Description

Technical Field

[0001] This utility model relates to the technical field of bamboo shoot processing equipment, specifically a bamboo shoot cutting and grading integrated machine. Background Technology

[0002] Bamboo shoots, a common agricultural product, require peeling and tip removal during processing. The tips of bamboo shoots are hard and inedible, so they need to be cut off, leaving the edible parts for further processing. Currently, bamboo shoot tip removal is typically done by using a conveyor belt to transport the bamboo shoots to a cutter for tip removal.

[0003] In the existing technology, patent CN202510104568.6 proposes an automatic bamboo shoot tip cutting production line. This technology, by setting up a lifting conveyor belt and a feeding component, achieves feeding of bamboo shoots one by one with the tips facing the same direction, reducing manual intervention and improving processing efficiency. However, this technology still has certain limitations: on the one hand, its tip cutting operation is relatively simple, only able to complete the tip cutting task, and cannot perform grading of bamboo shoots; on the other hand, its structure is relatively complex, the equipment cost is high, and in practical applications, it is not adaptable enough to bamboo shoots of different lengths and specifications, making it difficult to meet the needs of grading bamboo shoots of different specifications during bamboo shoot processing.

[0004] In summary, the existing technology suffers from several problems: bamboo shoot processing equipment is inefficient and labor-intensive in the cutting and grading stages, and cannot achieve automated grading, thus failing to meet the demands of modern bamboo shoot processing enterprises for efficient and automated production. To address these issues, this invention proposes an integrated bamboo shoot cutting and grading machine, aiming to overcome the shortcomings of existing technologies, achieve efficient bamboo shoot cutting and grading, improve production efficiency, and reduce labor intensity.

[0018] (III) Beneficial Effects

[0019] This utility model provides an integrated machine for cutting and grading bamboo shoots, which has the following beneficial effects:

[0020] 1. This utility model achieves automated cutting and grading of bamboo shoots by setting up a first conveyor belt and multiple second conveyor belts, combined with a cutting component and a pressing component. During the conveying process, the bamboo shoots are cut by the cutting blade, and simultaneously graded according to different specifications of bamboo shoots through different conveyor belt conveying distances. This design not only improves cutting efficiency but also achieves automated grading of bamboo shoots, eliminating the need for manual grading, greatly improving production efficiency and reducing labor intensity. Compared with existing technologies, this utility model effectively improves the efficiency of cutting and grading (discharging) processes, avoids the step of manually distinguishing different specifications of tender bamboo shoots, significantly reduces manual intervention, and lowers production costs.

[0021] 2. The conveying component of this utility model is rationally designed. By adjusting the number and spacing of the second conveyor belts, it can flexibly adapt to bamboo shoots of different lengths. Simultaneously, by precisely controlling the speed of the main drive motor and the conveying distance of the conveyor belts, accurate grading of the bamboo shoots can be achieved, ensuring the consistency of the bamboo shoot dimensions after grading and meeting the stringent market requirements for bamboo shoot grading. Furthermore, the grading method of this utility model can be adjusted according to actual needs. By changing the conveying distance of the conveyor belts or increasing the number of conveyor belts, more detailed grading can be achieved, further increasing the added value of the product.

[0022] 3. This utility model utilizes the instability and falling of bamboo shoots. When bamboo shoots are conveyed to the feeding area, the relatively shorter conveyor belt rotates in place, causing the tip of the bamboo shoot to suspend in the air. The tip of the bamboo shoot, which is pressed down by the pressure head, can continue to move forward, while those not pressed down fall naturally into the basket in the feeding area, thus achieving the grading of bamboo shoots of different lengths. Since only a portion of the conveyor belt is broken, the pressure head only needs to rely on gravity to slightly press down on the tip of the bamboo shoot, ensuring that the bamboo shoot does not fall and is not damaged. It also allows bamboo shoots of different lengths to pass through. The purpose of grading bamboo shoots by length is twofold: firstly, it meets packaging requirements, as each length corresponds to a different packaging bag; secondly, it enhances aesthetics, as uniform size and consistent length are more visually appealing and meet market demands.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying anything.

