Description

Technical Field

[0001] This invention relates to the field of agricultural product production, processing, and conveying equipment, and in particular to an automated feeding device based on agricultural product production and processing. Background Technology

[0002] In the large-scale agricultural product processing industry, automated feeding devices are the core equipment connecting various processing steps. They are widely used in the conveying operations of fruits, vegetables, grains, and fresh produce. Currently, conventional agricultural product feeding equipment on the market still has many technical shortcomings and is difficult to adapt to the needs of modern continuous production.

[0003] The width of the feeding channel is mostly a fixed size or requires manual adjustment. When processing agricultural products of different particle sizes and shapes, the machine needs to be stopped for adjustment. Even if some patents propose a width adjustment function, the adjustment mechanism still requires an independent drive component. During the process of agricultural products falling from the hopper to the conveyor belt, they are easily broken due to impact from height and squeezing between particles. Existing buffer solutions are mostly single-point protection, which is difficult to cope with continuous impact and stacking squeezing during multi-stage falling. There is a lack of graded buffer linkage structure. After the material falls into the conveyor belt, it is mostly distributed in a pile, which leads to uneven feeding in subsequent processing and local overload of the conveyor belt. Existing material uniformity solutions generally rely on independent drive mechanisms, and the functional components lack mechanical linkage. Existing feeding devices have technical defects in three aspects: material adaptability, anti-breakage protection, and conveying uniformity. The mechanical linkage between the functional components is weak, making it difficult to achieve multi-functional synergy.

[0004] Therefore, this application provides an automated feeding device based on agricultural product production and processing to meet the demand. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an automated feeding device based on agricultural product production and processing, so as to solve the problems of low adaptability of existing feeding devices to agricultural products of different specifications, high material breakage and damage rate, uneven stacking, and poor coordination between functional components.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: An automated feeding device for agricultural product production and processing includes a conveyor belt. Both ends of the conveyor belt are equipped with drive structures for its operation. A grading, buffering, and diverting component is located above one side of the conveyor belt, and a follow-up adjustment component is located at the bottom of the grading, buffering, and diverting component. A floating crushing and leveling component is also located above the conveyor belt. The grading, buffering, and diverting component is used to buffer the impact force of falling agricultural products at each stage and divert the material. The follow-up adjustment component is used to adaptively adjust its opening based on the operating power of the drive structure, adapting to the conveying of materials of different specifications. The floating crushing and leveling component is located to the side of the grading, buffering, and diverting component and the follow-up adjustment component. The floating crushing and leveling component is driven by the drive structure and is used to gently crush, disperse, and level the material on the conveyor belt.

[0007] Optionally, the drive structure includes a drive motor and a rotating roller, the output end of the drive motor is connected to the rotating roller for transmission, and the rotating roller is rotatably engaged with the conveyor belt.

[0008] Optionally, the graded buffer diversion assembly includes a discharge housing 1, the top of which is provided with a discharge port, and the interior of the discharge housing 1 is provided with a buffer plate 1, a buffer plate 2 and a buffer plate 3 arranged obliquely from top to bottom.

[0009] Optionally, the upper surfaces of buffer plate one, buffer plate two, and buffer plate three are each provided with a plurality of diversion ribs, and an elastic buffer layer is laid between two adjacent diversion ribs. Buffer plate one, buffer plate two, and buffer plate three receive the falling material in stages. The falling momentum of the material is consumed by the multi-stage inclined plate surface, and the surface elastic buffer layer absorbs the residual impact. The diversion ribs are used to prevent material accumulation and divert and guide the material.

[0010] Optionally, the tilt angles of buffer plate one, buffer plate two, and buffer plate three increase sequentially, and the spacing between the buffer plate one, buffer plate two, and buffer plate three decreases sequentially.

[0011] Optionally, the follow-up adjustment component includes a centrifugal speed regulator. A bevel gear set is provided between one end of the rotating roller in the drive structure and the centrifugal speed regulator for driving the centrifugal speed regulator to work. The centrifugal speed regulator is fixedly connected to a moving plate. A connecting plate is fixedly connected to the side of the moving plate. Two linkage rods are fixedly connected to the connecting plate.

[0012] Optionally, the follow-up adjustment assembly further includes a second feeding housing, on which an adjustment plate is slidably mounted. The side of the adjustment plate is fixedly connected to one end of the linkage rod, and a discharge port is provided at the bottom of the second feeding housing.

