Description

Technical Field

[0001] This invention relates to the field of fruit and vegetable processing machinery, and in particular to a vertical sugarcane peeling machine, which can also be used for peeling oblong fruits and vegetables such as loofah, gourd, yam, lettuce shoots, and cucumber. Background Technology

[0002] Sugarcane (fruit sugarcane) is rich in nutrients and has a delicious taste, making it a popular food. When eating sugarcane, it usually needs to be peeled beforehand, a task typically done by fruit shops. The conventional (and most basic and common) peeling method involves manually slicing the sugarcane back and forth repeatedly with a sugarcane peeler. This process is time-consuming, laborious, and unhygienic, causing considerable distress to fruit shop owners. There is an urgent need for a sugarcane peeling machine that offers excellent peeling results, stable performance, ease of operation, adaptability to different sugarcane lengths, thicknesses, and shapes, high speed, small footprint, easy transport, lightweight, low noise, and simple maintenance.

[0003] Most existing sugarcane peeling machines (including patents, literature, etc.) use a horizontal structure (i.e., sugarcane is placed horizontally and processed horizontally). The peeling principle mainly includes planing with blades and turning with milling cutters. The horizontal structure has the following main drawbacks: 1. Sugarcane is very brittle after peeling and is prone to breakage when placed horizontally; 2. Horizontal placement makes it difficult for sugarcane peel, sugarcane scraps, and sugarcane residue to detach from the blades in time, easily getting stuck on the blades and related mechanisms, resulting in unstable and incomplete peeling; 3. With the sugarcane placed horizontally, sugarcane scraps, sugarcane residue, sugarcane peel, and dirt, dust, or other adhering substances generated during cutting will fall freely or splash (generated by milling cutters), remaining on the peeled sugarcane. At the same time, the peeled part will also come into contact with the support or clamping parts at the exit end, resulting in poor cleanliness and hygiene. Some machines use rotating brushes for cleaning, but this cannot truly clean the sugarcane and can also cause secondary pollution; 4. Large footprint. The horizontal structure machine itself occupies a larger area (compared to the vertical structure of this invention), plus 1.5 meters to 3 meters of floor space. 5. For horizontal machines that use rollers to horizontally feed sugarcane, the latter half still needs to be pulled by hand, which is unhygienic, inconvenient, and prone to breakage. 6. For horizontal machines that use horizontal segmented feeding, alternating clamping at the front and rear ends, and multi-blade push-pull planing, thin sugarcane is prone to breakage and jamming. The contact claws at the outlet end also require hand handling, which is inconvenient and unhygienic. 7. The mechanical structure is too complex and heavy, making it difficult to move, maintain, and repair. 8. Most of them use purely mechanical operation and control, resulting in significant noise during operation. 9. Due to their low profile, horizontal machines require bending over for operation, making them inconvenient to use.

[0004] Two patents for vertical sugarcane peeling machines were found through patent search. One is patent CN212368288U, which focuses on a design where the clamping part is at the bottom and the cutting mechanism is located in the lower middle. Theoretical analysis and experiments have shown that this layout cannot perform continuous and reliable cutting. The reason is that when the blade cuts the sugarcane from top to bottom, the sugarcane is subjected to axial pressure (especially thinner or more curved sugarcane), which easily leads to instability, causing the sugarcane to break, bend, and resulting in peeling failure or operation stoppage. The other is patent CN107156873A (which was rejected). The core of this patent is the mechanism driven by the first drive motor, which is essentially a cam gap divider. Summary of the Invention

[0005] As described in the background section, to better solve the technical problem of replacing manual sugarcane peeling with machines, this invention provides a novel technical solution. The term "vertical" refers to processing the sugarcane upright. Its basic characteristics are a vertical structure, downward cutting with a return stroke, meaning the sugarcane is held upright with its upper end fixed and its lower end naturally vertical. Two or more blades approach the outer diameter of the sugarcane and peel from top to bottom. After reaching the lower end, the blades move away from the outer diameter and return upwards, causing the sugarcane peel to fall naturally from the outside of the sugarcane, away from the peeled portion. During cutting, the sugarcane is subjected to axial tensile force, preventing breakage. For curved sugarcane, the elastic deformation due to tension automatically straightens it, thus providing excellent peeling results even on curved sugarcane. The machine automatically adapts to the thickness and length of the sugarcane. The mechanical parts adopt a modular design, resulting in fewer mechanical components and a lighter weight.

