Description

Technical Field

[0001] The embodiments disclosed herein generally relate to the field of grain processing technology, and in particular to grain processing feeding devices and feeding methods. Background Technology

[0002] In modern grain processing and storage, the feeding device serves as a crucial interface for receiving external materials (such as grain trucks and bulk grain piles) and guiding them into the main body of the elevator. Its operational adaptability directly determines the efficiency of the entire processing line. In actual operation, due to the varying models of incoming vehicles (e.g., small agricultural tricycles have low unloading heights, while large dump trucks have high unloading heights and large throwing angles) and the limitations imposed by different material receiving port elevations within the plant, the feeding device must possess the ability to flexibly adjust the feeding height and tilt angle to achieve seamless connection.

[0003] In related technologies, in order to solve the problem of blockage during the feeding process, some feeding devices with internal anti-blockage and uniform feeding functions have emerged. For example, the prior art patent with publication number CN120573442B provides a grain elevator based on modern agricultural machinery. This device has a receiving bin fixedly connected to the elevator frame. The receiving bin is equipped with a screen guided by guide columns and supported by springs. The screen is driven to vibrate back and forth through a pulley, rotating block and linkage mechanism to avoid excessive accumulation of grain and improve the uniformity of feeding to a certain extent.

[0004] Although the existing technical solutions mentioned above achieve the effect of improving the uniformity of feeding by setting up a vibrating screen, the material receiving hopper and the main unit of the elevator are rigidly fixed. This "fixed" structure completely locks the spatial position of the feeding port. When facing grain transport vehicles with different unloading heights, the operators cannot adjust the height of the feeding hopper or the angle of the receiving hopper. They can only be forced to carry out time-consuming and laborious secondary transfer or build a temporary elevated platform, which seriously restricts the feeding efficiency. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a feeding device and feeding method for grain processing, which can effectively solve the problem that it is inconvenient to adjust the feeding height or receiving angle in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: One aspect of the present invention provides a feeding device for grain processing, comprising: A support base is used to support and fix various components and mechanisms. A rotary frame is rotatably provided at the top of the support base. Two inner support plates are arranged opposite each other inside the rotary frame.

Two drive rollers are provided, which are rotatably mounted at the bottom of the rotary frame and located inside the belt conveyor to support and drive the belt conveyor. The first support roller is set on one side of the rotary frame, and a discharge pipe is set on one side of the first support roller. The first support roller can drive the discharge pipe to move relative to the rotary frame to adjust the discharge height of the discharge pipe. The second support roller is located on one side of the rotary frame. Both the first and second support rollers are located inside the belt conveyor and provide support for the belt conveyor.

[0007] In some examples, a support ring is provided on one side of an inner support plate away from the feed tube; The support ring and the feed pipe are both located on the outside of the belt conveyor, providing support for the belt conveyor.

[0008] In some examples, a rotary push rod is rotatably mounted on the top of the support base, and the output end of the rotary push rod is rotatably mounted on the outside of the rotary frame.

[0009] In some examples, a plurality of belt plates are evenly arranged on the outer side of the belt conveyor; A partition is fixedly installed between the two inner support plates, and the partition is located on one side of the feeding section of the belt conveyor.

[0010] In some examples, the discharge pipe is connected to the output end of an adjusting push rod, which can push the discharge pipe to move relative to the rotary frame; The discharge pipe is connected to a first linear transmission component on the side near the second support roller; The second support roller is rotatably disposed on the inner side of the support base. A second linear transmission component is connected to one side of the support base. A linkage component is provided between the first linear transmission component and the second linear transmission component, so that when the first linear transmission component drives the first support roller away from one of the drive rollers, the second linear transmission component drives the second support roller closer to the other drive roller.

[0011] In some examples, a sliding guide rail is fixedly provided on one side of the inner support plate, and the second linear transmission member is slidably disposed on one side of the sliding guide rail.

[0012] In some examples, the support seat is slidably disposed on one side of the second linear transmission member, and a tension adjustment mechanism for adjusting the relative position of the second support roller and the second linear transmission member is provided on the outer side of the support seat. The tension adjustment mechanism includes: A connecting frame, which is connected to one side of the second linear transmission member; An adjusting component is rotatably disposed through the connecting frame. The adjusting component includes a threaded section, and a movable ring is threaded on the outer side of the threaded section. The movable ring is connected to one side of the support base.

