Abstract
Description
Technical Field
[0001] This invention relates to the technical field of seed equipment, specifically to a seed low-damage conveying and uniform feeding control device. Background Technology
[0002] Seeds are a fundamental material in agricultural production, and their sowing quality directly affects crop emergence rate and uniform growth. In mechanized sowing and centralized seed processing, seeds are typically transported from storage silos to sowing or distribution mechanisms via conveying devices, with a degree of metering and uniform feeding control achieved during this process. Existing seed conveying methods mainly include screw conveyors, belt conveyors, pneumatic conveyors, and vibrating conveyors.
[0003] In existing technologies, the discharge port of the storage bin often adopts a simple gate or a fixed opening structure, which makes it difficult to effectively regulate and continuously and uniformly control the seed flow. This results in a disordered flow state with instantaneous concentration or intermittent interruption of the seed flow when it enters the conveying mechanism. Therefore, the following disadvantages exist: the seed flow fluctuates greatly and the uniformity is poor during the feeding process, which reduces the overall stability and consistency of the feeding. Summary of the Invention
[0004] The purpose of this invention is to provide a seed low-damage conveying and uniform feeding control device to solve the problem of large flow fluctuations and poor uniformity of seeds during the feeding process, which reduces the overall stability and consistency of the feeding.
[0005] To achieve the above-mentioned objectives, the present invention employs the following technical solution: a seed low-damage conveying and uniform feeding control device, comprising a storage bin, the storage bin being disposed above a frame, two support frames fixed to the front and rear sides of the outer wall of the storage bin, the bottom ends of the support frames being connected to the top surface of the frame, a conveyor belt being provided inside the frame, a sealing cover being bolted to the top surface of the storage bin, a metering box being fixed to the bottom surface of the storage bin, a feed hole being provided on the top surface of the metering box, and movable grooves being provided on the front and rear sides of the inner wall of the metering box. The internal structure contains a rotatable metering column. The front and rear ends of the metering column are fixed with rotating shafts. Both rotating shafts are rotatably mounted in two movable slots. Metering slots are provided on the top, bottom, left, and right sides of the metering column. A motor is fixed to the front of the metering box, and the motor's output shaft passes through the metering box and connects to the rotating shafts on the front. A discharge hole is provided on the bottom of the metering box. A PLC controller is fixed to the front of the frame. Two triangular plates are fixed to the top of the metering box. The conveyor belt and motor are electrically connected to the PLC controller.
[0006] Preferably, an arc-shaped plate is fixed to the bottom surface of the metering box, two side plates are fixed to the inner wall of the arc-shaped plate, a guide plate is fixed to the right side of the arc-shaped plate, and the top surface of the guide plate is inclined.
[0007] Preferably, the top surface of the frame is fixed with two fixing plates, and the inner side of each of the two fixing plates is fixed with a flexible baffle.
[0008] Preferably, an installation plate is fixed between the two fixing plates, and a flat plate is movably provided below the installation plate, the bottom of the flat plate being arc-shaped.
[0009] Preferably, the top surface of the mounting plate has a threaded hole, and a screw is threaded into the threaded hole. The top surface of the flat plate has a rotating groove, and a rotating block is fixed to the bottom end of the screw. The rotating block is rotatably disposed in the rotating groove.
[0010] Preferably, the top surface of the mounting plate has two limiting holes, and the top surface of the flat plate has two limiting shafts fixed thereon, both of which are slidably inserted into the two limiting holes.
[0011] Preferably, a turntable is fixed to the top of the screw, and a plurality of protrusions are fixed to the outer wall of the turntable.
[0012] Preferably, an observation hole is provided on the right side of the outer wall of the storage bin, and glass is fixed inside the observation hole.
