[Industrial applications]
The present invention relates to a roll baler that collects collected grass, such as cut grass and threshing and left over the ground, and compresses it into a roll-shaped bale to pack it.
[0002]
[Prior art]
There are various configurations of the bale forming chamber of the roll baler. For example, a disk-shaped side wall is provided on the left and right sides, and a chain is wound around an arc-shaped rail provided on the outer periphery of the side wall. There is a roll baler which constitutes a bale forming chamber, and compresses and packs the collected material sent into the bale forming chamber into a roll-shaped bale while rotating.
[0003]
[Problems to be solved by the invention]
In the above-mentioned roll baler, when the collected material sent into the bale forming chamber is rotating, the collected material is caught between the chain and the rail, which hinders the bale forming, or the shape of the bale does not become a roll shape. There is.
[0004]
[Means for Solving the Problems]
Therefore, in the present invention, a large number of laterally suspended left and right side walls 1, 1 and right and left chains 3, 3 moving along arcuate rails 2, 2 provided along the outer periphery of the side walls 1, 1 are provided. And the left and right side walls 1 and 1 are divided into a fixed side wall 1a and a movable side wall 1b at substantially the center, and the transfer body 4 is moved upward together with the movable side wall 1b. In the roll baler in which the bale forming chamber 5 can be opened, a stepped portion is formed so that a gap A is formed between the chain 3 and the rail 2a at a connecting portion between the rail 2a on the fixed side wall 1a and the rail 2b on the movable side wall 1b. 6 were provided.
[0005]
Function and effect of the present invention
The collected material sent into the bale forming chamber 5 is rotated by the carrier 4 moving in an arc shape between the left and right side walls 1 and 1, and the amount of the collected material is increased and firmly compressed. Even if there is a collected material that enters between the rails 2 and 2 and the chains 3 and 3 during the bale forming, the collected material passes through the gap A between the chain 3 and the rail 2a during one rotation in the bale forming chamber 5. At this time, the collection is released, and the collection is drawn into the bale forming chamber 5 with the rotation.
In this way, it is possible to prevent a large amount of collected matter between the chains 3 and 3 and the rails 2 and 2 from hindering bale forming.
Further, when the bale forming chamber 5 is opened and the bale is taken out, a part of the collection sandwiched between the chain and the rail is easily detached, and the bale is easily taken out.

The carry-in device 11 receives collected material picked up from the ground by the front pickup device 10 and sends the collected material to the rear bale forming chamber 5. Sprockets 29 attached to the left and right sides of the front and rear rotation shafts 26 and 28 are provided. This is a configuration in which a pipe-shaped transport rod 31 is laid horizontally at a close interval.
Above the carry-in device 11, there are a plate body 12a attached at predetermined intervals to a support shaft 32 which is laid between the left and right side plates of the fixed machine frame 18, and a rod 12b such as a piano wire attached to the tip of the plate body 12a. A pressing member 12 is provided to press the collected material onto the carry-in device 11.
Further, in front of the loading device 11, the collection is pressed down by a piano wire 33 attached to the scattering prevention plate 32 of the pickup device 10.
[0009]
FIG. 3 shows another embodiment of the pressing member 12, in which the plate body 12a is rotatably arranged on the support shaft 32 at a constant horizontal interval, and is attached to another support shaft 34 suspended above the plate member 12a. The fixture 35 is pivotally supported, and the downwardly projecting portion 36 of the fixture 35 is in contact with the plate 12a. A rod 12b made of a piano wire is attached to the attachment 35.
A spring 37 is stretched over one end of the fixture 35 to push down the plate 12a and the rod 12b toward the lower loading device 11, and when the tip of the plate 12a is pushed upward, the fixture 35 is moved up. The rod 12b is pushed upward and the tip of the rod 12b is strongly pushed downward.
The fixed machine frame 18 is fixed on the traveling machine base 17, and the rear movable machine frame 19 is pivotally supported by an upper pivot shaft 38, and is interposed between the fixed machine frame 18 and the movable machine frame 19. When the hydraulic cylinder (not shown) is extended, the movable machine frame 19 rotates upward to open the internal bale forming chamber 5, and the bale compressed and packed in a roll shape is rolled backward.
[0010]
Inside the fixed machine frame 18 and the movable machine frame 19, there are left and right rotating shafts 39 extending above the inlet 60 on the fixed machine frame 18 side and rotating shafts 40 extending below the lower portion of the movable machine frame 19, respectively. A pipe-shaped carrier 4 is laid across the endless chains 3, 3 wound around sprockets 41, 42 attached to the side portions at a constant gap, and the lumen side of the chains 3, 3 is attached to the outer periphery of the side walls 1, 1. It moves along the arcuate rails 2 and 2 and the outer peripheral side is moved endlessly by two guide sprockets 43 and 44 and one tension sprocket 45. That is, the bale forming chamber 5 is formed as a cylindrical hollow chamber by the transport body 4 on the outer periphery of the left and right side walls 1 and 1.
The left and right side walls 1 and 1 are divided substantially at the center into a fixed side wall 1a and a movable side wall 1b, and the outer peripheral rail 2 is also divided into a fixed rail 2a and a movable rail 2b. The step portion 6 is formed by changing the diameter. Therefore, a gap A where the chain 3 rises is formed at this portion, and the collected material sandwiched between the chain 3 and the rail 2 comes off at the gap A.
[0011]
As shown in FIG. 2, a cutting blade 46 is attached to the lower part of the movable side wall 1b toward the chain 3 so as to cut off a part of the collected material entering between the chain 3 and the rail 2.
Since the tension sprocket 45 moves from the outside to the inside as the diameter of the bale in the bale forming chamber 5 increases, the bail diameter can be determined based on the position of the sprocket 45, and the collection of the collected material is performed at an appropriate position. By stopping and winding the twine around the bale, the packed bale diameter can be made arbitrary.
The outer peripheries of the fixed machine frame 18 and the movable machine frame 19 are covered with cover plates 47 and 48, respectively, so that the dust that has entered the bale forming chamber 5 together with the collected material does not scatter outside.
A twine supply device 49 is provided in front of the fixing machine frame 18 and above the carry-in device 11, and twine is supplied to the bale compressed in a roll shape in the bale forming chamber 5 and spirally wound around the outer periphery for packing.
