Description

Technical Field

[0001] This utility model relates to the field of bamboo shoot processing technology, specifically to a bamboo shoot cleaning device. Background Technology

[0002] Bamboo shoots, growing naturally in the mountains and forests, easily accumulate impurities such as mud, decaying leaves, and gravel on their surface. Dirt can easily hide in the crevices and folds of the outer sheath. During transportation and storage after harvesting, residual mucus from moisture-retaining treatments can attract dust and may even breed microorganisms. These impurities not only affect the taste but also pose potential health risks. As people's demands for food safety and quality increase, it is necessary to thoroughly remove the fine dirt and mucus from the surface and crevices. Therefore, professional cleaning of bamboo shoots is an essential step in ensuring their safety and quality for consumption.

[0003] According to the authorization announcement number (CN217906206U), a cleaning machine for processing edible bamboo shoots includes a cleaning tank with a feed inlet on the side wall and multiple sets of rotatable conveyor rollers installed on the inner wall of the tank, with the conveyor rollers located below the feed inlet. During actual cleaning operations, the operator feeds the bamboo shoots to be cleaned through the feed inlet, and the bamboo shoots immediately fall onto the surface of the conveyor rollers, which then drive the conveyor rollers to move them. Simultaneously, pre-set spray heads inside the cleaning tank are activated, continuously spraying clean water onto the moving bamboo shoots to complete the initial rinsing. When the bamboo shoots are conveyed to the cleaning brush area, the cleaning brushes reciprocate with the drive mechanism, thoroughly scrubbing the surface of the bamboo shoots.

[0004] The structure disclosed in this patent has defects in practical applications, specifically as follows: during the cleaning operation, the bamboo shoots can only maintain a single posture movement on the conveyor roller. When they are conveyed to the cleaning brush area, the cleaning brush can only contact and brush the upper surface of the bamboo shoots, and cannot cover the multiple sides of the bamboo shoots and areas such as the gaps between the bamboo shoot nodes, making it difficult to achieve all-round cleaning of the bamboo shoots, ultimately leading to the problem of incomplete cleaning. Utility Model Content

[0005] The purpose of this invention is to provide a bamboo shoot cleaning device that addresses the problem of low cleaning efficiency caused by the difficulty in achieving all-round scrubbing of bamboo shoots in existing technologies. This device can assist bamboo shoots in natural turning in multiple directions, thereby improving the cleaning efficiency of bamboo shoots.

[0006] This utility model is achieved through the following technical solution:

[0007] A bamboo shoot cleaning device includes: a frame; a supporting outer cylinder, which is installed at an incline on the frame, with a drain port at its bottom and multiple spray ports along its extension direction; two sealing end caps, which are respectively installed at the two ends of the supporting outer cylinder; a rotating inner cylinder, which passes through the inner side of the supporting outer cylinder, with the two sealing end caps passing through its two ends, forming a rotating fit with the two sealing end caps, and multiple water-permeable holes on its side wall; a cleaning mechanism, which passes through the rotating inner cylinder and is capable of scrubbing the bamboo shoots conveyed inside the rotating inner cylinder; and a drive assembly, which is installed on the frame and is capable of driving the rotating inner cylinder to rotate.

[0008] Furthermore, in this utility model, the cleaning mechanism includes: a rotating main shaft, which passes through the inner side of the rotating inner cylinder and is rotatable relative to the rotating inner cylinder; multiple cleaning components, which are respectively installed on the rotating main shaft; and at least one support component, one end of which is fitted onto the outside of the rotating main shaft and the other end of which is connected to the inner wall of the rotating inner cylinder; wherein the rotating main shaft is rotatable relative to the support component, thereby driving the multiple cleaning components to rotate relative to the rotating inner cylinder.

[0009] Furthermore, in this utility model, the cleaning assembly includes: a mounting sleeve fitted onto the outside of the rotating main shaft; and multiple cleaning bristles disposed on the outer wall of the mounting sleeve, with the free ends of the cleaning bristles extending away from the mounting sleeve.

[0010] Furthermore, in this utility model, the above-mentioned support assembly includes: a support sleeve, which is fitted onto the outside of the rotating main shaft and is rotatably engaged with the rotating main shaft; and at least one connecting rod, one end of which is connected to the support sleeve and the other end of which is connected to the inner wall of the rotating inner cylinder.

[0011] Furthermore, in this utility model, the cleaning mechanism further includes: a first support mounted on a frame; and a first motor mounted on the first support, the output shaft of which is connected to a rotating main shaft.

[0012] Furthermore, in this utility model, the aforementioned drive assembly includes: a driven gear ring, which is fitted onto the outer side of the rotating inner cylinder; a second support, which is mounted on the frame; a second motor, which is mounted on the second support; and a drive gear, which is mounted on the output shaft of the second motor and meshes with the driven gear ring.

