Description

Technical Field

[0001] This application relates to the technical field of shearing equipment, and particularly to a fast multi-knife shearing machine for disassembling scrapped automobiles. Background Art

[0002] After a scrapped automobile is recycled, it needs to be processed and then reused as production materials for industrial production. During processing, first, the scrapped automobile needs to be disassembled, and a shearing machine is used to shear the body of the scrapped automobile, so as to shear the body into smaller blocks or segments.

[0003] A common shearing equipment for shearing scrapped automobiles is a gantry shearing machine. The conventional gantry shearing machine adopts a "one-cut" shearing form. During the shearing process, the top of the tool holder of the gantry shearing machine moves downward under the drive of the blank holding oil cylinder. The cutting tool is placed at the bottom of the tool holder. When the cutting tool contacts the waste metal, the thrust of the shearing oil cylinder is converted into a shearing force to achieve the overall cutting of the metal. Under such a cutting method, the broken materials generated often cannot meet the recycling standards. At this time, it is necessary for workers to screen the over-standard materials, and then the operators will cut the materials that do not meet the recycling requirements with a shearing machine for a second or multiple times to shear them into smaller blocks of waste metal until the recycling standards are met.

[0004] In the related art, when a gantry shearing machine is used to shear a scrapped automobile into small pieces, it is necessary for workers to put the materials after the first shearing into the shearing machine for multiple shearing, which has an adverse effect on the working efficiency. Summary of the Invention

[0005] In order to reduce the adverse effect on the working efficiency, this application provides a fast multi-knife shearing machine for disassembling scrapped automobiles.

[0006] The fast multi-knife shearing machine for disassembling scrapped automobiles provided by this application adopts the following technical solutions: A fast multi-knife shearing machine for disassembling scrapped automobiles includes a housing with an open upper end. An extrusion assembly is arranged inside the housing. A first shearing knife is arranged in the housing below the extrusion assembly. A second shearing knife that cooperates with the first shearing knife is arranged on one side of the housing interior far from the first shearing knife. A first hydraulic cylinder is installed on the side of the first shearing knife far from the second shearing knife. An outlet is opened on one side of the lower end of the housing. A turning member for driving each section of the sheared vehicle body to turn is arranged in the housing. A block dividing assembly for dividing the vehicle body into blocks is arranged at the outlet.

[0007] By adopting the above technical solution, the scrapped vehicle is put into the housing through the opening at the upper end of the housing. At this time, the scrapped vehicle is arranged along the height direction of the housing. The extrusion assembly reciprocates and extrudes the scrapped vehicle. When the extrusion assembly contracts, the extruded scrapped vehicle moves downward under the action of its own gravity until the end contacts the bottom wall inside the housing. At this time, the extrusion assembly continues to extrude the scrapped vehicle, and the first hydraulic cylinder drives the first shear blade to reciprocate, so as to cooperate with the second shear blade and cut off the lower end of the scrapped vehicle. At the same time as the first shear blade moves, the steering member drives the cut segmented vehicle body to rotate parallel to the bottom surface of the housing and move to the block splitting assembly through the discharge port, which facilitates the block splitting assembly to further cut the segmented vehicle body into blocks. The scrapped vehicle is continuously extruded by the extrusion assembly and moves downward to the first shear blade under the drive of its own gravity when the extrusion assembly contracts, and then is steered by the steering member and moves to the block splitting assembly for block splitting, reducing the possibility of manually driving the segmented vehicle body to move. Moreover, the extrusion assembly, the first shear blade and the second shear blade, the steering member and the block splitting assembly act simultaneously, improving the shearing efficiency of the scrapped vehicle and reducing the adverse impact on the working efficiency.

[0008] Optionally, the first shear blade is arranged along the width direction of the housing. The first shear blade gradually inclines away from the second shear blade from both ends to the middle along its own length direction, and both sides of the first shear blade arranged along the height direction of the housing are inserted into the housing and are slidably connected to the housing.

