Description

Technical Field

[0001] The invention relates to the technical field of lightweight building materials, and in particular to a bamboo aggregate production device. Background Art

[0002] In the field of lightweight building materials technology, with the increasing global awareness of environmental protection and the in-depth practice of the concept of sustainable development, finding and applying environmentally friendly and renewable resources has become an important development direction in this field. Bamboo, as a natural resource widely distributed around the world, has been increasingly valued in the field of building materials due to its characteristics of light weight, high strength, rapid growth, strong renewability and good carbon sequestration capacity. Bamboo aggregate concrete, as an innovative form of bamboo application, is a new type of composite material formed by processing bamboo into aggregates and combining it with concrete materials. This material not only inherits the characteristics of bamboo light weight, high strength and environmental protection, but also integrates the advantages of concrete such as durability, good compressive resistance and plasticity, thus showing a wide range of application prospects in many fields such as building structure, road paving, and garden landscape. The use of bamboo aggregate concrete can not only effectively reduce the self-weight of buildings and improve seismic performance, but also significantly reduce the impact on the environment, which is in line with the development trend of green buildings and low-carbon economy.

[0003] However, in the production process of bamboo aggregate concrete, the quality of bamboo aggregate becomes a key factor affecting the final material performance. Some natural characteristics of bamboo itself, such as bamboo septa and bamboo yellow parts, pose a challenge to the mechanical properties and stability of bamboo aggregate. Bamboo septa are usually hard, not easy to break, and have irregular shapes, which easily form stress concentration points in concrete. These stress concentration points will reduce the uniformity and overall strength of concrete, thereby affecting the stability and safety of the entire building structure; while bamboo yellow is located on the inner wall of bamboo and is a relatively soft part formed during the growth of bamboo. It does not contain vascular bundles and has relatively poor mechanical properties. In a humid environment, bamboo yellow easily absorbs water and expands, causing the volume of bamboo aggregate to change. When these bamboo aggregates are used in concrete, their expansion and contraction behaviors will be inconsistent with the deformation characteristics of concrete, thereby generating additional stress inside the concrete. These stresses will accelerate the formation and expansion of microcracks in concrete, reducing the durability and service life of concrete.

[0004] Therefore, in view of this, the inventor proposes a bamboo aggregate production device to solve the above technical problems. Summary of the invention

[0005] The object of the present invention is to provide a bamboo aggregate production device, aiming to solve the problem that the existing bamboo aggregate production device is difficult to remove bamboo yellow and bamboo septa, which easily leads to reduced uniformity and overall strength of bamboo aggregate concrete.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] A bamboo aggregate production device comprises a frame, an inner grinding structure, an outer grinding structure, a feeding structure and a slitting structure arranged along the length direction of the frame, wherein the inner grinding structure, the outer grinding structure, the feeding structure and the slitting structure are all arranged on the frame;

[0008] The cutting structure comprises a cutting component and a bamboo breaking component, wherein the bamboo breaking component is fixed on the cutting component; the cutting structure is used to cut the bamboo tube into bamboo aggregates;

[0009] The inner grinding structure comprises a first driving assembly and an inner grinding assembly connected to the first driving assembly, wherein the first driving assembly can drive the inner grinding assembly to extend into the bamboo tube or be pulled out of the bamboo tube;

[0010] The inner grinding assembly comprises a central axis rod, a bamboo yellow inner grinding unit arranged on the central axis rod, and a broken cone head arranged at the end of the bamboo yellow inner grinding unit. The bamboo yellow inner grinding unit can expand outward or contract inward along the radial direction of the central axis rod.

[0011] Further, the bamboo yellow internal grinding unit comprises a first sleeve, a second sleeve, a sliding sleeve and an internal grinding piece, the first sleeve and the second sleeve are fixedly mounted on the central axis, the sliding sleeve is slidably mounted on the central axis and can slide along the length direction of the central axis;

[0012] A tension spring is sleeved on the central shaft rod, and two ends of the tension spring are respectively connected to the first sleeve and the sliding sleeve, and the tension spring has a tendency to drive the sliding sleeve to approach the first sleeve;

[0013] The inner grinding piece is located at the outer periphery of the middle shaft, and the number of the inner grinding pieces is at least two;

[0014] When the middle shaft rotates, each inner grinding element can expand outwardly along the radial direction of the middle shaft.

