Problems solved by technology

[0003] In the early 1980s, Japan had produced orderly rice seedling throwing machinery and entered the market; due to many reasons such as its complex structure, high processing precision requirements, high cost, and low work efficiency, it was not popularized in a large area, accounting for only 20% of the rice planting area. 0.5% or less

Abstract

The invention discloses a coaxial double-bar ejection-type cylindrical gear-elliptical bevel gear planetary system wide-narrow row seedling slinging mechanism. The seedling slinging mechanism comprises a gear box. A central cylindrical gear, upper, lower and middle cylindrical gears, upper, lower and middle elliptical bevel gears and upper and lower planetary elliptical bevel gears are supported in the gear box. Upper and lower transplanting arms are coaxially connected to the upper and lower planetary elliptical bevel gears. A hollow loop bar is slidably arranged in the housing of the transplanting arm. A solid push bar is slidably arranged in the hollow loop bar. A double contour line cam, a shifting fork and a triggering machine are hinged to the interior of the housing of the transplanting arm. The outer end of the hollow loop bar is provided with a seedling taking mechanism. The cylindrical gear-elliptical bevel gear as a transmission mechanism cooperates with the coaxial double-bar ejection-type transplanting arm so that different wide-narrow row seedling slinging agronomic requirements are satisfied and the technical gap of a seedling slinging machine is filled.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to a coaxial double-rod ejection type cylindrical gear-elliptical bevel gear planetary system wide and narrow row seedling throwing mechanism. Background technique [0002] At present, there are three main methods of rice mechanical planting: direct seeding, transplanting and throwing. Among them, direct seeding is a disorderly planting method with a long growth period. Transplanting has a slow seedling period of 5 to 7 days. Both methods will prolong the growth period; however, there is no slow seedling period for throwing seedlings. -15% yield. In addition, seedling throwing has the advantages of fast transplanting speed and no damage to the roots, and is recommended by rice planting experts as the planting technique with the highest yield increase rate. However, disorderly seedling throwing operation is not conducive to later field management, and affects rice ventilation, uniform abso...
