Abstract
Description
本発明は例えば苗載台及び植付爪を備えて連続的に苗植作業を行う田植機に関する。 The present invention relates to a rice transplanter that continuously performs seedling planting operations, for example, including a seedling mounting table and planting claws.
従来、走行車にミッドマウント型の施肥機を取付ける技術がある。(例えば、特許文献1参照) Conventionally, there is a technology of attaching a mid-mount type fertilizer to a traveling vehicle. (For example, see Patent Document 1)
前記従来技術は、走行車側の肥料繰出ケース出口を植付部側の側条施肥シュートに接続させる搬送ホースを設けていたが、植付部の昇降に必要な長さに搬送ホースを長くすると、該ホース中間部が自重で下方に折曲がり、前記ホースが下方の後輪に接触したり、前記シュート出口からホースが外れる等の不具合があると共に、環状ガイドに前記ホース中間を挿通させてホースの折曲がりを防ぐと、ホースの上方向の折曲げが制限されたり、ホース曲げ力によってガイドが変形するから、植付部上昇時などにホースが揺振して無理に曲げられ易く、ガイドが損傷したりホースの支持が不適正になる等の不具合がある。また、6条植え等の多条植付部では植付条数と同数の搬送ホースが苗載台裏面側に延設され、苗載台裏面側での前記ホースの固定を容易に行い得ない等の問題があった。また、植付部の昇降によって前記搬送ホース中間が左右方向に折れて横倒れ状態となり、隣接の植付深さ調節レバーなどに前記ホースが引掛り易い等の不具合があった。 In the prior art, the transfer hose that connects the fertilizer feeding case outlet on the traveling vehicle side to the lateral fertilizer chute on the planting section is provided.However, when the transfer hose is lengthened to a length necessary for elevating and lowering the planting section. In addition, the hose middle part is bent downward by its own weight, the hose comes into contact with the lower rear wheel, the hose comes off from the chute outlet, and the like. If the bend of the hose is prevented, the upward bending of the hose will be restricted and the guide will be deformed by the hose bending force. There are problems such as damage and improper hose support. Also, in a multiple-row planting section such as a six-row planting, the same number of transfer hoses as the number of planting strips are provided on the back side of the seedling mounting base, and the hose cannot be easily fixed on the back side of the seedling mounting base. And so on. In addition, as the planting section is moved up and down, the intermediate portion of the transfer hose is bent in the left-right direction to be in a sideways position, and there is a problem that the hose is easily hooked on an adjacent planting depth adjusting lever or the like.
然るに、本発明は、請求項1の如く、肥料を入れる施肥ホッパと、該ホッパの肥料を送出させる多条用の肥料繰出ケースと、前記ケースの肥料送出部に送風を供給するエアタンクと、エアタンク一側に設ける送風機を備える田植機において、前記肥料繰出ケースの出口に接続させる搬送ホースの折曲がりを規制するホースガイド体を前記エアタンクよりも後方に設けることを特徴とする。 Therefore, the present invention provides a fertilizer application hopper for adding fertilizer, a multi-row fertilizer feeding case for feeding the fertilizer of the hopper, an air tank for supplying air to a fertilizer sending section of the case, and an air tank. In a rice transplanter provided with a blower provided on one side, a hose guide body for restricting bending of a transfer hose connected to an outlet of the fertilizer feeding case is provided behind the air tank.
また、請求項2の如く、肥料繰出ケースの出口を側条施肥シュートに接続させる搬送ホースの下面方向の折曲がりを規制するホースガイド体を設け、また前記肥料繰出ケースの出口を側条施肥シュートに接続させる多条用の各搬送ホース中間を係止させるホースガイドフレームを設け、苗載台裏面の左右苗台支柱に前記ホースガイドフレームを固定させ、側条施肥シュート近傍の搬送ホースを取付ける支持部材を設け、前記エアタンクよりも後方でホースガイド体を固定させ、エアタンクの後側に設ける搬送ホースのジョイント近くでホースガイド体によって搬送ホースを支持させることを特徴とする。
