Description

Technical Field

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

[0002] When crushing scrap steel, the scrap steel to be crushed is usually conveyed upwards by a conveyor and enters the crusher through the feed inlet. At this time, the upper side of the rotor disk rotates towards the feed inlet and drives the scrap steel entering the crusher to move towards the lower side of the rotor disk. Thus, under the impact of the high-speed rotating hammers on the rotor disk, it is crushed into small pieces of metal until the scrap steel crushing is completed.

[0003] In related technologies, the crusher is fed by an inclined conveyor belt. As a result, the scrap steel has an upward inertia when it enters the crusher. Since the upper side of the rotor disc always rotates towards the feed inlet, the scrap steel entering the crusher may easily fly out of the feed inlet under the drive of the rotor disc. The scrap steel that flies out needs to be collected manually, which in turn has an adverse effect on the scrap steel crushing efficiency. Utility Model Content

[0004] In order to reduce the adverse effects on scrap steel crushing efficiency, this application provides a scrap steel crushing device.

[0005] The scrap steel crushing device provided in this application adopts the following technical solution:

[0006] A scrap steel crushing device includes a crusher body, a feed inlet at one upper end of the crusher body, a feed hopper on the side of the crusher body near the feed inlet, a conveying frame connected to the lower side of the feed hopper and facing the crusher body and blocking the feed inlet, an installation component connected to the crusher body on the conveying frame, and a conveying component for driving the scrap steel in the feed hopper into the crusher body.

[0007] By adopting the above technical solution, the conveyor frame and feed hopper are installed on the crusher body through the installation components. The feed inlet is blocked by the conveyor frame, making it difficult for scrap steel entering the crusher body to fly out through the feed inlet. This reduces the possibility of manually collecting the scrap steel that flies out and continuously conveys the scrap steel to the feed hopper. At this time, the lower side of the feed hopper is connected to the conveyor frame. The scrap steel entering the conveyor frame is pushed into the crusher body through the feed inlet by the conveying components. This facilitates feeding the crusher body without affecting the continuous feeding to the feed hopper, further reducing the adverse effects on the scrap steel crushing efficiency.

[0008] Optionally, the mounting assembly includes a first mounting plate fixedly connected to the side of the conveyor frame near the feed inlet, and a second mounting plate corresponding to the first mounting plate is fixedly connected to the upper side of the crusher body near the end of the conveyor frame. The first mounting plate and the second mounting plate are fixedly connected by bolts.

[0009] By adopting the above technical solution, the conveyor frame is driven to move until the first mounting plate and the second mounting plate abut against each other. The first mounting plate and the second mounting plate are fixed by bolts, which makes it easier to install the conveyor frame on the crusher body and further reduces the adverse effects on the scrap steel crushing efficiency.

[0010] Optionally, the conveying assembly includes a blocking plate that is slidably connected to the upper side inside the conveying frame and can block the lower side of the feed hopper. A push plate is fixedly connected to one end of the blocking plate near the feed inlet, which is arranged along the height direction of the conveying frame. The side wall of the push plate contacts the inner side wall of the conveying frame. The conveying frame is provided with a driving member that drives the push plate to move towards the feed inlet.

[0011] By adopting the above technical solution, the scrap steel is located in the feed hopper. The driving component drives the sealing plate and the pushing plate to move away from the feed inlet. At this time, the lower side of the feed hopper is connected to the conveying frame. The scrap steel in the feed hopper enters the conveying frame. The driving component drives the pushing plate to move the sealing plate closer to the feed inlet and pushes the scrap steel in the conveying frame to move into the crusher body. At this time, the sealing plate partially or completely blocks the lower side of the feed hopper. Thus, the driving component drives the sealing plate and the pushing plate to move back and forth in the conveying frame and push the scrap steel in the conveying frame into the crusher body. At the same time, it does not affect the feeding in the feed hopper and reduces the adverse effects on the scrap steel crushing efficiency.

[0012] Optionally, the driving component includes a hydraulic cylinder installed at the end of the conveying frame away from the feed inlet, and the telescopic rod of the hydraulic cylinder is fixedly connected to the side wall of the push plate.

