US 11,432,478 B2 · Film deployer, improved trash whipper and improved planter

Abstract

The present invention provides a ground engaging film roller 30.2 having a generally horizontal axis of rotation and an outer circumference for engaging ground, the roller having opposed outer ends 30.21 of a larger circumference than the circumference of portions 30.22 located between the opposed ends. The present invention also provides a film deployment system having a ground engaging film roller as described above, which is rotationally mounted to a frame 30.1, the ground engaging film roller 30.2 receiving film from above and to a front location of the roller, and passing between a film locating roller 30.3 and the ground engaging roller 30.2, the ground engaging roller 30.2 shaping the ground it engages by forming a channel in ground at the opposed ends 30.21 of the roller 30.2 for the film to be located as it leaves engagement with the ground engaging roller 30.2. The present invention also provides an agricultural or horticultural implement 10, 30 for performing an agricultural or horticultural process, the implement 10,30 including whipper arrangement 50 at a location forward of where the process will be performed. The agricultural or horticultural implement 10, 30 can be such that to the rear of where the process is performed there can located film deployment system 30 as described above.

Dependent claims

A film deployment system having a ground engaging film roller which has a generally horizontal axis of rotation and an outer circumference for engaging ground, said ground engaging film roller having opposed outer ends of a larger circumference than the circumference of portions located between the opposed ends, said ground engaging film roller being rotationally mounted to a frame, said ground engaging film roller receiving film from above and to a front location of said ground engaging film roller, and passing between a film locating roller and said ground engaging film roller, said ground engaging film roller shaping the ground it engages by forming a channel in ground at the opposed ends of the ground engaging film roller for said film to be located as it leaves engagement with said ground engaging film roller, wherein there is positioned near to said opposed ends of said ground engaging film roller one or more of the following:

an insertion disc which is adapted to simultaneously form a deeper channel in said channel formed by said ground engaging film roller and to push said film into said deeper channel;
an insertion disc the position of which is adjustable laterally so as to position same at different parts of said channel formed by said opposed ends of said ground engaging film roller;
an insertion disc which cooperates with a scraper;
an insertion disc which cooperates with a shielding brush;
an insertion disc which follows said opposed ends of said ground engaging film roller which dictates the width of clear film left exposed above soil, after said system has passed.

A film deployment system having a ground engaging film roller which has a generally horizontal axis of rotation and an outer circumference for engaging ground, said ground engaging film roller having opposed outer ends of a larger circumference than the circumference of portions located between the opposed ends, said ground engaging film roller being rotationally mounted to a frame, said ground engaging film roller receiving film from above and to a front location of said ground engaging film roller, and passing between a film locating roller and said ground engaging film roller, said ground engaging film roller shaping the ground it engages by forming a channel in ground at the opposed ends of the ground engaging film roller for said film to be located as it leaves engagement with said ground engaging film roller wherein said system is located in one of the following:

a film deploying implement which is adapted to deploy film;
a seed planter having a trailing film deploying implement or system;
an agricultural or horticultural process implement having a trailing film deployment implement or system;
a film deploying implement in which there is located a weight pin mechanism which detects how much weight is being carried and or applied to the ground by said film deployment implement, and compensates by application of hydraulic pressure to a hydraulic cylinder to apply a desired weight to be carried and or applied to the ground.

1 more element

An agricultural or horticultural implement wherein there is located a film deployment system having a ground engaging film roller which has a generally horizontal axis of rotation and an outer circumference for engaging ground, said ground engaging film roller having opposed outer ends of a larger circumference than the circumference of portions located between the opposed ends, said ground engaging film roller being rotationally mounted to a frame, said ground engaging film roller receiving film from above and to a front location of said ground engaging film roller, and passing between a film locating roller and said ground engaging film roller, said ground engaging film roller shaping the ground it engages by forming a channel in ground at the opposed ends of the ground engaging film roller for said film to be located as it leaves engagement with said ground engaging film roller, wherein said implement further includes a trash whipper arrangement comprising a pair of angularly oriented ground engaging whipper coulters mounted to a forward end of a pivoted four bar linkage which has two stationary pivots mounted to a support which carries said whipper, which when in use has said two stationary pivots located in a generally horizontal plane.