[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0038] Example 1, please refer to Figures 1 to 10 This utility model provides a technical solution: a bamboo shoot cutting and grading integrated machine, which is used to cut and grade bamboo shoot heads, including a lower support frame 1, an upper support frame 2, a pressing component, a conveying component, a cutting component, and a main drive motor 3. The upper support frame 2 is fixedly installed on the lower support frame 1. The cutting component, the pressing component, and the main drive motor 3 are all installed on the upper support frame 2. The main drive motor 3 is connected to the conveying component and the pressing component respectively.

[0039] The lower support frame 1 serves as the basic support structure of the equipment, bearing the upper support frame 2, conveying components, and other major components. This ensures the overall stability and reliability of the equipment, providing a solid foundation for the normal operation of the bamboo shoot cutting and grading integrated machine. The upper support frame 2 is used to install the cutting components, pressing components, and main drive motor 3, providing a stable mounting platform for these components and ensuring that they maintain precise positioning and stable performance during operation.

[0040] The conveying components include a first conveyor belt 7, multiple second conveyor belts 9, and multiple rotating shafts 5. Each rotating shaft 5 is rotatably mounted on a lower support frame 1, and the rotating shafts 5 are arranged parallel to each other along the length of the lower support frame 1. The first conveyor belt 7 is wrapped around two rotating shafts 5, and the second conveyor belts 9 are wrapped around at least two rotating shafts 5. The first conveyor belt 7 and each of the second conveyor belts 9 are arranged along the width of the lower support frame 1, and a slit 8 is formed between the first conveyor belt 7 and an adjacent second conveyor belt 9. Among the second conveyor belts 9, the lateral conveying distance of the second conveyor belt 9 that is farther away from the first conveyor belt 7 is longer. Grooves for placing bamboo shoots are provided on both the first conveyor belt 7 and the second conveyor belt 9.

[0041] The conveying component operates synchronously via a first conveyor belt 7 and multiple second conveyor belts 9, driven by a rotating shaft 5, to transport bamboo shoots. A slit 8 is formed between the first conveyor belt 7 and adjacent second conveyor belts 9 for head-cutting operations. The lateral conveying distances of each second conveyor belt 9 differ; the further the second conveyor belt 9 is from the first conveyor belt 7, the longer its conveying distance, thus enabling the grading and feeding of bamboo shoots. Grooves on the first and second conveyor belts 7 and 9 are used to stably hold the bamboo shoots, preventing them from rolling or shifting during transport, ensuring the bamboo shoots maintain accurate positioning during head-cutting and grading operations, thereby improving processing precision and efficiency.

[0042] The main drive motor 3 is connected to each rotating shaft 5, and the main drive motor 3 drives each rotating shaft 5 to rotate synchronously in the same direction.

[0043] The main drive motor 3 drives each rotating shaft 5 to rotate synchronously and in the same direction through a transmission connection, ensuring the smooth operation of the conveyor belt, realizing continuous conveying and grading of bamboo shoots, and guaranteeing the stability and reliability of the equipment operation. At the same time, the synchronous rotation of each rotating shaft 5 ensures that the conveying direction and speed of the first conveyor belt 7 and each second conveyor belt 9 are consistent, achieving stable conveying of bamboo shoots.

[0044] The cutting component includes a cutting blade 21, the cutting edge of which is located at the cutting slit 8. The cutting blade 21 is used to cut the bamboo shoot tips conveyed by the conveying component. The first conveyor belt 7 conveys the cut bamboo shoot tips to the bamboo shoot tip unloading area B, and each of the second conveyor belts 9 conveys bamboo shoot bodies of different specifications to the bamboo shoot body unloading area. The unloading area B is located below the end of the first conveyor belt 7, and a material frame for holding bamboo shoot tips is placed on the ground below the unloading area B. The bamboo shoot body unloading area refers to... Figure 5 The bamboo shoots are divided into primary feeding area C, secondary feeding area D, and tertiary feeding area E. Below each feeding area, there is a material frame placed on the ground to hold bamboo shoots of the corresponding length and specifications.

