Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an engine cover attachment/detachment device for a combine harvester.

(Prior Art) In conventional combines, the engine is located between the rear of the seat and the paddy tank, and the engine cover is hinged so that it can be slid to the right and opened.

(Problem to be solved by the invention) The engine cover as described above is attached to the machine with a hinge, and when it is opened, the cover is still attached to the machine, so maintenance of the engine body is difficult. Also, maintenance of belts was not always easy.

Therefore, an object of the present invention is to provide an engine cover attachment/detachment device for a combine harvester, which allows easy repair and inspection of engines.

(Function) The engine cover of the present invention can be completely opened by sliding the engine cover toward the right side of the machine using the guide rail and sliding member.

(Example) The following description will be made based on the embodiments shown in the drawings.

FIG. 1 shows the entire combine harvester, in which a threshing section and a paddy tank section 2 are mounted on a crawler 1, and a pre-processing section is arranged at the front.

The pre-processing section consists of a lifting device 3, a reaping device 4, and a conveying device 5, which are installed on a reaping frame 6.

7 is a seat, and 8 is a steering column, which are installed on the step 9. 11 is a paddy receiving step below the paddy tank.

In the combine harvester described above, the engine is disposed between the rear of the seat 7 and the paddy tank 2, and is covered with an engine cover 10.

12 is the engine body, 13 is the air cleaner,
14 is a fuel tank, all of which are covered by cover 1.
Covered by 0.

It covers the upper, front, and right side of the engine so that it can be moved horizontally toward the right side with respect to the direction of travel of the machine, and the left side with respect to the direction of travel of the machine is covered. Not yet.

In order to make it slidable, guide rails 15 are arranged on the machine below the front and back of the cover, and the cover is pulled out by sliding the sliding members provided at the lower part of the front and back of the cover along the slide rails 15. It's becoming like that.

Further, there is a self-locking device 16 at the lower left side of the cover.

This locking device is of a type in which the locking device is activated simply by pushing the cover in, and is easily unlocked when a pulling force is applied.

This is shown in FIGS. 5 and 6.

That is, it utilizes an automobile door lock mechanism, and when the striker 17 installed on the engine cover 10 shown in FIG. The pin 18 advances and engages the slot 21 of the latch 20.

The latch 20 is always biased counterclockwise by a spring 22, and its slot 21 is aligned with the slot 19, so the pin 18 can enter, and the striker 17 advances while engaged in the slot 21. Then, the latch 20 rotates clockwise, and the lock pawl 23 engages with the corrugated surface a of the latch 20, so that the striker 17 is locked by the latch 20 and the cover 1 is locked.
0 cannot be off.

When the cover 10 is strongly pulled toward the right side, the lock pawl 23 and the corrugated surface a are disengaged, and the striker 17 can be removed from the latch 20.
The cover 10 can be removed by turning it toward the right side.

(Effect of the invention) The engine cover of the present invention is configured to be able to slide freely relative to the machine so that it can be moved rightward with respect to the direction of travel, so the engine cover can be moved horizontally to the right and the engine Since the cover can be removed from the machine and the engine can be completely opened, repair and inspection of the engine is easy. Moreover, since the sliding member of the cover slides on the guide rail on the machine side, deformation and damage to the lower end of the cover can be prevented, and there is no fear that the cover will become twisted and cannot be moved, and the drawer can be pulled out smoothly. Furthermore, when the engine is covered with a cover, a self-locking device works and the engine cover is locked to the machine, so the cover cannot be removed during work.
