Description

[Detailed description of the invention] In order to easily connect and release the engine bonnet part from the fixed member, the present invention has a locking member attached to one of the engine bonnet part and the fixed member, which can be opened and closed, and the other to the fixing member. The present invention relates to an engine bonnet fixing structure for a working vehicle, in which a locking member is provided with a removable tension catcher.

In the above structure, since the catcher has a weak binding force in the direction crossing the pulling direction, the engine bonnet part tends to move in the direction crossing the pulling direction, which causes backlash. There was an easy problem.

In view of these circumstances, the present invention aims to solve the above-mentioned problems by adding a simple structure without impairing the operability of the catcher.

Embodiments of the present invention will be described in detail below with reference to illustrative drawings.

A traveling body 2 equipped with a crawler type traveling device 1 is provided with a rotating base 3.
The boom 5 is configured to be rotatable around the vertical axis, and the driving unit and the control unit are mounted on the swivel base 3, and the boom 5 is mounted on a bracket 4 provided on the swivel base 3 so as to be rotatable around the vertical axis. ,
Arm 6 and packet I are sequentially pivotally connected together with
A boom cylinder 8 is installed between the bracket 4 and the boom 5,
An arm cylinder 9 is installed between the boom 5 and the arm 6, and a packet cylinder 1 is installed between the arm 6 and the packet 7.
0 are respectively disposed to constitute an excavator who performs excavation work toward the vehicle body.

The engine bonnet part 11 that covers the driving parts of the engine E and the like mounted on the swivel base 3 is configured to be able to swing freely about one front and rear axis using a hinge fitting, and the swing axis P1 and A hook 1 as an example of a locking member is attached to the engine bonnet portion 11 on the opposite open side.
A fitting member 13 is welded to the swivel base 3, and a swinging member 15 is pivotally connected to the bonnet member 14 fixed to the swivel base 3 so as to be swingable about the horizontal axis P1. Furthermore, a lever 1 is attached to this swinging member 15 around the horizontal axis P3.
6 is pivotally connected to the lever 16, and the cylinder 17 is pivotally connected to the lever 16 around the horizontal axis P3, and the catcher 18 loosely inserted into the cylinder 17 is biased toward the contraction side by the spring 19. and closed bonnet part 110 hook 12
With the catcher 18 engaged, the lever 16 is forcibly swung downward to pull and connect the engine bonnet portion 11 to the fixed bonnet member 14.

The swinging member 15 and the fitting member 13 are each formed to have a U-shaped cross section, and as the swinging member 14 swings, the fitting member 1
The catcher 18 is configured to suppress movement of the engine bonnet portion 11 in a direction crossing the pulling direction, thereby suppressing rattling.

Note that the locking member 12 may be provided on the fixed member 14, and the catcher 18 may be provided on the engine bonnet portion 11.In addition, the shapes of the swinging and fitting members 15 and 13 can be changed. It is sufficient that the swinging member 15 can be fitted into and separated from the fitting member 13 by swinging around the uniaxial center P2.

In summary, in the present invention, the swinging member 15 to which the catcher 18 is attached in the engine horn net fixing structure described at the beginning is mounted to the engaging member 12 side as it swings around its -axis P2. In the fitted state, the swinging and fitting members 15 and 13 are relatively movable in the pulling direction of the catcher 18 and intersecting with the pulling direction. It is characterized by being constructed so that relative movement in the direction of movement is impossible.

In other words, since the catcher 18 provides the members 13 and 15 that fit together in the direction crossing the drawing direction, the movement of the engine bonnet portion can be strongly suppressed by fitting these two members 13 and 15. The noise caused by the engine bonnet can be suppressed, and the catcher 1
8 is attached to the swinging member 15, and a member 13 that fits into this member 15 is provided. In addition, both members 13 can be swung to operate the catcher 18. .15 can be engaged and disengaged, so the operability of the catcher 18 is not impaired, and the engagement and disengagement operations can be easily performed.
