Description

Technical Field

[0001] The invention relates to the field of feed mixing, and more specifically to a screening and mixing device for experimental monkey feed. Background Art

[0002] Experimental monkeys generally use crab-eating macaques, because the genes of crab-eating macaques are highly similar to human genes and their physiological characteristics are similar, so using crab-eating macaques as experimental monkeys can provide more realistic experimental results. When preparing crab-eating macaque feed, because of their demand for unsaturated fatty acids and other minerals, it is necessary to add some animal oil or vegetable oil during the preparation to provide the nutrients needed for their growth. The main raw materials of the feed are usually corn, wheat, barley, and oats ground into powder. Because of the needs of crab-eating macaques, raw materials such as fish meal and meat and bone meal need to be added. Liquid raw materials need to be added with fish oil or other animal and vegetable oils, and a certain amount of additives are added to supplement vitamins, and some minerals also need to be added.

[0003] The above materials all need to be pre-screened before mixing, but the powders of different materials have different diameters, and the screening standards for liquids and solids are different. The screening conditions for viscous liquids and non-viscous liquids are also different. Classification and screening should be strictly carried out before mixing to prevent deteriorated substances such as agglomeration and precipitation from being mixed into feed. However, the traditional screening method is to use different screening mechanisms to screen different materials when screening, and then mix them after screening. This not only increases costs, but also causes a lot of raw materials to be wasted when multiple screening devices are used for long-term processing because raw materials are attached to the screening device during screening.

[0004] In view of this, the present invention improves and optimizes the mixing and screening device in the prior art and develops a screening and mixing device for experimental monkey feed. Summary of the invention

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. This solution can change the rotation speed of the first conical cylinder and the second conical cylinder by controlling the working part, thereby changing the overlap of the first sieve hole and the second sieve hole, and then changing the size of the sieve hole, so as to change the state of the screening component according to the different materials, so as to better pre-treat the materials, without using multiple screening devices, because the screening component is always used for screening, so there is no waste of raw materials, and materials of various diameters and states can be pre-treated and screened.

[0018] 2. This solution sets a screening component. Since the first conical cylinder and the second conical cylinder are conical in shape, the screening speed can be further increased. When the first conical cylinder and the second conical cylinder rotate, air flow will be formed outside them, so that the ejected materials cannot enter the interior of the screening component again, so that the materials can only be screened in one direction. While increasing the screening rate, it can also prevent the materials from flying. If the material is transformed from solid to liquid, the liquid can be evenly dispersed throughout the mixing shell to prevent the liquid from accumulating together and causing the material to agglomerate.

[0019] 3. The device is provided with a push rod so that the device can be adjusted during operation without stopping the machine. The size of the sieve hole can be controlled by pressing it, and the reading of the sieve hole change can be observed in real time through the dial, making the device more convenient to use.

[0020] 4. This solution can prevent impurities from clogging the sieve holes and reducing the screening efficiency by setting a cleaning component. It can automatically adapt to the shape of the second conical cylinder so that it can always fit the surface and clean the surface, ensuring that the cleaning component can clean all parts of the second conical cylinder with high cleanliness. When the material is added to the inside of the screening component, the reciprocating movement of the cleaning component can also pre-mix and pre-stir the material.

[0021] 5. This solution can comb off the impurities attached to the bristles by setting an L-shaped cleaning rod and store them inside the L-shaped cleaning rod. The material taking door can be slid open to remove the impurities on the L-shaped cleaning rod. It can be easily removed even during work, and the bristles can be cleaned to prevent the impurities from being repeatedly brushed off.

[0022] 6. In this scheme, by setting a screening component, when the device needs to be cleaned, it is only necessary to control the working component to completely stagger the first sieve hole and the second sieve hole, and then inject water into the interior of the screening component through the feed hopper. After waiting for a certain amount of clean water to be contained in the screening component, the working component is controlled to open the first sieve hole and the second sieve hole. As the screening component rotates, the water flow can be rotated and thrown out, so that the clean water flushes all parts of the interior of the mixing shell, and then cleans all parts of the interior of the mixing shell, thereby improving the cleanliness level and preventing raw material contamination caused by insufficient cleaning.

[0027] Experimental monkeys generally use crab-eating macaques, because the genes of crab-eating macaques are highly similar to human genes and their physiological characteristics are similar, so using crab-eating macaques as experimental monkeys can provide more realistic experimental results. When preparing crab-eating macaque feed, because of their demand for unsaturated fatty acids and other minerals, it is necessary to add some animal oil or vegetable oil during the preparation to provide the nutrients needed for their growth. The main raw materials of the feed are usually corn, wheat, barley, and oats ground into powder. Because of the needs of crab-eating macaques, raw materials such as fish meal and meat and bone meal need to be added. Liquid raw materials need to be added with fish oil or other animal and vegetable oils, and a certain amount of additives are added to supplement vitamins, and some minerals also need to be added.

