Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a rice threshing device with a drying function. Background Technology

[0002] Rice is one of the world's most important food crops. With the continuous development of agricultural mechanization, the harvesting and threshing of rice have gradually become automated. While traditional rice threshing equipment can complete the threshing task, it often suffers from low threshing efficiency and poor threshing quality, especially with different rice varieties and maturity levels, making it difficult to maintain consistent threshing results. To improve threshing efficiency and quality, researchers have continuously improved and optimized automated rice threshing equipment.

[0003] Most existing rice threshing equipment uses a single threshing method such as crushing, extrusion, or vibrating screening. However, current technologies often fail to achieve efficient and uniform threshing results for different rice varieties and maturity levels. For example, the threshing force of some equipment is not adjustable, leading to damage to some grains or incomplete threshing, affecting threshing quality. Simultaneously, the waste removal and equipment cleaning systems of existing equipment are relatively simple, easily leading to waste accumulation or equipment blockage, thus affecting the continuous and efficient operation of the equipment. Furthermore, during the threshing process, the separation of rice and waste is not thorough enough, resulting in a high impurity content, affecting the purity of the rice and collection efficiency.

[0004] The main problem with existing technologies in rice threshing is that the threshing effect cannot be precisely adjusted according to different rice varieties and maturity levels. Especially when the humidity is high, the threshing process is often obstructed, resulting in low threshing efficiency or equipment blockage. This problem directly affects the working efficiency and threshing quality of the equipment. In particular, when the rice is in high humidity, traditional equipment is difficult to achieve the ideal threshing effect, thereby reducing the overall efficiency of the threshing operation.

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0034] Please see the appendix Figure 1 -Appendix Figure 6 This invention provides a rice threshing device with a drying function, comprising:

[0035] The crushing component is used to initially separate the harvested rice to facilitate subsequent threshing operations;

[0036] The extrusion assembly can automatically flip the rice to be threshed, achieving double-sided threshing.

[0037] The drying unit is used to remove waste and dust generated during the threshing process and to dry the threshed rice through heating.

[0038] The drive assembly is used to drive the crushing assembly and the telescopic assembly to operate synchronously, ensuring that the threshing process is carried out efficiently.

[0039] The screening component separates the threshed rice from the waste generated during the threshing process, achieving further separation of materials.

[0040] The telescopic assembly includes a housing 1, with a crushing box 2 fixedly connected to the upper surface of the housing 1. A screening screen 28 is installed inside the housing 1. A rotating shaft 12 is rotatably connected inside the housing 1. A second connecting sleeve 17 is fixedly connected to the outer wall of the rotating shaft 12. A first connecting sleeve 15 is fixedly connected to the outer wall of the second connecting sleeve 17. A first hydraulic rod 13 is fixedly connected inside the second connecting sleeve 17. The output end of the first hydraulic rod 13 is fixedly connected to one side of the outer wall of a moving block 14. A moving plate 16 is fixedly connected to the outer wall of the moving block 14. The outer wall of the first connecting sleeve 15 is rotatably connected to a support rod 18. One end of the support rod 18 is rotatably connected to a slider 19. The inner wall of the slider 19 is slidably connected to a guide rail 20. One side of the outer wall of the guide rail 20 is fixedly connected to a fixed disk 21. The inner wall of the fixed disk 21 is fixedly connected to the outer wall of the first connecting sleeve 15. The outer wall of the slider 19 is fixedly connected to a broken blade 23. The inner walls of the first connecting sleeve 15 and the second connecting sleeve 17 are both provided with grooves 22. The outer wall of the support rod 18 is slidably connected to the inner wall of the groove 22, driving the broken blade 23 to extend and retract.