[0013] Compared with existing technologies, the seed low-damage conveying and uniform feeding control device that adopts the above technical solution has the following beneficial effects: I. During use, as the seeds move towards the bottom of the storage hopper, their flow direction is reconstructed under the bidirectional inclined plane guidance of the triangular plate. The originally randomly falling particle flow is gradually guided into a directional flow state that converges along the inclined plane, creating a stable and continuous confluence effect at the bottom of the storage hopper, thus continuously and centrally conveying the seeds towards the feed port area. During this confluence process, the feed port, as a quantitative inlet structure, ensures that the seeds entering the quantitative box are in a continuous but restricted entry state, avoiding the situation of instantaneous large flow impacting the quantitative mechanism, thereby improving the subsequent metering stability. After entering the quantitative box, the seeds gradually enter the quantitative grooves on the outer periphery of the quantitative column under the action of gravity and structural guidance. Since the quantitative grooves are multiple equiangularly distributed volumetric structures, when the quantitative column is stationary or rotating at low speed, the quantitative grooves are successively in the upper loading area, the side transition area, and the lower unloading area. When the metering trough rotates to the upper position, the seeds automatically enter the trough under gravity and form a stable filling state under the constraint of the trough wall. This filling process is a gradual, stacking filling, ensuring that the seed volume in a single metering trough remains relatively consistent, thus achieving volumetric metering control. When the motor drives the rotating shaft through the output shaft to rotate the metering column at an angle, the filled metering trough gradually transitions from the upper position to the side position. During this process, the trough opening gradually deviates from the feeding area, ensuring that the filled seeds remain stable under gravity and do not prematurely leak out, thus achieving an integrated switching effect of loading and isolating. As the metering column continues to rotate, when the metering trough rotates to the lower position and forms a spatial alignment with the discharge hole, the seeds inside the trough are released as a whole under gravity, forming a metering process based on the volume of a single trough. This allows the seeds to be output from the metering box intermittently, periodically, and in equal volumes. The released seeds fall onto the conveyor belt surface in a relatively stable particle group form, achieving periodic and uniform feeding. Through the coordinated action of the storage bin, frame, support frame, conveyor belt, sealing cover, metering box, feed hole, movable groove, metering column, rotating shaft, metering groove, motor, discharge hole, PLC controller and triangular plate, the seed is released in a stable and periodic manner with equal volume, which transforms the disordered flow of traditional gate or fixed opening discharge into continuous and uniform feeding, thereby ensuring stable and consistent feeding. II. During use, the seeds released from the discharge port are initially in free fall. Due to their falling speed and kinetic energy, direct impact on the conveyor surface can easily cause particle breakage. When the seeds contact the curved plate, the curved surface structure causes a gradual change in the seed's velocity direction at the moment of contact, transitioning from a vertical impact state to a sliding state along the curved surface, thus achieving the first stage of impact energy release. Simultaneously, the side plates physically block the lateral diffusion trend of the seeds during their movement on the curved plate surface, keeping the seeds within a limited flow channel and preventing material loss due to bouncing or scattering. Subsequently, under the combined action of gravity and the curved surface guidance, the seeds enter the guide plate area. Because the top surface of the guide plate is designed with an inclined guiding structure, the seeds further transition from curved surface sliding to inclined surface sliding, thus achieving the second stage of velocity attenuation and direction correction. After the action of these two-stage buffer structures, the seeds finally enter the conveyor belt surface at a low impact speed, significantly reducing the impact load at the moment of contact with the conveyor belt, thereby effectively reducing the probability of seed skin breakage, embryo cracking, and mechanical damage. As the conveyor belt runs continuously inside the frame, the seeds move synchronously to the right due to the frictional force on the conveyor belt surface. During transport, due to the rolling and bouncing characteristics of the seeds, some seeds may exhibit lateral displacement when encountering vibration or local accumulation. At this point, the fixed plate structurally encloses the space on both sides of the conveyor belt, limiting the overall movement area of the seeds to the effective conveying width of the conveyor belt. The flexible baffle inside the fixed plate further provides flexible contact constraint, allowing the seeds to experience buffered rebound or sliding adjustment upon contact with the flexible baffle, rather than rigid collision. This prevents secondary damage caused by hard impacts and reduces jamming and accumulation. III. During use, when seeds enter the area covered by the flat-laying plate, they gradually enter the plate's coverage area under the inertia of the conveyor belt. Because the bottom of the flat-laying plate is designed with an arc shape, it exerts a gradual squeezing and guiding effect on the seed flow layer, causing the seed layer, which was originally uneven in thickness or in a state of accumulation, to gradually redistribute. In this process, seed particles form a dynamic flow layer between the space below the flat-laying plate and the surface of the conveyor belt. Through continuous squeezing and