Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a cutting device and harvesting machinery. Background Technology

[0002] Sugarcane is an important sugar crop, and sugarcane cutting technology is a key technology for sugarcane harvesters. During sugarcane harvesting, the sugarcane stalks are cut into segments of a certain size using cutters and cutting devices installed on the harvester. However, the cutting devices in existing sugarcane harvesters all use flat-edged blades with blades. Over time, the sharpness of the blades becomes insufficient, making it difficult to meet the cutting requirements and reducing the harvester's working efficiency. Utility Model Content

[0003] In view of at least one of the above-mentioned defects or deficiencies in the prior art, the present invention provides a cutting device and harvesting machinery to achieve efficient cutting.

[0004] To achieve the above objectives, this utility model provides a slicing device, which includes: A slicing roller assembly includes an upper slicing roller and a lower slicing roller. The upper slicing roller is connected to a plurality of upper slicing blades, and the lower slicing roller is connected to a plurality of lower slicing blades. At least one of the upper slicing blades and the lower slicing blades is a serrated slicing blade, and the cutting edge of the serrated slicing blade includes a plurality of serrations. A drive assembly connects the upper cutting roller and the lower cutting roller, and the drive assembly is used to drive the upper cutting roller and the lower cutting roller to rotate in opposite directions.

[0005] In some embodiments, the upper cutting blade is a flat cutting blade with a flat cutting edge, and the lower cutting blade is a serrated cutting blade.

[0006] In some embodiments, the serrated cutting blade includes two opposing cutting edges, both of which are serrated.

[0007] In some embodiments, the distance between the centers of any two saw teeth ranges from 2 mm to 15 mm, and the width of the tip of each saw tooth ranges from 1 mm to 2 mm.

[0008] In some embodiments, the cutting edges of the upper cutting blade and the lower cutting blade are designed to overlap at the cutting position.

[0009] In some embodiments, the drive assembly includes a drive member and a gearbox, the upper cutting roller and the lower cutting roller are connected by the gearbox, and one of the upper cutting roller and the lower cutting roller is connected to the drive member, so that the drive member drives the upper cutting roller and the lower cutting roller to rotate synchronously through the gearbox.

[0010] In some embodiments, the slicing device further includes: Two fixed seats are respectively connected to the ends of the upper cutting roller and the lower cutting roller, and the fixed seats are used to connect the cutting device to external machinery.

[0011] In some embodiments, the upper cutting blade is detachably connected to the upper cutting roller, and the lower cutting blade is detachably connected to the lower cutting roller.

[0012] In some embodiments, the upper cutting roller is provided with a plurality of upper clamping plates, the number of upper clamping plates corresponding to the number of upper cutting blades. Each upper clamping plate is provided with a clamping groove and a plurality of limiting holes. The clamping groove is used to clamp and accommodate the upper cutting blades, and the limiting holes are used for a locking member to pass through. The locking member is used to abut against the upper cutting blades. And / or, The lower cutting roller is provided with multiple lower clamping plates, the number of which corresponds to the number of lower cutting blades. Each lower clamping plate is provided with a clamping groove and multiple limiting holes. The clamping groove is used to clamp and accommodate the lower cutting blade, and the limiting holes are used for a locking member to pass through. The locking member is used to abut against the lower cutting blade.

[0013] The second aspect of this utility model provides a harvesting machine, which includes a cutting device as described in any one of the above claims.

[0014] Through the above technical solution, the cutting edge of the serrated cutting blade is composed of multiple serrations. The sharper serrations can increase the piercing pressure of the serrated cutting blade on the sugarcane peel under the same clamping force, effectively solving the problem that smooth cutting edges are prone to slipping when cutting tough sugarcane peel and require greater pressure. This significantly increases the cutting strength, achieves efficient and clean cutting, and improves cutting efficiency. Moreover, during the rotation process, the serrated cutting blade can effectively entangle weeds and temporarily retain them in the gaps between the teeth, rather than pushing them out as a whole like smooth blades. This prevents weeds from entering the subsequent impurity removal system with the sugarcane material flow, thereby reducing the impurity content of the sugarcane harvest at the source, improving the harvest quality, and reducing the load and clogging risk of the impurity removal system.