[0015] According to the above technical solution, the first sleeve and the second sleeve are fixedly mounted on the central shaft rod, and the supporting part of the inner wear part and the sliding sleeve are slidably mounted on the central shaft rod and can slide freely along the length direction of the central shaft rod. In addition, a tension spring is sleeved on the central axis, and the two ends of the tension spring are respectively connected to the first sleeve and the sliding sleeve, so that the tension spring always has the pulling force to drive the sliding sleeve close to the first sleeve, thereby maintaining the compact layout of the inner grinding piece in the initial state, which is convenient for adapting to bamboo tubes with different inner diameters and has strong versatility; when the central axis starts to rotate, the inner grinding piece will be affected by centrifugal force, and when the centrifugal force is greater than the tension of the tension spring when the central axis rotates rapidly, the inner grinding piece will expand outward along the radial direction of the central axis, thereby closely contacting the inner wall of the bamboo tube, and as the central axis continues to rotate, the inner grinding piece performs continuous grinding action inside the bamboo tube, and since the inner grinding piece expands outward along the radial direction of the central axis, they can be evenly distributed on the inner wall of the bamboo tube, thereby ensuring the uniformity and consistency of the grinding effect, not only removing the bamboo yellow part of the inner wall of the bamboo tube, but also making its surface smoother and flatter, avoiding the influence of bamboo yellow on bamboo aggregate.

[0016] Further, the inner grinding element includes a mounting bar, a first connecting rod, a second connecting rod and a third connecting rod;

[0017] One end of the first connecting rod is hinged to the first sleeve, and the other end of the first connecting rod is hinged to one end of the mounting bar; one end of the second connecting rod is hinged to the second sleeve, and the other end of the second connecting rod is hinged to the other end of the mounting bar;

[0018] One end of the third connecting rod is hinged to the sliding sleeve, and the other end of the third connecting rod is hinged to the middle position of the second connecting rod;

[0019] Wherein, the first connecting rod and the second connecting rod are parallel to each other;

[0020] A grinding knife is detachably connected to the mounting bar, the grinding knife is in an S-shaped structure, and a plurality of blade teeth are formed on a side of the grinding knife away from the central axis rod.

[0021] In the initial state, due to the action of the tension spring, the sliding sleeve will be close to the first sleeve. At this time, the installation bar and the grinding knife thereon will be in a relatively compact state, ready to enter the inside of the bamboo tube for grinding. When the middle shaft rod starts to rotate, the first connecting rod and the second connecting rod will swing accordingly, and at the same time drive the installation bar and the grinding knife thereon to expand outward along the radial direction of the middle shaft rod. During the expansion process, the grinding knife will fit tightly on the inner wall of the bamboo tube and perform continuous grinding action as the middle shaft rod rotates. The first driving component drives the inner grinding piece to rotate while also driving the inner grinding piece to move inside the bamboo tube. The grinding knife of the present invention has an S-shaped structure that is just suitable for the driving action of the first driving component. The grinding knife with an S-shaped structure can produce a certain turbulence effect during the grinding process, making it easier to discharge the bamboo debris generated by grinding, avoiding the influence of debris accumulation on the grinding effect; moreover, the S-shaped design is more in line with air flow mechanics, which helps to reduce vibration and noise during the grinding process to a certain extent, and improve the stability of the grinding process.

[0022] Furthermore, the first driving assembly includes a base fixed on the frame, a slide slidably arranged on the base, and a first motor fixed on the slide, the base is provided with a first cylinder, the piston end of the first cylinder is connected to the slide, and is used to drive the slide to slide on the base; a turntable is rotatably connected to the slide, a rotating shaft is coaxially connected to the turntable, an end of the rotating shaft is coaxially and fixedly connected to the central axis rod, and the first motor is used to drive the turntable to rotate.

[0023] According to the above technical solution, when the first motor starts, it transmits the rotational power to the central axis through the turntable and the rotating shaft, thereby driving the cone breaking head to rotate. At the same time, the first cylinder starts to work, driving the slide to slide on the base, thereby driving the entire turntable and the central axis to move in a straight line. This composite motion mode enables the cone breaking head to not only perform rotational crushing, but also move and feed along the axial direction of the bamboo tube, thereby realizing all-round processing of the inner wall of the bamboo tube and the bamboo partitions. While crushing the bamboo partitions, the bamboo yellow in the bamboo tube is also polished, thereby improving the quality of the bamboo aggregate.

