Abstract
An encapsulated seed planting device for planting a seed that is encapsulated in a water soluble cover. The encapsulated seed planting device comprises a frame and a support device for supporting the frame above a surface. A planting unit is provided that comprises a cartridge for receiving the seed. A compression device is coupled to the cartridge for holding the seed. A piston is positioned in a facing relationship with the cartridge. The piston is configured to push the seed out of the cartridge and into the surface. A cylinder is positioned in a facing relationship with the piston. The cylinder is configured to move the piston. A control device is provided for controlling operation of the cylinder.

An encapsulated seed planting device for planting a seed that is encapsulated in a water soluble cover, the encapsulated seed planting device comprising:
- a frame;
- a support device for supporting the frame above a surface;
- a planting unit comprising:
- a cartridge for receiving the seed;
- a compression device coupled to the cartridge for holding the seed;
- a piston positioned in a facing relationship with the cartridge, the piston configured to push the seed out of the cartridge and into the surface;
- and
- a cylinder positioned in a facing relationship with the piston, the cylinder configured to move the piston;
- and
- a control device for controlling operation of the cylinder;
- wherein the support device comprises a support device cylinder to move the piston relative to the surface.
An encapsulated seed planting device for planting a seed that is encapsulated in a water soluble cover, the encapsulated seed planting device comprising:
- a frame;
- a support device for supporting the frame above a surface, the support device comprising a support device cylinder to move the frame relative to the surface;
- a planting unit comprising:
- a cartridge for receiving the seed;
- a compression device coupled to the cartridge for holding the seed;
- a piston positioned in a facing relationship with the cartridge, the piston configured to push the seed out of the cartridge and into the surface;
- and
- a cylinder positioned in a facing relationship with the piston, the cylinder configured to move the piston;
- and
- a control device for controlling operation of the cylinder and the support device cylinder, the control device comprising a data storage device and an electronic data processor, the data storage device configured for storing instructions that are executable by the electronic data processor to cause the electronic data processor to determine a cylinder output and provide a cylinder signal to the cylinder to move the piston and to determine a support device cylinder output and provide a support device cylinder signal to the support device cylinder to move the piston up or down relative to the surface to achieve a desired planting depth.
A method for controlling an encapsulated seed planting device, the encapsulated seed planting device comprising a frame, a support device for supporting the frame above a surface, the support device comprising a support device cylinder to move the frame relative to the surface, a planting unit comprising a cartridge for receiving the seed, a compression device coupled to the cartridge for holding the seed, a piston positioned in a facing relationship with the cartridge, the piston configured to push the seed out of the cartridge and into the surface, and a cylinder positioned in a facing relationship with the piston, the cylinder configured to move the piston, the method comprising:
- determining a cylinder output;
- providing a cylinder signal to the cylinder to move the piston;
- determining a support device cylinder output;
- and
- providing a support device cylinder signal to the support device cylinder to move the piston up or down relative to the surface to achieve a desired planting depth.
