Description

Technical Field

[0001] The present application relates to the technical field of laying hen feed, and in particular to a premixed granular feed for improving the egg production of laying hens and a preparation device and method thereof. Background Art

[0002] Layer farming is an important part of agriculture. The use of premixed pellet feed significantly improves the egg production rate and egg quality of laying hens, thereby increasing the economic benefits of farmers. With the continuous growth of market demand, increasing the egg production of laying hens has become the focus of farmers; reasonable feed formula and efficient feed preparation equipment are the key factors to achieve this goal.

[0003] At present, in order to increase the egg production of laying hens, the premixed pellet feed commonly used in the market mainly includes a mixture of various nutrients, such as corn flour, bran, soybean meal, etc. These ingredients are usually made into pellet feed through simple physical mixing or primary processing technology. Common preparation methods include blending in a mixer as a pretreatment step, followed by pelleting through an extruder or roller machine. In addition, some farmers will add a small amount of additives to enhance the effect of the feed. Although these methods have improved the quality of the feed to a certain extent, there are still some shortcomings.

[0004] However, the existing premixed pellet feed and its preparation method have some obvious defects. First, the traditional mixing method is difficult to ensure the uniform distribution of various ingredients, resulting in unstable nutritional value of the feed. Secondly, the lack of effective molding and packaging technology in the pelleting process makes the feed easy to break, affecting the shape and appearance of the feed. On the other hand, during the storage of the feed, the traditional pellet feed easily absorbs moisture in the air, causing the feed to deteriorate. More importantly, the traditional preparation equipment is inefficient during operation and cannot meet the needs of large-scale production. It also has a greater impact on the environment.

[0020] On the other hand, the present application provides a device for preparing a premixed granular feed for increasing the egg production of laying hens.

