Description

Technical Field

[0001] The invention relates to the technical field of compressors, and in particular to a compressor for recycling and processing scrap metals. Background Art

[0002] In the current era of increasing awareness of resource recycling and environmental protection, the recycling of scrap metal has become an important issue. With the continuous expansion of industrial production and the improvement of consumption levels, the amount of scrap metal is also increasing year by year. In order to effectively manage and utilize these waste materials, the development of efficient scrap metal recycling equipment has become an urgent need of the industry. Compressors are key equipment in the process of scrap metal recycling. Their main function is to compress scrap metal into blocks for easy transportation and subsequent reprocessing. Existing compressor market products are mainly divided into two categories: fixed and mobile.

[0003] For fixed compressors, they are usually installed in a fixed location, such as a special processing plant. Such compressors need to rely on external transportation tools, such as trucks, to transport scrap metals scattered everywhere to the factory. After arriving at the destination, the scrap metals need to be unloaded next to the compressor and transported into the compression chamber by manual labor, forklifts or mechanical equipment such as grabs. This operation method not only increases the loading time and reduces work efficiency, but also increases the economic burden of the entire process due to the slow manual handling speed and the high cost of using forklifts and grabs. In addition, the frequent round trips between the compressor and the scrap metal pile by forklifts and grabs will also lead to a lack of continuity, thereby reducing production efficiency.

[0004] Although mobile compressors can solve the above problems to a certain extent, because they can be loaded onto semi-trailers and transported directly to the scrap metal storage site for on-site operations, this method still relies on forklifts or grabbers to complete the loading of scrap metals. The deployment and withdrawal of mobile compressors also takes time and resources, especially in places with inconvenient transportation or poor road conditions. This will undoubtedly increase the complexity and cost of operations. Moreover, even on-site, the need to constantly adjust the position of the compressor to approach the scrap metal pile will also bring additional time loss and labor intensity. Summary of the invention

[0005] In view of this, the present invention provides a compressor for recycling and processing scrap metals, which can overcome the shortcomings of existing compressors that, when in use, they usually rely on mechanical equipment such as forklifts or grabbers to load and unload scrap metals, which not only increases the complexity and cost of operation, but also makes it difficult to achieve continuous compression of scrap metals, resulting in low working efficiency.

[0006] The technical solution of the present invention is: a compressor for recycling and processing scrap metal, comprising a bucket arm, a mounting frame, a rotating rod, an arc-shaped grab plate, a first hydraulic cylinder, a rotating frame, a second hydraulic cylinder, a pressure plate, a rotating assembly and a cutting assembly, the bucket arm is installed on the boom of the excavator, the mounting frame is symmetrically connected to the bucket arm, the rotating rod is symmetrically and rotationally connected to the mounting frame, and first slide grooves are opened at both ends of the rotating rod, the arc-shaped grab plate is connected to the rotating rod, and second slide grooves are symmetrically opened on the arc-shaped grab plate, the first hydraulic cylinder is symmetrically and rotationally installed on the bucket arm, and the telescopic rod of the first hydraulic cylinder is rotationally connected to the arc-shaped grab plate, the rotating frame is rotationally connected to the mounting frame, the second hydraulic cylinder is installed on the top of the rotating frame, the pressure plate is connected to the telescopic rod of the second hydraulic cylinder, the rotating assembly is used to drive the rotating frame to rotate, and the cutting assembly is used to cut the scrap metal grabbed by the arc-shaped grab plate.

[0007] Furthermore, the rotating assembly includes a dual-axis motor and a connecting rod, the dual-axis motor is installed on a mounting frame, the connecting rod is rotatably connected in the mounting frame, and both ends of the connecting rod are respectively connected to the rotating frame and the output shaft of the dual-axis motor.

[0008] Furthermore, the cutting assembly includes a connecting plate, a rotating shaft, a first slider, a cutter and a second slider, the connecting plate is connected to the bottom of the rotating frame, the rotating shaft is symmetrically rotated and connected to the connecting plate, the first slider is connected to the end of the rotating shaft, and the first slider slides in the first slide groove, the cutter is connected to the bottom of the first slider, the second slider is connected to the side of the cutter, and the second slider slides in the second slide groove.

[0009] Furthermore, it also includes a sliding card bead and a connecting spring. The connecting plate is symmetrically provided with grooves. The sliding card bead is symmetrically slidably connected to the rotating shaft, and the sliding card bead is stuck in the groove. The connecting spring connects the sliding card bead and the rotating shaft.

[0010] Furthermore, it also includes a fixed rod, a rotating frame and a rotating assembly. The arc-shaped gripping plate is evenly spaced with arc-shaped holes. The fixed rod is symmetrically connected to the side of the arc-shaped gripping plate. The rotating frame is rotatably connected to the fixed rod. The rotating assembly is used to drive the rotating frame to rotate.

