Description

Technical Field

[0001] The present invention belongs to the technical field of pest control, and particularly relates to an ultrasonic pest repellent system combining air and ground. Background Art

[0002] Ultrasonic pest repellent works by an ultrasonic emitter emitting high-frequency sound waves beyond the audible range of humans, stimulating the auditory systems of pests such as rodents and insects, forcing them to flee the area where the ultrasonic pest repellent is operating. In physical pest control, the coverage radius of a single ground ultrasonic device is usually less than 15 meters, making it difficult to cope with the cross-regional spread of migratory pests (such as rice planthoppers).

[0003] The Chinese invention patent with the publication number "CN112088869A" discloses "an ultrasonic pest repellent device for unmanned aerial vehicles and its usage method". When this invention is in use, during the pest repellent operation of the pest repellent unmanned aerial vehicle, it drives insects away towards the insect-catching device, and in cooperation with the volatile inducing hormone and the capture fiber clusters arranged in the insect-catching device, firmly fixes the insects in the insect-catching device, facilitating subsequent unified recovery and treatment, and achieving a relatively thorough repelling of pests. However, when the unmanned aerial vehicle drives the ultrasonic waves to repel pests in the crop planting area, it is necessary to operate the unmanned aerial vehicle to drive the ultrasonic waves for pest repelling. Since the battery power of the unmanned aerial vehicle is limited and the duration of a single use is fixed, the endurance of the unmanned aerial vehicle will not meet the requirements when performing ultrasonic pest repellent for a long time.

The hose inside the installation box sequentially passes through the second guide tube and the first guide tube and then is connected to the balloon.

[0016] As described above, an air-ground combined ultrasonic insect repellent system of the present invention has at least the following beneficial effects: 1. When the present invention needs to repel insects from crops, the balloon can be filled with a gas having a density lower than that of air through an air pump, so that the balloon drives the ultrasonic transmitter to fly into the air. The ultrasonic transmitter can be turned on to repel insects from the crops downward. The ultrasonic transmitter only needs to be driven by the buoyancy of the balloon to fly into the air, so that the ultrasonic transmitter can be ensured to repel insects from crops at a high altitude for a long time.

[0017] 2. When the hose of the present invention is retracted into the installation box, first, the air pump pumps back and compresses the gas with a density lower than that of air in the hose into the gas storage cylinder. Then, as the rope winds around the rotating shaft under the rotation of the rotating shaft, when pulling the balloon to descend, the first rotational power source rotates forward to drive the first rotating column to wind the hose at the same speed as the balloon descends, so that the hose winds from between the roller and the second rotating column onto the first rotating column. When the balloon stops descending after reaching the designated position, the first telescopic power source retracts, causing the roller to press the hose against the second rotating column after squeezing the hose. Then, the first rotational power source rotates in reverse. At this time, the second rotational power source drives the second rotating column to rotate out the hose released by the reverse rotation of the first rotating column from between the roller and the second rotating column to the first rotating column. After the rotation is completed, the first telescopic power source extends, causing the roller to stop pressing the hose. The air pump pumps back and compresses the gas with a density lower than that of air in both the balloon and the hose into the gas storage cylinder, enabling the roller to press the hose against the second rotating column after squeezing the hose when it is necessary to rotate out the hose wound on the first rotating column from the first rotating column, and when it is necessary to pump out the gas with a density lower than that of air in the balloon and the hose, the roller leaves the state of pressing the hose under the action of the first telescopic power source, facilitating the air pump to pump out the gas with a density lower than that of air in the balloon and the hose. The structural design is ingenious.

[0018] 3. Driven by the balloon, the present invention uses an ultrasonic emitter in the air to drive away pests from the crops on the ground, and uses an insecticidal lamp on the ground to drive away pests from the crops below and around the guide plate. Thus, the crops on the land are driven away from pests by combining the ultrasonic emitter and the insecticidal lamp. Moreover, the pests in the areas (the crops below and around the guide plate) that cannot be covered by the ultrasonic waves emitted by the ultrasonic emitter can be driven away by the insecticidal lamp. The cooperation between the insecticidal lamp and the ultrasonic emitter is ingenious.

