Abstract

(57) [Abstract] [Purpose] A cutting blade is provided below the cutting tool installation pipe so that the cutting position can be freely changed, and a guide for guiding foreign matters below the cutting blade is provided below the pipe and in front of the cutting blade. In the reaping harvester arranged in the above, the guide is improved so that unevenness of the culm length of the cutting culm caused by entering the lower part of the guide can be suppressed as much as possible and the guide can be easily assembled. [Structure] A rear end side of a spring wire 11 forming a guide is attached to a lower portion of a cutting blade 5, and a front end side of the spring wire 11 is inserted into a pipe 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a cutting blade below a weeding tool mounting pipe so that it can be vertically changed so that it can be switched between a high cutting state and a low cutting state. TECHNICAL FIELD The present invention relates to a mowing section of a mowing harvester in which a guide for guiding foreign matters below a cutting blade is arranged below the pipe and in front of the cutting blade so as not to get between the pipes.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 7 and 8, a guide 23 made of a plate is fixed to a pipe 10, and a lower edge rear end 23a of the guide 23 is positioned below a cutting blade 5 located at the lowermost position. Had been placed.

[0003]

However, FIG. 7 and FIG.
As shown in, when the cutting blade 5 is positioned high, the guide 23
Since the lower edge rear end 23a of the cutting stalk is located at an unnecessarily low position, the root 13 of the cutting stalk that has entered below the guide 23 is tightly bent, and the length of the cutting stalk is shortened. It was one of the causes of uneven culm length. An object of the present invention is to improve the guide so that unevenness of the culm length of the cutting culm due to the entry under the guide can be suppressed as much as possible and that the guide can be easily assembled.

[0004]

The characteristic construction of the present invention is that a cutting blade is provided below the weaving tool mounting pipe so that the cutting blade can be vertically moved, and a guide for guiding foreign matter to the lower side of the cutting blade is provided below the pipe. In the harvesting machine arranged in front of the cutting blade, the rear end side of the spring wire forming the guide is attached to the lower part of the cutting blade, and the front end side of the spring wire is inserted inside the pipe.

[0005]

In other words, the rear end side of the spring wire forming the guide is attached to the lower part of the cutting blade so that the position of the spring wire can be changed in the same direction as the vertical position of the cutting blade is changed. Regardless of the vertical position of the blade, the root of the cutting culm that has entered the lower part of the guide is bent due to the spring wire being unnecessarily lowered as in the above-mentioned conventional technique, and the cutting culm is cut tightly. You can avoid the inconvenient situation that the length of
It is possible to suppress uneven culm length of cut culms as much as possible. Moreover, since the rear end side of the spring wire is attached to the lower part of the cutting blade, the front end side of the spring wire is inserted into the pipe and the spring wire is elastically deformed to change the vertical position. Easy and quick to execute.

[0006]

As a result, the culm lengths of the cutting culms can be made as uniform as possible, and the guides for that purpose can be easily assembled, and the reaping section of the reaper harvesting machine that is more excellent in terms of cutting performance and production can be provided. It became so.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a mowing section 2 is provided at a front portion of a traveling vehicle equipped with a crawler type traveling device 1 so as to be capable of swinging up and down, and a weeding tool 3, a planted culm is provided in the mowing section 2. Raising device 4,
The cutting blade 5, the stocker side holding and conveying device 7 for sending the slaughtered culms to the threshing unit 6 and the tip side locking and conveying device 8 are provided, and the grain culm from the reaping unit 2 is laterally attached to the threshing device 6 mounted on the traveling vehicle body. A feed chain 9 that holds and conveys in a tilted posture is provided to configure a self-removing combine. As shown in FIGS. 2 to 4,
A cutting blade 5 is provided below the pipe 10 to which the weeding tool 3 is attached so that the vertical position can be freely changed by, for example, a long hole and bolts and nuts, and the cutting blade 5 can be switched between a high cutting state and a low cutting state. . A spring wire 11 such as a piano wire that forms a guide for guiding foreign matter to the lower side of the cutting blade is held at the rear end side by a metal fitting 1
2 and bolts are attached to the lower part of the cutting blade 5 and the front end side is inserted into the pipe 10 so that foreign matters such as weeds do not enter between the cutting blade 5 and the pipe 10. The position of the spring wire 11 is also changed in the same direction as the vertical position of the cutting blade 5 is changed so that the spring wire 11 does not become lower than necessary regardless of the vertical position of the cutting blade 5. The bent state of the root 13 of the cutting culm that has entered below the line 11 is made as loose as possible so that the culm lengths of the cutting culms can be made uniform. A bent portion 11a is formed at the rear end of the spring wire 11, and the spring wire 11 is prevented from rotating by abutting the cutting blade 5 and the bent portion 11a, and a recess formed in the fixed blade of the cutting blade 5 The spring wire 11 is engaged with 14 to prevent the spring wire 11 from being laterally displaced.

As shown in FIGS. 5 and 6, in order to form the raising device 4, a chain 16 having a raising claw 15 attached so that it can be raised and lowered is wound around a roller 17 on the lower end side and attached to the roller 17. Scraper 1 for removing dirt and straw debris
8, a nozzle 20 connected to an oil supply hose 19 is fixed to a mounting member 21 different from the scraper 18, and an extension hose 22 for guiding lubricating oil from the nozzle 20 to the roller 17 is provided.

[Other Embodiments] The specific structure for attaching the cutting blade 5 so as to freely change the vertical position can be changed appropriately. Spring wire 11
The specific configuration in which the rear end side is attached to the lower part of the cutting blade 5 can be selected as appropriate.

It should be noted that although reference numerals are given in the claims for convenience of comparison with the drawings, the present invention is not limited to the structures of the accompanying drawings by the entry.