[0013] In some examples, a receiving bin is provided on one side of the supporting base, and a grain guide pipe is provided at the bottom of the receiving bin, the grain guide pipe being rotatably disposed on one side of the feed pipe; A spiral conveying rod is installed inside the grain guide pipe, and the spiral conveying rod extends to the feed pipe.

[0014] In some examples, a grid plate is provided on the inner side of the top of the receiving bin, and a lever is provided in the gap of the grid plate; The spiral conveyor is driven on one side of the drive roller, and a turntable is connected to the side of the spiral conveyor away from the drive roller.

[0016] The technical solution provided by this invention has the following advantages compared with the prior art: This invention enables flexible adjustment of the conveying angle of the belt conveyor within the rotating frame by setting a rotatable rotating frame at the top of the supporting base; the discharge pipe can be moved relative to the rotating frame by the first support roller, and the discharge height can be adjusted independently to match the height requirements of different receiving devices and achieve precise docking and feeding.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] The present invention will be further described below with reference to embodiments.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the grain processing feeding device disclosed in this embodiment is mainly used for conveying and feeding grains, and is adapted to subsequent grain processing steps. Its core structure includes a bearing base 1, a rotary frame 11, an inner support plate 12, a belt conveyor 2, a drive roller 3, a first support roller 4, a second support roller 5, a feed pipe 122, a discharge pipe 41, and related supporting structures. All components work together to achieve stable grain conveying and meet feeding requirements.

[0023] Among them, the bearing base 1 is the installation foundation of the entire feeding device, which is used to uniformly support and fix the various components of the device to ensure the stability of the overall structure of the device. Its specific structure can be made of rigid plate splicing or integral molding, as long as it can realize the installation and fixing of various components and the overall support function, there is no need to limit the specific size and material. In actual operation, the bearing base 1 can be fixed to the ground by means of anchor bolts, or lockable wheels can be installed at the bottom to facilitate movement to different positions for feeding.

[0024] The rotary frame 11 is rotatably mounted on the top of the support base 1, and can rotate around the support base 1 at a certain angle, thereby driving the entire device to adjust the conveying angle to adapt to different processing station requirements. Additionally, a top shell 111 is fixedly mounted on the top of the rotary frame 11. Two inner support plates 12 are arranged opposite each other on the inner sides of the rotary frame 11 and the top shell 111. The two inner support plates 12 are arranged in parallel and spaced apart, providing a mounting support foundation for the belt conveyor 2, and forming a channel for grain conveying between the two inner support plates 12. The bottom of the inner support plate 12 is provided with a feed pipe 122. One end of the feed pipe 122 is connected to the external feeding structure, and the other end extends into the channel between the two inner support plates 12 for introducing external grains into the device. Specifically, a support pipe is provided on the outer side of the rotary frame 11 corresponding to the feed pipe 122, and the feed pipe 122 is rotatably arranged inside the support pipe. The belt conveyor 2 is arranged inside the rotary frame 11 and forms a stable conveying structure under the limiting effect of the inner support plate 12 and the rotary frame 11, which can realize the continuous conveying of grains.

[0025] Two drive rollers 3 are provided, both rotatably mounted on the bottom area of ​​the rotary frame 11, and the two drive rollers 3 operate synchronously to drive the belt conveyor 2 to rotate, thereby realizing the conveying of grain. The drive rollers 3 are made of rigid structure, which can effectively avoid deformation during operation, ensure the operational stability of the belt conveyor 2, and provide stable support for the belt conveyor 2. The first support roller 4 and the second support roller 5 are respectively set on different sides of the belt conveyor 2, both located on one side of the rotary frame 11, and the positions of the first support roller 4 and the second support roller 5 can be adjusted to adapt to different conveying requirements. The first support roller 4 is rotatably set on one side of the discharge pipe 41 through the bearing plate 411. The discharge pipe 41 is used to guide the grain conveyed by the belt conveyor 2 to the subsequent processing steps, realizing the connection between feeding and processing.

[0026] The drive roller 3 is driven by a drive motor 32. Specifically, a first gear 31 is fixedly provided on both sides of the drive roller 3. One of the first gears 31 is driven to rotate by the drive motor 32. A second gear 33 is meshed between the two first gears 31 on the same side. The second gear 33 is rotatably provided inside the rotary frame 11.

