Description

Technical Field

[0001] This invention application relates to the field of crushing and processing technology, specifically to a crushing and processing equipment for recycling agricultural product processing by-products, and also to a method for processing agricultural product processing by-products. Background Technology

[0002] In the field of agricultural product processing, stalk-shaped agricultural product processing by-products such as corn stalks, sugarcane bagasse, hemp stalks, and cotton stalks are common biomass resources. Their recycling and reuse can realize the secondary development of resources and are widely used in many fields such as biomass fuel, feed processing, and papermaking raw materials. This is of great significance for increasing the added value of agricultural product processing and promoting the development of a circular agricultural economy. The crushing treatment of stalk-shaped agricultural product processing by-products is a core preliminary step for their recycling and reuse. The crushing effect directly affects the efficiency of subsequent processing and the quality of the finished product. Therefore, it is necessary to process them into fine particles using specialized crushing equipment to meet the requirements of subsequent industrial processing.

[0003] Currently, most crushing equipment for rod-shaped agricultural product processing by-products is a single shearing or hammer mill structure, which directly cuts and crushes the rod-shaped material using only one or more stages of blades. This type of equipment first coarsely shears the rod-shaped material into small, near-cylindrical segments, which are then directly fed into the fine crushing unit for further shearing. However, these near-cylindrical segments have a limited contact area with the fine crushing blades, resulting in a high shearing load on the fine crushing unit, rapid blade wear, and a short service life. Summary of the Invention

[0004] To address the aforementioned issues, a crushing and processing equipment for recycling agricultural product processing by-products is provided. Through a vertical, layered layout and the coordinated operation of a coarse crushing unit, an axial separating unit, and a fine crushing unit, the equipment achieves the splitting of cylindrical segments along an axially symmetrical plane, thereby reducing the shear load on the fine crushing unit.

[0005] To address the problems of existing technologies, this invention provides a crushing and processing equipment for recycling agricultural product processing by-products, comprising a coarse crushing unit, an axial separating unit, and a fine crushing unit arranged sequentially from top to bottom. The coarse crushing unit is used to cut rod-shaped by-products into small, cylindrical segments. The axial separating unit is located between the coarse crushing unit and the fine crushing unit. The axial separating unit includes a frame, a guide separating tooth assembly in the middle of the frame, and two sets of symmetrically arranged adaptive clamping separating components. The two sets of adaptive clamping separating components can elastically and adaptively adjust their spacing in the horizontal direction to accommodate small, cylindrical segments of different diameters, and simultaneously apply a downward clamping and conveying force to the small, cylindrical segments, cooperating with the guide separating tooth assembly to separate the small, cylindrical segments into two halves along their axial symmetry plane. The fine crushing unit is used to finely crush the separated semi-cylindrical materials.

[0006] Preferably, the guide gear assembly includes a plurality of equally spaced gear teeth, and an upward-facing V-shaped opening is formed between adjacent gear teeth.

[0007] Preferably, the adaptive clamping and dispensing assembly includes a clamping and conveying assembly and an elastic abutment assembly; the clamping and conveying assembly is used to apply a downward clamping and conveying force to the cylindrical segment; the elastic abutment assembly is used to push the clamping and conveying assembly to press against the cylindrical segment in the middle of the frame.

[0008] Preferably, the clamping and conveying assembly includes an annular clamping belt, the conveying surface of which is parallel to the guide tooth assembly, and the conveying surface of which extends from the upper end of the guide tooth assembly to the lower end of the guide tooth assembly.

[0009] Preferably, the conveying surface of the annular clamping belt is provided with multiple anti-slip teeth at equal intervals to enhance the downward clamping and conveying force on the cylindrical segments.

[0010] Preferably, the elastic abutment assembly includes a guide rod and a spring; the guide rod is slidably connected to the frame, and one end of it is connected to the clamping and conveying assembly; the spring is used to provide a thrust to the clamping and conveying assembly toward the middle of the frame.

[0011] Preferably, the axial sorting unit further includes a feed hopper, the upper inlet of which is connected to the coarse crushing unit, and the lower outlet of which is located between the two adaptive clamping and sorting components.

[0012] Preferably, the coarse crushing unit includes two sets of coarse shearing rollers rotating in opposite directions, used to cut the rod-shaped by-products into cylindrical segments.

[0013] Preferably, the fine grinding unit includes two sets of fine grinding blades rotating in opposite directions, used for shearing and grinding semi-cylindrical materials.

