Description

Technical Field

[0001] This utility model belongs to the field of waste treatment, specifically relating to a shredding device suitable for processing steel strip edge wires and a steel strip edge wire processing system using the shredding device. Background Technology

[0002] In various strip steel processing units such as pickling units, pickling and rolling units, galvanizing units, continuous annealing units, and recoiling units, the edge wires after the disc shearing are usually processed by edge chipping or waste edge winding. The former often leads to edge blockage due to the varying width and rigidity of the edge wires; the latter requires manual guide of the strip head into the core each time, which is extremely dangerous for workers and occupies operators for a long time.

[0003] Patent CN209578327U discloses a strip steel edge wire processing device, which uses a shredder to process the strip steel edge wire. It achieves good shredding results, can adapt to edge wires of various widths and rigidities, and avoids the edge clogging problems common with edge shears. Furthermore, it can process automatically, achieving safe and unattended operation. However, in actual operation, it is easy for the strip steel edge wire to enter the shredder vertically, causing it to fall and escape between the cutter shafts, resulting in a certain proportion of long waste material in the shredded material, affecting subsequent recycling. Utility Model Content

[0004] This utility model relates to a shredding device suitable for processing steel strip edge wires and a steel strip edge wire processing system using the shredding device, which can at least solve some of the defects of the prior art.

[0005] This utility model relates to a shredding device suitable for processing steel strip wires, including a shredder, with a diversion column provided directly above the shearing zone of the shredder.

[0006] As one implementation method, the length direction of the diversion column is parallel to the axial direction of the shredder's cutter shaft.

[0007] As one implementation method, multiple diversion columns are arranged side by side directly above the shearing zone and / or multiple diversion columns are arranged in staggered layers.

[0008] As one implementation method, the cross-sectional shape of the diversion column is a cone shape that is narrower at the top and wider at the bottom, a hemispherical shape that is narrower at the top and wider at the bottom, or a cylinder shape.

[0009] As one implementation method, the diversion column adopts a hollow column structure.

[0010] As one implementation method, the diversion column is a high-strength wear-resistant steel column.

[0011] As one implementation method, when the shredder has multiple shearing zones, the diversion column is provided directly above each shearing zone.

[0012] As one embodiment, the shredder is provided with a feed chute at the material inlet, and the diversion column is installed in the feed chute.

[0013] As one implementation method, the diversion column can be detachably installed inside the feed chute.

[0014] This utility model also provides a strip edge wire processing system, including a shredder arranged below the strip edge cutting device and a material guiding mechanism for guiding the strip edge wire from the strip edge cutting device to the shredder, wherein the shredder adopts the shredding device described above.

[0015] This utility model has at least the following beneficial effects:

[0016] This invention features a diversion column above the shredder. Before falling into the shredder, the long strip steel wires first come into contact with the diversion column, which forces them to deflect to one or both sides, reducing the likelihood of them entering the shredder vertically and falling between the cutter shafts. This reduces the proportion of long waste material and ensures shredding effect. Furthermore, it disperses the material, making the steel wires more evenly distributed across the entire working surface of the shredder cutter shafts, thereby improving the processing effect and efficiency of the steel wires.

[0017] The diverter column pre-bends and initially twists the strip wires, disrupting their rigidity and straight shape. When this now-bent wire comes into contact with the shredder's cutter shaft, it can be quickly pulled in and sheared by multiple cutters, instead of being completely wrapped around the shaft like a straight rod. Furthermore, the diverter column reduces the direct impact of the strip wires on the cutter shaft, significantly reducing the impact load on the shredder. Attached Figure Description

[0031] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] Example 1

[0033] like Figure 1 and Figure 2This utility model provides a strip steel edge wire processing system, including an edge-shredding device arranged below a strip steel edge-cutting device and a material guiding mechanism 20 for guiding the strip steel edge wire from the strip steel edge-cutting device to the edge-shredding device. The edge-shredding device includes an upper shredder 11 and a lower shredder 12 arranged below the upper shredder 11. The material inlet of the upper shredder 11 is connected to the material guiding mechanism 20, and the material inlet of the lower shredder 12 is connected to the material outlet of the upper shredder 11.

