Description

[Detailed Description of the Invention] [Industrial application] The present invention picks up straw grass such as grass and straw scattered in a field by a pickup unit to form a roll-shaped bale in a bale forming chamber, The present invention relates to a roll baler configured to be bound by Twain supplied from a bundling device.

"Prior Art" Engage and connect the locking pin of the runner traverse chain to the engaging hole of the twine traverse runner, and temporarily stop the movement of the runner for the play allowance of the engaging hole at the left and right end of the runner. At the same time, an invention in which a brake is provided to forcibly move the runner by the engagement of the pin has already been applied by the applicant (Japanese Patent Application No.
-45490).

[Problems to be Solved by the Invention] However, in the above-mentioned means, when the runner is stopped moving, the tension of the twine causes the runner to be pulled toward the center of the binding to engage with the locking pin at the end of the left-right movement. Even if the locking pin moves during the play allowance of the engaging hole where the contact of the hole is temporarily interrupted, the tension could resist and the runner could be stopped by the brake, but the braking force of the brake always acts on the runner. Since it is necessary to set the braking force to the minimum force, there are problems that the stop at the left and right ends of the runner is likely to be uncertain and the runner support structure is difficult to simplify.

"Means for Solving the Problems" Therefore, the present invention provides a runner that guides and holds a twine so that the runner can reciprocate left and right, and the runner is wound laterally around the bale to wind the twine. The runner moving chain that moves the runner to the left and right by making contact with the engaging hole edge of is provided with a plurality of runner locking pins, and each pin continuously contacts the engaging hole edge at the left and right moving ends of the runner. It is characterized in that the runner is supported on the moving end by the contact of each pin while the twine is wound around the end of the bale.

"Operation" Therefore, the runner can be stopped at the left and right moving ends until the twines are wound up repeatedly by the continuous abutment of the locking pin. The twine winding operation by the reliable stop of the runner can be obtained, and the binding function can be improved and the runner support structure can be simplified as compared with the conventional one.

The fixed guide plate (101) supplies and guides the hay, and the rectifying action of the guide plate (101) is provided to evenly distribute the hay that is biased to the left and right of the conveyor (17).

The tip of the twine (78) is wound around the bale (A), and the twine (78) is pulled out by the rotation of the bale (A), so that the roll (73) is idly rotated at a speed higher than this driving speed. At the same time, the twine guide plate (86) is pushed up by the tension that pulls out the twine (78), and the result clutch (69) is turned on and off via the clutch arm (99) and shift fork (98) to move the twine moving chain. (65)
Is driven to move the runner (90) left and right, and the twine (78) is wound around the bale (A) left and right.

As shown in FIG. 8, when the runner (90) reaches the left and right moving ends, the eight locking pins (88) provided on the chain (65) ...
Continuously abuts on the edge of the engaging hole (89) of the runner (90), stops and holds the runner (90) at the left and right moving ends thereof, and double-winds the twine (78) at the left and right ends of the bale (A). Is configured as follows. As you can see from the above, Twain (78)
In a device that supports a runner (90) that guides and holds the runner (90) so as to reciprocate left and right, and winds the twine (78) around the outer periphery of the bale (A) by moving the runner (90) left and right, A plurality of runner locking pins (88) are provided on the runner moving chain (65) that moves the runner (90) left and right by contacting the edge of the dowel hole (89), and the left and right moving ends of the runner (90) are provided. So that each pin (88) is continuously brought into contact with the edge of the engaging hole (89), and while the twine (78) is overlappedly wound around the end of the bale (A), the contact of each pin (88). Lanna by contact (90)
Is configured to be supported at the moving end.

Further, as shown in FIG. 5, the cutter (85) is crimped to the stopper (102) by the spring (103), and when the runner (90) is moved forward, the twine (78) is brought into sliding contact with the back of the cutter (85). , This twine (78) resists the spring (103) against the cutter (8
5) is retracted, while the twine (78) is caught by the blade of the cutter (85) and cut when the runner (90) is returned.

Further, the one end of the twine guide plate (85) is attached to the side plate (3a) by the support arm (104), and the guide plate (86) is held down by the spring (105) while the guide plate (86) is held. ) Is provided with a normally closed type bundling switch (106). As shown in FIG. 10, when the bale (A) is formed, this pressure causes the upper pipe conveyor (16) to move the lower pipe conveyor (16). 17) The buzzer (108) and the lamp (109) are connected to the power supply (110) through a bail switch (107) of a normally open type that detects separation from the power supply (110) and a bail (110). When the A) is formed, the buzzer (108) and the lamp (109) are activated, and at this time, the handle (82) is operated to operate the twine (7).
8) is delivered, and when the twain (78) is wrapped around the veil (A), the buzzer (108) and lamp (109) are turned off,
When the twine (78) is wound around the veil (A) and the twine (78) is cut off, the buzzer (108) and the lamp (109) are activated again, and the door (36) is opened to open the bale (). A) is taken out.

Further, as shown in FIG. 1, a hanging plate (112) is swingably attached to the front end of the pickup guide plate (5) via a support shaft (111).
Is configured to be suspended, and the pick-up finger (35) is configured to improve the hay intake performance.

This 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 upper and lower pipe conveyors (16) ( 17) to form a roll-shaped bale (A). And now the veil (A)
When the diameter of is formed to be larger than the set constant diameter,
Due to the bale (A) pressure, the upper pipe conveyor (16)
Is pushed upward to turn on the switch (107), drive the buzzer (108) and the lamp (109), and notify the operator of the completion of the bale (A) formation.

When the traveling clutch lever (13) is turned off and the roll closing handle (82) is operated, the twine (7
8) is fed out, the tip of the twine (78) is wrapped around the bale (A) and pulled, the binding clutch (69) is turned on, and the binding by the twine (78) starts. Now, the binding case (60) ) The runner (90) located approximately in the center of
When the chain (65) is driven, as shown in the direction of the arrow (L) in FIG. 5, the roll (7) rolls around the outer periphery of the bale (A) during one round trip from the center to the right, from the right to the left, and from the left to the center.
3) Guide the twine (78) fed from (79) (9
It is wound spirally as shown in (1) to (5) of Fig. 11 via 1). When the runner (90) reaches the left and right moving ends and is folded back, as shown in Fig. 8, the chain (65) is The movement of the runner (90) is stopped while the eight locking pins (88) connected to the end contact the one edge (89a) or (89b) of the engagement hole (89), and the bail (A) ) Both ends of twain (7
It is intended to prevent the shape of the bale (A) from collapsing by making the winding of 8) multiple times.

"Effects of the Invention" As is clear from the above examples, the present invention is based on the Twain (7
