[0002] With the development of the livestock industry, feed conversion efficiency and pen environment management have become key to improving breeding efficiency. By combining feed extrusion technology with enclosed pens, the aim is to improve feed utilization and optimize the pen environment. Feed extrusion, through high-temperature and high-pressure processing, makes the nutrients in the feed easier for pigs to absorb, while reducing manure emissions. Enclosed pens, through precise environmental control, such as temperature, humidity, and ventilation, provide pigs with a stable and comfortable growth environment. The combination of the two can not only significantly improve the growth rate and health level of pigs, but also effectively reduce the occurrence of diseases, lower breeding costs, and promote the development of the livestock industry towards a green, efficient, and sustainable direction.

[0025] 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 scope of protection of the present utility model.

[0026] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0027] This application discloses a feed extrusion and fermentation system. (Refer to...) Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 A feed extrusion and fermentation system includes a processing machine body 1. The processing machine body 1 includes a shell 101. A feeding hopper 108 is connected to the left side of the top of the shell 101. A servo motor 107 is fixedly connected to the left side of the shell 101. The output end of the servo motor 107 passes through the inner cavity of the shell 101 and is fixedly connected to a feeding rod 114. A compression rod 115 is fixedly connected to the right side of the feeding rod 114. A discharge rod 116 is fixedly connected to the right side of the compression rod 115. An outer frame 102 is fixedly connected to the right side of the shell 101. A discharge hopper 117 is connected to the bottom of the outer frame 102. A fermentation tank 127 is connected to the bottom of the discharge hopper 117. An anti-clogging mechanism 2 is installed on the surface of the discharge hopper 117.

[0028] The anti-clogging mechanism 2 includes a fixed sleeve 204, the inner cavity of which is fixedly connected to the surface of the discharge hopper 117. A base 212 is fixedly connected to the back side of the fixed sleeve 204. A rotating plate 207 is movably connected to the inner cavity of the base 212. A striking block 214 is fixedly connected to the bottom of the rotating plate 207. A convex rod 215 is movably connected to the top of the front side of the rotating plate 207.

[0029] Reference Figure 5 A rotating shaft 208 is fixedly connected to the inner cavity of the base 212. The surface of the rotating shaft 208 is movably connected to the top of the inner cavity of the rotating plate 207. A spring 213 is fixedly connected to the bottom of the front side of the rotating plate 207. The front side of the spring 213 is fixedly connected to the surface of the discharge hopper 117. Through the setting of the rotating shaft 208, the rotating plate 207 can rotate smoothly in the inner cavity of the base 212, thereby driving the striking block 214 to strike the surface of the discharge hopper 117. Through the setting of the spring 213, when the rotating plate 207 moves, the spring 213 will be stretched to absorb the energy of the generated force. Furthermore, when the rotating plate 207 returns to its original position, the spring 213 will restore its deformation, thereby achieving the effect of repeatedly striking the surface of the discharge hopper 117.

[0030] Reference Figure 3 and Figure 4 A servo motor 103 is installed on the right side of the outer frame 102. A rotating rod 120 is fixedly connected to the output end of the servo motor 103. The left side of the rotating rod 120 extends into the inner cavity of the outer frame 102 and is fixedly connected to a slice 119. An air inlet plate 113 is fixedly connected to the back side of the inner cavity of the outer frame 102. By starting the servo motor 103, the rotating rod 120 is driven to rotate. The rotation of the rotating rod 120 drives the slice 119 to rotate, thereby breaking up the clumps of feed. The air inlet plate 113 allows air to enter the inner cavity of the outer frame 102 and filters the air entering the outer frame 102.

[0031] Reference Figure 4 and Figure 5 A rotating column 205 is fixedly connected to the inner cavity of the convex rod 215. A roller 203 is fixedly connected to the right side of the rotating column 205. A pulley 202 is movably connected to the inner cavity of the roller 203. A roller 201 is fixedly connected to the top of the inner cavity of the pulley 202. The inner cavity of the roller 201 is fixedly connected to the surface of the slice 119. Through the roller 201, the pulley 202 and the roller 203, the rotating column 205 is rotated by the rotation of the rotating rod 120, thereby achieving the effect of rotating the rotating plate 207 by the rotation of the convex rod 215 and striking the surface of the discharge hopper 117.

[0032] Reference Figure 3 and Figure 4 Bearings 209 are fixedly connected to both sides of the surface of the rotating column 205. A fixing ring 211 is movably connected to the surface of the bearing 209. A support column 210 is fixedly connected to the top of the fixing ring 211. The top of the support column 210 is fixedly connected to the bottom of the outer frame 102. A limiting block 206 is fixedly connected to the left side of the rotating column 205. The limiting block 206 is circular. The rotation of the rotating column 205 drives the bearing 209 to rotate in the inner cavity of the fixing ring 211. This not only supports and stabilizes the rotating column 205 in the working state, but also reduces the wear between the rotating column 205 and the fixing ring 211 through the bearing 209. The setting of the limiting block 206 limits the rotating column 205 during the rotation process and prevents the rotating column 205 from falling out of the inner cavity of the fixing ring 211 during the rotation.

[0033] Reference Figure 3 and Figure 4 A support sleeve 121 is movably connected to the surface of the rotating rod 120. A connecting plate 118 is fixedly connected to the front and back sides of the top of the support sleeve 121. A support rod 122 is fixedly connected to the top of the connecting plate 118. The top of the support rod 122 is fixedly connected to the top of the inner cavity of the outer frame 102. A bracket 112 is fixedly connected to the right side of the servo motor 103. The left side of the bracket 112 is fixedly connected to the right side of the outer frame 102. The support sleeve 121, the connecting plate 118 and the support rod 122 are used to support the rotating rod 120 in the working state, so as to prevent the rotating rod 120 from falling off and shaking during rotation. The bracket 112 is used to support and stabilize the servo motor 103 in the working state, thereby ensuring the stability of the servo motor 103 during operation.