[0034] In the above scheme, the strip edge wires formed after the strip is cut are guided to the edge-shredding device by the material guiding mechanism 20. The edge-shredding device shreds the strip edge wires into edge pieces of a certain length. The edge-shredding device uses a shredder, which has a good shredding effect, stable and reliable operation, and can adapt to edge wires of various widths and rigidities. It avoids the edge-clogging failure that is common with edge-shredding shears, and can automatically process the material, achieving safe and automatic operation without human intervention, ensuring production safety and reducing labor intensity.

[0035] For ease of description, the cutter shaft of the upper shredder 11 is defined as the upper cutter shaft, and the cutter shaft of the lower shredder 12 is defined as the lower cutter shaft.

[0036] The upper-level shredder 11 can be a single-shaft, dual-shaft, or multi-shaft (generally three-shaft or four-shaft) shredder. All upper-level cutter shafts rotate via a drive device. Preferably, the transmission speed of the upper-level shredder 11 is adjustable and matches the main line speed of the strip processing unit to meet the processing requirements of strip edge wire generated during normal unit operation. The upper-level drive device 111 includes, but is not limited to, a motor + transmission structure; preferably, each upper-level cutter shaft is driven independently, such as... Figure 1 When a twin-shaft shredder is used, two sets of upper drive devices 111 are configured to drive the two upper cutter shafts respectively. The two sets of upper drive devices 111 are preferably located on both sides of the upper shredder 11, which facilitates the arrangement of the equipment.

[0037] The lower-level shredder 12 can be a single-shaft, dual-shaft, or multi-shaft (generally three-shaft or four-shaft) shredder. All lower-level cutter shafts rotate via a drive device. Preferably, the transmission speed of the lower-level shredder 12 is adjustable, which can improve the system's operational flexibility and reliability. The lower-level drive device 121 includes, but is not limited to, a motor + transmission structure; preferably, each lower-level cutter shaft is driven independently, such as... Figure 1 When a twin-shaft shredder is used, two sets of lower drive devices 121 are configured to drive the two lower cutter shafts respectively. The two sets of lower drive devices 121 are preferably located on both sides of the upper shredder 11, which facilitates the arrangement of the equipment.

[0038] In one embodiment, the upper shredder 11 is a three-shaft or four-shaft shredder, and the lower shredder 12 is a two-shaft shredder. This arrangement not only results in smaller, denser, and more uniform shredded waste particles, but also provides excellent anti-winding capabilities, ensuring effective treatment of steel strip edges and improving the operational reliability of the shredding device. Furthermore, this arrangement allows for a certain degree of misalignment between the cutter shafts of the lower shredder 12 and the upper shredder 11. This design offers the following advantages:

[0039] (1) It can avoid the formation of material bridges or vertical blockages between the two layers of shredders, greatly reducing the risk of material blockage;

[0040] (2) The waste generated by the upper shredder 11 usually impacts the side of the cutter disc or the cutter roller of the lower cutter shaft. This impact process itself is a pre-positioning and secondary crushing process, which can make the waste better fed into the shear gap instead of being stuck straight in, thus making the shredding action more effective.

[0041] (3) The material impact points are dispersed to a larger range or even the entire length of the lower blades, which makes the wear of the blades and bearings more uniform, significantly extending the service life of the entire set of blades and the maintenance cycle of the equipment, and also avoiding the situation where the same part of the lower blades is continuously subjected to concentrated impact and instantaneous overload.

[0042] In one embodiment, the upper shredder 11 has fewer blades than the lower shredder 12. The upper shredder 11 features a wide blade spacing and thick blades, providing durability and anti-tangling properties, and can pre-shred the steel strip edges. The lower shredder 12 features a narrow blade spacing and multiple blades, allowing for further fine shredding of the steel strip edges. Optionally, the upper shredder 11 quickly breaks the steel strip edges into 50-100mm long fragments, while the lower shredder 12 further shears the material from the upper shredder 11 into 10-30mm shredded waste.

