[0038] like Figures 1 to 6As shown, this application proposes a feed screening device for feed processing, including a main component 100. The main component 100 includes a housing 101, an inlet pipe 102, and an outlet pipe 103. The inlet pipe 102 is located at the top of the housing 101, and feed enters the housing 101 through the inlet pipe 102. The outlet pipes 103 are located on both sides of the housing 101, and feed entering the housing 101 is discharged from different outlet pipes 103 according to the size of the feed particles. The device also includes a screening component 200. The screening component 200 includes a screening plate 204, a connecting rod 205, a screening motor 206, a cable 207, a push cylinder 209, a spring 210, a push plate 212, and a storage cavity 213. The end of the screening plate 204 is rotatably connected to the housing. Inside the body 101, there are three screening plates 204, which are inclinedly arranged inside the body 101. A connecting rod 205 is slidably connected inside the body 101, with its bottom fixed to the end of the uppermost screening plate 204. When the connecting rod 205 slides up and down inside the body 101, it can cause the screening plate 204 to swing slightly inside the body 101. A screening motor 206 is fixed to the top of the body 101, and the upper end of the connecting rod 205 extends outside the body 101. Multiple springs 210 are fixed between the connecting rod 205 and the body 101, with the springs 210 located on the upper side of the body 101. A cam is fixed to the end of the rotating shaft of the screening motor 206, and the cam contacts the connecting rod 205, driving the screening motor 206. The cam rotates, pushing the connecting rod 205 to slide up and down inside the housing 101. A cable 207, an elastic rubber band, is fixed between the screening plates 204. The cable 207 is in contact with the inner wall of the housing 101. When the connecting rod 205 causes the uppermost screening plate 204 to swing, the cable 207 causes the remaining screening plates 204 to swing as well. The screening plates 204 have perforations, with the diameter decreasing from top to bottom. The middle screening plate 204 is connected to the outside of the housing 101 via a discharge pipe 103, through which larger feed particles are discharged. The lower screening plate 204 is connected to the outside of the housing 101 via another discharge pipe 103, through which smaller feed particles are discharged. Feed is discharged through pipe 103 and graded according to feed particle size. Storage chamber 213 is located inside box 101 and below screening plate 204. When screening feed, powder in feed passes through the holes on screening plate 204 and falls into storage chamber 213. Push plate 212 is slidably connected inside storage chamber 213 and fits against the side wall of storage chamber 213. Push cylinder 209 is located outside box 101 and push plate 212 is fixed to the piston rod end of push cylinder 209. Push cylinder 209 drives push plate 212 to slide inside storage chamber 213. Push plate 212 compresses the feed powder falling into storage chamber 213 into blocks. The compressed feed blocks can be reprocessed into granular feed.

[0039] Preferably, a connecting belt 214 is fixed to the end of the screening plate 204 located inside the discharge pipe 103, and the other end of the connecting belt 214 is fixed to the inner wall of the box 101. The connecting belt 214 is an elastic rubber plate. When the screening plate 204 swings, it can pull the connecting belt 214, and the feed particles on the inclined screening plate 204 enter the discharge pipe 103 from the connecting belt 214.

[0040] Preferably, the screening component 200 further includes a nozzle 201, a water tank 202, a water pump 203, and a water pipe 215. The water tank 202 is fixed to one side of the housing 101, the water pump 203 is located inside the water tank 202, and the water pipe 215 is fixed inside the storage cavity 213. Multiple nozzles 201 are fixed on the water pipe 215, and the outlet of the nozzle 201 faces the bottom of the storage cavity 213. The water in the water tank 202 is driven by the water pump 203 to spray water from the nozzle 201 to form a water mist. The water mist can moisten the feed particles in the storage cavity 213, making it easier for the pusher plate 212 to compress the feed powder into a shaped cake.

[0041] Preferably, a water inlet pipe 215 is fixed on the water storage tank 202, and water is replenished into the water storage tank 202 through the water inlet pipe 215 to keep the water storage tank 202 with sufficient water.

