Description

[Technical Field]

[0001] This invention relates to the field of harvesting and processing technology for long-stemmed crops, and more specifically to an intelligent dispersing device for pre-treatment of long-stemmed crops. [Background Technology]

[0002] In agricultural industrial chains such as sugarcane sugar production and comprehensive utilization of corn stalks, equipment such as leaf strippers and crushers are key processing links. However, existing harvesting equipment typically outputs long-stalked crops like sugarcane and corn stalks in bundles. When harvested crops (such as sugarcane and corn) are directly fed into the leaf stripper without effective dispersion, they often pile up and clog the inlet, resulting in poor or incomplete leaf stripping and potentially damaging the equipment, affecting production efficiency and processing quality. Current equipment faces the following technical bottlenecks: material accumulation problems – when bundled materials enter the processing equipment inlet, they easily accumulate and clog, leading to incomplete processing (such as leaf residue) or equipment overload and damage; low dispersion efficiency – preliminary dispersion of crops using mechanical or pneumatic devices has limited effect and cannot meet the high-efficiency operation requirements of leaf strippers, affecting subsequent processing quality.

[0003] Therefore, developing a pretreatment dispersion device that can dynamically adapt to various crops and improve dispersion effect is of great significance for upgrading the agricultural processing industry. [Summary of the Invention]

[0004] The purpose of this invention is to address the problem of poor processing results caused by piles of crops entering the inlet of existing sugarcane and other crop processing equipment. This invention provides an intelligent dispersion device for pre-treatment of long-stemmed crops, which disperses the piles of crops before feeding them into the processing equipment, thereby improving the processing effect and production efficiency of subsequent processes.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A smart dispersing device for pretreatment of long-stemmed crops, comprising:

[0007] The support frame, as an overall load-bearing structure, includes at least a frame, and an upper support frame and a lower support frame mounted on the frame;

[0008] P groups of flow guide frames are fixedly installed on the upper part of the support frame. Each group of flow guide frames consists of an upper inclined section and a lower inclined section connected to each other, and the upper inclined section and the lower inclined section form a flow guide angle of 110°-160°.

[0009] N sets of parallel guide rail devices, each set of guide rail devices includes a rail and a sliding component; the rail is set on the support frame and parallel to the downward inclined section, the length of the rail is less than or equal to the length of the downward inclined section, and N≥1;

[0010] A sliding connecting rod connects to N sliding components of N sets of guide rail devices;

[0011] M barrier fences are distributed and fixedly installed on the sliding connecting rod, where M≥2;

[0012] The sliding connecting rod lifting mechanism includes a first motor with bidirectional rotation capability, a first driving wheel, a first driven wheel mounted on an upper support frame, and a flexible traction member. The output end of the first motor is connected to the first driving wheel, and one end of the flexible traction member is connected to the first driving wheel, passes around the first driven wheel, and is connected to the sliding connecting rod. The lifting of the sliding connecting rod on the guide rail device is controlled by the bidirectional rotation of the first motor.

[0013] The material conveying mechanism includes a second motor, a drive shaft, and a P-group transmission system. Each group of transmission systems includes a second driving wheel, a third driven wheel located at the top of the upper inclined section, a fourth driven wheel located at the top of the lower inclined section, and a closed-loop transmission component that passes through the second driving wheel, the third driven wheel, and the fourth driven wheel in sequence. The output end of the second motor is connected to the drive shaft to drive the closed-loop transmission component to move upward. The drive shaft is located near the connection between the upper and lower inclined sections, and the second driving wheel is located on the drive shaft.

[0014] Several material distribution components are evenly distributed on the closed-loop transmission component;

[0015] The barrier fence is installed next to the closed-loop transmission component, and the lifting trajectory of the barrier fence is opposite to the running direction of the closed-loop transmission component in the downward inclined section.

[0016] It also includes an intelligent control system, including a controller and a material sensing module installed on the barrier fence; the controller receives the material accumulation signal detected by the sensing module, converts the signal into a digital signal and compares it with a preset threshold, and controls the start, stop, forward and reverse rotation and speed of the first motor according to the comparison result, while the controller simultaneously drives the start, stop and conveying speed of the second motor.