[0021] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A method for preparing a premixed pellet feed for increasing egg production of laying hens comprises: Bracket 1; A material storage device mounted on the support 1 for storing materials: A pellet forming device is installed on the bracket 1, and the pellet forming device includes a bottom mold assembly 2, a feeding assembly 3 and a shell pressing assembly 6. The bottom mold assembly 2 includes a roller 21, and the roller 21 is coaxially rotatably connected to the bracket 1. In the present application, the roller 21 is horizontally arranged, and a plurality of mounting holes 211 are provided on the peripheral wall of the roller 21 in a direction perpendicular to the axis of the roller 21. The plurality of mounting holes 211 arranged along the axis of the roller 21 are in a row, and the roller 21 is provided with a plurality of rows of mounting holes 211 along its circumference; a bottom mold column 22 is slidably connected in each mounting hole 211, and a bottom mold groove 221 is provided at one end of the bottom mold column 22 away from the axis of the roller 21; Each mounting hole 211 is provided with a first driving assembly 4 for driving the bottom mold column 22 to slide; The feeding assembly 3 comprises a mounting plate 31, on which a plurality of packing columns 32 are arranged in a straight line direction, and the mounting plate 31 is slidably connected to the bracket 1 to drive the plurality of packing columns 32 on the mounting plate 31 to be inserted one by one into a row of mounting holes 211; A hemispherical filling head 33 is embedded at one end of the filling column 32 close to the axis of the roller 21, and the filling head 33 is rotatably connected to the filling column 32, and a driving rod 34 is slidably connected to the filling column 32 to drive the filling head 33 to rotate; A first feed channel 321 communicating with the material storage device is provided inside the packing column 32, and a second feed channel 331 is provided through the packing head 33; When the flat end of the packing head 33 is flush with the end of the packing column 32 close to the axis of the roller 21, the second feed channel 331 is not connected to the inner cavity of the mounting hole 211. When the packing head 33 rotates a certain angle, one end of the second feed channel 331 is connected to the first feed channel 321, and the other end is connected to the inner cavity of the mounting hole 211. A first starting assembly 5 is disposed in each mounting hole 211, and the first starting assembly 5 is used to control the movement of the push rod 34; The compression shell assembly 6 includes a hemispherical pressure head 61; In the rotating direction of the roller 21, a shell pressing station, a filling station, a pill combining station and a pill discharging station are sequentially arranged. The feeding assembly 3 is provided with two groups, one at the shell pressing station and the other at the filling station. In the shell pressing station, each filling head 33 is provided with a pressing head 61, and the filling head 33 and the pressing head 61 form a complete sphere. In the present application, since the shell material contains edible oil, the shell material mixture is viscous, and the core material is a powder feed. In order to facilitate the delivery of the shell material and the core material, the shell pressing station in the present application is located above the axis of the roller 21, and the filling station is located directly above the axis of the roller 21. There are two pill-forming devices, which are symmetrically arranged. The two rollers 21 rotate from top to bottom close to each other, and the two pill-forming stations are closest to each other. When making pelletized feed, the personnel first place the mixed shell material and core material in the mixing and storage device, and then start to make pellets through the pelletizing device: In the first step, the roller 21 rotates. When a row of mounting holes 211 on the roller 21 rotates to the shell pressing station, the mounting plate 31 drives the filling column 32 to be inserted into the mounting hole 211. During the insertion of the filling column 32, the first starting component 5 drives the push rod 34 to push the filling head 33 to rotate. At this time, one end of the second feed channel 331 on the filling head 33 is connected with the first feed channel 321, and the other end is connected with the inner cavity of the mounting hole 211. The shell material in the storage device enters the first feed channel 321 and then enters the second feed channel 331. Then, the material enters the mounting hole 211 from the second feed channel 331. After a certain amount of material is squeezed in, the first starting component 5 drives the push rod 34 to reset, and the second feed channel 331 is disconnected from the inner cavity of the mounting hole 211. The flat end of the filling head 33 is flush with the end surface of the filling column 32. The pressure head 61 is located outside the filling column 32. The mounting plate 31 continues to drive the filling column 32 to insert into the mounting hole 211, and presses the pressure head 61 into the bottom die groove 221. The shell material forms a "big wipe" shape, and then the mounting plate 31 drives the filling column 32 to withdraw from the mounting hole 211; In the second step, after the roller 21 drives the feed shell to rotate to the filling station, the mounting plate 31 located at the filling station drives a row of filling heads 33 to be inserted into the mounting hole 211, and the first starting component 5 drives the filling head 33 to rotate. One end of the second feeding channel 331 on the filling head 33 is connected with the first feeding channel 321, and the other end is connected with the inner cavity of the mounting hole 211. The core material in the storage device enters the first feeding channel 321, and then enters the second feeding channel 331, and then enters the mounting hole 211 from the second feeding channel 331. After a certain amount of squeezing, the first starting component 5 drives the push rod 34 to reset, the second feeding channel 331 is disconnected from the inner cavity of the mounting hole 211, and the flat end of the filling head 33 is flush with the end face of the filling column 32. The mounting plate 31 continues to drive the filling column 32 to insert into the mounting hole 211, and the core material is pressed tightly into the recess of the feed shell through the filling head 33. Then the mounting plate 31 drives the filling column 32 to withdraw from the mounting hole 211; In the third step, the roller 21 continues to rotate, driving a row of mounting holes 211 filled with core materials to rotate to the pill-making station. At this time, the bottom mold columns 22 located at the two pill-making stations in the two pill-making devices are coaxial with each other. Then, the first driving component 4 located at the pill-making station drives the bottom mold column 22 to slide out of the mounting hole 211, and the two symmetrically arranged bottom mold columns 22 approach each other, so that the two "big wipe"-shaped feed shells at the ends are bonded to each other. Then, the bottom mold column 22 is driven by the first driving component 4 to be retracted into the mounting hole 211, and the pellet-shaped feed adheres to one of the bottom mold columns 22, or directly falls from between the two bottom mold columns 22; In the fourth step, the roller 21 drives the pelletized feed to rotate to the pellet dispensing station, and the first driving assembly 4 drives the bottom mold column 22 to pop out from the mounting hole 211 to shake off the pellet feed, or the pellet feed falls from the bottom mold column 22 by its own gravity and centrifugal force; Step 5: Personnel collect and seal the fallen feed; Thus, after the shell material and the core material are evenly mixed, the digestive enzymes that cannot come into contact with moisture and other core materials are wrapped in the oily outer shell through shell making, filling, and extrusion pelleting, thereby protecting the digestive enzymes from gradually losing their activity due to contact with moisture, and protecting other core materials from mold and deterioration due to contact with moisture. Through the cooperation of the storage device and the pelleting device, the efficiency of granulation is improved on the one hand, and the quality and utilization rate of pellet feed are improved on the other.

