[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 One embodiment provided by this utility model:

[0021] A vibrating screen for asphalt mixing equipment with quick-change screen includes: a shell 1, a front door 7, a vibration device 10, a C-shaped guide rail 12, a screen 13, and a hook 14. The outer side of the shell 1 is connected to a first observation port 2 by a hinge shaft. The screen body 9 is connected to the vibration device 10. The screen 13 is fixed inside the screen body 9 by a front tensioning device 15, the C-shaped guide rail 12, and the rear hook 14.

[0022] Furthermore, the outer side of the housing 1 is connected to the first observation port 2 and the second observation port 3 by a hinge. The top of the housing 1 is detachably connected to a cover plate. The handle 4 is bolted to one side of the second observation port 3. The upper end of the housing 1 is hollow to form a feed port 5.
