Description

Technical Field

[0001] This invention relates to the field of rice harvesting, and more particularly to a rice harvesting device for agricultural production. Background Technology

[0002] In the entire rice production chain, from seedling raising, transplanting, field management to final harvesting, every link is crucial. Harvesting, as the final stage of the entire planting cycle, directly determines the return on all the labor and production materials invested in the earlier stages, and is a key factor affecting agricultural production efficiency. Traditional rice harvesting equipment has several technical problems during operation: First, the rice-lifting device is usually a fixed structure, unable to be flexibly adjusted according to the rice's growth height or lodging condition, resulting in poor lifting effect on short-stalked or lodged rice and a high rate of missed harvesting; second, the conveying device is prone to uneven conveying, blockages, or rice scattering when transporting the cut rice backwards, affecting the continuity of subsequent processing steps.

[0003] Therefore, it is necessary to provide a new agricultural rice harvesting device to solve the above-mentioned technical problems. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, an agricultural rice harvesting device is provided to solve the above-mentioned problems.

[0005] The agricultural rice harvesting equipment provided by this invention includes: a harvesting platform; a rice-supporting frame installed on the top of the harvesting platform, a transmission rod rotatably installed on the side of the rice-supporting frame away from the harvesting platform, and multiple rice-supporting poles arranged around the transmission rod, the multiple rice-supporting poles being spaced apart along the axial direction of the transmission rod; wherein, at both ends of the outer side of the transmission rod, there are adjustable distance components, the adjustable distance components being connected to the rice-supporting frame and the transmission rod respectively, for adjusting the height of the transmission rod relative to the harvesting platform, so as to change the distance between the rice-supporting poles and the ground; a cutting component is provided on the side of the harvesting platform near the transmission rod, below the transmission rod, the cutting component being used to cut the rice after it has been supported by the rice-supporting poles; a guide component is provided inside the harvesting platform on the side away from the cutting component, the guide component being used to guide and transport the cut rice to the rear of the harvesting platform.

[0006] Preferably, the pitch adjustment assembly includes a pitch adjustment box mounted on the outside of the transmission rod, a guide bracket installed inside the pitch adjustment box, and multiple telescopic rods slidably connected to the guide bracket. Each telescopic rod passes through the pitch adjustment box and is connected to a fixed seat on the side away from the center of the pitch adjustment box, and the outside of the supporting rod is mounted on the inside of the fixed seat.

[0007] Preferably, an adjusting disk is rotatably connected to one side of the guide bracket. The adjusting disk has multiple arc-shaped guide grooves, and a guide rod is provided in each arc-shaped guide groove. The side of each guide rod near the guide bracket is connected to the bottom of one side of the telescopic rod.

[0008] Preferably, a gear ring is installed on the outer side of the adjusting disk, a gear is meshed on one side of the gear ring, and one side of the gear is rotatably connected to the guide bracket. A connecting shaft is provided between the two adjusting boxes, and the two ends of the connecting shaft pass through the adjusting boxes and are respectively connected to the two gears. A first electric motor for driving the gear to rotate is installed on one side of the adjusting disk.

[0009] Preferably, the cutting assembly includes a plurality of cutting blades equidistantly mounted on one side of the harvesting table. The cutting blades are triangular in structure and have blades on their edges. A diverting block is mounted on the side of the cutting blades away from the harvesting table.

[0010] Preferably, the guiding assembly includes a guide roller rotatably connected to the harvesting table, with a first helical blade installed at one end of the outer side of the guide roller and a second helical blade installed at the other end, the first helical blade and the second helical blade being arranged opposite to each other.

[0011] Preferably, multiple rice-pulling stalks are installed at equal intervals on the outer side of the guide roller between the first and second helical blades.

[0012] Preferably, a synchronous pulley is installed at the same end of the transmission rod and the guide roller, and the two synchronous pulleys are connected by a synchronous belt drive. A protective cover is installed on one side of the harvesting table outside the two synchronous pulleys, and a second motor for driving one of the synchronous pulleys to rotate is installed on one side of the protective cover.