[0045] The cutting blade 21, located at the cutting slit 8, is used to cut the tips of the bamboo shoots being transported from the opposite direction. The first conveyor belt 7 delivers the cut tips to the tip feeding area B, while the second conveyor belt 9 transports the bamboo shoot bodies to different feeding areas according to their length specifications: primary feeding area C, secondary feeding area D, tertiary feeding area E, etc. Feeding frames are placed below each feeding area to separate the tips from the bodies and collect them in a graded manner. Because the conveying lengths of the different second conveyor belts 9 are different, when the bamboo shoot body is short, its center of gravity is closer to the side where the first conveyor belt 7 is located, so the bamboo shoot body will fall first at the primary feeding area C due to its own gravity. When the bamboo shoot body is long, its center of gravity is farther from the side where the first conveyor belt 7 is located, so the bamboo shoot body will fall at the secondary feeding area D or tertiary feeding area E, etc., due to its own gravity, thus achieving the grading and selection of bamboo shoot bodies of different specifications. The bamboo shoot bodies falling into the feeding frames are of relatively uniform specifications.

[0046] refer to Figure 4 , Figure 5 In the implementation of this technical solution, two workstations were used. Figure 4 or Figure 5 The dotted line running from left to right across the entire equipment represents the workstation boundary line. This technical solution can be implemented in both dual-workstation and single-workstation configurations. When implemented in a dual-workstation configuration, it can significantly improve production efficiency.

[0047] Specifically, a first sprocket 10 is fixedly mounted on the output shaft end of the main drive motor 3, and a fifth sprocket is fitted on the outer wall of each rotating shaft 5. A first chain is wound around the first sprocket 10 and each fifth sprocket, and the first chain meshes with the first sprocket 10 and each fifth sprocket respectively. The main drive motor 3 is connected to each rotating shaft 5 through the first sprocket 10, the first chain, and each fifth sprocket.

[0048] The main drive motor 3 includes, but is not limited to, a stepper motor or a servo motor. The main drive motor 3 drives each rotating shaft 5 to rotate synchronously and in the same direction through a sprocket and chain transmission system, ensuring smooth operation of the conveying components and achieving continuous conveying and grading of bamboo shoots. After the main drive motor 3 starts, its output shaft drives the first sprocket 10 to rotate. The first sprocket 10 drives each fifth sprocket to rotate via the first chain, and the fifth sprockets drive the rotating shafts 5 to rotate, thus achieving synchronous and unidirectional rotation of each rotating shaft 5.

[0049] refer to Figure 4 , Figure 5In actual implementation, this technical solution employs six rotating shafts 5: a first rotating shaft 501, a second rotating shaft 502, a third rotating shaft 503, a fourth rotating shaft 504, a fifth rotating shaft 505, and a sixth rotating shaft 506, to demonstrate the feasibility of multi-stage separation of the bamboo shoot body. At least three second conveyor belts 9 are used: second conveyor belt a901, second conveyor belt b902, and second conveyor belt c903.

[0050] The first conveyor belt 7 is wound and fitted around the outer walls of the first rotating shaft 501 and the second rotating shaft 502; the second conveyor belt a901 is wound and fitted around the outer walls of the first rotating shaft 501 and the third rotating shaft 503; the second conveyor belt b902 is wound and fitted around the outer walls of the first rotating shaft 501 and the fourth rotating shaft 504; and the second conveyor belt c903 is wound and fitted around the outer walls of the first rotating shaft 501 and the sixth rotating shaft 506 (or the fifth rotating shaft 505). The length of the first conveyor belt 7 is less than the length of the second conveyor belt a901, which is less than the length of the second conveyor belt b902, which is less than the length of the second conveyor belt c903.

