Description

Technical Field

[0001] The invention relates to the technical field of insect trapping, and in particular to an insect trapping device for preventing and controlling plant diseases and insect pests. Background Art

[0002] Plant pest and disease control is an important part of agricultural production. Its purpose is to reduce the damage of pests and diseases to crops and promote crop yields. Common pest and disease control methods include: plant quarantine, pest-resistant breeding, cultivation control, chemical control, physical and mechanical control, and biological control. Among them, the most commonly used pest and disease control method is to control pests and diseases during plant cultivation. By using insect traps to attract pests around the plants, the natural mating rate of pests is reduced, thereby reducing the insect population density of the next generation of larvae and protecting the protected plants from harm. Moreover, the use of insect traps can also reduce the use of chemical agents such as pesticides. On the one hand, it can reduce pesticide residues in plants, and on the other hand, it can prevent pesticides from polluting the environment.

[0003] At present, the most common insect trapping device in the field adopts the light trapping method, which uses the insect's tendency to light of a specific color and intensity to attract insects. Black light lamps are widely used in insect trapping, mainly emitting ultraviolet rays with a wavelength of about 365nm that are invisible to the human eye. The principle of attracting insects is that the compound eyes of insects are very sensitive to ultraviolet radiation with a wavelength of 365nm, especially flying insects. The phototropism of insects makes black light lamps in the wild at night have a strong insect-attracting effect. Pests lured by black light lamps need to be killed by chemical or electrical methods, such as the prior art publication number CN110214764A, a kind of insect-catching device that can kill fall armyworms: using an electric grid to kill the trapped pests, as shown in a plant night insect trap box with a prior art publication number CN115349504A: using insecticides to kill the trapped pests.

[0044] See also Figure 1 The present invention provides a technical solution: an insect trapping device for plant pest control, comprising a shell 1, the shell 1 is made of high temperature resistant, heat insulating and corrosion resistant materials, a mounting plate 4 is fixed to the bottom of the shell 1, and the mounting plate 4 is fixed to the ground by bolts;

[0045] An insect trap assembly 2 for attracting pests is provided on the top of the housing 1. Specifically, Figure 2-4As shown, the insect attractant assembly 2 includes a conical disk 23 fixed on the top of the shell 1 and a support frame 24 fixed on the inner wall of the top end of the shell 1, a transparent glass cover 22 is fixed on the top of the support frame 24, a lamp holder mounting seat 21 is detachably mounted on the top end of the glass cover 22, a lamp holder 26 is fixed on the top end of the lamp holder mounting seat 21, a black light bulb 25 is mounted on the bottom of the lamp holder 26, and the black light bulb 25 will emit ultraviolet rays to attract pests when powered on. Driven by their own phototaxis, the pests will automatically hit the outer wall of the glass cover 22, then fall into the conical disk 23, and finally enter the shell 1 along the inner wall slope of the conical disk 23, so that the pests can be trapped inside the shell 1.

[0046] In order to kill the trapped pests in the housing 1, the present invention provides an insect-killing component 3 for burning the pests inside the housing 1, and the insect-killing component 3 extends to the outside of the housing 1;

[0047] Specifically, Figure 2-4 As shown, the insect killing component 3 includes a turntable a31, a turntable b32 and a turntable c33 which are sequentially distributed inside the shell 1 from top to bottom. The turntable a31, the turntable b32 and the turntable c33 can separate the space inside the shell 1 into four independent and closed spaces. The spaces are named space a, space b, space c and space d in order from top to bottom. Space a is formed by the top of the turntable a31 and the inner wall of the shell 1, space b is formed by the inner wall of the shell 1 and the turntable a31 and the turntable b32, space c is formed by the inner wall of the shell 1 and the turntable b32 and the turntable c33, and space d is formed by the inner wall of the shell 1 and the bottom of the turntable c33;

