Description

Technical Field

[0001] This invention relates to the technical field of bamboo leaf crushing devices, specifically a bamboo leaf crushing device with an energy-saving motor. Background Technology

[0002] Bamboo leaves, a byproduct of bamboo processing, are characterized by high fiber content and strong biodegradability, and are widely used in feed, biomass energy, papermaking, and pharmaceuticals. However, the dense and tough fiber structure of bamboo leaves leads to problems such as high energy consumption, low efficiency, and uneven particle size in traditional pulverizing equipment. Energy-saving motors, through optimized electromagnetic design, the use of low-loss materials, and improved manufacturing processes, can significantly reduce copper loss, iron loss, and wind resistance loss during motor operation. Applying energy-saving motors to bamboo leaf pulverizing devices can reduce energy consumption, lower long-term operating costs, and improve equipment stability and pulverizing quality, which aligns with the trends of green energy-saving manufacturing and sustainable development. Using a branch pulverizer to pulverize cut leafy branches or trunks on-site before transporting them for composting or biomass power generation is a currently popular and relatively environmentally friendly and efficient processing method.

[0003] In the prior art, such as the branch shredder disclosed in CN206716133U, the problem of manually sieving and classifying branch fragments during the screening process is solved, which consumes a lot of time and manpower. The key points of its technical solution are: it includes a machine casing, on which a discharge channel is provided; a cutting tool is rotatably connected inside the machine casing on one side of the discharge channel; a motor is provided on the machine casing to drive the cutting tool to rotate; the bottom wall of the discharge channel is recessed to form a first collection trough; the top of the first collection trough is covered with a detachable first screen; the first screen has a first mesh opening for small-diameter fragments to pass through, thereby achieving the purpose of directly classifying the shredded fragments according to their particle size, reducing the time and manpower consumed in screening.

[0004] However, in actual bamboo leaf crushing operations, the cutter head generates a large impact force when crushing bamboo leaves at high speed. This impact force is transmitted to the motor shaft through the cutter head. Over time, this can easily lead to damage to the motor shaft, affecting the normal operation and service life of the motor. At the same time, the motor generates heat during operation. As an important transmission component of the motor, if the motor shaft cannot dissipate heat in time, it will lead to a decrease in motor performance, increased energy consumption, and even motor failure.

[0005] Therefore, this invention proposes a bamboo leaf crushing device with an energy-saving motor to solve the problem that the collision between the blade and bamboo fiber and hard impurities during the existing bamboo leaf crushing process generates instantaneous impact force, which causes sudden changes in the motor shaft torque, forcing the motor to frequently adjust its output power and increasing energy consumption.

