Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology. More specifically, this utility model relates to a creeping type grass cutting machine. Background Technology

[0002] A forage mower is an important piece of machinery used in agricultural production for harvesting forage. Through mechanized operation, it can significantly improve the efficiency and quality of forage harvesting. A traditional reciprocating mower typically consists of a main component including an engine, transmission, drive shaft, reciprocating power head, and cutter, as well as auxiliary equipment such as handles, throttle, and control switches. The working principle of a reciprocating mower is based on a reciprocating power head. The engine outputs power, which is transmitted to the reciprocating power head through the transmission and drive shaft. The power head generates reciprocating motion, which in turn drives the cutter to cut the grass. When the blades on the cutter come into contact with the lawn, they quickly cut the grass, leaving neat and aesthetically pleasing cuts. Reciprocating mowers are equipped with wheels or tracks, such as a four-wheeled tractor, to propel them forward, allowing the entire mower to move across the ground and cover the entire mowing area.

[0003] However, while traditional forage cutters perform well in most forage harvesting scenarios, they face significant challenges when harvesting forage that lies prostrate on the ground. This is especially true when harvesting species like purslane, whose stems typically lie prostrate on the ground rather than growing upright, making it difficult for traditional mowers to effectively cut them and resulting in low seed yields.

[0004] Gardenia jasminoides, a valuable forage grass, has seeds rich in nutrients and is an important feed source for livestock. However, its stems lie prostrate on the ground, making it difficult for traditional forage cutters to reach them effectively. Even when the blades do reach the ground, the uneven surface and the flexibility of the stems often result in poor cutting, leaving large amounts of stems and seeds uncollected and unusable, increasing the difficulty of subsequent processing and cleanup.

[0005] Furthermore, because the stems of the cowberry creep along the ground, traditional forage cutters are prone to clogging and tangling during harvesting. This not only affects harvesting efficiency but can also lead to machine malfunctions and increase harvesting costs.

[0006] Therefore, a specialized harvester needs to be designed for gardenia, a type of forage grass whose stems creep along the ground, to solve the problem that traditional forage harvesters cannot effectively harvest it and to improve the harvest rate of gardenia seeds. Utility Model Content

[0007] One object of this invention is to solve at least the problems described above and to provide at least the advantages that will be explained later.

[0008] To achieve these objectives and other advantages according to this utility model, a creeping type of barnyard grass cutter is provided, comprising:

[0033] This utility model has at least the following beneficial effects:

[0034] First, this utility model's creeping forage cutter achieves rapid, efficient, and stable cutting of forage through the use of multiple lifting rods and a specific structural design. The front end of the lifting rod is tilted downwards and forwards at a suitable angle, allowing it to better insert into the forage and lift it off the ground, while reducing resistance during the cutting process. The rear end forms a smooth and continuous arc structure, guiding the forage steadily towards the cutter blades, reducing forage loss and waste during the cutting process.

[0035] Secondly, the creeping forage cutter of this utility model significantly enhances its mobility and stability by adding a pair of support bases and swivel wheels. The support bases provide solid support for the cutter, ensuring that the cutter is not prone to tipping over or shaking during operation, thus guaranteeing cutting accuracy and safety. The swivel wheels allow the cutter to easily handle various terrains and ground conditions, enabling smooth and rapid movement on flat grasslands or rugged slopes, greatly improving the efficiency and flexibility of cutting operations.

[0036] Third, the side-cutting blade can cut the branches of the grass on both sides of the harvester's path, effectively separating the cut grass from the uncut grass and avoiding areas that may be missed by traditional harvesters. At the same time, the blade of the side-cutting blade is tilted downward and forward at a suitable angle, reducing resistance during the cutting process and improving cutting efficiency.

[0037] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0047] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0048] It should be noted that, unless otherwise specified, the experimental methods described in the following embodiments are all conventional methods, and the reagents and materials described are all commercially available unless otherwise specified. In the description of this utility model, the orientation or positional relationship indicated by the terms is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description. It does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0049] like Figures 1-8 As shown, this utility model provides a creeping type of cowberry forage cutter, comprising:

[0050] The reciprocating lawnmower body is equipped with a cutter 1 and a drive device that drives the cutter 1 to reciprocate.

