DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a riding type rice transplanter .

[0002]

2. Description of the Related Art Conventional riding type rice transplanters are disclosed in
As disclosed in Japanese Patent No. 4822, a riding step for getting on and off from a ridge or the like to a control section is provided on a lateral side of a hood in a front part of the fuselage, and a muffler is arranged below the riding step. .

[0003]

The exhaust from the muffler is
The operating portion is formed so that the exhaust does not escape upward through the operation pedal insertion hole formed in the riding step in a vertically penetrating state , that is, the exhaust escapes from the operation pedal insertion hole. At the end of the exhaust tailpipe of the muffler, place
In rear of the location, and, since than the front wheels are extended to the rear of the driver's seat near loss deteriorates the exhaust of the engine via line resistance of the exhaust tail pipe, the output of the engine is a disadvantage to decrease, There was also a problem that the mud flipped up by the front wheels easily adhered to the exhaust tailpipe. Therefore,
As a means for solving the above-mentioned drawbacks, it is conceivable to extend the exhaust tailpipe of the muffler laterally outward of the fuselage, and to point the end of the exhaust tailpipe downward. There is a disadvantage that the exhaust air of the sap falls on the adjacent seedlings. An object of the present invention is to eliminate the above disadvantages by a simple structural improvement.

[0004]

According to a first aspect of the present invention, there is provided a riding type rice transplanter having a control section disposed behind an engine bonnet at a front portion of a fuselage, and a control section provided at a lateral side of the engine bonnet. In a riding type rice transplanter in which a riding step is provided over the floor of the section and a muffler is arranged below the riding step, an operation in which an end of an exhaust tailpipe exhausting rearward of the muffler is provided in the riding step. Holes for pedal insertion and
Backward than front perspective opening, and is positioned on the axle upper portion of the front wheel, characterized configure that are.

[0005]

According to the structure of the first aspect, the muffler is directed rearward.
The tail end of the exhaust tailpipe that exhausts air is located behind the hole for the operation pedal provided in the riding step, so that the exhaust from the muffler rises above the hole for the operation pedal as the aircraft travels. Never escape. Further, since the end of the exhaust tailpipe is located above the axle of the front wheel, the length of the exhaust tailpipe is reduced, the pipe resistance is reduced, and the exhaust is more easily removed. Further, the mud splashed by the front wheels hardly reaches above the axle portion of the front wheel and can prevent the mud from adhering to the exhaust tail pipe of the muffler.
Further, since the exhaust gas of the engine is discharged toward the rear of the fuselage, the exhaust gas does not fall on the adjacent seedlings. Since the end of the exhaust tailpipe of the muffler is located behind the front wheel see-through opening formed in the riding step so that the driver can visually check the position of the front wheel from the steering section side , the muffler Exhaust gas does not escape to the steering section above the front wheel see-through opening.

[0006]

As a result of the structure of the first aspect, the exhaust of the muffler can improve the engine output without deteriorating the environment of the control section, and can also suppress the adhesion of mud to the exhaust tail pipe of the muffler. In addition, the exhaust gas does not reach the adjacent planted seedling, and the existing planted seedling is not damaged by the heat of the exhaust gas .

[0007] Further, air is exhausted from the front wheel see-through opening to the steering section.
Since the danger of gas escape is also eliminated, the working environment for the operator in the control section can be further improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A riding rice transplanter according to the present invention will be described below with reference to the drawings. FIGS. 3 and 4 show a riding type rice transplanter. The riding type rice transplanter has an engine bonnet 2 in which an engine 1 is provided at a front portion of the fuselage.
A control section 3 is provided at the rear of the hood 2, and riding steps 4, 4 for getting on and off the control section 3 from ridges and the like are provided on both sides of the hood 2. The riding steps 4 and 4 are shown in FIG.
As shown in FIG. 3 and FIG. 3, the control unit 3 is provided so as to be continuous with the floor.

As shown in FIG. 2, the engine 1 has a horizontal axis.
In the forced air cooling type, an intake port 2a for the engine cooling air is provided on the right side of the bonnet 2, and after cooling the upper cylinder head, it is discharged to the left outlet port 2b side. Further, the grill 2c provided at the cooling air discharge port 2b is formed in a curved cross-sectional shape for guiding the engine cooling air downward, thereby suppressing the engine cooling air from hitting the operator walking on the riding step 4. It is configured to do so.

On the left side of the engine 1, an exhaust pipe 5 and a muffler 6 following the exhaust pipe 5, and a belt continuously variable transmission 7 for transmitting the output of the engine 1 to a traveling mission M
The engine bonnet 2 is provided so as to cover the engine 1 and the belt continuously variable transmission 7.

The muffler 6 is disposed below the left riding step 4, and an end of an exhaust tail pipe 6a of the muffler 6 is provided at the riding step 4 so that the exhaust of the engine does not reach the operator. As shown in FIG. 4, the front wheels 9 are located behind the front wheel see-through openings 4 a, 4 a and the hole 8 a for inserting the clutch operation pedal 8.
Is located above the axle 9a. Further, the exhaust tail pipe 6a of the muffler 6 is bent to the inside of the body avoiding the front wheel 9 in a plan view, and is bent along the outer periphery of the front wheel 9 in a side view. The end is slightly diagonally downward.

In the claims, reference numerals are provided for convenience of comparison with the drawings, but the present invention is not limited to the configuration shown in the accompanying drawings.
