Description

Technical Field

[0001] This invention relates to the field of shredding equipment technology, specifically to an elastic pressing type forage shredding mechanism and its forage processing device. Background Technology

[0002] In forage processing, solid fermentation and sheep pen feed production have specific requirements for the length of forage chopped. For sheep pen feed, the forage must be chopped to 3 to 5 centimeters. In northern my country, hay is often baled into blocks for easy transport. However, chopping these blocks presents several inconveniences. Existing small shredders cannot meet the processing needs of these blocks, while commonly used disc-type hay crushers, although capable of centralized crushing, are too bulky and difficult to transport, making them unsuitable for small-batch chopping by home users. Furthermore, the length of the chopped hay varies greatly, easily resulting in a mixture of long and short pieces, affecting the uniformity of feed formulation. Chinese Patent Publication No. CN117461481B discloses a hay processing device for livestock farming, comprising a housing with two V-shaped roller arrangement mechanisms installed inside. A cutting mechanism is also provided inside the housing. The roller arrangement mechanism includes several actuating rollers, a cutting roller, and a striking roller. The striking roller has a striking plate on its outer surface. An additional cutting roller is rotatably installed inside the housing near the bottom of the two roller arrangement mechanisms. While the aforementioned comparative document addresses the issue of traditional equipment being bulky and unsuitable for small-batch processing, achieving initial loosening and chopping of hay bales through the combination of V-shaped roller stacking mechanism and striking rollers, thus meeting the small-batch needs of household users to some extent, it lacks sufficient tearing and crushing ability for hard hay bales. The rigidity of the cutting roller and striking roller easily causes hard-stemmed hay to bounce, resulting in insufficient chopping in certain areas. Furthermore, it lacks adaptive adjustment for hay bales of different thicknesses, and material jamming often occurs during processing due to fluctuations in the feed rate, leading to a sharp drop in chopping efficiency. Ultimately, the produced hay still suffers from uneven lengths and hard stem residue. Summary of the Invention

[0003] To address the aforementioned issues, a flexible pressing forage chopping mechanism and its forage processing device are provided. The pressing plate switches between clamping and releasing the forage on one side, allowing for better control of the forage's posture and preventing it from bouncing due to contact with the cutting mechanism, thus ensuring proper contact. Furthermore, while clamping, the rotation of the connecting rod causes the mounting frame to swing downwards, generating a downward pushing force while the pressing plate applies clamping force, actively pressing the forage against the cutting mechanism. This improves the forage cutting effect and solves the problem of low efficiency when relying solely on gravity conveying.

[0004] To address the problems of existing technologies, this invention provides an elastic pressing forage chopping mechanism, comprising a frame and a pressing mechanism mounted on the frame. The pressing mechanism includes two mounting frames arranged in a mirror-symmetrical manner. Connecting rods are hinged to the top and bottom of each mounting frame, and the two connecting rods are parallel to each other. The other ends of the two connecting rods are rotatably mounted on the frame, allowing the two mounting frames to reciprocate relative to each other. Pressing plates are provided on opposite sides of each mounting frame, and the pressing plates are elastically connected to their respective mounting frames. A cutting mechanism is located below the two mounting frames on the frame. The oscillating motion of the cutting mechanism coordinates with that of the pressing mechanism, causing the pressing plates to alternately clamp and release the forage during the reciprocating oscillation, thus cooperating with the cutting mechanism to complete the chopping process.

[0005] Preferably, the mounting frame is provided with a support frame, and the support frame is provided with a plurality of guide rods extending in the horizontal direction. The guide rods are sleeved on the mounting frame and slide in cooperation with the mounting frame. A threaded rod that is threaded in cooperation with the mounting frame is provided in the center of the support frame. The threaded rod and the guide rods are parallel to each other.

[0006] Preferably, the top of the support frame is provided with a support shaft extending in a horizontal direction, the top of the pressure plate is rotatably connected to the support shaft, and an elastic element is provided between the bottom of the support frame and the pressure plate, so that the pressure plate is set on the support frame in an inclined position.