[0027] In the above scheme, the grain feeding device for grain processing operates as follows: after the grain is introduced into the device, the drive structure is activated, driving the drive roller 3 to rotate. The drive roller 3 drives the belt conveyor 2 to run synchronously. The belt conveyor 2 continues to operate under the drive of the drive roller 3, conveying the grain along the channel between the inner support plates 12. By adjusting the positions of the first support roller 4 and the second support roller 5, different conveying height requirements can be accommodated. At the same time, the rotating frame 11 can be flexibly adjusted to ensure that the grain can be accurately conveyed to the subsequent processing station, completing the feeding operation. Through the coordinated cooperation of various components, the above scheme achieves stable and continuous grain feeding. The structural design is reasonable and can be adapted to different processing scenarios, ensuring a smooth and reliable feeding process and meeting the feeding requirements of grain processing at different feeding heights and angles.

[0028] In some examples, a support ring is provided on the side of the inner support plate 12 away from the feed pipe 122. The support ring can be integrally formed with the inner support plate 12, or it can be fixed to the inner support plate 12 by welding or bolting. The support ring and the feed pipe 122 are both located on the outside of the belt conveyor 2, and together they support the belt conveyor 2. The feed pipe 122 and the support ring are both rotatably arranged inside the second gear 33. The feed pipe 122 is located on the side of the belt conveyor 2 closest to the feed end, and the support ring is located on the side of the belt conveyor 2 furthest from the feed end. The two are symmetrically distributed on both sides of the belt conveyor 2. Together with the first support roller 4, the second support roller 5 and the two drive rollers 3 on the inner side, the belt conveyor 2 is supported by the two drive rollers 3, the first support roller 4, the second support roller 5, the support ring and the feed pipe 122 to form a V-shaped part 201 and two straight parts 202. The belt conveyor 2 forms a feeding section from the position corresponding to the feed pipe 122 to the position of the discharge pipe 41. That is, the grain enters between the two inner support plates 12 from the feed pipe 122 and is then conveyed by the belt conveyor 2 to the discharge pipe 41 for discharge.

[0029] In the above scheme, the rotary frame 11, the top shell 111 and the inner support plate 12 further enhance the support stability of the belt conveyor 2, prevent the belt conveyor 2 from having problems such as side offset and deformation during the grain conveying process, and especially avoid the side collapse of the belt conveyor 2 due to the gravity of the grain, ensuring that the belt conveyor 2 always maintains a flat conveying shape, and ensuring the continuity and stability of grain conveying.

[0030] In some examples, the top of the support base 1 is also provided with a rotary push rod 6 for driving the rotary frame 11 to rotate. Both ends of the rotary push rod 6 are rotatably connected, that is, the fixed end of the rotary push rod 6 is rotatably installed on the top of the support base 1, and the output end is rotatably connected to the outside of the rotary frame 11. A rotatable connection structure with a pin and bearing can be used to reduce the friction during rotation and ensure that the rotary push rod 6 can smoothly drive the rotary frame 11 to rotate around the support base 1 when it extends or retracts, avoiding jamming. The rotary push rod 6 can be a hydraulic push rod or an electric push rod, which can achieve precise control of the extension and retraction action, and thus precisely adjust the rotation angle of the rotary frame 11 to meet the usage requirements of different feeding angles.

[0031] In some examples, such as Figure 3 and Figure 4 As shown, several material plates 21 are evenly arranged on the outer side of the belt conveyor 2. The material plates 21 are evenly distributed along the length of the belt conveyor 2 and are fixedly connected to the belt conveyor 2. The material plates 21 can effectively block and lift the grain during the rotation of the belt conveyor 2. Especially when the belt conveyor 2 is inclined, it can prevent the grain from sliding down the surface of the belt conveyor 2, further improving the stability and efficiency of grain conveying and ensuring that each conveying stroke can stably carry a sufficient amount of grain. The feed pipe 122 extends to the top of the belt conveyor 2, ensuring that the grain output from the feed pipe 122 can fall directly onto the conveying surface of the belt conveyor 2 and is located between two adjacent material plates 21, which facilitates the material plates 21 to lift and convey the grain.

