DETAILED DESCRIPTION

[0036] Reference Figure 1-Figure 9 The present invention provides a feed production mixing device and a method for using the same, comprising a stirring tank 1, wherein a stirring chamber is provided in the stirring tank 1, a stirring shaft 2 is rotatably installed in the stirring chamber, and a plurality of stirring blades 3 are rotatably installed on the periphery of the stirring shaft 2; a driving structure for driving the stirring shaft 2 to rotate in the stirring chamber is also installed on the stirring tank 1. When the feed is mixed, the driving structure drives the stirring shaft 2 and the stirring blades 3 to rotate and stir and mix the various raw materials in the stirring chamber. In actual situations, multiple groups of stirring shafts 2 and stirring blades 3 can be arranged in the stirring chamber for stirring, so that the mixing is more uniform.

[0037] like Figure 2 , Figure 3 and Figure 4As shown in the figure, the stirring blade 3 is fixedly connected to the rotating shaft 4, and the outer periphery of the stirring shaft 2 is provided with a rotating hole adapted to the rotating shaft 4, and the rotating shaft 4 is rotatably installed in the rotating hole; an adjusting structure is also installed on the stirring tank 1, and when the stirring shaft 2 rotates and rises, the adjusting structure can adjust the rotating shaft 4 to rotate on the stirring shaft 2; during the stirring process, the inclination angle of the stirring blade 3 is gradually changed by adjusting the adjusting structure, thereby adjusting the stirring area of ​​the stirring blade 3, controlling the shear force, and achieving better pushing effect, etc., so as to achieve better stirring effect; in addition, the appropriate angle of the stirring blade 3 can be adjusted according to the type of material, and the adaptability is stronger.

[0038] In actual situations, changing the inclination angle of the stirring blade 3 has the following advantages:

[0039] 1. Improve mixing efficiency: By adjusting the inclination angle of the stirring blade 3, the effect of the stirrer on the mixture can be optimized. The appropriate inclination angle can make the stirring blade 3 have a better cutting and pushing effect on the fluid, thereby improving the mixing efficiency;

[0040] 2. Improve uniformity: Changing the inclination angle of the stirring blade 3 helps to obtain a more uniform mixture. In some applications, adjusting the angle of the stirring blade 3 can reduce the dead zone, reduce the sedimentation of the material in the stirring container, and ensure uniform mixing of the material;

[0041] 3. Control shear force: The magnitude of shear force directly affects the viscosity and stability of the material. By changing the angle of the stirring blade 3, the shear force generated by the stirrer can be adjusted to avoid excessive shearing of certain materials and maintain their structure and performance;

[0042] 4. Adapt to different materials: Different materials may require different stirring conditions. The stirring blade 3 with adjustable inclination angle can adapt to the stirring requirements of different materials, such as high-viscosity materials or materials that are easy to precipitate. The stirring process can be optimized by adjusting the angle;

[0043] 5. Energy saving and consumption reduction: Optimizing the angle of the stirring blade 3 can reduce energy consumption, because improper stirring will lead to energy waste. The appropriate tilt angle can enable the stirrer to obtain better stirring effect at a lower energy input;

[0044] 6. Improve production efficiency: By quickly achieving the required mixing effect, the mixing time is reduced, thereby improving production efficiency;

[0045] 7. Enhance equipment flexibility: The stirring device can quickly adjust the angle of the stirring blade 3 according to different production requirements, thereby improving the flexibility and adaptability of the equipment.

[0046] like Figure 2 , Figure 3 and Fig. 9As shown in the figure, a lifting structure is installed on the stirring tank 1, and the lifting structure can make the stirring shaft 2 move up and down during the rotation process; during the stirring process, the stirring intensity and mixing depth can be changed by adjusting the lifting height of the stirring blade 3, thereby optimizing the stirring process and improving the stirring efficiency; for materials of different viscosities or different capacities, the stirring blade 3 can adjust the contact degree with the material by lifting and lowering, thereby adapting to various stirring needs.

[0047] like Figure 2 , Figure 4 and Figure 5 As shown in the figure, a positioning structure is installed on the stirring shaft 2, and the positioning structure is used to fix the position of the rotating shaft 4 on the stirring shaft 2; during the stirring process, the positioning structure fixes the inclination angle of the rotating shaft 4 and the stirring blade 3 to ensure the shear force and thrust of the stirring blade 3 on the material.

