Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to reel tines in a combine harvester.

(Prior Art) Conventionally, it is known that the rotation locus of the reel tines of a scraping reel provided at the tip of a combine harvester is 0 when viewed from above and parallel to the direction of movement of the machine.

(Problems to be Solved by the Invention) The reel tines of the above-mentioned known raking reel act only in a planar view and in a straight line when viewed from the front, and as a result, the reel tines tend to cause problems when lodging, resulting in poor performance (particularly when cutting in the opposite direction). .

In other words, at the start of the raking action, the spacing is too narrow and the culm may remain raked, but when transporting, the raking action is widened and the raked grain culm is raked backwards, so the focusing action is not effective. Doesn't play.

Therefore, the present invention improves the raking efficiency of the reel tines by rotating them in a direction transverse to the direction of travel.

(Means for Solving the Problem) Therefore, the present invention provides a combine harvester for harvesting and threshing grain by raking grain culms using a raking reel tine, in which the reel tine rotates in a transverse direction with respect to the traveling direction. This is the reel tine for a combine harvester.

In the angle change adjustment frame device, the rotary ring 30 fixed to the base of each arm rod 31 is connected to the roller 38 of the support plate n.
By fitting into the support plate and rotating around the support plate, the rotation ring 30 rotates eccentrically with respect to the reel frame 21 with the center X of the rotation ring 30 as the rotation center. Therefore, since the support plate itself does not rotate, when the support plate is rotated around the shaft cylinder, the entire angle change adjustment frame 29 is moved up and down with respect to the reel frame 21, and the arms of the angle change adjustment frame 29 are moved up and down relative to the reel frame 21. The rod 31 moves the parallel link up and down that horizontal axis, and the horizontal axis 34

(effect) Next, we will discuss the effect.

The present invention has the above configuration, and when the machine is run by the traveling device 2, the grain culms in the field are raked by the reel tines η of the rotating raking reel 20.

The root of the grain culm is separated between the cutting bodies, and the divided grain culm is cut by the cutting blade 71. transport,
Next, the rear stock head transport device 69 and the rear stock head transport device 170
Accordingly, the grain culm is transferred to the grain culm supply device η, and the grain culm is supplied to the threshing chamber 4 of the automatic feed type threshing device 3 by the grain culm supply device n, and threshed.

In this case, the tine moving guide frame C has the inner periphery of the annular ring 43 attached to the scraping arm 4 by the mounting fitting 46.
A rotating disk 44 that is fitted into a roller 45.45 attached to the 7 side and rotates toward the inner peripheral side of the roller 45.45.
Since the outer peripheries of a are fitted, even if the reel frame 21 rotates, the tine movement guide frame 42 remains fixed in position with respect to the reel frame 21.

The tine movement guide frame 42 is provided with a movement guide 59 , a guide body provided on the reel frame 21 side comes into contact with the slope 61 of the movement guide 59 , and the guide body 54 is connected to the outer end of the slide bin 53 . Since the guide body 8 is provided in the movable guide 5 by the rotation of the reel frame 21,
The slide bin 53 is moved in and out by moving in the left and right direction along the inclined surface 61 of No. is rotated between a maximum distance T and a minimum distance t.

In this case, as shown in FIG. 8, the inclined surface 61 of the moving guide 59 is formed so as to gradually increase in height and thickness and return to the original height. Slope 6
1 is low (FIG. 8 0, FIG. 9 O), the reel tines n and 27 are rotated laterally to the maximum interval to start the raking action, and the inclined surface 61 is When the grain height and thickness are gradually increased (Fig. 8 O-3, Fig. 9 O-3), the reel tines n and 27 are rotated laterally to the minimum interval t, and the grain culm focusing action is performed. let Then, when the reel tines n and 27 reach the non-operating position due to the rotation of the reel frame 21 (FIGS. 8 and 4), the inclined surface 6! Ha returns to its original height and immediately changes the width of the reel tines 27.27 to the maximum interval T.

Therefore, since the reel tines n, 27 rotate in the left and right directions in the front view while making a circular motion in the side view, the locus of the reel tines n, 27 can be made circular in the action area from the front view, and the lodging grain The ability to raise the culm is improved.

Further, since the reel tines n and 27 can be raked in the direction of grain culm merging, the rearward conveyance performance is also improved.

Further, when the reel tines n and 27 are moved to the non-operating position, they are immediately rotated to the maximum interval T, thereby preventing the grain culm from being rotated or pulled out.

(Effects) Conventionally, it is known that the rotation locus of the reel tines of the scraping reel provided at the tip of the combine is parallel to the direction of movement of the machine when viewed from above.

The reel tines of the above-mentioned known raking reel act only in a straight line in a plan view and in a front view, and therefore, the reel tines tend to be raised when the reel is laid down, resulting in poor performance (particularly in facing cutting).

In other words, at the start of the raking action, the spacing may be too narrow and the grain culms may remain stuck, and when conveying, the spacing is too wide and the raked grain culms are raked backwards, resulting in a focusing action. do not.

However, the present invention provides a combine harvester for harvesting and threshing by raking grain culms using reel tines n of a raking reel, in which the reel tines are configured to rotate in a transverse direction with respect to the direction of travel. Because it is a thing.

Since the reel tines 27 and 27 rotate in the left and right direction while making a circular motion in side view, the reel tines a and 2
The locus of No. 7 can be made circular in the action area, and the raising performance for lodging grain culms can be improved.

Further, since the reel tines 27, 27 can be raked in the direction of grain culm merging, the rearward conveyance performance is also improved.

Furthermore, when the reel tines 27 and 27 move to the non-operating position, they are immediately rotated to the maximum interval T.
Prevents grain culm from turning around and being pulled out.
