Description

Technical Field

[0001] This utility model belongs to the field of pest and disease control technology, and in particular relates to a field pest and disease control box for grain crops. Background Technology

[0002] In the process of growing grain crops, the prevention and control of diseases and pests is a key link to ensure crop yield and quality. At present, the main methods of disease and pest control in the field are manual spraying of pesticides or single trapping devices. Manual spraying of pesticides is not only inefficient, but also pesticides can easily cause harm to the human body and may also lead to excessive pesticide residues. Single trapping devices can only target some pests, and the control effect is limited.

[0003] A search revealed that patent document CN222109026U discloses a field pest and disease control box for grain crops. The box includes a control box with an insect-trapping and killing device inside. The control box comprises a box body with an internal cavity for accommodating the insect-trapping and killing device. The cavity has openings at its upper end and front. This device traps and kills insects; after being killed, the insects fall into a drawer below the device for easy cleaning. The control box has a simple structure and is easy to operate.

[0004] However, the above-mentioned equipment still has the following technical problems during use: Relying solely on a single trapping mechanism is insufficient to address diverse types of pests and diseases, and it is difficult to guarantee sustained and efficient control effects in complex field environments. Utility Model Content

[0005] The purpose of this invention is to address the problems mentioned in the background art by providing a field pest and disease control box for grain crops that offers multiple control methods, a high degree of automation, and good control effects.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A field pest and disease control box for grain crops includes a base, a box body fixedly installed on the upper surface of the base, a U-shaped support frame fixedly installed on the inner bottom wall of the box body, a drive motor fixedly installed on the lower surface of the U-shaped support frame, a rotating rod fixedly installed on the output shaft of the drive motor through a coupling, and a trapping cam and a spraying cam fixedly installed on the rod body from top to bottom, with a phase difference of 180° between the trapping cam and the spraying cam. A connecting rod is fixedly installed on the inner wall of the box. A piston tube is fixedly installed at one end of the connecting rod. A piston head is slidably connected inside the piston tube. A round rod is fixedly installed on the side wall of the piston head. A vertical plate is fixedly installed on the inner wall of the box. The round rod passes through the vertical plate inside the box and is slidably connected to the vertical plate. A baffle is fixedly installed at the other end of the round rod. A spring is fixedly connected between the baffle and the vertical plate. The spring is sleeved around the circumference of the round rod. The outer wall of the spraying cam abuts against the side wall of the baffle. A trapping mechanism is fixedly installed on the outer wall of the box.

[0007] Preferably, the trapping mechanism includes a support plate fixedly installed on the outer wall of the box, a lampshade fixedly installed on the lower surface of the support plate, an insect inlet distributed in a circular array on the outer wall of the lampshade, a trapping lamp fixedly installed on the inner wall of the lampshade, a trapping box fixedly installed on the lower surface of the lampshade, an openable insect-clearing opening on the side wall of the trapping box, and a fan installed at the connection between the trapping box and the lampshade, the fan being arranged opposite to the trapping lamp.

[0008] Preferably, an arc-shaped conductive sheet is fixedly installed on the side wall of the upright plate by a fixing plate, and a conductive contact block is fixedly installed on the outer wall of the trapping cam. The arc-shaped conductive sheet and the conductive contact block are in intermittent contact, and the arc-shaped conductive sheet and the conductive contact block are electrically connected to the fan.

[0009] Preferably, a medicine box is fixedly installed on the inner bottom wall of the box, an inlet pipe is fixedly connected between the medicine box and the piston tube, an outlet pipe is fixedly connected between the trap box and the piston tube, a one-way valve is provided inside the inlet pipe and the outlet pipe, and a nozzle is fixedly installed at one end of the outlet pipe located inside the trap box.

[0010] Preferably, a solar panel is fixedly installed on the top of the box, and a battery is provided inside the box. The solar panel is electrically connected to the battery, and the battery supplies power to the drive motor, the trapping light, and the fan. A controller is fixedly installed on the box, and the controller is electrically connected to the drive motor, the trapping light, and the fan.

