects the efficiency and cost of manual pollination.

[0014] Preferably, the control component includes a control chip and a frequency adjustment knob thereon, the frequency adjustment knob being connected to control the air volume of the pulse air supply device.

[0015] Preferably, the air supply component is a turbine fan motor located on the rear side inside the gun body. The gun body is a hollow cylindrical structure that matches the external shape of the turbine fan motor, and the rear cover at the end of the gun body corresponds to the air inlet position of the turbine fan motor.

[0016] Preferably, the power bank is connected to the gun handle via a power cord, with both ends of the power cord being quick-releasely connected to the power bank and the lower end of the gun handle, respectively.

[0023] See Figure 1 and Figure 2 A high-frequency pulse pollination gun includes a housing 1 and a pulse air supply device and a control component 5 disposed therein, as well as a mobile power supply 6 for supplying power to the other components; the pulse air supply device includes an air supply component 4, an air filter component 3 and a pulse component 2 disposed in sequence inside the housing 1, the air supply component 4 is disposed on one side of the rear end of the gun, the air filter component 3 is disposed on the air outlet side of the air supply component 4, and the pulse component 2 is disposed on one side of the gun nozzle. The air supply component 4 generates a high-speed airflow towards the muzzle. The air filter component 3 is an air filter plate 31 that divides the high-speed airflow into several airflow streams. The pulse component 2 is a rotating baffle that sequentially blocks each airflow stream of the air filter plate 31. The control component 5 is connected to the mobile power supply 6 and controls the opening and closing of the air supply component 4 and the air volume. The control component 5 controls the pulse air supply device to work. The air supply component 4 of the pulse air supply device generates a high-speed airflow towards the muzzle. Then, the high-speed airflow is divided into several airflow streams by the air filter component 3. Finally, the pulse component 2 sequentially blocks each airflow stream generated by the air filter component 3, causing the airflow streams to be intermittent, thereby forming a pulse airflow. The pulse airflow "strikes" the flower and causes vibration. The tomato flower has a closed structure. The pollen grains on the stamen are released, move, collide, and adhere under the action of the pulse airflow. Some of them successfully enter the pistil, achieving the purpose of pollination.

[0024] like Figure 3 , 4 As shown, the air filter plate 31 is a sealing baffle that fits against the inner wall of the outer casing 1, and has several air outlet holes 32 evenly distributed on it. The pulse component 2 is a rotating wind deflector that automatically rotates after being subjected to wind force and sequentially blocks each air outlet hole 32. The air filter plate 31 is a circular baffle, and the air outlet holes 32 are evenly distributed around the center of the air filter plate 31. The pulse component 2 includes a blade 21, a bearing 24, and a fixing member 23. The fixing member 23 fixes the bearing 24 to the middle of the air filter plate 31, and the blade 21 is rotatably mounted on the bearing 24.

[0025] The blade 21 is sleeved on the outside of the bearing 24 through the collar 22. The blade 21 forms an angle with the plane of the filter plate 31. The fixing member 23 passes through the middle of the bearing 24 and is fixedly set at the center of the filter plate 31.

[0026] A cylindrical support 33 is provided at the center of the air filter plate 31. The support 33 is perpendicular to the surface of the air filter plate 31 and is integrally formed. A screw hole is opened in the middle of the support 33, and the fastener 23 is fixedly installed in the screw hole.

[0027] The number of air outlet holes 32 on the air filter plate 31 is 2-5, and they are evenly distributed in a ring on the air filter plate 31; the number of blades 21 is 1-3, and they are evenly distributed around the collar 22 in the shape of fan blades, and the collar 22 is fixedly sleeved on the outer ring of the bearing 24.

[0028] The outer casing 1 includes a handle 11 and a gun body 12. A pulse air supply device is disposed within the gun body 12, and a control component 5 is disposed within the handle 11. The muzzle of the gun body 12 is provided with a front cover 14 to constrain airflow, and a rear cover 13 is provided at the rear end away from the muzzle. The rear cover 13 is a hemispherical protective cover with perforated structures for ventilation. The air supply component 4 is a turbine fan motor, located at the rear end of the gun body 12, with the turbine fan motor's air outlet facing the muzzle. A switch 51 connects a power supply 6 and the control component 5 to the handle 11. The operator can turn on the machine by pressing and holding the switch 51 to perform pulse air supply and carry out pollination.

