Description

Technical Field

[0001] This invention relates to the technical field of feed processing, and in particular to a clumping and dispersing structure for fermented shrimp feed and its application method. Background Technology

[0002] Fermented shrimp feed is a type of aquaculture feed that improves the nutritional value and palatability of feed ingredients through microbial fermentation, while also enhancing the health and growth efficiency of shrimp.

[0003] During storage, feed may clump together due to stacking, compression, moisture absorption, and fermentation. This makes the feed difficult to pour or feed. Existing feed clump breaking structures typically pour all the feed in directly, breaking up both clumped and non-clumped feed. However, this method is relatively simple and cannot simultaneously finely screen the broken feed, resulting in poor grinding effect and reduced processing efficiency. Summary of the Invention

[0032] A filter screen, which is embedded at the bottom of the screening box, is used to screen out impurities in the feed.

[0033] A transmission assembly is disposed between the rotating drum and the screening box.

[0034] Preferably, the transmission assembly includes:

[0039] The second compression spring is sleeved on the outside of the fixed rod. One end of the second compression spring is fixedly connected to the fixed rod, and the other end of the second compression spring is fixedly connected to the C-shaped rod.

[0040] Preferably, the outer wall of the machine body is rotatably equipped with a door for disassembling and assembling the screening box.

[0041] Preferably, a drying lamp is fixedly installed at the bottom of the first fixed frame for drying the broken feed, and a feed box is slidably connected to the outer wall of the machine body for collecting the dried and broken feed.

[0042] This invention also provides a method for using the agglomerated and disintegrated structure of shrimp fermented feed, including the following specific steps:

[0043] Step 1: When breaking up the feed, first start the first motor and the second motor. The first motor can make the worm drive the worm wheel to rotate, which can make the drum rotate on the second fixed frame and drive the first breaking bar inside to rotate. The second motor can drive the second breaking bar on the rotating rod to rotate in the opposite direction to the first breaking bar. At this time, the feed can be added into the machine body from the feed pipe.

[0044] Step 2: While the drum is rotating, the top of the lifting rod is in contact with the primary filter plate, and the bottom of the lifting rod is pressed against the bottom of the inner wall of the annular groove under the elastic force of the first compression spring. As the fixed ring rotates with the drum, the annular grooves of varying depths can be used to drive the lifting rod to move back and forth in the vertical direction. This causes the primary filter plate to rotate up and down and shake the feed on it, so that the primary filter plate can perform initial screening of the feed entering the machine. At the same time, the shaking can make the clumped feed enter the collection hopper more quickly.

[0045] Step 3: When the drum is rotating, its feed inlet will coincide with the discharge outlet of the collection hopper every time it rotates once, so that the agglomerated feed can be fed intermittently. The agglomerated feed that enters the drum will be broken up by the first and second breaking rods rotating in opposite directions and fall into the screening box with the guide bucket.

[0046] Step 4: While the drum is rotating, the eccentric ring squeezes one end of the C-shaped rod, which allows the locking block and the elastic force of the second compression spring to pull or push the screening box, causing the screening box to move back and forth in the horizontal direction. This allows for secondary screening of the feed initially screened by the primary filter plate and the broken feed. At the same time as screening, the drying lamp is activated to dry the feed, remove larger impurities, and allow the dried feed to fall into the feed box.

[0047] The technical effects and advantages of this invention are as follows:

[0048] (1) The present invention utilizes a combination of a primary filter plate, a collection hopper, a rotating drum, a dispersing mechanism, a lifting mechanism, and a filtering mechanism. By rotating the rotating drum and the dispersing mechanism in opposite directions, the clumps of feed entering the rotating drum can be dispersed. At the same time, the lifting mechanism can shake the primary filter plate up and down, thereby performing a primary screening of the feed entering the machine. The clumps of feed will enter the collection hopper with the shaking, while the unclumped feed will fall into the filtering mechanism together with the dispersed feed for screening. This allows the feed to be screened multiple times at the same time, resulting in a better dispersing effect and improving the processing efficiency of feed dispersing.