[0015] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0017] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0019] like Figure 1 and Figure 2As shown, this utility model provides a slicing device, which includes slicing rollers 1 and a driving assembly 2. The slicing rollers 1 include an upper slicing roller 11 and a lower slicing roller 12. The upper slicing roller 11 is connected to a plurality of upper slicing blades 111, and the lower slicing roller 12 is connected to a plurality of lower slicing blades 121. At least one of the upper slicing blades 111 and the lower slicing blades 121 is a serrated slicing blade, and the cutting edge of the serrated slicing blade includes a plurality of serrations. The driving assembly 2 is connected to the upper slicing roller 11 and the lower slicing roller 12, and the driving assembly 2 is used to drive the upper slicing roller 11 and the lower slicing roller 12 to rotate in opposite directions. The cutting roller 1 includes an upper cutting roller 11 and a lower cutting roller 12 arranged in parallel. Multiple circumferentially distributed upper cutting blades 111 and lower cutting blades 121 are mounted on the surfaces of the two rollers. Either the upper cutting blade 111 or the lower cutting blade 121 is a serrated cutting blade, or both the upper cutting blade 111 and the lower cutting blade 121 are serrated cutting blades. The serrated cutting blades have multiple fine serrations, each with a tooth tip width of less than 2mm, resulting in a more refined and sharp cutting edge structure. The drive assembly 2 is connected to the upper cutting roller 11 and the lower cutting roller 12, driving them to rotate in opposite directions. This allows the upper cutting blades 111 and the lower cutting blades 121 to interleave and cut during rotation, achieving continuous cutting of materials such as sugarcane.

[0020] The serrated cutting blade consists of multiple serrations. The sharper serrations increase the piercing pressure on the sugarcane peel under the same clamping force, effectively solving the problem of slippage and the need for greater pressure when cutting tough sugarcane peel with a smooth blade. This significantly increases the cutting strength, achieving efficient and clean cuts and improving cutting efficiency. Moreover, during rotation, the serrated cutting blade effectively entangles and temporarily retains weeds in the tooth gaps, rather than pushing them out as a whole like a smooth blade. This prevents weeds from entering the subsequent impurity removal system with the sugarcane material flow, thereby reducing the impurity content of the sugarcane harvest at the source, improving harvest quality, and reducing the load and clogging risk of the impurity removal system.

[0021] In some embodiments, the upper cutting blade 111 is a flat cutting blade with a flat cutting edge, and the lower cutting blade 121 is a serrated cutting blade. During operation, the drive assembly 2 drives the upper cutting roller 11 and the lower cutting roller 12 to rotate in opposite directions. When material (such as sugarcane stalks and weeds) enters the interlocking area between the upper cutting roller 11 and the lower cutting roller 12, the rotating serrated cutting blade first penetrates and hooks the material with its sharp teeth, forming an effective grip and initial tear, while the flat cutting blade above works in conjunction with the serrated blade to complete the final shearing and cutting of the material. The lower cutting blade 121 has a serrated design, with multiple sharp teeth increasing local pressure and making it more powerful. This allows it to easily tear tough sugarcane fibers, while the serrated structure effectively traps soft weeds within its gaps, preventing them from flowing with the material and thus reducing impurities at the source. Weeds can be manually removed after each day's harvest. The upper cutting blade 111 has a flat blade. After cutting the material, the flat back of the blade provides a continuous and smooth guide surface for the cut sugarcane segments, enabling effective and neat delivery of the segments. This prevents the cut segments from congesting or rolling in the cutting area, ensuring smooth output.

