Description

Technical Field

[0001] This utility model belongs to the field of feed formulation technology for pig farming, and specifically relates to a feed formulation device for pig farming. Background Technology

[0002] In pig farming, feed needs to be formulated with different raw material components according to different growth stages of piglets. Currently, this mainly relies on workers to pour the raw materials into containers and mix them manually. This method not only greatly increases the labor intensity of workers, but also often leads to poor feed formulation quality because it is impossible to accurately control the amount of raw material components. For example, the weighing error of main raw materials such as corn and soybean meal may reach 5%-10%, and the error of trace components such as vitamins is even higher. This can easily cause an imbalance in the nutritional ratio of feed, affect the growth of piglets, and even cause diseases.

[0003] The feed proportioning equipment disclosed in Chinese Patent No. CN211411885U, while capable of quantitative feeding through storage space and scale markings, and crushing large raw materials, has significant defects in the mixing process. Its mixing chamber relies solely on a bottom auger for stirring, resulting in a simple mixing structure that only allows for horizontal pushing and lacks vertical turning. This makes it difficult for upper-layer raw materials to effectively participate in mixing, and raw materials with large density differences are prone to "stratification." Furthermore, the lack of a dispersing structure in the mixing chamber prevents the breaking down and dispersion of clumps, easily leading to abnormal local raw material concentrations. In addition, the single auger's stirring speed is slow, resulting in poor mixing uniformity and requiring a long time to complete one mixing cycle, failing to meet industry standards. Existing feed proportioning and mixing methods have significant shortcomings in terms of labor intensity, proportioning accuracy, and mixing effect. It is evident that existing equipment has a simple mixing structure, poor uniformity, and low efficiency, failing to meet the needs of large-scale, rapid feed proportioning for pigs. Therefore, improvements to the existing technology are necessary. Utility Model Content

[0023] Example

[0024] refer to Figures 1 to 5 This embodiment of a feed proportioning device for pig farming includes a proportioning and mixing box 1. An electric push rod 2 is fixedly installed on the rear side of the proportioning and mixing box 1. An upper stirring mechanism 3 is fixedly installed on the output end of the electric push rod 2. The bottom of the upper stirring mechanism 3 extends into the upper part of the proportioning and mixing box 1. A lower stirring mechanism 6 is movably installed in the lower part of the interior of the proportioning and mixing box 1. A top frame 4 is fixedly installed on the top of the proportioning and mixing box 1.

[0025] The lower stirring mechanism 6 includes a first motor 61, which is fixedly installed at the lower right side of the mixing tank 1. The output end of the first motor 61 passes through the mixing tank 1 and is fixedly mounted with a rotating shaft 62. Both ends of the outer surface of the rotating shaft 62 are fixedly mounted with lower stirring augers 63. The threads of the lower stirring augers 63 at both ends inside the mixing tank 1 rotate in opposite directions. During operation, the electric push rod 2 drives the upper stirring mechanism 3 to vertically rise and fall along the mixing tank 1. Simultaneously, the second motor 334 in the drive assembly 33 drives the lead screw 332 to rotate, causing the slider 333 to reciprocate horizontally along the rail frame 331, thereby synchronously moving the stirring assembly 34. The gear 343 in 34 meshes with the rack 341 at the bottom of the rail frame 331, causing the upper stirring auger 344 to rotate synchronously when moving horizontally, forming a composite motion of translation and rotation, which stirs and pushes the raw materials in the upper layer of the box. At the same time, the first motor 61 of the lower stirring mechanism 6 drives the rotating shaft 62 to rotate, causing the lower stirring auger 63 with opposite threads at both ends to rotate synchronously, forming a convection field with left and right flow at the bottom of the box, which gathers the raw materials towards the center and lifts them upward. The upper and lower stirring mechanisms 6 work together to form a three-dimensional mixing flow of upper light raw materials and lower heavy raw materials in the middle area of ​​the box, which is stirred and pushed downward, and crosses each other, to achieve dynamic mixing in the whole space.

[0026] refer to Figures 1-3A discharge valve 7 is fixedly installed in the middle of the bottom of the mixing tank 1. The input end of the discharge valve 7 is connected to the bottom of the mixing tank 1. The bottom of the mixing tank 1 is generally arc-shaped, and all the external corners of the mixing tank 1 are arc-shaped. Support legs 5 are fixedly installed at the four corners of the bottom of the top frame 4, and a base plate 8 is fixedly installed at the bottom of the support legs 5. During the application of this device, the arc-shaped design of the bottom of the mixing tank 1 forms a precise fit with the lower stirring auger 63 with opposite threads at both ends. When the auger rotates, it can discharge the raw materials at the bottom of the tank without... The mixing process is seamlessly integrated into the corners to avoid material accumulation caused by right-angle structures. The discharge valve 7 in the middle of the bottom is connected to the inside of the box bottom and can be quickly opened after mixing. The rounded bottom guides the material to be discharged smoothly, reducing residue. The external corners of the box are rounded to reduce the risk of material adhesion and facilitate cleaning and maintenance. The top frame 4 is connected to the base plate 8 through four corner support legs 5 to form a stable three-dimensional support structure, ensuring the overall rigidity of the equipment during mixing and preventing vibration from affecting the mixing accuracy or causing displacement. This provides a solid foundation for the coordinated operation of the upper and lower mixing mechanisms 6.

