[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example 1, referring to Figure 1-3A screening device for raw materials before crushing in mixed feed production includes a mounting frame 1, a support frame 10 mounted on top of the mounting frame 1, uprights 9 fixed on both sides of the upper end face of the support frame 10, rotating rods 14 rotatably mounted on opposite sides of the two uprights 9 via bearings, a screening screen plate 3 fixed between opposite ends of the two rotating rods 14, an L-shaped support plate 6 fixed to one end of the screening screen plate 3, a feeding hopper 5 fixed to one end of the horizontal section of the L-shaped support plate 6, a discharge structure for use with the feeding hopper 5 installed on the vertical section of the L-shaped support plate 6, an angle adjustment component installed between the bottom end of one side of the L-shaped support plate 6 and one end of the support frame 10, and an electromagnetic vibrator 12 installed on one side of the vertical section of the L-shaped support plate 6.

[0019] Disc springs 2 are fixed at the four corners of the upper end of the mounting frame 1, and the upper ends of the four disc springs 2 are fixed at the four corners of the lower end of the support frame 10.

[0020] The unloading structure includes an L-shaped insert plate 8 that is slidably inserted into the vertical section of the L-shaped support plate 6. A first electric push rod 7 is installed between the vertical section of the L-shaped insert plate 8 and the vertical section of the L-shaped support plate 6. The upper end of the horizontal section of the L-shaped insert plate 8 slides against the lower end face of the feeding hopper 5.

[0021] The angle adjustment assembly includes two U-shaped seats 13 fixed to the bottom of one side of the L-shaped support plate 6 and the top of the support frame 10, respectively, and a second electric push rod 11 is rotatably installed between the two U-shaped seats 13.

[0022] Both sides of the upper end face of the screening screen plate 3 are fixed with baffles 4 to prevent feed from splashing onto the outside of the screening screen plate 3 and causing waste.

[0023] The mounting frame 1 has two fixing holes 15 on one side. The mounting frame 1 is connected to the outer wall of the feed port of the crusher through the two fixing holes 15 by bolts, so that the screening screen plate 3 is placed above the feed port of the crusher.

[0024] Working principle: By controlling the extension and retraction of the second electric push rod 11, the screening screen plate 3 can be adjusted to an inclined state. The raw material to be screened is temporarily placed in the feeding hopper 5. By controlling the extension and retraction of the first electric push rod 7, the L-shaped insert plate 8 is moved, thereby adjusting the size of the bottom outlet of the feeding hopper 5, which facilitates the release of the raw material onto the screening screen plate 3. At the same time, controlling the size of the bottom outlet of the feeding hopper 5 facilitates the control of the unloading speed. By turning on the electromagnetic vibrator 12, the screening screen plate 3 is driven to vibrate. The vibration amplitude can be increased by using the disc spring 2 to elastically support the support frame 10. The screening screen plate 3 is used to screen the raw material. The qualified raw material rolls down the screening screen plate 3 into the feed port of the crusher. The screened impurities fall from the inside of the support frame 10 and the mounting frame 1 to the outside of the crusher. By controlling the extension and retraction of the second electric push rod 11, the screening screen plate 3 can be rotated to adjust the inclination of the screening screen plate 3, thereby adjusting the screening speed.

[0025] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
