Description
Technical field
The invention belongs to agricultural machinery technological field, relate to the transplanting mechanism of high speed corn wide-and narrow-row transplanter, be specifically related to the oblique zigzag transplanting mechanism of a kind of three non-conical gear planet circular system corn wide-and narrow-rows.
Background technology
China has a large population in a small area, and transplanting can take full advantage of land resources, and the transplanting of land for growing field crops cereal crops particularly is badly in need of, and the corn potted-seedling transplanting is the important measures that improve corn yield, can improve output 15～20%.In addition, the corn potted-seedling transplanting can solve the large tracts of land problem of being short of seedling after planting in northern spring drought days.But the current transplanter of international market, complex structure, cost is too high, efficiency is low, and cheap cereal crops are transplanted and are difficult to bear, thereby exploitation is efficient, full-automatic corn transplanter at a low price, becomes the task of top priority.
Wide-narrow row planting refers to that between maize seedling, row are carried out one wide one narrow planting patterns to spacing, this planting patterns is utilized the principles of increase yield of crop Edge advantages, by adjusting between maize seedling, be listed as to spacing, improve ventilation, light transmittance between plant, alleviate disease, thereby reach the purpose of good quality and high output, cost-saving synergistic.
Wide-narrow row planting can change between maize seedling row to spacing, but in each row between adjacent maize seedling distance equate, so ventilate between plant, light transmittance can also further improve.
Summary of the invention
The objective of the invention is for the deficiencies in the prior art, provide a kind of three non-conical gear planet circular system corn wide-and narrow-rows oblique zigzag transplanting mechanism, realize the requirement of the oblique zigzag plantation of maize seedling wide-and narrow-row, by regulating the axis angle between central shaft and jackshaft and planet axis and jackshaft, optimize the associated mechanisms parameter, can design the oblique zigzag transplanting mechanism of three non-conical gear planet circular system corn wide-and narrow-rows that meets different type of machines, different wide-and narrow-row agriculture requirements.This is significant to improving corn yield.
The combination that the corn planting that the present invention realizes is wide-narrow row planting and the plantation of oblique zigzag.Described oblique zigzag plantation for plantation after along the transplanting mechanism direction of advance, between the maize seedling of the maize seedling of maize seedling, colleague's adjacent columns, the maize seedling of same column adjacent lines and adjacent columns adjacent lines, the order line is oblique zigzag.
The present invention includes power-transmitting part, jaw flange and the parts of planting; Two parts of planting are separately positioned on the both sides of power-transmitting part.
Described power-transmitting part comprises center sprocket wheel, central shaft, drive sprocket axle, drive sprocket, chain and transmission case; Center sprocket wheel, central shaft, drive sprocket axle, drive sprocket and chain whole installation are in transmission case; Drive sprocket axle and drive sprocket are arranged on the afterbody of transmission case, and the two ends of drive sprocket axle all are connected with transmission case by bearing, and drive sprocket is fixedly installed on the middle part of drive sprocket axle; Center sprocket wheel and central shaft are arranged on the head of transmission case, between central shaft and transmission case, by bearing, are connected, and the middle part that transmission case Wai， center sprocket wheel is fixedly installed on central shaft is all stretched out at the two ends of central shaft; Between center sprocket wheel and drive sprocket, by chain, be connected.
The described parts of planting comprise center bevel gear, jackshaft, Intermediate bevel gears, transplanting arm, planet axis, bevel planet gear and gear-box.
