Articulated barrier insertion attachment

Abstract

An erosion fence installation attachment for ditchers and trenchers that is short in length and articulated to pivot in pitch and yaw so as to permit the attachment to follow a ditcher through gullies over mounds and around arcs. The attachment is provided with a barrier material roll unwind, a resilient guide that guides the barrier material into a ditch formed by the ditcher so that the barrier material is pressed against the sides and bottom of the ditch to form an open channel, a first ditch fill disk that pushes fill material into the ditch and into the channel formed in the barrier material, a second ditch fill disk that pushes fill material from the opposite side of the ditch and onto and over the barrier material on that side of the ditch to form a wrap around the fill material deposited by the first fill disk so as to form an elongate anchoring pouch filled with fill material along the bottom of the ditch. A stake driven along one side the above ground portion of the barrier material will penetrate at least two layers of the barrier material further securing the anchor in place. To form a barrier fence, the barrier material is secured to the stake by conventional means.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to barrier fences used to control erosion at construction sites and the like.

More specifically, this invention relates to an apparatus for inserting and anchoring barrier fences.

Still more specifically, this invention relates the apparatus described above wherein the apparatus is in the form of an articulated attachment to a ditcher.

Construction sites and other erosion prone areas of landscape are prime candidates for the insertion of an erosion barrier. Historically, rocks, hay bales, and rooted plants and shrubs have served as erosion barriers. The development of low cost, reinforced, foramanous, plastic film, has made it the material of choice at construction sites where soil is laid bare and where even a benign water course can be severely eroded in a heavy rain.

The foraminous plastic film has numerous small openings through which water can pass, but only slowly. It is in this way that erosion barriers slow the speed of flowing water and thereby greatly reduce erosion.

The installation of a barrier fence typically involves the burying of one long edge of the barrier material in a trench that is transverse to the water course and staking the above ground portion of the barrier material to hold it upright so as to form a barrier to water flow in the water course.

2. Description of Related Art

Erosion barriers having one edge buried in the ground have a number of deficiencies that are cured by the apparatus and methods of this invention.

One vexatious deficiency of barrier fences in use heretofore, is that of pulling out of the ground or falling over when a heavy water load is backed up by the barrier. This problem has its origins in the flow characteristics of wet soil as it takes up water and develops the consistency of mud.

A vexatious problem associated with the installation of barrier fences in use heretofore is that of requiring numerous machines, and/or, machine attachments, and/or significant manual labor to install the barrier fence. Erosion barriers of the type contemplated by this invention can be installed by manual means. The functions of digging a trench, unwinding the barrier material, inserting the barrier material in the trench, filling in the trench and staking the barrier in place are all operations that can and sometimes are performed by hand. The prior art abounds in machines and apparatus that perform the tasks of trenching, unwinding barrier material, positioning barrier material, filling trenches, and staking barriers. None of these prior art devices, alone or in combination can achieve the erosion barrier installation achieved by this invention.

Yet another problem with prior art machines and apparatus for installing erosion barriers is that of length and inflexibility. Erosion barriers typically span a ditch or other undulating contours. Often it is desirable to install an erosion barrier in an arc. The inability of prior art barrier fence installing apparatus to follow contours and/or to follow curvatures due to their length and inflexibility limits the utility of the apparatus.

It is an object of this invention to provide an articulated attachment to a ditcher that can follow the ditcher through undulations and around curves while inserting erosion barrier material in the ditch formed by the ditcher, and anchoring the barrier material while filling the ditch.

It is further an object of this invention to provide the articulated ditcher attachment described above wherein the attachment performs the functions of unwinding erosion barrier material, guiding the material into a trench formed by the ditcher, forming the material into conformance with the bottom and sides of the trench, Partially filling in the trench with filling soil deposited in the barrier material lining the trench, completing the filling of the trench so that the underground portion of the barrier material wraps the soil in the barrier lining the bottom of the treanch.

It is further an object of this invention to provide the attachment described above wherein the underground configuration of the barrier material is such that a stake driven along one side of the above ground portion of the barrier will penetrate at least one layer of the underground portion of the barrier.

It is further an object of this invention to provide the attachment described above wherein the attachment is short in length and easily attached to a ditcher.

Other objects will be made apparent by the following specifications, drawings and claims.

DETAILED DESCRIPTION OF THE INVENTION

In the drawings, like numbers refer to like objects and the proportions of some elements have been modified to facilitate illustration. FIGS. 1-7 are schematic in that noncritical detail has been omitted for the sake of clarity of disclosure.

The erosion fence installation attachment of this invention is to be attached to a part of a ditcher frame that is sturdy. Ditchers typically have a sturdy frame and the attachment of a pivot pin by welding or bolting or the like is readily accomplished. In FIG. 2 , pivot pin 2 is shown attached to ditcher frame 3 of ditcher 4 .