[0048] like Figure 2 , Figure 3 and Fig. 9 As shown in the figure, the lifting structure includes a lifting block 5 and a rotating block 6; the top view of the lifting block 5 is an arc shape, and the two sides of the lifting block 5 are multiple arc slopes. The shape of the rotating block 6 is similar to that of the lifting block 5. Figure 3 It is shown in the figure that a top connecting block 7 is fixedly installed on the top of the stirring tank 1, and a lifting hole adapted to the stirring shaft 2 is opened at the bottom of the top connecting block 7, and the top of the stirring shaft 2 slides through the top of the stirring tank 1 and can rotate in the lifting hole; a bottom connecting block 8 is fixedly installed on the bottom of the stirring tank 1, and a movement hole is opened at the top of the bottom connecting block 8, and the bottom end of the stirring shaft 2 slides through the bottom end of the stirring tank 1 and can rotate in the movement hole, the lifting block 5 is fixedly installed on the bottom inner wall of the movement hole, and the rotating block 6 is fixedly connected to the bottom of the stirring shaft 2. At the end, the rotating block 6 can slide with the lifting block 5. When the stirring shaft 2 rotates, the stirring shaft 2 drives the rotating block 6 to rotate synchronously. When the rotating block 6 is not in contact with the lifting block 5, the stirring shaft 2 is in the lowest position. When the rotating block 6 rotates and abuts against the side of the lifting block 5, the inclined surfaces of the two slide and cooperate, and the rotating block 6 gradually rises along the inclined surface of the lifting block 5, thereby driving the stirring shaft 2 and the stirring blade 3 to rise, thereby changing the height of the stirring blade 3; the setting of the top connecting block 7 and the bottom connecting block 8 is used to provide space for the lifting and lowering of the stirring shaft 2.

[0049] like Figure 2 , Figure 4 and Figure 5As shown in, the adjustment structure includes a transmission bevel gear 9, an adjustment rod 10, a clamping block 11 and an active bevel gear 12; a cavity is provided in the stirring shaft 2, one end of the rotating shaft 4 passes through the stirring shaft 2 and extends into the cavity and is fixedly connected to the transmission bevel gear 9, the bottom end of the adjusting rod 10 is installed on the bottom inner wall of the motion hole, and a stabilizing hole adapted to the adjusting rod 10 is provided on the top inner wall of the cavity, the adjusting rod 10 can be lifted and rotated in the stabilizing hole to increase the stability of the adjusting rod 10, the clamping block 11 can be set to a bevel gear structure, and a clamping groove adapted to the clamping block 11 is provided in the middle position of the active bevel gear 12, the clamping block 11 is fixedly sleeved on the adjusting rod 10, the active bevel gear 12 is rotatably installed in the cavity, and the active bevel gear 12 is meshed with the transmission bevel gear 9, and the clamping block 11 can be clamped with the active bevel gear 12 Next, in the specific operation process, when adjusting the rotation of the stirring blade 3, the stirring shaft 2 and the stirring blade 3 are raised, and the stirring shaft 2 drives the rotating shaft 4, the transmission bevel gear 9, and the active bevel gear 12 to rise synchronously. When the active bevel gear 12 is raised, the active bevel gear 12 is sleeved on the clamping block 11, and the teeth on the clamping block 11 are clamped into the teeth in the clamping groove to complete the clamping. Since the stirring shaft 2 is in a rotating state, there is a speed difference between the adjusting rod 10 and the stirring shaft 2, that is, there is a speed difference between the driving bevel gear 12 and the transmission bevel gear 9 (the active bevel gear 12 is regarded as a stationary state, the stirring shaft 2 drives the transmission bevel gear 9 to make a circular motion, and while the transmission bevel gear 9 makes a circular motion, it generates self-rotation and drives the rotating shaft 4 and the stirring blade 3 to rotate, thereby changing the inclination angle of the stirring blade 3), thereby changing the inclination angle of the stirring blade 3.

[0050] In actual operation, the speed of adjusting the inclination of the stirring blade 3 may be adjusted according to the different raw materials of the processed feed, and the adjustment structure also includes an adjustment motor 13; the adjustment motor 13 is fixedly installed at the bottom end of the bottom connecting block 8, and the output shaft of the adjustment motor 13 is fixedly connected to the bottom end of the adjustment rod 10, and the adjustment motor 13 drives the rotation of the adjustment rod 10 to adjust the rotation difference and rotation direction between the adjustment rod 10 and the stirring shaft 2, so as to facilitate the control of the inclination change speed of the stirring blade 3 and the inclination adjustment direction according to actual conditions.

[0051] In actual situations, when the stirring shaft 2 is stirring at a low position, the clamping block 11 and the active bevel gear 12 are in a disengaged state. Under the reverse thrust of the material on the stirring blade 3, the stirring blade 3 may rotate on its own. Therefore, in this state, the inclination angle of the stirring blade 3 needs to be fixed to ensure the stirring of the feed.