[0014] A method for processing agricultural by-products, applied to a crushing and processing equipment for recycling agricultural by-products, includes the following steps: S1. The rod-shaped agricultural product processing by-product is fed into the coarse crushing unit, which cuts the rod-shaped agricultural product processing by-product into cylindrical segments. S2. The cylindrical segment falls between the two adaptive clamping and distributing components under the action of gravity, and the guide distributing teeth form a contact limit on the cylindrical segment. S3. The two adaptive clamping and distributing components simultaneously apply a downward clamping and conveying force to the cylindrical segment. This force forms a reverse force with the abutting force of the guide distributing tooth group. The two work together to divide the cylindrical segment into two halves along the axial symmetry plane. S4. The semi-cylindrical material, divided into two halves, falls into the fine grinding unit, where it undergoes fine grinding.

[0015] The advantages of this invention application compared to the prior art are: 1. This invention application sets up a coarse crushing unit, an axial separating unit, and a fine crushing unit. The coarse crushing unit first shears the rod-shaped by-product into small cylindrical segments. The material falls under gravity into the axial separating unit between the coarse and fine crushing units. The guide separating tooth assembly limits the material and provides a resisting force. The adaptive clamping separating components on both sides adaptively adapt to the small cylindrical segments of different diameters and apply a downward clamping and conveying force to the small cylindrical segments. This force forms a counterforce with the resisting force of the guide separating tooth assembly, and together they separate the material into semi-cylindrical shapes along the axial symmetry plane. Finally, the fine crushing unit completes fine shearing and crushing of the semi-cylindrical material. Through the vertical layered layout and the coordinated work of the coarse crushing unit, the axial separating unit, and the fine crushing unit, an axial separating unit is introduced between the coarse and fine crushing units. By using the frame positioning guide separating tooth assembly and the adaptive clamping separating components, through the synergistic effect of adaptive spacing adjustment and synchronous clamping and conveying, the splitting of the small cylindrical segments along the axial symmetry plane is achieved, reducing the shearing load of the fine crushing unit.

[0016] 2. This invention application sets up multiple equally spaced separating teeth, and forms an upward-facing V-shaped opening between adjacent separating teeth. The cylindrical segments cut by the coarse crushing unit fall into the V-shaped opening of the guide separating tooth assembly. The inclined inner wall of the opening guides and limits the material. The inclined edge of the separating teeth expands its effective utilization range. The adaptive clamping and separating component applies a downward clamping and conveying force, which works in conjunction with the inclined cutting edge of the separating teeth and the limiting force of the V-shaped opening to separate the material into two halves along the axial symmetry plane. Through the design of multiple equally spaced separating teeth and upward-facing V-shaped openings, the effective working range is expanded by the inclined edge of the separating teeth, thereby enabling a larger cutting edge on the separating teeth to participate in the separating and improving the separating efficiency.

[0017] 3. This invention application provides a clamping and conveying component and an elastic abutment component. The adaptive clamping and dispensing component achieves adaptive adaptation to small cylindrical segments of different diameters by functionally separating and coordinating the clamping and conveying component and the elastic abutment component, and by utilizing the elastic thrust of the elastic abutment component.

[0030] To further understand the features, technical means, and specific objectives and functions achieved by this invention application, the invention application will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figures 1 to 11 The image shows a crushing and processing equipment for recycling by-products from agricultural product processing, comprising a coarse crushing unit 1, an axial separating unit 2, and a fine crushing unit 3 arranged sequentially from top to bottom. The coarse crushing unit 1 is used to cut rod-shaped by-products into small cylindrical segments. The axial separating unit 2 is located between the coarse crushing unit 1 and the fine crushing unit 3. The axial separating unit 2 includes a frame 21, a guide separating tooth group 22 in the middle of the frame 21, and two sets of symmetrically arranged adaptive clamping separating components 23. The two sets of adaptive clamping separating components 23 can elastically and adaptively adjust their spacing in the horizontal direction to accommodate small cylindrical segments of different diameters, and simultaneously apply a downward clamping and conveying force to the small cylindrical segments, cooperating with the guide separating tooth group 22 to separate the small cylindrical segments into two halves along their axial symmetry plane. The fine crushing unit 3 is used to finely crush the separated semi-cylindrical materials.