[0011] Furthermore, the rotating assembly includes a driving motor, a worm and a worm wheel. The driving motor is symmetrically installed on the side of the arc-shaped grab plate, the worm is connected to the output shaft of the driving motor, and the worm wheel is symmetrically connected to the rotating shaft of the rotating frame, and the worm wheel is meshed with the worm.

[0012] Furthermore, it also includes a first alloy bar and a second alloy bar, the first alloy bar is evenly spaced and connected to the side of the arc-shaped gripping plate, and the second alloy bar is evenly spaced and connected to the side of the rotating frame.

[0013] Furthermore, the shape of the rotating frame matches the shape of the arc-shaped hole, so that the rotating frame can rotate into the arc-shaped hole to completely block the arc-shaped hole.

[0014] The beneficial effects are: 1. The arc-shaped grab plate of the present invention can directly grab scrap metal from the scrap pile, and then the cutter can automatically cut off the excess part when the arc-shaped grab plate is closed, ensuring the regularity of the metal block. Then, the pressing plate can enter the interior of the arc-shaped grab plate to efficiently compress the metal to form a compact cylindrical shape, so that the grabbing, cutting and compression functions can be integrated into one. The whole process does not require additional loading equipment, thereby significantly reducing the time for loading and unloading, and improving the continuity and overall efficiency of the operation.

[0015] 2. The present invention can drive the rotating frame and the connecting plate to rotate with the axis of the connecting rod as the rotation center through the cooperation of the dual-axis motor and the connecting rod, so that the upper and lower positions of the pressure plate and the cutter can be freely exchanged, and then the compression and cutting functions can be freely exchanged. The structure is compact, and when the cutter is located above the pressure plate, the cutter can also be limited by the cooperation of the sliding card bead and the groove to prevent the cutter from rotating due to gravity, ensuring that the subsequent first slider and the second slider can slide back into the first slide groove and the second slide groove.

[0016] 3. The present invention designs the compressor to be mobile and has the ability to complete all processing steps by itself, which can greatly reduce the dependence on external transportation tools and auxiliary mechanical equipment. This not only saves the cost of purchasing and maintaining these equipment, but also reduces the demand for manual operation, thereby reducing labor intensity and labor costs. In addition, reducing the conversion time between equipment also indirectly reduces energy consumption, further saving operating costs. BRIEF DESCRIPTION OF THE DRAWINGS

The two ends of the connecting spring 18 are respectively connected to the sliding bead 17 and the rotating shaft 12.

[0031] like Figure 8 and Fig. 9 As shown, it also includes a fixed rod 20, a rotating frame 21 and a rotating assembly. A plurality of arc holes 19 are evenly spaced from left to right on the two arc-shaped grab plates 4. Two fixed rods 20 are symmetrically connected to the sides of the two arc-shaped grab plates 4 away from each other, and a rotating frame 21 is rotatably connected between the two fixed rods 20. The shape of the rotating frame 21 matches the shape of the arc hole 19 so that the rotating frame 21 can rotate into the arc hole 19 to completely block the arc hole 19. The rotating assembly is used to drive the rotating frame 21 to rotate; the rotating assembly includes a driving motor 22, a worm 23 and a worm wheel 24. The sides of the two arc-shaped grab plates 4 away from each other are symmetrically arranged on the left and right. A driving motor 22 is installed, and a worm 23 is connected to the output shaft of each driving motor 22. Worm wheels 24 are symmetrically connected to the rotating shafts 12 of the two rotating frames 21, and the worm wheels 24 are meshed with the worm 23, so that the driving motor 22 can drive the rotating frame 21 to rotate through the meshing of the worm 23 and the worm wheel 24; it also includes a first alloy bar 25 and a second alloy bar 26, and a plurality of first alloy bars 25 are evenly connected to the side of the two arc-shaped grab plates 4 away from each other, and the first alloy bars 25 are respectively located on the left and right sides of each arc-shaped hole 19, and a plurality of second alloy bars 26 are evenly connected to the side of the two rotating frames 21 away from each other.

