Description

Technical Field

[0001] This invention relates to the fields of metamaterials and vibration reduction engineering technology, and in particular to a vibration suppression device for a sugarcane leaf recycling and baling mechanism in intelligent agricultural machinery. Background Technology

[0002] Currently, with the accelerated advancement of agricultural mechanization and intelligentization, high-end agricultural machinery such as high-horsepower tractors, combine harvesters, seeders, and sugarcane balers are placing increasingly stringent performance requirements on their core transmission systems. These systems must balance lightweight design, high reliability, low vibration, and excellent shock resistance to adapt to the complex and bumpy working conditions in the field, meeting the dual demands of long-term heavy-load operation and improved energy efficiency. Traditional web-plate gears, which reduce weight to some extent by creating simple circular holes or slots in the web, disrupt the continuity of the material and the force transmission path, leading to significant stress concentration. This often comes at the cost of sacrificing the overall structural rigidity and bending strength, making them unsuitable for the operating environment of agricultural machinery.

[0003] To address the aforementioned problems, this invention proposes a vibration suppression device for the sugarcane leaf recycling and baling mechanism of intelligent agricultural machinery. This device innovatively combines a porous spiral layer structure with a web-type gear to form a spiral hollow-filled porous structure with directional mechanical properties, which is then applied to the gear web. This structural design achieves gear lightweighting and improved axial stiffness, while also possessing axial impact resistance, energy absorption, and vibration reduction functions. It fills a technological gap in related fields and has significant application value in promoting the development of agricultural machinery transmission technology. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies and fill related technological gaps, this invention provides a vibration suppression device for a sugarcane leaf recycling and baling mechanism in intelligent agricultural machinery. The technical solution adopted by this invention to solve its technical problem is as follows:

[0005] A vibration suppression device for a sugarcane leaf recycling and baling mechanism in intelligent agricultural machinery is characterized by comprising: a porous spiral web drive gear and a porous spiral web driven gear; the porous spiral web drive gear and the porous spiral web driven gear mesh with each other, both of which adopt a porous spiral structure web, and the tooth profile is asymmetrical on both the working end side and the non-working end side, which can improve the bending load capacity of the tooth root, extend the service life of the gear, and reduce the vibration of the gear pair; both the porous spiral web drive gear and the porous spiral web driven gear are manufactured using an integral molding technology, and the overall component material composition and density are consistent;

[0006] The porous spiral structure web has three configurations: spiral hollow, spiral hollow filled hexagon, and spiral hollow filled circular. The spiral hollow structure web uses hexagonal tubes as the basic unit. Multiple sets of hexagonal tubes are interconnected and arranged around the central axis to form a ring-shaped main body. There is a cross-grid connection area between adjacent axial hexagonal tubes, and adjacent layers rotate around the central axis by a set angle, which ranges from 40° to 90°. Its unique spiral path design can guide the stress to be evenly distributed when bearing load, effectively avoiding stress concentration.

[0007] The spiral hollow filled hexagonal structure web is formed by adding small hexagonal tubular cores to the basic unit of the spiral hollow structure web. Its configuration and connection method are as follows: The small hexagonal tubular cores are centrally located inside the hexagonal tube. The small hexagonal tubular cores and the hexagonal tube are arranged concentrically and in the same direction. Each inner corner vertex of the small hexagonal tubular core is fixedly connected to the corresponding inner corner vertex of the hexagonal tube through radially extending partitions. The center line of the partitions coincides with the radial line connecting one inner corner vertex of the small hexagonal tubular core and the corresponding inner corner vertex of the hexagonal tube. The wall thickness of the small hexagonal tubular core is uniform and consistent with the thickness of the partitions. Both thicknesses are slightly less than the uniform wall thickness of the hexagonal tube, forming a spiral hollow filled hexagonal structure web composed of a double-layered hexagonal tubular structure in the same direction and radially corresponding partitions.

[0008] The wall thickness of the small hexagonal tubular core is uniform, and the wall thickness of the small hexagonal tubular core is the same as the thickness of the partition. Both of their thicknesses are less than the wall thickness of the outer hexagonal tube. The side length of the circumscribed regular hexagon of the small hexagonal tubular core is about 2 / 5 of the side length of the circumscribed regular hexagon of the outer hexagonal tube.

[0009] The spiral hollow filled hexagonal web structure can effectively avoid stress concentration. The continuous support surface inside the structure provides a stable load transfer interface. The additional small hexagonal tubular core and radial partition form a double-layer hexagonal bearing force system, which not only strengthens the axial deformation stiffness of the web, but also further enhances the multi-directional load dispersion ability through the symmetrical composite cell structure. Compared with the unfilled configuration, its torsional and compressive resistance is significantly enhanced.