[0032] First, the rod-shaped agricultural product processing by-products are fed into the coarse crushing unit 1. After the coarse crushing unit 1 starts, it shears and cuts the rod-shaped by-products into small cylindrical segments. Subsequently, under their own gravity, the small cylindrical segments fall from the discharge end of the coarse crushing unit 1 and enter the axial distribution unit 2 located between the coarse crushing unit 1 and the fine crushing unit 3. When the small cylindrical segments reach the axial distribution unit 2, the guide distribution tooth assembly 22 in the middle of the frame 21 first limits their downward movement; at the same time, the adaptive clamping distribution components 23 on both sides elastically and adaptively adjust the spacing in the horizontal direction according to the actual diameter of the small cylindrical segments, so as to adapt to small cylindrical segments of different diameters and avoid material slippage due to excessive spacing or material compression due to insufficient spacing. After adaptation, the two sets of adaptive clamping and separating components 23 simultaneously apply a downward clamping and conveying force to the semi-cylindrical segment. This clamping and conveying force and the abutting force of the guide separating tooth assembly 22 on the semi-cylindrical segment form a counterforce. The two work together to separate the semi-cylindrical segment into two halves along its axial symmetry plane, forming uniform semi-cylindrical materials. Finally, the separated semi-cylindrical materials fall from the axial separating unit 2 to the lowest fine crushing unit 3 under the action of gravity. After the fine crushing unit 3 is activated, it performs fine shearing and crushing on the semi-cylindrical materials, ultimately completing the full crushing treatment of the rod-shaped agricultural product processing by-product. Through the vertical layered layout and the coordinated work of the coarse crushing unit 1, the axial splitting unit 2, and the fine crushing unit 3, the axial splitting unit 2 is introduced between the coarse crushing and fine crushing units 3. The frame 21 is used to position and guide the splitting tooth group 22 and the adaptive clamping splitting component 23. Through the coordinated action of adaptive spacing adjustment and synchronous clamping and conveying, the quasi-cylindrical small segments are split along the axial symmetry plane, which reduces the shear load of the fine crushing unit 3.

[0033] Reference Figure 3 , Figure 4 and Figure 5As shown: The guide gear assembly 22 includes a plurality of gear teeth 221 arranged at equal intervals, and an upward-facing V-shaped opening is formed between adjacent gear teeth 221.

[0034] After the coarse crushing unit 1 cuts the rod-shaped by-product into cylindrical segments, these segments fall from the discharge end of the coarse crushing unit 1 under their own gravity, entering the V-shaped opening formed by the adjacent separating teeth 221 of the guide separating tooth assembly 22. At this time, the inclined inner wall of the V-shaped opening guides and limits the cylindrical segments. Simultaneously, the inclined edge of the separating teeth 221 expands their effective utilization range, allowing a larger cutting edge to participate in the separating operation. When the adaptive clamping and separating assembly 23 applies a downward clamping and conveying force to the cylindrical segments, the inclined cutting edge of the separating teeth 221 works in conjunction with the clamping and conveying force and the limiting force of the V-shaped opening to more efficiently separate the cylindrical segments into two halves along their axial symmetry plane, ensuring a smooth and precise separating process. The guide gear assembly 22 expands the effective working range by using multiple equally spaced gear teeth 221 and an upward-facing V-shaped opening design, thereby enabling a larger cutting edge on the gear teeth 221 to participate in the gearing and improving the gearing efficiency.

[0035] Reference Figure 2 and Figure 6 As shown: The adaptive clamping and dispensing assembly 23 includes a clamping and conveying assembly 231 and an elastic abutment assembly 232; the clamping and conveying assembly 231 is used to apply a downward clamping and conveying force to the cylindrical segment; the elastic abutment assembly 232 is used to push the clamping and conveying assembly 231 to press against the cylindrical segment in the middle of the frame 21.

[0036] As the semi-cylindrical segments fall from the coarse crushing unit 1 into the V-shaped opening of the guide and separating tooth assembly 22, the elastic abutment component 232 continuously applies a thrust towards the center of the frame 21 to the clamping and conveying component 231, ensuring a tight fit between the clamping and conveying component 231 and the surface of the semi-cylindrical segments. Because the elastic abutment component 232 possesses elastic adaptive characteristics, when the diameter of the semi-cylindrical segments differs, the elastic abutment component 232 can use its own elastic deformation to flexibly adjust the spacing of the clamping and conveying component 231 in the horizontal direction, adapting to semi-cylindrical segments of different diameters. This avoids situations where the spacing is too large for effective clamping or too small to cause material damage. While the elastic abutment component 232 pushes the clamping and conveying component 231 to press against the cylindrical segment, the clamping and conveying component 231 is simultaneously activated, applying a downward clamping and conveying force to the cylindrical segment. This clamping and conveying force works in conjunction with the limiting force of the guide and distribution tooth assembly 22 to move the cylindrical segment downward while maintaining its stable posture, thus completing adaptive clamping and stable conveying and ensuring the subsequent axial distribution operation of the cylindrical segment. The adaptive clamping and distribution component 23, through the functional separation and coordinated cooperation of the clamping and conveying component 231 and the elastic abutment component 232, and with the help of the elastic thrust of the elastic abutment component 232, achieves adaptive adaptation to cylindrical segments of different diameters.