[0051] Multiple drafting rods 2 are spaced apart on the cutter 1;

[0052] The front end of each drafting rod 2 is tilted downward and forward at a suitable angle.

[0053] The rear end of the drafting rod 2 gradually arches upward from the front end to the rear end of the blade of the cutter 1, forming a smooth and continuous arc-shaped structure.

[0054] The two adjacent starting rods are set at an appropriate distance.

[0055] In the above technical solution, the creeping forage mower of this utility model mainly includes a reciprocating mower body. This reciprocating mower body is the core part of the mower, responsible for providing power and supporting other components. A cutter 1 is mounted on the reciprocating mower body, which is the main tool for cutting forage. In addition, there is a drive unit that provides power for the reciprocating motion of the cutter 1, enabling the cutter 1 to continuously cut forage.

[0056] Multiple shovels 2 are designed on the cutter 1. These shovels 2 are distributed at intervals on the cutter 1, and their main function is to help lift the hay from the ground and guide it to the blades of the cutter 1 for cutting. The number and distribution of the shovels 2 can be adjusted according to actual needs to ensure optimal cutting results.

[0057] The front end of each drafting rod 2 is angled downwards and forwards at a suitable angle. This angle is designed to allow the drafting rod 2 to better insert into the hay and lift it off the ground. At the same time, this angle also helps reduce the resistance encountered by the drafting rod 2 during cutting, improving cutting efficiency.

[0058] The rear end of the shovel 2 arches upwards from the front to the rear of the cutter 1 blade, forming a smooth and continuous arc shape. This arc shape is designed to allow the shovel 2 to better guide the hay to the cutter 1 blade and ensure a stable flow of hay during cutting. Furthermore, this arc shape helps reduce hay loss and waste during the cutting process.

[0059] An appropriate spacing is maintained between adjacent hobbing rods 2. This spacing ensures that the hay can pass smoothly through the space between the hobbing rods 2 and be effectively cut by the cutter 1. Simultaneously, this spacing prevents excessive crowding and friction between the hobbing rods 2, improving the overall performance and durability of the cutter. Furthermore, this spacing also ensures that all hay is effectively lifted from the ground, preventing any spillage.

[0060] In practical applications, the angle, number, and spacing of the cutting rods 2 can be adjusted according to factors such as the height and density of the forage and ground conditions to achieve the best cutting effect. Furthermore, the power and speed of the drive unit can be adjusted to adapt to different working environments and cutting needs.

[0061] In summary, this creeping forage cutter achieves rapid, efficient, and stable cutting of forage through the use of multiple curved cutting rods 2 and a specific structural design. Furthermore, the cutter boasts advantages such as simple structure, convenient operation, and high durability, making it widely applicable to various pastures and grasslands.

[0062] In another technical solution, a pair of support bases 3 are also included. The pair of support bases 3 are arranged opposite to each other and are fixed to the bottom of the mounting base 11 of the cutter 1. The support bases 3 are provided with casters 31.

[0063] In the above technical solution, the creeping forage cutter of this utility model also includes a pair of support bases 3. These support bases 3 are arranged opposite to each other and are fixedly supported at the bottom of the mounting base 11 of the cutter 1. The main function of the support bases 3 is to provide additional stability and support, ensuring that the cutter remains stable during the cutting process and is not easily tipped over or shaken.

[0064] Casters 31 are installed on the support base 3. These casters 31 allow the mower to move easily on the grass, facilitating cutting operations. The design of the casters 31 also helps the mower adapt to different terrains and ground conditions, improving the flexibility and efficiency of cutting operations.

[0065] In another technical solution, mounting plates 4 are further provided on both sides of the mounting base 11, and a side cutting blade 41 is fixed on the mounting plate 4. The blade of the side cutting blade 41 is tilted downward and forward at a suitable angle.

[0066] In the above technical solution, these mounting plates 4 are tightly connected to the mounting base 11 by bolts or other secure fixing methods, ensuring their stability and reliability during operation.

