Description

Technical Field

[0001] This invention belongs to the field of feed production technology, specifically a feed mixing device and mixing method. Background Technology

[0002] Feed mixing equipment is used to mix various raw materials in a certain proportion during the feed production process. It involves putting the weighed main ingredients into the mixing tank and adding auxiliary additives during the stirring and mixing process.

[0003] In existing feed mixing devices, after the weighed main raw materials are added, amino acid supplements, mineral and vitamin premixes, and additives also need to be added. However, current addition methods usually involve a one-time addition. Given that the total amount of auxiliary materials is relatively small, a long mixing time is required during a single addition to ensure that the auxiliary materials are completely and evenly mixed into the total proportion of raw materials. Furthermore, current stepwise addition methods usually use a top-feeding approach, which results in a long mixing time required for the auxiliary materials added at the top to mix with the main raw materials, leading to low actual mixing efficiency and poor performance.

[0004] Furthermore, in existing feed mixing devices, after completing the proportioning and mixing, some feed ingredients are in powder form during the subsequent bottom opening and discharge process. These powdery materials adhere to the inner wall of the mixing tank after being mixed. As the discharge process continues, some feed powder remains attached and is difficult to completely discharge, resulting in a certain deviation in the actual proportioned feed discharged. The powdery material attached to the mixing tank is missing, reducing the proportioning accuracy and leading to poor performance. Summary of the Invention

[0008] Preferably, the rotating shaft is rotatably sleeved inside the top seat. The rotating assembly includes a motor frame, a motor, and a fixed shaft. The motor frame is fixedly connected to the top of the top seat, the motor is fixedly installed inside the motor frame, and the fixed shaft is fixedly connected to the output shaft of the motor. The lower end of the fixed shaft is fixedly connected to the rotating shaft.

[0009] Preferably, the top of the outer surface of the mixing cylinder is provided with a feed inlet, which is connected to the curved pipe. A fixing ring is fixedly sleeved inside the mixing cylinder. A strike rod is fixedly connected to the inner side of the movable plug. One end of the strike rod passes through the fixing ring and the mixing cylinder and extends to the outside. The spray outlets are distributed around the outside of the mixing cylinder.

[0010] Preferably, the number of curved tubes and dispensing cylinders are the same and they are all distributed in a ring at equal intervals on the outer surface of the tank, and the height of the inner end of the curved tube is lower than the height of the outer end.

[0011] Preferably, the top surface of the top seat has a top opening, a filter screen sleeve is movably fitted inside the top opening, and an oblique hole is opened below the outer surface of the tank body. The oblique hole is connected to the air pipe, and one end of the oblique hole is inclined upward.

[0012] Preferably, the jet assembly includes an expansion cylinder, a push plate, a connecting shaft, and a one-way valve. A central rod is fixedly connected to the side of the expansion cylinder and is fixedly connected to the tank body. The push plate is movably sleeved inside the expansion cylinder. One end of the connecting shaft is fixedly connected to the push plate, and the other end of the connecting shaft passes through the expansion cylinder and the sleeve and is fixedly connected to the movable rod. The one-way valve is fixedly installed on the end face of the expansion cylinder, and the bottom of the expansion cylinder is fixedly connected to the air pipe.

[0013] Preferably, the opening and closing assembly includes a support block, a second spring, a round rod, and a sealing plate. The support block is fixedly connected to the inside of the air tube, the second spring is fixedly connected to the top surface of the support block, the round rod is fixedly connected to the other end of the second spring, and the sealing plate is fixedly connected to the top surface of the round rod. The sealing plate is movably fitted into the oblique hole.

[0014] A feeding method using a feed mixing device includes the following steps:

[0015] Step 1: Put the weighed main raw materials of the feed into the tank, and place different auxiliary materials into the feed hoppers of each group. The auxiliary materials enter the inside of the mixing cylinder through the curved tube. Start the rotating component, so that the motor in the rotating component drives the rotating shaft to rotate through the fixed shaft, so that the first spiral blade and the second spiral blade rotate to complete the stirring and mixing. At the same time, the cam sleeve between the first spiral blade and the second spiral blade rotates.

[0016] Step 2: As the cam sleeve rotates continuously, when the protruding end of the cam sleeve contacts the corresponding push rod on the outside, the corresponding push rod drives the movable plug to move instantaneously along the inside of the mixing cylinder, so that the movable plug quickly compresses the space along the inside of the mixing cylinder, and squeezes out the powdered additives along the spray nozzle. As the rotation continues, multiple sets of ingredients are added intermittently in sequence, and the continuous proportioning of auxiliary ingredients is completed.

