[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0028] Depend on Figure 1 、 Figure 2 and Figure 3 As shown, a device for screening construction waste materials comprises a processing seat 1, an input port 2 and a screening component 3, wherein the screening components 3 are equidistantly arranged inside the processing seat 1, the input port 2 is fixedly installed on one side of the top opening of the processing seat 1, and a screening mechanism 4 for collecting metal materials in the waste is fixedly installed on one side of the inner wall of the processing seat 1, and an electromagnet 42 for generating magnetic force is provided in the screening mechanism 4, which utilizes the magnetic force emitted by the electromagnet 42 itself to adsorb the metal materials in the waste passing through the input port 2. During use, the construction waste to be screened is poured from the input port 2 to the upper surface of the screening component 3 through the use of the input port 2. In the process of the waste passing through the input port 2 and falling on the surface of the screening component 3, the electromagnet 42 will enter the operating state to adsorb the metal materials in the waste. Through the cooperation of other components in the device, the screening component 3 stably transports the construction waste, and screens the waste step by step according to the volume during the transportation process, so as to ensure the stability of the equipment when working.

[0029] By the attached Figure 3 As shown, in this embodiment, the screening mechanism 4 includes a mounting frame 41, an electromagnet 42 and a focusing slot 43. The mounting frame 41 is fixedly mounted on one side of the inner wall of the processing seat 1, and the electromagnet 42 is fixedly mounted inside the mounting frame 41. A focusing slot 43 is provided inside the processing seat 1 at the bottom end of the electromagnet 42. During use, through the use of the electromagnet 42 and the connection with the circuit, the electromagnet 42 itself will generate a certain magnetic force. By utilizing the property of metal materials and magnets to attract each other, the metal materials in the waste will be adsorbed on the surface of the electromagnet 42 under the action of the magnetic force. After the batch of waste has completely passed, the electromagnet 42 will disconnect its own power supply, the magnetic force of the electromagnet 42 itself disappears, and the waste adsorbed on the surface of the electromagnet 42 will fall into the focusing slot 43, which is convenient for the subsequent collection of the metal materials separately.

[0030] By the attached Figure 3As shown, in this embodiment, the screening mechanism 4 also includes a collecting bin 44, which is slidably installed inside the processing seat 1, and a sliding groove is provided in the processing seat 1 to cooperate with the sliding of the collecting bin 44. During use, the metal material falling into the collecting trough 43 is stably collected by using the collecting bin 44, which is convenient for the staff to process and collect the metal material separately.

[0031] By the attached Figure 4 As shown, in this embodiment, the construction waste material screening device also includes a vibration mechanism 5, which includes a rotating rod 51, a raised wheel 52 and a driving assembly 53. The rotating rod 51 is symmetrically rotatably installed on the inner wall of the processing seat 1, the raised wheel 52 is symmetrically fixedly installed on the outside of the rotating rod 51, and the driving assembly 53 is fixedly installed on the side of the processing seat 1. During use, the rotating rod 51 rotates stably inside the processing seat 1 through the start-up and operation of the driving assembly 53. During the rotation process, the raised wheel 52 uses its own structure and shape to adjust the position of the screening assembly 3. When the raised end of the raised wheel 52 contacts the bottom end of the screening assembly 3, the overall position of the screening assembly 3 moves upward. As the raised wheel 52 continues to rotate, the smooth surface of the raised wheel 52 contacts the bottom end of the screening assembly 3. At this time, the overall position of the screening assembly 3 moves downward, and the reciprocating up and down shaking of the screening assembly 3 is used to screen the construction waste existing on the surface of the screening assembly 3.

[0032] By the attached Figure 5 As shown, in this embodiment, the driving assembly 53 includes a linkage wheel 531, a conveyor belt 532, an outer shell 533 and a driving motor 534. The outer shell 533 is fixedly mounted on the side of the processing seat 1, and the rotating rod 51 passes through the inner wall of the processing seat 1 and enters the outer shell 533. The linkage wheel 531 is fixedly mounted on the outside of the rotating rod 51, and the conveyor belt 532 is slidably mounted between the linkage wheels 531. The driving motor 534 is fixedly mounted on the side of the outer shell 533. The output end of the driving motor 534 is fixedly connected to the end of one group of rotating rods 51. When the driving motor 534 is started during use, the output end of the driving motor 534 drives one group of rotating rods 51 to rotate. At this time, the linkage wheel 531 outside the group of rotating rods 51 rotates synchronously with the rotating rods 51. Then, with the cooperation of the conveyor belt 532, the two groups of rotating rods 51 enter a state of synchronous rotation. When in use, there is a certain height difference between the heights of the two groups of rotating rods 51, allowing the screening assembly 3 to screen construction waste in an inclined posture.

[0033] By the attached Figure 6As shown, in this embodiment, the screening assembly 3 includes a screening mesh 31 and a limiting rod 32. The screening mesh 31 is slidably installed inside the processing seat 1, and the limiting rod 32 is symmetrically fixed on both sides of the screening mesh 31. The inner wall of the processing seat 1 is symmetrically provided with lifting grooves, and the limiting rod 32 is slidably connected to the lifting grooves. During use, the limiting rod 32 is used to allow the screening mesh 31 to slide up and down along the lifting grooves inside the processing seat 1 under the action of the limiting rod 32, so that the screening mesh 31 as a whole moves in a vertical lifting posture, thereby ensuring the stability of the overall component during the shaking of the screening mesh 31.

[0034] By the attached Figure 6 As shown, in this embodiment, the screening assembly 3 also includes a guide plate 33, which is fixedly installed at the side opening of the processing seat 1 at equal intervals. During use, multiple groups of guide plates 33 are installed and used. The guide plates 33 can direct the discharge of materials screened out by the corresponding screening net 31, making it convenient for staff to collect materials of different specifications separately.

It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the concept of the present invention, which should be regarded as falling within the scope of protection determined by the claims submitted for the present invention.
