Description

Technical Field

[0001] This invention relates to the field of rice processing technology, and in particular to a rice processing equipment and a digitalized processing workshop. Background Technology

[0002] In automated rice processing production lines, bucket elevators serve as core conveying equipment, undertaking the task of vertically transferring raw rice and semi-finished products, effectively connecting multiple processes such as cleaning, milling, polishing, and grading.

[0003] The elevator scoops rice from the bottom silo using circulating hoppers, enabling continuous feeding and ensuring the stable operation of the processing line. However, rice grains continuously scatter and accumulate at the bottom of the silo, forming a compacted layer that is difficult to remove. As the equipment continues to operate, this accumulated material not only occupies the effective working space of the bottom silo and obstructs the hopper's circulation path, but also significantly increases the load on the drive motor. This can easily lead to equipment stalls, jams, or even shutdowns, severely disrupting the production line's continuous operation capability.

[0004] Meanwhile, the existing equipment's method of directly scooping and compacting accumulated material with hoppers has structural defects: when the hopper is inserted into a high-density stack, it is very prone to physical damage such as breakage and bursting, which greatly increases the broken rice rate and reduces the product grade and market value; the hopper is repeatedly subjected to friction and impact from the material, which causes wear, deformation and even cracking of the hopper opening, shortens its service life and aggravates the leakage problem, forming a vicious cycle of continuous deterioration of the equipment's operating condition; the fluctuation of the scooping load caused by the accumulation of material in the bottom silo also causes increased equipment vibration and noise, accelerates the wear rate of parts, keeps the failure rate high, and significantly increases the operation and maintenance burden of the production line. Summary of the Invention

[0005] This invention provides a rice processing equipment and a digitalized processing workshop, aiming to solve at least one of the above-mentioned technical problems.

[0006] This invention provides the following technical solution: On the one hand, this application provides a rice processing equipment, including a bucket elevator, wherein a tail wheel, a tensioning mechanism, a feeding mechanism, and a feeding hopper are installed in the bottom bin of the bucket elevator; It also includes a swing feeding mechanism that avoids the feeding mechanism. The bottom of the hopper is provided with an arc-shaped bottom plate. The bottom of the swing feeding mechanism is in contact with the arc-shaped bottom plate. The swing feeding mechanism includes a swing rod and an arc-shaped receiving plate. One end of the swing rod is rotatably connected to the side wall of the hopper, and the other end is fixedly connected to the arc-shaped receiving plate. The arc-shaped receiving plate includes a main body. Side plates are provided on both sides of the main body. An end sealing plate is provided at one end of the main body facing the direction of hopper travel, and a feed inlet is provided at the other end. A first feeding plate, a second feeding plate, and a front guide plate are sequentially arranged along the length of the main body. The first feeding plate, the second feeding plate, and the front guide plate extend along the width direction of the main body. The tops of the first feeding plate and the second feeding plate are inclined towards the feed inlet. The two ends of the first feeding plate and the front guide plate are respectively connected to the side guide plates. The side guide plates are spaced apart from the side plates. When the swing feeding mechanism and the hopper rotate in the same direction around the tail wheel, the first feeding plate and the second feeding plate correspond to a hopper and have a height difference with the corresponding hopper, so that the rice can slide down the first feeding plate and the second feeding plate into the corresponding hopper under the action of gravity.

[0007] The front guide plate forms a first receiving area from the inlet, the first feeding plate forms a first feeding area from the end sealing plate, and the side guide plate and the side plate form a first guiding channel. When the inlet is in a high position, the rice in the first receiving area can enter the first feeding area along the first guiding channel.

[0008] The first feeding area is provided with a first guide member, which is located adjacent to the first material guiding channel. The first guide member forms a guiding slope facing the first material guiding channel to gather the material falling into the first feeding area through the first material guiding channel towards the center of the area. The first guide member also forms a guiding slope facing the end sealing plate to guide the material to continuously converge towards the center during the process of material moving to the first feeding plate in the first feeding area, and to prevent the material from flowing back and re-entering the first material guiding channel.

