Description

Technical Field

[0001] This utility model relates to the field of artificial pollination technology, and in particular to a handheld artificial pollinator. Background Technology

[0002] The pollinator uses a controllable airflow to evenly deliver pollen to the silks of the corn ear, achieving efficient and precise artificial pollination. It is suitable for various planting environments such as open fields and greenhouses, and aims to solve the problems of low efficiency, large pollen waste, and high labor intensity of traditional artificial pollination.

[0003] Currently, in the artificial pollination of corn, some existing simple pollination devices still have significant shortcomings in practical applications. These devices are often simply assembled from single-function components, resulting in defects such as loose structure and low degree of system integration. Specifically, the lack of coordinated design between the power, pollen storage and spraying modules leads to a bulky overall structure and poor center of gravity distribution, making operation cumbersome and inconvenient to carry.

[0004] Therefore, it is necessary to develop a lightweight handheld pollinator to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of bulky overall structure and poor center of gravity distribution, which make operation cumbersome and inconvenient to carry.

[0006] The technical solution of this utility model is: a handheld pollinator, comprising an outer shell, a control panel, a ventilation hood, a mounting frame, a fan, a pollen bin, a sieving frame, guide rods, a plastic trigger, a sliding lever, a sliding seat, a first elastic element, a contact block, and a touch switch. A control panel is located on one side of the outer shell, and a ventilation hood is fixedly connected to the rear side of the outer shell. A mounting frame is installed inside the outer shell, and a fan is located within the mounting frame. The outlet of the pollen bin is threadedly connected to the outer shell. Two guide rods are fixedly connected inside the outer shell, and both guide rods share a common... A slidable sieve rack is connected to the pollen bin's outlet. A plastic trigger is also slidably mounted in the middle of the outer casing. A sliding lever is fixedly connected to one side of the plastic trigger. The sliding lever slides within a sliding seat installed inside the outer casing, and a first elastic element connects the sliding lever and the sliding seat. A contact block is fixedly connected to one side of the plastic trigger. A corresponding touch switch is also installed inside the outer casing. The control panel can adjust the fan speed. When the plastic trigger is pulled, the contact block triggers the touch switch, starting the fan.

[0007] Further explanation: It also includes a mounting plate, a motor, a cam, and a second elastic element. The mounting plate is fixedly connected to the outer shell, and a motor is mounted on one side of the mounting plate. A cam is fixedly connected to the output shaft of the motor, and the cam makes rotational contact with the screen frame. The second elastic element is sleeved on the outer side of the guide rod, and the two ends of the second elastic element are connected to the screen frame and the outer shell. The speed of the motor can be adjusted by the control panel. When the contact block triggers the touch switch, the motor starts together with the fan and periodically pushes the screen frame, causing it to vibrate at high frequency along the guide rod under the action of the second elastic element.

[0008] Further explanation: It also includes a nozzle, guide plates, a fixed base, a sliding block, and a third elastic element. Four guide plates are fixedly connected to the rear side of the nozzle. The inner wall of the outer shell is provided with corresponding guide grooves. The guide plates are slidably embedded in the guide grooves, allowing the nozzle to slide back and forth relative to the outer shell. A fixed base is fixedly connected to the top of the outer shell. A sliding block is slidably installed inside the fixed base. The bottom end of the sliding block penetrates the outer shell and contacts the uppermost guide plate at the rear of the nozzle. The contact surface between the sliding block and the guide plate is rounded. The third elastic element is sleeved on the sliding block, and both ends of the third elastic element are connected to the sliding block and the fixed base, respectively. Under the thrust of the third elastic element, the bottom end of the sliding block can be engaged in the slot on the rear side of the uppermost guide plate.

[0009] To further explain, it also includes a protective net, which is installed on the front side of the fan inside the mounting frame.

[0010] To further explain, it also includes a cushioned hand guard; a cushioned hand guard is provided on the back side of the outer casing handle.

[0011] To further explain, it also includes plastic observation panels; multiple plastic observation panels are installed on the pollen bins.

