Description

Technical Field

[0001] The utility model belongs to the technical field of feed production, and particularly relates to a pellet feed extrusion device. Background Art

[0002] Most feeds are in the shape of pellets. Therefore, in the production and processing, it is necessary to process the materials into pellets. An extrusion structure is used to extrude and discharge the materials, and then a cutting structure is used to cut the extruded materials to form a pellet state. The feed pelletizer, also known as the granular feed pelletizer, is a feed processing machine that directly presses the pulverized materials such as corn, soybean meal, straw, grass, and rice husk into pellets. The feed pelletizer is widely applicable to large, medium, and small aquaculture farms, grain feed processing plants, livestock farms, poultry farms, individual farmers, and small and medium-sized farms, as well as farmers or large, medium, and small feed processing plants; the feed pelletizer is divided into a ring die feed pelletizer, a flat die feed pelletizer, and a pair-roll feed pelletizer.

[0003] The Chinese patent with the comparative announcement number CN205358161U discloses a pellet feed extrusion device, which includes an extrusion barrel, an annular knife rest, and a pellet hopper. The characteristics are that the bottom of the pellet hopper is provided with supporting feet, the extrusion barrel is welded inside the pellet hopper, a driving motor and a feed pipe are arranged at the top of the extrusion barrel, the lower end of the driving motor is connected with a rotating shaft, a spiral blade is welded on the rotating shaft, a plurality of discharge holes are uniformly arranged on the side wall of the extrusion barrel, an annular knife rest is sleeved outside the extrusion barrel, scrapers are installed on both sides of the annular knife rest, and the annular knife rest is installed on a telescopic arm.

The pellet feed freely falls onto the discharge hopper 105 supported by the support rods 104 and is discharged;

[0029] In this embodiment: The power mechanism includes a DC motor 201. A rotating shaft 202 is installed at the output end of the DC motor 201. A plurality of stirring blades 203 are evenly arranged on the upper section of the rotating shaft 202. A spiral blade 204 is arranged on the lower section of the rotating shaft 202.

The wire knives 207 are respectively tangent to all the extrusion holes 306. The annular tool holder 206 is bolted to the installation seat 205. The installation seat 205 is bolted to the rotating shaft 202. When the DC motor 201 rotates in reverse, the stirring blades 203 are driven by the rotating shaft 202 to stir the feed. When the DC motor 201 rotates forward, the spiral blade 204 is driven to rotate forward, pushing the feed raw materials into the extrusion cylinder 304. The rotating shaft 202 drives the annular tool holder 206 to rotate through the installation seat 205. The annular tool holder 206 drives the wire knives 207 to cut the extruded feed into particles;

[0030] In this embodiment: The holding mechanism includes a stirring tank 301. A feed hopper 302 is arranged on one side of the stirring tank 301. A water inlet pipe 303 is arranged at the top of the stirring tank 301. An extrusion cylinder 304 is arranged at the bottom of the stirring tank 301.

[0031] Working principle: The support frame 101 fixedly supports the stirring tank 301 through the first fixing ring 102.

When the DC motor 201 rotates in reverse, the stirring blades 203 are driven by the rotating shaft 202 to stir the feed. At this time, the spiral blade 204 rotates in reverse to prevent the feed raw materials from entering the extrusion cylinder 304. During the stirring process, water can be injected into the stirring tank 301 through the water inlet pipe 303. After the stirring is completed, the DC motor 201 rotates forward, driving the spiral blade 204 to rotate forward, pushing the feed raw materials into the extrusion cylinder 304 supported and fixed by the second fixing ring 103, and extruding them through the extrusion holes 306 on the discharge plate 305. At the same time, the rotating shaft 202 drives the annular tool holder 206 to rotate through the installation seat 205. The annular tool holder 206 drives the wire knives 207 to cut the extruded feed into particles. The granular feed freely falls onto the discharge hopper 105 supported by the support rod 104 and is discharged.
