Description

Technical Field

[0001] This invention relates to the field of feed production equipment technology, and in particular to an extrusion device for producing feed additives. Background Technology

[0002] An extrusion unit for feed additive production is a specialized piece of equipment used in the feed production process, primarily for extruding pig feed. This device typically combines high pressure and mechanical force, using a screw or other type of extrusion method to mix feed ingredients with additives, creating a homogeneous mixture. This extrusion process enhances the nutritional value, palatability, and digestibility of the feed, thereby promoting animal health and improving production efficiency.

[0003] However, existing extrusion devices have certain problems when processing frozen feed. Typically, frozen feed needs to be mixed with additives during extrusion to ensure uniformity. However, even after mixing, granular feed may still remain, affecting subsequent extrusion results. Because granular feed cannot be processed sufficiently uniformly, it may lead to uneven additive distribution or instability during processing, thus affecting the final feed quality and the pigs' intake.

[0004] Chinese Patent Publication No. CN112193774B discloses an extrusion device for producing feed additives, including a frame, a support frame, a fixed plate, a workstation, a feed pipe, an extrusion mechanism, a cleaning component, a rotating component, a discharge mechanism, and a collection mechanism. The cleaning component includes a washing mechanism and a drying mechanism. The washing mechanism, drying mechanism, extrusion mechanism, and feed pipe are equidistantly distributed in a circular pattern around the axis of the workstation. The beneficial effects of the above patent document are that the workstation has four extrusion through holes, which are sequentially connected to the feed pipe, extrusion mechanism, washing mechanism, and drying mechanism, which can effectively improve production efficiency; the workstation is further limited by the adsorption of an electromagnet ring and a magnetic metal ring; the feed additive in the extrusion through holes can be effectively prevented from clogging; the extrusion through holes can be cleaned during one production process; and the feed additive in the extrusion through holes can be collected for reuse, reducing cost input.

[0005] While the patent literature mentioned above can achieve the extrusion processing of feed during use, it cannot perform extrusion processing of frozen feed in actual use. Furthermore, when frozen feed is processed, there will still be large particles that cannot be broken down, thus affecting the quality of the final feed. Summary of the Invention

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] Example 1, as Figure 1 and Figure 2As shown, an extrusion device for producing feed additives includes a housing 1, a connecting shell 2 fixedly connected to the upper part of the inner surface of the housing 1, a flow guiding component 3 for guiding flow fixedly installed at the upper end of the connecting shell 2, a crushing and mixing component 4 for stirring feed fixedly installed at the upper end of the flow guiding component 3, and an extrusion component 5 for extrusion fixedly installed at the right end of the housing 1.

[0022] During use, this solution uses a crushing and mixing component 4 to crush and mix frozen feed blocks and additives. After mixing, the feed is fed through the discharge port at the bottom of the crushing and mixing component 4. The mixed feed falls into the guide component 3 and then falls directly onto the top of the extrusion component 5. The extrusion component 5 then strikes the feed that falls onto the top of the extrusion component 5. The striking breaks up any remaining fragments, and the broken feed falls evenly into the conveying chamber of the extrusion component 5. The conveying chamber then feeds the feed into the extrusion chamber, where the extrusion component 5 finally extrudes the feed. The feed is extruded in a long strip shape. During the extrusion process, when the length and weight reach a certain amount, the feed will automatically fall and break, thus completing the extrusion processing of the feed. Therefore, this solution, through the extrusion component 5, can not only extrude the feed, but also, with the assistance of the flow guiding component 3 and the crushing and mixing component 4, can break up the stirred feed, so as to avoid large particles remaining in the feed during the extrusion process and clogging the extrusion port.

[0023] Example 2, as Figure 2 Diagram and Figure 4 As shown, in this embodiment, the flow guiding component 3 includes a barrier 31 fixedly connected to the upper end of the connecting shell 2. A support rod 32 is fixedly connected to the middle of the left side wall and the middle of the right side wall of the inner surface of the barrier 31. A flow guiding platform 33 with a triangular shape is fixedly connected to the upper end of the support rod 32.

[0024] Furthermore, the crushing and mixing component 4 includes a rectangular shell 41, which is fixedly connected to the upper end of the enclosure 31 and communicates with the inner cavity of the enclosure 31. A conical cylinder 42 is fixedly connected to the upper end of the rectangular shell 41. A groove 43 penetrating the front side is opened on the lower rear side of the outer surface of the conical cylinder 42. Two electric baffles 44 are electrically connected to the inner surface of the groove 43. A material discharge port 46 is opened in the middle of the bottom wall of the conical cylinder 42. The upper side of the middle of the front wall of the inner surface of the material discharge port 46 is... A base plate 45 is fixedly connected to the upper middle part of the inner surface rear side wall. An outer frame 47 is fixedly connected to the middle of the upper end of the conical cylinder 42. A motor 48 is fixedly connected to the top wall of the outer frame 47. A discharge opening plate 49 communicating with the inner cavity of the conical cylinder 42 is fixedly connected to the middle of the right side of the upper end of the conical cylinder 42. A stirring blade 40 is rotatably connected to the middle of the upper end of the base plate 45. The output end of the motor 48 passes through the top wall of the conical cylinder 42 and is fixedly connected to the upper end of the stirring blade 40 through a coupling.

