Description

Technical Field

[0001] This invention relates to the field of termite control technology, and in particular to a volatile termite control machine and method for use on river embankments. Background Technology

[0002] Termite damage poses a significant safety hazard to water conservancy projects and is one of the contributing factors to major emergencies along river embankments. Traditionally, liquid insecticides are used to disinfect termites, but this not only pollutes the soil but is also inefficient. How to achieve green and non-destructive termite control and construct a comprehensive termite prevention and control system for embankments is a pressing problem that needs to be solved in current water conservancy projects. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a termite extermination machine and method for river embankments, which can achieve green and non-destructive termite extermination.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0005] A termite extermination machine for river embankments includes a wind power transmission device, a ventilation and circulation sealing device, a pill-wrapping device, and a heating device.

[0006] The wind power transmission device includes a blower and a splicing rod; the splicing rod is composed of multiple splicing connecting rods; ventilation ducts and electrical wires are installed inside the splicing rod, wherein the blower is connected to the ventilation duct, and the lower end of the ventilation duct extends out of the splicing rod; one end of the electrical wire is connected to the computer monitoring platform, and the other end supplies power to the pill wrapping device and the heating device;

[0007] The pill-wrapping device includes a four-bar linkage, one end of which is rotatably mounted on the end of the splicing rod, and the other end drives a serrated gripper to clamp or release the pill.

[0008] The heating device includes a resistance wire, which is placed in a serrated jaw and heats the pill.

[0009] The ventilation and circulation sealing device is installed on the splicing rod at the top of the pill wrapping device. The ventilation and circulation sealing device includes an umbrella frame structure. The connecting slider of the umbrella frame structure is slidably installed on the splicing rod. One side of the connecting slider is hinged to the connecting rod, and the other end of the connecting rod is hinged to the pill wrapping device. The connecting slider slides up and down through a traction mechanism and drives the pill wrapping device to rotate.

[0010] Both ends of the splicing connecting rod are provided with solid ends, and the outer end face of the solid ends is provided with a plug-in part. The two ends of the splicing connecting rod are plugged and clamped together through the plug-in part.

[0011] One end of the wire is inserted into the connector at one end of the splicing rod via a plug, and the other end of the wire is inserted into the connector at the other end of the splicing rod via a slot. Both ends of the ventilation duct are inserted into the connectors at both ends of the splicing rod via inserts. When adjacent splicing rods are connected, the plug and the slot are connected and conductive. The inserts of the ventilation ducts are connected to each other.

[0012] The outer walls of the solid ends of both ends of the splicing connecting rod are provided with limiting rings. A ring-shaped connector is connected to the limiting ring at one end of the splicing connecting rod by a spring. The end of the ring-shaped connector is provided with a locking head. The limiting ring at the other end of the splicing connecting rod is provided with a locking groove. When the two splicing connecting rods are inserted, the locking head is inserted into the locking groove. The side wall of the insertion part at one end of the splicing connecting rod is provided with a through hole. The insertion part at the other end of the splicing connecting rod is provided with a placement hole. The locking ball is placed in the placement hole and pressed into the through hole by the inner limiting ring of the ring-shaped connector.

[0013] The four-bar linkage includes an electric push rod, which is rotatably connected to the lower base at the end of the splicing connecting rod; a mounting base is fixed on the electric push rod, and a first connecting rod is hinged to the upper and lower parts of the mounting base; the other end of the first connecting rod is hinged to the rear end of the mounting part of the serrated gripper; a connector is fixed on the output rod of the electric push rod, and one end of the second connecting rod is hinged to the connector, and the other end is hinged to the front end of the mounting part of the serrated gripper.

[0014] The serrated gripper has multiple serrations on the inside.

[0015] The umbrella frame structure includes a pole, the first end of which is hinged to a splicing connecting rod, the middle end of which is hinged to one end of a support rod, and the other end of the support rod is hinged to a connecting slider; a windproof cloth is installed on the outside of the pole.

[0016] The traction mechanism includes a slider cable. One end of the slider cable passes around a pulley inside the splicing rod and is connected to the connecting slider. The other end of the slider cable is placed outside the splicing rod and is connected to a handle. When the handle moves up and down, it pulls the connecting slider up and down.

