Description

Technical Field

[0001] This application relates to the technical field of shearing equipment, and in particular to a rapid multi-blade shearing machine for dismantling end-of-life vehicles. Background Technology

[0002] After being scrapped, cars need to be processed before they can be reused as production materials for industrial production. The processing begins with dismantling the cars and using a shearing machine to cut the car bodies into smaller blocks or segments.

[0003] The most common shearing equipment used for cutting scrapped cars is the gantry shear. Conventional gantry shears use a "one-cut" shearing method. During the shearing process, the top of the gantry shear's blade holder moves downwards under the action of the pressure cylinder. The cutter is located at the bottom of the blade holder. When the cutter contacts the scrap metal, the thrust of the shearing cylinder is converted into shearing force to cut the metal as a whole. The resulting shredded material often does not meet recycling standards. Therefore, manual screening of the substandard material is required. Operators then perform secondary or multiple shearing operations on the material that does not meet recycling requirements, cutting it into smaller pieces of scrap metal until it meets recycling standards.

[0004] In related technologies, scrapped cars are cut into small pieces using a gantry shear. However, this requires manual labor to feed the material after one cut into the shear multiple times, which negatively impacts work efficiency. Utility Model Content

[0005] To reduce the adverse impact on work efficiency, this application provides a rapid multi-blade shearing machine for dismantling scrapped automobiles.

[0006] This application provides a rapid multi-blade shearing machine for dismantling end-of-life vehicles, employing the following technical solution:

[0007] A rapid multi-blade shearing machine for dismantling scrapped cars includes a housing with an open top. An extrusion assembly is located inside the housing. A first shearing blade is located below the extrusion assembly within the housing. A second shearing blade, cooperating with the first shearing blade, is located on the side of the housing away from the first shearing blade. A first hydraulic cylinder is installed on the side of the first shearing blade away from the second shearing blade. A discharge port is opened on one side of the lower end of the housing. A steering component is provided within the housing to drive the sheared car body segments to steer. A segmenting assembly for dividing the car body into sections is located at the discharge port.

[0008] By adopting the above technical solution, the scrapped car is inserted into the shell through the opening at the top of the shell. At this time, the scrapped car is positioned along the height direction of the shell. The extrusion assembly reciprocates and extrudes the scrapped car. When the extrusion assembly contracts, the extruded car moves downward under its own gravity until its end contacts the bottom wall inside the shell. At this time, the extrusion assembly continues to extrude the scrapped car, and the first hydraulic cylinder drives the first shearing blade to reciprocate, thereby cooperating with the second shearing blade to cut off the lower end of the scrapped car. Simultaneously with the movement of the first shearing blade, the steering component drives the cut-off part... The segmented car body rotates to be parallel to the bottom surface of the shell and moves through the discharge port to the segmenting assembly, which facilitates the segmenting assembly to further cut the segmented car body into blocks. The scrapped car is continuously squeezed by the extrusion assembly and moves downward under its own gravity to the first shearing blade for cutting when the extrusion assembly contracts. Then, it is turned by the steering component and moved to the segmenting assembly for cutting. This reduces the possibility of manually driving the segmented car body to move. Moreover, the extrusion assembly, the first and second shearing blades, the steering component and the segmenting assembly operate simultaneously, improving the cutting efficiency of scrapped cars and reducing the adverse effects on work efficiency.

[0009] Optionally, the first shearing blade is arranged along the width direction of the housing, and the first shearing blade is inclined from both ends to the middle along its own length direction away from the second shearing blade, and both sides of the first shearing blade arranged along the height direction of the housing are inserted into the housing and slidably connected to the housing.

[0010] By adopting the above technical solution, the shape of the first shear blade makes it easy for the first shear blade to cooperate with the second shear blade to shear the excavated car. Both sides of the first shear blade are inserted into the housing, thereby reducing the possibility of debris from the excavated car adhering to the side wall of the first shear blade when lubricating the sides of the first shear blade, reducing the adverse effect on the sliding of the first shear blade, and thus reducing the adverse effect on work efficiency.

