Description

TECHNICAL FIELD

[0001] The present application relates to the field of agricultural pest control, and particularly relates to a green pest control system for vegetable greenhouse. BACKGROUND

[0002] In modern agricultural production, vegetable greenhouses serve as important crop planting facilities and provide a stable and shell-like environment for vegetable growth. However, the warm and humid environment in the greenhouse can easily attract various pests, such as borers, whiteflies, and thrips. These pests not only directly eat the leaves, stems, and fruits of vegetables, but also can spread viruses, leading to reduced yield or even no yield of vegetables, and seriously affecting the yield and quality of crops.

[0003] Currently, among the pest control devices for greenhouse crops, the insect trapping lamp is a common green control device. The insect trapping lamp mainly utilizes the phototaxis of insects to attract pests at night through a specific wavelength light source and kill them, which can effectively reduce the number of pests at night and reduce the occurrence of pest damage. However, in actual application, it is found that the pest control effect of the insect trapping lamp in the daytime has obvious defects. During the day, the light source of the insect trapping lamp cannot form a significant attraction advantage in the natural light environment, and cannot effectively attract pests, so that the pests in the greenhouse during the day lack effective control means, and vegetables still face the risk of being damaged by pests. Therefore, it is of great practical significance to develop a green pest control system for vegetable greenhouse that can effectively control pests during the day and at night. SUMMARY

[0004] In view of the problems existing in the prior art, the present application provides a green pest control system for vegetable greenhouse, which is composed of a plurality of insect trapping and collecting devices, wherein the insect trapping and collecting device comprises:

[0005] a vertically arranged main air duct, the upper and lower ends of which are open;

[0006] The upper end of the main air duct is connected to a light guide cover, and an insect trapping lamp is arranged in the light guide cover;

[0007] An upper fan is fixed in the main air duct to guide the airflow to the bottom of the main air duct;

[0008] An annular pesticide box is arranged on the side of the main air duct, the pesticide box is filled with liquid insect trapping agent, the pesticide box and the inside of the main air duct are in communication, and the side of the pesticide box is provided with diffusion holes and a filter screen is arranged at the diffusion holes;

[0009] A conical flow guide plate is arranged at the bottom of the main air duct below the upper fan, the top end of the flow guide plate is arranged towards the side of the upper fan, the flow guide plate slides along the length direction of the main air duct, and the edge of the flow guide plate is located above the communication area of the pesticide box and the main air duct in the initial state.

[0010] By having the above technical features, the insect trapping lamp can utilize the phototaxis of insects to attract insects to fly to the side of the insect trapping lamp, and through the high-intensity wind power of the upper fan, drive the insects to enter the inside of the main air duct, and at the same time, the wind power generated by the upper fan drives the guide plate to displace, thereby driving the insects to flow to the inside of the insecticide box. Since the insecticide box has liquid insecticide placed inside, it plays a role of sinking and collecting the insects, and the air flow blows the insect trapping agent, which accelerates the diffusion of the insect trapping agent, thereby improving the insect trapping efficiency in the greenhouse.

[0011] In some embodiments, the guide plate further comprises a conical guide body and an annular flow slowing area located at the edge of the guide body. Thus, the guide body is a wind-tight structure, which, under the action of the upper fan, on the one hand, plays a role of guiding the flow of air and drives the guide plate to slide with the main air duct, and on the other hand, the flow slowing area plays a role of slowing down the air at the end and guiding the air to the inside of the insecticide box, further reducing the resistance of the air flow, and making the guiding effect on the insects more significant.

[0012] In some embodiments, a limiting slide rod is coaxially arranged at the middle part of the main air duct, the limiting slide rod is fixed with the main air duct, the guide body is coaxially arranged at the top end of the limiting slide rod, a spring is sleeved on the limiting slide rod, the bottom of the spring is provided with a limiting piece fixed with the limiting slide rod, and the two ends of the spring are respectively abutted against the guide body and the limiting piece. Thus, the limiting slide rod plays a role of limiting and fixing the guide plate, and when the upper fan is working, the wind power generated by the upper fan is greater than the elastic force of the spring, which drives the guide plate to slide with the limiting slide rod, thereby connecting the flow of air and the space inside the insecticide box.

