Description

[Detailed Description of the Invention] [Industrial field] The present invention takes cut grass or straw into a bale forming chamber, forms a roll-shaped bale with the straw, and winds twain around the bale. Roll baler to be taken out of the machine.

"Prior Art" Conventionally, as disclosed in Japanese Utility Model Laid-Open No. 60-125844, there has been a technique of arranging front and rear bale forming chambers in parallel and shaping the bale in each bale forming chamber.

[Problems to be Solved by the Invention] In the above-mentioned conventional technology, after forming a bale in the rear bale forming chamber, forming a bale in the front bale forming chamber and taking out the front and rear bale, the bale is formed in the rear bale forming chamber. Can be formed again, but the bale forming operation must be interrupted until the veil in the pre-bale forming chamber is removed. Therefore, there is also a technique in which the distribution members are connected in parallel to the pipe conveyors forming the front and rear bale forming chambers, and straw can be supplied to the rear bale forming chamber even if there is a bale in the front bale forming chamber. A pipe conveyor was required, and there was a problem that straw was likely to fly out from the pipe conveyor connecting portion at the rear intermediate portion of the bale forming chamber.

"Means for Solving the Problems" However, according to the present invention, the front and rear bale forming chambers are provided side by side, and the distribution member for selectively feeding the straw grass from the pickup portion to either of the front and rear bale forming chambers. In the roll baler provided with, the front pipe conveyor is extended in an arc shape above or in front of the center of the front bale forming chamber. Or, the intermediate pipe conveyor is extended to the front side, the rear pipe conveyor is extended from above the central portion of the rear bale forming chamber to about half around the rear side, and the three pipe conveyors are provided above the central portion of the front and rear bale forming chambers. And the intermediate and rear pipe conveyor feed end portions are connected in parallel to the distribution member, and the pipe conveyor feed start end side and the rear pipe conveyor feed end side are bale in the front and rear bale forming chambers. It is characterized in that it is configured so as to be able to freely contact and separate with respect to.

[Operation] Therefore, the number of pipe conveyors attached can be reduced to easily simplify the structure for continuously forming the bale, and the pipe conveyor connection portion is arranged above the bale forming chamber to prevent straw grass from flying out of the portion. In addition to being able to easily perform the above, the front and rear bale forming chambers can be separated from the front and rear bale forming chambers by keeping the intermediate pipe conveyor shared by the front and rear bale forming chambers in a fixed posture. The other bale unloading work can be easily performed regardless of the above conditions, and the bale unloading work can be simplified and the work efficiency can be easily improved.

Bail discharge wire (75) is connected to the clutch arm (74), and after the lock pin (63) is disengaged from the door (61), the bail discharge clutch (72) is engaged and discharged. The rotation of the shaft (70) causes the discharge arm (69) to reciprocate, and the pushing force of the bale (48) of the pushing plate (66) opens the door (61) to discharge the bale (48) out of the machine. I am configuring.

Further, a rook arm (76) for engaging and supporting the clutch arm (74) is provided with the bail discharge clutch (72) held on, and when the discharge arm (69) returns to the return end, the discharge arm (69 ) Contacts the lock arm (76) to disengage the lock arm (76) from the clutch arm (74), disengages the bail discharge clutch (72), and reciprocates the pushing plate (66) once. I am configuring. As is clear from the above, the front and rear bale forming chambers (4) and (5) are provided side by side, and the straw grass from the pickup section (6) is alternatively provided in either of the front and rear bale forming chambers (4) and (5). In a roll baler provided with a distribution conveyor (51) which is a distribution member for feeding, a front pipe conveyor (16) is extended in an arc shape above or in front of the center of the front bale forming chamber (4) to form a front bale. An intermediate pipe conveyor (17) is extended above the center of the chamber (4) to the rear half and around the center of the rear bale forming chamber (5) and above the center of the rear bale forming chamber (5). A rear pipe conveyor (18) is extended about halfway around the rear side, and the rear pipe conveyor (18) is placed above the center of the front and rear bale forming chambers (4) and (5).
The pipe conveyors (16) (17) (18) of the book are connected to each other, the intermediate and rear pipe conveyors (17) (18) feed end portions are connected in parallel to the distribution conveyor (51), and the pipe conveyor ( 16) The front and rear bale forming chambers (4) and (5) on the feed start end side and the rear pipe conveyor (18) feed end side
The bale (48) (48) is configured so that it can be pressed in and out freely.

The present embodiment is configured as described above, and by operating the work clutch lever (14) in the state shown in FIG. 1, the straw picked up by the pickup section (6) moves the distribution conveyor (51). It is sent to the intermediate pipe conveyer (17) through and is shaped into the bale (48) in the front bale forming chamber (4) by the front and intermediate pipe conveyers (16) (17). Then, when the bale (48) pressure in the front bale forming chamber (4) exceeds the setting, the distribution conveyor (51) is switched and connected to the rear pipe conveyor (17) in conjunction with the bale pressure detection link (49). , While feeding straw grass from the pickup section (6) to the rear bale forming chamber (5) between the intermediate and rear pipe conveyors (17) (18), and detecting the bale (48) pressure of the link (49). The binding machine (60) is operated in conjunction with each other, and the twine (58) is wound around the outer periphery of the bale (48) of the front bale forming chamber (4).

Further, when the reveal (48) is bound by the twine (58), the lock pin (63) is detached from the bale takeout door (61) in conjunction with this ending operation, and the lock pin (63) is detached. Bale discharge clutch (72) in conjunction with operation
When the bale discharge shaft (70) is rotated, the push plate (66) is reciprocated once, and the door (61) is opened by the pushing force of the bale (48) to open the inside of the front bale forming chamber (4). Veil (4
8) is discharged to the outside of the machine.

Further, by shaping the bale (48) in the rear bale forming chamber (5), the distribution conveyor (51) is switched and connected to the intermediate pipe conveyor (17) in the same manner as described above, and the front bale forming chamber (4) is formed. The bales in the rear bale forming chamber (5) are fed from the door (61) by feeding the straw grass, bundling the bale (48) of the rear bale forming chamber (5), and reciprocating the extruding plate (66) once. (48) is discharged to the outside of the machine. Straw grass is alternately supplied to the front and rear bale forming chambers (4) and (5) to continuously shape the bale (48), and the front and rear bale forming chambers (4) ( After bale (48) of 5) was tied with twine (58), door (6)
1) is opened and automatically taken out of the machine.

"Effects of the Invention" As is apparent from the above-described embodiments, the present invention has the front and rear bale forming chambers (4) and (5) arranged side by side, and either of the front and rear bale forming chambers (4) and (5) can be selected. In a roll baler provided with a distribution member (51) for feeding straw from the pickup section (6), a front pipe conveyor (16) is extended in an arc shape above or in the center of the front bale forming chamber (4). The intermediate bale conveyor (17) is installed above the central part of the front bale forming chamber (4) to the rear half and around the central part of the rear bale forming chamber (5). 5)
