[0017] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0020] Please see Figures 1-4 This is the first embodiment of the present utility model. This embodiment provides an adjustable cutter head for a sugarcane cutter, including: First installation disk 1; Mounting component 2 is fixedly mounted on the back of the first mounting plate 1; Guide mechanism 5 is fixedly installed on the front of the two first mounting plates 1 and the mounting assembly 2. Tool holder 4 is fixedly installed at the bottom of guide mechanism 5; Adjustment structure 6 is fixedly installed inside the tool holder 4; Guide plate 3 is fixedly installed on the back of tool holder 4.

[0021] For example, the mounting assembly 2 includes a second mounting plate 22, with fixing rods 21 fixedly connected to all four sides of the second mounting plate 22. The left end of the fixing rods 21 is fixedly connected to the outer side of the first mounting plate 1, and a third mounting plate 23 is fixedly mounted on the right end of the fixing rods 21. The three first mounting plates 1, the second mounting plate 22, and the two sides inside the third mounting plate 23 are all provided with transverse guide rods 24 via transverse axes.

[0022] Furthermore, the guide block 51 is made of engineering plastic material, which is wear-resistant and lightweight, and is fixed to the front of the mounting plate by bolts; The top of the guide rod 52 is inserted into the through hole of the guide block 51 and can slide up and down. The bottom is welded to the top of the tool holder 4. It is a transmission rod that connects the guide block 51 and the tool holder 4. The spring 53 is made of manganese steel, which is elastic and durable and not easy to fatigue. It is sleeved on the surface of the guide rod 52 and located between the bottom of the guide block 51 and the top of the cutter holder 4. In its natural state, it is slightly compressed. It can drive the cutter holder 4 to adapt to the thickness of the sugarcane. When the sugarcane is thick, the spring is further compressed and when the sugarcane is thin, the spring rebounds.

[0023] For example, the guide mechanism 5 includes a guide block 51, the back of the guide block 51 is fixedly connected to the front of the first mounting plate 1, a guide rod 52 is provided inside the guide block 51, the bottom of the guide rod 52 is fixedly connected to the top of the tool holder 4, and a spring 53 is provided on the surface of the guide rod 52 and at the bottom of the guide block 51.

[0024] Furthermore, the material of the fixed blade 9 can be Teflon-plated to ensure that sugar does not stick, making it easier to clean, protecting the blade edge, and extending its lifespan; and the texture and the blade edge form a certain angle and depth, making it easier to remove chips and clean, forming a serrated shape.

[0025] For example, the adjusting structure 6 includes an adjusting bolt 61, which is located in a hole at the top of the tool holder 4. A threaded block 62 is fitted on the surface of the adjusting bolt 61 and at the bottom of the hole. The top of the threaded block 61 is fixedly connected to the inner wall of the tool holder 4.

[0026] Furthermore, the top of the tool holder 4 is welded to the guide rod 52, and the installation space of the adjustment structure 6 is reserved inside. The blade 9 is fixed at the bottom by bolts, and the guide plate 3 is welded to the back.

[0027] For example, a fixing inclined plate 7 is provided on the front of the tool holder 4, and a force-bearing rod 8 is provided at the bottom of the fixing inclined plate 7 and at the bottom inside the tool holder 4.

[0028] Furthermore, movable holes are provided at both ends of the inner side of the cutter holder 4. The two ends of the force rod 8 are inserted into the movable holes and can move freely. The range of motion is limited by the adjustment structure 6, thus enabling the entire structure to cut sugarcane of different thicknesses.

[0029] For example, the bottom of the knife holder 4 is fixed with a blade 9, which is in an inclined state, and the force rod 8 is used to limit the sugarcane during the peeling process.

[0030] Furthermore, the fixed blade 9 is fixed to the bottom of the blade holder 4 by 2-3 bolts. The inclined design at a 30-45 degree angle can reduce cutting resistance, prevent sugarcane fiber breakage, and allow for quick disassembly and replacement after wear.

