Description

Technical Field

[0001] This application relates to the technical field of steel scrap recycling, and in particular to a steel pipe scrap crushing device. Background Technology

[0002] Currently, steel pipe fittings or other mechanical parts are produced during the processing of steel products. These scraps can be recycled and reused. At the same time, scrapped or non-compliant steel pipes can also be recycled and reused.

[0003] When recycling scrap materials and steel pipe waste, the relevant technologies compress and pack the loose waste materials, stack them into piles to reduce the floor space occupied, facilitate subsequent transportation, and also make it easier to fill the furnace when it is put into smelting.

[0004] Current briquetting machines use an extrusion plate to compress steel pipe scrap in an extrusion trough into a cake shape, and then use another hydraulic cylinder to finally compress the cake-shaped scrap into a rectangular shape.

[0005] Regarding the aforementioned technologies, this application believes that in order to ensure the density of the extruded waste, the steel pipe waste needs to fill the extrusion groove as much as possible. This ensures the efficiency of the briquetting machine while also ensuring the density of the extruded waste product. When the extrusion groove is filled with steel pipe waste and is being extruded, there is a situation where adjacent steel pipes are extruded and splashed out of the extrusion groove, which may pose a safety hazard to the environment around the briquetting machine. Summary of the Invention

[0006] In order to reduce the situation where steel pipes splash out of the extrusion groove during the extrusion of steel pipe scrap, this application provides a steel pipe scrap crushing device.

[0007] The steel pipe scrap compaction equipment provided in this application adopts the following technical solution:

[0008] A steel pipe scrap crushing device includes a machine body with an extrusion groove. An extrusion plate is rotatably mounted on the machine body, and the rotation shaft is horizontally positioned. A front baffle, a first baffle, and a second baffle are rotatably mounted on the machine body. The front baffle is located at the top of the side wall of the extrusion groove, directly opposite the rotation shaft of the extrusion plate. The first baffle and the second baffle are located on both sides of the front baffle. When the first baffle, the front baffle, and the second baffle are all rotated to a vertical position, they block the extrusion groove in three consecutive directions above. A first hydraulic cylinder is mounted on the machine body. One end of the piston rod of the first hydraulic cylinder is hinged to the front baffle, and one end of the cylinder body is hinged to the machine body and simultaneously slidably connected relative to the machine body. During sliding, it slides horizontally in the direction away from or towards the front baffle.

[0009] By adopting the above technical solution, the extrusion trough is filled with steel pipe scrap. The first baffle, front baffle, and second baffle are rotated, and the extrusion plate completely covers the top and sides of the extrusion trough. The extrusion plate then extrudes the scrap, blocking any splashing scrap and reducing the likelihood of steel pipe scrap flying out of the extrusion trough, thus ensuring the safety of the surrounding processing environment. When the front baffle is rotated to a vertical position, the first hydraulic cylinder moves to an inclined position relative to the front baffle, thus forming a triangular shape with the vertical front baffle, which is the most stable state. When the front baffle is retracted, one end of the first hydraulic cylinder moves towards the machine body, and the front baffle retracts to a horizontal position, still forming a stable triangular shape with the hydraulic cylinder, ensuring the stability of the baffle after placement.

[0010] Optionally, a flap is rotatably mounted on the machine body, with the rotating shaft coaxial with the rotating shaft of the front baffle. The flap is L-shaped. In the retracted state, the horizontal part of the flap is embedded in the bottom of the machine body, and the wall thickness of the vertical part of the flap is the same as the wall thickness of the extrusion groove and is inserted into the groove wall of the extrusion groove. A support rod is provided on the front baffle, with one end of the support rod fixedly connected to the front baffle and the other end abutting against the flap. In the horizontal state of the front baffle, the end of the support rod abuts against the outer wall of the vertical part of the flap.

[0011] By adopting the above technical solution, when the first hydraulic cylinder pulls the front baffle to a horizontal state and continues to pull, the front baffle is tilted downwards. The support rod, together with the front baffle, lifts the flip plate. The compressed waste material is lifted by the flip plate and then flipped out of the extrusion groove, which facilitates the subsequent transportation of the waste material, improves processing efficiency, and makes full use of the first hydraulic cylinder and the front baffle.