[0017] Step 3: As the push rod drives the movable plug to move and compress intermittently, the air in the jet assembly is compressed through the movable rod during the compression. The gas is then injected obliquely upward into the tank through the air pipe and the opening and closing assembly, causing the airflow injected into the tank to blow and stir the ingredients.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. This invention fixes a sleeve and a curved pipe to the outer surface of the tank, and adds a dispensing cylinder inside the tank. The dispensing cylinder is connected to the sleeve and the curved pipe. A separate space is reserved on the rotating shaft to install a cam sleeve. In conjunction with the push rod and movable plug in the dispensing cylinder, when the rotating shaft rotates to mix the feed, the cam sleeve rotates intermittently to push the outer push rod. At the moment of pushing, the movable plug moves and compresses the space in the dispensing cylinder, pushing out the auxiliary dispensing material introduced into the dispensing cylinder through the curved pipe. This achieves the addition of auxiliary dispensing material from inside the main raw materials, thereby achieving rapid and effective mixing under the combined effect of rotation. At the same time, the continuous rotation of the cam sleeve and the elasticity of the No. 1 spring allow the dispensing cylinder to be continuously and automatically replenished with auxiliary dispensing material and sprayed in from the inside. By feeding auxiliary dispensing material in small amounts multiple times from inside the tank, the mixing time is greatly shortened and the mixing efficiency is improved.

[0020] 2. This invention utilizes the rotation of a cam sleeve to push the outer push rod to move intermittently laterally. While the powdered auxiliary ingredients are extruded and squeezed out during the lateral movement, the moving plug and the moving rod push the connecting shaft and push plate in the jet assembly to move. In the expansion cylinder, the push plate moves instantaneously to compress the internal space. With the one-way valve maintaining a one-way seal, incompressible air is instantly pushed into the air pipe and pushes the sealing plate in the opening and closing assembly. As the sealing plate is pushed out from the oblique hole, the compressed air is instantly sprayed into the tank. In conjunction with the oblique holes distributed around the tank, the feed material is blown obliquely upward from the inside of the tank, further providing the jet stirring effect in different directions, enhancing the mixing effect, and improving the mixing speed of the formula.

[0021] 3. This invention utilizes the rotation of the cam sleeve to achieve intermittent lateral movement of the push rod and movable plug. After the formula is mixed and discharged, the gas inside the mixing cylinder is intermittently ejected, simultaneously causing the impact rod to intermittently strike the inside of the tank. Furthermore, the jet assembly intermittently injects airflow into the tank again. Through the combined action of vibration and airflow purging, the adhering particulate material on the inner wall of the tank is thoroughly discharged after discharge. This avoids additional cleaning operations while ensuring that all materials are collected in a single batch of formula mixing. It prevents the lack of adhering particulate material from affecting the accuracy of the feed formula ratio and effectively prevents residual material from oxidizing and corroding, thus affecting the quality of subsequent feed.

[0033] 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.

[0034] like Figures 1 to 10As shown, this embodiment of the invention provides a feed dispensing device and method, including a tank 1, a top seat 2 fixedly connected to the top of the tank 1, a rotating shaft 3 rotatably connected inside the tank 1, a first spiral blade 4 and a second spiral blade 5 respectively fixedly sleeved on the outer surface of the rotating shaft 3, a cam sleeve 6 fixedly sleeved on the outer surface of the rotating shaft 3, a rotating assembly 7 fixedly installed on the top of the top seat 2, the rotating assembly 7 being fixedly connected to one end of the rotating shaft 3, and a sleeve 8 and a curved tube 10 respectively fixedly sleeved on the outer surface of the tank 1, the outer end of the curved tube 10 being fixedly... A feed hopper 11 is fixedly connected to the inner end of the sleeve 8, and a dispensing cylinder 9 is fixedly connected to the inner end of the sleeve 8. The top of the dispensing cylinder 9 is connected to the curved pipe 10. A movable plug 14 is movably sleeved inside the dispensing cylinder 9. A push rod 15 and a movable rod 16 are fixedly connected to the two sides of the movable plug 14, respectively. An outlet 18 is opened on the outer surface of the dispensing cylinder 9. A first spring 17 is fixedly connected inside the sleeve 8. The first spring 17 is fixedly connected to the movable rod 16. An air jet assembly 19 is provided at the outer end of the movable rod 16. An air jet assembly 19 is fixedly connected to the tank 1 by an air pipe 22.

