Description

[Detailed Description of the Invention] (Industrial field of application) The present invention collects and collects collected waste such as straw that has been mowed and foraged or threshed and released to the ground while compressed and packed in a roll-shaped bale. About roll baler.

(Prior Art) A roll baler is provided with a pickup device for picking up a collected material from the ground below the front of a bale molding chamber that compresses the collected material into a roll shape, and a pipe shape that conveys the collected material to the bale molding chamber. A carrying-in device including a carrier is provided between the pick-up device and the bale forming chamber, and a bale forming feeding device that compresses the collected matter into a roll shape while rotating the collected substance in the bale forming chamber is provided.

For example, in the roll baler described in JP-A-61-271923, the carrying-in device is configured by a lower pipe conveyor in which pipes and straw fall prevention plates having a U-shaped cross section are alternately crossed at predetermined intervals, and the bale is provided. In the molding chamber, there is provided a bale molding feeding device constituted by an upper pipe conveyor in which round pipes are laid horizontally at a predetermined interval to impart a rotary feeding action to the collected material.

(Problems to be solved by the invention) In the above-mentioned carrying-in device, since the conveying surface on which the collected matter is placed is formed of a round pipe, it is slippery and does not sufficiently feed the collected matter, or the collected matter is in the middle of conveyance. However, there is a drawback that it easily leaks from the gap between the pipes.

For this reason, in the carry-in device described in the above publication, the straw fall prevention plate having a U-shaped cross section is laid across the arrangement interval of the pipes, but the fall prevention action is not sufficient, and The alternate arrangement of the straw grass fall prevention plate is troublesome to assemble at the time of production and may be mistakenly assembled.

(Means for Solving the Problem) Therefore, in the present invention, a conveying tool 3 for receiving an object to be conveyed from the rear portion of the pickup device 1 into the bale forming chamber 2 and a pressing force for pressing the conveying tool 3 from above. 33,34,
In a roll baler provided with a carry-in device 4 composed of 35, a conveyance assisting body 7 and a pipe in which an uneven edge 6 in which a plane portion substantially parallel to a conveyance surface is erected is formed by bending with a single plate body.
The conveying tool 3 was constructed by integrally fixing 31 with the uneven edge 6 protruding from the pipe 31.

(Effects and effects of the invention) Since the carry-in device 4 puts the collected material picked up from the ground by the pick-up device 1 on the carrying surface of the carrying tool 3 and sends it into the bale forming chamber 2 while pressing it with the pressing tools 33, 34, 35. But
Since the transport tool 3 is configured by integrally fixing the pipe 31 and the transport auxiliary body 7, the pipe 31 receives the load of the transport object while the flat portion 5 of the auxiliary body 7 collects each of the pipes 31, 31. Leakage from the gap is prevented, and the uneven edge 6 protruding most upwards gives a feeding action to the collected material, so that the collected material does not slip and become stagnant. Further, since the carry-in device 4 is configured by the carrier 3 having the same shape in which the auxiliary body 7 is fixed to the pipe 31, the assembly is not mistaken.