[0007] Preferably, the pressure plate is provided with two vertically extending slide rails at one end near the support frame, and a slider is provided on the slide rail for sliding cooperation with it. The elastic element is a telescopic elastic rod, one end of which is connected to the bottom of the support frame, and the other end of which is hinged to the slider.

[0008] Preferably, the side of the pressure plate away from the support frame has a stepped structure, and the pressure plate is provided with multiple rectangular protrusions arranged in a row.

[0009] Preferably, the cutting mechanism includes two cutting rollers that can rotate relative to each other, and each cutting roller is provided with a plurality of cutting blades that are equidistantly arranged around its axis.

[0010] Preferably, the bottom of the frame is provided with a semi-circular cavity below the cutting mechanism. Multiple through holes are evenly distributed on the outer edge of the semi-circular cavity. A kneading and cutting mechanism is provided inside the cavity. A funnel-shaped material guide channel is provided between the cavity and the frame.

[0011] Preferably, the kneading and cutting mechanism includes a rotating shaft coaxial with the axis of the cavity, and a plurality of partition plates equidistantly surrounding the axis of the rotating shaft are also provided on the rotating shaft, with serrations provided at the end of the partition plates away from the rotating shaft.

[0012] Preferably, the kneading and cutting mechanism further includes two saw blades sleeved on the rotating shaft. Between the two saw blades, there are multiple mounting shafts parallel to the axis of the rotating shaft. The number of mounting shafts is the same as the number of partition plates and corresponds one-to-one. Each mounting shaft is provided with multiple equidistant blades arranged along its axis. The blades are rotatably mounted on the mounting shaft and are provided with saw teeth.

[0013] A forage processing apparatus includes a flexible pressing forage cutting mechanism as described above.

[0014] The advantages of this invention compared to the prior art are: 1. This invention, through the design of the pressing mechanism, allows the pressing plate to switch between clamping and releasing the forage on one side. This enables the pressing plate to better control the posture of the forage, preventing it from bouncing due to contact with the cutting mechanism and ensuring contact between the forage and the cutting mechanism. Furthermore, during the clamping action, the rotation of the connecting rod also causes the entire mounting frame to swing downwards, so that the pressing plate applies clamping force while generating a downward pushing force, actively pressing the forage against the cutting mechanism. This helps to improve the cutting effect of the forage and solves the problem of low efficiency when relying solely on gravity conveying.

[0015] 2. By adjusting the setting of the pressing plate, the present invention can be flexibly adjusted according to the characteristics of the forage. When processing coarser or harder forage, it avoids jamming during feeding; when processing finer or softer forage, the spacing can be reduced to enhance the clamping effect and improve adaptability.

[0016] 3. This invention provides progressive clamping guidance for forage of different thicknesses through the stepped structure of the pressure plate, reducing the tendency of hard-stemmed forage to bounce under pressure. Meanwhile, the rectangular array of protrusions increases the coefficient of friction, further enhancing control over soft or smooth forage. The synergistic effect of these two elements ensures that the pressure plate maintains stable constraint on the forage throughout the clamping and releasing cycle. Furthermore, the combination of the stepped structure and protrusions reduces the contact area between the pressure plate and the forage, minimizing forage adhesion caused by excessive compression. Combined with the cushioning effect of the elastic element, this makes the mechanism more adaptable to various types of forage and ensures a smoother cutting process. Attached Figure Description

Detailed Implementation

[0029] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 5As shown: A flexible pressing type hay chopping mechanism includes a frame 1 and a pressing mechanism 2 mounted on the frame 1; the pressing mechanism 2 includes two mounting frames 21 arranged in a mirror symmetrical manner; the top and bottom of the two mounting frames 21 are hinged with connecting rods 211, and the two connecting rods 211 on the mounting frames 21 are parallel to each other, and the other end of the two connecting rods 211 is rotatably mounted on the frame 1, so that the two mounting frames 21 can swing back and forth relative to each other; pressing plates 23 are provided on opposite sides of the two mounting frames 21, and the pressing plates 23 are elastically connected to the corresponding mounting frames 21; A cutting mechanism 11 is provided on the frame 1 below the two mounting brackets 21. The cutting mechanism 11 works in conjunction with the swinging motion of the pressing mechanism 2, so that the pressing plate 23 alternately performs clamping and releasing actions on the forage in the reciprocating swinging motion, and completes the cutting in conjunction with the cutting mechanism 11.

