Abstract

An attachment to an existing sweep of a seeding device is provided for additional dispensing of fertilizer. A protection tooth on the leading face of the attachment can be placed at a desired depth of its lower, free end to selectively adjust the level at which the fertilizer is deposited.

Claims

1. A device for application of granular, gaseous or liquid material to the soil, comprising, in combination:

a) a rigid, earth penetrating, elongated body having a first end portion, a second end portion, a leading wall portion, a trailing wall portion and opposed side wall portions extending between the leading and trailing wall portions;

b) said body enclosing a conduit for said material, said conduit having an inlet port section near the first end portion of the body, and a discharge port section near the second end of the body;

c) securement means for rigidly securing the body to a farming implement, said securement means being disposed at a first securement point near the first end portion, and at a second securement point near the second end portion of said body;

d) said securement means near said first securement point including mounting means for mounting said body to a support shank of the frame of a farming implement;

e) a rigid, earth working, abrasion protective stem complementary with and rigidly secured to said body to overlap a substantial portion of said leading wall portion while extending beyond the length of the body, over said second end of the body;

f) the protective stem being secured to the body by releasable mounting means for securing the stem to the body at a selected length of extending over said second end, whereby the distance between a free end tip of the stem from the distance port section is selectively adjustable.

2. The device of claim 1, wherein said discharge port section coincides with said second end portion and is limited by said leading wall portion, said trailing wall portion and said opposed side wall portions.

3. The device of claim 1, wherein said body is of a generally rectangular cross-section and wherein the contour of sides of said protective stem generally corresponds to that of said leading wall portion.

4. The device of claim 1, wherein said body is of a generally rectangular cross-section and wherein the contour of sides of said protective stem generally corresponds to that of said leading wall portion;

and said discharge port section coincides with said second end portion and is limited by said leading wall portion, said trailing wall portion and said opposed side wall portions.

5. A farming implement comprising a frame and a plurality of arcuate support shanks, each shank carrying at its normally lower free end a cultivator sweep having a pointed nose portion and two rearwardly divergent wings each of the cultivator sweeps being provided with seed dispensing means for dispensing seeds at a subsoil level generally coincident wit the level of penetration of the soil by the wings, said implement being further provided with applicator for granular, gaseous or liquid fertilizer material, said application including:

a) a rigid earth penetrating elongated body having an upper end portion, a lower end portion, a leading wall portion, a trailing wall portion and opposed side wall portions extending between the lead and trailing wall portions;

b) said body enclosing a conduit for said material, said conduit having an inlet port section near the upper end portion of the body, and a discharge port section near the lower end of the body;

c) securement means rigidly securing the body to the shank and thus to the frame of the implement, said securement means being disposed at an upper securement point and at a lower securement point of the body, the upper securement point being near the upper end portion of the body, the lower securement point being near the lower end portion of said body;

d) said securement means at said upper securement point including mounting clamp means mounting said body to the respective support shank;

e) a rigid, earth working, abrasion protective stem complementary with and rigidly secured to said body to overlap a substantial portion of said leading wall portion while extending beyond the length of the body, below said lower end of the body;

f) wherein the protective stem is secured to the body by releasable mounting means mounting the stem to the body at a selected length of extending below said lower end, whereby the distance between the lower end of the protective stem from the discharge port section is selectively adjustable.

6. The device of claim 5, wherein said discharge port section coincides with said lower end portion of the body and is limited by said leading wall portion, said trailing wall portion and said opposed side wall portions.

7. The device of claim 5, wherein said body is of a generally rectangular cross-section and wherein the contour of sides of said protective stem generally corresponds to that of said leading wall portion, when the implement is viewed from the front.

8. A farming implement comprising a frame and a plurality of arcuate support shanks, each shank carrying at its normally lower free end a cultivator sweep having a pointed nose portion and two rearwardly divergent wings each of the cultivator sweeps being provided with seed dispensing means for dispensing seeds at a sub soil level generally coincident with the level of penetration of the soil by the wings, said implement being further provided with applicator for granular, gaseous or liquid fertilizer material, said application including:

a) a rigid earth penetrating elongated body having an upper end portion, a lower end portion, a leading wall portion, a trailing wall portion and opposed side wall portions extending between the lead and trailing wall portions;

b) said body enclosing a conduit for said material, said conduit having an inlet port section near the upper end portion of the body, and a discharge port section near the lower end of the body;

securement means rigidly securing the body to the shank and thus to the frame of the implement, said securement means being disposed at an upper securement point and at a lower securement point of the body, the upper securement point being near the upper end portion of the body, the lower securement point being near the lower end portion of said body;

d) said securement means at said upper securement point including mounting clamp means mounting said body to the respective support shank;

e) a rigid, earth working, abrasion protective stem complementary with and rigidly secured to said body to overlap a substantial portion of said leading wall portion while extending beyond the length of the body, below said lower end of the body;

f) wherein said securement means further includes an abutment seat located at said lower securement point and being generally in coincidence with the trailing wall portion of said body, said seat being complementary with and engaging the pointed tip of the respective sweep.