[0025] During use, by starting the motor 48, the output end of the motor 48 drives the fixedly connected mixing blade 40 to rotate through the coupling. The lower end of the mixing blade 40 rotates on the upper end of the base plate 45. When the mixing blade 40 rotates, the feed and additives can be put into the conical cylinder 42 from the feed opening plate 49. The feed and additives are crushed and mixed in the conical cylinder 42 by the rotating mixing blade 40. After the feed and additives have been crushed and mixed for a period of time, the electric baffles 44 on both sides can be controlled to slide outward in the inner cavity of the chute 43, so that the crushed and mixed feed falls from the discharge port 46 into the inner cavity of the rectangular shell 41. When the feed falls into the inner cavity of the rectangular shell 41, since the enclosure 31 is connected to the rectangular shell 41 and the guide platform 33 fixedly connected to the upper end of the support rod 32 is triangularly shaped, when the mixed feed falls onto the upper side of the guide platform 33, it will be randomly pushed to both sides by the guide platform 33. The two cavities formed between the inner cavity of the enclosure 31 and the support rod 32 are connected to the connecting shell 2, so that the mixed feed can fall into the inner cavity of the connecting shell 2, completing the initial processing of feed extrusion.

[0026] The two electric baffles 44 mentioned above are electrically connected and installed on the inner surface of the chute 43. Their specific installation method, circuit connection method and control method are all conventional designs. In this solution, it is only necessary to control the two electric baffles 44 to slide outward in the chute 43 when the feed and additives in the inner cavity of the conical cylinder 42 are mixed, so as not to block the feed outlet 46. When crushing and mixing are required, the two electric baffles 44 are controlled to slide inward to block the feed outlet 46. Therefore, the installation and connection method of the two electric baffles 44 mentioned above are all conventional designs in the prior art, so this solution will not elaborate on them.

[0027] The stirring blade 40 mentioned above is a conventional setting in the prior art. In this solution, it is only necessary to ensure that after being fixedly connected to the output end of the motor 48, the motor 48 is started to drive the stirring blade 40 to crush and mix the frozen feed and additives in the inner cavity of the conical cylinder 42. Its specific shape and installation method can be adjusted according to actual production needs, so this solution will not elaborate on it in detail.

[0028] Example 3, as Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, in this embodiment, the extrusion assembly 5 includes a concave box 51 fixedly connected to the right end of the outer shell 1. A support platform 52 with a cavity is fixedly connected to the right end of the concave box 51. A motor 53 is fixedly connected to the bottom wall of the support platform 52. A gear 54 is rotatably connected to the middle of the left side wall of the inner surface of the concave box 51. A gear 55 meshing with gear 54 is rotatably connected to the lower part of the left side wall of the inner surface of the concave box 51. Two meshing gears 56 are rotatably connected to the upper part of the left side wall of the inner surface of the concave box 51. The left middle of the wheel 54, the round rod 50 and the two gears 56 are all fixedly connected to the round rod 50. The outer surface of the round rod 50 fixedly connected to the gear 56 located on the upper front side and the outer surface of the round rod 50 fixedly connected to the gear 54 are all fixedly connected to the pulley 57. The outer surfaces of the two pulleys 57 are all wound with a transmission belt 58. The output end of the support platform 52 passes through the support platform 52 and the concave box 51 and is fixedly connected to the right middle of the pulley 57. The striking component 59 is fixedly installed on the inner surface of the outer shell 1.

[0029] Furthermore, the striking component 59 includes two protruding plates 591. The right ends of both protruding plates 591 are rotatably connected to the left side wall of the inner surface of the connecting shell 2. The right ends of the two protruding plates 591 are respectively fixedly connected to the left ends of the round rods 50 that are fixedly connected to the left ends of the two gears 56. Inclined plates 592 are rotatably connected to the diagonal corners of the left side wall and the right side wall of the inner surface of the connecting shell 2. The two inclined plates 592 are located on the upper side of the protruding plates 591 on the same side. The inclined surfaces of the two inclined plates 592 are respectively fixedly connected to a number of arc-shaped telescopic rods 593 in a linear array with the upper part of the front side wall and the upper part of the rear side wall of the inner surface of the connecting shell 2. The inclined surfaces of the two inclined plates 592 are respectively connected to the inner surface of the shell 2. A number of arc-shaped springs 594 are fixedly connected to the front sidewall and the rear sidewall of the inner surface in a linear array. The arc-shaped springs 594 are located on the outside of the arc-shaped telescopic rods 593 respectively. The middle part of the right side wall of the inner surface of the outer shell 1 and the lower part of the right side wall of the inner surface are rotatably connected to the auger 595. The middle part of the left side wall of the inner surface of the outer shell 1 and the lower part of the left side wall of the inner surface and the lower part of the right side wall of the inner surface are fixedly connected to the cylinder 596. The cylinder 596 on the same side is located on the outside of the auger 595 on the same side. The upper part of the outer surface of the upper cylinder 596 is fixedly connected to the feed box 597 that communicates with its inner cavity. The left end of the lower cylinder 596 is fixedly connected to the extrusion disc 598 with several holes on its surface.

