[0002] The existing models are mainly horizontal structures, consisting of drive components, housing components, main shaft assembly, fixed blades, moving blades, screen components, pushing device, frame, etc. The shredding chamber of the existing metal scrap shredder is too small. When a large amount of material is put in, bridging will occur and the material will not be able to be fed out. An auxiliary pushing device is required to shred smoothly. Large foreign objects entering the shredder can easily cause jamming and damage to the blades.

[0003] Large foreign objects are unavoidable in metal shavings and cannot be accurately removed before processing. Existing shredders cannot remove these large foreign objects, and damage to the shredder blades is unavoidable. Furthermore, liquid materials cannot be effectively collected during processing, requiring a separate liquid collection device. Therefore, a vertical metal shavings crusher needs to be designed to solve these problems.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through the specific circumstances.

[0029] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] See Figure 1 and Figure 2 This utility model provides a vertical metal scrap crusher, comprising:

[0031] Frame 1, on which a crushing mechanism is installed;

[0032] The crushing mechanism includes a motor 2, a reducer 3, a main shaft 4, a lower housing 6, a feeding disc 7, a fixed disc cutter 8, a moving disc cutter 9, a moving cone cutter 10, a liner plate 11, a feed hopper 12, an upper housing 13, and a discharge assembly;

[0033] Both motor 2 and reducer 3 are fixedly installed inside the frame 1. The output end of motor 2 is fixedly connected to reducer 3. The main shaft 4 is installed on reducer 3. It should be noted that by starting motor 2, the main shaft 4 can be rotated.

[0034] The feeding disc 7, the fixed disc knife 8, the moving disc knife 9, and the moving conical knife 10 are all fixedly installed on the main shaft 4. The lower housing 6 is fixedly installed on the frame 1. The upper housing 13 is fixedly installed on the lower housing 6. The inner liner 11 is installed inside the upper housing 13. The feed hopper 12 is installed on the top of the upper housing 13.

[0035] Through the aforementioned crushing mechanism, motor 2 drives reducer 3, which in turn drives main shaft 4 to rotate. The structure is larger at the top and smaller at the bottom. The upper part of the feed hopper 12 is square, while the lower part is an octagon. The feed opening size is maximized. The upper box 13 is designed with an octagonal structure both top and bottom. The manufacturing process is simple. The disc fixed knife 8, disc moving knife 9, and conical moving knife 10 are evenly distributed on the main shaft 4. The conical moving knife 10 rotates clockwise to bring the material into the upper box 13. The conical moving knife 10 and the inner lining plate 11 of the upper box 13 crush the material. After crushing, the material falls into the lower box 6. The disc moving knife 9 and the disc fixed knife 8 in the lower box 6 perform secondary shearing on the material. The material after secondary crushing is pushed to the discharge port 16 by the rotating feed plate 7. The material after secondary shearing can meet the discharge requirements. When encountering material containing large pieces of foreign matter.

[0036] The inner lining plate 11 of the box is made of cast manganese steel in one-time casting process, which has good wear resistance and low maintenance cost. The inner side of the inner lining plate 11 is designed with a spiral convex cutting edge. The spiral convex cutting edge is designed with the opposite rotation direction to the conical moving knife 10. After crushing, the material can automatically enter the lower box 6. The circumferential saw tooth spacing of the disc moving knife 9 determines the size of the material after secondary shearing. If the material is smaller than the saw tooth spacing of the disc moving knife 9, the material will leak out from the bottom and be pushed to the discharge port 16 by the lower feeding plate 7.

[0037] This machine's structure allows for zero leakage when processing materials containing liquids; the liquid is discharged along with the material, facilitating solid-liquid separation in subsequent processes.

[0038] Specifically, the discharge assembly includes a hydraulic cylinder 14, a discharge gate 15, and a discharge port 16. The hydraulic cylinder 14 is installed on the upper housing 13, and the output end of the hydraulic cylinder 14 is fixedly connected to the discharge gate 15. The discharge port 16 is installed on the frame 1 and the lower housing 6.

[0039] With the aforementioned discharge assembly, this machine can discharge large foreign objects together with the crushed and sheared materials. It can effectively hook the materials in the feed hopper 12 into the lower box 6 for crushing. This machine does not require an auxiliary pushing device, and there will be no bridging of materials, thus reducing the equipment manufacturing cost.

[0040] When the material contains large foreign objects, and the current value of the main shaft 4 exceeds the normal current value for crushing materials during rotation, the hydraulic cylinder 14 in the discharge assembly opens the discharge gate 15. The hydraulic cylinder 14 is opened by the hydraulic station. The motor 2 switches between forward and reverse rotation to drive the conical moving blade 10 on the main shaft 4 to carry the foreign objects to the discharge gate 15 and discharge them together with the material. The discharge assembly solves the problem of machine jamming and manual picking after foreign objects enter the equipment, eliminating the need for long-term downtime, reducing and shortening maintenance time, and improving production efficiency.

[0041] Specifically, a bearing seat 5 is fixedly installed inside the frame 1, and the spindle 4 is installed on the bearing seat 5. The top end of the spindle 4 passes through the lower housing 6 and extends into the upper housing 13. It should be noted that this is to facilitate the stable rotation of the spindle 4.

[0042] Specifically, the rack 1 has multiple heat dissipation holes and an inspection door, which facilitates the inspection and maintenance of the inside of the rack 1.

[0043] Specifically, a discharge channel is provided on the upper box 13, and a discharge door is used to block the discharge channel. It should be noted that this is to facilitate the blocking of the discharge channel.

[0044] Specifically, the inner side of the inner liner 11 of the box is provided with a spiral convex cutting edge, which rotates in the opposite direction to the conical moving knife 10. The disc moving knife 9 is provided with circumferential serrations. It should be noted that the spiral convex cutting edge design on the inner side of the inner liner 11 of the box, with the spiral convex cutting edge rotating in the opposite direction to the conical moving knife 10, allows the crushed material to automatically enter the lower box 6. The spacing of the circumferential serrations of the disc moving knife 9 determines the size of the material after secondary shearing. If the material is smaller than the spacing of the serrations of the disc moving knife 9, it will leak out from below and be pushed to the discharge port 16 by the lower feeding plate 7.

[0045] The above provides a detailed description of a vertical metal scrap crusher provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
