Wide and narrow row spacing type rice transplanter

Abstract

The invention provides a wide and narrow row spacing type rice transplanter capable of planting rice with wide and narrow row spacings. The wide and narrow row spacing type rice transplanter comprises seedling boxes, left and right transplanting mechanisms, seedling box moving mechanisms and a rear suspension rack connected with a power running device; the seedling boxes can horizontally move left and right on the rear suspension rack under the rotation of the seedling box moving mechanisms; the spacings among seedling taking and transplanting mechanisms in the same group are the width of the wide row, and the spacings among seedling taking and transplanting mechanisms of different groups of transplanting mechanisms are the width of the narrow row, and wide rows and the narrow rows are arranged at intervals; the seedling boxes are separated into a plurality of equal seedling placing units; units are separated by groove-shaped plates, and the widths of the groove-shaped plates of the adjacent seedling placing units are not equal, namely, the wide groove-shaped plates correspond to the wide rows, and the narrow groove-shaped plates correspond to the narrow rows, so that under the same transplanting stroke, seedlings form an alternant wide and narrow row transplanting mode.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to the field of rice transplanting machines with wide and narrow rows. Background technique [0002] Wide and narrow row transplanting means that the row spacing of the rice transplanter is implemented in one wide and one narrow transplanting method. This transplanting method utilizes the principle of crop marginal advantage to increase production. Area index, prolong leaf life, so as to achieve the purpose of high and stable rice yield. [0003] Existing wide and narrow row rice transplanter mainly contains two kinds of modes. One, as disclosed in the document of CN 101779540 A (wide and narrow row rice transplanter) in the application publication number, the narrow row is half of the wide row, and the shortcoming of this wide and narrow row rice transplanter is: the rice seedling of transplanting The density is more than twice that of ordinary rice transplanters. Too dense seedlings ...

AI Technical Summary

Problems solved by technology

One, as disclosed in the document of CN 101779540 A (wide and narrow row rice transplanter) in the application publication number, the narrow row is half of the wide row, and the shortcoming of this wide and narrow row rice transplanter is: the rice seedling of transplanting The density is more than twice that of ordinary rice transplanters

The disadvantage of this method is that the process is more complicated, and due to design reasons, the width of the wide row of the wide and narrow row transplanting device is the width of the seedling tray plus twice the offset distance of moving left or right, and the width of the narrow row It is the width of the seedling tray minus twice the offset distance of moving left or right

The rice transplanting density of this wide and narrow row transplanting device is not much higher than that of conventional rice transplanting machines, so the ability to increase rice production is limited
