Description

Technical Field

[0001] The invention relates to the technical field of animal feed production, in particular to a preparation method and application of a composition for preventing rumen acidosis. Background Art

[0002] Rumen acidosis is an acid metabolic disease caused by the accumulation of lactic acid and volatile fatty acids (VFA) in the rumen of cattle after eating a large amount of grains or other carbohydrate-rich feeds. In order to prevent rumen acidosis, special attention should be paid to the composition, proportion and processing method of the feed when preparing the feed to ensure that the feed ingested by the cattle can maintain the acid-base balance of the rumen and promote the normal functioning of the digestive function. The following is a method for preparing a "feed to prevent rumen acidosis".

[0003] The feed prepared in the prior art will greatly affect the probability of rumen acidosis in cattle. In the conventional scheme, the fermentation rate of the concentrate in the rumen is controlled by avoiding excessive grinding of the feed during processing, especially energy feed such as corn, to avoid excessive increase in acidity. However, the fineness of feed required by adult fattening cattle and calves is different, so a single preparation and grinding equipment cannot obtain feed of different specifications at the same time, and the fineness of the feed prepared later will change due to blockage of the sieve during the preparation process, and it is impossible to ensure that the prepared feed composition meets the expected requirements, and the final effect of preventing rumen acidosis will also be reduced. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a method for preparing and using a composition for preventing rumen acidosis, so as to solve the problems raised in the above-mentioned background technology. The present invention can simultaneously prepare two kinds of fine-specification feeds through a single preparation device, and provides two cleaning schemes for the screen, thereby improving the cleaning efficiency.

[0005] In order to achieve the above object, the present invention is implemented by the following technical scheme: a method for preparing a composition for preventing rumen acidosis, comprising the following steps:

[0006] Step 1: Choose high-quality hay, silage, and corn straw as roughage, and corn, soybean meal, and wheat bran as concentrate feed;

[0007] Step 2: Mix the roughage and concentrated feed in a ratio of 6:4;

[0008] Step 3: The mixed feed is crushed, and two feeds of different sizes are prepared at the same time by means of a screen laid inside the crushing preparation equipment, and the two feeds of different fineness are respectively discharged into two discharge boxes below through the fine screening area and the coarse screening area staggered on the screen;

[0009] Step 4: After the sieving is completed for a long time, the screen is moved and replaced by the push mechanism on the top, and the inner side of the used screen is cleaned by high pressure with the help of the crushing component inside the crushing box during the replacement process, and a buffer is added to the mixed feed. The buffer uses alkaline earth metal compounds such as sodium bicarbonate or magnesium oxide;

[0010] Step 5: Add trace elements and vitamin additives to the feed;

[0011] Step 6: The prepared feed should be sealed and stored in a dry, ventilated, rodent-proof and insect-proof place.

[0012] Furthermore, in the step 2, the ratio of roughage to concentrated feed is 7:3, wherein the roughage is pre-cut, the corn stalks in the roughage are cut into 3-5 cm, and the hay is cut into 8-10 cm; in the step 5, the vitamins include fat-soluble vitamins and water-soluble vitamins, wherein the water-soluble vitamins include B vitamins and vitamin C, and the proportion of baking soda buffer in the prepared feed composition is 0.7% to 1.5%.

[0013] Furthermore, in the step three, the crushing assembly is started when the feed is crushed. After the crushing assembly rotates, the first extension plate and the second extension plate at both ends are driven to rotate synchronously through the second driving shaft. Multiple independent blades at the end of the first extension plate pass through the material blocking mechanism part at the bottom of the crushing box, completing a single process of cutting the feed accumulated below, and controlling the crushing assembly to rotate repeatedly. In the process of continuous cutting, the feed that meets the size accuracy requirements falls downward from the screen surface below.

[0014] Furthermore, while the independent blade is driven to rotate by the second driving shaft, the pushing mechanism on the other side is also driven to rotate synchronously. After the pushing mechanism rotates to the bottom, it presses on the blocking column in the blocking mechanism. The blocking column rotates around the supporting shaft at the end until the blocking column is embedded in the hidden groove as a whole. At this time, the scraper pushes the cut feed on one side of the blocking column toward the rear end of the blocking column.