[0011] Optionally, the steering component includes a steering plate fixedly connected to the lower side of the first shearing blade, the upper side of the steering plate being configured as an inclined surface that slopes toward the side closer to the extrusion assembly and away from the second shearing blade.

[0012] By adopting the above technical solution, the steering plate moves with the first shearing blade. When the first and second shearing blades work together to cut the scrapped car into segments, the cut scrapped car tilts towards the steering plate until it contacts the inclined surface on the steering plate. The first shearing blade drives the steering plate to continue moving towards the segmenting assembly until the cut scrapped car moves to the segmenting assembly, which facilitates further segmentation. The first shearing blade also drives the steering plate to reset, which facilitates the re-segmentation and steering of the scrapped car, improving the cutting efficiency of the scrapped car and reducing the adverse effects on work efficiency.

[0013] Optionally, a feed hopper communicating with the interior of the housing is installed on the upper side of the housing, and the extrusion assembly includes an extrusion box located in the housing and arranged along the width direction of the housing. The extrusion box slides along the length direction of the housing, and a second hydraulic cylinder is installed on the housing to drive the extrusion box to move.

[0014] By adopting the above technical solution, the scrapped car to be sheared is placed into the feeding hopper. The scrapped car on the side of the feeding hopper away from the second hydraulic cylinder moves downward under its own weight. At this time, the second hydraulic cylinder drives the extrusion box to move back and forth and extrudes the scrapped car, without affecting the feeding of the material in the feeding hopper, thus further improving work efficiency.

[0015] Optionally, the extrusion box includes a box body, the upper side of the box body is horizontal and the side of the box body near the second shear blade is vertical, and a plurality of sequentially arranged connecting plates are provided between the upper side of the box body and the side near the second shear blade. Each connecting plate includes a vertical first connecting part away from the second shear blade and a second connecting part near the second shear blade. The second connecting part is inclined downward towards the side near the second shear blade, and adjacent first connecting parts and second connecting parts are fixed to each other.

[0016] By adopting the above technical solution, the compression box consists of a box body and multiple sets of connecting plates. The connecting plates and the side of the box body near the second shearing blade form a stepped shape that gradually moves towards the second shearing blade. When the compression box compresses the scrapped car, the multiple sets of connecting plates and the side of the box body near the second shearing blade compress the scrapped car. At this time, the degree of compression of the scrapped car gradually increases along its own length. Since the second hydraulic cylinder drives the compression box to move back and forth, when the compression box moves away from the second shearing blade, the scrapped car moves downward, so that the degree of compression of the scrapped car is the same when it moves to be cut by the first shearing blade, thus improving work efficiency.

[0017] Optionally, the distance between the first shearing blade and the lower side wall inside the housing is equal to the side height of the housing body near the second shearing blade.

[0018] By adopting the above technical solution, after the lower end of the scrapped car is squeezed by the compression box, it moves under its own gravity to abut against the inner wall of the shell. At this time, the distance that the scrapped car is squeezed by the vertical side of the box body near the second shearing blade is equal to the height of the first shearing blade. This facilitates the cooperation between the first and second shearing blades to cut off the lower end of the scrapped car. At the same time, the end of the scrapped car body adjacent to the cut-off car body is squeezed by the vertical side of the box body near the second shearing blade to adapt to the height of the first shearing blade. Thus, the various sections of the scrapped car are gradually squeezed to adapt to the height of the first shearing blade through the stepped side of the box body, which facilitates cutting and improves work efficiency.

[0019] Optionally, the segmentation assembly includes a fixed frame fixedly connected to the lower end of the housing near the discharge port. The upper side of the fixed frame is provided with a plurality of first segmentation blades arranged along the length direction of the fixed frame and parallel to the length direction of the housing. Each of the first segmentation blades is provided with a second segmentation blade that cooperates with each other. The second segmentation blades are all rotatably connected to the fixed frame. The housing is provided with a rotating assembly for driving the second segmentation blades to rotate.