[0020] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 Please see Figures 1-17This invention provides a technical solution: a bamboo leaf pulverizing device with an energy-saving motor, comprising a pulverizer mounting base 1, on the upper end of which a three-phase asynchronous energy-saving motor 11 and a bamboo leaf pulverizer 2 are fixedly mounted. A transmission mechanism 12 is fixedly connected to the output shaft of the three-phase asynchronous energy-saving motor 11. The transmission mechanism 12 consists of a driving pulley, a driven pulley, and a belt. The inner surface of the center of the driven pulley is fixedly connected to the outer surface of one end of the motor shaft mechanism 3. The output end of the transmission mechanism 12 is fixedly connected to a motor shaft. The rod mechanism 3 and the bamboo branch and leaf crusher 2 are bolted together with the mounting side plates 21 of the housing. A whole branch feed pipe 22 is fixedly connected to the side of the bamboo branch and leaf crusher 2 closest to the three-phase asynchronous energy-saving motor 11. An auxiliary pressing roller is installed inside the whole branch feed pipe 22. When bamboo branches are inserted through the feed inlet of the whole branch feed pipe 22, the branches are pre-pressed by the auxiliary pressing roller and then enter the space between the bamboo leaf crushing disc mechanism 4 and the inner wall of the bamboo branch and leaf crusher 2, initiating the crushing operation. The upper end of the bamboo branch and leaf crusher 2 is also connected to... The leaf crushing discharge pipe 23 and the motor shaft mechanism 3 have both ends penetrating the inner wall of the mounting side plate 21 of the machine box. A bushing mechanism is provided on the outside of the motor shaft mechanism 3. The bushing mechanism includes a central shaft sleeve 5, heat dissipation fins 51, hollow threaded bolts 52, and a sleeve end tightening unit. A T-shaped interlocking groove 50 is provided on the inner wall of the outer ring of the central shaft sleeve 5. A bamboo leaf crushing cutter disc mechanism 4 is movably installed on the inner side of the T-shaped interlocking groove 50. The bamboo leaf crushing cutter disc mechanism 4 includes a cutter disc body 41, a cutter holder 42, and a cutter disc mounting side plate 43. The cutter disc mounting side plate 43 is fixed. Installed at both ends of the cutter head body 41; a snap-fit ​​square groove 410 is provided on the inner wall of one side of the cutter head body 41; the cutter holder 42 is fixedly connected to the outer surface of one side of the cutter head body 41 by bolts; a material blocking groove is provided on the inner surface of the cutter holder 42; a material blocking partition 422 is fixedly installed on the inner surface of the material blocking groove; a horizontal blade 421 is snap-fitted on the upper side of the material blocking partition 422; and a square insert 4211 is fixedly installed on the outer back side of the horizontal blade 421; the outer surface of the square insert 4211 is movably engaged with the inner wall of the snap-fit ​​square groove 410. In this embodiment, both the cutter head body 41 and the cutter holder 42 are coated with wear-resistant ceramic or polytetrafluoroethylene coatings to reduce bamboo leaf adhesion and frictional wear. When the branches are fed in, air enters along with the material and is subsequently accelerated by the rotor. According to the principles of fluid mechanics, the rotating bamboo leaf crushing cutter head mechanism 4 drives the movement of air molecules, giving the air kinetic energy and forming a high-speed airflow, ultimately causing the crushed bamboo branches and leaves to be thrown out of the discharge port of the leaf discharge pipe 23. Through the optimized design of the bamboo leaf crushing cutter head mechanism 4, the cutter head is made lightweight while maintaining structural strength and reducing rotational inertia. Furthermore, the motor shaft mechanism 3 and the bamboo leaf crushing cutter head mechanism 4 are designed to... The addition of a bushing mechanism can isolate impact loads and reduce motor power fluctuations. Through the cooperation of the central bushing seat 5 and the sleeve end locking unit, after docking and assembly, it can not only form an integral structure with the bamboo leaf crushing disc mechanism 4, but also protect the outside of the motor shaft mechanism 3. In addition, the setting of vibration damping components can absorb and disperse impact energy during crushing, reducing the impact on the motor shaft mechanism 3. Furthermore, the optimization of the structure of the motor shaft mechanism 3 can prevent the motor shaft mechanism 3 from overheating and damaging the motor performance during high-speed operation. It also helps to reduce stress changes caused by thermal expansion and contraction, further improving the efficiency and quality of bamboo leaf crushing. It should be noted that the horizontal blade 421 is movably engaged with the square groove 410 of the cutter head body 41 via the square insert 4211, and the blade holder 42 is fixed to the cutter head body 41 with bolts, so that the connection of each component is firm and can work stably during the crushing operation. Furthermore, the material blocking groove and material blocking partition 422 on the inner side of the blade holder 42, combined with the horizontal blade 421, help to better block the material and carry out the crushing operation during the bamboo leaf crushing process, further improving the efficiency and quality of bamboo leaf crushing.

