Abstract
A device for adjusting the distance between soil working tools such as plow bodies (5) disposed beside each other and fitted to sleeves (7) movable along a bar (3). Slewing brackets (11, 14, 15) for defining the movements of the sleeves (7) along the bar (3) are arranged articulatedly between the sleeves (7) so that the relative movement between the two outermost sleeves on the bar is a (n-1), where a is the distance of the movement between two adjacent sleeves (7) and n is the number of sleeves. A hydraulic piston-cylinder unit is arranged to provide the motion of the sleeves (7) along the bar (3).
Claims12
Soil-working apparatus, comprising:
- a frame adapted to be moved along over the soil, said frame including a bar extending widthwise of said frame;
- a plurality of soil-working tools transversally spaced from one another and arranged in a series which extends widthwise of said frame, said soil-working tools being adapted to workingly operate upon the soil as the frame is moved along over the soil;
- means adjustably mounting the soil-working tools to said bar, said mounting means including a series of respective sleeve means, each sleeve means being mounted to a respective said soil-working tool and adjustably mounted on said bar for movement along said bar transversally of said frame;
- length-adjustable means mounted between two of said sleeve means for adjustably moving said two sleeve means towards and away from one another along said bar and for maintaining a selected spacing thereof transverselly of said frame, said length-adjustable means being a pressurized fluid-operated extensible-retractable piston and cylinder arrangement having opposite ends connected to respective ones of said sleeve means;
- and
- mechanical linkage means coordinately interconnecting all of said sleeve means so that as said two sleeve means are moved towards and away from one another by adjusting said length-adjustble means, all of said sleeve means are coordinately respaced with some of said sleeve means thereby being caused to travel further than others in order to maintain generally proportions relative spacing regardless of absolute amount of spacing between said sleeve means.