[0009] By adopting the above technical solution, the shape of the first shear blade enables the first shear blade to easily cooperate with the second shear blade and shear the extruded scrapped vehicle. Moreover, both sides of the first shear blade are inserted into the housing, thereby reducing the possibility that debris of the scrapped vehicle adheres to the side wall of the first shear blade when lubricating both sides of the first shear blade, reducing the adverse impact on the sliding of the first shear blade, and further reducing the adverse impact on the working efficiency.

[0010] Optionally, the steering member includes a steering plate fixedly connected to the lower side of the first shear blade. The upper side of the steering plate is provided with an inclined surface that inclines towards the side close to the extrusion assembly and away from the second shear blade.

[0011] By adopting the above technical solution, the steering plate moves with the first shear blade. When the first shear blade and the second shear blade cooperate to cut the scrapped vehicle, the cut scrapped vehicle inclines towards the side close to the steering plate until it contacts the inclined surface on the steering plate. The first shear blade drives the steering plate to continue moving towards the side close to the block splitting assembly until the cut scrapped vehicle moves to the block splitting assembly, which facilitates further block splitting. Moreover, the first shear blade drives the steering plate to reset, facilitating cutting and steering the scrapped vehicle again, improving the shearing efficiency of the scrapped vehicle and reducing the adverse impact on the working efficiency.

[0012] Optionally, a feed hopper communicating with the interior of the housing is installed on the upper side of the housing. 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 for driving the extrusion box to move is installed on the housing.

[0013] By adopting the above technical solution, the scrapped vehicle to be sheared is placed into the feed hopper. The scrapped vehicle on the side of the feed hopper away from the second hydraulic cylinder moves downward under its own gravity. At this time, the second hydraulic cylinder drives the extrusion box to reciprocate and extrude the scrapped vehicle, and at the same time, it does not affect the feeding in the feed hopper, further improving the working efficiency.

[0014] Optionally, the extrusion box includes a box body. The upper side of the box body is horizontal and the side of the box body close to the second shear blade is vertical. A plurality of groups of connecting plates connecting the two are arranged between the upper side surface of the box body and the side surface close to the second shear blade. The connecting plates each include a vertical first connecting portion away from the second shear blade and a second connecting portion on the side close to the second shear blade. The second connecting portion slopes downward toward the side close to the second shear blade, and the adjacent first connecting portion and the second connecting portion are fixed to each other.

[0015] By adopting the above technical solution, the extrusion box is composed of a box body and a plurality of groups of connecting plates, and the connecting plates and the side of the box body close to the second shear blade form a stepped shape gradually toward the direction close to the second shear blade. When the extrusion box extrudes the scrapped vehicle, the plurality of groups of connecting plates and the side of the box body close to the second shear blade extrude the scrapped vehicle. At this time, the degree of extrusion of the scrapped vehicle gradually increases along its own length direction. Since the second hydraulic cylinder drives the extrusion box to reciprocate, when the extrusion box moves in the direction away from the second shear blade, the scrapped vehicle moves downward, so that the degree of extrusion of the scrapped vehicle when it moves to be sheared by the first shear blade is the same, improving the working efficiency.

[0016] Optionally, the distance between the first shear blade and the lower side wall inside the housing is equal to the height of the side surface of the box body close to the second shear blade.

[0017] By adopting the above technical solution, after the lower end of the scrapped vehicle is extruded by the extrusion box, it moves under its own gravity to abut against the inner side wall of the housing. At this time, the distance that the scrapped vehicle is extruded by the vertical side surface of the box body close to the second shear blade is equal to the height of the first shear blade, which is convenient for the first shear blade and the second shear blade to cooperate with each other and cut off the lower end of the scrapped vehicle. And at this time, one end of the vehicle body of the scrapped vehicle adjacent to the cut-off vehicle body is extruded by the vertical side surface of the box body close to the second shear blade to be adapted to the height of the first shear blade. Thus, each section of the scrapped vehicle is gradually extruded to be adapted to the height of the first shear blade through the stepped side of the box body, which is convenient for shearing and improves the working efficiency.

