Abstract

A distance measuring device mounted to a planter used to plant crops. The distance measuring device has a cable extending between a first pulley and second pulley wherein the cable has at least one target. A sensor located adjacent the first pulley and connected to a controller sends a signal to the controller when the sensor detects the target. Adjacent the second pulley is an encoder that sends a second signal to the controller based upon the rotation of the second pulley such that the controller can determine the amount of distance that the planter has traveled.

Claims

1. A distance measuring device for a planter, comprising:

a cable extending between a first pulley and a second pulley and having at least one target;

a sensor adjacent the first pulley and connected to a controller that sends a signal to said controller when the sensor detects a target; and

an encoder adjacent the second pulley that sends a signal to the controller based on the rotation of the second pulley;

wherein the controller activates a planter when the controller receives a signal from the sensor.

2. The distance measuring device of claim 1 wherein the controller calculates a distance that the planter travels based on the number of rotations of the second pulley.

3. The distance measuring device of claim 1 wherein the controller de-activates the planter when the planter travels a pre-determined distance.

4. The distance measuring device of claim 1 wherein the planter has a framework and a shoe pivotably connected to a fixture.

5. The distance measuring device of claim 1 wherein the first pulley is rotatably connected to a shoe.

6. The distance measuring device of claim 5 further comprising a brush adjacent a support arm member.

7. The distance measuring device of claim 1 further comprising a third and fourth pulleys aligned with the second pulley for receiving the cable.

8. The distance measuring device of claim 1 wherein the second pulley is rotatable within a support arm member.
