Description

Psyllid trapping device for loquat orchards Technical Field

[0001] This invention relates to the field of psyllid trapping devices, specifically to a psyllid trapping device for loquat orchards. Background Technology

[0002] Psyllids are a regional pest of loquats, primarily damaging flower spikes and young fruits, followed by tender leaves and shoots. The peak infestation periods for psyllids are March-April and October-December each year. Infected loquats develop a milky-white secretion from the psyllids, which can further lead to sooty mold, causing damage to the surface of the fruit and hindering the normal growth of young fruit, thus reducing fruit quality.

[0003] Existing psyllid trapping devices typically use high-voltage electric grids to kill psyllids. For example, there is a citrus psyllid trapping device with announcement number CN213663261U and a citrus psyllid trapping device and trapping method with announcement number CN105580791A. Although both of these electric grids can kill psyllids, they are fixed and cannot be moved. Psyllids need to fall onto the electric grid to be killed, resulting in a relatively small area where the electric grid can kill psyllids. Summary of the Invention

[0004] In view of the above-mentioned problems in the prior art, the present invention provides a psyllid trapping device for loquat orchards, which solves the problem that the psyllid killing range is small due to the fixed electric grid in the existing psyllid trapping devices.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A psyllid trapping device for loquat orchards is provided, comprising a main body, the main body including a fixed box, the outer wall of the fixed box having at least one insect inlet; the interior of the fixed box is provided with a trapping component for attracting psyllids, a rotating rod is rotatably mounted on the lower surface of the top plate of the fixed box, an electric grid component is fixed on the rotating rod, and the rotating rod drives the electric grid component to rotate around the trapping component.

[0007] In this solution, psyllids are attracted into the fixed box by the trapping component. The rotating rod drives the electric grid component to rotate around the trapping component, so that the electric grid component can kill psyllids in the entire annular area of ​​the fixed box. At the same time, the psyllids on the electric grid component will fall off due to gravity and will not remain on the electric grid component, so there is no need to set up an additional cleaning component.

[0008] Furthermore, the trapping assembly includes a lifting component fixed inside the fixed box. A conical frame is fixed to the lifting component, and a conical electric grid is installed inside the conical frame. A support platform is fixed in the middle of the conical frame, and a trap is fixed on the support platform. Psyllids will gather on the trap. The lifting component can drive the conical frame and the trap to move back and forth in the vertical direction to a certain extent, creating a shaking motion. The shaking of the trap will cause multiple psyllids to fall. Psyllids flying in the air will be killed by the rotating electric grid component, while psyllids that fall directly onto the conical frame will be killed by the conical electric grid. The shaking of the conical electric grid will also shake the killed psyllids off through its gaps or outer edges.

[0009] Furthermore, the trap includes a biomimetic plant coated with psyllid sex pheromones and volatile organic compounds from plants, with light strips wrapped around it. The biomimetic plant can be in the shape and color of citrus branches, loquat branches, or Murraya paniculata, and it can release volatile organic compounds from the plant. Thus, the shape and color of the biomimetic plant, the volatile organic compounds, the psyllid sex pheromones, and the light strips all attract psyllids, greatly improving the trapping rate.

[0010] Furthermore, the outer diameter of the tapered frame is smaller than the inner diameter of the fixed box.

[0011] Furthermore, the lifting assembly includes four telescopic rods that are vertically fixed around the bottom of the conical frame. The bottom end of each telescopic rod is fixed to the inner wall of the fixed box, and the bottom edge of the conical frame is fixedly connected to the slider in the screw-slider mechanism through the fixed rod. The base of the screw-slider mechanism is fixed to the inner wall of the fixed box.

[0012] Furthermore, the power grid component includes a rectangular fixed frame, within which a power grid is disposed.