[0009] A second feeding area is formed between the first feeding plate and the second feeding plate, a second receiving area is formed between the second feeding plate and the front guide plate, and a second guiding channel is formed between the second feeding plate and the side guide plate. When the inlet is at a high position, the rice located in the second receiving area can enter the second feeding area along the second guiding channel.

[0010] The second feeding area is equipped with a second guide member, which is located adjacent to the second feeding channel. The second guide member forms a guiding slope towards the second feeding channel to gather the material falling into the second feeding area through the second feeding channel towards the center of the area. The second guide member also forms a guiding slope towards the first feeding plate to guide the material to continuously converge towards the center during the process of material moving from the second feeding area to the second feeding plate, and to prevent the material from flowing back and re-entering the second feeding channel.

[0011] An clearance opening is provided in the middle of the arc-shaped base plate, and a drive gear is installed in the clearance opening. The drive gear is mounted on the feeding shaft, which passes through the bottom chamber and is connected to the output shaft of the rotary driver. A groove is provided along the length direction at the bottom of the main body, and teeth are provided in the groove, which mesh with the drive gear.

[0012] The bucket elevator has an encoder installed on its head wheel spindle, and a sensor is installed in the bottom hopper to detect whether the buckets have reached a preset position.

[0013] The upper end of the swing arm is fixedly connected to the bushing, and the bushing is rotatably connected to the fixing ring on the side wall of the bottom compartment through the bearing seat. The center of the fixing ring coincides with the axis of the tail wheel.

[0014] The main body at the feed inlet has a wedge-shaped structure, with its bottom surface fitting against the arc-shaped base plate and its top surface being inclined.

[0015] On the other hand, this application provides a digitalized processing workshop, including the above-mentioned rice processing equipment, for lifting and conveying rice.

[0016] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention.

[0017] The beneficial effects of this invention are as follows: This application proposes a rice processing device to solve problems such as material accumulation in the bottom silo, material breakage, and equipment wear in existing technologies, achieving flexible and efficient rice conveying. By installing a swing-feeding mechanism in the bottom silo to collect leaking material, and using a swing arm rotating in the same direction as the hoppers, the collected material is lifted. When the corresponding hopper moves to an upward-facing position, the rice collected in the swing-feeding mechanism can slide down the feed plate into the corresponding hopper under its own weight. Compared with the existing direct scooping method, this eliminates the need for the hoppers to directly contact the accumulated material, significantly reducing the rice breakage rate and extending the hopper's service life. During operation, the periodic swing of the swing arm is synchronized with the hopper's rotation, ensuring... To ensure timely and accurate recovery of spilled rice, an independent swing-feeding mechanism is installed in the bottom silo. This mechanism catches all spilled and leaked rice throughout the process, rather than relying on random scooping from the hopper. All spilled rice is collected by the mechanism, preventing it from accumulating in corners of the silo. When the hopper rotates to a precise position with its opening facing upwards, the mechanism lifts the collected material to the corresponding height for precise one-to-one unloading. Each piece of collected spilled rice is immediately fed into the corresponding hopper, preventing any retention or residue. This ensures more thorough recovery of spilled rice and effectively eliminates the problem of material accumulation in the bottom silo.

[0026] To better understand the purpose, function, and specific design of this invention, the invention will be described in further detail below with reference to the accompanying drawings.

[0027] Traditional bucket elevators 100 commonly suffer from material leakage and accumulation in the bottom hopper 2 during rice processing. This leads to material buildup that cannot be cleared in a timely manner, not only occupying working space and hindering the operation of the buckets 12, but also increasing the drive load, easily causing equipment failure, reducing conveying efficiency, and affecting the quality of the finished product. In addition, directly scooping up the accumulated rice with the buckets 12 can easily cause the rice to break and become damaged, reducing the yield and accelerating the wear of the buckets 12, thus increasing maintenance costs.