[0028] The above materials all need to be pre-screened before mixing, but the powders of different materials have different diameters, and the screening standards for liquids and solids are different. The screening conditions for viscous liquids and non-viscous liquids are also different. They should be strictly classified and screened before mixing to prevent deteriorated substances such as agglomeration and precipitation from being mixed into feed. However, traditionally, different screening mechanisms are often used to screen different materials, and then they are mixed after screening. This not only increases costs, but also causes a lot of raw material waste due to the raw materials attached to the screening device during screening, and the long-term processing of multiple screening devices.

[0029] Furthermore, the present device is provided with a screening component 3. When it is actually used, the raw materials required for mixing are first added to the inside of the screening component 3, and then the motor 6 is started. The motor 6 drives the transmission wheel 61 to work, and the transmission wheel 61 drives the working component 4 to work. When the working component 4 works, it can drive the first conical cylinder 31 and the second conical cylinder 32 to rotate synchronously. Because the first conical cylinder 31 and the second conical cylinder 32 are designed from small to large, when the material enters, it can be quickly screened by the first sieve hole 33 and the second sieve hole 34 as it rotates. Designing the first conical cylinder 31 and the second conical cylinder 32 to be conical can improve the screening efficiency. By controlling the working component 4, the rotation speed of the first conical cylinder 31 and the second conical cylinder 32 can be changed, so that the overlap of the first sieve hole 33 and the second sieve hole 34 is changed, and then the size of the sieve hole is changed, so that the state of the screening component 3 can be changed according to the different materials, and then the material can be better pre-processed without using multiple screening devices. Because the screening component 3 is always used for screening, there is no waste of raw materials, and materials of various diameters and states can be pre-processed and screened.

[0030] Traditionally, in order to improve the screening efficiency, most people tilt the screen and then use a vibration device to vibrate the screen to improve the screening efficiency. However, when screening powdered materials, the powder will be lifted up and dispersed in the air, which not only causes a waste of raw materials, but also pollutes the working environment and causes harm to workers who work for a long time. The present device abandons the traditional screen-type screening and uses the first conical cylinder 31 and the second conical cylinder 32 to cooperate with each other for rotation screening. When the screening component 3 rotates, the material inside it can be thrown out. Because the first conical cylinder 31 and the second conical cylinder 32 are conical in shape, the screening speed can be further increased. When the first conical cylinder 31 and the second conical cylinder 32 rotate, air flow will be formed outside them, which makes it impossible for the thrown material to enter the interior of the screening component 3 again, so that the material can only be screened in one direction. While increasing the screening rate, it can also prevent the material from flying. If the material is converted from solid to liquid, the liquid can be evenly dispersed throughout the mixing shell 2 to prevent the liquid from accumulating together and causing the material to agglomerate.

[0031] A protective shell 21 is fixedly installed at a position corresponding to the working part 4 on one side of the outer surface of the mixing shell 2. The protective shell 21 is sleeved on the outside of the working part 4. The protective shell 21 is located at the end with a larger diameter of the first conical cylinder 31 and the second conical cylinder 32. A feed hopper 22 is fixedly installed on the side of the outer surface of the mixing shell 2 away from the protective shell 21. A material taking door 23 is provided below the feed hopper 22. The material taking door 23 is slidably installed on the outer surface of the mixing shell 2. A discharge pipe 24 is provided below the discharge door 23. The discharge pipe 24 is fixedly installed on the mixing shell 2. A valve 241 is installed on the discharge pipe 24. The discharge pipe 24 is connected to the lower end of the inner part of the mixing shell 2.

[0032] When in use, raw materials are added to the interior of the screening component 3 through the feed hopper 22, and the screened and mixed raw materials will be output to the device through the discharge pipe 24. When in use, a lot of impurities will be screened out from the interior of the screening component 3. If they are not cleaned in time, the screen holes will be blocked, resulting in reduced screening efficiency. Therefore, when the working component 4 is working, it will drive the cleaning component 5 to work. The cleaning component 5 can automatically adapt to the shape of the second conical cylinder 32, and reciprocate along the interior of the second conical cylinder 32 to clean the impurities inside the second conical cylinder 32. The screened raw materials will fall into the bottom of the mixing shell 2, and the motor 6 drives the transmission wheel 61 and the stirring rod 62 to rotate, thereby mixing the materials. Opening the valve 241 can discharge the mixed materials from the device through the discharge pipe 24, and the material taking door 23 is used to remove impurities.

