[0003]

[Problem to be solved by the present invention]
The pick-up unit picks up materials such as grass and straw scattered in the field, forms a roll-shaped bale in the bale forming room, and binds the string from the string roll box to the bale forming room by the binding device. And wrap the string around its outer periphery,
In that case, the repetitive output by pressing the sub-roller against the main roll should be stronger than the braking force of the string brake, and the string may break at the start of the reeling. Therefore, the present invention has been conceived especially for the purpose of preventing the above-described string breaking at the start of the string feeding.

[0004]

Accordingly, in order to achieve the object described in the preceding paragraph, the present invention provides a bale forming chamber for forming a bale by providing curved main and sub conveyors in opposition to each other and a front of the bale forming chamber. And a binding device for winding a string around the veil, a string brake is provided between the string roll box for accommodating the string and the binding device, and the string is passed through the strap brake in the binding device. was introduced into the bale forming chamber than between the main and sub feed roll of forming a rolled bale in roll baler for wound around the cord on the outer periphery thereof, said
The secondary feeding roll can be pressed against and separated from the main feeding roll.
At the same time, the braking force of the brake can be changed freely.
And the secondary feeding roll and the moving piece for changing the braking force
Works in conjunction with the work clutch lever for string winding processing
The movement of the clutch lever causes the brake
-The secondary feeding roll is the main feeding roll at the same time
To the work clutch lever
Operation causes the sub-feeding roll to separate from the main feeding roll
At the same time, the braking force of the brake is strengthened.
It was .

[0005]

[Function] The work clutch lever is operated in the entering direction.
And the union device is fed out of the string roll box
Is wrapped around the outside of the bale,
When the string is extended by the bundling device, the braking force of the string brake
At the same time as the weakening, the secondary feeding roll presses against the main feeding roll,
The repetitive power generated by this crimping causes the cord to pull a large amount of tension.
Veiled shape to prevent loosening and smoothness
The bale is fed to the forming chamber, and the bale can be suitably wound. one
On the other hand, when the work clutch lever moves in the
When the feeding roll separates from the main feeding roll,
The braking power of the rake increases. With this, the secondary operation roll
The feeding force by pressing the main feeding roll and the main feeding roll is strong braking force.
It does not act on the string in the state of being given. Therefore,
The work clutch lever moves to the entry side or the
No matter if it is made, the feed-out force of the string due to the pressing of the sub-feeding roll
String is severed due to the strong
The elephant is definitely stopped.

From 1) to (52), the transmission is interrupted or interrupted, and the interruption by the pawl clutch is performed by the pressure of the completed belt (A) completed in the belt forming chamber (3). ) Is performed via the wire (53) by changing the attitude to the release side indicated by the arrow (a) with the input shaft (23) as a fulcrum.

The binding device (6) is provided between the upper ends of the main conveyor (1) and the sub-conveyor (2). As shown in FIG. 3) A binding case (54) for connecting and fixing between both side plates, a moving chain and a string cutter for reciprocating the string feed guide, and the like are provided on the binding case (54). It comprises a feeding roll (9) and a sub feeding roll (10).

A string roll box (7) for accommodating a string (5) is provided on the right side of the engine unit (15), and the string (5) taken out from the string roll box (7) is connected to the binding device (6). The string (5) is put into the bale forming chamber (3) from the cord feed guide through the space between the main and sub feeding rolls (9) and (10), and is formed in the bale forming chamber (3). After the bale (A) is completed to a fixed size, the sub-feeding roll (10) becomes the main feeding roll (9).
When the string (5) is fed into the bale forming chamber (3) by pressure contact with the cord, the string (5) is wound around the rotating completed bale (A) as shown in FIG. By guide
The string (5) is wound around the outer periphery of the bale (A) while being guided, and at the same time, the string (5) is cut by a string cutter, and the side door is opened to be taken out of the bale forming chamber (3).

Next, in FIG. 1, between the string roll box (7) and the binding device (6), a string brake for loosening the string (5) is provided on the string roll box (7) side. (8) is attached, and the string (5) taken out from the string roll box (7) passes through the string brake (8) and the binding device (6).
The string brake (8) is introduced into the bail forming chamber (3) from between the main and sub feeding rollers (9) and (10). A moving piece (56) connected to one end of the moving piece (55) is opposed to the moving piece (56).
7) elastically presses the fixing piece (55) side to apply a braking force to the string (5), and the other end of the wire (5)
8) is connected to the working clutch lever (18), and the sub-feeding roll (10) opposed to the main feeding roll (9) is a swing arm having a shaft (59) as a fulcrum. -M (60)
(61) is pivotally supported at the lower end of the main feeding roll (9) so as to be pressed against or separated from the main feeding roll (9).
The upper end of (0) is connected to the working clutch lever (18) via a wire (62).

As a result, the material scattered in the field as the aircraft travels (forwards) is picked up by the pick-up fingers (14) rotating as shown in (b) of the pick-up unit (4) and picked up in (c) and (d) respectively. ), The main and sub conveyors (1) and (2) rotate to be taken into the bale forming chamber (3) and formed into a roll-shaped bale (A), and the bale (A) is formed. When the main conveyor (1) is completed to a predetermined size, the main conveyor (1) is changed to the release side as shown by the arrow (A) by the completed belt pressure, and the posture is changed by the wire (53). As a result, the pawl clutch provided on the pickup intermediate shaft (49) is disengaged, the power to the pickup section (4) is cut off, and the pickup of the material by the pickup finger (14) is stopped.

Therefore, the work clutch lever (18)
When the operation is performed in the entering direction, that is, as indicated by the arrow (e) , the operation causes the moving piece (56) of the string brake (8) to be pulled by the wire (58) in the (f) direction to the compression spring (57). At the same time, the auxiliary feeding roll (10) is pressed against the main feeding roll (9) via the wire (62) and the swinging arms (60) (61), while acting counteracting to reduce the braking force on the string (5). In this way, the string (5), which has been viewed from the bale forming chamber (3), is fed out to the state shown in FIG. 2, and the fed-out string (5) is wound around the outer periphery of the completed veil (A) as shown in FIG. When the winding is started, the string (5) is cut off at the end of the winding and taken out from the bale forming chamber (3) to the side.

In the description of this embodiment, it is assumed that the braking force of the string brake (8) is reduced and that the main feeding roll (10) of the sub feeding roll (10) in the binding device (6) is used. The operation of the work clutch lever (18) simultaneously causes the cord (5) to be extended by pressing against the cord (9), but the braking force of the cord (5) is reduced and the binding device (6) is used. ) Is not limited to that of this embodiment, but may be performed by other means.