[0049] (2) The present invention utilizes a combination of a fixed ring, a lifting rod, a squeezing plate and a first compression spring. While the rotating drum is breaking up the agglomerated feed, it can drive the fixed ring to rotate. The lifting rod can push the rotatable primary filter plate through the annular groove with varying depth, thereby performing primary screening on the feed entering the machine. The agglomerated feed will enter the collection hopper with the shaking, while the unagglomerated feed will fall directly with the primary screen, thereby improving the processing efficiency of feed breaking up.

[0050] (3) The present invention utilizes the combination of guide bucket, screening box, filter screen and transmission component. While the rotating drum breaks up the agglomerated feed, the transmission component drives the screening box to move back and forth in the horizontal direction. This allows for the screening of the unagglomerated feed and the broken feed screened out by the primary filter plate, thereby removing larger impurities from the feed and improving the palatability of the feed and the digestibility and absorption rate of the shrimp.

[0061] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0062] This invention provides, for example Figure 1-9 The above-dispersed structure for fermented shrimp feed includes a body 1, with a feed pipe 2 fixedly connected to the top of the body 1. The feed pipe 2 can transport the feed into the interior of the body 1.

[0063] Furthermore, the machine body 1 is equipped with an agglomeration and dispersing filtration device, which includes: a primary filter plate 3, a collection hopper 4, a rotating drum 5, a dispersing mechanism 6, a lifting mechanism 7, and a filtration mechanism 8. The primary filter plate 3 is rotatably mounted inside the machine body 1 via a rotating shaft. The primary filter plate 3 is inclined, with its higher side located below the feed pipe 2. This allows the feed to roll on the primary filter plate 3 using its own weight, causing agglomerated feed to fall into the collection hopper 4, while unagglomerated feed is screened and falls through. This ensures that the dispersing mechanism 6 only disperses agglomerated feed. The processing improves the efficiency of feed dispersing; the collecting hopper 4 is fixedly connected to the inner wall of the machine body 1, and the top of the collecting hopper 4 is provided with a groove for feeding. The collecting hopper 4 is used to collect the agglomerated feed that has been initially screened and guide it into the interior of the rotating drum 5; the rotating drum 5 is located at the bottom of the collecting hopper 4, and the top of the rotating drum 5 is provided with a feeding port; the dispersing mechanism 6 is located inside the rotating drum 5 and is used to beat the agglomerated feed; the lifting mechanism 7 is located outside the rotating drum 5 and is used to drive the primary filter plate 3 to shake; the filtering mechanism 8 is located inside the machine body 1 and is used to screen the dispersed feed.

[0064] Furthermore, a first fixed frame 9 is fixedly connected to the inner wall of the machine body 1. The lifting mechanism 7 cooperates with the first fixed frame 9. The top of the first fixed frame 9 is provided with an inclined surface. The inclined surface facilitates that the feed initially screened by the primary filter plate 3 can completely enter the interior of the filter mechanism 8 without remaining on the first fixed frame 9. A second fixed frame 10 is fixedly connected to the inner wall of the machine body 1. The rotating drum 5 is rotatably disposed inside the second fixed frame 10.

[0065] Specifically, the dispersing mechanism 6 includes: a first motor 61, a worm gear 62, a worm wheel 63, and first dispersing rods 64. The first motor 61 is fixedly installed on the outer wall of the machine body 1. Both ends of the worm gear 62 are rotatably connected to the inner wall of the machine body 1, and the output end of the first motor 61 is connected to one end of the worm gear 62. The worm wheel 63 is fixedly sleeved on the outside of the rotating drum 5, and the worm wheel 63 is meshed with the worm gear 62. Multiple first dispersing rods 64 are equidistantly fixed to the inner wall of the rotating drum 5 and arranged in a ring. By starting the first motor 61, the worm gear 62 can drive the worm wheel 63 to rotate, thereby causing the rotating drum 5 to rotate on the second fixed frame 10 and drive the internal first dispersing rods 64 to rotate. When the rotating drum 5 rotates, its feed inlet will coincide with the discharge outlet of the collection hopper 4 every one revolution, so that the agglomerated feed can be fed intermittently to prevent excessive feeding at one time from causing blockage.

