Description

Technical Field

[0001] The present invention belongs to the technical field of feed processing, and particularly relates to a forage processing device with multi-stage screening. Background Art

[0002] Forage processing is an important production link in agriculture and animal husbandry. Its purpose is to process natural forages (such as forage grass, straw, etc.) to meet the needs of storage, transportation, or further processing. However, in the actual processing process, various impurities are often mixed in the forage, such as stones, metal fragments, plastic products, undigested seeds, etc. These impurities not only affect the quality of the forage but may also cause wear and blockage of the processing equipment, and even pose safety hazards. Therefore, how to effectively remove impurities from forage has always been the focus of research and improvement in forage processing technology.

[0003] In practical applications, the sources of impurities in forage are diverse, including foreign objects in the natural environment (such as stones, branches, etc.), crop residues (such as undigested seeds in straw), and sundries introduced during manual harvesting (such as metal fragments, plastic bags, etc.). These impurities are mixed in the forage, not only affecting the quality of the forage but may also cause damage to subsequent processing equipment. For example, metal fragments may damage the cutting tools of the crusher, stones may cause the sieve mesh to become blocked, and plastic products may affect the edibility and nutritional value of the forage. Thus, a forage processing device with multi-stage screening came into being. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the present invention provides a forage processing device with multi-stage screening. The specific technical solutions are as follows: The present invention provides a forage processing device with multi-stage screening, including a main frame for carrying and towing components. The towing component is connected with a sieve roller component for multi-stage screening of forage, and a synchronization mechanism is arranged on its outer side for driving. The towing component includes a first towing belt and a second towing belt arranged on the main frame, and a return chute is arranged between them; The sieve roller component includes a roller pressing mechanism connected to the first towing belt. A screening and scattering mechanism is arranged behind it, and a box cover is provided on the top of the screening and scattering mechanism; The roller pressing mechanism includes symmetrically arranged guide seats, and a rotatable cylindrical primary roller is horizontally inserted between them and is vertically butted. Vertical lines are provided on the outer peripheral surface of the primary roller to squeeze the forage as the primary roller rotates; The screening and scattering mechanism includes a screening and scattering shaft horizontally inserted on the side of the box cover. A plurality of screening and scattering rings are sleeved on it, and screening and scattering sheets are arranged on the outer periphery of the screening and scattering ring in the middle to receive the forage and rotate it for screening and scattering, and then transfer it to the second towing belt for discharging.

[0005] As a preferred technical solution of the present invention, a compound roller clamped up and down is arranged between the guide seats, which rotates synchronously behind the primary roller. The outer periphery of the compound roller is provided with rolling patterns based on the central axis, which extend obliquely to both sides and compress and crush the forage as the compound roller rotates, for secondary combing of the forage.

[0006] As a preferred technical solution of the present invention, the sieve and scatter plates are arranged horizontally at right angles and rotate counterclockwise with the sieve and scatter ring, for sieving, separating and transporting the crushed forage. And a sieve grid is obliquely inserted below the sieve and scatter ring, and a slag discharge box that can be drawn out is arranged at the bottom thereof, for removing and collecting the impurities of the forage.

[0007] As a preferred technical solution of the present invention, a drying and rolling mechanism is arranged at the bottom of the sieve and scatter mechanism, which includes a lower cylinder inserted at the end of the second traction belt. A rotatable upper cylinder is erected obliquely above the lower cylinder, and a second traction belt rotates cyclically between them, for receiving the formed discharge of the sieved and scattered forage.

[0008] As a preferred technical solution of the present invention, the guide seat is designed in an L-shaped structure, with a large fixed hole provided at its lower part, a synchronous wheel coupled and connected to the outside thereof, and a sliding hole for moving up and down provided above the large fixed hole, for inserting the primary roller and the compound roller. A tightening bolt is inserted at the top of the sliding hole and connected to the sliding hole, and a compression spring is arranged therebetween. The dynamic gap of the roller is adjusted by rotating the tightening bolt, for the safety protection of the rolling mechanism.

[0009] As a preferred technical solution of the present invention, the second traction belt is erected obliquely upward, and a hollow anti-tangling roller that can rotate synchronously is suspended at its front end, for the lossless discharge of the forage as the second traction belt rotates.

[0010] As a preferred technical solution of the present invention, a circumferentially arranged rotating shaft is inserted on the outer periphery of the anti-tangling roller, and they rotate independently respectively, for the non-adhesive discharge of the forage.