[0032] In some examples, the conveyor belt 21 may be arranged in a structure perpendicular to the belt conveyor 2. In other examples, the conveyor belt 21 may be arranged at an angle to one side of the belt conveyor 2. Specifically, when the conveyor belt 21 moves to the feeding section, the top of the conveyor belt 21 is inclined toward the end where the discharge pipe 41 is located, so as to facilitate the support of the grain.

[0033] In some examples, the outer side of the belt conveyor 2 is provided with a fitting wing 22. The fitting wing 22 is located on both sides of the belt plate 21 and is fitted with the corresponding inner support plate 12. The fitting wing 22 can cover the gap between the belt conveyor 2 and the inner support plate 12 to prevent grain from falling from the side gap during the conveying process, ensuring that all grain can be conveyed to the discharge pipe 41 with the belt conveyor 2, reducing grain waste and ensuring the continuity of the feeding process. On the other hand, the fitting wing 22 and the inner support plate 12 can limit and guide the side of the belt conveyor 2, preventing the belt conveyor 2 from shifting or shaking during the rotating conveying process. Especially when the conveyor is tilted or the conveying volume is large, it can further ensure the running stability of the belt conveyor 2 and avoid conveying failure caused by the shift of the belt conveyor 2.

[0034] In the above technical solutions, during the operation of the belt conveyor 2, gaps are easily generated between its side and the outside of the feed pipe 122 and the support ring. Furthermore, the belt conveyor 2 is prone to lateral deviation when rotating, causing grains to slip through the gaps or causing friction and wear between the belt conveyor 2 and the feed pipe 122 and the support ring, affecting the operational stability and service life of the device. Therefore, in some examples, side strips 23 are provided on both sides of the belt conveyor 2. The side strips 23 fit against the outside of the feed pipe 122 and the support ring. As an extension structure of the side of the belt conveyor 2, the side strips 23 can fill the gaps between the belt conveyor 2 and the feed pipe 122 and the support ring, limit the lateral deviation of the belt conveyor 2, and solve the above-mentioned conveying hazards. It is a necessary supplementary structure to ensure the stable operation of the belt conveyor 2 and avoid grain waste.

[0035] In some examples, again as Figure 3 As shown, a partition 121 is fixedly installed between the two inner support plates 12. The partition 121 is located on one side of the feeding section of the belt conveyor 2. The partition 121 is fixed to at least one inner support plate 12. The connection method can be one of the connection methods that can ensure the firmness of the partition 121 installation, such as integral molding, bolt connection or welding. The setting height of the partition 121 can be adapted to the feeding section of the belt conveyor 2, but it needs to avoid the feeding pipe section to avoid affecting the grain entering the conveying channel between the two partitions 121. The main function of the partition 121 is to limit and block the grain in the feeding section of the belt conveyor 2, and prevent the grain from slipping off the side of the belt conveyor 2 during the conveying process. Especially when the belt conveyor 2 is conveyed at an incline, it can effectively prevent the grain from deflecting and falling due to gravity, and ensure the continuity of grain conveying.

[0036] In some examples, in order to reduce the grain falling off the edge of the feed plate 21, the partition 121 may be arranged parallel to the feeding section of the belt conveyor 2, and the partition 121 may be arranged close to the feed plate 21 of the feeding section of the belt conveyor 2, so that the grain can adhere to one side of the partition 121 during the conveying of the feed pair.

[0037] In some examples, such as Figure 5 As shown, the discharge pipe 41 is connected to the output end of the adjusting push rod 42. The adjusting push rod 42 is fixedly installed on the rotary frame 11, and its output end is fixedly connected to the discharge pipe 41. The adjusting push rod 42 can extend and retract, thereby pushing the discharge pipe 41 to move relative to the rotary frame 11, so as to realize the flexible adjustment of the discharge height of the discharge pipe 41 and adapt to the subsequent processing equipment of different heights.

