[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Please see Figure 1-6As shown, this utility model is a rotary kelp shredder, including a frame assembly, which includes a base plate 10, side plates 11, and support legs 12; a conveyor belt 14, which is installed inside the frame assembly and continuously conveys the kelp to be shredded to the bottom of the rotary cutter body 15 to ensure continuous feeding. Support legs 12 are fixedly installed at the four corners of the bottom end of the base plate 10. There are two sets of side plates 11, which are fixedly installed on both sides of the top of the base plate 10. The conveyor belt 14 is installed between the two sets of side plates 11. A protective cover 16 is installed on the top of the two sets of side plates 11. One end of the protective cover 16 is located above the rotary cutter body 15 to prevent the operator from accidentally touching the rotary cutter body 15. A collection box is provided on one side of the support leg 12, which is located below one end of the conveyor belt 14 and is used to collect kelp shreds. The base plate 10, side plates 11 and support legs 12 are rigidly connected to form an integrated frame structure. The conveyor belt 14 is horizontally installed between the two sets of side plates 11, which can realize continuous and uniform conveying of kelp. Compared with manual feeding, it avoids the problem of uneven shred thickness caused by uneven feeding speed, and improves the consistency of shredding. The collection box is precisely located below the discharge end of the conveyor belt 14, which can directly receive the shredded kelp without the need for additional manual collection, reducing material waste and labor costs, while preventing kelp shreds from scattering and polluting the workshop environment.

[0020] like Figure 2-3 As shown, the roller cutter assembly is used to cut kelp into shreds. The roller cutter assembly includes a roller cutter body 15 and a roller cutter shaft 18. The roller cutter shaft 18 is fixedly connected to the axis of the roller cutter body 15. A bearing 19 is installed on the outer wall of the roller cutter shaft 18. A drive motor 17 is fixedly installed on one side of the outer wall of the side plate 11. A driven wheel is fixedly connected to one end of the roller cutter shaft 18. The output shaft of the drive motor 17 is fixedly connected to a drive wheel through a coupling. A belt is fitted between the drive wheel and the driven wheel, and the drive wheel drives the driven wheel through the belt. A control cabinet 13 is fixedly installed at the bottom of the base plate 10. The control cabinet 13 is equipped with a PLC control program and operation control buttons. By adopting a transmission structure consisting of a drive motor 17, a drive pulley, a belt, a driven pulley, and a roller shaft 18, the belt drive has a buffering and vibration-absorbing effect, which can reduce the impact load on the roller assembly during the start-up of the drive motor 17 and reduce the operating noise of the equipment. The bearing 19 significantly reduces the rotational resistance of the roller shaft 18, reduces the energy consumption of the drive motor 17, and reduces the wear between the roller shaft 18 and the support column 21 and the locking column 22, extending the service life of the roller assembly and reducing the maintenance frequency. A servo motor is installed on one side of the conveyor belt 14. The servo motor is electrically connected to the PLC control program in the control cabinet 13. The servo motor and the drive motor 17 are powered by mains electricity. The speed of the control cabinet 13 and the drive motor 17 is controlled by the PLC control program, and the shredding is automated.

[0021] like Figure 3-6As shown, the mounting assembly includes a support column 21 and a locking column 22. The support column 21 cooperates with the locking column 22 to limit and fix the bearing 19. The support column 21, the locking column 22 and the bearing 19 are in a movable locking relationship. One end of the side plate 11 is provided with a protrusion. The bottom end of the support column 21 is fixedly installed on the top of the corresponding protrusion. A semi-circular groove is opened at the top of the support column 21. A first locking groove 23 is opened at the middle position of the semi-circular groove of the support column 21. A first limiting groove 24 is opened through the first locking groove 23 and the outer walls on both sides of the support column 21. A semi-circular groove is opened at the bottom of the locking column 22. A second locking groove 26 is opened at the middle position of the semi-circular groove of the locking column 22. A second limiting groove 27 is opened through the second locking groove 26 and the outer walls on both sides of the locking column 22. The bearing 19 engages within the corresponding first engagement groove 23 and second engagement groove 26. Symmetrical limiting blocks 20 are fixedly installed on the outer ring of the bearing 19, and these limiting blocks 20 are movably engaged within the corresponding first limiting groove 24 and second limiting groove 27. First fixing seats 25 are fixedly installed on both outer walls of the support column 21, and second fixing seats 28 are fixedly installed on both outer walls of the engagement column 22. The first fixing seats 25 and second fixing seats 28 are fixed together with screws. By precisely matching the first engagement groove 23 and second engagement groove 26 within the semi-circular grooves of the support column 21 and engagement column 22 with the outer ring of the bearing 19, radial positioning of the bearing 19 can be achieved. The engagement of the limiting blocks 20 with the corresponding first limiting groove 24 and second limiting groove 27 prevents rotation or axial displacement of the bearing 19, avoiding problems such as uneven shred thickness and seaweed shred adhesion caused by deflection of the roller shaft 18 and roller body 15, effectively improving shredding accuracy. By using a first fixing seat 25 and a second fixing seat 28 to fix the support column 21 and the locking column 22 with screws, during disassembly, it is only necessary to unscrew the screws between the first fixing seat 25 and the second fixing seat 28 to separate the locking column 22 and remove the hobbing shaft 18 and bearing 19 for maintenance or replacement. Compared with the traditional welded fixing structure, this effectively shortens the maintenance time.

[0022] The implementation principle of this utility model of a rotary kelp shredder is as follows: First, an integrated frame is constructed by rigidly connecting the base plate 10, side plates 11, and support legs 12. The conveyor belt 14 is installed between the two sets of side plates 11. A protective cover 16 is installed on the top of the side plates 11, and a collection box is placed on one side of the support leg 12 below the discharge end of the conveyor belt 14. At the same time, the roller cutter assembly is fixed by the cooperation of the support column 21 and the locking column 22. The roller cutter shaft 18 with the bearing 19 is locked in the first locking groove 23 of the support column 21 and the second locking groove 26 of the locking column 22, so that the limiting block 20 of the bearing 19 is embedded in the first limiting groove 24 and the second limiting groove 27. Then, the first fixing seat 25 and the second fixing seat 28 are fixed with screws to complete the positioning of the roller cutter assembly.

[0023] Secondly, by setting up the control cabinet 13, the parameters are set using the built-in PLC control program; after the mains power is connected, the servo motor drives the conveyor belt 14 to continuously and uniformly transport the kelp to be shredded to below the roller cutter body 15. At the same time, the drive motor 17 drives the roller cutter shaft 18 to rotate through the drive wheel, belt, and driven wheel transmission structure, so that the roller cutter body 15 rotates at high speed to shred the kelp; the shredded kelp is transported to the discharge end by the conveyor belt 14 and falls directly into the collection box below.

[0024] Finally, when it is necessary to maintain the bearing 19 or replace the hob body 15, unscrew the screws between the first fixed seat 25 and the second fixed seat 28, separate the locking column 22, and then take out the hob shaft 18 and the matching bearing 19 and hob body 15 for maintenance; after maintenance, reset and fix the components according to the initial assembly method to ensure that the equipment is restored to a precise operating state.

[0025] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