[0017] Further optimization involves the controller automatically triggering a three-level adjustment response based on the comparison results: under light load, it maintains a high-level barrier to form an initial buffer; under medium load, it drives the first motor to adjust the downward movement speed of the fence to control the material discharge rhythm; under heavy load, it drives the first motor to adjust the downward movement speed of the fence and simultaneously controls the second motor to reduce the conveying speed to avoid system overload.

[0018] Further optimization involves the controller using algorithms to optimize the coupling relationship between the speed of the first motor and the conveying speed of the second motor, ensuring that the lifting trajectory of the barrier fence always maintains a precise reverse match with the running direction of the closed-loop transmission components. Under the dual physical effects of gravity and motion vector difference, the crop bundle forms a pulse-like dispersion rhythm during the "contact-blockage-tear-release" process.

[0019] In a further optimized configuration, the output of the first motor is connected to the gearbox and then to the first drive wheel, while the output of the second motor is connected to the gearbox and then to the drive shaft.

[0020] In a further optimized configuration, the barrier fence is in its initial position when not bearing material, at which point the sliding connecting rod is located at the top of the track; when the barrier fence bears material, the sliding connecting rod can move down the track under the action of the sliding connecting rod lifting mechanism until it reaches the bottom of the track.

[0021] In a further optimized configuration, M barrier fences are set up one-to-one with P groups of flow guide frames, and the barrier fences are placed next to the closed-loop transmission components, with M = P ≥ 3.

[0022] Further optimizations include the placement of guide plates between adjacent guide frames, positioned outside the movement trajectories of the barrier fence and closed-loop transmission components.

[0023] In a further optimized version, the track is a slide bar, and the sliding element is a linear bearing or sliding sleeve that mates with the slide bar.

[0024] Further optimizations include using steel ropes or chains for flexible traction components and chains or synchronous belts for closed-loop transmission components.

[0025] In a further optimized version, the material distribution component is a material distribution rack. The top of the material distribution rack is provided with a guide bend that bends in the direction of material conveying, with a bending angle of approximately 30°-90°. The bottom of the material distribution rack is detachably connected to the closed-loop transmission component via a bolt assembly.

[0026] Furthermore, the sliding connecting rod lifting mechanism adopts a symmetrically distributed wheel set system, including:

[0027] Central transmission unit: The first driving wheel is located on the vertical central axis;

[0028] First-stage driven wheel assembly: Two first driven wheels are symmetrically distributed on both sides of the central axis of the first driving wheel and are installed inside the upper support frame;

[0029] Secondary driven wheel set: Two second driven wheels are symmetrically mounted on the lower support frame and are radially offset outward relative to the primary driven wheel set;

[0030] The third-stage driven wheel set: two fifth driven wheels are symmetrically installed on the outside of the upper support frame, and are further radially offset outward relative to the second-stage driven wheel set;

[0031] There are two flexible traction components, which are arranged along the transmission path from the center to the outside: each traction component is connected in sequence to the first driving wheel → the first driven wheel on the same side → the second driven wheel → the fifth driven wheel → the sliding connecting rod, forming a symmetrical traction network that extends from the central axis to both sides in a stepped manner.

[0032] Further optimizations include a P-group adjusting bracket; the adjusting bracket is composed of a hydraulic rod or a threaded rod, and also includes a P-group adjusting bracket; the adjusting bracket is a hydraulic rod or a threaded rod, one end of which is hinged to the lower inclined section and the other end is connected to the support frame through a rotating shaft; by driving the adjusting bracket to extend and retract, the tilt angle α of the lower inclined section can be adjusted to 30°-90°.