[0048] In this embodiment, the turntable a31, turntable b32, and turntable c33 are all rotatably installed inside the shell 1. One side of the outer wall of the shell 1 is provided with a plurality of motors 34 for driving the turntable a31, turntable b32, and turntable c33 to flip. The model of the motor 34 is 28BYJ-48. The plurality of motors 34 are distributed on the outer wall of the shell 1 in order from top to bottom. Moreover, a protective cover 35 is fixed to the outer wall of the shell 1. The protective cover 35 covers the outside of the plurality of motors 34. The provided protective cover 35 can be used to protect the motor 34. At the same time, the protective cover 35 is provided with heat dissipation holes for exchanging and circulating the air inside the protective cover 35 with the outside air to achieve the effect of heat dissipation for the motor 34. The provided motors 34 can be used to drive the turntable a31, turntable b32, and turntable c33 to flip respectively, and the angle of each flipping is 180°.

[0049] The pests that fall into the shell 1 through the conical disk 23 will first enter the space a, and then be turned 180 degrees by the turntable a31 to pour them into the space b. The top and bottom ends of the space b are blocked by the turntable a31 and the turntable b32 respectively, and the air inside is not circulated. It is known that insects breathe through the valve-trachea system, and the valve-trachea system is used to transport oxygen in the air into the insect body and discharge carbon dioxide from the body. The present invention seals the trapped pests in the enclosed space b. As the pests breathe, the oxygen in the space b is continuously consumed and the carbon dioxide in the space b is increased. When the oxygen content is reduced, the respiration of the pests can be reduced, causing the pests to suffocate and reducing the vitality of the pests.

[0050] Then the turntable b32 can be turned over 180 degrees to turn the pests with reduced vitality into the space c. A burner 36 for igniting the pests is provided on one side of the bottom of the turntable b32. The model of the burner 36 is WM-G202-A, which is a gas burner. The ignition end of the burner 36 extends into the internal space c of the shell 1. The pests falling into the space c are ignited by the burner 36, and the pests are burned into ashes through the combustion action. During the burning process, the front and rear sides of the shell 1 are provided with a smoke guide component 39 for connecting the top space b of the turntable b32 and the bottom space c of the turntable b32. The setting of the smoke guide component 39 can pass the smoke generated by the burning of the pests into the top space b of the turntable b32 to smoke the pests to death, thereby accelerating the suffocation of the pests and making them lose vitality.

[0051] In this embodiment, a gas tank 37 for providing combustible gas to the burner 36 is provided on the top of the burner 36. In addition to combustible gas, air is also required for combustion. In the present invention, a plurality of air holes 310 are opened on the outer wall of the shell 1. The air holes 310 are connected to the space c between the turntable b32 and the turntable c33, and are used to connect to the outside to provide air for the combustion of the pests on the top of the turntable c33. A solenoid valve 38 is fixed to the outer wall of the air outlet pipe at the bottom of the gas tank 37. When burning pests, the solenoid valve 38 needs to be opened, and the gas tank 37 provides combustible gas for the combustion of the burner 36. The gas can be one of combustible gases such as natural gas and methane. The present invention is not further limited here.

[0052] In this embodiment, the structure of the smoke guide component 39 is as follows: Figure 5 and 6As shown: it includes two smoke outlets 391 and two smoke inlets 392, the two smoke outlets 391 are respectively opened at the front side and the rear side of the shell 1, and the inner walls of the smoke outlets 391 and the smoke inlets 392 are fixed with filters 395 for isolating pests and ashes, the smoke outlets 391 are connected to the space between the rotating disk b32 and the rotating disk a31, and the two smoke inlets 392 are respectively opened at the front side and the rear side of the shell 1, and the smoke inlets 392 are connected to the rotating disk b32 and the rotating disk a31. The space between the turntable a31 and the turntable b32 is connected, the outer end of the smoke outlet 391 is covered with a smoke collecting hood 393, the bottom end of the smoke collecting hood 393 is connected with a smoke pipe 394, the bottom end of the smoke pipe 394 is connected with the inside of the smoke inlet 392, and the smoke generated by the burning of pests at the top of the turntable c33 will enter into the space b between the turntable a31 and the turntable b32 through the smoke inlet 392, the smoke pipe 394, the smoke collecting hood 393 and the smoke outlet 391 in sequence.