[0038] As the discharge pipe 41 moves, the first support roller 4 moves accordingly, driving the belt conveyor 2 to move in the discharge direction. In order to compensate for the length of the belt conveyor, the second support roller 5 needs to move synchronously. Therefore, in some examples, the side of the discharge pipe 41 near the second support roller 5 is connected to the first linear transmission component 43. The first linear transmission component 43 is fixedly connected to the discharge pipe 41 and can move synchronously with the discharge pipe 41. The second support roller 5 is rotatably mounted on one side of the support base 51. A second linear transmission component 52 is connected to one side of the support base 51. The second linear transmission component 52 is fixedly connected to the support base 51 and can drive the support base 51, the second support roller 5, and the first linear transmission component 43 to move synchronously. Specifically, a linkage is provided between the first linear transmission component 43 and the second linear transmission component 52. The linkage can drive the first linear component and the second linear component to move synchronously, thereby realizing the synchronous movement of the first support roller 4 and the second support roller 5, so that the belt conveyor 2 can achieve length compensation while adjusting the conveying height.

[0039] In some examples, the first linear transmission member 43 and the second linear transmission member 52 can be rack and pinion structures, with corresponding linkage members being gear structures. In this case, the gears are rotatably mounted on one side of the rotary frame 11, and the linkage members of the gear structure mesh with the first linear transmission member 43 and the second linear transmission member 52 respectively, forming a linkage mechanism. This linkage mechanism allows the first linear transmission member 43 to drive the linkage member to rotate when the adjusting push rod 42 pushes the discharge pipe 41 to move, causing the first linear transmission member 43 to move synchronously. The linkage member then drives the second linear transmission member 52 to move in the opposite direction. Ultimately, when the first linear transmission member 43 drives the first support roller 4 away from one of the drive rollers 3, the second linear transmission member 52 drives the second support roller 5 to move closer to the other drive roller 3, thereby compensating for the length change of the belt conveyor 2, ensuring that the belt conveyor 2 is always in a taut state, avoiding problems such as slackness and deviation, and ensuring the stability of grain conveying.

[0040] In some examples, the first linear transmission member 43 and the second linear transmission member 52 can be rod-shaped structures, and the corresponding linkage member is also a connecting rod. In this case, the middle part of the connecting rod is rotatably set on one side of the rotary frame 11. The connecting rod linkage member and the corresponding rod-shaped first linear transmission member 43 and second linear transmission member 52 form a linkage structure. This linkage structure allows the first linear transmission member 43 to drive the second linear transmission member 52 to move synchronously in the opposite direction when the adjusting push rod 42 pushes the discharge pipe 41 to move, causing the first linear transmission member 43 to move synchronously. This can also compensate for the length change of the belt conveyor 2.

[0041] In some examples, the first linear transmission member 43 and the second linear transmission member 52 can be chain structures, with the corresponding linkage being the chain. The chain, together with the first linear transmission member 43 and the second linear transmission member 52, constitutes a chain transmission structure, which can also achieve synchronous reverse movement of the first linear transmission member 43 and the second linear transmission member 52.

[0042] Of course, the linkage can also be some other reasonable mechanical components. The purpose is to compensate for the length change of the belt conveyor 2 by the reverse movement of the first linear transmission component 43 and the second linear transmission component 52. In actual operation, it can be selected from the existing structure according to actual needs, and no limitation is made here.

[0043] In some examples, the second linear transmission component 52 is slidably disposed on one side of the sliding guide rail 123, which is fixedly disposed on one side of the inner support plate 12. The sliding guide rail 123 provides precise guidance for the movement of the second linear transmission component 52, preventing the second linear transmission component 52 from deviating or jamming during movement. This ensures that the second linear transmission component 52 drives the support base 51 and the second support roller 5 to move smoothly, thereby ensuring the linkage accuracy between the first support roller 4 and the second support roller 5 and ensuring the tension stability of the belt conveyor 2.

[0044] In the above technical solution, the second support roller 5 is rotatably mounted inside the support base 51. The support base 51 provides stable mounting support for the second support roller 5. The second support roller 5 can rotate flexibly within the support base 51 and fit against the inner side of the belt conveyor 2, forming support on the other side of the belt conveyor 2 to ensure the conveying stability of the belt conveyor 2. A tension adjustment mechanism 8 is provided on the outer side of the support base 51 for adjusting the relative position of the second support roller 5 and the second linear transmission component 52. The tension adjustment mechanism 8 is used to fine-tune the position of the second support roller 5, thereby compensating for the tension of the belt conveyor 2 and preventing the belt conveyor 2 from becoming too loose or too tight.