[0013] Optionally, the rotating roller rotates synchronously with the drive motor and drives the centrifugal speed regulator through the bevel gear set. The faster the conveyor belt runs, the larger the opening of the adjusting plate driven by the centrifugal speed regulator and the linkage rod, which is suitable for the passage of large-sized materials. The slower the conveyor belt runs, the smaller the opening of the adjusting plate, which is suitable for the passage of small-sized materials.

[0014] Optionally, the floating compaction and equalization assembly includes two symmetrically arranged elastic support arms. The tops of the two elastic support arms are rotatably connected to a rotating shaft. A compaction roller is fixedly sleeved on the outside of the rotating shaft. The rotating shaft is connected to the output shaft of a drive motor via a transmission belt. The drive motor drives the compaction roller to rotate in the opposite direction at a low speed via the transmission belt. The elastic support arms enable the compaction roller to adapt to the material height.

[0015] Optionally, the outer wall of the rolling roller is provided with several sets of flexible material-distributing teeth, and a uniform material trough is formed between two adjacent sets of material-distributing teeth. The flexible material-distributing teeth on the rolling roller gently disperse and flatten the material accumulated on the conveyor belt, and the uniform material trough guides the material to form a uniform thin layer for orderly conveying on the conveyor belt.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, a graded buffer and diversion component is set up, adopting a three-stage inclined buffer plate combination structure, combined with an elastic buffer layer and diversion ribs. The overall protection and conveying performance is outstanding. The inclination angle and plate spacing of the three-stage buffer plates change progressively, which can consume the kinetic energy of agricultural products falling layer by layer, allowing the impact force of falling to continuously decay. This reduces the problem of bumping and breaking of fragile materials such as fruits and vegetables and fresh fruits from the source, effectively reducing production losses and improving the yield rate. The elastic buffer layer on the surface of the buffer plate can absorb residual impact force and vibration, further enhancing the damage prevention effect. The diversion ribs divide the feeding area into multiple channels, which can not only break up clumps of materials and prevent bridging and blockage at the feeding port, ensuring the continuity of feeding, but also evenly divert and guide materials to avoid local material swarming. The component has a compact structure and is wear-resistant, and can be adapted to various agricultural products with different weights and different rolling speeds. The feeding rhythm is smooth and controllable, which greatly improves the stability and smoothness of the feeding process.

[0017] By incorporating a follow-up adjustment component, fully automatic opening adjustment is achieved through mechanical transmission, eliminating the need for manual operation and electrical control systems. It is well-suited to the complex working conditions of agricultural product processing workshops, characterized by high dust and humidity. It boasts strong anti-interference capabilities and reliable operation. The system utilizes the power of the rotating rollers to drive a centrifugal speed regulator via a bevel gear set, converting belt speed into mechanical displacement. Higher belt speeds result in a larger opening for the adjusting plate, allowing for smooth transport of large-sized materials and preventing jamming. Conversely, lower speeds result in a smaller opening, limiting the movement of small materials and preventing leakage. The entire mechanical transmission structure offers precise transmission and timely response. Components such as the moving plate and linkage rods experience uniform force, making them resistant to deformation and jamming during long-term reciprocating operation. This component eliminates the need for additional sensors, servo motors, and control systems, simplifying the equipment structure while reducing manufacturing costs and potential failure points. One device can accommodate various specifications of agricultural products, offering strong versatility and effectively reducing equipment debugging and replacement frequency, thus improving overall production efficiency.

[0018] By setting up a floating compaction and equalization component, the component relies on the elastic support arm, flexible feeding teeth, and equalization trough to complete the equalization operation. It is specifically adapted to agricultural products with soft texture and fragile surface. The compaction roller rotates in reverse at low speed, and the flexible feeding teeth gently break up the piled materials, without squeezing or scratching the agricultural products, thus fully ensuring the quality of the materials. The elastic support arm has floating self-adaptive capability, which can adjust the height of the compaction roller in real time according to the thickness of the material layer, so that the roller body and the material are always in flexible contact, the pressure is evenly distributed, and local heavy pressure or idle running is avoided, resulting in good uniformity of equalization effect. The equalization trough between the feeding teeth can guide and sort the scattered materials, and organize the materials into a continuous material layer of uniform thickness, providing stable feeding conditions for subsequent cleaning, sorting, cutting and other processes. The power is transmitted by a drive belt, which has good shock absorption and noise reduction effect, resulting in a better workshop working environment. The components are easy to disassemble and assemble, and the later maintenance is simple. It can complete the leveling and equalization operation stably for a long time, which helps the entire processing production line operate efficiently. Attached Figure Description

Detailed Implementation

[0021] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention.

