Description

Technical Field

[0001] This invention belongs to the technical field of forage processing, and more specifically, relates to a forage processing system. Background Technology

[0002] Forage is a major component of livestock feed. Since fresh forage is difficult to store, it needs to be dried or oven-dried before storage for later use. However, because harvested forage is indivisible, drying or sun-drying requires considerable space to prevent it from scattering. Furthermore, the collection and storage of dehydrated forage necessitates additional sorting to prevent further scattering and reduce the efficiency of the subsequent pulverizing process in feed preparation. Therefore, there is an urgent need for a forage processing system that can connect forage in an orderly manner to form a continuous mat, enabling continuous processing. Moreover, by indenting the mat, sufficient space can be provided for air passage after rolling, improving the drying or sun-drying efficiency of the forage and effectively saving drying and storage space while reducing workload. Summary of the Invention

[0003] This invention provides a forage processing system for orderly connecting forage together to form a continuous straw mat, thereby enabling continuous processing of the straw mat; moreover, by indenting the straw mat, the rolled-up straw mat has sufficient space for gas to pass through, improving the drying or air-drying efficiency of the forage, and effectively saving drying and storage space and reducing labor intensity.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A forage processing system includes a curved indentation mechanism, a winding and drying mechanism, a roller pressing and shaping mechanism, and an adjustable cutting mechanism arranged sequentially along the processing direction of the forage. The forage is arranged laterally and sewn into a straw mat by a straw weaving machine. The curved indentation mechanism has indentation rollers, and the straw mat is rolled by the indentation rollers to form curved indentations. The rolled straw mat is wound into the winding and drying mechanism, and the dried straw mat roll is pulled out from the middle and supplied to the roller pressing and shaping mechanism in a spiral shape. The flat straw mat after being rolled and shaped by the roller pressing and shaping mechanism enters the adjustable cutting mechanism and is cut and crushed by the adjustable cutting mechanism.

[0006] Furthermore, the roll forming mechanism includes a roll pressing pusher pair mounted on the mounting base, and the indentation pair is located at the exit end of the roll pressing pusher pair and is mounted on the mounting base.

[0007] Furthermore, the indentation rollers include an upper indentation roller and a lower indentation roller arranged sequentially in a vertical direction. Multiple indentation grooves and multiple indentation protrusions are respectively constructed on the circumferential surfaces of the upper and lower indentation rollers. When the indentation rollers roll the straw mat, the indentation protrusions extend into the corresponding indentation grooves. The indentation grooves are curved closed-loop grooves formed along the circumference of the upper indentation roller, and the indentation protrusions are curved closed-loop protrusions formed along the circumference of the lower indentation roller. Alternatively, the indentation grooves are spiral grooves extending spirally along the axis of the upper indentation roller, and the spiral grooves are formed on the circumferential surface of the upper indentation roller. The indentation protrusions are spiral protrusions extending spirally along the axis of the lower indentation roller, and the spiral protrusions are formed on the circumferential surface of the lower indentation roller.

[0008] Furthermore, the winding and drying mechanism includes a bottom fixed base set on the ground, the bottom fixed base being fixedly connected to a support base via multiple connecting rods, a material cage being detachably connected to the support base, and a vertical winding shaft being rotatably mounted on the bottom fixed base. The vertical winding shaft passes through the support base and extends into the material cage, the vertical winding shaft being rotatably connected to the support base, and the axis of the vertical winding shaft coinciding with that of the material cage.

[0009] Furthermore, a guide cover is rotatably connected to the upper end of the material cage. The diameter of the guide cover gradually narrows upward in the vertical direction, and the large diameter end of the guide cover is rotatably connected to the upper end of the material cage. The small diameter end of the guide cover is equipped with an outlet nozzle. Multiple spiral protrusions are constructed on the inner wall of the guide cover, and a swirling channel is formed between adjacent spiral protrusions. Multiple guide ports are spaced apart on the support base.

[0010] Furthermore, the roller pressing and shaping mechanism includes multiple roller pressing and shaping pairs installed inside the machine housing. These roller pressing and shaping pairs are spaced apart in the direction of hay conveying, and the roller pressing gap between the roller pressing and shaping pairs decreases along the direction of hay conveying. A guide roller is rotatably installed at the inlet end of the machine housing.