[0043] Preferably, such as Figure 1 and Figure 2 The lower shredder 12 is located directly below the upper shredder 11, facilitating the entry of material from the upper shredder 11 into the lower shredder 12. In another optional embodiment, the lower shredder 12 can also be located diagonally below the upper shredder 11, with an intermediate guide unit reliably guiding the material from the upper shredder 11 into the lower shredder 12. Of course, when the lower shredder 12 is directly below the upper shredder 11, the two can be connected by an intermediate guide unit to prevent material from escaping. Therefore, as... Figure 1 and Figure 2Preferably, the upper shredder 11 and the lower shredder 12 are connected via an intermediate feeding unit. This intermediate feeding unit can be a chute or similar structure to achieve closed feeding. Taking the intermediate feeding unit as an intermediate chute 132 as an example, the intermediate chute 132 is preferably detachably connected to both the upper shredder 11 and the lower shredder 12 for easy inspection and maintenance. Generally, threaded fasteners can be used to achieve this detachable connection, which will not be elaborated here. The intermediate chute 132 preferably has a structure with a wide inlet and a narrow outlet, which facilitates the flow of materials and their convergence to the cutter shaft area of ​​the lower shredder 12.

[0044] In one embodiment, such as Figure 1 The upper shredder 11 and the lower shredder 12 are arranged in parallel, specifically, the axis of the upper cutter shaft is parallel to the axis of the lower cutter shaft.

[0045] In another embodiment, the upper shredder 11 and the lower shredder 12 are not arranged in parallel, that is, there is an angle greater than 0° between the axis of the upper cutter shaft and the axis of the lower cutter shaft; Figure 2 In the illustrated scheme, the axis of the upper cutter shaft is perpendicular to the axis of the lower cutter shaft. The significance of this design is that after the edge shredder 11 shreds the material, some longer pieces may remain. When these longer pieces fall to the lower shredder 12, they tend to lie flat along a direction perpendicular to the axis of the upper cutter shaft. In the parallel arrangement of the upper and lower shredders 11, the surface of the waste received by the lower shredder 12 may be perpendicular to the axis of the cutter shaft, easily causing the waste to leak down the blades and escape. However, when the upper and lower shredders 11 are not arranged parallel, especially when the axes of the upper and lower cutter shafts are perpendicular, the longer pieces of waste generated by the upper shredder 11 are more easily caught by the cutter shaft of the lower shredder 12, thus effectively reducing the escape rate of the longer waste.

[0046] In the above scheme, the axis of the upper tool shaft and the axis of the lower tool shaft have an angle greater than 0°. In particular, the projection of the axis of the upper tool shaft onto the horizontal plane and the projection of the axis of the lower tool shaft onto the horizontal plane are not parallel and have an angle greater than 0°.

[0047] Preferably, such as Figure 1 and Figure 2 The upper shredder 11 has an upper chute 131 at its material inlet. This upper chute 131 is connected to the material guiding mechanism 20 to achieve closed material guiding and prevent edge filaments from escaping. The upper chute 131 and the material guiding mechanism 20 are preferably detachably connected for easy inspection and maintenance. Generally, threaded fasteners or similar materials can be used to achieve the detachable connection, which will not be elaborated here.

[0048] Preferably, such as Figure 1 and Figure 2 The lower shredder 12 has a lower chute 133 at its material outlet, which can discharge and recycle the shredded waste. A waste hopper can be installed below the outlet of the lower chute 133 to collect the shredded waste; or a conveyor belt can be installed below the outlet of the lower chute 133 to transport the shredded waste away.

[0049] Furthermore, in the case where a conveyor belt is installed below the lower chute 133, since the waste material has a high velocity when falling, it is prone to bouncing and splashing off the conveyor belt when it hits the belt. Therefore, a splash guard can be installed next to the conveyor belt, opposite the outlet of the lower chute 133, to block the bouncing waste material. Soft materials, including but not limited to rubber, can be applied to the blocking surface of the splash guard to absorb the kinetic energy of the waste material and prevent secondary splashing.

[0050] Because the double-layer shredder is relatively high and has a large drop, the waste material will generate a large speed during the shredding process, resulting in a loud impact noise when the shredded waste falls onto the lower chute 133. To address this problem, preferably, as follows: Figure 3 A vibration damping plate 1331 is installed on the back of the lower chute 133 to reduce the vibration of the lower chute 133 and achieve the purpose of noise reduction. The vibration damping plate 1331 includes, but is not limited to, rubber plates.

[0051] Example 2

[0052] This embodiment provides a shredding device, including a shredder 10, which is mounted on a frame 30. Preferably, the shredder 10 is movably mounted on the frame 30, such that the shredder 10 has a working position and a maintenance position.