[0010] The spiral hollow filled circular structure web is formed by adding a circular tubular core to the basic unit of the spiral hollow structure web. Its configuration and connection method are as follows: the circular tubular core is centrally located inside the hexagonal tube. The outer wall of the circular tubular core is fixedly connected to the six inner corners of the hexagonal tube by radially extending partitions. The included angle between two adjacent partitions is 60°. The thickness of the partition is slightly less than the wall thickness of the hexagonal tube, and the wall thickness of the circular tubular core is the same as the thickness of the partition, forming a spiral hollow filled circular structure web composed of the inner circular tubular core and the radial partitions.

[0011] The circular tubular core has a uniform wall thickness, and the wall thickness of the circular tubular core is the same as that of the partition plate. Both of their thicknesses are less than the wall thickness of the outer hexagonal tube. The outer diameter of the circular tubular core is approximately 2 / 5 of the diameter of the inscribed circle of the outer hexagonal tube.

[0012] The spiral hollow-filled circular structure web can effectively avoid stress concentration. The continuous support surface inside the structure provides a stable load transfer interface. The circular tubular core inside the structure and the outer hexagonal tube wall work together through radial ribs to further optimize the uniformity of stress distribution. This design of circular filling and rib connection significantly improves the axial energy absorption efficiency and deformation stability of the structure, enabling it to dissipate more energy through a controllable and gradual crushing process under extreme impact loads, thereby providing excellent passive safety protection and vibration damping performance for the transmission system.

[0013] The multi-hole spiral web drive gear and multi-hole spiral web driven gear are divided into two categories according to the number of web configurations used: single-structure multi-hole spiral web gear and double-structure multi-hole spiral web gear. The single-structure multi-hole spiral web gear adopts a single web configuration, which can be a spiral hollow configuration, a spiral hollow filled hexagonal configuration, or a spiral hollow filled circular configuration. The double-structure multi-hole spiral web gear adopts a combination of two different web configurations, which can be any two of the three configurations.

[0014] The dual-structure porous spiral web gear has a web with two different configurations, including three types: hollow hexagonal-porous spiral web, hollow circular-porous spiral web, and hollow hexagonal-circular coupled porous spiral web. Each type of web has a symmetrical structure from the end face to the middle, and is formed by sequentially combining the corresponding two web configurations. Specifically, the hollow hexagonal-porous spiral web is composed of a spiral hollow structure and a spiral hollow filled hexagonal structure; the hollow circular-porous spiral web is composed of a spiral hollow structure and a spiral hollow filled circular structure; and the hollow hexagonal-circular coupled porous spiral web is composed of a spiral hollow filled hexagonal structure and a spiral hollow filled circular structure. Adjacent axial layers of each type of web are integrally connected by a connecting surface of equal thickness, and adjacent layers rotate relative to each other around the central axis by a set angle, the value of which ranges from 40° to 90°.

[0015] Compared with the prior art, the beneficial effects of the present invention are: it can significantly reduce the weight of gears in agricultural machinery equipment while effectively improving their axial stiffness, so that the gears have both excellent axial impact resistance and energy absorption performance and vibration reduction function, which can enhance the operational reliability of the transmission system under complex working conditions such as overload and high-frequency vibration, and has important application value in vibration reduction engineering of agricultural machinery equipment.

Its unique spiral path design can guide the uniform distribution of stress when bearing loads, effectively avoiding stress concentration. It should be noted that when setting the interlayer rotation angle of the spiral hollow structure web, 44° is selected as the optimal angle for this structure, and different rotation angles can be selected according to actual needs.

Each interior vertex of the small hexagonal tubular core is fixedly connected to the corresponding interior vertex of the hexagonal tube via radially extending partitions. Furthermore, the centerline of the partitions is aligned with one interior vertex of the small hexagonal tubular core and... The radial lines connecting the corresponding interior vertices of the hexagonal tubes coincide. The wall thickness of the small hexagonal tubular core is uniform and consistent with the thickness of the partition. Both thicknesses are slightly less than the uniform wall thickness of the hexagonal tubes, forming a spiral hollow-filled hexagonal structure web 3 composed of a double-layered unidirectional hexagonal tubular structure and radially corresponding partitions. It should be noted that when setting the interlayer rotation angle of the spiral hollow-filled hexagonal structure web 3, 82° is selected as the optimal angle for this structure. Different rotation angles can be selected according to actual needs.

It should be noted that when setting the interlayer rotation angle of the spiral hollow filled circular structure web 4, 86° is selected as the optimal angle for this structure. Different rotation angles can be selected according to actual needs.
