However, it still has the following defects:

[0003] Using insect traps to trap and kill flying animals is a slow method that requires replacing the traps, resulting in poor insect control. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a pest control device for greenhouses, which effectively solves the problems of slow pest control speed of insect traps, the need to replace insect traps, and poor pest control effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pest control device for greenhouses, comprising a support base, an insect-killing horizontal cylinder above the support base, a bottom block fixedly installed at the bottom end of the insect-killing horizontal cylinder, a first rotating block fixedly installed at the bottom end of the bottom block, a first rotating frame fixedly installed at the top end of the support base, the first rotating frame comprising two fixed plates and a fixed shaft between the two fixed plates, the first rotating block being rotatably connected to the fixed shaft, a spiral spring being installed between the first rotating block and the fixed shaft, and a movable crushing assembly being installed inside the insect-killing horizontal cylinder;

[0006] The mobile crushing assembly includes a light source pressing block movably installed inside the insect-killing horizontal cylinder. The outer wall of the light source pressing block contacts the inner wall of the insect-killing horizontal cylinder. The light source pressing block consists of an outer cylindrical glass shell and an internal light source.

An insect-killing control assembly is installed on the insect-killing horizontal cylinder.

[0007] Preferably, the movable balancing component includes a top box fixedly installed at the top of the insect-killing horizontal cylinder. An internal block is movably installed inside the top box. Second side rods are symmetrically fixedly installed on both sides of the internal block. The ends of the two second side rods extend to both ends of the top box. A longitudinal connecting plate is installed at the ends of the two second side rods that are far apart from each other. The two longitudinal connecting plates are fixedly connected to two limiting plates respectively. A first spring is symmetrically installed on both sides of the internal block. The end of the first spring is fixedly connected to the inner wall of the end of the top box.

[0008] Preferably, the snap-fit ​​fastener includes a positioning groove formed on the first side rod, the positioning groove being located on the outside of the insect-killing horizontal cylinder, side plates being symmetrically installed at both ends of the insect-killing horizontal cylinder, a screw cylinder being installed on the side plate, a positioning bolt being installed on the internal thread of the screw cylinder, and the bottom end of the positioning bolt being snapped into the interior of the positioning groove.

[0009] Preferably, the extermination control component includes symmetrically formed arc-shaped grooves on the outer walls of both ends of the insect-killing horizontal cylinder. The cross-section of the arc-shaped grooves is convex. The bottom of the arc-shaped grooves is symmetrically provided with insect inlet and outlet grooves. The two insect inlet and outlet grooves are symmetrically arranged on both sides of the light source pressure block. The outer wall of the arc-shaped grooves is symmetrically provided with insect inlet areas at equal angles. The insect inlet areas are composed of multiple through holes that are equidistantly formed. The insect inlet areas are arranged parallel to the insect inlet and outlet grooves. Two switch-on sealing members are symmetrically installed on the outer side of the insect-killing horizontal cylinder. The two switch-on sealing members are symmetrically arranged on both sides of the bottom block.

[0010] Preferably, the switch closure includes two arc-shaped baffles installed on the outer wall of the insect-killing horizontal cylinder. The arc-shaped baffles are in close contact with the outer wall of the insect-killing horizontal cylinder. An arc-shaped slider is fixedly installed on the side of the arc-shaped baffles near the insect-killing horizontal cylinder. The arc-shaped slider is slidably connected to the arc-shaped groove. Holes are equally spaced on the arc-shaped baffles, and the hollow grooves coincide with the insect-inlet area. When the arc-shaped baffles move downwards along the arc-shaped groove until the bottom ends of the two arc-shaped baffles contact each other, the two arc-shaped baffles close the insect-inlet and outlet grooves. At the same time, the hollow grooves are offset from the insect-inlet area, so that the through hole is closed. A movable adjustment component is provided between the arc-shaped baffles and the bottom block. A movable drive component is installed inside the bottom block.

[0011] Preferably, the movable adjustment component includes horizontal plates symmetrically installed on both sides of the base block. The two horizontal plates correspond to two switch closing components respectively. A guide slide is provided on the horizontal plate. The guide slide consists of two inclined slides and a connecting slide. The distance between the ends of the two inclined slides away from the base block is greater than the distance between the ends of the two inclined slides near the base block. The connecting slide is located between the ends of the two inclined slides near the base block.

[0012] Preferably, a second rotating frame is installed at the bottom of each of the two corresponding arc-shaped baffles. The structure of the second rotating frame is the same as that of the first rotating frame. A second rotating block is rotatably installed on the second rotating frame. A guide slide rod is fixedly installed at the bottom of the second rotating block. The two guide slide rods are respectively located inside the end of the two inclined slides away from the bottom block.