[0013] By adopting the above technical solution, the telescopic rod of the hydraulic cylinder continuously shortens or extends, thereby driving the push plate and the sealing plate to move back and forth in the conveying frame, which facilitates feeding the crusher body and reduces the adverse effects on the scrap steel crushing efficiency.

[0014] Optionally, a travel limiter is installed at the end of the sealing plate away from the feed inlet.

[0015] By adopting the above technical solution, the hydraulic cylinder drives the push plate and the blocking plate to move in the conveying frame, and the stroke limiter limits the push plate in the length direction of the conveying frame, reducing the possibility that the scrap steel in the feed hopper will move to the side of the push plate close to the hydraulic cylinder and become difficult to remove. At the same time, it reduces the possibility that too much scrap steel in the conveying frame will cause material jamming inside the crusher body, thus reducing the adverse effects on the scrap steel crushing efficiency.

[0016] Optionally, the crusher body is provided with a plurality of rotor discs arranged along the width direction of the crusher body, and the rotor discs rotate in a direction away from the feed inlet.

[0017] By adopting the above technical solution, the rotation direction of the rotor disc causes the scrap steel entering the crusher body to move along the upper side of the rotor disc away from the feed inlet under the drive of the rotor disc until it moves and is crushed along the circumference of the rotor disc, reducing the possibility of scrap steel accumulating at the feed inlet and reducing the adverse effects on the scrap steel crushing efficiency.

[0018] Optionally, the distance between the inner wall of the crusher body on the side closer to the feed inlet and the upper side of the rotor disc is greater than the distance between the inner wall of the crusher body on the side farther from the feed inlet and the upper side of the rotor disc.

[0019] By adopting the above technical solution, the distance between the inner wall of the crusher body and the edge of the rotor disc increases the space near the feed inlet of the crusher body, reducing the possibility of scrap steel accumulating at the feed inlet and reducing the adverse effects on the scrap steel crushing efficiency.

[0020] Optionally, the conveyor frame is set horizontally.

[0021] By adopting the above technical solution, the horizontal setting of the conveyor frame facilitates the pusher plate to push the scrap steel into the crusher body, and at the same time facilitates the control of the amount of scrap steel pushed into the crusher body at one time, reducing the adverse effects of too much or too little scrap steel pushed in at one time on the scrap steel crushing efficiency.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By blocking the feed inlet with the conveyor frame, the scrap steel entering the crusher body is difficult to fly out through the feed inlet, reducing the possibility of manually collecting the scrap steel that flies out. The scrap steel is continuously conveyed to the feed hopper. At this time, the lower side of the feed hopper is connected to the conveyor frame. The scrap steel entering the conveyor frame is pushed into the crusher body through the feed inlet by the conveyor assembly. This makes it easy to feed the crusher body without affecting the continuous feeding to the feed hopper, further reducing the adverse effects on the scrap steel crushing efficiency.

[0024] 2. The blocking plate and the push plate are driven by the drive unit to move away from the feed inlet. At this time, the lower side of the feed hopper is connected to the conveying frame. The scrap steel in the feed hopper enters the conveying frame. The drive unit drives the push plate to move the blocking plate closer to the feed inlet and pushes the scrap steel in the conveying frame to move into the crusher body. At this time, the blocking plate partially or completely blocks the lower side of the feed hopper. Thus, the blocking plate and the push plate are driven by the drive unit to move back and forth in the conveying frame and push the scrap steel in the conveying frame into the crusher body. At the same time, it does not affect the feeding in the feed hopper and reduces the adverse effect on the scrap steel crushing efficiency.

[0025] 3. The rotation direction of the rotor disc causes the scrap steel entering the crusher body to move along the upper side of the rotor disc away from the feed inlet under the drive of the rotor disc until it moves along the circumference of the rotor disc and is crushed. In addition, the distance between the inner wall of the crusher body and the edge of the rotor disc increases the space of the crusher body near the feed inlet, reducing the possibility of scrap steel accumulating at the feed inlet.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] This application discloses a scrap steel crushing device. (Refer to...) Figure 1 and Figure 2A scrap steel crushing device includes a crusher body 1, and a horizontal feed inlet 11 that communicates with the interior of the crusher body 1 is provided on the upper side of one end of the crusher body 1.