[0020] By adopting the above technical solution, the sheared sections of the vehicle body are moved sequentially by the steering plate to the upper side of the first segmenting blade and simultaneously contact multiple first segmenting blades. At this time, the rotating assembly drives the second segmenting blade to rotate towards the first segmenting blade, which facilitates cooperation with the corresponding first segmenting blade and simultaneously shears the vehicle body into blocks, which then fall through the fixing frame. This further facilitates the rapid shearing of scrapped vehicles and improves work efficiency.

[0021] Optionally, the rotating assembly includes a rotating shaft that passes through and is fixedly connected to the same end of the second segmenting blade away from the housing and is rotatably connected to the fixing frame. A drive rod is fixedly connected to the end of the second segmenting blade away from the rotating shaft. A third hydraulic cylinder is hinged to the side of the housing near the rotating shaft, and the third hydraulic cylinder is hinged to the drive rod.

[0022] By adopting the above technical solution, the telescopic rod of the third hydraulic cylinder can be extended or shortened, thereby facilitating the rotation of the second slitting cutter and the rotating shaft through the drive rod to cut the car body, thus improving work efficiency.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] The scrapped car is continuously squeezed by the compression component and moves downward under its own gravity as the compression component contracts to be cut by the first shearing blade. Then it is turned by the steering component and moved to the segmentation component to be segmented. This reduces the possibility of manually driving the segmented car body to move. Moreover, the compression component, the first shearing blade, the second shearing blade, the steering component, and the segmentation component operate simultaneously, which improves the cutting efficiency of scrapped cars and reduces the adverse effects on work efficiency.

[0025] When the first and second shearing blades work together to cut the scrapped car into sections, the cut scrapped car tilts towards the steering plate until it contacts the inclined surface on the steering plate. The first shearing blade drives the steering plate to continue moving towards the segmentation assembly until the cut scrapped car moves to the segmentation assembly, which facilitates further segmentation. The first shearing blade also drives the steering plate to reset, which facilitates the re-segmentation and steering of the scrapped car, improving the cutting efficiency of the scrapped car and reducing the adverse effects on work efficiency.

[0026] The connecting plate and the box body form a stepped shape that gradually moves closer to the second shear blade. When the compression box compresses the scrapped car, multiple sets of connecting plates and the box body on the side near the second shear blade compress the scrapped car. At this time, the degree of compression of the scrapped car gradually increases along its own length. As the second hydraulic cylinder drives the compression box to move back and forth, when the compression box moves away from the second shear blade, the scrapped car moves downward, so that the degree of compression of the scrapped car is the same when it moves to be cut by the first shear blade, thus improving work efficiency.

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] This application discloses a rapid multi-blade shearing machine for dismantling scrapped automobiles. (Refer to...) Figure 1 and Figure 2 A rapid multi-blade shearing machine for dismantling scrapped cars includes a vertical housing 1 with an opening at the top. A feed hopper 11, which communicates with the interior of the housing 1 and is used to hold scrapped cars to be sheared, is installed at the top of the housing 1. An outlet 12, which communicates with the interior of the housing 1, is opened on one side of the lower end of the housing 1.

[0034] Reference Figure 2 and Figure 3The upper side of the housing 1 is provided with a compression assembly 2 for compressing scrapped vehicles. The lower side of the compression assembly 2 is provided with a first shearing blade 3 located on the side of the housing 1 away from the discharge port 12. The first shearing blade 3 is horizontal and arranged along the width direction of the housing 1. Along its length, the first shearing blade 3 is configured in a "V" shape, gradually tilting away from the discharge port 12 from both ends. In this embodiment, the included angle between the two ends of the first shearing blade 3 is 160°. A second shearing blade 32, arranged along the width direction of the housing 1 and adapted to the first shearing blade 3, is fixedly connected to the side of the housing 1 near the discharge port 12. The height of the second shearing blade 32 is higher than the upper height of the discharge port 12.