[0022] In order to facilitate the separation of the feed shell from the bottom mold column 22, the bottom mold column 22 is made of polytetrafluoroethylene material.

[0023] Reference Figure 1 , Figure 5 and Figure 7In order to drive the bottom mold column 22 to slide in the mounting hole 211, in the present application, the first driving assembly 4 includes an air storage disk 41 and an air pump 42. The air storage disk 41 is coaxially rotatably connected to one end of the roller 21 and is fixed to the bracket 1. A first cavity 411 is defined in the air storage disk 41. The air pump 42 is mounted on the bracket 1 and communicates with the first cavity 411. The bottom mold column 22 and the bottom wall of the mounting hole 211 directly form a second cavity, and the bottom mold column 22 and the mounting hole 211 are elastically slidably connected. In normal state, the volume of the second cavity is a constant value that is not 0; a plurality of third channels 212 are opened along the axial direction of one end of the roller 21, and the plurality of third channels 212 are distributed along the circumference of the roller 21, and each third channel 212 is connected to a row of second cavities. A first air inlet 412 is opened on the air storage disk 41 in the direction of the pill combining station and the pill discharging station, and the third channels 212 can be connected to the first air inlet 412 when the roller 21 rotates; In this way, when the mounting holes 211 in a row on the rotating roller 21 rotate to the pill combining station or the pill discharging station, the third channel 212 is connected to the first air inlet 412, and the airflow in the first cavity 411 instantly enters the third channel 212 from the first air inlet 412 and then enters the second cavity to eject the bottom mold column 22. After the third channel 212 and the first air inlet 412 are misaligned, the air pressure in the second cavity is reduced, and the bottom mold column 22 is restored to its initial position through its elastic sliding connection with the mounting hole 211.

[0024] Reference Figure 1 and Figure 3 In the present application, the material storage device includes a material storage assembly 7, which includes a material storage box 71, a connecting pipe 72 and a conveying member 73. A material storage box 71 is installed on each mounting plate 31, and the material storage box 71 is fixed on the bracket 1. The connecting pipe 72 is a hose, and there are multiple connecting pipes 72. One end of each connecting pipe 72 is connected to the material storage box 71, and the other end passes through the mounting plate 31 and is connected to the first feed channel 321 on the packing column 32. The conveying member 73 is installed on the connecting pipe 72. In the present application, the conveying member 73 is a peristaltic pump; In this way, after the personnel mix the shell material and the core material respectively, they are added into the material storage box 71, and the conveying member 73 conveys the material in the material storage box 71 to the first feeding channel 321 to complete the material feeding.

[0025] Reference Figure 4 and Figure 5 In order to drive the filling head 33 to rotate, in the present application, a rack is provided on the push rod 34, and a plurality of tooth grooves 332 are provided on the filling head 33 along its circumference, and the rack on the push rod 34 meshes with the tooth grooves 332 on the filling head 33; In this way, the first starting component 5 drives the push rod 34 to slide, and the rack on the push rod 34 engages with the tooth groove 332 on the filling head 33, thereby driving the filling head 33 to rotate, thereby controlling the inner cavity of the mounting hole 211 to be connected with the first feed channel 321 through the second feed channel 331.

[0026] Reference Figure 5 Since the stuffing head 33 is hemispherical, in order to limit the stuffing head 33 from rotating in any direction, in the present application, an arc groove 333 is provided on the surface of the stuffing head 33 along the required rotation direction of the stuffing head 33, and the tooth groove 332 on the stuffing head 33 is provided on the bottom wall of the arc groove 333, and the two side walls parallel to the arc groove 333 on both sides of the push column abut against each other, thereby limiting the stuffing head 33 from rotating in any direction.