[0053] In one embodiment, such as Figure 4 and Figure 5 A slide rail 301 is provided on the frame 30, and the shredder 10 is slidably mounted on the slide rail 301. The slide rail 301 extends from the working position to the maintenance position, thereby meeting the needs of the shredder 10 to move between the working position and the maintenance position. The shredder 10 can be configured using either a pulley 103-slide rail 301 system or a slider-slide rail 301 system, with corresponding sliding components provided on the shredder 10.

[0054] Furthermore, a limiting part is provided on the sliding part, which cooperates with the edge of the slide rail 301 to prevent the shredder 10 from derailing during movement. For example, a wheel rim is provided on the pulley 103 to form the aforementioned limiting part.

[0055] Optionally, the guide direction of the slide rail 301 is perpendicular to the axis of the cutter shaft of the shredder 10, which facilitates the spatial arrangement of the equipment.

[0056] The aforementioned shredder 10 can be a dual-shaft or multi-shaft shredder, comprising a blade box 101 and multiple blade shafts (≥2) disposed within the blade box 101; each blade shaft rotates via a drive device 102, which includes, but is not limited to, a motor + transmission structure; preferably, each blade shaft is driven independently, such as... Figure 4 When a twin-shaft shredder is used, two sets of drive units 102 are configured to drive the two cutter shafts respectively. The two sets of drive units 102 are preferably located on both sides of the cutter box 101, which facilitates the arrangement of the equipment.

[0057] When the above-mentioned shredding device is used for strip edge wire processing, preferably, the transmission speed of the shredder 10 is adjustable and matched with the main line speed of the strip processing unit to meet the processing requirements of the strip edge wire generated during normal operation of the unit.

[0058] In this embodiment, the blade housing 101 and the drive unit 102 can be integrally slidably mounted on the slide rail 301. In another preferred embodiment, only the blade housing 101 is slidably mounted on the slide rail 301, with the aforementioned sliding components correspondingly mounted on the blade housing 101. The drive unit 102 is mounted on the frame 30 and is detachably connected to the blade shaft. During maintenance, only the blade housing 101 can be driven to slide along the slide rail 301, allowing maintenance only on the easily worn shredder 10, thus reducing maintenance difficulty and costs. The connection method between the drive unit 102 and the blade shaft includes, but is not limited to, a hollow shaft direct connection, a drum-tooth connection, a belt, or a chain drive.

[0059] like Figure 4 and Figure 5 After the toolbox 101 is moved to the maintenance position, it can be lifted away; and the maintained toolbox 101 can be lifted to the maintenance position and then moved into the working position, which can reduce the difficulty of maintenance and increase the speed of maintenance.

[0060] The movement of the tool box 101 can be achieved manually or through a drive device, such as a hydraulic cylinder or an electric push rod.

[0061] Taking the movement of the tool box 101 as an example, when the sliding part uses pulleys 103, it is preferable to provide two pulleys 103 at each end of the tool box 101, which makes the movement of the tool box 101 smoother and more stable. The slide rail 301 mentioned above includes two tracks. In one embodiment, such as... Figure 6Two grooves are provided on each track, located below the pulley 103 at the working position. Each groove includes an arc segment 3011 and a straight segment 3012. The straight segment 3012 is located on the side of the arc segment 3011 closer to the maintenance position, with the center of the arc segment 3011 located above it. The arc segment 3011 is slightly concave to form the groove. Based on this design, the tool box 101 has good stability when in the working position, and the arc segment 3011 facilitates quick and accurate positioning of the tool box 101. When the tool box 101 moves out of the working position, the pulley 103 rises along the straight segment 3012, making the removal of the tool box 101 smoother.

[0062] The shredding device provided in this embodiment can be applied to the above-described embodiment one, serving as the upper shredder 11 and / or the lower shredder 12. That is, the upper shredder 11 adopts the aforementioned shredding device, and / or the lower shredder 12 adopts the aforementioned shredding device. Based on this mobile shredder configuration, the installation and maintenance of the upper shredder 11 / lower shredder 12 can be facilitated, avoiding interference from the material guiding mechanism 20, etc.

[0063] Example 3

[0064] This embodiment provides a shredding device, including a shredder 10, with a material guiding mechanism 20 connected above the shredder 10, wherein, as... Figure 7 The shredder 10 is arranged at an angle, that is, the cutter shaft axis of the shredder 10 has an angle greater than 0° and less than 90° with the horizontal plane.