[0067] The side-cutting blade 41 is carefully installed on the mounting plate 4. The side-cutting blade 41 is meticulously designed, with its blade angled downwards and forwards at an appropriate angle. This angle was determined through precise calculations and numerous experiments to ensure that the side-cutting blade 41 can effectively cut the cowrie branches on both sides of the lawnmower. At the same time, this angle also helps to reduce resistance during the cutting process and improve cutting efficiency.

[0068] The main function of the side cutting blade 41 is to cut the grass branches on both sides of the mower's path, thereby separating the cut grass from the uncut grass. This helps improve the mower's cutting efficiency.

[0069] In the specific implementation process, the following points should also be noted:

[0070] The blade of the side cutter 41 should be kept sharp to ensure it can effectively cut through the branches of the cowberry. During use, the wear of the blade needs to be checked regularly, and it should be replaced or sharpened in a timely manner.

[0071] The installation position and tilt angle of the side cutting blade 41 need to be adjusted according to the actual situation. For example, when the grass density is high or the branches of the cowberry are thick, the tilt angle of the cutting blade can be appropriately reduced to increase the cutting force; while when the grass is sparse or the ground is uneven, the tilt angle of the cutting blade can be appropriately increased to reduce the resistance during the cutting process.

[0072] In summary, by setting mounting plates 4 on both sides of the mounting base 11 and fixing the side cutting blades 41, the functionality and practicality of the creeping cattle branch grass cutter are further enhanced.

[0073] In another technical solution, fixing plates 5 are further provided on both sides of the mounting base 11, and fixing rings 51 are provided on the fixing plates 5. Steel wire ropes are fixed on the fixing rings 51, and the other end of the steel wire ropes is fixed to the front end of the reciprocating lawnmower body with a suitable tension force.

[0074] In the above technical solution, these fixing plates 5 are tightly connected to the mounting base 11 by welding or other stable connection methods, ensuring its stability and reliability during operation.

[0075] A retaining ring 51 is installed on the retaining plate 5. The retaining ring 51 is designed to be very robust and can withstand large tensile and impact forces. A steel wire rope is fixed to the retaining ring 51, and the other end of the steel wire rope is fixed to the front end of the reciprocating lawnmower body with a suitable tension, that is, the power mechanism that pulls the cutter 1 and other components to move as a whole, such as on a four-wheel tractor.

[0076] The connection method between the wire rope and the reciprocating lawnmower body is crucial. It's essential to ensure that the wire rope is neither too tight, which would subject the lawnmower body to excessive tension, nor too loose, which would prevent effective securing of the cutter 1. Therefore, professional fasteners and tools must be used when connecting the wire rope to ensure a secure and reliable connection.

[0077] The main function of the steel wire rope is to secure the cutter 1, preventing the axle from breaking if the front end of the cutter 1 touches the ground during harvesting. During hay cutting, the cutter 1 may be subjected to significant impact or vibration due to uneven ground or uneven hay density. If the front end of the cutter 1 is not effectively secured, the axle may break due to contact with the ground or excessive impact. The introduction of the steel wire rope effectively solves this problem, firmly fixing the cutter 1 to the mower body and preventing damage from excessive impact or vibration.

[0078] In another technical solution, the spacing of the drafting rods 2 is 8-12 cm, the drafting rods 2 are 6-8 cm higher than the blade of the cutter 1, the front end of the drafting rods 2 is 10-15 cm longer than the front end of the blade of the cutter 1, and the angle between the front end of the drafting rods 2 and the horizontal plane is 12-18°.

[0079] In the above technical solution, the specific design of the drafting rod 2 is as follows:

[0080] Spacing: The spacing between the drafting rods 2 is designed to be 8-12 cm. This spacing is determined based on the growth density and diameter of the cowberry grass to ensure that the drafting rods 2 can effectively lift and separate the grass, while avoiding excessive spacing that could cause grass blockage or excessive resistance.