[0027] Reference Figure 4 and Figure 5 In order to control the rotation of the filling head 33 according to the different steps of discharging and pressing materials after the filling column 32 enters the mounting hole 211, in the present application, a first avoidance groove 2111 is opened on one side of the mounting hole 211, one end of the push rod 34 is located in the filling column 32, and the other end is located outside the filling column 32, and slides with the filling column 32 to move into the first avoidance groove 2111, the push rod 34 is elastically slidably connected with the filling column 32, and the flat end of the filling head 33 is flush with the end of the filling column 32 in normal state; The first starting member assembly includes a push rod 51 and a limit block 52. The push rod 51 is located in the first avoidance groove 2111, and the push rod 51 is elastically rotatably connected to the roller 21. The rotation axis of the push rod 51 and the mounting hole 211 is perpendicular to the sliding direction of the push rod 51. The limit block 52 abuts against the end of the push rod 51 away from the push rod 34, and is used to limit the end of the push rod 51 away from the push rod 34 from rotating toward the axis of the roller 21. The push rod 34 is provided with a wedge-shaped surface on the side facing the axis of the roller 21. When the push rod 34 is inserted into the mounting hole 211 along with the filling column 32, the wedge-shaped surface abuts against the end of the push rod 51 close to the push rod 34. When the push rod 51 is in a normal state, one end of the push rod 51 located in the first avoidance groove 2111 abuts against the limit block 52; Thus, during the process of inserting the packing column 32 into the mounting hole 211: When the packing column 32 is inserted into the mounting hole 211, the wedge-shaped surface of the push rod 34 abuts against one end of the push rod 51 close to the packing column 32. Since the limit block 52 restricts the push rod 51 from rotating, the push rod 51 pushes the push rod 34 to slide toward the side away from the first avoidance groove 2111, driving the packing head 33 to rotate, so that the second feed channel 331 connects the inner cavity of the mounting hole 211 with the first feed channel 321. When the push rod 34 continues to move to the offset push rod 51, the discharge step is completed, and the push rod 34 automatically restores the initial state by relying on its own elastic sliding connection with the packing column 32. After the packing column 32 continues to slide toward the mounting hole 211 to complete the pressing step, the packing column 32 begins to be pulled out of the mounting hole 211. During the process of the packing column 32 being pulled out of the mounting hole 211: After one end of the push rod 34 is located in the first avoidance groove 2111 and abuts against the push rod 51, the end of the push rod 51 located near the packing column 32 starts to rotate toward the side away from the axis of the roller 21, avoiding the moving path of the push rod 34. After the push rod 34 moves to a state of being disengaged from the push rod 51, the push rod 51 returns to its initial state, and the push rod 34 is pulled out of the mounting hole 211 along with the packing column 32. This completes the steps of filling and pressing.

[0028] Reference Figure 1 and Figure 7 In order to control the filling column 32 to be inserted into the mounting hole 211 for filling and pressing by the rotation of the roller 21, the pill forming device also includes a second starting component 8, which includes a first gear 81, a push cam 82, a second gear 83, a third gear 84, a driving member 85, a fourth gear 86 and a prying rod 87. The first gear 81 is coaxially fixed to the end of the roller 21, the push cam 82 is coaxially rotatably connected to the end of the roller 21, the second gear 83 is coaxially fixed to the push cam 82, the third gear 84 is rotatably connected to the bracket 1 and meshes with the second gear 83, and the driving member 85 is fixed to the bracket 1 for driving the third gear 84 to rotate. In this application, the driving member 85 is a motor, and the fourth gear 86 is coaxially fixed to the third gear 84, and the fourth gear 86 is meshed with the first gear 81, and a plurality of tooth-missing areas are provided on the fourth gear 86; the transmission ratio of the fourth gear 86 to the first gear 81 is greater than the transmission ratio between the third gear 84 and the second gear 83; The prying rod 87 is rotatably connected to the bracket 1, and the rotation axis of the prying rod 87 and the bracket 1 is parallel to the rotation axis of the roller 21. One end of the mounting plate 31 is rotatably connected to the prying rod 87, and slides on the prying rod 87 in a direction close to or away from the rotation axis of the prying rod 87 and the bracket 1. The rotation axis of the mounting plate 31 and the prying rod 87 is parallel to the rotation axis of the prying rod 87 and the bracket 1. After the push cam 82 rotates to abut against the prying rod 87, it drives the packing column 32 to be inserted into the mounting hole 211; The mounting plate 31 is elastically slidably connected to the bracket 1, and the packing column 32 is located outside the rotating roller 21 in a normal state; Therefore, when the driving member 85 drives the third gear 84 and the fourth gear 86 to rotate, the fourth gear 86 drives the first gear 81 to rotate, and the first gear 81 drives the roller 21 to rotate. By changing the size and number of the toothless area on the fourth gear 86, the mounting holes 211 of each row on the roller 21 stop rotating for a period of time at each station. At this time, since the third gear 84 and the second gear 83 are kept in meshing state, the push cam 82 continues to rotate. When the top of the push cam 82 abuts against the prying rod 87, the prying rod 87 rotates, driving the mounting plate 31 to move toward the axis of the roller 21. After the push cam 82 rotates to the point where the prying rod 87 is disengaged, the mounting plate 31 drives the filling column 32 to be pulled out of the mounting hole 211 through its own elastic sliding on the bracket 1, and the prying rod 87 also returns to the initial state with the movement of the mounting plate 31 to wait for the next abutment of the push cam 82. Since the roller 21 is in a stopped state while waiting for the filling column 32 to be inserted and during the insertion process, in order for the roller 21 to "catch up" with the rotation of the push cam 82 after the roller 21 resumes rotation, to ensure that the next time the push cam 82 abuts against the prying rod 87, a row of mounting holes 211 on the roller 21 are in place in advance to wait for the insertion of the filling column 32, in the present application, the transmission ratio of the third gear 84 and the second gear 83 is smaller than the transmission ratio of the fourth gear 86 and the first gear 81, so that the rotation speed of the roller 21 is greater than the rotation speed of the push cam 82.

