Description

Technical Field

[0001] This invention relates to agricultural machinery and devices, specifically to a high-efficiency, non-destructive impurity removal and conveying device for fresh corn. Background Technology

[0002] In existing fresh corn harvesters, after the ears are picked by the ear-picking device, they enter the ear bin in roughly three steps: first, they are collected and transported by a bidirectional spiral gathering device; second, they are removed by a fan system; and third, they fall into the ear bin by a conveying device.

[0003] Regarding the existing bidirectional spiral auger device for the first step, it can collect ears and convey them to a certain extent. However, due to its rigid structure, the ears are easily damaged by mechanical means and are also prone to squeezing damage, which affects the quality of fresh corn and subsequent processing. In addition, the working space of the auger device is small, which can easily cause the corn ears to accumulate and block, affecting work efficiency.

[0004] Regarding the second step, the existing typical fan cleaning device is still sufficient. However, relying solely on the fan for impurity removal will still result in a high impurity content after the impurity removal device has been used.

[0005] Regarding the typical existing conveying devices in the third step, in corn harvesters, the ear conveying device is generally a scraper conveyor or a screw conveyor. Although scraper conveyors are reliable, their structure is relatively complex; while screw conveyors, although simple in structure, are larger in size and are more likely to damage the ears.

[0006] In summary, existing technologies have problems such as easily damaging corn ears, high impurity content, and large device size. Summary of the Invention

[0007] The purpose of this invention is to overcome the above-mentioned problems and provide a high-efficiency, non-destructive impurity removal and conveying device for fresh corn. This conveying device has the advantages of less damage to corn ears, low impurity content, and small size.

[0008] The objective of this invention is achieved through the following technical solution: A high-efficiency, non-destructive impurity removal and conveying device for fresh corn includes an integrated conveying and impurity removal mechanism and an air separation and impurity removal mechanism; The integrated conveying and impurity removal mechanism includes an integrated conveying and impurity removal frame, integrated conveying and impurity removal rollers, a rotary drive mechanism for driving the integrated conveying and impurity removal rollers to rotate, an oscillation drive mechanism for driving the integrated conveying and impurity removal rollers to oscillate, and a weight sensor for detecting the weight of the integrated conveying and impurity removal rollers. Multiple integrated conveying and impurity removal rollers and weight sensors are provided, and the multiple integrated conveying and impurity removal rollers are distributed in a rectangular array. The top surface of the integrated conveying and impurity removal frame has multiple sets of roller mounting holes, and a portion of the wheel surface of each integrated conveying and impurity removal roller protrudes upward through the corresponding roller mounting hole and onto the top surface of the integrated conveying and impurity removal frame. Along the direction in which the corn enters, a discharge tray is provided on one or both sides of the integrated conveying and impurity removal frame. The oscillation center of the integrated conveying and impurity removal rollers extends vertically. The air separation and impurity removal mechanism includes an air separation and impurity removal hood and an impurity removal fan installed inside the air separation and impurity removal hood. The inlet of the air separation and impurity removal hood is located above multiple sets of integrated conveying and impurity removal rollers.

[0009] In a preferred embodiment of the present invention, the swing drive mechanism is provided in multiple groups, and each group of swing drive mechanisms includes a swing mounting frame, a swing limiting plate, a swing drive motor and a swing transmission assembly. The swing mounting bracket and swing limiting plate are both fixedly installed below the top surface of the integrated conveying and impurity removal frame. The swing drive motor is directly or indirectly mounted on the swing mounting bracket, and its output shaft is connected to the integrated conveying and impurity removal rollers via the swing transmission assembly. With this structure, driven by the swing drive motor, the swing transmission assembly causes the integrated conveying and impurity removal rollers to swing, thereby changing their orientation to convey the corn ears to the side discharge tray.

