Description

[Detailed description of the invention] Conventionally, in a combine harvester in which a preprocessing section is attached to the front part of the machine so that it can swing up and down, the drive device of the preprocessing device is placed between the control section and the grain culm conveying device of the preprocessing section. Because of this, maintenance work on the drive unit, such as belt replacement, had to be carried out under the fuselage, which was extremely dangerous and difficult, and also had the drawback of increasing the width of the machine.

The purpose of the present invention is to improve the above-mentioned drawbacks, and the purpose of the present invention is to mount a threshing device on one side of the machine base, and provide a control section protruding forward from the threshing device on the other side. In a combine harvester in which a preprocessing section extending from the front part of the device, the side part of the control section, and the front of the control section is attached to the front part of the machine so as to be swingable up and down, the horizontal frame at the front end of the control section is attached. The horizontal frames are provided at intervals on the left and right, and the horizontal frames are connected by an arch-shaped underframe. It is characterized by a transmission belt that runs under the belt.

The embodiment shown in the drawings will be explained below.1
is a threshing device mounted on one side of a machine base 3 having a traveling device 2, and on the other side, an operating panel 17, a driver's seat 5, a paddy bagging section 4, etc. are arranged in order from the front, At the front, a pre-processing section 7 consisting of a reaping section 6 and a conveying device for conveying and supplying the harvested grain culms to the threshing device 1 is mounted so as to be able to swing up and down.

A control frame 8 is located on the control section side of the aircraft platform 3.
is erected as a frame, and the horizontal frame 8a at the top of its front end is divided into left and right parts at intervals, and their inner ends are welded to the frames 8b, 8b in the front and rear directions, and when viewed from the front, the horizontal frame 8a is As shown in FIG. 3, they are integrally connected by an underframe 9 which has an arch shape and whose top surface slopes upwardly toward the front when viewed from the side.

Reference numeral 10 denotes a box-shaped side clutch lever bracket whose lower part is screwed onto a bracket 11 welded to the upper surface of the underframe 9 with bolts 12.
Side clutch levers 13, 13 are attached to the upper part.

Reference numeral 14 denotes a lever frame fixed with bolts 15 on the horizontal frame 8a on the right side when viewed from the front,
A wide U-shaped driving panel stand 16 opening rearward in plan view is welded to the front surface of the side clutch lever bracket 10, and the lower left side in front view is connected to the bracket 8 on the horizontal frame 8a.
The lever frame 1 is screwed onto the lever frame 1 on the right side.
4 with bolts 14a, 14a.

Note that the lower part of the operation panel stand is cut out to match the underframe 9.

Reference numeral 17 denotes an operating panel which is lowered on the side of the threshing device 1, and is removably screwed to the operating panel stand 16 by bolts 18 and to the lever frame 14 by bolts 18', 18'. The side clutches 13, 13 are inserted near the center of the high part, and a pair of left and right driving stays 19, 19 are removably inserted into the outer sides of the side clutches 13, 13.
Since the lower ends of the operation stays 19, 19 are attached to seats projecting from the inner surface of the upper part of the operation panel stand 16, the operation panel 17 can be pulled out upward by removing the bolts 18, 18'. can.

20 is a lever panel provided on the side of the thresher 1 of the driver's seat 5, and its front end is connected to the operation panel 17.
The plate is joined to the lower part of the seat and slopes downward until just in front of the driver's seat 5, and from there the rear part extends rearward substantially horizontally at a sufficiently lower height than the seating area of the driver's seat 5, with the plate surface facing the driver's seat 5. Various levers 21, 22, 23, 24, 25 are provided on the inclined portion 20a and the lower portion 20b, and levers 23, 2 provided on the lower portion 20b.
The grips 4 and 25 are slightly higher than the seating area of the driver's seat 5, allowing the driver to easily operate these levers while seated. The levers 21 and 22 in that area are facing the driver's seat 5, making them easy to see.
It is further away from the front, but higher, so the driver can easily operate it in a natural posture without having to lean forward too much.

Reference numeral 26 is a safety cover provided extending from the front outside of the lever panel 20 to the slightly rear part of the supply port of the thresher 1, and the front part of the safety cover is attached to the lever frame 14 by bolts 14a, 14a to the operating panel. It is screwed together with the stand 16, and a recess 27 extruded toward the pre-processing section 7 is provided in the intermediate portion, into which a reaping speed change lever 28 is inserted.

Reference numeral 29 is a floor provided on the control frame 8, and the front part thereof is connected to the control panel stand 1 from both sides of the underframe 9.
6, so the driver can drive in a natural manner with his or her feet freely extending over this extension.

A drive pulley 31 driven by the engine is pivotally supported on a bracket 30 vertically disposed on the control section frame 8, and the drive pulley 31 and the input pulley 32 of the preprocessing section 7 are hung from each other. Since the belt 33 is located directly below the underframe 9, when the preprocessing section 7 is raised from the working position shown by the chain line in FIG. 4 to the position shown by the solid line when the machine is rotating or traveling on the road, the belt 33 is It enters into the underframe 9 together with the belt cover 34, and the pretreatment section 7 can be raised to a desired height.

Furthermore, when replacing the belt 33, the belt 33 can be replaced from the side without having to go under the machine body with the preprocessing section 7 lowered.

In the drawing, 35 is a pretreatment frame, 36 is a pretreatment cover, 37 is an engine room, and 38 is a tension clutch.

As mentioned above, the present invention has a threshing device mounted on one side of the machine base, and a control section that protrudes forward from the threshing device on the other side, and connects the front part of the threshing device and the side part of the control section. In a combine harvester in which a pre-processing section extending from the front of the control section is attached to the front part of the machine so as to be able to swing up and down, horizontal frames at the front end of the control section are spaced from side to side, and these horizontal frames are The transmission wheel is connected by an arch-shaped underframe and is pivotally supported at the bottom of the floor of the control section, and the transmission wheel is pivotally supported at the pre-processing section.
Since the power transmission band that passes under the underframe is hung, there is no need to provide a space between the control section, the threshing device, and the preprocessing section to hang the transmission band for driving the preprocessing section. In addition, the transmission belt can be hung within the width of the control section and the width of the machine can be narrowed, and the transmission band can be easily replaced from the control section side where the pretreatment section does not become an obstacle.
