Description

Technical Field

[0001] The utility model relates to an upstream and downstream transportation device for a scrap metal crusher, belonging to the technical field of metal crushers. Background Art

[0002] The description in this section merely provides background information related to the disclosure of the present utility model and does not constitute prior art.

[0003] Large scrap metal crusher is a new type of high-efficiency metal crusher. Its working principle is that under the continuous drive of high-speed and high-torque motors, the hammers on the crusher rotor take turns to hit the scrap metal entering the cavity. Under the strong impact, the scrap steel is torn and squeezed into broken metal of a certain specification, and then processed by sorting equipment to obtain broken steel / aluminum / copper and other metals with higher purity. There are multiple transportation processes before and after the metal crushing process, and multiple transportation links directly affect the processing efficiency of the crusher.

[0004] First of all, during the loading process, the material that can be fed into the upper feeding conveyor of the scrap metal crushing line needs to be lifted and fed into the scrap metal crusher for crushing. Since the loading process is usually completed by a steel grabber, the falling material is often uncontrollable and often falls to the periphery of the loading area, resulting in inconvenience for personnel to enter when repairing the upper feeding conveyor of the scrap metal crushing line. There are even cases where the falling material smashes the feeding section of the upper feeding conveyor of the scrap metal crushing line. In extreme cases, explosions may occur, resulting in irregular movement of metal and personal injury to on-site workers.

[0005] Secondly, after the initial crushing of the metal and before the magnetic separation, the scrap metal is generally required to be transported by a vibrating conveyor. Metal wear will occur during operation and regular maintenance and replacement are required. The existing part for transporting scrap metal after crushing has a more complicated structure due to the presence of a vibration motor, etc., and is therefore not easy to replace and maintain, and may cause the scrap metal to leak during transportation.

[0006] There is currently no upstream and downstream transportation device for scrap metal crushers that can solve the above problems. Utility Model Content

[0007] The utility model aims to provide an upstream and downstream transport device for a scrap metal crusher, which can avoid splashing and leakage of scrap metal and is convenient for disassembly, assembly and maintenance.

[0008] In order to achieve the above-mentioned purpose, the utility model discloses the following upstream and downstream transportation device for a scrap metal crusher, which is used to transport scrap metal between the upstream and downstream of the crusher, and includes:

The vibration motor is fixed to the second steel structure frame, and the vibration output end of the vibration motor is arranged toward the bottom of the vibration plate frame.

[0011] Furthermore, it comprises a plurality of second steel frames extending perpendicular to the second direction, each of the second steel frames corresponds to one spring, and the second steel frames are connected by transverse and / or oblique reinforcing brackets.

[0012] Furthermore, each post-crushing transportation mechanism includes four of the second steel frames and four of the springs.

[0013] Furthermore, it also includes a head protection cover, which covers at least a portion of the top of the crusher and the top of the downstream of the pre-crushing transportation mechanism.

[0014] Furthermore, the head protection cover includes a plurality of square grids extending along the first direction and arranged in an equidistant array.

[0015] Furthermore, the feeding belt includes a machine chain plate, a machine sprocket and a pin shaft, the machine chain plate includes a pin barrel for being penetrated by the pin shaft, so that a plurality of the machine chain plates are connected in series along a first direction, and the machine sprocket is fixedly arranged on both sides of the machine chain plate.

[0016] Furthermore, a guide plate extending perpendicular to the first direction is further provided between the machine sprocket and the machine chain plate to limit the scrap metal from separating from the machine chain plate.

The following describes the implementation method of the present utility model based on its overall structure.

[0031] See also Figure 1-2 , is a scrap metal crusher upstream and downstream transportation device of this embodiment, used to transport scrap metal between the upstream and downstream of the crusher, including:

[0032] The pre-crushing transport mechanism 1 comprises a first steel frame 11, a feeding belt 12, side shields 13 and a front shield 14. The feeding belt 12 is fixed on the first steel frame 11 and extends along a first direction. The feeding belt 12 comprises a pair of mirror-image side shields 13 on both sides perpendicular to the first direction. The feeding belt comprises a front shield 14 at the most upstream end in the first direction, which is the same height as the side shield 13. Both sides of the front shield 14 are fixedly connected to the pair of side shields 13 respectively.