[0013] Preferably, the moving drive component includes symmetrically opened movable slots inside the bottom block, and a second rod slot is opened at the ends of the two movable slots that are far apart from each other. A counterweight movable block is slidably installed inside the movable slot. A crossbar is fixedly installed on the side of the counterweight movable block near the horizontal plate. The crossbar passes through the second rod slot and is fixedly connected to the horizontal plate. After the counterweight movable block moves, the center of gravity of the insect-killing horizontal cylinder shifts, thereby causing the insect-killing horizontal cylinder to rotate.

[0014] Preferably, a second spring is symmetrically installed on the side of the counterweight movable block near the horizontal plate, one end of the second spring is fixedly connected to the inner wall of the movable groove near the horizontal plate, a magnetic block is fixedly installed on the counterweight movable block, and an electromagnet is fixedly installed on the inner wall of the movable groove near the horizontal plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1) During operation, after the light source in the light source pressing block inside the insect-killing horizontal cylinder is turned on, flying insects enter the insect-killing horizontal cylinder through the through holes and the insect inlet and outlet grooves under the attraction of light. Then, the electromagnets on the left and right sides are cyclically switched on and off, which causes the counterweight movable block to move and adjust the center of gravity of the insect-killing horizontal cylinder, causing the insect-killing horizontal cylinder to deflect. This causes the light source pressing block to move and crush the flying insects on one side, thereby increasing the speed of killing flying insects.

[0017] 2) During operation, when the electromagnet on one side is energized, it attracts the magnetic block, thereby moving the counterweight block on the corresponding side to one side. This shifts the center of gravity of the insect-killing cylinder. The insect-killing cylinder is rotatably connected to the first rotating frame through the first rotating block. After the center of gravity of the insect-killing cylinder shifts, it rotates and tilts to one side, allowing the light source pressing block to slide downward under the action of gravity, crushing the flying insects on one side and facilitating the killing of flying insects.

[0018] 3) During operation, when the electromagnet on one side is energized, the horizontal plate on that side moves away from the bottom block. Meanwhile, the guide rods at the bottom of the two arc-shaped baffles on the same side are slidably installed in the two inclined slides on the horizontal plate, so that the two arc-shaped baffles move down along the arc-shaped slide until the bottom of the two arc-shaped baffles contact each other, closing the insect inlet and outlet channels and the through holes, thereby preventing flying insects from being stimulated to fly out and improving the insect control effect.

[0019] 4) During operation, the electromagnet is de-energized, causing the counterweight to move back under the force of the second spring, which in turn moves the horizontal plate back. This, in turn, pushes the two arc-shaped baffles back through the inclined slide and guide rod, opening the insect inlet and outlet slots. The dead flying insects are then discharged from the slots, allowing for automatic insect discharge and facilitating subsequent use. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] Example 1, by Figure 1-7 The present invention relates to a pest control device for greenhouses, comprising a support base 1, an insect-killing horizontal cylinder 2 above the support base 1, a bottom block 3 fixedly installed at the bottom end of the insect-killing horizontal cylinder 2, a first rotating block 4 fixedly installed at the bottom end of the bottom block 3, a first rotating frame 5 fixedly installed at the top end of the support base 1, the first rotating frame 5 including two fixed plates and a fixed shaft between the two fixed plates, the first rotating block 4 being rotatably connected to the fixed shaft, a spiral spring being installed between the first rotating block 4 and the fixed shaft, and a movable crushing assembly 6 being installed inside the insect-killing horizontal cylinder 2;

[0032] The movable crushing assembly 6 includes a light source pressing block 601 movably installed inside the insect-killing horizontal cylinder 2. The outer wall of the light source pressing block 601 contacts the inner wall of the insect-killing horizontal cylinder 2. The light source pressing block 601 consists of an outer cylindrical glass shell and an internal light source. The two ends of the insect-killing horizontal cylinder 2 are symmetrically and coaxially provided with first rod grooves 603. The two sides of the light source pressing block 601 are coaxially and fixedly installed with first side rods 602. The first side rods 602 pass through the first rod grooves 603. The ends of the first side rods 602 are fixedly installed with limit plates 604. The limit plates 604 are connected to a movable balancing component. A snap-fit ​​fixing component is installed between the first side rods 602 and the insect-killing horizontal cylinder 2. An insect-killing control assembly 7 is installed on the insect-killing horizontal cylinder 2. The movable balancing component includes a top box 606 fixedly installed at the top of the insect-killing horizontal cylinder 2. An internal block 607 is movably installed inside the top box 606. The two sides of the 607 are symmetrically fixedly installed with second side rods 608. The ends of the two second side rods 608 extend to the two ends of the top box 606 respectively. The ends of the two second side rods 608 that are far apart from each other are each installed with a longitudinal connecting plate 605. The two longitudinal connecting plates 605 are respectively fixedly connected to two limiting plates 604. The two sides of the internal block 607 are symmetrically installed with first springs 609. The ends of the first springs 609 are fixedly connected to the inner wall of the end of the top box 606. The snap-fit ​​fastener includes a positioning groove 610 opened on the first side rod 602. The positioning groove 610 is located on the outside of the insect-killing horizontal cylinder 2. The two ends of the insect-killing horizontal cylinder 2 are symmetrically installed with side plates 611. The side plates 611 are installed with screws 612. The internal threads of the screws 612 are installed with positioning bolts 613. The bottom end of the positioning bolts 613 is snapped into the interior of the positioning groove 610.

