Description

Technical field

[0001] The present invention relates to the technical field of long-stem crop harvesting and processing, and in particular to an intelligent decentralized device for preprocessing long-stem crops. [Background Technology]

[0002] In agricultural industry chains such as sugarcane sugar production and comprehensive utilization of corn stalks, equipment such as defoliators and crushers are key processing links. However, the long-stalk crops such as sugarcane and corn stalks output by existing harvesting equipment are usually in a bundled state. When the crops (such as sugarcane and corn) harvested in batches are directly fed into the defoliator without effective dispersion, they often pile up and clog at the entrance, resulting in poor and incomplete defoliation. They may also damage the equipment, affecting production efficiency and processing quality. The current equipment has the following technical bottlenecks: material accumulation problems. When bundles of materials are concentrated into the entrance of the processing equipment, they are prone to material accumulation and blockage, resulting in incomplete processing (such as defoliation residue) or equipment overload and damage; low dispersion efficiency. The initial dispersion of crops by mechanical or pneumatic devices has limited dispersion effect and cannot meet the requirements of efficient operation of defoliators, affecting the quality of subsequent processing.

[0003] Therefore, developing a pretreatment dispersion device that can dynamically adapt to a variety of crops to improve the dispersion effect is of great significance to the improvement of the agricultural processing industry. [Summary of the invention]

[0004] The purpose of the present invention is to provide an intelligent dispersion device for pre-processing long-stem crops to address the problem that crops such as sugarcane enter in piles at the entrance of existing crop processing equipment, resulting in poor processing results. By dispersing the piled crops and sending them into the processing equipment, the processing results and production efficiency of subsequent processes can be improved.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] An intelligent dispersion device for pre-processing long-stem crops, comprising:

[0007] The supporting frame, as an integral bearing structure, comprises at least a frame, and an upper supporting frame and a lower supporting frame mounted on the frame;

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

[0009] N sets of parallel guide rail devices, each set of guide rail devices including rails and sliding members; the rails are arranged on the support frame and are parallel to the lower inclined section, the length of the rails is less than or equal to the length of the lower inclined section, and N ≥ 1;

[0010] Sliding connecting rods, the sliding connecting rods respectively connecting N sliding members of the N groups of guide rail devices;

[0011] M barrier fences, which are fixedly arranged on the sliding connecting rods in a dispersed manner, M ≥ 2;

[0012] The sliding connecting rod lifting mechanism includes a first motor capable of forward and reverse bidirectional rotation, 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 forward and reverse bidirectional rotation of the first motor controls the lifting and lowering of the sliding connecting rod on the guide rail device.

[0013] The material conveying mechanism includes a second motor, a transmission shaft, and P groups of transmission systems. Each transmission system includes a second driving wheel, a third driven wheel disposed at the top of the upper inclined section, a fourth driven wheel disposed at the top of the lower inclined section, and a closed-loop transmission member sequentially spanning the second driving wheel, the third driven wheel, and the fourth driven wheel. The output end of the second motor is connected to the transmission shaft to drive the closed-loop transmission member upward. The transmission shaft is disposed near the junction of the upper inclined section and the lower inclined section, and the second driving wheel is disposed on the transmission shaft.

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

[0015] The barrier fence is arranged beside the closed-loop transmission member, and the lifting track of the barrier fence is matched in the opposite direction to the running direction of the closed-loop transmission member in the lower 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 detection signal from the sensing module, and converts the signal into a digital signal and compares it with a preset threshold. According to the comparison result, the controller controls the start and stop, forward and reverse rotation, and speed of the first motor, and the controller simultaneously drives the start and stop and conveying speed of the second motor.

[0017] Further optimized, the controller automatically triggers a three-level adjustment response based on the comparison results: maintains a high-level barrier to form a preliminary buffer when lightly loaded, drives the first motor to adjust the downward speed of the fence to control the rhythm of material discharge when medium loaded, and drives the first motor to adjust the downward speed of the fence when heavily loaded, and simultaneously controls the second motor to reduce the conveying speed to avoid system overload.