[0010] Furthermore, the swing transmission assembly includes a first swing connecting rod, a swing connecting rod, and a second swing connecting rod. One end of the first swing connecting rod is connected to the output shaft of the swing drive motor via a quick reset assembly. The other end of the first swing connecting rod is rotatably connected to one end of the swing connecting rod. One end of the second swing connecting rod is rotatably connected to the swing limiting plate and passes through the swing limiting plate upwards to be rotatably connected to the integrated conveying and impurity removal roller. The other end of the first swing connecting rod is rotatably connected to the other end of the swing connecting rod. The distance between the center of the connection point of the first swing connecting rod on the quick reset assembly and the center of the connection point of the first swing connecting rod on the swing connecting rod is equal to the distance between the center of the connection point of the second swing connecting rod on the swing limiting plate and the center of the connection point of the second swing connecting rod on the swing connecting rod. With the above structure, driven by the swing drive motor, the quick reset component transmits power to the first swing connecting rod. The first swing connecting rod carries the swing connecting rod to perform a translational movement with the attitude unchanged, thereby driving the second swing connecting rod to swing around the rotation center on the swing limit plate. The conveying and impurity removal integrated roller swings synchronously, completing the attitude change.

[0011] Furthermore, each set of swing drive mechanisms has four second swing connecting rods, which are distributed in a rectangular array and divided into two groups. Each group of second swing connecting rods includes two parallel second swing connecting rods. This structure allows for the arrangement of multiple sets of second swing connecting rods and integrated conveying and impurity removal rollers, achieving a one-to-many power transmission mode. This reduces the number of drive motors used, simplifies the wiring of the electrical control system, and lowers the overall manufacturing cost and power consumption of the device. Simultaneously, it ensures complete synchronization of the movements of multiple integrated conveying and impurity removal rollers within the same group, facilitating unified and coordinated sorting of materials within the coverage area.

[0012] Furthermore, the weight sensor is positioned between the first swing link and the swing linkage. This allows for a rapid and accurate reflection of the real-time weight status of the material above, providing a high-response and high-precision input signal for subsequent weight judgment and sorting control.

[0013] Furthermore, the quick reset assembly includes a mounting box, a first quick reset pendulum, a second quick reset pendulum, a composite swing transmission component, and a quick reset mounting base. The mounting box is fixedly mounted on the swing mounting frame, and the swing drive motor is located inside the mounting box. One end of the first quick reset pendulum is fixedly connected to the output shaft of the swing drive motor, and the other end of the first quick reset pendulum is provided with a first hole internal transmission part. One end of the second quick reset pendulum is rotatably connected to the quick reset mounting base, and the second quick reset pendulum is provided with a quick reset elongated hole. The composite swing transmission component includes a composite swing rotating part, an intermediate swing connecting part, and a second hole internal transmission part. The composite swing rotating part is rotatably connected to the mounting box and passes upward through the mounting box to be fixedly connected to one end of the first swing connecting rod. The intermediate swing connecting part connects between the composite swing rotating part and the second hole internal transmission part. Both the first hole internal transmission part and the second hole internal transmission part extend into the quick reset elongated hole of the second quick reset pendulum.

