Description

Technical Field

[0001] This utility model relates to the field of waste recycling machinery technology, and in particular to a four-axis pressurized arm type scrap iron crusher. Background Technology

[0002] Scrap metal shredders are key equipment in the scrap recycling industry, used to break large pieces of scrap metal into smaller pieces for further processing. With the rapid development of the scrap recycling industry, higher requirements are placed on the processing capacity and reliability of shredders, and shredder technology is gradually developing towards multi-shaft, intelligent, and high-efficiency directions.

[0003] Currently, common crushers in existing technologies include single-shaft crushers, double-shaft crushers, and triple-shaft crushers. Although single-shaft, double-shaft, and triple-shaft crushers can crush scrap iron using crushing blades, the scrap iron tends to accumulate and get stuck inside the crushing box when it is fed into the crushing box during the crushing process, thus affecting the crushing efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide a four-shaft pressurized feed arm type scrap iron crusher to address the problem that scrap iron tends to accumulate and get stuck in the crushing box when it is put into the crushing process, thus affecting the crushing efficiency.

[0005] The device includes: a frame, with a crushing box mounted on the top of the frame and a discharge port at the bottom of the crushing box; a crushing mechanism, comprising four cutter shafts rotatably connected to the inner wall of the crushing box, the centers of the four cutter shafts being located on the same horizontal plane; four motors mounted on the top of the frame; one end of each cutter shaft extending through the crushing box; the discharge port at the bottom of the crushing box being fixedly connected to the output shaft of the motor; multiple evenly distributed blades fixedly connected to the surface of each cutter shaft; and a fixed frame fixedly connected to the top of the crushing box with the discharge port at the bottom; feed frames fixedly connected to both sides of the fixed frame, the feed frames communicating with the fixed frame; and pressure plates rotatably connected to both sides of the top of the fixed frame.

[0006] In one embodiment, the crushing mechanism further includes two fixed rods fixedly connected to the surface of the fixed frame. A hydraulic cylinder is hinged to one side of the top of each fixed rod, and a connecting rod is rotatably connected to one side of the pressure plate. The telescopic end of the hydraulic cylinder is fixedly connected to the surface of the corresponding connecting rod. This facilitates the periodic downward rotation of the pressure plate, ensuring the stability of the device operation.

[0007] In one embodiment, a plurality of evenly distributed springs are fixedly connected to the upper inner wall of the pressure plate. A movable plate is fixedly connected to the end of each spring away from the inner wall of the pressure plate. The end of the movable plate away from the spring extends through the pressure plate and is fixedly connected to a round rod. Under the action of the movable plate and the springs, the two pressure plates rotate downwards to compress the scrap iron, forming a unified pressure plate. This prevents scrap iron from entering between the two pressure plates during rotation, ensuring the stability of the two pressure plates during downward rotation.

[0008] In one embodiment, a protective plate is fixedly connected to the top of the feed frame, and the overall shape of the protective plate is "U". This helps to protect the operating area of ​​the hydraulic cylinder and avoids affecting the pressure plate during the scrap metal feeding process.

[0009] In one embodiment, multiple protrusions arranged in a rectangular array are fixedly connected to opposite sides of the two pressure plates. The overall shape of the protrusions is a flat-topped cone. This helps to increase the force exerted by the pressure plates on scrap iron and also protects the pressure plates.

[0010] In one embodiment, the multiple blades on the surface of the cutter shaft are arranged in a spiral, and the number of blades on the cutter shaft surface is twelve. This facilitates continuous crushing during the crushing process, improving the crushing effect on scrap iron.

[0011] In one embodiment, the blades on adjacent cutter shaft surfaces are staggered. This ensures effective crushing when the blades on adjacent cutter shaft surfaces interact.

[0012] Beneficial effects 1. By setting two feed frames in the above-mentioned crushing mechanism, the scrap iron can fall more evenly into the crushing box after entering the fixed frame, resulting in better crushing effect. During crushing, multiple blades on the four cutter shafts crush the scrap iron simultaneously, which helps to improve the crushing efficiency. Furthermore, by driving the pressure plate to rotate and press down periodically during the crushing process, the scrap iron in the fixed frame is squeezed to enter the crushing box more evenly, preventing the scrap iron from accumulating and getting stuck in the crushing box, thus ensuring the crushing efficiency of the scrap iron. 2. Under the action of the moving plate and the spring, it is beneficial for the two pressure plates to rotate downwards and squeeze the scrap iron to form an integral pressure plate, which prevents scrap iron from entering between the two pressure plates when the pressure plates rotate, thus ensuring the stability of the two pressure plates when rotating downwards.

[0021] The following is combined with Figures 1-5 This invention describes a four-axis pressurized feed arm type scrap metal crusher.

[0022] In one embodiment, a four-axis pressurized feeder type scrap metal shredder includes: a frame 100, a crushing box 200 mounted on the top of the frame 100, and a discharge port at the bottom of the crushing box 200; a crushing mechanism 300, which includes four cutter shafts 310 rotatably connected to the inner wall of the crushing box 200, the centers of the four cutter shafts 310 being located on the same horizontal plane, and four motors 320 mounted on the top of the frame 100, with one end of each cutter shaft 310 penetrating through the crusher. The bottom of the crushing box 200 has a discharge port and is fixedly connected to the output shaft of the motor 320. Multiple evenly distributed blades 330 are fixedly connected to the surface of the cutter shaft 310. The top of the bottom of the crushing box 200 has a discharge port and is fixedly connected to a fixed frame 340. Feed frames 350 are fixedly connected to both sides of the fixed frame 340. The feed frames 350 are connected to the fixed frame 340. Pressure plates 360 are rotatably connected to both sides of the top of the fixed frame 340.