[0033] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0034] 1. This invention effectively solves the problem of poor processing results caused by crop accumulation at the inlet of existing crop processing equipment such as leaf peelers by the coordinated arrangement of multiple sets of support frames, guide frames, guide angles, tracks, sliding parts, sliding connecting rods, barrier fences, sliding connecting rod lifting mechanisms, and material conveying mechanisms. When unloaded, the barrier fence is in a high initial position; after being loaded, it can stably move downwards along a trajectory opposite to the material conveying direction (the running direction of the closed-loop transmission component at the downward inclined section) under the drive of the sliding connecting rod lifting mechanism, forming a reverse motion coordination.

[0035] When crops are placed on the high-level barrier fence by the conveying mechanism, the barrier fence forms the first barrier. The pressure generated by the accumulation of material forces the fence to move downwards. Under the combined action of the downward movement of the barrier fence and gravity, the crops move downwards. This downward movement is in the opposite direction to the material conveying direction, creating a strong "tearing" effect that effectively tears and disperses the originally tightly wrapped bundle of material. The crops then enter the distribution component of the closed-loop transmission in batches. Subsequently, driven by the distribution component, they move along the lower and upper inclined sections until they finally fall through the upper inclined section and enter the next process. This active and dynamic reverse dispersion method cannot be achieved by existing fixed fences or unidirectional movement devices, significantly improving dispersion.

[0036] Furthermore, the intelligent control system of this invention constructs a dynamic response closed-loop adjustment mechanism through the synergistic effect of the material sensing module and the controller. When the material distribution component on the closed-loop transmission component carries crops, the material sensing module at the barrier fence can monitor the accumulation amount in real time and convert it into a digital signal. The controller intelligently compares the real-time data with a preset threshold and activates the first and second motors in conjunction to begin dispersing and diverting the long-stemmed crops.

[0037] Compared with existing technologies, this invention achieves uniform dispersion and efficient transportation of crops through the coordinated operation of multiple sets of devices and a precise control mechanism, effectively solving the problem of crop accumulation in existing technologies and significantly improving the working efficiency of processing equipment such as leaf peelers and the quality of crop processing.

[0048] This invention provides an intelligent dispersing device for pretreatment of long-stemmed crops, comprising:

[0049] The support frame 1, as an overall load-bearing structure, includes at least a frame 11, and an upper support frame 12 and a lower support frame 13 mounted on the frame 11;

[0050] P groups of flow guide frames 2 are fixedly installed on the upper part of the support frame 1. Each group of flow guide frames 2 consists of an upper inclined section 21 and a lower inclined section 22 connected to each other. The upper inclined section 21 and the lower inclined section 22 form a flow guide angle of 110°-160°.

[0051] N sets of parallel guide rail devices 3, each set of guide rail devices 3 includes a rail and a sliding component; the rail is set on the support frame 1 and parallel to the downward inclined section 22, the length of the rail is less than or equal to the length of the downward inclined section 22, and N≥1;

[0052] Sliding connecting rod 4, which connects to N sliding parts of N sets of guide rail devices 3 respectively;

[0053] M barrier fences 6 are distributed and fixedly installed on the sliding connecting rod 4, M≥2;

[0054] The sliding connecting rod lifting mechanism includes a first motor 51 with bidirectional rotation capability, a first driving wheel 52, a first driven wheel 53 mounted on the upper support frame 12, and a flexible traction member 54. The output end of the first motor 51 is connected to the first driving wheel 52. One end of the flexible traction member 54 is connected to the first driving wheel 52, passes around the first driven wheel 53, and is connected to the sliding connecting rod 4. The bidirectional rotation of the first motor 51 controls the lifting of the sliding connecting rod 4 on the guide rail device 3.

[0055] The material conveying mechanism includes a second motor 71, a drive shaft 72, and a P-group transmission system. Each group of transmission systems includes a second driving wheel 73, a third driven wheel 74 located at the top of the upper inclined section 21, a fourth driven wheel 75 located at the top of the lower inclined section 22, and a closed-loop transmission component 76 that passes through the second driving wheel 73, the third driven wheel 74, and the fourth driven wheel 75 in sequence. The output end of the second motor 71 is connected to the drive shaft 72 to drive the closed-loop transmission component 76 to move upward. The drive shaft 72 is located near the connection between the upper inclined section 21 and the lower inclined section 22, and the second driving wheel 73 is located on the drive shaft 72.

