TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural machinery, in particular to an intelligent flexible bundling device for self-adapting to branch and leaf of bigleaf fig. BACKGROUND

[0002] As an important raw material of traditional Chinese medicine, the branch and leaf of bigleaf fig (Radix Isatidis) has significant technical difficulties in harvesting and bundling. Firstly, the branch and leaf has high water content and strong fiber toughness, and the conventional rigid compression device is easy to cause juice loss and leaf damage, reducing the quality of medicinal materials. Secondly, the branch and leaf is fluffy and irregular in shape, and the existing fixed-size bundling channel is easy to cause entanglement and blockage. Thirdly, the traditional bundling method uses fixed force, which is easy to cause mold of the branch and leaf due to over-tight bundling or scattering of the bundle due to over-loose bundling. In the prior art, although some crop bundling machines have compression function, they lack adaptation to the characteristics of the branch and leaf of bigleaf fig (Radix Isatidis), and it is difficult to achieve efficient and high-quality bundling operation, so it is urgent to develop a special bundling device with innovation and practicality. Therefore, we propose an intelligent flexible bundling device for self-adapting to branch and leaf of bigleaf fig. SUMMARY

[0003] In order to overcome the shortcomings of the prior art, the present application provides an intelligent flexible bundling device for self-adapting to branch and leaf of bigleaf fig, which is provided with a double-layer corrugated flexible conveying structure, so that the air bag and the flexible restraint curtain work together to realize zero-damage conveying of the branch and leaf, and the complete rate of medicinal materials is improved by 40%. The variable cross-section compression cavity and the gradient compression technology break through the fixed size compression mode, effectively solve the problem of blockage, and the compression efficiency is improved by 35%. The shape memory alloy bundling belt is combined with intelligent tension control to realize precise self-adaptation of the bundling force, reduce the risk of mold of the branch and leaf, and greatly improve the qualified rate of bundling.

[0004] To address the aforementioned technical problems, this invention provides the following technical solution: an intelligent flexible bundling device for adaptive Isatis tinctoria branches and leaves, comprising an intelligent compressor body, which includes a flexible conveying module, an intelligent compression module, an intelligent control system, and a flexible bundling module. The flexible conveying module has a double-layer corrugated conveyor belt and a flexible constraint curtain. The intelligent compression module includes a variable cross-section compression chamber and a gradient compression system. The flexible bundling module uses shape memory alloy bundling tape and intelligent tension control. The intelligent control system uses an integrated AI image recognition and fuzzy control algorithm. A pressure sensor array is distributed and installed inside the intelligent control system. The upper layer of the double-layer corrugated conveyor belt is made of elastic silicone material, and the surface of the double-layer corrugated conveyor belt is densely covered with micro-convex airbags. The lower layer of the double-layer corrugated conveyor belt is a high-strength fiber belt. Flexible constraint curtains are set on both sides of the double-layer corrugated conveyor belt. The flexible constraint curtains are woven from shape memory alloy wires and elastic fibers. A transmission mechanism is set on one side of the double-layer corrugated conveyor belt, and a servo motor is installed on one side of the transmission mechanism. The servo motor automatically adjusts the conveying speed by monitoring the conveying resistance in real time through pressure sensors.

[0005] As a preferred embodiment of the present invention, an ultrasonic humidifier is configured on the top of the compression chamber of the intelligent compressor body. The compression chamber of the intelligent compressor body has a variable cross-section structure. A compression plate is installed inside the compression chamber of the intelligent compressor body. An electric push rod is installed on one side of the compression plate. The surface of the compression plate is covered with a memory foam layer. A pressure distribution sensor array is embedded inside the compression plate. A hydraulic system is provided at one end of the electric push rod.

[0006] As a preferred embodiment of the present invention, the flexible binding module uses shape memory alloy binding tape to achieve adaptive adjustment of binding force through fiber optic sensors and fuzzy control algorithms. The initial state of the shape memory alloy binding tape is a flat ring. The binding mechanism of the flexible binding module includes a tension sensing device. The tension sensing device detects the tensile stress of the binding tape through fiber optic sensors and combines the volume and density data of branches and leaves with the fuzzy control algorithm to adjust the binding force in real time.

[0007] As a preferred embodiment of the present invention, the flexible strapping module is provided with a cutting device on one side of the strapping mechanism, and the cutting device is a laser cutting machine.

[0008] As a preferred technical solution of the present invention, the intelligent control system includes a binocular camera, an edge computing unit, and a cloud data interaction module. The integrated AI image recognition module of the intelligent control system collects branch and leaf morphology and density information through the binocular camera. After the edge computing unit analyzes the data in real time, it calls the pre-stored characteristic model of Daqingye (Isatis tinctoria) to automatically optimize the conveying speed, compression parameters, and binding force. The intelligent control system supports cloud data interaction and can remotely monitor the equipment operation status through a mobile terminal.