[0018] Furthermore, the controller uses an algorithm to optimize the coupling relationship between the first motor's speed and the second motor's conveying speed, ensuring that the barrier's lifting trajectory always maintains precise inverse coordination with the closed-loop transmission's operating direction. Under the dual physical effects of gravity and motion vector difference, the crop bundle forms a pulsed, dispersed rhythm during the "contact-blockage-tear-release" process.

[0019] Further optimized, the output end of the first motor is connected to the transmission and then to the first driving wheel, and the output end of the second motor is connected to the transmission and then to the drive shaft.

[0020] Further optimized, the barrier fence is in the initial position when it is not bearing material, and the sliding connecting rod is at the top of the track; when the barrier fence is bearing material, the sliding connecting rod can move down along the track under the action of the sliding connecting rod lifting mechanism until it reaches the bottom of the track.

[0021] For further optimization, M barrier fences are arranged in one-to-one correspondence with P groups of guide frames, the barrier fences are arranged next to the closed-loop transmission parts, and M=P≥3.

[0022] Further optimization also includes guide plates arranged between adjacent guide frames, and the guide plates are arranged at positions outside the movement trajectory of the blocking fence and the closed-loop transmission member.

[0023] Further optimized, the track is a slide rod, and the sliding member is a linear bearing or a sliding sleeve that cooperates with the slide rod.

[0024] Further optimized, the flexible traction member is a steel rope or a chain; the closed-loop transmission member is a chain or a synchronous belt.

[0025] Further optimized, the material dividing component is a material dividing rack, and the top of the material dividing rack is provided with a guide bending portion bent in the material conveying direction, and the bending angle of the guide bending portion is about 30°-90°; the bottom of the material dividing rack is detachably connected to the closed-loop transmission member through a bolt group.

[0026] The further optimized sliding connecting rod lifting mechanism adopts a symmetrically distributed wheel system, including:

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

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

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

[0030] Three-stage driven wheel assembly: two fifth driven wheels are symmetrically mounted on the outside of the upper support frame, further radially outwardly offset relative to the two-stage driven wheel assembly;

[0031] There are two flexible traction members, which are arranged along the transmission path from the center to the outside: each traction member 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 expands in a step-by-step manner from the central axis to both sides.

[0032] Further optimization also includes a P group adjustment bracket; the adjustment bracket is composed of a hydraulic rod or a threaded rod, and also includes a P group adjustment bracket; the adjustment 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 adjustment bracket to extend and retract, the inclination angle α of the lower inclined section is 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 addresses the problem of crop accumulation at the inlet of existing crop processing equipment, such as defoliators, resulting in poor processing results, by synergizing multiple support frames, a diversion frame, diversion angles, tracks, slides, sliding connecting rods, barrier fences, a sliding connecting rod lifting mechanism, and a material conveying mechanism. When unloaded, the barrier fences are in a high, initial position. When loaded, they are driven by the sliding connecting rod lifting mechanism to stably move downward in a direction opposite to the material conveying direction (the direction of operation of the closed-loop transmission element at the lower inclined section), creating a counter-rotating motion.

[0035] When mature crops are placed on the high barrier fence by the conveying mechanism, it forms the first barrier. The pressure generated by the accumulated material forces the fence downward. Under the dual effects of the downward movement of the barrier fence and gravity, the crops move downward in the opposite direction of the material conveying, creating a powerful "tearing" effect, effectively tearing and dispersing the originally tightly entangled material bundles. The crops are then gradually transferred into the distributing component of the closed-loop transmission. Driven by the distributing component, they move along the downward and upward inclined sections until they pass through the upward section and finally fall to the next process. This active, dynamic reverse dispersion method is impossible to achieve with existing fixed fences or co-directional motion devices, significantly improving dispersion.

