Technical Field
[0001] This invention belongs to the field of agricultural machinery technology, specifically relating to an intelligent rice harvester based on layered cutting and water curtain anti-fouling. Background Technology
[0002] Rice is a monoecious crop, and superior rice varieties have a significant impact on rice quality. Therefore, hybrid vigor can be used to improve rice quality through seed production. In hybrid rice breeding, the harvesting of the male parent plant plays a crucial role in ensuring seed purity. Before harvesting, the male parent plant must be removed to ensure seed purity. During breeding, male parent plants are often planted in single or double rows. If traditional small harvesters are used for harvesting the male parent, the simple design of the cutting components often results in a large amount of debris being scattered. This debris can easily mix into the female parent area, severely affecting seed purity.
[0003] Currently, the market's specific needs for paternal parent harvesting, such as pollution control and intelligent adaptation, have not yet been specifically optimized. Therefore, how to provide a dedicated paternal parent harvesting device that can achieve efficient layered cutting, dynamically prevent splash contamination, and integrate intelligent recognition and navigation functions to meet the dual requirements of seed purity and operational efficiency in hybrid rice seed production scenarios is a problem that urgently needs to be solved by those skilled in the art.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0028] like Figures 1-8As shown, this invention provides an intelligent rice harvester based on layered cutting and water curtain anti-fouling, including a header 3, a vehicle body 12, a tracked chassis 11, and a connecting bridge 9. The header 3 has a material discharge port on one side and a rice feed port on the side corresponding to the material discharge port. The vehicle body 12 has a material feed port on one side and also includes a storage bin and a control chamber. The discharge port of the header 3 is connected to one end of the connecting bridge 9, and the other end of the connecting bridge 9 is connected to the material feed port of the vehicle body 12. An intelligent control module 14 is installed in the control chamber of the vehicle body 12. The tracked chassis 11 is connected to the bottom of the vehicle body 12. Module 14 is electrically connected to the track drive motor mounted on the tracked chassis 11. The header 3 is also connected to a blower mechanism 6 and a water spraying mechanism. The top of the header 3 is connected to a reel 1. The intelligent control module 14 includes a Beidou navigation unit, a dynamic parameter matching unit, a central processing unit, and a battery. The Beidou navigation unit, the dynamic parameter matching unit, and the battery are all electrically connected to the central processing unit. The cooperation between the Beidou navigation unit, the dynamic parameter matching unit, and the central processing unit can monitor the position of the harvester at all times and move precisely in coordination with the tracked chassis 11 to ensure the automation of harvesting the parent rice plants and improve harvesting efficiency. The intelligent control module 14 can also be a PLC controller.
[0029] In this embodiment, the header 3 includes a header frame. A rice feed inlet and a shredded material outlet are respectively provided on opposite sides of the header frame. The end of the header frame with the shredded material outlet is connected to a connecting bridge 9. A cutter 4 is detachably connected to the bottom of the side of the header frame with the rice feed inlet. A layered wheel-type cutter 5 is rotatably connected inside the header frame. A cutter drive motor 18 is also provided on the outer wall of the header frame. The output end of the cutter drive motor 18 passes through the header frame and is connected to the layered wheel-type cutter 5. A reel support frame is connected to the top of the header frame. A reel 1 is rotatably connected to the reel support frame. The reel 1 is provided with multiple reeling teeth 2. A reel drive motor 17 is provided on the reel support frame. The output end of the reel is connected to the reel 1 through the reel support frame. The cutting blade drive motor 18 and the reel drive motor 17 are both electrically connected to the intelligent control module 14. The layered wheel cutting blade 5 can chop the rice parent plant multiple times to ensure smooth subsequent harvesting and avoid the rice parent plant being too long and causing blockage of the harvester. The connecting bridge 9 is used to connect the header 3 and the vehicle body 12 to ensure that the chopped rice parent plant is transported into the vehicle body 12. The connecting bridge 9 can also be equipped with a conveyor belt to transport the rice parent plant into the vehicle body 12. The cutting blade 4 is mainly used to cut the fallen rice parent plant from the bottom. The reel 1 drives the reeling spring 2 to rotate continuously by rotating, thereby using the reeling spring 2 to pull the rice parent plant down onto the header 3.
[0030] In this embodiment, the layered wheel-type cutting blade 5 includes an outer flat blade assembly 501, an inner serrated blade assembly 502, a cutting blade drive shaft, and an intermediate fixing plate 503. The outer flat blade assembly 501 and the inner serrated blade assembly 502 are both sleeved on the cutting blade drive shaft. The inner serrated blade assembly 502 is located inside the outer flat blade assembly 501. The middle position of the outer flat blade assembly 501 is fixedly connected to the intermediate fixing plate 503 through the intermediate fixing plate 503. The inner serrated blade assembly 502 and the outer flat blade assembly 501 are rotatably connected to the inner wall of the cutting platform 3 through the cutting blade drive shaft. The output end of the cutting blade drive motor 18 passes through the outer wall of the cutting platform 3 and is connected to the cutting blade drive shaft. The outer flat blade assembly 501 performs the first cut on the rice parent plant, and the inner serrated blade assembly 502 performs the second cut and crushing on the rice parent plant, ensuring that the rice parent plant can be crushed for subsequent tasks. The crushed parent plant is blown into the vehicle body 12 from the connecting bridge 9 through the blower mechanism 6.
