Description

Although traditional rice threshing equipment can complete the threshing task, it often has problems such as low threshing efficiency and poor threshing quality, especially under different rice varieties and maturity, the threshing effect is difficult to maintain consistency. In order to improve threshing efficiency and quality, researchers have continuously improved and optimized rice automatic threshing equipment.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Please see attached Figure 1 -Attached Figure 6 The embodiment of the present invention provides a rice threshing device with a drying function, comprising:

[0035] A breaking assembly for initially separating the harvested rice to facilitate subsequent threshing operations;

[0036] The extrusion component can automatically turn over the rice to be threshed to achieve the function of double-sided threshing;

[0039] The screening component screens the threshed rice and the waste generated during the threshing process to achieve further separation of the materials.

[0040] The telescopic assembly includes a box body 1, the upper surface of the box body 1 is fixedly connected to a crushing box 2, the interior of the box body 1 is provided with a screening net 28, the interior of the box body 1 is rotatably connected to a rotating shaft 12, the outer wall of the rotating shaft 12 is fixedly connected to a second connecting sleeve 17, the outer wall of the second connecting sleeve 17 is fixedly connected to a first connecting sleeve 15, the interior of the second connecting sleeve 17 is fixedly connected to a first hydraulic rod 13, the output end of the first hydraulic rod 13 is fixedly connected to one side of the outer wall of a moving block 14, the outer wall of the moving block 14 is fixedly connected to a moving plate 16, the moving plate 16 The outer wall of the slider 19 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 crushing leaf 23, the first connecting sleeve 15 and the second connecting sleeve 17 are both provided with a slide groove 22, the outer wall of the support rod 18 is slidably connected to the inner wall of the slide groove 22, driving the crushing leaf 23 to perform telescopic adjustment.

[0041] In one embodiment, the hydraulic system controls the telescopic movement of the crushing leaf 23 through the first hydraulic rod 13 and the second hydraulic rod 25. The first hydraulic rod 13 is located inside the second connecting sleeve 17. The hydraulic drive enables the hydraulic rod to move along a predetermined track inside the box 1. When the hydraulic system is started, the first hydraulic rod 13 pushes the moving block 14 to move, thereby driving the moving plate 16 connected thereto to perform telescopic movement. The outer wall of the moving plate 16 is connected to the slider 19 through the support rod 18. The slider slides on the guide rail 20, thereby driving the entire telescopic assembly to be precisely adjusted.

The outer wall of the support rod 18 in the telescopic assembly is slidably connected to the slide groove 22. The design of the sliding of the support rod 18 and the slide groove 22 makes the telescopic action of the telescopic assembly smoother and more stable. At the same time, the guide rail 20 cooperates with the slider 19 to ensure the accuracy of the telescopic action and avoid unstable operation caused by excessive telescopic or imbalance. The design of the telescopic assembly enables the crushing leaf 23 to be accurately adjusted according to different threshing requirements. When the rice variety or the maturity of the rice changes, the telescopic assembly can automatically or manually adjust the position of the crushing leaf to ensure the best balance between threshing force and speed. This process helps to improve the threshing efficiency of the equipment and reduce the damage to the rice.

[0042] The driving assembly includes a connecting ring 5 , an outer wall of which is sleeved with a belt 6 , a first motor 11 is fixedly connected to one side of the outer wall of the crushing box 2 , and an 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 driving assembly is the first motor 11, which generates a torque through electric drive. The first motor 11 is fixedly mounted on one side of the outer wall of the crushing box 2. After the motor is started, its output end is connected to the belt 6 through the connecting ring 5 to transmit power. The connecting ring 5 is sleeved on the outer wall of the belt 6. 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 to ensure their smooth operation. The design of the driving 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 the crushing sheet 38 in the crushing box 2 operate simultaneously, further ensuring the efficient separation of rice during the threshing process. The belt 6 transmission enables multiple operation steps such as crushing and screening to be completed in a coordinated manner, thereby improving the overall performance of the equipment.

