Abstract
An excavating implement adapted to be pulled behind a vehicle to form a ditch or trench. The implement includes a cutting trough for cutting through soil and a soil removing structure mounted with and extending into the cutting trough for receiving soil from the trough. The soil removing structure forms a passageway for soil to pass laterally beyond the cutting trough so that soil may be removed from the trough while the trough is cutting. A depth control structure controls the depth at which the cutting trough cuts through the soil, thereby controlling the depth of the ditch made by the apparatus.
Claims1
An excavating implement adapted to be pulled by a vehicle, comprising:
- cutting trough means for cutting through soil;
- soil removing means mounted with and extending into said trough means for receiving soil from said trough means and forming a passageway for soil to pass laterally beyond said trough means;
- hitch means mounted with said trough means for connecting said trough means to a vehicle;
- depth control means for controlling the depth at which said cutting trough means cuts through soil comprising skid means mounted with said cutting trough means for supporting said cutting trough means at a desired depth in the soil;
- mounting means for mounting said skid means with said cutting trough means in any of a plurality of selected positions to control the depth in the soil at which said skid means supports said cutting trough means;
- said soil removing means forming a first passageway for soil to pass laterally beyond a first side of said cutting trough means and a second passageway for soil to pass laterally beyond a second side of said cutting trough means;
- diverting means mounted with said soil removing means for alternatively diverting soil to said first passageway, to said second passageway, and to both first and second passageways;
- said diverting means comprising a baffle plate pivotally mounted with said soil removing means for movement between a first position blocking said second passageway, a second position blocking said first passageway, and a third position blocking neither said first passageway nor said second passageway;
- and
- the cutting trough means comprising trough means having a substantially U-shaped cross-sectional configuration and cutting edge attachment means mounted with the forward edge of said trough means for cutting through soil.
