Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, in particular to a banana stalk fiber extraction device. Background Art

[0002] Banana fiber is a kind of high-quality plant fiber. This fiber not only has light weight and strong air permeability, but also has fast moisture absorption and moisture discharge, excellent antibacterial performance, and high economic value. It is suitable for making various medium and high-grade ties, shirts, suits and other fabrics. Therefore, in the treatment of banana stalks, it is necessary to extract the fibers inside the banana stalks through an extraction device.

[0003] When the existing banana stalk fiber extraction device is in use, although it can effectively extract the fibers inside the banana stalks, during the removal and transportation of the banana stalks, due to the low disassembly and assembly efficiency of the removal roller, after a long time of use, it will be wound due to more fibers adsorbed on the surface. In this case, not only is the device prone to blockage during the transportation of banana stalks, but also the fiber extraction efficiency will be reduced.

[0004] After retrieval, the Chinese utility model patent with the publication number of CN202465966U discloses a fiber extraction device for plant stems and leaves, including a main frame, on which a roller is movably supported. The roller is driven by a driving device. A number of scraping blades are arranged on the outer circumferential surface of the roller. A cover is arranged outside the roller. One end of the cover is hinged to the main frame. The other end of the cover is provided with a feeding port. A feeding conveyor belt and a pressing roller are arranged on the main frame at the feeding port. This application drives the roller to rotate to extract fibers by using the scraping blades on its surface. However, the continuous scraping of the scraping blades on the plant stems and leaves will inevitably entangle filamentous fibers on the surface of the roller. Therefore, the long-term operation of this device will also cause the problem of roller blockage, resulting in unsmooth transportation and reduced fiber extraction efficiency.

[0026] Embodiment

[0027] Referring to the attached Figures 1-5 , the present application provides a banana stalk fiber extraction device, which includes a device main body 1. An extraction mechanism, a transmission mechanism and an adjustment mechanism are provided on the device main body 1. The extraction mechanism includes a removal roller 5 and a disassembly and assembly component. The removal roller 5 extracts fibers by breaking the glue of the banana stalk. The disassembly and assembly component is used for the disassembly and assembly of the removal roller 5. In order to avoid a large amount of fibers adhering to and winding around the outside of the removal roller 5, resulting in the blocking of the removal teeth on the surface of the removal roller 5, the removal roller 5 can be regularly disassembled for cleaning and maintenance to ensure the cleanliness of the surface of the removal roller 5. The disassembly and assembly component includes a mounting plate 101, a mounting block 3 and a connection box 6. The mounting plate 101 is fixedly connected to both sides of the top of the device main body 1. The mounting block 3 is rotatably connected to both sides of the removal roller 5. The inside of the connection box 6 is provided with a connection card rod 7 and a telescopic card rod 8 that are engaged with each other. The mounting plate 101 and the mounting block 3 are fixedly connected by the connection card rod 7 and the telescopic card rod 8. That is, through the connection card rod 7 and the telescopic card rod 8, the fixation between the removal roller 5 and the mounting plate 101 can be realized. When the two are engaged with each other, the connection card rod 7 cannot move further inside the connection box 6. Therefore, the removal roller 5 can be stably installed, thereby ensuring the stability and smoothness of removing the glue on the stalk.

[0028] Preferably, the device body 1 includes a base and a frame. The frame is fixedly connected to the top of the base. The base supports the whole device, and the frame is used to install other components. The number of the mounting plates 101 is two. The two mounting plates 101 are respectively fixedly connected to the two sides at the top of the frame. The two mounting plates 101 are located on both sides of the middle of the top of the frame, and sliding grooves 4 are formed on the sides of the two mounting plates 101 close to each other. The number of the mounting blocks 3 is two, and the two mounting blocks 3 are respectively slidably connected to the mounting plates 101 at the two sliding grooves 4. The sliding grooves 4 can provide guiding and limiting effects for the mounting blocks 3, so that the mounting blocks 3 can only move in the vertical direction in the sliding grooves 4. The rejection roller 5 is located between the two mounting blocks 3. Therefore, the rejection roller 5 can be loaded and unloaded by loading and unloading the mounting blocks 3.

[0029] Preferably, the connection box 6 is fixedly connected to the inner bottom end of the mounting plate 101, and card holes are formed at the top of the connection box 6 and on the plate body of the mounting plate 101 inside the connection box 6. The connection card rod 7 is located at the card hole on the connection box 6, and the top end of the connection card rod 7 is fixedly connected to the mounting block 3. The mounting plate 101 is slidably connected with a telescopic rod 9 at the card hole on its plate body. The telescopic card rod 8 is fixedly connected to one end of the telescopic rod 9.