[0037] Reference Figure 6 and Figure 7 As shown: The clamping and conveying assembly 231 includes an annular clamping belt 2311, the conveying surface of the annular clamping belt 2311 is parallel to the guide tooth assembly 22, and the conveying surface of the annular clamping belt 2311 extends from the upper end of the guide tooth assembly 22 to the lower end of the guide tooth assembly 22.

[0038] When the elastic abutment component 232 pushes the clamping and conveying component 231 to press against the cylindrical segment in the middle of the frame 21, the annular clamping belt 2311 starts and continues to operate simultaneously, with its conveying surface in close contact with the surface of the cylindrical segment. Throughout the downward movement of the cylindrical segment, the annular clamping belt 2311 provides a continuous and stable clamping force. Because the conveying surface is parallel to the distributing direction of the guide distributing tooth assembly 22 and covers the entire distributing stroke, the cylindrical segment can maintain a stable posture corresponding to the guide distributing tooth assembly 22 throughout the entire distributing stroke from the upper end to the lower end of the guide distributing tooth assembly 22, without deviation or tilting, until the cylindrical segment is completely separated along the axial symmetry plane. The annular clamping belt 2311 adopts a long-stroke design that is parallel to the guide distributing tooth assembly 22 and covers its entire distributing stroke, which can continuously provide a uniform clamping force throughout the entire distributing process of the cylindrical segment, ensuring that the material maintains a stable posture throughout the entire stroke, thereby avoiding disassembly failure caused by material posture deviation during the distributing process.

[0039] Reference Figure 7As shown: The conveying surface of the annular clamping belt 2311 is provided with multiple anti-slip teeth 2312 at equal intervals to enhance the downward clamping and conveying force on the cylindrical segments.

[0040] During the operation of the annular clamping belt 2311 and the application of downward clamping and conveying force to the cylindrical segment, the anti-slip teeth 2312 embed into the gaps on the surface of the cylindrical segment, significantly increasing the contact friction between the annular clamping belt 2311 and the cylindrical segment. This replaces the simple surface contact of the smooth conveying surface, allowing the clamping force to be transmitted more stably to the cylindrical segment. As the cylindrical segment completes its full-stroke axial distribution along the guide tooth assembly 22, the downward clamping and conveying force is continuously enhanced, effectively preventing relative slippage between the cylindrical segment and the annular clamping belt 2311. The anti-slip teeth 2312 on the conveying surface of the annular clamping belt 2311 increase the contact friction through mechanical interlocking, significantly enhancing the downward clamping and conveying force on the cylindrical segment. This fundamentally solves the problem of material slippage during distribution, ensuring stable transmission of the clamping and conveying force.

[0041] Reference Figure 6 and Figure 8 As shown: The elastic abutment component 232 includes a guide rod 2321 and a spring 2322; the guide rod 2321 is slidably connected to the frame 21, and one end of it is connected to the clamping and conveying component 231; the spring 2322 is used to provide a thrust to the clamping and conveying component 231 toward the middle of the frame 21.

[0042] In the initial state, under the thrust of the spring 2322, the two sides clamping and conveying components 231 move closer to each other, maintaining a narrow gap. When the coarsely crushed cylindrical segments fall to the upper area of ​​the two clamping and conveying components 231, the cylindrical segments come into contact with the clamping and conveying components 231 and are guided by their force, gradually entering the clamping area between the two clamping and conveying components 231. If the diameter of the cylindrical segments is larger than the initial distance between the two clamping and conveying components 231, the cylindrical segments will exert a horizontal outward squeezing force on the clamping and conveying components 231. This squeezing force is transmitted through the clamping and conveying components 231 to the guide rod 2321 and the spring 2322, causing the spring 2322 to undergo elastic deformation. At the same time, the guide rod 2321 slides horizontally outward along the frame 21, causing the clamping and conveying components 231 on both sides to move away from each other synchronously until the clamping and conveying components 231 are in close contact with the surface of the cylindrical segments. At this time, the elastic reaction force of the spring 2322 is transmitted through the guide rod 2321 to the clamping and conveying components 231, so that it continues to press against the cylindrical segments, completing the adaptive clamping and adaptation of cylindrical segments of different diameters. The elastic abutment component 232 achieves adaptive adjustment of the spacing between the clamping and conveying components 231 by means of the mechanical cooperation between the guide rod 2321 and the spring 2322, and by utilizing the elastic deformation of the spring 2322 and the horizontal sliding guidance of the guide rod 2321.

