Description

Technical Field

[0001] The present invention relates to the technical field of feed processing, and in particular to equipment and a method for removing impurities from animal feed used in animal husbandry. Background Art

[0002] Feed is the general term for food for animals raised by humans. Generally, feed mainly refers to the food of animals raised in agriculture or animal husbandry. Feed includes more than ten varieties of feed raw materials such as soybeans, soybean meal, corn, and fish meal.

[0003] Before processing, the raw materials need to be removed and filtered to improve the quality of the feed. A feed production filtering device disclosed in announcement number CN216988534U includes a mounting frame, a bracket and a filter; the bracket is arranged on the mounting frame, and a supporting foot is arranged at the bottom of the mounting frame; the supporting foot is in contact with the ground; a chassis and a controller are arranged on the mounting frame; a plurality of power supply lines and signal lines connected to the filter are arranged on the controller; the chassis covers the power supply lines and signal lines; the bracket is a circular frame; the middle part of the bracket is hollow, and a contact ring is arranged at the bottom of the bracket; the contact ring extends toward the hollow part in the middle of the bracket; the bracket is provided with symmetrical drivers a and drivers b along the inner wall of the circular ring; the filter is arranged on the bracket; the bottom of the filter is overlapped on the contact ring of the bracket; a filter screen is provided on the filter, and the filter screen is a detachable structure. The present application drives the filter to operate by magnetic attraction to generate vibration; compared with the method of using a vibration motor to drive the operation, it is more energy-saving and has less noise; at the same time, the vibration amplitude is larger and the filtering effect is better.

[0004] In the prior art, a detachable filter screen is used to facilitate filtering and removing impurities from different feeds. However, in actual work, it is found that the feed raw materials may contain moldy grains and impurities of the same particle size as the raw materials. Due to the equal particle size, the filter screen cannot filter out these impurities during filtration, resulting in the moldy grains and other impurities remaining in the raw materials, affecting the quality of the feed. In addition, the moldy grains will cause the feed to deteriorate when it is made. Summary of the Invention

[0023] S4, during gravity separation, air is blown into the impurity removal bin through the air duct, and the raw materials will be separated under the impact of vibration and airflow, thereby separating the diseased raw materials from the raw materials.

[0024] Beneficial effects of the present invention:

[0025] (1) The present invention can filter out fine impurities in corn before separating moldy kernels by setting up the filter plate, so as to avoid a large amount of fine impurities clogging the sieve plate 1 and the sieve plate 2 and affecting the blowing effect. At the same time, through the effects of wind force and vibration, corns with the same particle size but different qualities can be separated, and the quality difference between the two can be used to separate the moldy kernels. Compared with traditional filtration, the separation of moldy kernels can be achieved faster, and the separation effect is improved.

[0026] (2) After the corn in the present invention is filtered by the filter plate, smaller impurities will fall onto the waste plate below. The waste plate is provided with holes, and the holes are relatively large. Small impurities will pass through the holes to the inclined plate below and be discharged through the inclined plate. However, during the filtration, some good corns may also be filtered to the bottom. These good corns are large and small. The smaller corns may pass through the waste plate and be discharged together with the impurities, while the remaining corns will slide into the transfer bin and then slide from the transfer bin and the down slide to the circulation bin. Then the circulation shaft rotates, and the circulation blades will be used to lift the corn to a high place during the rotation. Then, the corn will slide again into the impurity removal bin through the upper slide and fall onto the filter plate. It will be filtered again or swept to the middle plate by the cleaning plate. By setting the circulation bin, the corn can be filtered again, avoiding the good corn from being discharged together with the impurities, thereby improving the yield rate.

[0027] (3) The filtering motor in the present invention drives the rotating shaft to rotate, and the filter plate is used to perform filtering work while rotating. At the same time, the rotating shaft will drive the external driving pulley to rotate when rotating, and will drive the driven pulley to rotate through the driving belt when rotating, and then drive the transmission rod and the transmission gear to rotate. When the transmission gear rotates, it will drive the driving gear on the top of the circulation bin to rotate. When the driving gear rotates, it will drive the driven gear meshed at the other end to rotate, thereby driving pulley one and the connecting belt to rotate, and then using the connecting belt to drive pulley two to rotate, thereby driving the inertia shaft and inertia plate inside the glide path to rotate. Due to the large amount of filtration, more impurities and corn will be filtered out. When some corn enters the glide path, due to the narrow glide path, it may block the glide path. By driving the inertia plate to rotate, the internal corn can be dredged, thereby avoiding blockage inside the glide path. At the same time, when the driving gear rotates, it also drives the circulation shaft to rotate, realizing the circulation of corn.