[0051] Specifically, the conveying component also includes multiple first bearing seats 4, each of which is fixedly installed on the lower support frame 1, and the two ends of the rotating shaft 5 are rotatably installed with two first bearing seats 4 respectively.

[0052] The first bearing housing 4 is used to support and ensure the stable rotation of the rotating shaft 5, thus ensuring the smooth operation of the conveying component.

[0053] More specifically, the rotating shaft 5 adopts a rod structure, and multiple sixth sprockets are fitted on the outer wall of the rotating shaft 5, with the rotating shaft 5 fixedly connected to the sixth sprockets. The first conveyor belt 7 includes a third chain 701 and a flexible convex-concave plate 702. The third chain 701 is wound around two corresponding sixth sprockets on the two rotating shafts 5, and the third chain 701 meshes with the two sixth sprockets. The convex-concave plate 702 is laid on the side of the third chain 701 away from the sixth sprockets, and the convex-concave plate 702 is fixedly connected to a portion of the chain links of the third chain 701.

[0054] The first conveyor belt 7 is driven by the cooperation of the rotating shaft 5 and the sixth sprocket. The first conveyor belt 7 consists of a third chain 701 and a flexible concave-convex plate 702. The grooves on the concave-convex plate 702 are used to stably hold the bamboo shoots, ensuring they do not roll or shift during transport, thereby improving the accuracy of cutting and grading. The concave-convex plate 702 is made of, but is not limited to, soft materials such as rubber or nylon. When the rotating shaft 5 rotates, it drives the sixth sprocket to rotate, which in turn drives the third chain 701 to rotate and move, and the third chain 701 drives the concave-convex plate 702 to rotate and move.

[0055] Specifically, the cutting head component also includes a cutting head motor 20, which is fixedly mounted on the upper support frame 2. The cutting head blade 21 is fixedly mounted on the output shaft end of the cutting head motor 20, and the cutting head motor 20 drives the cutting head blade 21 to rotate at high speed.

[0056] The cutting head motor 20 includes, but is not limited to, a servo motor or a stepper motor. The cutting head motor 20 is used to drive the cutting head blade 21 to rotate at high speed.

[0057] Specifically, the pressing component includes a fourth chain, multiple rotating shafts 12, and multiple pressing assemblies. Each rotating shaft 12 is rotatably mounted on the upper support frame 2, and the rotating shafts 12 are arranged parallel to each other along the length of the upper support frame 2. The main drive motor 3 is connected to each rotating shaft 12, and drives each rotating shaft 12 to rotate synchronously in the same direction. The pressing assemblies are mounted on two adjacent rotating shafts 12, and the pressing assemblies are staggered sequentially, with each pressing assembly located above each of the second conveyor belts 9.

[0058] The rotating shaft 12 is rotatably mounted on the upper support frame 2 via the second bearing seat 13. The pressing component, through the cooperation of the fourth chain, multiple rotating shafts 12, and pressing components, presses the bamboo shoots on the conveyor belt, ensuring the bamboo shoots remain stable during transport and preventing them from shifting or rolling due to vibration or inertia, thereby improving the accuracy and stability of the cutting and grading operations. The main drive motor 3 drives each rotating shaft 12 to rotate synchronously in the same direction via a transmission connection. The rotating shafts 12 drive the pressing components to rotate, and the pressing components are used to press the bamboo shoots. The pressing components are staggered sequentially and are located above each of the second conveyor belts 9. This arrangement allows the pressing components to press the bamboo shoots on the second conveyor belts 9, keeping the bamboo shoots stable.

[0059] More specifically, a second sprocket 11 is fixedly mounted on the output shaft end of the main drive motor 3, and a seventh sprocket is fitted on the outer side wall of the end of each rotating shaft 12. A fourth chain is wound around the second sprocket 11 and each of the seventh sprockets, and the fourth chain meshes with the second sprocket 11 and each of the seventh sprockets respectively. The main drive motor 3 is connected to each rotating shaft 12 through the second sprocket 11, the fourth chain, and each of the seventh sprockets.

