Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial application field" The present invention picks up grass and straw grass scattered in a field by a pickup unit and forms a roll-shaped bale in a baler unit. And a roll baler adapted to be bound by twine supplied from a binding device. "Conventional technology" Conventionally, as shown in Japanese Patent Application No. 60-111746, a technology has been developed in which twine is forcibly sent out and wound around a bale. "Problem to be Solved by the Invention" In the prior art, since a lever for feeding out the twine is specially provided, it is easy to perform an erroneous operation such as reversing an operation procedure with a work clutch lever for driving a baler portion, and a lever is provided. There are problems such as simplification of operation and improvement of safety cannot be easily achieved. Means for Solving the Problems However, the present invention includes a bale portion forming a bale, a pickup portion provided in front of the bale portion, and a binding device for winding twine around the bale, and a roll A roll bale in which a work bail is formed and a work clutch lever for intermittently controlling the driving force of the bailer is provided separately from the traveling clutch lever for controlling the traveling of the machine while winding the twine around the outer periphery. The structure is such that the twine is delivered and operated by a clutch lever, and the working clutch lever and the traveling clutch lever are arranged on both sides of the steering lever on the same operation surface. . "Operation" Therefore, since the drive of the baler unit and the delivery of the twine are performed by the lever operation, the twine delivery procedure is not mistaken, the erroneous operation of the lever is prevented, and the handle can be handled safely. Switching between bale forming operation and bundling operation by lever operation, simplification of lever operation and improvement of safety, etc. can be achieved more easily than before, and traveling with the work clutch lever on both sides of the steering lever on the same operation surface Since the clutch lever is provided, a worker located with the steering lever as a reference can operate the clutch levers by using both hands properly, which can reduce erroneous operation of each clutch lever by one-handed operation of the worker, and run and stop.

In the above, a binding device (10) is connected to the work clutch lever (11), and the work clutch lever (11) is configured to send and operate the twine (92), and the operation panel (the same operation surface). 9) The work clutch lever (11) and the traveling clutch lever (1) are sandwiched on both sides of the left and right side clutch levers (14), which are steering levers, on the upper surface.
3) is distributed. Next, as shown in FIGS. 11 to 13, a lever case (123) is fixed to the right side of the engine part (6), and the pickup elevating adjustment handle (12) is rotatably supported by the case (123). At the same time, a slider (125), which is a fine adjustment member, is screwed to the threaded portion (124) of the handle (12), and a rotation prevention / outer support (126) is fixed to the slider (125). An indicator (128), which also serves as a detent, protruding from the elongated hole (127) of the case (123) is integrally connected to the outer receiver (126). And the pickup section
The pickup case (32) of (4) includes a pickup elevating operation wire (129) connecting one end thereof, and an outer (130) of the wire (129) is fixed to the outer receiver (126), and the engine unit ( An elevating lever (133) is attached to 6) via fulcrum shafts (131) and (132) so as to swing back and forth and left and right, and the wire (129) is connected to the lever (133). Further, a guide groove (134) of the lever (133) is formed in the lever case (123), and the lever (133) is located at a raised position (135) and a lowered position (136) of the kite groove (134).
(133), and the lever (133) is pivoted back and forth to move the wire (129) forward and backward to move the pickup unit (4) to either the raised position or the lowered position, and the handle By the forward / reverse operation of (12), the slider (125) is moved in the axial direction of the handle (12), and the outer holder (126) is displaced along the threaded portion (124) of the handle (12). The outer part (126) is brought into contact with and separated from the lever (133), and the pickup part (4)
Is moved up and down to finely adjust the support height of the pickup unit (4) at the lower position of the lever (133). Note that a lever stopper (138) is fixed to the outer receiver (126), and the downward movement of the lever (133) is restricted by the stopper (138). 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 main shaping pipe conveyor (16), and the main and sub shaping pipe conveyors (16 ) (17) to form a roll-shaped veil (A). And when the molding pressure of the bale (A) exceeds the setting, the traveling clutch lever (
13), the crawler (2) is stopped, the work clutch lever (11) is switched from low-speed operation to high-speed operation, and the bale (A) in the forming chamber (18) is operated at a higher speed than during this molding operation. Rotate with. In addition, the twine (92) is fed out from the feeding rolls (87) and (93) by the binding operation of the lever (11), and the tip of the twine (92) is fed into the feeding plate.
It is extruded in the bale (A) direction by (109), the twine (92) is dropped on the upper surface of the lower conveyor (16), and the twine (92) is sent out to the bale (A) side. Further, the binding of the twine (92) is started by the binding of the binding clutch (84) by the tip of the twine (92) being wound around the veil (A) and pulled, and the binding (73) of the binding case (73) is started. ) Side is driven by the chain (80), as shown in the direction of the arrow (L) in FIG. 5, to the right side from the right side of the fuselage, to the left side from the right side, and from the left side. Tween (92) fed from rolls (87) and (93) on the outer periphery of bale (A) during one round trip to the center is spiraled as shown in (1) to (5) of FIG. 14 via guide (104). The runner (103
) Is folded back to the left and right moving end, as shown in FIG. 8, the eight locking pins (101) connected to the chain (80) are connected to one edge (102a) or (102b) of the engaging hole (102). The movement of the runner (103) is stopped while it is in contact with the bale (A), and the winding of the twine (92) at both ends of the bale (A) is multiplexed to prevent the bail (A) from being deformed. The bale (A) is formed and bound as described above, and the pickup unit (4) is raised to the road running (non-working) position by operating the lifting lever (133), and the pickup unit (4) is moved to the working position. And the height of the pickup unit (4) lowered to the working position by operating the raising / lowering adjustment handle (12) is finely adjusted. Also, by operating the work clutch lever (11), the bale portion (3) is driven at a low speed when forming the bale (A), and at the time of bale (A) binding, the bale portion (3) is driven at a high speed. The tweening (92) is sent out and operated according to 11). When the bail (3) is driven at a high speed, the pickup (4) is stopped. When the bail section (3) is driven at a high speed, the stopping operation of the pickup section (4) can be omitted. Further, the twine (92) sent out by the operation of the lever (11) has a feeding plate (109).
And is dropped on the main shaping pipe conveyor (16) near the bale (A) in front of the bale (A), and the twine (92) is sent to the right side of the fuselage near the door (36). After the beginning of the twine (92) wraps around the right side of the veil (A), the right end of the veil (A) is bound, then the left side of the bale (A) is bound, and the twine (92) is cut back to near the center. This completes the unity. `` Effects of the Invention''As is clear from the above embodiments, the present invention provides a baleer (3) forming a bale (A), a pickup part (4) mounted in front of the baleer (3), A bale (A) is provided with a binding device (10) for winding a twine (92) around the roll, and a roll-shaped veil (A) is formed, the twine (92) is wound around the outer periphery, and the machine is run.