[0013] In some embodiments, a boosting device is arranged on the guide plate, which drives the guide plate to rotate under the wind pressure and sweeps the communication area of the main air duct and the insecticide box. The boosting device comprises stirring blades, which are arranged in multiple and circumferentially distributed on the surface of the guide body; and a sweeping assembly, which is fixed to the edge of the flow slowing area and acts on the communication area of the main air duct and the insecticide box. Thus, under the cooperation of the wind pressure, the blowing of the stirring blades drives the guide plate to rotate around the limiting slide rod, which realizes the passive rotation of the guide plate, and makes the sweeping assembly act on the communication area of the main air duct and the insecticide box, which on the one hand, is conducive to boosting the insects to enter the inside of the insecticide box, and on the other hand, is not easy to cause the blockage of the communication area of the main air duct and the insecticide box.

[0014] In some embodiments, the brush assembly comprises a base fixed to the surface of the circulating area; and a plurality of bristles fixed to the base and extending towards the edge of the slow flow area. Thus, the bristles can sweep the insects in the main air duct and the insect box communication area, accelerating the insects into the insect box. In addition, the bristles can keep the main air duct and the insect box communication area smooth, ensuring the smooth entry of the insects.

[0015] In some embodiments, the main air duct is provided with a pest-reducing flow guide mechanism on the side thereof, which comprises

[0016] A plurality of atomizing nozzles are provided on the side of the main air duct and above the flow guide plate.

[0017] A water pump is provided, with the input end thereof in communication with the interior of the insect box and the output end thereof in communication with the atomizing nozzles. Thus, the operation of the atomizing nozzles improves the contact efficiency of the liquid and the insects, increases the weight of the insects, and makes the flight of the insects more difficult. In addition, the liquid splashed onto the flow guide plate also increases the smoothness of the flow guide plate, prevents the insects from adhering thereto, and improves the flow guiding efficiency of the air to the insects. Furthermore, the liquid is an insect attractant, which makes rational use of the resources of the device. In addition, the flow guide plate plays a role in guiding the liquid, reducing the waste of the insect attractant.

[0018] In some embodiments, a limiting ring is annularly provided on the inner wall of the main air duct and located below the main air duct and the insect box communication area. Thus, the limiting ring limits the final sliding position of the flow guide plate, and also collects the excess insect attractant.

[0019] In some embodiments, a plurality of water inlet holes are provided on the connection between the limiting ring and the main air duct and in communication with the insect box. Thus, the collected insect attractant on the limiting ring can be guided and returned to the insect box, reducing the waste of the insect attractant.

[0020] In some embodiments, a limiting block is detachably connected to the top end of the limiting slide rod. Thus, the limiting block limits the mutual disengagement of the flow guide plate and the limiting slide rod, ensuring the stability of the mutual connection between the flow guide plate and the limiting slide rod.

[0021] In some embodiments, the limiting block is spherical. Thus, on the one hand, the resistance to air flow can be reduced, and on the other hand, the smooth surface of the limiting block can prevent the insects from staying.

[0022] It should be understood that the content described in the summary section is not intended to limit the key or important features of the embodiments of the present disclosure, nor to limit the scope of the present disclosure. Other features of the present disclosure will become apparent through the following description. BRIEF DESCRIPTION OF DRAWINGS

Figure 2 As shown, the main air duct 1 is provided with an upper fan 2 below the light guide cover 11, the upper fan 2 is coaxially arranged with the main air duct 1 and is fixedly connected with the main air duct 1, so that when the upper fan 2 is started, air flows from the upper end of the main air duct 1 to the lower part of the main air duct 1.

