Abstract
A calibration device and method for calibrating, via a handheld drill, a seed drill having a calibration shaft. The calibration device comprises a housing, an input shaft, a transmission, and an output shaft. The input shaft and output shaft extend from opposite sides of the housing. The transmission drivably connects the input shaft to the output shaft so that rotation of the input shaft results in rotation of the output shaft. The output shaft is configured to drivably engage the calibration shaft. The input shaft is configured to be actuated via the handheld drill.
Claims20
A calibration device for calibrating, via a handheld drill, a seed drill having a calibration shaft, wherein the calibration device comprises:
- a housing;
- an input shaft extending from the housing;
- a transmission at least partially within the housing, the transmission being drivably connected to the input shaft;
- and
- an output shaft extending from the housing, the output shaft being drivably connected to the transmission so that rotation of the input shaft results in rotation of the output shaft, the output shaft being configured to drivably engage the calibration shaft,
- the input shaft being configured to be actuated via the handheld drill.
A method of calibrating a seed drill having a calibration shaft, the method comprising steps of:
- drivably connecting an output shaft of a calibration device to the calibration shaft;
- drivably connecting a chuck of a handheld drill to an input shaft of the calibration device;
- and
- activating the handheld drill to turn the calibration shaft via the calibration device.
A calibration device for calibrating, via a handheld drill having a chuck, a seed drill having a calibration shaft, wherein the calibration device comprises:
- a housing;
- an input shaft extending from the housing, the input shaft including a hexagonal section for being engaged by the chuck of the handheld drill;
- a transmission at least partially within the housing, the transmission being a planetary gear system and being drivably connected to the input shaft;
- an output shaft extending from an opposite side of the housing relative to the input shaft, the output shaft being drivably connected to the transmission so that rotation of the input shaft results in rotation of the output shaft, the output shaft being configured to drivably engage the calibration shaft;
- a digital counter configured to track a turn count of the output shaft;
- an electronic display screen configured to display the turn count of the output shaft;
- a selection input for selecting display information;
- and
- a reset input for resetting the turn count.
