[0002]

2. Description of the Related Art Conventionally, in a rush harvesting machine, as disclosed in, for example, Japanese Patent Application Laid-Open No. 6-296417, a pair of squeezing rollers are used to remove lint that protrudes toward the end of the rush plant. After being unwound, the long culm was discharged into the field as it was.

[0003]

Therefore, in the past, the waste rush released into the field remains a long culm.
In the rotary work for later plowing into the field, there was a possibility that troubles such as the difficulty of plowing and the tangs of long culm entangled with the rotary shaft might occur.

The present invention has been made in view of the above circumstances, and makes it easy to post-process waste rush discharged into a field, and to easily perform maintenance work in a waste crushing device for doing so. The purpose is to provide a rush harvester that can be used.

[Means for Solving the Problems]

(Structure) The rush harvester according to claim 1 of the present invention is configured so that waste rush protruding toward the end of the rush of conveyed rush is pinched and pulled out by a pair of rotary rollers driven to rotate. On the discharge side of the dust roller, a litter shredding device is provided for sequentially cutting the discharged lint from the transport end, and the litter shredding device is cut off the discharged lint. A fixed blade body received at a position, and a rotary blade body driven to rotate around an axis substantially parallel to the rotation axis of the cutting roller and cutting in cooperation with the fixed blade body, A fixed blade base for supporting and fixing the body is cantilevered to a body fixing portion on the upper side of the transport of the rush so that the lower side of the transport extends sideways.

(Operation) According to the first aspect of the present invention, the waste rush is pulled out and carried out by a pair of squeezing rollers, and the carried waste rush is sequentially cut from its transport end. A fixed blade and a movable blade are provided. Then, the cutting waste is released to the field. Furthermore, since the fixed blade base for supporting and fixing the fixed blade body is cantilevered to the body fixing portion on the upper side of transport of the rush group with the lower side of the transport extending sideways, the fixed blade base is supported in the transport direction of the rush group. Even if cutting debris or the like moves to the rear end of the fixed blade body or fixed blade base, which is the lower end, there is no such thing at the rear end that catches the cutting debris or the like. This prevents cutting waste from staying for a long time on the fixed blade body and the rear end of the fixed blade base.

(Effects) Therefore, according to the configuration of the first aspect of the present invention, the debris is shredded by the cooperation of the fixed blade and the rotary blade, and the cut debris is cut off. Since it is released to the field, it is possible to eliminate the problem caused by releasing waste rush into the field while keeping the long stem state,
Since cutting wastes such as on the fixed blade body and the rear end of the fixed blade base do not stay for a long time,
It has been possible to solve such a problem that a cutting defect occurs due to such a long stay of cutting wastes.

(Structure) The rush harvester according to claim 2 of the present invention is the rush harvester according to claim 1, wherein the end position of the action range of pulling out the scraps of the dust roller is determined by the cutting action range of the rotary blade body. It is characterized in that it is set to be better in the rush group transport direction than the end position of.

(Operation) According to the configuration of the second aspect of the present invention, the end position of the action range of pulling out the waste roller from the dust roller is set closer to the rush group transport direction than the end position of the cutting action range of the rotary blade body. Because the skill set at the side is set
Even if the cutting waste rushes on the lower edge of the fixed blade body in the direction of transport of the rush, the cutting waste rushing on the end of the blade is located on the lower edge of the rotating blade. It is more likely to be scraped by the body.

(Effects) Therefore, according to the configuration of the second aspect of the present invention, it is possible to further prevent the cutting waste and the like from staying at the end portions of the fixed blade body and the fixed blade base.

On the side of the driving section of the self-propelled body,
The loading platform 10 for storing the rush bundles from the binding device B is provided so as to be able to be dumped by the dump cylinder C2, thereby constituting a riding type rush harvester.

The transport section 7 includes the endless rotating belt 3 located on the rear side of the raising device 2, and a pair of upper and lower lateral feeders located below the endless rotating belt 3 and located on the rear side of the raising device 2. Endless rotating belts 11, 11, a blower 12 located between these laterally feeding endless rotating belts 11, 11, this blower 1
2 is constituted by endless endless turning belts 14 and 15 arranged side by side in the fuselage receiving table 13 located on the lateral side of FIG. The endless rotating belt 3 clamps the stem side of the cutting rush from the cutting device 4 and conveys it to the rear of the machine. A pair of laterally feeding endless rotating belts 11 and 11 move the root side of the cutting rush plant where the endless rotating belt 3 clamps the stem.
Are fed laterally toward the rush receiving table 13 by these locking and conveying claws. When this stock side reaches the side of the blower port 12a of the blower 12, the wind from the blower port 12a blows up the stocker side, and the rear feed endless rotating belts 14, 15 located on the rush receptacle 13 are moved. The rear feeding endless rotating belt 14 is positioned on the side closer to the blower 12 and is locked by the locking and conveying claw. Then, the post-feeding endless rotation belt 14 lifts the root side of the cutting rush onto the upper surface of the rush receiving tray 13 and places the sorting end of the sorting device 5 located above the front end of the rush receiving tray 13 endlessly. Belt 16 and rush basin 13
To the top of At this time, the transport guide 17 receives and acts on a stem portion between the endless rotating belt 3 and the backward feeding endless rotating belt 14 of the cutting rush, and the stem tip side of the transport guide 17 of the cutting rush faces the machine body up and down. In this state, the root side of the stock relative to the transport guide 17 is in a sideways-down attitude on the rush receiving table 13, so that the cut rush grass has a curved bending position as a whole at a position where it comes into contact with the transport guide 17. In this bent posture, the endless rotating belt 3 further clamps and conveys the tip side to the rear, and feeds the stock side backward to the endless rotating belt 14.
