[0004] The above technical solution solves the problem of unsatisfactory sorting effect after crushing construction waste by the crushing and recycling device. However, the following shortcomings still exist. For example, when common waste crushing devices process discarded metal parts, due to the large differences in the shapes and sizes of metal parts, especially for larger metal parts, the cutting teeth are often difficult to crush effectively, which usually leads to equipment blockage or cutting tooth damage.

[0005] Therefore, the utility model provides a waste crushing and recycling device. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 , Figure 2 and Figure 5As shown, this embodiment provides a technical solution: a waste crushing and recycling device, including a crusher body 1, the inner cavity of the crusher body 1 is provided with a crushing assembly 2, the crushing assembly 2 includes a crushing shaft 21, the number of the crushing shafts 21 is two, and the two crushing shafts 21 are located on the side of the inner wall of the crusher body 1, the inner cavity of the crushing shaft 21 is provided with a plurality of mounting grooves 22, the bottom of the inner cavity of the mounting groove 22 is fixedly connected with a spring plate 23, the top of the spring plate 23 is provided with a connecting block 24, and the connecting block 24 is away from the side of the spring plate 23 A cutting tooth 25 is fixedly connected, and motors are respectively arranged on the sides of the two crushing shafts 21. The cutting teeth 25 on the surfaces of the two crushing shafts 21 mesh with each other. When the metal object is crushed, the cutting teeth 25 are in direct contact with the metal object, and the generated stress pushes the connecting block 24 and the cutting teeth 25 along the bottom of the inner cavity of the mounting groove 22. The cutting teeth 25 are in contact with the spring plate 23, and the spring plate 23 is compressed, thereby providing a reaction force. This force feedback helps to enhance the metal crushing effect. At the same time, the spring plate 23 also helps to disperse the impact force, thereby protecting the cutting teeth 25 from excessive wear or damage.

[0025] Furthermore, if Figure 1 , Figure 3 and Figure 4As shown: the inner cavity of the pulverizer body 1 is provided with a protective component 3, and the protective component 3 includes a mounting block 31, and the inner cavity of the mounting block 31 is provided with a connecting rod 32. A second slide groove 37 is provided on the side of the mounting block 31 away from the connecting rod 32, and a protective rod 33 is fixedly connected to the side of the connecting rod 32. One end of the protective rod 33 away from the connecting rod 32 penetrates and extends to the outside of the mounting block 31, and is slidably connected to the inner cavity of the second slide groove 37. The inner wall of the mounting block 31 is provided with a first slide groove 34, and the connecting rod 3 The two ends of the connecting rod 32 are fixedly connected with a first slider 35, the bottom of the connecting rod 32 is fixedly connected with a spring piece 36, the bottom of the crushing assembly 2 is provided with a collecting assembly 4, the collecting assembly 4 includes a supporting plate 41, the inner cavity of the supporting plate 41 is provided with a collecting box 42, the inner walls of the supporting plate 41 are provided with third slide grooves 44 on both sides, the two sides of the collecting box 42 are fixedly connected with a second slider 43, the end of the second slider 43 away from the collecting box 42 extends to the inner cavity of the third slide groove 44, and is slidably connected with the inner cavity of the third slide groove 44 A vibration motor is provided on the side of the connecting rod 32. By starting the vibration motor, the protective rod 33 can be driven to vibrate through the connecting rod 32. When the crushed object falls on the top of the protective rod 33, the crushed object can be sent back to the middle of the crushing assembly 2 through vibration, thereby achieving the effect of accelerating the crushing speed. At the same time, the connecting rod 32 can also prevent the crushed object from falling into the two sides of the crushing assembly 2, ensuring the concentration and safety of the crushing operation. By providing a spring piece 36, the connecting rod 32 can be buffered when it vibrates. By cooperating with the first slide groove 34 and the first slider 35, the movement trajectory of the connecting rod 32 can be limited when it vibrates, thereby preventing the connecting rod 32 from touching the crushing assembly 2. By providing a collection box 42, the crushed metal objects can be collected. A handle is provided on the side of the collection box 42. After the metal objects are crushed, the collection box 42 is taken out, thereby completing the recovery of the crushed objects. When the collection box 42 is taken out, the second slider 43 and the third slide groove 44 cooperate to limit its movement trajectory.

[0026] When crushing metal materials, a large amount of iron powder will be generated. When the crushed metal is collected, the iron powder will be collected together, which is very inconvenient for subsequent recycling.

A slot 52 is opened on the inner wall of the fixing plate 51. A magnet 53 is fixedly connected to the inner cavity of the slot 52. The crushed metal objects directly fall into the inner cavity of the collection box 42. By setting the magnet 53, the iron powder generated during the crushing can be adsorbed and collected, thereby achieving the effect of separating the crushed objects and the iron powder.

[0027] Working principle:

[0028] like Figure 1-5 As shown:

[0029] During use: first, the metal objects to be crushed and recovered are thrown in from the top of the pulverizer body 1. Some of the metal objects fall on the top of the protective rod 33. The vibration motor is started. The protective rod 33 shakes the metal objects on the top to the middle of the crushing component 2 through vibration. The motor is started, and the output shaft of the motor rotates forward, thereby driving the crushing shaft 21 to rotate. The spring plate 23 crushes the metal objects, and the crushed metal objects fall into the inner cavity of the collection box 42. The iron powder generated during the crushing is adsorbed and collected by the magnet 53. After the crushing is completed, the collection box 42 is taken out for recycling.