[0014] With the above structure, when the gravity sensor does not detect any fresh corn ears, the swing drive mechanism remains stationary. When the gravity sensor detects an ear, the swing drive motor starts, driving the first quick-reset swing member to swing in the corresponding direction. At the same time, the transmission part inside the first hole of the first quick-reset swing member transmits power to the second quick-reset swing member. The second quick-reset swing member swings around the rotation center of the quick-reset mounting base. Since the transmission part inside the second hole of the composite swing transmission component also cooperates in the quick-reset elongated hole of the second quick-reset swing member, the second quick-reset swing member transmits power to the transmission part inside the second hole of the composite swing transmission component. Then, through the intermediate swing connecting part, the composite swing rotating part is driven to rotate, thereby transmitting the power of the swing drive motor to the first swing connecting rod. Finally, through the upper transmission structure, the power is transmitted to the integrated conveying and impurity removal roller, causing the integrated conveying and impurity removal roller to swing and convey the corn ears to the side unloading tray. Furthermore, during the aforementioned oscillation process, from the original position of the integrated conveying and impurity-removing roller to its maximum oscillation position, assuming a 90° angle, the first quick-reset swing member swings at an angle greater than 180° with the oscillation drive motor. Therefore, during reset, the oscillation drive motor drives the first quick-reset swing member to oscillate at the same speed, causing the integrated conveying and impurity-removing roller to swing back from its maximum position to its original position. This swing angle is also assumed to be 90°, but the first quick-reset swing member's swing angle is less than 180°. In other words, the time taken for the first quick-reset swing member to swing back to its original position is shorter. In other words, the reset oscillation speed of the integrated conveying and impurity-removing roller will be faster, thus achieving rapid reset and improving conveying efficiency! Furthermore, the rotary drive mechanism includes a rotary drive motor and a rotary transmission assembly. The rotary drive motor is fixedly mounted on the integrated conveying and impurity removal frame. The rotary transmission assembly includes a belt drive assembly, a rotary drive shaft, and O-belts. Multiple belt drive assemblies are provided and connected between the rotary drive motor and the rotary drive shaft, or between two rotary drive shafts. Multiple rotary drive shafts are provided and evenly arranged below the integrated conveying and impurity removal rollers along a direction parallel to the corn's entry direction. Multiple annular mounting grooves are provided on the rotary drive shafts, evenly distributed along their axis. Annular mounting grooves are provided on the integrated conveying and impurity removal rollers. Multiple O-belts are provided, and each O-belt fits into the corresponding annular mounting groove on the rotary drive shaft and the annular mounting groove on the integrated conveying and impurity removal roller. With this structure, a single rotary drive motor provides the driving force, and the rotary transmission assembly drives all the integrated conveying and impurity removal rollers to rotate, completing the material conveying process. Furthermore, by setting an O-belt, rotational power can be transmitted not only in the original position but also adapt to the oscillation of the integrated conveying and impurity removal roller, thus transmitting rotational power as well. The structure is simple and effective. In a preferred embodiment of the present invention, the integrated conveying and impurity removal frame is equipped with a gravity aggregation processing module, which collects all weight sensor data to sense the total amount and accumulation degree of materials in the entire working space. The sensed values ​​are used to regulate the rotational speed of the impurity removal fan and the rotational speed (non-oscillation speed) of the integrated conveying and impurity removal roller, thereby achieving dual intelligent autonomous speed regulation of the fan and the integrated conveying and impurity removal roller. At the same time, it further enhances the connectivity and compatibility between the novel combination of the impurity removal fan and the integrated conveying and impurity removal roller.

[0015] In a preferred embodiment of the present invention, one end of the feeding tray is hinged to the integrated conveying and impurity removal frame. An angle adjustment mechanism is provided below the feeding tray, comprising an angle adjustment drive motor and an angle adjustment transmission assembly. A lower mounting seat is provided on the outer wall of the integrated conveying and impurity removal frame, and the angle adjustment drive motor is fixedly mounted on the lower mounting seat. An upper mounting seat is provided on the lower bottom surface of the feeding tray, and the upper mounting seat has an adjustment sliding transmission hole. The angle adjustment transmission assembly includes an angle adjustment rack and an angle adjustment gear. The angle adjustment rack passes vertically through the lower mounting seat, and its upper end engages with the adjustment sliding transmission hole via an angle adjustment crossbar. A vertical guide structure is provided between the angle adjustment rack and the lower mounting seat. The angle adjustment gear is connected to the output shaft of the angle adjustment drive motor. With the above structure, when the angle of the feeding tray needs to be adjusted, the angle adjustment drive motor drives the angle adjustment gear to rotate, which in turn moves the angle adjustment rack vertically, realizing the up-and-down flipping of the feeding tray. This completes the angle adjustment of the feeding tray, optimizes the falling trajectory of the ears, and ensures that the ears fall accurately and gently into the ear bin or collection container, reducing collisions and damage during the falling process and enhancing the adaptability of the device to different machine models or operating environments. Furthermore, one adjustment sliding transmission hole length can achieve twice the displacement of the angle adjustment rack. One reciprocating motion within the slide groove can drive the feeding tray to open and close from 0° to 180°.

[0016] Furthermore, the vertical guide structure includes a vertical guide groove and a vertical guide block. The vertical guide groove is formed on the angle adjustment rack, and the vertical guide block is fixedly mounted on the lower mounting base.

[0017] In a preferred embodiment of the present invention, the impurity removal fan is equipped with a blade located below the blades of the fan. This allows for the immediate shredding of lightweight impurities (such as blades and debris) drawn into the fan. The shredded impurities are smaller and lighter, making them easier for the fan's airflow to remove from the system, preventing long-fiber impurities from entangled in the blades and causing reduced fan efficiency or malfunction. Furthermore, the shredded impurities are easier to collect or return to the field, improving the thoroughness of the impurity removal process and the convenience of subsequent processing.