[0035] Reference Figure 2 , Figure 3 and Figure 4 A horizontal sliding frame 31 is fixedly connected to the side of the first shearing blade 3 away from the discharge port 12. Both vertical sides of the sliding frame 31 are inserted into the inner wall of the housing 1 and are slidably connected to the housing 1 along the length of the housing 1. A horizontal first hydraulic cylinder 33 is fixedly connected to the side of the housing 1 away from the discharge port 12. The telescopic rod of the first hydraulic cylinder 33 passes through the side wall of the housing 1 and is fixedly connected to the sliding frame 31.

[0036] The sliding frame 31 is equipped with a steering component that drives the segmented car body to turn. The steering component includes a steering plate 34 fixedly connected to the lower side of the first shearing blade 3 and arranged along the width direction of the housing 1. The side of the steering plate 34 near the second shearing blade 32 is configured as an upward inclined surface that is inclined away from the discharge port 12. The lower end of the outer side of the housing 1 is provided with a segmenting assembly 4 for further shearing the segmented car body.

[0037] The scrapped car to be sheared is placed into the feed hopper 11. The scrapped car on the side away from the second hydraulic cylinder 23 in the feed hopper 11 moves downward under its own weight and enters the housing 1. At this time, the scrapped car is set along the height direction of the housing 1. The extrusion assembly 2 reciprocates and extrudes the scrapped car. When the extrusion assembly 2 contracts, the extruded car moves downward under its own weight until its end contacts the bottom wall inside the housing 1. At this time, the extrusion assembly 2 continues to extrude the scrapped car, and the first hydraulic cylinder 33 drives the first shearing blade 3 to reciprocate, thereby cooperating with the second shearing blade 32 to cut off the lower end of the scrapped car.

[0038] The steering plate 34 moves with the first shearing blade 3. When the first shearing blade 3 and the second shearing blade 32 cooperate to cut the scrapped car into segments, the cut scrapped car tilts towards the steering plate 34 until it contacts the inclined surface on the steering plate 34. The first shearing blade 3 drives the steering plate 34 to continue moving towards the segmenting assembly 4 until the cut scrapped car moves to the segmenting assembly 4, so that the segmenting assembly 4 can further cut the segmented car body into blocks. The first shearing blade 3 drives the steering plate to reset, so that the scrapped car can be segmented and steered again, improving the cutting efficiency of the scrapped car.

[0039] The scrapped car is continuously squeezed by the squeezing component 2 and moves downward under its own gravity to the first shearing blade 3 for shearing when the squeezing component 2 contracts. Then it is turned by the steering component and moves to the segmenting component 4 for segmentation. The squeezing component 2, the first shearing blade 3 and the second shearing blade 32, the steering component and the segmenting component 4 operate simultaneously to improve the shearing efficiency of the scrapped car.

[0040] The shape of the first shearing blade 3 makes it easy for the first shearing blade 3 to cooperate with the second shearing blade 32 to shear the crushed scrapped car. Both sides of the first shearing blade 3 are inserted into the housing 1, thereby reducing the possibility of scrapped car debris adhering to the side wall of the first shearing blade 3 when lubricating both sides of the first shearing blade 3.

[0041] Reference Figure 2 and Figure 3 The extrusion assembly 2 includes a horizontal extrusion box 21, which includes a box body 211 arranged along the width direction of the housing 1. The upper side of the box body 211 is horizontal, and the side of the box body 211 near the discharge port 12 is vertical. The height of the side of the box body 211 near the discharge port 12 is equal to the distance between the first shearing blade 3 and the inner wall of the housing 1. The line connecting the horizontal upper side of the box body 211 and the vertical side near the discharge port 12 slopes downward towards the side near the discharge port 12. A plurality of sequentially arranged connecting plates 212 are provided between the horizontal upper side of the box body 211 and the vertical side near the discharge port 12. In this embodiment, three connecting plates are provided.

