Description

Technical Field

[0001] This utility model relates to the technical field of cotton harvester equipment, and more specifically, to a fire-retardant device for cotton harvesters. Background Technology

[0002] During the cotton harvesting process, the cotton harvester, as an important piece of machinery, undertakes the task of efficiently harvesting and transporting cotton. When the cotton harvester is running, its cotton conveying pipe is responsible for transporting the harvested cotton. However, due to the complex cotton harvesting environment, there may be various potential sources of fire, such as high temperatures generated by mechanical friction and static sparks. These factors may cause the cotton in the cotton conveying pipe to catch fire.

[0003] Currently, most fire monitoring and extinguishing systems for cotton harvesters are "post-incident" remedial measures, meaning that the fire has already occurred inside the cotton box before extinguishing it. Such fire extinguishing systems for cotton harvesters can result in significant economic losses to some extent.

[0004] A search revealed that Chinese patent CN212116247U discloses a fire-retardant device for cotton harvesters. This structure can directly remove burning cotton from the cotton harvester during the cotton conveying process, preventing it from entering the cotton box and igniting more cotton in the box, thereby achieving the purpose of blocking the fire source.

[0005] However, in actual use, this structure only discharges the burning cotton to the outside of the cotton harvester, making it difficult to extinguish the fire in time and prevent the fire from spreading further. Therefore, this utility model proposes a fire-retardant device for cotton harvesters. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a fire retardant device for cotton harvesters to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a flame-retardant device for a cotton harvester, comprising a flame-retardant pipe installed on the cotton conveying pipe of the cotton harvester for conveying cotton, a guide port being provided on the upper surface of the flame-retardant pipe, and a far-infrared sensor being installed at the top of the inner cavity of the flame-retardant pipe, the far-infrared sensor being located at the top of the inner cavity of the flame-retardant pipe and away from the guide port, the far-infrared sensor being detachably connected to the flame-retardant pipe by bolts, used to detect whether there is a spark signal in the cotton inside the pipe, and two connecting rods being arranged parallel to each other on the inner wall of the flame-retardant pipe at the guide port, the two connecting rods being fixedly connected together. A connecting pin is provided, and a connecting shaft is provided on one side of the connecting pin. A crank plate is rotatably provided on the outside of the connecting pin. Two crank rods are fixedly installed on the outside of the connecting shaft. A connecting rod plate is provided between the crank plate and the two crank rods. A shaft pin is provided at both ends of the connecting rod plate and the connection points of the crank plate and the crank rods, and they are movably connected by the shaft pin. A DC motor is installed on the flame-retardant tube. The DC motor is fixedly installed on the surface of the flame-retardant tube, and the output end of the DC motor is fixedly connected to the connecting shaft. The connecting shaft is rotatably connected between the two connecting rods. The DC motor is electrically connected to the far-infrared sensor.

[0008] As can be seen, this structure uses a far-infrared sensor to detect the signal of burning cotton, and transmits the processed signal to a DC motor. The DC motor drives the connecting shaft to rotate, which in turn causes the two cranks, connecting rod plate and crank plate to change their workings, thereby changing the original flow direction of the burning cotton in the flame-retardant tube.