release cycles, the seeds gradually form a more uniform distribution. This effectively eliminates the accumulation or blank areas on the conveyor belt caused by concentrated material drop, thereby improving the overall uniformity of conveying. The operator drives the screw through a rotating turntable in the threaded hole, causing the screw to generate stable axial displacement, which further drives the rotating block to rotate synchronously in the rotating groove, thus achieving a composite conversion of rotation and linear motion. This composite motion ultimately causes the flat-laying plate to produce a continuously adjustable vertical height change relative to the mounting plate, allowing the distance between the flat-laying plate and the conveyor belt to be dynamically adjusted according to the actual seed particle size, accumulation thickness, and conveying flow rate. By adjusting this spacing, the degree of restriction and distribution of seeds in the flat area can be changed, gradually transitioning them from a localized accumulation state to a uniformly spread state. This enables adaptive uniform spreading control for different types or sizes of seeds, improving overall transport stability and applicability. IV. During use, when the paving board is raised and lowered under the drive of the screw, the limiting shaft slides axially within the limiting hole. This structure provides bidirectional guiding constraint for the paving board, ensuring it maintains a vertical movement trajectory during raising and lowering, and preventing structural displacement caused by uneven screw force or localized load. Simultaneously, this limiting structure can absorb some lateral disturbance force, maintaining a stable contact angle for the paving board during operation, thus ensuring consistent paving results. The operator manually rotates the turntable to drive the screw. Because the turntable's outer wall has several protrusions, these protrusions significantly increase the frictional contact area and force support points between the hand and the turntable, making it less prone to slippage or free-spinning during force application, thereby improving the stability and controllability of the rotational transmission. Furthermore, this structure makes the turntable rotation smoother and more continuous, facilitating fine-tuning control of the screw, thereby improving the accuracy and consistency of paving board height adjustment and preventing uneven seed paving due to adjustment deviations. The seed level inside the storage silo is visualized through an observation hole and glass, allowing operators to monitor seed level changes in real time during equipment operation. By observing the seed accumulation height and distribution within the silo, it's possible to determine if there is insufficient supply or a need for replenishment, thus completing the status assessment without disassembling the sealing cover. When the observation results show that the seed level inside the storage silo has dropped below a preset safety threshold, replenishment can be performed by opening the sealing cover. After replenishment, the sealing cover is then tightened again with bolts to restore the silo to a sealed state and allow operation to continue. Attached Figure Description

Detailed Implementation
[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0023] like Figures 1-4As shown, a seed low-damage conveying and uniform feeding control device includes a storage bin 1, which is positioned above a frame 2. Two support frames 3 are fixed to the front and rear sides of the outer wall of the storage bin 1. The bottom ends of the support frames 3 are connected to the top surface of the frame 2. A conveyor belt 4 is installed inside the frame 2. A sealing cover 5 is bolted to the top surface of the storage bin 1. A metering box 6 is fixed to the bottom surface of the storage bin 1. A feed hole 7 is opened on the top surface of the metering box 6. Movable grooves 8 are opened on the front and rear sides of the inner wall of the metering box 6. A metering column 9 is rotatably installed inside the metering box 6. The front and rear ends of the metering column 9 are fixed. A rotating shaft 10 is fixed, and two rotating shafts 10 are rotatably set in two movable slots 8. The top, bottom, left and right sides of the metering column 9 are provided with metering slots 11. The front side of the metering box 6 is fixed with a motor 12. The output shaft of the motor 12 passes through the metering box 6 and is connected to the rotating shaft 10 on the front side. The bottom side of the metering box 6 is provided with a discharge hole 13. The front side of the frame 2 is fixed with a PLC controller 14. The top side of the metering box 6 is fixed with two triangular plates 32. The conveyor belt 4 and the motor 12 are electrically connected to the PLC controller 14. The PLC controller 14 is a Siemens S7-200.
[0024] During use, the support frame 3 can support the storage bin 1 and fix it on the frame 2. After the equipment is started, the seeds in the storage bin 1 continue to move downward under the action of gravity and gradually form a natural flow state from top to bottom inside the storage bin 1. Due to the friction and mutual support between the seed particles, local stagnation or arching tends to occur during the downward movement.
[0025] As the seeds move toward the bottom of the storage bin 1, their flow direction is reconstructed under the bidirectional inclined plane guiding action of the triangular plate 32. The originally randomly falling particle flow is gradually guided into a directional flow state that converges along the inclined plane, so that the seeds form a stable and continuous confluence effect in the bottom area of the storage bin 1, thereby continuously and centrally conveying them toward the feed hole 7 area.
[0026] During this flow convergence process, the feed port 7 serves as a quantitative inlet structure, ensuring that the seeds entering the quantitative box 6 enter in a continuous but restricted manner, thus avoiding the situation where a large instantaneous flow rate impacts the quantitative mechanism and improving the subsequent metering stability.