[0042] The connecting plate 212 includes a vertical first connecting portion 2121 on the side away from the discharge port 12 and a second connecting portion 2122 near the discharge port 12. The second connecting portions 2122 are all inclined downward towards the side near the discharge port 12. In this embodiment, the angle between the second connecting portion 2122 and the horizontal plane is 45°, and the lower side of the second connecting portion 2122 is located on the upper side of the first connecting portion 2121 of the adjacent connecting plate 212 and is fixedly connected to the upper side of the adjacent first connecting portion 2121.

[0043] Both vertical sides of the extrusion box 21 are fixedly connected to horizontal guide rods 22 arranged along the length of the housing 1. The guide rods 22 are inserted into the inner wall of the housing 1 and are slidably connected to the inner wall of the housing 1. A horizontal second hydraulic cylinder 23 is fixedly connected to the upper end of the housing 1 on the side away from the discharge port 12. The telescopic rod of the second hydraulic cylinder 23 passes through the housing 1 and is fixedly connected to the extrusion box 21.

[0044] The scrapped car to be sheared is placed into the feeding hopper 11. The scrapped car on the side of the feeding hopper 11 away from the second hydraulic cylinder 23 moves downward under its own weight. At this time, the second hydraulic cylinder 23 drives the extrusion box 21 to move back and forth and extrude the scrapped car, without affecting the feeding in the feeding hopper 11.

[0045] The compression box 21 consists of a box body 211 and multiple sets of connecting plates 212. The connecting plates 212 and the box body 211 near the second shear blade 32 form a stepped shape that gradually moves towards the second shear blade 32. When the compression box 21 compresses the scrapped car, the multiple sets of connecting plates 212 and the box body 211 near the second shear blade 32 compress the scrapped car. At this time, the degree of compression of the scrapped car gradually increases along its own length.

[0046] As the second hydraulic cylinder 23 drives the extrusion box 21 to reciprocate, when the extrusion box 21 moves away from the second shearing blade 32, the scrapped car moves downward, so that each section of the scrapped car moves to the same degree of extrusion when it is sheared by the first shearing blade 3.

[0047] After the lower end of the scrapped car is squeezed by the compression box 21, it moves under its own weight to abut against the inner wall of the shell 1. At this time, the distance that the scrapped car is squeezed by the vertical side of the box body 211 near the second shearing blade 32 is equal to the height of the first shearing blade 3, which makes it easy for the first shearing blade 3 and the second shearing blade 32 to cooperate with each other and cut off the lower end of the scrapped car. At this time, the end of the scrapped car adjacent to the cut-off car body is squeezed by the vertical side of the box body 211 near the second shearing blade 32 to adapt to the height of the first shearing blade 3. Thus, each section of the scrapped car is gradually squeezed to adapt to the height of the first shearing blade 3 through the stepped side of the box body 211, which facilitates cutting.

[0048] Reference Figure 1 , Figure 3 and Figure 4 The segmentation component 4 includes a fixing frame 41 fixedly connected to the lower end of the outer side of the housing 1 near the discharge port 12. The fixing frame 41 is integrally formed with the housing 1. The fixing frame 41 is horizontal and arranged along the length direction of the housing 1. A plurality of first segmenting blades 42 are fixedly connected to the upper side of the fixing frame 41 and are evenly distributed along the width direction of the fixing frame 41. In this embodiment, two first segmenting blades 42 are provided and the first segmenting blades 42 are vertical and arranged along the length direction of the fixing frame 41.

[0049] Each side of the first dividing blade 42 is provided with a vertical second dividing blade 43 corresponding to the first dividing blade 42. The end of the second dividing blade 43 away from the housing 1 is rotatably connected to the upper side of the fixing frame 41. The housing 1 is provided with a rotating assembly 5 that drives the second dividing blade 43 to rotate simultaneously.

