Description

Detailed Description of the Invention "Industrial Application Field" The present invention picks up vines such as grass and straw scattered in a field with a pick-up section and forms them into a roll-shaped bale in a bale-forming chamber. The present invention relates to a roll baler that is bound by twines supplied from a binding device.

"Prior art" The locking pin of the runner cross-feeding re-chain is engaged and connected to the engagement hole of the runner for twine cross-feeding, and the movement of the runner is temporarily stopped by the amount of play in the engagement hole at the end of the left-right movement of the runner. In addition, an invention in which a brake is provided to forcibly move the runner by engagement of the pin has already been filed by the applicant (Japanese patent application filed in 1980).
-45490).

"Problem to be Solved by the Invention" However, in the above means, the runner engages with the locking pin at the end of the left and right movement where the runner is pulled toward the center of the bundle by the tension of the twine while the runner is stopped moving. Even if the locking pin moves during the free play of the engagement hole, where the contact between the holes is temporarily interrupted, the runner can be held still by the brake against the tension, but the braking force of the brake is constantly applied to the runner. Therefore, by setting the braking force to the minimum force, the stopping of the runner at the left and right ends tends to become uncertain, and it is difficult to simplify the runner support structure.

"Means for Solving the Problems" However, the present invention provides an apparatus for supporting a runner that guides and holds twines so as to be able to reciprocate from side to side, and wrapping the twines around the outer periphery of the bale by moving the runners from side to side. A runner moving chain for moving the runner left and right is provided with a plurality of locking pins for the runner, and each pin is configured to come into and out continuously at the end of the left and right movement of the runner.

``Function'' Therefore, the runner can be stopped at the ends of left and right movement by the continuous contact of the locking pin, and the runner can be temporarily stopped more reliably than in the past, without the need for a conventional brake mechanism. This allows for easier simplification of the runner support structure and the like by making the mechanical structure more convenient than in the past.

Further, as shown in Fig. 1, the hanging plate (1) is attached to the front end of the pickup guide plate (5) so as to be able to swing back and forth via the support shaft (111).
12) is suspended to improve the hay taking-in performance by the pick-up fingers (35).

The present embodiment is configured as described above, and the hay picked up by the pickup section (4) is carried into the bale forming chamber (18) by the lower pipe conveyor (17), and the hay is carried into the bale forming chamber (18) by the upper and lower pipe conveyors (16) ( 17) to form a roll-shaped veil (A).

Now, when the diameter of the bale (A) is larger than the predetermined diameter, the upper pipe conveyor (te) is pushed upward by the bale (A) pressure and the switch (107) is turned on. , a buzzer (108) and a lamp (109) are driven to notify the operator of the completion of veil (A) formation.

Then, the running latch lever (13) is turned off, and the roll closing handle (82) is operated to advance the twine (78), so that the tip fi of the twine (78) reaches the bail (
The binding clutch (6) is wrapped around A) and pulled.
8) is turned on and the binding by the twine (7th) starts, and the runner (90), which is now located at the approximate center of the binding case (80), is driven by the cheno (65) and starts binding by twine (7th).
As shown in the arrow (L) direction in the figure, the veil (A
) The twine (78) fed out from the rolls (73) (79) on the outer periphery is passed through the guide (91) as shown in (1) in Fig. 11.
~ (5) As shown in (5), the runner (90) wraps in a spiral shape, and when the runner (90) reaches the end of left and right movement and turns back, the eighth
As shown in the figure, the runner (90 ) and twine (78) at both ends of the veil (A).
The veil (A) is wrapped in multiple layers to prevent the formation of the veil (A) from being delayed.

“Effects of the Invention” As is clear from the above examples, the present invention
