Rice transplanter

Abstract

A rice transplanter (1) provided with a planting unit (4) that includes a center float (14A) that detects a surface in contact with a field (G). Said rice transplanter (1) is also provided with a sensor (20) that is separate from the center float (14A) and detects the position of the surface of the field (G). A detection unit (21) in said sensor (20) is positioned to the side of the center float (14A) and immediately in front of a planting position (P). Thus positioned, the sensor (20) can detect the position of the surface of the field (G) accurately, improving the precision with which seedlings are planted.

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...

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