[0018] Compared with the prior art, the present invention has the following advantages: 1. Multiple independently rotating and swinging rollers are used as the core conveying and sorting components, replacing the traditional rigid auger or scraper. The contact between the rollers and the ears is flexible rolling and pushing, avoiding rigid scraping, squeezing and collision, which significantly reduces mechanical damage to the ears, skin damage and kernel loss, thereby better maintaining the commercial quality and processing value of fresh corn.

[0019] 2. By using a weight sensor to identify the weight difference between the ears of fruit and light impurities (such as straw) in real time, and driving the rollers to swing in a directional manner, the active and precise sorting of the ears of fruit is achieved. At the same time, the negative pressure fan above can efficiently remove light impurities such as blades and dust, and shred the sucked-in impurities. The dual effect greatly reduces the impurity content of the output ears of fruit.

[0020] 3. The functions of conveying, sorting (swinging) and preliminary impurity removal (impurity leakage between rollers) are integrated into an integrated roller mechanism, which works in conjunction with the upper-mounted air separation mechanism. This integrated design avoids the lengthy layout and volume expansion problems caused by multiple independent devices connected in series in traditional technology, making the entire device structure more compact and saving installation space on the harvester.

[0021] 4. The wide working surface formed by multiple rollers arranged in parallel provides a larger flow space for materials, avoiding the problems of ear accumulation and blockage caused by narrow channels in traditional auger devices. The continuous rotary conveying combined with controllable swing sorting ensures the continuity and smoothness of material processing, thereby improving the work efficiency and reliability of the entire harvesting process.

[0033] To enable those skilled in the art to fully understand the technical solutions of the present invention, the present invention will be further described below in conjunction with embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0034] Example 1 Combination Figures 1-3 The efficient and non-destructive impurity removal and conveying device for fresh corn in this embodiment includes an integrated conveying and impurity removal mechanism and an air separation and impurity removal mechanism. The integrated conveying and impurity removal mechanism includes an integrated conveying and impurity removal frame 1, integrated conveying and impurity removal rollers 2, a rotation drive mechanism for driving the integrated conveying and impurity removal rollers 2 to rotate, an oscillation drive mechanism for driving the integrated conveying and impurity removal rollers 2 to oscillate, and a weight sensor 3 for detecting the weight of the integrated conveying and impurity removal rollers 2. Multiple integrated conveying and impurity removal rollers 2 and weight sensors 3 are provided. Multiple integrated conveying and impurity removal rollers 2 are distributed in a rectangular array. Specifically, 2*2 integrated conveying and impurity removal rollers constitute a unit, and the whole device forms a 4*4 layout of 16 units. The material is conveyed at the same time during the entire impurity removal process. Furthermore, along the material line in the diagram, there are four rows of conveying and impurity removal integrated rollers 2 on the left and four rows of conveying and impurity removal integrated rollers 2 on the right. The ears of fruit swing to the left on the four rows of conveying and impurity removal integrated rollers 2, and the same applies to the right side. At the same time, the four rows of conveying and impurity removal integrated rollers 2 swing at different angle gradients, such as 30° to 60°, thereby greatly shortening the movement distance of the ears of fruit and improving the efficiency of the machine.

[0035] Combination Figures 1-3 The top surface of the conveying and cleaning integrated frame 1 is provided with multiple sets of roller mounting holes. Part of the wheel surface of the conveying and cleaning integrated roller 2 protrudes above the top surface of the conveying and cleaning integrated frame 1 by passing through the corresponding roller mounting holes. Along the direction of corn entry, both sides of the conveying and cleaning integrated frame 1 are provided with a discharge tray 4. The swing center of the conveying and cleaning integrated roller 2 extends vertically.