[0018] Optionally, the block component includes a fixing frame fixedly connected to the lower end of the housing near the discharge port. A plurality of first block knives are arranged on the upper side of the fixing frame along the length direction of the fixing frame and parallel to the length direction of the housing. A second block knife that cooperates with each other is arranged on one side of each first block knife. Each second block knife is rotatably connected to the mounting frame. A rotating component for driving the second block knife to rotate is arranged on the housing.

[0019] By adopting the above technical solution, each section of the vehicle body to be sheared is sequentially moved to the upper side of the first block knife by the steering plate and contacts a plurality of first block knives simultaneously. At this time, the rotating component drives the second block knife to rotate towards the direction close to the first block knife, which is convenient for cooperating with the corresponding first block knife to shear the vehicle body into blocks simultaneously and pass through the mounting frame and fall, further facilitating the rapid shearing of scrapped vehicles and improving work efficiency.

[0020] Optionally, the rotating component includes a rotating shaft that penetrates and is fixedly connected to the same end of the second block knife away from the housing and is rotatably connected to the fixing frame. A driving rod is fixedly connected to one end of each second block knife away from the rotating shaft. A third hydraulic cylinder is hinged to one side of the housing close to the rotating shaft. The third hydraulic cylinder is hinged to the driving rod.

[0021] By adopting the above technical solution, the telescopic rod of the third hydraulic cylinder extends or contracts, so as to drive the second block knife and the rotating shaft to rotate and cut the vehicle body through the driving rod, improving work efficiency.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. The scrapped vehicle is continuously squeezed by the squeezing component and moves downward under the drive of its own gravity when the squeezing component contracts to the first shearing knife for shearing. Then, it is turned by the turning part and moved to the block component for blocking, reducing the possibility of manually driving the segmented vehicle body to move. Moreover, the squeezing component, the first shearing knife and the second shearing knife, the turning part and the block component act simultaneously, improving the shearing efficiency of the scrapped vehicle and reducing the adverse impact on work efficiency; 2. When the first shearing knife and the second shearing knife cooperate with each other to cut the scrapped vehicle into segments, the cut scrapped vehicle tilts towards the direction close to the steering plate until it contacts the inclined surface on the steering plate. The first shearing knife drives the steering plate to continue moving towards the direction close to the block component until the cut scrapped vehicle moves to the block component, facilitating further blocking. Moreover, the first shearing knife drives the steering plate to reset, facilitating the segmentation and turning of the scrapped vehicle again, improving the shearing efficiency of the scrapped vehicle and reducing the adverse impact on work efficiency; 3. The side of the connecting plate and the box body close to the second shearing knife forms a stepped shape gradually towards the direction close to the second shearing knife. When the extrusion box extrudes the scrapped automobile, the sides of multiple groups of connecting plates and the box body close to the second shearing knife extrude the scrapped automobile. At this time, the degree of extrusion of the scrapped automobile gradually increases along its own length direction. Since the second hydraulic cylinder drives the extrusion box to reciprocate, when the extrusion box moves away from the second shearing knife, the scrapped automobile moves downward, so that the degree of extrusion of the scrapped automobile when it moves to be sheared by the first shearing knife is the same, improving the working efficiency.

[0028] The following further details the present application with reference to the drawings.

[0029] The embodiment of the present application discloses a scrapped automobile decomposition fast multi-knife shearing machine. Refer to Figure 1 and Figure 2 , a scrapped automobile decomposition fast multi-knife shearing machine includes a vertical housing 1 with an open upper end. A feed hopper 11 communicating with the inside of the housing 1 and used for holding the scrapped automobile to be sheared is installed at the upper end of the housing 1, and a discharge port 12 communicating with the inside of the housing 1 is opened on one side of the lower end of the housing 1.

