Seedling transplanter

Abstract

The present invention provides a seedling planter in which two or more seedling-planting members are laterally disposed to plant seedlings in two or more rows and which can properly plant the right and left seedlings, even when the surface of a field (the upper surfaces of ridges) are not horizontal. This seedling planter, in which two or more seedling planting members 20 vertically moved with a vertically moving mechanism 21 in a prescribed operation track to plant the seedling in the field are disposed and in which soil-covering press wheels 37 are disposed behind the seedling planting members 20, comprises a lateral inclination sensor for detecting a lateral height difference of the surface of the planting field based on the height difference between the right and left soil-covering press wheels 37, and a control mechanism for controlling the heights of the seedling planting members 20 on the right and left outermost sides from the surface of the planting field on the basis of the detected lateral height difference of the planting field surface with the lateral inclination sensor.

Description

technical field [0001] The technical field of the present invention is a seedling planting machine which arranges more than two seedling bodies left and right and plants more than two seedlings. Background technique [0002] Conventionally, there is a seedling planting machine that detects the left and right inclination of the body with a level sensor and controls the body to be horizontal in the left and right directions to perform seedling planting work (Patent Document 1: Japanese Patent Application Laid-Open No. 2002-46661). [0003] The existing device uses a level sensor to detect the left and right inclination of the body and controls the body to be horizontal in the left and right directions to perform seedling planting operations. , can carry out transplanting operation of seedling well, but it is difficult to flatten into level, and as the mode of ridge, in order to drain well, mostly the ridge is made into a semi-conical shape (the ridge is made into a gentle curv...

AI Technical Summary

Problems solved by technology

[0003] The existing device uses a level sensor to detect the left and right inclination of the body and controls the body to be horizontal in the left and right directions to perform seedling planting operations. , can carry out transplanting operation of seedling well, but it is difficult to flatten into level, and as the mode of ridge, in order to drain well, mostly the ridge is made into a semi-conical shape (the ridge is made into a gentle curved surface shape) ) in more cases

[0004] In this way, if the farmland surface (on the ridge) is not horizontal, then in a seedling planter that arranges more than two seedling bodies on the left and right and plants more than two seedlings, if the horizontal sensor is used to detect the left and right inclination of the body and control it to make the body If the seedlings are planted horizontally in the left and right directions, the depths of the left and right seedlings will be different, and in the worst case, the outermost seedlings cannot be planted.