[0019] 4. When the balloon retracts into the accommodation box, the guide plate of the present invention can wrap the mounting rack under the action of the second telescopic power source, thereby guiding the retracted mounting rack to accurately retract into the accommodation box. Moreover, after retraction, the insecticidal lamp is located on the side wall of the guide plate away from the mounting rack, enabling the insecticidal lamp to continue to be turned on to drive away pests around the accommodation box after retraction. The structural design is ingenious. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In this embodiment, the gas control unit and the retractable unit are installed in the middle of the crops on a piece of land. When it is necessary to use the ultrasonic emitter 101 to drive away pests from the crops, the air pump 202 fills the balloon 103 with a gas whose density is lower than that of air. Then, the balloon 103 drives the ultrasonic emitter 101 to fly into the air. The ultrasonic emitter 101 is turned on to drive away pests downward from the crops. After the pest control is completed, the rope 302 is wound around the rotating shaft 303 under the rotation of the rotating shaft 303. During the winding process of the rope 302, the mounting frame 102 is pulled into the receiving box 301, and the mounting frame 102 drives the balloon 103 to move together, thereby reducing the height of the balloon 103.

[0027] In the present invention, when it is necessary to drive away pests from the crops, the air pump 202 can fill the balloon 103 with a gas whose density is lower than that of air, so that the balloon 103 drives the ultrasonic emitter 101 to fly into the air.

The ultrasonic emitter 101 only needs to be driven by the balloon 103 to fly into the air, so that the ultrasonic emitter 101 can be ensured to drive away pests from the crops at a high altitude for a long time.

[0028] Please refer to Figure 1 and Figure 3 , the gas control unit further includes a mounting box 203, a gas storage cylinder 204, a solenoid valve 205 and a rigid pipe 206; The mounting box 203 is installed below the ground. The air pump 202 and the gas storage cylinder 204 are both fixedly installed in the mounting box 203. The gas delivery end of the gas storage cylinder 204 is communicated with the air intake end of the air pump 202, and the air intake end of the gas storage cylinder 204 is communicated with the gas delivery end of the air pump 202. The gas charging and discharging end of the air pump 202 is connected to one end of the solenoid valve 205. The other end of the solenoid valve 205 is communicated with one end of the rigid pipe 206. The other end of the rigid pipe 206 is communicated with the flexible pipe 201. The flexible pipe 201 penetrates through the mounting box 203 and is communicated with the balloon 103.

[0029] In this embodiment, when filling the balloon 103 with gas, the solenoid valve 205 is opened, and the air pump 202 sequentially pumps the compressed gas with a density lower than that of air in the gas storage cylinder 204 into the gas delivery end of the gas storage cylinder 204, the gas charging and discharging end of the air pump 202, the solenoid valve 205, the rigid pipe 206 and the flexible pipe 201 and then into the balloon 103. When the balloon 103 is filled with the gas with a density lower than that of air, the solenoid valve 205 is closed; When pumping the gas out of the balloon 103, the solenoid valve 205 is opened, and the air pump 202 sequentially pumps the gas with a density lower than that of air in the balloon 103 into the flexible pipe 201, the rigid pipe 206, the solenoid valve 205, the gas charging and discharging end of the air pump 202 and the air intake end of the gas storage cylinder 204 and then recompresses it in the gas storage cylinder 204. When the gas with a density lower than that of air in the balloon 103 is pumped out, the solenoid valve 205 is closed.

[0030] When the present invention inflates the balloon 103, the air pump 202 can draw the gas with a density lower than that of air compressed in the gas storage cylinder 204 into the balloon 103. When the gas in the balloon 103 is pumped out, the air pump 202 can recompress the gas with a density lower than that of air in the balloon 103 into the gas storage cylinder 204, so that the gas with a density lower than that of air in the present invention can be recycled.

