[0032] Example 1:

[0033] Please see Figures 1-8 and Figures 13-15 The present invention provides a technical solution:

[0034] A raw material mixing device for pig feed production includes a housing 1, a controller 9, a frame 3, and a mixing structure 2. A proportioning module 4 is installed on the housing 1. The proportioning module 4 includes a material shell 41, which is fixed inside the upper opening of the housing 1. Limiting blocks 42 are fixedly connected to both sides of the inner wall of the material shell 41. A feeding wheel 44 is rotatably connected between a group of limiting blocks 42. A transmission structure 43 is fixedly connected to the inner side of the feeding wheel 44. The transmission structure 43 includes a rotating rod 431. Square grooves 432 are formed on the inner sides of both ends of the rotating rod 431. Square blocks 433 are slidably connected to the inner sides of the square grooves 432. A tensioning device is installed on the inner side of each square groove 432. A spring 434 and a motor 436 are fixedly connected to the upper side of the frame 3. The output shaft of the motor 436 is fixedly connected to the outer side of the square block 433 with splicing blocks 435. A first compression spring 45 is fixedly connected to the inner side of each shell 41. A bearing plate 46 is fixedly connected to the upper end of each first compression spring 45. A closing plate 47 is slidably connected to the opening of a set of shells 41. A linkage module 48 is installed on the lower side of each bearing plate 46. The linkage module 48 includes a square rod 481. A strip plate 482 is fixedly connected to the lower end of each square rod 481. Sliding plates 483 are fixedly connected to both sides of the upper surface of each strip plate 482. A sliding plate 483 is installed on the inner side of each sliding plate 483. The device is equipped with an electric telescopic rod 484, the other end of which is fixedly connected to a limit frame 485. Each limit frame 485 has a scale 486 on its outer side. An inclined guide groove is formed on the inner side of the support plate 46, with the lowest point of the guide groove facing the closing plate 47. The closing plate 47 is slidably connected to the rail opening of the housing 1. The lower end face of the support plate 46 and the upper end face of the closing plate 47 are on the same plane. Multiple material grooves are formed on the inner side of the material wheel 44, arranged at equal angles. Each material groove of the material wheel 44 has the same volume. The raw material can be extracted from the material shell 41 through the guide groove of the support plate 46. The support plate 46 is equipped with... The position allows it to completely discharge the raw materials it carries, and the material trough inside the material wheel 44 allows it to quantitatively convey raw materials after rotation; the two ends of the tension spring 434 are fixedly connected to the outer end face of the square block 433 and the inner wall of the square groove 432, respectively. The outer end face of the square block 433 is in contact with the inner wall of the square groove 432. A set of splicing blocks 435 are interlocked with each other. The limiting frame 485 is set between the splicing block 435 and the rotating rod 431. The tension spring 434 can pull the square block 433 to disengage the splicing block 435 from the other side splicing block 435, while the limiting frame 485 can keep a set of splicing blocks 435 always in contact.

[0035] like Figures 13-15As shown, the stirring structure 2 consists of a stirring frame and a motor. A feeding module 6 is installed on the upper side of the stirring frame of the stirring structure 2. The feeding module 6 includes a fixing block 61, which is fixed to the upper side of the stirring frame of the stirring structure 2. A base 62 is fixedly connected to the upper side of the fixing block 61. A cylinder 63 is fixedly connected to the inner side of the base 62. A connecting plate 64 is fixedly connected to the other end of the cylinder 63. A shell plate 65 is fixedly connected to the upper side of the base 62. A distribution plate 66 is slidably connected to the inner side of the shell plate 65. Connecting blocks 67 are fixedly connected to both sides of the distribution plate 66. A pull rope 68 is fixedly connected between the connecting block 67 and the outer end face of the connecting plate 64. A second compression spring 69 is sleeved on the outer side of each pull rope 68. A guide block is fixedly connected to the inner side of the housing 1. 7. A guide plate 8 is fixedly connected to the inner side of the box 1, so that the guide block 7 and the guide plate 8 cooperate with each other to transfer the proportioned raw materials to the spreading module 6. Through the reciprocating movement and rotation of the distribution plate 66, the raw materials can be evenly dispersed in the box 1. The upper end face of the guide block 7 and the lower end face of the shell 41 are on the same plane. The guide plate 8 is set on the lower side of the guide block 7. The guide plate 8 is a three-plate confluence structure. The confluence end of the guide plate 8 is set directly above the shell plate 65. The shell plate 65 and the distribution plate 66 are both set at an inclined angle. The second compression spring 69 is set between the inner wall of the track groove of the shell plate 65 and the outer end face of the connecting block 67. The position of the guide plate 8 and the guide block 7 allows the raw materials to be conducted from the shell 41 to the shell plate 65.