[0036] Combination Figures 4-6The swing drive mechanism comprises multiple sets, each set including a swing mounting frame 5, a swing limiting plate 6, a swing drive motor 7, and a swing transmission assembly. The swing mounting frame 5 and the swing limiting plate 6 are fixedly mounted below the top surface of the integrated conveying and impurity removal frame 1. The swing drive motor 7 is directly or indirectly mounted on the swing mounting frame 5. The output shaft of the swing drive motor 7 is connected to the integrated conveying and impurity removal roller 2 via the swing transmission assembly. The swing transmission assembly includes a first swing connecting rod 8, a swing connecting rod 9, and a second swing connecting rod 10. One end of the first swing connecting rod 8 is connected to the output shaft of the swing drive motor 7 via a quick reset assembly. The other end of the first swing connecting rod 8 is rotatably connected to one end of the swing connecting rod 9. One end of the second swing connecting rod 10 is rotatably connected to the swing limiting plate 6 and passes through the swing limiting plate 6 upwards to be rotatably connected to the conveying and impurity removal integrated roller 2. The other end of the first swing connecting rod 8 is rotatably connected to the other end of the swing connecting rod 9. The distance between the center of the connection point of the first swing connecting rod 8 on the quick reset assembly and the center of the connection point of the first swing connecting rod 8 on the swing connecting rod 9 is equal to the distance between the center of the connection point of the second swing connecting rod 10 on the swing limiting plate 6 and the center of the connection point of the second swing connecting rod 10 on the swing connecting rod 9. With the above structure, under the drive of the swing drive motor 7, the quick reset assembly transmits power to the first swing connecting rod 8, which carries the swing connecting rod 9 to perform a translational movement with a constant attitude, thereby driving the second swing connecting rod 10 to swing around the rotation center on the swing limiting plate 6. The conveying and impurity removal integrated roller 2 swings synchronously, completing the attitude change.

[0037] Combination Figures 4-5 Each set of swing drive mechanisms has four second swing connecting rods 10, which are arranged in a rectangular array and divided into two groups. Each group of second swing connecting rods 10 includes two parallel second swing connecting rods 10. With the above structure, multiple sets of second swing connecting rods 10 and integrated conveying and impurity removal rollers 2 can be arranged to realize a one-to-many power transmission mode, reduce the number of drive motors used, simplify the wiring of the electrical control system, reduce the overall manufacturing cost and power consumption of the device, and at the same time ensure the complete synchronization of the operation of multiple integrated conveying and impurity removal rollers 2 in the same group, which is conducive to the unified and coordinated sorting of materials in the coverage area.

[0038] Combination Figures 4-5 The weight sensor 3 is positioned between the first swing link 8 and the swing link 9. This allows for a rapid and accurate reflection of the real-time weight status of the material above, providing a high-response and high-precision input signal for subsequent weight judgment and sorting control.

[0039] Combination Figures 6-9The quick reset assembly includes a mounting box 11, a first quick reset swing member 12, a second quick reset swing member 13, a composite swing transmission member 14, and a quick reset mounting base 15. The mounting box 11 is fixedly mounted on the swing mounting frame 5, and the swing drive motor 7 is disposed inside the mounting box 11. One end of the first quick reset swing member 12 is fixedly connected to the output shaft of the swing drive motor 7, and the other end of the first quick reset swing member 12 is provided with a first hole internal transmission part 12-1. One end of the second quick reset swing member 13 is rotatably connected to the quick reset mounting base 15, and the second quick reset swing member 13 is provided with... The composite swing transmission component 14 includes a composite swing rotating part 14-1, an intermediate swing connecting part 14-2, and a second hole in-transmission part 14-3. The composite swing rotating part 14-1 is rotatably connected to the mounting box 11 and passes upward through the mounting box 11 to be fixedly connected to one end of the first swing connecting rod 8. The intermediate swing connecting part 14-2 is connected between the composite swing rotating part 14-1 and the second hole in-transmission part 14-3. The first hole in-transmission part 12-1 and the second hole in-transmission part 14-3 both extend into the quick-reset elongated hole 13-1 of the second quick-reset swing component 13.