[0034] Reference Figure 1 , Figure 2 and Figure 6A connecting shell 106 is fixedly connected to the surface of fermentation tank 127. A servo motor 104 is fixedly connected to the top of fermentation tank 127. The output end of servo motor 104 extends through the inner cavity of fermentation tank 127 and is fixedly connected to a stirring rod 123. A feed pipe 105 is connected to the right side of the top of the inner cavity of fermentation tank 127. A discharge pipe 111 is connected to the bottom of both the inner cavity of fermentation tank 127 and the inner cavity of connecting shell 106. A pipe cover 110 is movably connected to the bottom of the surface of discharge pipe 111 and the top of the surface of pipe cover 110. By starting servo motor 104, the feed pipe 105 is connected to the inner cavity of fermentation tank 127. The operation of the servo motor 104 drives the stirring rod 123 to rotate. Through the feed pipe 105, the operator can smoothly pour the microbial catalyst into the inner cavity of the fermentation tank 127, thereby achieving the function of fermenting the feed. After fermentation, the feed is discharged through the discharge pipe 111. At the same time, the feed pipe 105 and the discharge pipe 111 are sealed by the pipe cover 110 in the working state, thereby preventing dust from entering the inner cavity of the fermentation tank 127 through the feed pipe 105 and the discharge pipe 111.

[0035] Reference Figure 6 and Figure 7 An annular tube 124 is fixedly connected to the inner cavity of the connecting shell 106. The top of the annular tube 124 is connected to a connecting tube 125, and the bottom of the annular tube 124 is connected to a connecting tube 126. The back sides of both connecting tubes 125 and 126 extend to the back side of the connecting shell 106. Sealing caps 109 are movably connected to the back sides of both connecting tubes 125 and 126. In special circumstances, when low-temperature or high-temperature fermentation is required, the operator can manually remove connecting tubes 126 and 125. Then, the operator pours cold or hot water into the inner cavity of connecting tube 126 and into the inner cavity of the annular tube 124. After being guided by the annular tube 124, the water enters the inner cavity of connecting tube 125, thereby achieving the effect of low-temperature and high-temperature treatment of the fermenter 127, thus ensuring the stability of the fermentation work inside the fermenter 127.

[0036] Working principle: First, servo motor 3 (107) is started. Servo motor 3 (107) drives the feeding rod 114 to rotate, which in turn drives the compression rod 115 to rotate. The compression rod 115 then drives the discharge rod 116 to rotate. Next, servo motor 1 (103) is started. Servo motor 1 (103) drives the rotating rod 120 to rotate within the support sleeve 121. The rotating rod 120 drives the slicer 119 to rotate. The operator manually pours the feed through the feed hopper 108 into the inner cavity of the outer shell 101, and the feed is conveyed by the feeding rod 114. The material is then conveyed to the compression rod 115, which propels the feed forward and gradually compacts it before it enters the compression and melting section. Subsequently, the distance between the tail end of the compression rod 115 and the outer casing 101 decreases, the pressure increases, and the feed is intensely stirred, mixed, and sheared. The raw material temperature rises and begins to melt. As the space further decreases, the feed is further heated and pressurized, resulting in cooking. The feed reaches a uniform stage. When the feed is instantly squeezed out from the discharge rod 116, the pressure is rapidly released, free water evaporates rapidly, and the feed expands. The water is quickly lost from the feed, thus solidifying and maintaining its expanded shape. The clumps of feed are dispersed by the slices 119. Next, when the rotating rod 120 rotates, it drives the roller 201 to rotate. When the roller 201 works, it causes the pulley 202 to work, which in turn drives the rollers. Roller 203 rotates, driving the rotating column 205 to rotate. The rotating column 205 then drives the convex rod 215 to rotate. When the convex rod 215 contacts the convex surface of the rotating plate 207, the rotating plate 207 rotates around the axis 208 to the rear, causing the striking block 214 to extend. The movement of the rotating plate 207 moves the striking block 214. When the convex rod 215 contacts the non-convex surface of the rotating plate 207, the rotating plate 207 rotates forward under the action of the spring 213, causing the striking block 214 to strike the surface of the discharge hopper 117. This strikes the discharge hopper 117, preventing blockage of the expanded feed inside. Simultaneously, the rotation of the rotating column 205 drives the bearing 209 to rotate within the inner cavity of the fixed ring 211. At the same time, the fixed ring 211 and the support column 210 support the rotating column 205 during operation. Finally, the servo motor 104 is activated, driving the stirring rod 123 to rotate. The material then enters the inner cavity of the fermentation tank 127 through the discharge hopper 117. The cap 110 on the surface of the feed pipe 105 is removed manually, and the microbial catalyst is poured into the inner cavity of the fermentation tank 127, thus achieving uniform mixing of the feed and the catalyst. The catalyst-completed feed is then discharged through the discharge pipe 111. Additionally, in special cases requiring low-temperature or high-temperature fermentation...The operator manually removes connecting pipes 126 and 125. Then, cold or hot water is poured into the inner cavity of connecting pipe 126, flowing into the inner cavity of the annular pipe 124. After being guided through the annular pipe 124, the water flows into the inner cavity of connecting pipe 125, thereby achieving the effect of low-temperature and high-temperature treatment of the fermenter 127, thus ensuring the stability of the fermentation process inside the fermenter 127.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