[0011] Furthermore, the roll forming rollers include an upper forming roller and a lower forming roller arranged vertically at intervals. The roll forming gap is formed between the upper forming roller and the lower forming roller. Connecting shafts are fixed at both ends of the axial direction of the upper forming roller and the axial direction of the lower forming roller, respectively. Sliding blocks are rotatably connected to each of the connecting shafts. The sliding blocks are slidably connected to the side wall of the machine housing. Adjusting rods are rotatably connected to the sliding blocks. The adjusting rods extend vertically out of the machine housing. Locking nuts are threaded onto the adjusting rods and locked onto the corresponding end faces of the machine housing.

[0012] Furthermore, the adjustable cutting mechanism includes two cutting rollers installed vertically at intervals inside the assembly housing, a feed hood is installed at the inlet end of the assembly housing, the feed hood is connected to the outlet of the roller forming rollers, and a discharge cylinder is installed at the outlet end of the assembly housing.

[0013] Furthermore, the cutting roller includes a shaft coaxially disposed within the cylindrical roller body, and strip-shaped openings are uniformly formed around the circumference of the cylindrical roller body. Each strip-shaped opening extends from one end of the cylindrical roller body to the other end axially. A cutting blade is assembled within each strip-shaped opening. The cutting blade extends radially out of the cylindrical roller body. The two ends of the portion of the cutting blade located within the cylindrical roller body are connected to the two ends of the shaft via two adjusting components. The shaft is rotatably connected to the mounting shell.

[0014] Furthermore, the cutting blade includes multiple first blade bodies and second blade bodies, which are alternately arranged circumferentially along the cylindrical blade roller body; the adjusting assembly includes a first adjusting sleeve and a second adjusting sleeve fitted on the shaft, and multiple first hinge rods and second hinge rods are respectively hinged to the first adjusting sleeve and the second adjusting sleeve. The end of the first hinge rod away from the first adjusting sleeve is hinged to the corresponding first blade body, and the end of the second hinge rod away from the second adjusting sleeve is hinged to the corresponding second blade body.

[0015] The present invention, by employing the aforementioned structure, achieves a technological advancement compared to existing technologies in the following ways: The present invention uses a straw weaving machine to connect the middle and sides of side-by-side forage grasses to form a straw mat. Specifically, the weaving machine uses straw ropes to connect the middle and sides of the forage grasses. The thickness of the straw mat depends on the layer thickness of the forage grasses; generally, the layer thickness of fresh forage grasses is 6-10 cm. Then, a curved indentation mechanism continuously rolls the straw mat, creating curved indentations and giving the mat an undulating, wave-shaped surface. Because fresh straw mats have a certain degree of toughness, they will not break after being rolled by the curved indentation mechanism. Next, the wave-shaped straw mat is rolled up by a winding and drying mechanism, maintaining a loose, rolled shape. Due to the shape limitation of the wave-shaped straw mat, each layer of the rolled-up straw mat has sufficient gaps for air circulation, ensuring efficient drying or air-drying of the straw mat roll. On the other hand, it reduces space occupancy, and the straw mat roll improves transfer efficiency, eliminating the need for additional personnel to sort the forage. In the later feed preparation, only the middle part of the straw mat roll needs to be pulled out, forming a spiral curl. This spiral curl enters the roller pressing and shaping rollers, which gradually flatten it, preventing the fluffy spiral curl from entering the adjustable cutting mechanism and reducing the cutting and crushing efficiency. By adjusting the adjustable cutting mechanism, the forage is cut into small segments within a predetermined length range. In summary, this invention connects fresh forage in an orderly manner to form a continuous straw mat, thereby enabling continuous processing of the straw mat. Moreover, the indentation process of the straw mat allows sufficient space for gas to pass through after rolling, improving the drying or air-drying efficiency of the forage, effectively saving drying and storage space, and reducing labor intensity.

Detailed Implementation

[0041] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.