[0040] With the above structure, when the gravity sensor does not detect any fresh corn ears, the swing drive mechanism remains stationary during operation. When the gravity sensor detects the corn ears, the swing drive motor 7 starts, driving the first quick-reset swing member 12 to swing in the corresponding direction. At the same time, the transmission part 12-1 in the first hole of the first quick-reset swing member 12 transmits power to the second quick-reset swing member 13. The second quick-reset swing member 13 swings around the rotation center of the quick-reset mounting base 15. Since the transmission part 14-3 in the second hole of the composite swing transmission member 14 also cooperates in the quick-reset elongated hole 13-1 of the second quick-reset swing member 13, the second quick-reset swing member 13 transmits power to the transmission part 14-3 in the second hole of the composite swing transmission member 14. Then, through the intermediate swing connecting part 14-2, the composite swing rotating part 14-1 is driven to rotate, thereby transmitting the power of the swing drive motor 7 to the first swing connecting rod 8. Finally, through the upper transmission structure, the power is transmitted to the conveying and impurity removal integrated roller 2, causing the conveying and impurity removal integrated roller 2 to swing and convey the corn ears to the side discharge tray 4. Furthermore, during the aforementioned oscillation process, from the original position of the conveying and impurity removal integrated roller 2 (e.g., Figure 8 When the pendulum swings to its maximum position (assuming 90°), the first quick-reset pendulum 12 swings with the pendulum drive motor 7 at an angle greater than 180° (e.g., ...). Figure 9(See angle a in the figure). During reset, the swing drive motor 7 drives the first quick reset pendulum 12 to swing at the same speed. The conveying and impurity removal integrated roller 2 swings back from its maximum position to its original position. The swing angle of the conveying and impurity removal integrated roller 2 is also 90°. However, the swing angle of the first quick reset pendulum 12 is less than 180° (angle b in the figure). That is, the time taken for the first quick reset pendulum 12 to swing back to its original position is less. In other words, the reset swing speed of the conveying and impurity removal integrated roller 2 will be faster, thereby achieving quick reset and improving conveying efficiency! Combination Figures 1-3 The rotary drive mechanism includes a rotary drive motor 16 and a rotary transmission assembly. The rotary drive motor 16 is fixedly mounted on the integrated conveying and impurity removal frame 1. The rotary transmission assembly includes a belt drive assembly, a rotary drive shaft 17, and O-belts 18. Multiple belt drive assemblies are provided and connected between the rotary drive motor 16 and the rotary drive shaft 17, or between two rotary drive shafts 17. Multiple rotary drive shafts 17 are evenly arranged below the integrated conveying and impurity removal rollers 2, parallel to the direction in which the corn enters. Multiple annular mounting grooves are evenly distributed along the axis of the rotary drive shaft 17. Annular mounting grooves are provided on the wheels of the integrated conveying and impurity removal rollers 2. Multiple O-belts 18 are provided and fit into the corresponding annular mounting grooves on the rotary drive shafts 17 and the wheels of the integrated conveying and impurity removal rollers 2. With this structure, a single rotary drive motor 16 provides the driving force, and the rotary transmission assembly drives all the integrated conveying and impurity removal rollers 2 to rotate, completing the material conveying process. Furthermore, by setting the O-belt 18, it is possible not only to transmit rotational power in the original position, but also to adapt to the oscillation of the conveying and impurity removal integrated roller 2, thus transmitting rotational power in the same way. The structure is simple and effective.

[0041] Specifically, the integrated conveying and impurity removal frame 1 is equipped with a gravity aggregation processing module (refer to existing technology) to collect all weight sensing data, realize the sensing of the total amount and accumulation degree of materials in the entire workspace, and adjust the rotation speed of the impurity removal fan 27 and the rotation speed (non-oscillating speed) of the integrated conveying and impurity removal roller 2 through the sensed values, thereby achieving dual intelligent autonomous speed adjustment of the fan and the integrated conveying and impurity removal roller 2, and further enhancing the connectivity and combinability between the new combination of the impurity removal fan 27 and the integrated conveying and impurity removal roller 2.

