Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tractor tail pipe.

[0002]

2. Description of the Related Art Since the bonnet covers just above the engine, the tail pipe of the muffler is also likely to project upward from the bonnet. Therefore, in the form in which the tail pipe stands above the bonnet, opening and closing of the bonnet is likely to be an obstacle.

[0003]

The present invention provides an engine E
Further, a bonnet 2 which covers the muffler 1 and can be opened and closed is provided with a bonnet port 4 through which the muffler pipe 3 having the discharge port of the muffler 1 can be seen. The muffler pipe 3 has a tail pipe cover 5 on the outer periphery. The tail pipe 6 is a tractor tail pipe in which the tail pipe 6 is removably fitted from the upper side of the bonnet port 4.

[0004]

When the hood 2 is opened and closed, the tail pipe cover 5 is held and the tail pipe 6 is pulled out upward from the muffler pipe 3. Tail pipe 3
When is removed, there is no obstruction on the bonnet mouth 4,
The hood 2 can be opened and closed. Tail pipe 6
Since the exhaust from the muffler pipe 3 of the muffler 1 is ejected from the upper end of the tail pipe 6 when it is attached, it can be exhausted to a height away from the upper surface of the bonnet 2. Since the pipe cover 5 can be gripped, the bonnet 2
When the tail pipe 6 is heated, the tail pipe 6 can be easily attached and detached.

[Example] A tractor body 7 has a steering handle 8
It has a front wheel 9 and a rear wheel 10 which can be steered, and is in a four-wheel drive traveling mode driven by an engine E mounted on the front part. 11 is a handle post, 12 is a cockpit,
13 is a fender and 14 is a dashboard. The engine E has a radiator 15 on the front side and a muffler 1 on the upper side of one side. The bonnet 2 that covers the upper part of the engine E can be opened and closed by rotating the front lower part on the bracket of the front end of the vehicle body 7 back and forth around the open / close pin 16.

A muffler pipe 3 is provided at the discharge port of the muffler 1 so as to be directed upward, at a height slightly higher than that of the bonnet 2 at the time of closing, and the upper end port of the muffler pipe 3 is the bonnet port of the bonnet 2. The relationship is set to project from 4. At this time, an appropriate space is formed between the peripheral edge of the bonnet port 4 and the peripheral surface of the muffler pipe 3.
Further, the muffler pipe 3 and the peripheral edge of the bonnet opening 4 are set so as not to come into contact with each other even if the bonnet 2 is rotated upward around the opening / closing pin 16.

A cam pipe 17 having a large diameter is provided at the lower end of the muffler pipe 3, and a cam surface 18 formed at the upper and lower cut edges is provided at the upper end edge so that the tail pipe 6 can be oriented by the cam surface 18. regulate. The tail pipe 6 can be fitted into the muffler pipe 3 at its lower end from the upper side, and is freely rotatable. The lower edge 19 formed on the inclined edge is received by the cam surface 18 and the discharge port 20 at the upper end. Restrict the direction to the front. Further, the tail pipe 6 can be freely inserted and removed from the bonnet port 4, and the tail pipe cover 5 is attached to a portion located on the bonnet 2 in a state where the tail pipe 6 is connected to and attached to the muffler pipe 3.

The tail pipe cover 5 is split symmetrically with respect to the tail pipe 6 and has a constant space 23 from the peripheral surface of the tail pipe 6 so that heat cannot be easily transferred. The tail pipe cover 5 is fixed to a side wall of the tail pipe 6 by a bolt 22 and fixed to a bracket 21 which is integral with the tail pipe 6, so that the tail pipe cover 5 can be attached to and removed from the muffler pipe 3 through the bonnet port 4.