[0006] This technical solution includes: a chassis, a frame, and a top. The chassis is at the bottom, the frame is vertically arranged above the chassis, and the top is at the top of the frame. The top has a clamping cylinder with a rocker arm, T-shaped wedge slider, or wedge slider clamping mechanism. The rocker arm clamping mechanism is preferred due to its small size. This clamping mechanism is used to hold the upper end of the sugarcane. The clamping cylinder is connected to an indexing motor via a belt, chain, gear, rack, or coaxial connection, allowing the sugarcane to rotate in an indexing motion. The frame has rolling guides connected to a slide table. The slide table is connected to a lifting motor via a belt, chain, rack, or ball screw, driving the lifting motor to move the slide table up and down. The slide table can move within the entire stroke range of the rolling guides. A toothed belt drive is preferred due to its light weight, anti-slip properties, and low noise. There are two or more cutting tools on the slide, that is, one or more cutting tools are installed in the same cross section perpendicular to the sugarcane axis. Cutting tools can be installed in different cross sections with staggered positions, but the total number of cutting tools should be two or more. The optimal structure is one with two cutting tools arranged symmetrically on the slide. The cutting tool includes a tool body, a rotary tool body, a yaw tool body, or a rotary-yaw tool body. The tool is mounted on a slide table or on a slider with guide rails and a slider on the slide table. The tool or slider is connected to a tool motor, cylinder, hydraulic cylinder, or electromagnet. The above three sentences refer to five possible layouts, movements, and combinations of the tool on the slide table. These five schemes can produce similar functions. The first scheme is: the rotary tool body is directly arranged on the slide table at a certain angle, and the rotary tool body is connected to a tool motor, cylinder, hydraulic cylinder, or electromagnet; the tool body can actively swing and passively swing. The second scheme is: the rotary-yaw tool body is directly arranged on the slide table at a certain angle, and the rotary-yaw tool body is connected to a tool motor, cylinder, hydraulic cylinder, or electromagnet; the tool body can actively swing and passively swing. The third scheme is: the slide table has guide rails and a slider, and the rotary tool body is mounted at a certain angle... The first option is to mount the tool on a slider, with the number of sliders matching the number of tools. The sliders connect to the tool motor, cylinder, hydraulic cylinder, or electromagnet, allowing the tool to move actively and swing passively. This layout is the most convenient and optimal. The second option is to have a guide rail and sliders on the slide table. The oscillating tool is mounted on the sliders at a certain angle, with the number of sliders matching the number of tools. The sliders connect to the tool motor, cylinder, hydraulic cylinder, or electromagnet, allowing the tool to move actively and swing passively. The third option is to have a guide rail and sliders on the slide table. Each tool has two sliders connected by a spring. The tool is mounted on one slider at a certain angle. This tool usually refers to the tool body, but it can also be a rotary tool body, an oscillating tool body, or a rotary-oscillating tool body. The other slider, which does not have the tool mounted on it, connects to the tool motor, cylinder, hydraulic cylinder, or electromagnet, allowing the tool to move actively and passively.

[0007] The clamping cylinder has a rocker arm type, T-shaped wedge slider type, or wedge slider type clamping mechanism. The clamping mechanism includes a rocker arm, a T-shaped wedge slider, or a wedge slider component. It also includes a sliding body and two or more jaws. The sliding body can be a groove-shaped sliding body, a wedge-shaped sliding body, a T-shaped wedge sliding body, or a cylindrical sliding body, and can be installed inside or outside the clamping cylinder. The movement of the jaws in the rocker arm type clamping mechanism can be parallel or fulcrum-opening / closing. If it is fulcrum-opening / closing, the rocker arm component and the jaws can be integrated. Installing three jaws is optimal for self-centering, and they should be evenly or symmetrically arranged at the same cross-section along the axis of the clamping cylinder.

[0008] There are three drive schemes for the clamping mechanism claws at the clamping cylinder. The first scheme involves a sliding body installed inside the clamping cylinder, connected to a screw or lead screw, which in turn connects to a nut. The nut is connected to the clamping motor via a belt, chain, gear, or coaxial connection, or the nut is placed on the clamping motor rotor. This scheme is the most compact and optimal. Alternatively, the positions of the screw or lead screw and the nut connecting the sliding body and the clamping motor can be interchanged, with the same working principle. The second scheme involves the sliding body installed inside the clamping cylinder, connected to a cylinder, hydraulic cylinder, or electromagnet. The third scheme involves the sliding body installed outside the clamping cylinder. In the first and second schemes, two sets of drive mechanisms are symmetrically installed on the outside of the clamping cylinder and connected to the sliding body. Alternatively, a large rocker arm based on a lever principle can be added outside the slide, reducing the number of drive mechanisms to only one set. The clamping principle of the clamping mechanism at the clamping cylinder is to use the linear displacement generated by the screw, lead screw or nut driven by the clamping motor, or the telescopic displacement generated by the cylinder, oil cylinder or electromagnet to push and pull the slide body or to push and pull the slide body up and down through the large rocker arm. Then, through the lever or wedge principle, the rocker arm, T-shaped wedge slider or wedge slider component moves, thereby driving the chuck to clamp and release the sugarcane.