[0015] Furthermore, the feed moves along the fine screening area and the coarse screening area below the screen respectively, with the help of the fine screening area firstly discharging the fine particles of the pushed feed, and then the large-sized particles in the remaining feed are screened out through the coarse screening area, and the remaining feed rotates to a higher place with the pushing mechanism, and then falls to one side of the bottom blocking mechanism to repeat the cutting process.

[0016] Furthermore, during the rotation of the pushing mechanism, a high-pressure airflow is continuously delivered toward the interior of the second drive shaft along the inflation pipe through an external air pump. The high-pressure airflow enters the interior of the cleaning sleeve along the interior of the second extension plate, and is blown toward the outer surface of the screen through the conical blowing holes at the end of the cleaning sleeve, thereby achieving a recoil cleaning treatment on the inside of the screen and assisting in accelerating the blowing of the feed into the corresponding discharge box.

[0017] Furthermore, the top of the screen passes outward from the notch parts on both sides of the crushing box, while the bottom of the screen goes around the bottom of the convex column below. Therefore, after a long period of crushing, the first motor on the top is started, and with the help of the first drive shaft and gear, it contacts the toothed belt at the edge of the screen to control the entire screen to rotate. The screen at the bottom of the crushing box can be moved to the top area, and the new screen part on the top can be replaced to the bottom for screening.

[0018] Furthermore, while the screen is pulled to the outside by the gear on the top, the crushing assembly on the inside is started synchronously. After the crushing assembly rotates to align the conical air hole with the conical air inlet hole, the internal air flow is finally ejected from the outside of the conical air inlet hole, and the screen area moving on the arc top is recoil cleaned with a higher pressure.

[0019] Furthermore, when the screen is driven to move by the first motor and gear at the top, the bottom of the screen continues to move under the convex column at the bottom of the crushing box, and the edge of the screen and the toothed belt part at the edge pass through the notches on both sides of the crushing box and are embedded in the fitting groove.

[0020] An application of the composition produced by the preparation method, wherein the composition is used for feeding ruminants such as cattle and sheep to prevent rumen acidosis.

[0021] Beneficial effects of the present invention:

[0022] 1. The method for preparing a composition for preventing rumen acidosis can prepare an effective "feed for preventing rumen acidosis" through reasonable raw material selection and ratio, scientific feed processing and modulation, and standardized storage and feeding management, and can control the fermentation rate of concentrate in the rumen to avoid excessive increase in acidity, and can also prepare a feed composition suitable for calves or adult fattening cattle.

[0023] 2. In the preparation method of the composition for preventing rumen acidosis, the preparation and crushing equipment used in the crushing process, after the crushing component completes a single shearing and crushing, the scraper on the other side can be used to pass the crushed feed at the bottom along the fine screening area and the coarse screening area on the screen in sequence, thereby screening out two feeds of different sizes at the same time, and finally preparing a feed composition suitable for calves or adult fattening cattle at the same time, and the surface of the screen can also be cleaned in the process.

[0024] 3. The preparation method of the composition for preventing rumen acidosis can quickly switch the used screen inside and outside during the crushing process, and then move the screen part after use to the outside, and during the movement, through the continuous rotation of the outer driving device and the inner crushing component, it can provide more targeted recoil cleaning treatment, so that the entire screen can be cyclically replaced for a long time, extending the service life of the equipment and the cycle of manual maintenance.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] See also Figures 1 to 8 The present invention provides the following technical solution: a method for preparing a composition for preventing rumen acidosis, comprising the following steps:

[0036] Step 1: Choose high-quality hay, silage, and corn straw as roughage, and corn, soybean meal, and wheat bran as concentrate feed;

[0037] Step 2: Roughage and concentrate are mixed in a ratio of 6:4; the ratio of roughage and concentrate is also 7:3, wherein the roughage is pre-cut, the corn stalks in the roughage are cut into 3-5 cm, and the hay is cut into 8-10 cm;

[0038] Step 3: The mixed feed is crushed, and two feeds of different sizes are prepared at the same time by means of the screen 10 laid inside the crushing preparation equipment, and the two feeds of different fineness are respectively discharged into the two discharge boxes below through the fine screening area and the coarse screening area 31 staggeredly distributed on the screen 10;

[0039] Step 4: After the sieving is completed for a long time, the screen 10 is transferred and replaced by the pushing mechanism at the top, and during the replacement process, the inner side of the used screen 10 is subjected to high-pressure cleaning by means of the crushing assembly 16 inside the crushing box 1, and a buffer is added to the mixed feed, and the buffer uses an alkaline earth metal compound such as sodium bicarbonate or magnesium oxide;

[0040] Step 5, adding trace elements and vitamin additives to the feed, wherein the vitamins include fat-soluble vitamins and water-soluble vitamins, wherein the water-soluble vitamins include B vitamins and vitamin C, and the proportion of baking soda buffer in the prepared feed composition is 0.7% to 1.5%;

[0041] Step 6: The prepared feed should be sealed and stored in a dry, ventilated, rodent-proof and insect-proof place.