[0017] The connecting slider is circular, and a positioning pin is installed on the inner side of the connecting slider. The corresponding splicing connecting rod has a pin groove along the axial direction. The positioning pin slides up and down along the pin groove. When the positioning pin is at the bottom of the pin groove, the ventilation circulation sealing device is not activated and the pill wrapping device is in a vertical state. When the positioning pin is at the top of the pin groove, the ventilation circulation sealing device is activated and the pill wrapping device is in a horizontal state.

[0018] A method for termite extermination on river embankments includes the following steps:

[0019] Step 1: First, determine the number of connecting rods to be installed based on the drilling depth. Then, add or remove the number of connecting rods installed on the connecting rods above the ventilation circulation sealing device. Next, activate the electric push rod to open the serrated jaws, place the pill into the serrated jaws, and then clamp the pill with the serrated jaws. Then, place the pill packaging device and connecting rods into the hole, and the pill packaging device will be delivered underground through the connecting rods. Finally, connect the ventilation duct and wires at the top of the connecting rods to the blower and monitoring computer on the ground.

[0020] Step 2: Lift the connecting slider upwards by pulling the slider cable, and tighten the cable after it reaches the desired position; when the positioning pin on the inner side of the connecting slider moves to the upper limit position with the connecting slider, the pill wrapping device is in a horizontal state, that is, the pill wrapping device changes from a vertical state to a horizontal state, and the ventilation circulation sealing device unfolds and seals.

[0021] Step 3: At the same time, power is supplied to the wire to heat the resistance wire, start the electric push rod, and continue to slowly clamp the serrated claws to better fit the pill and heat the pill into gas; start the blower to deliver air to the ventilation duct. The outlet of the ventilation duct is located below the windproof cloth. The blower blows air out from below the windproof cloth and blows it toward the pill. The wind blows the gas from the pill toward the ant nest.

[0022] Step 4: The computer monitors the airflow, opening and closing angle, dosage, and heating temperature through sensors. After the termites are disinfected, the slider pulls the line to release the line, and the connecting slider descends, changing the pill-wrapping device from a horizontal to a vertical state. The ventilation and circulation sealing device closes and releases the seal. Then, the device is lifted by the splicing rod and taken out for disassembly.

[0023] This invention provides a termite extermination machine and method for use on river embankments, which has the following technical effects:

[0024] 1) This invention includes a pill-wrapping device, a heating device, a wind-powered delivery device, and a ventilation and circulation sealing device. The pill-wrapping device can be delivered underground via a connecting rod. The heating device heats and volatilizes the capsules. Activating the wind-powered delivery device and the ventilation and circulation sealing device enables effective diffusion of the gaseous pesticide within the termite nest system. This not only avoids damage to the surrounding soil caused by liquid pesticide penetration or other methods, but also achieves effective extermination throughout the entire termite nest space. It provides an effective solution for termite control.

[0025] 2) Because each connecting rod has wires and ventilation ducts encapsulated at both ends, identical connecting rods can be assembled one by one for different distances. The number of connecting rods to be assembled depends on the depth of the hole. For example, for long distances, more connecting rods can be assembled to deliver the pill-wrapping device underground. Therefore, it is suitable for ant nests of different distances.

[0026] 3) The main body of the wind power transmission device consists of a series of identical interlocking connecting rods, suitable for ant nests of varying distances. The number of connecting rods depends on the depth of the nest. Each connecting rod contains ventilation ducts and electrical wires, both ends of which are sealed and secured for better alignment and to prevent movement. This also prevents air from escaping. Once the connecting rods are interlocked and locked, ventilation and electricity are provided. The electricity powers the resistance wire, electric actuator, and sensors, while the airflow propels the gas from the pills towards the ant nest. The movable ring connector in the interlocking structure allows for convenient and quick interlocking, locking, and disassembly of the connecting rods.

[0027] When locked, the ring connector can press down on the locking ball, which enhances the stability and tightness of the connection compared to ordinary locking balls, making it more reliable when subjected to external forces. The locking head and slot can restrict circumferential rotation and can also be used for positioning, ensuring accurate connection of internal ventilation ducts and wires. Furthermore, the fixed wires, ventilation ducts, and limit rings can also serve as guide components, ensuring that all parts can be precisely aligned during the connection process, avoiding the problem of uneven connection in traditional designs.

[0028] 4) The ventilation circulation sealing device and the pill wrapping device can be linked. By connecting the ventilation circulation sealing device and the pill wrapping device through a slider and two rods, the machine can easily and quickly unfold the ventilation circulation sealing device to block the wind and change the pill wrapping device from a vertical to a horizontal position with fewer mechanisms. At the same time, the wind force pushes the ventilation circulation sealing device upward, which can partially offset the weight of the pill wrapping device, and the pill wrapping device can also better maintain a horizontal position.