[0009] The frame has one or more rolling guide rails, arranged parallel to the length of the frame side wall, installed on the frame side wall, integrally formed with the frame or manufactured as one piece with the frame, including double-axis core roller guide rails, ball guide rails, linear bearings or guide rails composed of rolling bearing assemblies, with double-axis core roller guide rails being the best for high-speed and quiet operation.

[0010] There are two design options for the knife body: 1. The knife body includes a blade and a blade holder, with the blade mounted on the blade holder. This design is optimal for easy resharpening and adjustment. 2. The blade and blade holder are manufactured as a single piece or integrally formed. A limiting post is located on the lower side of the knife body. Adjusting the position of the limiting post relative to the blade edge allows for initial determination of the sugarcane peeling thickness. The blade edge shape can be straight, polygonal, or arc-shaped. A straight or polygonal blade edge results in a regular polygonal peel, while an arc-shaped blade edge results in a near-circular peel.

[0011] Some designs incorporate a pivot in the cutter body, termed a pivot cutter body, which has a rotatable pivot. The pivot cutter body is equipped with springs, including torsion springs, tension springs, or compression springs, to generate a preloaded rotational torque by causing the cutter body to oscillate around the pivot. The cutter body can passively oscillate around the pivot.

[0012] Some designs incorporate a blade body that can oscillate, known as an oscillating blade body. The blade body is connected to the base plate via one or more springs, including compression springs, leaf springs, torsion springs, tension springs, and coil springs. When force is applied to one end of the blade body, because the force point is at the edge, the blade body can oscillate relative to the base plate.

[0013] Some designs feature a pivot on the base plate of the oscillating cutter body, known as a pivot oscillating cutter body, which allows the oscillating cutter body to oscillate around the pivot on the base plate.

[0014] In some designs, the slide has guide rails and sliders, which are arranged laterally, obliquely, or arc-shaped. The sliders can move along lateral, oblique, or arc-shaped trajectories, allowing the cutter on the slider to approach or leave the sugarcane in a non-axial direction.

[0015] Optionally, a retaining ring is provided above the cutter, that is, a retaining ring is installed above the uppermost cutter on the slide to limit the swing range of the sugarcane.

[0016] Optionally, the side of the blade from which the sugarcane peel exits has a baffle or a peel-cutting blade. The peel-cutting blade has a shearing or gate-cutting structure and is connected to a peel-cutting motor, cylinder, hydraulic cylinder, or electromagnet. There are two ways to reduce the area of ​​sugarcane peel on the ground: 1. A baffle on the side of the blade from which the peel exits changes the direction of the peel exit, forcing it to bend downwards immediately. 2. A peel-cutting blade is installed on the side of the blade from which the peel exits. This blade has a shearing or gate-cutting structure, and its operation is driven by a peel-cutting motor, cylinder, hydraulic cylinder, or electromagnet. The option of installing a peel-cutting blade on the blade results in a smaller area of ​​sugarcane peel on the ground, making collection easier.

[0017] Optionally, a handle is installed on the outside of the frame, and casters are installed under the chassis for easy handling and movement of the machine. The frame, slide, slider, and clamping cylinder are made of aluminum alloy to reduce the weight of the machine. A collection box is located on or around the chassis to collect sugarcane peel, bagasse, and sugarcane scraps, keeping the environment clean.

[0018] The indexing motor, lifting motor, clamping motor, tool motor, and peeling motor described in the technical solution include servo motors, stepper motors, synchronous motors, DC motors, or AC motors and their corresponding geared motors. Using a servo motor for the lifting motor can improve the lifting speed; using a servo motor or stepper motor for the indexing motor can improve the indexing accuracy; and using a servo motor or stepper motor for the tool motor can improve the movement speed and precisely control the peeling thickness.

[0019] In this technical solution, a position sensor or displacement sensor can be installed to detect the outer diameter and length of the sugarcane. Adjusting the position or displacement sensor, or adjusting relevant parameters in the control device, allows for fine-tuning of the sugarcane's peeling thickness.

[0020] In the technical solution, priority is given to using control devices with microcomputer control systems, which facilitates intelligent operation and convenient maintenance.