[0011] As a preferred technical solution of the present invention, the synchronization mechanism includes a motor arranged at the bottom of the main frame, with a first belt pulley arranged upward. The first belt pulley is sleeved with a transmission shaft, and second belt pulleys and first chain wheels are respectively connected to the sieve and scatter shaft and the lower cylinder at the coaxial front end thereof. Gear transmissions are arranged at the ends of the lower cylinder and the upper cylinder, and the front end roller of the second traction belt is driven to rotate by the second traction belt. A fifth chain wheel is connected between the front end roller of the second traction belt and the anti-tangling roller for synchronous rotation, and a second chain wheel is sleeved between the upper cylinder and the synchronous wheel to drive the rolling mechanism to rotate. Third chain wheels are arranged at the coaxial ends of the primary roller and the compound roller, and a fourth chain wheel is sleeved with the roller of the first traction belt for traction and rolling, for the synchronous transmission of the equipment.

[0012] As a preferred technical solution of the present invention, the drying and rolling mechanism includes a wing-shaped cylinder base, which is provided with a small fixed hole for inserting the lower cylinder at its lower end. The upper end of the cylinder base is provided with a limit hole that can move obliquely, and an upper cylinder is inserted therein. There is a speed control knob connected to the limit hole from the upper end to adjust the gap between the upper cylinder and the lower cylinder in the direction of the forage discharge, for controlling the moisture content of the forage.

[0013] As a preferred technical solution of the present invention, a baffle is inserted outside the sieve grid to prevent the forage from falling out of the main frame as it sifts and scatters.

[0014] The beneficial effects of the present invention are as follows: I. High efficient impurity removal ability Traditional forage processing equipment has great limitations in impurity removal and often cannot completely remove impurities such as stones and metal fragments in the forage. These impurities not only affect the quality of the forage but also may damage subsequent processing equipment and increase potential safety hazards. However, through the design of multi-stage screening, the impurity removal effect of this equipment has been significantly improved.

[0015] Firstly, the equipment adopts a rolling mechanism. The outer peripheral surface of the primary roller is provided with vertical lines, which can rotate and squeeze the forage to initially separate the larger impurities therein. This design utilizes the mechanical friction and extrusion crushing effects to effectively remove larger foreign objects such as stones and branches mixed in the forage.

[0016] Secondly, through the rotating screening effect of the screening shaft and the screening ring of the screening mechanism, the forage is further refined to ensure that even smaller impurities are completely removed. The design of the screening pieces can effectively crush and screen out fine particle impurities in the forage, such as small stones and plastic products.

[0017] Through the dual effects of rolling and screening, the equipment can comprehensively remove impurities of different sizes and shapes in the forage, significantly improving the purity of the forage.

[0018] II. Improvement of processing efficiency This equipment adopts a driving method of traction belts and a synchronization mechanism to ensure the orderly flow and stable transmission of the forage during the processing. The design of the return chute between the first traction belt and the second traction belt can effectively guide the flow direction of the forage and prevent the forage from accumulating and blocking inside the equipment.

[0019] The coordinated operation of the rolling mechanism and the screening mechanism enables the forage to evenly enter the screening mechanism for further screening after being rolled and extruded. This highly efficient screening process not only improves the processing speed of the forage but also ensures the full utilization of the forage in each processing link.

[0020] Furthermore, the machine's multi-stage screening design allows for simultaneous processing of large quantities of forage, significantly improving overall processing efficiency. By optimizing the flow path of forage and minimizing downtime, this machine is able to meet the needs of large-scale forage processing.

[0021] 3. Enhance the stability and reliability of equipment The equipment features symmetrically arranged guides and a design where the primary rollers are butted against each other, ensuring stable operation of the rolling mechanism. The vertical grooves on the primary rollers evenly apply pressure to crush impurities, preventing forage from shifting or misaligning during the rolling process.

[0022] The sifting mechanism's housing effectively prevents the forage from scattering during the sifting process, keeping the processing environment clean. The rational layout of the sifting shaft and sifting ring ensures uniform distribution and efficient sifting of the forage.

[0023] The synchronous drive mechanism enables the traction belt and screen roller assembly to operate synchronously, avoiding the accumulation or leakage of forage caused by speed mismatch. This design significantly improves the operational stability and reliability of the equipment and reduces the incidence of equipment failure.