[0013] Preferably, each of the straw-lifting stalks has multiple straw-lifting teeth installed at equal intervals at its bottom.

[0014] Compared with related technologies, the rice harvesting equipment for agricultural production provided by this invention has the following beneficial effects: This invention, through the flexible adjustment of the spacing component, allows the height of the rice stalks to be adjusted according to the actual growth height and lodging degree of the rice. Whether it's rice growing upright normally or lodged due to wind and rain, it ensures the stalk-supporting mechanism is always in the optimal working position, effectively guiding and straightening the rice plants. Secondly, this design significantly improves the quality and efficiency of harvesting operations. The optimized stalk-supporting effect creates favorable conditions for subsequent cutting operations, allowing the rice straw to enter the cutting area in a neat posture. This not only ensures the flatness of the cut surface and reduces power loss, but also effectively reduces the occurrence of missed cuts from the source, thereby improving overall harvesting efficiency and quality.

[0015] The guiding component of this invention achieves stable and efficient transport of cut rice through the synergistic mechanism of spirals and conveying. When the guide roller rotates, the opposing spiral blades at both ends generate a centripetal conveying effect, continuously gathering the rice plants dispersed on both sides of the harvesting platform towards the central area, effectively preventing material scattering and accumulation at the platform edges. Simultaneously, multiple rice-pulling rods evenly distributed in the middle section of the roller generate a continuous axial propulsion force through rotation, complementing the spiral blades and jointly ensuring that the rice plants move towards the rear transport area with uniform density and speed.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0019] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0020] This invention provides an agricultural rice harvesting device, comprising: a harvesting platform 1; a rice-supporting frame 11 mounted on the top of the harvesting platform 1, a transmission rod 12 rotatably mounted on the side of the rice-supporting frame 11 away from the harvesting platform 1, and multiple rice-supporting poles 13 arranged around the transmission rod 12, the multiple rice-supporting poles 13 being spaced apart along the axial direction of the transmission rod 12; wherein, at both ends of the outer side of the transmission rod 12, there are adjustable distance components, which are respectively connected to the rice-supporting frame 11 and the transmission rod 12, for adjusting the height of the transmission rod 12 relative to the harvesting platform 1, so as to change the distance between the rice-supporting poles 13 and the ground; a cutting component is provided on the side of the harvesting platform 1 near the transmission rod 12, below the transmission rod 12, the cutting component being used to cut the rice after it has been supported by the rice-supporting poles 13; a guide component is provided inside the harvesting platform 1 on the side away from the cutting component, the guide component being used to guide and transport the cut rice to the rear of the harvesting platform 1, and multiple rice-supporting teeth are equally spaced at the bottom of each rice-supporting pole 13.

[0021] It should be noted that the harvesting platform 1 serves as the basic support and operating platform for the entire machine, and a rice-supporting frame 11 is installed on its top. A transmission rod 12 is rotatably mounted on the side of the rice-supporting frame 11 away from the harvesting platform 1. Multiple rice-supporting poles 13 are spaced axially along the periphery of the transmission rod 12, and each rice-supporting pole 13 has multiple rice-supporting teeth evenly spaced at its bottom. Driven by the transmission rod 12, the rice-supporting poles 13 and the rice-supporting teeth work together to effectively straighten and support the rice plants, preventing lodging or scattering, and ensuring the plants maintain a neat posture before cutting. Adjustment components are installed at both ends of the outer side of the transmission rod 12. These components are connected to the rice-supporting frame 11 and the transmission rod 12 respectively, and are used to adjust the height of the transmission rod 12 relative to the harvesting platform 1, thereby changing the distance between the rice-supporting poles 13 and the ground. This structure allows the equipment to flexibly adapt to rice crops of different heights or degrees of lodging, improving its adaptability to different field conditions. A cutting component is installed on the side of the harvesting platform 1 near and below the transmission rod 12. This component is used to cut the rice plants after they have been prepared by the rice-lifting mechanism. The cutting component has a high-efficiency cutting capability, ensuring a clean cut surface for the straw and reducing energy loss and straw breakage. Inside the harvesting platform 1, on the side away from the cutting component, a guide component is installed. Its function is to guide and transport the cut rice plants to the rear of the harvesting platform in an orderly manner, facilitating subsequent collection, threshing, or baling processes, and ensuring the continuity of the harvesting process and overall operational efficiency.

