DESCRIPTION OF THE EMBODIMENT

[0028] Referring now to the drawings and more particularly to FIGS. 1-3, there is shown the ditch cutting and excavation spoil removal apparatus (10) of Applicant's invention attached to and pulled behind a vehicle such as tractor (100). The apparatus (10) is typically employed for cutting a furrow or ditch (140) into the ground surface (142) of a pasture or field (144) and simultaneously capturing the associated excavation spoil (146).

[0029] The apparatus (10), shown in detail in FIGS. 4-7, is comprised of a collection box (12) having a rectangular frame (14) with an open front (16), side walls (18), rear walls (20), an open top (22), an open bottom (24) and a pivotally mounted plow saddle (26). The front (28) of the frame (14) is provided with multiple hitch points (30) for attachment of the apparatus (10) to the hitch links (116) of a standard tractor hitch (118) having a hitch lift (120) provided on the tractor (100). The use of multiple hitch points (30) allows the apparatus (10) to be used with both small and large horsepower tractors. While it is thought that the frame (14) will be rectangular in shape a frame of any suitable geometric configuration such as a trapezoidal or cylindrical frame may be utilized.

[0030] The plow saddle (26), shown in detail in FIGS. 8 and 9, is pivotally mounted within the frame (14) of the collection box (12) on a transversely extending plow pivot bar (32). The pivot bar (32) allows the forward end cutting end (27) of plow saddle (26) to be retracted and extended from the bottom (24) of the collection box (12) by tilting or pivoting the plow saddle (26) upward and downward on the pivot bar (32). A V-shaped blade or plowshare (29) is mounted at the base (25) of the plow saddle (26) to facilitate excavation of the furrow (140). Attachment bolts or screws (34) may be used to removably mount the plowshare (29) to the plow saddle (26) to facilitate its replacement or maintenance. The plow saddle (26) and pivot bar (32) allow pivotal adjustment of the depth of plowshare (29) with respect to the ground surface (142) and, correspondingly, the depth of the furrow (140) being cut when the apparatus (10) is in use.

[0031] Upward and downward pivotal movement of the plow saddle (26) is controlled by plow lift (36). Preferably, plow lift (36) will be a double acting hydraulic cylinder linear actuator (37) having an extendable and retractable piston rod (38), the actuator (37) and piston rod (38) being pivotally attached between the plow saddle (26) and the frame (14) as shown in FIG. 8 and FIG. 9. Engaging the linear actuator (37) of plow lift (36) to extend and retract the piston rod (38) tilts or pivots the plow saddle about pivot bar (32) upward and downward through the open bottom of the collection box (12).

[0032] The plow lift (36) will allow for on-the-go adjustment of the depth of plowshare (29) and, correspondingly, the depth of the furrow (140) during use. The plow lift (36) will have hydraulic fluid lines (39) with standardized connectors suitable for connection with the hydraulic system provided with the tractor (100). While it is thought that the plow lift (36) will include a double acting hydraulic cylinder linear actuator (37), other types of linear actuators may also be utilized. Such other linear actuators may be mechanical actuators, electro/mechanical actuators, or pneumatic actuators.

[0033] The apparatus (10) may be provided with a depth indicator (40). In the embodiment shown in FIGS. 7, 8, and 9, the depth indicator is comprised of a vertically extending graduated rule (42) mounted on a support bar (44) at the top (22) of the frame (14) and a vertically extending L-shaped indicator rod (46) mounted on the plow saddle (26). Upward and downward movement of the plow saddle (26) about pivot bar (32) by means of the plow lift (36) will move the L-shaped indicator rod (46) upward and downward along the length of the graduated rule (42) to indicate the position or elevation of the plowshare (29) with respect to the frame (14) and the ground surface (142) of the field (144).

[0034] The frame (14) of the collection box (12) may also have a runner (33) that extends along the base (23) of each side wall (24) to facilitate sliding movement of the apparatus (10) along the ground surface (142) of the field (144). A flat scraper blade (35) that extends along the base (31) of the rear wall (26) of the frame (14) of the collection box (12) may also be provided to facilitate collection of the excavation spoil (146) and its movement into the collection box (12).

[0035] For use the ditch cutting and excavation spoil removal apparatus (10) is attached to the hitch links (116) of tractor hitch (118). The hitch lift (120) of the tractor hitch (118), typically, a single acting hydraulic cylinder actuator, is then activated to lift the collection box (12) so that it is no longer in contact with the ground surface (142). The tractor (100) with the attached apparatus (10) is then moved to a desired location on the field (144) where the ditching operation is to commence.

[0036] As shown in FIG. 3, the hitch lift (120) of the tractor hitch (118) is then deactivated to lower the collection box (12) of the apparatus (10) so that it is in contact with the ground surface (142). The plow lift (36) is then activated to tilt the pivotally mounted plow saddle (26) downward to correspondingly place the plowshare (29) at a desired position with respect to the frame (14) and the ground surface (142). The tractor (100) is then moved forward to engage the plowshare (29) with the ground surface (142) to cut the furrow or ditch (140). As the tractor (100) moves forward, the excavation spoil (146) from the newly cut ditch (140) is moved upward and outward away from the plow saddle (26) and plowshare (29) and collected within the excavation collection box.

[0037] The excavation spoil (146) may then be removed from the excavation collection box (12) of the apparatus (10) by activating the double acting cylinder (37) of the plow lift (36) to tilt or pivot the plow saddle (26) and plowshare (29) upward as shown in FIG. 8 and then dragging the apparatus (10) to a desired location. The excavation collection box (12) may then be lifted to a desired position above the ground surface (142) by activation of the tractor's hitch lift (120) as shown in FIG. 3b so that the collected excavation spoil (146) will by disbursed from the open bottom (24) of the excavation collection box (12).

[0038] The disbursed excavation spoil (146) may then be spread along the ground surface (142) as desired, as shown in FIG. 10, by moving the tractor (100) forward or rearward to push and pull the elevated excavation collection box (12) over the disbursed excavation spoil. Adjusting the elevation of the excavation collection box (12) by means of the tractor hitch lift (120) controls the amount and depth of the excavation spoil (146) as it is being spread along the ground surface.

[0039] In an alternate method of use, the apparatus (10) may also be used to scape, collect and remove previously cut excavation spoil (146) for deposit elsewhere. This is done by activating the double acting cylinder (37) of the plow lift (36) to tilt or pivot the plow saddle (26) and plowshare (29) upward as shown in FIG. 8. The tractor (100) is then used moving the apparatus (10) where it is to be used to remove previously cut excavation spoil (146). Then, by deactivating the tractor hitch (118) to lower the collection box (12) of the apparatus (10) so that it is in contact with the ground surface (142), the apparatus may be pulled across the ground surface over any previously cut excavation spoil (146) for collection, removal, and deposit elsewhere in the same manner as previously described.

[0040] It will be evident that various other changes may be made in the form, construction and arrangement of the parts and steps of the apparatus and method described herein without departing from the spirit, scope, and material advantages of the invention. It is also thought that the method and apparatus presented herein will be understood from the foregoing description and that the forms and steps described herein are intended to be merely exemplary embodiments of the invention.