[0033] The extermination control component 7 includes arc-shaped grooves 701 symmetrically formed on the outer walls of both ends of the insect-killing horizontal cylinder 2. The cross-section of the arc-shaped grooves 701 is convex. The bottom ends of the arc-shaped grooves 701 are symmetrically provided with insect inlet and outlet grooves 703. The two insect inlet and outlet grooves 703 are symmetrically arranged on both sides of the light source pressure block 601. The outer wall of the arc-shaped grooves 701 is symmetrically provided with insect inlet areas 702 at equal angles. The insect inlet areas 702 are composed of multiple through holes that are equally spaced. The insect inlet areas 702 are arranged parallel to the insect inlet and outlet grooves 703. Two switchable closures are symmetrically installed on the outer side of the insect-killing horizontal cylinder 2. The two switchable closures are symmetrically arranged on both sides of the bottom block 3. The switchable closures include two arc-shaped baffles 704 installed on the outer wall of the insect-killing horizontal cylinder 2. The arc-shaped baffle 704 is tightly attached to the outer wall of the insect-killing horizontal cylinder 2. An arc-shaped slider 706 is fixedly installed on the side of the arc-shaped baffle 704 near the insect-killing horizontal cylinder 2. The arc-shaped slider 706 is slidably connected to the arc-shaped slide groove 701. Hollow slots 705 are equally spaced on the arc-shaped baffle 704. The hollow slots 705 coincide with the insect-entry area 702. When the arc-shaped baffle 704 moves downward along the arc-shaped slide groove 701 until the bottom ends of the two arc-shaped baffles 704 contact each other, the two arc-shaped baffles 704 close the insect-entry and insect-exit groove 703. At the same time, the hollow slots 705 are offset from the insect-entry area 702, so that the through hole is closed. A moving adjustment component 707 is provided between the arc-shaped baffle 704 and the bottom block 3. A moving drive component 708 is installed inside the bottom block 3.

[0034] The movable adjustment component 707 includes two horizontal plates 7071 symmetrically installed on both sides of the base block 3. The two horizontal plates 7071 correspond to two switch closing components respectively. A guide slide 7072 is provided on the horizontal plate 7071. The guide slide 7072 consists of two inclined slides and a connecting slide. The distance between the ends of the two inclined slides away from the base block 3 is greater than the distance between the ends of the two inclined slides close to the base block 3. The connecting slide is located between the ends of the two inclined slides close to the base block 3. The bottom ends of the corresponding two arc-shaped baffles 704 are each equipped with a second rotating frame 7073. The structure of the second rotating frame 7073 is the same as that of the first rotating frame 5. A second rotating block 7074 is rotatably installed on the second rotating frame 7073. A guide slide rod 7075 is fixedly installed at the bottom end of the second rotating block 7074. The two guide slide rods 7075 are located inside the ends of the two inclined slides away from the base block 3 respectively.

[0035] The moving drive component 708 includes symmetrically formed movable slots 7081 inside the base block 3. Each of the two movable slots 7081 has a second rod slot 7082 at one end that is far from each other. A counterweight movable block 7083 is slidably installed inside the movable slot 7081. A crossbar 7084 is fixedly installed on the side of the counterweight movable block 7083 near the horizontal plate 7071. The crossbar 7084 passes through the second rod slot 7082 and is fixedly connected to the horizontal plate 7071. When the counterweight movable block 7083 moves, it shifts the center of gravity of the insect-killing horizontal cylinder 2, thereby causing the insect-killing horizontal cylinder 2 to rotate. A second spring 7085 is symmetrically installed on one side of the horizontal plate 7071. One end of the second spring 7085 is fixedly connected to the inner wall of the movable groove 7081 near the horizontal plate 7071. A magnet 7086 is fixedly installed on the counterweight movable block 7083. Electromagnets 7087 are fixedly installed on the inner wall of the movable groove 7081 near the horizontal plate 7071. After the light source in the light source pressure block 601 inside the insect-killing horizontal cylinder 2 is turned on, flying insects enter the insect-killing horizontal cylinder 2 through the through hole and the insect inlet / outlet groove 703 under phototaxis, and then pass through the electromagnets on the left and right sides. The cyclic switching of power on and off of electromagnet 7087 causes the movable counterweight block 7083 to move, adjusting the center of gravity of the insect-killing cylinder 2. This causes the cylinder 2 to deflect, moving the light source pressing block 601 to crush flying insects on one side, increasing the insect-killing speed. When electromagnet 7087 on one side is energized, it attracts magnetic block 7086, causing the corresponding movable counterweight block 7083 to move to one side, thus shifting the center of gravity of the insect-killing cylinder 2. The insect-killing cylinder 2 is rotatably connected to the first rotating frame 5 via the first rotating block 4, causing the center of gravity of the insect-killing cylinder 2 to shift towards one side. The side rotation and tilting allow the light source pressure block 601 to slide downwards under the action of gravity, crushing the flying insects on one side and facilitating their extermination. At the same time, the horizontal plate 7071 on one side moves away from the bottom block 3, while the guide rods 7075 at the bottom of the two arc-shaped baffles 704 on the same side are slidably installed in the two inclined slides on the horizontal plate 7071. This allows the two arc-shaped baffles 704 to move downwards along the arc-shaped slide grooves 701 until the bottom ends of the two arc-shaped baffles 704 contact each other, closing the insect inlet and outlet grooves 703 and the through holes, thereby preventing the flying insects from being startled and flying out, and improving the insect extermination effect.