[0042] This preparation method can prepare effective "feed for preventing rumen acidosis" through reasonable raw material selection and ratio, scientific feed processing and modulation, and standardized storage and feeding management, can control the fermentation rate of concentrate in the rumen, avoid excessive increase in acidity, and simultaneously prepare a feed composition suitable for calves or adult fattening cattle.

[0043] In this embodiment, a crushing preparation device is used in step 3, and the crushing preparation device includes a crushing box 1 and a crushing assembly 16 inside. The top of the crushing box 1 is integrally formed with an arc top 2, and the front and rear ends of the crushing box 1 are welded with side plates 3. Notches 6 are opened at both ends of the arc top 2. The bottom of the crushing box 1 is welded with a first discharge box 5 and a second discharge box 4. The interior of the first discharge box 5 is used to discharge coarsely crushed feed, and the interior of the second discharge box 4 is used to discharge finely crushed feed. A support plate 7 is integrally formed on the side of the second discharge box 4. The surface of the support plate 7 is protected from an air pump 8, and one end of the air pump 8 is connected to an inflation pipe 9. The crushing assembly 16 includes a second motor 19 and a first pneumatic column. The second motor 19 is screwed to the middle of the surface of the side plate 3. The output end of the second motor 19 is inserted with a second drive shaft 20. The first extension plate 22 and the second extension plate 25 are welded to the sides of both ends of the second drive shaft 20. A support rod 23 is welded to the inner side of the end of the first extension plate 22, and a plurality of independent blades 24 are sleeved on the surface of the support rod 23.

[0044] When the feed is crushed, the crushing assembly 16 is started. After the crushing assembly 16 rotates, the first extension plate 22 and the second extension plate 25 at both ends are driven to rotate synchronously through the second drive shaft 20. The multiple independent blades 24 at the end of the first extension plate 22 pass through the blocking mechanism 18 at the bottom of the crushing box 1 to complete the process of cutting the feed accumulated below in a single time. The crushing assembly 16 is controlled to rotate repeatedly, and the feed that meets the dimensional accuracy requirements falls downward from the surface of the screen 10 below during the continuous cutting process. While the independent blades 24 are driven to rotate by the second drive shaft 20, the pusher mechanism 17 on the other side is driven to rotate synchronously. After the pusher mechanism 17 rotates to the bottom, it presses on the blocking column 36 in the blocking mechanism 18. The blocking column 36 rotates around the support shaft 37 at the end until the blocking column 36 is completely embedded in the hidden groove 34. At this time, the scraper 26 pushes the cut feed on one side of the blocking column 36 toward the rear end of the blocking column 36. The feed moves along the fine screening area and the coarse screening area 31 below the screen 10, respectively. The fine particles of the pushed feed are discharged by the fine screening area, and then the large-sized particles in the remaining feed are screened out by the coarse screening area 31. After the remaining feed rotates to a high place with the pushing mechanism 17, it falls back to one side of the bottom blocking mechanism 18 to repeat the cutting process.

[0045] During the crushing process of the preparation and crushing equipment used, after each single shearing and crushing is completed by the crushing component 16, the scraper 26 on the other side can be used to slide the crushed feed at the bottom along the fine screening area and the coarse screening area 31 on the screen 10 in sequence, thereby screening out two feeds of different sizes at the same time, and finally preparing a feed composition suitable for calves or adult fattening cattle at the same time, and the surface of the screen 10 can also be cleaned in the process.