[0045] Specifically, in some examples, such as Figure 5 and Figure 6As shown, the tension adjustment mechanism 8 includes a connecting frame 81, an adjusting member 82, and a moving ring 83. The connecting frame 81 is connected to one side of the second linear transmission member 52 and is fixedly connected to the second linear transmission member 52, providing stable installation support for the adjusting member 82. The adjusting member 82 is rotatably disposed through the connecting frame 81 and can flexibly rotate around its own axis on the connecting frame 81. The adjusting member 82 includes a threaded section, and the outer thread of the threaded section is fitted with the moving ring 83. The threaded section and the inner thread of the moving ring 83 are adapted to each other to form a threaded transmission structure. The moving ring 83 is connected to one side of the support seat 51 and is fixedly connected to the support seat 51. When the adjusting member 82 rotates, the moving ring 83 is driven to move along the axial direction of the adjusting member 82 through the threaded transmission, thereby driving the support seat 51 to slide along the second linear transmission member 52, realizing the adjustment of the relative position between the second support roller 5 and the second linear transmission member 52, and achieving the purpose of fine-tuning the tension of the belt conveyor 2.

[0046] In the above technical solution, the first support roller 4 and the second support roller 5, together with the two drive rollers 3 and the tension adjustment mechanism 8, keep the belt conveyor 2 in a stable conveying form, avoid problems such as collapse, deviation and loosening of the belt conveyor 2 during the conveying of grain, and ensure the stability of the conveying process.

[0047] In some examples, such as Figure 1 and Figure 7 As shown, a receiving bin 7 is also provided on one side of the supporting base 1. The receiving bin 7 is connected to one side of the supporting base 1 via a fixing frame 71. The receiving bin 7 is used to receive and transport grains. Its interior has a hollow structure, which can store a certain amount of grains, realize batch feeding of grains, avoid frequent addition of grains, and improve feeding efficiency. A receiving port can be provided at the top of the receiving bin 7 to facilitate the addition of grains into the bin; Figure 8 and Figure 9 As shown, a grain guide pipe 74 is provided at the bottom of the receiving bin 7. The grain guide pipe 74 is fixedly connected to the bottom of the receiving bin 7, connecting the inside and outside of the receiving bin 7. It is used to guide the grain in the receiving bin 7 to the feed pipe 122. Its material can be wear-resistant steel pipe, which is suitable for the wear conditions during the grain conveying process. The grain guide pipe 74 is rotatably set on one side of the feed pipe 122, which is adapted to the rotation angle adjustment of the rotary frame 11. When the rotary frame 11 drives the feed pipe 122 to rotate and adjust the feeding angle, the grain guide pipe 74 can rotate relative to it, ensuring that the grain can always be smoothly conveyed from the receiving bin 7 to the feed pipe 122 through the grain guide pipe 74, avoiding grain blockage due to angle deviation. In the above technical solution, a spiral conveying rod 9 is provided at the bottom end of the grain guide pipe 74. The spiral conveying rod 9 is rotatably installed on the inner side of the bottom end of the grain guide pipe 74 and can rotate flexibly around its own axis. Specifically, it can be connected to the inner wall of the bottom end of the grain guide pipe 74 through a bearing to reduce the friction during rotation. The spiral conveying rod 9 extends to the feed pipe 122, with one end located inside the grain guide pipe 74 and the other end extending into the inside of the feed pipe 122. When the spiral conveying rod 9 rotates, it can continuously and steadily push the grain in the grain guide pipe 74 into the feed pipe 122, and then onto the belt conveyor 2, realizing the orderly conveying of grain, avoiding blockage of grain in the grain guide pipe 74 or the feed pipe 122, and ensuring the continuity of feeding.

[0048] In some examples, again as Figure 7 As shown, a grid plate 75 is installed on the inner side of the top of the receiving hopper 7. The grid plate 75 can be detachably installed on the top of the receiving hopper 7. The grid plate 75 is used to initially intercept and screen the grain entering the receiving hopper 7, preventing large impurities or clumps of grain from entering the grain guide pipe 74 and avoiding blockage. A baffle plate 10 is installed in the gaps of the grid plate 75. The baffle plate 10 can move within the gaps of the grid plate 75 to agitate the grain on the grid plate 75, breaking up any grain stuck in the gaps or clumps of grain, ensuring that the grain can fall smoothly into the grain guide pipe 74 at the bottom of the receiving hopper 7.

