This invention is in the field of plant or herb component harvesting, and the field further relates to one or more novel devices and methods for using one or more such devices to strip buds or flowers, or both from a useful plant that forms flowers or buds.
Many flowers and buds are edible or otherwise useful in nutrient preparations. In particular, rose flowers, especially their buds (not yet fully blossomed flowers), are very high in Vitamin C and other trace nutrients. In fact, the amount of Vitamin C in rose buds far surpasses amounts in many fruits and vegetables. Isolated flower buds are edible or otherwise consumable, for example, they may be steeped to provide a tea high in the desired nutrients.
Other examples of nutrient flowers are orchids, cactus flowers, lotus and the like. The use of green leaves, flowers or buds in cooking or other consumables is essential for the preparation of numerous side dishes for various styles of cooking. Example leaves are herbs and plants such as parsley, basil, coriander, mint, and many others that can be incorporated into recipes both for health benefits and for the creation of different tastes to bring out the natural flavors of the foods.
A still further example of nutrient flowers are cannabis and hops. Each produces flower bracts, often called either flowers or buds, which are used for nutrition, medicine, recreational consumption and/or culinary purposes.
The flowers, buds and leaves are conventionally picked from the stems of the plants by hand which requires a great deal of time and effort. In the cannabis industry this process is referred to as “bucking” or “debudding.” It can performed by hand with scissors or clippers. The hand picking procedure demands continuous concentration and often requires more than one person to yield the amount of leaves, flowers or buds required for certain recipes. There are known devices for cutting and chopping plants for cooking, and a device is described in U.S. Pat. No. 7,907,687 to Al-Harbi that was adapted to remove leaves from stems of herbs and plants. The Al-Harbi devices have flexible comb-like tines that catch leaves on the distal ends of plants as they are drawn through the flexible comb teeth in a first step by pulling on the proximal ends of the stems, and a blade to then lifted to dislodge the leaves caught in the flexible comb tines. However, rose buds stems are stronger and would not be efficiently stripped from the stems without losing the flexible nature of the tines. Further, the need to use a rotating arm in a second step to remove the buds or flowers from the stems is inefficient or could damage the buds.
There are also known machines for removing flowers or buds, referred to in the cannabis industry as “bucking machines.” Such machines are typically electric or gasoline driven, and use belts, combs or other grabbing devices to grab and pull the cut end of a flower stem through a small hole in a metal plate, thereby stripping off the buds as they contact the front of the plate. This presents a disadvantage, in that the size of the hole must fit the widest part of the stem being bucked. For long stems, which narrow significantly over their length, the hole may be able to buck buds on the lower and thicker part of the stem, but may be too wide, and therefore miss, buds on the higher and thinner end of the stem. This also frequently results in the bucking machine drawing a number of small, unbucked buds into the belts, combs or grabbing devices. Because cannabis buds are normally sticky or tacky with resin, these unbucked buds can eventually “gum-up” the mechanisms of known mechanical bucking machines. Further, currently known bucking machines are expensive, costing hundreds or thousands of dollars. Moreover, they are prone to breakdowns and heavy maintenance requirements, due to the number of moving parts and the need to adjust or replace belts, combs or grabbing devices. Still further, they are require access to an electrical power source or fuel. Additionally, each bucking machine can typically only be used by a single operator at a time. Further, unless the operator is skilled at setting up and adjusting the machine for the particular size and type of buds being bucked, bucking machines can damage buds, if they are removed too forcefully, can fail to remove smaller buds, or can break off stems and leaves prematurely, resulting in the need to further hand-sort the output of the bucking machine.
Finally, if a bucking machine breaks down, it can jeopardize the quality of the finished cannabis product. Typically, cannabis buds are bucked after a limited drying period, to ensure that they are not green, but before they have fully dried. Then, bucked buds are placed in airtight packaging to reduce further loss of moisture and/or further evaporation of cannabinoids. For many growers, the timing of the bucking operation is critical, to ensure that their cannabis buds are dry enough to process, but no drier. Overly dried cannabis buds become crumbly and can break into small pieces, which are normally seen as undesirable by consumers. Further, longer drying times can result in the evaporation and loss of desirable cannabinoids, such as THC, CBD and the aromatic terpenes that give cannabis its unique flavor and smell. Thus, any failure of a mechanical bucking machine during the critical moisture window that delays the bucking operation can result in reduced quality, and therefore less valuable, cannabis buds.
Accordingly, there is a need for an improved, efficient, cost-effective, reliable, low maintenance, labor saving device and method for removing flowers or buds from a plant stem in a single step. Optionally, there is a need for an improved device or method for removing leaves from the stems of herbs or plants, especially woody plant herbs, such as rosemary, thyme, cannabis, hops, and the like.

With reference to
The various embodiments of the device, shown in
Applicant has discovered that use of a flower stripping device such as illustrated and disclosed herein can speed up the bud stripping process for harvest of cannabis buds up to 10 fold over bucking by hand with a pair of scissors. In some experiments, Applicant has discovered that use of a flower stripping device such as illustrated and disclosed herein can enable a user to buck 6-8 pounds of cannabis per hour, versus approximately one pound per hour using scissors. Moreover, use of the flower stripping device such as illustrated and disclosed herein can make it economical to buck flower stalks with small or few buds that would otherwise not be worthwhile bucking by hand. Currently it is uneconomical to remove all of the smaller buds and flowers by hand use of scissors, due to the cost of labor. With embodiments disclosed herein, a user may now simply pull the stem up through the notches and remove nearly 100% of the buds and flowers easily and quickly without damage to the buds and flowers.
Moreover, compared to the bucking machines currently known, the flower stripping device such as illustrated and disclosed herein has no moving parts, has a self-sharpening cutting edge, is self-cleaning as subsequent stems are drawn through it, uses no electricity and is extremely rugged and durable.