[0028] (4) The corn in the present invention that enters the downhill channel can drive the inertia plate to rotate, thereby driving the inertia shaft to rotate. During the rotation, the inertia shaft will drive the external pulley 2 to rotate, thereby utilizing the connecting belt to drive the pulley 1 and the driven gear to rotate, and then utilizing the driven gear to drive the driving gear to rotate, thereby driving the circulation shaft to rotate, thereby realizing the circulation of corn. The two groups of circulation bins are driven to rotate by two different groups of inertia plates. The side with more corn inside the downhill channel has a faster rotation speed of the circulation shaft on that side. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0041] See also Figures 1-9 As shown, the present application provides a livestock feed impurity removal device for livestock breeding, comprising a feeding mechanism 1, an impurity removal mechanism 2 and a circulation mechanism 3, and also comprising:

[0042] The feeding mechanism 1 includes a feeding bin 11, which is arranged on one side of the impurity removal mechanism 2;

[0043] The impurity removal mechanism 2 includes an impurity removal bin 21, which is arranged below the loading bin 11;

[0044] The circulation mechanism 3 includes a circulation bin 31, which is arranged on both sides of the impurity removal bin 21;

[0045] After the feed raw materials are loaded from the feeding bin 11 into the impurity removal bin 21, the raw materials are subjected to impurity removal in the impurity removal bin 21. During the impurity removal process, part of the raw materials will enter the circulation bin 31, and then re-enter the impurity removal bin 21 through the circulation bin 31 for impurity removal, and finally the impurity-removed feed raw materials are discharged;

[0046] During operation, the raw materials of the feed generally need to be processed before being made. The raw materials for the feed to be removed by impurities in this application can be corn, or other raw materials such as soybeans, but this equipment will first be illustrated using corn as an example. After the corn is put into the feeding bin 11, the corn is slowly put into the impurity removal bin 21 again through the feeding bin 11 for impurity removal. During the process, the circulation bin 31 can perform a circulation filtering work on the corn to prevent good corn from being cleared out together with impurities, and then the moldy grains are separated and processed, and finally the corn feed after impurities are obtained.

[0047] like Figure 2 As shown, a feed port 211 is provided on the top of the impurity removal bin 21; a triangular plate 2111 is fixedly connected to the side wall of the impurity removal bin 21; the triangular plate 2111 is arranged below the feed port 211; a rotating shaft 212 is rotatably connected to the side wall of the impurity removal bin 21; two groups of rotating shafts 212 are provided; a cleaning plate 2121 is fixedly connected to the rotating shaft 212; a filter plate 22 and a middle plate 221 are fixedly connected to the side wall of the impurity removal bin 21; two groups of filter plates 22 are provided, which are respectively arranged below the cleaning plates 2121; two groups of middle plates 221 are provided, which are located in the middle of the impurity removal bin 21 and below the triangular plate 2111; a vibrator 241 is fixedly connected to the side wall of the impurity removal bin 21; a sieve plate 1 24 and a sieve plate 2 26 are respectively fixedly connected to the vibrator 241; the sieve plate 1 24 is located below the middle plate 221; The sieve plate 26 is located below the sieve plate 1 24; a transfer chute 242 is fixedly connected to the side wall of the debris removal bin 21; one end of the transfer chute 242 is parallel to the sieve plate 1 24, and the other end is located above the sieve plate 26; a partition 243 and a spoiler 25 are fixedly connected to the side wall of the debris removal bin 21; the spoiler 25 is provided with multiple groups, respectively located below the sieve plate 1 24 and the sieve plate 2 26; an air outlet 252 is provided on the spoiler 25; an air duct 251 is fixedly connected to the side wall of the debris removal bin 21; the air duct 251 is connected to the debris removal bin 21; a waste chute 1 244 and a waste chute 2 262 are fixedly connected to the side wall of the debris removal bin 21; the waste chute 1 244 is arranged parallel to the sieve plate 1 24; the waste chute 262 is arranged parallel to the sieve plate 26; a discharge port 261 is provided on the side wall of the debris removal bin 21;

