[0002] In current agricultural production, a large amount of agricultural waste is generated, such as straw, rice husks, fruit husks, etc. However, the existing agricultural waste treatment technologies have many defects. On the one hand, the treatment efficiency and accuracy are generally not high. When multiple wastes are treated together, it is difficult to adjust the crushing process according to the different characteristics of the materials. For example, when hard straw and light rice husks are crushed, traditional equipment cannot be dynamically adjusted, resulting in increased energy consumption and uneven crushing effect, which affects subsequent resource utilization. On the other hand, the classification process mostly relies on a single dimension and only sorts according to the particle size, making it difficult to meet the actual needs of high-precision classification of multiple wastes, resulting in uneven quality of resource-based products. In addition, the functions of existing equipment are relatively single, and most can only achieve the functions of crushing or classification separately, with poor adaptability to different types of waste and unable to meet the diverse treatment needs of agricultural waste.

[0015] The technical solution of the present invention is further described below through the accompanying drawings and embodiments.

[0017] like Figure 1 As shown, an agricultural waste treatment system based on dynamic crushing and multi-dimensional classification coordination includes a frame 6, and a feeding module 1, a dynamic crushing module 2, a classification module 3, a coordinated control module 4 and a discharge module 5 are arranged on the upper surface of the frame 6; Feeding Module 1: Equipped with a multi-dimensional sensor array, including a laser ranging sensor, an infrared spectroscopy sensor, and a pressure sensor, it can collect physical and chemical properties of waste in real time, such as size, hardness, density, moisture content, and organic matter content. It adopts an intelligent flow control system, based on the PID control algorithm, to dynamically adjust the feeding speed according to the material properties, ensuring that the material flow entering the Dynamic Crushing Module 2 is evenly controllable. At the same time, a self-cleaning mechanism is set up to remove the adhered materials on the inner wall of the feeding channel by vibration or pneumatic means, preventing material blockage and adhesion, and ensuring the smoothness of the feeding process.

[0018] As Figure 2 shown, the Dynamic Crushing Module 2: The core is a double-layer blade structure. The upper layer is a spiral cutting blade 21 with adjustable angle, and the rotational speed range is 500 - 4000 rpm; the lower layer is a high-speed shearing blade 22, and the cutting angle adjustment range is 15° - 45°, and the gap adjustment range between the two blades is 0.5 - 5 mm. The blade material is selected as high-strength tungsten carbide alloy, which has self-sharpening performance and can effectively extend the service life. The control system adjusts the rotational speed, cutting angle, and gap of the double-layer blades in real time according to the data collected by the multi-dimensional sensor array, realizing the dynamic adaptive adjustment of the crushing parameters. For high-hardness materials (such as straw), the blade strength is automatically increased; for low-density materials (such as rice husk), the cutting force is reduced to save energy consumption.

[0019] As Figure 3 shown, the Classification Module 3: It includes a classification channel 31, and density sensors 32, humidity sensors 33, and an image recognition unit 34 are installed at the entrance, middle, and exit of the channel respectively. The image recognition unit 34 consists of a high-speed recognition camera 341. These sensors work together to realize the multi-dimensional detection and classification of material density, moisture content, and morphological characteristics. Below the classification channel 31, there is a variable cross-section air separation device optimized by computational fluid dynamics. According to the detection results of the sensors, it automatically realizes multi-channel separation through the air flow direction and intensity.

[0020] The Cooperative Control Module 4: Responsible for connecting the image recognition unit 34 with the Dynamic Crushing Module 2, and transmitting the information output by the image recognition unit 34 to the Dynamic Crushing Module 2. When the image recognition system determines that the particle size of a certain type of material is greater than the preset threshold, the Cooperative Control Module 4 will immediately issue an instruction, feedback to the Dynamic Crushing Module 2, automatically increase the rotational speed of the shearing blade 22 and the cutting blade 21, and adjust the gap and angle to enhance the crushing strength and uniformity, realizing the adaptive closed-loop adjustment of crushing and classification.

[0021] Discharging module 5: It includes a multi-channel intelligent shunting system to achieve automatic separation of different types of materials. An anti-blocking design combining screw conveyor and pneumatic conveyor is adopted, and the classification accuracy is verified online through weight sensors and image recognition systems to ensure that the classified materials are accurately conveyed to the corresponding channels. At the same time, it has a modular interface design, which is convenient for docking with subsequent processing equipment to realize the integrated process of agricultural waste treatment.

[0022] Working principle: Feeding stage: Agricultural waste first enters the feeding module 1, and multi-dimensional sensors continuously obtain the characteristics of the materials such as size, density, and moisture content. The intelligent flow control system adjusts the feeding flow rate according to the PID control algorithm to ensure that the materials enter the crushing system evenly and controllably. The self-cleaning mechanism is started regularly to prevent material blockage in the feeding channel.

[0023] Crushing stage: The waste enters the dynamic crushing module 2, and the upper spiral cutting knife 21 and the lower high-speed shearing knife 22 work together under the independent control of the frequency conversion system. According to the preset tasks or real-time feedback, the rotation speed of the upper blade is adjusted between 500 - 4000 rpm, the lower shearing angle varies within the range of 15° - 45°, and the gap is adjusted between 0.5 - 5 mm to achieve efficient coarse crushing and fine crushing of materials with different characteristics.

[0024] Classification stage: The crushed materials enter the classification module 3, and the density sensor 32, humidity sensor 33, and image recognition system respectively perceive the density, moisture content, and morphological characteristics of the materials in real time. The variable cross-section air separation device under the classification channel 31 automatically realizes multi-channel separation according to the judgment results of the sensors by adjusting the air flow direction and intensity.

[0025] Cooperative linkage: When the image recognition system detects that the particle size of a certain type of material is larger than the preset threshold, the cooperative control module 4 feeds back the instruction to the dynamic crushing module 2, automatically increasing the rotation speed of the shearing knife 22 and the cutting knife 21, and adjusting the gap and angle to enhance the crushing strength and uniformity. The intelligent control module continuously collects the operation data of each module, optimizes the equipment parameter configuration through the reinforcement learning algorithm, and records the operation history data to construct a knowledge graph, providing decision-making support for subsequent treatment of different types of materials.

[0026] Discharging stage: The classified materials enter the discharging module 5, and the multi-channel intelligent shunting system automatically separates the materials to the corresponding channels according to the classification results. The anti-blocking design combining screw conveyor and pneumatic conveyor ensures the smooth conveyance of materials, and the weight sensor and image recognition system verify the classification accuracy online. The modular interface of the discharging module 5 is convenient for docking with subsequent processing equipment to realize the resource utilization of agricultural waste.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify or equivalently replace the technical solutions of the present invention, and these modifications or equivalent replacements do not cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
