In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0021] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0023] Reference Figure 1 to Figure 8 , which is the first embodiment of the present invention, proposes a scrap steel crushing and recycling device for scrap steel crushing, including a shell 1, the shell 1 has a feed port 101, a discharge port 102 and a crushing chamber 103, the feed port 101 and the discharge port 102 are connected to the crushing chamber 103, and the top of the shell 1 also has a mounting port 104; a breaker 2 is rotatably arranged in the crushing chamber 103, and is used to crush the scrap steel; a mounting frame 3 is rotatably arranged on the side wall of the mounting port 104, located above the breaker 2, and the mounting frame 3 has a plurality of mounting grooves 301; a plurality of liner plates 4 are arranged in the mounting grooves 301, and one end of the liner plate 4 is located in the crushing chamber 103, and the breaker 2 hits the scrap steel after rotation, so that the scrap steel contacts the liner plate 4, and after the mounting frame 3 is turned over, the other end of the liner plate 4 is located in the crushing chamber 103.

[0024] In this embodiment, in order to solve the problem that the liner in the hammer crusher in the related art is continuously hit by scrap steel, is easy to wear and needs to be replaced frequently, a scrap steel crushing and recycling device is designed. The shell 1 is designed with a feed port 101, a discharge port 102 and a crushing chamber 103. In the crushing chamber 103, a crushing hammer 2 is installed and connected by a bearing. The mounting frame 3 is rotatably arranged in the crushing chamber 103, and a plurality of mounting grooves 301 are evenly distributed on the mounting frame 3. The liner 4 is made of high-strength wear-resistant steel and is respectively installed in these mounting grooves 301. One end of the liner 4 extends into the crushing chamber 103. When the scrap steel enters the crushing chamber 103 from the feed port 101, the crushing hammer 2 rotates at a high speed to hit and crush the scrap steel. The scrap steel contacts the liner 4 during the crushing process, and the liner 4 plays a role in buffering and protecting the inner wall of the shell 1. When one end of the liner 4 is severely worn, the mounting frame 3 can be rotated to allow the other end of the liner 4 to enter the crushing chamber 103 and continue to work.

[0025] The advantage is that this structural design significantly extends the service life of the liner 4. When one end of the liner 4 is worn out due to long-term impact by scrap steel, there is no need to replace the liner 4 immediately. Simply flip the mounting frame 3 to put the other end of the liner 4 into use, which greatly reduces the frequency of replacing the liner 4. This not only reduces the manpower and material costs required for equipment maintenance, but also greatly shortens the downtime caused by replacing the liner 4, thereby effectively improving the efficiency of crushing and recycling scrap steel.

[0026] Furthermore, the lining plate 4 is slidably arranged in the installation groove 301, and the upper and lower ends of the lining plate 4 respectively have a first overlapping portion 401 and a second overlapping portion 402, and the two sides of the mounting frame 3 respectively have a first overlapping groove 302 and a second overlapping groove 304; the first overlapping portion 401 overlaps with the first overlapping groove 302, and after the mounting frame 3 rotates, the lining plate 4 slides in the installation groove 301 under the action of gravity, so that the second overlapping portion 402 overlaps with the second overlapping groove 304.

[0027] In this embodiment, the lining plate 4 can slide smoothly in the installation groove 301. The first overlapping portion 401 and the second overlapping portion 402 are designed and welded at both ends of the lining plate 4, and the first overlapping groove 302 and the second overlapping groove 304 are processed at the corresponding positions on both sides of the mounting frame 3. When the mounting frame 3 rotates under the action of human or mechanical force, the lining plate 4 slides smoothly in the installation groove 301 under the action of its own gravity, so that the second overlapping portion 402 can overlap with the second overlapping groove 304, thereby realizing the stable switching of the position of the lining plate 4.

[0028] The advantage is that this sliding lap joint structure ensures that the lining plate 4 can quickly and stably switch its working position during the flipping process of the mounting frame 3, enabling the two ends of the lining plate 4 to be reused. At the same time, the automatic sliding lap joint mechanism realized by gravity greatly simplifies the operation process of switching the position of the lining plate 4, improving the automation degree and operation reliability of the equipment.