[0012] Optionally, a support plate is fixed on the machine body, and a second hydraulic cylinder and a sliding plate are provided on the support plate. The second hydraulic cylinder is horizontally fixed on the support plate and its piston end is fixedly connected to the sliding plate. The sliding plate is slidably mounted on the support plate, and one end of the body of the first hydraulic cylinder is hinged to the sliding plate.

[0013] By adopting the above technical solution, the second hydraulic cylinder, in conjunction with the support plate, enables the first hydraulic cylinder to move stably in the horizontal direction, providing the necessary starting position for the first hydraulic cylinder to drive the front baffle to rotate or drive the flip plate to rotate.

[0014] Optionally, a connecting rod is provided on the outer wall of the machine body. The connecting rod is horizontally arranged and perpendicular to the rotation axis between the first baffle and the machine body. The connecting rod rotates relative to the machine body. A drive gear is fixed on the connecting rod, and a rack is fixed on the slide plate. The rack and the gear mesh. The rotation axis between the first baffle and the machine body meshes with the connecting rod, and the rotation axis between the second baffle and the machine body also meshes with the connecting rod.

[0015] By adopting the above technical solution, the slide plate drives the connecting rod to rotate through the rack and pinion and the drive gear. The connecting rod drives the first baffle and the second baffle to rotate, which makes full use of the second hydraulic cylinder and the slide plate. When the second hydraulic cylinder is activated to transport the first hydraulic cylinder to the appropriate position, the second hydraulic cylinder also realizes the flipping of the first baffle and the second baffle. At the same time, the first hydraulic cylinder also drives the front baffle, which can realize the effect of flipping the front baffle, the first baffle and the second baffle to the vertical position at the same time, thus improving work efficiency.

[0016] Optionally, the front baffle is provided with a baffle strip and a spring. The front baffle has a receiving groove. One end of the baffle strip is inserted into the receiving groove, and the spring is located in the receiving groove. One end of the spring is fixedly connected to the bottom of the receiving groove, and the other end is fixedly connected to the baffle strip. The length direction of the baffle strip and the receiving groove are both set along the direction of the line connecting the first baffle and the second baffle. When the front baffle is vertical, the baffle strip is located on the side wall of the front baffle facing the extrusion plate. The top surface of the baffle strip is an inclined surface, and the inclined direction is inclined downwards away from the front baffle.

[0017] By adopting the above technical solution, when the steel pipe scrap is being squeezed, as the extrusion plate falls, the steel pipe scrap will move towards the front baffle. When it is blocked by the horizontal obstruction of the front baffle, it will tend to overflow upwards. At this time, it is blocked by the baffle bar. The extrusion plate falls down along the slope of the baffle bar and squeezes the baffle bar back into the receiving groove, thereby completely pressing down the steel pipe scrap in the extrusion groove. The presence of the baffle bar plays a role in blocking the upward overflow of the steel pipe scrap.

[0018] Optionally, the top surface of the horizontal part of the flip plate is lower than the plane where the bottom of the extrusion groove is located. A protrusion is fixed on the extrusion plate. When the extrusion plate is horizontal, the protrusion is located directly above the horizontal part of the flip plate. The cross-sectional shape of the groove formed by the horizontal part of the flip plate and the extrusion groove is the same as the cross-sectional shape of the protrusion, and the size is smaller than the cross-sectional shape of the protrusion.

[0019] By adopting the above technical solution, the setting of the horizontal position of the flip plate and the presence of the protrusions, after the steel pipe scrap is squeezed into blocks, protrusions and depressions will be formed on the surface of the block scrap. The protrusions can be inserted into the depressions, which facilitates the subsequent transportation of block scrap and reduces the occurrence of side slippage of adjacent block scrap during transportation.

[0020] Optionally, the flap is positioned near the support plate in the extrusion groove.