[0024] 4. Flexibility and Adaptability The multi-stage screening design of this equipment allows it to adapt to the processing needs of different types and qualities of forage. Whether it is forage grass, straw or silage, the equipment can achieve efficient impurity removal and forage processing by adjusting the roller pressure and screening parameters.

[0025] Furthermore, the machine's flexible structural design allows for easy adjustment and optimization based on actual processing needs. For example, by replacing the sifting discs with different specifications, it can adapt to the screening requirements of different forage particle sizes. This flexibility enables the machine to perform optimally in various production scenarios.

[0026] In summary, forage processing equipment with multi-stage screening offers significant benefits in terms of impurity removal, processing efficiency, equipment stability, and energy conservation and environmental protection. Through the dual effects of rolling and screening, the equipment can completely remove impurities of varying sizes and shapes from forage, significantly improving its purity. Furthermore, the equipment's efficient screening process and optimized design significantly enhance overall processing efficiency and operational stability. Furthermore, the equipment's flexibility and energy-saving and environmentally friendly features enable it to adapt to the needs of diverse production scenarios, promoting the sustainable development of the forage processing industry.

Detailed implementation manners

[0028] In order to make the purpose, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] Embodiment 1 To solve the technical problems in the background art, the following forage processing equipment with multi-stage screening is given: Combined with Figure 1-8As shown in the figure, a forage processing device with multi-stage screening includes a main frame 1 that bears a traction assembly 2. The traction assembly 2 is connected with a sieve roller assembly 3 for multi-stage screening of forage, and a synchronization mechanism 4 is arranged outside it for driving. The traction assembly 2 includes a first traction belt 21 and a second traction belt 22 arranged on the main frame 1, and a return chute 23 is arranged between them; The sieve roller assembly 3 includes a roller pressing mechanism 32 connected to the first traction belt 21. A screening and scattering mechanism 33 is arranged behind it, and a box cover 31 is covered on the top of the screening and scattering mechanism 33; The roller pressing mechanism 32 includes symmetrically arranged guide seats 323, and a rotatable cylindrical primary roller 321 is horizontally inserted between them in an up-and-down docking manner. Vertical lines are arranged on the outer peripheral surface of the primary roller 321, and the forage is squeezed and broken as the primary roller 321 rotates; The screening and scattering mechanism 33 includes a screening and scattering shaft 331 horizontally inserted on the side of the box cover 31. A plurality of screening and scattering rings 332 are sleeved on it, and screening and scattering pieces 3321 are arranged on the outer periphery of the screening and scattering ring 332 in the middle. The forage is received and rotated and screened, and then transported to the second traction belt 22 for discharging.

[0030] Please refer to the attached instruction manual Figure 1-8 In this embodiment, a forage processing device with multi-stage screening realizes the efficient processing and screening of forage through a clever structural design. The device is mainly composed of a main frame 1 that bears a traction assembly 2. The traction assembly 2 is connected with a sieve roller assembly 3 for multi-stage screening of forage, and a synchronization mechanism 4 is arranged outside it for driving. The traction assembly 2 includes a first traction belt 21 and a second traction belt 22 arranged on the main frame 1, and a return chute 23 is arranged between the two for the transfer and flow of forage.

[0031] The sieve roller assembly 3 is the core part of this device. First, it includes a roller pressing mechanism 32 connected to the first traction belt 21. The roller pressing mechanism 32 is composed of symmetrically arranged guide seats 323, and a rotatable cylindrical primary roller 321 is horizontally inserted between them in an up-and-down docking manner. Vertical lines are arranged on the outer peripheral surface of the primary roller 321, and the forage is squeezed and broken during the rotation of the primary roller 321, completing the preliminary combing and processing. This design enables the forage to be effectively broken before entering the subsequent screening stage, facilitating the operation of the subsequent screening and scattering mechanism 33.

[0032] After the rolling mechanism 32, a screening and dispersing mechanism 33 is provided, and a box cover 31 is provided on the top of the screening and dispersing mechanism 33. The screening and dispersing mechanism 33 includes a screening and dispersing shaft 331 horizontally inserted into the side of the box cover 31, and a plurality of screening and dispersing rings 332 are sleeved thereon. The design of the screening and dispersing rings 332 enables the forage to be fully screened and dispersed during rotation. Screening and dispersing pieces 3321 are arranged on the outer periphery of the screening and dispersing rings 332 in the middle of the screening and dispersing rings 332, further improving the dispersing effect of the forage. The screening and dispersing pieces 3321 receive the forage during the rotation of the screening and dispersing rings 332, and synchronously remove impurities from the forage through rotational movement to ensure the purity of the forage.

