Transplanting method for horizontal-reciprocating control of rape pot seedlings

Abstract

A transplanting method for horizontal reciprocating control of rape pot seedlings includes: adopting a rape pot seedling horizontal-reciprocating transplanting machine to implement horizontal-reciprocating transplanting; and utilizing a slidable dual gear composed of second-gear and third-gear driving gears, a shifting fork and a first-gear driving gear, wherein the slidable dual gear can be meshed with a third-gear driven gear and a second-gear driven gear to realize a row spacing three-gear adjusting function to meet different planting density requirements; allowing an output shaft of a speed changer to drive a crank to rotate, wherein the crank drives a first crank rocker component and a second crank rocker component to be in horizontal reciprocating motion to reciprocatingly plant therape pot seedlings onto backfilled soil of planting trenches from the horizontal direction to realize horizontal-reciprocating transplanting. A seedling pushing plate in the transplanting machine rotates by a small angle around itself during horizontal seedling pushing to prevent backward seedling throwing and soil throwing during high-speed horizontal transplanting, so that speed and quality of the rape pot seedlings are improved.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a transplanting method for horizontal reciprocating control of rapeseed pot seedlings. Background technique [0002] The cultivation of winter rapeseed in my country is mainly concentrated in the middle and lower reaches of the Yangtze River, and the rice-oil or rice-rice-oil rotation is usually used. Sow in mid-September and harvest in mid-May of the following year. In the middle and lower reaches of the Yangtze River, double-cropping rice is widely planted. The harvesting period of late rice is in early and mid October, and the planting period of early rice is in early and mid-May. Therefore, the method of sowing and planting is difficult to be suitable for rice-rice-oil planting. Mode; using the method of transplanting rapeseed seedlings in pots, rapeseed can be transplanted after the late rice harvest to improve the growth coincidence of the two crops and realiz...

AI Technical Summary

Problems solved by technology

[0003] At present, in the field of pot seedling transplanting of rapeseed, there are mainly transplanting machines such as seedling guide tube type and hanging cup type. Since rapeseed is a high-density planting crop, the planting density is usually about 130,000 plants / ha, and the row and plant distance are small. However, the soil humidity and viscosity of paddy fields in the south are high, and the existing transplanting machine has low working efficiency, which is not suitable for transplanting rapeseed. Horizontal reciprocating transplanting can improve the quality of transplanting. Therefore, how to control the horizontal reciprocating transplanting of rape pot seedlings has become a technology in the art. Technological issues that people need to solve
