Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain culm raising and transmitting device for a combine.

[0002]

2. Description of the Related Art This type of multi-row combine harvester has two types of transporting mowing culms, one in which the mowing culms are once collected on one side of the reaping device and then conveyed to the rear thresher. One of the two forms is known, in which a pair of left and right collecting devices formed in a V-shape when viewed in plan view collects harvested culms from both sides to merge them, and then conveys them to a rear thresher.

Even in the latter transport mode, in the conventional device, the transmission device of the central grain culvert raising device is transmitted from the rear transmission device similarly to the left and right grain culvert raising devices. The shaft was arranged diagonally forward and upward to transmit power.

[0004]

In the above-mentioned prior art, after the harvested grain culms are gathered from both sides and merged by a pair of left and right collecting devices formed in a V shape when viewed in plan, the threshing machine at the rear side. In the case where the grain culm is being conveyed, the transmission of the central grain culm raising device located in front of the merging portion of the collecting device and its related members obstruct the conveyance, and Had a turbulence in its vicinity.

[0005]

That is, according to the present invention, a plurality of grain culm raising devices 2, 2 ', 2 "are obliquely installed from the front position of the reaping device 1 in a rearward rising posture, and the grain culm raising devices are raised. Device 2,
A pair of collecting devices 3 for collecting and consolidating the cut culms from the left and right sides above the reaping device 1 below the rear of 2 ', 2 ".
3'is provided, and a grain culm conveying device 5 is provided between the rear ends of the collecting and feeding devices 3, 3'and the rear thresher 4, and the plurality of grain culm raising devices 2, 2 ', 2 are provided. Of the above-mentioned delivery device 3, 3 '
In order to configure the grain culm raising device 2 ′ arranged in front of the confluence part 6 to be transmitted by the transmission shaft 8 extending forward and upward from the transmission device 7, the transmission shaft 8 is predetermined from the confluence part 6. After extending to a position ahead by a distance, the grain culm raising device is characterized in that it is bent and erected toward the upper rear surface of the grain culvert raising device 2 ', and has a V shape when viewed from the side. It is configured as a transmission device.

[0006]

The combined grain culm erecting and transmitting device according to the present invention comprises a pair of right and left collecting and feeding devices 3,
In the merging portion 6 of 3'or in the vicinity thereof, it is possible to smoothly convey without receiving a conveyance obstacle. That is, after extending the transmission shaft 8 to the grain culm raising device 2 ′ arranged in front of the merging portion 6 to a position forward by a predetermined distance from the merging portion 6, to the upper rear surface of the grain culm raising device 2 ′. It is configured so as to be bent and erected toward the side so as to form a V shape in a side view.

Therefore, the grain culms collected by the collecting devices 3 and 3'pass through both sides of the transmission shaft 8 and join at the merging portion 6 located a predetermined distance behind the transmission shaft 8. The grain culm transporting device 5 further transports the grain culm rearward to supply the thresher 4. As a result, the transmission device such as the transmission shaft 8 to the central grain culm raising device 2 ′ and its related members do not hinder the transportation of the grain culm by the collecting devices 3 and 3 ′, and the merging portion 6 or It is possible to smoothly convey the grain culms in the vicinity without causing disorder.

EXAMPLE A combine 9 has a threshing machine 4 mounted on a chassis having a crawler 10 and a frame 12 having a plurality of grass bodies 11 at the front is rotatable up and down by a hydraulic device 13 in the front. Is configured. The reaping device 1 is attached to the middle lower part of the frame body 12 in a lateral direction so that a multi-row grain culm row can be cut.

The cutting device 1 employs a conventionally known reciprocating cutting blade. Grain culm raising device 2, 2 ', 2 "
The front end of the mowing device 1, the starting end portion of the grass body 1
It is located at the rear of 1 and is provided with the end portion inclined obliquely upward from the middle portion so that a multi-row grain culm row can be raised. The grain culm raising devices 2, 2 ′ and 2 ″ have a construction generally known in the prior art, and include a raising case 14 and a raising lug 15.

The collecting and delivering devices 3 and 3'include the collecting and delivering lug 1.
6 and a star wheel 17, from the upper front of the cutting device 1 to the rear thereof so as to have a V-shape in plan view,
The starting end portion is wide on both right and left sides, and the end portion is made to be a confluence portion 6 so that the transportation grain stems can approach each other.
The grain culm transporting device 5 is composed of a base transport chain 19, a root transporting device 20, and a tip transporting device 21 between the above-mentioned confluence portion 6 and the start end of the transporting device 18 of the threshing machine 4, and removes the harvested grain culm from the threshing machine 4. It is configured so that it can be transported and supplied to.

The transmission device 7 connected to the frame 12 side is configured to be transmitted via a transmission shaft 23 installed in the support cylinder 22. Next, the grain culm raising device 2,
First, 2'and 2 "of the left and right sides are configured so that the left and right outer ones 2 and 2" can be transmitted from the transmission device 7 via a transmission shaft 25 installed in a support pipe 24.

The central grain culm raising device 2'located in front of the confluent portion 6 has a pipe 26 extending downward from the transmission device 7 toward the front, and the grain culm raising case 1
4 is connected to the support cylinder 27 attached to the back side of the drive shaft 4, and is driven by the transmission shaft 8 communicating with the inside thereof. The transmission shaft 8 extends to a position forward by a predetermined distance from the confluence portion 6 and then is bent and erected toward the upper rear surface of the grain culm raising device 2 ′ to form a V shape in a side view. To do.

The operation will be described below. While driving the rotating parts of the machine, propel the machine with the crawler 10,
Start reaping threshing work. First, the grain culms in the field are weeded by the sward body 11 in the front part of the machine body, and from the base thereof, the grain culm is raised by the raising lugs 15 of the grain culvert raising devices 2, 2 ′, 2 ″, and is successively erected. It becomes a state.

In this way, the grain culms reach the mowing device 1 and are mowed, and the collecting lugs 16 of the pair of left and right collecting devices 3, 3'collect the multi-row culms in the central direction of the machine body. They are merged by the star wheel 17 and further transported to the rear. Then, the grain culm is passed from the base transport chain 19 to the root transport device 20 and the tip transport device 21, and is supplied to the threshing machine 4.

During the series of operations as described above, the grain culm is arranged such that the transmission shaft 8 for transmitting the central grain culm raising device 2'located in front of the merging portion 6 merges the collecting devices 3, 3 '. Since it is not in the vicinity of the portion 6, it is possible to smoothly carry it without suffering a transportation obstacle.
