Description

[Detailed Description of the Invention] The present invention is for opening and closing an engine cover.

More specifically, the present invention relates to an opening/closing device for an engine cover of an engine for agricultural machinery.

The engine cover is divided into a fixed cover and a rotary part, and the movable cover is rotatably supported on a vertical rotation fulcrum provided on the side edge of the fixed cover so that it can be opened and closed laterally. , the movable cover side may droop downward due to its own weight, creating a step between it and the fixed cover, and a gap may be formed between the two force bars.

Such a gap allows debris such as straw to enter the engine, resulting in a problem of fire.

For this reason, conventionally, a downwardly inclined guide plate is provided along the upper edge of the fixed cover and protrudes outward, and the lower end of the upper edge of the movable cover is guided and held on top of this guide plate. Efforts are being made to eliminate the vertical head difference between the two force bars.

However, if the downward inclination angle of this guide plate is too large, the movable cover can be opened and closed relatively smoothly, but there is a drawback that a step is likely to occur between the guide plate and the fixed cover.

On the other hand, if the downward inclination angle is too small, there will be no difference in level between the movable cover and the fixed cover, but the two force bars will interfere with the movement of the movable cover to close it, making opening and closing operations difficult. It has the disadvantage that it must be closed while being lifted.

The purpose of this invention is to eliminate the above-mentioned drawbacks of the conventional technology, and to make it possible to open and close the movable cover smoothly, but to avoid creating a step between the fixed cover and the movable cover when closed. The object of the present invention is to provide an engine cover device that is designed to improve the engine cover.

The engine cover opening/closing device of the present invention which achieves the above object is an engine cover in which the movable cover is configured to be able to be opened/closed in the horizontal direction about a vertical rotation fulcrum provided on the side edge of the fixed cover. A horizontal regulating surface that regulates the lower edge of the movable cover side is provided on the fixed cover side of the upper mating surface of the double force bar, and a guide surface on the fixed cover side that protrudes from the regulating surface toward the movable cover side. , it is characterized in that it is inclined in a direction that becomes steeper downward as it approaches the rotation fulcrum side with respect to the horizontal regulating surface.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to embodiments shown in the drawings.

In the figure, 1 is an engine, and a fixed cover 2 is fixed to one side so as to cover the engine 1. A movable cover 3 is pivotally supported on the side edge of this fixed cover 2 via a hinge 4, and It is designed to be able to be opened and closed freely.

Reference numeral 5 denotes a clasp, which fixes the double force bars 2 and 3 when the movable cover 3 is closed to the fixed cover 2.

Guide surfaces 6 and 7 are provided on the upper edge and both side edges of the fixed cover 2, respectively, so that the guide surfaces 6 and 7 protrude so as to be bent inward and then inclined outward.

Of these guide surfaces 6 and 7, the guide surface 6 provided along the upper edge of the fixed cover 2 has a large inclination angle with respect to the horizontal direction on the rotation fulcrum side of the movable cover 3 where the hinge 4 is provided. The angle of inclination gradually decreases as the distance from the rotation fulcrum side increases.

That is, as shown in FIG. 1, the fixed cover 2 side of the guide surface 6 forms a horizontal regulating surface so that the lower edge of the movable cover 3 can be constrained by the brush stroke indicated by the chain line A-A. From this regulating surface: the movable cover 3 is inclined as shown by the chain line B-B.

8 is an adduct installed in the engine 1.

In the engine cover described above, the movable cover 3 has a tendency to hang down from the fixed cover 2 by a distance below the fixed cover 2 due to its own weight, as shown in FIG.

:: When the movable cover 3 is opened, the movable cover 3 is in a state of hanging down with a drop of distance, but when the movable cover 3 is closed from this state, the upper edge of the movable cover 3 is bent. The tip of the fixed cover first comes into sliding contact with the side of the second guide surface 6 of the fixed cover near the hinge 4, and is gradually guided to slide up in a direction away from the hinge 4.

As described above, the guide surface 6 has a large inclination angle on the rotation fulcrum side of the It hinge 4, and is formed to gradually become smaller as it moves away from the pivot side, so that the movable cover 3 is closed as described above. When it comes into sliding contact with the guide surface 6, it gradually slides upward, and when it is completely closed, the difference in distance is corrected and there is no step between it and the fixed cover 2.

Moreover, since the movable cover 3 can be closed by sliding up the slope of the guide surface 6 as described above, it can be performed extremely smoothly.

As mentioned above, the engine cover opening/closing device of the present invention has the following features:
In the engine cover in which the movable cover is configured to be able to be opened and fixed in the horizontal direction around a vertical rotation fulcrum provided on the side edge of the fixed cover, the movable cover is disposed on the fixed cover side of the upper mating surface of the double force bar. A horizontal regulating surface is provided to regulate the lower edge of the side, and a guide surface of the fixed cover protruding from the regulating surface toward the movable cover is placed on the rotation fulcrum side with respect to the horizontal regulating surface. Because the movable cover is tilted in a direction that becomes steeper downward as it approaches, the movable cover can be opened and closed smoothly. Eliminates the step between the cover and the
It is possible to prevent dirt and the like from entering the engine cover.
