Description

Technical Field

[0001] This utility model belongs to the field of agricultural pest control technology, and in particular relates to an agricultural pest control device. Background Technology

[0002] In agricultural production, to prevent pests such as aphids from damaging crops, yellow sticky traps or black light lamps are used as baits to trap and kill aphids, thereby reducing their damage to crops.

[0003] The principle behind using black light lamps as traps to kill aphids is as follows: taking advantage of aphids' phototaxis, the black light lamp is turned on at night to attract aphids. When the aphids fly close to the black light lamp, they are electrocuted by the electric grid set up on the outside of the lamp. After being electrocuted, the aphid corpses will stick to the surface of the electric grid. Over time, this will affect the electrocution effect of the electric grid, so it is necessary to clean the aphid corpses on the surface of the electric grid regularly.

[0004] Currently, aphids are usually removed by manually wiping the surface of the electric grid with a cloth. This cleaning method directly causes the aphids to break and soil the cloth, requiring the cloth to be replaced frequently, which affects the aphid removal rate on the electric grid surface. At the same time, some of the broken aphid corpses can enter the gaps in the electric grid, affecting the electric shock effect of the grid. Utility Model Content

[0005] In view of this, the present invention aims to provide an agricultural pest control device to quickly remove aphids from the surface of the electric grid, thereby ensuring the effectiveness and efficiency of the electric grid in killing aphids.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] An agricultural pest control device includes a lower plate mounted on a support frame, with an upper plate directly above the lower plate. Both the upper and lower plates are insulating plates connected by double-headed bolts. A black light is positioned at the center of the bottom surface of the upper plate, and an electric grid is arranged around the black light. The electric grid has an inverted conical structure. An annular air inlet pipe is positioned at the upper part of the annular space formed between the electric grid and the black light. The air inlet pipe is connected to the upper plate by a hanger. The air outlet of the air inlet pipe is inclined outward and downward. A fan is mounted on the top surface of the upper plate, and the air inlet of the air inlet pipe is connected to the air outlet of the fan through a pipe.

[0008] Furthermore, the lower plate has an annular trough corresponding to the power grid, the trough penetrating the upper and lower surfaces of the lower plate, and the two side walls of the trough are connected by radially arranged crossbars.

[0009] Furthermore, a collection box is detachably installed on the bottom surface of the lower plate, and the collection box has an annular groove that is directly opposite the drop trough.

[0010] Furthermore, the collection box is an annular groove structure, fitted outside the bracket. The top surface of the collection box has an outer edge corresponding to the lower plate. The outer edge fits into the bottom surface of the lower plate and is connected to the lower plate by the double-headed bolts.

[0011] Furthermore, the double-ended bolt has limiting rings at the external thread positions near the upper and lower ends, respectively. The external thread at the lower end passes through the lower plate, and the corresponding limiting ring abuts against the top surface of the lower plate. The external thread at the upper end passes through the upper plate, and the corresponding limiting ring abuts against the bottom surface of the upper plate. The external thread at the upper and lower ends is matched with nuts. The double-ended bolt connects and fixes the lower plate and the upper plate.

[0012] Furthermore, several protective rods are installed around the power grid on the bottom surface of the upper plate.

[0013] Furthermore, the bracket includes a column, a support plate is provided at the top of the column and a base is provided at the bottom, and the lower plate is supported by the support plate and fixed by screws to the support plate.

[0014] Compared with existing technologies, the agricultural pest control device described in this utility model has the following advantages:

[0015] In this invention, the electric grid adopts an inverted cone-shaped structure, and an air inlet pipe is set at the upper part of the internal space of the electric grid. Air is blown into the air inlet pipe, and under the action of wind force and the gravity of the aphids themselves, the aphid corpses adhering to the surface of the electric grid fall off quickly, keeping the surface of the electric grid clean and enabling the electric grid to maintain its good function of electrocution of aphids.