[0081] Height Setting: The height of the shovel 2 is designed to be 6-8 cm higher than the blade of the cutter 1. Firstly, this height ensures that the shovel 2 can contact the forage on the ground before the cutter 1. As the cutter moves forward, the shovel 2 first contacts the ground and, through its shape and angle, lifts the forage from the ground. This step is a prerequisite for successful forage cutting, as it ensures that the forage has been effectively separated and guided before entering the cutting path of the cutter 1. Secondly, this height avoids direct collision or interference between the shovel 2 and the blade of the cutter 1. If the shovel 2 is too low, it may come into contact with the blade of the cutter 1, which would not only damage both the shovel 2 and the cutter 1 but also reduce cutting efficiency and quality. By setting a suitable height, it ensures that the shovel 2 and the cutter 1 operate independently and efficiently within their respective working areas. However, an even more important aspect of this height setting is that it allows the cut grass to be smoothly separated from the cutter 1. After the hay is cut by the blades of cutter 1, the height of the lifting rod 2 ensures that the cut hay does not immediately come into contact with or become entangled with cutter 1 again. This helps reduce the risk of hay clogging and tangling, while improving cutting efficiency and the quality of hay collection. Furthermore, this height setting helps reduce direct contact between cutter 1 and the ground, thus extending the lifespan of cutter 1. Because the lifting rod 2 contacts the ground first and lifts the hay, cutter 1 only needs to perform the cutting operation after the hay has been lifted, thus reducing friction and impact with the ground.

[0082] Front end length: The front end of the drafting rod 2 is designed to be 10-15 cm longer than the front end of the blade of the cutter 1. This length is set to ensure that the drafting rod 2 can contact the forage before the cutter 1 and guide it onto the cutting path of the cutter 1. In this way, the forage is effectively picked up and separated before being cut, thereby improving the efficiency and quality of cutting.

[0083] Angle setting: The angle between the front end of the grass-lifting rod 2 and the horizontal plane is designed to be 12~18°. This angle setting is determined based on the growth direction of the grass and the cutting path of the cutter 1. By setting a suitable angle, the grass-lifting rod 2 can better lift the grass from the ground and guide it to the blade of the cutter 1, thereby achieving a smooth cut.

[0084] The function of drafting rod 2:

[0085] The main function of the shovel 2 is to lift the hay from the ground and guide it onto the cutter 1 for easy cutting. During hay cutting, the shovel 2 first contacts the hay on the ground and lifts it off the ground through its curved shape and suitable angle. The hay is then guided onto the cutting path of the cutter 1 and smoothly cut by the blades. This design not only improves cutting efficiency and quality but also reduces the direct contact between the cutter 1 and the ground, thus extending the service life of the cutter 1.

[0086] In another technical solution, the support base 3 includes an upper support column 32, a lower support column 33, and a threaded cylinder 34 threadedly connected to the upper support column 32 and the lower support column 33. The upper support column 32 is fixed to the bottom of the mounting base 11, and the lower support column 33 is fixed to the caster wheel 31.

[0087] In the above technical solution, the support base 3 is adjustable to adapt to different terrains and pasture heights during mowing. The support base 3 mainly consists of three parts: an upper support column 32, a lower support column 33, and a threaded cylinder 34. The top of the upper support column 32 is fixed to the bottom of the mounting base 11 by welding, bolting, or other sturdy methods to ensure its stability and reliability during operation. The bottom of the lower support column 33 is fixed to the casters 31 by bolting or other fastening methods, allowing the entire mower to move flexibly. The threaded cylinder 34 is threadedly connected to both the upper support column 32 and the lower support column 33. This connection method allows the relative position between the upper support column 32 and the lower support column 33 to be adjusted by rotating the threaded cylinder 34. The design of the threaded cylinder 34 allows it to move up and down within a certain range, thereby adjusting the distance between the cutter 1 (connected via the mounting base 11) and the ground, as well as the distance between the hoisting crank 2 (also connected to the support base 3 via the mounting base 11 or other connection methods) and the ground.

