Description

Technical Field

[0001] This utility model relates to the field of papaya cultivation technology, specifically to a papaya pest and disease control device. Background Technology

[0002] Papaya is an important economic crop in subtropical regions. Originally from tropical America, it was introduced to China during the Ming and Qing dynasties and is widely cultivated in tropical cities in southern China. It is now widely grown in tropical and warmer subtropical regions worldwide. Good varieties include Lingnan, Suizhonghong, and Thai Red Flesh, with Lingnan being considered the best in quality.

[0003] Papaya cultivation inevitably suffers from pests, particularly aphids and fruit flies. Current control methods primarily involve trapping and pesticide spraying. While these methods are fast-acting and suitable for large-scale operations, they are labor-intensive, and excessive pesticide spraying can lead to pesticide residues and affect product quality. Trapping, on the other hand, is slower to take effect and has a narrower control range, but it is environmentally friendly and less labor-intensive. Therefore, for specific pests, trapping is a more environmentally friendly, time-saving, and labor-saving method, enabling continuous trapping. For example, patent CN202221904811.0 – a vegetable pest trapping and control device – cleverly combines three trapping methods into one device by placing a bait box containing food or insect pheromones at the top opening of the casing and installing a UV lamp on the bottom of the shielding plate. This significantly improves the trapping efficiency. Furthermore, a ring-shaped electric grid is set around the bait box and UV lamp, which electrocutes or stuns vegetable pests as they approach the bait box or UV lamp, further enhancing the trapping efficiency. However, due to long-term use, the dead insects in the ring-shaped electric grid in this patent tend to stick to it and are continuously heated by the electric grid, which makes these insects stick firmly to the grid. In addition to wasting electricity, it can also easily cause short circuits in the grid.

[0004] Currently, the cleaning of electric grids is primarily done manually on a regular basis to ensure the normal operation of the entire grid. However, when large-scale pest and disease control devices are used in plantations, the workload of cleaning the grid becomes enormous and labor-intensive. To address this, patent CN 220694219U – a forest pest and disease control trap – utilizes a structure including a motor, horizontal bar, vertical bar, fixed bar, and cleaning brush to facilitate cleaning the grid surface and improve its effectiveness. The design also includes a fixed post, movable post, threaded hole, and locking bolt to allow for height adjustment, enhancing practicality. However, the fixed bar and cleaning brush lack adjustability. If the cleaning brush experiences slight wear or bends due to prolonged use, it may fail to adhere properly to the grid's outer wall, reducing cleaning quality and necessitating brush replacement, increasing costs and waste. Furthermore, the design of the fixed bar and cleaning brush only accommodates one type of grid, hindering future replacements and limiting convenience. Utility Model Content

[0005] In order to overcome one of the shortcomings of the existing technology, the purpose of this utility model is to provide a papaya pest and disease control device. This papaya pest and disease control device can achieve self-cleaning of the power grid and has strong applicability.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0007] A papaya pest and disease control device includes an installation frame, an installation platform mounted on the installation frame, and a trapping lamp mounted on the installation platform. The installation platform is located on the outside of the trapping lamp and is equipped with a cylindrical electric grid. A cover is provided above the installation platform. A rotating disk is coaxially mounted on the cover and the electric grid. At least one insulating scraper is provided on the rotating disk. The insulating scraper abuts against the outer wall of the electric grid. The cover is provided with a drive mechanism for driving the rotating disk to rotate. A groove is provided radially on the rotating disk. One end of the insulating scraper is slidably mounted in the groove. An adjusting bolt is screwed onto the outward end face of the groove. One end of the adjusting bolt is rotatably connected to the insulating scraper. The adjusting bolt can adjust the sliding position of the insulating scraper in the groove.

[0008] Furthermore, the driving mechanism includes a drive motor, which is mounted on the cover and connected to a rotating shaft on the rotating disk.

[0009] Furthermore, the driving mechanism includes a drive shaft, which is rotatably mounted on the cover. One end of the drive shaft is provided with a fan blade, and the other end of the drive shaft is connected to the rotating shaft on the rotating disk via a bevel gear.

[0010] Furthermore, the bottom of the installation platform is provided with an installation hole, and an installation base is fitted into the installation hole, with the trapping light installed on the installation base.

[0011] Furthermore, the insulating scraper is provided in two sets and is evenly distributed on the rotating disk.

[0012] Furthermore, the insulating scraper includes a sliding part and a scraping part. The sliding part is slidably installed in the groove. The end of the sliding part corresponding to the adjusting bolt is rotatably connected. An elastic part is provided on the sliding part. One end of the scraping part is installed on the elastic part. The elastic part can force the scraping part to abut against the outer wall of the power grid.