[0042] Combination Figures 10-11One end of the feeding tray 4 is hinged to the integrated conveying and impurity removal frame 1. An angle adjustment mechanism is provided below the feeding tray 4. The angle adjustment mechanism includes an angle adjustment drive motor and an angle adjustment transmission assembly. The outer wall of the integrated conveying and impurity removal frame 1 is provided with a lower mounting seat 20. The angle adjustment drive motor is fixedly mounted on an upper mounting seat 21 on the lower mounting seat 20. The bottom surface of the feeding tray 4 is provided with an upper mounting seat 21. The upper mounting seat 21 is provided with an adjustment sliding transmission hole 21-1. The angle adjustment transmission assembly includes an angle adjustment rack 22 and an angle adjustment gear 23. The angle adjustment rack 22 passes vertically through the lower mounting seat 20. The upper end of the angle adjustment rack 22 is engaged in the adjustment sliding transmission hole 21-1 through an angle adjustment crossbar 24. A vertical guide structure is provided between the angle adjustment rack 22 and the lower mounting seat 20. The angle adjustment gear 23 is connected to the output shaft of the angle adjustment drive motor. With the above structure, when the angle of the feeding tray 4 needs to be adjusted, the angle adjustment drive motor drives the angle adjustment gear 23 to rotate, which in turn moves the angle adjustment rack 22 vertically, realizing the up-and-down flipping of the feeding tray 4. This completes the angle adjustment of the feeding tray 4, optimizes the falling trajectory of the ears, and ensures that the ears fall accurately and gently into the ear bin or collection container, reducing collisions and damage during the falling process and enhancing the adaptability of the device to different machine models or operating environments. Furthermore, one adjustment of the sliding transmission hole 21-1 can achieve twice the displacement of the angle adjustment rack 22. One reciprocating motion within the slide groove can drive the feeding tray 4 to open and close from 0° to 180°.

[0043] Furthermore, the vertical guide structure includes a vertical guide groove 25 and a vertical guide block 26. The vertical guide groove 25 is formed on the angle adjustment rack 22, and the vertical guide block 26 is fixedly mounted on the lower mounting base 20.

[0044] Combination Figure 1 and Figure 12 The air separation and impurity removal mechanism includes an air separation and impurity removal hood 26 and an impurity removal fan 27 disposed inside the air separation and impurity removal hood 26. The inlet of the air separation and impurity removal hood 26 is located above multiple sets of integrated conveying and impurity removal rollers 2.

[0045] The impurity removal fan 27 is equipped with blades 28 located below the blades of the fan. This allows for the immediate shredding of lightweight impurities (such as blades and debris) drawn into the fan. The shredded impurities are smaller and lighter, making them easier for the fan's airflow to remove from the system, preventing long fiber impurities from entangled in the blades and causing reduced fan efficiency or malfunction. Furthermore, the shredded impurities are easier to collect or return to the field, improving the thoroughness of the impurity removal process and the convenience of subsequent processing.

[0046] Example 2 Combination Figure 1 , Figure 3 and Figure 12 The working principle of the high-efficiency, non-destructive impurity removal and conveying device for fresh corn in this embodiment is as follows: During operation, fresh corn ears are removed by the ear-picking device and enter the device along with stalks, leaves, and other impurities. The material first falls onto the integrated conveying and impurity-removing roller 2, which rotates continuously under the drive mechanism, conveying the ears forward. During the conveying process, a weight sensor 3 integrated below the integrated conveying and impurity-removing roller 2 monitors the weight changes of each set of rollers in real time. Since corn ears are significantly heavier than light impurities such as stalks, when the weight sensor 3 detects a significant increase in weight, it determines that the current object is an ear and then drives the corresponding integrated conveying and impurity-removing roller 2 to swing to the left or right through the corresponding swing drive mechanism, guiding the ear to the corresponding discharge tray 4, thus separating the ear from the impurities. The lighter impurities continue to be conveyed forward with the integrated conveying and impurity-removing roller 2 and are finally discharged from the rear outlet.

[0047] At the same time, the negative pressure fan located above the conveying and impurity removal integrated roller 2 continues to operate, forming a negative pressure airflow inside the air separation and impurity removal hood 26, which sucks in light impurities (such as broken leaves, dust, etc.) that are suspended or fall off during the conveying process. The rotating blades 28 installed inside the fan can further cut the sucked-in impurities, making them easier to process or discharge later, thereby achieving secondary removal of light impurities.

[0048] Throughout the process, the flexible conveying and oscillating sorting of the integrated conveying and impurity removal roller 2 avoids the squeezing and collision damage caused by traditional rigid augers or scrapers, significantly reducing the breakage rate of the ears. At the same time, through the dual impurity removal mechanism of gravity sensing and airflow cleaning, the impurity content of the ears is significantly reduced, achieving efficient and non-destructive (not 100% no damage, but a high probability of no damage, which can be described as extremely low loss) operation that integrates conveying, sorting and impurity removal.

[0049] The above are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
