Abstract
This is a machine for forming V-ditches for the irrigation of soil. The machine consists of a central frame with a two wheel carriage and plows of subassemblies. Each plow consists of a right subassembly and a left subassembly universally connected to the right and left sides respectively of the central frame. Each plow forms an acute horizontal angle with the central frame. The acute angle is fixed by the use of chains, having one part adjacent to an end attached to the central frame and another part of the chain adjacent to the opposite end, attached to the extended end of the subassembly. Each subassembly contains concavo-convex rotatable discs mounted parallel to each other on a common axle. The discs are assembled so that the concave side of the discs penetrate the soil when the machine is moved forward by a suitable draft device.
Claims6
A machine for forming V ditches, the machine comprising:
- (a) a carriage for transporting the machine to and from a land area over which the machine may pass and upon which the V ditches may be formed,
- (b) a central frame comprising a plurality of individual members, the frame further comprising interlocking means for locking the individual members together to form the frame, the central frame being pivotally attached to the carriage,
- (c) means for raising and for lowering the carriage and the central frame, said means pivotally fastened to the central frame and to the carriage;
- the central frame being lowered as the carriage is raised and raised as the carriage is lowered,
- (d) forming means attached to the central frame for forming a V ditch, said forming means including a first forwardmost plow means for forming a V ditch of predetermined depth and width and a plurality of aligned succeeding tandem plow means for increasing by a predetermined amount the depth and width of the V ditch formed by a preceding plow means, wherein each plow means includes a pair of plows, one extending forwardly and outwardly from one side of the central frame and the other extending forwardly and outwardly from the other side of the central frame;
- and
- (e) a universal means for attaching each of said plows to the central frame.