[0021] Beneficial effects: Based on theoretical analysis and verification through implementation examples, this machine solution has the following advantages: 1. Thorough peeling of sugarcane, leaving no defects; 2. Uniform, stable, and consistent peeling thickness, with adjustable thickness; 3. Beautiful appearance of peeled sugarcane, good straightness in the length direction, and an outer diameter that is a regular polygon or close to a circle; 4. Hygienic and clean sugarcane after peeling, leaving no sugarcane scraps, residue, peel, dirt, dust, or other impurities, and eliminating hand contact with sugarcane during processing; 5. Stable performance and reliable operation, with smooth peeling that keeps the peel away from already peeled sugarcane, leaving no sugarcane scraps or residue on the blade; 6. Fast, stable, and reliable clamping and releasing of the sugarcane clamping part, with a clamping part length of less than 5 cm, resulting in high sugarcane utilization; 7. High sugarcane peeling efficiency, with high sliding speed... It can reach speeds of over 1 meter per second. If two blades are installed and the peeling is set to 5 times, a 1.5-meter-long sugarcane can be peeled in less than 18 seconds; 8. It automatically adapts to sugarcane of various outer diameters, lengths, and shapes without adjustment, and still has a good peeling effect on curved sugarcane; 9. The sugarcane will not break; 10. It is lightweight, weighing less than 45 kilograms, making it easy to transport; 11. It has a small footprint, with the chassis dimensions designed to be less than 50cm*40cm, meaning the machine's floor area is less than 0.2 square meters, and the sugarcane peel floor area calculated based on the symmetrical arrangement of two blades is less than 0.4 square meters; 12. The noise level is less than 70 decibels, a low-noise design that does not affect environmental harmony; 13. The machine features a modular design and an intelligent control scheme, making it easy to operate and maintain. Attached Figure Description

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.

[0052] Example 1

[0053] A vertical sugarcane peeling machine, such as Figure 1 , Figure 11 and Figure 15-17 As shown, it includes: a chassis 1, a frame 2, and a top 3. The chassis 1 is at the bottom, the frame 2 is arranged vertically above the chassis 1, and the top 3 is at the top of the frame 2. The top 3 has a clamping cylinder 4, and the clamping cylinder 4 has a rocker arm type, T-shaped wedge slider type, or wedge slider type clamping mechanism 5. The clamping cylinder 4 is connected to an indexing motor 6 via a belt, chain, gear, rack, or coaxial connection. The frame 2 has a rolling guide rail 7, which is connected to a slide table 8. The slide table 8 is connected to a lifting motor 10 via a belt 9, chain, rack, or ball screw. The slide table 8 has two or more cutting tools 11. The cutting tool 11 includes a cutting tool body 1101, a rotating shaft cutting tool body 1102, a swaying cutting tool body 1103, or a rotating shaft swaying cutting tool body 1104. The cutting tool 11 is mounted on the slide table 8 or on a slider 13 on the slide table 8 with a guide rail 12 and a slider 13. The cutting tool 11 or the slider 8 is connected to a cutting tool motor 14, a cylinder, a hydraulic cylinder, or an electromagnet.

[0054] The working steps and process are as follows: 1. Hold the sugarcane 22 vertically and place its upper end into the clamping cylinder 4. Operate the clamping switch on the control panel to clamp the sugarcane 22. 2. Press the run button on the control panel. The machine will start running automatically. The workflow is as follows: Step 1: The cutter 11 on the slide table 8 quickly moves towards the axis of the sugarcane 22. Through the detection of the position or displacement sensor or the use of the outer diameter parameter set in the control device, the cutter 11 makes proper contact with the outer diameter of the sugarcane 22. Step 2: The slide table 8 quickly descends to peel the sugarcane. Through the detection of the position or displacement sensor or the use of the length parameter set in the control device, when the slide table 8 reaches the end of the sugarcane 22, the slide table 8 stops descending. Step 3: The cutter 11 on the slide table 8... The machine begins to move away from the axis of the sugarcane 22. The clamping cylinder 4 rotates one division value, and the slide 8 begins to move rapidly upwards. The synchronized movement of these three elements effectively removes sugarcane scraps and residue from the blade. This is because the sugarcane 22 is not perfectly straight, nor is it perfectly perpendicular during clamping. During the indexing rotation, the sugarcane 22 will sway, causing its outer diameter to slightly touch the sugarcane scraps and residue attached to the rising blade, causing them to detach and fall off. Fourth step: The slide 8 reaches its highest point, the blade 11 reaches a position away from the axis of the sugarcane 22, and the clamping cylinder 4 rotates one division value. This completes one peeling cycle. Continuously repeating this cycle a set number of times will complete the peeling of one sugarcane 22, and the machine will automatically stop. The number of peeling cycles can be set in the control device. Third, release the switch on the control panel and remove the sugarcane 22.