[0027] After entering the quantitative box 6, the seeds gradually enter the quantitative groove 11 on the outer periphery of the quantitative column 9 under the action of gravity and structural guidance. Since the quantitative groove 11 is a volumetric structure with multiple equal angles, when the quantitative column 9 is stationary or rotating at low speed, the quantitative groove 11 is in the upper loading area, the side transition area and the lower unloading area in sequence.
[0028] When the quantitative trough 11 rotates to the upper region, the seeds automatically enter the trough under the action of gravity and form a stable filling state under the constraint of the trough wall. This filling process is a step-by-step stacking filling, so that the seed volume in a single quantitative trough 11 remains relatively consistent, thereby realizing volumetric quantitative control.
[0029] When the motor 12 drives the rotating shaft 10 through the output shaft to rotate the metering column 9 at an angle, the metering trough 11 that has been filled gradually transitions from the upper position to the side position. During this process, the opening of the trough gradually deviates from the feeding area, so that the filled seeds remain stable under the action of gravity and do not leak out prematurely, thereby achieving the integrated switching effect of filling and isolating.
[0030] As the metering column 9 continues to rotate, when the metering trough 11 rotates to the lower position and forms a spatial alignment with the discharge hole 13, the seeds inside the trough are released as a whole under the action of gravity, forming a metering process based on the volume of a single trough. This allows the seeds to be output from the metering box 6 in an intermittent, periodic, and equal volume manner. The released seeds fall onto the surface of the conveyor belt 4 in a relatively stable particle group form, achieving periodic and uniform feeding.
[0031] Through the coordinated action of the storage bin 1, frame 2, support frame 3, conveyor belt 4, sealing cover 5, metering box 6, feed hole 7, movable groove 8, metering column 9, rotating shaft 10, metering groove 11, motor 12, discharge hole 13, PLC controller 14 and triangular plate 32, the seed is released in a stable and periodic manner with equal volume, transforming the disordered flow of traditional gate or fixed opening discharge into continuous and uniform feeding, thereby ensuring stable and consistent feeding.
[0032] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, an arc-shaped plate 15 is fixed to the bottom surface of the metering box 6, two side plates 16 are fixed to the inner wall of the arc-shaped plate 15, a guide plate 17 is fixed to the right side of the arc-shaped plate 15, the top surface of the guide plate 17 is inclined, two fixing plates 18 are fixed to the top surface of the frame 2, and flexible baffles 19 are fixed to the inner side of the two fixing plates 18.
[0033] During use, the seeds released from the discharge hole 13 are in free fall initially. Due to their falling speed and kinetic energy, direct impact on the conveying surface can easily cause particle breakage. When the seeds contact the arc-shaped plate 15, the curved structure of the plate causes a gradual change in the velocity direction of the seeds upon contact, transitioning from a vertical impact state to a sliding state along the curved surface, thus achieving the first stage of impact energy release. Simultaneously, the side plate 16 physically blocks the lateral diffusion trend of the seeds during their movement on the surface of the arc-shaped plate 15, keeping the seeds within a limited flow channel and preventing material loss due to bouncing or scattering. Subsequently, under the combined action of gravity and the curved surface guidance, the seeds enter the area of the guide plate 17. Since the top surface of the guide plate 17 is set as an inclined guiding structure, the seeds further transition from curved surface sliding to inclined surface sliding, thus achieving the second stage of velocity attenuation and direction correction. After passing through a two-stage buffer structure, the seed finally enters the surface of the conveyor belt 4 at a low impact speed, which significantly reduces the impact load on the seed upon contact with the conveyor belt, thereby effectively reducing the probability of seed breakage, embryo cracking, and mechanical damage.
[0034] As the conveyor belt 4 runs continuously inside the frame 2, the seeds move synchronously to the right due to the frictional force on the surface of the conveyor belt 4. During the conveying process, due to the rolling and bouncing characteristics of the seed particles, some seeds may exhibit lateral displacement when encountering vibration or local accumulation. At this time, the fixed plate 18 structurally encloses the space on both sides of the conveyor belt 4, limiting the overall movement area of the seeds to the effective conveying width of the conveyor belt 4. The flexible baffle 19 further provides flexible contact constraint inside the fixed plate 18, causing the seeds to undergo buffered rebound or sliding adjustment when contacting the flexible baffle 19, rather than rigid collision, thereby avoiding secondary damage to the seeds due to hard impact and reducing jamming and accumulation.