[0031] When the elastic pressing type hay cutting mechanism 14 is working, hay is conveyed from the top of the frame 1 to the pressing mechanism 2. The two mounting frames 21 of the pressing mechanism 2 form a linkage structure with the frame 1 through parallel connecting rods 211 at the top and bottom. Since the two connecting rods 211 on the mounting frame 21 are of the same length and always remain parallel, and the two ends of the connecting rods 211 are hinged to the mounting frame 21 and the frame 1 respectively, when the connecting rods 211 are driven to rotate, the two mirror-symmetrical mounting frames 21 will swing back and forth relative to each other. The movement rhythm of the two mounting frames 21 is completely consistent, ensuring that the clamping force of the pressing plate 23 on the mounting frame 21 on the hay is always balanced and the hay will not be skewed due to unilateral offset.

[0032] Due to the rotation of the connecting rod 211, the pressure plate 23 switches between clamping and releasing the forage. This serves two purposes: First, for harder forage, continuous clamping can cause it to bounce off the cutting mechanism 11 upon contact, preventing it from bouncing and ensuring contact. Second, during transport, forage may accumulate due to varying loft; releasing the pressure plate provides adjustment space, preventing jamming. Third, the rotation of the connecting rod 211 causes the mounting frame 21 to swing downwards, generating a downward pushing force while applying clamping force, actively pressing the forage against the cutting mechanism 11. This improves cutting efficiency and addresses the low efficiency of gravity-based transport.

[0033] By employing the above method, it is possible to adapt to the processing needs of forage with different characteristics. For soft forage, the elastic pressure during clamping is only used to stabilize its position, rather than for strong squeezing, to avoid the forage being crushed into pieces before cutting due to excessive compaction, ensuring that it still maintains a suitable length and structure after cutting, meeting the processing standards for shredding. The gap when releasing reduces the pulling of the forage when the pressure plate 23 swings back, preventing the soft forage from being torn disorderly and ensuring that the cut edges are neat. For forage containing hard stems, this cyclical action can effectively prevent the hard stems in the forage from bouncing or shifting during cutting. When clamping, the pressure plate 23, while fixing the position of the hard stem, generates a downward pushing force as the connecting rod 211 rotates, pressing the hard stem steadily against the cutting mechanism 11, ensuring contact with the cutting blade 1111. When releasing, it releases the elastic tension of the hard stem caused by the pressure, preventing it from bending due to continuous force, so that each cut can directly act on the hard stem. At the same time, this rhythmic contact can reduce the continuous impact of the hard stem on the pressure plate 23, reduce component wear, and extend the equipment life.

[0034] For hay that enters in bundles, this cyclical rhythm allows the bundled hay to naturally unfold when it is loosened, preventing the inner layer of hay from being wrapped by the outer layer due to continuous compression and thus preventing it from contacting the cutting mechanism 11. This ensures that the entire bundle of hay is cut evenly, improving the overall processing uniformity.

[0035] like Figures 1 to 6 and Figure 8 As shown: A support frame 22 is provided on the mounting frame 21. Multiple guide rods 221 extending in the horizontal direction are provided on the support frame 22. The guide rods 221 are sleeved on the mounting frame 21 and slide in cooperation with the mounting frame 21. A threaded rod 222 that is threaded in cooperation with the mounting frame 21 is provided in the center of the support frame 22. The threaded rod 222 and the guide rods 221 are parallel to each other.

