Startvorrichtung für Verteilmaschinen von landwirtschaftlichen Produkten

摘要

A primer system for product distribution machines, such as an agricultural air seeder, a precision planter, a sprayer, or the like includes a tank or a bin for holding the product, a distribution system for conveying and distributing the product from the tank and a driving mechanism for driving the product from the tank into the distribution system at a certain rate. The driving mechanism can run automatically or it can be selectively operated, based on commands received from a controller. The controller may receive signals from a user interface and from sensing equipment, such as a ground speed detector, a pressure sensor, a flow meter etc. In a regular mode of operation, the controller runs the driving mechanism automatically at a rate calculated based on the signals received from the above mentioned systems. Most agricultural machines have the automated operation of the driving mechanism conditioned by the ground speed of the tractor being higher than a minimum speed. In a bypass mode of operation, the driving mechanism can be selectively operated by pressing a primer button on the user interface. The primer button triggers a bypass signal, instructing the controller to run the driving mechanism at a predetermined dispensing rate, regardless of other factors, such as the detected ground speed.