[0052] like Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown in the figure, the positioning structure includes a mounting ring 14 and a rotating positioning rod 15; the mounting ring 14 is fixedly mounted on the inner wall of the inner cavity, a gear ring 16 is fixedly connected to the active bevel gear 12, a positioning tooth groove is circumferentially provided on the top surface of the gear ring 16, a rotating groove that rotates with the gear ring 16 is provided at the bottom of the mounting ring 14, a positioning groove that is connected to the rotating groove is provided on the inner ring wall of the mounting ring 14, and the rotating positioning rod 15 is rotatably mounted in the positioning groove through a rotating shaft, and a torsion spring is mounted on the rotating shaft of the rotating positioning rod 15. One end of the positioning rod 15 can be inserted into the positioning tooth groove on the gear ring 16, and the structure of the gear ring 16 is similar to the end gear; the torsion spring is used to drive the end of the rotating positioning rod 15 to rotate and disengage from the positioning tooth groove, and the mounting ring 14 is sleeved on the outer periphery of the adjusting rod 10, and the inner diameter of the mounting ring 14 is larger than the diameter of the adjusting rod 10. When the stirring shaft 2 descends, the clamping block 11 can enter the mounting ring 14 and push the rotating positioning rod 15 to rotate and snap into the positioning tooth groove. When the stirring blade 3 is in a low position and rotates, the clamping block 11 1 and the active bevel gear 12 are in a disengaged state. As the stirring shaft 2 descends, the clamping block 11 moves upward relative to the active bevel gear 12. The mounting ring 14 is fixedly mounted on the inner wall of the inner cavity of the stirring shaft 2 (the mounting ring 14 and the stirring shaft 2 rise and fall synchronously). The clamping block 11 enters the mounting ring 14 and lifts up one end of the rotating positioning rod 15. The other end of the rotating positioning rod 15 rotates and is clamped into the positioning tooth groove on the end face of the gear ring 16, thereby clamping the rotation of the gear ring 16, and the gear ring 16 restricts the active bevel gear 1 2, since the transmission bevel gear 9 and the active bevel gear 12 are in a meshing state, the rotating shaft 4 and the stirring blade 3 are in a fixed state, and their inclination cannot be changed. However, when the stirring blade 3 is raised, the clamping block 11 moves downward compared to the mounting ring 14, and the rotation positioning rod 15 is not lifted by the clamping block 11. Under the action of the torsion spring, the rotation positioning rod 15 is driven to rotate, and the other end of the rotation positioning rod 15 is disengaged from the positioning tooth groove, ensuring that the rotation of the active bevel gear 12 is not restricted.

[0053] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, the driving structure includes a stirring motor 19, which is fixedly mounted on the top of the top connecting block 7. The output shaft of the stirring motor 19 passes through the top connecting block 7 and extends into the lifting hole. A hexagonal rod 20 is fixedly mounted on the output shaft of the stirring motor 19. A hexagonal hole 21 matching the hexagonal rod 20 is provided at the top of the stirring shaft 2. The hexagonal rod 20 can be lifted and lowered in the hexagonal hole 21; the hexagonal rod 20 can be lifted and lowered in the hexagonal hole 21, thereby ensuring the lifting and lowering movement of the stirring shaft 2, and at the same time ensuring that the stirring motor 19 drives the hexagonal rod 20 to rotate to drive the stirring shaft 2 to rotate.

[0054] like Figure 1 and Figure 2As shown in FIG. 1 , a feed pipe 17 and a discharge pipe 18 are also installed on the mixing tank 1 ; the feed pipe 17 is located above the discharge pipe 18 and is used for feeding and discharging feed.

[0055] The hybrid method is as follows:

[0056] Step 1, injecting a variety of raw materials into the stirring chamber of the stirring tank 1 through the feeding pipe 17;

[0057] Step 2, the stirring motor 19 drives the stirring shaft 2 and the stirring blade 3 to rotate to stir and mix the raw materials in the stirring chamber. When the stirring shaft 2 rotates, the rotating block 6 is driven to rotate synchronously. When the rotating block 6 contacts the lifting block 5, the rotating block 6 can move upward along the inclined surface of the lifting block 5, driving the stirring shaft 2 and the stirring blade 3 to rise synchronously; when the stirring shaft 2 rises, the clamping block 11 descends and clamps into the active bevel gear 12, and at the same time, the rotating positioning rod 15 is not supported by the clamping block 11, and the rotating positioning rod 15 is moved upward. The positioning tooth groove is disengaged. When the stirring shaft 2 rotates, the active bevel gear 12 is stuck by the clamping block 11 and cannot rotate, and the transmission bevel gear 9, the rotating shaft 4 and the stirring blade 3 rotate to change the inclination angle; when the rotating block 6 slides down along the inclined surface of the lifting block 5, the rotating positioning rod 15 rotates and resets to clamp the positioning tooth groove on the gear ring 16 to clamp the active bevel gear 12, thereby fixing the rotation of the active bevel gear 12, the transmission bevel gear 9, the rotating shaft 4 and the stirring blade 3, and at the same time the clamping block 11 is disengaged from the active bevel gear 12;

[0058] Step 3: Discharge the uniformly mixed raw materials from the discharge pipe 18.

[0059] In step 2, the adjusting motor 13 can drive the adjusting rod 10 to rotate, thereby changing the amplitude and direction of the inclination angle of the stirring blade 3. In addition, in actual use, the rotation direction of the output shaft of the stirring motor 19 can also be controlled to change the inclination direction of the stirring blade 3 and then perform stirring, so as to stir the feed raw materials in the stirring tank 1 in the opposite direction, so as to achieve a better stirring effect.

[0060] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