[0048] During operation, when the corn reaches the impurity removal bin 21 from the feed port 211, it will be blocked by the triangular plate 2111, and then guided to the filter plates 22 on both sides through the triangular plate 2111, and then the rotating shaft 212 is driven to rotate, which will drive the cleaning plate 2121 to rotate counterclockwise in the filter plate 22. During the rotation, the cleaning plate 2121 will drive the corn to move in the filter plate 22. During the movement, the fine impurities in the corn can be filtered by the filter plate 22, and the large grains of corn will be swept to the middle plate 221, from The middle plate 221 falls onto the sieve plate 24 below. When it reaches the sieve plate 24, the vibrator 241 below is started. Then the vibrator 241 drives the sieve plate 24 to vibrate. While vibrating, air is blown to the bottom of the sieve plate 24 through the air duct 251, and then the wind is blown onto the sieve plate 24 through the spoiler 25. There are multiple groups of spoilers 25, and the spoilers 25 arranged at the rear are fed with air through the air port 252. Under the simultaneous operation of vibration and blowing, the corn will gradually be separated into layers. Good corn is heavier due to its quality. During vibration, it will gradually approach the bottom, while the moldy kernels, due to their lighter weight, will gradually float on the good corn kernels during the vibration process. At the same time, the sieve plate 1 24 is set at an angle. During the vibration process, the moldy kernels at the top will move upwards, that is, move to the waste chute 1 244, while the good corn will move downwards and reach the transfer channel, and then flow to the sieve plate 2 26 below, and be separated again through the sieve plate 2 26, thereby improving the impurity removal effect. Among them, the moldy kernels separated by the sieve plate 26 will be cleared out from the waste chute 2 262. Through the setting of the filter plate 22, the fine impurities in the corn can be filtered before separating the moldy kernels, avoiding a large amount of fine impurities from clogging the sieve plate 1 24 and the sieve plate 2 26, affecting the blowing effect. At the same time, through the effects of wind and vibration, corns with the same particle size but different qualities can be separated, and the quality difference between the two is utilized to achieve the separation of the moldy kernels. Compared with traditional filtration, the separation of the moldy kernels is achieved faster and the separation effect is improved.

[0049] like Figure 2 As shown, the top of the circulation bin 31 is rotatably connected to the circulation shaft 32; the circulation blade 33 is fixedly connected to the circulation shaft 32; the side wall of the circulation bin 31 is fixedly connected to the upper slide 36 and the lower slide 37; the upper slide 36 and the lower slide 37 are connected to the impurity removal bin 21; the side wall of the impurity removal bin 21 is fixedly connected to the waste plate 23; the waste plate 23 is provided with two groups; the side wall of the impurity removal bin 21 is fixedly connected to the inclined plate 231; the inclined plate 231 is provided with two groups, both of which are located below the waste plate 23; the side wall of the impurity removal bin 21 is fixedly connected to the transfer bin 232; the transfer bin 232 is provided with two groups, which are arranged parallel to the waste plate 23; the end of the lower slide 37 away from the circulation bin 31 is fixedly connected to the transfer bin 232; the upper slide 36 is located above the filter plate 22;

[0050] During operation, after the corn is filtered by the filter plate 22, smaller impurities will fall onto the waste plate 23 below. There are holes on the waste plate 23, and the holes are large. Fine impurities will pass through the holes and reach the inclined plate 231 below, and be discharged through the inclined plate 231. However, during filtering, some good corn may also be filtered to the bottom. These good corns are large and small. Smaller corns may pass through the waste plate 23 and be discharged together with the impurities, while the remaining corn will slide into the transfer bin 232, and then slide from the transfer bin 232 and the lower slide 37 to the circulation bin 31. Then the circulation shaft 32 rotates, and during rotation, the circulation blades 33 will be used to lift the corn to a high place, and then slide again into the impurity removal bin 21 through the upper slide 36, fall onto the filter plate 22, and be filtered again or swept to the middle plate 221 by the cleaning plate 2121. Through the setting of the circulation bin 31, the corn can be filtered again to avoid good corn being discharged together with impurities, thereby improving the yield rate.