[0033] After being processed by the screening and dispersing mechanism 33, the forage is transported to the discharge of the second traction belt 22. The second traction belt 22 is responsible for outputting the screened forage to the outside of the equipment to complete the entire processing process. The design of the return chute 23 ensures the smooth flow of the forage at different stages, avoids blockage and backlog problems, and further improves the processing efficiency of the equipment.

[0034] In summary, the forage processing equipment in this embodiment realizes the efficient processing and screening of forage through the design of roller pressing and crushing and screening and synchronously removing impurities. Each component of the equipment cooperates with each other to ensure the continuous flow and effective dispersion of the forage during the processing, providing a good foundation for subsequent discharging. Through this design, the equipment can process various types of forage to meet different processing requirements.

[0035] Embodiment 2 As Figure 1-6 shown, on the basis of the above embodiment, this embodiment further gives the following content: In this embodiment, a double roller 322 is clamped up and down between the guide seats 323. It is located behind the primary roller 321 and rotates synchronously. Rolling patterns 3221 are provided on the outer periphery of the double roller 322 with the central axis as the reference, and they extend obliquely to both sides. As the double roller 322 rotates, it compresses and crushes the forage for secondary combing of the forage.

[0036] The screening and dispersing pieces 3321 are arranged horizontally at a right angle. As the screening and dispersing rings 332 rotate counterclockwise, they are used for screening and transporting the crushed forage. A screen grid 35 is obliquely inserted below the screening and dispersing rings 332, and a slag discharge box 5 that can be drawn out is arranged at the bottom for removing and collecting forage impurities.

[0037] The guiding seat 323 is designed with an L-shaped structure. A large fixed hole 3231 is provided at its lower part, and a synchronous pulley 324 is coupled and connected to its outer side. A sliding hole 3232 for vertical movement is provided above the large fixed hole 3231 for inserting the primary roller 321 and the secondary roller 322. A tightening bolt 3234 is inserted at the top of the sliding hole 3232 and connected to the sliding hole 3232, and a compression spring 3233 is arranged therebetween to adjust the dynamic gap of the roller by rotating the tightening bolt 3234, which is used for the safety protection of the rolling mechanism 32.

[0038] Please refer to the attached instructions Figure 1-6 , the present invention provides a second embodiment of the forage processing device. In this embodiment, the device realizes the refined screening treatment of forage and the efficient discharge of impurities through the combined action of the primary roller 321 for rolling and crushing, the secondary roller 322 for secondary combing, and the dynamic adjustment of the compression spring 3233. The specific implementation method is as follows: In this embodiment, the guiding seat 323 is designed with an L-shaped structure. A large fixed hole 3231 is opened at its lower part and power transmission is realized through the synchronous pulley 324. A vertical sliding hole 3232 is provided above the large fixed hole 3231, and the primary roller 321 and the secondary roller 322 are inserted vertically and parallelly into the sliding hole 3232. The primary roller 321 is located in front of the secondary roller 322, and the two are driven to rotate at the same speed through the synchronous pulley 324. The outer circumference of the secondary roller 322 is processed with rolling lines 3221 symmetrically distributed with respect to the central axis, and the rolling lines 3221 extend obliquely to both sides to form an obtuse angle. When the forage is initially rolled by the primary roller 321 and enters the area of the rolling lines 3221 of the secondary roller 322, the oblique lines exert a transverse shearing force on the forage fibers during rotation, forcing the entangled forage to unfold along the direction of the lines to complete secondary combing.

