Patent Application
20210386022
The present invention relates to agricultural trimming tools, and more specifically to an electric powered rotary trimming tool.
Pruning is an essential garden task that keeps plants healthy and tidy. Tools used for pruning include garden scissors, secateurs, garden knives, hedge shears, and loppers. Garden scissors allow one to make delicate and precise snips to flower stems, for example. Secateurs area also known as pruners, had pruners, and pruning shears. Hedge shears and loppers typically are slightly larger and used for slightly heavier cutting tasks.
In some agricultural applications, flowers, including dried flowers, may have small dried leaves around the flower. It may be desired to remove these dried leaves. Although this may be done with garden scissors, that may be a laborious and time-consuming task.
What is called for is a small, portable, electrically powered handheld trimmer which can trim extraneous material from such dried flowers, and other agricultural products and plant materials.
An electrically powered rotary trimmer adapted to trim external portions of an agricultural or other plant product. The trimmer may include an electric motor which rotates two or more trimming portions. The trimmer may include a handle with a battery. The trimmer may include a trim guard which may be rotatably adjustable. The trimmer may be adapted to plug into an external power source, which may be an external battery or a cellular telephone.
In some embodiments of the present invention, as seen in
Power provided to the portable electric rotary trimming tool may be routed through the power coupling 102 and to an electric motor residing within the main body portion 101b. In some aspects, the electric motor is a dc brush motor. The motor shaft 106 may extend out from the main body portion 101b and be coupled to a trimming head 107. The trimming head 107 is driven in a rotary fashion by the electric motor. The trimming head 107 may have flexible trimmer extensions 107a which are rigid enough to trim leaves and other lighter aspects of an agricultural product, or other plant product, while being flexible. A trimmer shroud 103 is coupled to the main body portion 101b of the tool body 101. The shroud is adapted to deflect trimmed portions of the agricultural product, in order, for example, to direct the trim waste in a direction, which may be a direction away from the user. The trimmer shroud 103 may be of a modified conical shape, although with an enlarged lower portion to allow clearance to the rotating trimmer extensions. The trimmer shroud 103 may not be axial symmetric but instead be only a partial axially rotated shape such that material ejected during trimming is deflected by the shroud but allowed to be ejected in that direction in which the shroud is not present. In some aspects, the trimmer shroud 103 is rotatably coupled to the main body portion 101b of the tool body 101 along an interface 105. The interface may be adapted to allow for the rotation of the trimmer shroud 103 relative to the tool body 101, while also having enough friction to retain that position once achieved via rotation by hand. The trimmer shroud 104 may have an interface area 104 adapted to mate with the interface 105 of the tool body 101, such as an enlarged lip adapted to press into a mating groove, for example.

In some embodiments of the present invention, as seen in
As evident from the above description, a wide variety of embodiments may be configured from the description given herein and additional advantages and modifications will readily occur to those skilled in the art. The invention in its broader aspects is, therefore, not limited to the specific details and illustrative examples shown and described. Accordingly, departures from such details may be made without departing from the spirit or scope of the applicant's general invention.
