INVENTOR Herbert Barros RMN@ United States Patent Ciice 3,132,430 Patented May 12, '1964 3,132,430 QUARTER DRAIN DITCHERS Herbert Barras, Box 327, Baldwin, La. Filed Apr. 11, 1963, Ser. No. 272,284 4 Claims. (Cl. 37-92) The present invention relates to quarter drain ditchers, and has for an object to provide an improved construction over my prior Patents No. 2,615,263, granted October 28, 1952, and No. 2,737,734, granted March 13, 1956.

Another object of the present invention is to provide a quarter drain cutter which will initially loosen the earth along the line of the ditch and permit the earth thus loosened to be dropped into a throwing pocket where a at throwing blade will distribute the earth in a path normal to the ditch line and in a manner as to not clog or plug the eye of the troughs between adjacent sugar cane growing rows.

A further object of my present invention is -to provide novel forms of cutting blades and to primarily provide two sets of blades in cooperative relationship with one another whereby the primary blades perform the function of loosening the earth and the secondary blades perform the scattering function and both are mounted on a common rotating member requiring a single power source.

A still further object of the present invention is to provide earth deiiecting shields circumferentially about the path of rotation of the earth throwing blades in such a manner as to regulate the angle of loft and throwing of the dirt deposited from the primary blades into the path of the earth throwing secondary blades.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.

In the drawings, wherein like symbols refer to like or corresponding parts throughout the several views: i

FIGURE l shows a sugar cane field across which has been cut a drainage ditch in accordance with prior art apparatus.

FIGURE la is a vertical section taken on the line 11-1a in FIGURE l. y

FIGURE 2 is a View similar to FIGURE l of a drainage ditch cut across a sugar cane eld with the apparatus and method of the present invention.

FIGURE 2a is a view taken on the line Zaa in FIG- URE 2.

FIGURE 3 is a side elevational view of the ditching mechanism of the present invention.

FIGURE 4 is a perspective view of the ditching mechanism of FIGURE 3.

FIGURE 5 is a rear elevational view of the ditch cutting device of the present invention shown applied to a tractor.

FIGURE 6 is a perspective view of a modified form of the present invention.

Referring for the moment to FIGURE l, a sugar cane eld is shown having hills 10 in which the cane is grown and lying therebetween are troughs 11. In order to drain the troughs 11 a quarter drain ditch 12 is cut transversely across the sugar cane field between main drainage ditches or canals (not shown) and as has been customary with prior art apparatus, as best seen in FIGURE 1, when the drainage ditch is cut the eyes vof the troughs 11 which connect with the drainage ditch 12 are plugged by deposits of earth 13 which have been thrown by the ditching machine and which deposits of earth 13 block the normal drainage of the troughs 11 to the drainage ditch v12. This necessitates going out and manually opening these eyes with a shovel which of course increases the cost of the ditching operation since this hand labor must be paidl and must be available.

Referring now to FIGURE 2, which is a view similar to FIGURE 1 in which the cane field is shown to comprise hills 10, troughs 11 and a drainage ditch 12. It will be noted that the eye area where the trough 11 meets the drainage ditch 12 s not plugged or clogged and will readily permit the water to leave the trough 11 and enter the drainage ditch 12. The deposit of earth 13 rather than be built across the eye of the ditch and trough in a damlike manner is distributed up the trough so as to afford minimum resistance to the drainage of water.

The ditch 12 shown in FIGURE 2 has been cut by first engaging the duce the compaction of the earth and to stir it up into a more granular-like mass and to drop it back to scattering blades which scattering blades hurl the dirtV at right angles to the axis of the drainage ditch and which blades cooperate wtih earth deflecting shields about the blades which cause the earth to be lofted and thrown an appreciable distance up the trough so that the earth will not form a dam at the eye of the drainage ditch and trough.