[0042] This invention discloses a forage processing system, such as Figure 1-22As shown, the invention includes a curved indentation mechanism 100, a winding and drying mechanism 200, a roller pressing and shaping mechanism 300, and an adjustable cutting mechanism 400 arranged sequentially along the processing direction of the forage. The forage is arranged laterally and sewn into a straw mat 500 by a straw weaving machine. The curved indentation mechanism 100 of this invention has indentation rollers. The straw mat 500 is pressed by the indentation rollers to form curved indentations. The pressed straw mat 500 is then wound into the winding and drying mechanism 200. The dried straw mat roll 700 is pulled out from its middle and supplied in a spiral shape to the roller pressing and shaping mechanism 300. The flattened straw mat 500 after being pressed and shaped by the roller pressing and shaping mechanism 300 enters the adjustable cutting mechanism 400 and is cut and shredded by the adjustable cutting mechanism 400. The working principle and advantages of this invention are as follows: This invention uses a straw weaving machine to connect the middle and sides of side-by-side hay to form a straw mat 500. Specifically, the straw weaving machine uses straw ropes 900 to connect the middle and sides of the hay. The thickness of the straw mat 500 depends on the layer thickness of the hay; generally, the layer thickness of fresh hay is 6-10 cm. Then, a curved indentation mechanism 100 continuously rolls the straw mat 500, creating curved indentations on its surface, resulting in an undulating surface. The fresh straw mat 500 is then transformed into a corrugated straw mat 600. Because the fresh straw mat 500 has a certain degree of toughness, it will not break after being rolled by the curved indentation mechanism 100. Next, the corrugated straw mat 600 is rolled up by the winding and drying mechanism 200, and the rolled-up straw mat roll 700 maintains a loose, rolled shape. Due to the shape limitation of the corrugated straw mat 600, each layer of the rolled-up straw mat roll 700 has sufficient gaps for air circulation, ensuring the drying or air-drying efficiency of the straw mat roll 700 while reducing... With reduced space occupancy and improved transfer efficiency, the hay roll 700 eliminates the need for additional personnel to manage the hay. In later feed preparation, only the middle section of the hay roll 700 needs to be pulled out, forming a spiral curl 800. This spiral curl 800 enters the pressing and shaping rollers 302, which gradually flatten it, preventing the fluffy spiral curl 800 from entering the adjustable cutting mechanism 400 and reducing cutting and shredding efficiency. By adjusting the adjustable cutting mechanism 400, the forage is cut into small segments within a predetermined length range. In summary, the present invention connects fresh forage together in an orderly manner to form a continuous straw mat 500, thereby enabling continuous processing of the straw mat 500. Moreover, by indenting the straw mat 500, the rolled-up straw mat 500 has sufficient space for gas to pass through, improving the drying or air-drying efficiency of the forage, and effectively saving drying and storage space, and reducing labor intensity.

[0043] As a preferred embodiment of the present invention, such as Figure 2-5As shown, the roller pressing and shaping mechanism 300 includes a mounting base 101, roller pressing and pushing rollers 102, and indentation rollers. The roller pressing and pushing rollers 102 and the indentation rollers are installed at intervals on the mounting base 101 along the conveying direction of the straw mat 500, and the indentation rollers are located at the exit end of the roller pressing and pushing rollers 102. The roller pressing and pushing rollers 102 include an upper pushing roller and a lower pushing roller arranged at intervals along the vertical direction. First rotating shafts 103 are fixed at both axial ends of the upper pushing roller and the lower pushing roller, respectively. Each first rotating shaft 103 is rotatably connected to a corresponding side of the mounting base 101. In this embodiment, the indentation rollers include an upper indentation roller 104 and a lower indentation roller 106 arranged sequentially along the vertical direction. Second rotating shafts 108 are fixedly connected at both axial ends of the upper indentation roller 104 and the lower indentation roller 106, respectively. Each second rotating shaft 108 is rotatably connected to a corresponding side of the mounting base 101. Multiple indentation grooves are formed on the circumferential surface of the upper indentation roller 104, and multiple indentation protrusions are formed on the circumferential surface of the lower indentation roller 106. The number of indentation grooves and indentation protrusions are the same, and they are arranged in a one-to-one correspondence. When the indentation rollers roll the straw mat 500, the indentation protrusions extend into the corresponding indentation grooves. The combination of indentation grooves and indentation protrusions is of two types. In the first type, the indentation groove is a curved closed-loop groove 105 formed along the circumference of the upper indentation roller 104, and the indentation protrusion is a curved closed-loop protrusion 107 formed along the circumference of the lower indentation roller 106. The second type is a complete and continuous indentation groove and an indentation protrusion. The indentation groove is a spiral groove 109 that extends spirally along the axis of the upper indentation roller 104 and is formed on the circumferential surface of the upper indentation roller 104. The indentation protrusion is a spiral protrusion 110 that extends spirally along the axis of the lower indentation roller 106 and is formed on the circumferential surface of the lower indentation roller 106. The working principle and advantages of this embodiment are as follows: In this embodiment, the roller pressing and pushing roller 102 and the indentation roller are driven to operate. The roller pressing and pushing roller 102 rolls the straw mat 500 and continuously and stably pushes it to the indentation roller. The indentation roller, through the cooperation of the indentation groove and the indentation protrusion, rolls the straw mat 500 to form undulating protrusions and depressions, thereby ensuring that the straw mat roll 700 after being rolled up by the winding and drying mechanism 200 has sufficient gaps for air circulation, thus ensuring that the straw mat roll 700 is effectively dried or baked. Moreover, the grooves formed by the pressure of the indentation groove and the indentation protrusion have a special shape, so that the grooves and protrusions between adjacent inner and outer layers of the straw mat roll 700 are staggered, ensuring that the straw mat roll 700 is in a non-tight state, thus ensuring that the straw mat roll 700 has a good air guiding channel.

