Description
Technical field
The utility model relates to agricultural machinery, relates in particular to the non-circular cone bevel gear of a kind of high-speed transplanter two-stage wide-narrow row transplanting mechanism that is suitable for high-speed transplanter wide-and narrow-row rice transplanting requirement.
Background technology
The wide-and narrow-row rice transplanting refers to that the line space of rice transplanter institute rice transplanting seedling carries out one wide one narrow planting patterns, this planting patterns is utilized the principles of increase yield of crop Edge advantages, by adjusting the line space of rice transplanting, improve ventilation, light transmittance between plant, alleviate disease, increase leaf area index, extend leaf longevity, accelerate dry-matter accumulation, thereby reach the purpose of good quality and high output, cost-saving synergistic.
Wide-narrow row transplanting mechanism is to realize that on the basis that does not change existing rice seedling box of rice seedling transplanting machine structure the rice shoot wide-and narrow-row does not wait the parts of line-spacing plantation.The non-circular cone bevel gear of a kind of high-speed transplanter wide-narrow row transplanting mechanism is disclosed in the document that is CN102640604A at publication number, but the central gear in the document reaches with the idler gear of its engagement and is the cylinder type gear, comprise helical teeth and straight-tooth, jackshaft and central shaft have an angle or are and be arranged in parallel, because this angle is the alternate angle in horizontal plane, therefore, although this angle is conducive to adjust seedling taking point and rice transplanting point, but the seedling pawl attitude adjustment during for seedling taking is unfavorable, easily cause seedling taking inaccurate and touch seedling setting gate; In addition, the interlaced arrangement in horizontal plane due to this transplanting mechanism jackshaft and central shaft, planet axis and jackshaft have an angle of cut in vertical guide, even and if be while being arranged in parallel when jackshaft and central shaft, planet axis and the jackshaft angle of cut in vertical guide will become large, make whole transplanting mechanism spatial volume become large, easy and rice transplanter miscellaneous part is interfered.
Summary of the invention
The purpose of this utility model is to provide and can realizes the straight seedling taking of accurate square, the non-circular cone bevel gear of a kind of high-speed transplanter two-stage wide-narrow row transplanting mechanism that the rice transplanting cave is young, volume is little, simple in structure.
In order to achieve the above object, the technical solution adopted in the utility model is:
At the transmission case internally-powered, by the drive sprocket be arranged on drive sprocket axle, through chain, be delivered on the sprocket wheel of center, the center sprocket wheel is fixed on central shaft, the central shaft two axial ends is fixed with respectively the left and right gear-box that interior is identical, stretches out on the planet axis of outer upper left, lower-left, upper right and bottom right of left and right gear-box upper left, lower-left, upper right and the bottom right transplant arm that structure is identical is housed respectively.
The non-circular cone bevel gear of right heart empty set in the right gear case is at an end of central shaft, by right jaw flange and transmission case, be fixedly connected, the non-circular cone bevel gear of the right heart be packed in bottom right, bottom right on the jackshaft of upper right, in the middle of upper right, non-circular cone bevel gear is meshed, drive and bottom right, coaxial mounted another bottom right of non-circular cone bevel gear in the middle of upper right, in the middle of upper right, non-circular cone bevel gear is rotated, another bottom right, in the middle of upper right non-circular cone bevel gear be packed in bottom right, bottom right on the planet axis of upper right, planet non-circular cone bevel gear in upper right is meshed, bottom right, the end that upper right planet shaft extension goes out the right gear case is fixed with bottom right, the upper right transplant arm, described bottom right, crossed axis angle α between upper right jackshaft and central shaft, bottom right, upper right planet axis and bottom right, crossed axis angle β between the jackshaft of upper right is acute angle, be generally 2～45 degree.
The non-circular cone bevel gear in left and right center in described left and right gear-box case, in the middle of upper left, lower-left, upper right, bottom right in the middle of non-circular cone bevel gear, another upper left, lower-left, upper right, bottom right the relative position in non-circular cone bevel gear and the axle center of upper left, lower-left, upper right, the non-circular cone bevel gear five shaft gear planetary systems of the bottom right planet shape that is in line arrange or become the triangular arrangement about center non-circular cone bevel gear symmetry.
First order travelling gear in described left and right gear-box case is non-circular cone bevel gear in the middle of the non-circular cone bevel gear in left and right center, upper left, lower-left, upper right, bottom right, and second level travelling gear is another upper left, lower-left, upper right, the middle non-circular cone bevel gear in bottom right and upper left, lower-left, upper right, the non-circular cone bevel gear of bottom right planet.
In described left and right gear-box, first order travelling gear and travelling gear position, the second level can exchange, be the left and right center non-circular cone bevel gear location swap in another upper left, lower-left, upper right, the bottom right non-circular cone bevel gear in centre and the first order travelling gear in the travelling gear of the second level, non-circular cone bevel gear location swap in the middle of the upper left in the upper left in the travelling gear of the second level, lower-left, upper right, the non-circular cone bevel gear of bottom right planet and first order travelling gear, lower-left, upper right, bottom right.
The beneficial effect the utlity model has is:
Non-circular cone bevel gear has the non-at the uniform velocity than the space drive characteristic of transmission and bevel gear of non-circular gear concurrently, adopt the non-circular cone Bevel Gear Transmission of two-stage, make the crossed axis angle α of jackshaft and central shaft, crossed axis angle β between planet axis and jackshaft is the acute angle that is not equal to 0 degree, jackshaft and central shaft, planet axis and jackshaft both can be arranged in same vertical guide, also can be not in same vertical guide, therefore, by adjusting jackshaft and central shaft, crossed axis angle α between planet axis and jackshaft, the size of β and relative position, can be so that wide-and narrow-row rice transplanting track and the seedling taking of transplant arm seedling pin, the rice transplanting attitude is more conducive to obtain the straight seedling taking of accurate square, little rice transplanting cave mouth, and it is little to have volume, advantage simple in structure, in addition, in gear-box, first order travelling gear and travelling gear position, the second level can exchange, be another middle non-circular cone bevel gear and the first order travelling gear Zhong center non-circular cone bevel gear location swap in the travelling gear of the second level, centre non-circular cone bevel gear location swap in the non-circular cone bevel gear of planet in the travelling gear of the second level and first order travelling gear, make the installation of transplanting mechanism more convenient.
