Description

Technical Field

[0001] The utility model belongs to the technical field of baling machines, and in particular relates to a detachable needle frame for baling machines. Background Art

[0002] Balers are agricultural machines that pick up and bundle straw and forage grass such as rice straw, wheat straw, cotton stalks, corn stalks, rape stalks, peanut vines, and bean stalks. Common balers include corn straw balers, wheat straw balers, and rice straw balers.

[0003] The knotter is the core component of the baler for grass harvesting. Its main function is to tie the rope that wraps the grass bale into a firm and reliable rope knot. The rope knot is generally made by a large needle mechanism connected to the frame body. The rope needle inserts the grass bale and delivers the rope to the specific position of the knotter to complete the knotting. However, in the prior art, the needle frame used to install the large needle is mostly a whole U-shaped round tube or a welded U-shaped structure. It is inconvenient to replace and maintain the large needle, and it needs to be replaced as a whole. Utility Model Content
