Abstract
Apparatuses and techniques for subterranean placement or positioning of one or more items are provided. In one aspect, an apparatus is configured to form a hole in the ground and subsequently provide a pathway for positioning one or more items in the hole. In one form, the items that may subterraneously placed or positioned using the apparatus may include agricultural products such as seeds or delivery vehicles that include one or more fertilizers or pesticides or combinations of these materials.
Claims6
An apparatus, comprising:
- a first member including a first elongate body extending along a longitudinal axis between a proximal end and a distal end, the first elongate body including an elongate bore extending between a first opening at the proximal end and a second opening at the distal end;
- a second member positionable in the elongate bore, the second member including a second elongate body extending along a longitudinal axis between a proximal end and a distal end;
- and
- a locking arrangement including a first portion positioned on the first member proximally of the first opening and a second portion positioned on the second member;
- wherein the second member is rotatable relative to the first member about the longitudinal axis between a first position where the first and second portions are engaged and the second portion bears against the first member proximally of the first opening to prevent distal movement of the second member relative to the first member and a second position where the first and second portions are disengaged.