[0028] To address these issues, this application proposes a rice processing device to solve problems such as material accumulation in the bottom silo 2, material breakage, and equipment wear in existing technologies, achieving flexible and efficient rice conveying. By installing a swing-feeding mechanism 1 in the bottom silo 2, spilled material is collected. A swing arm rotating in the same direction as the hopper 12 lifts the collected material. When the corresponding hopper 12 moves to an upward-facing position, the rice collected in the swing-feeding mechanism 1 slides down the feed plate into the corresponding hopper 12 under its own weight. Compared to the existing method of directly scooping material from the hopper 12, this method eliminates the need for the hopper 12 to directly contact the accumulated material, significantly reducing rice breakage and extending the service life of the hopper 12. During operation, the periodic swing of the swing arm and the rotation of the hopper 12... Synchronization ensures timely and accurate recovery of spilled material. The bottom hopper 2 is equipped with an independent swing feeding mechanism 1, which catches all spilled and leaked rice throughout the process. Instead of relying on the hopper 12 to randomly scoop material, all spilled material is collected by the mechanism first, preventing it from accumulating in dead corners in the bottom hopper 2. When the hopper 12 rotates to the precise working position with the opening facing upward, the mechanism lifts the collected material to the corresponding height for precise one-to-one unloading. Each piece of collected spilled material can be sent to the corresponding hopper 12 in time, without any retention or residue. The recovery of spilled material is more thorough and effectively prevents the accumulation of material in the bottom hopper 2.

[0029] like Figure 2 - Figure 6 As shown, the present invention provides a rice processing equipment, including a bucket elevator 100, wherein a tail wheel 10, a tensioning mechanism, a feeding mechanism, and a feeding hopper 3 are installed in the bottom bin 2 of the bucket elevator 100; It also includes a swing feeding mechanism 1 that is arranged to avoid the feeding mechanism. The bottom of the hopper 2 is provided with an arc-shaped bottom plate. The bottom of the swing feeding mechanism 1 is in contact with the arc-shaped bottom plate. The swing feeding mechanism 1 includes a swing rod 101 and an arc-shaped receiving plate. One end of the swing rod 101 is rotatably connected to the side wall of the hopper 2, and the other end is fixedly connected to the arc-shaped receiving plate. The arc-shaped receiving plate includes a main body 103. Side plates 104 are provided on both sides of the main body 103. An end sealing plate 105 is provided at one end of the main body 103 facing the direction of travel of the hopper 12, and a feed inlet 106 is provided at the other end. A first feeding plate 111, a second feeding plate 114, and a front guide plate 113 are sequentially arranged along the length direction of the main body 103. The first feeding plate... 111. The second feeding plate 114 and the front guide plate 113 extend along the width direction of the main body 103. The tops of the first feeding plate 111 and the second feeding plate 114 are inclined towards the feed inlet 106. The two ends of the first feeding plate 111 and the front guide plate 113 are respectively connected to the side guide plates 112. The side guide plates 112 and the side plate 104 are spaced apart. When the swing feeding mechanism 1 and the hopper 12 rotate in the same direction around the tail wheel 10, the first feeding plate 111 and the second feeding plate 114 correspond to a hopper 12, and there is a height difference between them and the corresponding hopper 12, so that the rice can slide down into the corresponding hopper 12 through the first feeding plate 111 and the second feeding plate 114 under the action of gravity.

[0030] Bucket elevator 100 is a vertical conveying equipment, including a bottom silo 2, a barrel, and a head. The bottom silo 2 is entirely enclosed by steel plates to form the lower casing. Two connection ports are left at the top for connection with the barrel. An observation port 5 is formed between the two connection ports. A transparent acrylic observation window or an easily accessible maintenance door is installed at the observation port 5. A feed hopper 3 is provided on one side of the casing along its length. The bottom of the feed hopper 3 faces the direction of travel of the hopper 12. When the hopper 12 runs to the bottom of the feed hopper 3, the material falls smoothly into the hopper 12 through the guide plate. The tensioning mechanism includes a movable plate 6 slidably connected to a side plate 104 in the width direction of the bottom chamber 2. A feeding bearing seat is installed inside the movable plate 6. A threaded rod 4 is rotatably connected to the top of the movable plate 6 through a bearing chamber. The threaded rod 4 is threadedly connected to the side wall of the bottom chamber 2. Rotating the threaded rod 4 can drive the movable plate 6 to slide vertically along the side plate 104 to adjust the position of the tail pulley 10, thereby adjusting the tension and ensuring that the belt 11 is always in the optimal tension state. The feeding mechanism includes a feeding shaft 7 installed in the feeding bearing housing, a tail wheel 10 installed on the feeding shaft 7, the tail wheel 10 being connected to the head wheel installed on the machine head via a belt 11, multiple hoppers 12 being installed on the belt 11, and the head wheel being linked with the main drive motor to ensure that the hoppers 12 circulate at a constant speed. The bottom of the bottom compartment 2 is also equipped with a cleaning port 13 for maintenance and cleaning.