[0029] The connecting slider is circular with a locating pin on its inner side. A corresponding connecting rod with a pin groove limits the slider's position. When the slider is at its lowest point, the pill-wrapping device is vertical; when it is at its highest point, it is horizontal. One end of the slider's pull cable is inside the locating pin, allowing for flexible up-and-down movement of the slider. A support rod is also connected to one end of the slider. The slider's movement up and down opens and closes the windproof cloth of the ventilation and circulation sealing device. The windproof cloth is circular and airtight, with an opening diameter slightly larger than the hole's diameter, allowing it to better press against the hole when open.

[0030] 5) The air circulation sealing device and the pill encapsulation device can be linked. The serrated grippers have multiple serrations on their inner side. Two serrated grippers can better hold the pill, ensuring it is delivered vertically to the ground without falling. The serrated grippers contain a resistance wire that heats the pill into a gas. A temperature sensor is fixed to the inner surface of the serrated grippers to monitor the heating temperature. The opening and closing of the grippers is achieved through an electric push rod and a four-bar linkage. The four-bar structure provides better support for the serrated grippers, making their opening and closing smoother. On the ground, the serrated grippers are opened to place the pill, and then the grippers are tightened to prevent the pill from falling vertically. When heating the pill, the electric push rod slowly tightens the grippers further, ensuring a better fit and more thorough heating. Attached Figure Description

[0042] like Figures 1-2As shown, a termite extermination machine for river embankments includes a computer monitoring platform 1, a wind-powered transmission device 2, a ventilation and circulation sealing device 3, a pill-wrapping device 4, and a heating device 5. The blower 201 of the wind-powered transmission device 2 and the computer monitoring platform 1 are located on the ground, while the main body of the machine—the wind-powered transmission device 2, the ventilation and circulation sealing device 3, the pill-wrapping device 4, and the heating device 5—are located underground.

[0043] Specifically, the computer monitoring platform 1 can monitor the temperature of the temperature sensor, the air volume of the blower 201, the opening and closing angle of the serrated gripper 405, and the dosage of the pill 6.

[0044] Air volume is measured using a differential pressure air volume sensor: pressure sensors are placed at both ends of the ventilation duct, and the ventilation volume is calculated by measuring the pressure difference generated when the airflow passes through the duct.

[0045] Using a tilt sensor to measure the opening and closing angle: A tilt sensor is placed on the gripper to detect the tilt angle of the object, suitable for angle detection in the vertical or horizontal direction.

[0046] Dosage is measured using a chemical sensor (gas resistive sensor): this method utilizes the change in resistance caused by the reaction of gas on the sensor surface. The higher the gas concentration, the more pronounced the change in resistance. The dosage of the gaseous drug can then be calculated by multiplying the gas concentration by the airflow rate by the time.

[0047] The dosage of 6 pills per dose depends on the size of the ant nest.

[0048] The overall height of this device depends on the depth of the ant nest, and the length of the connecting rod is adjustable. The diameter of the hole is about 10cm, and the ventilation and circulation sealing device 3, when fully extended, should be slightly larger than the diameter of the hole, about 12cm.

[0049] like Figures 3-6 As shown, specifically, the wind power transmission device 2 is responsible for transmitting wind and electricity, and the wind power transmission device 2 includes a blower 201 and a splicing rod.

[0050] The splicing rod is composed of multiple splicing connecting rods 202. Each splicing connecting rod 202 has a solid end 208 at both ends, and a limiting ring 209 is provided on the outer wall of each solid end 208. The outer end face of the solid end 208 has an insertion part 210, which is a sleeve structure. The insertion parts 210 at both ends of the splicing connecting rod 202 can fit together and abut against the end face of the other solid end 208. In this way, when adjacent splicing connecting rods 202 are spliced, the insertion parts 210 of the two splicing connecting rods 202 can be inserted into each other. At the limiting ring 209 at one end of each splicing connecting rod 202, a ring connector 203 is connected by a spring 204. The ring connector 203 is a tubular structure with open ends and can slide along the length of the limiting ring 209. A slot 211 is provided at the limiting ring 209 at the other end of each interlocking connecting rod 202, and a locking head 212 is provided at the corresponding end of the annular connector 203. The locking head 212 can be inserted into the slot 211, thereby restricting the circumferential movement of the annular connector 203. A through hole 213 is provided on the side wall of the insertion part 210 (with a smaller inner diameter) at one end of each interlocking connecting rod 202, and a placement hole 214 is provided on the side wall of the insertion part 210 (with a larger inner diameter) at the other end of each interlocking connecting rod 202. The diameter of the placement hole 214 is larger than the diameter of the through hole 213. A retaining ball 205 is placed in the placement hole 214. Since the diameter of the placement hole 214 gradually decreases at the inward end (towards the through hole 213), while the diameter of the placement hole 214 remains unchanged at the outward end, the retaining ball 205 can partially extend out of the placement hole 214 and be inserted into the through hole 213.