[0043] Reference Figure 2 and Figure 9 As shown: The axial distribution unit 2 also includes a feed hopper 24, the upper inlet of which is connected to the coarse crushing unit 1, and the lower outlet of which is located between the two adaptive clamping distribution components 23.

[0044] After the coarse crushing unit 1 completes the cutting of rod-shaped by-products into cylindrical segments, these segments are discharged from the outlet of the coarse crushing unit 1 and directly enter the upper inlet of the feed hopper 24 connected to it. The feed hopper 24 centrally collects the coarsely crushed cylindrical segments, preventing the material from scattering. Subsequently, under its own gravity, the cylindrical segments slide downwards along the inner wall of the feed hopper 24 and, guided by the directional direction of the lower outlet of the feed hopper 24, fall into the central feeding area between the two adaptive clamping and distributing components 23. Simultaneously, they align with the guide distributing teeth 22 below, ensuring that the cylindrical segments directly enter the collaborative working area of ​​the adaptive clamping and distributing components 23 and the guide distributing teeth 22, preparing the material for subsequent adaptive clamping and axial distributing operations. The feed hopper 24, through its upper and lower connections with the coarse crushing unit 1 and the two adaptive clamping and distributing components 23 respectively, achieves centralized collection and directional guidance of the coarsely crushed cylindrical segments.

[0045] Reference Figure 2 and Figure 10 As shown: The coarse crushing unit 1 includes two sets of coarse shearing rollers 11 rotating in opposite directions, used to cut rod-shaped by-products into cylindrical segments.

[0046] When rod-shaped agricultural processing byproducts are fed into the coarse crushing unit 1, the material falls into the gap between the two sets of coarse shearing rollers 11 under the influence of its own gravity and the suction force of the rotating cutter rollers. At this time, the coarse shearing rollers 11 rotating in opposite directions generate shearing force through their meshing blades, continuously shearing and cutting the rod-shaped byproducts that have entered the gap. The long rod-shaped byproducts are cut into cylindrical segments. After being cut, the cylindrical segments are discharged from the discharge end of the coarse shearing rollers 11 as the rollers rotate, and enter the subsequent axial sorting unit 2. The coarse crushing unit 1 achieves continuous material processing through the structure of two sets of parallel, oppositely rotating coarse shearing rollers 11 with meshing blades.

[0047] Reference Figure 2 and Figure 11 As shown: The fine crushing unit 3 includes two sets of fine crushing blade rollers 31 rotating in opposite directions, used to shear and crush semi-cylindrical materials.

[0048] When the axial separating unit 2 completes the axial separating of the semi-cylindrical segments, the resulting semi-cylindrical material falls into the gap between the two sets of fine crushing rollers 31 under gravity. The opposing fine crushing rollers 31 form a dense and uniform shearing force through their meshing fine teeth, continuously and finely shearing and crushing the semi-cylindrical material. Compared to the unseparated semi-cylindrical segments, the semi-cylindrical material has a larger contact area with the fine teeth and is subjected to more uniform force, allowing it to be quickly sheared into fine particles that meet the requirements for agricultural by-product recycling. The finished particles after crushing are discharged from the discharge end of the fine crushing rollers 31 as the rollers rotate, completing the entire crushing process. The fine crushing unit 3 achieves efficient and fine crushing of semi-cylindrical materials through the structure of two sets of parallel, opposing, meshing fine crushing rollers 31.

[0049] A method for processing agricultural by-products, applied to a crushing and processing equipment for recycling agricultural by-products, includes the following steps: S1. The rod-shaped agricultural product processing by-product is fed into the coarse crushing unit 1, and the coarse crushing unit 1 cuts the rod-shaped agricultural product processing by-product into cylindrical segments. S2. The cylindrical segment falls between the two adaptive clamping and distributing components 23 under the action of gravity, and the guide distributing tooth group 22 forms an abutment limit on the cylindrical segment. S3. The two adaptive clamping and distributing components 23 simultaneously apply a downward clamping and conveying force to the cylindrical segment. This force forms a reverse force with the abutting force of the guide distributing tooth group 22. The two work together to divide the cylindrical segment into two halves along the axial symmetry plane. S4. The semi-cylindrical material, divided into two halves, falls into the fine grinding unit 3, where it undergoes fine grinding.

[0050] The above embodiments only illustrate one or more implementation methods of this invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this invention, and these all fall within the protection scope of this invention.