[0029] The pulse component 2 and the air filter component 3 are detachably connected to the gun body 12, allowing for easy replacement as needed. The pulse component 2 is mounted on the air filter component 3 via a fastener 23, i.e., a screw. The planar structure of the air filter plate 31 of the air filter component 3 matches the shape of the internal air duct of the gun body 12, allowing it to be snapped into the gun body 12 and secured by a snap-fit ​​device on the inner wall of the gun body 12.

[0030] The pulse component 2 and the air filter component 3 can also be fixed to the gun body 12 by the front cover 14. The inner wall of the gun body 12 is provided with several protrusions to hold the air filter plate 31 against the side of the air supply component 4. The outer wall of the front end of the gun body 12 has external threads, and the inner wall of the rear end of the front cover 14 has matching internal threads. The front cover 14 is connected to the front end of the gun body 12 by threads, and is provided with protrusions to hold the air filter plate 31 against the side of the gun muzzle. The air filter plate 31 is clamped and fixed from front to back.

[0031] Example 1: As Figure 5 , 6 As shown, a single blade 21 mode is adopted, with one blade 21 fixedly connected to the edge of the collar 22. The collar 22 is sleeved on the bearing 24. The bearing 24 is mounted on the bracket 33 of the filter plate 31 by a fastener 23. The bracket 33 is a cylindrical base that is perpendicular to the surface of the filter plate 31 and integrally formed, with a screw hole in the middle. The fastener 23 is a screw that matches the screw hole. The screw fixes the bearing 24 and the blade 21 to the bracket 33. When the air supply component 4 of the pulse air supply device blows out a high-speed airflow, it then passes through the air filter component 3, i.e., the air filter plate 31. The airflow is divided into two streams by the two air outlets 32 on the air filter plate 31. The blade 21 has a certain angle with the airflow, so it rotates under the drive of the airflow. When the blade 21 rotates to the position of one of the air outlets 32, it forms a momentary blockage of the airflow at that air outlet 32. After the blade 21 rotates away, the airflow resumes, thus forming a pulse airflow. When the nozzle of the pollination gun is aimed at the flower, it forms an airflow "impact" on the flower, which causes the flower to vibrate. The pollen on the stamen falls off, and under the action of the wind, some of the pollen "impacts" the stigma of the flower to complete pollination.

[0032] Example 2: Figure 7, 8 As shown, a dual-blade 21 configuration is adopted, with two blades 21 symmetrically fixed at the edge of the collar 22. The collar 22 is fitted onto the bearing 24, and the bearing 24 is mounted on the bracket 33 of the filter plate 31 via a fixing member 23. The bracket 33 is a cylindrical base that is perpendicular to the surface of the filter plate 31 and integrally formed, with a screw hole in the middle. The fixing member 23 is a screw that matches the screw hole, and the screw fixes the bearing 24 and the blades 21 to the bracket 33. When the air supply component 4 of the pulse air supply device blows out a high-speed airflow, it passes through the air filter component 3, i.e., the air filter plate 31. In this embodiment, the air filter plate 31 has three air outlets 32, which divide the airflow into three streams. The blade 21 has a certain angle with the airflow, so it rotates under the drive of the airflow. When one of the blades 21 rotates to the position of a certain air outlet 32, it forms a momentary blockage of the airflow of that air outlet 32 ​​(at this time, the other blade 21 is located between the other two air outlets 32). After the blade 21 rotates away, the airflow resumes, thus forming a pulse airflow. At this time, the other blade 21 has blocked the second air outlet 32, forming a momentary blockage of the airflow, and then another pulse airflow is generated, forming a rapid relay, which generates a continuous airflow "strike" on the flower. When the muzzle of the pollination gun is aimed at the flower, it forms an airflow "impact" on the flower, thereby causing the flower to vibrate, the pollen on the stamen falls off, and under the action of the wind, some of the pollen "impacts" the stigma of the flower to complete pollination.