[0051] like Figures 4-5 As shown, when the two interlocking connecting rods 202 are inserted, firstly, push the annular connector 203 of the interlocking connecting rod 202 to the right so that the inner limiting ring of the annular connector 203 is located on the right side of the mounting hole 214. Then, insert the insertion part 210 (with a larger inner diameter) of the other interlocking connecting rod 202 into the insertion part 210 (with a smaller inner diameter) of the first interlocking connecting rod 202. After the two interlocking connecting rods 202 are inserted, the annular connector 203 is released. Under the action of the spring 204, the annular connector 203 moves to the left, and the inner limiting ring of the annular connector 203 presses the locking ball 205 into the through hole 213. In this way, the insertion parts 210 of the two interlocking connecting rods 202 are locked together and can withstand a large weight. At the same time, the locking head 212 at the end of the annular connector 203 of this interlocking connecting rod 202 is inserted into the locking groove 211 of the other interlocking connecting rod 202, thereby restricting circumferential rotation and ensuring stable locking.

[0052] When the two interlocking connecting rods 202 need to be disassembled, push the annular connecting head 203 to the right. The annular connecting head 203 moves axially to the right, and the locking head 212 of the annular connecting head 203 disengages from the locking groove 211 of the other interlocking connecting rod 202 and gradually compresses the spring 204. When the inner limiting ring of the annular connecting head 203 is located on the right side of the mounting hole 214, pull the other interlocking connecting rod 202 to the left. Under the action of the pulling force, the locking ball 205 can move outward and move out of the through hole 213, and the two interlocking connecting rods 202 can be disassembled.

[0053] The above structure allows the two interlocking connecting rods 202 to be securely connected, and the connection and disassembly are convenient.

[0054] like Figures 3-4 As shown, each interlocking connecting rod 202 is hollow inside, with a ventilation duct 206 and an electrical wire 207 in the middle. Since both ends of the interlocking connecting rod 202 are solid (208), the ventilation duct 206 and electrical wire 207 can be sealed. The advantage of sealing both ends is that it can fix the ventilation duct and electrical wire inside the interlocking connecting rod 202, making it better aligned with the interlocking ventilation duct, preventing the ventilation duct and electrical wire from shaking, and also preventing the ventilation from escaping from the interlocking connecting rod 202.

[0055] For ease of installation, the ventilation duct 206 and the electrical wire 207 are located at the solid end 208 of one splice connecting rod 202 and the solid end 208 of another splice connecting rod 202, respectively, and are connected by a plug-in joint to maintain ventilation and power supply. That is, the inner diameter of one end of the ventilation duct 206 on the same splice connecting rod 202 is the outer diameter of the other end of the ventilation duct 206; one end of the electrical wire 207 is a copper wire, and the other end of the electrical wire 207 is a slot with an outer positive and inner round shape, which can be plugged into each other for power transmission.

[0056] The wire 207 is connected to the slot at the plug-in part 210 via a plug wire; the ventilation ducts 206 are connected to each other at the plug-in part 210 via insert tubes; because the splicing connecting rod 202 is used to accommodate ant nests of different distances, each splicing connecting rod 202 seals and fixes the ventilation duct 206 and the wire 207. When two splicing connecting rods 202 are spliced, the ventilation duct 206 and the wire 207 can be connected to conduct air and electricity.

[0057] Because ant nests vary in distance underground, and the interlocking connecting rods 202 can be assembled section by section, they are suitable for transmitting air, electricity, and delivering medicine pills in caves of different distances, offering greater versatility. When the ant nest is located a long distance underground, the interlocking connecting rods can be assembled to extend the distance, providing sufficient distance to deliver the medicine pills to the vicinity of the ant nest, resulting in better operational effectiveness.