[0033] The working component 4 includes a rotating cylinder 41, and a rack belt is used to transmit the power between the transmission wheel 61 and the rotating cylinder 41. The rotating cylinder 41 is fixedly installed at the end of the first conical cylinder 31, and a first gear ring 42 is fixedly installed at the inner ring of the rotating cylinder 41. A sun gear 43 is arranged inside the rotating cylinder 41, and the sun gear 43 is fixedly installed at the end of the second conical cylinder 32. A support cover plate 411 is fixedly installed on the side of the rotating cylinder 41 away from the mixing shell 2, and a matching sleeve 44 is arranged between the support cover plate 411 and the sun gear 43. A plurality of evenly distributed connecting rods 441 are fixedly installed on the outer ring of the matching sleeve 44, and a sliding rod 442 is rotatably installed at one end of the connecting rod 441 away from the matching sleeve 44, and a planetary gear 443 is provided on the outer sliding card of the sliding rod 442. A dial 45 is fixedly installed in the middle of the side of the support cover plate 411 away from the sun gear 43, and a protective shell A fixing frame 46 is fixedly installed at the position corresponding to the body 21 and the dial 45, a pointer 211 is fixedly installed in the middle of the side of the protective shell 21 away from the mixing shell 2, a push rod 47 is slidably clamped in the middle of the fixing frame 46, a return spring 48 is fixedly connected between the push rod 47 and the fixing frame 46, one end of the push rod 47 passes through the dial 45 and is rotatably clamped in the inside of the matching sleeve 44, a clamping block 431 is fixedly installed in the middle of one side of the sun gear 43 close to the supporting cover plate 411, a plurality of second clamping grooves 471 corresponding to the clamping block 431 are provided at one end of the push rod 47 close to the sun gear 43, a matching cylinder 451 is fixedly installed on the side of the dial 45 close to the supporting cover plate 411, a protrusion 444 is fixedly installed on the inner ring of the matching sleeve 44, and a plurality of first clamping grooves 452 corresponding to the protrusion 444 are provided at the position of the matching cylinder 451 close to the matching sleeve 44.

[0034] When the motor 6 is working, it will drive the transmission wheel 61 to rotate, and the rack belt transmission wheel 61 can drive the rotating cylinder 41 to rotate. At this time, under the action of the reset spring 48, the matching sleeve 44 is pulled, causing the protrusion 444 to be stuck in the first slot 452, and then the rotating cylinder 41 rotates to drive the support cover plate 411 to rotate, and the support cover plate 411 drives the matching sleeve 44 and the connecting rod 441, the sliding rod 442, and the planetary gear 443 to rotate. At this time, the rotating cylinder 41, the first gear ring 42, and the sun gear 43 revolve synchronously, and then the sun gear 43 is also driven to rotate under the action of the planetary gear 443. At this time, the first conical cylinder 31 and the second conical cylinder 32 are driven to rotate synchronously. When the size of the sieve hole needs to be changed, only the push rod 4 needs to be pressed. 7. At this time, the reset spring 48 is compressed, and the block 431 blocks the second slot 471. When the push rod 47 is pushed, the matching sleeve 44 is also driven to move so that the protrusion 444 slides out from the first slot 452, and then the dial 45 cannot drive the matching sleeve 44 to rotate. At this time, the sun gear 43 is stuck by the push rod 47 and cannot rotate. The rotating cylinder 41 is driven to rotate continuously, and the planetary gear 443 rotates along the outer ring of the first gear ring 42 and the sun gear 43, which leads to a speed difference between the sun gear 43 and the rotating cylinder 41, which leads to the first sieve hole 33 and the second sieve hole 34 being staggered, thereby changing the size of the sieve hole. In this process, the size of the sieve hole change can be judged by observing the change in the reading of the pointer 211 on the dial 45.

[0035] Therefore, the device is provided with a push rod 47 so that the device can be adjusted during operation without stopping the machine. The size of the sieve hole can be controlled by pressing, and the reading of the sieve hole change can be observed in real time through the dial 45, making the device more convenient to use.

