Description

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

``Prior art'' Patent application No. 60-9484, which has already been filed by the applicant
In some cases, the pickup section was still operating during the binding process.

[Problems to be Solved by the Invention] For this reason, not only is there a risk of injury if the worker accidentally comes into contact with the pickup section during the bundling operation, but also the pickup finger may be damaged if the machine is run in this state. There were drawbacks such as damage caused by contact with obstacles.

"Means for Solving the Problems" Therefore, the present invention includes a working speed change lever that switches the bale rotation speed of the bale forming chamber between high and low speeds, and
The vehicle is equipped with a pickup clutch that interrupts the drive of the pickup section, and the pickup clutch is disengaged in conjunction with high-speed switching of the speed change lever to interrupt the drive of the pickup section.

"Function" According to the present invention, bundling work can be performed under conditions where the bale rotation speed of the bale forming chamber is made high, or high-speed bale forming work or bale formation can be performed by directly introducing straw grass into the bale forming section. By stopping the drive of the pickup section during inspection work such as lubricating the drive elements of the pickup section, these operations can be performed safely, and there is no danger if the aircraft is operated in this state. Therefore, even if the pickup section comes into contact with an obstacle, accidents such as damage due to free rotation can be avoided, and the durability of the pickup section can be improved.

When the bail (A) is formed and the bail pressure detection switch (133) is turned on, the completion of this formation is detected by the operation of the buzzer (134) and the lamp (+35), and the latch lever (13) runs at this time. Turn off the
The crawler (2) is stopped, the work clutch lever (11) is switched from low speed work to high speed work, and the forming chamber (
18) Rotate the inner bale (A) at a higher speed than during this forming operation. Further, by the bundling operation of the lever (11), the twine (96) is started to be delivered from the delivery rolls (91) and (97), and the tip of the twine (96) is pushed out in the direction of the bale (A) by the feeding plate (11B). , the twine (9θ) is dropped onto the upper surface of the lower conveyor (16), and the twine (96) is delivered to the bale (A) side. Further, when the tip of the twine (96) is wrapped around the base (A) and pulled, the bundling clutch (88) becomes a member and the bundling by the twine (86) is started. During this bundling operation, the bundling switch is activated. (119) is turned off and the operation of the buzzer (+34) and lamp (135) is stopped. When the binding is completed, the twine (9B) is cut off by the cutter (103), the binding clutch (89) is disconnected, and the binding switch (119) is turned on again, the buzzer (134) and lamp (135) are activated again. Notify the worker that the bundling is complete. Then press the lever (1)
1) to the work interruption position (12) of the lever guide groove (125).
? ), the switch (+31) is turned off to stop the operation of the buzzer (134) and the lamp (135), and the bale is removed from the bale forming chamber (18) by opening the side door (36). (A) is taken out of the machine.

FIG. 13 shows another example of a modified structure of the drive system of the pickup section (4), in which the sleeve (71) freely rotatably supported on the sprocket shaft (70) is directly connected to the conveyor ( The drive sprocket shaft (56) of 17) is interlocked with the drive sprocket shaft (56) via pulleys (87) (74) and chino (Ha), and the drive structure is simpler than that of the structure of the previous embodiment, and the drive sprocket shaft (56) is connected to the pickup part (4). Drive can be transmitted effectively. Alternatively, the Cheno (Ha) transmission system may be replaced with a V-belt transmission system, and a belt tension pulley may be incorporated into the BkV belt transmission system to perform the same function as the pickup clutch (72) described above.

In addition, the driving force of the pickup section (4) is based on a Cheno (H).
) (fi9a) from the drive sprocket shaft (56) of the sub-forming pipe conveyor (17).
6), each conveyor (
to) (1?) can be balanced. In other words, the main shaping pipe conveyor (16) has a longer working length than the auxiliary shaping pipe conveyor (17), and the contact surface pressure against the veil (A) is also greater, and it is curved significantly and the chain guide (2B) (2?) The frictional force is also large,
Therefore, the driving load is also extremely large. On the other hand, the driving load of the cutting and shaping pipe conveyor (17) is small, and it is better to obtain the driving force from the conveyor (17) than to obtain the driving force for the pickup section (4) from the conveyor (16), which reduces the overall load. Balance can be achieved, and as a result, the strength of these drive systems can be uniformly reduced.

"Effects of the Invention" As is clear from the above embodiments, the present invention has a structure in which the straw picked up by the pickup section (4) is formed into a roll-shaped bale (A) using the bale formation Rg (tU). , a working speed change lever (11) for switching the bale rotation speed of the bale forming section (18) between high and low speeds, and a pickup clutch (72) for interrupting driving of the pickup section (4); )
When switching at high speed, the pickup clutch (7
2) and interrupts the drive of the pickup section (4), therefore, the bundling operation should be performed under conditions where the bale rotation speed is high, or straw grass should be directly fed into the bale forming section (!8). high-speed bale forming operation or bale forming section (
During inspection work such as lubricating each drive element in step 18), the drive of the pick amplifier section (4) is automatically stopped, making it possible to perform these work safely, and also to ensure that the aircraft is not traveling in this state. There is no danger even if
Even if the pick-up part (4) comes into contact with an obstacle, it rotates freely and accidents such as damage to the pick-up part (4) can be avoided and its durability can be improved.