[0031] The oscillating feeding mechanism 1 and the feeding mechanism are arranged to avoid collisions. Specifically, when the oscillating feeding mechanism 1 oscillates, it always maintains a safe distance from the hopper 12 to avoid collisions. At the same time, the distance between the two is small enough to ensure that when the oscillating feeding mechanism 1 oscillates to the maximum tilt angle, the first feeding plate 111 faces the opening of the corresponding hopper 12, and the second feeding plate 114 faces the opening of the next hopper 12, ensuring that the rice can smoothly slide into the corresponding hopper 12 under the action of gravity without deviation or spillage. In addition, the two sides of the oscillating feeding mechanism 1, including the side plate 104 and the swing rod 101, also have sufficient clearance with the side wall of the bottom hopper 2 to prevent friction interference during operation. The bottom of the hopper 2 is equipped with an arc-shaped bottom plate, which is made of metal sheet bent into a preset arc and fixed. The curvature of the arc-shaped bottom plate matches the running trajectory of the hopper 12, and its radius is larger than the radius of curvature of the running trajectory of the hopper 12, and also larger than the radius of curvature of the swing trajectory of the swing feeding mechanism 1. The bottom of the swing feeding mechanism 1 is processed into an arc shape that matches the arc-shaped bottom plate, so that the two can fit tightly together during movement, thereby effectively scraping the material and preventing the material from accumulating between them. When the swing feeding mechanism 1 swings to the limit position on one side of the hopper 12's travel direction, on the one hand, the receiving area of ​​the swing feeding mechanism 1 can undertake the main function of receiving the leaked material, and the remaining small amount of leaked material is received by the arc-shaped bottom plate. After one feeding is completed, when the swing feeding mechanism 1 swings to the other side, the residual leaked material accumulated on the arc-shaped bottom plate is shoveled into the first receiving area 109 and the second feeding area 108 by the feed inlet 106.

[0032] The oscillating feeding mechanism 1 includes a swing arm 101 and an arc-shaped receiving plate. One end of the swing arm 101 is rotatably connected to the side wall of the bottom hopper 2 via a bearing, and its swing axis coincides with the rotation axis of the tail wheel 10. The other end is fixedly connected to the arc-shaped receiving plate to ensure that the arc-shaped receiving plate always swings along the running trajectory of the hopper 12 during the swing process, so that the feeding plate and guide plate on the inner surface of the arc-shaped receiving plate and the outer contour of the hopper 12 maintain a constant small gap. The arc-shaped receiving plate includes a main body 103, which is an integrally formed arc-shaped plate. Side plates 104 extend vertically upwards from both sides of the main body 103 to form a groove-shaped structure. An end cap 105 is provided at one end of the main body 103 facing the direction of travel of the hopper 12 to block material. An opening 106 is provided at the other end as a feed inlet 106, through which material enters the interior of the arc-shaped receiving plate.

[0033] The main body 103 is provided with a first feeding plate 111, a second feeding plate 114 and a front guide plate 113 along its length. These plates are made of independent sheet metal, are fixed to the upper surface of the main body 103 by welding, and are arranged perpendicular to the length of the main body 103, extending to the two side edges of the main body 103 to form multiple areas for carrying and guiding materials. The tops of the first feeding plate 111 and the second feeding plate 114 are designed to have a certain tilt angle, with the tilted surface facing the feed inlet 106. This tilt can be achieved by tilting the welded plates so that when the swing feeding mechanism 1 moves to the limit position on the feeding side (the side of the hopper 12 traveling direction), the rice can slide down the first feeding plate 111 and the second feeding plate 114 by gravity. The tilt setting can improve the flowability of the material.

