摘要:
System and method for controlling the downforce applied to agricultural implement (1) with row units (10), that has a lift control device (320). The system (300) has actuators (32) which are arranged to apply force to row units (10). The actuators (32) include down chambers (33) and lift chambers (35). Each row unit (10) comprises a downpressure control device (320) in fluid communication with the down chamber (33) for controlling pressure in each down chamber (33) separately. A lift pressure control device (310) is in common fluid communication with the lift chambers (35) of all actuators (32) for controlling pressure in lift chambers (35).

摘要:
La présente invention se rapporte à un dispositif d'implantation de graines dans le sol comportant un orifice d'entrée (21) par lequel arrive un flux d'air transportant des graines, un orifice de sortie (22) par lequel lesdites graines sont implantées dans le sol et un dispositif de séparation (23) desdites graines du flux d'air les transportant. Elle est remarquable en ce que le dispositif de séparation (23) comporte une grille (24) qui se situe sensiblement dans le prolongement dudit orifice d'entrée (21) du flux d'air avec les graines, de sorte qu'un maximum d'air s'échappe à travers celle-ci et que les graines soient retenues.
摘要:
A metering device (10) for controlling the flow of granular material through a conduit (12). The metering device (10) includes an electrical coil (20) operably associated with the conduit (12), a ferromagnetic latching strip (40) disposed in the magnetic field produced by the coil (20), and a pivoting gate (50) including a magnet (52) that is attracted toward and repelled from the latching strip (40) as the direction of electrical current flowing through the coil (20) is changed. A closed container (100) includes the metering device (10) secured to its bottom so that the granular material can be dispensed only through the meter. The closed container (100) is electrically connected by wires to a dispensing controller (300) located in the tractor cab. The granular material, such as insecticide, is simultaneously and equally dispensed at the desired rate to the seed furrows from all the individual planting units of the planter.