[0009] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0010] 1. The double-layer corrugated flexible conveying structure enables the airbags and flexible restraint curtains to work together to achieve zero-damage conveying of branches and leaves, increasing the integrity rate of medicinal materials by 40%.

The flexible conveying module 2 has a double-layer corrugated conveyor belt 7 and a flexible constraint curtain 10.

The lower layer of the double-layer corrugated conveyor belt 7 is a high-strength fiber belt 6. The double-layer corrugated conveyor belt 7 is equipped with flexible restraint curtains 10 on both sides. The flexible restraint curtains 10 are woven from shape memory alloy wires and elastic fibers. A transmission mechanism 9 is set on one side of the double-layer corrugated conveyor belt 7, and a servo motor 8 is installed on the other side of the transmission mechanism 9. The servo motor 8 automatically adjusts the conveying speed by monitoring the conveying resistance in real time through a pressure sensor. Through the double-layer corrugated flexible conveying structure, the airbag and the flexible restraint curtain work together to achieve zero-damage conveying of branches and leaves, increasing the integrity rate of medicinal materials by 40%. The variable cross-section compression chamber and gradient compression technology break through the fixed size compression mode, effectively solving the blockage problem and increasing the compression efficiency by 35%. The shape memory alloy binding straps combined with intelligent tension control achieve precise adaptive binding force, reduce the risk of mold growth on branches and leaves, and greatly improve the binding qualification rate.

[0019] like Figure 1 , Figure 3 As shown, an ultrasonic humidifier 15 is configured on the top of the compression chamber of the intelligent compressor body 1. The compression chamber of the intelligent compressor body 1 has a variable cross-section structure. A compression plate 14 is installed inside the compression chamber of the intelligent compressor body 1. An electric push rod 13 is installed on one side of the compression plate 14. The surface of the compression plate 14 is covered with a memory foam layer. A pressure distribution sensor array is embedded inside the compression plate 14.

[0020] like Figure 1 , Figure 4As shown, the flexible binding module 5 uses shape memory alloy binding tape to achieve adaptive adjustment of binding force through fiber optic sensors and fuzzy control algorithms. The initial state of the shape memory alloy binding tape is a flat ring. The binding mechanism of the flexible binding module 5 includes a tension sensing device. The tension sensing device detects the tensile stress of the binding tape through fiber optic sensors and combines the volume and density data of branches and leaves to adjust the binding force in real time based on the fuzzy control algorithm.

[0021] like Figure 4 As shown, the flexible strapping module 5 has a cutting device on one side of its strapping mechanism. The cutting device is a laser cutter. By setting the cutting device to a laser cutter, the cross-section of the strapping tape is heated instantly after laser cutting to prevent loosening.

It supports rapid switching between multiple scenarios, and its modular design facilitates disassembly and cleaning, meeting the hygiene standards for the production of Chinese medicinal materials.

[0023] Specific device operation procedure:

[0024] Branch and leaf conveying stage: After harvesting, the branches and leaves of Daqingye are laid flat on the double-layer corrugated conveyor belt 7. After the pressure sensor detects the weight of the branches and leaves, the servo motor 8 starts. When the resistance of the conveyor belt exceeds the threshold, the intelligent control system 4 automatically reduces the speed of the servo motor 8, and at the same time, the micro-convex airbags 11 inflate to enhance the flexible clamping of the branches and leaves and prevent slippage.

[0025] Intelligent compression stage: After the branches and leaves enter the compression chamber, the binocular camera 12 identifies the accumulation pattern of the branches and leaves, and the electric push rod 13 adjusts the width of the compression chamber according to the algorithm. In the pre-compression stage, the hydraulic system pushes the compression plate 14 with a pressure of 0.2MPa for 10 seconds to expel air. Subsequently, the pressure distribution sensor detects the pressure on the branches and leaves. If the local pressure exceeds 0.5MPa, which is the critical value for sap extrusion, the hydraulic system automatically reduces the pressure until the pressure is evenly distributed. The ultrasonic humidifier 15 works simultaneously to maintain the surface humidity of the branches and leaves at 65%-75%, improving the compression effect.

[0026] Flexible binding stage: The compressed and shaped branch and leaf block triggers the fiber optic sensor, the shape memory alloy binding tape automatically fits in, the tension sensing device monitors the binding stress in real time, and when the stress reaches the preset range, the laser cutting machine starts and simultaneously heats the cross-section at 200°C to complete the binding.

[0027] Data interaction and optimization: After every 10 bundles are completed, the intelligent control system 4 uploads the operating data, such as compression pressure, bundling force, and conveying speed, to the cloud. The parameter model is optimized through machine learning algorithms to improve the efficiency of subsequent operations.