[0066] Furthermore, the dispersing mechanism 6 also includes: a mounting frame 65, a second motor 66, a rotating rod 67, and a second dispersing bar 68. The mounting frame 65 is fixedly connected to the inside of the machine body 1; the second motor 66 is fixedly installed inside the mounting frame 65, and both the first motor 61 and the second motor 66 are electrically connected to an external power supply through an external switch; both ends of the rotating rod 67 are rotatably inserted and connected to the inner wall of the rotating drum 5, and the output end of the second motor 66 is drivenly connected to one end of the rotating rod 67; multiple second dispersing bars 68 are equidistantly fixedly connected to the outer wall of the rotating rod 67, and multiple first dispersing bars 64 and multiple second dispersing bars 68 are staggered. When the first motor 61 is started, the second motor 66 is started simultaneously. The second motor 66 can drive the second dispersing bars 68 on the rotating rod 67 to rotate in the opposite direction to the rotating drum 5, so that the first dispersing bars 64 and the second dispersing bars 68 can better disperse the clumped feed.

[0067] Specifically, the lifting mechanism 7 includes: a fixing ring 71, a lifting rod 72, a pressing plate 73, and a first compression spring 74. The fixing ring 71 is fixedly sleeved on the outer wall of the rotating drum 5. An annular groove is formed at the top of the fixing ring 71, and the depth of the annular groove varies at different positions. If the annular groove is unfolded, it will be wavy. One end of the lifting rod 72 is attached to the bottom end of the primary filter plate 3 and is slidably inserted into the first fixing frame 9. The other end of the lifting rod 72 is slidably inserted into the inner cavity of the annular groove. The pressing plate 73 is fixedly inserted into the lifting rod 72. The first compression spring 74 is sleeved on the outside of the lifting rod 72. One end of the first compression spring 74 is fixedly connected to the pressing plate 73, and the other end of the first compression spring 74 is fixedly connected to the pressing plate 73. A fixed frame 9 is fixedly connected to the inner wall, and the first compression spring 74 is always in a compressed state. Thus, the extrusion plate 73 can exert a stable downward elastic force on the lifting rod 72. This allows the top end of the lifting rod 72 to be in contact with the primary filter plate 3, while the bottom end of the lifting rod 72 can be in close contact with the bottom end of the inner wall of the annular groove. When the fixed ring 71 rotates, the annular grooves of varying depths can drive the lifting rod 72 to move back and forth in the vertical direction. This can drive the primary filter plate 3 to rotate up and down and shake the feed on it, making the screening effect of the primary filter plate 3 better. At the same time, the shaking can also make the clumped feed enter the interior of the collection hopper 4 more quickly.

[0068] Specifically, the filtration mechanism 8 includes: a guide bucket 81, a screening box 82, a filter screen 83, and a transmission assembly 84. The guide bucket 81 is fixedly connected to the inside of the machine body 1. The top of the guide bucket 81 has an inclined surface, which can guide the feed screened by the primary filter plate 3 and the broken feed into the inside of the screening box 82. The bottom has an opening, which can allow the screened feed to fall into the inside of the feed box 13. The screening box 82 is slidably inserted into the inner cavity of the guide bucket 81. The filter screen 83 is embedded in the bottom of the screening box 82 and is used to screen out impurities in the feed. The transmission assembly 84 is located between the rotating drum 5 and the screening box 82.