[0024] Furthermore, the cone breaking head comprises a first cone breaking and a second cone breaking, one end of the first cone breaking is connected to the bamboo yellow inner grinding unit, and the other end of the first cone breaking is connected to the second cone breaking;

[0025] The first breaking cone is an annular cylindrical structure, and a plurality of breaking cone teeth are formed around the first breaking cone;

[0026] The second breaking cone is formed with a spiral cutter, the second breaking cone comprises a breaking cone tip and a breaking cone end, and the cross section of the spiral cutter gradually increases along the direction from the breaking cone tip to the breaking cone end;

[0027] A plurality of hard alloy particles are arranged on the tip of the breaking cone.

[0028] According to the above technical solution, the breaking cone head is composed of a first breaking cone and a second breaking cone, which are closely connected to form a complete crushing structure. The first breaking cone is an annular cylindrical structure with a number of breaking cone teeth evenly distributed around it. These breaking cone teeth play a role of cutting and crushing during rotation. Carbide particles are used to increase the hardness of the second breaking cone. The second breaking cone is designed with a spiral knife. The cross-section of the spiral knife gradually increases from the tip of the breaking cone to the end of the breaking cone. This design enables the spiral knife to gradually increase the crushing force on the bamboo partition when it rotates and penetrates into the bamboo tube, effectively cope with the hardness of the bamboo partition part, thereby breaking the bamboo partition more quickly and improving the crushing effect. The second breaking cone plays a role of preliminary cutting and crushing the bamboo partition; when the second breaking cone completely passes through the bamboo partition, the first breaking cone plays a role of cutting and crushing the bamboo partition again. This collaborative operation method improves the processing efficiency.

[0029] Furthermore, the external grinding structure includes a fixed plate fixed on the frame, an electric telescopic cylinder is provided on the fixed plate, the free end of the electric telescopic cylinder extends downward and is fixedly connected to a mounting platform, and the electric telescopic cylinder can drive the mounting platform to rise or fall; a second motor is fixedly connected to the mounting platform, and a grinding wheel is connected to the output shaft of the second motor for grinding the outer circumference of the bamboo tube.

[0030] According to the above technical solution, the mounting table and the grinding wheel thereon are lowered to a position in contact with the outer periphery of the bamboo tube through the telescopic movement of the electric telescopic cylinder, and the second motor is started so that its output shaft drives the grinding wheel to rotate. During the rotation process, the grinding wheel is in close contact with the outer periphery of the bamboo tube and grinds the outer periphery of the bamboo tube through friction, thereby removing buds and part of the sheath rings, nodes and other structures on the bamboo tube.

[0031] Furthermore, the frame is provided with a guide rail, a work station plate and a second cylinder, the guide rail is arranged along the length direction of the frame, the work station plate is slidably arranged on the guide rail, and the second cylinder is used to drive the work station plate to reciprocate;

[0032] A third cylinder is fixedly arranged on the work station plate, and a clamping cylinder is connected to the piston end of the third cylinder. The third cylinder is used to drive the clamping cylinder to move upward or downward, and the clamping cylinder is used to clamp the bamboo tube.

[0033] According to the above technical solution, the work station plate is slidably set on the guide rail. Driven by the second cylinder, the work station plate can reciprocate along the guide rail. When the second cylinder receives a control signal, it will push or pull the work station plate to move on the guide rail from the previous work station to the next work station. The third cylinder is fixedly set on the work station plate. The main function of the third cylinder is to drive the clamping cylinder to move up and down. The clamping cylinder is used to clamp and release the bamboo tube; first, the third cylinder moves downward to drive the clamping cylinder downward, and the clamping cylinder clamps the bamboo tube. When the clamping cylinder completes clamping, the third cylinder drives the clamping cylinder and the bamboo tube to move upward. Driven by the second cylinder, the work station plate moves and then drives the bamboo tube to move to the next work station. This is repeated in sequence to realize the assembly line operation of the bamboo tube.