[0036] The cleaning component 5 includes a reciprocating sleeve 51, a plurality of evenly distributed spring telescopic rods 52 are fixedly installed on the outer ring of the reciprocating sleeve 51, a support plate 53 is fixedly installed on one end of the spring telescopic rod 52 away from the reciprocating sleeve 51, a plurality of evenly distributed bristles 54 are fixedly installed on the side of the support plate 53 away from the spring telescopic rod 52, rollers 55 are rotatably installed on both ends of the side of the support plate 53 away from the spring telescopic rod 52, a slide groove 56 is provided on both sides of the reciprocating sleeve 51, a reciprocating screw 26 is rotatably installed inside the mixing shell 2, the reciprocating screw 26 is fixedly installed in the middle of the sun gear 43, the reciprocating screw 26 is located at the inner center position of the screening component 3, guide rods 27 are provided on both sides of the reciprocating screw 26, the guide rods 27 are fixedly installed inside the mixing shell 2, the reciprocating screw 26 is cooperated and clamped inside the reciprocating sleeve 51, the guide rod 27 is slidably clamped inside the slide groove 56, and a plurality of evenly distributed L-shaped cleaning rods 25 are installed at the position inside the mixing shell 2 corresponding to the cleaning component 5.

[0037] When the sun gear 43 rotates, it drives the reciprocating screw 26 to rotate. When the reciprocating screw 26 rotates, it can drive the reciprocating sleeve 51 to move back and forth along its surface. The guide rod 27 is used to limit the reciprocating sleeve 51. When the reciprocating sleeve 51 moves, it drives the spring telescopic rod 52 to move. Because the roller 55 is a universal wheel, when the reciprocating sleeve 51 moves, the support plate 53 can always slide against the surface of the second conical tube 32 under the push of the spring telescopic rod 52, and then when the inner diameter of the second conical tube 32 changes, the spring telescopic rod 52 can also change accordingly, so that the bristles 54 always fit the second conical tube The inner surface of 32, because the cleaning component 5 is restricted by the guide rod 27 as a whole and cannot rotate, and the second conical cylinder 32 rotates continuously, the bristles 54 can not only clean the second conical cylinder 32 horizontally, but also perform circular rotation cleaning on the inside of the second conical cylinder 32 to prevent impurities from blocking the sieve holes and causing a decrease in screening efficiency. It can automatically adapt to the shape of the second conical cylinder 32 so that it can always fit the surface and clean the surface, ensuring that the cleaning component 5 can clean all parts of the second conical cylinder 32 with high cleanliness. When the material is added to the inside of the screening component 3, the reciprocating movement of the cleaning component 5 can also pre-mix and pre-stir the material.

[0038] When the cleaning component 5 moves to the position of the L-shaped cleaning rod 25, because the L-shaped cleaning rod 25 is L-shaped, the bristles 54 will be moved by the L-shaped cleaning rod 25 as the cleaning component 5 moves to produce a comb-like effect. The L-shaped cleaning rod 25 can comb off the impurities attached to the bristles 54 and store them on the L-shaped cleaning rod 25. The sliding material collection door 23 is opened, and then the impurities on the L-shaped cleaning rod 25 can be taken out. Even during work, it can be easily taken out, and the bristles 54 can also be cleaned to prevent the impurities from being repeatedly brushed off.

[0039] When the cleaning device is needed, it is only necessary to control the working component 4 so that the first sieve hole 33 and the second sieve hole 34 are completely staggered, and then inject water into the interior of the screening component 3 through the feed hopper 22. After waiting for a certain amount of clean water to be contained in the screening component 3, the working component 4 is controlled to open the first sieve hole 33 and the second sieve hole 34. As the screening component 3 rotates, the water flow can be rotated and thrown out, so that the clean water flushes all parts of the interior of the mixing shell 2, and then cleans all parts of the interior of the mixing shell 2, thereby improving the cleanliness level and preventing raw material contamination caused by insufficient cleaning.

[0040] Working principle: In actual use, first add the raw materials required for mixing into the interior of the screening component 3, and then start the motor 6. The motor 6 drives the working component 4 to work. When the working component 4 works, it can drive the first conical cylinder 31 and the second conical cylinder 32 to rotate synchronously. Because the first conical cylinder 31 and the second conical cylinder 32 are designed from small to large, when the material enters, it can be quickly screened by the first sieve hole 33 and the second sieve hole 34 as it rotates. By controlling the working component 4, the rotation speed of the first conical cylinder 31 and the second conical cylinder 32 can be changed, so that the overlap of the first sieve hole 33 and the second sieve hole 34 is changed, thereby changing the size of the sieve hole.

[0041] When the working component 4 is working, it can drive the reciprocating screw 26 to work. When the reciprocating screw 26 is working, it will drive the cleaning component 5 to slide back and forth along the inside of the second conical cylinder 32. During this process, the cleaning component 5 can automatically adapt to the internal shape of the second conical cylinder 32, thereby providing a better cleaning effect. As the cleaning component 5 moves, the L-shaped cleaning rod 25 can also comb out the impurities cleaned out by the cleaning component 5. The screened material is mixed by the stirring rod 62 and discharged from the device along the discharge pipe 24.

[0042] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