[0029] Furthermore, the mounting frame 3 includes a frame 5, and both sides of the frame 5 are rotatably arranged on the mounting opening 104. Both sides of the inner wall of the frame 5 are provided with a number of insertion slots 501. A number of first lap joints 302 and second lap joints 304 are both located on the inner wall of the frame 5. The number of partition plates 6 is several, and several partition plates 6 are all arranged in the frame 5. Both ends of the partition plate 6 have insertion parts 601, and several insertion parts 601 are inserted into several insertion slots 501, and an installation slot 301 is formed between adjacent partition plates 6.

[0030] In this embodiment, the mounting frame 3 is composed of a frame 5 and a partition plate 6. The frame 5 is welded by thick steel beams, and a number of equally spaced insertion slots 501 are accurately machined on both sides of the inner wall of the frame 5. The partition plate 6 is made of high-strength steel plates, and the number is determined according to actual needs. Insertion parts 601 that are closely matched with the insertion slots 501 are welded at both ends of each partition plate 6. By inserting the partition plates 6 into the insertion slots 501 of the frame 5 one by one, an installation slot 301 is formed between adjacent partition plates 6.

[0031] The advantage is that the combined structure of the frame 5 and the partition plate 6 greatly enhances the overall strength and stability of the mounting frame 3, enabling it to effectively resist the strong impact force and severe vibration generated during the crushing process, providing reliable protection for the lining plate 4, and ensuring that the lining plate 4 can work normally in a stable environment. In addition, this plug-in installation method of the partition plate 6 has high flexibility and adjustability, facilitating the quick replacement or adjustment of the quantity and layout of the lining plate 4 according to the different specifications of scrap steel and crushing requirements in actual production, significantly improving the versatility and adaptability of the device, optimizing the effect of scrap steel crushing, recycling and reuse, and meeting diverse production needs.

[0032] Furthermore, the frame 5 includes a "C"-shaped frame 502. One side of the "C"-shaped frame 502 has an opening 5021, and the side far from the opening 5021 is rotatably arranged on one side of the mounting opening 104. The inner wall of the side far from the opening 5021 has an insertion slot 501, a first lap joint 302, and a second lap joint 304. A closing plate 503 is arranged at the opening 5021 for closing the opening 5021. The side of the closing plate 503 close to the "C"-shaped frame 502 has an insertion slot 501, a first lap joint 302, and a second lap joint 304, and the other side is rotatably arranged on the other side of the mounting opening 104.

[0033] In this embodiment, the frame 5 is specifically composed of a "C"-shaped frame 502 and a closing plate 503. An opening 5021 is reserved on one side of the "C"-shaped frame 502, and the side far from the opening 5021 can rotate on the installation opening 104. At the same time, the required insertion slots 501, the first overlapping slot 302, and the second overlapping slot 304 are machined on the inner wall of this side. The closing plate 503 is made of a steel plate of the same material as the "C"-shaped frame 502 and is tightly installed at the opening 5021 through bolts. The insertion slots 501, the first overlapping slot 302, and the second overlapping slot 304 are also machined on the side of the closing plate 503 close to the "C"-shaped frame 502. The other side is rotatably connected to the other side of the installation opening 104 through another rotating shaft 10 to ensure the integrity and stability of the entire frame 5.

[0034] The advantage is that this structural design of the "C"-shaped frame 502 and the closing plate 503 greatly facilitates the assembly and daily maintenance work of the mounting frame 3. The existence of the opening 5021 provides a convenient passage for the installation and disassembly of the partition plate 6, facilitating regular inspection, repair, and replacement of the internal components, effectively reducing the difficulty and cost of equipment maintenance, and improving the maintainability and service life of the equipment.

[0035] Furthermore, the two sides of the frame 5 are provided with first through holes 303. The first through holes 303 penetrate through several insertion slots 501. The insertion part 601 is provided with second through holes 602. There are also a number of limiting rods 7. The number of limiting rods 7 is several. The limiting rods 7 penetrate through the first through holes 303 and several second through holes 602 to limit the relative positions of several partition plates 6 and the frame 5.

[0036] In this embodiment, the first through holes 303 are drilled at corresponding positions on the two sides of the frame 5. The diameter of the first through holes 303 is closely matched with the diameter of the limiting rods 7, and the first through holes 303 penetrate through all the insertion slots 501. Second through holes 602 are also drilled at corresponding positions on the insertion part 601 of the partition plate 6. The positions and sizes of the second through holes 602 are adapted to those of the first through holes 303. The limiting rods 7 are made of high-strength alloy steel. The length of the limiting rods 7 is determined according to the size of the frame 5 and the number of partition plates 6. The limiting rods 7 are sequentially passed through the first through holes 303 and the second through holes 602 of all the partition plates 6, so that the positions of the partition plates 6 in the frame 5 are accurately fixed, preventing them from shifting or loosening during the crushing process.