[0022] like Figures 1 to 11As shown, an embodiment of the present invention provides an automated feeding device for agricultural product production and processing, including a conveyor belt 1. Both ends of the conveyor belt 1 are equipped with drive structures 2 for driving its operation. A graded buffer diversion component 3 is arranged above one side of the conveyor belt 1, and a follow-up adjustment component 4 is arranged at the bottom of the graded buffer diversion component 3. A floating crushing and leveling component 5 is also arranged above the conveyor belt 1. The graded buffer diversion component 3 is used to buffer the impact force of falling agricultural products step by step and divert the material. The follow-up adjustment component 4 is used to achieve adaptive adjustment of the opening based on the operating power of the drive structure 2 to adapt to the conveying of materials of different specifications. The floating crushing and leveling component 5 is arranged on the side of the graded buffer diversion component 3 and the follow-up adjustment component 4. The floating crushing and leveling component 5 is driven by the drive structure 2 and is used to gently crush, disperse and level the material on the conveyor belt 1. This device integrates multiple functions such as feeding buffer, material diversion, adaptive adjustment of the diameter, and flexible leveling and leveling into one unit. All functional components share a single drive system, eliminating the need for separate power mechanisms, sensors and electronic control adjustment modules. The overall layout is compact and reasonable, occupying little space in the production workshop. For agricultural products such as fruits, vegetables, grains, and fresh produce that are easily damaged and vary in shape and size, this device can continuously complete the entire process of feeding, buffering, size matching, and uniform material conveying, replacing traditional segmented feeding equipment, simplifying the production line layout. At the same time, the operation of each component works in coordination and synchronization, ensuring a smooth and continuous feeding process. This effectively improves the overall conveying efficiency and automation level of the agricultural product processing production line. It is highly versatile and can be widely used in various primary and deep processing scenarios for agricultural products.

[0023] like Figure 6 As shown, the drive structure 2 includes a drive motor 201 and a rotating roller 202. The output end of the drive motor 201 is connected to the rotating roller 202 for transmission. The rotating roller 202 rotates in conjunction with the conveyor belt 1. The drive motor 201 and the rotating roller 202 are used as the core power output unit. The transmission form is simple and the mechanical transmission loss is low. On the one hand, the conventional roller pressing transmission method of the rotating roller 202 and the conveyor belt 1 is mature and stable, which can provide a continuous and stable driving force for the conveyor belt 1, ensuring that the belt runs at a uniform speed and avoiding the problems of material deviation and accumulation due to belt start-stop and speed fluctuation. On the other hand, as the only power source of the whole machine, the drive structure 2 can simultaneously provide operating power for the grading buffer diversion component 3, the follow-up adjustment component 4, and the floating rolling and uniform material component 5, realizing the linkage operation of the whole equipment. Compared with the scheme of multiple motors driving separately, this design reduces the number of motors, circuits and control components used, which not only reduces the equipment procurement cost and the probability of circuit failure, but also simplifies the daily inspection, maintenance and upkeep work, extends the overall service life of the equipment, and is more suitable for the production needs of factories for long-term continuous operation.

[0024] like Figures 3 to 5As shown, the graded buffer and diversion assembly 3 includes a discharge housing 301, with a discharge port 302 at the top. Inside the discharge housing 301, buffer plates 303, 304, and 305 are arranged obliquely from top to bottom. Several diversion ribs 306 are provided on the upper surfaces of buffer plates 303, 304, and 305. An elastic buffer layer 307 is laid between adjacent diversion ribs 306. Buffer plates 303, 304, and 305 successively receive falling materials, consuming the falling momentum of the materials through the multi-stage inclined plate surfaces, in conjunction with the table... The elastic buffer layer 307 absorbs residual impact, and the diversion ribs 306 are used to prevent material accumulation and divert and guide the material. The inclination angles of buffer plate one 303, buffer plate two 304 and buffer plate three 305 increase sequentially, and the spacing between the plates of buffer plate one 303, buffer plate two 304 and buffer plate three 305 decreases sequentially. When agricultural products fall from the high discharge port 302, they have a large impact force. This device adopts a three-stage stepped buffer plate to receive the material step by step. With the structural design of increasing inclination angle and decreasing plate spacing, the falling height of the material can be gradually reduced and the falling momentum can be decomposed to achieve the gradual attenuation of impact force. The elastic buffer layer 307 on the surface of the board can further absorb residual vibration and impact force. For fruits and vegetables with crisp peels and easily damaged flesh, it can effectively prevent problems such as bumps, cracks, and scratches, significantly reducing material loss during the production process and improving the yield of finished products. The diversion ribs 306 on the board divide the feeding area into multiple independent channels, which can break up clumps and stacks of materials, avoid the phenomenon of material accumulation causing blockage and bridging at the feeding port 302, and ensure the continuity of feeding. At the same time, the diversion ribs 306 guide the materials, so that the materials are evenly distributed into the subsequent structure, avoiding local material clumping. The gradually changing inclination angle and spacing can adapt to agricultural products with different weights and different rolling speeds. The material descent rhythm is smooth and controllable. It will not cause secondary impact due to the board surface being too steep, nor will it cause material stagnation due to the board surface being too gentle, and the feeding stability is significantly improved.

