Description

[Detailed Description of the Invention] The present invention relates to the structure of a cover that covers the side surface of an engine section with a muffler conduit inserted therethrough.

In the conventional cover structure on the side of the engine part, the insertion hole for the muffler conduit was formed in the cover in a penetrating state, so when the cover was removed for maintenance, inspection, etc. of the engine part, the muffler conduit was also removed at the same time. removal,
In addition, the cover must be attached, and removing the cover requires a lot of effort and is inconvenient.

In view of these points, the present invention makes it possible to easily remove the cover for maintenance and inspection of the engine section, and at the same time solves problems related to the strength of the cover. Have a purpose in what you are trying to do.

That is, the cover structure for the side surface of the engine part according to the present invention forms a notch large enough to insert the muffler conduit in the upper part of the cover that covers the side face of the engine part, and also forms a notch part large enough to pass the muffler conduit through the cover. Since the feature is that there is a connecting piece that connects the opposite ends of both ends of the notch, even when the cover is removed for maintenance or inspection of the engine, the muffler can be removed as described above. There is no need to separately collect the conduit, and the cover can be easily removed during maintenance or inspection of the engine section.

Moreover, by reinforcing the reduction in strength of the cover that occurs due to the formation of such a notch with a connecting piece provided across the opposite sides of this notch, the mechanical strength required when attaching the cover is increased. We have now been able to secure a sufficient amount of

In addition, when the connecting piece is configured to be able to swing about the widthwise side of the notch as a fulcrum and to be able to be locked and fixed in a closed position, both ends of the connecting piece are bolted together. This has the advantage that the work of attaching and detaching the cover can be done more quickly and easily than in the case where the cover is attached and detached.

Below, an embodiment of the present invention will be described for an agricultural tractor. On the side of the engine E and the frame 2 that supports it,
A bonnet 4 with a rectangular cross section that covers the upper part of the engine part 1 such as the engine E and the radiator 3, side covers 5, 5 that cover the left and right sides of the engine part 1, and the front part of the engine part 1. A grill 6 is provided.

Among the side covers 5, 5, the side cover 5, which is connected to the exhaust manifold 7 of the engine E and has a substantially L-shaped muffler conduit 8 when viewed from the front, is inserted therein.The structure of the side cover 5 is as follows.

That is, a notch 10 is formed in the upper edge 5c of the side cover 5 to form an insertion hole 9 for the muffler conduit 8.

A connecting piece 11 is provided along the upper edge 5a of the side cover 50 to connect the opposite end sides 5a and sb at both ends of the notch 10.

The connecting piece 11 has one end pivotally attached via a pin 12 fixed to one end 5a of opposite ends of the notch 10, and the other end attached to the engagement groove. 13 and bolt 14
It is configured to be fixed via.

In the figure, 15 is a muffler, and 16 is an exhaust pipe, and the muffler conduit 8 and the muffler 15 and the muffler 15 and the exhaust pipe 16 are fixedly connected through pipe bands 17 and 17, respectively.