[0044] As a preferred embodiment of the present invention, such as Figure 6-11As shown, the winding and drying mechanism 200 includes a bottom fixing base 201, a support base 203, a material cage 206, and a vertical winding shaft 204. The material cage 206 includes multiple fixing rods, which are evenly arranged along the circumference of the support base 203 to form a cage-like structure. The upper end of each fixing rod extends inward and obliquely upward. A lower connecting ring 208 is provided at the lower end of the cage-like structure. The lower end of each fixing rod is fixedly connected to the lower connecting ring 208, and the upper end of the fixing rod is connected to an upper adapter ring 210. Furthermore, the axes of the upper adapter ring 210, the lower connecting ring 208, and the cage-like structure coincide. In this embodiment, multiple snap-fit ​​blocks 209 are evenly arranged circumferentially on the lower connecting ring 208, and snap-fit ​​interfaces 215 are evenly opened circumferentially on the outer edge of the support base 203. The snap-fit ​​blocks 209 are firmly snapped into the corresponding snap-fit ​​interfaces 215, and the lower connecting ring 208 is assembled on the support base 203, thereby realizing the detachable connection between the material cage 206 and the assembly base 101. In this embodiment, the bottom fixing base 201 is set on the ground. The bottom fixing base 201 is fixedly connected to the support base 203 through multiple connecting rods 202. The vertical winding shaft 204 is rotatably mounted on the bottom fixing base 201. The vertical winding shaft 204 passes through the support base 203 and extends into the material cage 206. The vertical winding shaft 204 is rotatably connected to the support base 203, and the axis of the vertical winding shaft 204 coincides with that of the material cage 206. In this embodiment, a first drive sprocket 205 is coaxially mounted on the vertical winding shaft 204. The first drive sprocket 205 is located between the bottom fixing seat 201 and the support seat 203. The first drive sprocket 205 is driven to drive the vertical winding shaft 204, thereby causing the corrugated straw mat 600, which has one end extending into the material cage 206 and connected to the vertical winding shaft 204, to be wound up inside the material cage 206. Moreover, when the straw mat roll 700 is finished being wound up, the material cage 206 can be removed, and then the straw mat roll 700 can be taken out for drying or baking. In this embodiment, the straw mat rolls 700 can also be naturally air-dried or forced-dried within the material cage 206. Specifically, a guide cover 207 is provided at the upper end of the material cage 206. The diameter of the guide cover 207 gradually narrows upwards in the vertical direction, and a connecting edge 211 coinciding with its axis is constructed at the large-diameter end of the guide cover 207. This connecting edge 211 is rotatably connected to the upper adapter ring 210, thereby achieving the purpose of rotatably connecting the guide cover 207 to the upper end of the material cage 206. In this embodiment, an outlet nozzle 212 is constructed at the small-diameter end of the guide cover 207, and multiple spiral protrusions 213 are constructed on the inner wall of the guide cover 207. A swirling channel 214 is formed between adjacent spiral protrusions 213, and multiple guide ports 216 are spaced apart on the support base 203.The working principle and advantages of this embodiment are as follows: When the straw mat roll 700 needs to be dried, hot air is introduced into the guide cover 207 through the outlet 212. Under the action of the swirling channel 214, the hot air swirls into the material cage 206 and gradually passes through various parts of the straw mat roll 700, and finally exits from the circumference of the straw mat roll 700 and the guide port 216 of the support base 203, thereby achieving the purpose of forced drying of the straw mat roll 700. In this embodiment, when the dried straw mat roll 700 is cut and crushed, the middle part of the straw mat roll 700 is pulled upward and pulled to the roller pressing and shaping mechanism 300 through the outlet 212 of the guide cover 207. At this time, the shape of the straw mat roll 700 is as shown. Figure 12 As shown in the diagram, the straw mat roll 700 is gradually unrolled from the inside to the outside within the material cage 206 as the roller pressing and shaping mechanism 300 pulls it through. During the unrolling process, the spiral curled part 800 is restricted by the conical shape of the guide cover 207 when it passes through the guide cover 207. Furthermore, friction is generated between the spiral protrusion 213 and the pulled spiral curled part 800, causing the guide cover 207 to rotate passively. As the guide cover 207 rotates, the radial length of the spiral curled part 800 gradually decreases until it becomes close to the diameter of the outlet nozzle 212. This ensures that the spiral curled part 800 can be smoothly pulled out of the guide cover 207 from the outlet nozzle 212. In this embodiment, to ensure that the spiral coiling part 800 maintains the predetermined spiral shape and to prevent it from unwinding in reverse, the guide cover 207 can be actively driven to rotate. This causes the guide cover 207 to rotate the spiral coiling part 800 by a predetermined angle, so that the pitch and other parameters of the spiral coiling part 800 are kept within a predetermined range. This facilitates the subsequent rolling and shaping by the roller pressing mechanism 300 and the cutting and crushing by the adjustable cutting mechanism 400.