[0030] Refer to Figure 2 and Figure 3, an extrusion assembly 2 for extruding scrapped cars is provided on the upper side inside the housing 1, and a first shear blade 3 is provided below the extrusion assembly 2 on the side of the housing 1 away from the discharge port 12. The first shear blade 3 is horizontal and arranged along the width direction of the housing 1. The first shear blade 3 is arranged in a "V" shape that gradually inclines away from the discharge port 12 from both ends to the middle along its own length direction. In the embodiment of the present application, the included angle between both ends of the first shear blade 3 is 160°. A second shear blade 31 is fixedly connected to the side of the housing 1 close to the discharge port 12 and arranged along the width direction of the housing 1 and adapted to the first shear blade 3. The height of the second shear blade 31 is higher than the height of the upper side of the discharge port 12.

[0031] Refer to Figure 2 , Figure 3 and Figure 4 , a horizontal sliding frame 32 is fixedly connected to the side of the first shear blade 3 away from the discharge port 12. Both vertical sides of the sliding frame 32 are inserted into the inner side wall of the housing 1 and slidably connected to the housing 1 along the length direction 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 32.

[0032] A steering member for driving the segmented vehicle body to turn is provided on the sliding frame 32. The steering member includes a steering plate 34 fixedly connected to the lower side of the first shear blade 3 and arranged along the width direction of the housing 1. The side of the steering plate 34 close to the second shear blade 31 is set as an inclined surface that slopes upward and away from the discharge port 12. A block splitting assembly 4 for further shearing the segmented vehicle body is provided at the lower end outside the housing 1.

[0033] Put the scrapped car to be sheared into the feed hopper 11. The scrapped car on the side of the feed hopper 11 away from the second hydraulic cylinder 23 moves downward under its own gravity and enters the housing 1. At this time, the scrapped car is arranged along the height direction of the housing 1. The extrusion assembly 2 reciprocates to extrude the scrapped car. When the extrusion assembly 2 contracts, the extruded scrapped car moves downward under its own gravity 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 shear blade 3 to reciprocate, so as to cooperate with the second shear blade 31 to cut off the lower end of the scrapped car.

[0034] The steering plate 34 moves along with the first shearing blade 3. When the first shearing blade 3 and the second shearing blade 31 cooperate to cut the scrapped vehicle, the cut scrapped vehicle tilts towards the direction close to 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 direction close to the block splitting assembly 4 until the cut scrapped vehicle moves to the block splitting assembly 4, which facilitates the block splitting assembly 4 to further cut the segmented vehicle body into blocks. Then the first shearing blade 3 drives the steering plate to quickly reset, which is convenient for cutting and steering the scrapped vehicle again, improving the shearing efficiency of the scrapped vehicle.

[0035] The scrapped vehicle is continuously extruded by the extrusion assembly 2 and moves downward to the first shearing blade 3 under the drive of its own gravity when the extrusion assembly 2 contracts. Then it is steered by the steering part and moves to the block splitting assembly 4 for block splitting. The extrusion assembly 2, the first shearing blade 3, the second shearing blade 31, the steering part and the block splitting assembly 4 act simultaneously, improving the shearing efficiency of the scrapped vehicle.

[0036] The shape of the first shearing blade 3 enables the first shearing blade 3 to easily cooperate with the second shearing blade 31 to cut the extruded scrapped vehicle, and both sides of the first shearing blade 3 are inserted into the housing 1, thereby reducing the possibility of debris of the scrapped vehicle adhering to the side wall of the first shearing blade 3 when lubricating both sides of the first shearing blade 3.