[0013] Furthermore, in this utility model, a plurality of turning and decelerating ribs are installed on the inner wall of the rotating inner cylinder, and the plurality of turning and decelerating ribs are distributed along the axial direction of the rotating inner cylinder; the turning and decelerating ribs are used to turn the bamboo shoots in the rotating inner cylinder so that each surface of the bamboo shoots is in full contact with the cleaning mechanism, while slowing down the conveying speed of the bamboo shoots in the rotating inner cylinder.

[0014] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0015] 1. This utility model combines an inclined nested layout of a supporting outer cylinder and a rotating inner cylinder, with a counter-rotation cooperative operation mode of the rotating inner cylinder's revolution and the cleaning main shaft's rotation, which forcibly drives the bamboo shoots to continuously rotate, so that the front, back, sides and gaps of the bamboo shoots can all come into contact with the cleaning brush bristles, significantly improving the all-roundness and cleanliness of bamboo shoot cleaning.

[0016] 2. This utility model combines a material-turning deceleration rib, a cleaning brush bristle, and a connecting support rod in a triple linkage, which not only drives the bamboo shoots to turn over fully but also slows down the conveying speed of the bamboo shoots, ensuring that each bamboo shoot can be thoroughly cleaned within a sufficient cleaning time, significantly improving the overall cleaning uniformity.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0025] Example

[0026] Please refer to Figures 1 to 4 This utility model provides a bamboo shoot cleaning device. It includes a frame 1, a supporting outer cylinder 2, two sealing end caps 3, a rotating inner cylinder 4, a cleaning mechanism, and a drive assembly. The supporting outer cylinder 2 has a hollow structure and is fixedly installed on the frame 1 at a preset tilt angle. A drain port 13 is provided at the bottom of the supporting outer cylinder 2. Multiple spray ports 8 are also spaced apart along the supporting outer cylinder 2's extension direction. The two sealing end caps 3 are respectively fixedly assembled to the two ends of the supporting outer cylinder 2, forming a sealed cavity inside the supporting outer cylinder 2. Each sealing end cap 3 has an assembly port adapted to the rotating inner cylinder 4. The rotating inner cylinder 4 is... The shaft passes through the inner side of the outer supporting cylinder 2. The two ends of the rotating inner cylinder 4 pass through the assembly ports of the two sealing end caps 3 and extend to the outer side of the outer supporting cylinder 2. The rotating inner cylinder 4 and the assembly ports of the sealing end caps 3 form a rotating fit. Multiple water-permeable holes 14 are evenly opened on the side wall of the rotating inner cylinder 4. The high end of the rotating inner cylinder 4 forms the feed port, and the low end forms the discharge port. The cleaning mechanism is coaxially inserted inside the rotating inner cylinder 4 and can perform brushing and washing operations on the bamboo shoots conveyed inside the rotating inner cylinder 4. The drive component is installed on the frame 1 to drive the rotating inner cylinder 4 to rotate.

[0027] The operator continuously feeds the bamboo shoots to be cleaned into the inlet port of the rotating inner cylinder 4. Utilizing the inclined installation angle of the outer supporting cylinder 2, the bamboo shoots move along the axial direction of the rotating inner cylinder 4 from the inlet port to the outlet port under their own gravity. The water supply system supplies water to the sealed cavity of the outer supporting cylinder 2 through the spray interface 8. The cleaning water entering the sealed cavity seeps into the interior of the rotating inner cylinder 4 through the water-permeable holes 14 on the side wall, rinsing the bamboo shoots during their movement. Simultaneously, the driving cleaning mechanism remains rotating, and the contact friction between the cleaning mechanism and the surface of the bamboo shoots achieves the brushing operation, further... Further improve the cleaning effect; the drive component drives the rotating inner cylinder 4 to rotate synchronously. When the rotating inner cylinder 4 rotates, the friction between the inner wall of the rotating inner cylinder 4 and the bamboo shoot, the centrifugal force brought by the rotation, and the pushing force of the inner wall structure on the bamboo shoot work together to drive the bamboo shoot to continuously turn inside the rotating inner cylinder 4, so that all surfaces of the bamboo shoot can fully contact the cleaning mechanism and avoid cleaning dead corners; the wastewater generated during rinsing and brushing falls through the water permeable hole 14 into the bottom of the supporting outer cylinder 2, and is finally discharged through the drain port 13; the cleaned bamboo shoots continue to move to the discharge port of the rotating inner cylinder 4 for centralized collection.