[0036] The support frame 22 on the mounting bracket 21 forms a sliding engagement with the mounting bracket 21 via the guide rod 221. When the threaded rod 222 is rotated, since the threaded rod 222 is threaded into the mounting bracket 21 and parallel to the guide rod 221, the rotation of the threaded rod 222 is converted into the horizontal sliding of the support frame 22 along the guide rod 221, thereby driving the pressure plate 23 connected to the support frame 22 to move synchronously, realizing the adjustment of the relative position of the pressure plate 23 and the mounting bracket 21. During this process, multiple guide rods 221 extend horizontally and slide in engagement with the mounting bracket 21, providing stable guidance for the movement of the support frame 22, preventing it from deviating or tilting during sliding, and ensuring that the adjustment direction of the pressure plate 23 is precise and controllable.

[0037] The aforementioned structure allows the position of the pressing plates 23 to be flexibly adjusted according to the characteristics of the forage. When processing coarser or harder forage, the initial distance between the pressing plates 23 can be increased by rotating the threaded rod 222 to prevent jamming during feeding. When processing finer or softer forage, the distance can be reduced to enhance the clamping effect and improve adaptability. Simultaneously, the threaded rod 222 has a self-locking characteristic, ensuring that the position of the support frame 22 is securely locked after adjustment, preventing the pressing plates 23 from shifting due to vibration during operation and guaranteeing pressing stability. Furthermore, the multiple guide rods 221 further ensure the smoothness of the adjustment process, reduce component wear, and extend the equipment's service life.

[0038] like Figures 1 to 6 and Figure 8 As shown: The top of the support frame 22 is provided with a support shaft 223 extending in the horizontal direction. The top of the pressure plate 23 is rotatably connected to the support shaft 223. An elastic element 224 is provided between the bottom of the support frame 22 and the pressure plate 23, so that the pressure plate 23 is set on the support frame 22 in an inclined position.

[0039] When the pressing mechanism 2 is working, the support shaft 223 at the top of the support frame 22 provides a horizontal rotation fulcrum for the pressing plate 23. The top of the pressing plate 23 rotates around the support shaft 223. In the natural state of the bottom elastic element 224, the pressing plate 23 is tilted and forms an angle with the support frame 22, facilitating the entry of hay into the clamping channel formed between the two mounting frames 21. When the pressing plate 23 contacts the hay and is compressed, the reaction force of the hay pushes the pressing plate 23 to rotate towards the support frame 22. At this time, the bottom elastic element 224 is compressed. As the pressing plate 23 rotates, the angle between it and the support frame 22 gradually decreases, tending to be parallel. When the thickness of the hay decreases or the pressure decreases, the restoring force of the elastic element 224 pushes the pressing plate 23 to rotate in the opposite direction, restoring the tilted posture. This dynamic adjustment allows the pressing plate 23 to flexibly change its tilt angle according to the actual thickness of the hay, always maintaining effective contact with the hay.

[0040] Through the above structure, in the initial state, the inclined posture of the two pressing plates 23 provides ample space for different amounts of forage to enter, avoiding congestion during feeding. When compressed, the pressing plates 23 rotate toward the support frame 22 and compress the elastic element 224. This allows the clamping force to be adaptively adjusted by the elastic force of the elastic element 224, ensuring stable clamping of forage of different thicknesses. Furthermore, the clamping channel is gradually tightened through the narrowing angle, enhancing the guiding effect on the forage and assisting its transport to the cutting mechanism 11. Simultaneously, the movement trajectory of the pressing plates 23 tending to be parallel to the support frame 22 reduces excessive compression of the forage. Combined with the buffering effect of the elastic element 224, this prevents impact damage to the pressing plates 23 from hard-stemmed forage, improving the equipment's adaptability to various forage types and operational stability.