[0022] Example 2 See attached document Figures 1-17 Based on Embodiment 1, in order to achieve the assembly of the motor shaft mechanism 3 and the central shaft sleeve 5, while integrating the functions of protection, heat dissipation, and airflow guidance into one unit: The outer ring surface of the central shaft sleeve 5 is also provided with a fan-shaped groove 510, and the inner cavity sidewall of the fan-shaped groove 510 is uniformly provided with threaded grooves 5100, which correspond one-to-one with the mating circular holes 300; multiple sets of heat dissipation fins 51 are movably engaged with the inner side of the fan-shaped groove 510, and hollow threaded rods 52 penetrate the inner wall of the heat dissipation fins 51 and extend to the inner wall of the central shaft sleeve 5 for threaded connection. The hollow threaded rods 52 have a hollow cylindrical structure, and the inner ring surface of the central shaft sleeve 5 is movably engaged with the outer surface of the motor shaft mechanism 3, dissipating heat... The hot fins 51 are threaded to the inner wall of the central shaft sleeve 5 via hollow threaded bolts 52; a central oil channel 30 is provided on the central inner wall of the motor shaft mechanism 3, and Archimedes spiral grooves 301 are uniformly provided on the inner ring surface of the central oil channel 30, and an end sealing plug 31 is embedded and installed on the inner wall of the end of the central oil channel 30 away from the transmission mechanism 12; mating round holes 300 are uniformly provided on the inner ring surface of the central oil channel 30, and the mating round holes 300 are axially distributed about the central axis of the motor shaft mechanism 3; In this embodiment, please refer to 5. Figure 11 and Figure 13 As shown, the structure of the motor shaft mechanism 3 is optimized by opening a central oil channel 30 inside it for supplying cooling oil. Here, by adding a central shaft sleeve 5 between the bamboo leaf crushing disc mechanism 4 and the motor shaft mechanism 3, the impact load can be isolated, the motor power fluctuation can be reduced, and the energy consumption can be reduced. It is worth noting that a fan-shaped groove 510 is opened on the outer ring surface of the central shaft sleeve 5 to accommodate the installation of the heat dissipation fins 51. The hollow threaded bolt 52 serves as a fastener for the installation between the multiple sets of heat dissipation fins 51 and the central shaft sleeve 5. The hollow threaded bolt 52 has a hollow cylindrical structure and also serves as a guide for the cooling oil. Specifically, when the cooling oil is injected from the end of the motor shaft mechanism 3 near the end sealing plug 31, the oil fills the inner cavity of the central oil channel 30. The uniform flow of the oil is achieved through the opening of the mating round hole 300. Under high-speed rotation, the cooling oil is discharged from the multiple sets of mating round holes 300 and overflows outward through the central cylinder of the hollow threaded bolt 52, causing the lubricating oil to be thrown towards the inner wall of the cutter head body 41. This achieves auxiliary cooling of the cutter and the motor shaft mechanism 3, preventing the motor shaft mechanism 3 and the cutter from overheating and damaging the motor performance. It also helps to reduce stress changes caused by thermal expansion and contraction.

[0023] Example 3 See attached document Figures 1-17 Based on Embodiment 2, in order to ensure a tight fit between the central shaft sleeve 5 and the motor shaft mechanism 3, and to integrate limiting, installation, and vibration damping functions into one unit: The sleeve end tightening unit includes a central shaft tightening sleeve 53, which is integrally formed from a cylindrical part and a plate-shaped part. The outer surface of the cylindrical part penetrates the central inner wall of the cutter head mounting side plate 43, and the central inner surfaces of the cylindrical part and the plate-shaped part are movably sleeved with the outer surfaces of both ends of the motor shaft mechanism 3. A limit post 531 is fixedly installed on one end of the inner side of the cylindrical part, and a limit circular groove 5310 that is adapted to fit and engage with the outer surface of the limit post 531 is correspondingly opened on the inner walls of both ends of the central shaft sleeve 5. The cutter head body 41 is composed of an engaging part 411 and a mounting part 412, and the cutter head 42 is fixedly installed on the inner side of the mounting part 412. A locking groove 530 is opened on the inner wall of the cylindrical part of the central shaft tightening sleeve 53, and the locking groove 530 is connected with the grooves at both ends of the T-shaped engaging groove 50. The outer surface of the engaging part 411 is respectively engaged with the inner walls of the T-shaped engaging groove 50 and the locking groove 530. In this embodiment, firstly, one set of central shaft locking sleeves 53 and the cutter head mounting side plate 43 are installed with the motor shaft mechanism 3. Then, the central shaft sleeve 5 is inserted from the other end of the motor shaft mechanism 3. At this time, the threaded grooves 5100 correspond to the corresponding mating holes 300. When the central shaft sleeve 5 matches the first set of central shaft locking sleeves 53, the limiting post 531 is precisely embedded in the limiting groove 5310 opened at one end of the central shaft sleeve 5. At this time, the central shaft sleeve 5 is initially limited. The other set of central shaft locking sleeves 53 and the cutter head mounting side plate 43 pass through one end of the motor shaft mechanism 3, and the limiting post 531 is precisely embedded in the limiting groove 5310 at the other end of the central shaft sleeve 5. In this way, the precise positioning of the central shaft sleeve 5 is achieved. Figure 10 As shown, the two sets of central shaft locking sleeves 53 and central shaft sleeve seats 5 are assembled to form a protective structure for the motor shaft mechanism 3. After assembly, the T-shaped interlocking groove 50 and the locking groove 530 are matched to form a clamping groove for the interlocking part 411 of the tool disc body 41. In this way, multiple locking is achieved after the central shaft locking sleeves 53 and central shaft sleeve seats 5 are assembled.

