Description

Technical Field

[0001] The present application belongs to the technical field of tobacco leaf stripping tools, and more specifically, relates to a portable electric leaf stripping tool for harvesting tobacco leaves with stems. Background Art

[0002] With the widespread adoption of stem-to-stalk curing for flue-cured tobacco, farmers now primarily harvest tobacco from the field using sickles to chop the stems. The leaves and stems are then transported together to the curing barn for curing, a practice known as on-stalk curing. To increase the usability of the upper tobacco leaves, tobacco-producing regions are actively promoting on-stalk curing. This involves harvesting the top 4-7 leaves of fresh tobacco all at once, stemmed, and then curing them with the stems intact. After curing, the on-stalk leaves need to be peeled, a crucial step in this technique. After curing, the on-stalk leaves must be separated from the stems before they can be graded, sold, and purchased. Currently, the most common methods for peeling the leaves are manual pulling and tool peeling. Manual pulling is labor-intensive and inefficient, and the peeled tobacco leaf petioles often retain some of the stem bark, increasing the weight of non-tobacco matter. Tool peeling primarily involves cutting the leaf petioles with scissors, but prolonged cutting can lead to hand fatigue and reduced efficiency. Utility Model Content

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0020] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0021] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0023] like Figure 1-Figure 2As shown, a portable electric leaf stripping tool for harvesting tobacco leaves with stems, provided in an embodiment of the present application, will now be described. The portable electric leaf stripping tool for harvesting tobacco leaves with stems comprises a handle 1 and a cutting section 2. The handle 1 is held in one hand by a worker and is equipped with a switch 3, a battery 4, a circuit board 5, and a motor 6. The switch 3 is used to control the on / off operation of the motor 6, and the battery 4 is used for power supply. The circuit board 5 is used to electrically connect the switch 3, battery 4, and motor 6. The cutting section 2 is equipped with a saw blade 8, a rear protective cover 9, and a front movable baffle 10. The saw blade 8 is arranged to rotate and is connected to the motor 6 via a worm gear 7. This allows the motor 6 to rotate. The worm gear 7 can also be used to adjust the position of the motor 6 so that the output shaft of the motor 6 is perpendicular to the rotation axis of the saw blade 8. The front movable baffle 10 and rear protective cover 9 provide protection, preventing the saw blade 8 from being exposed to the outside and potentially injuring workers or other objects. The front movable baffle 10 is elastically movable so that the saw blade 8 and the front movable baffle 10 can move relative to each other. A cutting groove 11 is provided on the front movable baffle 10 for the saw blade 8 to extend out. When not subjected to external force, the saw blade 8 is located on the inner side of the front interactive baffle. During cutting, the outer side of the front movable baffle 10 presses against the cutting position of the tobacco leaf petiole. By continuing to press the handle 1, the saw blade 8 extends out of the cutting groove 11 to cut the tobacco leaf petiole outside the front movable baffle 10. The operation is simple.

[0024] Specifically, the elastic setting of the front movable baffle 10 is achieved through the following structure. A fixed shaft 12 is also provided on the shell of the handle part 1 or the cutting part 2, and a fixed baffle 13 is fixed on the fixed shaft 12. The front movable baffle 10 is an L-shaped plate. A movable block 14 is provided at the bottom of the front movable baffle 10. The movable block 14 is sleeved on the fixed shaft 12, and a spring 15 is sleeved on the fixed shaft 12 between the movable block 14 and the fixed baffle 13. When no external force is applied, the spring 15 is in a natural state. The spring 15 can keep the movable block 14 and the fixed baffle 13 at a fixed interval. At this time, the saw blade 8 is located on the inner side of the front movable baffle 10; when cutting, the outer side of the front movable baffle 10 is in contact with the petiole of the tobacco leaf, and the pressing force is continuously applied. The spring 15 is compressed, and the saw teeth move forward relative to the front movable baffle 10 in the direction close to the tobacco leaf, and extend through the cutting groove 11 to cut the petiole of the tobacco leaf. When the cutting is completed and the displacement is completed, the spring 15 automatically resets to ensure that the rotating saw blade 8 will not be exposed, thereby ensuring safety in use.

[0025] In this embodiment, one end of the fixed shaft 12 is fixed to the handle portion 1 or the cutting portion 2, and the other end is provided with a limit block 16 by screwing. The limit block 16 is detachable, which makes it convenient to sleeve the front movable baffle 10 and the spring 15 on the fixed shaft 12. The front movable baffle 10 can also be used to cut tobacco leaf petioles after being disassembled, but the safety will be greatly reduced. In this embodiment, the fixed shaft 12 can be fixed to the shell of the handle portion 1 or the cutting portion 2, or can be detachably fixed by a nut. Among them, the detachable fixing method is: if the shell of the handle portion 1 is two half shells that are spliced and snap-fitted, both ends of the fixed shaft 12 are provided with external threads, and a socket is provided on the shell. After the fixed shaft 12 is inserted through the socket, a nut is screwed inside the shell to limit and fix the fixed shaft 12.

[0026] Preferably, the stopper 16 is a spherical block, which is aesthetically pleasing, and the curved surface provides increased comfort and safety. In this embodiment, the fixed shaft 12 has a rectangular or square cross-section, and the movable block 14 is provided with a rectangular or square hole. This allows the front movable baffle 10 to move only linearly along the fixed shaft 12, preventing deflection.

[0027] In this embodiment, the battery 4 is a lithium battery 4; the lithium battery 4 can be a plug-in battery module 4 for easy replacement. The switch 3 is a push-button switch 3, with a single press for on and a second press for off. Alternatively, a switch 3 with multiple positions can be selected to adjust the speed of the saw blade 8. The rear guard 9 is an aluminum alloy guard with a certain degree of deformation resistance. The front movable baffle 10, movable block 14, and fixed shaft 12 are all made of steel to ensure structural strength and deformation resistance.

[0028] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
