Abstract

PURPOSE:To provide the subject device capable of preventing the buckwheat from being pulled out when the buckwheat is reaped, by installing grass-dividing bars in the state projected forward from the sides of a reaping device. CONSTITUTION:Grass-dividing bars 6 are installed in the state projected forward from the sides of a reaping device 2 to divide the grass. The ends of grain straw guides 8 are pivotally installed near the ends of the grass-dividing bars 6 so as to enable to change the attaching angle of the grain straw guides 8 from a backward tilted state into a forward tilted state. When buckwheat is reaped. the grain straw guides are tilted forward to guide the buckwheat of the field into a reaper in the state pressing the buckwheat on the surface side of the field, thereby preventing a narrow guide 11 from being entangled with the buckwheat.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reversing guide device for a combine harvester, and is used in a general-purpose combine harvester, particularly when changing and adjusting it when harvesting rice or buckwheat.

0002

[Prior Art] The grain culm guide device (narrow guide device) in the pre-processing section of a conventional general-purpose combine harvester of this type extends rearward using the front end as a fulcrum, and there is no structure in which the inclination angle can be adjusted in this state. However, it was not configured to allow the tilt angle to be changed to a forward inverted state.

Therefore, with this configuration, there is no particular problem when harvesting rice or wheat, but when harvesting buckwheat, if you guide it in the same way as rice and wheat, some items will be pulled out, making continuous work difficult. It was extremely difficult.

0004

SUMMARY OF THE INVENTION The present invention aims to solve the problems encountered during sowing in so-called general-purpose combine harvesters that reap and thresh various crops such as rice, wheat, and buckwheat. That is, due to their nature, buckwheat noodles tend to get tangled with the narrow guide, and as the aircraft moves forward, they are often pulled out.

[0005] Therefore, an attempt has been made to prevent the buckwheat from being pulled out by guiding the buckwheat so as to press it against the lower field immediately before reaping, thereby allowing continuous reaping work.

[0006]

[Means for Solving the Problems] The present invention aims to improve the versatility of the above-mentioned general-purpose combine harvester, and to realize an apparatus capable of reaping buckwheat and the like in a continuous operation. That is, in a combine pretreatment device 5 having a raking reel 1, a reaping device 2, a raking auger 3, and a conveyor 4, the weeding rod is protruded forward from the side of the reaping device 2. 6, and a grain culm guide 8 is attached to the cutting rod 6 or the machine frame 7 near it, which can change the inclination angle between a backward inclined state and a forward inclined state with the front part as a fulcrum. be.

[0007]

[Embodiment] First, the configuration will be explained. The pretreatment device 5 includes a raking reel 1, a reaping device 2, and a raking ocher.
It consists of a gar 3 and a conveyor 4, and is attached to the front part of a vehicle platform 9 so as to be able to move up and down freely. To be more specific, the raking reel 1 is rotatably supported by a bearing on a support arm 10, and is configured to be able to rak in grain culms. The reaping device 2 adopts a reciprocating type and is configured to be able to mow over a wide range. The scraping auger 3 is configured to collect the harvested grain culms in the widthwise central portion of the pretreatment device 5 and to scrape and supply the harvested grain culms to the rear conveyor 4.

[0008] The conveyor 4 has a terminal end communicating with a grain supply port of the threshing room. The branching rod 6 is
They are located on both sides of the reaping device 2 and extend forward, making it possible to weed the grain culms in the field. 11 indicates a narrow guide.

In FIG. 1, the grain culm guide 8 has its end rotatably attached to the tip of the dividing rod 6, and the direction of inclination is shown in the solid line and the imaginary line in the drawing. It has a configuration that can be changed. In addition, the grain culm guide 8 is
A fixing device is provided at the rotation fulcrum part so that it can be fixed.

[0010]The embodiment shown in FIGS. 3 and 4 has a narrow
The guide 11 is configured so that its inclination direction can be changed back and forth with respect to the forward direction of the chassis between a normal state for reaping rice and wheat (FIG. 3) and a special state for reaping buckwheat (FIG. 4). That is, the narrow guide 11 is configured such that its end portion can be freely pivoted to the machine frame 7 and fixed at a predetermined position.

[0011] Next, its operation will be explained. first,
When performing normal rice harvesting work, the grain culm guide device 8 is tilted rearward as shown by the solid line in FIG. In addition, in the configuration of another embodiment shown in FIG. 3, it is fixed at the rear as shown in the drawing. Then, the machine moves forward while driving each rotating part of the machine to begin the reaping operation.

Then, the grain stems in the field are first raked backwards by the raking reel 1 rotating above, while the base part is being plucked by the raking rod 6. Then, the grain culm is harvested by the reaping device 2 and passed through the raking auger.
3 and is supplied to the conveyor 4. In this way, the grain culms in the field are fed to the threshing machine and threshed.

Next, the case of harvesting buckwheat will be explained. First, in FIG. 1, the grain stem guide 8 is tilted forward and fixed using the pivot point with the weeding rod 6 as a fulcrum as shown by the imaginary line. In addition, in the configuration of another embodiment,
As shown in FIG. 4, the narrow guide 11 is fixed so as to protrude forward in the direction of travel.

[0014] Then, when the reaping work starts, the buckwheat is
The grain is pressed against the ground side by the grain culm guide 8 and guided to the reaping device 2 as it is. Therefore, buckwheat is harvested by the reaping device 2 without becoming entangled with the grain culm guide 8 and being pulled out. In this way, when harvesting buckwheat,
Since the buckwheat is pressed against the ground by the grain culm guide projected forward, it can be reliably harvested without being pulled out.

[0015]

Effects of the Invention As described above, the reversing guide device for a combine harvester according to the present invention is particularly effective for harvesting buckwheat, and as the chassis moves forward, the buckwheat field can be pushed down to the ground side and mown as it is. Because it is a pull-out type, there is no pulling out that occurs with conventional narrow guides.
This allows continuous reaping work to be carried out reliably.

Moreover, the present invention can achieve the above-mentioned effects with a relatively simple configuration.