[0031] Please refer to Figure 1 、 Figure 3 and Figure 4 The gas control unit further includes a first rotating column 207, a rotating joint 208, a first channel 209 and a second channel 210; The first rotating column 207 is rotatably installed in the installation box 203. The rotation axis of the first rotating column 207 is parallel to the horizontal plane. A first channel 209 and a second channel 210 are opened in the first rotating column 207. The axial extension line of the first channel 209 coincides with the rotation axis of the first rotating column 207; One end of the first channel 209 penetrates the end face of the first rotating column 207 close to the air pump 202. The hard pipe 206 is connected to one end of the first channel 209 through the rotating joint 208. The other end of the first channel 209 is communicated with one end of the second channel 210. The other end of the second channel 210 penetrates the side wall of the first rotating column 207 and is communicated with the flexible pipe 201.

[0032] In this embodiment, when inflating the balloon 103, the solenoid valve 205 is opened, and the air pump 202 draws the gas with a density lower than that of air compressed in the gas storage cylinder 204 into the balloon 103 in sequence through the gas delivery end of the gas storage cylinder 204, the air charging and discharging end of the air pump 202, the solenoid valve 205, the hard pipe 206, the first channel 209, the second channel 210 and the flexible pipe 201. When the balloon 103 is filled with the gas with a density lower than that of air, the solenoid valve 205 is closed; When pumping out the gas in the balloon 103, the solenoid valve 205 is opened, and the air pump 202 pumps the gas with a density lower than that of air in the balloon 103 into the gas storage cylinder 204 in sequence through the flexible pipe 201, the second channel 210, the first channel 209, the hard pipe 206, the solenoid valve 205, the air charging and discharging end of the air pump 202 and the air inlet end of the gas storage cylinder 204 and recompresses it in the gas storage cylinder 204. When the gas with a density lower than that of air in the balloon 103 is pumped out, the solenoid valve 205 is closed.

[0033] When the first rotating column 207 rotates in the present invention, the rotating joint 208 rotates around the rigid tube 206 together with the first rotating column 207, while the rigid tube 206 remains stationary. Thus, when the balloon 103 is subsequently retracted, the rope 302 is wound around the rotating shaft 303 under the rotation of the rotating shaft 303, thereby lowering the height of the balloon 103 through the rope 302. The first rotating column 207 rotates to wind the flexible tube 201 to temporarily collect the flexible tube 201 into the installation box 203. At this time, the rigid tube 206 and the flexible tube 201 still remain in a connected state, and the structural design is ingenious.

[0035] In this embodiment, when the balloon 103 is retracted after the ultrasonic emitter 101 completes pest control, the rope 302 is wound around the rotating shaft 303 under the rotation of the rotating shaft 303, thereby lowering the height of the balloon 103 through the rope 302. The first rotating power source 211 drives the second gear 213 to rotate at the same speed as the descent of the balloon 103. The second gear 213 drives the first gear 212 to rotate, and the first gear 212 drives the first rotating column 207 to rotate together. The first rotating column 207 rotates to wind the flexible tube 201 to temporarily collect the flexible tube 201 into the installation box 203.

[0036] The first rotating power source 211 of the present invention can wind the flexible tube 201 at the same speed as the descent of the balloon 103 when the balloon 103 descends, so as to vertically retract the flexible tube 201 above the ground after the balloon 103 descends into the installation box 203, thereby avoiding the problem that the flexible tube 201 is caught by the crops above the ground.

A first sliding groove 219 is formed in the installation box 203.