[0036] Furthermore, the intelligent control system of this invention utilizes the synergistic effect of the material sensing module and the controller to establish a dynamic, closed-loop regulation mechanism. When the material distribution component of the closed-loop transmission is loaded with crops, the material sensing module at the barrier fence monitors the accumulation in real time and converts it into a digital signal. The controller intelligently compares this real-time data with a preset threshold and activates the first and second motors in a coordinated manner, beginning to disperse and divert the long-stemmed crops.

[0037] Compared with the existing technology, the present invention achieves uniform dispersion and efficient transportation of crops through the coordinated operation of multiple groups of devices and precise control mechanism, effectively solves the problem of crop accumulation in the existing technology, and significantly improves the working efficiency of processing equipment such as leaf strippers and the quality of crop processing.

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 then connects to the sliding connecting rod 4. The forward and reverse bidirectional rotation of the first motor 51 controls the lifting and lowering of the sliding connecting rod 4 on the guide rail device 3.

[0055] The material conveying mechanism includes a second motor 71, a transmission shaft 72, and P groups of transmission systems. Each transmission system includes a second driving wheel 73, a third driven wheel 74 disposed at the top of the upper inclined section 21, a fourth driven wheel 75 disposed at the top of the lower inclined section 22, and a closed-loop transmission member 76 that sequentially spans the second driving wheel 73, the third driven wheel 74, and the fourth driven wheel 75. The output end of the second motor 71 is connected to the transmission shaft 72 to drive the closed-loop transmission member 76 to move upward. The transmission shaft 72 is disposed near the junction of the upper inclined section 21 and the lower inclined section 22, and the second driving wheel 73 is disposed on the transmission shaft 72.

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

[0057] The blocking fence 6 is arranged beside the closed-loop transmission member 76, and the lifting trajectory of the blocking fence 6 is matched in the opposite direction to the running direction of the closed-loop transmission member 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 blocking fence 6; the controller receives the material accumulation detection signal from the sensing module, and converts the signal into a digital signal and compares it with a preset threshold value. According to the comparison result, the controller controls the start and stop, forward and reverse rotation, and speed of the first motor 51, and the controller simultaneously drives the start and stop and conveying speed of the second motor 71.

[0059] Further optimized, the blocking fence 6 is in the initial position when it is not bearing material, and the sliding connecting rod 4 is at the top of the track; when the blocking fence 6 is bearing material, the sliding connecting rod 4 can move down along the track under the action of the sliding connecting rod lifting mechanism until it reaches the bottom end of the track.

[0060] Reference Figure 4 , further optimized, in this embodiment, M=P=4,

[0061] In this embodiment, the material sensing module is a photoelectric sensor, using the Omron E3X series photoelectric sensor, and the controller uses the 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 and stop, forward and reverse rotation and speed of the first motor 51, and at the same time controls the start and stop and conveying speed of the second motor 71.

[0062] Similarly, the material sensing module in this embodiment can also adopt 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; according to the comprehensive signal of the weight sensing module, the controller controls the start and stop, forward and reverse rotation and speed of the first motor 51, and at the same time controls the start and stop and conveying speed of the second motor 71.

[0063] Similarly, the material sensing module in this embodiment can be set as a photoelectric sensor and a weight sensing module at the same time. The material sensing module detects the accumulation of materials on the blocking 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 blocking fence 6 in real time, and converts the weight data into a digital signal; according to the comprehensive signal of the material sensing module and the weight sensing module, the controller controls the start and stop, forward and reverse rotation and speed of the first motor 51, and controls the start and stop and conveying speed of the second motor 71 at the same time.

