Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of 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 at a baler unit, The present invention relates to a roll baler configured to be bound by twine supplied from a binding device.

"Prior Art" In Japanese Patent Application No. Sho 60-9484 (Japanese Patent Application Laid-Open No. 61-170316), which has already been filed by the present applicant, the pickup unit was driven even during the binding operation.

[Problems to be solved by the invention] Therefore, not only is there a risk that the worker may get injured if the pick-up part unexpectedly touches the pick-up part during bundling work. There was a defect such as contacting an obstacle and damaging it.

"Means for Solving the Problems" Therefore, the present invention is provided with a work speed change lever for switching the bale rotation speed of the bale forming chamber between high speed and low speed,
A pickup clutch for interrupting the drive of the pickup unit is provided, and the drive of the pickup unit is interrupted by disengaging the pickup clutch in conjunction with the high speed switching of the shift lever.

[Operation] Thus, according to the present invention, a bundling operation under the condition that the bale rotation speed of the bale forming chamber is set to a high speed, or a high-speed bale forming operation or a bale forming operation in which straw grass is directly added to the bale forming portion. For inspection work such as lubrication of the drive elements of the parts, by stopping the drive of the pickup part, it is possible to perform each of these operations safely, and even when the aircraft is running in this state, there is danger. Therefore, even if the pickup portion comes into contact with an obstacle or the like, accidents such as damage due to free rotation are avoided, and the durability of the pickup portion can be improved.

FIG. 12 shows an alarm circuit, which is turned on when the bale contact pressure of the power supply (132) and the conveyor (16) on the conveyor (16) exceeds a certain level to detect the completion of bale formation. An alarm buzzer (134) and a lamp (135) are connected via a pressure detection switch (133) and the work interruption switch (131), and the bale forming chamber (18) is driven while the pipe conveyors (16) (17) are driven. There is a bale (A) formed inside, and these buzzers (13
4) and the lamp (135) are configured to operate.

As shown in FIGS. 2 to 3, the rear end of the upper cover (3c) of the baler portion (3) is rotatably attached to the rear portion of the main body of the baler portion (3) via a hinge (136). hand,
A front end side of the cover (3c) is provided so as to be openable.

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 main shaping pipe conveyor (16), and the main and sub shaping pipe conveyor (16). ) (17) is formed into a roll-shaped bale (A). And the veil (A)
When the bail pressure detection switch (133) is turned on, the completion of the formation is detected by the operation of the buzzer (134) and the lamp (135). At this time, the traveling clutch lever (13) is turned off and the crawler is crawled. (2) is stopped, the work clutch lever (11) is switched from low speed work to high speed work, and the bale (A) in the forming chamber (18) is rotated at a higher speed than during this forming work. Further, the twine (96) is started to be fed from the feeding rolls (91) (97) by the binding operation of the lever (11), and the tip of the twine (96) is pushed out in the bale (A) direction by the feed plate (116). , Twine on top of the lower conveyor (16) (96)
Is dropped and the twine (96) is sent to the bale (A) side. Further, the tip of the twine (96) is wound around the bale (A) and pulled, and the binding clutch (89) is turned on to start binding by the twine (96). During the binding work, the binding switch (119) is used. ) Is turned off and the operations of the buzzer (134) and the lamp (135) are stopped. When the bundling is completed, the cutter (103) is used to
When 6) is disengaged and the binding clutch (89) is disengaged and the binding switch (119) is turned on again, the buzzer (134) and the lap (135) are activated again to notify the operator of the completion of the binding. After that, the lever (11) is moved to the lever guide groove (12
By returning to the work interruption position (127) of 5), the switch (131) is turned off to stop the operation of the buzzer (134) and the lamp (135), and the side door (36) is opened. Bale forming chamber (18) to bale (A)
Is taken out of the plane.

FIG. 13 shows another modified structure example of the drive system of the pickup section (4), in which the cylindrical shaft (71) which is supported by the sprocket shaft (70) as an idle shaft is directly connected to the conveyor. Pulley (67) (7) to drive sprocket shaft (56) of (17)
4) and the chain (69a) are interlockingly connected, and the drive structure can be simplified and the drive to the pickup unit (4) can be effectively transmitted as compared with the structure of the above-mentioned embodiment. Further, the chain (69a) transmission system may be replaced with a V-belt transmission system, and a belt tension pulley may be incorporated in the V-belt transmission system to perform the same operation as the pickup clutch (72) with this tension pulley.

The driving force of the pickup unit (4) is the chain (6
9) It is configured to obtain driving force from the main shaping pipe conveyor (16) by being configured to obtain from the drive sprocket shaft (56) of the sub shaping pipe conveyor (17) via a transmission system such as (69a). In comparison, each conveyor (16) (17)
Can be balanced.
In other words, the main shaping pipe conveyor (16) has a longer working length than the sub shaping pipe conveyer (17), the contact surface pressure against the bale (A) is also large, and it bends greatly, and the chain guides (26) (27) Has a large frictional force, and therefore its driving load is also significantly large. On the other hand, the driving load of the sub-shaping pipe conveyor (17) is small and the driving force of the pick-up part (4) is obtained from the conveyor (16) rather than the conveyor (17).
The more the driving force is obtained, the more the load can be balanced as a whole. As a result, the strength of these drive systems can be reduced uniformly.

[Effects of the Invention] As is clear from the above embodiments, according to the present invention, the straw bale picked up by the pickup part (4) is formed into a roll-shaped bale (A) by the bale forming part (18). The work gear shift lever (11) for switching the bail rotation speed of the bail formation portion (18) between high and low speed, and a pickup clutch (72) for interrupting the drive of the pickup portion (4). When the high speed switching of (11) is performed, the pickup clutch (72) is disengaged to interrupt the drive of the pickup section (4) in association with this, so that the bundling work under the condition that the bale rotation speed is high or For inspection work such as high-speed bale forming work by directly inserting straw grass into the bale forming part (18) or inspection work such as lubrication of each drive element of the bale forming part (18), the pickup part (4 By automatically stopping the drive of the machine, each of these operations can be performed safely, and there is no danger even when the aircraft is running in this state, and the pickup unit (4) hits obstacles, for example. Even if they come into contact with each other, the free rotation causes an accident such as damage to the pick-up part (4) and avoids an accident, which has a remarkable effect of improving durability.
