号で開示されている。[Prior Art] Conventionally, as a multi-row harvesting combine, a reaping section has a long reciprocating cutting blade that matches the width of the machine, and a conveyance device that conveys the grain culm cut by the cutting blade. For example, a device equipped with a threshing section having a feed chain, and in which the cutting blade and the conveying device are mounted on the same frame so that both can be rotated to the left and right at the same time with respect to the combine main body is disclosed in Utility Model No. 50-17435, for example.
Disclosed in the issue.
［発明が解決しようとする問題点］

れないという問題があつた。[Problems to be solved by the invention] Since the cutting blade rotates independently with respect to the machine body together with the conveying device, even if the combine main body is tilted from side to side, the cutting blade remains almost parallel to the field surface. On the other hand, since the conveying device also tilts to the left and right along with the cutting blades, the relative position between the end of the conveying device and the starting end of the feed chain shifts, causing the receiving of the grain culm. There was a problem with the joints not being done properly.

するものである。[Means for Solving the Problems] Accordingly, the present invention provides a method in which the substantially central portion of the cutting blade in the left and right longitudinal direction is pivotally supported to be tiltable left and right with respect to the frame of the cutting section so that it can tilt independently. , a sled or a sensor is provided at both left and right ends thereof, and the reaping section is mounted so as to be rotatable back and forth at a position near where the terminal end of the conveying device and the starting end of the feed chain of the threshing section face each other, and the reaping section is rotatably attached to the conveying device. By keeping the relative position of the feed chain almost constant, even if the combine main body (traveling body) is tilted, the cutting blades can tilt left and right independently and are always held almost parallel to the field surface, allowing the cutting blades to remain almost parallel to the field surface. By reaping at a constant height, it is convenient for the subsequent processing of the reaped grain, such as transportation of the reaped grain culm, transfer of the grain culm from the transport device to the feed chain of the threshing section, threshing work, and reaping marks. The aim is to provide a combine that brings about the same results.

A frame 6 of the reaping section 5, which is equipped with a crank finger 5c, a conveying device 5d for conveying the harvested grain culm toward the threshing section 2, etc., is pivoted so as to be rotatable in the front-rear direction. A hydraulic cylinder 7 is provided between the lower part and the transmission box 3.
The reaping section 5 is rotated about the pivot shaft 4 and raised and lowered by the expansion and contraction of the hydraulic cylinder 7, so that the vertical movement can be adjusted. During this vertical movement, since the pivot shaft 4 is provided near the starting end of the feed chain 2a of the threshing section 2, which faces the terminal end of the conveying device 5d, the conveying device 5d and the feed chain 2

２で脱穀される。 In a combine harvester having such a configuration, when performing harvesting work, the hydraulic cylinder 7 is contracted to lower the reaping section 5, and each section is driven with the sleds 11, 11 of the cutting blade 10 in contact with the reaping field. Car body 1
When the culm is run, grain culms in the field are divided by the weed cutting body 5a, pulled up by the grain culm lifting device 5b and guided into the reaping section 5, and the base of the grain is harvested by the cutting blade 10 and placed in the crankshaft. Scratched by swinger 5c,
The grains are held by the conveying device 5d and sent to the feed chain 2a of the threshing section 2, where they are taken over and threshed by the threshing section 2.

い。 During such harvesting work, even if the vehicle body 1 tilts to the left or right depending on the field condition, and the reaping unit 5 also tilts to the left or right, the cutting blade 10 independently moves left and right around the support shaft 9. Since the grain culm is harvested by tilting and keeping the sleds 11, 11 (or the ground sensor) in contact with the ground, the cutting blade 10 is always approximately parallel to the field surface, whether the vehicle body 1 is in the normal or inclined position. The grain culm can be harvested at a nearly constant cutting height. Therefore, the conveying posture of the grain culm, which is scraped by the crank finger 5c and supplied to the feed chain 2a of the threshing section 2 by the conveying device 5d, is almost constant and is conveyed in an orderly manner. In addition, the grain culm transported by the transport device 5d and supplied from its terminal end to the starting end of the feed chain 2a of the threshing section 2 is reliably transferred, and a good threshing operation is performed. Furthermore, when wheat is sown directly into a field after harvesting, for example, as a second crop, it is convenient if the height of the stubble is constant so that it does not interfere with the sowing operation using a seeder.

A support mechanism is provided to support the cutting blade, such as a sled or a sensor, at a predetermined height, and the relative position between the end of the conveying device and the start of the feed chain in the threshing section is approximately constant. It is possible to always reap objects such as grains at a constant cutting height without damaging the cutting blade, and the subsequent transportation of grain culms can be carried out smoothly. The splicing is reliably performed, resulting in good results in the threshing work, and furthermore, there is no loss of the harvested grain culms, etc., and the cutting height is uniform, which is convenient for subsequent work.