[0032] In the initial state, the cutter 14 is located below the pressure plate 8, that is, the cutters 14 on the left and right sides are respectively located on the left and right sides of the arc-shaped grab plate 4; when it is necessary to compress the scrap metal, first control the excavator 1 to move to the side of the scrap metal pile, and then control the telescopic rod of the first hydraulic cylinder 5 to shorten, the first hydraulic cylinder 5 can drive the arc-shaped grab plates 4 on the front and rear sides to rotate and open to the side away from each other, the arc-shaped grab plates 4 can drive the rotating rod 3 to rotate, and the rotating rod 3 can squeeze the first sliders 13 on the front and rear sides to rotate to the side away from each other through the first slide groove 301. At the same time, the arc-shaped grab plate 4 can also squeeze the second sliders 15 on the front and rear sides to rotate to the side away from each other through the second slide groove 401, and the first slider 13 and the second slider 15 can cooperate to drive the cutters 1 on the front and rear sides. 4 is rotated to the side away from each other to open. Since the first slider 13 and the second slider 15 rotate with the axis of the rotating rod 3 as the rotation center at this time, the first slider 13 will not be separated from the first slide groove 301, and the second slider 15 will not be separated from the second slide groove 401. The first slider 13 will also drive the rotating shaft 12 to rotate, and the rotating shaft 12 will drive the sliding card bead 17 to rotate. At this time, the sliding card bead 17 will be squeezed by the inner wall of the connecting plate 11 and will retract and separate from the groove 16. The connecting spring 18 is compressed, and then the boom of the excavator 1 drives the bucket rod 101 to move, so as to drive the two arc-shaped grab plates 4 to extend into the scrap metal pile, and then the telescopic rod of the first hydraulic cylinder 5 is controlled to extend, and the first hydraulic cylinder 5 can drive the arc-shaped grab plates 4 on the front and rear sides to rotate to the side close to each other. The two arc-shaped grab plates 4 can cooperate to grab a sufficient amount of scrap metal. At the same time, the arc-shaped grab plates 4 can drive the cutters 14 on the front and rear sides to rotate and close to each other. The cutter 14 can cut off the scrap metal protruding on the left and right sides between the two arc-shaped grab plates 4. At this time, the cutter 14 can drive the rotating shaft 12 to reverse, and the rotating shaft 12 will drive the sliding card bead 17 to reverse and realign with the groove 16. The connecting spring 18 will return to its original state, driving the sliding card bead 17 to pop out and re-clamp the groove 16, and then the boom of the excavator 1 drives the bucket 101 to move, so as to drive the two arc-shaped grab plates 4 away from the metal pile and move to an open area on the ground. In this process, the worm 23 can be driven to rotate by the driving motor 22, and the worm 23 can drive the worm wheel 24 to rotate, and the worm wheel 24 can The rotating frames 21 on the front and rear sides are driven to rotate downward. At this time, the first alloy strip 25 and the second alloy strip 26 cooperate to cut off the scrap metal protruding from the arc hole 19 between the two arc grab plates 4. Finally, the rotating frame 21 will completely block the arc hole 19, so that the two arc grab plates 4 can form a complete cylinder to prevent the scrap metal between the two arc grab plates 4 from protruding from the arc hole 19 when compressed. At the same time, the dual-axis motor 9 can be controlled to drive the connecting rod 10 to rotate 180 degrees. The connecting rod 10 can drive the rotating frame 6, the second hydraulic cylinder 7, the pressure plate 8 and the connecting plate 11 to rotate 180 degrees. The connecting plate 11 can drive the rotating shaft 12, the first slider 13, the cutter 14 and the second slider 15 to rotate 180 degrees with the axis of the connecting rod 10 as the rotation center.So that the first slide block 13 can be separated from the first slide groove 301, and the second slide block 15 can be separated from the second slide groove 401. At this time, the cutter 14 is located above the pressure plate 8, that is, the pressure plates 8 on the left and right sides are respectively located on the left and right sides of the arc-shaped grab plate 4. At the same time, under the action of the sliding card beads 17, the cutter 14 can be limited to prevent the cutter 14 from rotating downward due to gravity. Then, the pressure plates 8 on the left and right sides are driven by the second hydraulic cylinder 7 to move to the side close to each other, so that the pressure plate 8 can enter between the two arc-shaped grab plates 4 and compress the scrap metal grabbed by the two arc-shaped grab plates 4. Under the coordinated action of the arc-shaped grab plates 4, the pressure plates 8 and the rotating frame 21, the scrap metal grabbed by the two arc-shaped grab plates 4 can be compressed into a regular cylindrical shape. Then, the dual-axis motor 9 can be controlled to drive the connecting rod 10 to rotate 180 degrees to reset. The connecting rod 10 can drive the rotating frame 6 and the second hydraulic cylinder 7. The pressing plate 8 and the connecting plate 11 rotate 180 degrees to reset. The connecting plate 11 can drive the rotating shaft 12, the first slider 13, the cutter 14 and the second slider 15 to rotate 180 degrees to reset with the axis of the connecting rod 10 as the rotation center, so that the first slider 13 can slide into the first slide groove 301 again, and the second slider 15 can slide into the second slide groove 401 again. Then the driving motor 22 is controlled to drive the worm 23 to reverse, and the worm 23 can drive the worm wheel 24 to reverse. The worm wheel 24 can drive the rotating frames 21 on the front and rear sides to rotate upward and separate from the arc hole 19. Then the two arc-shaped grab plates 4 are controlled to rotate and open, and the compressed scrap metal can be placed in an open area on the ground. Repeat the above operation to grab the scrap metal again, and the scrap metal can be automatically compressed during the grabbing and transfer process of the scrap metal, reducing the time for loading and unloading the scrap metal and improving the processing efficiency.