[0034] Side guide plates 112 are connected to both ends of the first feeding plate 111 and the front guide plate 113, respectively. There are two side guide plates 112, located at the left and right ends of the first feeding plate 111 and the front guide plate 113, respectively. A certain distance is reserved between the side guide plates 112 and the side plate 104 of the arc-shaped receiving plate to form a narrow channel. The two ends of the side guide plates 112 can be firmly connected to the ends of the first feeding plate 111 and the front guide plate 113 by welding, and their bottoms are fixed to the upper surface of the main body 103 by welding.

[0035] When the oscillating feeding mechanism 1 and the hopper 12 rotate in the same direction around the tail wheel 10, the first feeding plate 111 and the second feeding plate 114 can be aligned with a rising hopper 12 respectively. By adjusting the swing height of the oscillating feeding mechanism 1, it can be ensured that the tops of the first feeding plate 111 and the second feeding plate 114 are higher than the openings of the corresponding hoppers 12, thus creating a height difference. As a result, when the rice is guided onto these feeding plates, it can slide down the inclined feeding plates into the corresponding hoppers 12 below by its own gravity.

[0036] The rice processing equipment of this application achieves effective cleaning and flexible feeding of accumulated material in the bottom silo 2 by introducing a swing feeding mechanism 1. This mechanism can actively guide the rice in the bottom silo 2 to the hopper 12, avoiding the squeezing and friction caused by the traditional hopper 12 directly scooping up the accumulated material, thereby reducing the rice breakage rate and protecting the material quality. At the same time, this design reduces the wear of the hopper 12, extends the service life of the equipment, and ensures the continuity and stability of material conveying, effectively solving the problems of equipment failure and material loss caused by material accumulation in the bottom silo 2.

[0037] Furthermore, the end sealing plate 105 is an inclined plate with its two ends welded to the inner side of the side plate 104 and its bottom welded to the upper surface of the main plate 103. The main plate 103 and one end of the end sealing plate 105 also form a wedge structure, which together with the end sealing plate 105 constitutes a guide slope. When the swing feeding mechanism 1 swings back to the limit position of the feeding side, it can cooperate with the end sealing plate 105 and the wedge structure to form a continuous and smooth guide path, guiding the rice to slide smoothly into the first feeding area 107 along the slope.

[0038] Furthermore, the first feeding plate 111, the second feeding plate 114, and the front guide plate 113 are all V-shaped, with their apex facing the feed inlet 106. When the swing feeding mechanism 1 swings to the feeding side, the V-shaped structure can effectively gather the rice flow, increase the concentration and accuracy of falling into the hopper 12, and significantly reduce spillage and deviation. When the swing feeding mechanism swings away from the feeding side, the V-shaped structure of the second feeding plate 114 and the front guide plate 113 can effectively guide the rice in the first receiving area 109, the second feeding area 108, and the second receiving area 110 to the corresponding receiving channels, ensuring that the remaining material is collected without stagnation.

[0039] In some embodiments, such as Figure 6 As shown, the front guide plate 113 to the feed inlet 106 forms a first receiving area 109 and a second feeding area 108. The first feeding plate 111 to the end sealing plate 105 forms a first feeding area 107. The side guide plate 112 and the side plate 104 form a first guiding channel 115. When the feed inlet 106 is in a high position, the rice located in the first receiving area 109 and the second feeding area 108 can enter the first feeding area 107 along the first guiding channel 115.

[0040] The first receiving area 109 and the second feeding area 108 refer to the areas defined between the front guide plate 113 and the feed inlet 106 on the main body 103 of the arc-shaped receiving plate of the swing feeding mechanism 1. The main function of this area is to serve as a receiving area for rice entering the swing feeding mechanism 1 from the outside. The rice it mainly receives includes rice that falls freely into the receiving area when the swing feeding mechanism 1 swings to the extreme position on the feeding side, as well as rice that remains at the bottom of the bottom hopper 2 when the swing feeding mechanism 1 swings to the other side.