[0041] In one embodiment, the hydraulic system controls the extension and retraction of the crushed leaf blades 23 via a first hydraulic rod 13 and a second hydraulic rod 25. The first hydraulic rod 13 is located inside the second connecting sleeve 17. Hydraulic drive causes the hydraulic rod to move along a predetermined track inside the housing 1. When the hydraulic system is activated, the first hydraulic rod 13 pushes the moving block 14 to move, thereby causing the connected moving plate 16 to extend and retract. The outer wall of the moving plate 16 is connected to the slider 19 via a support rod 18. The slider slides on the guide rail 20, thereby precisely adjusting the entire extension and retraction assembly. During the extension and retraction process, the crushed leaf blades 23 fixed on the slider 19 are displaced according to the extension and retraction amplitude, thus adjusting the working position of the crushing assembly. The extension and retraction of the crushed leaf blades can flexibly adjust the threshing force and range according to the different threshing requirements of rice, ensuring the best threshing effect for each rice plant. The support rod 18 in the telescopic assembly is slidably connected to the outer wall of the groove 22. The sliding of the support rod 18 in conjunction with the design of the groove 22 makes the telescopic assembly's extension and retraction smoother and more stable. Simultaneously, the guide rail 20 and the slider 19 cooperate to ensure the precision of the extension and retraction, avoiding operational instability caused by over-extension or misalignment. The design of the telescopic assembly allows the crushed rice blades 23 to be precisely adjusted according to different threshing requirements. When the rice variety or maturity changes, the telescopic assembly can automatically or manually adjust the position of the crushed rice blades to ensure the optimal balance between threshing force and speed. This process helps improve the threshing efficiency of the equipment and reduce damage to the rice.

[0042] The drive assembly includes a connecting ring 5, with a belt 6 fitted on the outer wall of the connecting ring 5. A first motor 11 is fixedly connected to one side of the outer wall of the crushing box 2, and the output end of the first motor 11 is fixedly connected to the inside of the connecting ring 5.

[0043] In one embodiment, the core component of the drive assembly is a first motor 11, which generates torque through electric drive. The first motor 11 is fixedly installed on one side of the outer wall of the crushing box 2. After the motor starts, its output end is connected to the belt 6 through a connecting ring 5 to transmit power. The connecting ring 5 is sleeved on the outer wall of the belt 6, and the belt 6 transmits power from the first motor 11 to other mechanical components through friction. As an efficient power transmission method, the belt 6 can smoothly transmit the rotational motion of the first motor 11 to the crushing box 2 and related components, ensuring its smooth operation. The design of the drive assembly ensures the synchronous operation of the crushing box 2 and other components. Under the drive of the first motor 11, the crushing roller 39 and crushing disc 38 in the crushing box 2 operate simultaneously, further ensuring the efficient separation of rice during the threshing process. The belt 6 drive enables multiple operation steps such as crushing and screening to be completed in a coordinated manner, improving the overall performance of the equipment.

[0044] The crushing assembly includes a crushing box 2, with crushing discs 38 fixedly connected inside the crushing box 2 and a crushing roller 39 rotatably connected inside the crushing box 2. A first gear 8 is fixedly connected to one end of the crushing roller 39, and a second gear 37 is rotatably connected to one side of the outer wall of the crushing box 2. The second gear 37 meshes with the first gear 8, and the output end of the first motor 11 is fixedly connected to the inside of the second gear 37. The crushing roller 39 meshes with the crushing discs 38.

[0045] In one embodiment, the crushing assembly is powered by a first motor 11, which is connected to a second gear 37 via its output end, driving the second gear 37 to rotate. The second gear 37 meshes with a first gear 8, causing the first gear 8 to drive the crushing roller 39 to rotate. The crushing roller 39 and the crushing discs 38 are the core components of the crushing assembly. When the first motor 11 starts, power is transmitted to the crushing roller 39 through the gear system. As the crushing roller 39 rotates, it interacts with the crushing discs 38 fixed inside the crushing chamber 2. The rice is clamped and subjected to mechanical impact, thus achieving initial crushing. The meshing of the crushing roller 39 and the crushing discs 38 generates strong friction and impact forces, effectively separating the rice husk from the grains. The rotational motion of the crushing roller ensures that the rice is subjected to uniform force during the crushing process, avoiding uneven or over-crushing. The first gear 8 and the second gear 37 ensure the smooth rotation of the crushing roller. The rotation of the crushing roller 39 drives the crushing discs 38 to achieve maximum efficiency, thereby achieving the desired crushing effect.

[0046] The extrusion assembly includes a fixed plate 3, a connecting plate 4 slidably connected to the lower surface of the fixed plate 3, an extrusion plate 27 fixedly connected to the lower surface of the connecting plate 4, a second hydraulic rod 25 fixedly connected to the outer wall of the fixed plate 3, a crossbar 26 fixedly connected to the outlet end of the second hydraulic rod 25, a groove is provided inside the crushing box 2, and the inner wall of the crossbar 26 is slidably connected to the inner wall of the groove.