[0031] During use, the sugarcane is guided into the machine: the sugarcane enters the transverse guide rod 21 through the transverse guide rod 24 on the right side of the machine, forming parallel channels on both sides of the first, second and third mounting plates, and moves to the left along the coaxial direction; at this time, the guide plate 3 on the back of the cutter holder 4 is in contact with the surface of the sugarcane, further calibrating the sugarcane to the cutting area below the cutter holder 4, avoiding sugarcane deviation or jamming.

[0032] The sugarcane is limited and fixed by a force-bearing rod to prevent it from moving around. When the sugarcane enters below the cutter holder 4, the force-bearing rod 8 inside the cutter holder 4 abuts against the surface of the sugarcane from the side. The inclination angle of the force-bearing rod 8 is adapted to the shape of the sugarcane, which limits the rotation and axial movement of the sugarcane during the cutting process, ensuring that the sugarcane always moves along a fixed path, thus providing a basis for stable peeling.

[0033] Subsequently, when the transverse guide rod 24 is moved by an external power device, the first mounting plate 1, the second mounting plate 22 and the third mounting plate 23 will move synchronously, thus causing all the structures installed on the three mounting plates to move laterally, thereby cutting the surface of the sugarcane.

[0034] If the sugarcane has a large diameter: the sugarcane squeezes the blade 9, which drives the blade holder 4 to move upward. The guide rod 52 slides upward along the through hole of the guide block 51, and the spring 53 is further compressed to counteract the squeezing force of the sugarcane, ensuring that the blade 9 always fits the surface of the sugarcane.

[0035] If the sugarcane is thinner: the spring 53 rebounds, pushing the blade holder 4 downward, the guide rod 52 slides down, and the blade 9 moves down accordingly, still maintaining contact with the sugarcane surface.

[0036] Because the nine guiding mechanisms 5 are arranged in three groups of 120-degree staggered and overall 360-degree staggered distribution, the nine fixed blades 9 can simultaneously cover the entire circumference of the sugarcane, achieving peeling without dead angles. Moreover, the inclined blade angle reduces cutting resistance and avoids waste of sugarcane pulp.

[0037] Precise blade adjustment: When it is necessary to adjust the peeling depth, such as to address the difference in peel thickness among different varieties of sugarcane, the adjusting bolt 61 on the top of the blade holder 4 can be manually rotated clockwise or counterclockwise. Since the threaded block 62 is fixed to the inner wall of the blade holder 4, the adjusting bolt 61 will move up and down along the threaded block 62, thereby driving the blade holder 4 to move up and down synchronously.

[0038] When the blade holder 4 moves, the distance between the fixed blade 9 at the bottom and the sugarcane changes accordingly. Moving it downwards peels the sugarcane more deeply, while moving it upwards peels it less deeply. After adjustment, no additional fixing is required, and the self-locking nature of the thread ensures that the blade position is stable.

[0039] In summary, the sugarcane is surrounded by nine guiding mechanisms 5, guide plates 3, and fixed blades 9 in all directions without any blind spots, thus enabling one-time peeling. The overall structure is simple and convenient, thereby reducing manufacturing and maintenance costs.

[0040] Please see Figure 5 This is the second embodiment of the present utility model.

[0041] For example, three guide mechanisms 5 are fixedly installed on the front of each of the three first mounting plates 1, the second mounting plate 22, and the third mounting plate 23. The total number of guide mechanisms 5 is nine. The nine guide mechanisms 5 are grouped into three groups, staggered by 120 degrees, and the three groups are staggered to perform a 360-degree peeling operation on the sugarcane.

[0042] Furthermore, the guide plate 3 is arc-shaped and its bottom is located at the bottom of the fixed blade 9, so that the sugarcane peel can be discharged outward through the guide plate 3 after the fixed blade has performed cutting work.

[0043] During use, the guide plate 3 can directionally move the cut sugarcane peel outwards, thus preventing it from getting stuck in the equipment and affecting subsequent work.

[0044] In summary, by adjusting structure 6, the cutting depth can be adjusted according to actual needs, thus reducing pulp loss and being compatible with sugarcane of different thicknesses and varieties.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
