The rolling shaft 32 for rolling the combine harvester is located at approximately the same height as the upper edge of the traveling device 2, and the horizontal sensor 53 for detecting the tilt of the machine is connected to the rolling shaft 32.
The root conveying device 5 is below the axis passing through and on the front side.
A reaping section rolling device in a combine harvester that is positioned below zero is described.

(Problems to be Solved by the Invention) The above-mentioned known device includes a rolling shaft 32 for rolling the reaping section.
Since it is located at approximately the same height as the upper edge of the traveling device 2 of the combine, there is a problem that mud from the traveling device 2 adheres to the rolling shaft 32.

In addition, a horizontal sensor 53 for detecting the inclination of the aircraft
is located below the axis passing through the rolling shaft 32, so there is a problem in that the horizontal sensor 53 is covered with splashed mud from the field.

In addition, since the horizontal sensor 53 is located at a lower position than the front root conveying device 50, there is a problem that it is covered with straw (numerals in this section and the previous section refer to the numerals in the prior art).

(Means for solving the problem) Therefore, in the present application, the reaping section 4 of a combine is rolled by a rolling device, and the rolling shaft 27 for rolling the reaping section 4 is higher than the traveling device 1 of the combine. The horizontal sensor 51 for detecting the inclination of the machine body is positioned near the axis 56 passing through the rolling shaft 27 and above the front root conveying device 10. It is something.

(effect) Next, we will discuss the effect.

(Overall operation) When the traveling device 1 rotates and moves forward, the power of the engine is transmitted from the transmission case 16 to the rotating shaft 13, which rotates the rotating shaft in the support tube 14 and bends the rotating shaft. The lifting device 6, the scraping star wheel 8, the front tip conveyor 9, and the front root conveyor 10 are rotated through the flexible portion 15, and the rear tip conveyor 11 and the rear root are rotated through the rotation shaft 13. The conveyance device 12 is rotated, and the clipper-type cutting blade 7 is reciprocated left and right to move forward.

Then, the weeds are divided by the weed splitter 5, the drooping tips are pulled up by the pulling device 6, they are harvested by the clipper-type cutting blade 7, they are raked by the raking star wheel 8, and the front tips are conveyed by the front tip conveyor 9 and the front roots are conveyed. device 10
The grains are collected and transported to the grain culm supply device 3 of the automatic feed type threshing device 2 by the rear ear tip conveyance device 11 and the rear side root conveyance device 12 for threshing.

(Action of the present invention) When the aircraft body tilts, the horizontal sensor 51
detects the inclination of the machine body, operates the raising solenoid or the lowering solenoid to expand and contract the cylinder 32, rolls the reaping section 4, keeps the reaping section 4 horizontal, and continues the work. During this work, the horizontal sensor 51 is located on the rolling shaft 2 when viewed from the side.
It is installed near the axis 56 of No. 7, and because of its high position, it is difficult for it to be covered with splashed mud from the field. Also,
When viewed from the side, the horizontal sensor 51 is located above the front tip conveying device 9 and the front root conveying device 10, so that less straw debris falls on it and it operates smoothly. In addition, since the rolling shaft 27 is located higher than the traveling device 1, mud splashed by the traveling wheels 1 does not hang on the rolling shaft 27.

(Effects) In the above-mentioned known method, since the rolling shaft for rolling the reaping section is positioned at approximately the same height as the upper edge of the traveling device of the combine, there is a problem that mud from the traveling device adheres to the rolling shaft. Further, since the horizontal sensor for detecting the inclination of the machine body is located below the axis passing through the rolling shaft, there is a problem in that splashed mud from the field hangs on the horizontal sensor. Further, since the horizontal sensor is located below the front root conveying device, there is a problem in that it is covered with straw debris.

However, in the present application, the reaping section 4 of the combine is rolled by a rolling device, and the rolling shaft 27 for rolling the reaping section 4 is a longitudinal axis located at a higher position than the traveling device 1 of the combine, and the machine body inclination is detected. The horizontal sensor 51 for use is a reaping section rolling device in a combine that is positioned near the axis 56 passing through the rolling shaft 27 and above the front root conveying device 10, so the reaping section 4 is rolled. Since the rolling shaft 27 is located at a higher position than the traveling device 1 of the combine, there is no risk that mud splashed by the traveling device 1 will adhere to the rolling shaft 27.
In addition, since the horizontal sensor 51 for detecting the inclination of the machine body is located at a high position near the axis 56 passing through the rolling shaft 27, there is no fear that the horizontal sensor 51 will be hit by splashed mud from the field. 51 is positioned above the front root conveying device 10, so there is no worry of straw debris getting caught.