[0055] Example 2

[0056] Based on Example 1, such as Figure 1 , Figure 2-9 As shown, the clamping cylinder 4 has a rocker arm type, a T-shaped wedge slider type, or a wedge slider type clamping mechanism 5. The clamping mechanism 5 has a rocker arm 501, a T-shaped wedge slider 502, or a wedge slider 503. The clamping mechanism 5 has a slider 504 and two or more jaws 505. The slider 504 includes a groove-shaped slider 5041, a wedge-shaped slider 5042, a T-shaped wedge slider 5043, or a cylindrical slider 5044. The slider 504 can be installed on the inner or outer side of the clamping cylinder 4. Installing three jaws 505 is optimal for self-centering, and they are evenly or symmetrically arranged at the same cross-section as the axis of the clamping cylinder 4.

[0057] The clamping cylinder 4 has a rocker arm type, a T-shaped wedge slider type, or a wedge slider type clamping mechanism 5, referring to three design options. The first option is a rocker arm type clamping mechanism 5, where one end of the rocker arm 501 is connected to the horizontal slider 506 on the lower side of the clamping cylinder 4, and the other end is connected to the groove-shaped slider 5041 or the wedge-shaped slider 5042. The jaw 505 is mounted on the horizontal slider 506, which is a parallel jaw 505. If it is a fulcrum opening and closing jaw 505, the horizontal slider 506 can be omitted, and the rocker arm 501 and the jaw 505 can be integrated. This option is the preferred specific design. Implementation methods: Second option: T-shaped wedge slider clamping mechanism 5, with a horizontal slider 502 on the lower side of the clamping cylinder 4 featuring a T-shaped protrusion or grooved wedge. This horizontal slider 502 is connected to a T-shaped grooved or protruding wedge-shaped slide body 5043. A jaw 505 is mounted on the horizontal slider 502, and is a parallel jaw 505. Third option: Wedge slider clamping mechanism 5, with a horizontal slider 503 containing a wedge on the lower side of the clamping cylinder 4. This horizontal slider 503 is connected to a cylindrical slide body 5044. A jaw 505 is mounted on the horizontal slider 503, and is a parallel jaw 505. The above illustration shows an example where the slide body 504 is inside the clamping cylinder 4. If the slide body 504 is outside the clamping cylinder 4, the connection parts of the rocker arm 501, T-shaped wedge slider 502, or wedge slider 503 to the slide body 504 should also be designed on the outside, following the same principle.

[0058] There are three driving schemes for the clamping mechanism 5 jaws 505 at the clamping cylinder 4. The first scheme involves a sliding body 504 installed inside the clamping cylinder 4, connected to a screw or lead screw 15, which in turn connects to a nut 16. The nut 16 is connected to a clamping motor 17 via a belt, chain, gear, or coaxial connection, or the nut 16 is placed on the rotor of the clamping motor 17. This is the preferred embodiment. Alternatively, the positions of the screw or lead screw 15 and the nut 16 connecting the sliding body 504 and the clamping motor 17 can be interchanged. The working principle is the same; the second option: the slide body 504 is installed inside the clamping cylinder 4, and the slide body 504 is connected to the cylinder, oil cylinder or electromagnet 18; the third option: the slide body 504 is installed outside the clamping cylinder 4, then the drive mechanism 18 or 15, 16 and 17 in the first and second options above are two sets symmetrically installed on the outside of the clamping cylinder 4 and connected to the slide body 504. Alternatively, a large rocker arm 507 based on the lever principle can be added outside the slide body 504, so only one set of drive mechanism 18 or 15, 16 and 17 is needed.

[0059] The clamping principle of the clamping mechanism 5 at the clamping cylinder 4 is to use the linear displacement generated by the screw, lead screw 15 or nut 16 driven by the clamping motor 17, or the telescopic displacement generated by the cylinder, oil cylinder or electromagnet 18, to push and pull the slide body 504 or to push and pull the slide body 504 up and down through the large rocker arm 507. Then, through the lever or wedge principle, the rocker arm 501, T-shaped wedge slider 502 or wedge slider 503 components move, thereby driving the chuck 505 to clamp and release the sugarcane 22.

