Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll baler for collecting collected grass, waste straw, etc., which are cut off and left, and packing them in a roll-shaped bale. It is. 2. Description of the Related Art Such a roll baler is disclosed in
As described in Japanese Patent No. 70640, scattered objects on the ground are taken into a bale forming chamber from a pickup device via a conveyer, and a bale is formed by a bundling conveyor. [0003] In such a roll baler, in order to take in a large amount of collected material, it is necessary to widen the collected material inlet to a certain extent, and a short and easy-to-separate collecting material such as a straw can be obtained. In the case of goods, even if they are conveyed on the conveyor and taken into the bale chamber, they are pulled out of the collection intake while being rotated by the bundling conveyor, and stagnate a lot in front of this collection intake. However, at the time of binding, when supplying twine into the bale forming chamber from the collected material intake port, the stagnated collected material sometimes hinders entry into the bale forming chamber. In addition, when taking in long straw, the straw is pulled out by the folded part at the front end of the bundle conveyor, and the straw is pulled out from the bale chamber, and the straw is clogged on the upper part of the bundle conveyor. There was a problem that it took time. SUMMARY OF THE INVENTION It is an object of the present invention to provide a roll baler capable of promptly informing an operator that a large amount of collected material has stagnated in front of and above a collected material inlet, and for easily removing jammed straw. [0004] A conveyor 7 is provided between a pick-up device 5 provided below the front of the machine and a bale forming chamber 6 provided with a bundling conveyor 4 for compressing and collecting the collected material into a bale. In a roll baler that supplies and binds a bundling twine 19 into the bale forming chamber 6 from above the collected material intake 9 formed between the transport conveyor 7 and the folded portion at the front end of the bundling conveyor 4, The string case 1 attached to the upper surface 3 of the fuselage is housed in the space A above the folded portion 2 at the front end, and the other end thereof is rotatable upward with the front end or rear end of the attachment portion as a fulcrum. When the collection is stagnant in the upper space portion A near the turn-back portion 2, the string case 1 is configured to be able to retreat and rotate upward by the pressing force. The collected objects picked up from the ground by the pick-up device 5 are placed on the conveyor 7 and sent into the bale forming chamber 6 while being pressed by the object pressing member 8, where they are bundled. While being rotated at 4, the bale is compression-molded. However, since the folded portion 2 is provided at the front end of the bundle conveyor 4, the collected material may be wound up in the upper space A and stagnated. The small amount of stagnation has little effect on the supply of twine, but if the amount of stagnation is large, it is necessary to remove the clogs as soon as possible. According to the present invention, the collected matter stagnating in the space A can push up the string case 1 with the pressing force, so that the worker can be quickly notified of the stagnated collected matter. In addition, since the string case 1 in the place where the collection is stagnated is opened upward, the cleaning of that part can be performed easily. When a large amount of collected material that hinders the supply of twine stagnates, the string case 1 is opened, which is also a reference for the cleaning time. An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, a transport conveyor 7 is provided following a pickup device 6 provided below a traveling machine base 13 equipped with a traveling device 12 including a crawler 11. Fixed machine frame 14 and movable machine frame 14a mounted on traveling machine stand 13
Inside the conveyor 4 and the rear part of the conveyor 7
A cylindrical bale forming chamber 6 is provided. Above the conveyor 7, the support shaft 1 laid horizontally on the left and right sides of the fixed machine frame 14.
5 is provided with a conveyed article pressing member 8 extending from the front part of the conveyer 7 to the collected object take-in port 9 so as to press the collected object toward the conveyed conveyor 7. Fixed machine frame 14
Above the conveyor 7 in the front part of the
When the bale in the form of a roll is compression-molded in the bale forming chamber 6, the twine 19 is supplied into the bale forming chamber 6 into the bale that has been compressed into a roll in the bale forming chamber 6. The twine 19 is wrapped around the entire width. A guide plate 17 for guiding a bale rolling out of the bale forming chamber 6 to a rear portion of the traveling device 12 is provided at a lower rear portion of the fixing machine frame 14. A prime mover frame (not shown) having a prime mover mounted on the side of the stationary machine frame 14 and the movable machine frame 14a is provided on the traveling machine stand 13. Next, the working mode of the roll baler configured as described above will be described. When the driving device 12, the transport conveyor 7, the bundling conveyor 4, and the pickup device 5 are driven by the motor, the pickup device 5 picks up collected materials, such as straw and grass, and transfers the collected materials to the transport conveyor 7. The collected material transferred to the conveyor 7 is supplied into the bale forming chamber 6 from the collected material inlet 9 while being pressed by the transferred object pressing member 8. The collected material supplied to the bale forming chamber 6 is bundled in a roll state by the rear part of the transport conveyor 4 and the bundle conveyor 4, and then, the twain 19 drawn out from the twine supply device 16 is baled through the collected intake 9. It is supplied into the molding chamber 6 and wound around the bale and bound. When the binding is completed, the movable machine frame 14a is rotated upward to open the bale forming chamber 6, and the bale is rolled out of the machine. In such a roll baler, it is necessary to widen the bale forming chamber 6 to a certain extent in order to prepare for taking in a large amount of the bale formation chamber. At both ends of the bundle conveyor 4 for forming and forming a roll-shaped bale while rotating the collection, there are folded portions of the conveyor, and particularly, the front end of the bundle conveyor 4 located above the collection intake 9. Part 2
In the case of, the collected material protruding from the collected material inlet 9 may be wound up by the folded portion 2 and stagnated in the upper space A. The collection stagnation in this area has little effect on the formation of the veil,
It becomes an obstacle at the time of 9 supply. A string case 1 is provided in the space A above the folded portion 2 at the front end of the bundle conveyor 4, and as shown in FIG. The twine 19 for packing the bale is placed in the string case 1 so as to be horizontally laid.
On the upper side of the string case 1, there is provided a lid 20 rotatably attached to the upper surface 3 of the machine body with a butterfly plate 21. A fulcrum shaft 18 is provided in the vicinity of the body upper surface 3 on the front side of the string case 1, and the string case 1 is configured to rotate upward with the fulcrum shaft 18 as a fulcrum, and the rear end of the string case 1 lifts the lid 20. ing. The lid 20 can be opened at the time of replenishment or replacement of the twine 19, and when the collection stagnates below the string case 1, the string case 1 is opened upward with the lid 20 by the pressing force,
The worker can be notified of the stagnation of the collection at an early stage.
The lid 20 may be rotatably provided on the string case 1, or may be fixed to the upper surface 3 of the body, and the upper surface 3 itself may be integrally rotated. That is, any cover may be used as long as the string case 1 is rotated upward by the pressing force of the stagnated collected object and is lifted and moved. FIG. 3 illustrates removal of the string case 1.
The fulcrum shaft 18 is fitted into a U-shaped rotating member 22 of the string case 1, and after opening the lid 20, the string case 1 is rotated in the direction of arrow B about the fulcrum shaft 18 as a fulcrum. And the entire string case 1 can be removed. With the above-described configuration, when the collected material is stagnated in the space A above the front end folded portion 2 of the bundle conveyor 4, the stringing case 1 is pushed up by the pressing force to notify the worker of the stagnated collected material. In addition, since the stagnation area is opened, the collection can be easily removed. In addition,
Regarding the fulcrum shaft 18 for rotating the string case 1, the same effect is obtained not at the front end but at the rear end of the string case 1.