[0050] Reference Figure 1 and Figure 3 The rotating assembly 5 includes a rotating shaft 51 that passes through the end of the second dividing blade 43 away from the housing 1 and is fixedly connected to the second dividing blade 43. The rotating shaft 51 is horizontal and rotatably connected to the upper side of the fixing frame 41. The same drive rod 52 is fixedly connected to the upper side of the second dividing blade 43 near the end of the housing 1. A third hydraulic cylinder 53 is hinged to the side of the housing 1 near the fixing frame 41, facing the drive rod 52. The extension rod of the third hydraulic cylinder 53 is hinged to the drive rod 52.

[0051] The sheared sections of the vehicle body are moved sequentially by the steering plate 34 to the upper side of the first dividing blade 42 and simultaneously contact multiple first dividing blades 42. At this time, the third hydraulic cylinder 53 drives the second dividing blade 43 to rotate towards the first dividing blade 42 through the drive rod 52 and the rotating shaft 51, so as to cooperate with the corresponding first dividing blade 42 and simultaneously shear the vehicle body into blocks. At this time, the block-shaped vehicle body passes through the fixing frame 41 and falls down, completing the shearing of the scrapped car.

[0052] The first hydraulic cylinder 33 and the second hydraulic cylinder 23 are both fitted with and fixedly connected to mounting boxes 6. When installing the first hydraulic cylinder 33 and the second hydraulic cylinder 23, the mounting boxes 6 are inserted into the housing 1. The housing 1 is provided with mounting pins 61 that correspond one-to-one with the two sides of the mounting boxes 6 and are parallel to the width direction of the housing 1. The mounting pins 61 pass through the side wall of the housing 1 and are inserted into the mounting boxes 6.

[0053] The first hydraulic cylinder 33, the second hydraulic cylinder 23, and the third hydraulic cylinder 53 are all connected to a high-pressure hydraulic pump (not shown in the figure) and a low-pressure hydraulic pump (not shown in the figure), and pressure sensors (not shown in the figure) are installed on the first hydraulic cylinder 33, the second hydraulic cylinder 23, and the third hydraulic cylinder 53. The pressure sensors are all wirelessly connected to the control host (not shown in the figure).

[0054] When the telescopic rods of the first hydraulic cylinder 33, the second hydraulic cylinder 23, and the third hydraulic cylinder 53 extend, the high-pressure hydraulic pump and the low-pressure hydraulic pump work simultaneously. At this time, the corresponding pressure sensor detects the pressure value. When the pressure value reaches the set maximum pressure value, the control host drives the low-pressure hydraulic pump to stop working, thereby driving the telescopic rods of the corresponding first hydraulic cylinder 33, the second hydraulic cylinder 23, and the third hydraulic cylinder 53 to extend rapidly through the high-pressure hydraulic pump. At this time, the pressure value detected by the pressure sensor continues to rise, which facilitates rapid shearing and extrusion and improves work efficiency.

[0055] When the telescopic rods of the first hydraulic cylinder 33, the second hydraulic cylinder 23, and the third hydraulic cylinder 53 retract until the pressure value detected by the pressure sensor decreases to the set maximum pressure value, the control host drives the low-pressure hydraulic pump to start working. This allows the high-pressure and low-pressure hydraulic pumps to simultaneously drive the corresponding telescopic rods of the first hydraulic cylinder 33, the second hydraulic cylinder 23, and the third hydraulic cylinder 53 to retract, thereby saving energy and achieving the effect of energy saving and acceleration.

[0056] The implementation principle of a rapid multi-blade shearing machine for dismantling scrapped cars according to an embodiment of this application is as follows: the scrapped car is continuously squeezed by the compression box 21 and moves downward under its own gravity when the compression box 21 contracts to the first shearing blade 3 for shearing. Then, it is turned by the steering plate 34 and moved to the fixed frame 41 for segmentation. The compression box 21, the first shearing blade 3 and the second shearing blade 32, the steering plate 34, the first segmenting blade 42 and the second segmenting blade 43 operate simultaneously until the scrapped car is completely sheared.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