[0047] In one embodiment, the extrusion assembly is powered by a second hydraulic rod 25, the output end of which is connected to a fixed plate 3 via a crossbar 26. When the second hydraulic rod 25 is activated, the hydraulic action pushes the crossbar 26 to slide along the groove 2, thereby causing the fixed plate 3 and the connecting plate 4 to slide. The fixed plate 3 and the connecting plate 4 are slidably connected, with the lower surface of the fixed plate 3 slidably connected to the connecting plate 4. The crossbar 26 pushes the connecting plate 4 to move, which in turn causes the extrusion plate 27 to move as well, thus generating an extrusion action. Through the movement of the extrusion plate 27, the rice is flipped during the extrusion process, ensuring that both sides of the rice are subjected to uniform extrusion. This double-sided extrusion process effectively improves the threshing efficiency and avoids the uneven threshing that may be caused by single-sided extrusion. The crossbar 26 achieves automatic adjustment of the extrusion plate 27 by sliding within the groove. The position of the extrusion plate 27 can be precisely adjusted according to the different types and thicknesses of rice, thereby ensuring the best extrusion effect of the rice during the threshing process.

[0048] The cleaning assembly includes a support frame 9, with a hot air blower 10 fixedly connected to the upper surface of the support frame 9, and a connecting pipe 24 fixedly connected to the output end of the hot air blower 10.

[0049] In one embodiment, the drying assembly includes a support frame 9 and a hot air blower 10 fixed to the support frame. When the hot air blower 10 is started, a powerful airflow is generated by its internal fan. The airflow generated by the hot air blower 10 is conducted through a connecting pipe 24, which guides the airflow to key parts of the equipment, especially the waste and dust areas during the threshing process. The design of the connecting pipe 24 allows the airflow to cover all parts of the equipment, ensuring effective cleaning. The airflow is delivered to the threshing chamber and other working areas through the connecting pipe 24, helping to remove dust and debris generated during the threshing process, ensuring smooth material flow through each component, and preventing waste accumulation from affecting the normal operation of the equipment. The drying and cleaning assembly, through the hot airflow generated by the hot air blower, not only removes waste and dust generated during the threshing process but also accelerates the drying process of the rice. The design of the connecting pipe 24 ensures that the airflow is evenly distributed to the threshing chamber and related working areas, and the path of the airflow ensures that waste and dust are thoroughly cleaned, preventing them from affecting the normal operation of the equipment. In addition, the airflow of the hot air blower 10 not only helps to clean the material but also effectively reduces the moisture content of the threshed rice, improving the storage quality of the rice.

[0050] The screening assembly includes a storage box 30, a fixed frame 31 is fixedly connected to the outer wall of the storage box 30, a second motor 32 is fixed to the upper surface of the fixed frame 31, an eccentric wheel 33 is fixedly connected to the output end of the second motor 32, a fixed rod 34 is rotatably connected to the outer wall of the eccentric wheel 33, a rotating rod 35 is rotatably connected inside the fixed rod 34, a connecting rod 36 is fixedly connected to one end of the rotating rod 35, and one side of the outer wall of the connecting rod 36 is fixedly connected to the outer wall of the screen plate 40.

[0051] In one embodiment, the motor drives the eccentric wheel 33 to rotate via its output end. The second motor continuously provides power to ensure stable screening. The outer wall of the eccentric wheel 33 is connected to the fixed rod 34, and the rotation of the eccentric wheel 33 drives the fixed rod 34 to reciprocate. Due to the structural design of the eccentric wheel 33, it generates periodic vibrations when rotating, which in turn causes the movement of subsequent components. The fixed rod 34 is connected to the connecting rod 36 via a rotating rod 35. One end of the rotating rod 35 is fixedly connected to the connecting rod 36, and the other end of the connecting rod 36 is connected to the screen plate 40. The rotation of the rotating rod ensures coordinated movement of the entire screening assembly, guaranteeing stable screening results. Throughout the screening process, the screening mesh inside the screen plate 40 physically separates the threshed rice from the waste. The vibration generated by the eccentric wheel 33 is transmitted to the screening box 30 via the rotating rod and the connecting rod 36, causing the screen to separate the rice and waste through continuous vibration. Lighter waste is ejected by vibration, while heavier rice remains in the screening box, completing the separation.

[0052] The connecting pipe 24 is located inside the box 1 and is positioned higher than the screening screen 28. The box 1 has a slag outlet 7. A guide plate 29 is fixedly connected to the lower part of the box 1. The guide plate 29 is located above the screen plate 40 to facilitate material discharge. The outer wall of the first connecting sleeve 15 is rotatably connected to the inside of the box 1.