[0028] Please refer to Figure 1 The multiple spray ports 8 on the outer cylinder 2 are connected to an external water inlet system, which includes at least a water supply pipeline, a pressure regulating valve, and a water control switch. The water supply pipeline is used to transport clean water, and the pressure regulating valve can adjust the water supply pressure to control the spray intensity. The multiple spray ports 8 are distributed in a ring around the circumference of the outer cylinder 2 and are also spaced apart along the axial direction of the outer cylinder 2. This allows a ring-shaped water flow to be formed within the sealed cavity of the outer cylinder 2, covering the outer circumference of the rotating inner cylinder 4, thus providing a thorough rinse to the bamboo shoots at different locations within the rotating inner cylinder 4 and ensuring that there are no dead angles in the rinse.

[0029] Please refer to Figure 3 and Figure 4 In some embodiments of this application, the cleaning mechanism includes a rotating main shaft 5, multiple cleaning components, and at least one support component. The rotating main shaft 5 is coaxially inserted inside the rotating inner cylinder 4. The multiple cleaning components are spaced apart on the rotating main shaft 5 along its axial direction. The support component is used to coaxially mount the rotating main shaft 5 inside the rotating inner cylinder 4. One end of the support component is fitted onto the outer peripheral wall of the rotating main shaft 5 to form a rotational fit, and the other end is fixedly connected to the inner wall of the rotating inner cylinder 4, allowing the rotating main shaft 5 to rotate independently relative to the rotating inner cylinder 4. When the bamboo shoots to be cleaned are conveyed inside the rotating inner cylinder 4, they are always within the annular space between the rotating main shaft 5 and the rotating inner cylinder 4. When the rotating main shaft 5 rotates, it synchronously drives the multiple cleaning components to rotate. The rotating cleaning components contact the surface of the bamboo shoots and generate friction, thereby achieving the brushing operation of the bamboo shoots.

[0030] The cleaning assembly includes a mounting sleeve 18 and multiple cleaning bristles 19. The mounting sleeve 18 is coaxially fitted onto the outer peripheral wall of the rotating main shaft 5 to form a fixed connection. The multiple cleaning bristles 19 are evenly distributed along the circumferential and axial directions of the mounting sleeve 18 on its outer outer wall. The free ends of each cleaning bristle 19 extend away from the mounting sleeve 18, so that the extension range of the cleaning bristles 19 can cover the annular space between the rotating main shaft 5 and the rotating inner cylinder 4. When the rotating main shaft 5 rotates, it synchronously drives the multiple cleaning bristles 19 to rotate through the mounting sleeve 18. During the rotation, the free ends of the cleaning bristles 19 contact the surface of the bamboo shoot and generate friction. The friction helps to clean the impurities on the surface of the bamboo shoot, completing the scrubbing operation.

[0031] Please refer to Figure 3 and Figure 4The support assembly includes a support sleeve 16 and at least one connecting rod 17. The support sleeve 16 is coaxially fitted onto the outer peripheral wall of the rotating main shaft 5 and forms a rotational fit with the rotating main shaft 5. To improve the stability of the fit, a rotating annular groove 20 is provided on the side wall of the rotating main shaft 5 corresponding to the assembly position of the support sleeve 16. The support sleeve 16 is embedded in the rotating annular groove 20 to form an axial limit. One end of the connecting rod 17 is fixedly connected to the outer peripheral wall of the support sleeve 16, and the other end is fixedly connected to the inner wall of the rotating inner cylinder 4. To ensure the support strength and suppress the shaking when the rotating main shaft 5 rotates, three connecting rods 17 are preferably provided, and the three connecting rods 17 are evenly distributed at equal intervals along the circumference of the support sleeve 16. During the cleaning operation, the drive assembly drives the rotating inner cylinder 4 to rotate clockwise, while the cleaning mechanism drives the rotating main shaft 5 to rotate counterclockwise. The counterclockwise rotation of the rotating inner cylinder 4 and the rotating main shaft 5 causes the bamboo shoots to form a more complex turning and moving trajectory within the rotating inner cylinder 4. Combined with the brushing action of the cleaning assembly, the cleaning effect is further improved.

[0032] It should be noted that multiple support sleeves 16 can be fitted onto the rotating main shaft 5 at intervals. Each support sleeve 16 has multiple connecting rods 17 mounted on its outer peripheral wall. The end of each connecting rod 17 furthest from the support sleeve 16 is fixedly connected to the inner wall of the rotating inner cylinder 4. When bamboo shoots are conveyed inside the rotating inner cylinder 4, they mainly rely on the tilt angle of the outer cylinder 2 and their own weight to move axially. If the moving speed is too fast, the bamboo shoots will not stay in the rotating inner cylinder 4 for long enough, leading to incomplete cleaning.

