Agricultural Implement Tool for Undesired Plant Removal
Rotatable plant removal devices and methods of use are disclosed herein. An example device a tubular sleeve, a shaft extending through the tubular sleeve, a material removal tool that is positioned between a terminal end of the shaft and an end of the tubular sleeve, and a mounting member that is rotatably coupled to the shaft. The mounting member allows the material removal tool and the shaft to freely rotate as the device is propelled in a direction of travel within soil. The material removal tool and the shaft freely rotate to prevent collection of material around the device.
1 . A device, comprising:
a tubular sleeve;
a shaft extending through the tubular sleeve;
a material removal tool that is positioned between a terminal end of the shaft and an end of the tubular sleeve; and
a mounting member that is rotatably coupled to the shaft, the mounting member allowing the material removal tool and the shaft to freely rotate as the device is propelled in a direction of travel within soil, the material removal tool and the shaft freely rotate to prevent collection of material around the device.
2 . The device according to claim 1 , wherein the material removal tool is substantially flat and extends orthogonally to the shaft.
3 . The device according to claim 1 , further comprising a first securement member positioned above the tubular sleeve, the first securement member securing the tubular sleeve against the material removal tool.
4 . The device according to claim 1 , further comprising a second securement member positioned above the mounting member.
5 . The device according to claim 1 , further comprising a motor coupled with at least one of the tubular sleeve and the shaft, the motor imparting a rotation force to the tubular sleeve and/or the shaft.
6 . The device according to claim 1 , wherein the material removal tool has an outer-peripheral geometry that encourages rotation of the material removal tool as it is moved relative to the soil.
7 . The device according to claim 6 , wherein the outer-peripheral geometry has a consistent effective width regardless of orientation.
8 . The device according to claim 6 , wherein the outer-peripheral geometry is substantially triangular with each vertex having an arcuate shape.
9 . The device according to claim 6 , wherein the outer-peripheral geometry is substantially polygonal with each vertex having an arcuate shape.
10 . The device according to claim 9 , wherein areas of the outer-peripheral geometry between adjacent vertices are concave.
11 . The device according to claim 6 , wherein an outer edge of the material removal tool is at least one of serrated or beveled.
12 . The device according to claim 6 , further comprising bearings positioned between the mounting member and the tubular sleeve.
13 . A device, comprising:
a shaft;
a material removal tool that is coupled to a terminal end of the shaft, the material removal tool having a polygonal shape with arcuate vertices that encourage rotation of the material removal tool when the material removal tool contacts material while being propelled in a direction of travel; and
a mounting member rotatably coupled to the shaft, the mounting member being configured to couple with a driving implement, wherein the material removal tool and the shaft freely rotate to prevent collection of material around the shaft or the material removal tool during use.
14 . The device according to claim 13 , wherein an outer edge of the material removal tool is at least one of serrated or beveled.
15 . The device according to claim 13 , further comprising bearings positioned between the mounting member and the shaft.
16 . The device according to claim 13 , wherein an outer-peripheral geometry of the material removal tool has a consistent effective width regardless of orientation.
17 . The device according to claim 13 , further comprising a motor coupled with the shaft, the motor imparting a rotation force to the shaft to rotate the material removal tool.
18 . A device, comprising:
a sleeve having a first end and a second end;
a shaft extending at least partially through the sleeve, the shaft having a first end and a second end;
a material removal tool coupled to the first end of the shaft, the material removal tool being located between the first end of the shaft and the first end of the sleeve, the material removal tool having a serrated or beveled edge;
a first securement member coupled to the shaft and positioned above the second end of the sleeve;
a mounting member located above the first securement member, the mounting member being rotatably coupled to the shaft allowing the shaft and the material removal tool to freely rotate; and
a second securement member coupled to the shaft above the mounting member.
19 . The device according to claim 18 , further comprising a motor coupled with the shaft, the motor imparting a rotation force to the shaft to rotate the material removal tool.
20 . The device according to claim 18 , further comprising bearings positioned between the mounting member and the sleeve.