[0037] Refer to Figure 2 and Figure 3 As shown in [relevant reference] and [relevant reference], the extrusion assembly 2 includes a horizontal extrusion box 21. The extrusion box 21 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 close to the discharge port 12 is vertical. The height of the side of the box body 211 close to the discharge port 12 is equal to the distance between the first shearing blade 3 and the inner side wall of the housing 1. The connection line between the horizontal upper side surface of the box body 211 and the vertical side surface close to the discharge port 12 slopes downward towards the side close to the discharge port 12, and a plurality of connecting plates 212 arranged in sequence for connecting the two are provided between the horizontal upper side surface of the box body 211 and the vertical side surface close to the discharge port 12. In the embodiment of the present application, three connecting plates are provided.

[0038] The connecting plate 212 includes a vertical first connecting portion 2121 on the side far from the discharge port 12 and a second connecting portion 2122 on the side close to the discharge port 12. The second connecting portions 2122 all slope downward towards the side close to the discharge port 12. In the embodiment of the present application, the included angle between the second connecting portion 2122 and the horizontal plane is 45°, and the lower sides of the second connecting portions 2122 are all located on the upper side of the first connecting portion 2121 of the adjacent connecting plate 212 and are fixedly connected to the upper side of the adjacent first connecting portion 2121.

[0039] On both vertical sides of the extrusion box 21, there are horizontally arranged guide rods 22 along the length direction of the housing 1, and the guide rods 22 are inserted into the inner side walls of the housing 1 and are slidably connected to the inner side walls of the housing 1. At the upper end of the side of the housing 1 away from the discharge port 12, a horizontal second hydraulic cylinder 23 is fixedly connected, and the telescopic rod of the second hydraulic cylinder 23 passes through the housing 1 and is fixedly connected to the extrusion box 21.

[0040] Put the scrapped vehicle to be sheared into the feed hopper 11. The scrapped vehicle on the side of the feed hopper 11 away from the second hydraulic cylinder 23 moves downward under its own gravity. At this time, the second hydraulic cylinder 23 drives the extrusion box 21 to reciprocate and extrude the scrapped vehicle, and at the same time, it does not affect the feeding in the feed hopper 11.

[0041] The extrusion box 21 is composed of a box body 211 and multiple groups of connecting plates 212, and a stepped shape gradually approaching the second shear blade 31 is formed on the side of the connecting plates 212 and the box body 211 close to the second shear blade 31. When the extrusion box 21 extrudes the scrapped vehicle, the sides of multiple groups of connecting plates 212 and the box body 211 close to the second shear blade 31 extrude the scrapped vehicle, and at this time, the degree of extrusion of the scrapped vehicle gradually increases along its own length direction.

[0042] Since the second hydraulic cylinder 23 drives the extrusion box 21 to reciprocate, when the extrusion box 21 moves away from the second shear blade 31, the scrapped vehicle moves downward, so that the extrusion degrees of each section of the scrapped vehicle when moving to be sheared by the first shear blade 3 are the same.

[0043] After the lower end of the scrapped vehicle is extruded by the extrusion box 21, it moves under its own gravity to abut against the inner side wall of the housing 1. At this time, the distance that the scrapped vehicle is extruded by the vertical side of the box body 211 close to the second shear blade 31 is equal to the height of the first shear blade 3, which is convenient for the first shear blade 3 and the second shear blade 31 to cooperate with each other and cut off the lower end of the scrapped vehicle. And at this time, one end of the vehicle body of the scrapped vehicle adjacent to the cut-off vehicle body is extruded by the vertical side of the box body 211 close to the second shear blade 31 to be adapted to the height of the first shear blade 3. Thus, each section of the scrapped vehicle is gradually extruded to be adapted to the height of the first shear blade 3 through the stepped side of the box body 211, which is convenient for shearing.

[0044] Refer to Figure 1 、 Figure 3 and Figure 4 As shown in, the block splitting assembly 4 includes a fixing frame 41 fixedly connected to the lower end of the outer side of the housing 1 close to 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, and a plurality of first block splitting blades 42 evenly distributed along the width direction of the fixing frame 41 are fixedly connected to the upper side of the fixing frame 41. In the embodiment of the present application, it is set to two, and the first block splitting blades 42 are vertical and arranged along the length direction of the fixing frame 41.

