发明名称 Electric adjusting apparatus for row cleaners
摘要 An electric adjusting apparatus for a row cleaner has a pair of upright posts connected by a pair of parallel linkages, an electric motor with a lead screw and a motor controller. One of the posts mounts on a fertilizing and/or planting apparatus and the row cleaner mounts on the other post. The electric motor moves the parallel linkages to move the row cleaner up and down without tilting. The motor controller controls the electric motor and displays the depth of the row cleaner.

主权项 1. An apparatus for adjusting the height of a row cleaner on a fertilizing and/or planting apparatus that is pulled by a tractor, comprising: a generally upright first post connected to said fertilizing and/or planting apparatus, a second post mounted on said row cleaner, a first parallel linkage having an elongated upper link and a spaced, elongated lower link, said upper link pivotally mounting to said first post at one end and pivotally mounting to said second post at an end opposite said first post, said lower link pivotally mounting, below said upper link, to said first post at one end and pivotally mounting to said second post at an end opposite said first post, such that said first and second posts are parallel and said upper and lower links are parallel, said lower link including a downwardly projecting flange, and a motor assembly having a motor, a lead screw and a lead screw nut, said motor connected to said first post, said lead screw projecting from said motor, and said lead screw nut threadedly engaging said lead screw and mounting on said flange, whereby rotation of said motor moves said flange and thereby adjusts the height of said row cleaner without tilting.
