Soil cultivating implement including dispenser and support roller

Abstract

A rotary harrow or cultivator has a frame that supports a plurality of soil working members arranged in a row that extends transverse to the direction of travel. The frame includes two linked portions and one portion is connected to a rear support roller that regulates the working depth of the implement. A dispensing mechanism, including a plurality of delivery members, is mounted on the implement and the delivery members are carried on a common support that extends transverse to the direction of travel. The common support is interconnected to the roller so that material is dropped as the roller levels the worked soil.

Description

Claims

1. A cultivating implement comprising a frame and a plurality of mechanically driven soil working members rotatably mounted on an elongated portion of said frame, said elongated portion extending transverse of the direction of travel and being pivotably connected to a second portion of the frame, said elongated frame portion being interconnected to and at least partly supported by a ground engaging roller that governs the working depth of said soil working members and said roller being positioned to the rear of the soil working members, a mechanism on said frame for applying material onto or/and into the soil being mounted on said second frame portion and said mechanism comprising hopper means with a plurality of downwardly extending delivery members that receive material from the hopper means, a common elongated support for said delivery members being positioned to the rear of said soil working members and in front of the rear side of said roller, the lower portions of said delivery members opening above said roller and being pivoted to said support, spaced apart arms interconnecting said roller to the opposite lateral sides of said elongated frame portion and said support being connected to said arms, said delivery members being movable relative to said support to avoid damage when the frame portion pivots during travel.

2. An implement as claimed in claim 1, wherein the said mechanism comprises an elongated hopper that extends transverse to the direction of travel and said delivery members are tubes that communicate with a lower region of the hopper, said tubes being mounted on said common support and being independently movable relative to that support.

3. An implement as claimed in claim 2, wherein at least one tube is positioned between two parts of a supporting bracket secured to said common support, a lower side of said tube having lug means pivotably connected to that bracket.

4. An implement as claimed in claim 3, wherein said lug means is pivotably connected to a pin held between limbs of a corresponding bracket, said one tube being displaceable laterally between said limbs.

5. An implement as claimed in claim 2, wherein sid tubes are freely movable, upwardly and downwardly about an axis that extends substantially horizontally perpendicular to the direction of travel.

6. An implement as claimed in claim 5, wherein the hopper houses rotatable delivery means and a drive from at least one ground engaging wheel on said second frame portion engages and rotates said delivery means.

7. An implement as claimed in claim 6, wherein said rotatable delivery means has opposite ends that are driven by two corresponding ground engaging wheels.

8. An implement as claimed in claim 7, wherein a transmission between each ground engaging wheel and said rotatable delivery means comprises a shaft having universal joints at its opposite ends.
