Description
Technical field
The present invention relates to a kind of rice transplanting machinery, especially relate to the capable transplanting mechanism of a kind of face gear transmission width.
Background technology
The paddy rice wide-narrow row planting, be narrow row apart from the rice high yield planting technology of cultivating at interval with wide line-spacing, this planting patterns is utilized the volume increase principle of crop limit advantage, by adjusting the line space of rice transplanting, improve ventilation, light transmittance between plant, alleviate disease, increase leaf area index, prolong leaf longevity, accelerate dry-matter accumulation, thereby reach the purpose of good quality and high output, cost-saving synergistic.
Transplanting mechanism is to realize seedling taking on the rice transplanter, implant Tanaka, make the core work parts of rice shoot succeeding planting.At present no matter the rice transplanter of selling on the market at home is crank rod-type transplanting mechanism, and what rotate still that transplanting mechanism all realizes is to wait line-spacing rice transplanting operation, and namely transplanting mechanism seedling pin working face moves in the plane parallel with transmission case.In order to adapt to the agriculture requirement that the paddy rice wide-narrow row planting can improve output, a kind of energy of patented invention of the present invention is fit to the rice transplanter transplanting mechanism of the capable operation of width, the drive mechanism of transmission case has two kinds of forms: the one, the face gear drive: adopt a cover externally-engaged cylindrical gear mechanism, face gear transmission mechanism make transplanting mechanism seedling taking with push away seedling seedling pin constantly not on the same plane vertical with sprocket shaft, make transplant arm with the plane of sprocket shaft inclination certain angle in move; The 2nd, the crown gear transmission: adopt a cover crown gear and bevel gear engagement transmission mechanism make transplanting mechanism at seedling taking and the seedling pin that pushes away the seedling moment not on the same plane vertical with sprocket shaft, make transplant arm with the plane of sprocket shaft inclination certain angle in move.
After above-mentioned two kinds of drive mechanism seedling takings, transplant arm seedling pawl is because the inclination of gear-box produces the lateral movement of forward direction, make the rice shoot relative seedling taking position certain distance of skew that moves to left or move to right of burying a little, thereby the line-spacing of institute's rice transplanting seedling is changed, satisfy the capable rice transplanting of width of agriculture requirement.
Summary of the invention