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

[0045] In one embodiment, the crushing assembly is powered by the first motor 11, and the first motor 11 is connected to the second gear 37 through its output end to drive the second gear 37 to rotate. The second gear 37 is meshed with the first gear 8, so that the first gear 8 drives the crushing roller 39 to rotate. The crushing roller 39 and the crushing sheet 38 are the core components of the crushing assembly. When the first motor 11 is started, the power is transmitted to the crushing roller 39 through the gear system. When the crushing roller 39 rotates, it interacts with the crushing sheet 38 fixed in the crushing box 2, and the rice is clamped and mechanically impacted, thereby achieving preliminary crushing. The crushing roller 39 is meshed with the crushing sheet 38 to generate strong friction and impact force, effectively separating the rice husk from the rice grain. The rotation of the crushing roller ensures that the rice can be evenly stressed during the crushing process, avoiding uneven crushing 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 sheet 38 to maximize its efficiency, thereby achieving the expected crushing effect.

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

[0047] In one embodiment, the squeezing assembly is powered by a second hydraulic rod 25, and the output end of the hydraulic rod 25 is connected to the fixed plate 3 through a cross bar 26. When the second hydraulic rod 25 is activated, the hydraulic action pushes the cross bar 26 to slide along the groove 2, thereby driving the fixed plate 3 and the connecting plate 4 to slide. The fixed plate 3 is connected to the connecting plate 4 by sliding, and the lower surface of the fixed plate 3 is connected to the connecting plate 4 by sliding connection. The cross bar 26 pushes the connecting plate 4 to move, and then the squeezing plate 27 also moves accordingly, thereby generating a squeezing action. Through the movement of the squeezing plate 27, the rice is turned over during the squeezing process, ensuring that both sides of the rice can be squeezed evenly. This double-sided squeezing process effectively improves the threshing efficiency and avoids the uneven threshing that may be caused by single-sided squeezing. The cross bar 26 realizes the automatic adjustment of the squeezing plate 27 by sliding in the groove. According to different types and thicknesses of rice, the position of the squeezing plate 27 can be accurately adjusted, thereby ensuring the best squeezing effect of rice during the threshing process.

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

[0049] In one embodiment, the drying assembly includes a support frame 9 and a hot air blower 10 fixed on the support frame. When the hot air blower 10 is started, a strong airflow is generated by the fan inside it. The airflow generated by the hot air blower 10 is conducted through the connecting pipe 24. The connecting pipe 24 guides the airflow to the key parts of the equipment, especially the waste and dust areas in the threshing process. The design of the connecting pipe 24 enables the airflow to cover all parts of the equipment to ensure effective cleaning. The airflow is transported to the threshing box and other working areas through the connecting pipe 24 to help clean up the dust and debris generated by the threshing process, ensure that the material passes smoothly through each component, and avoid waste accumulation affecting the normal operation of the equipment. The drying and cleaning assembly is not only removed by the hot air flow generated by the hot air blower, but also can accelerate the drying process of rice through hot air. The design of the connecting pipe 24 ensures that the airflow can be evenly distributed to the threshing box and related working areas. The path through which the airflow passes can ensure that the waste and dust are thoroughly cleaned to avoid affecting the normal operation of the equipment. In addition, the airflow of the hot air blower 10 not only helps to clean up the material, but also effectively reduces the humidity of the rice after threshing and improves the storage quality of rice.

[0050] The screening component includes a storage box 30, the outer wall of the storage box 30 is fixedly connected to a fixing frame 31, the upper surface of the fixing frame 31 is fixed to a second motor 32, the output end of the second motor 32 is fixedly connected to an eccentric wheel 33, the outer wall of the eccentric wheel 33 is rotatably connected to a fixing rod 34, the inside of the fixing rod 34 is rotatably connected to a rotating rod 35, one end of the rotating rod 35 is fixedly connected to a connecting rod 36, 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 through its output end. The drive of the second motor continuously provides power to ensure that the screening process is carried out stably. 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, when it rotates, it will generate periodic vibration, which will cause the movement of the subsequent components. The fixed rod 34 is connected to the connecting rod 36 through the 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. Through the rotation of the rotating rod, the movement of the entire screening assembly is kept coordinated and consistent, ensuring the stability of the screening effect. During the entire screening process, the screening net 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 through the rotating rod and the connecting rod 36, so that the screen separates the rice and the waste in continuous vibration. The lighter waste is thrown out through vibration, while the heavier rice remains in the screening box, completing the separation.