[0030] Preferably, a pull block 11 is fixedly connected to the end of the telescopic rod 9 away from the rejection roller 5. The pull block 11 can pull the telescopic card rod 8 to move. Therefore, the telescopic card rod 8 can be pulled to move away from the connection card rod 7. At this time, the movement of the connection card rod 7 is no longer restricted, so the rejection roller 5 can be taken out. A spring 10 is fixedly connected between the pull block 11 and the mounting plate 101 outside the telescopic card rod 8. Through its own elastic force, the spring 10 can keep the telescopic card rod 8 in contact with the card rod 7 under normal conditions. Therefore, the two can maintain the state of being mutually engaged under normal conditions, and the stability of the rejection roller 5 after installation can be ensured.

[0031] Preferably, the transmission mechanism includes two conveyor belts 2. The two conveyor belts 2 are respectively used to convey the banana stalks before processing and the stalk fibers after processing. Two support rollers are rotatably connected to both sides of the rejection roller 5 at the top of the frame. The running directions of all the support rollers are the same. The two conveyor belts 2 are located on both sides of the rejection roller 5, and the conveyor belts 2 are sleeved outside the two support rollers. Motors are built in the support rollers and the rejection roller 5. The number of the rejection rollers 5 is two. The two rejection rollers 5 are arranged side by side vertically and are in a tangent state. Their operation can be controlled by a controller to facilitate the realization of their synchronous reverse rotation. The controller can adopt an 8051 single-chip microcomputer. The two rejection rollers 5 rotate synchronously and in opposite directions.

[0032] Preferably, support frames are fixedly connected to both ends of the side wall of the frame on both sides of the conveyor belt 2. Fixing grooves 15 are formed inside the support frames, and threaded rods 12 are rotatably connected to the inside of the fixing grooves of the support frames. One end of each threaded rod 12 is fixedly connected to a knob 13, and threaded sleeves are threadedly connected to the outside of the threaded rods 12. The threaded sleeves are slidably connected to the support frames at the fixing grooves 15. By turning the threaded rod 12, the position of the threaded sleeve can be adjusted, and the threaded sleeve can drive the baffle 14 to move, thereby adjusting its relative position with respect to the conveyor belt 2. The adjusting mechanism includes a plurality of baffles 14 located on both sides of the two conveyor belts 2. Each baffle 14 includes a fixed plate body 1401 and a movable plate body 1402. The tops of the fixed plate body 1401 and the movable plate body 1402 are rotatably connected by a damping rotating shaft. The fixed plate body 1401 is fixedly connected between two threaded sleeves on the same side. By flipping the movable plate body 1402 to buckle on the surface of the conveyor belt 2, two movable plate bodies 1402 can form a limiting channel on the surface of the conveyor belt 2, thereby ensuring the stable transmission of banana stalks on the conveyor belt 2. By adjusting the relative position of the baffle 14 and the conveyor belt 2, the width of the limiting channel can also be controlled, so as to adapt to the transmission of stalks of different lengths.

[0033] Working principle: When using this device, after the banana stalk fiber is extracted and processed through the long-term operation of this device, in order to avoid excessive fiber adsorption and entanglement on the surface of the removal roller 5, ensure the contact effect between the removal roller 5 and the surface of the banana stalk, and avoid blockage on the surface of the removal roller 5, the removal roller 5 can be regularly disassembled to clean the impurities on the surface of the removal roller 5;

[0034] During the process of disassembling the removal roller 5, the pull block 11 can be pulled to drive the telescopic locking rod 8 fixedly connected to the telescopic rod 9 to perform telescopic movement along the inner wall of the connection box 6 until the connection locking rod 7 is disengaged from the telescopic locking rod 8. At this time, the movement of the connection locking rod 7 will no longer be restricted, so the mounting block 3 can be taken out of the sliding groove 4 to achieve the disassembly effect of the removal roller 5;

[0035] Finally, when using the conveyor belt 2 to transport banana stalks and stalk fibers, by flipping the movable plate body 1402 to cover the surface of the conveyor belt 2, a limiting channel can be formed on the conveyor belt 2 to facilitate the stable transportation of banana stalks; in addition, by turning the knob 13 to rotate the threaded rod 12, the position of the baffle 14 can also be adjusted by using the threaded sleeve, and by adjusting its relative position with respect to the conveyor belt 2, the width of the limiting channel formed by the movable plate body 1402 can also be adjusted, so as to be suitable for the stable transportation of stalks of different lengths.

[0036] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. The protection scope of the present utility model shall be subject to the protection scope of the said claims.
