Technical Field

[0001] The utility model relates to the technical field related to fresh cut flower pruning, in particular to a rotary fresh cut flower pruning device. Background Art

[0002] Flowers are mainly used to beautify the environment, for interpersonal communication, and as a source of food. Flowers are composed of corolla, calyx, receptacle, and stamens. They have various colors, some of which are very bright and fragrant. The reproductive organs of angiosperms (angiosperms, also known as flowering plants), whose biological function is to combine male sperm cells with female egg cells to produce seeds. This process begins with pollination, followed by fertilization, and after fertilization, seeds are formed and spread. For higher plants, seeds are their next generation, and seeds grow into flowers, which are pollinated and fertilized again, thus continuing the life of this variety of flowers. It is also the main means of distribution of various species in nature. The combination of flowers on the same plant is called an inflorescence. In a broad sense, fresh flowers can refer to all plant reproductive organs with ornamental value, while in a narrow sense, it refers to all flowering plants.

When the two blade heads 12 approach each other, the flower stems between the two blade heads 12 are squeezed and sheared, so that the device trims and cuts the flower stems of fresh cut flowers by squeezing and shearing, which greatly improves the shearing force of the device and solves the problem that when the original trimming device trims fresh cut flowers with relatively thick and hard flower stems, the high-speed rotating electric trimming knife is easily stuck inside the flower stems, thereby causing the device to burn. The cut flower stems fall into the drawer 24 through the through hole 23 on the bottom box 1 for collection. The user can pull out the drawer 24 inside the bottom box 1 through the handle 25 to process the flower stems stored in the drawer 24.