[0037] The advantage is that the setting of the limiting rods 7 effectively solves the problems of displacement and loosening that may occur to the partition plates 6 during the crushing process, ensuring the stability of the installation slot 301 and the normal working state of the lining plate 4. This further improves the reliability and stability of the device, reducing equipment failures and safety hazards caused by component loosening.

[0038] Furthermore, it also includes a cover plate 8, which is rotatably arranged on the shell 1. After the cover plate 8 rotates close to the installation port 104, it abuts against one end of a plurality of liner plates 4 away from the crushing chamber 103, so as to limit the position of the liner plates 4 in the installation groove 301; a swing driving member 9 is arranged on the shell 1, so as to drive the cover plate 8 to rotate.

[0039] In this embodiment, a cover plate 8 made of a thick steel plate is installed on the top of the shell 1. One side of the cover plate 8 is rotatably connected to the shell 1 through a solid hinge, so that it can rotate flexibly. A hydraulic swing drive 9 is installed at a suitable position on the side of the shell 1. The cylinder of the swing drive 9 is hinged to the shell 1 through a pin, and the piston rod end of the swing drive 9 is hinged to the other side of the cover plate 8 through another pin. When the piston rod of the swing drive 9 is extended or retracted, it can drive the cover plate 8 to rotate around the hinge. When the cover plate 8 rotates close to the installation port 104, it can tightly abut against one end of the plurality of liner plates 4 away from the crushing chamber 103, thereby effectively limiting the position of the liner plates 4 in the installation slot 301 and preventing them from accidentally moving during operation.

[0040] The advantage is that the combined use of the cover plate 8 and the swing drive member 9 provides reliable fixation and protection for the non-working end of the liner 4, effectively preventing the liner 4 from accidentally sliding out of the mounting groove 301 due to strong vibration and other factors during the crushing process, thereby greatly improving the safety and stability of the device.

[0041] Furthermore, it also includes a rotating shaft 10, which has two rotating shafts 10, which are respectively arranged on both sides of the mounting frame 3, and the mounting frame 3 is rotatably arranged at the mounting opening 104 through the rotating shaft 10, and the two rotating shafts 10 both extend out of the mounting opening 104; the ratchet 11 is swingably arranged on the rotating shaft 10; the rotating ring 12 is rotatably sleeved on the rotating shaft 10, and the inner wall of the rotating ring 12 has a ratchet ring 1201, and the ratchet ring 1201 cooperates with the ratchet 11 to abut; the two ends of the clockwork spring act on the rotating shaft 10 and the rotating ring 12 respectively. 2, used to provide a force for the rotating ring 12 to rotate and reset on the rotating shaft 10; the two ends of the linkage rope 13 are respectively connected to the cover plate 8 and the rotating ring 12, and are wound around the rotating ring 12; after the swing driving member 9 is retracted, the cover plate 8 is away from the mounting frame 3, so that the rotating ring 12 overcomes the spring spring to rotate and drives the rotating shaft 10 to rotate; after the swing driving member 9 is extended, the cover plate 8 is close to the mounting frame 3, and the spring spring drives the rotating ring 12 to rotate in the opposite direction, so that the linkage rope 13 is wound around the rotating ring 12, and does not drive the rotating shaft 10 to rotate.

[0042] In this embodiment, two rotating shafts 10 are installed on both sides of the mounting frame 3. One end of the rotating shaft 10 is firmly fixed to the mounting frame 3 through a key connection, and the other end extends out of the mounting opening 104 and is installed with a pawl 11 and a rotating ring 12. The pawl 11 is swingably installed on the rotating shaft 10 through a pin and a pawl spring. The rotating ring 12 is made of wear-resistant metal material, and its inner wall is processed with a ratchet ring 1201 matching the pawl 11. One end of the spring spring is fixed to the rotating shaft 10, and the other end is fixed to the rotating ring 12, providing the rotating ring 12 with a rotation reset force. The linkage rope 13 is a high-strength steel wire rope, one end of which is connected to the cover plate 8, and the other end is wound around the rotating ring 12 and fixed. When the swing driving member 9 retracts, the cover plate 8 moves away from the mounting frame 3, pulling the linkage rope 13, so that the rotating ring 12 overcomes the elastic force of the clockwork spring and rotates, thereby driving the rotating shaft 10 to rotate, thereby realizing the flipping of the mounting frame 3; when the swing driving member 9 extends, the cover plate 8 approaches the mounting frame 3, the clockwork spring drives the rotating ring 12 to rotate in the opposite direction, and the linkage rope 13 is wound around the rotating ring 12. At this time, under the interaction of the pawl 11 and the ratchet ring 1201, the rotating shaft 10 does not rotate, and the mounting frame 3 remains stable.