[0046] In this embodiment, the side of the crushing assembly 16 is connected to the pushing mechanism 17 through the second extension plate 25, and a scraper 26 and a cleaning sleeve 27 are provided at the end of the pushing mechanism 17. A docking bearing 21 is provided at the end of the second driving shaft 20, and the docking bearing 21 is connected to the external inflation pipe 9. The interior of the second extension plate 25 is a hollow structure, and the interior of the second extension plate 25 is connected to the cleaning sleeve 27 at the end. A conical blowing hole 28 is provided at the bottom of the cleaning sleeve 27, and the conical blowing hole 28 and the scraper 26 are pressed against the inner wall of the crushing box 1. A plurality of discharge mechanisms are inserted at the bottom of the crushing box 1, and the discharge mechanisms include a hidden groove 34 and a blocking column 36. A support shaft 37 is integrally formed at one end of the blocking column 36, and a movable baffle 38 is integrally formed at the bottom of the rear end of the blocking column 36. An arc-top baffle is integrally formed at the top of the rear end of the hidden groove 34. An arc-shaped spring 39 is welded to the bottom of the blocking column 36, and the bottom of the spring 39 rests against the bottom end of the hidden groove 34.

[0047] During the rotation of the push mechanism 17, the external air pump 8 continuously delivers high-pressure airflow along the inflation pipe 9 toward the inside of the second drive shaft 20, and the high-pressure airflow enters the inside of the cleaning sleeve 27 along the inside of the second extension plate 25, and blows out toward the surface of the outer screen 10 through the conical blowing hole 28 at the end of the cleaning sleeve 27, so as to achieve the recoil cleaning treatment of the inner side of the screen 10, and assist the feed to be blown into the corresponding discharge box at an accelerated speed. The top of the screen 10 passes outward from the notch 6 on both sides of the crushing box 1, and the bottom of the screen 10 bypasses the bottom of the convex column 33 below. Therefore, after a long period of crushing, the first motor 13 at the top is started, and the first drive shaft 14 and the gear 15 are used to contact the toothed belt 11 at the edge of the screen 10 to control the entire screen 10 to rotate, so that the screen 10 at the bottom of the crushing box 1 can be moved to the top area, and the new screen 10 at the top is replaced to the bottom for screening.

[0048] In this embodiment, two end plates 12 are installed on the top of the crushing box 1, and a first motor 13 is screwed on the surface of one of the end plates 12, and a first drive shaft 14 is inserted on the output end of the first motor 13, and a gear 15 is keyed on the surface of the first drive shaft 14. The surface of the screen 10 is alternately provided with fine screening areas and coarse screening areas 31, and a toothed belt 11 is attached to the side of the screen 10. The gear 15 is at the top of the crushing box 1, and the gear 15 is meshed with the toothed belt 11. A conical air inlet hole 29 is opened on the surface of the arc-shaped top 2. After the pushing mechanism 17 rotates with the second drive shaft 20, the conical blowing hole 28 will be connected to the inner side of the conical air inlet hole 29. When the screen 10 moves along the surface of the arc-shaped top 2, the air pump 8 will blow the airflow out from the inner side of the screen 10 in sequence along the second extension plate 25, the cleaning sleeve 27, the arc-shaped blowing hole, and the arc-shaped air inlet hole.

[0049] In the process of pulling the screen 10 to move to the outside by means of the gear 15 at the top, the crushing assembly 16 at the inside is started synchronously. After the crushing assembly 16 rotates to align the conical blowing hole 28 with the conical air inlet hole 29, the internal airflow finally sprays out from the outside of the conical air inlet hole 29, and the area of ​​the screen 10 moving on the arc top 2 is recoil-cleaned with a higher pressure. In the process of driving the screen 10 to move by the first motor 13 and the gear 15 at the top, the bottom of the screen 10 continues to move under the protrusion 33 at the bottom of the crushing box 1, and the edge of the screen 10 and the toothed belt 11 at the edge penetrate the notch 6 on both sides of the crushing box 1 and are embedded in the fitting groove 32. During the crushing process, the used screen 10 can be quickly switched inside and outside, and the screen 10 part after use can be moved to the outside. During the movement, the outer driving device and the inner crushing assembly 16 continue to rotate, which can provide more targeted recoil cleaning treatment, so that the entire screen 10 can be circulated and replaced for a long time, extending the service life of the equipment and the cycle of manual maintenance.

[0050] This embodiment also provides an application of the composition produced by the above preparation method, wherein the composition is used for feeding ruminants such as cattle and sheep and preventing rumen acidosis.