[0036] The side of the main air duct 1 is provided with an annular pesticide box 3, a plurality of air flow ports 31 are formed in the inner annular arm of the pesticide box 3 and are in communication with the inside of the main air duct 1, a plurality of diffusion holes 32 are formed in the outer annular arm of the pesticide box 3 and are in communication with the outside environment, and a filter screen 33 is fixedly arranged around each diffusion hole 32, so that air flows smoothly, and at the same time, the insects are prevented from escaping from the inside of the main air duct 1 through the diffusion hole 32 area.

[0037] Further, the pesticide box 3 is filled with liquid insect attractant, the insect attractant can be a sex pheromone type insect attractant, which takes insect sex pheromone as a core component, attracts male pests by simulating the sex pheromone released by female pests, and thus destroys the mating and reproduction of the pests.

[0038] The inside of the main air duct 1 is coaxially provided with a guide plate 4 below the upper fan 2, the guide plate 4 is slidable with the main air duct 1, the guide plate 4 is in the form of a cone, the tip area thereof faces one side of the upper fan 2 and is slidably connected with the main air duct 1 along the length direction of the main air duct 1.

[0039] Specifically, Figure 3 As shown, the vegetable greenhouse green insect prevention system provided by the embodiment comprises a plurality of insect collecting devices, wherein the insect collecting device comprises a vertical main air duct 1, the upper and lower ends of the main air duct 1 are both provided with openings, the upper end is fixedly connected with a light guide cover 11, the light guide cover 11 is fixedly connected with an insect attracting lamp 12, and in actual application, hook bodies or other hanging structures can be additionally arranged on the side of the main air duct 1, so that the device can be hung in the top area of the greenhouse. Figure 3As shown, the flow guide plate 4 comprises a tapered flow guide body 41, and the edge of the flow guide body 41 is smoothly provided with an annular flow slowing area 42, so as to slow down the high-speed flow rate of air in the flow guide body 41 and smoothly guide the air to each air flow port 31, greatly reducing the air flow resistance.

[0040] Figure 4 An explosion schematic view of the sliding structure of the flow guide plate 4 in a vegetable greenhouse green insect prevention system insect collecting device is shown. Figure 4 As shown, the middle part of the main air cylinder 1 is coaxially provided with a limiting sliding rod 51, and the bottom end of the limiting sliding rod 51 is fixed to the inner wall of the main air cylinder 1 through a plurality of supporting rods. A limiting sheet 52 is coaxially fixed on the limiting sliding rod 51, and a spring 53 is arranged above the limiting sheet 52, the spring 53 is sleeved on the limiting sliding rod 51, the above-mentioned flow guide plate 4 is coaxially arranged at the upper end of the limiting sliding rod 51, and a limiting block 54 is threadedly connected at the upper end of the limiting sliding rod 51, so as to limit the mutual disengagement of the flow guide plate 4 and the limiting sliding rod 51.

[0041] Further, the limiting block 54 is a circular block, on the one hand, its smooth surface can reduce the resistance between the flowing air, on the other hand, it is also not easy to provide a foothold area for insects, and the guidance and flow of insects in the main air cylinder 1 are guaranteed.

[0042] When the insect collecting device works, the insect lamp 12 and the upper fan 2 are started at the same time, the insect lamp 12 uses the phototaxis of insects in the night environment to attract insects to the side of the insect lamp 12, the wind power generated by the start of the upper fan 2 drives the high-speed flow of air, and drives the insects in the light guide cover 11 to enter the inside of the main air cylinder 1 through the upper port of the main air cylinder 1, at the same time, the upper fan 2 is started, the wind pressure generated by the upper fan 2 drives the spring 53 to be elastically compressed, so that the air flow port 31 of the pesticide box 3 is exposed at the end of the flow guide plate 4, so that the high-speed airflow carries the insects into the inside of the pesticide box 3, and part of the insects contact the insect attractant, so as to increase their own weight, which cannot fly and float on the surface of the insect attractant; the flowing gas will be discharged through the diffusion hole 32, so as to guarantee the smooth flow of the gas, and the flow of air will also accelerate the insect attractant to quickly spread to the environment, so as to improve the attraction efficiency of insects in the daytime environment.