[0056] Several material distribution components 8 are evenly distributed on the closed-loop transmission component 76;

[0057] The barrier fence 6 is positioned next to the closed-loop transmission component 76, and the lifting trajectory of the barrier fence 6 is opposite to the running direction of the closed-loop transmission component 76 in the lower inclined section 22.

[0058] It also includes an intelligent control system, including a controller and a material sensing module installed on the barrier fence 6; the controller receives the material accumulation signal detected by the sensing module, converts the signal into a digital signal and compares it with a preset threshold, and controls the start, stop, forward and reverse rotation and speed of the first motor 51 according to the comparison result, and the controller simultaneously drives the start, stop and conveying speed of the second motor 71.

[0059] In a further optimized configuration, the barrier fence 6 is in its initial position when it is not carrying any material, at which point the sliding connecting rod 4 is located at the top of the track. When the barrier fence 6 carries any material, the sliding connecting rod 4 can move down the track under the action of the sliding connecting rod lifting mechanism until it reaches the bottom of the track.

[0060] Reference Figure 4 In a further optimized embodiment, M = P = 4.

[0061] In this embodiment, the material sensing module is a photoelectric sensor, specifically an Omron E3X series photoelectric sensor, and the controller is a Siemens S7-200 series PLC. The material sensing module detects the material accumulation on the barrier fence 6, converts the detected analog signal into a digital signal, and compares it with a preset threshold. Based on the comparison result, the controller controls the start / stop, forward / reverse rotation, and speed of the first motor 51, while simultaneously controlling the start / stop and conveying speed of the second motor 71.

[0062] Similarly, the material sensing module in this embodiment can also use Honeywell's LC200 series load sensor, and the controller can be an Omron CP series PLC or a Raspberry Pi Pico microcontroller, etc.; the weight sensing module monitors the weight of the material on the barrier fence 6 in real time and converts the weight data into a digital signal; based on the comprehensive signal from the weight sensing module, the controller controls the start / stop, forward / reverse rotation and speed of the first motor 51, and at the same time controls the start / stop and conveying speed of the second motor 71.

[0063] Similarly, the material sensing module in this embodiment can be configured as both a photoelectric sensor and a weight sensing module. The material sensing module detects the material accumulation on the barrier fence 6, converts the detected analog signal into a digital signal, and compares it with a preset threshold. The weight sensing module monitors the weight of the material on the barrier fence 6 in real time and converts the weight data into a digital signal. Based on the combined signals from the material sensing module and the weight sensing module, the controller controls the start / stop, forward / reverse rotation, and speed of the first motor 51, while simultaneously controlling the start / stop and conveying speed of the second motor 71.

[0064] Working process and principle:

[0065] Crops enter the device through the feed inlet, landing on the upper inclined section of the guide frame and positioned on the barrier fence. The first motor starts, rotating in both directions to drive the first drive wheel, which in turn pulls the sliding connecting rod downwards along the track via a flexible traction component. Simultaneously, gravity causes the crops to slide downwards along the upper inclined section, propelled by the barrier fence. The downward movement of the sliding connecting rod gradually lowers the barrier fence, and the crops, guided by gravity and the barrier fence, fall in batches between the material distribution components of the closed-loop transmission mechanism below. The lifting trajectory of the barrier fence is opposite to the running direction of the closed-loop transmission mechanism in the lower inclined section. Upon entering the material distribution components, the crops move upwards under the drive of the closed-loop transmission mechanism. Reaching the end of the upper inclined section, gravity naturally closes the closed-loop transmission mechanism and the material distribution components, causing the crops to fall into the next process unit.

[0066] Throughout the process, the lifting trajectory of the barrier fence and the running direction of the closed-loop transmission components form a counter-movement coordination. This unique motion coordination effectively controls the flow and distribution of crops. Specifically, the movement speed of the barrier fence and the closed-loop transmission components, as well as the density and height settings of the material distribution components, can all adjust the amount of crops dispersed. The desired dispersion effect can be achieved by adjusting the parameters, avoiding excessive accumulation and blockage of materials, and ensuring that crops can enter the processing equipment evenly and stably.