[0039] Preferably, a tightening bolt 3234 is installed at the top of the sliding hole 3232. The tightening bolt 3234 is threadedly connected to the inner wall of the sliding hole 3232, and a compression spring 3233 is arranged therebetween. When the impurity content of the forage suddenly increases and becomes unstable, the primary roller 321 and the secondary roller 322 at the upper end are abnormally squeezed. Under the pre-tightening force of the tightening bolt 3234, the compression spring 3233 undergoes elastic deformation, driving the primary roller 321 and the secondary roller 322 to move upward along the sliding hole 3232 to expand the gap between the two rollers to release the pressure. At the same time, the primary roller 321 and the secondary roller 322 increase the torque to crush hard impurities. After the impurities are discharged, the compression spring 3233 rebounds and resets to ensure the continuous and efficient operation of the rollers. A scale disk is provided at the outer end of the tightening bolt 3234. The operator can precisely adjust the pre-tightening force of the compression spring 3233 by rotating the tightening bolt 3234, set a safety threshold corresponding to different forage hardnesses. For hard forage (such as bamboo leaves), a high pre-tightening force is adopted to maintain the rolling strength, while for soft forage (such as alfalfa), the pre-tightening force is reduced to avoid fiber damage.

[0040] Furthermore, the sifting discs 3321 are arranged horizontally at right angles and welded perpendicularly to the outer edge of the sifting ring 332. When the sifting ring 332 rotates counterclockwise, the sifting discs 3321 strike the forage at a tangential direction. Small impurities are ejected to the outside of the sifting ring 332 due to inertia, and qualified forage is ejected. A sieve grid 35 is inserted obliquely below the sifting ring 332. The inclination angle of the sieve grid 35 is staggered with the ejection angle of the sifting ring 332. As the forage slides along the inclined surface of the sieve grid 35, fine impurities (such as sand, gravel, and soil particles) pass through the sieve holes and fall into the retractable slag box 5 at the bottom. The clean material is then directed to the second traction belt 22. A transparent observation window is embedded in the side wall of the slag box 5, allowing the operator to visually determine the cleaning cycle by observing the height of the impurity accumulation.

[0041] During implementation, the grass first enters the crushing zone formed by the primary roller 321 and the secondary roller 322. The primary roller 321 coarsely crushes the grass at a high speed, while the secondary roller 322 combs and spreads the grass fibers horizontally using diagonal crushing patterns 3221. The gap between the two rollers is dynamically adjusted by a compression spring 3233. When hard grass, such as corn stalks, enters, the compression spring 3233 maintains a fixed gap to ensure crushing force. When processing easily tangled vines, the compression spring 3233 allows the gap to expand momentarily to prevent jamming. The sifting ring 332 rotates counterclockwise, and the sifting discs 3321 centrifugally disperse the crushed and combed grass. Impurities are filtered through the sieve 35 and enter the slag box 5. The clean material enters the subsequent drying and forming process. The entire system achieves both high efficiency and safety during the grass processing process through the coordinated mechanism of two-stage crushing by the primary roller 321 and the secondary roller 322, dynamic sorting by the sifting discs 3321, and elastic protection by the compression spring 3233.

[0042] Example 3 like Figure 1-11 As shown, based on the above embodiment, this embodiment further provides the following content: In this embodiment, a grinding mechanism 34 is provided at the bottom of the screening mechanism 33, which includes a lower cylinder 342 inserted at the end of the second traction belt 22, and a rotatable upper cylinder 341 is mounted obliquely above the lower cylinder 342, and the second traction belt 22 circulates and rotates between them to receive the shaped discharge of the screened grass.

[0043] The second traction belt 22 is erected obliquely upward, and a hollow anti-entanglement roller 24 that can rotate synchronously is suspended at the front end thereof, which rotates with the second traction belt 22 to achieve lossless discharge of grass and fodder.

[0044] A circumferentially arranged rotating shaft 241 is inserted into the outer periphery of the anti-entanglement roller 24, which rotates independently to discharge the grass without adhesion.

[0045] The drying and rolling mechanism 34 includes a wing-shaped cylinder base 343, at the lower end of which there is a small fixed hole 3431 for inserting the lower cylinder 342. At the upper end of the cylinder base 343, there is an obliquely movable limiting hole 3432, in which the upper cylinder 341 is inserted, and a speed control knob 3433 is connected to the limiting hole 3432 from the upper end, so as to adjust the gap between the upper cylinder 341 and the lower cylinder 342 in the direction of the forage discharge to control the moisture content of the forage.

[0046] A baffle 36 is inserted outside the sieve grid 35 to prevent the forage from falling out of the main frame 1 as it sifts and falls.