[0043] Further, in order to improve the efficiency of insects entering the pesticide box, a plurality of stirring leaves are arranged on the flow guide plate, the stirring leaves are arranged obliquely on the surface of the flow guide body of the flow guide plate, and a plurality of stirring leaves are arranged and distributed in a circle on the surface of the flow guide body.

[0044] The brush assembly is arranged on the mixing flow area and comprises a base fixed on the surface of the slow flow area, and a plurality of bristles are fixed on one side of the base and extend towards the edge of the slow flow area. During rotation of the flow guide plate, the bristles simultaneously sweep the air flow passage area of the main air cylinder, thereby playing a driving role on the insects in the area and accelerating the efficiency of the insects entering the pesticide box. Moreover, the bristles are elastic, and during rotation of the flow guide plate, the bristles are always applied to the air flow passage area and can also sweep floating hairs in the air, so as to prevent the air flow passage area from being blocked.

[0045] Figure 5 Fig. 1 shows a schematic view of the outer arm structure of the main air cylinder in a vegetable greenhouse green insect prevention system insect trapping and collecting device according to an embodiment of the present application. Figure 5 As shown in the figure, in order to improve the transportation efficiency of air on insects, a pest-reducing flow guide mechanism 6 is arranged in the main air cylinder 1, the pest-reducing flow guide mechanism 6 comprises a plurality of atomizing nozzles 61 arranged on the periphery of the main air cylinder 1, and the atomizing nozzles 61 are located below the upper air fan 2; the periphery of the main air cylinder 1 is also provided with a water pump 62, the input port of the water pump 62 is connected to the bottom of the pesticide box 3 through a pipe, and the output port of the water pump 62 is connected to each atomizing nozzle 61 through a pipe, so that when the upper air fan 2 is started, the water pump 62 is also started, and the water vapor sprayed by the atomizing nozzle 61 will adhere to the insects, thereby increasing the weight of the insects and making it more difficult for the insects to overcome the force applied by the air, thereby improving the transportation efficiency of the high-speed air flow on insects. Moreover, the water mist flowing to the surface of the flow guide plate 4 makes the surface of the flow guide plate 4 smoother, and the insects are more difficult to adhere to the surface of the flow guide plate 4. Further, the flow guide plate 4 also guides the excess liquid to the edge and enters the pesticide box 3 again through the air flow passage 31, thereby greatly reducing the waste of liquid pesticide.

[0046] Figure 6 Fig. 2 shows a schematic view of the flow guide plate area structure in a vegetable greenhouse green insect prevention system insect trapping and collecting device according to an embodiment of the present application. Figure 6As shown, in order to reduce the waste of liquid medicine, the main air cylinder 1 is further provided with a limiting ring piece 15, which is fixed to the inner wall of the main air cylinder 1 and located below the air flow passage 31. On the one hand, after the upper fan 2 is started, the guide plate 4 is driven to slide in the main air cylinder 1, and the limiting ring piece 15 supports the edge of the guide plate 4 to limit the sliding length of the guide plate 4; on the other hand, a gap is left between the edge of the guide plate 4 and the inner wall of the main air cylinder 1, and the medicine sprayed by the atomizing nozzle 61 will inevitably flow downward along the length direction of the inner wall of the main air cylinder 1, so the limiting ring piece 15 can also support the excess liquid, and a plurality of water inlet holes 16 are formed at the connection between the limiting ring piece 15 and the main air cylinder 1 and are in communication with the inside of the medicine box 3, so that the excess liquid flows back to the medicine box 3 through the water inlet holes 16, greatly reducing the waste of liquid medicine.