[0034] Further, the segmentation assembly includes a power unit, a first disc, a second disc, a tool mounting disc and a driving disc, the centers of the first disc, the second disc, the tool mounting disc and the driving disc are all provided with cutting holes, the tool mounting disc and the driving disc are arranged between the first disc and the second disc, a plurality of cutting knives are hinged on the tool mounting disc, and a rotating driving column is arranged at the middle position of each cutting knife;

[0035] The driving disk is evenly provided with a plurality of first arc-shaped grooves, and the rotating driving column is arranged in the first arc-shaped grooves;

[0036] The second circular disc is provided with a second arc groove, the driving disc is connected with a driving bar, and the driving bar is arranged in the second arc groove to drive the driving disc to rotate;

[0037] The power unit comprises a third motor mounted on the frame, the output shaft of the third motor is connected to a turntable, a support rod is eccentrically connected to the turntable, a connecting rod is hinged on the driving bar, and a free end of the connecting rod is hinged to the support rod.

[0038] According to the above technical solution, the tool mounting disk is located between the first disk and the second disk, and a plurality of cutting knives are hinged thereon. A rotating driving column is provided in the middle of the cutting knives. These driving columns are cleverly arranged in the first arc groove on the driving disk. When the driving disk rotates, the shape and angle change of the first arc groove will drive the rotating driving column and the cutting knives to perform corresponding rotational motion, and cooperate with multiple cutting knives to achieve the cutting action. The rotation of the driving disk is achieved by cooperating with the second arc groove and the driving bar on the second disk. The driving bar is connected to the driving disk and is arranged in the second arc groove. When the power unit provides driving force, the driving bar will move along the second arc groove, thereby driving the driving disk to rotate.

[0039] In the actual working process, the bamboo tube is first fed into the cutting hole, then the power unit is started, the third motor drives the turntable and the support rod to rotate, and through the lever action of the connecting rod, the driving bar moves along the second arc groove and drives the driving disk to rotate. The rotation of the driving disk causes the rotating driving column and the cutting knife in the first arc groove to perform corresponding rotational motion, thereby cutting the bamboo tube. After the cutting is completed, the bamboo tube is sent out of the cutting hole under the action of the feeding structure for the next step of processing, and the bamboo tube is cut repeatedly in sequence.

[0040] Furthermore, the bamboo splitting assembly includes a circular ring and a plurality of bamboo splitting knives, the circular ring is fixed on the first disc, and the circular ring is coaxially arranged with the cutting hole, and the bamboo splitting knives are used to split the bamboo tube into bamboo aggregates.

[0041] According to the above technical solution, the bamboo breaking knives are arranged around the ring and point to the center of the ring. When the bamboo tube passes through the cutting hole, it will contact the bamboo breaking knives on the ring. These bamboo breaking knives will divide the bamboo tube into multiple bamboo aggregates. The number and arrangement of the bamboo breaking knives can be adjusted according to actual needs to adapt to bamboo tubes of different specifications and types; the bamboo aggregates can then be collected and processed by other parts of the equipment.

[0042] Further, the feeding structure includes a guide platform, a push block slidably arranged on the guide platform, and a fourth cylinder, wherein the fourth cylinder is installed on one side of the guide platform to drive the push block to move;

[0043] When the bamboo tube is placed on the guide platform, the fourth cylinder is used to push the bamboo tube into the cutting structure.

[0044] According to the above technical solution, the polished bamboo tube is placed on the guide table, and then the fourth cylinder starts to work, and its piston rod extends to drive the push block to move along the length direction of the guide table. Since the push block is in direct contact with the bamboo tube, it will push the bamboo tube forward together; as the push block continues to move, the bamboo tube is gradually sent into the cutting structure, and the cutting structure cuts the bamboo tube into bamboo aggregates. The fourth cylinder reciprocates to drive the push block to work, thereby realizing the pushing work of the polished bamboo tube.

[0045] Beneficial effects of the present invention:

[0046] 1. When the bamboo tube of the present invention is conveyed to the processing area of ​​the inner grinding structure, the first driving component starts to work, driving the central axis rod and the bamboo yellow inner grinding unit and the cone breaking head thereon to extend into the interior of the bamboo tube. The first driving component drives the central axis rod to rotate, and the inner grinding piece is subjected to the effect of centrifugal force. When the centrifugal force is greater than the tension of the tension spring when the central axis rod rotates rapidly, the inner grinding piece expands outward along the radial direction of the central axis rod, thereby closely contacting the inner wall of the bamboo tube. As the central axis rod continues to rotate, the inner grinding piece performs continuous grinding action inside the bamboo tube. Since the inner grinding piece expands outward along the radial direction of the central axis rod, they can be evenly distributed on the inner wall of the bamboo tube, thereby ensuring the uniformity and consistency of the grinding effect, removing the bamboo yellow part of the inner wall of the bamboo tube to make its inner surface smooth and flat, and avoiding the influence of the bamboo yellow on the bamboo aggregate.