[0012] The beneficial effects of this utility model are as follows: 1. By setting up a linkage control mechanism consisting of a plastic trigger, a contact block and a touch switch, the utility model allows the user to accurately control the start and stop of the fan with a single pull of the trigger. This design, combined with the sieve frame located directly below the pollen bin outlet, enables the airflow to blow the pollen on the sieve frame evenly and controllably. Combined with its overall lightweight and portable design, it significantly improves the flexibility, accuracy and pollen utilization rate of artificial pollination in diverse working environments, and significantly improves the accuracy and pollen utilization rate of pollination operations.

[0013] 2. This utility model achieves continuous mechanical sieving of pollen by adding a cam driven by a motor and cooperating with a second elastic element to make the sieve frame vibrate at high frequency along the guide rod. This vibration process can effectively disperse the pollen falling from the pollen bin and prevent it from clumping or blocking in the air, thereby ensuring smooth and stable pollen output.

[0014] 3. This utility model employs a quick-connect structure consisting of a guide plate, a sliding block, and a third elastic element, enabling one-click assembly and disassembly of the nozzle assembly. Users can easily remove the nozzle by simply pulling the sliding block, and during replacement, they only need to align the guide plate of the new nozzle and push it in; the mechanism will then automatically lock. This design greatly simplifies the nozzle replacement process, allowing the equipment to be flexibly and conveniently equipped with various specialized connectors according to specific operating scenarios and crop types, effectively improving the equipment's versatility and operational efficiency.

Detailed Implementation

[0023] Example: A handheld artificial pollinator, such as Figures 1-3As shown, the device includes an outer casing 1, a control panel 101, a ventilation hood 2, a mounting frame 3, a fan 4, a pollen bin 5, a sieve rack 501, a guide rod 502, a plastic trigger 6, a sliding lever 7, a sliding seat 8, a first elastic element 9, a contact block 10, and a touch switch 11. A cushioned hand guard 21 is provided on the rear side of the handle of the outer casing 1. The control panel 101 is located on the right side of the outer casing 1. The ventilation hood 2 is fixedly connected to the rear side of the outer casing 1. The mounting frame 3 is installed inside the outer casing 1, and the fan 4 is installed inside the mounting frame 3. A protective net 20 is installed in front of the fan 4 inside the mounting frame 3. The discharge port of the pollen bin 5 is threadedly connected to the outer casing 1. Multiple plastic observation plates 22 are provided on the pollen bin 5. The outer casing 1 is fixedly connected to... There are two guide rods 502, and a sieve frame 501 is slidably connected to both guide rods 502. The sieve frame 501 corresponds to the discharge port of the pollen bin 5. A plastic trigger 6 is also slidably installed in the middle of the outer shell 1. A sliding lever 7 is fixedly connected to the rear side of the plastic trigger 6. The sliding lever 7 slides in a sliding seat 8 installed inside the outer shell 1. A first elastic element 9 is also connected between the sliding lever 7 and the sliding seat 8. A contact block 10 is fixedly connected to the middle of the rear side of the plastic trigger 6. A touch switch 11 corresponding to the contact block 10 is also provided inside the outer shell 1. The control panel 101 can adjust the fan speed of the fan 4. When the plastic trigger 6 is pulled, the contact block 10 triggers the touch switch 11, and the fan 4 is started.

[0024] When using this device, the user first presets the fan speed of the fan 4 via the control panel 101. Then, the pollen bin 5, filled with pollen, is screwed onto the interface on the top of the outer casing 1, ensuring a tight and continuous connection. At this time, the pollen in the pollen bin 5 will naturally fall onto the sieving rack 501 located directly below it. The sieving rack 501 buffers and sieving the pollen. When aligned with the target flower, the user pulls the plastic trigger 6. The plastic trigger 6 drives the sliding lever 7 on its rear side to slide within the sliding seat 8, compressing the first elastic element 9. Simultaneously, the contact block 10 fixed to the plastic trigger 6 moves and triggers the actuation mechanism. When switch 11 is triggered, fan 4 inside mounting frame 3 immediately starts, generating airflow. This airflow evenly blows pollen through sieve frame 501, effectively preventing excessive pollen leakage at one time. After releasing plastic trigger 6, sliding lever 7 and contact block 10 return to their original positions under the reset action of first elastic element 9, trigger switch 11 is disconnected, and fan 4 stops working. Through integrated design, the feeding, sieving, and air supply systems are integrated into a compact outer shell 1, making the overall structure lightweight and easy to operate. It is very convenient for users to carry and perform long-term handheld operations, effectively improving the efficiency and convenience of manual pollination.