[0022] In an embodiment of the present invention, the pitch adjustment assembly includes a pitch adjustment box 2 mounted on the outside of the transmission rod 12. A guide bracket 21 is installed inside the pitch adjustment box 2. Multiple telescopic rods 22 are slidably connected to the guide bracket 21. Each telescopic rod 22 passes through the pitch adjustment box 2 on the side away from the center of the pitch adjustment box 2 and is connected to a fixed seat 23. The outside of the supporting rod 13 is mounted on the inside of the fixed seat 23. A pitch adjustment disk 24 is rotatably connected to one side of the guide bracket 21. Multiple arc-shaped guide grooves 25 are formed on the pitch adjustment disk 24. Each arc-shaped guide groove 25 contains... Each is equipped with a guide rod 26. The side of each guide rod 26 near the guide bracket 21 is connected to the bottom of one side of the telescopic rod 22. A gear ring 27 is installed on the outer side of the adjusting disk 24. A gear 28 is meshed on one side of the gear ring 27. One side of the gear 28 is rotatably connected to the guide bracket 21. A connecting shaft 29 is provided between the two adjusting boxes 2. The two ends of the connecting shaft 29 pass through the adjusting box 2 and are connected to the two gears 28 respectively. A first motor for driving the gears 28 to rotate is installed on one side of the adjusting disk 24.

[0023] It should be noted that the adjustable distance assembly mainly includes an adjustable distance box 2 installed on the outside of the transmission rod 12. The adjustable distance box 2 serves as the load-bearing and protective shell of the overall structure, providing stable installation space for the internal functional components while effectively isolating external debris and impacts, ensuring long-term reliable operation of the mechanism. A guide bracket 21 is fixedly installed inside the adjustable distance box 2. This bracket not only serves as a structural support but also provides precise sliding guidance for the multiple telescopic rods 22. The multiple telescopic rods 22 are arranged radially along the guide bracket 21 and form a sliding fit with it, ensuring that each telescopic rod 22 can move smoothly along a predetermined trajectory. The end of each telescopic rod 22 away from the central axis of the adjustable distance box 2 penetrates the side wall of the adjustable distance box 2 and is connected to a fixed seat 23 at its outer end. The outer side of the lifting rod 13 is installed inside the fixed seat 23. Through this connection method, the linear movement of the telescopic rod 22 can be directly converted into the radial displacement of the lifting rod 13, thereby realizing the adjustment of the distance between the lifting rod 13 and the ground. To achieve synchronous linkage of multiple telescopic rods 22, an adjusting disk 24 is rotatably connected to one side of the guide bracket 21. The adjusting disk 24 has multiple arc-shaped guide grooves 25, each containing a guide rod 26 that can slide along the groove. The end of each guide rod 26 near the guide bracket 21 is laterally connected to the bottom of the corresponding telescopic rod 22. When the adjusting disk 24 rotates around its axis, the rotational motion is converted into radial movement of the guide rod 26 through the interaction of the arc-shaped guide grooves 25 and the guide rods 26, thereby pushing the telescopic rod 22 to slide along the guide bracket 21. To drive the adjusting disk 24 to rotate, a gear ring 27 is installed on its outer side, which meshes with a gear 28. The gear 28 is rotatably connected to the guide bracket 21 via a bearing structure, ensuring smooth and reliable transmission. A connecting shaft 29 is provided between the two adjusting boxes 2, with both ends of the connecting shaft 29 penetrating the walls of the corresponding adjusting boxes 2 and connecting to the gears 28 inside the boxes, ensuring synchronous movement of the adjusting mechanisms on both sides. A first electric motor installed on one side of the adjusting disc 24 serves as the power source. It drives the gear 28 to rotate, transmitting the power through the gear ring 27 to the adjusting disc 24, ultimately achieving synchronous telescopic adjustment of all telescopic rods 22. When the working height of the lifting rod 13 needs adjustment, the first electric motor starts and drives the gear 28 to rotate. The gear 28, through meshing with the gear ring 27, drives the adjusting disc 24 to rotate. The connecting shaft 29 between the two adjusting boxes 2 ensures the synchronous rotation of the gears 28 on both sides, allowing the adjusting discs 24 on both sides to rotate completely synchronously. The rotating adjusting disc 24 applies force to the guide rod 26 through its arc-shaped guide groove 25, forcing the guide rod 26 to move along the groove trajectory. This movement, through the connection between the guide rod 26 and the telescopic rod 22, converts the rotational motion of the adjusting disc 24 into radial linear motion of the telescopic rod 22 on the guide bracket 21. All telescopic poles 22 move synchronously under the drive of the adjusting disc 24, causing the fixed base 23 and the supporting poles 13 installed on it to rise and fall in unison, thereby achieving precise and synchronous adjustment of the distance between the supporting poles 13 and the ground. In an embodiment of the present invention, the cutting assembly includes a plurality of cutting blades 3 equidistantly mounted on one side of the harvesting table 1. The cutting blades 3 are triangular in structure and have blades on their edges. A diverting block 31 is mounted on the side of the cutting blades 3 away from the harvesting table 1.