[0058] Existing umbrella poles or other pole connectors also use springs and ball-locking mechanisms. Compared to those structures, the advantages of this connector structure are: this connector structure is detachable, and the pole diameter does not decrease, while existing umbrella poles are retractable, non-detachable, and their diameter decreases over time. The annular connector 203 is movable. When locked, the annular connector 203 can press against the ball-locking mechanism 205, enhancing the stability and tightness of the connector compared to ordinary ball-locking mechanisms, making it more reliable under external forces. To disassemble, moving the annular connector 203 allows for quick disassembly. The locking head 212 and the locking groove 211 can restrict circumferential rotation and also provide positioning, ensuring accurate insertion of the internal ventilation duct 206 and wire 207. Furthermore, the fixed wire, ventilation duct, and limiting ring can also serve as guide components, ensuring precise alignment of all parts during the insertion process and avoiding the misalignment issues found in traditional designs.

[0059] like Figure 7 As shown, the pill encapsulation device 4 includes an electric push rod 401, a first connecting rod 402, a connector 403, a second connecting rod 404, and a serrated gripper 405.

[0060] An electric actuator 401 is mounted on a lower base 407 at the lower end of the connecting rod 202, and the electric actuator 401 is rotatably connected to the lower base 407. A mounting base 406 is fixed to the outer casing of the electric actuator 401. Two first connecting rods 402 are arranged vertically, with one end hinged to the mounting base 406, and the other end hinged to the rear end of the mounting portion of the serrated gripper 405. A connector 403 is fixed to the output rod of the electric actuator 401. One end of a second connecting rod 404 is hinged to the connector 403, and the other end is hinged to the front end of the mounting portion of the serrated gripper 405. When the output rod of the electric actuator 401 extends or retracts left or right, the enclosing portion of the serrated gripper 405 opens or closes. The four-bar linkage structure makes the opening and closing of the serrated gripper 405 smoother.

[0061] The serrated grippers 405 have multiple serrations on their inner sides, and two serrated grippers 405 clamp the pill 6. A resistance wire is inside each serrated gripper 405, and the resistance wire is connected to a power source via an electrical wire to heat the pill 6. Additionally, a temperature sensor is fixed to the inner surface of each serrated gripper 405 for temperature detection.

[0062] Multiple serrations can better grip the pill 6, the resistance wire can heat the pill 6, and the temperature sensor can measure the heating temperature.

[0063] The pill-wrapping device can be rotatably installed; the advantage of rotating it 90 degrees is that the hole drilled for termite removal in this application is L-shaped, and initially the machine... Figure 1Enter vertically, then pull the line. The connecting slider 304 will rise. The connecting slider 304 and the entire pill-wrapping device gripper are connected by two rods, which will drive the entire pill gripper from a vertical state to a horizontal state, aligning it with the ant nest. The entire machine will then become L-shaped. At the same time, the structure of the ventilation circulation sealing device's windproof cloth will also unfold to seal it, allowing the pill to get closer to the ant nest for better insecticidal effect.

[0064] like Figures 8-10 As shown, the ventilation circulation sealing device 3 includes a rod 301, a support rod 302, a windproof cloth 303, a connecting slider 304, a connecting rod 305, a pulley 306, and a slider pull line 307.

[0065] like Figure 8 As shown, the windproof cloth 303 is fixed to the pole 301. The windproof cloth 303 is made of an airtight material and, when opened, rests against the ant nest's hole passage. The first end of the pole 301 is hinged to the splicing connecting rod 202, and the middle end is hinged to one end of the support rod 302. The other end of the support rod 302 is hinged to the connecting slider 304.

[0066] The connecting slider 304 is annular with a positioning pin on its inner side. The splicing connecting rod 202 that matches the positioning pin has a pin groove along the axial direction. The connecting slider 304 can slide up and down along the pin groove of the splicing connecting rod 202 through the positioning pin.

[0067] One end of the two connecting rods 305 is hinged to the connecting slider 304, and the other end is hinged to the mounting base 406 of the electric push rod 401.

[0068] like Figures 9-10 As shown, the ventilation circulation sealing device 3 is linked to the pill wrapping device 4 by two connecting rods 305. At the same time, the pin groove limits the connecting slider 304. When the connecting slider 304 is at the bottom of the pin groove, the ventilation circulation sealing device 3 is not activated and the pill wrapping device 4 is in a vertical state; when the connecting slider 304 is at the top of the pin groove, the ventilation circulation sealing device 3 is activated and the pill wrapping device 4 is in a horizontal state.

