DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a roll baler pickup device for collecting pasture, straw and the like to form a bale.

[0002]

2. Description of the Related Art In the West, so-called roll balers are used for collecting pastures, and the collection is limited to pastures having a certain length.
In some cases, the straw discharged after being harvested by the combine is collected as a long straw, or after being cut and released shortly by a cutter. The pickup device plays an important role in collecting these various collections without fail.
For this reason, there are various techniques such as the technique described in Japanese Utility Model Publication No. 2-6756.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a roll baler pickup device which can collect even a short straw and the like after being cut and released by a cutter and which is excellent in maintenance. is there.

[0004]

Means for Solving the Problems A pick-up device 4 for picking up collected objects on the ground upward by a pick-up rod 2, 2 protruding and descending from a drum 1 and sending it to a carry-in conveyor 3 at the rear is arranged at the front of the fuselage. On the inner surface of the upper cover 6 of the cover 5 that covers the periphery of the pickup device 4, elastic guide rods 7, 7 that perform a resilient guide action on the collected objects from above are attached to the collected objects.
A configuration of a roll baler pickup device configured to rotate at least the upper surface cover 6 of the cover 5 together with the elastic guide rods 7 around the front end or the rear end thereof to open the upper portion of the pickup device 4. And Further, the roll baler pick-up device according to the first aspect of the present invention is configured so that the clutch 8 provided in the transmission path to the pick-up device 4 is interlocked and connected so as to be disengaged when the upper cover 6 rotates upward.

[0005]

The collections scattered in the field are picked up by the pick-up rods 2 and 2 coming and going from the drum 1 and sent to the carry-in conveyor 3 at the rear, where they are formed into a bale in the bale forming chamber 9. Is done. When the pick-up device 4 picks up a collection, the pick-up rods 2, 2 protruding and retracting from the drum 1, together with the pick-up action, the elastic guide rods 7, 7 attached to the upper cover 6. By the guiding action, the collected material is pressed and locked by the lifting rods 2 properly, and even the short straw can be reliably lifted up and sent to the carry-in conveyor 3 at the rear.
Further, when the pickup device 4 is clogged with a collected object or when performing maintenance work such as replacement of the pick-up rods 2, at least the upper surface cover 6 of the cover 5 covering the periphery of the pickup device 4. Is rotated upward about its front end or rear end, the elastic guide rods 7, 7 attached to the upper surface cover 6 are also rotated upward together to completely open the upper part of the pickup device 4. Maintenance work can be easily performed. According to the second aspect of the present invention.
Since the clutch 8 provided in the transmission path to the pickup device 4 is disengaged and linked when the upper cover 6 is rotated upward, the pickup device 4 is independent of the carry-in conveyor 3 and the like during this maintenance work. Can be manually rotated independently, and the operation can be easily performed. Further, when the upper cover 6 is rotated upward during maintenance work or bale work by driving the prime mover, the drive to the pickup device 4 is cut off as described above, and the operator erroneously operates. It is safe even if fingers are put into the cover 5.