[0013] Furthermore, a brush bristle is provided on one side of the scraping part, and the brush bristle abuts against the outer wall of the power grid.

[0014] Furthermore, a collection trough is provided on the periphery of the power grid on the installation platform.

[0015] Furthermore, a solar panel is provided on the shield, and a battery is provided at the bottom of the installation platform. The battery supplies power to the power grid, and the solar panel is electrically connected to the battery.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model discloses an improved papaya pest control device based on existing trapping devices. Besides retaining the existing electric shock trapping method, it adds a rotating disk and insulating scraper to the electric grid structure. This allows the rotating disk to be driven by a drive mechanism, which in turn forces the insulating scraper to rotate around the outer circumference of the electric grid, scraping away the dead pests and diseases outside the grid. This achieves both protection and cleaning of the electric grid, extending its service life. Furthermore, a cover is installed above the electric grid, which not only protects it from rain or fallen leaves but also provides a mounting base for the rotating disk. The design of the adjusting bolts and sliding grooves allows the insulating scraper to be adjusted from the center of rotation to adapt to electric grids of different diameters and to varying degrees of deformation or wear of the scraper, ensuring that the scraper always remains close to the outer wall of the electric grid for effective cleaning.

[0025] Mounting frame 10, mounting platform 20, collection trough 21, mounting base 22, trapping light 30, electric grid 40, shielding cover 50, solar power panel 51, rotating disk 60, slide 61, adjusting bolt 62, insulating scraper 70, sliding part 71, scraping part 72, elastic part 73, drive mechanism 80, drive motor 81, bevel gear 82, drive shaft 83, fan blade 84. Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0027] Reference Figures 1 to 5 The device for controlling pests and diseases of papaya shown includes a mounting frame 10, a mounting platform 20 mounted on the mounting frame 10, and a trapping lamp 30 mounted on the mounting platform 20. The mounting platform 20 is surrounded by a cylindrical electric grid 40. A cover 50 is provided above the mounting platform 20. A rotating disk 60 is coaxially mounted on the cover 50 and the electric grid 40. At least one insulating scraper 70 is provided on the rotating disk 60, and the insulating scraper 70 abuts against the outer wall of the electric grid 40. A drive mechanism 80 for driving the rotating disk 60 to rotate is provided on the cover 50.

[0028] In this application, the mounting frame 10 can be either a column structure or a clamp structure. Since papaya plants are relatively large, to improve installation efficiency and accommodate pest and disease control on multiple papaya plants, this application adopts a column structure, making it easier for workers to insert the entire control device into the ground. Furthermore, the installation platform 20 is a disc-shaped platform structure, which is detachably designed from the mounting frame 10, for example, through a threaded connection. Of course, in some embodiments, the mounting frame 10 can also have a hook structure, making it convenient for workers to hang it on an external support or on the papaya plant.

[0029] It should be noted that in the above embodiment, the diameter of the cover 50 is larger than the diameter of the mounting platform 20, which facilitates rain protection later. Furthermore, the cover 50 can be mounted on the mounting platform 20 via a column; both are detachable, facilitating the later assembly and disassembly of the trap light 30 and the electric grid 40. The cover 50 is generally funnel-shaped to facilitate drainage. Therefore, in this application, the cover 50 is shaped like an inverted disc.

[0030] This papaya pest and disease control device is an improvement on existing trapping devices. Besides retaining the existing electric shock trapping method, it adds a rotating disc 60 and an insulating scraper 70 to the electric grid 40. This allows the rotating disc 60 to be driven by a drive mechanism 80, which in turn forces the insulating scraper 70 to rotate around the outer perimeter of the electric grid 40 to scrape away dead pests and diseases outside the grid, thus protecting and cleaning the electric grid 40 and extending its service life. Furthermore, a cover 50 is installed above the electric grid 40, which not only protects it from rain or fallen leaves but also provides a mounting base for the rotating disc 60.

[0031] join Figure 4 and Figure 5 In one embodiment of this application, to facilitate the later disassembly and assembly of the trapping lamp 30, the bottom of the mounting platform 20 is provided with mounting holes, and a mounting base 22 is fitted into the mounting holes. The trapping lamp 30 is mounted on the mounting base 22. The mounting base 22 can integrate a lamp holder, battery, power cord, and other structures for easy disassembly. Of course, in some embodiments, the trapping lamp 30 can be replaced with a trapping box containing a trapping agent, thus achieving diversified trapping and increasing the breadth of pest control.

[0032] In one embodiment of this application, in order to better collect insect carcasses, the mounting platform 20 is provided with a collection trough 21 on the periphery of the power grid 40.

[0033] See Figure 5 In one embodiment of this application, in order to reduce energy consumption, a solar power generation panel 51 is provided on the shielding cover 50, and a storage battery is provided at the bottom of the mounting platform 20. The storage battery supplies power to the power grid 40, and the solar power generation panel 51 is electrically connected to the storage battery.