[0033] The post-crushing transportation mechanism 2 includes a second steel frame 21, a vibration plate frame 22, a vibration motor 23 and a spring 24. The vibration plate frame 21 extends along the second direction. One end of the plurality of springs 24 abuts against the bottom edge of the vibration plate frame 22, and the other end is fixed on the second steel frame 21. The vibration motor 23 is fixed on the second steel frame 21, and the vibration output end of the vibration motor 23 is arranged toward the bottom of the vibration plate frame 22.

[0034] Through the above structure, when in use, the staff only needs to place the scrap metal on the upstream of the pre-crushing transport mechanism 1 away from the crusher along the first direction, and under the drive of the external motor, drive the feeding belt 12 to start running along the first direction, and the scrap metal can be transported from the upstream to the downstream crusher entrance along the first direction without stopping, until all the scrap metal is transported to the crusher and the scrap metal crushing process begins. Among them, the loading process before transportation is usually completed by a steel grabber. Due to the uncontrollable falling of the material, the falling material often falls to the periphery of the loading area. In this embodiment, since the side shields 13 and the front shield 14 with a certain height physically shield most of the upper area of ​​the feeding belt 12 along the first direction, some of the scrap metal falls to the position of the side shields 13 and the front shield 14 around the feeding belt 12, and can slide back to the feeding belt 12, thereby avoiding the situation where the falling material is scattered to the periphery through the feeding belt 12. During the processing, some scrap metal fragments may be ejected from the position of the crusher close to the side of the pre-crushing transport mechanism 1 and splashed onto the pre-crushing transport mechanism 1 area. Similarly, most of the splashed scrap metal can slide back onto the feeding belt 12 after falling to the side guards 13 and the front guards 14 around the feeding belt 12. That is to say, in this embodiment, the feeding belt 12 is surrounded and protected by the side guards 13 and the front guards 14, reducing the possibility of scrap metal scattering around the feeding belt 12.

[0035] After the scrap metal has been initially processed by the crusher, the powdered scrap metal can fall onto the post-crushing transport mechanism 2, and then the vibration motor 23 is started and directly drives the vibration plate frame 22 above it to start vibrating. At this time, since the vibration plate frame 22 has a certain downslope toward the downstream in the second direction, the scrap metal can be moved downstream in the second direction. During the movement, the scrap metal vibrated is evenly spread out to facilitate further magnetic separation operations. The vibration plate frame 22 in this embodiment can be abutted and buffered by multiple springs 24 at the bottom of the vibration plate frame 22 during the force vibration process, thereby avoiding equipment wear caused by excessive vibration force, and the springs 24 are connected to the second steel structure frame 21 and are disposed at the edge corners of the vibration plate frame 22, which can achieve a relatively stable support effect for the vibration plate frame 22. The combination relationship of the second steel structure frame 21, the springs 24 and the vibration plate frame 22 in the above-mentioned structure is simple, and easy to disassemble and maintain.