As shown in FIGS. 1 and 2 , erosion fence installation attachment 1 comprises an insertion frame 6 having depending therefrom a barrier material unwind 8 , an insertion guide means 5 , a first ditch fill disk 22 and a second ditch fill disk 23 .

Insertion frame 6 is pivotably joined to ditcher frame 3 by means of sleeve 7 being placed over pin 2 and secured in place thereon. The pivot formed by sleeve 7 rotating on pin 2 permits attachment 1 to move in yaw mode so that attachment 1 can follow ditcher 4 around turns. Insertion frame 6 has secured thereto barrier roll unwind 8 which positions barrier material roll 9 horizontally transverse to the operating line of ditcher 4 so that barrier material 10 (shown in dashed lines in FIG. 2 ) is positioned over ditch 11 so as to create a short edge 12 and a long edge 13 relative to ditch 11 .

Insertion frame 6 is pivotably joined to sleeve 7 by means of transverse horizontal pivot 14 that permits insertion frame 6 to pivot in pitch so as to enable insertion frame 6 to follow ditcher 4 over hills and through gullies. Insertion frame 6 is provided with a resilient downward biasing means 15 , hereshown schematically as a coil spring, for the purpose of maintaining the barrier material insertion attachment 1 in contact with ditch 11 .

The articulation of ditcher 4 with insertion frame 6 by means of pivot pin 2 and sleeve 7 and the articulation of insertion frame 6 with sleeve 7 by means of horizontal pivot 14 provides the art with a short length articulated erosion fence inserter means capable of following a ditcher around curves and through gullies.

Insertion frame 6 has depending therefrom an insertion guide means 5 having a ditch bottom following shoe 21 , a first ditch fill disk 22 , and a second ditch fill disk 23 .

As detailed in FIG. 3 , ditcher 4 deposits material on both sides of ditch 11 The material becomes fill material 24 when closing ditch 11 with barrier material 10 positioned therein.

As detailed in FIG. 4 , insertion guide means 5 depends from insertion frame 6 and projects into and along the sides of ditch 11 so that barrier material 10 when passing along insertion guide means 5 is pressed against the sides and along the bottom of ditch 11 . Also, as shown in FIG. 4 , the positioning of barrier material roll 9 relative to ditch 11 causes the short edge 12 of barrier material 10 to be positioned along the side of ditch 11 and below the top edge of ditch 11 while the long edge 13 of barrier material 10 passes beside insertion guide means 5 to form what will be the above ground portion of an erosion fence. Insertion guide means 5 is configured so as to maintain long edge 13 of barrier material 10 from falling over ditch 11 and possibly interfering with the filling of ditch 11 .

Also, as shown in FIGS. 2 and 4 , bottom following shoe 21 rests on barrier material 10 and presses it against the bottom of ditch 11 as barrier material 10 passes along guide means 5 creating a channel that lines the bottom of ditch 11 .

As illustrated in FIG. 5 , first ditch fill disk 22 serves to push fill material 24 from the side of ditch 11 into the channel in barrier material 10 formed in the bottom of ditch 11 thereby partially filling the channel formed in barrier material 10 with fill material 24 .

As illustrated in FIG. 6 , second fill disk 23 closely follows fill disk 22 and serves to push fill material 24 onto barrier material 10 and into ditch 11 so as to cause fill material 24 to flow over barrier material 10 and on top of the fill material 24 deposited by fill disk 22 to create a wrap around the fill material 24 deposited by fill disk 22 creating an anchoring pouch 26 which serves to anchor barrier material 10 in the ground and renders it more difficult to dislodge than prior art erosion fences formed of barrier material 10 .

As illustrated in FIG. 7 , the completion of erosion fence 30 is achieved by driving support stakes 31 through the portion of barrier material 10 that forms anchoring pouch 26 and securing barrier material 10 to stake 31 by conventional means. The driving of stakes 31 through two of the layers of barrier material 10 that forms anchoring pouch 26 ensures that anchoring pouch 26 will not unwrap and thereby provides an anchor for erosion fence 31 that is more secure than has been heretofore obtainable.

The use of fill disks 22 and 23 in place of the more conventional blades to push fill material 24 into ditch 11 serves to permit the filling means to roll over impediments such as stones and roots and not get caught up on them as has been the case with blades and the like used to push fill material into trenches in the prior art.

The close coupling of the functions of attachment 1 permits the insertion of barrier material 10 into trench 11 over a short distance and when combined with the articulations of attachment 1 and the resilient biasing of the members of attachment 1 enables the insertion of barrier material 10 into trenches 11 that turn more sharply and span deeper ditches than has heretofore been achievable by prior art apparatus.

The above disclosures are enabling and would permit one skilled in the art to make and use the disclosed invention without undue experimentation. However, it should be understood that the scope of the invention is not limited to the scope of the disclosed embodiments, but should only be limited by the scope of the appended claims and all equivalents thereto that would be made obvious thereby to one skilled in the art