[0069] Furthermore, the transmission assembly 84 includes: an eccentric ring 841, a fixed rod 842, a C-shaped rod 843, a locking block 844, and a second compression spring 845. The eccentric ring 841 is fixedly sleeved on the outside of the rotating drum 5; the fixed rod 842 is fixedly connected to one side of the machine body 1; both ends of the C-shaped rod 843 are slidably inserted into the machine body 1, and the middle part of the C-shaped rod 843 is slidably inserted into the fixed rod 842; the locking block 844 is fixedly connected to one end of the C-shaped rod 843, and a locking groove is provided on one side of the screening box 82. The locking block 844 is slidably inserted into the inner cavity of the locking groove. The cross-section of the locking groove is T-shaped. The locking block 844 is used to pull and push the screening box 82. A door 11 is rotatably installed on the outer wall of the machine body 1 for disassembling and assembling the screening box 82. By opening the door 11, the screening box 82 can be moved from the inside of the guide hopper 81. Remove; the second compression spring 845 is sleeved on the outside of the fixed rod 842. One end of the second compression spring 845 is fixedly connected to the fixed rod 842, and the other end of the second compression spring 845 is fixedly connected to the C-shaped rod 843. The second compression spring 845 is always in a compressed state, so that it can provide a stable elastic force to the C-shaped rod 843, so that one end of the C-shaped rod 843 can be tightly attached to the eccentric ring 841. So that while the rotating drum 5 is rotating, the eccentric ring 841 can squeeze one end of the C-shaped rod 843, so that the locking block 844 can pull the screening box 82 to move back and forth in the horizontal direction, so that the feed initially screened by the primary filter plate 3 and the broken feed can be screened again to remove larger impurities. Larger impurities may affect the taste of the feed and make shrimp unwilling to eat it. Removing these impurities can improve the palatability of the feed, promote shrimp feeding, and ensure that they obtain sufficient nutrition. The feed may contain indigestible components, which may cause indigestion in shrimp. Removing these impurities can improve the palatability of the feed and the shrimp's digestibility and absorption rate, making it easier to use.

[0070] Furthermore, a drying lamp 12 is fixedly installed at the bottom of the first fixed frame 9 for drying the broken feed. The drying lamp 12 dries the falling feed to prevent the damp feed from accumulating and clumping again after screening. A feed box 13 is slidably inserted and connected to the outer wall of the machine body 1 for collecting the dried and broken feed.

[0071] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

The method of claim 7, wherein the method further comprises: The following specific use steps are included: Step one: when the feed is scattered, first start the first motor (61) and the second motor (66), the first motor (66) can drive the worm gear (63) to rotate, so that the rotating drum (5) can rotate on the second fixing frame (10) and drive the first scattering rod (64) inside to rotate, the second motor (66) can drive the second scattering rod (68) on the rotating rod (67) to rotate in the opposite direction of the first scattering rod (64), at this time the feed can be added from the feed pipe (2) to the inside of the machine body (1); Step two: while the rotating drum (5) is rotating, the top end of the jacking rod (72) is in close contact with the primary filter plate (3), and the bottom end of the jacking rod (72) is in close contact with the bottom end of the annular groove inner wall under the elastic force of the first compression spring (74), so that when the fixing ring (71) rotates with the rotating drum (5), the jacking rod (72) can be driven to reciprocate in the vertical direction by the annular grooves with different depths, so as to drive the primary filter plate (3) to rotate up and down, and shake the feed on it, so that the primary filter plate (3) can screen the feed entering the machine body (1), and at the same time, the agglomerated feed can enter the inside of the collecting hopper (4) faster; Step three: when the rotating drum (5) rotates, the feed inlet will coincide with the discharge port of the collecting hopper (4) every time it rotates one revolution, so that the agglomerated feed can be intermittently discharged, and the agglomerated feed entering the rotating drum (5) will be scattered under the knocking of the first scattering rod (64) and the second scattering rod (68) rotating in the opposite direction, and then fall into the inside of the screening box (82) through the guide hopper (81); Step four: while the rotating drum (5) is rotating, one end of the C-shaped rod (843) can be squeezed by the eccentric ring (841), so that the clamping block (844) can pull or push the screening box (82) under the elastic force of the second compression spring (845), so that the screening box (82) can reciprocate in the horizontal direction, so as to screen the feed screened by the primary filter plate (3) and the scattered feed again, and at the same time, the drying lamp (12) is started to dry the feed, remove the larger impurities, and make the dried feed fall into the inside of the feed box (13).
