DETAILED DESCRIPTION

[0026] 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.

[0027] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0028] Embodiment 1:

[0029] A production device for preparing recycled building materials from construction waste comprises a support leg 1, the top of the support leg 1 is connected to a crushing structure, the bottom of the crushing structure is connected to a screening structure, and the bottom of the screening structure is provided with a discharging structure.

[0030] The crushing structure includes a crushing unit and a protection unit. The protection unit includes a rotating shaft 104. Torsion springs 105 are installed at one end of the front and back of the outer surface of the rotating shaft 104. Limiting blocks 106 are installed at both ends of the rotating shaft 104. A protection plate 107 is installed in the middle of the outer surface of the rotating shaft 104. The crushing unit includes a workbench 101. A crusher 102 is installed in the middle of the top surface of the workbench 101. A feed hopper 103 is installed on the top of the crusher 102.

[0032] By setting up the crushing structure and utilizing the torsion force of the torsion spring 105, when the material is placed on the top surface of the protective plate 107, gravity squeezes the protective plate 107 to rotate and causes the material to fall into the feed hopper 103 and the crusher 102. After the material enters, the rebound force of the torsion spring 105 is utilized to restore the protective plate 107 for protection, thereby preventing damage caused by splashing of crushed materials.

[0033] When the material is crushed, the material is placed on the top of the protective plate 107. Due to gravity, the protective plate 107 and the rotating shaft 104 are pressed to rotate, and the torsion spring 105 is twisted at the same time, so that the material falls into the feed hopper 103 and the crusher 102 to be crushed. After the material enters the crusher 102, the restoring deformation force of the torsion spring 105 is used to drive the rotating shaft 104 to rotate, so that the protective plate 107 returns to its initial state, forming a seal on the top of the feed hopper 103, thereby effectively preventing the material from splashing when the crusher 102 crushes the material.

[0034] Embodiment 2:

Since the toggle shaft 204 is provided with a protrusion on its surface, when the toggle shaft 204 surface is connected with the toggle plate 205 surface in rotation, the toggle plate 205 will move up and down, thereby driving the left end of the screening plate 206 to move.