[0065] When the above-mentioned shredding device is applied to the processing of strip steel edge wire, the long waste material conveyed by the material guiding mechanism 20 is prone to having a surface perpendicular to the axis of the cutter shaft. This can easily cause the waste material to leak down the blades and escape. However, in the above-mentioned scheme of tilting the shredder 10, the long waste material conveyed by the material guiding mechanism 20 is easily captured by the cutter shaft of the shredder 10, thus effectively reducing the escape rate of long waste material.

[0066] More preferably, the angle between the blade shaft axis of the shredder 10 and the horizontal plane is designed to be in the range of 20° to 45°, which has a good anti-escape effect and ensures the processing efficiency of the shredder 10.

[0067] The shredding device provided in this embodiment can be applied to the above embodiment 1 as the upper shredder 11 and / or the lower shredder 12, that is, the upper shredder 11 adopts the above-mentioned shredding device, and / or the lower shredder 12 adopts the above-mentioned shredding device.

[0068] In particular, when combined with the structure in Embodiment 1 involving a non-parallel arrangement between the upper shredder 11 and the lower shredder 12, the escape rate of long waste materials can be further reduced.

[0069] Example 4

[0070] This embodiment provides a shredding device, including a shredder 10, and further, as shown in the following example. Figure 8 and Figure 9 A diversion column 14 is provided above the shredder 10.

[0071] By setting a diversion column 14 above the shredder 10, the long strip steel wires will first come into contact with the diversion column 14 before falling into the shredder 10. The diversion column 14 will force the strip steel wires to deflect to one side or both sides, reducing the possibility of the strip steel wires entering the shredder 10 vertically, reducing the possibility of the wires falling between the cutter shafts, thereby reducing the proportion of long waste and ensuring the shredding effect; and it can also disperse the material, so that the strip steel wires are more evenly distributed on the entire working surface of the cutter shaft of the shredder 10, thereby improving the processing effect and efficiency of the strip steel wires.

[0072] The aforementioned diversion column 14 can pre-bend and initially twist the strip steel edge wires, disrupting their rigidity and straight shape. When this now-bent edge wire comes into contact with the shredder 10's cutter shaft, it can be quickly pulled in and sheared by multiple cutters, instead of being completely wrapped around the shaft like a straight rod. In addition, the aforementioned diversion column 14 also reduces the occurrence of strip steel edge wires directly hitting the cutter shaft, greatly reducing the impact load on the shredder 10.

[0073] A diversion column 14 is set above the shredder 10, which has a simple structure and low manufacturing and installation costs.

[0074] In one embodiment, the length direction of the diversion column 14 is parallel to the axial direction of the cutter shaft of the shredder 10, which can achieve better material distribution and buffering effect.

[0075] Furthermore, such as Figure 8 The aforementioned diversion column 14 is positioned directly above the shearing zone (the area between adjacent cutter shafts) of the shredder 10, thereby achieving better material distribution. When using a three-shaft or four-shaft shredder 10, it is preferable to provide a diversion column 14 in each shearing zone.

[0076] Optionally, multiple diversion columns 14 can be arranged side by side above the shredder 10 and / or multiple diversion columns 14 can be arranged in staggered layers to achieve better material distribution and buffering effect.

[0077] Preferably, such as Figure 8 and Figure 9The shredder 10 is provided with a feed chute 130 at the material inlet, and the aforementioned diversion column 14 is installed in the feed chute 130. This method facilitates the installation of the diversion column 14, and the feed chute 130 can reliably guide the strip steel edge wires that are offset to one or both sides of the diversion column 14 into the shredder 10, ensuring the processing effect.

[0078] Furthermore, the diversion column 14 is detachably installed within the feed chute 130, facilitating the replacement and maintenance of this vulnerable component. Optionally, such as... Figure 9 Holes are drilled at both ends of the feed chute 130, and diverting columns 14 are inserted therein. A detachable connection between the diverting columns 14 and the feed chute 130 can be achieved using methods such as flange locking. The diverting columns 14 can be easily replaced and maintained by pulling them out. Furthermore, the diverting surface of the diverting column 14 can be replaced by rotating it, thus extending its service life.