[0038] In this embodiment, when the balloon 103 is filled with gas, the solenoid valve 205 is opened, and the air pump 202 sequentially pumps the gas with a density lower than that of air compressed in the gas storage cylinder 204 into the gas delivery end of the gas storage cylinder 204, the air charging and discharging end of the air pump 202, the solenoid valve 205, the rigid tube 206, the first channel 209, the second channel 210, and the flexible tube 201, and then into the balloon 103. When the balloon 103 is filled with the gas with a density lower than that of air, the solenoid valve 205 is closed, and the balloon 103 drives the flexible tube 201 in the mounting box 203 to rise together. Then, the ultrasonic transmitter 101 is turned on to drive insects away from the crops downward. After the insect repelling is completed, the solenoid valve 205 is opened, and the air pump 202 pumps the gas with a density lower than that of air in the flexible tube 201 into the second channel 210, the first channel 209, the rigid tube 206, the solenoid valve 205, the air charging and discharging end of the air pump 202, and the air inlet end of the gas storage cylinder 204 in sequence, and then recompresses it in the gas storage cylinder 204. The solenoid valve 205 is closed, and then the rope 302 is wound around the rotating shaft 303 under the rotation of the rotating shaft 303, so as to lower the height of the balloon 103 through the rope 302. While the balloon 103 is descending, the first rotary power source 211 rotates forward to drive the first rotary column 207 to wind the flexible tube 201 at the same speed as the balloon 103 descends, so that the flexible tube 201 is transferred from between the roller 221 and the second rotary column 214 onto the first rotary column 207. When the balloon 103 stops descending after descending to the designated position, the first telescopic power source 217 retracts, so that the roller 221 presses the flexible tube 201 and then presses it against the second rotary column 214. Then, the first rotary power source 211 rotates in reverse. At this time, the second rotary power source 215 drives the second rotating column to transfer the flexible tube 201 released by the first rotary column 207 from between the roller 221 and the second rotary column 214 out of the first rotary column 207. After the transfer is completed, the first telescopic power source 217 extends, so that the roller 221 no longer presses the flexible tube 201. The air pump 202 pumps the gas with a density lower than that of air in the balloon 103 and the flexible tube 201 into the flexible tube 201, the second channel 210, the first channel 209, the rigid tube 206, the solenoid valve 205, the air charging and discharging end of the air pump 202, and the air inlet end of the gas storage cylinder 204 in sequence, and then recompresses it in the gas storage cylinder 204. When the gas with a density lower than that of air in the balloon 103 is pumped out, the solenoid valve 205 is closed, waiting for the next insect repelling operation.

[0039] Under the action of the first telescopic power source 217, the roller 221 of the present invention can press the flexible tube 201 against the second rotary column 214 after squeezing it when the flexible tube 201 wound on the first rotary column 207 needs to be transferred out of the first rotary column 207. When the balloon 103 and the flexible tube 201 need to pump out the gas with a density lower than that of air, the roller 221 leaves the state of pressing the flexible tube 201 under the action of the first telescopic power source 217, which is convenient for the air pump 202 to pump out the gas with a density lower than that of air in the balloon 103 and the flexible tube 201. The structural design is ingenious.

[0040] Please refer toFigure 6 and Figure 7 , the retracting and extending unit further includes a second telescopic power source 401, a telescopic frame 402, a second sliding groove 403, an elastic hinge 404, a guide plate 405, and an insect repellent lamp 406; The second telescopic power source 401 is not limited herein. Its function is to provide telescopic power, which can be a cylinder, a hydraulic cylinder, etc.; The fixed end of the second telescopic power source 401 is fixedly connected inside the accommodation box 301. The telescopic direction of the second telescopic power source 401 is vertically arranged. The extending end of the second telescopic power source 401 is fixedly connected to the telescopic frame 402. A second sliding groove 403 is vertically formed inside the accommodation box 301. The telescopic frame 402 moves along the sliding guide direction of the second sliding groove 403 under the action of the second telescopic power source 401; One end of an elastic hinge 404 is fixedly connected to the upper end of each inner side wall of the telescopic frame 402. The other end of each elastic hinge 404 is fixedly connected to a guide plate 405. When the telescopic frame 402 extends out of the accommodation box 301 under the action of the second telescopic power source 401, the guide plates 405 can rotate from the vertical state to the horizontal state towards the outer side wall of the telescopic frame 402 under the action of the elastic hinges 404; An insect repellent lamp 406 is fixedly connected to each guide plate 405. When the guide plate 405 rotates to the horizontal state, the insect repellent lamp 406 is located below the guide plate 405.