[0025] like Figures 6 to 9As shown, the follow-up adjustment assembly 4 includes a centrifugal speed regulator 401. A bevel gear set 203 is provided between one end of the rotating roller 202 in the drive structure 2 and the centrifugal speed regulator 401 to drive the centrifugal speed regulator 401. A moving plate 402 is fixedly connected to the centrifugal speed regulator 401. A connecting plate 403 is fixedly connected to the side of the moving plate 402. Two linkage rods 404 are fixedly connected to the connecting plate 403. The follow-up adjustment assembly 4 also includes a second feeding housing 405, on which a sliding assembly is mounted. There is an adjusting plate 406, the side of which is fixedly connected to one end of the linkage rod 404. The bottom of the feeding housing 405 is provided with a discharge port 407. The rotating roller 202 rotates synchronously with the drive motor 201, and drives the centrifugal speed regulator 401 through the bevel gear set 203. The faster the conveyor belt 1 runs, the larger the opening of the adjusting plate 406 driven by the centrifugal speed regulator 401 through the moving plate 402 and the linkage rod 404, which is suitable for the passage of large-sized materials. The slower the conveyor belt 1 runs, the larger the opening of the adjusting plate 406. The smaller the opening of plate 406, the more suitable it is for small-sized materials to pass through. Utilizing the mechanical power of roller 202, the centrifugal speed regulator 401 is driven by bevel gear set 203. The diameter adjustment is completed entirely by the machine's own operating power, without the need for manual adjustment or the addition of photoelectric sensors, servo motors, control systems, or other electrical control components. This achieves true mechanical adaptive adjustment, with strong anti-interference capabilities. It is not prone to failure in humid and dusty agricultural product processing workshops. The opening of plate 406 is linked to the speed of conveyor belt 1 in real time. When the belt is running at high speed, it corresponds to the conveying of large-volume agricultural products. Plate 406 automatically opens the passage diameter to prevent large-sized materials from getting stuck. When the conveyor belt 1 is running at low speed, it corresponds to the conveying of small-volume, fine-particle agricultural products. Plate 406 automatically closes the diameter to effectively prevent fine materials from scattering or leaking from the side. This achieves multiple uses with one machine, which can meet the conveying needs of agricultural products of different sizes and shapes, reducing equipment replacement and debugging time.

[0026] like Figures 10 to 11As shown, the floating compaction and leveling assembly 5 includes two symmetrically arranged elastic support arms 501. The tops of the two elastic support arms 501 are rotatably connected to a rotating shaft 502. A compaction roller 504 is fixedly sleeved on the outside of the rotating shaft 502. The rotating shaft 502 is connected to the output shaft of a drive motor 201 via a transmission belt 503. The drive motor 201 drives the compaction roller 504 to rotate in the opposite direction at a low speed via the transmission belt 503. The elastic support arms 501 allow the compaction roller 504 to adapt to the material height. Several sets of flexible material-distributing teeth 505 are provided on the outer wall of the compaction roller 504. A leveling groove 506 is formed between two adjacent sets of material-distributing teeth. The flexible material-distributing teeth 505 on the compaction roller 504 gently disperse and level the material accumulated on the conveyor belt 1. The leveling groove 506 guides the material, allowing it to form a uniform thin layer and be conveyed in an orderly manner on the conveyor belt 1. The compaction roller 504 adopts a reverse low-speed rotation working mode, combined with the flexible material-distributing teeth 505, abandoning the traditional hard compaction... The scraping structure features gentle and smooth material-dispersing action, only breaking up and flattening accumulated or raised materials. It avoids squeezing, puncturing, or crushing damage to soft, fragile agricultural products, structurally ensuring the appearance and quality of the materials. The symmetrically arranged elastic support arms 501 have elastic extension and retraction capabilities and can float up and down. They can adjust the height of the crushing rollers 504 in real time according to the thickness of the material accumulation on the conveyor belt 1, ensuring flexible contact between the crushing rollers 504 and the material surface throughout the process. The pressure distribution is uniform, preventing problems such as local heavy pressure or idle running. It is suitable for conveying materials with uneven thickness. The material equalization grooves 506 formed between adjacent flexible material-dispersing teeth 505 have a guiding and combing function, which can comb the scattered materials into a continuous, uniform thin layer of consistent thickness. This makes the materials neatly arranged on the conveyor belt 1. The neat material state can provide stable feeding conditions for subsequent processing steps such as cleaning, sorting, cutting, and packaging, effectively improving the processing accuracy and production quality of the entire production line.

