Description

Technical Field

[0002] The main sources of metal scrap include processing waste (shavings and scrap generated during machining), end-of-life products (metal parts from dismantled equipment and scrapped vehicles), and social recycling (recycled scrap metal products). Processing waste and scrap metal products are mostly soft materials like scrap plates and metal cables, while end-of-life products are mostly large, hard metal blocks.

[0003] The method of recycling metal scrap is mostly to crush the metal scrap through a crusher and then screen it to achieve resource recovery and harmless utilization. High torque is required for shredding soft metal scrap plates and metal cables, while high-speed impact crushing is required for larger hard metal blocks.

[0036] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] Embodiment, according to Figures 1-10 ,like Figure 1-Figure 3 As shown, a metal waste recycling and recovery device provided by an embodiment of the present invention includes a metal recovery cabin 1, a feed port is provided on the top of the metal recovery cabin 1 to guide the flow toward the middle, so that the material can fall into the crushing area, and high-strength lining plates are fixedly installed on the left and right end walls of the metal recovery cabin 1. In order to improve the wear resistance and service life of the cabin body, two roller cores 2 with changeable crushing forms are arranged in mirror images on the left and right sides of the metal recovery cabin 1. Two slots for the axis translation of the roller core 2 are provided at the front and rear ends of the metal recovery cabin 1, so that the distance can be adjusted after the roller core 2 changes the crushing form. A roller sleeve 201 is fixedly installed cocentrically on the roller core 2. The shaft of the roller core 2 is hollow for the circulation of hydraulic oil. A hydraulic controller 101 connected to the shaft of the roller core 2 is fixedly installed on the back of the metal recovery cabin 1. It also includes multiple crushing components 3 installed on the roller core 2. The crushing components 3 have dual crushing modes of tooth crushing and hammer crushing. By switching the crushing modes, different metal scraps can be crushed and recycled. A distance adjustment component 4 is installed on the back of the metal recovery cabin 1 to adjust the distance between the two roller cores 2 to meet the needs of different crushing particle sizes. A speed change component 5 is installed on the back of the metal recovery cabin 1 to adjust the rotation speed of the two roller cores 2 to optimize crushing efficiency and energy consumption.

[0039] like Figure 3-Figure 5As shown, the crushing assembly 3 includes a crushing disc 301 and a hydraulic diverter seat 302. The crushing disc 301 and the hydraulic diverter seat 302 are both provided with multiple and fixedly installed at intervals along the axis of the roller core 2. The axial surface of the roller core 2 is provided with multiple hydraulic through holes corresponding to the hydraulic diverter seat 302. The outer circular edge of the crushing disc 301 is slidably plugged with a tooth head 304 in an annular array. The hydraulic diverter seat 302 is fixedly installed with multiple first hydraulic telescopic rods 306 and second hydraulic telescopic rods 308 in an annular array. The movable end of the first hydraulic telescopic rod 306 is rotatably installed with a swing hammer head 307. In the middle, it is normally in the tooth breaking state, that is, the first hydraulic telescopic rod 306 and the second hydraulic telescopic rod 308 are in the retracted state. Under the limiting effect of the rotating drive disk 303 and the connecting rod 309 on the first protrusion 305, the tooth head 304 keeps extending out of the crushing disk 301, and the swing hammer head 307 is in the retracted state and flush with the outer surface of the roller sleeve 201 to avoid interference with the tooth breaking. The two roller cores 2 rotate in opposite directions, and the tooth heads 304 on the two roller cores 2 are staggered. When recycling soft metal scrap plates or metal cables, they can generate tearing force to tear them into pieces.