[0013] Furthermore, a cylindrical plate is slidably installed inside the wall of the fixed box. A protrusion is provided at the bottom end of the cylindrical plate, and the protrusion is slidably mounted on the inner wall of the fixed box. The protrusion is fixedly connected to an electric push rod fixed to the inner wall of the fixed box. The electric push rod drives the cylindrical plate to open or close each insect inlet. The cylindrical plate can close the insect inlets, thereby sealing the fixed box and preventing psyllids from escaping.

[0014] Furthermore, the rotating rod is electrically connected to the rotating motor, and the rotating motor, the electric grid assembly, the trapping assembly, and the electric push rod are all electrically connected to the controller, which is electrically connected to the battery located inside the fixed box.

[0015] Furthermore, a solar panel is installed on the top of the mounting box, and the solar panel is electrically connected to the battery. The solar panel can provide a certain amount of electricity, reducing the frequency of battery replacement.

[0016] Furthermore, the fixed box is equipped with a pull-out box, which is shaped like an inverted cone. A garbage bag can be placed inside the pull-out box to facilitate the removal of the killed psyllids.

[0017] This invention discloses a psyllid trapping device for loquat orchards, which has the following advantages:

[0018] This invention attracts psyllids into a fixed box using a trapping component. A rotating rod drives an electric grid component to rotate around the trapping component, allowing the electric grid component to kill psyllids in the entire annular area within the fixed box. This increases the killing range, and the psyllids on the electric grid component will fall off due to gravity, preventing them from remaining on the component and eliminating the need for an additional cleaning component.

[0024] The specific embodiments of the present invention are described below to enable those skilled in the art to understand the present invention. However, it should be understood that the present invention is not limited to the scope of the specific embodiments. For those skilled in the art, various changes are obvious as long as they are within the spirit and scope of the present invention as defined and determined by the appended claims. All inventions utilizing the concept of the present invention are protected.

[0025] Referring to Figure 1, this embodiment provides a psyllid trapping device for loquat orchards, including a device body, which includes a cylindrical fixed box 1, a rotating rod 2, an electric grid assembly 3, and a trapping assembly 4.

[0026] At least one insect inlet 11 is provided on the outer wall of the fixed box 1; the insect inlet 11 can be a round hole or a rectangular hole. In order to increase the trapping rate of psyllids, in this embodiment, the insect inlet 11 is the entire annular surface, as shown in Figure 3. The disconnection of the fixed box 1 is fixedly connected by multiple connecting columns.

[0027] Referring to Figures 1 and 2, a cylindrical plate 5 is slidably disposed within the wall of the fixed box 1. A protrusion is provided at the bottom end of the cylindrical plate 5, and the protrusion is slidably disposed within a groove on the inner wall of the fixed box 1 and exposed externally. The protrusion is fixedly connected to an electric push rod 6 fixed to the inner wall of the fixed box 1. The electric push rod 6 drives the cylindrical plate 5 to open or close the insect inlet 11. The cylindrical plate 5 can close the insect inlet 11, thereby sealing the fixed box 1 and preventing the psyllid from escaping.

[0028] The fixed box 1 contains a trapping assembly 4 for attracting psyllids. A rotary motor 21 with a speed reducer is installed on the lower surface of the top plate of the fixed box 1. A rotating rod 2 is installed on the output end of the rotary motor 21, and an electric grid assembly 3 is fixed on the rotating rod 2. The rotating rod 2 drives the electric grid assembly 3 to rotate around the trapping assembly 4. The electric grid assembly 3 includes a rectangular fixed frame 31, and an electric grid 32 is installed inside the fixed frame 31.

[0029] A solar panel 12 is installed on the top of the fixed box 1, and the solar panel 12 is electrically connected to the battery 8. The solar panel 12 can provide a certain amount of electricity, reducing the frequency of battery 8 replacement.

[0030] The fixed box 1 is equipped with a pull-out box 7 located below the conical frame 44. The pull-out box 7 is in the shape of an inverted cone. A garbage bag can be placed inside the pull-out box 7 to facilitate the removal of the killed psyllids.