[0027] The working principle of the technical solution provided by this invention is as follows: This invention is an automated feeding device for agricultural product production and processing. The whole machine is powered by the same drive structure 2, and the various functional components work together to complete the entire process of multi-stage buffer feeding, follow-up diameter adjustment, and floating flexible uniform material conveying of agricultural products in sequence. The overall operation is smooth and highly automated.

[0028] When the device is running, the drive motor 201 is started. The output end of the drive motor 201 drives the rotating roller 202 to rotate synchronously. The rotating roller 202 and the conveyor belt 1 form a roller pressing transmission cooperation, thereby driving the conveyor belt 1 to perform continuous cyclic conveying motion. This device uses the drive motor 201 as the only power source. On the one hand, it directly drives the conveyor belt 1 to complete the material conveying. On the other hand, through the bevel gear set 203, transmission belt 503 and other transmission components, the power is transmitted to the follow-up adjustment component 4 and the floating rolling and uniform material component 5 respectively, so as to realize the synchronous operation of all mechanisms of the machine and ensure the uniformity of the action sequence of each process. No additional independent power equipment is required.

[0029] Agricultural products are fed into the device through the feeding port 302 at the top of the feeding shell 301. The material first falls onto the surface of the buffer plate 303. The three-stage buffer plates arranged at an incline form a stepped material falling channel, which gradually consumes the kinetic energy generated by the falling material. Since the inclination angle of the buffer plate 303, the buffer plate 304, and the buffer plate 305 increases from top to bottom, and the distance between the plates decreases from top to bottom, the vertical impact force of the material falling from a height is decomposed layer by layer. The first-stage buffer plate 303 receives the initial impact of the falling material, initially reducing the falling speed and falling height of the material. The material rolls down along the inclined surface of the buffer plate 303 to the buffer plate 304, where the kinetic momentum is consumed again. Finally, the material slides down to the buffer plate 305. At this time, the falling height and falling speed of the material have been greatly reduced, and the vertical impact force is in a state of gradual decay.

[0030] The upper surfaces of the three buffer plates are all covered with elastic buffer layers 307, which can further absorb the residual impact and vibration generated by the rolling and collision of materials, and avoid problems such as skin damage and cracking of agricultural products due to rigid impact. At the same time, the diversion ribs 306 evenly arranged on the surface of the buffer plates divide the feeding area into multiple independent feeding channels. On the one hand, they can break up the piled and clumped materials, prevent materials from lingering, bridging or blocking on the surface of the buffer plates, and ensure the continuity of feeding. On the other hand, they can divert and guide the materials, so that the materials are evenly distributed and avoid local material concentration, so as to stably supply the next stage follow-up adjustment component 4.

[0031] After being sorted by the graded buffer diversion component 3, the material falls into the lower feeding shell 405 and finally falls onto the surface of the conveyor belt 1 through the discharge port 407 at the bottom of the feeding shell 405. The material passage width inside the feeding shell 405 is automatically controlled by the adjusting plate 406. The opening of the adjusting plate 406 is mechanically adjusted according to the running speed of the conveyor belt 1.

