Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a stalk-culm weeding device in a rush harvester.

(Prior art)

Conventional weed harvesters have a weeding device, for example, as disclosed in
As in the configuration example disclosed in JP-A-63-116619, the rotating weeding body on the cut culm side is at a position preceding in the traveling direction.

[Problems to be solved by the invention]

This type of weed is least likely to be damaged during the harvesting operation, causing a decrease in commercial value as a product.

Even in the above-mentioned conventional type, there is a tendency to be such that, when weeding is performed by one rotating weed body, the other rotating weed body is in contact with the other rotating weed body.

[Means for Solving the Problems] The present invention employs the following technical means to solve the problems described above. That is, a pair of left and right stem and stem raising devices 2, 2 'are provided at the front of the vehicle body 1 at an angle to form at least two raising passages 3, 3', and the two raising passages 3, 3 'are formed. ′, A middle weeding rod 4 is provided at the boundary between the passages 3 and 3 ′, and side partial weeding rods 5 and 5 ′ are provided on both sides thereof. Among them, the weeding rod 5 located on the side of the uncut culm has a weeding rod 5 with a start end bearing and an end part raised to the middle part of the device 2 or the elliptical side rotating weeding body 6 bearing on the rear machine frame 15. The middle weeding rod 4 is provided with a middle rotating weed body 7 whose starting end is retreated from the side rotating weeding body 6 as a bearing, and the middle rotating weeding body 7 and the side rotating weeding body are provided. Reference numeral 6 denotes a stem and stem weeding device in a grass harvester that is to be driven to rotate in the same direction.

[Action / Effect]

 Next, the operation and effect will be described.

The body 1 is advanced while driving the rotating parts to start the mowing operation.

Then, the grass stalk culm in the field first starts weeding by the leading side partial grass rod 5 on the uncut culm side, which is located at the beginning of the side rotating weed body 6 rotating in the direction of the arrow. Separate the stem culm that is inherited and is to be harvested from the stem culm group.

At this time, the turf stalk culm is in a state in which the middle rotating weed body 7 is retracted from the side rotating weed body 6 in the traveling direction and the side of the side rotating weed body 6 is open. Even if it is pushed to the center side by the rotation of the partial rotation weed body 7, damage can be prevented without being pinched.

In this way, the grass stem and culm progresses in weeding as the vehicle body 1 moves forward, and is supplied to the two raising passages 3, 3 'to be raised.

In this way, the stems and stems caused by the reaper 13
Then, the upper part is clamped by the upper conveying device 9 and the stock is lifted to the side by the stock conveying device 14 and supplied to the rinsing device 10.

As described above, according to the present invention, a pair of left and right stem and stem raising devices are provided at the front of the vehicle body at an angle to constitute at least two rising passages, and a front portion of the two rising passages is provided. In addition, a middle weeding rod is provided between the passages, and side partial weeding rods are provided on both sides of the middle weeding rod. An intermediate portion of the raising device, or an elliptical side rotation weed body bearing on a rear machine frame is provided, and the middle weeding rod has a start end retracted from the side rotation weed body. And the side-rotating weeds are configured to rotate in the same direction, so that the stems and culms are not damaged. It has excellent characteristics that can germinate in vegetation.

〔Example〕

The vehicle body 1 is configured to be able to travel by a crawler 8,
An upper conveying device 9 for conveying the cut stems, a drilling device 10, a driver's seat 11, and a carrier 12 at a rear portion are provided.

Reference numeral 13 denotes a mowing device, which is provided at a low position at the front of the vehicle body 1. Reference numeral 14 denotes a stock transfer device.

The stem and stem raising devices 2 and 2 ′ are provided in a pair at the front of the vehicle body 1, and constitute raising passages 3 and 3 ′ for respectively raising one stem and stem row.

The middle weeding rod 4 is provided at an intermediate position (boundary) in front of the raising passages 3, 3 '. The side partial grass rods 5 and 5 ′ are attached to the side of the middle grass rod 4 so as to be slightly advanced from the middle grass rod 4.

The side-rotating weeding body 6 uses an elliptical pipe material to support the conical starting end of the side portion grass rod 5 on the uncut culm side. And this side rotation weeding body 6 is made to incline backward, and the terminal part is provided in the middle part of the device 2 for raising the stem and stem.

The middle rotating weed body 7 is made smaller in diameter than the side rotating weed body 6, the conical starting end is supported by the middle weeding rod 4, the rear end is extended in an inclined shape, and the end part is supported by the rear machine frame 15. ing.

Then, the starting part of the side rotation weeding body 6 is shown in FIG.
As shown in the side view of FIG. 2, the intermediate rotation weed body 7 is configured at a related position that precedes the leading end of the middle rotation weed body 7 in the vehicle forward direction.

Note that the two rotating weeds 6 and 7 may be in the state shown in FIG. 1 or the state shown in FIG. 2 at the end as long as the relative positions at the start end are as described above.

With the above configuration, the body 1 is moved forward while driving the rotating parts to start the mowing operation.

Then, the grass stalk culm in the field first starts weeding by the leading side partial grass rod 5 on the uncut culm side, which is located at the beginning of the side rotating weed body 6 rotating in the direction of the arrow. Separate the stem culm that is inherited and is to be harvested from the stem culm group.

At this time, the turf stalk culm is in a state in which the middle rotating weed body 7 is retracted from the side rotating weed body 6 in the traveling direction and the side of the side rotating weed body 6 is open. Even if it is pushed to the center side by the rotation of the partial rotation weed body 7, damage can be prevented without being pinched.

In this way, the grass stem and culm progresses in weeding as the vehicle body 1 advances, and is supplied to the two raising passages 3, 3 'to be raised.

In this way, the stems and stems caused by the reaper 13
Then, the upper part is clamped by the upper conveying device 9 and the stock is lifted to the side by the stock conveying device 14 and supplied to the rinsing device 10.
