Title
(EN) AGRICULTURAL BALER WITH FRAMELESS AND WELDLESS PLUNGER
(FR) PRESSE À BALLES AGRICOLE DOTÉ D'UN PISTON SANS CADRE ET SANS SOUDURE
Abstract
(EN)
A plunger (30, 150) for an agricultural baler (10) includes a plurality of plunger sections (210A, 210B, 210C) held together to form the plunger (30, 150), the plurality of plunger sections (210A, 210B, 210C) including a pair of plunger end sections (210A, 210C); and at least one roller (220A, 220B) and/or at least one sliding block attached to and extending laterally from each of the plunger end sections (210A, 210C). The plunger 10 (30) is characterized in that each of the plunger sections (210A, 210B, 210C) includes at least one tube holding portion (211A, 211B, 211C, 211D, 211E, 211F, 711, 811, 1211A, 1211B, 1511A, 1511B, 1511C, 1511D, 1511E, 1511F) including a tube opening (212A, 212B, 212C, 212D, 212E, 212F, 712, 816, 1212A, 1212B) formed therein; and a tube (231, 232, 731, 831, 1231, 1232) placed within the tube opening (212A, 212B, 212C, 15 212D, 212E, 212F, 712, 816, 1212A, 1212B) of each tube holding portion (211A, 211B, 211C, 211D, 211E, 211F, 711, 811, 1211A, 1211B, 1511A, 1511B, 1511C, 1511D, 1511E, 1511F) such that an interference fit is formed between the tube (231, 232, 731, 831, 1231, 1232) and the at least one tube holding portion (211A, 211B, 211C, 211D, 211E, 211F, 711, 811, 1211A, 1211B, 1511A, 1511B, 1511C, 1511D, 1511E, 1511F) of 20 each plunger section (210A, 210B, 210C) to hold the plunger sections (210A, 210B, 210C) together.
