Apparatus for installing a silt fence

摘要

A frame is supported for vertical movement by a vehicle and has an inclined shaft supporting a roll of silt fence material. The frame also supports a vertical plow plate having a forward edge surface and an inclined rearward edge surface spaced adjacent an inclined foldover member to define a narrow gap which receives fence material directly from the roll. The plow supports a removable, flexible and resilient panel which projects rearwardly to extend within a slit formed in the ground by the plow plate to prevent debris from snagging the material. The inclined shaft is adjustable vertically, and the roll is adjustable axially on the shaft to maintain an edge of the fence material adjacent the bottom of the plow plate. The frame may also support a rotatable and vertically movable boom from which depends an impact hammer for installing stakes in the ground adjacent the fence.

主权项

1. Apparatus for inserting into the ground a longitudinal edge portion of an elongated strip of flexible silt fence material extending from a supply roll, said apparatus comprising
a frame including a connector for connecting said apparatus to a vehicle, said frame supporting a shaft having an axis and supporting a supply roll of said silt fence material, a vertical plow plate supported by said frame and having a forward edge surface and an inclined linear rearward edge surface, said frame and a lower portion of said plow plate supporting a foldover member, positioned behind said rearward edge surface of said plow plate and defining a gap between said foldover member and said rearward edge surface, said gap adapted to receive said silt fence material extending from said supply roll and for folding the material around said foldover member with an edge portion of the material extending into a slit formed into the ground by said plow plate in response to forward movement of said apparatus with the vehicle, a flexible and resilient elastomeric protector panel connected to said plow plate and projecting rearwardly from said rearward edge surface and positioned adjacent said silt fence material entering said gap and within the slit in the ground, and said protector panel being effective to block rocks and debris from entering said gap with said material and prevent disrupting the movement of the material through said gap.