[0041] In this embodiment, when it is necessary to repel insects from crops through the ultrasonic transmitter 101, first extend the second telescopic power source 401. The second telescopic power source 401 pushes the telescopic frame 402 to rise. When the telescopic frame 402 rises to the point where the guide plates 405 start to open, the air pump 202 fills the balloon 103 with a gas having a density lower than that of air. After being filled, the rotating shaft 303 rotates to release the rope 302 wound around the rotating shaft 303. The rope 302 drives the balloon 103 to rise. After rising, the second telescopic power source 401 continues to extend. After extending, the guide plates 405 rotate from the vertical state to the horizontal state towards the outer side wall of the telescopic frame 402 under the action of the elastic hinges 404. Then the balloon 103 continues to rise. After rising to the specified height, the rotating shaft 303 stops rotating, so as to park the balloon 103 at the specified height. Then turn on the insect repellent lamp 406 and the ultrasonic transmitter 101. The insect repellent lamp 406 on the ground repels insects from the crops below and around the guide plate 405, and the ultrasonic transmitter 101 repels insects from the crops on the ground.

[0042] The present invention repels pests on crops on the ground through an ultrasonic transmitter 101 in the air, and repels pests on the crops below and around the guide plate 405 on the ground through a pest repellent lamp 406. Thus, the crops on the land are repelled in a combined manner of air and ground. And the places where the ultrasonic waves emitted by the ultrasonic transmitter 101 cannot cover (the crops around the lower part of the guide plate 405) can be repelled by the pest repellent lamp 406, making the pest repellent range of the present invention more comprehensive.

[0043] Please refer to Figure 1 、 Figure 7 、 Figure 8 and Figure 9 and, the retracting and extending unit further includes a first bevel gear set 304, a third rotary power source 305, a pressure sensor 306, a third guide tube 307 and a fourth guide tube 308; No limitation is imposed on the third rotary power source 305 herein. Its function is to provide rotary power and it can be an AC motor, a stepper motor, etc.; The rotating shaft 303 is rotatably installed in the telescopic frame 402, and the rotation axis of the rotating shaft 303 is horizontally arranged; The fixed end of the third rotary power source 305 is fixedly installed on the telescopic frame 402. The rotating end of the third rotary power source 305 is fixedly connected to one end of the first bevel gear set 304, and the other end of the first bevel gear set 304 is fixedly connected to the rotating shaft 303; Both the third guide tube 307 and the fourth guide tube 308 are fixedly connected to the telescopic frame 402. The third guide tube 307 is located below the fourth guide tube 308. The guide axes of the fourth guide tube 308 and the third guide tube 307 are vertically arranged, and the guide axis of the fourth guide tube 308 is consistent with the guide axis of the third guide tube 307. The fourth guide tube 308 is a rectangular column. A pressure sensor 306 is installed on each of the four side walls of the fourth guide tube 308. Through holes are formed on the four side walls of the fourth guide tube 308, and the pressure sensor 306 is inserted into the through hole and surrounds the inner wall of the fourth guide tube 308; One end of the rope 302 is fixedly connected to one end of the mounting frame 102 in the length direction. The other end of the rope 302 passes through the fourth guide tube 308 and the third guide tube 307 and is fixedly connected to the rotating shaft 303; In this embodiment, two retracting and extending units are provided. The two retracting and extending units are arranged on both sides of the mounting frame 102 in the length direction, and the joints of the two ropes 302 and the mounting frame 102 are centrosymmetric about the center of the ultrasonic transmitter 101.