[0033] However, the multiple connecting rods 17 arranged in the circumferential direction of the support sleeve 16 can form a blocking structure. When the bamboo shoot moves rapidly along the axial direction and comes into contact with the connecting rod 17, the connecting rod 17 will block the bamboo shoot axially. Under the combined action of the rotating inner cylinder 4 and its own inertia, the blocked bamboo shoot will fall through the gap between two adjacent connecting rods 17. During this process, the blocking effect of the connecting rod 17 effectively reduces the axial movement speed of the bamboo shoot, thereby extending the cleaning time of the bamboo shoot in the rotating inner cylinder 4 and ensuring thorough cleaning.

[0034] It should be noted that the connecting rod 17 adopts a narrow-diameter structure design, making it unable to support bamboo shoots, thus preventing bamboo shoots from accumulating on the connecting rod 17 at the source. Simultaneously, the connecting rod 17 is fixedly connected to the support sleeve 16, and the support sleeve 16 is connected to the inner wall of the rotating inner cylinder 4 via the connecting rod 17. When the drive assembly drives the rotating inner cylinder 4 to rotate, the rotating inner cylinder 4 will synchronously drive the support sleeve 16 to rotate along with it via the connecting rod 17. During rotation, the narrow-diameter connecting rod 17 generates continuous dynamic disturbance. Even if bamboo shoots briefly come into contact with the connecting rod 17, they will be quickly carried away by the rotation of the connecting rod 17 and cannot remain stably on it, further preventing the accumulation of bamboo shoots.

[0035] Please refer to Figure 1 and Figure 2 In some embodiments of this application, the cleaning mechanism further includes a first support 6 and a first motor 7. The first support 6 is fixedly mounted on the frame 1, and the first motor 7 is fixedly mounted on the first support 6. The output shaft of the first motor 7 is connected to the end of the rotating main shaft 5 via a transmission connection. Combined with the reverse rotation design of the rotating inner cylinder 4 and the rotating main shaft 5, the rotation direction of the cleaning component is opposite to that of the rotating inner cylinder 4. This results in a large relative speed between the cleaning brush bristles 19 of the cleaning component and the bamboo shoots, which not only enhances the frictional scrubbing force of the brush bristles on the surface of the bamboo shoots but also disrupts the accumulation state of the bamboo shoots through relative motion, effectively improving the cleaning cleanliness.

[0036] In some embodiments of this application, the drive assembly includes a driven gear ring 12, a second support 9, a second motor 10, and a drive gear 11. The driven gear ring 12 is coaxially fixedly fitted onto the outer peripheral wall of the rotating inner cylinder 4. The second support 9 is fixedly mounted on the frame 1. The second motor 10 is fixedly mounted on the second support 9. The drive gear 11 is coaxially fixedly mounted on the output shaft of the second motor 10. The drive gear 11 meshes with the driven gear ring 12 for transmission. The second motor 10 can drive the drive gear 11 to rotate. Through the meshing of the drive gear 11 and the driven gear ring 12, power is transmitted to the rotating inner cylinder 4, thereby driving the rotating inner cylinder 4 to rotate.

[0037] Please refer to Figure 3 In some embodiments of this application, a plurality of turning and decelerating ribs 15 are fixedly installed on the inner wall of the rotating inner cylinder 4, and the turning and decelerating ribs 15 are distributed at intervals along the circumference and axial direction of the rotating inner cylinder 4. The turning and decelerating ribs 15 have the dual functions of turning bamboo shoots and slowing down the conveying speed: when the drive component drives the rotating inner cylinder 4 to rotate, the rotating inner cylinder 4 will synchronously drive the turning and decelerating ribs 15 to rotate. When the rotating turning and decelerating ribs 15 come into contact with the surface of the bamboo shoots, they will generate a circumferential thrust on the bamboo shoots, causing the bamboo shoots to detach from the inner wall of the rotating inner cylinder 4 and undergo a posture flip, ensuring that all surfaces of the bamboo shoots can fully contact the cleaning component and avoid cleaning dead corners; at the same time, the turning and decelerating ribs 15 will intermittently block the bamboo shoots during the rotation process, breaking the movement state of the bamboo shoots relying solely on gravity to slide rapidly along the inclined direction. When the bamboo shoots come into contact with the turning and decelerating ribs 15, they will generate reverse resistance, thereby effectively reducing the axial conveying speed of the bamboo shoots, extending the residence time of the bamboo shoots in the rotating inner cylinder 4, and ultimately improving the overall cleaning effect.

[0038] It should be noted that, under the combined action of the material turning deceleration rib 15, the cleaning brush filaments 19 and the connecting support rod 17, the conveying speed of bamboo shoots in the rotating inner cylinder 4 can be significantly reduced, effectively extending the residence time of bamboo shoots in the rotating inner cylinder 4, thus ensuring thorough cleaning of bamboo shoots in all aspects.

[0039] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