[0051] like Figure 2-Figure 4 As shown, the side wall of the loading bin 11 is rotatably connected to a pulley shaft 12; two groups of pulley shafts 12 are provided; a loading belt 13 is sleeved on the pulley shaft 12; a groove 14 is opened in the middle of the loading belt 13; a loading box 15 is hinged in the groove 14; there are multiple groups of loading boxes 15; a discharge chute 17 and a feed chute 16 are fixedly connected to the side wall of the loading bin 11; the discharge chute 17 is provided above the feed port 211;

[0052] During operation, the corn is poured into the feed chute 16, and then the corn will slide into the upper hopper 11 and fall into the loading box 15. The pulley shaft 12 is then driven to rotate, which will drive the loading belt 13 and the loading box 15 to move, and the loading box 15 containing corn is moved to the top and then turned over, so that the corn in the loading box 15 is poured into the discharge chute 17, and then flows to the feed port 211 through the discharge chute 17, and then the impurity removal work is carried out. Through the setting of the loading hopper 11, the feeding of corn can be controlled to achieve intermittent feeding, thereby avoiding the blockage of the filter plate 22 and the screen plate caused by one-time feeding.

[0053] like Figure 2 As shown, the cleaning plate 2121 is in flexible contact with the filter plate 22; the vibrator 241 is provided in two groups, each group is provided with two, and is respectively provided at both ends of the impurity removal bin 21;

[0054] During operation, the cleaning plate 2121 drives the corn feed to move, and the corn feed is filtered during the movement. At the same time, the vibrator 241 drives the sieve plate 1 24 and the sieve plate 2 26 to vibrate, thereby separating the corn feed.

[0055] like Figure 7As shown, the top of the circulation bin 31 is rotatably connected to the driving gear 34; the output end of the driving gear 34 is fixedly connected to the input end of the circulation shaft 32; the side wall of the circulation bin 31 is rotatably connected to the driven gear 38 and the pulley 1 381; the driven gear 38 is meshed with the driving gear 34; a connecting belt 382 is sleeved on the driven gear 38; the side wall of the lower slide 37 is rotatably connected to the inertia shaft 371; the inertia plate 372 is fixedly connected to the inertia shaft 371; there are multiple groups of inertia plates 372; the outer wall of the lower slide 37 is rotatably connected to the pulley 2 383; the output end of the pulley 2 383 is fixedly connected to the input end of the inertia shaft 371; the end of the connecting belt 382 away from the pulley 1 381 is sleeved on the pulley 2 383; the debris removal bin 2 The outer wall of the circulation chamber 31 is rotatably connected to the driving pulley 28; a driving belt 281 is sleeved on the driving pulley 28; a transmission rod 39 is rotatably connected to the side of the circulation chamber 31 away from the driving gear 34; a transmission gear 283 and a driven pulley 282 are fixedly connected to the transmission rod 39; the end of the driving gear 34 away from the driven gear 38 is meshed with the driving gear 283; the end of the driving belt 281 away from the driving pulley 28 is sleeved on the driven pulley 282; the side wall of the impurity removal chamber 21 is fixedly connected to the filter motor 4; the rotating shaft 212 is driven by the filter motor 4; the input end of the driving pulley 28 is fixedly connected to the output end of the rotating shaft 212; the side wall of the loading chamber 11 is fixedly connected to the loading motor 19; the pulley shaft 12 is driven by the loading motor 19;

[0056] During operation, the filter motor 4 drives the rotating shaft 212 to rotate, and the filter plate 22 is used for filtering while rotating. At the same time, the rotating shaft 212 drives the external driving pulley 28 to rotate, and the driven pulley 282 is driven to rotate through the driving belt 281, thereby driving the transmission rod 39 and the transmission gear 283 to rotate. When the transmission gear 283 rotates, it drives the driving gear 34 at the top of the circulation bin 31 to rotate. When the driving gear 34 rotates, it drives the driven gear 38 meshed at the other end to rotate, thereby driving the pulley 381 and the connecting belt 38. 2 rotates, and then the connecting belt 382 drives the pulley 2 383 to rotate, thereby driving the inertia shaft 371 and the inertia plate 372 inside the downhill slide 37 to rotate. Due to the large amount of filtration, more impurities and corn are filtered out. When some corn enters the downhill slide 37, the downhill slide 37 is narrow and may be blocked. By driving the inertia plate 372 to rotate, the corn inside can be dredged, thereby avoiding blockage inside the downhill slide 37. At the same time, when the driving gear 34 rotates, it also drives the circulation shaft 32 to rotate, realizing the circulation of corn.

[0057] like Figure 2 As shown, the bottom of the loading bin 11 is movably connected to a discharge plate 18; the bottom of the circulation bin 31 is movably connected to a chassis 35; the bottom of the impurity removal bin 21 is movably connected to a movable bottom plate 27; a waste opening 233 is opened on the side wall of the impurity removal bin 21; the waste opening 233 is arranged parallel to the inclined plate 231;

[0058] During operation, after the work is finished, the remaining feed can be cleaned out by opening the discharge plate 18, the bottom plate 35 and the movable bottom plate 27, and the impurities at the inclined plate 231 can be discharged from the waste port 233.