[0035] First embodiment: The weighed main raw materials of the feed are put into the tank 1, and different auxiliary materials are placed in the feed funnels 11 respectively. The auxiliary materials enter the interior of the mixing cylinder 9 through the curved pipe 10 and the feed inlet 12. The rotating component 7 is started, so that the motor 72 in the rotating component 7 drives the rotating shaft 3 to rotate through the fixed shaft 73, so that the first spiral blade 4 and the second spiral blade 5 rotate. As the first spiral blade 4 and the second spiral blade 5 rotate, the internal stirring and mixing is completed. At the same time, the cam sleeve 6 between the first spiral blade 4 and the second spiral blade 5 rotates. As the cam sleeve 6 continues to rotate, when the protruding end of the cam sleeve 6 contacts the corresponding push rod 15 on the outside, the corresponding push rod 15 drives the movable plug 14 to move instantaneously along the interior of the mixing cylinder 9, so that the movable plug 14 moves along the mixing cylinder 9. The internal space of the material cylinder 9 is rapidly compressed, and the powdered additives are squeezed out along the nozzle 18. During the rotation process, multiple sets of auxiliary materials are added intermittently in sequence, and the continuous proportioning of auxiliary materials is completed. When the push rod 15 drives the movable plug 14 to move and compress intermittently, the movable plug 14 drives the connecting shaft 193 in the jet assembly 19 to move laterally through the movable rod 16. The connecting shaft 193 drives the push plate 192 in the expansion cylinder 191 to compress the internal air. The one-way valve 194 keeps it sealed and sprays the gas into the tank 1 obliquely upward through the air pipe 22 and the opening and closing assembly 23. Under the pneumatic thrust, the sealing plate 234 in the opening and closing assembly 23 slides out of the oblique hole 21, so that the airflow injected into the tank 1 blows and agitates the ingredients.

[0036] First, by fixing a sleeve 8 and a curved pipe 10 to the outer surface of the tank body 1, and adding a feeding cylinder 9 inside the tank body 1, the feeding cylinder 9 is connected to the sleeve 8 and the curved pipe 10. A separate space is reserved on the rotating shaft 3 to install a cam sleeve 6. With the push rod 15 and movable plug 14 in the feeding cylinder 9, when the rotating shaft 3 rotates to mix the feed, the cam sleeve 6 rotates intermittently to push the outer push rod 15. At the moment of pushing, the movable plug 14 moves and compresses the space in the feeding cylinder 9, pushing out the auxiliary feed introduced into the feeding cylinder 9 through the curved pipe 10. This achieves the addition of auxiliary feed from inside the main raw materials, thereby quickly and effectively mixing under the combined rotation. At the same time, with the continuous rotation of the cam sleeve 6 and the elasticity of the No. 1 spring 17, the auxiliary feed is continuously and automatically replenished into the feeding cylinder 9 and sprayed in from the inside. By feeding the auxiliary feed in small amounts and multiple times from inside the tank body 1, the mixing time is greatly shortened and the mixing efficiency is improved.

[0037] Furthermore, by using the rotation of the cam sleeve 6 to push the outer push rod 15 to move intermittently, while extruding powdered auxiliary ingredients through the lateral extrusion, the moving movable plug 14 and movable rod 16 push the connecting shaft 193 and push plate 192 in the jet assembly 19 to move. In the expansion cylinder 191, the push plate 192 moves instantaneously to compress the internal space. With the one-way valve 194 maintaining a one-way seal, incompressible air is instantly pushed into the air pipe 22 and pushes the sealing plate 234 in the opening and closing assembly 23. As the sealing plate 234 is pushed out from the inclined hole 21, the compressed air is instantly sprayed into the tank 1. In conjunction with the surrounding inclined holes 21, the feed material is blown obliquely upward from the inside of the tank 1, further providing the jet stirring effect in different directions, enhancing the mixing effect, and improving the mixing speed of the formula.

[0038] Second embodiment: After mixing is completed and the bottom of the tank 1 is opened for discharge, the rotating shaft 3 is kept rotating after discharge. As the cam sleeve 6 rotates, the push rod 15 moves laterally intermittently. The nozzle 18 on the outer side of the mixing cylinder 9 sprays gas intermittently and blows it toward the inner wall of the tank 1. As the movable plug 14 moves, the impact rod 20 moves laterally intermittently and impacts the inner wall of the tank 1, causing the powder attached to the inner wall of the tank 1 to vibrate and fall off. At the same time, when the movable plug 14 and the movable rod 16 move laterally intermittently, the jet assembly 19, together with the air pipe 22, sprays purge air into the tank 1 again, causing the powder particles attached to the inner surface of the tank 1 to quickly detach and fall out.

