DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cabin in a combine for cutting and threshing grain culm and the like.

[0002]

2. Description of the Related Art A cabin in a combine which can raise and lower a cabin surrounding a driving section is disclosed in Japanese Patent Laid-Open No. 63-2630.
It is already known from 19317.

[0003]

According to the known device, only the cabin moves up and down and the driver's seat remains unchanged.
When raising the cabin and looking at the weeding area, etc. diagonally forward and downward from a high place, it is necessary to stand up in an unnatural posture of a mid-lumbar state and operate while visually recognizing. And it was unstable when raised.

[0005]

An embodiment of the present invention will be described with reference to the drawings.
A self-removing threshing device 3 is mounted near one side of a machine base 2 having a traveling device 1, and an operation panel and a driver's seat 5 are sequentially provided on the other side from the front.
And a grain tank 6, and a pretreatment device 10 including a weeding body 7, a cutting blade, a grain culm raising device 8, a grain culm transport device, and the like are mounted on the front part of the threshing device 3 so as to be able to move up and down. At the rear of the grain tank, a collapsible grain discharging / discharging cylinder 11 is continuously provided, and the driver's seat 5 and the operation panel are integrally attached to the cabin 12, and operation from the operation panel is performed. If the system is not a cord or operation wire as an electric transmission means, but a manual operation amount transmission means such as a link that does not bend and stretch, the cabin 1
A plurality of transmission shafts are rotatably erected on the machine base 2 in the vicinity of the cab 2, and the bosses of the arms transmit rotation as link relay means, but are fitted so that they can move up and down. The boss is rotatable but not moved up and down by a metal protrusion protruded from the transmission shaft, and an arm attached to a lower portion of the transmission shaft is interlocked to a clutch arm or a transmission arm of a transmission.

[0006] The machine base 2 at the rear of the cabin 12
A pair of left and right guide rails 13, 13 each having a channel shape with an open inside are erected on the upper side thereof with a space therebetween in the left-right direction, and their upper ends are connected by a horizontal member.
Holes 12b for mounting the rear wall of the cabin 12
··· Drilling and bending the left side to the rear as viewed from the front, and the iron plate 1 on the rear surface of the portion along the inside of the right guide rail 13
2c, and a pair of triangular reinforcing plates 14, 14 are welded to the upper and lower sides on both sides of the mounting plate 12a at intervals, respectively, to form a pair of support shafts 15 displaced up and down.
a and 15b are fixed between the pair of reinforcing plates 14 and 14 by penetrating the bent portion or the iron plate 12c, and the other are loosely fitted in the elongated holes and are outside the support shafts 15a and 15b. Rollers 16... That roll in the grooves of the guide rails 13 and 13 are attached to the portion, a pipe 15c is loosely fitted inside one support shaft 15a, and inside the other support shaft 15b. Is a rocking arm 15d having an L-shaped cross section and fitting and fixing the pipes 15c.
And the support shaft 1 for the bent portion and the iron plate 12c.
A stopper 15e made of an L-shaped plate is welded to a portion corresponding to a portion between 5a and 15b, and a head of a bolt 18 is inserted into the hole of the swing arm 15d and tightened with nuts 17 so that the length can be adjusted. Is in contact with the plate surface of the stopper 15e. When the bolt 18 is rotated to increase its protruding length, the swing arm 15d is rotated, and the rolling surface of the pair of rollers 16 , 16 is rotated. Is the groove of guide rail 13
Moderately pressed against the front and rear inner surfaces, and
Two pairs of these rollers 16 arranged in a row
・ Before / after the inner surface of the groove of the guide rail 13
As a result , the cabin 12 is prevented from swinging back and forth and left and right .

An L-shaped support plate 19 is fixed to both lower sides of the mounting plate 12a, and a holder 20 having a U-shaped cross section is mounted inside the support plate 19 by bolts 20a, 20a so as to be adjustable in lateral movement. the lateral guide rollers 21, 21 rotatably supported as a vertical pair of the holder 20 from holes 22, 22 of the bent portion and the iron plate 12c is protruded outward into contact with the outer side surface of the guide rail 13, the Nuts 23, 23 are inserted into holes formed in the
It is configured so that the bolt 24, which can be adjusted forward and backward, can be positioned by contacting the holder 20.
This further prevents the lateral deflection of the cabin 12 in the left-right direction.
Is done .

Reference numeral 25 designates lower ends of the left and right guide rails 13 and 1.
A third hydraulic cylinder which is substantially pivoted on the machine frame 2 portion located in the middle of, the piston upper end, the mounting plate 12a
It is located approximately in the middle of supporting the left and right rollers 16.
It is connected to the bracket 26 protruding from the part with a pin,
When traveling on the road, the cabin 12 is
Is held at an intermediate height as shown by the solid line in FIG. 1, it is possible to steer in a stable state while looking forward,
When the vehicle is lowered as indicated by a chain line at the time of transportation, the vehicle can be transported by an ordinary vehicle without using a low floor vehicle.
In addition, it is raised as shown by the upper dashed line during the cutting and threshing operation. When the cabin 12 is moved up and down in this way, the driver's seat 5 and the operation panel are moved up and down integrally with the cabin 12, so even when the cabin 12 is set at an appropriate intermediate height, the cabin 12 is moved upward. Also at the time, the driver can perform the driving operation in the stable posture while sitting in the driver's seat 5, and can easily visually recognize the weeding state at the tip of the weeding body 7 by slightly leaning forward. .

When the hydraulic cylinder 25 is extended and retracted when the cabin 12 is raised and lowered, the hydraulic cylinder 25 is arranged in a line vertically on both left and right sides.
The left and right rollers 16 placed on the guide rail 13
Fit into the groove, especially while being guided on the inner surface before and after the groove
Rolling, and the side guide rollers 21, 21,.
While being guided by the outer surface of the guide rail 13 rolls, the cabin 12 is moved up and down in a stable posture without also tilts back and forth to the left and right. When the transmission and the engine E below or near the cabin 12 are maintained, the cabin 12 is raised and the left and right guide rails 1 are moved.
When the intermediate portions 3 and 13 are connected to the horizontal frame 31 by bolts or other appropriate means, maintenance work of the transmission and the engine E can be easily performed in a wide space.
