Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a roll baler which collects collected materials such as grass and excavation which are cut and left and packed in a roll-shaped bale.
[0002]
[Prior art]
As described in Japanese Utility Model Laid-Open No. 2-70640, such a roll baler takes in the ground scattered material from the pick-up device via the conveyor and forms the bale in a bundling conveyor. Like to do.
[0003]
[Problems to be solved by the invention]
In such a roll baler, it is necessary to widen the intake of collected material to some extent in preparation for collecting a large amount of collected material. Even if it is taken into the room, it is pulled out from the collection inlet while being rotated by the bundling conveyor, and it stays a lot in front of this collection inlet and bales from the collection inlet at the time of binding. When the twain is supplied into the room, the stagnation of the collected material may become an obstacle and prevent entry into the bale molding room.
In addition, even when taking a long sheet, it will be pulled to the folding end of the front end of the bundling conveyor, causing the hail to come out of the bale chamber, clogging the upper part of the bundling conveyor, and removing this clogged wrinkle. There was a problem that it took time.
An object of the present invention is to provide a roll baler that can quickly notify the operator that a large amount of collected material has stagnated in front and above the collected material intake and can easily remove clogged soot.
[0004]
[Means for Solving the Problems]
A conveying conveyor 7 is provided between the pickup device 5 provided in the lower front of the machine body and a bale forming chamber 6 including a bundling conveyor 4 for compressing and molding the collected material into a bale, and the conveying conveyor 7 and the front end of the bundling conveyor 4 are folded. In the roll baler for supplying and binding the binding tween 19 into the bale molding chamber 6 from above the collection inlet 9 formed between the two parts, the fuselage is placed in the upper space A of the folded portion 2 at the front end of the bundle conveyor 4. The string case 1 to be attached to the upper surface 3 is accommodated, and the other end can be turned upward with the front end or rear end of the attachment portion as a fulcrum, and the collected matter in the upper space A near the folded portion 2 The string case 1 is configured to be able to be retracted and rotated upward by the pressing force when the stagnation occurs.
[0005]
[Action and effect of the invention]
The collected material picked up from the ground by the pick-up device 5 is placed on the transport conveyor 7 and sent to the bale molding chamber 6 while being pressed by the transport material pressing member 8, and compressed into the bale while being rotated by the bundling conveyor 4. Although it is molded, since the folded-back portion 2 is present at the front end of the bundling conveyor 4, the collected material may be wound up in the upper space portion A and stagnate. A small amount of stagnation has little effect on the supply of twains, but if a large amount stagnates, it is necessary to remove clogging early. In the present invention, it is possible for the collected matter stagnated in the space A to push up the string case 1 by the pressing force and quickly notify the worker that the collected matter is stagnant.
Moreover, since the string case 1 in the place where the collection is stagnant is opened upward, the portion can be easily cleaned. When a large amount of collected material that hinders the supply of Twain is stagnant, the string case 1 is opened, which also serves as a reference for cleaning time.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, a conveyor 7 is provided following the pickup device 6 provided on the front lower side of a traveling machine base 13 equipped with a traveling device 12 composed of a crawler 11. A cylindrical bale forming chamber 6 including a rear portion of the transport conveyor 7 and a bundled conveyor 4 is provided inside the fixed machine frame 14 and the movable machine frame 14 a mounted on the traveling machine base 13.
Above the transport conveyor 7, a transport material pressing member 8 extending from the front portion of the transport conveyor 7 to the collected material intake 9 is provided on a support shaft 15 that is horizontally mounted on the left and right sides of the fixed machine frame 14. It is configured to cause a pressing action toward the transport conveyor 7.
A twain supply device 16 is provided at the front of the fixed machine frame 14 and above the conveyor 7, and when a roll-shaped bale is compression-molded in the bale molding chamber 6, the tween 19 is moved from the collection inlet 9 to the inside. The tween 19 is wound around the bale compressed in a roll shape in the bale molding chamber 6 over the entire width of the bale and packed.
