Abstract

A device for planting seed and applying fertilizer including a frame adapted to be moved over the ground and a furrow opener shank carried on the frame. A first delivery tube is provided in the shank for fertilizer and has a lower end disposed to a first predetermined level below the ground. A second delivery tube for seed is also provided and has a lower end disposed at a second predetermined shallower level. The second tube is positioned behind the first tube with respect to the direction of travel. Earth tends to fill in around the fertilizer as the shank moves along. This provides an earth seed bed which separates the seed from the fertilizer. A packer wheel is attached to the frame and trails the second tube of each shank. The packer wheel compacts the ground after delivery of the material to the ground and also regulates the depth of the shank.

Claims

1. A planting apparatus comprising:

a shank assembly having a housing defining a pair of upright tubular sections, a first of said sections having an outlet at the lower end generally centered on the shank assembly and at a first predetermined depth when the shank assembly is in a working position;

a spear point having a center portion and laterally extending wing portions, the center portion opening a furrow of maximum depth;

means to provide a granular fertilizer material to said first tubular section for depositing the fertilizer in the ground generally centered on the shank and directly behind the center portion of the spear point;

a pair of tubes mounted on the housing having first ends opening into the second tubular section adjacent the lower end of the second tubular section, the first ends of said tubes being adjacent each other and the tubes diverging outwardly and downwardly from the shank assembly housing in rearward direction, second ends of said tubes being spaced apart laterally and terminating rearwardly of the housing and forming outlet ports at a level above the center portion of the spear point and deposited fertilizer and above and behind the lateral portions of the spear point, the tubes having solid walls that diverge sideways in rearward direction and which tend to divide the furrow to be wider than the housing immediately ahead of the outlet ports;

means to provide seed grain to said second tubular section; and

guide wall means for guiding the seed grain from the second tubular section into the two tubes and dividing the seed grain from said second tubular section into two portions, one of which portions is provided to one of the pair of tubes, and the other of which portions is provided to the other of the pair of tubes.

2. The planting apparatus of claim 1 wherein said housing comprises a generally rectlinear cross sectional configuration, and the first and second tubular sections are formed by a vertically extending wall dividing the housing into two chambers.

3. The planting apparatus of claim 1 wherein connection conduits are mounted on and extend to the rear of said housing above the lower end thereof, one of said connection conduits passing from the rear of the housing completely through said second tubular section to open into said first tubular section.

4. The planting apparatus of claim 1 wherein the guide wall means includes edge portions of the pair of tubes being adjacent each other at the first ends which open into the second tubular section, the edge portions of the pair of tubes at the first ends thereof forming the means to divide the material into two portions.

5. The planting apparatus of claim 1 and means to permit mounting the shank assembly to a support beam.