Referring now to FIGURE 5, 14 denotes a tractor having a power take-off shaft 15 at the rear thereof, which power take-oit shaft drives a sprocket and chain drive 16 for rotating a rotary driven power shaft 17; and as best seen in FIGURE 3 the power shaft 17 has secured at the front thereof for rotation therewith a pair of primary earth engaging blades 18a and 18h. Positioned rearwardly of the primary earth engaging blades v18a and 18b are two secondary earth distributing blades 19a and 19h. These secondary earth distributing blades 19a and 19b have flat faces and are mounted on and upstand from a rotary disc 20, which disc is secured to and rotates with the rotary shaft 17. As best seen in FIGURES 3, 4. and 6 the primary

earth engaging blades

18a, 18b and '33a and 33b are pitched to not only engage the earth todislodge the dirt but to impart a positive high velocity of travel to the dirt-rearwardly in an axial direction relative to the axis of rotation of the blades so that the earth strikes the disc 20 and is immediately scattered at right angle t0 the axis of rotation of the disc and primary blades by the secondary blades 19a and 19h to avoid the earth falling by gravity and slipping off the secondary blades to plug the eyes' of the troughs in communication with the quarter drain being dug.

The

primary blades

18a, 18h, 33a and'33b are angularly offset relative to the distributing blades 19a, 19h at substantially a right angle and the transverse width of the primary blades is substantially less than the arc between adjacent earth distributing blades carried by the disc whereby the primary blades engage the earth in advance of the secondary distributing blades. I

The secondary earth throwing blades 19a and 19bcarry their own tip blades 21a, 21h, which tip blades have leading edges 22a and 22h which are bent at right angles to the blade portion 21EL and are also at right angles to the rotary disc 20.

Each of the

tip blades

21a and 21b is secured to thedisc 20 by means of a bracket generally indicated at 40 which comprises two substantially

parallel sideplates

41 and 42 secured at their inner ends to the trailing face 43 of each of the blades 19a and 19h as by welding or the like. A cross brace 44 is secured to theinner faces of the

plates

41 and 42 adjacent the outer ends thereof as by welding or the like. The plate 41 is attachedrto the discl 20 by fastening elements 44a which may be bolts passingthrougih suitable openings in the plate 41 and the disc'2t). Each tip blade is secured to the plate 42 of its bracket 40 by screws 45 or the like which extend through appropriate aligned holes in the plate 42 and the tip blade.k

The leading edges 22a and 22b of the 'tip blades 21a and 21D extend radially beyond the length of the earth earth with earth loosening blades to rethrowing blades 19a and ign; and as best seen in FIG- URE 3, extend beyond earth detlecting shields 23a and 23, there being defined between 232L and 23b an opening through which earth being centrifugally hurled by blades 19a and 19b will exit. The regulation of this opening will determine the loft of the earth hurled by the blades 19a and 19b and the shields 24 will protect the tractor operator and tractor from any fortuitous flying of earth being hurled by the secondary earth throwing blades 19EL and 19h.

The shield 232L is adjustably mounted on the disc housing 26 by fastening elements 46 which extend through suitable openings in the shield 23a and are selectively received by openings 47 formed in the housing 26.

The deliecting shield 23b is adjustably mounted on the housing 26 by fastening elements 48 which extend through openings in the shield 23b and are selectively received by the openings 47 in the housing 26. The

shields

23a and 23b can therefore be circumferentially adjusted around the disc housing 26 so that the loft of the earth hurled by the blades 19a and 19b can be controlled and the location and size of the opening between the

shields

23a and 23b can be varied.

The angle of attack of the primary and secondary blades may be regulated by a sled member 25 which is pivoted to the rotary disc housing 26 as by pivots 27 and the angle of which may be regulated by a lever 28 having varying openings 29 therethrough through which passes a bolt 30 secured to a fixed part of the ditching cutter power transmission housing 31. A similar pivotal bolt 32 joins the lever 28 to the sled member 25.

Referring now to FIGURE 4 the primary earth engaging blade 18et and 18b have two substantially flat portions 18e and 18, the cutting beveled edges of which are upturned at 18c and 18d. The cutting beveled edges of the primary blades are also tapered toward their truncated ends to provide a slip off of any sugar cane or rooty matter which would tend to wrap itself about the blades.

The units shown in FIGURES 4 and 6 rotate counterclockwise so that the taper angle of the primary blades will tend to throw off material which would normally tend to wrap itself about the blades.

As shown in FIGURE 6 the primary earth engaging blades are modified from those shown in FIGURE and are designated as 32ab and 331 which are bent rearwardly toward the earth throwing blades. While the primary blades 338L and 33b of FIGURE 6 are operative, I have found that I get increased wear and longer life and a better loosening action from the form of

blade

18a and 18b shown in FIGURE 4.

Although I have disclosed herein invention known to me at this time, all such modifications and changes the scope of the following claims.