[0047] 2. The cone breaking head of the present invention is driven by the first driving component to move in the bamboo tube to remove the bamboo partitions in the bamboo tube; the external grinding structure is used to grind the outer periphery of the bamboo tube to avoid the problem of stress concentration points formed after the subsequent bamboo aggregate is mixed with concrete; the feeding structure is used to push the ground bamboo tube to the splitting component and the bamboo breaking component, and then split the bamboo tube into bamboo aggregates.

[0048] 3. The grinding knife of the present invention has an S-shaped structure and will generate a lot of heat when it contacts and rubs with the inside of the bamboo tube when rotating at high speed. The S-shaped grinding knife can produce a certain turbulence effect during the grinding process, which can reduce the friction temperature and make the bamboo debris generated by grinding easier to be discharged, thereby avoiding the influence of debris accumulation on the grinding effect; moreover, the S-shaped design is more in line with air flow mechanics, which helps to reduce vibration and noise during the grinding process to a certain extent, and improve the stability of the grinding process.

DETAILED DESCRIPTION

[0067] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0068] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0069] This embodiment provides a bamboo aggregate production device, such as Figures 1 to 16As shown, the machine frame 1 includes an inner grinding structure 2, an outer grinding structure 3, a feeding structure 4 and a slitting structure 5 arranged along the length direction of the machine frame 1, and the inner grinding structure 2, the outer grinding structure 3, the feeding structure 4 and the slitting structure 5 are all arranged on the machine frame 1. The outer grinding structure 3 is used to grind the outer circumference of the bamboo tube 7 to avoid the problem of stress concentration points in the produced bamboo aggregate concrete.

[0070] like Figures 4 to 8 As shown, the inner grinding structure 2 includes a first driving component 21 and an inner grinding component 22 connected to the first driving component 21. The first driving component 21 can drive the inner grinding component 22 to extend into the bamboo tube 7 or be pulled out of the bamboo tube 7. Further, as shown Figure 5 As shown, the inner grinding assembly 22 includes a central axis rod 221, a bamboo yellow inner grinding unit 222 arranged on the central axis rod 221, and a broken cone head 223 arranged at the end of the bamboo yellow inner grinding unit 222. The bamboo yellow inner grinding unit 222 can expand outward or contract inward along the radial direction of the central axis rod 221. When the bamboo tube 7 is transported to the processing area of ​​the inner grinding structure 2, the bamboo tube 7 is fixed by a fastening mechanism (not shown). The first driving assembly 21 starts to work, driving the central axis rod 221 and the bamboo yellow inner grinding unit 222 and the broken cone head 223 on the central axis rod 221 to extend into the interior of the bamboo tube 7. The first driving assembly 21 drives the central axis rod 221 to rotate, and then drives the bamboo yellow inner grinding unit 222 to rotate. During the rotation process, the bamboo yellow inner grinding unit 222 expands outward along the radial direction of the central axis rod 221 due to the action of centrifugal force, closely contacts the inner wall of the bamboo tube 7 and grinds the interior of the bamboo tube 7 to remove the bamboo yellow 71 in the bamboo tube 7. At the same time, the cone breaking head 223, driven by the first driving assembly 21, moves in the bamboo tube 7 to remove the bamboo partitions 72 in the bamboo tube 7;