[0041] like Figures 1 to 6 and Figure 8 As shown: Two vertically extending slide rails 231 are provided on one end of the pressure plate near the support frame 22. A slider 2311 is provided on the slide rail 231 and slides therewith. The elastic element 224 is a telescopic elastic rod 2241. One end of the elastic rod 2241 is connected to the bottom of the support frame 22, and the other end of the elastic rod 2241 is hinged to the slider 2311.

[0042] When the pressure plate 23 rotates around the support shaft 223 toward the support frame 22, the pressure plate 23 drives the slide rail 231 to move synchronously, and the slider 2311 slides vertically along the slide rail 231. At this time, the elastic rod 2241 is stretched or compressed with the movement of the slider 2311, generating an elastic restoring force. When the pressure plate 23 rotates in the opposite direction due to the restoring force of the elastic rod 2241, the slider 2311 slides in the opposite direction along the slide rail 231, and the elastic rod 2241 gradually returns to its natural state. In this structure, the cooperation between the slide rail 231 and the slider 2311 provides directional guidance for the extension and retraction of the elastic rod 2241, ensuring that the force of the elastic rod 2241 is always transmitted in the preset direction, and avoiding the tilting of the pressure plate 23 caused by the force deviation of the elastic rod 2241. This makes the extension and retraction of the elastic rod 2241 more stable, the transmission of elastic force more direct, and allows for precise coordination with the rotation adjustment of the pressing plate 23. When processing thick, hard hay, the elastic rod 2241 is significantly compressed, and the elastic force is concentrated on the pressing plate 23 through the guiding action of the slider 2311 and the slide rail 231, enhancing the clamping force. When processing thinner hay, the elastic rod 2241 smoothly returns to its original position, pushing the pressing plate 23 to maintain contact and avoiding sudden changes in force. At the same time, the setting of the two slide rails 231 and the two sliders 2311 ensures the stability of sliding, reduces the shaking of the pressing plate 23 during rotation, ensures a uniform distribution of clamping force on the hay, further enhances the adaptability of the pressing mechanism 2 to hay with different characteristics, and extends the service life of the elastic rod 2241.

[0043] like Figures 2 to 5 , Figure 7 and Figure 8 As shown: the side of the pressure plate 23 away from the support frame 22 has a stepped structure, and the pressure plate 23 is provided with multiple rectangular protrusions 232 arranged in a row.

[0044] As the pressing plate 23 swings with the mounting frame 21 and presses the hay, the stepped structure creates staggered contact areas on the working surface of the pressing plate 23. The raised stepped surfaces directly press against the hay, while the depressions between the steps provide a deformation buffer space for the hay. Simultaneously, the rectangular array of protrusions 232 on each stepped surface enhances friction through microscopic multi-point contact, preventing hay slippage. The edges of the steps form lateral limiting, similar to tooth meshing, constraining the lateral movement of the hay and ensuring its orderly delivery to the cutting mechanism 11. When the hay thickness is uneven, the stepped structure can adapt to local protrusions, and the protrusions 232 disperse pressure through multi-point contact with the hay surface, making the clamping force more uniform.

[0045] The stepped structure provides progressive clamping guidance for forage of varying thicknesses, reducing the tendency of hard-stemmed forage to bounce under pressure. Meanwhile, the rectangular array of protrusions 232 further enhances control over soft or smooth forage by increasing the coefficient of friction. The combined effect of these two elements ensures that the pressure plate 23 maintains stable constraint on the forage throughout the clamping and releasing cycle. Furthermore, the combination of the stepped structure and protrusions 232 reduces the contact area between the pressure plate 23 and the forage, minimizing forage adhesion caused by excessive compression. Combined with the cushioning effect of the elastic element 224, this makes the mechanism more adaptable to various types of forage and ensures a smoother cutting process.

[0046] like Figures 2 to 4 and Figure 9 As shown: The cutting mechanism 11 includes two cutting rollers 111 that can rotate relative to each other, and each of the two cutting rollers 111 is provided with a plurality of cutting blades 1111 that are equidistantly arranged around its axis.

