Abstract

PROBLEM TO BE SOLVED: To enable to exchange a step for getting on and off to an acting posture and a housed posture by a simple operation. SOLUTION: A step for getting on and off 15 is installed under a cabin door 6 to be interlocked with opening and shutting of the cabin door 6. The step for getting on and off 15 take an acting posture that the step 15 overhangs toward the outside of the lateral side of a machine body when the cabin door 16 is open and a housed posture that the step is withdrawn into the machine body when the cabin door is closed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a combine.

[0002]

2. Description of the Related Art In a combine, a middle splitting work is performed in which a crop is cut between crops. Therefore, when a step for getting on and off is provided, the step is defined by an action posture projecting laterally outward of the aircraft and a retirement into the aircraft. The operating position is set only when the user gets on and off the vehicle, and the operating position is set so as not to hinder other operations. As an example, there is a combine disclosed in Japanese Utility Model Laid-Open No. 2-90158.In this conventional technique, a step for getting on and off is provided in the working posture and the storage posture so as to be swingably switchable around a longitudinal axis. It was configured such that the operator could directly perform the swing switching operation with the foot or hand.

[0003]

According to the above-mentioned conventional configuration, the operator directly swings the steps with his / her feet or hands, so that the switching operation is troublesome. Especially when getting out of the cabin, after opening the cabin door, check the location of the steps, swing down and open in an unstable posture while lowering one foot, which is troublesome. there were.

[0004] An object of the present invention is to enable the step for getting on and off to be switched between the operating position and the retracted position without performing any special operation, thereby saving the trouble of the switching operation that has been required so far and maneuvering. The point is to reduce the burden on people.

[0005]

[Means for Solving the Problems]

[Structure] The characteristic structure of the invention according to claim 1 is that a step for getting on and off is provided below the cabin door so as to interlock with opening and closing of the cabin door, and the step for getting on and off is performed when the cabin door is opened. It is configured such that the operating posture extends to the laterally outward side of the aircraft, and when closed, the operating posture retreats into the aircraft.

A feature of the invention according to claim 2 is that, in the invention according to claim 1, the step for getting on and off is connected to a lower end portion of the cabin door.

According to the first aspect of the present invention, when the cabin door is opened, the steps for getting on and off the vehicle are in the operating posture projecting laterally outward, and when the cabin door is closed, the cabin is in the retracted posture in which the cabin door is retracted. This eliminates the need to switch between steps for getting on and off.

According to the second aspect of the present invention, the same operation as that of the first aspect can be obtained, and the step for getting on and off is connected to the lower end of the cabin door. In addition, the step for getting on and off can be smoothly and reliably linked to the opening and closing of the cabin door, and, for example, a structure is provided in comparison with a structure in which a switching lever is provided in the cockpit and the switching lever and the step for getting on and off are linked. Simple and easy to maintain.

According to the first aspect of the present invention, the step for getting on and off can be switched between the operating position and the retracted position without performing any special operation only by performing the door opening / closing operation required for getting on / off. As a result, the switching operation can be omitted and the burden on the operator can be reduced.

According to the structure of claim 2, in addition to the effect similar to the effect of the structure of claim 1, the handleability can be improved, the structure can be made compact, and the maintainability can be improved. Can be improved.

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a pre-cutting device B including a pulling device 4 and a cutting device 5 at the front of a traveling machine A including a control cabin 1, a threshing device 2, a Glen tank 3, and the like. Are attached to form a combine.

As shown in FIGS. 2 and 3, a step 15 for getting on and off is provided below the cabin door so as to interlock with opening and closing of the cabin door 6. When the cabin door 6 is opened, the step 15 for getting on and off is obtained. Has a working posture that protrudes outward from the lateral side of the machine body (FIG. 4B), and when closed, it is configured to be in a retracted posture (FIG. 4A) that is retired into the machine body. In other words, a pentagonal tread plate 16 is provided in a cantilever manner at the front half of the lower end of the cabin door 6, and a guide plate 18 for guiding the tread plate 16 from above is provided on the body frame 17 side. The guide plate 18 is provided with a pin 19 and an arcuate guide hole 18a for guiding the guide pin 19 as the cabin door 6 opens and closes. Further, a nut 7 is screwed into a female screw portion formed at the upper end of the guide pin 19, and the guide plate 18 is sandwiched between the nut 7 and a head 19a formed at the lower end of the guide pin. , The downward load applied to the guide plate 18
It is configured to be supported by the guide plate 18.

[Another Embodiment] The portion corresponding to the step board may be formed by a rod-shaped member.

Although not shown, the step 1 for getting on and off the vehicle
5 is provided with biasing means for extending and biasing the outer side of the fuselage.
The storage position may be set by retracting into the body against the urging force, and holding means for holding the storage position may be provided.
