Description

[Detailed description of the invention] This invention relates to a tractor cabin door.

In order to run smoothly in soft fields, when using tracks wrapped around the auxiliary wheels and rear wheels, the tracks get in the way of the bottom of the cabin door, making it difficult to open the cabin door when necessary to get on and off. That is difficult.

Therefore, in this invention, the sliding door can be held in a raised position where the opening/closing operation of the cabin door does not interfere with the tracks, or in a lowered position where the lower edge of the sliding door is located near the floor of the cabin. The structure has been devised so that getting on and off the vehicle can be done without any problems.

The specific structure will be explained based on one embodiment shown in the drawings. As shown in FIG. The cabin door 1 includes a sliding door 4 which is formed of a profile and has sliding door frames 3 at both front and rear ends that are fitted into the locking guide portion 2a and can slide up and down along the door frame 2.
The vertical position of the sliding door 4 relative to the cabin door 1 can be adjusted by pressing the threaded portion 5a at the tip of the lock knob 5, which is fitted into the lower part of the sliding door frame 3 and screwed into the sliding door frame 3, against the side surface of the door frame 2. to form.

When the sliding door 4 is pushed up to the highest position, it is removably supported by each of the rear wheels 6 of the tractor and in front of the rear wheels 6 and below near the access area to the cabin. An endless crawler track 8 wrapped around the auxiliary wheel 7
The sliding door 4 is held in a lifted position where the lower edge of the sliding door 4 located at the bottom of the cabin door 1 that is open to the outside does not interfere at all. The lower edge of the vehicle is held in a lowered position near the floor of the cabin.

Note that a handle 9 is provided on the inner surface of the sliding door 4.

Since the cabin door according to this invention is constructed as described above, when the sliding door 4 is held in the lowered position, the sliding door 4 is positioned near the floor of the cabin, thereby closing the side of the cabin. When the sliding door 4 is held in the raised position, the lower part of the sliding door 4 does not get in the way when the crawler belt 8 is wrapped around the auxiliary wheels 7 and the rear wheel 6, so the cabin door 1 can be opened as needed for getting on and off.