[0047] When the cutting mechanism 11 is running, the two cutting rollers 111 rotate relative to each other, and the cutting blades 1111 on them move in a circular motion with the rollers. The forage is conveyed between the two cutting rollers 111 by the pressure plate 23. Under the shearing action generated by the circular motion of the cutting blades 1111 and the relative rotation of the two cutting rollers 111, the forage is sequentially cut by the equidistantly distributed cutting blades 1111. The equidistant arrangement of the cutting blades 1111 ensures that the cutting spacing of the forage is uniform in the circumference of the rollers, guaranteeing a regular cut length. Simultaneously, when the two rollers rotate relative to each other, the movement trajectories of the cutting blades 1111 intersect, achieving not only continuous cutting of the forage but also breaking down the forage fibers through the relative compression and shearing of the cutting blades 1111, improving the cutting effect. This roller cutting structure, with the power of relative rotation and the synergy of the equidistant blades, can stably clamp and cut forage of different shapes, such as hard stems and soft grass, while avoiding jamming due to continuous circular motion, ensuring processing efficiency and quality.

[0048] like Figures 2 to 4 , Figure 10 and Figure 11As shown: The bottom of the frame 1 is located below the cutting mechanism 11 and has a semi-circular cavity 13. Multiple through holes 131 are evenly distributed on the outer edge of the semi-circular cavity 13. The cavity 13 is equipped with a kneading and cutting mechanism 14. A funnel-shaped material guide channel 12 is provided between the cavity 13 and the frame 1.

[0049] After being cut by the cutting mechanism 11, the hay enters the funnel-shaped feed channel 12 under gravity. The funnel shape of the channel allows the dispersed hay to naturally converge towards the center, preventing hay from piling up at the entrance of the cavity 13 and ensuring that the hay enters the semi-circular cavity 13 in an orderly manner. After entering the cavity 13, the hay is further processed by the shredding mechanism 14. The inner wall of the semi-circular cavity 13 provides guidance for the circular motion of the hay, allowing it to flow along the inner wall of the cavity 13 under centrifugal force, increasing the contact opportunity with the shredding mechanism 14. At the same time, the arc-shaped structure of the cavity 13 restricts the hay from spreading outward, allowing the hay to concentrate in the shredding area for thorough processing. When the hay is shredded to the required particle size, it is thrown to the outer edge of the cavity 13 under centrifugal force and discharged through the evenly distributed through holes 131; hay that does not meet the requirements continues to circulate in the cavity 13 until it is discharged through the through holes 131. The funnel-shaped feed channel 12 between the cavity 13 and the frame 1 not only guides the hay into the cavity 13, but also reduces splashing during the falling of the hay, preventing hay from adhering to the frame 1 and causing waste or cleaning burden. The semi-circular cavity 13 is adapted to the rotation trajectory of the shredding mechanism 14, making the whole process smoother, reducing material jamming or uneven processing caused by unreasonable structure, improving the shredding efficiency and effect of hay, and ensuring that the discharged hay particles are uniform in size to meet the needs of subsequent processing or use.

[0050] like Figures 2 to 4 , Figure 10 and Figure 11 As shown: The kneading and cutting mechanism 14 includes a rotating shaft 141 coaxially arranged with the axis of the cavity 13. The rotating shaft 141 is also provided with a plurality of partition plates 1411 equidistantly surrounding its axis. The end of the partition plate 1411 away from the rotating shaft 141 is provided with serrations.

[0051] The rotating shaft 141 of the shredding mechanism 14 is preferably driven by a rotary motor. When the rotating shaft 141 rotates, it drives multiple equidistant partition plates 1411 surrounding its axis to rotate synchronously. Since the rotating shaft 141 is coaxial with the semi-circular cavity 13, the rotation trajectory of the partition plates 1411 is adapted to the inner wall of the cavity 13, dividing the internal space of the cavity 13 into multiple independent processing zones. The serrations at the end of the partition plate 1411 away from the rotating shaft 141 rotate with the partition plate 1411. When they come into contact with the hay entering the cavity 13, they comb and separate clumps or tangled hay, while the edges of the serrations perform preliminary cutting on the thicker hay stems. During rotation, the partition plates 1411 guide the hay towards the edge of the cavity 13 through their own thrust, so that the hay in each zone is evenly distributed, avoiding accumulation near the rotating shaft 141, and ensuring that each part of the hay can fully contact the subsequent shredding components.

