[0005] The crushing assembly includes a first motor and two rotating rods. The two rotating rods are rotatably connected inside the housing. Crushing rollers are connected to the outside of each of the two rotating rods. The two crushing rollers mesh with each other. One end of one of the rotating rods is connected to the first motor. The cam is connected to the outside of one of the rotating rods.

[0006] The screening assembly includes a fixed frame, a discharge port connected to one side of the fixed frame, a screen connected inside the fixed frame, and the bottom of the cam overlapping the upper surface of the fixed frame.

[0007] The reset assembly includes a guide rod and a spring. The guide rod is connected in a slide groove and slidably connected in a fixed frame. The spring is sleeved on the outside of the guide rod, and the two ends of the spring are respectively connected to the slide groove and the movable frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, the vibrating fixed frame drives the screen to vibrate up and down, allowing the feed falling onto the screen to be quickly screened, thus improving the screening efficiency. When larger feeds slide through the storage port and trough into the conveying chamber, the second motor drives the spiral conveyor to transport the feed upwards in the conveying chamber. The feed then slides through the guide pipe onto two crushing rollers for crushing and falls back onto the screen for screening. This process allows the feed to be repeatedly processed and transformed into qualified feed, which then passes through the filter screen and moves to the bottom of the cavity, improving the screening quality of the feed.

[0017] This utility model, by providing a guide rod and a fixed frame, allows the guide rod to limit the movement of the fixed frame, enabling the fixed frame to reciprocate up and down along the axial direction of the guide rod under the action of the rotating cam and the spring force.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0026] Please see Figure 1-5 This utility model provides a screening device for livestock feed processing, including a screening shell 1, a crushing component 2, a screening component 3, four reset components 4, a conveying component 5, a guide pipe 6, and a cam 7. The screening shell 1 includes an outer shell 11, with four sliding grooves 12 inside the outer shell 11 and a through groove 14 on the other side of the outer shell 11. The outer shell 11 has a cavity 17 and a conveying cavity 15 inside. The guide pipe 6 is connected to the top of the outer shell 11. By setting the guide pipe 6, when the feed conveyed in the conveying cavity 15 falls into the guide pipe 6, the feed can move to the position between the two crushing rollers 23 through the inclined guide pipe 6.

[0027] The crushing assembly 2 includes a first motor 21 and two rotating rods 22. The two rotating rods 22 are rotatably connected inside the housing 11. Crushing rollers 23 are connected to the outside of each of the two rotating rods 22. The two crushing rollers 23 mesh with each other. One end of one of the rotating rods 22 is connected to the first motor 21. A cam 7 is connected to the outside of one of the rotating rods 22.

[0028] The screening component 3 includes a fixed frame 31, a discharge port 32 connected to one side of the fixed frame 31, and a screen 33 connected inside the fixed frame 31. By setting the screen 33, when the inclined screen 33 screens the feed, the unqualified feed can automatically slide into the discharge port 32.

[0029] The bottom of the cam 7 overlaps with the upper surface of the fixed frame 31. By setting the cam 7, since the bottom of the cam 7 overlaps with the fixed frame 31, the rotating cam 7 can push the fixed frame 31 to move downward.

[0030] The reset assembly 4 includes a guide rod 41 and a spring 42. The guide rod 41 is connected in the slide groove 12 and slidably connected in the fixed frame 31. The spring 42 is sleeved on the outside of the guide rod 41. The two ends of the spring 42 are respectively connected to the slide groove 12 and the movable frame. By providing the guide rod 41 and the fixed frame 31, the guide rod 41 can limit the movement of the fixed frame 31, so that the fixed frame 31 can reciprocate up and down along the axial direction of the guide rod 41 under the action of the rotating cam 7 and the elastic force of the spring 42.

[0031] The conveying assembly 5 includes a second motor 51, which is connected inside the housing 11. The output shaft of the second motor 51 is connected to a screw conveyor 52, which is rotatably connected inside the conveying chamber 15.

[0032] A baffle 13 is provided on one side of the outer shell 11, the through groove 14 is inclined, the top of the outer shell 11 is connected to the feed inlet 16, the bottom of the feed inlet 16 is located between two rotating rods 22, the cam 7 is located in the cavity 17, the bottom of the cavity 17 is inclined, the fixed frame 31 is located in four sliding grooves 12, the screen 33 is inclined, the discharge port 32 is located in the through groove 14, and the discharge port 32 is inclined. By setting the discharge port 32, because the discharge port 32 is inclined, when the feed on the surface of the screen 33 moves into the discharge port 32, the feed can pass through the inclined discharge port 32 and fall into the inclined through groove 14, and then slide into the conveying chamber 15 through the inclined through groove 14.

[0033] The fixed frame 31 is connected to the through groove 14 through the discharge port 32. The through groove 14 is connected to the conveying chamber 15. The conveying chamber 15 is connected to the cavity 17 through the guide pipe 6.

[0034] The working principle and usage process of this utility model are as follows: When the device needs to be used, feed is poured into the fixed frame 31 through the feed inlet 16. The first motor 21 is controlled to work. The working first motor 21 drives the crushing roller 23 and cam 7 to rotate through the rotating rod 22. Because the rotating crushing roller 23 meshes with the other crushing roller 23, and because the rotating crushing roller 23 drives the other crushing roller 23 to rotate, the upper parts of the two crushing rollers 23 move closer to each other. The rotating cam 7 pushes the fixed frame 31 to move downward. The downward moving fixed frame 31 slides downward outside the four guide rods 41. The downward moving fixed frame 31 compresses the spring 42. When the fixed frame 31 moves to the lowest position when the rotating cam 7 moves, the fixed frame 31 springs back to its lowest position. The fixed frame 31 moves upward under the action of the spring 42, causing the fixed frame 31 to vibrate up and down repeatedly under the action of the rotating cam 7 and the spring 42. The vibrating fixed frame 31 drives the screen 33 to vibrate up and down. The feed falling on the screen 33 can be quickly screened. The larger feed slides into the conveying chamber 15 through the storage port and the through trough 14. Then the working second motor 51 drives the spiral conveying rod 52 to convey the feed in the conveying chamber 15 upward. The feed conveyed upward slides onto the two crushing rollers 23 through the guide pipe 6. Then the two rotating crushing rollers 23 crush the feed. The crushed feed falls back onto the screen 33 for screening. The qualified feed passes through the filter screen and moves to the bottom of the cavity 17.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
