Patent number: 7509785Abstract: The present invention is concerned with a roll-baler of a construction, in which the rotational movement of its rear chamber of the bale chamber for its opening and closing is done smoothly, while its lock mechanism is designed to be simple, so that the bale-shaping material of a short length may be fed into the bale chamber 4 through its inlet port “a”. In this type of the roll-baler, the bale chamber 4 is mounted on the machine body 1 at its position, where the inlet port “a” of the bale chamber 4 is open frontward, and the terminal end part 3a of the transporting conveyor 3 is so made as to its conveying surface forming an inclined surface “c” which is downwardly slanted, the inclined surface “c” being disposed at a position to constitute a part of the peripheral wall of the bale chamber 4, in opposition to the lower half side of the peripheral surface of the roll bale R to be formed within the bale chamber at the place where the inlet port “a” of the bale chamber 4 is present.Type: GrantFiled: July 31, 2002Date of Patent: March 31, 2009Assignees: Takakita Co. Ltd., Institute of Agricultural Machinery, Bio-oriented Technology Research Advancement InstitutionInventors: Kouichi Fukumori, Akira Muraki, Yuji Uemura, Masanobu Okumura, Nobuki Yamana, Hirokatsu Shito, Yukinori Shibuya