[0040] like Figure 6 and Figure 7 As shown, both ends of the crushing disk 301 are rotatably installed with a rotating drive disk 303, and both ends of the tooth head 304 are provided with a first boss 305. The rotating drive disk 303 is provided with an inclined groove corresponding to the first boss 305 to enable the rotating drive disk 303 to rotate forward and reverse and drive the tooth head 304 to move up and down. A connecting rod 309 is rotatably connected between the movable end of the second hydraulic telescopic rod 308 and the rotating drive disk 303. When the swing hammer head 307 is extended, the second hydraulic telescopic rod 308 extends and drives the tooth head 304 to retract and store. A plurality of first receiving holes and second receiving holes are provided on the roller sleeve 201 corresponding to the tooth head 304 and the swing hammer head 307. The first receiving holes and the second receiving holes on the roller sleeve 201 are arranged at intervals. When hammer crushing is required, the hydraulic controller 101 changes the oil supply state, and the first hydraulic The telescopic rod 306 extends, driving the swinging hammer head 307 to swing outward, so that it protrudes from the surface of the roller sleeve 201, forming a rotating hammering structure. At the same time, the second hydraulic telescopic rod 308 also extends, pushing the rotating drive disk 303 to rotate through the connecting rod 309. The rotation of the rotating drive disk 303 uses the inclined grooves on the rotating drive disk 303 to drive the first protrusions 305 at both ends of the tooth heads 304, so that all the tooth heads 304 are retracted downward into the crushing disk 301 and stored to avoid breakage or damage during the hammering process. The retracted tooth heads 304 are stored in the first storage holes corresponding to the roller sleeve 201. The first storage holes and the second storage holes on the roller sleeve 201 are set at intervals to ensure that the two do not interfere with each other during storage and operation, thereby achieving crushing and recovery of larger hard metal blocks.

[0041] like Figure 8As shown, the pitch adjustment assembly 4 includes a pitch adjustment slide 401, an adjustment seat 402 and a transmission shaft 403. The pitch adjustment slide 401 is provided with two and symmetrically slidably mounted on the back of the metal recovery cabin 1. A two-way hydraulic rod 102 is fixedly mounted on the back of the metal recovery cabin 1 to drive the pitch adjustment slide 401 to translate. The two-way hydraulic rod 102 is fixedly connected to the hydraulic controller 101 and linked to the shaft hydraulic transmission of the roller core 2. The adjustment seat 402 is fixedly mounted on the top of the pitch adjustment slide 401. A plurality of fixing screw holes are equidistantly opened on the top of the pitch adjustment slide 401 to adjust the fixed position of the two roller cores 2. A fixed spacing is formed to meet the needs of different crushing particle sizes. A shaft seat 404 is integrally formed on the adjustment seat 402, and a rotary connector 405 is fixedly installed on the shaft seat 404. One end of the roller core 2 passes through the shaft seat 404 and is connected to the rotary connector 405. One end of the shaft of the roller core 2 is fixedly sleeved with a driven bevel gear 202. A protruding shaft frame is integrally formed on the shaft seat 404, and an active bevel gear 406 engaged with the driven bevel gear 202 is rotatably installed on the shaft frame. The transmission shaft 403 is rotatably installed on the metal recovery cabin 1 and the two shaft frames are sleeved on the transmission shaft 403. On the transmission shaft 403, there is a convex strip on the adjustment seat 402 to drive the shaft of the roller core 2 to rotate when the adjustment seat 402 is horizontally displaced. When the tooth crushing mode and the hammer crushing mode are switched, due to the different lengths of the tooth head 304 and the swing hammer head 307, the spacing between the two roller cores 2 needs to be adjusted. Therefore, the two adjustment seats 402 are driven to move horizontally by the bidirectional hydraulic rod 102 linked to the oil circuit in the roller core 2 shaft. In the normal tooth crushing mode, the bidirectional hydraulic rod 102 is in a retracted state, and the transmission shaft 403 rotates through the two active bevel gears 406 and the two driven bevel gears 2 The meshing action of 02 drives the two roller cores 2 to rotate toward the middle. When switching to the hammer crushing mode, the bidirectional hydraulic rod 102 links the first hydraulic telescopic rod 306 and the second hydraulic telescopic rod 308 to extend, and the two adjustment seats 402 move away from each other, driving the two roller cores 2 away from each other to adapt to the hammer crushing requirements of the long swing hammer head 307. It is worth noting that the active bevel gear 406 and the driven bevel gear 202 are installed on the adjustment seat 402, and the active bevel gear 406 is driven to rotate through the convex strip on the transmission shaft 403, so that the mode switching can be achieved without stopping the machine.