[0022] In some implementations, such as Figure 4 As shown, the serrated cutting blade includes two opposing cutting edges, both of which are serrated. Both sides of the blade body have cutting edges, and since both edges are serrated, the serrated cutting blade is a symmetrical structure where both sides can serve as effective working edges. When installed on the lower cutting roller 12, whether in initial installation or subsequent adjustments, both sides of the blade have identical serrated cutting edge geometry. For example, Figure 6 surround Figure 7 As shown, the two blades on either side of the serrated cutting blade can be either mirror-symmetrical or centrally symmetrical. A mirror-symmetrical serrated cutting blade can be reinstalled simply by rotating it 180 degrees up and down on its own plane after disassembly. A centrally symmetrical serrated cutting blade can be reinstalled simply by rotating it 180 degrees around its own axis after disassembly, making it easy to distinguish the blade orientation. When one blade becomes dull after long-term use, the operator does not need to replace it with a new blade; simply disassemble and flip the blade for reinstallation, and the other side of the serrated blade can be used immediately to continue working. This extends the service life of the serrated cutting blade, reduces the need for spare blade inventory and replacement frequency, and improves the continuity and overall economy of sugarcane harvesting operations.

[0023] In some embodiments, the distance between the centers of any two saw teeth ranges from 2mm to 15mm, and the width of the tip of each saw tooth ranges from 1mm to 2mm. For example... Figure 4 and Figure 5As shown in the diagram, S1 represents the width of the serration tip, and S2 represents the distance between the centers of two serrations. An appropriate tooth pitch range ensures a sufficient number of serrations per unit length, forming a continuous and efficient cutting line while avoiding the weakening of strength and clogging problems caused by excessively small tooth pitch. This results in higher efficiency and less resistance when cutting tough sugarcane fibers. Furthermore, since sugarcane is typically 30mm in diameter, a distance of less than 15mm between the centers of any two serrations ensures that at least one serration passes through the sugarcane, preventing it from passing between two serrations. Simultaneously, a tooth tip width of 1mm to 2mm makes the serration tip sharp, easily penetrating and tearing plant tissue, increasing cutting strength. This parameter combination achieves a good balance between sharpness and durability, ensuring excellent cutting performance while avoiding premature wear or chipping due to excessively thin tooth tips, thus extending the tool's lifespan and improving the reliability and economy of the cutting device.

[0024] In some implementations, such as Figure 3 As shown, the cutting edges of the upper cutting blade 111 and the lower cutting blade 121 are designed to overlap at the cutting position. Specifically, when the cutting blades mounted on the upper cutting roller 11 and the lower cutting roller 12 rotate in opposite directions with the rollers, the tips of the cutting edges of the upper cutting blade 111 and the lower cutting blade 121 overlap by a certain amount in the radial direction of the two rollers, rather than merely brushing past each other. That is, at the moment of cutting, the two cutting blades do not just make point contact, but form a small intersecting area, achieving a scissor-like closed shearing action on the material.

[0025] The overlapping of the blades of the upper cutting blade 111 and the lower cutting blade 121 ensures thorough and reliable cutting. The overlapping blades can cut sugarcane stalks without any omissions, effectively preventing stalk pulling and peel tearing caused by incomplete cutting, thus ensuring neat segments and reducing juice loss caused by fiber pulling. This forced shearing action is particularly effective against weeds and sugarcane leaves entangled on the sugarcane, completely cutting them off so that the weeds and sugarcane leaves entering the impurity removal system are small, multi-segmented pieces that can be removed, resulting in a high impurity content in the sugarcane segments transported to the sugar mill. Moreover, it avoids rigid collisions that may occur between the blades. By controlling the amount of overlap, it achieves both effective cutting and blade protection, improving the stability of equipment operation and the service life of the blades.

[0026] In some embodiments, the drive assembly 2 includes a drive element 21 and a gearbox 22. The upper cutting roller 11 and the lower cutting roller 12 are connected by the gearbox 22, and one of the upper cutting roller 11 and the lower cutting roller 12 is connected to the drive element 21, so that the drive element 21 drives the upper cutting roller 11 and the lower cutting roller 12 to rotate synchronously through the gearbox 22. The drive assembly 2 includes a drive element 21 and a gearbox 22, wherein the drive element 21 can be a hydraulic motor or an electric motor. The shaft ends of the upper cutting roller 11 and the lower cutting roller 12 both extend into the gearbox 22 and are connected by a set of meshing gears, wherein the gears can be spur gears or helical gears with a speed ratio of 1:1. During operation, the drive unit 21 directly drives the upper cutting roller 11 or the lower cutting roller 12. Either the upper cutting roller 11 or the lower cutting roller 12 rotates as the active roller. The rotational power of the active roller is transmitted to the driven roller through the meshing gear pairs in the gearbox 22, so that the upper cutting roller 11 and the lower cutting roller 12 rotate synchronously at the same speed but in opposite directions.