[0052] The cavity 13 is divided into multiple independent sections by multiple partition plates 1411, which effectively prevents the hay from tangling with each other in different areas, reducing insufficient cutting or equipment jamming caused by tangling. The serrations at the ends of the partition plates 1411 assist in cutting while combing the hay, which not only refines the initial shape of the hay, but also lays the foundation for deeper cutting in the future. The synchronously rotating partition plates 1411 continuously push the hay to the edge of the cavity 13. Combined with the arc-shaped structure of the cavity 13, the hay forms a stable circular motion trajectory inside the cavity 13, which increases the contact frequency and uniformity between the hay and the cutting components, thereby ensuring the consistency of the cutting effect. At the same time, it reduces the situation of insufficient local hay processing and enhances the stability of the mechanism operation.

[0053] like Figures 2 to 4 , Figure 10 and Figure 11 As shown: The kneading and cutting mechanism 14 also includes two saw blades 1412 sleeved on the rotating shaft 141. Between the two saw blades 1412, there are multiple mounting shafts 1413 parallel to the axis of the rotating shaft 141. The number of mounting shafts 1413 is the same as the number of partition plates 1411 and corresponds one-to-one. Each mounting shaft 1413 is provided with multiple equidistant blades 1414 along its axis. The blades 1414 are rotatably mounted on the mounting shaft 1413 and are provided with saw teeth.

[0054] When the rotating shaft 141 drives the saw blades 1412 to rotate synchronously, the two saw blades 1412 cut the forage entering the cavity 13, thereby further chopping the larger pieces of grass. Since the number of mounting shafts 1413 and the partition plates 1411 are the same and correspond one-to-one, the mounting shafts 1413 rotate synchronously within the independent area formed by the partition plates 1411. The slashing blades 1414 on the mounting shafts 1413 open outward under the action of centrifugal force and move in a circular motion with the mounting shafts 1413. When they come into contact with the forage, the saw teeth on the slashing blades 1414 strike and cut the forage. At the same time, the slashing blades 1414 can rotate around the mounting shafts 1413. When encountering harder grass stems or greater resistance, the slashing blades 1414 will adaptively swing around the mounting shafts 1413 to adjust the angle of force and enhance the ability to crush forage of different hardness. As the hay moves towards the edge of the cavity 13 along with the separator 1411, the saw blade 1412 and the swivel cutter 1414 alternately act on the hay. The continuous rotation of the saw blade 1412 provides a stable cutting force, while the swivel of the swivel cutter 1414 produces random striking and tearing effects. Together, they further refine the hay. When the hay is broken down to a sufficiently small size, it is discharged through the through-hole 131 at the edge of the cavity 13.

[0055] The synergistic crushing effect of the saw blade 1412 and the swivel cutter 1414 through cutting and impact enhances the processing capacity for forage of different shapes and hardness. The corresponding setting of the mounting shaft 1413 and the partition plate 1411 ensures that the forage can be completely crushed in each independent section, ensuring that the forage is fully processed in each section and avoiding uneven processing in some areas. The rotatable swivel cutter 1414 allows it to swing adaptively, enhancing the crushing capacity for stubborn fibers and extending the service life of the equipment. The equidistant arrangement of the swivel cutter 1414 and the saw blade 1412 ensures that the forage is uniformly processed in both the axial and circumferential directions, guaranteeing the consistency of the output particle size and improving the crushing quality and efficiency.

[0056] A forage processing apparatus includes a flexible pressing forage cutting mechanism as described above.