[0045] As a preferred embodiment of the present invention, such as Figure 13 , 14As shown, the roller pressing and shaping mechanism 300 includes a housing 301 and multiple roller pressing and shaping pairs 302. These roller pressing and shaping pairs 302 are installed inside the housing 301, and are spaced apart in the direction of hay conveying. The roller gap 309 of the roller pressing and shaping pairs 302 decreases along the direction of hay conveying. A guide roller 303 is rotatably installed at the inlet end of the housing 301. The working principle and advantages of this embodiment are as follows: In this embodiment, the guide roller 303 guides the spiral curled part 800 from the winding and drying mechanism 200, so that the spiral curled part 800 smoothly enters the roller pressing and shaping mechanism 300. Since the hay in the dry state is relatively weak, it is not suitable to directly flatten it to the predetermined thickness in one go. That is, flattening it in one go will generate a lot of debris, which is not easy to collect and clean, and will pollute the surrounding environment. It is necessary to gradually press the spiral curled part 800 so that it is gradually flattened. In this way, the aforementioned multiple pressing and shaping rollers 302 press the spiral curled portion 800, and since the pressing gap 309 of these pressing and shaping rollers 302 decreases along the conveying direction of the forage, the spiral curled portion 800 is smoothly flattened to a predetermined thickness. The pressing and shaping rollers 302 in this embodiment include an upper pressing roller and a lower pressing roller arranged vertically at intervals, and the pressing gap 309 is formed between the upper pressing roller and the lower pressing roller. Connecting shafts 304 are fixed at both ends of the axial direction of the upper pressing roller and the lower pressing roller, respectively, and second transmission sprockets 305 are respectively installed on the connecting shafts 304 on the same side. In this embodiment, to facilitate adjustment of the distance between the upper and lower forming rollers and thus achieve the purpose of adjusting the roller gap 309, the following measures are taken: a sliding block 306 is rotatably connected to each connecting shaft 304. The sliding block 306 is slidably connected to the side wall of the housing 301. An adjusting rod 307 is rotatably connected to the sliding block 306, extending vertically out of the housing 301. A locking nut 308 is threaded onto the adjusting rod 307, locking it to the corresponding end face of the housing 301. The working principle and advantages of this embodiment are: when it is necessary to adjust the roller gap 309, the corresponding locking nut 308 is loosened, and the adjusting rod 307 is adjusted, causing the sliding block 306 to move vertically, thereby adjusting the roller gap 309. After adjustment, the locking nut 308 is tightened. This ensures a smooth transition of the spiral coiled portion 800 and prevents the generation of a large amount of debris during roller pressing.