[0039] First, by rotating the cam sleeve 6 again to achieve intermittent lateral movement of the push rod 15 and the movable plug 14, after the formula is mixed and discharged, the gas inside the mixing cylinder 9 is intermittently ejected, which simultaneously drives the impact rod 20 to intermittently impact the inside of the tank 1. The jet assembly 19 is used again to intermittently inject airflow into the inside of the tank 1. With the combined action of vibration and airflow purging, the adhering particulate material on the inner wall of the tank 1 is thoroughly discharged after discharge, avoiding additional cleaning operations. This ensures that all materials are collected in one batch of formula mixing, preventing the lack of adhering particulate material from affecting the feed formula ratio accuracy. At the same time, it effectively prevents the residual material from oxidizing and corroding, which would affect the quality of subsequent feed.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 10 As shown, the cam sleeve 6 is located between the first spiral blade 4 and the second spiral blade 5. The cam sleeve 6 and the push rod 15 are on the same horizontal plane. The push rod 15 is in contact with the outer surface of the cam sleeve 6. The rotating shaft 3 is rotatably sleeved inside the top seat 2. The rotating assembly 7 includes a motor frame 71, a motor 72 and a fixed shaft 73. The motor frame 71 is fixedly connected to the top of the top seat 2. The motor 72 is fixedly installed inside the motor frame 71. The fixed shaft 73 is fixedly connected to the output shaft of the motor 72. The lower end of the fixed shaft 73 is fixedly connected to the rotating shaft 3. The top of the outer surface of the dispensing cylinder 9 is provided with a feed inlet 12. The feed inlet 12 is connected to the curved tube 10. A fixed ring 13 is fixedly sleeved inside the dispensing cylinder 9. A striker 20 is fixedly connected to the inner side of the movable plug 14. One end of the striker 20 passes through the fixed ring 13 and the dispensing cylinder 9 and extends to the outside. The spray outlet 18 is distributed around the outside of the dispensing cylinder 9.

[0041] During use, by controlling the position of the cam sleeve 6 and the push rod 15, the cam sleeve 6 is rotated to intermittently achieve lateral extrusion, the rotating component 7 provides initial stirring and mixing to complete the batching, the impact rod 20 vibrates the tank 1 itself under intermittent impact to avoid adhesion to the inner wall, and the surrounding distributed spray nozzles 18 improve the spraying effect.

[0042] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the number of curved tubes 10 and dispensing cylinders 9 are the same and they are distributed in a ring at equal intervals on the outer surface of the tank body 1. The height of the inner end of the curved tube 10 is lower than the height of the outer end. The top surface of the top seat 2 is provided with a top opening 24. A filter screen sleeve 25 is movably fitted inside the top opening 24. An oblique hole 21 is provided below the outer surface of the tank body 1. The oblique hole 21 is connected to the air pipe 22. One end of the oblique hole 21 is inclined upward.

[0043] During use, by controlling the number and distribution of the curved tube 10 and the batching cylinder 9, it is ensured that multiple auxiliary ingredients are added in proportion while rotating. The height of both ends of the curved tube 10 is controlled to ensure that the auxiliary ingredients are automatically filled into the batching cylinder 9. The top opening 24 is used to add the main material.

[0044] like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the jet assembly 19 includes an expansion cylinder 191, a pusher plate 192, a connecting shaft 193, and a one-way valve 194. An intermediate rod 26 is fixedly connected to the side of the expansion cylinder 191 and is fixedly connected to the tank body 1. The pusher plate 192 is movably sleeved inside the expansion cylinder 191. One end of the connecting shaft 193 is fixedly connected to the pusher plate 192, and the other end of the connecting shaft 193 passes through the expansion cylinder 191 and the sleeve 8 and is fixedly connected to the movable rod 16. The one-way valve 194 is fixedly installed on the expansion cylinder 191. On the end face of 1, the bottom of the expansion tube 191 is fixedly connected to the air tube 22. The opening and closing assembly 23 includes a support block 231, a second spring 232, a round rod 233 and a sealing plate 234. The support block 231 is fixedly connected to the inside of the air tube 22. The second spring 232 is fixedly connected to the top surface of the support block 231. The round rod 233 is fixedly connected to the other end of the second spring 232. The sealing plate 234 is fixedly connected to the top surface of the round rod 233 and is movably sleeved in the inclined hole 21.

[0045] During use, by utilizing multiple sets of jet components 19 arranged in a circular pattern, auxiliary ingredients are continuously fed in from the inside for mixing, while compressed air is intermittently ejected. In conjunction with the inclined arrangement of the inclined holes 21, the intermittently fed gas is used to assist in stirring the internal materials. The one-way valve 194 opens to draw in ambient air when the push plate 192 is reset, and seals and guides the air to be blown out through the air pipe 22 during compression. Utilizing the elasticity of the second spring 232, the sealing plate 234 is ensured to seal in the inclined hole 21 when the air pressure is removed, preventing material leakage. Furthermore, the area of ​​the support block 231 is smaller than the cross-sectional area of ​​the air pipe 22 to prevent the seal from being blocked. Similarly, the diameter of the round rod 233 is smaller than the diameter of the sealing plate 234.