[0027] The gearbox 22 ensures synchronization of the rotational phase and linear velocity between the upper cutting roller 11 and the lower cutting roller 12, enabling the upper cutting blade 111 and the lower cutting blade 121 to precisely overlap and shear at the cutting position according to the preset trajectory. This avoids problems such as incomplete cutting, blade collision, or material blockage that may be caused by asynchronous speeds, greatly improving the reliability of the cutting action and the quality of the cut. Secondly, this structure simplifies the power source of the entire cutting roller 1 into a single drive unit 21, distributing power through highly reliable gear meshing within the gearbox 22. This not only simplifies the transmission system and reduces manufacturing costs and maintenance complexity, but its rigid connection characteristics also ensure that the two rollers remain synchronized even under impact loads. This guarantees that the cutting device can work stably and efficiently continuously when dealing with sugarcane stalks of different diameters and toughnesses.

[0028] In some embodiments, the cutting device further includes two fixed seats 3, respectively connected to the ends of the upper cutting roller 11 and the lower cutting roller 12. The fixed seats 3 are used to connect the cutting device to external machinery. The ends of both the upper cutting roller 11 and the lower cutting roller 12 are connected to fixed seats 3. The fixed seats 3 are reliably connected to the connecting discs 4 of the upper cutting roller 11 and the lower cutting roller 12 via bearings 31. The fixed seats 3 provide an interface for the entire cutting device to rigidly connect to an external host machine (such as a sugarcane harvester frame), thereby firmly fixing the cutting rollers 1 and their drive assembly 2 in the set working position. Connecting discs 4 are provided on both axial sides of the upper cutting roller 11 and the lower cutting roller 12, facilitating the connection of the upper cutting roller 11 and the lower cutting roller 12 to external components. The fixed base 3 forms the installation foundation for the entire cutting device, transmitting and distributing the cutting reaction force, material impact vibration, and driving torque generated by the cutting rollers 1 during operation to the main frame. This ensures that the upper cutting roller 11 and the lower cutting roller 12 maintain a precise relative positional relationship, i.e., a stable shaft spacing and precise blade overlap, even under high-speed rotation and impact loads. Furthermore, this modular connection method facilitates equipment installation, commissioning, and maintenance, allowing the entire cutting device to be quickly assembled and disassembled as a complete assembly. This provides convenience for subsequent maintenance and improves the overall reliability and service life of the equipment.

[0029] In some embodiments, the upper cutting blade 111 is detachably connected to the upper cutting roller 11, and the lower cutting blade 121 is detachably connected to the lower cutting roller 12. The upper cutting blade 111 can be detachably connected by mechanical locking parts 113 such as bolts or slots; similarly, the lower cutting blade 121 is also installed on the lower cutting roller 12 in a similar detachable manner, making the upper cutting blade 111 and the lower cutting blade 121 an independent, quick-release component, while the upper cutting roller 11 and the upper cutting blade 111 serve as the base for installation and drive. When the cutting blade wears down or is accidentally damaged after long-term use, maintenance personnel do not need to replace or disassemble the entire cutting roller assembly. They only need to loosen the locking parts 113 to remove the individual worn blade and replace it with a new blade or an old blade that has been sharpened and repaired. This simplifies maintenance work, shortens downtime, and reduces maintenance and operating costs. Meanwhile, this modular design also gives the equipment good adaptability, allowing for quick replacement of special cutting blades with different tooth shapes, tooth pitches or materials according to different harvested materials (such as different varieties and thicknesses of sugarcane) or different cutting length requirements, thereby optimizing the cutting effect and improving the overall operational flexibility and comprehensive economic benefits of the harvester.

