Description

Technical Field

[0001] The present invention relates to the technical field of agricultural plant protection, in particular to a pest trapping and killing device for agricultural plant protection. Background Art

[0002] With technological advancements, modern agriculture is gradually moving towards intelligent and green development. Smart agriculture, with its high efficiency, environmental friendliness, and intelligent capabilities, is profoundly changing the face of traditional agriculture. Pest trapping devices, a key component of green pest control technology, are a key component of this approach. Pests are increasingly damaging crops. While traditional chemical pesticide control methods are effective, long-term use can lead to increased pest resistance. Furthermore, chemical pesticide residues can pollute the environment and impact the safety and quality of agricultural products.

[0003] In this context, physical pest trapping devices have emerged to protect agricultural plants. However, after the surrounding ground and underground pests are attracted and killed, in order to improve the trapping effect, the position needs to be changed frequently. Most existing pest trapping devices are fixed in a certain place and can only cover a limited range, or only have rollers installed under the pest trapping devices for manual movement. When the position is changed frequently, the labor intensity is relatively high. Therefore, a pest trapping device for protecting agricultural plants is provided. Summary of the Invention

[0004] The purpose of the present invention is to provide an insect trapping device for protecting agricultural plants, which has the effect of automatically changing its insect trapping position, reducing manual intervention, weakening manual labor intensity, expanding the insect trapping range, extending the coverage range, and improving insect killing efficiency.

[0007] A driving mechanism is provided on the side of one of the support columns. The driving mechanism includes a box body fixedly connected to the side of the support column. Inside the box body, there is a wireless receiving module and a motor forward and reverse module that are electrically connected to each other. It also includes a passive gear fixedly connected to the end of the belt pulley. The bottom end of the box body is fixedly connected to a motor, and the output end of the motor is fixedly connected to an active gear. The outer surface of the support column is rotatably connected to a transmission wheel that meshes with and drives the passive gear and the active gear. The motor is electrically connected to the motor forward and reverse module.

[0008] By adopting the above technical solution, through the cooperation setting among the support column, the motor, the active gear, the transmission wheel, the passive gear, the box body, the belt, the support rod, the support cylinder, the control box, the connecting plate and the belt pulley, the support column is inserted into the soil to support the belt pulley and the belt. The belt is used to support and drive the control box. The support rods are inserted at certain intervals in sequence. The belt is supported by the support rods and the support cylinder. When in use, the corresponding program is input into the PLC programmable controller. The PLC programmable controller transmits the electrical signal to the time relay module, and a certain interval time is set. The time relay module transmits the electrical signal to the motor forward and reverse module through the wireless sending module and the wireless receiving module. The forward and reverse rotation of the motor is realized through the motor forward and reverse module. The motor drives the passive gear to rotate through the transmission wheel, and the passive gear drives the belt pulley to rotate, thereby driving the belt to move, so as to realize the forward and reverse rotation of the belt, drive the control box, the first insect trapping mechanism and the second insect trapping mechanism to perform automatic reciprocating motion, reduce manual intervention, automatically change the insect trapping position, expand the coverage range. In summary, the device of the present invention can automatically change the insect trapping position, reduce manual intervention, weaken the manual labor intensity, expand the insect trapping range, expand the coverage range, improve the insect killing efficiency, and improve the agricultural production efficiency.

[0014] By adopting the above technical solution, when the electrocuted flying insects fall on the umbrella-shaped body, they can fall to the ground along the umbrella-shaped body, avoiding the accumulation of flying insects in the control box. At the same time, when the first electric telescopic rod moves downward, the energized column on the first cylindrical power grid contacts the second through hole, and the umbrella-shaped body can also clean the flying insects stuck to the energized column, saving the trouble of cleaning the flying insects, reducing the manual participation, and lowering the labor intensity.