A guide plate 17 for guiding the bale rolling out of the bale molding chamber 6 to the rear part of the traveling device 12 is provided at the lower rear portion of the fixed machine frame 14. On the traveling machine base 13, a motor frame (not shown) in which a motor is mounted on the sides of the fixed machine frame 14 and the movable machine frame 14 a is provided.
[0007]
Next, the working mode of the roll baler configured as described above will be described. When the traveling device 12, the transport conveyor 7, the bundle conveyor 4, and the pickup device 5 are driven by the prime mover, the pickup device 5 picks up collected materials such as straw grass and pasture and transfers them to the transport conveyor 7. The collected material transferred to the conveyor 7 is supplied into the bale molding chamber 6 from the collected material inlet 9 while being pressed by the conveyed product pressing member 8. The collected material supplied to the bale forming chamber 6 is bundled in a roll state by the rear portion of the conveyor 4 and the bundling conveyor 4, and then the tween 19 drawn from the twain supply device 16 is bale from the collected material intake 9. It is supplied into the molding chamber 6 and wound around the bale outer periphery and bound. When the binding is completed, the movable machine frame 14a is rotated upward to open the bale molding chamber 6, and the bale rolls out of the machine.
[0008]
In such a roll baler, it is necessary to widen the collection inlet 9 which is the inlet of the bale molding chamber 6 to some extent in preparation for collecting a large amount of collection. The bundling conveyor 4 that forms a roll-shaped bale while rotating the collected product has folded portions of the conveyor, and particularly at the front end folded portion 2 of the bundling conveyor 4 positioned above the collected material intake port 9. In some cases, the collected material drawn out from the collected material inlet 9 is rolled up by the folded portion 2 and stagnated in the upper space portion A. Although the collection stagnation in this portion has little influence on the forming of the bale, it becomes an obstacle when the tween 19 is supplied.
[0009]
The upper space A of the folded portion 2 at the front end of the bundling conveyor 4 is provided with a string case 1, and the string case 1 has a shape in which most of the string case 1 is stored inward from the upper surface 3 of the machine body in the left-right direction as shown in FIG. A twine 19 is provided in a string case 1 for packing a bale. On the upper side of the string case 1, a lid 20 is provided on the upper surface 3 of the machine body so as to be rotatably attached by a butterfly plate 21.
A fulcrum shaft 18 is provided in the vicinity of the upper body surface 3 on the front side of the lace case 1, and the lace case 1 rotates upward with the fulcrum shaft 18 as a fulcrum, and the rear end of the lace case 1 lifts the lid 20. ing. The lid 20 can be opened when the tween 19 is replenished or replaced. When the collected material stagnate below the lace case 1, the lace case 1 is opened upward together with the lid 20 by the pressing force, and the collected stagnation occurs. Can be notified to the operator at an early stage. The lid 20 may be rotatably provided to the string case 1 or may be fixed to the machine body upper surface 3 so that the machine body upper surface 3 itself rotates integrally. That is, any cover may be used as long as the string case 1 is rotated upward by the pressing force of the stagnant collected material and is lifted and moved.
FIG. 3 shows the removal of the string case 1, and the fulcrum shaft 18 is fitted into the U-shaped rotating member 22 of the string case 1, and after the lid 20 is opened, the string case 1. When the fulcrum shaft 18 is rotated in the direction of arrow B with the fulcrum shaft 18 as a fulcrum, the entire cord case 1 can be removed.
[0010]
With the above configuration, when the collected material stagnates in the upper space A of the front end folding portion 2 of the bundle conveyor 4, the string case 1 is pushed up by the pressing force, and the operator can be notified of the stagnation of the collected material. Because the stagnation area is opened, it is easy to remove the collected material. Note that the fulcrum shaft 18 for turning the string case 1 has the same effect at the rear end instead of the front end of the string case 1.