[0030] In some embodiments, the upper cutting roller 11 is provided with a plurality of upper clamping plates 112, the number of upper clamping plates 112 corresponding to the number of upper cutting blades 111. Each upper clamping plate 112 is provided with a clamping groove and a plurality of limiting holes 1121. The clamping groove is used to clamp and accommodate the upper cutting blades 111, and the limiting holes 1121 are used for the locking member 113 to pass through. The locking member 113 is used to abut against the upper cutting blades 111. And / or, The lower cutting roller 12 is provided with multiple lower clamping plates 122, the number of lower clamping plates 122 corresponding to the number of lower cutting blades 121. Each lower clamping plate 122 is provided with a clamping groove and multiple limiting holes 1121. The clamping groove is used to clamp and accommodate the lower cutting blades 121, and the limiting holes 1121 are used for the locking member 113 to pass through. The locking member 113 is used to abut against the lower cutting blades 121.

[0031] Specifically, multiple upper clamping plates 112 are arranged at specific intervals on the circumferential surface of the upper cutting roller 11. In the embodiment provided by this utility model, three upper clamping plates 112 are arranged at intervals. Each upper clamping plate 112 is machined with a clamping groove for accommodating the upper cutting blade 111 and has multiple limiting holes 1121. During installation, the root of the upper cutting blade 111 is embedded into the clamping groove for positioning. Then, a locking member 113 is used to pass through the limiting holes 1121 and apply torque, so that the end of the locking member 113 abuts against the blade of the upper cutting blade 111. Thus, the upper cutting blade 111 is pressed and fixed in the clamping groove of the clamping plate by friction and the cooperation of the clamping groove. The lower cutting roller 12 adopts the same method, and the lower cutting blade 121 is fixed by the lower clamping plate 122 and the locking member 113. The locking element 113 can be a bolt, and the groove wall of the limiting hole 1121 has threads. By engaging with the threads of the bolt, the cutting blade can be locked.

[0032] The clamping groove provides stable and precise positioning for the cutting blades, ensuring that all blades have a consistent extension height and rotation radius after installation, thereby guaranteeing the accuracy of the cutting trajectory. The combination of multiple limiting holes 1121 and locking elements 113, through uniform force applied at multiple points, firmly locks the cutting blades within the clamping groove, effectively preventing loosening, displacement, or vibration of the blades under high-speed rotation and impact cutting loads, enhancing the reliability of the fixation and the stability of operation. Simultaneously, this structure makes blade replacement very simple and safe; disassembly and assembly can be completed by simply tightening or loosening a few locking elements 113, improving maintenance efficiency and helping to maintain the consistency of the entire cutting device's working accuracy.

[0033] A second aspect of this invention provides a harvesting machine, which includes a cutting device as described in any of the above claims. The cutting device can be mounted on the frame of the harvesting machine via a mounting base 3, typically located after the sugarcane lifting and cutting mechanisms and before the impurity removal and conveying systems. In the overall machine transmission system, the prime mover of the harvesting machine distributes power to the drive component 21 of the cutting device, which in turn drives the upper cutting roller 11 and the lower cutting roller 12 to rotate synchronously in opposite directions according to a set phase and speed via a gearbox 22.

[0034] The high-strength and high-efficiency cutting characteristics of the serrated cutting blades in the segmenting device ensure that sugarcane stalks can be quickly and neatly cut into regular segments, laying a good foundation for feeding and subsequent processing. The serrated blades' ability to entangle weeds greatly reduces the total amount of impurities entering the subsequent impurity removal and conveying systems, significantly reducing the impurity content of the harvested material and improving the purity and quality of the harvested sugarcane. At the same time, the reliable rigid transmission, detachable blade design, and stable installation of the segmenting device itself ensure the continuity and stability of the machine's operation in complex field environments, reducing downtime for maintenance, thereby comprehensively improving the operating efficiency, reliability, and economy of the harvesting machinery.