[0067] Example 2

[0068] Based on Example 1, further optimization is made, with M barrier fences 6 and P groups of flow guiding frames 2 arranged in a one-to-one correspondence, and the barrier fences 6 are arranged next to the closed-loop transmission component 76.

[0069] It also includes a guide plate 9 disposed between adjacent guide frames 2, which is positioned outside the movement trajectory of the barrier fence 6 and the closed-loop transmission component 76. The optimized design of adding the guide plate not only improves the uniformity of crop dispersion but also avoids the accumulation and interference of materials in non-working areas, especially the interference of debris on the machine, ensuring smooth material flow and reliable operation of the device.

[0070] The track is a sliding rod, and the sliding element is a linear bearing or a sliding sleeve that mates with the sliding rod. This embodiment uses a sliding sleeve.

[0071] The flexible traction component 54 is a steel rope or chain; the closed-loop transmission component 76 is a chain or synchronous belt. In this embodiment, a steel rope is used, and the closed-loop transmission component 76 is a chain.

[0072] The material distribution component 8 is a material distribution rack. The top of the rack has a guide bend that curves in the direction of material conveying, with a bending angle of 30°-90°. The bottom of the rack is detachably connected to the closed-loop transmission component 76 via bolts. The guide bend of the rack effectively guides the flow of agricultural materials, reduces material accumulation and entanglement, and improves material distribution efficiency.

[0073] Example 3

[0074] Based on Example 1, the sliding connecting rod lifting mechanism is further optimized by adopting a symmetrically distributed wheel system, including:

[0075] Central transmission unit: The first drive wheel 52 is located on the vertical central axis;

[0076] First-stage driven wheel assembly: Two first driven wheels 53 are symmetrically distributed on both sides of the central axis of the first driving wheel 52 and are installed inside the upper support frame 12;

[0077] Secondary driven wheel set: Two second driven wheels 55 are symmetrically installed on the lower support frame 13, and are radially offset outward relative to the primary driven wheel set;

[0078] The third-stage driven wheel set: two fifth driven wheels 56 are symmetrically installed on the outside of the upper support frame 12, and are further radially offset outward relative to the second-stage driven wheel set;

[0079] There are two flexible traction components 54, which are arranged along the transmission path from the center to the outside: each traction component 54 is connected in sequence to the first driving wheel 52 → the first driven wheel 53 on the same side → the second driven wheel 55 → the fifth driven wheel 56 → the sliding connecting rod 4, forming a symmetrical traction network that extends from the central axis to both sides in a stepped manner.

[0080] This embodiment employs a symmetrically distributed wheel system, forming a unique multi-point support and transmission network. This significantly improves the stability of the sliding connecting rod's lifting motion, preventing swaying during operation. This allows the sliding connecting rod to maintain stable operation under complex conditions, adapting to the need for distributing heavier and larger crops, and enhancing the device's load-bearing capacity and applicability.

[0081] It also includes a P-group adjusting bracket 10; the adjusting bracket 10 is composed of a hydraulic rod or a threaded rod, and includes a P-group adjusting bracket 10; the adjusting bracket 10 is a hydraulic rod or a threaded rod, one end of which is hinged to the lower inclined section 22, and the other end is connected to the support frame 1 through a rotating shaft; by driving the adjusting bracket 10 to extend and retract, the tilt angle α of the lower inclined section 22 can be adjusted to 30°-90°. The tilt angle α is preferably 60°-75°. Through the flexible adjustment capability of the tilt angle of the lower inclined section, it can adapt to crops with different friction forces. Changing the tilt angle α can change the steepness of the lower inclined section, and the crop dispersion can be adjusted. Using a hydraulic rod or a threaded rod as the adjusting bracket, the structure is simple and the operation is convenient. It can quickly adapt to different crop types and processing requirements, expanding the application range of the device.