[0025] like Figures 4-5As shown, it also includes a mounting plate 12, a motor 13, a cam 14, and a second elastic element 15. The mounting plate 12 is fixedly connected to the outer shell 1. The motor 13 is mounted on the front side of the mounting plate 12. The cam 14 is fixedly connected to the output shaft of the motor 13. The cam 14 rotates into contact with the screen frame 501. The second elastic element 15 is sleeved on the outer side of the guide rod 502, and both ends of the second elastic element 15 are connected to the screen frame 501 and the outer shell 1. The speed of the motor 13 can be adjusted by the control panel 101. When the contact block 10 triggers the touch switch 11, the motor 13 starts together with the fan 4 and periodically pushes the screen frame 501, causing it to vibrate at high frequency along the guide rod 502 under the action of the second elastic element 15.

[0026] When the contact block 10 triggers the touch switch 11, the motor 13 on the front side of the mounting plate 12 and the fan 4 start synchronously. The output shaft of the motor 13 drives the cam 14 to start rotating. The rotating cam 14 periodically lifts the sieve frame 501, causing it to overcome the elastic force of the second elastic element 15 and slide upward along the guide rod 502. After the cam 14 protrusion has rotated, the sieve frame 501 returns to its original position under the restoring force of the second elastic element 15. This cycle continues, and the sieve frame 501 vibrates at a high frequency along the guide rod 502 under the drive of the cam 14. This vibration process can continuously and evenly sieve the pollen falling from the pollen bin 5 outlet, prevent clumping, and ensure smooth pollen discharge. The speed of the motor 13 can be adjusted through the control panel 101 to control the vibration frequency of the sieve frame 501.

[0027] like Figure 6 and Figure 7 As shown, it also includes a nozzle 16, a guide plate 1601, a fixed base 17, a sliding block 18, and a third elastic element 19. Four guide plates 1601 are fixedly connected to the rear side of the nozzle 16. The inner wall of the outer shell 1 is provided with corresponding guide grooves. The guide plates 1601 are slidably embedded in the guide grooves, so that the nozzle 16 can slide back and forth relative to the outer shell 1. A fixed base 17 is fixedly connected to the top of the outer shell 1. A sliding block 18 is slidably arranged inside the fixed base 17. The bottom end of the sliding block 18 penetrates the outer shell 1 and contacts the uppermost guide plate 1601 on the rear side of the nozzle 16. The contact surface between the sliding block 18 and the guide plate 1601 is rounded. The third elastic element 19 is sleeved on the sliding block 18, and both ends of the third elastic element 19 are connected to the sliding block 18 and the fixed base 17, respectively. Under the pushing force of the third elastic element 19, the bottom end of the sliding block 18 can be inserted into the slot on the rear side of the uppermost guide plate 1601.

[0028] When it is necessary to replace the nozzle 16 connector with a different model or function, the user pulls the sliding block 18 upwards, causing it to compress the third elastic element 19 and disengage it from the guide plate 1601 on the rear side of the nozzle 16. This allows the entire nozzle 16 assembly to be removed from the housing 1. Subsequently, the guide plates 1601 of other nozzle 16 assemblies are aligned with the guide grooves inside the housing 1 and pushed in until the sliding block 18 automatically resets under the pushing force of the third elastic element 19, with its bottom end locking into the slot or structure on the rear side of the guide plate 1601. This completes the quick installation and locking of the new connector. This design greatly simplifies the nozzle 16 replacement process, allowing the equipment to be flexibly equipped with a variety of special connectors to meet diverse pollination scenario requirements.
