Description

Technical Field

[0001] This utility model relates to the technical field of mixed feed production equipment, specifically to a mixed feed pelleting device. Background Technology

[0002] Mixed feeds are mostly made from energy sources such as corn, wheat, and barley to provide carbohydrates, protein sources such as soybean meal, fish meal, and rapeseed meal to supplement amino acids, crude fiber such as wheat bran and alfalfa meal to promote digestion, and other minerals and vitamins. Currently, most pelleting is done using extruders. Because the mixture of feeds is relatively loose, the material flow within the extruder hopper is often not smooth, affecting the continuity of pelleting at the extruder head. The extruded material needs to be cut, and existing cutting processes are mostly driven by independent power sources, resulting in complex structures. Since the feed pelleting process requires heating to gelatinize starch and soften the material, the temperature of the pelleted feed can typically reach around 70-80℃. The direct release of heat into the factory increases the indoor temperature, and odors from the heating process also affect the working environment. Utility Model Content

[0004] This utility model includes an extrusion base, an extrusion cylinder, an extrusion head, a dispersing roller, and an extrusion motor. The extrusion cylinder is fixed to the extrusion base, and the extrusion base is provided with a heating component for heating the extrusion cylinder. The extrusion cylinder is provided with an extrusion assembly, and the top of the extrusion cylinder is provided with a feed hopper. The dispersing roller is rotatably installed in the feed hopper.

[0006] The extrusion assembly includes an extrusion shaft and a spiral extrusion blade. The spiral extrusion blade is fixed to the extrusion shaft. The extrusion head is provided with an extrusion shaft mounting hole. One end of the extrusion shaft passes through the extrusion shaft mounting hole and extends to the outside of the extrusion head. The cutting blade is mounted on the extrusion shaft and fits against the outside of the extrusion head.

[0007] The dispersing roller has a ring array of multiple sets of dispersing teeth, and the dispersing roller is connected to the extrusion shaft by a belt or gear.

[0016] As shown in the attached drawings, this utility model includes an extrusion base 23, an extrusion cylinder 24, an extrusion head 25, a dispersing roller 26, and an extrusion motor 27. The extrusion cylinder 24 is fixedly connected to the extrusion base 23. The extrusion base 23 is provided with a heating component 30 for heating the extrusion cylinder 24. An extrusion component 31 is provided inside the extrusion cylinder 24. A feed hopper 32 is provided at the top of the extrusion cylinder 24. The dispersing roller 26 is rotatably installed in the feed hopper 32. The extrusion motor 27 is installed on the extrusion base 23 and drives the extrusion component 31 and the dispersing roller 26 to rotate. The extrusion head 25 is installed at the front end of the extrusion cylinder 24. A cutting blade 33 is provided on the extrusion component 31 extending to the outside of the extrusion head 25. A heat collection and guiding cylinder 34 is provided on the extrusion base 23 and sleeved on the extrusion head 25.

[0017] The mixed material is fed into the feed hopper 32. The heating component 30 is used to heat the material in the extrusion cylinder 24 at a temperature of 100-120℃. The starch gelatinizes when heated, making the material soft. Then, the extrusion component 31 extrudes the material from the extrusion head 25 in strip form. The cutting blade 33 cuts the extrudate into granules during rotation. The dispersing roller 26 rotates in the feed hopper 32 to disperse the material and make it fall evenly into the extrusion cylinder 24, ensuring the continuity of extrusion.

[0018] After the material is extruded and cut from the extruder head 25, the temperature can reach 70-80℃. The heat collection and guide tube 34 is used to collect the heat emitted by the granular material and carry the heat out to the outside, thus optimizing the indoor environment.

[0019] Preferably, the heating assembly 30 includes a heating cylinder mounted on the extrusion cylinder 24, and a set of electric heating wires are provided inside the heating cylinder.

[0020] Preferably, the extrusion assembly 31 includes an extrusion shaft 36 and a spiral extrusion blade 37. The spiral extrusion blade 37 is fixed to the extrusion shaft 36. The extrusion head 25 is provided with an extrusion shaft mounting hole. One end of the extrusion shaft 36 passes through the extrusion shaft mounting hole and extends to the outside of the extrusion head 25. The cutting blade 33 is mounted on the extrusion shaft 36 and fits against the outside of the extrusion head 25.

[0021] The cutting blade 33 includes a blade holder and a set of blades mounted in a ring on the blade holder. The cutting blade 33 is detachably mounted on the extrusion shaft 36 and rotates synchronously with the extrusion shaft 36. The number of blades can control the particle size of the granules. The more blades there are, the smaller the cutting distance between the front and rear blades, the faster the cutting frequency, and the smaller the granules. Conversely, the smaller the granules, the larger the granules. Different numbers of blades can be installed according to the required particle size.

[0022] Furthermore, the dispersing roller 26 has multiple sets of dispersing toothed rods arranged in a ring, and the dispersing roller 26 is connected to the extrusion shaft 36 by a belt or gear. The dispersing roller 26 and the extrusion shaft 36, which extend out of the feed hopper 32 and the extrusion cylinder 24, are respectively provided with matching pulleys or transmission gears, and the dispersing roller 26 is connected to the extrusion shaft 36 by a belt or gear.

[0023] Furthermore, the heat collection guide tube 34 is installed at an angle on the extrusion base 23. A cover plate 38 is provided at the discharge end of the heat collection guide tube 34, with a discharge port at the bottom of the cover plate 38 and an exhaust pipe on the cover plate 38. The heat collection guide tube 34 is composed of two semi-cylinders hinged together, one half of which is movable and can be opened, facilitating the replacement and maintenance of the inner extrusion head 25. The exhaust pipe extends outside the plant, creating a chimney effect to quickly remove the hot air from inside the heat collection guide tube 34.