[0069] like Figure 8 As shown, one end of the slider cable 307 is inside the positioning pin of the connecting slider 304, and the other end passes through the pulley 306 inside, with its handle located on the outside. This allows for convenient and quick control of the raising and lowering of the connecting slider 304, while the internal placement of the slider cable 307 reduces external interference. One end of the slider cable 307, inside the positioning pin of the connecting slider 304, allows for flexible pulling of the connecting slider up and down. A support rod is also connected to one end of the connecting slider. The raising and lowering of the connecting slider opens and closes the windproof cloth 303 of the ventilation circulation sealing device 3, and simultaneously changes the pill-wrapping device 4 from a vertical to a horizontal state.

[0070] In this application, the other end of the slider pull line 307 can be tied and fixed after it is in place. When the wind power transmission device 2 is in a vertical state, it needs to be manually assisted to send the machine to the ground. After the machine is turned into a horizontal state, it can be placed underground to wait for the termite extermination to be completed.

[0071] Working process and principle:

[0072] Air and electricity are transmitted through interlocking connecting rods.

[0073] First, determine the number of connecting rods to be inserted based on the drilling depth. Then, install the sensor on the pill-wrapping device 4, insert the connecting rods one by one, start the hydraulic motor to open the serrated jaws, place the pill into the serrated jaws, and then clamp the pill with the serrated jaws. Then, put the pill-wrapping device and connecting rods into the hole. The pill-wrapping device 4 is then connected to the ground through the connecting rods, and the pill-wrapping device clamps the pill. The ventilation duct and wire at one end of the uppermost connecting rod are connected to the blower and monitoring computer on the ground, respectively.

[0074] The pill wrapping device 4 wraps and opens the pill, the heating device 5 heats the pill into gas, and controls the ventilation of the wind power transmission device 2 to effectively diffuse the pill gas, while the ventilation circulation sealing device 3 seals the pill gas and the wind.

[0075] During operation, one end of the slider pull wire 307 is inside the positioning pin connecting the slider 304, allowing for flexible pulling and moving the connecting slider 304 up and down. One end of the connecting slider 304 is also connected to the support rod 302. The rise and fall of the connecting slider 304 opens and closes the windproof cloth 303 of the ventilation circulation sealing device 3. Simultaneously, the wind force pushes the windproof cloth 303 upwards, partially offsetting the weight of the pill-wrapping device 4, thus better maintaining the pill-wrapping device 4's horizontal position. The hole is a round hole, approximately 10cm in diameter. The diameter of the windproof cloth after it is unfolded is slightly larger than the hole's diameter, about 12cm, allowing the windproof cloth to effectively cover the hole. In this device, the windproof cloth 303 is made circular, and its unfolded diameter is slightly larger than the hole's diameter, allowing it to be pressed against the hole by the pull force of the pull wire (primarily) and the thrust of the wind, achieving a seal. Data parameters are monitored on the computer monitoring platform 1.

[0076] Additionally, when locating an ant nest, the initial drilling is based on an estimated location and is unlikely to hit the exact top of the nest vertically; it will usually deviate. A second radar positioning is needed to search horizontally for the precise location of the ant nest, so most of the drilled holes will be L-shaped. The pill-encapsulating device 4 needs to be horizontal so that the opening of the grippers faces the ant nest, facilitating the delivery of the drug gas.

[0077] Because the hole has a small diameter and is L-shaped, the pill-wrapping device 4 and the wind-powered conveying device 2 are initially in a vertical position, and then they are turned into an L-shape, aligning the pill-wrapping device 4 with the ant nest. The linkage operation of the ventilation circulation sealing device 3 and the pill-wrapping device 4 is an innovation. By linking the ventilation circulation sealing device 3 and the pill-wrapping device 4 through the connecting slider 304 and two rods, the machine can achieve ventilation circulation sealing in a convenient and quick way with fewer mechanisms. At the same time, the pill-wrapping device changes from a vertical to a horizontal position, aligning with the ant nest to facilitate the delivery of the medicine gas. Meanwhile, the wind pushes the ventilation circulation sealing device 3 upward, and the wind force can partially offset the weight of the pill-wrapping device 4, allowing the pill-wrapping device 4 to maintain a better horizontal position.