[0060] The output shaft of the main drive motor 3 is fixedly equipped with a second sprocket 11. When the main drive motor 3 starts, the second sprocket 11 rotates accordingly. As the second sprocket 11 rotates, it drives the seventh sprockets to rotate synchronously via the fourth chain. The rotation of the seventh sprockets drives the rotating shafts 12 to rotate synchronously in the same direction. The rotation of the rotating shafts 12 presses the bamboo shoots on the conveyor belt through a pressing assembly, ensuring the bamboo shoots remain stable during transport and preventing them from shifting or rolling due to vibration or inertia.

[0061] More specifically, the pressing assembly includes a third sprocket 15, a fourth sprocket 19, a second chain 14, and multiple pressing components. The third sprocket 15 and the fourth sprocket 19 are respectively mounted on two adjacent rotating shafts 12, and the rotating shafts 12 are fixedly installed with either the third sprocket 15 or the fourth sprocket 19. The second chain 14 is wound around the third sprocket 15 and the fourth sprocket 19, and the second chain 14 meshes with both the third sprocket 15 and the fourth sprocket 19. Each pressing component is installed on a link of the second chain 14, and the pressing components are arranged along the length of the second chain 14.

[0062] The pressing assembly, driven by the third sprocket 15, the fourth sprocket 19, and the second chain 14, moves multiple pressing components along the conveyor belt to press the bamboo shoots on the second conveyor belt 9. This ensures the bamboo shoots remain stable during transport, preventing them from shifting or rolling due to vibration or inertia, thereby improving the accuracy and stability of the cutting and grading operations. When the rotating shaft 12 rotates, the third sprocket 15 and the fourth sprocket 19 rotate synchronously. As the third sprocket 15 and the fourth sprocket 19 rotate, the second chain 14 moves accordingly. With the movement of the second chain 14, the pressing components move back and forth, pressing the bamboo shoots on the second conveyor belt 9 during this movement.

[0063] More specifically, the pressing component includes a stainless steel recess 16, a nylon sleeve 17, and a pressing head 18. The stainless steel recess 16 is fixedly installed with the links of the second chain 14. One end of the nylon sleeve 17 is fixedly connected to the stainless steel recess 16. The pressing head 18 is inserted into the end of the nylon sleeve 17 away from the chain link, and the pressing head 18 is slidably connected to the nylon sleeve 17.

[0064] The pressing component, through a combination of a stainless steel recess 16, a nylon sleeve 17, and a pressing head 18, achieves stable pressing of the bamboo shoots on the second conveyor belt 9. The stainless steel recess 16 provides structural support, while the nylon sleeve 17 allows the pressing head 18 to flexibly adjust its height through sliding, ensuring effective pressing while minimizing damage to the bamboo shoot surface and protecting its appearance. The pressing head 18 presses down on the bamboo shoot body using its own weight without damaging it, ensuring the bamboo shoot remains stable during transport and preventing it from shifting or rolling due to vibration or inertia. A guide groove is formed along the length of the nylon sleeve 17, and a pin 6 is fixedly mounted on the pressing head 18, slidably connected to the nylon sleeve 17 through the guide groove.

[0065] Example 2, please refer to Figures 1 to 10 The main difference between this embodiment and embodiment one is that the rotating shaft 5 is a rotating roller, the first conveyor belt 7 and each of the second conveyor belts 9 are rubber conveyor belts, and the rubber conveyor belts are provided with multiple grooves for placing bamboo shoots.

[0066] This design employs a rotating roller as the rotating shaft 5 and uses rubber conveyor belts as the first conveyor belt 7 and the second conveyor belt 9. Multiple grooves are opened on the conveyor belts to place bamboo shoots, ensuring that the bamboo shoots are placed stably during the conveying process and preventing them from rolling or shifting. At the same time, the flexibility and wear resistance of the rubber conveyor belts improve the durability and operational stability of the equipment.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description.