[0009] To enable fire extinguishing of burning cotton by spraying, preferably, a spray structure is provided at the top of the flame-retardant tube and at the guide port. The spray structure includes an isolation chamber, which is fixedly installed on the surface of the flame-retardant tube and located at the guide port. A concave frame is installed on the isolation chamber, and multiple nozzles are provided on both inner walls of the concave frame. A storage chamber is provided at the top of the flame-retardant tube and on one side of the isolation chamber. A pump is provided on one side of the storage chamber. The input and output ends of the pump are respectively provided with a connecting pipe and a delivery pipe. The isolation chamber is connected to the flame-retardant tube through the guide port and is used to guide the burning cotton inside the flame-retardant tube into the interior of the isolation chamber. The multiple nozzles are all connected to the concave frame and extend into the interior of the isolation chamber. The pump is fixedly installed at the top of the flame-retardant tube, and the input and output ends of the pump are connected to the connecting pipe and the delivery pipe, respectively. One end of the connecting pipe extends into the interior of the storage chamber, and one end of the delivery pipe is connected to the concave frame.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. By setting up a spray structure, the burning cotton inside the flame-retardant tube is guided into the isolation chamber. The flame retardant or extinguishing agent in the storage chamber is transported through the connecting pipe and the delivery pipe by the pump and enters the concave frame. Finally, the flame retardant or extinguishing agent is delivered into the isolation chamber through multiple nozzles to extinguish the burning cotton, prevent the fire from spreading further, and improve safety.

[0012] 2. The infrared sensor detects the fire signal, processes the signal, and transmits it to the electrically connected DC motor. The DC motor drives the connecting shaft to rotate between two connecting rods fixed to the inner wall of the flame-retardant tube and located at the guide port. The rotation of the connecting shaft drives the two cranks fixedly installed on its outside to rotate. The rotation of the cranks drives the connecting rod plate to move through the shaft pin. The connecting rod plate then drives the crank plate, which is rotatable and sleeved outside the connecting pin, to rotate. This causes the entire structure to change angle, changing the original flow direction of the burning cotton in the flame-retardant tube and avoiding impact on the cotton harvester.

[0021] As attached Figure 1-6 The fire retardant device for a cotton harvester shown includes a flame-retardant pipe 1 installed on the cotton conveying pipe of the cotton harvester for conveying cotton. A guide port 2 is provided on the upper surface of the flame-retardant pipe 1, and a far-infrared sensor 3 is installed on the top of the inner cavity of the flame-retardant pipe 1.

[0023] Specifically, in this structure, the flame-retardant pipe 1 of the flame-retardant device is installed on the cotton conveying pipe of the cotton harvester for transporting cotton. When the cotton harvester encounters a fire, the initial state is as shown in the attached diagram. Figure 5 As shown, the far-infrared sensor 3 located inside the flame-retardant tube 1 can detect fire signals. These signals are processed and acquired by the DC motor 11. The DC motor 11 drives the connecting shaft 6 to rotate between the two connecting rods 4, and the connecting shaft 6 drives the two cranks 8 to rotate, causing the connecting rod plate 9 to drive the crank plate 7 to rotate, resulting in an angular change in the entire structure. This process can be referred to in the appendix. Figure 5 Become an appendix Figure 6 This changes the original flow direction of the burning cotton in the flame-retardant pipe 1, leading it out of the flame-retardant pipe 1 through the guide port 2 and into the spray structure for fire extinguishing.

[0024] In a specific embodiment, as shown in the appendix Figure 1 , 3As shown, a spray structure is provided at the top of the flame-retardant pipe 1 and at the guide port 2. The spray structure includes an isolation chamber 12, which is fixedly installed on the surface of the flame-retardant pipe 1 and located at the guide port 2. A concave frame 13 is installed on the isolation chamber 12, and multiple nozzles 14 are provided on both inner walls of the concave frame 13. A storage chamber 15 is provided at the top of the flame-retardant pipe 1 and on one side of the isolation chamber 12. A pump 16 is provided on one side of the storage chamber 15. A connecting pipe 17 and a delivery pipe 18 are respectively provided at the input and output ends of the pump 16. The isolation chamber 12 is connected to the flame-retardant tube 1 through the guide port 2, which is used to guide the burning cotton inside the flame-retardant tube 1 to the interior of the isolation chamber 12 through the guide port 2. Multiple nozzles 14 are connected to the concave frame 13 and extend into the interior of the isolation chamber 12. The pump 16 is fixedly installed on the top of the flame-retardant tube 1, and the input end and output end of the pump 16 are connected to the connecting pipe 17 and the conveying pipe 18, respectively. One end of the connecting pipe 17 extends into the interior of the storage chamber 15, and one end of the conveying pipe 18 is connected to the concave frame 13.