[0034] See Figure 1 and Figure 2 In one embodiment of this application, in order to ensure that the rotating disk 60 rotates evenly and reduce vibration, two sets of insulating scrapers 70 are provided and evenly arranged on the rotating disk 60. By designing two sets of insulating scrapers 70 on opposite sides of the rotating disk 60, the dynamic balance of the rotating disk 60 can be ensured.

[0035] See Figure 3 If the insulating scraper 70 is fixedly connected to the rotating disk 60, it will be difficult to replace it after it wears out. Therefore, in one embodiment of this application, a groove 61 is provided radially on the rotating disk 60. One end of the insulating scraper 70 is slidably installed in the groove 61. An adjusting bolt 62 is screwed onto the outward end face of the groove 61. The adjusting bolt 62 is rotatably connected to the insulating scraper 70, and the adjusting bolt 62 can adjust the sliding position of the insulating scraper 70 in the groove 61. This design can adapt to different sizes of power grids 40, and also allows workers to adjust the position of the insulating scraper 70 so that it always presses against the outer wall of the power grid 40.

[0036] See Figure 3 and Figure 4 In the above embodiments, the insulating scraper 70 can be a one-piece design. However, this makes disassembly and replacement very troublesome, and long-term use can also lead to a lack of stable contact between the insulating scraper 70 and the outer wall of the power grid 40. Therefore, in one embodiment of this application, the insulating scraper 70 includes a sliding part 71 and a scraping part 72. The sliding part 71 is slidably installed in the groove 61, and one end of the sliding part 71 is rotatably connected to the adjusting bolt 62. An elastic part 73 is provided on the sliding part 71, and one end of the scraping part 72 is installed on the elastic part 73. The elastic part 73 can force the scraping part 72 to abut against the outer wall of the power grid 40. In this embodiment, the elastic part 73 is actually an elastic structure, such as a steel sheet, deformable plastic, or a spring. Its main purpose is to make the scraping part 72 abut against the outer wall of the power grid 40. This design also facilitates the replacement of the scraping part 72 by the staff later. In addition, the scraping part 72 is designed as a thin sheet structure in this application.

[0037] In the above embodiment, to facilitate better cleaning of insect carcasses adhering to the electric grid 40, bristles are provided on one side of the scraping part 72, and the bristles abut against the outer wall of the electric grid 40. The bristles can better penetrate into the electric grid 40, improving cleaning efficiency.

[0038] See Figure 3To facilitate the rotation of the rotating disk 60, in one embodiment of this application, the driving mechanism 80 includes a drive motor 81, which is mounted on the cover 50 and connected to the rotating shaft on the rotating disk 60. To ensure waterproofing, the drive motor 81 can be mounted on the back of the cover 50. The drive motor 81 can be driven by the internal power supply of the entire pest control device, or by the electrical energy generated by the device itself, such as wind or solar power, and is electrically connected to the battery in the above embodiment. It should be noted that since the rotating disk 60 is driven by the drive motor 81, and the power grid 40 does not constantly contain a large number of insect carcasses, a controller or timer can be installed on the cover 50 to control the drive motor 81 for periodic starting. Alternatively, it can be controlled manually by a switch, which is designed according to actual needs and will not be detailed here.

[0039] See you again Figure 4 In another embodiment of this application, to achieve natural drive rotation of the rotating disk 60, the drive mechanism 80 includes a drive shaft 83, which is rotatably mounted on the cover 50. One end of the drive shaft 83 is provided with a fan blade 84, and the other end of the drive shaft 83 is connected to a rotating shaft on the rotating disk 60 via a bevel gear 82. In this embodiment, natural wind power blows the fan blade 84, which drives the drive shaft 83 to rotate, thereby causing the rotating disk 60 to rotate. To better adapt to the wind direction, the entire mounting platform 20 can rotate relative to the mounting frame 10. Simultaneously, a wind deflector is provided on the cover 50, facilitating the rotation of the mounting platform 20 by natural wind power, ensuring that the fan blade 84 faces the wind direction.

[0040] It should be noted that if there is sufficient wind in the planting environment, the rotating disk 60 will be continuously driven by the fan blades 84. In this case, the rotating disk 60 and its insulating scraper 70 will interfere with insects flying towards the electric grid 40. Therefore, in some embodiments, a clutch structure is provided in the middle of the drive shaft 83, which can be manually or electrically controlled to switch the drive shaft 83 on and off when needed. Of course, in some embodiments, a limit rod can also be provided to restrict the rotation of the fan blades 84. When the fan blades 84 need to rotate, the limit rod can simply be removed.

[0041] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