[0046] As a preferred embodiment of the present invention, such as Figure 15-21As shown, the adjustable cutting mechanism 400 includes an assembly housing 401, a feed hood 403, a discharge cylinder 404, and two cutting rollers. These two cutting rollers are vertically spaced within the assembly housing 401. Lateral connecting plates 402 are installed on both sides of the assembly housing 401, and the axial ends of the cutting rollers are rotatably connected to the corresponding lateral connecting plates 402. In this embodiment, the feed hood 403 is installed at the inlet end of the assembly housing 401 and communicates with the outlet of the roll forming roller 302. The discharge cylinder 404 is installed at the outlet end of the assembly housing 401. The rolled spiral curled portion 800 enters the assembly housing 401 through the outlet of the roll forming roller 302, is then cut into segments by the relatively rotating cutting rollers, and finally discharged through the discharge cylinder 404. The specific structure of the cutting roller in this embodiment is as follows: the cutting roller includes a cylindrical roller body 405, a shaft 407, and multiple cutting blades. The shaft 407 is coaxially mounted inside the cylindrical cutter roller body 405. Strip-shaped openings 406 are evenly distributed circumferentially on the cylindrical cutter roller body 405, each extending axially from one end to the other. Each cutting blade is mounted on a corresponding strip-shaped opening 406, extending radially out of the cylindrical cutter roller body 405. The two ends of the cutting blade located inside the cylindrical cutter roller body 405 are connected to two adjusting components, which are respectively connected to the two ends of the shaft 407. The shaft 407 is rotatably connected to a corresponding lateral connecting plate 402. A third transmission sprocket 408 is mounted on the shaft 407 on the same side. Driving the third transmission sprocket 408 drives the two cutting rollers to rotate relative to each other, thus cutting the material into segments. The multiple cutting blades described in this embodiment include an equal number of first blade bodies 413 and multiple second blade bodies 414, which are alternately arranged circumferentially along the cylindrical cutter roller body 405. The adjustment assembly includes a first adjustment sleeve 409 and a second adjustment sleeve 410 mounted on a shaft 407. Multiple first hinge rods 411 are hinged to the first adjustment sleeve 409, with the end of each first hinge rod 411 away from the first adjustment sleeve 409 hinged to a corresponding first blade body 413. Multiple second hinge rods 412 are hinged to the second adjustment sleeve 410, with the end of each second hinge rod 412 away from the second adjustment sleeve 410 hinged to a corresponding second blade body 414.The working principle and advantages of this embodiment are as follows: This embodiment can adjust the position of the first adjusting sleeve 409 and / or the first adjusting sleeve 409 on the adjusting component according to the needs, so that the first hinge rod 411 and / or the second hinge rod 412 drive the first cutter body 413 and / or the second cutter body 414 to move radially along the cylindrical cutter roller body 405, so that the first cutter body 413 and / or the second cutter body 414 extend out of the cylindrical cutter roller body 405 at different lengths, thereby realizing the cutting of the flat spiral curled part 800 into segments of different lengths. It can also realize the intermittent cutting of the flat spiral curled part 800 at different depths, so that the proportion of pasture segments of different lengths reaches the expected level. Specifically, the lengths of the first cutter body 413 and / or the second cutter body 414 extending beyond the cylindrical cutter roller body 405 are adjusted. Taking the example that the first cutter body 413 can completely cut through the flat spiral curled portion 800, the extension length of the second cutter body 414 is adjusted so that the second cutter body 414 cuts into the flat spiral curled portion 800 to a predetermined depth. At this point, the second cutter body 414 does not completely cut through the spiral curled portion 800. In this way, two adjacent first cutters 413 are cut into a complete segment (long segment). At this complete segment, a second cutter body 414 cuts into the complete segment to a predetermined depth, resulting in multiple short segments on this complete segment. Therefore, the ratio of long segments to short segments can be adjusted by adjusting the extension length of the second cutter body 414, thereby enabling the preparation of different types of livestock feed.