[0059] See also Figures 1-9 As shown, the present application provides a method for removing impurities from livestock feed for animal husbandry, comprising the following steps:

[0060] S1, the feed material slides into the loading box 15 through the feeding chute 16, and then the material is poured onto the discharging chute 17 through the loading box 15, and then slides into the impurity removal bin 21;

[0061] S2, the raw materials enter the impurity removal bin 21 and fall onto the filter plate 22, then the cleaning plate 2121 is driven to rotate, and the cleaning plate 2121 drives the raw materials to be filtered on the filter plate 22. After filtration, the cleaning plate 2121 sweeps the raw materials into the middle plate 221, and then falls onto the sieve plate 1 24;

[0064] During operation, the feed raw materials slide into the loading box 15 through the feeding chute 16, and then are poured onto the discharging chute 17 through the loading box 15, and then slide into the impurity removal bin 21. After entering the impurity removal bin 21, the raw materials fall onto the filter plate 22, and then the cleaning plate 2121 is driven to rotate, and the cleaning plate 2121 is used to drive the raw materials to be filtered on the filter plate 22. After filtration, the cleaning plate 2121 sweeps the raw materials into the middle plate 221, and then falls onto the sieve plate 1 24. The sieve plate 1 24 separates the raw materials by specific gravity, and the waste materials are discharged from the waste chute 1 244, and the good materials slide to the sieve plate 2 26 through the transfer chute 242 for secondary separation. The good materials are discharged from the discharge port 261, and the waste materials are discharged from the waste chute 2 262.

The raw materials will be separated under the impact of vibration and airflow, thereby separating the pathological raw materials in the raw materials.

[0065] The working principle of the present invention is as follows: when the corn reaches the impurity removal bin 21 from the feed inlet 211, it will be blocked by the triangular plate 2111, and then guided to the filter plates 22 on both sides through the triangular plate 2111, and then the rotating shaft 212 is driven to rotate, and the rotation will drive the cleaning plate 2121 to rotate counterclockwise in the filter plate 22. During the rotation, the cleaning plate 2121 will drive the corn to move in the filter plate 22. In the process of movement, fine impurities in the corn can be filtered by the filter plate 22, while large grains of corn are swept to the middle plate 221, and fall from the middle plate 221 onto the lower screen plate 24. When it reaches the screen plate 24, the vibrator 241 below is started, and then the vibrator 241 drives the screen plate 24 to vibrate. While vibrating, air is blown to the bottom of the screen plate 24 through the air duct 251, and then the wind is blown out through the spoiler 25. To the sieve plate 1 24, wherein there are multiple groups of spoilers 25, and the spoilers 25 arranged at the rear are fed with air through the air inlet 252. Under the simultaneous operation of vibration and blowing, the corn will gradually be stratified. Good corn, due to its heavier weight, will gradually approach the bottom during vibration, while moldy grains, due to its lighter weight, will gradually float on the good corn grains during vibration. At the same time, the sieve plate 1 24 is tilted. During vibration, the moldy grains at the top will move upward, that is, to the waste chute 1 244, while the good corn will move downward and reach the transfer channel, and then flow to the sieve plate 2 26 below, and undergo separation again through the sieve plate 26, thereby improving the impurity removal effect. Among them, the moldy grains separated by the sieve plate 26 will be cleared out from the waste chute 2 262.

[0066] Among them, after the corn is filtered by the filter plate 22, smaller impurities will fall onto the waste plate 23 below. There are holes on the waste plate 23, and the holes are large. Small impurities will pass through the holes to the inclined plate 231 below and be discharged through the inclined plate 231. However, during the filtration, some good corn may also be filtered to the bottom. These good corns are large and small. Smaller corns may pass through the waste plate 23 and be discharged together with the impurities, while the remaining corn will slide into the transfer bin 232, and then slide from the transfer bin 232 and the lower slide 37 to the circulation bin 31. Then the circulation shaft 32 rotates, and the circulation blades 33 will be used to lift the corn to a high place during rotation, and then slide again into the impurity removal bin 21 through the upper slide 36, fall onto the filter plate 22, and be filtered again or be swept to the middle plate 221 by the cleaning plate 2121.

All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
