〔産業上の利用分野〕
この発明は、田植機や湛水播種機等の水田用農作業機に
装着される接地フロートに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a grounding float that is attached to a rice field agricultural machine such as a rice transplanter or a water seeder.
従来の接地フロートは、フロートを接地させたままで旋
回するときにフロートが泥水を押寄せないように接地フ
ロートの前後中間部分の裏面を上方へ凹ませて泥水が接
地フロートの左右側に通過できるよう構成したものはあ
った。In conventional grounding floats, when turning with the float on the ground, the back surface of the front and rear intermediate parts of the grounding float is concave upward to prevent the float from pushing muddy water, allowing muddy water to pass to the left and right sides of the grounding float. There was something configured.
従来構造の接地フロートでは、接地面積が少なくなり、
水田の表土面が軟らかいときは接地フロートが沈込んで
十分な機体支持力が得られない欠点があるばかりでなく
、整地性能が悪くなる問題点を有していた。With conventionally structured grounded floats, the grounding area is small,
When the topsoil of the paddy field is soft, the ground float sinks, making it impossible to provide sufficient support for the aircraft, and it also has the problem of poor ground leveling performance.

中に没している。In the upper configuration, during seedling planting, the bottom surface of H and D slides in contact with the topsoil surface (A) of the paddy field, and the depth of water on the topsoil surface (A) is A. The front part (B) and the rear part (C) of the grounding float head/QD protrude from the "-" surface of , ), but the front and rear middle part (A) is submerged in the water lower than the water surface (U).
このため、旋回するときは、接地フローＩＪＩ・ＱＤを

うな事典を防止できる。Therefore, when turning, even if the ground contact flow IJI/QD remains in contact with the topsoil surface (A), the muddy water will cover the upper surface of the front and rear intermediate part (A) of the ground contact float (1)/al). It can pass through and turn smoothly without pushing the mud outward, which prevents already planted seedlings from being pushed over by the muddy water.

When + moves the tiller (D is deep), the hydraulic switching pulp OQ is switched to project the piston θ''h and move the water wheel (6) downward.On the contrary, the tiller (C) When the float is shallow, the float 0υ moves downward, and the valve H moves upward so that the piston 0'h retracts, causing the paddy wheel (6) to move.In this way, the paddy wheel (6) moves up and down the ground float. However, in rice transplanters and flooded I-type machines with such a configuration, if the front and rear middle parts of the ground float are low and submerged in water, the vertical movement of the ground float will be stabilized, and the rice paddy wheels will be controlled vertically. (6) Vertical control becomes stable.

ピストン０２を突出ならしめている。Figures 6 to 8 show a pair of left and right paddy wheels (c) and (e).
This is an example of a towing vehicle body when propelling a rice field with a
Traveling mission case A pair of chain cases on the left and right sides of the plow are pivotally connected to allow vertical movement, and paddy wheels (c) and (1) are supported on both left and right sides of the rear end. (To) is a hydraulic system, and a piston 02 is made to protrude from the rear end of a hydraulic cylinder 0 installed at the middle of the left and right.
