Abstract
The plow which has a frame and at least one plowing implement connected to the frame, the plowing implement having a downwardly extending member with at least one ripping blade mounted on and extending forwardly on the downwardly extending member, and a sweep blade also mounted on the downwardly extending member rearwardly of the ripping blade, the sweep blade having wing like elements which extend upwardly and outwardly from a base in an arcuate manner. The plow provides for the simultaneous use of ripping elements and sweeping elements to perform both operations simultaneously.
Description
EARTH WORKING TOOL
FIELD OF THE INVENTION
The present invention relates to soil preparation devices more particularly, relates to a plow having a plowing implement.
BACKGROUND OF THE INVENTION
It has long been recognized in the art as desirable to be able to break and loosen the soil below the surface. The art is replete with devices which are designed to meet this goal. As farming has been practiced for a number of years, a great variety of different types of plowing implements have been proposed.
U.S. Patent 4,079,789 to Byrd et al discloses an earth working tool which has an implement wherein the tool blade is secured to the frame such that the tool blade will form a rearward angle in relation to the direction of forward movement whereby the soil tilt by the tool point will be prevented from rising to the surface.
U.S. Patent 5,215,150 discloses a sub soil plowing implement having winged sub soil plows break and lift the soil. The plows are mounted so that an upper surface of the wing of the plow may be oriented to vary degrees of incline to horizontal.
A further arrangement is shown in U.S. Patent 4,529,042 wherein a tillage tool includes a base plate or shank portion connected to the frame and the plow point bar over cap welded to the base plate.
Multi row plow assemblies are widely used with today's tractors. When the field is plowed, the earth to a predetermined depth is turned over so that the subsoil is brought to the surface. Recently, it has been customary, particularly in relatively low moisture crop cultivation operations to perform low tillage or no tillage to promote surface coverage so as to prevent wind and water soil erosion.
To perform low tillage operations, usually wide V-shaped sweep blades have been developed which sweep along a path below the soil surface at a relatively shallow depth. This ensures that the top surface of the soil is relatively undisturbed except for the passage of the supports upon which the sweeps are mounted.
Particularly after harvesting during dry soil conditions, it is necessary to periodically perform deep soil tilling with soil rippers in order to loosen the hardpan soil to increase moisture absorption. The soil ripping or fracturing operations are usually performed immediately before or during the sweep operations.
It is an object of the present invention to provide for a plow which allows simultaneous use of ripper blades and sweep blades so that both operations can be performed simultaneously on a single pass.
It is a further object of the present invention to provide a plow which is specifically designed to be used in relatively rugged terrain wherein relatively large obstacles are frequently encountered.
SUMMARY OF THE INVENTION
According to one aspect of the present invention, there is provided a plow comprising a frame, at least one plowing implement connected to the frame, the plowing implement having a downwardly extending member, at least one ripping blade mounted on and extending forwardly of the downwardly extending member, and a sweep blade mounted on the downwardly extending member rearwardly of the

BRIEF DESCRIPTION OF THE DRAWINGS
Having thus generally described the invention, reference will be made to the accompanying drawings illustrating an embodiment thereof, in which:
Figure 1 is a perspective view of one embodiment of a plow according to the present invention;
Figure 2 is a top plan view thereof;
Figure 3 is a side elevational view thereof;
Figure 4 is a view taken along the line 4-4 of Figure 2; and Figure 5 is a bottom view of a portion of one of the plowing implements.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to the drawings in greater detail and by reference characters thereto, there is illustrated in Figure 1 a plow which is generally designated by reference numeral 10.
Plow 10 includes, as one of its structural components, a tow bar 12 having, at one end thereof, a tongue portion 15 with an aperture 14 formed therein for
-4-attachment in a conventional manner to a tractor or other means for pulling the plow 10. Secured to tow bar 12, by mechanical means or welding, is a top transverse frame member 16 and a lower transverse frame member 18. A pair of reinforcing frame members 20 and 22 extend between tow bar 12 and upper transverse frame member 16. Frame side walls 24 and 26 extend between top transverse frame member 16 and lower transverse frame member 18.
Attached to the frame members are plowing implements 28 and 28'. As each of plowing implements 28 and 28' is substantially identical, reference will be made herein to plowing implement 28 only.
Plowing implement 28 has a substantially vertical downwardly extending member 30 which is secured by means of a pin 32 to frame side wall 24. Just below lower transverse frame member 18, vertical member 30 has a forwardly extending portion 34.
Located at the lower extremity of vertical member 30 is a triangularly shaped blade 36 which extends forwardly of vertical member 30. Extending outwardly from either side of triangularly shaped blade 36 is a horizontal V-blade 38. A
bracket 40 functions to connect triangularly shaped blade 36 and horizontal V-blade 38 to vertical member 30. Wear resistant material 39 may be applied to portions of vertical member 30 and blade 36.
Mounted rearwardly from vertical member 30 is a sweep blade assembly generally designated by reference numeral 42. Sweep blade assembly 42 has a triangularly shaped base 44. Sweep blade assembly 42 is symmetrical about a vertical
Attached to the frame members are plowing implements 28 and 28'. As each of plowing implements 28 and 28' is substantially identical, reference will be made herein to plowing implement 28 only.
Plowing implement 28 has a substantially vertical downwardly extending member 30 which is secured by means of a pin 32 to frame side wall 24. Just below lower transverse frame member 18, vertical member 30 has a forwardly extending portion 34.
Located at the lower extremity of vertical member 30 is a triangularly shaped blade 36 which extends forwardly of vertical member 30. Extending outwardly from either side of triangularly shaped blade 36 is a horizontal V-blade 38. A
bracket 40 functions to connect triangularly shaped blade 36 and horizontal V-blade 38 to vertical member 30. Wear resistant material 39 may be applied to portions of vertical member 30 and blade 36.
Mounted rearwardly from vertical member 30 is a sweep blade assembly generally designated by reference numeral 42. Sweep blade assembly 42 has a triangularly shaped base 44. Sweep blade assembly 42 is symmetrical about a vertical
-5-axis passing longitudinally through the middle of base 44 and thus, only one side will be described herein. As may be best seen in Figures 1 and 3, there is provided a lower side wall section 46, an intermediate side wall section 48, and a upper side wall section 50. Upper wall section 50, as may be seen in Figure 1, is of an arcuate configuration and has an upper marginal edge 51 which extends outwardly and upwardly and towards the rear thereof to have a wing line outline.
Formed on the bottom of base 44 is a downwardly extending center rib 52. A
pair of front V-blades 54 extend outwardly from the front of center rib 52 while at the rear thereof, a pair of rear V-blades 56 extend outwardly. It will be noted that rear V-blades 56 extending downwardly further than front V-blades 54.
Base 44 is provided with a removeable access plate 58 to provide access to the connection of the various plow components. Thus, as shown in Figure 4, middle side wall section 48 may be secured to a downwardly extending wall 60 from base 44 by means of a nut and bolt assembly 62. Similarly, although not shown, the other components can be secured by mechanical means such as nuts and bolts or alternatively, by means of welding or the like.
In operation, plowing implement 28 is designed such that rocks and other material may be lifted from the soil and upper side wall section 50, in conjunction with lower side wall section 46 and middle side wall section 48, will deflect the material latterly.
It will be understood that the above described embodiment is for purposes of illustration only and that changes or modifications may be made thereto without departing from the spirit or the scope of the invention.
