Problems solved by technology

[0004] For example, depending on the condition of the field, the hull of the rice transplanter sometimes sinks into the field, which reduces the accuracy of detection of the position of the hull of the rice transplanter on the surface of the field

Embodiment Construction

[0040] Such as figure 1 As shown, the rice transplanter 1 is provided with the engine 2, the power transmission part 3, the planting part 4, and the elevating part 5. The planting unit 4 is connected to the machine body via the lifting unit 5 , and can be raised and lowered in the vertical direction by the lifting unit 5 . Power from the engine 2 is transmitted to the planting unit 4 via the power transmission unit 3 . The rice transplanter 1 plants rice seedlings in the field G through the planting unit 4 while traveling by the driving of the engine 2 .

[0041] In this embodiment, a case where seedlings are planted at a predetermined planting depth from the surface of the field G in a state where the field G is covered with field surface water W will be described. In addition, the same technical idea can be applied to the planting work in the state where the field G is not covered with the field surface water W.

[0042] The driving force from the engine 2 is transmitted ...

Abstract

The rice transplanter (1) of the present invention is provided with a planting part (4) including a central rice transplanter hull (14A), and the central rice transplanter hull (14A) detects a ground contact surface in contact with a field (G), and the rice transplanter (1) Equipped with a sensor (20) that is installed independently of the central rice transplanter hull (14A) for detecting the surface position of the field (G), and the detection part (21) of the sensor (20) is arranged on the central rice transplanter hull (14A) ) and directly in front of the planting position (P). The sensor (20) arranged in this way can accurately detect the surface position of the field (G), thereby improving the planting accuracy of the seedlings.

Description

technical field [0001] The present invention relates to a rice transplanter provided with a rice transplanter hull for detecting the position of a field surface serving as a ground contact surface in contact with a field. Background technique [0002] In Japanese Patent Application Laid-Open No. 2002-125423, a rice transplanter is disclosed, in which a sensor arm is provided in a groove at the lower part of the hull of the rice transplanter, and the hardness of the field is detected by detecting the rotation angle of the sensor arm, and based on the hardness, Controls the rotation speed of the ground preparation rotor. [0003] In order to improve the planting accuracy of seedlings, more accurate detection of the hardness and height (surface position) of the field is required. [0004] For example, depending on the condition of the field, the hull of the rice transplanter may sink into the field, and the accuracy of detection of the position of the hull of the rice transpla...