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

[0053] In one embodiment, the connecting pipe 24 is located inside the box 1 and is higher than the screening net 28. This design allows the waste and impurities generated during the screening process to flow smoothly to the designated discharge area through the connecting pipe. Since the position of the connecting pipe is higher than the screening net, the material and waste are more easily guided to the slag outlet 7, avoiding blockage or accumulation, and ensuring that the waste can be discharged in time. The slag outlet 7 arranged in the box body 1 is connected to the connecting pipe 24 to form a waste discharge channel. During the screening process, the waste is separated through the screening net and then discharged through the slag outlet 7. The design of the slag outlet enables the waste to be efficiently discharged from the box body, avoiding the accumulation of waste, reducing interference with the equipment, and ensuring the long-term stable operation of the equipment. A guide plate 29 is fixedly connected to the lower part of the box body 1, and the guide plate is located above the screen plate 40. The setting of the guide plate not only helps to discharge the waste smoothly, but also guides the flow direction of the material to ensure that the discharge process is orderly. The reasonable position and structural design of the guide plate improve the guiding efficiency of the material, 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 box body 1 through the outer wall, allowing flexible relative movement between the telescopic component and the screening component. This design ensures that the entire threshing device operates smoothly during operation, avoiding jamming or resistance caused by component friction. The rotating connection makes the material conveying and waste discharge process smoother, improving the overall operational flexibility.

[0054] Working principle: First, the function of the crushing assembly is to perform preliminary separation of the harvested rice. The rice enters the crushing box through the feed port, and the crushing roller and the crushing sheet rotate and engage with each other to initially separate the rice husk from the grain. The design of the crushing roller and the crushing sheet takes into account the structural characteristics of different rice varieties, which can effectively destroy the integrity of the rice husk and facilitate the subsequent threshing. Next, the rice that has been initially crushed enters the extrusion assembly, which performs double-sided extrusion of the rice through a hydraulic control system. The cooperation of the extrusion plate and the connecting plate enables the rice to be threshed to automatically flip over to ensure that the grains are fully shed. In this process, the movement of the extrusion plate is driven by a hydraulic rod, which can be adjusted according to the different types of rice and threshing requirements to ensure the optimization of the threshing effect. In order to meet the processing requirements of different types of rice, the telescopic assembly plays an important role. The telescopic assembly flexibly adapts to rice of different sizes and types by adjusting the gap between the crushing leaf and the screening net to ensure that each batch of rice can achieve the best threshing effect. The telescopic component is composed of a box, a rotating shaft, a hydraulic rod, a moving block and a supporting rod. The hydraulic system can adjust the distance between the crushing leaf and the screen in real time to help the equipment adapt to different workloads and rice characteristics. The core of the telescopic component is to optimize the threshing effect by driving the telescopic adjustment of the crushing leaf. The drying component is mainly responsible for removing waste, dust and other impurities generated during the threshing process to ensure the cleanliness and normal operation of the equipment. When the hot air blower is started, the air temperature is increased by the air flow it heats, and the moisture in the rice is quickly evaporated to prevent the rice from becoming moldy or fermenting due to long-term exposure to moisture. The temperature and humidity of the air flow can be adjusted as needed to ensure that the rice is dried within the optimal temperature range to avoid over-drying or scorching. The hot air blower blows out the waste and dust through the connecting pipe to prevent them from accumulating inside the equipment, thereby affecting the threshing efficiency and the long-term use of the equipment. The design of the hot air blower and the connecting pipe ensures that the airflow is more evenly distributed, so that the airflow not only cleans up the dust and impurities generated after threshing, but also covers the surface of the rice, so that the moisture is evenly evaporated in each rice after threshing. The design of the connecting pipe allows the airflow to flexibly adjust its direction to ensure that there are no dead corners or poor air circulation, thereby improving the 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 to ensure the coordinated work of each component. The drive component drives the connecting ring through an electric motor and a belt to achieve the synchronous operation of multiple important parts such as the crushing box, extrusion plate, crushing roller, and screening component.The 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 net is located inside the equipment. After vibration and screening, the rice and waste are effectively separated. The screening component drives the eccentric wheel through the motor to drive the screening net 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 seamlessly connected, which improves production efficiency.
