Description

Technical Field

[0001] This invention relates to the field of sugarcane processing machinery, and more particularly to a vertical sugarcane peeling machine. Background Technology

[0002] People usually need to peel sugarcane before eating it. Conventional peeling involves using only one peeler along the same peeling path. This works well for regular and tender sugarcane. However, because sugarcane varies in size, some are hard and some are tender, some are thick and some are thin, some have nodes and teeth, and some are curved, sometimes the peeling is not thorough when using only one peeler along the same peeling path.

[0003] The patented technology in this application is a technological upgrade of a vertical sugarcane peeling machine with patent numbers 2023211360221 and 2023105326410. Summary of the Invention

[0004] As described in the background art, this paper addresses the problem that sometimes the peeling of sugarcane is not thorough when using only one peeling knife along the same peeling path.

[0005] This technical solution includes: a first cutting tool, a second cutting tool, a second cutting tool limiting post, a cutting tool movement mechanism, and a base plate. The second cutting tool limiting post is fixedly installed on the lower side of the second cutting tool and is used to control the peeling thickness. The cutting edges of the first and second cutting tools are parallel. The first and second cutting tools are mounted on the base plate via the cutting tool movement mechanism, which is equipped with a spring. The movement of the first and second cutting tools relative to the base plate is driven by the spring. When not peeling, both the first and second cutting tools are located away from the base plate. The cutting tool movement mechanism of the first cutting tool is a guide rail type or a parallel four-bar type, allowing the first cutting tool to move linearly or in a parallel four-bar motion relative to the base plate. The cutting tool movement mechanism of the second cutting tool is a guide rail type, a parallel four-bar type, or a rocker arm type, allowing the second cutting tool to move linearly, in a parallel four-bar motion, or in a swinging motion relative to the base plate. The cutting edge of the first cutter, near the outer diameter of the sugarcane, is always parallel to the sugarcane axis. The cutting edge of the second cutter, near the outer diameter of the sugarcane, is at an angle to the sugarcane axis. During peeling, the base plate is moved so that the cutting edges of the first and second cutters of this vertical sugarcane peeling knife device contact the outer diameter of the sugarcane and move downwards along the sugarcane axis. Alternatively, the vertical sugarcane peeling knife device can be fixed so that the sugarcane moves. Because the cutting edge of the first cutter, near the outer diameter of the sugarcane, is always parallel to the sugarcane axis, it can only remove the protruding sugarcane nodes, teeth, and outwardly curved protrusions on the outer surface of the sugarcane along the movement path along the sugarcane axis. Because the cutting edge of the second cutter, near the outer diameter of the sugarcane, is at an angle to the sugarcane axis, it is used to remove all the sugarcane peel along the movement path along the sugarcane axis. This vertical sugarcane peeling knife device can be arranged in one or more parts radially along the sugarcane axis.

[0006] Beneficial effects: Based on theoretical analysis and verification through implementation examples, this solution has the following advantages: 1. It can peel irregular, hard, and curved sugarcane more comprehensively and thoroughly without the need for manual trimming; 2. The peeling thickness of the sugarcane is more uniform, stable, and consistent; 3. The appearance of the peeled sugarcane is more beautiful and cleaner. Attached Figure Description

Detailed Implementation

[0016] The above solution will be further explained below with reference to specific embodiments. The following text description and accompanying drawings are all principle descriptions of the necessary technical features of the present invention. Those skilled in the art can make detailed designs or modifications based on this principle. As long as the principle is the same, it falls within the protection scope of the present invention patent. Example

[0017] A vertical sugarcane peeling knife device with two blades along the same peeling path, such as Figure 1As shown, the system includes: a first cutter 1, a second cutter 2, a second cutter limiting post 3, a cutter movement mechanism 4, and a base plate 5. The second cutter limiting post 3 is fixedly installed on the lower side of the second cutter 2 and is used to control the peeling thickness. The first cutting edge line 1001 of the first cutter 1 and the second cutting edge line 2001 of the second cutter 2 are parallel. The first cutter 1 and the second cutter 2 are mounted on the base plate 5 via the cutter movement mechanism 4, which is equipped with a spring. The movement of the first cutter 1 and the second cutter 2 relative to the base plate 5 is driven by the spring. When not peeling, both the first cutter 1 and the second cutter 2 are located away from the base plate 5. The first cutter 1 can move linearly or in parallel four-bar motion relative to the base plate 5, and the second cutter 2 can move linearly, oscillate, or in parallel four-bar motion relative to the base plate. The cutting edge plane 1002 of the first cutter 1 near the outer diameter of the sugarcane is parallel to the sugarcane axis, and the cutting edge plane 2002 of the second cutter 2 near the outer diameter of the sugarcane has an angle with the sugarcane axis. When peeling, the base plate 5 is moved so that the cutting edges of the first cutter 1 and the second cutter 2 of the vertical sugarcane peeling knife device contact the outer diameter of the sugarcane and move downward along the sugarcane axis, or conversely, the vertical sugarcane peeling knife device is fixed so that the sugarcane moves. Because the cutting edge plane 1002 of the first cutter near the outer diameter of the sugarcane is always parallel to the sugarcane axis, the first cutter 1 can only remove the protruding sugarcane nodes, teeth, and outwardly curved protruding parts on the outer surface of the sugarcane along the movement path of the sugarcane axis. Because the cutting edge plane 2002 of the second cutter near the outer diameter of the sugarcane has an angle with the sugarcane axis, the second cutter 2 is used to remove all the sugarcane peel along the movement path of the sugarcane axis. This vertical sugarcane peeling knife device can be arranged in one or more radial directions along the sugarcane axis, so that the sugarcane is subjected to balanced force in the radial direction and the processing efficiency is improved.

[0018] The working steps and process are as follows: 1. Move the base plate 5 so that the cutting edges of the first cutter 1 and the second cutter 2 contact the outer diameter of the sugarcane. 2. Move the vertical sugarcane peeling knife device downward along the sugarcane axis. At this time, because the cutting edge plane 1002 of the first cutter near the outer diameter of the sugarcane is always parallel to the sugarcane axis, it can only remove the protruding sugarcane nodes, teeth, and outwardly curved protruding parts on the outer surface of the sugarcane along the movement path of the sugarcane axis. Because the cutting edge plane 2002 of the second cutter near the outer diameter of the sugarcane is at an angle to the sugarcane axis, it is used to remove all the sugarcane peel along the movement path of the sugarcane axis. 3. When the vertical sugarcane peeling knife device reaches the end of the sugarcane, move the base plate 5 so that the cutting edges of the first cutter 1 and the second cutter 2 are away from the outer diameter of the sugarcane, and the peeling is completed.