[0021] By adopting the above technical solution, since only one first hydraulic cylinder is set, the force application point of the front baffle is only at one end of the front baffle. The flap is set near the support plate, thus close to the first hydraulic cylinder, which shortens the lever arm of the front baffle, reduces the torque on the front baffle, and reduces the phenomenon of the front baffle itself twisting.

[0022] Optionally, an elastic pad is fixed to the end of the support rod, the elastic pad is looped around the outer wall of the support rod, and the elastic pad abuts against the vertical part of the flap.

[0023] By adopting the above technical solution, the presence of the elastic pad can reduce the rigid collision between the support rod and the flap, extend the service life of the support rod, and reduce the wear of the support rod.

[0024] Optionally, an overlap strip is provided on the side wall of the extrusion plate away from the extrusion groove. One end of the overlap strip is fixedly connected to the extrusion plate, and the other end is cantilevered in the direction away from the extrusion plate. When the extrusion plate is horizontal, the end of the overlap strip away from the extrusion plate overlaps the top of the front baffle.

[0025] By adopting the above technical solution, the presence of the lap strip plays a limiting role in the extrusion plate, ensuring that the extrusion plate can extrude the steel pipe scrap into place without over-extruding. At the same time, after the extrusion plate is placed in place, the lap strip also plays a supporting role in the extrusion plate, reducing the wear and tear on the equipment driving the extrusion plate.

[0026] Optionally, when the end of the support rod is in contact with the flap, the angle between the front baffle and the vertical part of the flap is an obtuse angle.

[0027] By adopting the above technical solution, when the second hydraulic cylinder lifts the flap plate through the front baffle and support rod, the flap plate carries the compressed steel pipe scrap out of the extrusion groove. At this time, the front baffle is tilted downward, which is just right to receive the falling block scrap. The block scrap is blocked by the baffle during the falling process, thereby reducing the impact and wear of the block steel scrap on the ground or the block scrap receiving object.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The presence of the front baffle, the first baffle, and the second baffle effectively prevents the splashing of steel pipe scrap in the extrusion groove;

[0030] 2. The cooperation of the first hydraulic cylinder and the second hydraulic cylinder not only provides rotational power to the front baffle, the first baffle and the second baffle, but also works with the support rod to provide rotational power to the flap, thus making full use of resources.

A first baffle 13, a front baffle 2, and a second baffle 14 are rotatably arranged on the top of the machine body 1. The extrusion plate 12, the first baffle 13, the front baffle 2, and the second baffle 14 completely block the top of the extrusion groove 11 in four directions. When the extrusion plate 12 extrudes the steel pipe scrap in the extrusion groove 11, it reduces the phenomenon of steel pipe scrap splashing out of the extrusion groove 11, ensuring the safety of the surrounding processing environment and ensuring the density of the compressed scrap.

A support rod 21 is provided on the front baffle 2. One end of the support rod 21 is fixedly connected to the front baffle 2, and the other end is fitted with an elastic pad 211. The elastic pad 211 is made of rubber and abuts against the outer wall of the vertical part of the flip plate 4. When the end of the support rod 21 abuts against the flip plate 4, the included angle between the front baffle 2 and the vertical part of the flip plate 4 is an obtuse angle.

[0042] refer to Figure 2 and Figure 3When the first baffle 13 is flipped to a vertical position, its sidewall is flush with the inner wall of the extrusion groove 11. When the second baffle 14 is flipped to a vertical position, its sidewall is flush with the inner wall of the extrusion groove 11.

[0043] The implementation principle of the steel pipe scrap crushing device in this application embodiment is as follows: The second hydraulic cylinder 32 is started, and the first hydraulic cylinder 31 is started at the same time. The first hydraulic cylinder 31 rotates the front baffle 2 to a vertical position. The second hydraulic cylinder 32 rotates the connecting rod 5 through the cooperation of the rack 34 and the drive gear 6. The connecting rod 5 then rotates the first baffle 13 and the second baffle 14 to a vertical position. The extrusion plate 12 is started to extrude the steel pipe scrap in the extrusion groove 11. After extrusion is completed, the second hydraulic cylinder 32 is reset, and the first hydraulic cylinder 31 is also reset.