[0060] Example 3

[0061] Based on Example 1, such as Figure 1 As shown, the frame 2 has one or more rolling guide rails 7, which are arranged parallel to the length direction of the side wall of the frame 2. They are installed on the side wall of the frame 2, integrally formed with the frame 2, or made as one piece with the frame 2. They include double-axis core roller guide rails, ball guide rails, linear bearings, or guide rails composed of rolling bearing groups. The preferred embodiment is to use two sets of double-axis core roller guide rails.

[0063] Based on Example 1, such as Figure 1 As shown, the rolling guide rail 7 is connected to the slide table, and the slide table 8 is connected to the lifting motor 10 via a belt 9, chain, rack or ball screw. The preferred embodiment is to use a toothed belt drive 9.

[0064] The drive motor 10 enables the slide table 8 to move up and down, and the slide table 8 can move within the entire travel range of the rolling guide rail.

[0065] Example 5

[0066] Based on Example 1, such as Figure 1 , Figure 10 As shown, there are two or more cutting tools 11 on the slide table 8. One or more cutting tools 11 are installed in the same cross section perpendicular to the axis of the sugarcane 22. The cutting tools 11 can be installed in different cross sections with staggered positions, but the total number of cutting tools 11 should be two or more. The preferred embodiment is to use two cutting tools 11 on the slide table 8 and arrange them symmetrically.

[0067] Example 6

[0068] Based on Example 1, such as Figure 1 , Figure 11-17 As shown, the cutting tool 11 includes a tool body 1101, a rotating shaft tool body 1102, a yaw tool body 1103, or a rotating shaft yaw tool body 1104. There are four types of cutting tools 11.

[0069] The first type: the blade body 1101, has two options: 1. The blade body 1101 includes a blade 11011 and a blade holder 11012, with the blade 11011 mounted on the blade holder 11012. This is the preferred embodiment. 2. The blade 11011 and the blade holder 11012 are manufactured as a single piece or integrally formed. A limiting post 11013 is located on the lower side of the blade body 1101. The cutting edge shape of the blade body 1101 includes a straight line 110111, a polygon 110112, or an arc 110113.

[0070] Adjusting the positional relationship between the limiting post 11013 and the cutting edge of the blade 1101 can initially determine the peeling thickness of the sugarcane 22. If the cutting edge is straight (110111) or polygonal (110112), the peeled sugarcane 22 will have a regular polygonal shape; if the cutting edge is arc-shaped (110113), the peeled sugarcane 22 will have a shape close to a circle.

[0071] The second type: the rotating shaft cutter body 1102, based on the first type, the cutter body 1101 contains a rotating shaft 1105, that is, the cutter body 1101 has a rotating shaft 1105 that can swing and rotate, and the rotating shaft cutter body 1102 is equipped with a spring, including a torsion spring, a tension spring or a compression spring. This type is the preferred embodiment.

[0072] The spring is used to generate a preloaded rotational torque so that the blade body 1101 can swing around the rotating shaft 1105. The blade body 1101 can passively swing around the rotating shaft 1105.

[0073] The third type: the oscillating blade body 1103, based on the first type, the blade body 1101 is connected to the base plate 1107 by one or more springs 1106, including compression springs, leaf springs, torsion springs, tension springs and coil springs.

[0074] When one end of the blade 1101 is subjected to force, because the point of force application is at the edge, the blade 1101 can produce a passive yaw motion relative to the base plate 1107.

[0075] The fourth type: the pivot-shaft tilting cutter body 1104. Based on the third type, the pivot-shaft 1105 is located on the base plate 1107 of the tilting cutter body 1103.

[0076] The oscillating cutter body 1103 can oscillate around the pivot 1105 on the base plate 1107.

[0077] Example 7

[0078] Based on Example 1, such as Figure 1 , Figure 18-20 As shown, in some design schemes, the slide table 8 has guide rails 12 and sliders 13. The slide table 8 has guide rails and sliders 13 arranged horizontally 1201, obliquely 1202 or arc 1203.

[0079] The slider 13 can move along a horizontal 1201, an oblique 1202, or an arc 1203 trajectory, so that the cutter 11 on the slider 13 approaches or moves away from the outer diameter of the sugarcane 22 in a non-axial direction.

[0080] Example 8

[0081] Based on Examples 1, 6, and 7, such as Figure 1 , Figure 11 and Figure 15-25 As shown, the tool 11 is mounted on the slide table 8 or on the slide table 8 with a guide rail 12 and a slider 13. The tool 11 or the slider 13 is connected to the tool motor 14, cylinder, oil cylinder or electromagnet. This means that there are five schemes for the layout, movement and combination of the tool 11 on the slide table 8. These five schemes can produce similar functions.

