JP2002326795A - Muffler device of fork lift truck - Google Patents

Abstract

PROBLEM TO BE SOLVED: To eliminate such problems in a conventional structure that a muffler itself is heated to a high temperature by a heat generated in a muffler and, when an operator touches the muffler, he gets burned, or the operator gets hot wind in running backward and, though the muffler is covered, the cover is heated due to a rise in temperature inside the cover and, when the operator touches the cover, he may get burned or steam may smoke in rainy days. SOLUTION: In this muffler device of a fork lift truck, an opening part 18 is provided in either of a radiator cover 8 positioned at the rear upper part of a radiator 13, a muffler mounting plate 2, and a weight 1, a part of air from a cooling fan 14 after cooling the radiator 13 is led into the muffler cover 6 to lower the temperature of the muffler 5.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a muffler device for a forklift.

[0002]

2. Description of the Related Art In recent years, mufflers have become large in size due to environmental problems due to a structure incorporating functions such as black smoke removal and exhaust gas purification, and cannot be accommodated in a weight by the conventional technology, as shown in FIGS. A muffler is mounted on the upper part of the weight, and the inlet pipes b and d are connected from the exhaust manifold of the engine through through holes in the radiator cover c.

[0003]

However, in the above-mentioned conventional structure, there is a problem that the heat generated by the muffler causes the muffler itself to be heated to a high temperature. The cover a is heated by the rise in temperature inside the cover a, and there is a risk that the cover a may be burned when touched by hand, and there is a problem that steam rises on a rainy day. It is an object of the present invention to eliminate such disadvantages.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and has an opening formed in a radiator cover, a muffler mounting plate, or a weight located above a rear portion of a radiator. A muffler device for a forklift, wherein a part of the cooling fan that cools the radiator is taken into the muffler cover through the opening to lower the temperature of the muffler cover.

[0005] With the above structure, the inside of the muffler cover can be cooled to prevent the cover from becoming hot, and by selecting the muffler tail pipe, the user can be directed upward or in the weight. Can easily be met.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described.
This will be described with reference to the drawings. FIG. 1 is an arrangement sectional view of a muffler device of a forklift according to the present invention, FIG. 2 is an exploded perspective view,
FIG. 3 is a top view.

Referring to FIG. 1, a muffler mounting plate 2 is mounted on a weight 1 with mounting bolts 3, and a muffler 5 is mounted on the muffler mounting plate 2 via a mounting bracket 4.

The muffler mounting plate 2 is provided with a concave portion at the end to form an opening 18, and a part of the wind of the fan 14 that has cooled the radiator 13
It has been adopted from.

The inlet pipe 7 connected to the muffler 5 is connected in combination with the inlet pipe 9, and is connected to the muffler 5 from the exhaust manifold of the engine through the opening 18 of the muffler mounting plate 2. The opening 18 is provided in addition to the mounting plate 2.
It may be provided on the radiator cover 8 or the weight 1.

The radiator cover 8 is supported on an upper portion of the plate 22 of the muffler mounting plate 2, and the muffler cover 6 is mounted on the plate 2 of the muffler mounting plate 2.
1 can be attached. The left and right three side surfaces of the muffler cover 6 are opened using expanded metal or the like, so that the cooling air of the muffler 5 introduced from the opening 18 of the muffler mounting plate 2 is discharged.

By adopting such an arrangement structure of the muffler 5, the high heat generated by the muffler 5 can be reduced by using the wind of the cooling fan 14 taken in from the opening 18, and the inside of the muffler cover 6 does not become hot. The operator does not inadvertently touch the muffler cover 6 and burns, and there is no problem such as steam rising on a rainy day.

The tail pipe 10 shown in FIG. 1 is attached to the muffler 5 on one side and passes through the opening 18 of the muffler attachment plate 2 to exhaust the exhaust from the inside of the weight 1. At the request of the user, by mounting another tail pipe 101 shown in FIG. 2 instead of the tail pipe 10, the exhaust can be easily replaced so as to be discharged from the upper part of the weight 1.