[0035] like Figure 2 , Figure 6 and Figure 7 As shown, a mounting plate 20 is fixed between two fixed plates 18. A flat plate 21 is movably disposed below the mounting plate 20. The bottom of the flat plate 21 is arc-shaped. A threaded hole 22 is opened on the top surface of the mounting plate 20. A screw 23 is threadedly connected to the threaded hole 22. A rotating groove 24 is opened on the top surface of the flat plate 21. A rotating block 25 is fixed to the bottom end of the screw 23. The rotating block 25 is rotatably disposed in the rotating groove 24.
[0036] During use, when seeds enter the working area of the spreading plate 21, they gradually enter the coverage area of the spreading plate 21 under the inertia of the conveyor belt 4. Because the bottom of the spreading plate 21 is designed with an arc shape, it exerts a gradual squeezing and guiding effect on the seed flow layer, causing the seed layer, which was originally uneven in thickness or in a state of accumulation, to gradually redistribute. In this process, seed particles form a dynamic flow layer between the space below the spreading plate 21 and the surface of the conveyor belt 4. Through continuous squeezing and releasing cycles, the seeds gradually form a more uniform distribution. This effectively eliminates the accumulation or blank zones on the conveyor belt 4 caused by concentrated material drop, thereby improving the overall conveying uniformity.
[0037] The operator drives the screw 23 through the threaded hole 22 via a rotating turntable 28, causing the screw 23 to generate stable axial displacement. This further drives the rotating block 25 to rotate synchronously within the rotating groove 24, thus achieving a combined conversion of rotational and linear motion. This combined motion ultimately causes the flattening plate 21 to produce a continuously adjustable vertical height change relative to the mounting plate 20, allowing the spacing between the flattening plate 21 and the conveyor belt 4 to be dynamically adjusted according to the actual seed particle size, accumulation thickness, and conveying flow rate. By adjusting this spacing, the degree of restriction and distribution of seeds in the flattening area can be changed, gradually transitioning from a localized accumulation state to a uniformly spread state. This achieves adaptive and uniform flattening control for different types or sizes of seeds, improving overall conveying stability and applicability.
[0038] like Figures 1-3 , Figure 6 and Figure 7 As shown, the top surface of the mounting plate 20 has two limiting holes 26, the top surface of the flat plate 21 has two limiting shafts 27, and both limiting shafts 27 can be slidably inserted into the two limiting holes 26. The top end of the screw 23 is fixed with a turntable 28, and the outer wall of the turntable 28 is fixed with several protrusions 29. The right side of the outer wall of the storage bin 1 is provided with an observation hole 30, and the inside of the observation hole 30 is fixed with glass 31.
[0039] In this device, when the paving plate 21 is adjusted by lifting and lowering under the drive of the screw 23, the limiting shaft 27 slides axially within the limiting hole 26. This structure provides bidirectional guiding constraint for the paving plate 21, ensuring that it maintains a vertical movement trajectory during lifting and lowering, and preventing structural displacement caused by uneven force or localized off-center loading on the screw 23. Simultaneously, this limiting structure can also absorb some lateral disturbance forces, allowing the paving plate 21 to maintain a stable contact angle during operation, thereby ensuring consistent paving results.
[0040] The operator manually rotates the turntable 28 to drive the screw 23. Because the outer wall of the turntable 28 has several protrusions 29, these protrusions significantly increase the frictional contact area and force support points between the operator and the turntable 28, making it less prone to slippage or free-spinning during force application, thus improving the stability and controllability of the rotational transmission. Simultaneously, this structure allows for smoother and more continuous rotation of the turntable 28, facilitating fine-tuning control of the screw 23, thereby improving the accuracy and consistency of the height adjustment of the laying plate 21 and preventing uneven seed spreading due to adjustment deviations.
[0041] The seed level inside storage silo 1 is visualized through observation holes 30 and glass 31, allowing operators to monitor seed level changes in real time during equipment operation. By observing the seed accumulation height and distribution within storage silo 1, it is possible to determine if there is insufficient supply or a need for replenishment, thus completing the status assessment without disassembling the sealing cover 5. When the observation results show that the seed level inside storage silo 1 has dropped below a preset safety threshold, replenishment can be performed by opening the sealing cover 5. After replenishment, the sealing cover 5 is then secured again with bolts to restore the sealing state of storage silo 1 and allow it to continue operating.
[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