[0030] Furthermore, a hollow connecting box 599 is fixedly connected to the right side of the outer surfaces of the two cylinders 596 that are close to each other, so that their inner cavities can communicate with each other.

[0031] Furthermore, the right ends of both augers 595 are fixedly connected to the left end of the round rod 50 on the same side.

[0032] Furthermore, the two inclined plates 592 are aligned vertically with the two cavities formed between the inner cavity of the enclosure 31 and the support rod 32.

[0033] During use, as can be seen from the above embodiments, the guide table 33 can move the feed that falls onto its surface to both sides at will, and the two inclined plates 592 are aligned vertically with the two cavities formed between the inner cavity of the enclosure 31 and the support rod 32, so the mixed feed will fall onto the surface of the inclined plate 592. During this process, the output end of motor 2 53 can be started, causing the gear 1 54 fixedly connected to it to rotate through the coupling. Gear 1 54 and gear 2 55 mesh with each other, and two pulleys 57 are respectively fixedly connected to the outer surface of the round rod 50 fixedly connected to the left end of gear 1 54 and the outer surface of the round rod 50 fixedly connected to the left end of the pulley 57 located on the front upper side. The outer surfaces of the two pulleys 57 are wrapped with a transmission belt 58. Therefore, when gear 1 54 rotates, one of the gears 3 56 also rotates, and drives the other gear 3 56 meshing with it to rotate. When gear 54 drives two gears 56 to mesh and rotate through pulley 57 and transmission belt 58, the right ends of the two protruding plates 591 are fixedly connected to the round rods 50 on the same side. The two round rods 50 on the upper side pass through the outer shell 1 and the connecting shell 2. Therefore, the two protruding plates 591 rotate continuously. When the protruding plates 591 rotate, the protruding part of their outer surface will push the inclined plate 592 up when it passes under the inclined plate 592. When the inclined plate 592 is pushed up, since the front and rear ends of its upper part are rotatably connected to the left and right walls of the inner surface of the connecting shell 2 respectively, when the inclined plate 592 is pushed up, it will be lifted with the connection point with the connecting shell 2 as the center. At the same time, when the inclined plate 592 is lifted up, the several arc-shaped telescopic rods 593 that are fixedly connected to the lower inclined surface and the inner surface of the connecting shell 2 will be stretched, and the several arc-shaped springs 594 will also be stretched. When the protruding part of the convex plate 591 leaves the underside of the inclined plate 592, the several arc springs 594 on both sides are no longer subjected to tensile force, so the inclined plate 592 on the same side can be pulled back to the initial state, and the arc telescopic rod 593 on the same side retracts to the initial state. Therefore, the rotating and pressing action of the two convex plates 591 on both sides against the inclined plate 592 on the same side causes the two inclined plates 592 to swing up and down continuously, thereby striking the feed falling onto their surface and further breaking up any remaining lumps of feed. The broken feed then falls from the feed box 597 into the inner cavity of the central cylinder 596. The auger 595 in the center is connected to the round rod 50 fixedly connected to the left end of the gear 54. Therefore, when the auger 595 rotates, it can transport the feed to the right. During the transportation process, the feed... The feed is squeezed from the hollow connecting box 599 into the inner cavity of the lower cylinder 596. The second gear 55 meshes with the first gear 54, so the rotation direction of the second gear 55 is opposite to that of the first gear 54. Therefore, the round rod 50 fixedly connected to the left end of the second gear 55 drives the auger 595 fixedly connected to it to rotate, so that the auger 595 located on the lower side transports the feed to the left and finally squeezes it out from the hole of the extrusion disc 598. When the feed is squeezed out to a certain length, it will break off by its own weight, thus completing the extrusion processing of the feed.

[0034] During the overall extrusion process, since the feed is made from frozen feed blocks, some of it will melt during the mixing and extrusion process in the device, thus meeting the conditions for the feed to be extruded in strip form.

[0035] It should be noted that the specific installation method, circuit connection method, and control method of the motor 48 and support platform 52 used in this invention are all conventional designs, and will not be described in detail here.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
