Narrow profile soil opening device for agriculture material placement
First Claim
1. An opener assembly for forming a groove in soil in preparation for placement of substances in the soil, said opener assembly comprising:
- an upright, elongated shank having a lower end and a lower mounting edge;
a lowermost, groove-forming component, said component having an upper mounting surface; and
fastening structure for fastening said component to said lower end of said shank with said upper mounting surface of said component adjacent to said lower edge of said shank,said lower edge of said shank including a pair of angularly disposed edge portions arranged to receive thrust loads in different directions from said component during groove-forming movement of said component through the soil,one of said edge portions lying at least partially in a normally horizontal plane for preventing upward movement of said component relative to said shank and the other of said edge portions lying at least partially in a normally vertical plane for preventing rearward movement of said component relative to said shank,said fastening structure permitting pivotal and translational movement of said component with respect to said horizontal plane.

Abstract
An opener assembly for forming a groove in soil in preparation for placement of substances in the soil broadly comprises an upright, elongated shank having a lower end and a lower mounting edge, a lowermost, groove-forming component, and fastening structure for fastening the component to the lower end of the shank. The component includes an upper mounting surface, and is configured to be seated against the lower mounting edge of the shank. The lower edge of the shank includes a pair of angularly disposed edge portions arranged to receive thrust loads in different directions from the component during groove-forming movement of the component through the soil. One of the edge portions lies at least partially in a normally horizontal plane for preventing upward movement of the component relative to the shank while the other of the edge portions lies at least partially in a normally vertical plane for preventing rearward movement of the component relative to the shank. The fastening structure is configured to permit pivotal and translational movement of the component with respect to the horizontal plane.

14. An agricultural attachment device for placing substances in the soil having a trash clearing device and a placement device located behind said trash clearing device, said placement device comprising:
-
an upright, elongated shank having a lower end and a lower mounting edge; a trash-cutting disc including a pair of opposed disc faces, said disc being mounted on said lower end of said shank for rotation about a transverse axis; a lowermost, groove-forming component, said component having an upper mounting surface and a forward leading edge; and fastening structure for fastening said component to said lower end of said shank adjacent to one of said faces of said trash-cutting disc with said upper surface of said component adjacent to said lower edge of said shank, said lower edge of said shank including a pair of angularly disposed edge portions arranged to receive thrust loads in different directions from said component during groove-forming movement of said component through the soil, one of said edge portions lying at least partially in a normally horizontal plane for preventing upward movement of said component relative to said shank and the other of said edge portions lying at least partially in a normally vertical plane for preventing rearward movement of said component relative to said shank, said fastening structure permitting pivotal and translational movement of said component with respect to said horizontal plane. - View Dependent Claims (15, 16, 17, 18, 19)