[0011] Preferably, the lower surface of the housing is fixedly equipped with casters, and the side wall of the housing is provided with an openable maintenance door.

[0012] Compared with existing technologies, the advantages of this field pest and disease control kit for grain crops are: 1. This utility model uses two methods: physical trapping and chemical extermination. Physical trapping uses a trapping lamp to attract phototactic pests, and a fan creates negative pressure to suck them into the trapping box. Chemical extermination uses a piston-type sprayer to precisely apply pesticides to the pests in the trapping box. This method can simultaneously address multiple types of pests that are phototactic, photophobic, or sensitive to chemical agents, effectively expanding the scope of pest control.

[0013] 2. This utility model achieves an alternating mode of "stopping spraying when trapping and stopping trapping when spraying" by setting a phase difference between the trapping cam and the spraying cam. During the trapping stage, the fan is turned on to prevent pesticide droplets from adhering to the surface of the trapping lamp and affecting the trapping effect; during the spraying stage, the fan is turned off to ensure that the pesticide forms a closed space inside the trapping box, prolonging the contact time with pests, improving the killing rate, and reducing energy waste.

[0016] The following embodiments are for illustrative purposes only and are not intended to limit the scope of this invention.

[0017] Example: Refer to Figures 1 to 4 A field pest and disease control box for grain crops includes a base 1, a box body 2 fixedly installed on the upper surface of the base 1, a U-shaped support frame 3 fixedly installed on the inner bottom wall of the box body 2, a drive motor 4 fixedly installed on the lower surface of the U-shaped support frame 3, a rotating rod 5 fixedly installed on the output shaft of the drive motor 4 through a coupling, and a trapping cam 6 and a spraying cam 7 fixedly installed on the rod body of the rotating rod 5 from top to bottom, with a phase difference of 180° between the trapping cam 6 and the spraying cam 7. A connecting rod 8 is fixedly installed on the inner wall of the box 2. A piston tube 9 is fixedly installed on one end of the connecting rod 8. A piston head 10 is slidably connected inside the piston tube 9. A round rod 11 is fixedly installed on the side wall of the piston head 10. A vertical plate 12 is fixedly installed on the inner wall of the box 2. The round rod 11 passes through the vertical plate 12 inside the box 2 and is slidably connected to the vertical plate 12. A baffle 13 is fixedly installed on the other end of the round rod 11. A spring 14 is fixedly connected between the baffle 13 and the vertical plate 12. The spring 14 is sleeved around the round rod 11. The outer wall of the spraying cam 7 abuts against the side wall of the baffle 13. A trapping mechanism is fixedly installed on the outer wall of the box 2.

[0018] Specifically, the trapping mechanism includes a support plate 15 fixedly installed on the outer wall of the box 2. A lampshade 16 is fixedly installed on the lower surface of the support plate 15. The lampshade 16 is made of transparent polycarbonate material, and the inner wall is sprayed with an anti-fog coating to prevent field moisture from condensing on the surface and affecting light transmission. The outer wall of the lampshade 16 has insect inlets 17 arranged in a circular array. A trapping lamp 18 is fixedly installed on the inner wall of the lampshade 16. The trapping lamp 18 is an ultraviolet lamp with a wavelength of 365nm. A trapping box 19 is fixedly installed on the lower surface of the lampshade 16 to collect the sucked-in pests and provide a closed space for spraying pesticides. The side wall of the trapping box 19 has an openable insect removal port equipped with a transparent acrylic observation window to visually observe the amount of insects accumulated. The insect removal port cover is fixed by a buckle. A fan is installed at the connection between the trapping box 19 and the lampshade 16. The fan is positioned opposite to the trapping lamp 18.

[0019] Specifically, an arc-shaped conductive sheet 20 is fixedly installed on the side wall of the upright plate 12 by a fixing plate, and a conductive contact block 21 is fixedly installed on the outer wall of the trapping cam 6. The arc-shaped conductive sheet 20 and the conductive contact block 21 are in intermittent contact, and the arc-shaped conductive sheet 20 and the conductive contact block 21 are electrically connected to the fan.