[0079] The cross-sectional shape of the aforementioned diversion column 14 includes, but is not limited to, a cone (narrower at the top and wider at the bottom), a hemispherical shape (narrower at the top and wider at the bottom), or a simple cylindrical shape, which can reliably guide the edge wires to slide smoothly to both sides.

[0080] Optionally, the aforementioned diversion column 14 can be a hollow column structure, which can reduce the weight accordingly.

[0081] The aforementioned diversion column 14 is preferably made of high-strength wear-resistant steel (such as alloy steel), and can be further hardened to withstand the continuous impact and friction of the strip steel wire.

[0082] like Figure 10 The shredding device provided in this embodiment can be applied to the above embodiment 1 as the upper shredder 11 and / or the lower shredder 12, that is, the upper shredder 11 adopts the above shredding device, and / or the lower shredder 12 adopts the above shredding device.

[0083] When the upper shredder 11 adopts the above-mentioned shredding device, it is preferable to provide a diversion column 14 in the upper chute 131; when the lower shredder 12 adopts the above-mentioned shredding device, it is preferable to provide a diversion column 14 in the middle chute 132.

[0084] Example 5

[0085] This embodiment provides a shredding device, including a shredder 10, and further, as shown in the following example. Figure 11 and Figure 12 The shredder 10 is equipped with a material feeding assembly above it for pushing down the upright materials.

[0086] By setting a material feeding component above the shredder 10 to push down the upright material, the possibility of material falling and escaping between the cutter shafts can be greatly reduced, thereby reducing the proportion of long waste and ensuring the shredding effect.

[0087] In one embodiment, such as Figure 11 The aforementioned feeding assembly is positioned directly above the shearing zone (the area between adjacent cutter shafts) of the shredder 10, thus ensuring the effective feeding of the material. When using a three- or four-shaft shredder, it is preferable to provide a feeding assembly in each shearing zone.

[0088] In one embodiment, such as Figure 11 and Figure 12 The aforementioned material feeding assembly includes a movable rod 151, a plurality of forks 152 disposed on the movable rod 151, and a material feeding drive unit 153 for driving the movable rod 151 to reciprocate along its own length direction. The length direction of the movable rod 151 is parallel to the axial direction of the cutter shaft of the shredder 10. The plurality of forks 152 are disposed at the bottom of the movable rod 151 along its length direction. By driving the movable rod 151 to reciprocate along its own length direction through the material feeding drive unit 153, the forks 152 can be driven to reciprocate along the length direction of the movable rod 151, thereby achieving the purpose of pushing down the upright material.

[0089] Preferably, such as Figure 11 and Figure 12 The shredder 10 has a feed chute 130 above it, and the aforementioned feeding assembly is installed inside the feed chute 130. This method facilitates the installation of the feeding assembly. In the case where the feeding assembly includes a movable rod 151 and multiple forks 152, that is, the movable rod 151 is installed inside the feed chute 130 and can move relative to the feed chute 130, for example, a guide rail is provided on the feed chute 130, allowing the movable rod 151 to be movably positioned on the guide rail to meet the requirement of reciprocating motion of the movable rod 151 along its own length. It is understandable that placing the feeding drive unit 153 outside the feed chute 130 is a better choice.

[0090] The aforementioned material feeding drive unit 153 includes, but is not limited to, driving methods such as motor + crank rocker, and can also be driven by direct drive such as hydraulic cylinder / pneumatic cylinder / electric push rod.

[0091] In one embodiment, such as Figure 11 The aforementioned shift fork 152 adopts a plate structure, and its plate surface is preferably perpendicular to the length direction of the movable rod 151. The plate shift fork 152 can reliably push over the vertical material.

[0092] Furthermore, such as Figure 11The plate-type shift fork 152 adopts an isosceles triangular plate or an isosceles trapezoidal plate that is narrow at the top and wide at the bottom. While ensuring reliable pushing of upright materials, it can reduce the weight of the shifting component. The symmetrical structure of the isosceles triangular plate or the isosceles trapezoidal plate can also ensure the stability of the shift fork 152's movement.

[0093] Furthermore, the aforementioned plate-type shift fork 152 includes a fixed plate and a detachable plate detachably mounted on the fixed plate. By periodically or irregularly replacing the detachable plate, the service life of the shift fork 152 can be effectively extended, reducing maintenance and costs. The fixed plate is mounted on the movable rod 151 and is preferably made of high-strength wear-resistant steel to ensure its service life.
