JPH0488920A - Culm-separation apparatus of rush harvester - Google Patents

Abstract

PURPOSE:To surely separate culm of rush without damaging the rush culm by separating rush culms on a field in a specific state and raising the separated culms. CONSTITUTION:Rush culms on a field are separated with a side separation lever 5 at the unreaped side and the culm to be reaped is separated from the culm group with a side rotary grass-separation member 6. The separated culms are pushed toward the center with a middle rotary grass-separation member 7 placed at the back of the side separation member 6 and rotating in the same direction as the side separation member 6, supplied to a pair of raising paths 3, 3' and raised. Since a side of the separation member 6 is opened, there is no troubles such as clamping and damaging of the rush culm pushed according to the rotation of the grass-separation member 7.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a stem and culm dividing device in a rush harvester.

[Traditional technology]

The weeding device in the conventional rush harvesting machine is, for example,
As in the configuration example shown in Japanese Patent Publication No. 3-116619, the rotary weeding body on the cut culm side is in a position that is ahead in the advancing direction.

[Problem to be solved by the invention]

It is most undesirable for this type of rush to be damaged during harvesting, which causes a decrease in the commercial value of the product.

This tendency exists even in the conventional type described above, and when the - side of the rotary weeding body is mowing the grass, it is in a position where it comes into contact with the other rotary weeding body.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention takes the following technical measures. That is, a pair of right and left stem culm lifting devices M2.2' are provided at an angle in the front part of the vehicle body 1, and constitute at least two lifting passages 3.3'. A middle grass rod 4 is provided in front of the passageway 3.3', and a side grass rod 5.5' is provided on each side of the passage 3.3'. Among them, an oval-shaped side rotating weeding body 6 is provided, the starting end of which is supported on the weeding rod 5 located on the uncut culm side, and the terminal end is supported on the intermediate part of the pulling device 2 or the rear machine frame 15. The intermediate rotary weeding rod 4 is provided with a starting end thereof bearing an intermediate rotary weeding body 7 located at a position set back from the side rotary weeding body 6, and the intermediate rotary weeding rod 7 and the side rotary weeding body are connected to each other. Reference numeral 6 denotes a stem and culm separating device in a rush harvester configured to rotate in the same direction.

[Action/Effect]

Next, the action and effects will be explained.

Reaping work is started by moving the vehicle body 1 forward while driving each rotating part.

Then, the rush stem frame in the field first starts to be weeded by the preceding lateral grass rod 5 on the uncut culm side, and is moved to the starting end of the lateral rotating weeding body 6 that is rotating in the direction of the arrow. Uke is inherited and separates the stem culm to be harvested from the stem culm group.

At this time, the rush stem frame is in a state where the middle rotating weeding body 7 is retreating from the side rotating weeding body 6 in the direction of movement and the sides of the side rotating weeding body 6 are open. Even if the partial weeding body 7 is pushed toward the center by rotation, it will not be pinched and damage can be prevented.

In this way, as the car body 1 moves forward, the rush stem frame is further divided by the weeding action and is supplied to the two lifting passages 3.degree. 3', where it is subjected to the pulling action.

In this way, the stem culm that has been raised is removed by the reaping device 13.
The upper part of the plant is harvested by the upper conveying device 9, and the plant head is lifted laterally by the plant conveying device 14 and supplied to the grading device 10.

As described above, the present invention provides a pair of left and right stem culm lifting devices at an angle at the front of the vehicle body to form at least two lifting passages, and a pair of stem culm lifting devices located in front of the two pulling passages. An intermediate grass rod is provided between the passages, and side grass rods are provided on each side of the passage, and the starting end is supported by the grass rod located on the uncut culm side of the side grass rods, and the terminal end is An oval-shaped side rotary weeding body is provided, the part of which is supported on the intermediate part of the pulling device or the rear machine frame, and the starting end of the intermediate weeding rod is located at a position set back from the side rotary weeding body. The middle rotating weeding divider is mounted on a bearing, and the middle rotating weeding divider and the side rotating weeding divider are configured to rotate in the same direction. It has an excellent feature that it can be divided into plants.

【Example〕

The vehicle body 1 is configured to be able to run on crawlers 8, and includes an upper conveying device 9 for conveying the reaped stem culms, a scavenging device [10,
A driver's seat 11 and a carrier 12 are provided at the rear.

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

A pair of culm lifting devices 2.2' are provided at the front of the vehicle body 1, each forming a pulling passage 3.3' for pulling up one culm row.

The intermediate grass rod 4 is provided at an intermediate position N (boundary) in front of the above-mentioned lifting passage 3.3'. The side part grass rod 5.5' is attached to the side part of the middle grass rod 4 so as to be slightly advanced from the middle grass rod 4.

The side rotary weeding body 6 is made of an elliptical pipe material and has a conical starting end supported by the side grass rod 5 on the uncut culm side. The side rotary weeding body 6 is tilted rearward, and its terminal end is supported by an intermediate portion of the stem culm pulling device 2.

The middle rotary weeding body 7 has a diameter smaller than that of the side rotary weeding body 6, has a conical starting end bearing on the intermediate weeding rod 4, extends rearward in an inclined shape, and has a terminal end bearing on the rear machine frame 15. ing.

As shown in the side view of FIGS. 1 and 2, the side rotating weeding body 6 has its starting end positioned ahead of the starting end of the middle rotation weeding body 7 in the forward direction of the vehicle body. There is.

The two rotary weeding bodies 6 and 7 may be in the state shown in FIG. 1 or in 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 vehicle body 1 is rotated while driving each rotating part.
Move forward and start reaping work.

Then, the rush stem frame in the field first starts to be weeded by the preceding lateral grass rod 5 on the uncut culm side, and is moved to the starting end of the lateral rotating weeding body 6 that is rotating in the direction of the arrow. Uke is inherited and separates the stem culm to be harvested from the stem culm group.

At this time, the rush stem frame is in a state where the middle rotating weeding body 7 is retreating from the side rotating weeding body 6 in the direction of movement and the sides of the side rotating weeding body 6 are open. Even if the partial weeding body 7 is pushed toward the center by rotation, it will not be pinched and damage can be prevented.

In this way, as the car body 1 moves forward, the rush stalk frame is further divided by the weeding action and is supplied to the two raising passages 3.3', where it is subjected to the raising action.

In this way, the stem culm that has been raised is removed by the reaping device 13.
The upper part of the plant is harvested by the upper conveying device 9, and the root is lifted laterally by the root conveying device 114 and supplied to the grading device 10.