[0033] Inside the crusher body 1, a horizontal rotor shaft 12 is rotatably connected to the lower side and is arranged along the width direction of the crusher body 1. Multiple vertical rotor discs 13 are evenly distributed along the length direction of the rotor shaft 12 and are fixedly connected to the rotor shaft 12. The rotor shaft 12 always drives the rotor discs 13 to rotate in a clockwise direction.

[0034] The distance between the inner wall of the crusher body 1 away from the feed inlet 11 and the axis of the rotor disk 13 gradually increases from bottom to top. The distance between the inner wall of the crusher body 1 near the feed inlet 11 and the axis of the rotor disk 13 also gradually increases from bottom to top. The distance between the inner wall of the crusher body 1 directly opposite the feed inlet 11 and the axis of the rotor disk 13 is the largest.

[0035] Reference Figure 1 and Figure 3 A horizontal feed hopper 2, higher than the feed inlet 11, is provided on the side of the crusher body 1 near the feed inlet 11. A feeding port 21 is provided on one side of the feed hopper 2, and the cross-sectional area of ​​the feed hopper 2 decreases from top to bottom. A horizontal conveyor frame 3, facing the feed inlet 11, is fixedly connected and communicated with the lower side of the feed hopper 2. A support platform 31 is installed on the lower side of the conveyor frame 3. An installation assembly 4, fixedly connected to the crusher body 1, is provided on the side of the conveyor frame 3 near the feed inlet 11, and a conveying assembly 5 is provided in the conveyor frame 3 to drive the scrap steel in the conveyor frame 3 into the crusher body 1.

[0036] By installing the assembly 4, the conveyor frame 3 and the feed hopper 2 are installed on the crusher body 1, thereby blocking the feed inlet 11 through the conveyor frame 3, making it difficult for the scrap steel entering the crusher body 1 to fly out through the feed inlet 11. The workers continuously convey the scrap steel to the feed hopper 2 through the feeding port 21. At this time, the lower side of the feed hopper 2 is connected to the conveyor frame 3. The conveyor assembly 5 pushes the scrap steel entering the conveyor frame 3 into the crusher body 1 through the feed inlet 11, which facilitates feeding the crusher body 1 without affecting the continuous feeding to the feed hopper 2.

[0037] The rotation direction of the rotor disc 13 causes the scrap steel entering the crusher body 1 to move along the upper side of the rotor disc 13 away from the feed inlet 11 under the drive of the rotor disc 13 until it moves around the rotor disc 13 and is crushed. The distance between the inner wall of the crusher body 1 and the edge of the rotor disc 13 increases the space of the crusher body 1 near the feed inlet 11, reducing the possibility of scrap steel accumulating at the feed inlet 11.

[0038] The conveyor frame 3 is set horizontally, which makes it easy for the pusher plate 54 to push the scrap steel into the crusher body 1. At the same time, it is easy to control the amount of scrap steel pushed into the crusher body 1 at one time, reducing the adverse effects of too much or too little scrap steel pushed in at one time on the scrap steel crushing efficiency.

[0039] Reference Figure 1 Mounting assembly 4 includes a vertical first mounting plate 41 fixedly connected to one end of the conveyor frame 3 near the feed inlet 11. The middle of the first mounting plate 41 is located on the upper side outside the conveyor frame 3, and both ends of the first mounting plate 41 are bent downwards at right angles. A vertical second mounting plate 42, which is adapted to the first mounting plate 41 and has the same shape, is fixedly connected to one end of the crusher body 1 near the feed inlet 11. The first mounting plate 41 and the second mounting plate 42 abut against each other and are fixedly connected by bolts.

[0040] The drive conveyor frame 3 is moved to abut against the first mounting plate 41 and the second mounting plate 42. The first mounting plate 41 and the second mounting plate 42 are fixed by bolts, thereby installing the conveyor frame 3 on the crusher body 1.