[0036] Working principle: During operation, the positioning bolts 613 at both ends of the insect-killing horizontal cylinder 2 are turned to disengage the positioning bolts 613 from the positioning grooves 610. The controller controls the electromagnets 7087 in the two movable grooves 7081 to intermittently switch on and off power.

[0037] In the initial state, the slot 705 on the arc-shaped baffle 704 corresponds to the insect inlet area 702, and the insect inlet and outlet channel 703 is in the open state. The light source in the light source pressure block 601 is powered on. Since flying insects are phototactic, they enter the light source pressure block 601 inside the insect-killing horizontal cylinder 2 through the through hole in the insect inlet area 702 and the insect inlet and outlet channel 703.

[0038] When the electromagnet 7087 in the left movable slot 7081 is energized, it attracts the magnetic block 7086, causing the counterweight movable block 7083 in the left movable slot 7081 to move outward. After moving, the center of gravity of the insect-killing horizontal cylinder 2 shifts to the left. Since the insect-killing horizontal cylinder 2 is rotatably connected to the first rotating frame 5 through the first rotating block 4, the left end of the insect-killing horizontal cylinder 2 rotates downward and tilts. During this process, the movement of the counterweight movable block 7083 drives the horizontal plate 7071 to move, while the bottom ends of the two arc-shaped baffles 704 on the same side... The guide slide rod 7075 is located in the two inclined slides of the guide slide 7072. During the movement of the horizontal plate 7071, the two guide slide rods 7075 move closer and closer along the two inclined slides, thereby driving the two arc-shaped baffles 704 to move downward along the arc-shaped slide groove 701, so that the bottom ends of the two arc-shaped baffles 704 approach each other until they contact each other. At the same time, the empty groove 705 on the arc-shaped baffle 704 is offset from the insect inlet area 702, blocking the through hole, so that the flying insects inside the insect-killing horizontal cylinder 2 located to the left of the light source pressure block 601 are sealed.

[0039] As the insect-killing cylinder 2 is tilted, the light source pressing block 601 slides downward under the action of gravity, causing the light source pressing block 601 to crush and kill the flying insects inside the insect-killing cylinder 2 on the left side of the light source pressing block 601. At the same time, the space on the right side of the light source pressing block 601 is increased, making it easier for more flying insects to enter the insect-killing cylinder 2 for treatment, thus improving the insect-killing efficiency.

[0040] Subsequently, the electromagnet 7087 in the left movable slot 7081 is de-energized, causing the counterweight movable block 7083 to move back under the elastic force of the second spring 7085, thereby driving the horizontal plate 7071 to move back. This, in turn, pushes the two arc-shaped baffles 704 back through the inclined slide and guide slide rod 7075, opening the insect inlet and outlet slot 703. At this time, the dead flying insects are discharged from the insect inlet and outlet slot 703, achieving automatic insect discharge for convenient subsequent use.

[0041] After the counterweight movable block 7083 moves back, the center of gravity of the insect-killing horizontal cylinder 2 shifts slightly to the right. At this time, the light source pressing block 601 moves back under the elastic force of the first spring 609 until the light source pressing block 601 moves back to the center of gravity position. At this time, the insect-killing horizontal cylinder 2 rotates to a horizontal state under the elastic force of the spiral spring between the first rotating block 4 and the first rotating frame 5. Then, the electromagnet 7087 in the right movable slot 7081 is energized, which causes the insect-killing horizontal cylinder 2 to rotate and tilt to the right. The light source pressing block 601 moves to the right to kill insects. The insect-killing horizontal cylinder 2 is killed by rotating back and forth left and right.
