Abstract
An improved seed planting roller for planting seeds in individual holes in the ground, and having means for reclosing the hole over the planted seed. Also, means are shown for altering the circumference of the roller for adjustment of planted seed spacing.
Claims21
In a seed-planting device having a roller member positioned for rolling contact with the ground;
- protrusions carried on the periphery of said roller member for producing holes in the ground and thereafter withdrawing therefrom while rolling;
- and means for depositing seed and the like into said holes through said protrusions;
- the improvement comprising, in combination:
- said protrusions being carried on peripherally-mounted bracket plate members;
- radially mounted, adjustable spokes secured to said bracket plate members at the ends thereof;
- means for varying the extension of said spokes to pre-set said roller member circumference prior to use, while holding the extension of said spokes and said circumference constant during use;
- and sliding linking means connecting said bracket plate members, whereby said bracket plate members and protrusions may be uniformly moved radially inwardly and outwardly by adjustment of said spokes to adjust the peripheral distance between said protrusions, said sliding linking means including wall members extending inwardly from said roller periphery, said wall members being carried by said peripherally-mounted bracket plate members, the wall members of said plate members overlapping adjacent wall members of adjacent bracket plate members, and defining generally circumferentially directed slots, and a pin member carried by each said plate member and slideable in the slot of each said overlapping wall member to slidingly connect adjacent bracket plate members, whereby the radially inward and outward movement of said connected bracket plate members is uniform.

- protrusions carried on the periphery of said roller member for producing holes in the ground and thereafter withdrawing therefrom while rolling;
- and means for depositing seed and the like into said holes through said protrusions;
- the improvement comprising, in combination:
- said protrusions being carried on peripherally mounted bracket plates;
- radially mounted adjustable spokes secured to said bracket plates at the ends thereof;
- means for varying the extension of said spokes to preset said roller member circumference prior to use, while holding the extension of said spokes and said circumference constant during use;
- and said depositing means including a plurality of tubular seed conduit shaft members each including a plurality of sections connected together in telescoping relationship, each seed conduit communicating with a protrusion.

In a seed-planting device having a roller member positioned for rolling contact with the ground, protrusions carried on the periphery of said roller for producing holes in the ground and then for thereafter withdrawing therefrom while rolling, and means for depositing seed and the like into said holes;
- the improvement comprising, in combination:
- additional shovel means, carried on the periphery of said roller, for entering the ground adjacent said holes while rolling and for dislodging dirt into said holes, to cover seeds and the like deposited therein, said protrusions each defining a forward wall facing the direction of rotation of said roller member, and an aperture facing away from said direction of rotation;
- a closure member positioned adjacent said periphery in pivoting relationship thereto, to close said aperture in a first pivoting position, and to open said aperture in a second pivoting position;
- means for biasing said closure member into said first pivoting position;
- and a foot member, movable with said closure member between said first and second pivoting positions, rigidly attached at one end to said closure member and positioned essentially tangentially of the periphery of said roller member in said first position, the other end of said foot member being spaced from said periphery in said first position, whereby contact of said foot member with the ground causes said closure member, impelled by said foot member, and said foot member, to assume said second, open position, and release from said ground contact permits said closure member and foot member to return to said first position, said foot member being positioned to sweep across said shovel means to dislodge dirt if present, while moving from said second position to said first position.