[0053] In one embodiment, the connecting pipe 24 is located inside the housing 1 and is positioned above the screening screen 28. This design allows waste and impurities generated during the screening process to flow smoothly through the connecting pipe to the designated discharge area. Because the connecting pipe is positioned higher than the screening screen, materials and waste are more easily guided to the slag outlet 7, avoiding blockage or accumulation and ensuring timely discharge of waste. The slag outlet 7 inside the housing 1 is connected to the connecting pipe 24, forming a waste discharge channel. During the screening process, waste is separated through the screening screen and then discharged through the slag outlet 7. The design of the slag outlet allows waste to be discharged from the housing efficiently, avoiding waste accumulation, reducing interference with the equipment, and ensuring long-term stable operation of the equipment. A guide plate 29 is fixedly connected to the lower part of the housing 1. The guide plate is located above the screen plate 40. The guide plate not only helps the waste to be discharged smoothly but also guides the flow of materials, ensuring an orderly discharge process. The reasonable position and structural design of the guide plate improves the material guiding efficiency, so that the threshed rice will not be stuck during the screening process, reducing the risk of blockage. The first connecting sleeve 15 is rotatably connected to the inside of the housing 1 through the outer wall, allowing flexible relative movement between the telescopic component and the screening component. This design ensures smooth operation of the entire threshing unit, preventing jamming or resistance caused by component friction. The rotating connection facilitates smoother material conveying and waste discharge, enhancing overall operational flexibility.

[0054] Working Principle: First, the crushing assembly initially separates the harvested rice. Rice enters the crushing chamber through the feed inlet. The crushing rollers and crushing blades rotate and mesh with each other, initially separating the rice husk from the grain. The design of the crushing rollers and crushing blades takes into account the structural characteristics of different rice varieties, effectively destroying the integrity of the rice husk and facilitating subsequent threshing. Next, the initially crushed rice enters the extrusion assembly, which uses a hydraulic control system to extrude the rice on both sides. The cooperation of the extrusion plate and connecting plate allows the rice to be threshed to automatically rotate, ensuring full grain removal. During this process, the movement of the extrusion plate is driven by hydraulic rods and can be adjusted according to different rice varieties and threshing requirements to ensure optimal threshing results. To meet the processing needs of different rice types, the telescopic assembly plays a crucial role. By adjusting the gap between the crushing blades and the screening screen, the telescopic assembly flexibly adapts to different sizes and varieties of rice, ensuring that each batch of rice achieves the best threshing effect. The telescopic assembly consists of a housing, a rotating shaft, hydraulic rods, moving blocks, and support rods. The hydraulic system can adjust the distance between the crushed rice blades and the screen in real time, helping the equipment adapt to different workloads and rice characteristics. The core of the telescopic assembly is to optimize the threshing effect by driving the telescopic adjustment of the crushed rice blades. The drying assembly is mainly responsible for removing waste, dust, and other impurities generated during the threshing process, ensuring the cleanliness and normal operation of the equipment. When the hot air blower starts, it raises the air temperature through its heated airflow, quickly evaporating the moisture in the rice and preventing the rice from becoming moldy or fermenting due to prolonged exposure to moisture. The temperature and humidity of the airflow can be adjusted as needed to ensure that the rice is dried within the optimal temperature range, avoiding over-drying or scorching. The hot air blower blows out waste and dust through the connecting pipe, preventing them from accumulating inside the equipment and affecting threshing efficiency and long-term use. The design of the hot air blower and connecting pipe ensures a more uniform airflow distribution, so that the airflow not only cleans up the dust and impurities generated after threshing but also covers the surface of the rice, allowing moisture to evaporate evenly in each grain of rice after threshing. The design of the connecting pipe allows for flexible adjustment of the airflow direction, ensuring no dead zones or poor air circulation, thereby improving drying efficiency. This design ensures that the equipment can maintain high efficiency under long-term high-load operation. The drive component provides power support for the entire system, ensuring the coordinated work of each component. The drive component drives the connecting ring through a motor and belt, realizing the synchronous operation of multiple important parts such as the crushing box, extrusion plate, crushing roller, and screening component.Precise control of the drive system can effectively reduce the power consumption of the equipment, improve work efficiency, and ensure stability during the threshing process. Finally, the screening component is responsible for separating the threshed rice from the waste. The screening screen is located inside the equipment. After vibration and screening, the rice and waste are effectively separated. The screening component is driven by a motor to drive the eccentric wheel, which drives the screening screen to vibrate and further separate impurities. The screened rice is stored in the storage box to ensure the purity and collection of the grains. The whole process is seamless and improves production efficiency.