[0036] Furthermore, if Figure 1 As shown, the first steel structure frame 11 is configured to include a plurality of tracks extending along a first direction, and a track system with a bracket composed of a plurality of tracks arranged equidistantly perpendicular to the first direction, wherein the first steel structure frame 11 can follow and extend in the first direction at different heights, angles or directions according to site needs, that is, the first steel structure frame 11 can be covered with a tortuous or straight feeding belt 12 to the top. The side shield 13 is configured to be a rectangular geometric body with a right angle in cross section, wherein the surface of one right angle side is attached to both sides of the feeding belt 12, so that the scrap metal that bounces to both sides of the feeding belt 12 can be effectively blocked and will not leak to the ground adjacent to both sides of the feeding belt 12. The front shield 14 is configured to be a regular rectangular geometric body, and the highest point of the front shield 14 is consistent with the highest point of the side shield 13, so that the two side shields 13 and one front shield 14 form a group of U-shaped enclosed spaces that are similar to the cover body, effectively forming a protective effect on the periphery of the feeding belt 12. As shown Figure 2 As shown, the post-crushing transport mechanism 2 of this embodiment includes a plurality of second steel frames 21 extending perpendicularly to the second direction, each second steel frame 21 corresponds to a spring 24, and the second steel frames 21 are connected by transverse and / or oblique reinforcing brackets. Specifically, a total of four second steel frames 21 and four springs 24 are included. That is to say, the four groups of second steel frames 21 and springs 24 in this embodiment are fixed into a whole through a plurality of connecting brackets at the bottom of the second steel frames 21. When installing or disassembling the device, the steps are relatively simple, and conventional straight steel columns are used, so that a larger space can be obtained at the bottom of the post-crushing transport mechanism 2, problems are easy to find during use, and the maintenance method is also clear, which helps to indirectly improve production efficiency.

[0037] Furthermore, if Figure 5 As shown, it also includes a head protection cover 3, which covers at least part of the top of the crusher and the top of the downstream of the pre-crushing transport mechanism 1 (the crusher and the pre-crushing transport mechanism 1 are not shown in the figure). Specifically, the shape of the head protection cover 3 is not limited, as long as it can meet the large-area coverage of the top of the crusher and the top of the downstream of the pre-crushing transport mechanism 1, and can effectively prevent the hazards caused by metal splashing, especially in extreme cases, accompanied by explosions, causing irregular movement of metal and causing personal injury to on-site workers, significantly improving the safety of the crusher during the transmission or processing of scrap metal. At the same time, the head protection cover 3 in this embodiment includes a plurality of square grids extending along the first direction and arranged in an equidistant array, which can help the ventilation and heat dissipation of the crusher while preventing the scrap metal from splashing out, ensuring that the machine will not overheat when working under high load, and the square grids can also reduce the noise when the machine is running.

[0038] Furthermore, if Figure 3As shown, the feeding belt 12 includes a machine chain plate 121, a machine sprocket 122 and a pin shaft 123. The machine chain plate 121 includes a pin barrel 1211 for being penetrated by the pin shaft 123, so that a plurality of machine chain plates 121 are connected in series along a first direction, and the machine sprocket 122 is fixedly arranged on both sides of the machine chain plate 121. Specifically, the feeding belt 12 in this embodiment forms a piano hinge ramp structure. Due to the close fit between the pin barrel 1211 of the machine chain plate 121 and the pin shaft 123, the feeding belt 12 can have a smaller gap, less waste metal leakage, and make the easily worn feeding belt 12 easier to maintain, and the machine chain plate 121 is easy to disassemble and replace.

[0039] At the same time, a guide plate 124 extending perpendicularly to the first direction is included between the machine sprocket 122 and the machine chain plate 121 to limit the scrap metal from detaching from the machine chain plate 121, and each machine chain plate 121 corresponds to a machine sprocket 122 and a guide plate 124. The multiple layers of guide plates 124 fit tightly together to form slightly raised metal walls extending along the first direction on both sides of the feeding belt 12, so that the scrap metal on the feeding belt 12 can be kept in the stable movement of the feeding belt 12.

[0040] like Figure 4 As shown, in another embodiment, it also includes a post-crushing transportation mechanism 2 arranged on one side of the magnetic separation drum 4. The magnetic separation drum 4 is arranged along the second direction and is used to perform secondary screening of the crushed scrap metal through different magnetic properties. The upstream and downstream of the post-crushing transportation mechanism 2 are closely matched with the magnetic separation drum 4 along the second direction, so as to carry out production efficiently and safely, and stably transmit the screened scrap metal on one side of the magnetic separation drum 4.