[0088] Adjustment Process: When adjusting the distance between the cutter 1 or the hoisting crank 2 and the ground, the operator can loosen the locking device (such as a nut or locking screw) securing the threaded cylinder 34. Then, by rotating the threaded cylinder 34, it can be moved up or down, thereby changing the relative height between the upper support column 32 and the lower support column 33. After adjusting to the desired position, the locking device of the threaded cylinder 34 is re-locked to ensure the stability of the support base 3. Because the threaded cylinder 34 is connected to the upper support column 32 and the lower support column 33 by threads, fine adjustments can be made, allowing the distance between the cutter 1 or the hoisting crank 2 and the ground to be precisely adjusted according to actual needs. This design enables the cutter to adapt to different grass heights and different terrain conditions, improving its applicability and flexibility.

[0089] In addition to height adjustment, the design of the support base 3 can also consider other additional functions, such as setting a shock absorption device to reduce vibration and impact during the cutting process, or setting an adjustment device to change the steering angle of the caster wheel 31, etc.

[0090] In summary, this utility model, by employing a support base 3 composed of an upper support column 32, a lower support column 33, and a threaded cylinder 34, achieves flexible adjustment of the distance between the cutter 1 and the hoisting rod 2 and the ground, thereby improving the applicability and flexibility of the creeping forage cutter. This design allows the cutter to better adapt to the cutting needs of different terrains and forage heights, thus improving cutting efficiency and the quality of forage collection.

[0091] In another technical solution, the drafting rod 2 and the cutter 1 are detachably installed, including multiple fixing seats 21, which are spaced apart on the mounting base 11. Each fixing seat 21 is provided with a mounting groove 22, and slots 23 are provided on both sides of the mounting groove 22. Each slot 23 is provided with a mounting hole.

[0092] The drafting rod 2 has a pair of mounting ears 24 at its rear end. The drafting rod 2 is inserted into the mounting groove 22 and the pair of mounting ears 24 are inserted into a pair of slots 23. Bolts are inserted through the mounting holes and the mounting ears 24 and fastened with nuts.

[0093] In the above technical solution, the drafting rod 2 and the cutter 1 are installed in a detachable manner to facilitate the installation and removal of the drafting rod 2, thereby improving the maintainability and flexibility of the equipment.

[0094] Multiple fixing seats 21 are spaced apart on the mounting base 11. These fixing seats 21 are fixed to the mounting base 11 by welding, bolting, or other secure methods to ensure stability and reliability during operation. Each fixing seat 21 has a mounting groove 22, the shape and size of which match the rear end of the drafting rod 2, so that the drafting rod 2 can be smoothly inserted. On both sides of the mounting groove 22, slots 23 are respectively opened. The shape and size of the slots 23 match the mounting ears 24 on the drafting rod 2, so that the mounting ears 24 can be smoothly inserted into the slots 23. Mounting holes are also opened in the slots 23. These mounting holes are used to pass bolts to fix the drafting rod 2 to the fixing base 21. A pair of mounting ears 24 are provided on the rear end of the drafting rod 2. The shape and size of this pair of mounting ears 24 match the slots 23, so that the drafting rod 2 can be smoothly inserted into the mounting groove 22, and the mounting ears 24 can be smoothly inserted into the slots 23. When installing the drafting rod 2, first insert the rear end of the drafting rod 2 into the mounting slot 22, while ensuring that the pair of mounting ears 24 are respectively inserted into the pair of slots 23. Then, pass the bolts through the mounting holes and mounting ears 24, and tighten them with nuts. By adjusting the tightness of the bolts and nuts, it can be ensured that the drafting rod 2 is firmly fixed on the mounting base 21.

[0095] When it is necessary to disassemble the drafting rod 2, simply loosen the nut and remove the bolt to remove the drafting rod 2 from the mounting slot 22 and the recess 23. This detachable installation method makes the replacement and maintenance of the drafting rod 2 more convenient and quick.

[0096] In summary, this utility model achieves convenient and quick installation and disassembly between the drafting rod 2 and the cutter 1 by adopting a detachable installation method. This design not only improves the maintainability and flexibility of the equipment, but also makes it easier to replace the drafting rod 2 and adapt it to different cutting needs.