[0024] It should be noted that the multiple cutting blades 3, which are equidistant from one side of the harvesting table 1, are the core components for cutting rice. Their triangular structure optimizes the force distribution and improves cutting stability, while the edge-set blades enhance the cutting sharpness, ensuring that the rice straw after being stalked by the supporting stalks 13 is cut quickly and neatly. At the same time, the diversion block 31 installed on the side of the cutting blades 3 away from the harvesting table 1 can divert and guide the rice plants to be cut during the cutting operation, avoiding the accumulation and congestion of rice near the cutting blades 3, ensuring that the cutting blades 3 can continuously and efficiently carry out the cutting operation, and creating good conditions for the subsequent guiding components to transport the cut rice.

[0025] In an embodiment of the present invention, the guiding assembly includes a guide roller 4 rotatably connected to the harvesting platform 1. A first helical blade 41 is installed at one end of the outer side of the guide roller 4, and a second helical blade 42 is installed at the other end. The first helical blade 41 and the second helical blade 42 are arranged opposite to each other. A plurality of rice stalks 43 are equidistantly installed on the outer side of the guide roller 4 between the first helical blade 41 and the second helical blade 42. A synchronous pulley is installed at the same end of the transmission rod 12 and the guide roller 4. The two synchronous pulleys are connected by a synchronous belt drive. A protective cover is installed on one side of the harvesting platform 1 outside the two synchronous pulleys. A second electric motor for driving one of the synchronous pulleys to rotate is installed on one side of the protective cover.