[0043] The advantage is that this ingenious linkage structure design successfully realizes the automatic coordinated control of the flipping action of the cover plate 8 and the mounting frame 3. When the working end of the mounting frame 3 needs to be flipped to replace the lining plate 4, the operator only needs to simply control the swing drive member 9 to retract, and the entire linkage mechanism can automatically complete the flipping operation of the mounting frame 3, without the need for manual flipping, which greatly improves the convenience and safety of operation. At the same time, the clever coordination of the spring and the pawl 11 ensures the stable operation of the rotating ring 12 and the rotating shaft 10 under different working conditions, effectively avoiding equipment failures caused by misoperation or external interference.

[0044] Furthermore, the rotating shaft 10 has an extending portion 1001 , and the rotating ring 12 is rotatably disposed on the extending portion 1001 .

[0045] In this embodiment, an extension portion 1001 having a diameter larger than the main body of the shaft 10 is processed on the shaft 10, and the outer diameter of the rotating ring 12 matches the size of the extension portion 1001. The rotating ring 12 is installed on the extension portion 1001 through a bearing to ensure that the rotating ring 12 can rotate flexibly and smoothly on the extension portion 1001, thereby reducing friction and wear during rotation.

[0046] Furthermore, the rotating ring 12 has an annular groove 1202 , and the annular groove 1202 is used to accommodate the linkage rope 13 .

[0047] In this embodiment, an annular groove 1202 is machined on the outer surface of the rotating ring 12. The depth and width of the annular groove 1202 are precisely designed according to the diameter of the linkage rope 13, so that the linkage rope 13 can be placed exactly in the annular groove 1202, and during the rotation of the rotating ring 12, the linkage rope 13 will not fall out of the annular groove 1202.

[0048] The advantage is that the design of the annular groove 1202 can perfectly fix the position of the linkage rope 13, effectively preventing the linkage rope 13 from being offset, entangled or falling off during the rotation of the rotating ring 12, thereby ensuring the connection stability and transmission efficiency between the linkage rope 13 and the cover plate 8 and the rotating ring 12.

[0049] The invention discloses a method for crushing, recycling and reusing scrap steel, and uses a device for crushing, recycling and reusing scrap steel.

10. A method for crushing and recycling scrap steel, using a scrap steel crushing and recycling device according to any one of claims 1 to 9, characterized in that: S1. The scrap steel to be crushed is fed into the crushing chamber (103) through the feed port (101) of the equipment. The crushing hammer (2) starts to rotate and strikes the scrap steel entering the crushing chamber (103), thereby crushing the scrap steel into smaller particles or fragments. S2. When the lining plate (4) is seriously worn and the crushing effect is affected, the swing driving member (9) is started to retract. The swing driving member (9) drives the cover plate (8) away from the mounting frame (3). At this time, the linkage rope (13) pulls the rotating ring (12) to overcome the resistance of the spring and start to rotate. The rotation of the rotating ring (12) drives the rotating shaft (10) to rotate, thereby realizing the flipping of the mounting frame (3). S3. After the mounting frame (3) is turned over, the liner (4) slides in the mounting groove (301) by its own weight. The first overlapping portion (401) originally overlapping the first overlapping groove (302) is separated, and the second overlapping portion (402) is overlapped with the second overlapping groove (304), so that the other end that was originally unused enters the crushing chamber (103) and replaces the severely worn end to continue the crushing work. S4. After the liner (4) is switched, the swing drive member (9) is controlled to extend, pushing the cover plate (8) close to the mounting frame (3). At this time, the spring drives the rotating ring (12) to rotate in the opposite direction, and the linkage rope (13) is wound in the ring groove (1202) on the surface of the rotating ring (12). Due to the interaction between the ratchet (11) and the ratchet ring (1201) on the inner wall of the rotating ring (12), the rotating shaft (10) no longer rotates, the mounting frame (3) remains stable, and the equipment returns to the normal crushing operation state, and continues to crush the scrap steel.
