【発明の詳細な説明】
本発明は歩行型田植機に関し、詳しくは、マフラーの配
設構造の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a walking rice transplanter, and more particularly to an improvement in the arrangement structure of a muffler.
マフラーは、排気に伴って高温化するため、その熱によ
るエンジン等の他装置への悪影響を回避するべ〈従来一
般に、歩行型田植機では、ボンネット上方やエンジン横
側方に突設されておシ、高温マフラーに不測に接触して
火傷を負う危険があシ、又、マフラーによシ外観的に商
品価値が低下しがちでちった。The temperature of the muffler increases with the exhaust gas, so it is necessary to avoid the adverse effects of the heat on other devices such as the engine. However, there was a risk of injury due to accidental contact with the high-temperature muffler, and the appearance of the muffler tended to reduce its commercial value.
本発明は、上記の点に鑑み、マフラーをエンジン等他装

することにその目的がある。In view of the above-mentioned points, the present invention arranges the muffler inside the bonnet without adversely affecting other devices such as the engine, thereby avoiding the risk of burns, improving the appearance, and improving the product value. Another object of the present invention is to provide a walk-behind rice transplanter that is configured to reduce the influence of exhaust gas from the 77ler on the operator and to cool the muffler well.

成した点にあシ、かかる構成から次の作用効果を奏する
。The characteristic configuration of the walk-behind rice transplanter according to the present invention is as follows: A control knob extends to the rear side of the machine body, and a seedling mounting table and a seedling planting device are provided in front of the handle, the upper end of which is tilted forward. In addition, in a walk-behind rice transplanter having an engine disposed in the front body, an engine cooling air supply device is disposed in front of the engine, and a transmission case is integrally connected to the engine at the rear, and the engine a muffler is disposed in a recessed space located behind the transmission case and above the transmission case, and a muffler is disposed with an exhaust port facing laterally, and a bonnet covers the upper and laterally sides of the engine and muffler; and
A large number of slits are formed in the side portion of the bonnet so that the cooling air from the supply device flows through the surfaces of the engine and the muffler to the slit side. It has an effect.
1 すなわち、歩行型田植機では、伝動系が低い位置に
あるためにエンジンと伝動ケースとで凹入空間が形成さ
れる事、かつ、この事に加えてエンジン冷却風供給装置
によシ凹大空間にエンジン冷苅風が送られている事を有
効利用し、その結果マフラーの熱によるエンジン等の他
装置に悪影響を及ぼす事の無い状態でボンネット内にマ
フラーを配設できるに至り、外部露出に伴う火傷の危険
を回避できると共に、外観が良好になシ、商品価値を向
上できるに至った。1 In other words, in walk-behind rice transplanters, the transmission system is located at a low position, so a concave space is formed between the engine and the transmission case, and in addition to this, a large concave space is created by the engine cooling air supply device. By effectively utilizing the fact that engine cooling air is sent into the space, the muffler can be placed inside the bonnet without having any adverse effects on other equipment such as the engine due to the heat of the muffler, reducing external exposure. In addition to avoiding the risk of burns associated with burns, the product also has a good appearance and can improve its commercial value.
しかも、前記ボンネット内に配置されるマフラーの排気
口は横側方に向けてあシ、かつ、ボンネットの側面部分
に多数のスリットを形成しであるので、77ラーからの
高温排ガスやボンネット内部の熱気は機体の横側方に排
出される。In addition, the exhaust port of the muffler located inside the bonnet is angled toward the sides, and many slits are formed on the sides of the bonnet, so that high-temperature exhaust gas from the 77r and the inside of the bonnet can be removed. Hot air is exhausted to the sides of the aircraft.
従って、一般にボンネット幅よシも左右横方向に幅広く
、かつ、前傾姿勢に構成されている機体後方側の苗載置
台が、前記横側方に排出された排ガスや熱気の後方側へ
の移動を制限してさらに横外側方へ案内することとなシ
、このことから、高温の排ガスや熱気が直接的に苗載置
台上の苗に接触したシ、後方の操縦ハンドルを握る操縦
者に向けられることを極力回避し得たものである。Therefore, the seedling platform at the rear of the aircraft, which is generally wider than the bonnet in both the left and right directions and is tilted forward, prevents the exhaust gas and hot air discharged to the sides from moving to the rear. This means that high-temperature exhaust gas and hot air may come into direct contact with the seedlings on the seedling table, and direct them toward the operator holding the rear control handle. This could have been avoided as much as possible.