[0041] Reference Figure 3 and Figure 4 The conveying assembly 5 includes a horizontal sealing plate 51 located on the upper side inside the conveying frame 3 and arranged along the length of the conveying frame 3. The sealing plate 51 can block the lower side of the feed hopper 2. The upper sides of the vertically arranged sides of the conveying frame 3, which are close to each other, are fixedly connected to abutment rods 52 arranged along the length of the conveying frame 3. The upper side of the abutment rods 52 is set as an inclined surface that slopes downward towards the side that is close to each other. The upper side of the sealing plate 51 contacts and slides with the lower side of the abutment rods 52. A travel limiter 53 is installed at the end of the sealing plate 51 away from the feed inlet 11.

[0042] Reference Figure 3 and Figure 4 A vertical push plate 54, integrally formed with the sealing plate 51, is fixedly connected to the lower side of the sealing plate 51 near the feed inlet 11. The side walls of the push plate 54 are in contact with the inner side wall of the conveying frame 3. The conveying frame 3 is provided with a driving component 55 that drives the push plate 54 to move the sealing plate 51. The driving component 55 includes a horizontal hydraulic cylinder 551 located on the side of the conveying frame 3 away from the feed inlet 11 and facing the crusher body 1. A support seat 552 located on the lower side of the conveying frame 3 is installed inside the end of the conveying frame 3 away from the feed inlet 11.

[0043] Both sides of the hydraulic cylinder 551 are fixedly connected to arc-shaped plates 553. The side of the arc-shaped plates 553 that is far apart from each other is fixedly connected to a horizontal mounting rod 554 that faces the side that is far apart from each other. Both sides of the support base 552 are provided with mounting holes 5521 that open upwards and correspond one-to-one with the mounting rods 554. The upper end of the mounting hole 5521 is adapted to the mounting rod 554, and the lower end area of ​​the mounting hole 5521 is larger than the cross-sectional area of ​​the mounting rod 554. The mounting rods 554 are all inserted into the corresponding mounting holes 5521.

[0044] Each mounting hole 5521 has a mounting ring 555 inserted into its lower end, which is sleeved on the outside of the mounting rod 554. The outer diameter of the mounting ring 555 is adapted to the lower end of the mounting hole 5521. The ends of the mounting rods 554 that are far apart from each other are threaded with screws 556 to limit the mounting ring 555, reducing the possibility of the mounting ring 555 falling off the end of the mounting rod 554. The hydraulic cylinder 551 is mounted on the support base 552 via the mounting rod 554 and the mounting ring 555, and the telescopic rod of the hydraulic cylinder 551 is fixedly connected to the push plate 54.

[0045] The scrap steel is located in the feed hopper 2. The hydraulic cylinder 551 drives the sealing plate 51 and the push plate 54 to move away from the feed inlet 11. At this time, the lower side of the feed hopper 2 is connected to the conveying frame 3. The scrap steel in the feed hopper 2 enters the conveying frame 3. The hydraulic cylinder 551 drives the push plate to move the sealing plate 51 closer to the feed inlet 11 and pushes the scrap steel in the conveying frame 3 to move into the crusher body 1. At this time, the sealing plate 51 partially or completely blocks the lower side of the feed hopper 2. Thus, the telescopic rod of the hydraulic cylinder 551 continuously shortens or extends, driving the push plate 54 and the sealing plate 51 to reciprocate in the conveying frame 3. At this time, the stroke limiter 53 limits the push plate 54 in the length direction of the conveying frame 3, which facilitates the feeding of the crusher body 1 without affecting the feeding in the feed hopper 2, until the scrap steel is crushed.

[0046] The implementation principle of a scrap steel crushing device according to an embodiment of this application is as follows: a conveying frame 3 and a feeding hopper 2 are installed on the crusher body 1, thereby blocking the feeding port 11 through the conveying frame 3, making it difficult for the scrap steel entering the crusher body 1 to fly out through the feeding port 11. The extension rod of the hydraulic cylinder 551 continuously shortens or extends, driving the push plate 54 and the blocking plate 51 to move back and forth in the conveying frame 3, which facilitates the feeding of the crusher body 1. Moreover, when the push plate feeds the crusher body 1, it does not affect the workers from feeding the hopper 2 through the feeding port 21 until the scrap steel crushing is completed.

[0047] 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.