[0031] The rotary motor 21, the electric grid assembly 3, the trapping assembly 4, and the electric push rod 6 are all electrically connected to the controller 9, which is electrically connected to the battery 8 located inside the fixed box 1. The MCU in the controller 9 can be a PLC or a microcontroller, and the controller 9 can be electrically connected to a thermal imaging sensor located on the top plate of the fixed box 1. The controller 9 obtains the number and density of psyllids through thermal imaging images obtained by the thermal imaging sensor.

[0032] In this embodiment, the trapping component 4 attracts psyllids into the fixed box 1 through the insect inlet 11. The rotating rod 2 drives the electric grid component 3 to rotate around the trapping component 4, so that the electric grid component 3 can kill psyllids in the entire annular area of ​​the fixed box 1. While increasing the killing range, the psyllids on the electric grid component 3 will fall off due to gravity and will not remain on the electric grid component 3, so there is no need to set up an additional cleaning component.

[0033] Specifically, the trapping component 4 includes a lifting component fixed inside the fixed box 1. A conical frame 44 is fixed on the lifting component. The outer diameter of the conical frame 44 is smaller than the inner diameter of the fixed box 1, so that the woodlice can fall out from the gap between the conical frame 44 and the fixed box 1.

[0034] Referring to Figure 4, a conical electric grid 45 is installed inside the conical frame 44, and a support platform 46 is fixed in the middle of the conical frame 44. A trap 47 is fixed on the support platform 46. Psyllids will gather on the trap 47. The lifting component can drive the conical frame 44 and the trap 47 to move back and forth in the vertical direction to a certain extent, creating a shaking motion. The shaking of the trap 47 will cause multiple psyllids to fall. Psyllids flying in the air will be killed by the rotating electric grid component 3, while psyllids that fall directly onto the conical frame 44 will be killed by the conical electric grid 45. The shaking conical electric grid 45 will shake the killed psyllids off from its gaps or outer edges.

[0035] The lifting assembly of this embodiment includes four telescopic rods 41, each vertically fixed around the bottom of the conical frame 44. The bottom end of each telescopic rod 41 is fixed to a support plate on the inner wall of the fixed box 1. The bottom edge of the conical frame 44 is fixedly connected to the slider in the lead screw and slider mechanism 42 via a fixing rod 43. The base of the lead screw and slider mechanism 42 is fixed to the inner wall of the fixed box 1. The lead screw and slider mechanism 42 is prior art and includes a base, a motor, a lead screw, and a slider. Since it is prior art, its specific working principle and connection relationship will not be described in detail in this embodiment.

[0036] In this embodiment, the trap 47 includes a biomimetic plant coated with psyllid sex pheromones and volatile organic compounds from plants, with a light strip wrapped around it. The biomimetic plant can be in the shape and color of citrus branches, loquat branches, or Murraya paniculata, and it can release volatile organic compounds from the plant. Thus, the shape and color of the biomimetic plant, the volatile organic compounds, the psyllid sex pheromones, and the light strip all attract psyllids, greatly improving the trapping rate.

[0037] The working principle of this solution is as follows:

[0038] The insects are attracted by the shape and color of biomimetic plants, volatile organic compounds, psyllid sex pheromones, and light strips. The electric push rod 6 is activated to move the cylindrical plate 5 upward to seal the insect inlet 11. The lifting component drives the conical frame 44 and the trap 47 to move back and forth in the vertical direction to a certain extent to create a shaking motion. The shaking of the trap 47 will cause multiple psyllids to fall. The psyllids flying in the air will be killed by the rotating electric grid component 3, while the psyllids that fall directly onto the conical frame 44 will be killed by the conical electric grid 45. The shaking conical electric grid 45 will shake the killed psyllids from the gaps or outer edges into the pull-out box 7.

[0039] Although specific embodiments of the invention have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Various modifications and variations that can be made by a person skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of this patent.
