ダルを配設してある乗用型田植機に関する。[Detailed description of the invention] This invention places the engine and transmission case equipped with a cooling fan at the front of the aircraft in front of the driver's seat, and the seedling planting device can be raised and lowered at the rear of the passenger car body. The present invention relates to a riding rice transplanter that is connected to a vehicle and has an operating pedal located in front of the driver's seat.

た。 The conventional rear-mounted riding rice transplanter, which has a seedling planting device connected to the rear of the vehicle body, has an engine at the front of the machine body, and front and rear wheels, as shown in the technology disclosed in Japanese Utility Model Application Publication No. 56-73931. In between the mission case,
It consisted of a driver's seat at the rear upper part of the transmission case, and a seedling planting device connected to the rear of the vehicle body that included the engine, transmission case, and driver's seat.
このような構造のものによれば、湿田走行中に
おける後輪側の大きな駆動反力に起因した前輪の
浮き上がりを阻止する為に、車体の前部に大きな
バランスウエイトを設けなければならないという
不都合があつた。 With this structure, there is the inconvenience that a large balance weight must be installed at the front of the vehicle body in order to prevent the front wheels from lifting due to the large drive reaction force on the rear wheels while driving in wet fields. It was hot.

輪が浮き上がり気味となり、これを避ける為に
は、車体の前部に大きなバランスウエイトを設け
なければならないという不都合があつた。 In other words, because rice transplanters run with their wheels immersed in mud, the driving reaction force of the wheels is large.Moreover, according to the rear-mounted riding rice transplanter, which has a seedling planting device connected to the rear of the vehicle, it is difficult to seed seedlings. Due to the weight of the planting equipment and seedlings, the center of gravity of the machine tends to move toward the rear, causing the front wheels to tend to lift up, and to avoid this, a large balance weight must be installed at the front of the vehicle, which is an inconvenience. Ta.
ところが、このように、車体の前部に大きなバ
ランスウエイトを設ける場合には、機体の軽量化
が望ましい田植機にとつて機体の重量が増大し、
それに伴つて、エンジンを大型化しなければなら
ないという不都合があつた。 However, when a large balance weight is installed at the front of the machine, the weight of the machine increases, even though it is desirable for the machine to be lightweight.
Along with this, there was the inconvenience that the engine had to be made larger.
本考案の目的は、機体の重量増加を招くこと少

ようにする点にある。 The purpose of this invention is to suppress the lifting of the front wheels without increasing the weight of the aircraft, and, through simple modification, to create a system that does not cause discomfort to seated workers and makes it difficult to operate the pedals. The aim is to further reduce the front and rear width of the aircraft without causing any problems, and to make it easier to get on and off from the ridge.

前記エンジン及びミツシヨンケースに対して機体
前後方向で重複すべく配置した点にあり、斯かる
構成から次の作用効果を奏する。 The characteristic configuration of this invention to achieve the above purpose is as follows:
An engine equipped with a cooling fan and a transmission case are arranged vertically and overlappingly in a state in which the engine is positioned forward of the front wheel axle and above the transmission case, The air blowing direction is set so that the cooling air is blown toward the front of the aircraft body, and furthermore, the operator's footrest step is extended to near the front end of the engine, and the operation pedals are overlapped above and below the engine. On the footrest step on the side of the engine and transmission case, and when viewed from the side,
The engine and transmission case are arranged so as to overlap with each other in the longitudinal direction of the aircraft body, and this configuration provides the following effects.
すなわち、前輪の車軸よりも前方にエンジンと

反力並びに苗植付装置に対するバランスウエイト
代わりに利用することができ、これによつて車体
前部に設けられる別途専用のバランスウエイトを
小さくして、機体の重量増加を大きく招くことな
く前輪の浮き上がりを阻止することができる。 In other words, since the engine and transmission case are placed ahead of the front wheel axle, not only the engine but also the transmission case can be used as a balance weight for the drive reaction force of the wheels and the seedling planting device. This makes it possible to reduce the size of the separately dedicated balance weight provided at the front of the vehicle body and prevent the front wheels from lifting up without significantly increasing the weight of the vehicle body.
そして、前記エンジンとミツシヨンケースとを
上下に重複配置してあるから、前輪の車軸よりも
前方位置でエンジンとミツシヨンケースとを前後
に配設する場合に比して、前輪からの機体突出長
さが小となり、機体旋回半径を小さくできて、畦
際における枕地植えを少なくできる利点がある。 Since the engine and the transmission case are arranged vertically and overlappingly, the body protrudes from the front wheels, compared to a case where the engine and the transmission case are arranged in front of each other at a position forward of the axle of the front wheels. The advantage is that the length is small, the turning radius of the aircraft can be made small, and the amount of headland planting at the edge of the ridge can be reduced.

席を着座作業者に不快感を与えることのない状態
で、且つ、ペダルの操作が行い難くなることのな
い状態で前後巾小に設けることによつて、機体前
後巾の短縮化を図ることができる。 Since the engine cooling air is blown toward the front of the aircraft, it is possible to prevent the cooling air from blowing onto the seated worker even if the engine and the driver's seat are placed close to each other.
In a structure in which engine cooling air is blown toward the rear of the aircraft, a separate barrier wall must be provided to prevent the hot air from blowing onto the operator after the engine has been cooled. This has the advantage of preventing hot air from blowing onto the worker after the engine has been cooled. Furthermore, since the operating pedals are placed on the sides of the engine and transmission cases, which are arranged overlappingly above and below, the operation pedals can be moved between the driver's seat, the engine and the transmission case without causing the inconvenience of difficulty in operating the pedals. As a result, the engine, transmission case, and driver's seat can be placed as close together as possible without causing discomfort to the worker seated in the driver's seat, while making it difficult to operate the pedals. By providing the front and rear widths in a small state without causing problems, the front and rear width of the fuselage can be shortened.
さらにまた、操縦者の足載せステツプを、エン

端を畦に近づけることによつて、田圃の中に足を
踏み入れることなく、畦から乗降することができ
る利点がある。 Furthermore, since the operator's footrest extends to near the front end of the engine, by bringing the front end of the aircraft closer to the ridge, it is possible to get on and off from the ridge without stepping into the rice field. There are advantages that can be achieved.