[0033] Example 3: As Figure 9 , 10 As shown, a three-blade 21 configuration is adopted, with the three blades 21 evenly distributed and fixedly installed at the edge of the collar 22. The collar 22 is fitted onto the bearing 24, and the bearing 24 is installed on the bracket 33 of the filter plate 31 through the fastener 23. The air supply component 4 of the pulse air supply device blows out a high-speed airflow, which then passes through the air filter component 3, i.e., the air filter plate 31. In this embodiment, the air filter plate 31 has four air outlets 32, which divide the airflow into four streams. The blades 21 have a certain angle with the airflow, so they rotate under the drive of the airflow. When one of the blades 21 rotates to the position of a certain air outlet 32, it forms a momentary blockage of the airflow of that air outlet 32 ​​(at this time, the other two blades 21 are located between the other three air outlets 32). After the blades 21 rotate away, the airflow resumes, thus forming a pulse airflow. At this time, the second blade 21 has blocked another air outlet 32, forming a momentary blockage of the airflow, and then another pulse airflow is generated, forming a rapid relay, which generates a continuous airflow "strike" on the flower. When the muzzle of the pollination gun is aimed at the flower, it forms an airflow "impact" on the flower, which causes the flower to vibrate, the pollen on the stamen falls off, and under the action of the wind, some of the pollen "impacts" the stigma of the flower to complete pollination.

[0034] The control component 5 includes a control chip and a frequency adjustment knob 52 mounted on it. The frequency adjustment knob 52 controls the airflow of the pulse air supply device. Operators can rotate the frequency adjustment knob 52 to adjust the airflow according to actual needs, achieving the most suitable pollination airflow. For example, if the plants and flowers in the greenhouse are small and cannot withstand excessive airflow, the frequency adjustment knob 52 can be adjusted to reduce the airflow, thus completing the pollination process.

[0035] The air supply component 4 is a turbine fan motor located inside the gun body 12 on the rear side. The gun body 12 is a hollow cylindrical structure that matches the external shape of the turbine fan motor. The rear cover 13 at the end of the gun body 12 corresponds to the air inlet of the turbine fan motor. The turbine fan motor is a DC brushless high-speed motor with a speed of approximately 100,000-150,000 rpm.

[0036] The portable power supply 6 is connected to the gun handle 11 via a power cord 7, with both ends of the power cord 7 being quick-release connections to the portable power supply 6 and the lower end of the gun handle 11, respectively. During operation, the portable power supply 6 is hung on the operator's waist or in their pocket. This method keeps the pollination gun lightweight, reducing arm fatigue for operators who hold it for extended periods.

[0037] The power bank 6 can also be directly attached to the bottom of the gun handle 11 to form an extended "magazine" structure. This method increases the weight of the power bank 6 when holding the pollination gun, but without the entanglement of the power cord 7, it will not get caught on the plant.

[0038] Select tomato flower spikes with fully open blossoms, apply pulsed airflow to the spike stalk, causing the spike to vibrate and release pollen. The pulsed airflow drives the tomato flower spike to vibrate, thus releasing pollen more efficiently, and a guiding gas flow is used to guide the released pollen to the stigma of the flower to complete pollination.

[0039] This invention provides a non-contact pollination device and method for tomatoes. It utilizes pulsed airflow to vibrate the flower spikes and release pollen. During the pollen's fall after release, airflow guides the pollen to complete the pollination process. This method eliminates the need for direct contact between the tomato flowers and the plant, making it environmentally friendly, non-destructive, and highly efficient. The airflow guidance method achieves more effective pollination after pollen release, increasing fruit set rate. Individual pollination of each tomato flower cluster ensures that the pollen comes from each flower itself, eliminating the need for pre-prepared pollen and achieving precise, efficient pollination while improving fruit set rate. This method solves the problems of contamination or damage and low fruit set rate found in existing tomato pollination methods.

[0040] Comparing the above embodiments with traditional tomato pollination effects, it is evident that the non-contact tomato pollination method provided by this invention, through selecting a fully open tomato flower, aligning the vibration source and airflow source with the flower, inducing pollen release through vibration, and guiding pollination with airflow, can accurately and effectively achieve assisted tomato pollination. This method is green, non-destructive, easy to operate, and highly efficient. Compared to existing methods, it has advantages such as being green and harmless, requiring no pollen preparation, and improving pollination effectiveness, thus possessing broad market prospects.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