[0041] The first feeding area 107 refers to the area defined between the first feeding plate 111 and the end sealing plate 105 on the main body 103 of the arc-shaped receiving plate of the swing feeding mechanism 1. When the swing feeding mechanism 1 swings to the extreme position away from the feeding side, the rice located in the first receiving area 109 and the second feeding area 108 slides into this area along the surface of the main body 103 under the action of gravity, providing a temporary storage and preparation area for the material before it is conveyed to the hopper 12, and preparing it for subsequent sliding into the hopper 12 through the first feeding plate 111.

[0042] The first material guide channel 115 refers to the narrow space formed between the side guide plate 112 and the side plate 104 in the swing feeding mechanism 1. It is used to precisely guide the material entering the swing feeding mechanism 1 laterally, ensuring that the material can flow smoothly and directionally from the first receiving area 109 and the second feeding area 108 to the first feeding area 107, and preventing the material from scattering laterally.

[0043] When the feed inlet 106 of the swing feeding mechanism 1 is in a relatively high position due to its swing or overall movement, the rice located in the first receiving area 109 and the second feeding area 108 can be naturally guided and transported to the first feeding area 107 by gravity along the first guiding channel 115 formed by the side guide plate 112 and the side plate 104.

[0044] In some embodiments, such as Figure 6 As shown, a first guide member 116 is provided inside the first feeding area 107, and the first guide member 116 is arranged adjacent to the first material guiding channel 115. The first guide member 116 forms a guiding slope towards the first material guiding channel 115, which is used to gather the material falling into the first feeding area 107 through the first material guiding channel 115 towards the center of the area. The first guide member 116 also forms a guiding slope towards the end sealing plate 105, which is used to guide the material to continuously converge towards the center during the process of material in the first feeding area 107 being transferred to the first feeding plate 111, and to prevent the material from flowing back and re-entering the first material guiding channel 115.

[0045] The first guide member 116 is a structural component used to guide the flow direction and distribution of materials. It can take various forms such as plate, prismatic, or protruding. Its specific shape and size can be optimized according to the characteristics of rice particles and the geometry of the first feeding area 107 to ensure the best guiding effect. The first guide member 116 is arranged adjacent to the first feeding channel 115 to ensure that the rice material can be effectively guided by the first guide member 116 immediately after leaving the first feeding channel 115. This makes the first guide member 116 form a guiding slope facing the first feeding channel 115. When the rice material flows from the first feeding channel 115... When the rice falls into the first feeding area 107, the guide slope can effectively push or guide the material towards the center of the first feeding area 107, thereby achieving the initial aggregation of the material. In addition, the first guide member 116 also forms a guide slope facing the end sealing plate 105, with its inclination direction facing the end sealing plate 105. In the first feeding area 107, during the process of the rice material moving towards the first feeding plate 111, when the rice comes into contact with the guide slope, it will continuously converge towards the center along the slope, effectively suppressing the tendency of the rice to flow back towards the first guiding channel 115. At the same time, the convergence towards the center can better feed the material into the hopper 12.

[0046] In some embodiments, such as Figure 6 As shown, a second feeding area 108 is formed from the first feeding plate 111 to the second feeding plate 114, a second receiving area 110 is formed from the second feeding plate 114 to the front guide plate 113, and a second guiding channel is formed from the distance between the second feeding plate 114 and the side guide plate 112. When the inlet 106 is in a high position, the rice in the second receiving area 110 can enter the second feeding area 108 along the second guiding channel.

[0047] The aforementioned second feeding area 108 is a region located between the first feeding plate 111 and the second feeding plate 114, serving as a temporary storage area for materials. When the swing feeding mechanism 1 swings to a high position away from the feeding side, the rice in the second receiving area 110 slides into the second feeding area 108 under the action of gravity along the second guide channel, preparing for subsequent conveying to the hopper 12. This allows the material to be effectively diverted after entering the oscillating feeding mechanism 1. A portion enters the first receiving area 109 and the second feeding area 108, while the other portion enters the second receiving area 110. The second guide channel is formed by the distance from the second feeding plate 114 to the side guide plate 112. This provides a clear and controlled path for the material located in the second receiving area 110, allowing it to smoothly enter the second feeding area 108. When the inlet 106 of the oscillating feeding mechanism 1 is in a higher position, the material (e.g., rice) will flow downwards from the second receiving area 110 along the second guide channel under the influence of gravity, eventually entering the second feeding area 108. Working in conjunction with the first feeding path, this mechanism completes the receiving, diversion, and conveying of material to the hopper 12, improving the efficiency and reliability of the entire feeding process.