[0036] Workflow: When using the raw material mixing device for pig feed production, firstly, adjust the various linkage modules 48 of the proportioning module 4 according to the raw material ratio. The controller 9 then controls the extension of the electric telescopic rod 484. The extension of the electric telescopic rod 484 causes each limiting frame 485 to move upwards. The upward distance of each limiting frame 485 is adjusted according to the proportion of each raw material and the scale 486. For example, if the raw material ratio in the left feed hopper 41 is the largest, then the limiting frames 485 on both sides of it need to move upwards the greatest distance; conversely, if the raw material ratio in the right feed hopper 41 is the smallest, then the limiting frames 485 on both sides of it need to move upwards the least. After adjusting each linkage module 48 through the above operations, connect each material shell 41 to the external raw material pipelines. Start the motor 436 through the controller 9. The motor 436, in conjunction with the splicing block 435, causes each rotating rod 431 to rotate. The rotation of the rotating rod 431 drives each material wheel 44 to rotate. The rotation of the material wheel 44 can quantitatively transport the raw material to the upper side of the support plate 46. The accumulation of raw material on the support plate 46 will press down on the support plate 46, causing the support plate 46 to drive the linkage module 48 to move down. The downward movement of the linkage module 48 will drive each limit frame 485 to move down. For some raw materials with a smaller proportion, the linkage... Module 48 and the limiting frame 485 will first disengage from the transmission structure 43. Without the limiting frame 485, the square blocks 433 on both sides of the material shell 41 are pulled by the tension spring 434. The splicing block 435 will disengage from its corresponding splicing block 435, causing the material wheel 44 inside the material shell 41 to stop rotating and stop feeding. This process continues until all material wheels 44 stop rotating, ensuring that all raw materials are properly proportioned and supported on the support plate 46. At this point, the operator can stop the motor 436 and start the mixing structure 2. The rotation of the mixing frame in the mixing structure 2 will drive the spreading module 6 to rotate. Then, the starting cylinder 63... The linkage plate 64 moves back to its original position. The displacement of the linkage plate 64 causes the pull rope 68 to pull the distribution plate 66 to move. The second compression spring 69 allows the distribution plate 66 to return to its original position. Through the above operation, the distribution plate 66 can move while rotating. At this time, by pulling the closing plate 47, the proportioned raw materials in each material shell 41 enter the guide block 7. The inclined surface of the guide block 7 allows the raw materials to enter the shell plate 65 and the distribution plate 66 through the guide plate 8. Because the inclined surface of the shell plate 65 and the rotational displacement of the distribution plate 66 can evenly distribute the proportioned raw materials in the box 1, the raw materials can be fully mixed by the stirring structure 2.

The shifting parts 58 are all set between the protrusions of the metering strip 57. The metering strip 57 can be shifted by the shifting parts 58, so that each displacement of the metering strip 57 represents one revolution of the material wheel 44.

[0040] Workflow: When using a raw material mixing device for pig feed production, firstly, adjust the various linkage modules 48 of the proportioning module 4 according to the raw material ratio. After adjustment, the raw materials can be automatically proportioned through the proportioning module 4. If a problem occurs in the proportion of a certain raw material after automatic proportioning, and a single raw material needs to be added, it can be added through the manual control module 5. First, calculate how many revolutions the feed wheel 44 needs to make based on the amount to be added. Then, rotate the turntable 55 to make the transmission wheel 51, pulley 52, and transmission belt 54 drive the rotating rod 431 to rotate. The rotation of the rotating rod 431 drives the feed wheel 44 to rotate and convey the material. At the same time, the rotation of the turntable 55 will also drive the shifting component 58 to move. The displacement of the shifting component 58 will move the metering bar 57. Each movement of the metering bar 57 represents one revolution of the feed wheel 44. Through the above operations, the manual control module 5 can add a single raw material.
