Description

[Detailed description of the invention] Conventionally, a weed culm provided at the front of the cutting blade separates the grain culms that are inside the weeding body to be reaped and the grain culms that are outside and remain as uncut grain culms. Although the grain culms were separated into left and right sides, the lodging grain culms were often intertwined, and it was not possible to create a sufficient division area using only the above-mentioned crop culms.

In order to improve this drawback, even if a grain culm guide rod was fixed to the front part of the culvert that directed diagonally backward, the effect within the culver was insufficient because it merely pushed the tangled grain culms apart as if to squeeze them. .

The present invention moves the grain culm guide rod forward together with the machine body, and repeats the action of forcibly pushing it forward to forcefully push it apart and retreating to break it apart, thereby removing the grain culms that have collapsed and become entangled. However, it is an object of the present invention to provide an auxiliary narrow guide for a reaper that can easily and reliably move the grass into the cutting draft while loosening the grass. In the reaper, a substantially horizontal operating rod that moves back and forth is projected forward from the lower part of the grass cutting body on the uncut land side, and the front end of the grain culm guide rod that rises diagonally rearward is connected to the front end of the operating rod. It is characterized in that it is fixed to the front part so that the grain guide rod moves in parallel in the front and back direction while maintaining a constant tilted posture.

The embodiments shown in the drawings will be explained below.
Reference numeral 1 denotes a transmission case for a reaping and binding machine, which has a pair of left and right wheels 2, 2 pivotally supported at the bottom, an engine 4 mounted on a frame 3 at the rear, and a cutting blade 5 at the front.
A reaping device 8 consisting of a weed splitting body 6 and a grain culm pulling body 7 is mounted on a cylindrical frame 10 in which a mounting frame 9 and a transmission shaft are housed, and a binding device is attached to the side of the cutting blade 5. 11 are provided.

Further, a vertical cylindrical frame 1 stands up from the rear part of the reaping device 8 and is connected to the front end of the cylindrical frame 10.
The vertical axis in 0a drives the bundling device 11 and the cutting blade 5 at the lower part, and drives the grain culm lifting body 7 at the upper part. Although not shown, the cutting blade 5 is fixed to the front end of the box frame 12 from the front of the box-shaped frame 12.
A narrow guard similar to the conventional one is provided over the upper side.

An operating rod 13 made of a square rod is inserted into the box-shaped frame 12 on the uncut field side so as to be slidable back and forth, and the front end of the operating rod 13 has a shape as shown in FIG. 1a when viewed from the side. The base of the auxiliary narrow guide 14, which rises diagonally rearward along the grain culm pulling body 7 at intervals and extends rearward at intervals outward as shown in FIG. 1b in plan view, is fixed. It has been done.

The base of the auxiliary narrow guide 14 is pushed out and biased by a bullet 16 whose rear end is received by a spring receiver 15 on the box-shaped frame 12. The driven wheel 7 of the grain culm raising body 7 is formed in the driven part 13b having the hole 13a.
A spur gear 7c is attached to a diagonal shaft 7b hanging from a, and a spur gear 17 is attached to a diagonal shaft 17b on an operating rod 13.
a, and the bevel gear 1 is engaged with the bevel gear 1 by the oblique shaft 17b.
7c, 17c, the vertical shaft 18 has a crank arm 19a and a crank pin 19b, and the crank pin 19b is connected to the passive part 13b.
The oblique shafts 7b, 17b, the spur gears 7c, 1
7a, crank arm 19a and crank pin 1
9b and the like constitute a longitudinal drive device.

In the above-mentioned reaping and tying machine, when the body is moved forward while driving the reaping device 8 and the tying device, the erect grain culm is guided by the narrow guide and the auxiliary narrow guide 14, and the weeding body 6 moves the plant base further on both sides. push it apart.

At this time, the crank pin 19b rotates while being inserted into the elongated hole 13a due to the rotation of the chain in the grain culm pulling body 7, and as the operating rod 13 moves rearward, the bomb 16 is compressed. The auxiliary narrow guide 14 strongly pushes the erect grain culms apart when moving forward, and when it retreats, it rapidly opens the pushed out grain culms and separates them, causing them to move forward and backward. While repeating the reciprocating movement, the grain culms are guided one by one to the upper part of the grain culm pulling body 7, and during this time even the grain culms that have fallen down and become entangled are loosened to the ears as shown in Fig. 4. At the same time that the grain culms are placed neatly in the dividing draft, they are raised by the grain culm pulling body 7, the root part is harvested by the cutting blade 5, and when the reaped grain culms are guided to one side of the machine body by the guide plate, the binding device 11 binds them. and release it laterally.

Next, another embodiment of the longitudinal drive device will be explained with reference to FIGS. 5 and 6.
3 extends to the side of the cutting blade 5 and is provided with a horizontal hole 21 at the rear, and a rod-shaped cam 23 having an inclined part 22 in the middle is provided at the end of the movable blade 5a of the cutting blade 5.
is provided protrudingly, and this cam 23 is inserted into the hole 21, so when the movable blade 5a reciprocates left and right, the operating rod 13 continuously moves back and forth, and the auxiliary narrow guide 14 moves as described above. As in the example, it reciprocates back and forth while being pushed and biased by the bullet 16, thereby loosening and weeding even the grain culms that have fallen down and become entangled.

As described above, the present invention is a reaper in which a grass cutting body and a grain culm pulling body are provided at the front part of the cutting blade, in which a substantially horizontal operating rod that moves back and forth is moved forward from the lower part of the grass cutting body on the uncut field side. The front end of the grain stem guide rod that protrudes and stands up diagonally rearward is fixed to the front part of the operating rod, and the grain stem guide rod moves in parallel in the front-back direction while maintaining a constant tilted posture. With this structure, even if the grain culm to be harvested is lying down, the auxiliary narrow guide 14 will have its front end thrust between the grain culm plants in its forward movement to reliably separate the grain culms from the base, and will also move the grain culms diagonally backward. In a certain posture, the stock side and the panicle side are forcibly pushed apart to the same extent, and when they subsequently retreat, they maintain a certain tilted posture, which causes them to fall down and become entangled. When the auxiliary narrow guide 14 moves back and forth to weed the grain culms, the heavy ears of the grain culms are greatly stirred up and thrown in the direction of falling down, or the fixed member or the backward stroke is changed to the forward stroke. Grass can be easily and orderly separated into the inside and outside of the grass cutting body while preventing grains from colliding with the auxiliary narrow guide 14 and falling off.