[0049] In the above technical solution, the screw conveyor 9 is driven on one side of the drive roller 3. It can establish a transmission connection with the drive roller 3 through gear meshing, chain transmission, etc. The rotation of the drive roller 3 provides power to the screw conveyor 9. There is no need to set up an additional independent drive mechanism, which simplifies the device structure, reduces energy consumption, and ensures the coordination of the operation of the screw conveyor 9 and the belt conveyor 2.

[0050] For example, in a specific example, such as Figure 10 and Figure 11 As shown, a third gear 91 is fixedly installed at the end of the spiral conveyor rod 9 away from the drive roller 3. A speed-changing gear set 92 is installed on the outside of the third gear 91. A gear ring 93 is installed on one side of the speed-changing gear set 92. The gear ring 93 is rotatably installed inside the support tube of the rotary frame 11. A transmission gear is fixedly installed on the side of the first gear 31 near the receiving bin 7. The transmission gear meshes with the gear ring 93, so that the spiral conveyor rod 9 rotates synchronously when the drive roller 3 rotates.

[0051] A turntable 94 is connected to the side of the spiral conveyor rod 9 away from the drive roller 3. The turntable 94 is fixedly connected to the spiral conveyor rod 9 and can rotate synchronously with the spiral conveyor rod 9. A first connecting rod 96 is rotatably connected to the center side of the turntable 94. That is, one end of the first connecting rod 96 is rotatably installed on the eccentric position of the turntable 94 (offset from the center side of the turntable 94) through the eccentric column 95. The other end of the first connecting rod 96 is rotatably connected to a second connecting rod 97. The rotatable connection method adopts a universal joint to ensure smooth rotation between the first connecting rod 96 and the second connecting rod 97 without jamming.

[0052] The end of the second connecting rod 97 is connected to a rotating frame 98. The second connecting rod 97 is fixedly connected to the rotating frame 98 and can drive the rotating frame 98 to move synchronously. The rotating frame 98 is rotatably set in the receiving bin 7. The rotating frame 98 is rotatably connected to the inner wall of the receiving bin 7 through a rotating shaft and can swing flexibly around the rotating shaft in the receiving bin 7. Multiple paddles 10 are connected to the top of the rotating frame 98. The paddles 10 are fixedly connected to the rotating frame 98 and can move synchronously with the swing of the rotating frame 98. The paddles 10 are embedded in the gaps of the grid plate 75. When the rotating frame 98 swings, it drives the paddles 10 to move back and forth in the gaps of the grid plate 75, thereby agitating and dispersing the grains on the grid plate 75 and further preventing grain blockage.

[0053] In the above technical solution, a first opening 72 is provided on the inner side of the receiving bin 7 corresponding to the second connecting rod 97, and a first arc-shaped plate 73 is fixedly provided on the inner side of the receiving bin 7. A second opening 731 is provided on the inner side of the first arc-shaped plate 73 corresponding to the second connecting rod 97, and a second arc-shaped plate 971 is fixedly provided on the outer side of the second connecting rod 97 corresponding to the first arc-shaped plate 73. The second connecting rod 97 needs to perform reciprocating swinging motion within the corresponding space. The second opening 731 provides swinging space for the second connecting rod 97, allowing the second connecting rod to swing through the first arc-shaped plate 73, thus avoiding the fixed first arc-shaped plate 73 from obstructing or restricting the movement of the second connecting rod 97. The arc-shaped cooperation between the first arc plate 73 and the second arc plate 971 can limit and guide the reciprocating swing trajectory of the second connecting rod 97, constrain the swing amplitude and movement path of the second connecting rod 97, and prevent the second connecting rod 97 from deviating, swaying, or shaking during the movement, so that the reciprocating action of the lever 10 is stable and reliable. Moreover, the two arc plates fit together to form an arc-shaped protective sealing structure, which can effectively block the opening gap at the moving part of the second connecting rod 97, prevent grain particles, grain debris, and dust in the receiving bin 7 from entering the connecting rod transmission part, avoid material jamming of the connecting rod, blockage of the hinge gap, causing the mechanism to jam and the movement to be obstructed, and ensure the smooth operation of the material feeding mechanism for a long time.