[0025] Specifically, in this structure, the burning cotton inside the flame-retardant tube 1 is guided into the isolation chamber 12. The flame retardant or extinguishing agent inside the storage chamber 15 is then transported by the pump 16 through the connecting pipe 17 and the delivery pipe 18 into the concave frame 13. Finally, the flame retardant or extinguishing agent is delivered into the isolation chamber 12 through multiple nozzles 14 to extinguish the burning cotton, prevent the fire from spreading further, and improve safety.

[0026] Working principle of this utility model:

[0027] This application provides a fire-retardant device for a cotton harvester, mainly composed of a fire-retardant pipe 1, a far-infrared sensor 3, a connecting rod 4, a connecting pin 5, a connecting shaft 6, a crank plate 7, a crank rod 8, a connecting rod plate 9, a DC motor 11, and a spray structure. The far-infrared sensor 3 detects the ignition of cotton during the cotton harvesting process, and guides the burning cotton to the spray structure for fire extinguishing by changing the flow direction of the burning cotton, so as to avoid the spread of fire and ensure the safe operation of the cotton harvester. Specifically;

[0028] When the cotton harvester is working, cotton is transported through a flame-retardant pipe 1 installed on the cotton conveying pipe of the harvester. A far-infrared sensor 3, installed at the top of the inner cavity of the flame-retardant pipe 1 and away from the guide port 2, continuously monitors the cotton inside the pipe for sparks. The far-infrared sensor 3 is detachably connected to the flame-retardant pipe 1 via bolts for easy installation and maintenance. When the cotton harvester encounters a fire, the far-infrared sensor 3 detects the fire signal, processes the signal, and transmits it to the electrically connected DC motor 11. Upon receiving the signal, the DC motor 11 starts. Since its output end is fixedly connected to the connecting shaft 6, the DC motor 11 drives the connecting shaft 6 to rotate between two connecting rods 4 fixed to the inner wall of the flame-retardant pipe 1 and located at the guide port 2. The rotation of the connecting shaft 6 drives the two cranks 8 fixedly installed externally to rotate. The rotation of the cranks 8 drives the connecting rod plate 9 to move via the shaft pin 10. The connecting rod plate 9 then drives the rotatable crank plate 7, which is sleeved outside the connecting pin 5, to rotate, causing the entire structure to change angle. This process can be seen in the attached diagram from the initial state. Figure 5 The state after transformation into an action Figure 6 This changed the original flow direction of the burning cotton in the flame-retardant tube 1;

[0029] The burning cotton is led out of the flame-retardant tube 1 through the guide port 2 opened on the upper surface of the flame-retardant tube 1. An isolation chamber 12 connected to the flame-retardant tube 1 is provided at the guide port 2, and the burning cotton is guided into the isolation chamber 12.

[0030] When the burning cotton enters the isolation chamber 12, the pump 16, which is installed on top of the flame-retardant pipe 1 and located on one side of the storage chamber 15, starts to work. The pump 16 extracts the flame retardant or extinguishing agent from the storage chamber 15 through the connecting pipe 17, and then transports it to the concave frame 13 connected to the conveying pipe 18 through the conveying pipe 18. The two inner walls of the concave frame 13 are provided with multiple nozzles 14 that are connected to the concave frame 13 and extend into the isolation chamber 12. The flame retardant or extinguishing agent is sprayed into the isolation chamber 12 through these nozzles 14 to extinguish the burning cotton, prevent the fire from spreading further, and improve the safety of the cotton harvester operation.

[0031] In summary, this application, based on existing technology, provides further fire extinguishing treatment for the ignited cotton, preventing the fire from spreading further and ensuring the safe conduct of cotton harvesting operations.