[0047] Please refer to the attached instruction manual Figure 1-11 Referring to the attached drawings, the present invention provides a third embodiment of a forage processing device. In this embodiment, a drying and rolling mechanism 34 is added to the bottom of the sifting mechanism 33. Through a collaborative mechanism in which the rolling mechanism 32 dynamically extrudes to remove large impurities, the sifting mechanism 33 centrifugally rotates to remove small impurities, and the drying and rolling mechanism 34 statically rolls to form the discharged material, the entire process of forage processing is completed.

[0048] In this embodiment, a drying and rolling mechanism 34 is arranged at the bottom of the sifting mechanism 33. The drying and rolling mechanism 34 includes a lower cylinder 342 obliquely inserted at the end of the second traction belt 22, and an upper cylinder 341 that is rotatably mounted obliquely above the lower cylinder 342. The second traction belt 22 is arranged in an obliquely upward inclined posture, and a hollow anti-tangling roller 24 is suspended at its front end. The anti-tangling roller 24 rotates synchronously with the second traction belt 22. The forage sorted by the sifting mechanism 33 falls onto the surface of the second traction belt 22, and as the second traction belt 22 conveys obliquely, the forage is smoothly transferred to the rolling area between the lower cylinder 342 and the upper cylinder 341. A number of independently rotating rotating shafts 241 are inserted circumferentially on the outer circumference of the anti-tangling roller 24. When the forage contacts the anti-tangling roller 24, the rotating shafts 241 cancel the adhesion force between the forage and the roller surface through self-rotation, realizing non-sticky discharge.

[0049] Preferably, the drying and rolling mechanism 34 uses a wing-shaped cylinder base 343 as the supporting main body. A small fixed hole 3431 is opened at the lower end of the wing-shaped cylinder base 343, and the lower cylinder 342 is fixed in the small fixed hole 3431 by interference fit. An obliquely extending limiting hole 3432 is arranged at the upper end of the cylinder base 343, and the support shaft of the upper cylinder 341 is inserted into the limiting hole 3432. The top end of the support shaft is connected to the speed control knob 3433. The operator can rotate the speed control knob 3433 to drive the upper cylinder 341 to move obliquely along the limiting hole 3432, thereby adjusting the static gap between the upper cylinder 341 and the lower cylinder 342. When the forage enters the rolling area, the upper cylinder 341 and the lower cylinder 342 form a constant pressure on the forage, and the forage fibers discharge excess moisture and form under the action of static rolling. The gap adjustment range is set according to the moisture content of the forage. For high-humidity forage, a smaller gap is used to enhance the dehydration effect, while for low-humidity forage, the gap is appropriately increased to avoid over-compaction.

[0050] Further, a detachable baffle 36 is vertically inserted outside the sieve grid 35, and the height of the baffle 36 is flush with the edge of the sieve grid 35. When the sieve and scatter mechanism 33 rotates counterclockwise, the baffle 36 blocks the forage from flying out due to the centrifugal force, ensuring that the forage slides along the inclined plane of the sieve grid 35 to the second traction belt 22. The baffle 36 is designed with an arc-shaped curved surface, and its concave surface matches the rotation trajectory of the sieve and scatter ring 332, which not only avoids the accumulation of forage but also reduces the influence of air flow disturbance on the screening accuracy.

[0051] During specific implementation, after the forage is crushed and impurity-removed by the roller pressing mechanism 32, it enters the sieve and scatter mechanism 33. The centrifugally rotating sieve and scatter plates 3321 separate the impurities into the slag discharge box 5, and the qualified forage slides down to the second traction belt 22. The second traction belt 22 obliquely conveys the forage at a constant speed, and the anti-winding roller 24 rotates around its rotating shaft 241 to eliminate the risk of forage winding. Then the forage enters the rolling area formed by the upper cylinder 341 and the lower cylinder 342. The wing-shaped cylinder seat 343 adjusts the rolling pressure in real time through the speed control knob 3433, and the static roller pressing makes the forage fibers arranged in a direction and formed. The baffle 36 restricts the movement trajectory of the forage throughout the process, preventing the material from escaping during the processing. The whole set of equipment realizes the operation goals of continuous processing, low loss, and high forming degree of forage through multi-stage processing of dynamic extrusion, centrifugal separation, and static forming.

