Patent number: 9894824Abstract: A sod harvester can include a preliminary stacking head for stacking slabs of sod prior to the stacked slabs being removed from a stacking conveyor for stacking on a pallet. In this way, the stacking head can remove multiple layers of sod during a single stacking operation. The preliminary stacking head can be positioned overtop a conveyor and can be configured to pick up a slab of sod as the slab travels along the conveyor. The preliminary stacking head can then drop the slab on top of a trailing slab thereby forming a stack of slabs on the conveyor. The conveyor over which the preliminary stacking head is positioned can be an inclined conveyor that transports slabs of sod from the ground to a stacking conveyor.Type: GrantFiled: July 31, 2015Date of Patent: February 20, 2018Assignee: FireFly Automatix, Inc.Inventors: Steven R. Aposhian, Eric E. Aston, William M. Decker, Samuel H. Drake, Daniel A. Aposhian, Matthew G. Aposhian

Patent number: 9872421Abstract: A sod harvester can include an inclined stacking conveyor from which slabs of sod are removed for stacking on a pallet. The direction of incline of the stacking conveyor can be opposite that of one or more inclined conveyors used to convey sod from a cutting head to the stacking conveyor. Therefore, slabs of sod can ascend along the one or more inclined conveyors and then descend along the inclined stacking conveyor from which they are removed by the stacking head. The stacking head can also be inclined to correspond with the incline of the stacking conveyor. By inclining the stacking conveyor and the stacking head, the stacking head does not need to move vertically when removing slabs of sod from the stacking conveyor.Type: GrantFiled: July 31, 2015Date of Patent: January 23, 2018Assignee: FireFly Automatix, Inc.Inventors: Steven R.

Patent number: 9629296Abstract: A chop mechanism for a sod harvester can include a motor for rotating a cam to lift a chop frame. The cam can include a ready position in which it remains until a chopping action is started. The cam can be rotated from the ready position to a drop position in which the cam no longer supports a follower mounted to the chop frame. After the cam reaches the drop position, the rotation of the cam can be stopped to position the cam in a safe position to prevent the follower from striking the cam as the chop frame descends. Then, rotation of the cam can be resumed to return the cam to the ready position to await the next chopping action. The rotation of the cam from the ready position to the safe position and from the safe position to the ready position can be performed at different rates.Type: GrantFiled: February 18, 2015Date of Patent: April 25, 2017Assignee: Firefly Automatix, Inc.Inventors: Steven R. Aposhian, Eric E. Aston, William M. Decker, Samuel H. Drake

Publication number: 20170027100Abstract: A sod harvester can include an auxiliary stacking conveyor for stacking or folding slabs of sod on an inclined conveyor prior to the stacked/folded slabs being removed from a stacking conveyor by a stacking head. The auxiliary stacking conveyor can be configured to receive a leading slab of sod and then stack the leading slab on top of a trailing slab while the trailing slab is being advanced along an inclined conveyor. The auxiliary stacking conveyor can also be configured to partially receive a slab of sod and then reverse direction to cause the slab to be folded backwards on top of itself while being advanced along an inclined conveyor. Different configurations can be employed to cause slabs to be selectively positioned on an auxiliary stacking conveyor.Type: ApplicationFiled: July 31, 2015Publication date: February 2, 2017Inventors: Steven R.

Publication number: 20160278273Abstract: Sod harvester stacking head and stacking conveyor configurations can increase the rate at which sod can be harvested. The movement of the stacking head and/or the stacking conveyor can be controlled to maximize the rate at which the stacking head can remove sod from the stacking conveyor. A stacking head can employ multiple pick up positions. A stacking conveyor may also advance sod for pick up at varying rates. A stacking head may include a pivoting connection to allow the stacking head to rotate around a pivot during a pick up operation.Type: ApplicationFiled: June 8, 2016Publication date: September 29, 2016Inventors: Steven R.

Patent number: 9078390Abstract: The present invention extends to a conveyor system that allows the spacing between slabs on a conveyor to be controlled. Because the spacing can be controlled, a single stacking head can be used to pick up and stack multiple slabs at the same time. In this manner, a harvesting machine employing the conveyor system of the present invention can utilize a single stacking head while still harvesting sod at least as quickly as harvesting machines employing multiple stacking heads.Type: GrantFiled: March 27, 2013Date of Patent: July 14, 2015Assignee: Firefly Equipment, LLCInventors: Steven R.

Patent number: 9022720Abstract: The present invention extends to a stacking mechanism having electrical actuators for stacking slabs of sod on a sod harvesting machine. The electrical actuators allow the stacking head to be driven in three axes. The stacking mechanism also includes position feedback sensors for reporting the position of the stacking head to enable precision when operating the stacking head at a fast rate. The stacking mechanism of the present invention also provides temporary pallet support wings to enable the continued stacking of slabs of sod on one pallet even while another pallet is being dropped from the sod harvesting machine.Type: GrantFiled: March 27, 2013Date of Patent: May 5, 2015Assignee: Firefly Equipment, LLCInventors: Steven R.

Patent number: 8978779Abstract: An articulated cutting head and conveyor mount for sod harvesting machines. The invention provides a linkage design that can provide many benefits including: allowing the operator to see the cutting operation, enabling the high lifting of the cutting head for service and maneuvering, managing the vertical bending load of the ground reference roller, providing high transverse stiffness, maintaining the position of the conveyor relative to the cutting head. The linkage design can include fewer parts than previous designs while still being robust and durable. As such, cutting heads employing the linkage design of the present invention can produce higher quality slabs with less service and maintenance than when using current designs.Type: GrantFiled: March 27, 2013Date of Patent: March 17, 2015Assignee: FireFly Equipment, LLCInventors: Steven R.

Patent number: 8851278Abstract: The present invention extends to a lifting system for lifting a portion of a conveyor. The lifting system maintains the length of the conveyor while changing the shape of the conveyor to lift the top surface of the conveyor belt towards a stacking head. This design facilitates the quick lifting and lowering of slabs of sod while minimizing the stress on the sod harvesting machine.Type: GrantFiled: March 27, 2013Date of Patent: October 7, 2014Assignee: FireFly Equipment, LLCInventors: Steven R.