[0048] In some embodiments, such as Figure 6 As shown, a second guide member 117 is provided inside the second feeding area 108, and the second guide member 117 is arranged adjacent to the second material guiding channel. The second guide member 117 forms a guiding slope towards the second material guiding channel, which is used to gather the material falling into the second feeding area 108 through the second material guiding channel towards the center of the area. The second guide member 117 also forms a guiding slope towards the first feeding plate 111, which is used to guide the material to continuously converge towards the center during the process of material in the second feeding area 108 being transferred to the second feeding plate 114, and to prevent the material from flowing back and re-entering the second material guiding channel.

[0049] Similar to the first guide component 116, it is used to gather the material falling into the second feeding area 108 through the second guide channel towards the center of the area, while preventing the rice in the second feeding area 108 from flowing back to the second guide channel.

[0050] Specifically, in this embodiment, both the first guide member 116 and the second guide member 117 are triangular protrusions, with their bottoms attached to the upper surface of the main body 103. The long side of the triangular protrusion of the first guide member 116 is attached to the side plate 104, with one of its inclined sides facing the first material guiding channel 115 and the other inclined side facing the first feeding plate 111. The long side of the triangular protrusion of the second guide member 117 is attached to the side material guiding plate 112, with one of its inclined sides facing the second material guiding channel and the other inclined side facing the first feeding plate 111. The first guide member 116 and the second guide member 117 are isosceles triangular protrusions, with the height from their long side to the vertex slightly greater than the width of the corresponding channel. The first guide member 116 and the second guide member 117 can be fixedly connected to the main body 103 by welding.

[0051] In some embodiments, such as Figure 5 , Figure 7As shown, a clearance opening is provided in the middle of the arc-shaped base plate, and a drive gear 9 is installed in the clearance opening. The drive gear 9 is installed on the feeding shaft 8, which passes through the bottom chamber 2 and is connected to the output shaft of the rotary driver. A groove 119 is provided at the bottom of the main body 103 along the length direction, and teeth 118 are provided in the groove 119. The teeth 118 mesh with the drive gear 9.

[0052] Specifically, the clearance opening in the middle of the arc-shaped base plate is a rectangular through hole along the length of the arc-shaped base plate, so that the drive gear 9 can mesh with the teeth 118 at the bottom of the main body 103, ensuring that the drive gear 9 can accurately drive the main body 103 to reciprocate when the feeding shaft 8 rotates. The tooth profile, module, and number of teeth of the drive gear 9 should be precisely matched with those of the tooth 118 to ensure smooth transmission and reliable meshing. The drive gear 9 is mounted on the loading shaft 8, which is the intermediate transmission shaft connecting the rotary drive and the drive gear 9, and is responsible for transmitting the torque of the rotary drive to the drive gear 9.

[0053] In addition, during the swinging process, the clearance opening of the swinging feeding mechanism 1 is always located at the bottom of the main body 103 to prevent rice from entering.

[0054] The feeding shaft 8 can be rotatably connected to the inner wall of the bottom hopper 2 through the bearing housing, ensuring smooth rotation without deviation; the bearing housing is embedded with a high-precision ball bearing, which effectively reduces transmission resistance and wear and extends the service life of the equipment; The rotary drive can be a variable frequency geared motor, a servo motor, etc., and its output shaft is rigidly connected to the feeding shaft 8 through a coupling. A groove 119 is provided along the length of the bottom of the main board 103. This groove is a structure on the main board 103 for accommodating the teeth 118, ensuring that the teeth 118 are protected and can effectively mesh with the drive gear 9. The depth and width of the groove 119 should match the size of the teeth 118 and leave an appropriate gap to facilitate the installation of the teeth 118 and smooth meshing with the drive gear 9.