[0027] refer to Figures 3-5The upper stirring mechanism 3 includes a connecting rod 31, which is fixedly installed at the top output end of the electric push rod 2. A top plate 32 is fixedly installed at the outer end of the connecting rod 31. A drive assembly 33 is fixedly installed at the bottom of the top plate 32. Stirring assemblies 34 are installed on both sides of the bottom of the drive assembly 33. The drive assembly 33 includes a rail frame 331, which is fixedly installed at the bottom of the top plate 32. A lead screw 332 is rotatably connected inside the rail frame 331. A slider 333 is threadedly connected to the outer surface of the lead screw 332. A second motor 334 is fixedly installed at one end of the rail frame 331. The output end of the second motor 334 passes through the rail frame 331. One end of the frame 331 and the lead screw 332 are connected. The stirring assembly 34 is installed at the bottom of the slider 333. The stirring assembly 34 includes a rack 341 and a connecting arm 342. The connecting arm 342 is fixedly installed on both sides of the slider 333. A gear 343 is rotatably connected to the bottom outer end of the connecting arm 342. The rack 341 is fixedly installed on both sides of the bottom of the rail frame 331. The gear 343 and the rack 341 are meshed. An upper stirring auger 344 is fixedly installed at the bottom of the gear 343. Support rods 345 are fixedly installed at both the front and rear ends of the bottom sides of the rail frame 331. The bottom of the support rods 345 penetrates the top frame 4. The support rods 345 and... The top frame 4 is slidably connected to each other. During the application of this device, the working principle of the upper stirring mechanism 3 is based on the coordinated cooperation of multiple components. The electric push rod 2 drives the connecting rod 31, which drives the top plate 32 and its bottom driving component 33 to move vertically up and down, thereby adjusting the height of the upper stirring mechanism 3 in the proportioning mixing box 1 to adapt to different feed filling amounts. In the driving component 33 at the bottom of the top plate 32, after the second motor 334 is started, it drives the lead screw 332 to rotate. The slider 333, which is threadedly connected to the lead screw 332, moves back and forth horizontally in the rail frame 331, thereby driving the stirring component 34 installed at the bottom of the slider 333 to move synchronously. In the translational stirring assembly 34, the connecting arm 342 is connected to the slider 333, and the gear 343 at the bottom outer end meshes with the rack 341 at the bottom of the rail frame 331. When the slider 333 moves horizontally, the gear 343 rolls along the rack 341, driving the upper stirring auger 344 fixed at its bottom to rotate synchronously. Under the combined motion of translation and rotation, the upper stirring auger 344 tumbles and pushes the upper raw materials of the proportioning mixing box 1. At the same time, the support rod 345 at the bottom of the rail frame 331 passes through the top frame 4 and can slide relative to it, providing guidance and support for the movement of the entire upper stirring mechanism 3, ensuring the stability and accuracy of the operation process.

[0028] Operating principle and advantages: This feed proportioning device achieves efficient mixing through the linkage design of the upper stirring mechanism 3 and the lower stirring mechanism 6. The electric push rod 2 drives the upper stirring mechanism 3 to move vertically up and down along the proportioning mixing box 1, facilitating its inspection and maintenance. At the same time, the second motor 334 in the drive assembly 33 drives the lead screw 332 to rotate, causing the slider 333 to move horizontally back and forth along the rail frame 331, thereby driving the stirring assembly 34 to move synchronously. The gear 343 in the stirring assembly 34 meshes with the rack 341 at the bottom of the rail frame 331, so that the upper stirring auger 344 moves horizontally. The moving mechanism rotates synchronously, forming a composite motion of translation and rotation, which tumbles and pushes the raw materials in the upper layer of the box. The first motor 61 of the lower stirring mechanism 6 drives the rotating shaft 62 to rotate, causing the lower stirring auger 63 with opposite threads at both ends to rotate synchronously, forming a convection field with left and right flowing in opposite directions at the bottom of the box, which gathers the raw materials towards the center and lifts them upward. The upper and lower stirring mechanisms 6 work together to form a three-dimensional mixing flow of upper light raw materials such as wheat bran and lower heavy raw materials such as minerals in the middle area of ​​the box, which is stirred upward and pushed downward, and cross-shaped, achieving dynamic mixing in the whole space.

[0029] During the application of this device, the compound motion of the upper stirring mechanism 3 covers the entire upper area of ​​the box. The spiral blades of the rotating auger tumble and horizontally cut the raw materials downwards, breaking the limitation of static materials in the upper layer of traditional equipment. The reverse auger convection design of the lower stirring mechanism 6 eliminates the bottom mixing dead zone, pushing heavy raw materials upwards and forcibly mixing them with the light raw materials falling from the upper layer. This effectively solves the stratification problem caused by density differences, significantly improving mixing uniformity. Simultaneously, the upper stirring auger 344 exerts a shearing effect on agglomerated raw materials during its movement and rotation, breaking up the mixture. The agglomeration formed during the mixing process ensures that the raw material particles are evenly dispersed. The coordinated convection of the upper and lower stirring mechanisms 6 shortens the material mixing path, reduces ineffective mixing time, and significantly improves mixing efficiency compared to traditional single auger equipment. The electric push rod 2 can adjust the height of the upper stirring mechanism 3 to adapt to the filling amount of different batches of feed and meet the needs of rapid formula switching for piglets at different growth stages. The arc-shaped box bottom fits precisely with the edge of the auger, reducing material retention and facilitating cleaning. The support legs 5 and the base plate 8 enhance the stability of the equipment. The overall structure takes into account both energy saving and ease of operation.
