Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a weed splitting device in a rush harvester.

[Prior Art and Problems to be Solved by the Invention] This invention provides a spiral weeding device for each of the two stalk culm passages formed in front of the reaping device. I uncut the tip of the spiral weed divider to be attached to υU 1
By arranging the spiral weed splitting device to be located forward from the tip of the weed splitting device on the side, and by configuring the spiral weed splitting device at a gentler angle than that of the weed splitting device on the uncut culm side, a single row of rushes on the cut culm side can be removed. The weeds are weeded quickly, and then the first row on the uncut culm side is weeded.

Therefore, it is possible to extend the life of the machine without applying a large weeding load at once, and the weeding position for the rush due to the spiral is vertically separated, especially during the first weeding action, as shown in Figure 1. It is extremely rare to have a victim because the grass is divided according to location.

Among the conventional rush harvesters of this type, there was no one that used a spiral type weed splitting device.

[Means to solve the problem]

This invention takes the following technical means to achieve the above object.

That is, the front of the reaping device 2, which is installed at a low front position of the traveling chassis 1, is divided by a support rod 3 that extends for one minute.
, 4', respectively #! on the side of the stem culm passage 4°4'. When the rotating weed splitting devices 5, 5' are provided, the starting end of the weed splitting device 5 on the cut culm side is located at the front and is configured to have a gentler inclination angle than the weed splitting device 5' on the uncut culm side. This is a weeding device for a rush harvester.

〔Example〕

The reaping device 2 is attached to a weed support rod 3 that projects forward from a traveling chassis 1 having a tall roller 6.

Reference numeral 7 denotes a stock transport device, which is composed of a pair of belts 8° 8', with a starting end located near the reaping device 2 and a terminal end located above the rear of the traveling vehicle 1.

9 shows a laddering device, and 10 shows a stalk culm tip conveying device.

The stem culm passages 4, 4' are divided by the weeding support rods 3 and 1
It is configured as a passageway for guiding the stem culm in rows to the reaping device 2.

The stem culm pulling devices 11 and 11' are located in front of the reaping device 2 and are inclined along the respective stem culm passages 4 and 4' with the starting end located downward and forward and the terminal end located at the rear upper part. There is.

The spiral weeding device 5, 5' has a spiral weeding device 12 mounted on the weeding support rod 3 of the stem culm passage 4 on the cut culm side, and on the other hand, the uncut side? A spiral branch 12 is provided in the side stem culm passage 4'.

The spiral weed dividers 5, 5' are arranged such that the helical weed divider 5 on the cut culm side is located forward of the helical weed divider 5' on the uncut culm side, and at a gentle inclination angle. .

In addition, if the spiral shape of the spiral type weeding device 5, 5' is configured so that the sloped surface is shaped like an abacus bead as shown in FIGS. 4 and 5, the stem culm of the rush will be damaged. There aren't many things.

Furthermore, as shown in FIGS. 6 and 7, the belts 8 and 8' constituting the stock conveying device 717 are arranged such that one belt 8 is shifted upwardly from the other belt 8', and the grass is spread under the belt 8'. If the elastic guide rod 13 attached to the support rod 3 is configured to press against the support rod 3, two rows of rush can be accurately pinched and guided.

That is, stem f? The stem culm of the passage 4' is held between the elastic guide rod 13 and the belt 8', and when it reaches the other belt 8, it is transferred from the elastic guide rod 13 to that belt 8.

Further, the stem culms on the side of the stem culm passage 4 are harvested and at the same time are held by the belts 8, 8' and conveyed upward.

[Action/Effect]

When the traveling chassis 1 is moved forward while driving each rotating part of the machine body, the rushes in the field begin to be weeded by the helical weeding devices 5 and 5' that have entered.

In this case, the spiral weeding device 5 acts on the stem culms in the stem culm passage M4 on the cut culm side, and performs the weeding action before the stem culms in the stem culm passage 4' on the uncut stem side.

Subsequently, the spiral weeding body 5' acts on the stem culm guided to the stem culm passage 4' on the uncut culm side to perform a weeding action.

In the process of weeding, the helical weeding device 5 on the cut culm side acts on the stem culm before the spiral weeding device 5' on the uncut culm side, so the loads are concentrated at the same time. It rarely takes.

In addition, since both spiral weed dividers 5 and 5' have different inclination angles, they do not rotate at the same height of the rush as shown in Fig. 1, causing damage to the stem culms. This is something that rarely happens.

In addition to that, a spiral weeding device 5' located on the uncut culm side
Since the angle of inclination is larger than that of the other, the stem culms to be harvested and the stem culms located outside of the stem culm passage 4 are reliably separated.

Claims (1)

[Claims] Two stalk culm passages are formed in front of the reaping device installed at a low position in the front of the traveling vehicle platform, separated by grass dividing support rods, and a spiral type grass dividing device is provided on each side of the stalk culm passage. A weeding device for a rush harvester, wherein the starting end of the weeding device on the cut culm side is located at the front and has a gentler inclination angle than the weeding device on the uncut culm side.