[0055] In some embodiments, the head wheel spindle of the bucket elevator 100 is equipped with an encoder, and the bottom hopper 2 is equipped with a sensor for detecting whether the bucket 12 has reached a preset position.

[0056] The bucket elevator 100 is equipped with an encoder on its head wheel spindle for real-time monitoring of the rotation angle and speed of the head wheel spindle. By processing the pulse signals or absolute position information output by the encoder, the running speed of the chain or belt 11 of the bucket elevator 100 and the current position of each bucket 12 can be accurately calculated.

[0057] Meanwhile, a sensor is installed in the bottom hopper 2 to detect whether the hopper 12 has reached a preset position. This sensor is used to detect whether the hopper 12 has moved to a predetermined key position during the operation of the bucket elevator 100. These sensors are typically installed at specific points in the bottom hopper 2, corresponding to the movement path of the hopper 12. Their detection signals serve as direct confirmation of the hopper 12's position and can be used to calibrate encoder data or as a direct command to initiate the loading action of the swing loading mechanism 1.

[0058] The controller continuously reads the encoder pulse / absolute position value to establish a position timing model for all hoppers 12. It tracks in real time which position each hopper 12 has reached on the elevator and how much travel is left to the preset station. When the encoder calculates that the target hopper is about to reach the preset position, and the bottom hopper 2 sensor detects the hopper's arrival confirmation (dual verification to prevent false triggering), the controller immediately locks the current hopper number and position. Based on the hopper 12 arrival signal and real-time linear velocity, the controller outputs switch / analog commands to the drive motor of the swing mechanism. It controls the swing start, swing angle, swing dwell time, and reset timing according to the preset timing, matching the hopper running speed to achieve hopper arrival → synchronous swing to receive / unload material → hopper departure → automatic mechanism reset.

[0059] Based on these precise position feedbacks, the control system can achieve fine control over the movement of the swing feeding mechanism 1, ensuring that the arc-shaped receiving plate of the swing feeding mechanism 1 can accurately correspond to the hopper 12 and convey materials when the hopper 12 moves to the optimal loading position.

[0060] In some embodiments, the upper end of the swing arm 101 is fixedly connected to the bushing 102, and the bushing 102 is rotatably connected to the fixing ring on the side wall of the bottom chamber 2 through a bearing seat, and the center of the fixing ring coincides with the axis of the tail wheel 10.

[0061] Specifically, the upper end of the swing arm 101 is fixedly connected to the bushing 102. The bushing 102 is typically a cylindrical sleeve, and the connection is achieved by welding. The bushing 102 is rotatably connected to a fixed ring on the side wall of the bottom chamber 2 via a bearing housing. A bearing (e.g., a rolling bearing or a sliding bearing) is installed between the bushing 102 and the fixed ring. Through its internal rolling elements or lubricating film, the swing friction of the swing arm 101 is minimized, thereby reducing energy loss and improving rotational sensitivity.

[0062] By setting a fixed ring, the axis of swing of the swing arm 101 can be aligned with the axis of rotation of the tail wheel 10 without causing any interference to the operation of the tail wheel 10, thus ensuring that the swing feeding mechanism 1 and the bucket elevator 100 move in sync.

[0063] In some embodiments, the main body 103 at the feed inlet 106 is a wedge-shaped structure, with its bottom surface fitting against the arc-shaped base plate and its top surface being inclined.

[0064] The main body 103 at the feed inlet 106 is designed as a wedge structure. This wedge structure means that in the feed inlet 106 area, the main body 103 has a gradually thinning or inclined geometric shape to optimize the introduction of materials and the cooperation with the arc-shaped bottom plate. The top surface of the main body 103 at the feed inlet 106 is inclined, which guides the materials to smoothly enter the interior of the feed inlet 106.

[0065] In this regard, such as Figure 1 As shown, this application further proposes a digitalized processing workshop, including the above-mentioned rice processing equipment, for lifting and conveying rice.

[0066] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
