Abstract

PURPOSE:To smoothly rake in grain stalks, by increasing rotational speed of reel tines at an angle of sweepback in reaping against lodging and decreasing the rotational seed of the reel tines at an angle of advance in reaping against lodging. CONSTITUTION:The tip of an arm 78 is pivoted on an angle regulating cylinder 65 and rotated therewith to change the angle of reel tines 27. A speed change cam 76, together with the arm 78, is then rotated with a connecting lever 77 to move the speed change cam 76 itself in two directions and one of reel driving pulleys 75 in two directions and change the rotation of a raking in reel 20. In reaping against lodging, the cylinder 65 is contracted to change the direction of the reel tines 27 to the form of the figure 8 in KANJI. At this time, the rotational speed of the raking in reel tines 27 is increased. In reaping following lodging, the cylinder 65 is expanded to change the direction of the reel tines 27 to the form of the inverted figure 8 in KANJI. At this time, the rotational speed of the raking in reel 20 is reduced.

Better results can be expected by changing the situation. The reason why the desired effect cannot be obtained at the same time is because the rotation speed of the reel tines is slow. Increasing the rotation speed of the reel tines can be a significant improvement. Furthermore, the reason why the desired effect cannot be obtained at the same time is that the reel tines rotate quickly. Just slowing down the rotation speed of the reel tines can make a considerable improvement. In addition, the reason why the desired effect cannot be obtained in the case of opposite timing is that the angle of the reel tines is simply hanging down. Setting the reel tine angle to a receding angle can be a significant improvement. Similarly, when closing time,

When the state of
~3), it rotates so that the width becomes narrower, and when the height of the inclined surface 61 becomes the highest, it rotates to the minimum interval t to perform the culm focusing action, and when it reaches the non-working position (the 8Figure 4,

The weeds are separated, and the separated husk culms are harvested by the cutting blade 71, and the culm head is transported by the front stock head conveying device U. The former conveying device 69 and the rear ear tip conveying device 70 transfer the grain to the culm supply device η, and the culm supply device η supplies the grain to the threshing chamber 4 of the automatic feed type threshing device 3 for threshing.

Thus, the tine moving guide frame 42 has the inner periphery of the annular ring 43 attached to the scraping arm 47 by the mounting fitting 46.
Fit into the roller 45.45 attached to the side,
A rotating disk 44a rotating toward the inner circumferential side of the roller 45.45
Since the outer peripheries of the tine movement guide frame 42 are fitted, the position of the tine movement guide frame 42 is fixed relative to the reel frame 21 even if the reel frame 21 rotates.

The tine movement guide frame 42 is provided with a movement guide 59, and a guide roller provided on the reel frame 21 side is in contact with an inclined surface 61 of the movement guide 59.
4 is provided at the outer end of the slide rod 53, the guide roller 54 moves left and right along the inclined surface 61 of the moving guide 59 as the reel frame 21 rotates to move the slide rod 53 in and out. The slide par 52 is laterally moved by moving the slide rod 53 in and out, and the mounting plate 4B is rotated around the bin 48, thereby rotating the reel tines n between the maximum interval T and the minimum interval t.

In this case, the angle change adjustment frame 29 has its respective arm rods 3
The rotating ring (9) to which the base of the rotary ring (9) is fixed is fitted onto the roller 38 of the support plate g and rotates around the support plate g, thereby rotating the reel frame around the center X of the rotating ring (9). Since it rotates eccentrically with respect to the reel frame 21, when the support plate is rotated around the shaft tube by expanding and contracting the angle adjustment cylinder I, the angle adjustment frame will rotate as a whole with respect to the reel frame 21. The fourth arm rod 31 of the angle change adjustment frame moves up and down the horizontal axis A of the parallel link, rotates the link rod 5 on the horizontal axis A, and rotates the link rod 5.
rotates the rotating shaft portion, the rotating shaft portion rotates the mounting casing, and changes and adjusts the ground angle of the reel tines n.

The reel drive pulley is attached to the tip of the protruding shaft cutter, and the base of the inner reel drive pulley is
The base of the speed change cam is fitted, the outer end of the connecting rod is fixed to the tip of the speed changing cam, the inner end of the connecting rod is fixed to the arm 78, and the tip of the arm 78 is fixed to the above-mentioned angle. Since it is pivoted on the adjustment cylinder blade, when the angle adjustment cylinder 5 rotates the arm 78 to change the angle of the reel tines, the speed change cam rotates together with the arm 9 through the connection rod n, and the cam As a result, the speed change cam itself is moved in two directions (FIG. 4), and one of the reel drive pulleys is moved in two directions, thereby changing the rotation speed of the raking reel 20.

In this case, the relationship between the angle of the reel tine n and the rotational speed for raking is as follows: When mowing facing the culm of the field, the angle adjustment cylinder I is reduced, and the arm 78 is moved in the direction A in FIG. Since the reel tines n are rotated in the convex direction in FIG. 1 to change the angle, and at the same time the rotational speed of the scraping reel is increased, the culm can be completely raised.

When mowing, the angle adjustment cylinder b is extended, the arm 78 is rotated in the direction shown in FIG. 7, and the reel tines n are rotated in the opposite direction in FIG. 1 to change the angle. At the same time, since the rotational speed of the rake reel is slowed down, breakage of the culm, etc. can be prevented.

(Effects) Conventionally, combine harvesters in which the rotational speed of the rake reel can be changed are known.

It is also known that the reel tines of the rake reel are adjustable in forward and backward angles.

However, there is no known product that has both at the same time.

However, according to research, better results can be expected by changing the conditions of combine harvesters when it comes to head-cutting and tail-cutting. The reason why the desired effect cannot be obtained at the same time is because the rotation speed of the reel tines is slow. Increasing the rotation speed of the reel tines can be a significant improvement. Furthermore, the reason why the desired effect cannot be obtained at the same time is that the rotational speed of the reel tines is fast. Just slowing down the rotation speed of the reel tines can make a considerable improvement. Furthermore, the reason why the desired effect cannot be obtained at the same time is that the angle of the reel tines is simply hanging down. Setting the reel tine angle to a receding angle can be a significant improvement. Similarly,
The reason why the desired effect cannot be obtained at the same time is that the angle of the reel tines is simply hanging down. If you change the angle of the reel tines to the forward angle, you can improve it considerably.

However, according to the present invention, the rotational speed of the reel tine of the combine harvester can be changed freely, and the forward angle and the backward angle of the reel tine n of the raking reel can be freely adjusted, so that the reel can be mown in opposite directions. In this case, the reel tine n is set at a backward angle to increase the rotational speed, and when mowing, the reel tine n is set at a forward angle and the rotational speed is slowed down.This is used as a raking rule in a combine harvester, so these combinations are used. -Wj has a remarkable effect.