[0097] In another technical solution, an angle adjuster 6 is also included, which comprises:

[0098] A pair of housings 61 are disposed opposite to each other on both sides of the mounting base 11;

[0099] A rotating shaft 62 is rotatably mounted on a pair of housings 61 at both ends. Near the two ends of the rotating shaft 62, baffles 63 are provided radially, and arc-shaped slides are provided on the baffles 63.

[0100] Two push rods 64, each push rod 64 has a sliding head 65 at its front end and a thread at its rear end. The sliding head 65 is slidably connected to the arc-shaped slide rail on the baffle 63. A pulley 66 is coaxially mounted on the push rod 64, and a belt is tensioned between the two pulleys 66.

[0101] Two guide cylinders 67 are respectively disposed at the rear end of a pair of housings 61. The guide cylinders 67 are threaded. The rear end of the push rod 64 is threaded to the guide cylinders 67 and extends rearward through the housings 61.

[0102] A handwheel 68 is located on the part of the push rod 64 that extends out of the housing 61;

[0103] The fixed seat 21 is mounted on the rotating shaft 62. When the push rod 64 moves to the front end, it pushes the baffle 63 to move forward and upward, causing the rotating shaft 62 to rotate, the fixed seat 21 to rotate, and the drafting rod 2 to rotate.

[0104] In the above technical solution, the angle of the drafting rod 2 can be adjusted by the angle adjuster 6 to adapt to different forage cutting needs.

[0105] The angle adjuster 6 includes a pair of opposing housings 61, which are securely mounted on both sides of the mounting base 11. The shape and size of the housings 61 are designed to accommodate and support other components of the angle adjuster 6. A rotating shaft 62 is rotatably mounted on each of the two housings 61. The rotating shaft 62 can rotate freely about its axis. Near the ends of the rotating shaft 62, baffles 63 are radially arranged. These baffles 63 are used to slidably connect with slide heads 65 on the push rod 64 to transmit the thrust of the push rod 64. The baffles 63 have arc-shaped tracks whose shape and size match the slide heads 65 to ensure smooth sliding of the slide heads 65. The front end of the push rod 64 is rotatably mounted with the slide head 65, which slidably connects to the arc-shaped tracks on the baffles 63. When the push rod 64 moves, the slide head 65 slides on the tracks, thereby pushing the baffles 63 to move. The rear end of the push rod 64 is threaded for threaded connection with a guide cylinder 67. A pulley 66 is coaxially mounted on the push rod 64, and a belt is tensioned between the two pulleys 66. By rotating the handwheel 68 of one push rod 64, the other push rod 64 can be moved synchronously. Two guide cylinders 67 are respectively located at the rear end of the two housings 61. The guide cylinders 67 are threaded, matching the thread at the rear end of the push rod 64. The rear end of the push rod 64 is threaded onto the guide cylinder 67 and can extend out from the rear end of the housing 61. The handwheel 68 is located on the part of the push rod 64 that extends out of the housing 61, making it convenient for the operator to rotate.

[0106] A fixed base 21 is mounted on a rotating shaft 62 for mounting the drafting crank 2. When the rotating shaft 62 rotates, the fixed base 21 and the drafting crank 2 rotate accordingly, thereby changing the angle of the drafting crank 2. When the angle of the drafting crank 2 needs to be adjusted, the operator can turn a handwheel 68. The rotation of the handwheel 68 drives a push rod 64 to rotate, which is transmitted to another push rod 64 via a belt, causing the two push rods 64 to move synchronously. The movement of the push rod 64 pushes a baffle 63 to slide along an arc-shaped track, thereby driving the rotating shaft 62 to rotate. The rotation of the rotating shaft 62 drives the fixed base 21 and the drafting crank 2 to rotate, thereby changing the angle of the drafting crank 2. The shape and size of the arc-shaped track determine the range of movement that the push rod 64 can push the baffle 63, and thus determine the range of angles that the rotating shaft 62 and the drafting crank 2 can rotate. By designing arc-shaped tracks of different shapes and sizes, different forage cutting needs can be met. To improve the stability and reliability of the angle adjuster 6, lubrication components such as bearings can be installed between the housing 61 and the rotating shaft 62 to reduce friction and wear.

