Abstract

A liquid application apparatus for applying liquid to soil during a planting operation, having: a ground-engaging component mounted to a planter row unit, the planter row unit opening a planting trench, the planter row unit depositing seeds in the planting trench, the ground-engaging component disposed at least partially within the planting trench as the planter row unit traverses the field; a first liquid injection conduit mounted to the ground-engaging component and disposed to inject liquid into a first sidewall of the planting trench, and wherein the ground-engaging component is mounted in a housing via at least one of a height adjustment arm that is pivotably mounted in the housing to allow for height adjustment of the ground-engaging component, and a spring that is pivotably mounted in the housing to allow for vertical deflection of the ground-engaging component.

First claim

The invention claimed is:

1 . A liquid application apparatus for applying liquid to soil during a planting operation, comprising:
a ground-engaging component mounted to a planter row unit, the planter row unit opening a planting trench, the planter row unit depositing seeds in the planting trench, the ground-engaging component disposed at least partially within said planting trench as the planter row unit traverses the field; a first liquid injection conduit mounted to said ground-engaging component and disposed to inject liquid into a first sidewall of said planting trench, and wherein said ground-engaging component is mounted in a housing via a height adjustment arm that is pivotably mounted at a first end of the height adjustment arm in the housing to allow for height adjustment of said ground-engaging component, and wherein the ground-engaging component is pivotally mounted to a second end of the height adjustment arm in the housing.

2 . The liquid application apparatus of claim 1 , wherein the ground engaging component is further mounted in the housing via a spring.

3 . The liquid application apparatus of claim 1 , wherein the ground engaging component is further mounted in the housing via a spring that is pivotably mounted at a first end of the spring in the housing to allow for vertical deflection of said ground-engaging component, and wherein the ground-engaging component is pivotally mounted to a second end of the spring in the housing.

4 . The agricultural device of claim 1 , wherein said ground engaging component includes a second liquid injection conduit configured to inject liquid into a second sidewall of said planting trench while said ground engaging component advances in said forward direction of travel.

5 . The agricultural device of claim 1 , wherein said ground engaging component includes a first wing disposed to open a first side trench in said first sidewall as said ground engaging component advances in said forward direction of travel, and wherein said first liquid injection conduit is disposed to inject liquid into said first side trench.

6 . The agricultural device of claim 1 , wherein said ground engaging component includes a first wing disposed to open a first side trench in said first sidewall as said ground engaging component advances in said forward direction of travel, and wherein said first liquid injection conduit is disposed to inject liquid into said first side trench; and wherein said ground engaging component includes a second wing disposed to open a second side trench in a second sidewall as said ground engaging component advances in said forward direction of travel, and wherein a second liquid injection conduit is disposed to inject liquid into said second side trench.

7 . The agricultural device of claim 1 , wherein said ground-engaging component is mounted to said planter row unit such that said ground engaging component engages a bottom of said planting trench rearward of a location in which seeds are deposited into said planting trench by said planter row unit as said planter row unit advances in said forward direction of travel.

8 . The agricultural device of claim 1 , further comprising: a seed firmer disposed forward of said ground-engaging component in said forward direction of travel.

9 . The liquid application apparatus of claim 1 , further comprising: a camera disposed to capture images of said planting trench, said camera in communication with a monitoring device disposed to display said captured images to an operator.

10 . The liquid application apparatus of claim 1 , wherein the height adjustment arm has pins that selectively engage holes in the housing to adjust height.
