Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine control floor and is provided with auxiliary steps that can be accommodated within the width of a machine.

[0002]

2. Description of the Related Art If a mowing operation is performed with an auxiliary step for mounting on a control floor protruding outward from the width of the machine body, it tends to be an obstacle to grain stems and the like. The storage is configured so that it can be pulled out and used only when necessary, but by storing this auxiliary step, it is often inconvenient when getting off the vehicle if the position of the control floor becomes high.

[0003]

According to the present invention, a step opening 4 having a fixed step 3 inside is provided on a floor side wall plate 2 in the vertical direction in an outer lower portion of a control floor 1, and a step opening 4 is provided inside and outside the step opening 4. In addition, an auxiliary step 5 for accommodating the fixed step 3 at a usable position is provided to form a combine control floor.

[0004]

When the auxiliary step 5 is brought out from the step opening 4 to the outside, the operator steps on the auxiliary step 5 and the fixed step 3 in the step opening 4 to operate the control floor 1
You can get on and off. When the auxiliary step 5 is unnecessary, the auxiliary step 5 can be stored in the step opening 4, so that it does not become an obstacle when a grain culm or the like approaches the outer surface of the floor side wall plate 2. Moreover, even when storing the auxiliary step 5,
Since the fixed step 3 is in a state where it can be used in the step opening 4 without being disturbed, when the auxiliary step 5 cannot be pulled out, the fixed step 3 alone can be used to get on and off.

In this way, the auxiliary step 5 which can be switched between the use state and the storage state has a simple structure in order to allow the step opening 4 having the fixed step 3 inside to come in and out, and the auxiliary step 5 of the floor side wall plate 2. It is possible to reduce the number of hooks such as grain culms on the outer surface, and this auxiliary step 5
Since the fixed step 4 can be used even when storing the
It is possible to easily get on and off under the condition that the auxiliary step 5 cannot be used.

EXAMPLE A combine is a threshing device 9, which supports a harvesting device 8 on a chassis 7 having a traveling device 6 in the form of a crawler so that the harvesting device 8 can be moved up and down, and receives grain culms harvested and conveyed from the harvesting device 8 to thresh. A grain tank 10 for accommodating grains to be threshed by the threshing device 9, a cutter 11 for cutting off culms after threshing, an engine in an engine cover 12, and the like are mounted, and the engine is driven to drive the vehicle while traveling. This is for cutting and threshing.

A control platform 13, a control floor 1, and a control seat 14 on an engine cover 12 are provided on one side of the front of the chassis 7. The control floor 1 is constructed on the upper side surface of a floor frame 15 framed on the chassis 7, and has a lift floor 16 at the center in the left-right direction, and fixed floors 17, 18 on both left and right sides thereof. Have. The elevating floor 16 is adjusted up and down integrally with or in conjunction with the cockpit 14, or independently, and is set to an elevated position when the driver operates in a posture of leaning forward.

On the outside of the floor frame 15, a floor side wall plate 2 in the vertical direction is formed integrally with the fixed floor 17 plate, and a step opening 4 is opened in the upper and lower intermediate portion. Inside the floor frame 15, there are a fixed step 3 and an auxiliary step 5 for the storage posture.
And the like, and forms a space 20 that can accommodate the operation valve 19 and the like of the hydraulic circuit.

The fixing step 3 is performed by the fixing floor 17
The operator's foot stepping on the step opening 4 is received along the lower edge of the step opening 4 at a right angle into the space 20. In this fixing step 3, a support bracket 21 having a U-shaped cross section in a plan view is integrally formed on the lower surface, and the support bracket 21 is integrally attached to the inside of the floor side wall plate 2 or the upper surface of the chassis 7.

The auxiliary step 5 is horizontally projected from the lower end of a step arm 22 having a "shape" when viewed from the front, and has an arm 23 directed downward from the upper end of the step arm 22. The lower end of the bracket is fixed to the inner side surface of the floor side wall plate 2 with respect to the bracket 24, and
The auxiliary step 5 is vertically rotatable about the shaft 25, is positioned below the fixed step 3 on the outside of the floor side wall plate 2 in the downward rotation position, and is in the upward rotation position. The switching operation can be performed so as to be positioned above the fixed step 3 inside the step opening 4 together with the step arm 22 and the like.

Such switching of the auxiliary step 5 is
The motor M is driven by electric power, and the motor M is mounted in the support bracket 21 with a motor stay 26, bolts 27, etc., and the shaft of the motor M is rotated via a gear 28. . The operation switch of the motor M is provided on the control stand 13. Reference numeral 29 denotes a stopper provided on the step arm 22, which can come into contact with the floor side wall plate 2 at a position rotated outward.

Reference numeral 30 denotes a valve stay, which is installed in the lower part of the space 20 in the left-right direction, and is provided on the upper surface of the operating valve 1 of various hydraulic circuits for the traveling operation and the reaping operation.
Install 9. One end of the valve stay 30 has a bracket 32 and bolts 3 with respect to the support bracket 21.
1, and the other end is attached to a floor frame 15 inside the machine to reinforce the floor side wall plate 2 having the fixing step 3, the auxiliary step 5, and the like. Reference numeral 33 denotes a rope hook fixed to the chassis 7.

When getting on and off the control floor 1 with the auxiliary step 5 stored, it is possible to step on the fixed step 3, and when getting out the auxiliary step 5 to get on and off, this auxiliary step 5 Also, it can be performed by stepping on the fixing step 3 and the like. Store auxiliary steps when harvesting combine or running on the road. Reference numeral 34 denotes a control lever, which can be rotated in the left-right direction and the front-back direction on the control base 13, and by rotating in the left-right direction, a part of the operation valve 19 is controlled, and a steering clutch and a steering brake are provided. It is possible to control the steering control operation by operating the etc., and to control the part of the operation valve 19 by rotating in the above-mentioned direction to control the cutting device 8 up and down. Three
Reference numeral 5 denotes a control stand cover, which is detachable so as to cover the front surface of the control stand 13. Reference numeral 36 is a floor cover that is attached to and detached from the front surface of the floor frame 15.