[0107] In another technical solution, a spacing adjuster 7 is also included, which comprises:

[0108] Multiple sliding seats 71 are slidably sleeved on the rotating shaft 62 at intervals. Each sliding seat 71 is provided with a sliding cylinder 72. The inner wall of the sliding cylinder 72 is provided with a sliding ridge 73 protruding towards the center. The sliding ridge 73 is arranged axially. The rotating shaft 62 is provided with a sliding groove 60. The sliding groove 60 is arranged axially, and the sliding ridge 73 is slidably engaged in the sliding groove 60.

[0109] The sliding seat 71 and the sliding cylinder 72 are provided with a plurality of positioning holes, the positioning holes are provided with threads, and the side wall of the rotating shaft 62 is provided with an elongated positioning groove 69 corresponding to the positioning holes, the positioning groove 69 being arranged along the axial direction;

[0110] Multiple positioning screws 74 are screwed through the positioning holes and abut against the positioning grooves 69;

[0111] The fixed seat 21 is disposed on the sliding seat 71.

[0112] In the above technical solution, the spacing between the drafting rods 2 can be adjusted by the spacing adjuster 7 to adapt to different forage cutting needs.

[0113] The spacing adjuster 7 includes multiple sliding seats 71, which are slidably mounted on the rotating shaft 62 at intervals. The sliding seats 71 can slide freely along the axial direction of the rotating shaft 62 to adjust their position. Each sliding seat 71 is provided with a sliding cylinder 72, the inner wall of which has a sliding rib 73 protruding towards the center. These sliding ribs 73 are axially arranged to slide and engage with the sliding grooves 60 on the rotating shaft 62, ensuring the stability of the sliding seat 71 as it slides on the rotating shaft 62. Multiple sliding grooves 60 are axially arranged on the rotating shaft 62. The shape and size of these grooves 60 match the sliding ribs 73 on the inner wall of the sliding cylinder 72 to ensure that the sliding ribs 73 can slide smoothly within the grooves 60. When the sliding seat 71 slides along the rotating shaft 62, the sliding ribs 73 slide within the grooves 60, thereby maintaining the stability of the sliding seat 71 and preventing it from rotating around the rotating shaft 62. Multiple positioning holes are correspondingly formed on the sliding seats 71 and the sliding cylinders 72. These locating holes are threaded for screwing in locating screws 74. Elongated locating grooves 69 are formed on the side wall of the rotating shaft 62 corresponding to the locating holes. These locating grooves 69 are axially oriented to accommodate and abut the heads of the locating screws 74. When it is necessary to fix the position of the sliding seat 71, the locating screws 74 can be screwed through the locating holes, with their heads extending into and abutting against the locating grooves 69. By adjusting the tightness of the locating screws 74, it can be ensured that the sliding seat 71 is securely fixed in the desired position on the rotating shaft 62.

[0114] A fixed seat 21 is mounted on a sliding seat 71 for mounting the drafting crank 2. When the position of the sliding seat 71 changes, the positions of the fixed seat 21 and the drafting crank 2 also change, thereby adjusting the spacing between the drafting cranks 2. When adjusting the spacing between the drafting cranks 2, the operator can first loosen the positioning screw 74, allowing the sliding seat 71 to slide freely on the rotating shaft 62. Then, according to the required spacing, slide the sliding seat 71 axially along the rotating shaft 62 to the desired position. Finally, retighten the positioning screw 74 so that its head abuts against the positioning groove 69, thereby fixing the position of the sliding seat 71.

[0115] To improve the stability and reliability of the pitch adjuster 7, a lubrication component, such as lubricating oil or grease, can be provided between the sliding seat 71 and the rotating shaft 62 to reduce friction and wear. Simultaneously, a locking device, such as a locking plate or locking screw, can be provided on the positioning screw 74 to prevent it from loosening due to vibration or external force. <Example>