Detailed Implementation

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] like Figure 1 As shown, an agricultural insecticidal device includes a support frame, which is an insulated support frame, such as one made of insulating material or coated with insulating paint. The support frame includes a column 1, a lower plate 3, and an upper plate 8. A support plate 12 is provided at the top of the column 1, and a base 11 is provided at the bottom. The base 11 has several fixing holes. When using this device to attract and kill aphids, the device can be placed on the ground and the base can be fixed to the ground with ground nails. The lower plate 3 and the upper plate 8 are preferably circular insulating plate structures, such as those made of insulating material or coated with insulating paint. The lower plate 3 is installed on the top surface of the support plate 12 with screws, and the upper plate 8 is located directly above the lower plate 3. The upper plate 8 and the lower plate 3 are connected and fixed in the circumferential direction by several double-ended bolts 4, which are made of insulating material or coated with insulating paint. An electric grid 6 is provided at the center of the bottom surface of the upper plate 8. The electric grid 6 has an inverted conical structure. The annular space formed between the electric grid 6 and the black light 7 is created by the black light 7 emitting light that attracts aphids. When aphids fly towards the black light and touch the electric grid 6, they are electrocuted and killed. The electric grid 6 and the black light 7 can be electrically connected to the mains power supply via power lines, or they can be connected to a battery via power lines. The opening and closing of the electric grid 6 and the black light 7 can be controlled manually or remotely. Remote control of the opening and closing of electrical equipment is existing technology and will not be described in detail here. An air inlet pipe 9 is suspended from the bottom of the upper plate 8 by a hanger rod. The air inlet pipe 9 is located at the upper part of the annular space formed by the electric grid 6 and the black light 7. The air inlet pipe 9 has an outlet that slopes outward and downward, allowing air to blow towards the electric grid 6. A fan 10 is installed on the top surface of the upper plate 8, and the air inlet of the air inlet pipe 9 is connected to the outlet of the fan 10 via a pipe. The fan 10 can be electrically connected to the mains power via a power cord, or it can be connected to a battery via a power cord. Similarly, the fan 10 can be manually controlled or connected to a remote control terminal to control the fan 10 to start.

[0025] In this invention, the electric grid 6 adopts an inverted cone-shaped structure, and an air inlet pipe is installed inside the electric grid. The air inlet pipe 9 blows air from the inside to the outside towards the electric grid, so that the aphid corpses adhering to the surface of the electric grid 6 will fall off quickly, thereby achieving rapid cleaning of the electric grid surface and maintaining the electric grid 6 in good electric shock effect.

[0026] In this utility model, the lower plate 3 has the following structure: Figure 2 As shown, a ring-shaped trough 31 is provided corresponding to the power grid 6. The trough 31 penetrates the upper and lower surfaces of the lower plate 3, and the two side walls of the trough 31 are connected by radially arranged crossbars 32. A collection box 2 is detachably installed on the bottom surface of the lower plate 3. The structure of the collection box 2 is as follows: Figure 3 As shown, it is an annular groove structure, fitted onto the support plate 12 of the bracket. The corresponding groove 31 of the collection box 2 has an upward-facing annular groove 24, and the top surface of the outer wall of the annular groove is provided with an outer eave 25 corresponding to the lower plate 3. The installation structure of the collection box 2 is as follows. Figure 1 As shown, its outer edge 25 is attached to the bottom surface of the lower plate 3 and connected to the lower plate 3 by double-headed bolts 4. At this time, since the groove 31 of the lower plate corresponds to the electric grid 6, and the annular groove 24 of the collection box 2 is directly opposite the groove 31, when the aphids on the surface of the electric grid 6 are cleaned, the fallen aphids fall into the annular groove 24 of the collection box 2 through the groove 31 of the lower plate 3 for collection.

[0027] In this utility model, the double-headed bolt 4 structure is as follows: Figure 4 As shown, limiting rings 41 are respectively provided at the positions of the external threaded portions 42 near the upper and lower ends. During assembly, the external threaded portion 42 at the lower end of the double-ended bolt 4 passes through the lower plate 3, and the corresponding limiting ring 41 abuts against the top surface of the lower plate 3. The external threaded portion 42 at the upper end passes through the upper plate 8, and the corresponding limiting ring 41 abuts against the bottom surface of the upper plate 8. The external threaded portions 42 at the upper and lower ends are each matched with nuts, and the double-ended bolt 4, the lower plate 3, and the upper plate 8 are connected and fixed by the nuts.

[0028] To enhance the safety of this device, several protective rods 5 are installed around the electric grid 6 on the bottom surface of the upper plate 8. These protective rods are made of insulating material or coated with insulating paint. The protective rods prevent personnel from easily touching the electric grid, thus improving the safety of the device.

[0029] 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.