[0046] A feeding method using a feed mixing device includes the following steps:

[0047] Step 1: Put the weighed main raw materials of the feed into the tank 1, and put different kinds of auxiliary materials into the feed funnels 11 respectively. The auxiliary materials enter the inside of the mixing cylinder 9 through the curved tube 10. Start the rotating component 7, so that the motor 72 in the rotating component 7 drives the rotating shaft 3 to rotate through the fixed shaft 73, so that the first spiral blade 4 and the second spiral blade 5 rotate to complete the stirring and mixing. At the same time, the cam sleeve 6 between the first spiral blade 4 and the second spiral blade 5 rotates.

[0048] Step 2: As the cam sleeve 6 rotates continuously, when the protruding end of the cam sleeve 6 contacts the corresponding push rod 15 on the outside, the corresponding push rod 15 drives the movable plug 14 to move instantaneously along the inside of the mixing cylinder 9, so that the movable plug 14 quickly compresses the space along the inside of the mixing cylinder 9, and squeezes out the powdered additives along the spray nozzle 18. As the rotation continues, multiple sets of ingredients are added intermittently, and the continuous proportioning of auxiliary ingredients is completed.

[0049] Step 3: As the push rod 15 drives the movable plug 14 to move and compress intermittently, the air in the jet assembly 19 is compressed through the movable rod 16 during the compression. The gas is then sprayed obliquely upward into the tank 1 through the air pipe 22 and the opening and closing assembly 23, causing the airflow injected into the tank 1 to blow and stir the ingredients.

[0050] Working principle and usage process: During use, the weighed main feed ingredients are placed into tank 1, and different auxiliary materials are placed in the respective feed hoppers 11. The auxiliary materials enter the feed cylinder 9 through the curved pipe 10 and feed inlet 12. The rotating assembly 7 is started, causing the motor 72 in the rotating assembly 7 to drive the rotating shaft 3 to rotate via the fixed shaft 73, thus rotating the first spiral blade 4 and the second spiral blade 5. As the first spiral blade 4 and the second spiral blade 5 rotate, internal mixing is completed. Simultaneously, the first spiral blade 4 and the second spiral blade 5... The cam sleeve 6 between the blades 5 rotates. As the cam sleeve 6 rotates continuously, when the protruding end of the cam sleeve 6 contacts the corresponding push rod 15 on the outside, the corresponding push rod 15 drives the movable plug 14 to move instantaneously along the inside of the dispensing cylinder 9. This causes the movable plug 14 to rapidly compress the space inside the dispensing cylinder 9, squeezing and spraying the powdered additives along the spray nozzle 18. During the rotation process, multiple sets of auxiliary dispensing materials are added intermittently in sequence, completing the continuous proportioning of auxiliary dispensing materials. Furthermore, as the push rod 15 drives the movable plug 14 to move and compress intermittently, during the movement... During compression, the movable plug 14 drives the connecting shaft 193 in the jet assembly 19 to move laterally via the movable rod 16, causing the connecting shaft 193 to drive the push plate 192 in the expansion cylinder 191 to compress the internal air. The one-way valve 194 remains closed, and the gas is injected obliquely upward into the tank 1 through the air pipe 22 and the opening and closing assembly 23. Under the pneumatic thrust, the sealing plate 234 in the opening and closing assembly 23 slides out of the oblique hole 21, causing the airflow injected into the tank 1 to blow and stir the ingredients. When the mixing is completed, the bottom of the tank 1 is opened for discharge. After discharge, the contents are kept in a closed state. As the rotating shaft 3 rotates, the cam sleeve 6 rotates, causing the push rod 15 to move laterally intermittently. The nozzle 18 on the outer side of the mixing cylinder 9 intermittently sprays gas and blows it toward the inner wall of the tank 1. As the movable plug 14 moves, it drives the impact rod 20 to move laterally intermittently and impact the inner wall of the tank 1, causing the powder adhering to the inner wall of the tank 1 to vibrate and fall off. At the same time, when the movable plug 14 and the movable rod 16 move laterally intermittently, the jet assembly 19, together with the air pipe 22, sprays purge air into the tank 1 again, causing the powder particles adhering to the inner surface of the tank 1 to quickly detach and fall out.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
