[0001] The utility model relates to the technical field of garbage disposal, and more specifically, to a metal crushing device after garbage incineration. Background Art
[0002] Waste incineration is a widely used waste disposal method. The metals contained in the waste residue after incineration can be processed and recycled. Before recycling, the scrap metal needs to be crushed into large pieces using a crushing device to facilitate subsequent recycling and processing.
[0003] The existing crushing device adopts a continuous feeding method, and directly enters the next process after one crushing. It is easy for large pieces of scrap metal to exist, resulting in poor crushing effect of the scrap metal and affecting subsequent processing procedures. Utility Model Content
[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a metal crushing device after waste incineration. During crushing, qualified smaller fragments can leak out from between the first sub-screening bars and cannot pass through the gap between the second sub-screening bars and the third sub-screening bars. After a period of crushing, the rotating shaft drives the first sub-screening bar and the second sub-screening bar to rotate, and the second sub-screening bar and the third sub-screening bar are staggered, so that larger fragments pass through and fall into the receiving box, thereby ensuring the crushing processing effect of the scrap metal.

[0006] The utility model is further configured as follows: a driving motor is arranged on the outer wall of the material receiving box, a reducer is arranged on the output shaft of the driving motor, and the output shaft of the reducer is transmission-connected to the rotating shaft through a pulley structure.
[0007] The utility model is further configured as follows: support rods are arranged on both inner walls of the crushing box, and the support rods are located below the first sub-screening rods and are used to support the first sub-screening rods.
[0008] The utility model is further configured as follows: a rubber sleeve is sleeved on the surface of the support rod.
[0009] The utility model is further configured as follows: guide plates are symmetrically arranged on the inner wall of the crushing box, and the two guide plates are located below the crushing roller and are inclined from top to bottom toward the two sides of the crushing box.
[0010] In summary, the utility model has the following beneficial effects:
[0011] During crushing, qualified smaller fragments can leak out from between the first sub-screen bars and cannot pass through the gap between the second sub-screen bars and the third sub-screen bars.

[0018] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0019] The utility model is described in detail below in conjunction with the accompanying drawings.
[0020] Reference Figure 1-Figure 3 , a metal crushing device after garbage incineration, comprising a frame 1 and a crushing box 2 fixed on the frame 1, two crushing rollers 3 are rotatably connected in the crushing box 2, a first discharge port 4 is provided at the bottom of the crushing box 2, a discharge port 5 is provided on the side wall of the crushing box 2, a receiving box 6 fixed on the frame 1 is connected at the discharge port 5, a second discharge port 7 is provided at the bottom of the receiving box 6, and a rotating shaft 8 is rotatably connected to the receiving box 6 at the discharge port 5, a plurality of uniformly arranged first sub-screen rods 9 and second sub-screen rods 10 are fixed on adjacent sides of the rotating shaft 8, the first sub-screen rod 9 extends into the crushing box 2 and is located below the crushing roller 3, a plurality of uniformly arranged third sub-screen rods 11 are fixed on the receiving box 6, the spacing between the plurality of first sub-screen rods 9 is smaller than the spacing between the second sub-screen rods 10 and the third sub-screen rods 11, and the third sub-screen rods 11 and the second sub-screen rods 10 are arranged at intervals, so that the gap formed between the third sub-screen rods 11 and the second sub-screen rods 10 is smaller than the spacing between the first sub-screen rods 9.
[0021] A driving motor 12 is fixedly provided on the outer wall of the receiving box 6, and a reducer 13 is fixedly provided on the output shaft of the driving motor 12. The output shaft of the reducer 13 is transmission-connected to the rotating shaft 8 via a pulley structure. The pulley structure is a mature prior art and will not be elaborated here.
[0022] Support rods 14 are fixedly provided on the inner walls on both sides of the crushing box 2. The support rods 14 are located below the first sub-screen rod 9 and are used to support the first sub-screen rod 9. During crushing, the support rods 14 support the first sub-screen rod 9 to prevent it from rotating, thereby reducing the load on the drive motor 12.
[0023] The surface of the support rod 14 is sleeved with a rubber sleeve 15 . When the fragments fall onto the first sub-screening rod 9 , the soft rubber material can provide a shock-absorbing effect for the first sub-screening rod 9 .
[0024] Guide plates 16 are symmetrically fixed on the inner wall of the crushing box 2. The two guide plates 16 are located below the crushing rollers 3 and are inclined from top to bottom toward the two sides of the crushing box 2. The fragments falling from between the two crushing rollers 3 can be diverted to both sides under the guidance of the guide plates 16 to avoid being overly concentrated in the middle of the first sub-screening rod 9, which would affect the sub-screening efficiency of the first sub-screening rod 9.
[0025] Working principle: When in use, scrap metal enters the crushing box 2, and the two crushing rollers 3 carry out crushing processing. The crushed fragments fall onto the first sub-screen rod 9, and qualified smaller fragments can leak from between the first sub-screen rods 9 and be discharged from the first discharge port 4, while larger fragments are retained in the first sub-screen rod 9. After crushing for a period of time, the scrap metal feeding is stopped, and the driving motor 12 slowly drives the rotating shaft 8 to rotate. During the rotation process, the second sub-screen rod 10 and the third sub-screen rod 11 are staggered, and the spacing between the second sub-screen rod 10 and the third sub-screen rod 11 is sufficient to allow larger fragments to pass through and fall into the receiving box 6 and be discharged from the second discharge port 7. In the crushing process, qualified fragments cannot pass through the gap between the second sub-screen rod 10 and the third sub-screen rod 11, thereby preventing these fragments from falling into the receiving box 6 together with unqualified fragments, causing unnecessary repeated crushing.
[0026] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