[0082] The first option is to place the rotary cutter body 1102 directly on the slide table 8 at a certain angle, and connect the rotary cutter body 1102 to the tool motor 14 or to a cylinder, hydraulic cylinder or electromagnet.

[0083] When using a tool motor 14, the rotating shaft 1102 of the tool body 1102 is coaxially connected to the rotating shaft 1105, or connected to the rotating shaft 1105 of the tool body 1102 via gears, racks, chains, or belts, causing the tool body 1102 to actively oscillate around the rotating shaft 1105. When using a cylinder, hydraulic cylinder, or electromagnet, the telescopic displacement generated by the above components is used to push and pull the rotating shaft 1102, causing it to actively oscillate around the rotating shaft 1105.

[0084] The rotating blade 1102 can swing around the rotating shaft 1105 actively and passively. Active swinging means that when the slide table 8 is going down to peel, the rotating blade 1102 swings to contact the sugarcane 22, and when it is going up, the rotating blade 1102 swings away from the sugarcane 22. The passive swinging function is that there is a spring on the rotating blade 1102, which gives the rotating blade 1102 a pre-pressure applied to the outer diameter of the sugarcane 22 to adapt to the different thicknesses and sugarcane nodes of the same sugarcane 22.

[0085] The second option is: the pivot tilting tool body 1104 is directly arranged on the slide table 8 at a certain angle, and the pivot tilting tool body 1104 is connected to the tool motor 14 or to a cylinder, oil cylinder or electromagnet.

[0086] When using a tool motor 14, the rotating shaft 1105 of the rotating shaft oscillating tool body 1104 is coaxially connected, or connected via gears, racks, chains, or belts, causing the rotating shaft oscillating tool body 1104 to actively oscillate around the rotating shaft 1105. When using a cylinder, hydraulic cylinder, or electromagnet, the extension and retraction displacement generated by these components is used to push and pull the base plate 1107 of the rotating shaft oscillating tool body 1104, causing it to actively oscillate around the rotating shaft 1105.

[0087] The swivel blade 1104 can actively oscillate around the swivel 1105 on the base plate 1107 and passively oscillate relative to the base plate 1107. Active oscillation means that when the slide table 8 is going down to peel, the swivel blade 1104 oscillates to contact the sugarcane 22, and when it is going up, the swivel blade 1104 oscillates away from the sugarcane 22. Because the swivel blade 1104 has a spring 1106 and is subjected to force at one end, the swivel blade 1104 is passively oscillated. The passive oscillation is to give the swivel blade 1104 a pre-pressure applied to the outer diameter of the sugarcane 22 to accommodate the different thicknesses and nodes of the same sugarcane 22.

[0088] The third option is: the slide table 8 has a guide rail 12 and a slider 13, the rotary shaft cutter body 1102 is installed on the slider 13 at a certain angle, the number of sliders 13 is the same as the number of cutters 11, and the sliders 13 are connected to the cutter motor 14, cylinder, oil cylinder or electromagnet. This option is the preferred specific implementation.

[0089] The slider 13 is connected to the tool motor 14 via a belt, chain, rack, gear or lead screw, or the slider 13 is connected to a cylinder, oil cylinder or electromagnet, so that the slider 13 and the rotating shaft tool body 1102 generate active movement.

[0090] The slider 13 and the rotating blade 1102 can move actively on the guide rail 12 of the slide table 8. The rotating blade 1102 can passively swing around the rotating shaft 1105. When the slide table 8 is peeling downwards, the slider 13 moves actively to make the rotating blade 1102 contact the sugarcane 22. When it is moving upwards, the slider 13 moves actively to make the rotating blade 1102 leave the sugarcane 22. Because the rotating blade 1102 has a spring, it can passively swing around the rotating shaft 1105. The passive swinging function is to give the rotating blade 1102 a pre-pressure applied to the outer diameter of the sugarcane 22 to adapt to the different thicknesses and sugarcane nodes of the same sugarcane 22.

[0091] The fourth option is: the slide table 8 has a guide rail 12 and a slider 13, the tilting cutter body 1103 is installed on the slider 13 at a certain angle, the number of sliders 13 is the same as the number of cutters 11, and the slider 13 is connected to the cutter motor 14, cylinder, oil cylinder or electromagnet.

[0092] The slider 13 is connected to the tool motor 14 via a belt, chain, rack, gear, or lead screw, or the slider 13 is connected to a cylinder, hydraulic cylinder, or electromagnet, so that the slider 13 and the oscillating tool body 1103 generate active movement.

