Abstract
A compression system for a dual material delivery assembly is described. The assembly includes a furrowing element for producing a furrow in the ground as it is towed across the ground. A fertilizer tube and a seed tube are provided for depositing fertilizer and seed at respective location in the ground. A packer wheel follows the tubes for packing earth on top of the seed. A biasing element provides a force on the furrowing element and the packer wheel. A control linkage mounts between the packer wheel and the furrowing element for controlling a distribution of the force between the furrowing element and the packer wheel.
Claims18
A dual material delivery assembly arranged to mount on a frame which is supported for movement in a forward direction, the assembly comprising:
- a mounting bracket for mounting the assembly on the frame;
- a furrowing element pivotally mounted on the mounting bracket, the furrowing element extending generally downward from the bracket to a ground penetrating end arranged to penetrate the ground for producing a furrow as the frame is moved across the ground in the forward direction;
- a first material delivery tube mounted adjacent a rearward face of the furrowing element for depositing a first material in the ground rearward of the ground penetrating end of the furrowing element;
- a packer wheel support element pivotally mounted on the furrowing element to extend generally rearward therefrom;
- a second material delivery member mounted on the wheel support element including a second delivery tube spaced rearward from the first material delivery tube, the second material delivery member having a ground engaging end offset laterally and upward from the ground penetrating end of the furrow for engaging a side of the furrow and depositing a second material in the ground spaced upward and laterally offset from the first material;
- a packer wheel mounted on the wheel support element rearward of the second material delivery member;
- a fluid actuated cylinder for providing a force on the furrowing element and the packer wheel for urging the furrowing element and the packer wheel to engage the ground;
- and
- a control linkage mounted between the furrowing element and the wheel support element for controlling a distribution of the force between the furrowing element and the packer wheel.

A dual material delivery assembly arranged to mount on a frame which is supported for movement in a forward direction, the assembly comprising:
- a furrowing element arranged to be supported by the frame for relative movement therebetween, the furrowing element extending generally downward to a ground penetrating end arranged to penetrate the ground for producing a furrow as the frame is moved across the ground in the working direction;
- a first material delivery tube mounted rearward of the furrowing element for depositing a first material in the furrow;
- a packer wheel support element arranged to be supported by the frame for relative movement therebetween, the packer wheel support element and the furrowing element being associated for common connection to the frame;
- a second material delivery tube mounted rearward from the first material delivery tube for depositing a second material in the furrow, the second material delivery tube being connected to the packer wheel support element for common movement therewith;
- a packer wheel mounted on the wheel support element rearward of the second material delivery member for common movement therewith;
- and
- a dual piston hydraulic piston cylinder having:
- a cylinder end section arranged for connection to the frame;
- a central section slidably mounted within the cylinder end and having a pivotal mount thereon pivotally coupling one of the elements thereto to transmit downward force to the element coupled thereto when the central section is displaced within the cylinder end;
- and a piston end section slidably mounted within the cylinder end and having a pivotal mount thereon pivotally coupling the other one of the elements thereto to transmit downward force to the element coupled thereto when the piston end section is displaced within the central section.