[0029] Reference Figure 1 In order to stabilize the lifting process of the mounting plate 31 , a second starting assembly 8 is provided at each end of the roller 21 .

[0030] Reference Figure 1 and Figure 7 In order to increase the number of simultaneous operations at multiple stations, in the present application, the push cam 82 is provided with a plurality of vertices that are consistent with the number of columns of the mounting holes 211, so that the mounting plate 31 can work simultaneously at the shell pressing station and the filling station.

[0031] Reference Figure 5 In order to facilitate the chickens to grind and crush the shell feed better, a plurality of recessed holes 222 are opened on the wall of the bottom mold groove 221; Thus, when the feed shell is pressed, a plurality of protrusions are formed on the surface of the shell, so that the shell feed can be ground and crushed by gravel in the crop of the chicken.

[0032] Reference Figure 5 , Figure 6 and Figure 7On the other hand, in order to separate the formed particles from the bottom mold column 22, a third cavity 223 connected to the recessed hole 222 is provided in the bottom mold column 22. The third cavities 223 in a row of bottom mold columns 22 are connected through a connecting pipe 23. The inlet end of the connecting pipe 23 is located at the end of the roller 21. A second air inlet 413 connected to the first cavity 411 is provided on the air storage plate 41. The second air inlet 413 is located at the pellet ejecting position. The inlet end of the connecting pipe 23 can be connected to the second air inlet 413 as the roller 21 rotates. In order to adapt to the sliding of the bottom mold column 22, the connecting section between the connecting pipe 23 and the third cavity 223 is a flexible pipe to adapt to the length change. Thus, when a row of mounting holes 211 rotates to the pellet discharging position, the inlet end of the connecting pipe 23 located at the end of the roller 21 is connected to the second air inlet 413. At this time, the gas in the first cavity 411 enters the third cavity 223, and the gas is discharged from the recessed hole 222 to blow off the formed pellet feed.

[0033] Reference Figure 1 In order to collect the fallen pellet feed, a collecting trough 9 is provided below the pelletizing device. The collecting trough 9 is tilted on the bracket 1 with the notch facing upwards. Two pellet dispensing stations are located directly above the notch of the collecting trough 9.

[0034] Reference Figure 1 In order to further reduce the moisture content of the pellet feed, a heating pad 91 is provided on the inner bottom wall of the collecting tank 9 to heat and dry the pellet feed.

[0035] On the other hand, the present application provides a method for preparing a premixed pellet feed for increasing egg production of laying hens, the specific steps of which are as follows: S1. Pre-drying of each component of the feed in stock; Separating the shell components from the components inside the shell; S2, crushing the granular material components into powder; S3, placing the separated feed in a premixed granular feed preparation device for improving egg production of laying hens in right 2 for pelleting; S4, drying the pelletized feed again at a temperature lower than the temperature that destroys the activity of digestive enzymes; S5, packing the dried pellet feed into bags and sealing them.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