[0045] On one side of the first block cutter 42, there are vertical second block cutters 43 corresponding to the first block cutter 42 one by one. The end of the second block cutter 43 far from the housing 1 is rotatably connected to the upper side of the fixing frame 41, and a rotating assembly 5 for driving the second block cutters 43 to rotate simultaneously is provided on the housing 1.

[0046] Refer to Figure 1 and Figure 3 As shown in, the rotating assembly 5 includes a rotating shaft 51 that simultaneously passes through the end of the second block cutter 43 far from the housing 1 and is fixedly connected to the second block cutter 43. The rotating shaft 51 is horizontal and rotatably connected to the upper side of the fixing frame 41. On the upper side of the end of the second block cutter 43 close to the housing 1, there is a same driving rod 52 fixedly connected. On the side of the housing 1 close to the fixing frame 41, there is a third hydraulic cylinder 53 hinged towards the driving rod 52, and the telescopic rod of the third hydraulic cylinder 53 is hinged to the driving rod 52.

[0047] The sections of the vehicle body to be sheared are successively moved to the upper side of the first block cutter 42 by the turning plate 34 and are in contact with a plurality of first block cutters 42 simultaneously. At this time, the third hydraulic cylinder 53 drives the second block cutter 43 to rotate towards the direction close to the first block cutter 42 through the driving rod 52 and the rotating shaft 51, facilitating cooperation with the corresponding first block cutter 42 and simultaneously shearing the vehicle body into blocks. At this time, the block-shaped vehicle body passes through the mounting frame and drops, completing the shearing of the scrapped vehicle.

[0048] On the outer sides of the first hydraulic cylinder 33 and the second hydraulic cylinder 23, there are mounting boxes 6 sleeved and fixedly connected. When installing the first hydraulic cylinder 33 and the second hydraulic cylinder 23, the mounting boxes 6 are inserted into the housing 1. On the housing 1, there are mounting pins 61 corresponding to both sides of the mounting box 6 one by one and 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 box 6.

[0049] A high-pressure hydraulic pump (not shown in the figure) and a low-pressure hydraulic pump (not shown in the figure) are connected to the first hydraulic cylinder 33, the second hydraulic cylinder 23, and the third hydraulic cylinder 53, 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 a control host (not shown in the figure).

[0050] 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 sensors detect the pressure values received. When the pressure value reaches the set maximum pressure value, the control host drives the low-pressure hydraulic pump to stop working, so as to drive 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 values detected by the pressure sensors continue to rise, facilitating rapid shearing and extrusion and improving work efficiency.

[0051] When the telescopic rods of the first hydraulic cylinder 33, the second hydraulic cylinder 23, and the third hydraulic cylinder 53 contract until the pressure value detected by the pressure sensor drops to the set maximum pressure value, the control host drives the low-pressure hydraulic pump to start working, so as to drive the telescopic rods of the corresponding first hydraulic cylinder 33, second hydraulic cylinder 23, and third hydraulic cylinder 53 to contract simultaneously through the high-pressure hydraulic pump and the low-pressure hydraulic pump, thereby saving energy and achieving the effect of energy-saving acceleration.

[0052] The implementation principle of a rapid multi-knife shearing machine for disassembling scrapped automobiles in an embodiment of the present application is as follows: The scrapped automobile is continuously squeezed by the squeezing box 21 and moves downward under the drive of its own gravity when the squeezing box 21 contracts to be sheared at the first shearing knife 3, and then is turned by the turning plate 34 and moves to the fixing frame 41 for block division. The squeezing box 21, the first shearing knife 3, the second shearing knife 31, the turning plate 34, the first block division knife 42, and the second block division knife 43 act simultaneously until the scrapped automobile is sheared completely.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