[0042] Preferably, a rectangular opening is provided on the side wall of the box 101 near the bottom, which connects the storage cavity 213 to the outside. A door panel 208 is rotatably connected to the rectangular opening. The door panel 208 is closed when screening feed. When a certain amount of feed powder is stored in the storage cavity 213, the feed powder is compressed into shape by the push plate 212, and the shaped feed powder is taken out by opening the door panel 208.

[0043] Preferably, the discharge pipe 103 has hooks on both sides, and the feed belt is hung at the outlet of the discharge pipe 103 by the hooks, so that the feed discharged from the discharge pipe 103 is loaded into the feed belt.

[0044] Preferably, the connecting rod 205 is an inverted U-shaped rod. The cam at the end of the shaft of the screening motor 206 contacts the top of the connecting rod 205. One end of the spring 210 is fixed to the other side of the top of the connecting rod 205 that contacts the cam, and the other end is fixed to the top of the housing 101. When the cam rotates, it pushes the connecting rod 205 to slide downwards, and the spring 210 can push the connecting rod 205 to slide upwards. The cam is elliptical. Under the combined action of the cam and the spring 210, the connecting rod 205 swings continuously with small amplitude within the housing 101.

[0045] Preferably, the water storage tank 202 is equipped with two water pumps 203, and the storage cavity 213 is fixed with two water pipes 215. The water pipes 215 are respectively fixed to the outlet of the water pumps 203 and fixed to the opposite side walls of the storage cavity 213. The water pumps 203 deliver water to the water pipes 215 on both sides of the storage cavity 213 and spray it out through the nozzles 201.

[0046] Preferably, the water mist particles sprayed by the nozzle 201 have a diameter of 5μm to 8μm, which can wet the feed dust while avoiding excessive wetting of the feed and affecting its quality.

[0047] Preferably, the two ends of the cable 207 are rotatably connected to the rotating seat 211, which is fixed on the upper and lower sides of the screening plate 204. The end of the connecting rod 205 is rotatably connected to the rotating seat 211. The rotating seat 211 is located on both sides of the screening plate 204 and fits against the inner side wall of the box 101. When the connecting rod 205 drives the screening plate 204 to swing up and down, the rotating seat 211 causes the connecting rod 205 and the screening plate 204 to rotate relative to each other. When the cable 207 pulls the screening plate 204 to rotate, the rotating seat 211 causes the cable 207 and the screening plate 204 to rotate relative to each other.

[0048] In practical use, a feed screening device for feed processing according to an embodiment of this application is as follows:

[0049] After the feed is poured into the housing 101 through the feed pipe 102, the screening motor 206 drives the cam to rotate. During the rotation of the cam, the connecting rod 205 is pressed down, causing the connecting rod 205 to slide downwards within the housing 101. The spring 210 located on the lower side of the connecting rod 205 can push the connecting rod 205 upwards, causing it to slide upwards. Through the combined action of the cam and the spring 210, the connecting rod 205 slides up and down repeatedly. During the sliding process, the connecting rod 205 causes the uppermost screening plate 204 to swing slightly within the housing 101. During the swinging process, the screening plate 204 will drive the other two screening plates 204 to swing along via the cable 207. The feed particles roll from the uppermost screening plate 204 to the middle screening plate 204, causing the feed powder attached to the feed particles to fall off. During the oscillation of the screening plate 204, large feed particles slide down the inclined screening plate 204 into the discharge pipe 103. Small feed particles pass through the holes of the middle screening plate 204 and fall onto the lower screening plate 204. The small feed particles roll on the lower screening plate 204 and flow out from the discharge pipe 103. During the oscillation of the lower screening plate 204, the powder mixed in the feed passes through the holes of the screening plate 204 and falls into the storage chamber 213 at the bottom. Driven by the water pump 203, water mist is sprayed into the storage chamber 213 through the nozzle 201 to moisten the feed powder. Driven by the push cylinder 209, the push plate 212 compresses the moistened feed powder into blocks. Then, the compressed feed powder blocks are periodically removed and used to reprocess into feed pellets.

[0050] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, various modifications and variations are possible with this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
