摘要：
The drill has injection cables (17, 18) in which a funnel-shaped or Y-shaped input region (19) and an open line section (21) are formed. The region and the section are attached to two adjacent perforation lines (4) in such a manner that the region and the section support a seed peening tool, where the tool detatachably isolates the two adjacent perforation lines from perforations (5). The funnel-shaped or Y-shaped input region and the section transfer the tool into respective and/or common injection lines.
