Description

Technical Field

[0001] The utility model relates to the technical field of flue-cured tobacco, in particular to a multifunctional ring cutter for flue-cured tobacco. Background Art

[0002] The main characteristics of flue-cured tobacco are that the plants are tall and the leaves are distributed sparsely and evenly. Generally, the plant height is 120-150 cm, with 20-30 leaves per plant. The leaves are thick, the stem is moderate, and the quality of the middle part is the best. Too much nitrogen fertilizer should not be applied in cultivation. The leaves mature from bottom to top and are harvested in batches.

[0003] Such as "The influence of girdling treatment on the physical and chemical components of flue-cured tobacco leaves during the mature period" with the article number 1006-060X(2007)04-0064-03, "The influence of root cutting and girdling on the cycle and accumulation of potassium, calcium and magnesium in tobacco plants" with the paper number 2010-1893, and "The influence of girdling on the yellowing of flue-cured tobacco during maturity and the quality of cured tobacco" in the 9th issue of the 30th volume of Southwest China Journal of Agricultural Sciences in 2017 all show the necessity of girdling flue-cured tobacco.

[0004] When harvesting flue-cured tobacco, it needs to be cut at an appropriate height. However, the existing cutting knives require workers to judge the cutting height based on subjective consciousness, so the cutting height is inaccurate, reducing the quality of flue-cured tobacco. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem that in the existing technology, the cutting knife requires workers to judge the cutting height based on subjective consciousness, so the cutting height is inaccurate, reducing the quality of flue-cured tobacco, and a multifunctional ring cutter for flue-cured tobacco is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: a multifunctional ring cutter for flue-cured tobacco, including two handles. One end of each of the two handles is fixedly connected with a disc. One side of each of the two discs is fixedly connected with a first mounting plate and a second mounting plate respectively. The two discs are arranged in a staggered manner. The same rotating shaft passes through the interiors of the two discs in a rotating manner. Grooves are formed on one side of each of the first mounting plate and the second mounting plate. A clamping assembly for clamping flue-cured tobacco is arranged inside the grooves;

[0007] One end of the first mounting plate is provided with a cutting assembly for cutting flue-cured tobacco;

[0008] One end of the second mounting plate is fixedly connected with an arc-shaped piece. A height-determining assembly for determining the cutting height is arranged on one side of the arc-shaped piece.

[0009] In a possible design, the clamping assembly includes a limiting block slidably connected to the inner wall of one side of the groove. The same second spring is fixedly connected between one side of the limiting block and the inner wall of one side of the groove.

[0010] In a possible design, the cutting assembly includes a T-shaped groove formed on one side of the first mounting plate. A T-shaped block is clamped inside the T-shaped groove, and a cutting blade is fixedly connected to one side of the T-shaped block.

[0011] In a possible design, two symmetrically arranged rectangular holes are formed on one side of the first mounting plate. A clamping block slidably penetrates through the inside of the rectangular hole. Two symmetrically arranged clamping grooves are formed on one side of the T-shaped block, and the clamping grooves are engaged with the clamping blocks. The other ends of the two clamping blocks are fixedly connected to the same cross plate. A circular groove is formed on one side of the first mounting plate, and a same tension spring is fixedly connected between the inner wall of one side of the circular groove and one side of the cross plate.

[0012] In a possible design, the height-determining assembly includes a mounting block fixedly connected to one side of the arc-shaped piece. An inner rod is welded to the bottom of the mounting block. A sleeve is slidably sleeved on the outer wall of the inner rod. A locking screw is threadedly penetrated through one side of the sleeve, and one end of the locking screw abuts against the outer wall of the inner rod.

[0013] In a possible design, the same first spring is fixedly connected between the two grips.

[0014] In this application, during use, the staff holds the two grips. By pressing the two grips, at this time, the grips drive the disc to rotate around the rotating shaft, and then drive the first mounting plate and the second mounting plate to rotate and approach each other, so that the cutting blade can cut the flue-cured tobacco.

[0015] And during use, the height can be adjusted by rotating the locking screw. At this time, the height of the sleeve can be adjusted. Then, during harvesting, the bottom of the sleeve is abutted against the ground, so that the height of each cut can be kept consistent, the accuracy of harvesting can be improved, and the quality of the flue-cured tobacco can be guaranteed.

[0016] When replacing the cutting blade, the cross plate can be first pulled horizontally. The cross plate drives the two clamping blocks to move horizontally, and the cross plate stretches the tension spring. At this time, the clamping blocks are removed from the inside of the clamping grooves, and the braking state of the T-shaped block can be released. At this time, the cutting blade is pulled horizontally, and then the cutting blade can be removed from the inside of the T-shaped groove, which is convenient for replacing the cutting blade.

[0017] Beneficial effects: In this utility model, there is a quick-release blade structure. This application is provided with a unique quick-release blade structure, which makes the replacement of the blade more convenient. In actual operation, the user does not need to rely on complex tools, and only through simple operations, the installation and disassembly of the blade can be quickly completed, which greatly improves the work efficiency and reduces the maintenance cost.

[0018] In this utility model, the function of accommodating flue-cured tobacco with multiple diameters: The ring cutter is carefully designed to be able to accommodate flue-cured tobacco with multiple diameters. Its adjustable structure can adapt to flue-cured tobacco plants of different specifications, improving the versatility and practicality of the tool and providing great convenience for flue-cured tobacco growers;

[0019] In this utility model, the device for setting the ring cutting height: This application is equipped with a device for setting the ring cutting height. Users can accurately adjust the ring cutting height according to specific ring cutting requirements, ensuring the accuracy and consistency of the ring cutting operation, thereby improving the quality and yield of flue-cured tobacco;

[0020] In this utility model, the ergonomic design: It fully considers the operating habits of users and the principles of ergonomics, and has been optimized in terms of shape and size. The handle is comfortable, and the operation is easy and natural, reducing the fatigue caused by long-term use and improving work efficiency;

[0021] In this utility model, the inclined cutter head design: The cutter head adopts an inclined design. This unique design makes it more convenient to exert force during the ring cutting operation. Users can apply force more easily, improving the cutting efficiency and at the same time reducing the operation difficulty and labor intensity. Description of the Drawings