[0054] In this embodiment, the synchronous mechanism 4 is provided with a motor 6 at the bottom of the main frame 1 to provide power for the entire system. The motor 6 is connected upward with a first pulley 41, and the first pulley 41 transmits power to other parts of the equipment through a transmission shaft. The coaxial ends of the transmission shaft are respectively connected to the screening and dispersing shaft 331 and the lower cylinder 342, and power transmission is achieved through the second pulley 42 and the first sprocket 43. A gear transmission system is provided at the ends of the lower cylinder 342 and the upper cylinder 341, and the front roller is driven to rotate through the second traction belt 22 to ensure the smooth flow of forage during the processing.

[0055] The front roller of the second traction belt 22 is connected to the anti-tangling roller 24 through a fifth sprocket 47 to achieve synchronous rotation. The design of the anti-tangling roller 24 is aimed at preventing the forage from being entangled during transmission, so as to achieve lossless discharge of the forage. A second sprocket 44 is sleeved between the upper cylinder 341 and the synchronous pulley 324 to drive the rotation of the roller pressing mechanism 32. The design of the roller pressing mechanism 32 realizes the preliminary crushing and secondary combing of the forage through the coordinated action of the primary roller 321 and the secondary roller 322.

Through this system design, the equipment can ensure the coordinated operation of each component during the forage processing, and reduce the loss of forage during the processing.

[0057] The design of the entire synchronous mechanism 4 is aimed at realizing the system synchronous operation of the forage processing equipment through the precise cooperation of the pulley and sprocket systems. The power transmission and motion coordination between each component enable the equipment to maintain a consistent working rhythm at different processing stages, ensuring the efficient processing and transmission of forage.

[0058] In summary, the forage processing equipment in this embodiment realizes the efficient processing and transmission of forage through the design of system synchronous operation. Each component of the equipment cooperates with each other to ensure the continuous flow and effective processing of forage during the processing. Through this design, the equipment can process various types of forage, meet different processing requirements, and at the same time reduce the loss of forage during the processing, providing a solid foundation for the further processing and utilization of forage.

[0059] Working principle and usage process of the present invention: Start the equipment: First, start the motor 6 at the bottom of the main frame 1 to ensure that the synchronous mechanism 4 is in a working state. The motor 6 drives the transmission shaft through the first pulley 41 to provide power for each component of the equipment.

[0060] Forage conveying: The first conveyor belt 21 starts and runs on the main frame 1 of the equipment to convey forage to the rolling mechanism 32. The rollers of the first conveyor belt 21 are connected to the third sprockets 45 of the primary roller 321 and the secondary roller 322 through the fourth sprocket 46 to ensure synchronous transmission.

[0061] Forage rolling: The forage enters the rolling mechanism 32 and first undergoes the treatment of the primary roller 321, which squeezes the forage by rotation. Subsequently, the forage is conveyed to the secondary roller 322 with an inclined rolling pattern 3221 for secondary combing of the forage.

[0062] Forage screening and scattering: The rolled forage enters the screening and scattering mechanism 33. A plurality of screening and scattering rings 332 are sleeved on the screening and scattering shaft 331 of the screening and scattering mechanism 33, and screening and scattering blades 3321 are horizontally inserted on the screening and scattering rings 332. The forage rotates and scatters under the action of the screening and scattering blades 3321 and slides through the screening grid 35 for screening and impurity removal. A slag discharge box 5 is provided at the bottom of the screening grid 35 for collecting impurities in the forage.

[0063] Forage drying: The screened and scattered forage enters the drying mechanism 34. The drying mechanism 34 consists of a lower cylinder 342 and an upper cylinder 341. The lower cylinder 342 is inserted at the end of the second conveyor belt 22. The upper cylinder 341 is rotatable and is erected obliquely above the lower cylinder 342. The gap between the upper cylinder 341 and the lower cylinder 342 is adjusted through the speed control knob 3433 to control the moisture content of the forage.

[0064] Forage discharging: The second conveyor belt 22 is erected obliquely upward to convey the forage to the discharging end. The front rollers of the conveyor belt rotate synchronously with the anti-tangling roller 24 through the fifth sprocket 47 to ensure the damage-free discharging of the forage.

[0065] Forage anti-tangling: Axles 241 arranged circumferentially are inserted on the outer periphery of the anti-tangling roller 24, and these axles 241 rotate independently to prevent the adhesion of forage during the discharging process and ensure the smooth discharge of forage from the equipment.

[0066] Completion of operation: After completing all forage processing tasks, turn off the power supply of the equipment to ensure that the equipment is in a safe state.

[0067] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
