Description

Detailed Description of the Invention "Industrial Application Field" The present invention picks up straw grass such as grass and straw scattered in a field with a pick-up section and forms it into a rolled bale in a bale forming chamber. This invention relates to a method for bundling a-rubella in which the twines that are transversely fed by a twine transverse feed guide are sequentially wound.

``Prior Art'' Conventionally, in this type of bale binding means, the twine cross-feed speed and cross-feed stroke were constant and could not be changed.

``Problems to be Solved by the Invention'' As a result, the straw grass that forms the bale with a long culm is tied in the same way as one with a short culm, and the bundling pitch of the twine is increased more than necessary. However, this method had the drawback of making the twine's tying stroke larger than necessary, which resulted in a large amount of waste, resulting in a large amount of twine being consumed.

"Means for Solving the Problems" Therefore, the present invention is configured to variably adjust at least one of the twine's cross-feeding speed and cross-feeding stroke in accordance with the culm length of the straw grass forming the bale. be.

"Function" According to the present invention, the bundling pitch or bundling stroke of the twine can be effectively adjusted depending on the length of the culm of the straw grass, thereby achieving maximum effective bundling with the minimum amount of twine consumption. This makes it possible to significantly improve work efficiency and economic efficiency.

When turned on, first the motor (48) is driven in low speed reverse direction to move the runner (62) to the right at low speed, and the switch (R7) is cleared and the -→S+(Q')) is turned on. When the motor (48) is driven in low speed forward rotation to move the launch (B2) leftward at low speed, and the switch (66) detects that the end of left movement has been reached. Move the launch (82) to the right again at low speed and move the runner (6)
2) reaches the cutter (58), the twine (39) is cut, and the binding switch (65) is turned off, so that the drive of the motor (48) is stopped.

In addition, the long culm side switching terminal (8) of the switching switch (69)

6) moves the launch (62) to the right at high speed again when it detects that the end of left movement has been reached, and when the launch (62) reaches the force lid (5B) and the twine (39) is cut off, the drive is stopped. It is configured to stop.

The present embodiment is constructed as described above, and the straw picked up by the pickup section (4) is carried into the bale forming chamber (17) by the vibrator (16) and formed into a rolled bale (A). and said binding device (
It is taken out laterally outside the machine from the opening of the rear side door (39), which has been bound by the method 1O), and during the binding work, the culm length of the 'a grass is short and the changeover switch is activated. (69) is switched to the terminal (Ha) side, each roll (
51) When the twine (39) fed out from (54) begins to wrap around the bale (A) and the tension turns on the binding clutch (85), the twine (39) fed out from (54) starts to wrap around the bale (A), and when the binding clutch (85) is turned on by the tension, the twine (39) is fed out from (54). (62) by Twine (39
) is first fed horizontally to the right at a low speed, and then as shown in (b) in the same figure.
The bale (A) is fed horizontally to the left as shown in FIG. ), this binding is completed. In this case, the bundling is done during bundling (L) over almost the entire length of the bale (A),
Moreover, it is performed at a fine pitch (1).

On the other hand, if the culm length of the straw grass is long, the changeover switch (69)
is switched to the terminal (139b) side, the twine (39) is traversed by the launch (62) at high speed during a short stroke between the switches (6B) and (H). In this case, as shown in Fig. 8, the bundling part (also) is smaller than that of short culm bundling, and the pitch (T
) becomes large (L>l, T>t).

In this way, in the case of long culm bundling, the bundling (text) is small and the pitch (T) is large, resulting in the consumption length of twine (39) for one bale (A) to be extremely short. As a result, economic efficiency can be significantly improved.

FIG. 9 shows another example of a modified structure, in which a single switch (67
a), the mounting position of the switch (67a) can be adjusted to the left and right, and the changeover switch (69
), a variable resistor (78) for controlling the speed of the motor (48) is interposed between the main switch (70) and the binding switch (B5).

Further, the forward rotation relay (7) is connected via the switch (87a).
9) to the bundling switch (85), and connect the normally open contact (79a) of the relay (79) and the normally closed runner left moving end detection switch (8B) to the switch (67a).
are connected in parallel. Then, the bundling switch (65) is connected to the forward/reverse circuit (80) (81) of the motor (48) via the normally open and normally closed contacts (79b) (79c) of the relay (79). The binding (L) and pitch (1) can be variably adjusted between the runner's right moving end detection switch (87a) and left runner's moving end detection switch (88). In this configuration, the number of detection switches (68) can be reduced and the circuit structure is simplified, and the binding (L) and pitch (1) can be easily and freely adjusted over a wide range.

Furthermore, in the above embodiment, Che7 (47) and Lunch (
B2) is connected by the locking pin (60) and the engagement hole (61), but the chain 7 (47) and the launch (62) are directly connected, and the motor (48) is driven at the folded end. By temporarily stopping the veil (A), the twine (39) may be wound multiple times at the left and right ends of the veil (A).

"Effects of the Invention" As is clear from the above embodiments, the present invention provides cross-feeding using a twine cross-feeding guide (62) on the outer periphery of a roll-shaped bale (A) formed in the bale-forming chamber (17). In the structure in which twine (39) is sequentially wound,
At least one of the traversing speed or the traversing stroke of the twine (38) is variably adjusted according to the culm length of the straw grass forming the bale (A), so Twine (39) binding pitch (1
) or the tying stroke (L) can be effectively adjusted, and as a result, the most effective tying can be achieved with the minimum amount of twine (39) consumed, resulting in remarkable improvements in work efficiency and economy. be effective.