[0024] Example 4 See attached document Figures 1-17 Based on Example 3, in order to reduce the impact on the motor shaft mechanism 3 during the crushing operation: A vibration damping component is provided on the outer side of the central shaft locking sleeve 53. The vibration damping component includes a butterfly toothed ring 1 532 and a butterfly toothed ring 2 533. Both the butterfly toothed ring 1 532 and the butterfly toothed ring 2 533 are sleeved and installed on the outside of the cylindrical part. The side of the butterfly toothed ring 1 532 away from the butterfly toothed ring 2 533 is in movable contact with the outer side of the cutter head mounting side plate 43. The side of the butterfly toothed ring 2 533 away from the cutter head mounting side plate 43 is in movable contact with the inner side of the plate-shaped part. An elastic connector 534 is fixedly connected between the butterfly toothed ring 1 532 and the butterfly toothed ring 2 533. A folded spring piece 5341 is fixedly connected to the inner surface of the elastic connector 534. In this embodiment, a vibration damping component is added between the chassis mounting side plate 21 and the cutter head mounting side plate 43. The first butterfly toothed ring 532 and the second butterfly toothed ring 533 respectively abut against the inner side wall of the chassis mounting side plate 21 and the outer side wall of the cutter head mounting side plate 43. When impacted during crushing, the elastic connector 534 and the folded spring sheet 5341 deform to absorb energy, thereby absorbing and dispersing the impact energy, reducing the impact on the motor shaft mechanism 3, isolating the impact load, and reducing motor power fluctuations.

[0025] The working principle and usage process of this invention: Before the bamboo leaf crushing operation, the assembled cutter disc mechanism 4 is first movably installed inside the T-shaped interlocking groove 50 on the inner wall of the outer ring of the central shaft sleeve 5. The heat dissipation fins 51 are movably snapped into the fan-shaped groove 510 on the outer ring surface of the central shaft sleeve 5. A hollow threaded bolt 52 is used to penetrate the inner wall of the heat dissipation fins 51 and extend to the inner wall of the central shaft sleeve 5 for threaded connection. First, one set of central shaft locking sleeves 53 and cutter disc mounting side plates 43 are installed with the motor shaft mechanism 3. Then, the entire central shaft sleeve 5 is inserted into the other end of the motor shaft mechanism 3, so that the fan-shaped groove is inserted into the central shaft sleeve 5. The threaded grooves 5100 on the inner wall of the fan-shaped groove 510 correspond to the mating round holes 300 on the corresponding motor shaft mechanism 3. When they match the first set of central shaft locking sleeves 53, the limiting post 531 is embedded in the corresponding position opened at one end of the central shaft sleeve 5. The other set of central shaft locking sleeves 53 and the cutter head mounting side plate 43 pass through one end of the motor shaft mechanism 3, and the limiting post 531 is embedded in the other end of the central shaft sleeve 5, so as to achieve precise positioning of the central shaft sleeve 5. At the same time, the T-shaped interlocking groove 50 and the locking groove 530 are matched to form a clamping groove for the interlocking part 411 of the cutter head body, thus completing the assembly. When the cooling oil is injected from the end of the motor shaft mechanism 3 near the end sealing plug 31, the oil fills the inner cavity of the central oil channel 30. Through the opening of the Archimedes spiral groove 301 and the docking round hole 300, the oil is uniformly guided. Under the action of high-speed rotation, the cooling oil is discharged from multiple sets of docking round holes 300 and overflows outward through the central column of the hollow threaded bolt 52, so that the lubricating oil is thrown towards the inner wall of the cutter head 41, thereby achieving auxiliary cooling of the cutting tool and the motor shaft mechanism 3. In actual use, the three-phase asynchronous energy-saving motor 11 is started, and the output shaft drives the active belt pulley of the transmission mechanism 12 to rotate. Through belt transmission, the driven belt pulley rotates, which in turn drives the motor shaft mechanism 3 to rotate, providing power to the bamboo leaf crushing blade mechanism 4. When bamboo leaves are crushed, bamboo leaves and branches are fed into the feed pipe 22 through the feed inlet. After being pre-pressed by the auxiliary pressing roller, they enter the bamboo leaf crushing disc mechanism 4 between the inner wall of the bamboo leaf crusher 2. The rotating bamboo leaf crushing disc mechanism 4 cuts and crushes the bamboo leaves. When the branches are fed in, air enters along with the material and is accelerated by the rotor. According to the principle of fluid mechanics, the rotating bamboo leaf crushing disc mechanism 4 drives the air molecules to move, so that the air gains kinetic energy and forms a high-speed airflow, which throws the crushed bamboo branches and leaves out of the discharge port of the crushed leaf discharge pipe 23.