[0042] like Figure 9As shown, the speed change assembly 5 includes a mounting base 501, a planetary carrier 502, a driving gear 503, a limit pin 504, a drive sleeve 505 and a gear plate 506. The mounting base 501 is fixedly mounted on the back of the metal recovery cabin 1 and a ring gear 507 is mounted inside to rotate coaxially. A motor with a reversing function is fixedly mounted on the back of the metal recovery cabin 1 and a driving gear 503 is fixedly mounted on the output shaft of the motor. The driving gear 503 and the ring gear 507 are arranged coaxially. The planetary carrier 502 is fixedly mounted on one end of the transmission shaft 403. A planetary gear 508 is rotatably mounted on the planetary carrier 502 and is meshed with the ring gear 507 and the driving gear 503. In the gear crusher configuration, the motor drives the driving gear 503 to rotate, and the driving gear 503 drives the planetary carrier 502 to rotate through the meshing action with the planetary gear 508. The ring gear 507 is limited by the limit pin 504, and the ring gear 507 does not rotate. Therefore, the transmission ratio of the planetary carrier 502 is relatively large, the speed of the planetary carrier 502 is relatively low, and a greater torque is obtained, which is suitable for the high torque requirements of the gear crusher.

[0043] like Figure 10As shown, an opening is provided at the bottom of the mounting seat 501, a limit latch 504 is slidably installed at the bottom of the mounting seat 501, a plurality of springs 509 are fixedly installed between the limit latch 504 and the mounting seat 501, a driving sleeve 505 is rotatably installed on the back of the metal recovery cabin 1, the limit latch 504 is movably inserted in the driving sleeve 505, two second protrusions 510 are integrally formed at the bottom of the limit latch 504, two spiral grooves are provided on the driving sleeve 505, the second protrusion 510 is slidably installed in the spiral groove on the driving sleeve 505, the tooth plate 506 is fixedly installed on the pitch adjustment slide 401, and the fixed sleeve on the driving sleeve 505 is provided with a meshing connection with the tooth plate 506 The driven gear 511, wherein, in the hammer crusher configuration, the adjustment seat 402 translates and drives the driving sleeve 505 to rotate through the meshing action of the tooth plate 506 and the driven gear 511. The driving sleeve 505 rotates and limits the second protrusion 510 through the spiral groove. The limiting latch 504 overcomes the elastic force of the spring 509 and slides downward, thereby unlocking the ring gear 507. At this time, the rotation of the driving gear 503 will also drive the planetary gear 508 and the ring gear 507 to rotate, which essentially changes the transmission ratio of the planetary gear 508 mechanism (the transmission ratio becomes smaller), thereby changing the output speed of the planetary carrier 502 (i.e., the transmission shaft 403), which is suitable for the high speed requirement of the hammer crusher. This design realizes the linkage between roller gap adjustment and roller speed adjustment. When the roller gap is increased (processing large or difficult-to-crush materials may require a larger roller gap and a lower speed), the linkage mechanism automatically selects a lower speed gear; when the roller gap is reduced (pursuing finer particle size or processing fragile materials may require a smaller roller gap and a higher speed), the linkage mechanism automatically selects a higher speed gear, and the rotation direction of the motor is different in the hammer crushing and tooth crushing states. In the tooth crushing state, the motor drives the two roller cores 2 to rotate toward the middle, tearing and crushing the metal scrap in the middle. In the hammer crushing state, the motor drives the two roller cores 2 to rotate outward. After the hard metal scrap falls into the middle of the metal recovery cabin 1, the high speed of the hammer head impacts the metal scrap to crush it, and then throws the metal scrap onto the scale plates on the two side walls of the metal recovery cabin 1 for secondary crushing.

[0044] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other form. Any person skilled in the art may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiments made in accordance with the technical essence of the present invention without departing from the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