[0064] Working process and principle:

[0065] The crops enter the device through the feed port, fall on the upper inclined section of the guide frame and are located on the barrier fence. The first motor starts, and drives the first driving wheel to rotate through forward and reverse bidirectional rotation, and then pulls the sliding connecting rod to move downward along the track through the flexible traction member; at the same time, under the action of gravity, the barrier fence drives the crops to slide downward along the upper inclined section. The downward movement of the sliding connecting rod causes the barrier fence to gradually lower, and the crops, guided by gravity and the barrier fence, fall in batches between the distributing parts of the closed-loop transmission member below. The lifting trajectory of the barrier fence is opposite to the running direction of the closed-loop transmission member in the lower inclined section. When the crops enter between the distributing parts, they move upward under the drive of the closed-loop transmission member. After reaching the end of the upper inclined section, they naturally fall into the equipment of the next process under the action of gravity, which is naturally caused by the closed-loop transmission member and the distributing member.

[0066] Throughout the entire process, the lifting and lowering trajectory of the barrier fence and the operating direction of the closed-loop transmission form a counter-motion coordination. This unique motion coordination relationship effectively controls the flow and distribution of crops. Specifically, the movement speed of the barrier fence and the closed-loop transmission, the density and height setting of the material distribution components can all adjust the dispersion amount of crops. The parameters can be adjusted to achieve the desired dispersion effect, 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 further optimization of Example 1, M barrier fences 6 are arranged in a one-to-one correspondence with P groups of guide frames 2, and the barrier fences 6 are arranged next to the closed-loop transmission member 76.

[0069] The system also includes guide plates 9 disposed between adjacent guide frames 2, positioned outside the motion paths of the barrier fence 6 and the closed-loop transmission member 76. The optimized design of the guide plates not only improves the uniformity of crop dispersion but also prevents accumulation and interference of materials in non-working areas, particularly from leaves, thereby ensuring smooth material flow and reliable operation.

[0070] The track is a slide bar, and the sliding member is a linear bearing or a sliding sleeve that cooperates with the slide bar. What this embodiment adopts is a sliding sleeve.

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

[0072] The material distribution component 8 is a distribution rack. The top of the distribution rack is equipped with a diversion bend that bends in the direction of material delivery at an angle of 30°-90°. The bottom of the distribution rack is detachably connected to the closed-loop transmission member 76 via a bolt assembly. The diversion bend of the distribution rack effectively guides the flow of crops, reduces material accumulation and entanglement, and improves distribution efficiency.

[0073] Example 3

[0074] Based on the further optimization of Example 1, the sliding connecting rod lifting mechanism adopts a symmetrically distributed wheel system, including:

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

[0076] Primary 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 installed on the inner side of the upper support frame 12;

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

[0078] Three-stage driven wheel assembly: two fifth driven wheels 56 are symmetrically mounted on the outside of the upper support frame 12, further radially outwardly offset relative to the two-stage driven wheel assembly;

[0079] There are two flexible traction members 54, which are arranged along the transmission path from the center to the outside: each traction member 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 expands in a step-by-step manner from the central axis to both sides.

[0080] This embodiment adopts a symmetrically distributed wheel system to form a unique multi-point support and transmission network, which significantly improves the stability of the sliding connecting rod's lifting movement and prevents shaking during operation. This allows the sliding connecting rod to maintain a stable operating state under complex working conditions, adapting to the needs of dispersing crops of larger weight and size, and improving the device's carrying capacity and scope of application.

[0081] It also includes a P group adjustment bracket 10; the adjustment bracket 10 is composed of a hydraulic rod or a threaded rod, and also includes a P group adjustment bracket 10; the adjustment 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 adjustment bracket 10 to extend and retract, the inclination angle α of the lower inclined section 22 is adjusted to 30°-90°. The inclination angle α is more preferably 60°-75°. By flexibly adjusting the inclination angle of the lower inclined section, it can adapt to crops with different friction forces. Changing the inclination angle α can change the steepness of the lower inclined section and adjust the amount of crop dispersion. Using a hydraulic rod or a threaded rod as an adjustment bracket has a simple structure and is easy to operate. It can quickly adapt to different crop types and processing requirements, expanding the application range of the device.
