The invention is a device for the safe and efficient collection of debris displaced across a collection field. Utilizing a plurality of spikes which pierce and penetrate articles of debris, the invention contemplates the accumulation of articles of debris on the spikes. When the device has become loaded with debris, the device self ejects the debris using a compression spring force trigger mechanism.

We claim: 1. A debris collection device comprising: a handle, a shaft fixedly attached to said handle, a trigger ejection system utilizing a compression spring slidingly attached to and internal to said shaft, and a collection head fixedly attached to said shaft and to said trigger ejection system,
We claim: 1. A debris collection device comprising: a handle, a shaft fixedly attached to said handle, a trigger ejection system utilizing a compression spring slidingly attached to and internal to said shaft, and a collection head fixedly attached to said shaft and to said trigger ejection system, wherein said trigger ejection system and said collection head operate from a loaded position where the compression spring is tightly compressed to an ejected position where some of the spring force of the compression spring has been released such that any debris that may have been collected on the collection head while in the loaded position is accordingly released when actuated into the ejected position and, wherein said handle is ergonomically curved with respect to said shaft such that it comprises a power grip. 2. The debris collection device of claim 1 wherein said shaft is cylindrical and hollow and further comprises an attachment plate, having a pair of attachment holes disposed thereon, for attachment to the collection head, a trigger slot in the shape of an inverted fish hook comprising a lower tail end and a hook end, and an indention point just below the lower tail end of the trigger slot; and wherein said trigger ejection system further comprises a trigger handle, a trigger actuator, a pusher rod, a spring pusher, and a spring stop, said pusher rod being housed inside said shaft and fixedly attached to an ejection plate portion of said collection head, said trigger actuator fixedly attached to said pusher rod, said trigger handle fixedly attached to said trigger actuator, said spring stop fixedly attached to said pusher rod, said spring pusher slidingly attached to said pusher rod and movable within the portion of said shaft below the indention point, said compression spring slidingly attached to said pusher rod and located between said spring pusher and said spring stop, said trigger handle extending through said trigger slot such that said trigger handle is located in the hook end of said trigger slot when in the loaded position and in the lower tail end of said trigger slot when in the ejected position. 3. The debris collection device of claim 2 wherein said collection head further comprises a backing plate, a spike plate, an ejection plate, a plurality of spikes, and a plurality of shoulder bolts; each of said spikes having a cylindrical shape and comprising a shaft portion and a pair of opposed ends having a rounded head at one end and a sharpened point at the other end wherein the circumference of the rounded head is larger than the circumference of the shaft portion of said spike; said backing plate having a central hole through which the pusher rod of the trigger ejection system passes, a pair of attachment holes through which a pair of attachment screws, having passed through the attachment holes of the attachment plate of the shaft, pass, and a pair of slots through which the shoulder bolts pass; said spike plate having a central hole through which the pusher rod of the trigger ejection system passes, a plurality of counter sunk holes, a pair of threaded holes which mesh with the attachment screws, and a pair of shoulder bolt holes through which the shoulder bolts pass, each of said counter sunk holes having a large diameter sized slightly larger than the diameter of the rounded head of the spike and a small diameter sized slightly larger than the diameter of the shaft of the spike, and each of said counter sunk holes having a depth sized so that when the spike is inserted, the top portion of said rounded head of said spike is flush with the top surface of said spike plate; said ejection plate having a plurality of ejection holes through which the spikes pass when the device is operated from the loaded position to the ejection position, a plurality of threaded shoulder bolt holes which mesh with a threaded portion of the shoulder bolts, and a central hole for fixed attachment to the pusher rod of said trigger ejection system. 4. The debris collection device of claim 3 further comprising a trigger slot guard, said trigger guard having a cylindrical shape with a diameter slightly larger than the exterior diameter of said shaft, having a height twice as large as the length of said trigger slot, and having centrally disposed a hole slightly larger than the trigger handle of said trigger ejection system such that the trigger handle of said trigger ejection system passes through said hole and such that the trigger slot guard moves with the trigger handle when trigger handle is released from the hook end of said trigger slot and moves, via the released spring force of said compression spring, to the lower tail end of the trigger slot.
