Cross-row traveling wide-narrow row close planting hand-held rice transplanter

Abstract

The invention discloses a cross-row traveling wide-narrow row close planting hand-held rice transplanter, comprising an engine, a ground traveling imitation mechanism, a driving wheel traveling system, a rice transplanting mechanism, a reciprocating mechanism of a rice case, and a hand-held operation system. The distance between the transplanting claws of the rice transplanter is arranged according to the width interval of a wide row and a narrow row. The two transplanting claws in the middle of the rice transplanter form a middle narrow row, a piece of blanket-shape seedlings on the rice case is taken by two crank rocker-type rice transplanting mechanisms at the same time to form the close planted wide-narrow row transplanting, and the crankshafts of the two crank rocker-type rice transplanting mechanisms are connected together. An operator can walk on the two wide rows adjacent to the narrow row in the middle. Due to that the left foot and the right foot of the operator step on the wide rows at the left side and the right side of the middle narrow row, and the traveling by one foot can reduce the width of the traveling row, therefore the close planting wide-narrow row transplanting operation with the larger transplanting density than that of the existing hand-held rice transplanters can be realized.

Description

technical field [0001] The invention relates to a rice planting machine, in particular to a rice transplanter for wide and narrow row dense planting. Background technique [0002] Present walk-behind and high-speed rice transplanter have 30cm and 24cm rice transplanter of equal row spacing, and narrow row is 24cm, wide row is the wide and narrow row rice transplanter of 30cm. The row spacing of these rice transplanters is too wide, and the density of clusters per unit area is too low, which cannot meet the requirements of machine-transplanted sterile lines in hybrid rice seed production. The area of ​​hybrid rice in my country accounts for more than 60% of the total area of ​​rice. Since there is no suitable transplanter for hybrid rice seedlings, the seedlings are basically transplanted by hand. With the transfer of rural labor force and the rise of labor wage costs, there is an urgent need for hybrid rice seed production dense planting rice transplanter. The key to adapti...

Problems solved by technology

In order to reduce the complexity of the rice transplanter, the blanket-shaped seedlings of a seedling tray are designed to be picked up by two claws. However, the two seedling picking mechanisms with wide row spacing are connected to the same transmission box, so that the rice transplanter The two rows of seedlings in the side row need to be specially equipped with a transmission box with only two seedling claws, which actually increases the complexity of the machine

If this design idea is applied to the hand-held rice transplanter for dense planting, the complexity of the transmission mechanism of the hand-held rice transplanter will also be increased.

Also someone has proposed the wide and narrow row rice transplanter that adopts the blanket-shaped seedling of a seedling tray to take seedlings by two seedling claws, but the width of the seedling tray is just twice the distance between the two narrow row seedling claws, and this design will The carpet-like seedlings will not slide smoothly along the seedling tray, which will easily cause seedling leakage