[0071] Furthermore, if Figure 5 , Figure 6 and Figure 7 As shown, the bamboo yellow internal grinding unit 222 includes a first sleeve 2221, a second sleeve 2222, a sliding sleeve 2223 and an internal grinding piece 224. The first sleeve 2221 and the second sleeve 2222 are fixedly mounted on the central shaft 221 as supporting parts of the internal grinding piece 224; the sliding sleeve 2223 is slidably mounted on the central shaft 221 and is located between the first sleeve 2221 and the second sleeve 2222. The sliding sleeve 2223 can be moved along the length direction of the central shaft 221 (i.e. Figure 7The middle shaft 221 is provided with a tension spring 225, and the two ends of the tension spring 225 are respectively connected to the first sleeve 2221 and the sliding sleeve 2223. The tension spring 225 has a tendency to drive the sliding sleeve 2223 to approach the first sleeve 2221. When the middle shaft 221 starts to rotate, the inner grinding piece 224 will be affected by the centrifugal force. When the middle shaft 221 rotates rapidly, when the centrifugal force is greater than the tension of the tension spring 225, the inner grinding piece 224 expands outward along the radial direction of the middle shaft 221, thereby In close contact with the inner wall of the bamboo tube 7, as the central shaft 221 continues to rotate, the inner grinding piece 224 performs continuous grinding action inside the bamboo tube 7. Since the inner grinding piece 224 is extended outward along the radial direction of the central shaft 221, they can be evenly distributed on the inner wall of the bamboo tube 7, thereby ensuring the uniformity and consistency of the grinding effect, not only removing the bamboo yellow 71 part of the inner wall of the bamboo tube 7, but also making the inner surface smoother and flatter, avoiding the influence of the bamboo yellow 71 on the bamboo aggregate. Figure 5 As shown, in the initial state, due to the action of the tension spring 225, the sliding sleeve 2223 will be close to the first sleeve 2221, and at this time, the mounting bar 2241 and the grinding knife 2245 thereon will be in a relatively compact state (such as Figure 5 ), so that it is convenient to enter the bamboo tube 7 for grinding. When the middle shaft 221 starts to rotate, the first connecting rod 2242 and the second connecting rod 2243 will swing accordingly, and at the same time drive the mounting bar 2241 and the grinding knife 2245 thereon to expand outward along the radial direction of the middle shaft 221 (such as Figure 7 ), during the expansion process, the grinding knife 2245 will fit closely on the inner wall of the bamboo tube 7, and perform continuous grinding action as the central axis rod 221 rotates.

[0072] As a preferred embodiment, the inner grinding pieces 224 are evenly distributed on the outer periphery of the middle shaft 221, and the number of the inner grinding pieces 224 is at least two; Figure 5 and Figure 7 As shown, the number of the inner grinding parts 224 in this embodiment is three, which are evenly arranged around the axis of the central shaft 221. Of course, it can be understood that the number of the inner grinding parts 224 can also be multiple, which can be flexibly selected according to actual grinding requirements.

[0073] As a preferred embodiment, Figure 5 and Figure 7 As shown, the inner grinding member 224 includes a mounting bar 2241, a first connecting rod 2242, a second connecting rod 2243 and a third connecting rod 2244; Figure 7As shown, the bottom end of the first connecting rod 2242 is hinged to the first sleeve 2221, and the top end of the first connecting rod 2242 is hinged to the left end of the mounting bar 2241; the bottom end of the second connecting rod 2243 is hinged to the second sleeve 2222, and the top end of the second connecting rod 2243 is hinged to the right end of the mounting bar 2241; the bottom end of the third connecting rod 2244 is hinged to the sliding sleeve 2223, and the top end of the third connecting rod 2244 is hinged to the middle position of the second connecting rod 2243; wherein, the first connecting rod 2242 and the second connecting rod 2243 are parallel to each other;

This combined movement of feeding and rotation enables the cone breaking head 223 to not only perform rotational crushing, but also move and feed along the axial direction of the bamboo tube 7, thereby realizing all-round processing of the bamboo yellow 71 and the bamboo partition 72 on the inner wall of the bamboo tube 7, and can also adapt to bamboo tubes 7 of different diameters.

[0084] The cutting structure 5 comprises a cutting component 51 and a bamboo breaking component 52 , and the bamboo breaking component 52 is fixed on the cutting component 51 .

The centers of the first disc 512, the second disc 513, the tool mounting disc 514 and the driving disc 515 are all provided with cutting holes 516. The tool mounting disc 514 and the driving disc 515 are arranged between the first disc 512 and the second disc 513. A plurality of cutting knives 517 are hinged on the tool mounting disc 514. A rotating driving column 518 is arranged at the middle position of each cutting knife 517. A plurality of first arc grooves 5151 are evenly distributed on the driving disc 515.