[0023] It should be noted that the cutter shaft 310 is made of 40Cr alloy steel with surface hardening treatment. The part of the cutter shaft 310 that extends through the crushing box 200 is fixed to the frame 100 through the bearing seat. The four cutter shafts 310 correspond one-to-one with the four motors 320.

[0024] In this embodiment, the cutting teeth of the blade 330 mounted on the surface of one of the outermost cutter shafts 310 face opposite directions to the cutting teeth of the blades 330 mounted on the surfaces of the other three cutter shafts 310. When this device is used to crush scrap iron, the controller starts the four motors 320. One motor 320 drives one of the cutter shafts 310 to rotate counterclockwise, thereby driving the blades 330 mounted on the surface to rotate counterclockwise synchronously. The other three motors 320 drive their corresponding cutter shafts 310 to rotate clockwise, thereby driving the blades 330 mounted on the surface to rotate clockwise synchronously. At this time, the shearing forces generated by the blades 330 on the surfaces of two adjacent cutter shafts 310 are opposite, thus enabling the crushing operation of scrap iron. See reference. Figure 3 .

[0025] It should be noted that before starting the equipment, check the tightness of each component. When feeding material into the feed frame 350 during the crushing process of scrap iron, it is necessary to control the feeding speed. When starting the motor 320, it is necessary to confirm that the corresponding cutter shaft 310 is rotating in the correct direction. Also, the residual material in the fixed frame 340 and crushing box 200 needs to be cleaned regularly during the use of the device. like Figure 3 and Figure 4 As shown, the crushing mechanism 300 also includes two fixed rods 370 fixedly connected to the surface of the fixed frame 340. A hydraulic cylinder 371 is hinged to one side of the top of the fixed rod 370, and a connecting rod 372 is rotatably connected to one side of the pressing plate 360. The telescopic end of the hydraulic cylinder 371 is fixedly connected to the surface of the corresponding connecting rod 372.

[0026] It should be noted that the hydraulic cylinder 371 is an HSG series with a rated pressure of 16MPa. Before crushing scrap iron, the hydraulic system must be turned on and the operation of the pressing arm must be tested to ensure it is working properly.

[0027] In this embodiment, the two hydraulic cylinders 371 are symmetrically distributed, and when the pressure plate 360 ​​is in a vertical state, the hydraulic cylinders 371 are in an inclined state.

[0028] like Figure 5 As shown, multiple evenly distributed springs 362 are fixedly connected to the upper end of the inner wall of the pressure plate 360. A movable plate 361 is fixedly connected to the end of the spring 362 away from the inner wall of the pressure plate 360. The end of the movable plate 361 away from the spring 362 passes through the pressure plate 360 ​​and is fixedly connected to a round rod 363.

[0029] In this embodiment, the inner wall of the pressure plate 360 ​​is provided with a moving groove that matches the moving plate 361. The spring 362 is disposed in the moving groove. In the initial state, the round rod 363 moves away from the pressure plate 360 ​​under the action of the spring 362. It should be noted that when the two pressure plates 360 rotate 65 degrees, the surfaces of the two round rods 363 will come into contact, and the hydraulic cylinder 371 will push the pressure plate 360 ​​to rotate at an angle of less than 90 degrees.

[0030] like Figure 2 As shown, a protective plate 351 is fixedly connected to the top of the feed frame 350, and the overall shape of the protective plate 351 is "U".

[0031] In this embodiment, the rotation of the hydraulic cylinder 371 does not affect the protective plate 351, and the protective plate 351 protects the rotation area of ​​the hydraulic cylinder 371.

[0032] like Figure 4 As shown, multiple protrusions 364 arranged in a rectangular array are fixedly connected to the opposite sides of the two pressure plates 360. The overall shape of the protrusions 364 is a flat-topped cone. The protrusions 364 are made of cemented carbide.

[0033] like Figure 3 As shown, the multiple blades 330 on the surface of the cutter shaft 310 are arranged in a spiral, and the number of blades 330 on the surface of the cutter shaft 310 is twelve. The blades 330 on the surfaces of adjacent cutter shafts 310 are staggered. The blades 330 are made of cemented carbide components.

[0034] Working principle: When crushing scrap iron, the controller starts four motors 320, which drive the corresponding cutter shafts 310 to rotate. This causes adjacent cutter shafts 310 to rotate, generating opposing shearing forces on their surface blades 330. Simultaneously, the scrap iron enters the fixed frame 340 from the feed frames 350 on both sides and then from the fixed frame 340 into the crushing chamber 200. Multiple blades 330 on the surfaces of the four cutter shafts 310 simultaneously crush the scrap iron. During this process, the controller activates the hydraulic cylinder 371, which operates periodically. When 371 is running, the telescopic end of the hydraulic cylinder 371 will drive the corresponding pressure plate 360 ​​to rotate through the connecting rod 372. When the two pressure plates 360 rotate to a certain angle, the surfaces of the two round rods 363 will be in contact. At this time, the two pressure plates 360 continue to rotate, so that the two moving plates 361 squeeze each other and the spring 362 is compressed. At the same time, the two pressure plates 360 and the two moving plates 361 will form an integral pressure plate that rotates downward to squeeze the scrap iron in the fixed frame 340 into the crushing box 200 for crushing. The crushed scrap iron is discharged through the discharge port at the bottom of the crushing box 200.

[0035] It should be noted that the motor 320 and hydraulic cylinder 371 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the motor 320 and hydraulic cylinder 371 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