[0044] In this embodiment, when it is necessary to drive away pests from crops through the ultrasonic transmitter 101, first extend the second telescopic power source 401. The second telescopic power source 401 pushes the telescopic frame 402 to rise. When the telescopic frame 402 rises to the point where the guide plate 405 begins to open, the air pump 202 fills the balloon 103 with a gas having a density lower than that of air. After it is full, the two third rotary power sources 305 drive the corresponding rotating shafts 303 to rotate at the same speed, so that the rotating shafts 303 unwind the ropes 302 wound around the rotating shafts 303. The ropes 302 drive the balloon 103 to rise. After rising, the second telescopic power source 401 continues to extend. After extension, the guide plate 405 rotates from the vertical state to the horizontal state along the outer side wall of the telescopic frame 402 under the action of the elastic hinge 404. Then the balloon 103 continues to rise. After rising to the designated height, the two third rotary power sources 305 stop rotating, so that the rotating shafts 303 stop rotating, thereby parking the balloon 103 at the designated height. Then turn on the pest control lamp 406 and the ultrasonic transmitter 101. The pest control lamp 406 on the ground drives away pests from the crops below and around the guide plate 405, and the ultrasonic transmitter 101 drives away pests from the crops on the ground. When the pressure sensor 306 detects that the pressure of the fourth guide tube 308 by the rope 302 is greater than the set threshold value, the two third rotary power sources 305 drive the corresponding rotating shafts 303 to rotate at the same speed, so that the rotating shafts 303 rewind the ropes 302 around the rotating shafts 303. During this process, the balloon 103 and the mounting frame 102 will slowly descend. During the descending process, the second telescopic power source 401 retracts, and the second telescopic power source 401 pushes the telescopic frame 402 to descend. After extension, the guide plate 405 rotates from the horizontal state back to the vertical state under the action of the elastic hinge 404. Finally, the guide plate 405 wraps the descending mounting frame 102, thereby receiving the mounting frame 102 into the receiving box 301.

[0045] The guide plate 405 of the present invention can wrap the mounting frame 102 under the action of the second telescopic power source 401 when the balloon 103 is retracted, so as to play a guiding role in the retracted mounting frame 102 through the guide plate 405, enabling it to be accurately retracted into the receiving box 301. And the pest control lamp after retraction is located on the side wall of the guide plate 405 away from the mounting frame 102, so that the pest control lamp after retraction can continue to be turned on to drive away pests around the receiving box 301, and the structural design is ingenious.

[0046] Please refer to Figure 1 and Figure 10 The ultrasonic pest control unit further includes a fourth rotating column 501, a second bevel gear set 502, a counterweight 504 and a fourth rotary power source 503; The fourth rotary power source 503 is not limited here. Its function is to provide rotational power and can be an AC motor, a stepper motor, etc.; The ultrasonic transmitter 101 is fixedly installed on the fourth rotating column 501. The fourth rotating column 501 is rotatably installed on the mounting frame 102. The rotation axis of the fourth rotating column 501 is horizontally arranged and parallel to the length direction of the mounting frame 102. The fixed end of the fourth rotation power source 503 is fixedly installed on the mounting frame 102. The rotating end of the fourth rotation power source 503 is fixedly connected to one end of the second bevel gear set 502, and the other end of the second bevel gear set 502 is fixedly connected to the fourth rotating column 501. The counterweight 504 is installed on the mounting frame 102. The counterweight 504 is used to balance the weights of the fourth rotating column 501 and the second bevel gear set 502, so that the mounting frame 102 rises smoothly during the ascent of the balloon 103.

[0047] In this embodiment, when it is necessary to adjust the insect repelling angle of the ultrasonic transmitter 101 along the width direction of the mounting frame 102, the fourth rotation power source 503 rotates to drive the fourth rotating column 501 to rotate by a corresponding angle, so that the ultrasonic transmitter 101 rotates by a certain angle in the width direction of the mounting frame 102. When it is necessary to adjust the insect repelling angle of the ultrasonic transmitter 101 along the length direction of the mounting frame 102, the third rotation power source 305 on the corresponding side in the length direction of the mounting frame 102 drives the corresponding rotating shaft 303 to rotate. This rotating shaft 303 drives the corresponding rope 302 to wind a certain length of the rope 302 on the rotating shaft 303, while the third rotation power source 305 on the other side does not rotate, thereby pulling the mounting frame 102 to tilt towards one side in the length direction of the mounting frame 102, so that the ultrasonic transmitter 101 rotates by a certain angle in the length direction of the mounting frame 102.

