Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present utility model, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

As shown in fig. 1 to 5, the present embodiment discloses an assembled coulter structure, comprising a main coulter 3 and a side coulter 4, wherein the main coulter comprises a main coulter bar 31 and a main coulter head 33, and the main coulter bar and the main coulter head are fixedly assembled through a fastening bolt 32; the fastening bolts may be installed in the lateral direction as shown in fig. 2 or in the bottom as shown in fig. 3.