[0054] Specific embodiments of this application also describe the feeding method of the aforementioned grain processing feeding device, mainly including: Adjust the angle of the rotary frame 11 relative to the support base 1 to adjust the conveying angle of the grain by the belt conveyor 2 inside the rotary frame 11; according to the feeding angle requirements of the subsequent processing equipment, manually or through the drive mechanism drive the rotary frame 11 to rotate around the top of the support base 1. When the rotary frame 11 rotates, it drives the belt conveyor 2, the first support roller 4, the second support roller 5 and other components inside it to rotate synchronously until the belt conveyor 2 is adjusted to a suitable conveying angle to ensure that the grain can be smoothly conveyed along the belt conveyor 2 to the discharge pipe 41 to meet the subsequent processing requirements.

[0055] Adjust the relative position of the first support roller 4 and the rotary frame 11 so that the first support roller 4 drives the discharge pipe 41 to adjust the discharge height. According to the feeding height requirements of the subsequent processing equipment, the first support roller 4 moves up and down relative to the rotary frame 11 by manual adjustment or drive mechanism. Since the discharge pipe 41 and the first support roller 4 are linked, the first support roller 4 moves synchronously and drives the discharge pipe 41 to move until the discharge pipe 41 is adjusted to the discharge height that matches the feeding port of the subsequent processing equipment, so as to avoid the grain from spilling when it is discharged and ensure the smooth feeding. Grains enter the belt conveyor 2 between the two inner support plates 12 through the feed pipe 122, and are then conveyed by the belt conveyor 2 to the discharge pipe 41 for discharge. Grains to be processed are introduced into the feed pipe 122, and the grains enter the space between the two inner support plates 12 through the channel of the feed pipe 122, precisely landing on the conveying surface of the belt conveyor 2. The drive mechanism is activated to drive the drive roller 3 to rotate, and the drive roller 3 drives the belt conveyor 2 to rotate synchronously. Under the joint support of the first support roller 4, the second support roller 5 and the drive roller 3, the belt conveyor 2 smoothly conveys the grains along its own extension direction until the grains are conveyed to the discharge pipe 41, from which they are output to the subsequent processing equipment, completing one feeding process.

[0056] It is worth noting that the grain processing feeding device described in this application has the following advantages over the prior art: The tilt angle of the belt conveyor 2 is adjusted by rotating the rotary push rod 6 to drive the rotary frame 11 to rotate, thereby adjusting the conveying tilt angle. The receiving bin 7 is fixed on the bearing base 1 and does not rotate with the rotary frame 11, so that the receiving port position always remains stable.

[0057] By adjusting the push rod 42 to drive the first support roller 4 to move, the height of the first support roller 4 can be adjusted, thereby adjusting the height of the discharge pipe 41.

[0058] When adjusting the feeding height, the first linear transmission component 43, the linkage component and the second linear transmission component 52 work together to achieve synchronous movement compensation of the first support roller 4 and the second support roller 5, thus ensuring the stability of the V-shaped part 201 of the belt conveyor 2. By rotating the adjusting component 82 to drive the moving ring 83 to slide the support base 51, the relative position of the second support roller 5 and the second linear transmission component 52 can be finely adjusted, which can conveniently and quickly compensate for the tension of the belt conveyor 2.

[0059] In practical applications, the feeding method for receiving hopper 7 is as follows: After the grain is poured into the receiving hopper 7, it is initially intercepted by the grid plate 75; During this process, the power of the drive motor 32 is transmitted to the gear ring 93 via the transmission gear, and then to the third gear 91 via the speed change gear set 92, which drives the spiral conveyor rod 9 to rotate. The spiral conveyor rod 9 pushes the grain above the grid plate 75 into the grain guide pipe 74. At the same time, the turntable 94 at the end of the screw conveyor rod 9 rotates synchronously, and the eccentric column 95 on the turntable 94 makes a circular motion, pulling the first connecting rod 96. The first connecting rod 96 pulls the second connecting rod 97 through the universal joint. The second connecting rod 97 drives the rotating frame 98 to swing back and forth inside the receiving bin 7. The paddle plate 10 fixed on the rotating frame 98 moves back and forth inside the grid plate 75, thus dispersing the grain stuck on the grid plate 75.