[0053] After the pests are burned to ashes, in order to facilitate the ashes to be gathered in the middle of the top of the turntable c33, the present invention specially processes the top and bottom of the turntable c33 into a concave shape. Fig. 9 As shown, the concave shape enables the ashes on the top of the turntable c33 to gather along the inclined surface of the inner wall of the turntable c33 to the middle of the turntable c33. Moreover, the space c is used as a combustion chamber for burning pests, and high temperature will be generated during the combustion process. In order to ensure the integrity of the combustion chamber, it is required that the turntable b32 and the turntable c33 constituting the space c are made of high temperature resistant and heat insulating materials, so that the inner wall of the space c can not only withstand the hardness of the combustion effect, but also isolate the high temperature of the space c during combustion to avoid the high temperature affecting the normal use of other structural parts inside the shell 1. The shell 1 also adopts high temperature resistant, heat insulating and corrosion resistant materials. This setting is also for heat insulation and withstanding combustion, and also for preventing people from being scalded by contacting the outer wall of the shell 1, thereby improving the safety of the present invention.

[0054] Next, the motor 34 drives the turntable c33 to turn 180°, so that the ashes in the space c can be poured into the space d below. Figure 3 and 4As shown, an ash receiving hood 311 is provided at the bottom of the turntable c33. After the turntable c33 is turned 180°, the ashes of the burned pests can be poured onto the top of the ash receiving hood 311. A fan 313 for blowing air is installed inside the ash receiving hood 311. The fan 313 is a T40 axial flow fan with low noise, large air volume, high efficiency and stable wind pressure. A plurality of air outlet holes 312 with equal intervals are provided on the ash receiving hood 311. The gas blown by the fan 313 is blown toward the ashes on the top of the ash receiving hood 311 through the air outlet holes 312. A plurality of ash outlet holes 314 are provided at the bottom end of the outer wall of the shell 1. The blown ashes will be blown from the inside of the shell 1 to the surrounding land through the ash outlet holes 314. This setting can automatically clean up the dead bodies of pests after being killed, reducing the burden of manual labor. In addition, it is known that the ashes after the pests are burned contain rich mineral elements, such as phosphorus, potassium, calcium, magnesium, manganese, etc. These elements have a positive promoting effect on the growth and development of plants. Therefore, the present invention sprinkles the ashes of the burned pests on the surrounding land. The ashes can act as fertilizers, improve the fertility of the surrounding soil, promote the growth of surrounding plants, realize waste utilization, and kill two birds with one stone.

[0055] In this embodiment, the bottom edge of the ash receiving cover 311 is processed into a horizontal shape, the bottom end of the ash receiving cover 311 is flush with the bottom end of the inner cavity of the ash outlet hole 314, and the top of the ash receiving cover 311 is processed into a conical shape. Figure 7 and 8 As shown, this arrangement can facilitate the ash falling on the top of the ash receiving cover 311 to slide down along the conical slope to the plane at the bottom, and then the gas blown out of the air outlet 312 can blow it into the soil around the shell 1 through the ash outlet hole 314.

[0056] It is worth noting that the control of the electrical equipment such as the motor 34, burner 36, solenoid valve 38, fan 313 used in the present invention is automatically controlled by the controller. The controller is a main command device that can change the wiring of the main circuit or control circuit and change the resistance value in the circuit in a predetermined order to control the start, speed regulation, braking and reverse of the motor. No manual supervision is required, and the controller structure is a mature technical solution in the prior art, so it will not be further described in the present invention.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