[0032] The rotating roller 202 rotates continuously under the drive of the drive motor 201. One end of the rotating roller 202 completes power steering and speed change through the bevel gear set 203, thereby driving the centrifugal speed regulator 401 to work synchronously. The centrifugal speed regulator 401 converts the rotation speed signal of the rotating roller 202 into mechanical linear motion. When the production condition requires a large conveying flow and large-sized agricultural products, the speed of the drive motor 201 increases, the speed of the conveyor belt 1 increases, the speed of the rotating roller 202 increases synchronously, and the centrifugal force inside the centrifugal speed regulator 401 increases accordingly, pushing the moving plate 402 to form a lateral displacement. The moving plate 402 drives the two linkage rods 404 to move synchronously through the connecting plate 403. The linkage rods 404 further pull the adjusting plate 406, which is slidably assembled on the second feeding housing 405, to move outward, increasing the material opening inside the second feeding housing 405, ensuring that large-volume and large-sized agricultural products can pass smoothly, and effectively preventing material jamming and blockage.

[0033] When the conveying flow rate decreases and small granular agricultural products are conveyed, the speed of the drive motor 201 decreases, the speed of the conveyor belt 1 slows down, the speed of the roller 202 decreases, the centrifugal force inside the centrifugal speed regulator 401 decreases, and all components reset in reverse, pulling the adjustment plate 406 inward to reduce the material opening. The smaller material opening width can limit and block small agricultural products, preventing materials from scattering or leaking from both sides of the outlet 407. The entire adjustment process is driven entirely by the equipment's own operating power, requiring no manual intervention, no external electrical control system, and no detection components. It can adaptively match the passage width of different specifications of agricultural products in real time according to the conveying speed, realizing automated diameter adjustment.

[0034] After the material falls from the discharge port 407 of the follow-up adjustment component 4 onto the conveyor belt 1, it is conveyed forward with the conveyor belt 1 and enters the working area of ​​the floating crushing and leveling component 5 in sequence. The drive motor 201 drives the rotating shaft 502 and the crushing roller 504 outside the rotating shaft 502 to rotate in the opposite direction at low speed through the transmission belt 503. The rotation direction of the crushing roller 504 is opposite to the conveying direction of the conveyor belt 1. When the material on the conveyor belt 1 moves forward, it first contacts the flexible material-pushing teeth 505 on the outer wall of the crushing roller 504. The flexible material-pushing teeth 505 rely on the gentle force of the low-speed reverse rotation to gradually disperse and flatten the locally accumulated and raised material on the belt to the sides and rear, completely breaking up the material clumps. At the same time, the flexible material-pushing teeth will not squeeze or scratch the fragile agricultural products, ensuring the integrity of the material.

[0035] The two ends of the roller 504 are mounted on the top of symmetrically arranged elastic support arms 501. The elastic support arms 501 have elastic deformation and up-and-down floating capabilities, which can adapt to the accumulation thickness of the material on the conveyor belt 1 in real time. When the material layer is too thick, the material pushes up the roller 504 and the elastic support arms 501 extend upward elastically. When the material layer is too thin, the elastic support arms 501 rely on their own elasticity to reset, so that the roller 504 always fits the material surface. This floating structure makes the contact pressure of the roller 504 on the material uniform and stable, and there will be no problems such as local heavy pressure or idling. The uniformity of the material operation is good.

[0036] Two adjacent sets of flexible feeding teeth 505 form an integrated material equalization trough 506. During the feeding process, the scattered materials are organized into a continuous thin layer with uniform thickness and regular arrangement under the guidance and sorting effect of the material equalization trough 506. Finally, the material is output smoothly with the conveyor belt 1. The regular material shape can meet the feeding requirements of various agricultural product processing processes such as subsequent cleaning, sorting, cutting, and packaging, and ensure the stable operation of the entire production line.

[0037] Agricultural products enter the grading, buffering, and diversion assembly 3 through the feeding port 302. After being unloaded step by step by the three-stage buffer plates, the elastic buffer layer 307 absorbs shock, and the diversion ribs 306 divert and prevent blockage, the products smoothly enter the follow-up adjustment assembly 4. The follow-up adjustment assembly 4 automatically adjusts the material opening according to the speed of the conveyor belt 1 to adapt to the current material specifications. The material falls onto the conveyor belt 1 through the discharge port 407. The conveyor belt 1 drives the material forward and enters the floating crushing and leveling assembly 5 area. The crushing rollers 504 rotating in the opposite direction, the flexible material-pulling teeth 505 and the leveling trough 506 work together to complete the dispersion, leveling and guiding operations, and finally form a uniform material layer that is continuously delivered, completing a complete set of automated feeding cycles. All mechanisms of the whole machine operate in conjunction to realize the fully automated operation of agricultural products from feeding to conveying.