[0031] In this embodiment, the blower mechanism 6 includes a blower frame, nozzles 601, an air duct, and a centrifugal fan 8. The centrifugal fan 8 is fixed to the outer wall of the cutter frame. Blower frames are provided on both sides corresponding to the rice feed inlet on the cutter frame. Multiple nozzles 601 are provided on the blower frame, and a ventilation cavity is provided inside the blower frame. The blower frame is connected to the multiple nozzles 601 through the ventilation cavity. The air outlet of the centrifugal fan 8 is connected to one end of the air duct. The end of the pipe away from the centrifugal fan 8 is connected to the ventilation cavity. The centrifugal fan 8 is electrically connected to the intelligent control module 14. The blower mechanism 6 is mainly set at the bottom of the rice feed inlet, and the nozzle 601 is mainly facing the inside of the rice feed inlet. This makes it convenient for the nozzle 601 to blow air from the bottom to blow the chopped rice parent plant fragments into the rice feed inlet, preventing the rice parent plant fragments from floating out of the rice feed inlet and contaminating the rice mother plant area. The air blown out by the centrifugal fan 8 passes through the air pipe and the ventilation cavity and is then blown out from the nozzle.
[0032] In this embodiment, the water spraying mechanism includes a water spraying bracket, water curtain nozzles 7, a water tank 10, water pipes, and a water pump. The water tank 10 is fixed to the outer wall of the cutter frame. A water level sensor is installed inside the water tank 10, and the water level sensor is electrically connected to the intelligent control module 14. Water spraying brackets are provided on both sides corresponding to the rice feed inlet on the cutter frame. A water passage cavity is provided inside the water spraying bracket, and multiple water curtain nozzles 7 are provided on the water spraying bracket. The multiple water curtain nozzles 7 on the water spraying bracket are connected to the water curtain nozzles 7 through the water passage cavity. The water curtain nozzle 7 is connected to one end of a water pipe through a water passage cavity. The other end of the water pipe extends into the water tank 10 and is connected to a water pump installed in the water tank 10. The water pump is electrically connected to the intelligent control module 14. The water spray bracket is mainly installed at the top of both sides of the rice feed inlet, which can spray water mist from a height to wet the dust and debris generated during cutting, so that the dust and debris can settle quickly, avoid the spread of debris, and prevent the rice male parent plant from contaminating the rice female parent plant planting area. In addition, the water level sensor can transmit signals to the intelligent control module 14 in a timely manner.
[0033] In this embodiment, the vehicle body 12 is also equipped with multiple image acquisition modules 16 and monitoring sensors 15. The inner wall of the storage bin on the vehicle body 12 is also equipped with a debris full-bin sensor 13. The image acquisition modules 16, monitoring sensors 15 and debris full-bin sensor 13 are all electrically connected to the intelligent control module 14. The image acquisition modules 16 are used to acquire images around the harvester to ensure the normal operation of the harvester. The monitoring sensors 15 can monitor the debris concentration at the debris outlet, which facilitates the intelligent control module 14 to control the water spray mechanism and the blower mechanism 6.
[0034] Working principle: Specifically, during the harvesting process, the machine first uses the reel 1 to rotate and pushes the rice parent plants onto the header 3 using the reel teeth 2; then the cutter 4 cuts the roots of the rice parent plants pushed onto the header 3; subsequently, the layered wheel-type cutter 5 performs preliminary cutting of the rice parent plants by the outer flat blade group 501, and then performs secondary crushing by the inner saw tooth group 502; then the blower mechanism 6 sends the crushed rice parent plants away from the header 3 and moves them to the vehicle body 12 via the connecting bridge 9, thereby completing the harvesting and collection of the rice parent plants. At the same time, the material full-bin sensor 13 can monitor the total amount of material in the storage bin inside the vehicle body 12.
[0035] During the harvesting of the male parent rice, water is pumped out from the water curtain nozzle 7 to prevent dust and debris generated during the harvesting process from combining with droplets under the turbulence of airflow. The wet particles settle quickly due to their increased weight. At the same time, the physical barrier effect of the water curtain effectively inhibits the lateral spread of debris and prevents male parent debris from contaminating the female parent area. Meanwhile, the debris concentration is monitored by the monitoring sensor 15, and the water pressure of the water curtain nozzle 7 is automatically adjusted to adjust the coverage angle to ensure a balance between anti-fouling efficiency and water-saving performance.
[0036] In addition, by using the intelligent control module 14 in conjunction with the monitoring sensor 15, the image acquisition module 16, and the Beidou navigation unit in the intelligent control module, automatic navigation can be achieved and the rice can be moved to a designated location to work, thus realizing the automation of rice harvesting.

Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