[0093] The slider 13 and the swaying blade 1103 can move actively on the guide rail 12 of the slide table 8. The swaying blade 1103 can passively sway relative to the base plate 1107. When the slide table 8 is peeling downwards, the slider 13 moves actively to make the swaying blade 1103 contact the sugarcane 22. When it is moving upwards, the slider 13 moves actively to make the swaying blade 1103 leave the sugarcane 22. The swaying blade 1103 is passively swaying because it has a spring 1106 and is subjected to force at one end. The passive swaying is to give the swaying blade 1103 a pre-pressure applied to the outer diameter of the sugarcane 22 to accommodate the different thicknesses and nodes of the same sugarcane 22.

[0094] The fifth option is: the slide table 8 has a guide rail 12 and a slider 13. A tool 11 has two sliders 13. The two sliders 13 are connected by a spring 1301. The tool 11 is mounted on a slider 13 at a certain angle. The tool 11 usually refers to the tool body 1101, but it can also be a rotary tool body 1102, a yaw tool body 1103, or a rotary yaw tool body 1104.

[0095] Another slider 13 without the tool 11 is connected to the tool motor 14 via a belt, chain, rack, gear or lead screw, or the slider 13 without the tool 11 is connected to a cylinder, hydraulic cylinder or electromagnet, so that the two sliders 13 and the tool 11 can generate active movement.

[0096] The two sliders 13 have the same movement trajectory. The slider 13 without the blade 11 moves actively, while the slider 13 with the blade 11 moves passively and follows. When the slide table 8 is peeling downwards, the slider 13 without the blade 11 moves actively, and the slider 13 with the blade 11 moves following, causing the blade 1101 to contact the sugarcane 22. When the slide table 8 is moving upwards, the slider 13 without the blade 11 moves actively, and the slider 13 with the blade 11 moves following, causing the blade 1101 to leave the sugarcane 22. The two sliders 13 are connected by the spring 1303. When the slider 13 with the blade 11 is subjected to an external force, it has a certain relative displacement change relative to the other slider 13. The slider 13 with the blade 11 moves passively, so that the blade 1101 has a pre-pressure applied to the outer diameter of the sugarcane 22 to accommodate the different thicknesses and nodes of the same sugarcane 22.

[0097] Example 9

[0098] Based on Example 1, such as Figure 1 As shown, there is a material surrounding ring 19 above the cutter 11, that is, the material surrounding ring 19 is installed above the uppermost cutter 11 on the slide table 8.

[0099] Used to limit the swing range of sugarcane 22.

[0100] Example 10

[0101] Based on Example 6, such as Figure 26-28As shown, some designs have a baffle 20 or a peeling knife 21 on the side where the knife 11 comes out of the peel, which means there are two ways to reduce the area of ​​sugarcane peel on the ground.

[0102] 1. The side of the knife 11 that exposes the peel has a baffle 20 to block the sugarcane peel.

[0103] After the sugarcane peel comes out of the blade 11, the direction of peeling is changed, and the baffle 20 forces the sugarcane peel to immediately bend downwards.

[0104] 2. A peeling knife 21 for cutting sugarcane peel is installed on the side of the blade 11 where the peel is exposed. The peeling knife 11 is a shearing or gate cutting structure. The action of the peeling knife 21 is driven by a peeling motor, cylinder, oil cylinder or electromagnet.

[0105] On the side of the blade 11 where the peel is exposed, there is a fixed peeling blade 21, referred to as the fixed blade 2101, and another movable peeling blade 21, referred to as the movable blade 2102. When using a shearing method, the movable blade 2102 and the fixed blade 2101 share a common axis 2103, and the movable blade 2102 rotates around the common axis 2103 to cut the sugarcane peel. When using a gate cutting method, the movable blade 2102 and the fixed blade 2101 are arranged parallel to each other, and the movable blade 2102 moves in the direction perpendicular to the cutting edge to gate cut the sugarcane peel.

[0106] When using a shearing motor as the drive source, for the shearing scheme, the moving blade 2102 is connected to the shearing motor via gears, belts, chains, racks, or coaxial connections. The moving blade 2102 can continuously rotate or oscillate to shear using a common shaft. For the gate cutting scheme, the moving blade 2102 is connected to the shearing motor via a cam mechanism, linkage mechanism, rocker arm mechanism, or gear and rack mechanism, causing the moving blade 2102 to move back and forth for gate cutting. When using a cylinder, hydraulic cylinder, or electromagnet as the drive source, their extension and retraction displacement is used to drive the moving blade to perform shearing or gate cutting.

[0107] During the peeling process, the slide table 8 and the blade 11 move downwards, causing the peeling blade 21 to move at a certain frequency, so that the sugarcane peel is cut into multiple small sections.