[0048] After the ultrasonic transmitter 101 of the present invention is driven by the balloon 103 to rise in the air, when it is necessary to adjust the irradiation angle of the ultrasonic transmitter 101, the fourth rotation power source 503 can be used to drive the fourth rotating column 501 to rotate by a corresponding angle, so that the ultrasonic transmitter 101 rotates by a certain angle in the width direction of the mounting frame 102. It is also possible to drive the corresponding rotating shaft 303 to rotate by the third rotation power source 305 on the corresponding side in the length direction of the mounting frame 102, and drive the ultrasonic transmitter 101 to rotate by a certain angle in the length direction of the mounting frame 102 by pulling the rope 302 on one side, so that multi-angle ultrasonic insect repelling of crops can be realized, and the range of ultrasonic insect repelling is wider.

[0049] Please refer to Figure 6 , the system further includes a third telescopic power source 601, a mounting column 602 and a sliding column 603; No limitation is imposed on the third telescopic power source 601 here. Its function is to provide telescopic power and can be a cylinder, a hydraulic cylinder, etc. The installation column 602 is fixedly installed on the ground. The fixed end of the third telescopic power source 601 is fixedly installed inside the installation column 602. The telescopic direction of the third telescopic power source 601 is vertically arranged. The sliding column 603 is fixedly connected to the lower end surface of the accommodation box 301. The extending end of the third telescopic power source 601 is fixedly connected to the sliding column 603. The sliding column 603 drives the accommodation box 301 to move up and down under the action of the third telescopic power source 601.

[0050] In this embodiment, when the crops around the accommodation box 301 grow higher than the accommodation box 301, before pest control, the third telescopic power source 601 first extends to raise the accommodation box 301 above the crops, and then subsequent pest control operations are carried out.

[0051] During pest control, the accommodation box 301 of the present invention can rise a certain distance under the action of the third telescopic power source 601, so that the accommodation box 301 is higher than the crops, so that when the subsequent guide plate 405 rotates from the vertical state to the horizontal state and spreads out on the outer side wall of the telescopic frame 402 under the action of the elastic hinge 404, the crops will not be crushed.

[0052] Please refer to Figure 1 , the system further includes a first guide pipe 701 and a second guide pipe 702; The first guide pipe 701 is fixedly connected to the accommodation box 301 and is located at the junction between two of the outer side walls of the accommodation box 301. The guiding axis of the first guide pipe 701 is vertically arranged; The second guide pipe 702 is fixedly connected to the installation box 203, and the second guide pipe 702 sequentially penetrates through the upper end surface of the installation box 203 and the ground and extends above the ground. The guiding axis of the second guide pipe 702 is vertically arranged, and the axial extension line of the second guide pipe 702 coincides with the axial extension line of the first guide pipe 701. The hose 201 in the installation box 203 sequentially passes through the second guide pipe 702 and the first guide pipe 701 and then communicates with the balloon 103; The inner diameter of the inner wall of the first guide pipe 701 is the same as the inner diameter of the inner wall of the second guide pipe 702, and the inner diameter of the inner wall of the first guide pipe 701 is larger than the outer diameter of the hose 201.

[0053] In this embodiment, when it is necessary to release the balloon 103 for pest control, when the balloon 103 is filled with a gas with a density lower than that of air through the hose 201, the hose 201 extending out of the installation box 203 sequentially passes through the second guide pipe 702 and the first guide pipe 701 and then communicates with the balloon 103. When it is necessary to retract the balloon 103 after the pest control is completed, the hose 201 above the first guide pipe 701 is wound around the first rotating column and sequentially passes through the first guide pipe 701 and the second guide pipe 702 and then enters the installation box 203.

[0054] The first guiding tube 701 of the present invention is located at the junction between two outer side walls of the accommodating box 301, so as to guide the hose 201 above the first guiding tube 701, so that when the subsequent guiding plate 405 rotates from the horizontal state to the outer side wall of the telescopic frame 402 to the vertical state under the action of the elastic hinge 404, the hose 201 will not be clamped, that is, the hose 201 avoids the rotation path of the guiding plate 405, thereby playing a role in protecting the hose 201.

[0055] The above embodiments are only illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention.