[0020] Specifically, a medicine tank 22 is fixedly installed on the inner bottom wall of the box 2. A medicine inlet pipe 23 is fixedly connected between the medicine tank 22 and the piston tube 9. A medicine outlet pipe 24 is fixedly connected between the trap box 19 and the piston tube 9. Both the medicine inlet pipe 23 and the medicine outlet pipe 24 are equipped with one-way valves. Both are spring-loaded one-way valves to prevent the backflow of medicine from causing pipe blockage. The one-way valve of the medicine inlet pipe 23 only allows the medicine to flow from the medicine tank 22 to the piston tube 9, and the one-way valve of the medicine outlet pipe 24 only allows the medicine to flow from the piston tube 9 to the trap box 19. A nozzle 25 is fixedly installed at one end of the medicine outlet pipe 24 inside the trap box 19 to atomize the medicine and spray it out, increasing the contact area between the medicine and the pests and improving the killing effect.

[0021] Specifically, a solar panel is fixedly installed on the top of the box 2, and a battery is installed inside the box 2. The solar panel is electrically connected to the battery, and the battery supplies power to the drive motor 4, the trapping light 18, and the fan. A controller is fixedly installed on the box 2, and the controller is electrically connected to the drive motor 4, the trapping light 18, and the fan.

[0022] Specifically, the lower surface of the box 2 is fixedly equipped with casters 26, which are polyurethane casters with brakes, allowing for smooth movement on muddy field roads. The side wall of the box 2 is provided with an openable maintenance door, which adopts a magnetic sealing structure and is fitted with rubber sealing strips on the edges to prevent rainwater from seeping into the box 2 and damaging electrical components.

[0023] The functional principle of this utility model can be explained through the following operation methods: 1. In use, start the drive motor 4, and its output shaft drives the rotating rod 5 to rotate through the coupling. The trapping cam 6 and the spraying cam 7 on the rotating rod 5 rotate synchronously. Since the phase difference between the two is 180°, the alternating action of "the spraying mechanism stopping when the trapping mechanism is working, and the trapping mechanism stopping when the spraying mechanism is working" can be realized. When the protruding part of the spraying cam 7 rotates to contact the baffle 13, it pushes the baffle 13 to move towards the upright plate 12. The baffle 13 drives the round rod 11 and the piston head 10 to slide along the piston tube 9 (the space inside the piston tube 9 is compressed). The spring 14 is compressed. At this time, the liquid medicine in the piston tube 9 is pressed into the trap box 19 through the medicine outlet pipe 24. It forms a spray through the atomizing nozzle 25 to kill the pests already captured in the trap box 19. When the protruding part of the spraying cam 7 leaves the baffle 13, the spring 14 returns to its original position (the elasticity drives the baffle 13 to move in the opposite direction). It drives the round rod 11 and the piston head 10 to slide in the opposite direction along the piston tube 9 (a negative pressure is formed inside the piston tube 9). At this time, the liquid medicine in the medicine tank 22 is sucked into the piston tube 9 through the medicine inlet pipe 23, completing one "suction-spraying" cycle.

[0024] 2. The trapping mechanism operates as follows: After the trapping lamp 18 is turned on, it releases attracting light through the insect inlets 17 arranged in a circular array on the lampshade 16, attracting pests to approach. When the trapping cam 6 rotates, the conductive contact 21 on its outer wall intermittently contacts the arc-shaped conductive sheet 20: when in contact, the circuit is open, the fan starts, and negative pressure is generated to draw pests from the insect inlets 17 into the lampshade 16, and then the fan pressure sends them into the trapping box 19; when the contact is broken, the fan stops, reducing energy consumption. The pests collected in the trapping box 19 can be periodically cleaned through the openable insect cleaning port to avoid accumulation that affects the effectiveness.