[0026] It should be noted that: in the guiding assembly, the guide roller 4, which is rotatably connected to the harvesting table 1, is the core load-bearing component for guiding and conveying rice. The first spiral blade 41 installed at one end and the second spiral blade 42 installed at the other end are arranged oppositely. When the guide roller 4 rotates, they gather the cut rice from both sides of the harvesting table 1 towards the center, preventing the rice from scattering to the edge of the harvesting table 1 during conveying. Multiple rice-pulling rods 43, equidistantly installed between the first spiral blade 41 and the second spiral blade 42 on the outer side of the guide roller 4, further assist in pushing the rice towards the rear of the harvesting table 1, preventing the rice from accumulating and jamming on the surface of the guide roller 4, and ensuring continuous conveying. Synchronous pulleys installed at the same end of the transmission rod 12 and the guide roller 4, as well as the synchronous belt connecting the two synchronous pulleys, enable synchronous rotation of the transmission rod 12 and the guide roller 4, ensuring coordinated and consistent rice-lifting and guiding / conveying actions. The harvesting table 1... A protective cover installed on one side outside the two synchronous pulleys prevents impurities from entering the transmission gap between the synchronous pulleys and the synchronous belt, and also prevents personnel from accidentally touching the transmission components during operation, thus providing protection. A second motor installed on one side of the protective cover provides power for the rotation of the guide roller 4. By driving one of the synchronous pulleys to rotate, the synchronous belt drives the other synchronous pulley and the guide roller 4 to rotate synchronously, ultimately achieving stable guidance and conveying of the cut rice to the rear of the harvesting platform 1. After the second motor starts, it drives the synchronous pulley connected to it to rotate, and the power is transmitted to the other synchronous pulley through the synchronous belt, driving the guide roller 4 to rotate continuously. Because the transmission rod 12 and the guide roller 4 are linked by synchronous pulleys and synchronous belts, the sorting action of the rice-lifting mechanism and the guiding and conveying speed remain coordinated. During the rotation of the guide roller 4, the first spiral blade 41 and the second spiral blade 42 at both ends act as the main gathering mechanism, continuously pushing the cut rice scattered on both sides of the harvesting platform towards the central area; simultaneously, multiple rice-pulling stalks 43 located in the middle act as an auxiliary propulsion mechanism, steadily and continuously advancing the gathered material to the rear conveying area through contact with the rice stalks. This combined effect of spiral gathering and conveying ensures a smooth transition of rice from the cutting area to subsequent processes, forming a continuous and uninterrupted flow of materials.

[0027] The working principle of the rice harvesting equipment for agricultural production provided by this invention is as follows: During operation, the equipment moves forward under power drive. First, based on the growth height and lodging condition of the rice, the rice-lifting mechanism is precisely adjusted through the adjusting component: the first motor starts, driving the gear 28 to rotate, which in turn drives the gear ring 27 and the adjusting plate 24 to rotate. The arc-shaped guide groove 25 on the adjusting plate controls the telescopic rod 22 to slide along the guide bracket 21 through the guide rod 26, and finally achieves precise adjustment of the height of the rice-lifting rod 13 through the fixed seat 23. This adjustable structure enables the equipment to significantly improve its adaptability to different field conditions, effectively cope with rice in different growth stages, and lay the foundation for subsequent operations. After the rice-lifting height is adjusted, the transmission rod 12 drives the rice-lifting rod 13 to rotate. The rice-lifting rod and the rice-lifting teeth at its bottom orderly lift the rice plants and guide them to the cutting area. This process effectively improves the rice-lifting effect, keeps the plants in a neat posture, and creates ideal conditions for efficient cutting. During the cutting process, the high-speed rotating cutting blade 3 utilizes its specially designed triangular structure and sharp blades to quickly and neatly cut the rice straw. Simultaneously, the diverting block 31 effectively diverts the rice plants, significantly reducing blockages and entanglement, ensuring continuous and smooth cutting operations. This design not only improves cutting efficiency but also effectively reduces the missed cutting rate by optimizing cutting quality. The cut rice is then conveyed in an orderly manner under the guidance of the guiding assembly. The guide roller 4 rotates under the drive of a second motor, with its opposing first and second helical blades 41 and 42 converging the rice from both sides towards the center, while the rice stalks 43 continuously push the rice backward. Since the transmission rod 12 and the guide roller 4 rotate synchronously via synchronous pulleys and belts, coordination between each process is ensured. This composite conveying mechanism effectively prevents material blockage and spillage, ensuring the continuity and stability of the entire harvesting process.
